LED Digital Electronic Message Center Signs and Video Displays are also known as LED
Signs, Display Signs, Jumbotron Signs, Changeable
Signs, Changeable Letter Signs, Scrolling Signs,
Marquee Signs, and Readerboard Signs, among others.
Electronic message centers and video displays help your business many
They allow real-time communication with potential
With almost 20% of the US
population moving in a year, new potential customers
of varying demographics are always viewing your
signs. What is effective now may not be
effective later…or after lunch.
They attract attention through animation and
brightness so they increase awareness of your
business location and your products.
Message center signs are prettier than signs with changeable plastic letters, improving the appearance of your business.
Your message is not limited by the size of your reader board, or to only one message.
Your advertising dollars are invested in selling in
your trade area, preventing excessive advertising
Changing your message, any time you wish, is as easy
as typing. It can be done often and safely.
Quality electronic message center displays are
readable from a further distance, especially is poor
Full color displays are vastly superior to monochrome displays in impressing potential customers. Fortunately they are no longer vastly more expensive!
You increase your employee's safety vs.
conventional letter-changing poles and plastic letters. Walgreen's Drug
Stores changed from manual readerboards to Electronic Message Centers
partially for employee safety. We were an expert witness in one such
tragedy leading to this change.
An electronic message center or video display will make your message
stand out from the crowd of signs around you.
Even displaying the time and temperature can give a
viewer valuable information which they will associate
with your business. Combining that capability with
animated messages, possibly in color, can really drive
your sales up, 15% to 150%!
Even the Federal Government has determined that signs
containing electronic message centers are safety
enhancing devices, not traffic hazards! This is
why they are used on federal roadways to communicate
Read what the U. S. Small Business Administration (SBA) has to say about the
advantages and costs of signs for your business:
Modern electronic message centers and video displays are illuminated
using LED’s. This lowers their operating cost by
80+% over older, incandescent systems. If the
system is properly designed the bulbs are part of a
modular display board that is easily removable and
changeable, thus helping to control service costs.
The “pitch” or spacing of the LED’s greatly affects
the appearance of the display, and the cost of the
In almost all instances an electronic message center
or video display is built into or attached to additional signs that
contains your name and other permanent information.
You need to work with a sign manufacturer, not just an
electronic message center salesman.
Why Should I Buy from Signs Manufacturing?
Signs Manufacturing is an excellent sign company, we make great signs. But just being a good sign company does not necessarily mean that a company can install and service Video Displays and Electronic Message Centers. They may be able to weld, install fluorescent lamps and roll paint, but can they build, program and service a computer?
Digital LED electronic message centers and video displays are very complicated computers, remotely served by other computers, use proprietary software programs, and are not what most sign company employees, or electricians, understand.
But because these signs are electrical they must be installed by a qualified electrical sign company or an electrical contractor. We are the largest electronic message center manufacturer in North Texas; one of only 3 in the entire State! And we are State licensed as both an electrical sign contractor and as an electrical contractor.
We know what we are doing when it comes to Electronic Message Center and Video Display fabrication and service. We even carry all parts in stock for immediate replacement if something fails.
A large part of our business is repairing mistakes other sign companies and electricians made installing signs they bought and resold to their customers.
"We paid $34,000 for a full-color LED message center from Wal**** Signs & Lighting. It took them 11 months to get it installed. It is now 4 months old and has never worked in full-color mode. They don't know how to make it work. Can you fix it?"
Jack Miller, Grace Point Church
Electronic Message Centers or Video Displays are usually built into additional signage, not installed by themselves. Doing so makes them less expensive and more effective at the same time!
But most electronic message center manufacturers do not manufacture additional types of signs.
Manufacturing makes more than electronic message centers and video displays.
We manufacture, install and service
architectural signs, etc.

Historically monochrome message centers were much cheaper than color video displays. This is no longer true.
In making your decision regarding monochrome vs. color realize that colors in motion are proven to be much more attention-getting than moving single-color lights.
Monochrome (one color) displays are available in “Red”
or “Amber (Yellow).”
Full-Color displays are either RGB (Red, Green, Blue) or
RGBW (Red, Green, Blue, White.)
The more colors, the more LED lights in each pixel,
the larger each pixel, the further back from the sign
you must be so that the sign is not “grainy.”
Display Capability - Palette
Because the intensity of a LED light can be changed by
increasing or decreasing the voltage to it, the better
monochrome displays feature over 4000 shades of
Red or Amber. Some manufacturers call this "grayscale."
The cheaper monochrome displays cannot vary their color intensity at all, they are truly one color. A Sunburst Displays™ sign can turn it's gradients feature "off" and display one-color monotone.
Good color displays (RGB) can display over 260,000
color variations; exceptional units 6 million.
We have units available with
256/4,000/26,000/6,000,000 and 281,000,000,000,000
An electronic message center is in many ways a large
computer screen. The screen is illuminated by
turning many individual lights, or pixels, on/off (or
varying the voltage to them.)
Tighter spacing between pixels allows more data to be
displayed and makes the sign look better but increases
Older generation displays group LEDs in clusters. Modern Sunburst Displays™ utilize balanced spacing and more modern software for a superior appearance.
Pixel Size - Clusters vs. a Balanced Array™
To produce colors at least 3 different color producing LEDs are utilized, Red, Green, and Blue (RGB.) For the human eye, red, green and blue create white.
Older generation displays group LEDs in clusters. A more modern Sunburst Displays™ utilize a Balanced Array™ for a superior appearance because the LEDs are evenly spaced, and more sophisticated software creates "virtual pixels."
Some electronic message center manufacturers try to overcome inferior LED’s (which are greatly less expensive) by adding more than one LED of the same color to each pixel.
This makes the pixel cluster larger, which makes the pitch larger, which increases the minimum viewing distance. It also uses more electricity.
How far pixels are from one another is called
“pitch” and is usually expressed in millimeters (mm.)
The pitch must be small for a display not to appear
grainy up close.
Older color displays, because each pixel is actually an unequal cluster of 3 or more different colored LED’s, cannot have as small a pitch as a monochrome display or the appearance of a more modern display with a Balanced Array™. Therefore they must be viewed from a greater distance to have a quality appearance. There is a lot of blank space between pixels.
Old-style monochrome displays are available in 9mm, 19mm, 25mm, 35mm, 46mm
and larger, some very larger pitches.
The tightest pitch for a quality RGB color display is
The distance between LEDs in Sunburst Displays™ Balanced Array™ can be as small as 6 mm, monochrome or full-color.
How many pixels wide and high the display is, which determines how many of what size letters can be displayed at one time.
Most matrix dimensions are in multiples of 8 pixels, or virtual pixels in the case of a Balanced Array™.
A larger matrix can display more and larger information at one time.
The Advantages of a Balanced Array™
Creates a visually a more attractive sign with evenly spaced LED's.
The software generates 4 LED's per "virtual pixel" which allows:
▪ Illuminating a second red LED in each virtual pixel to create whiter Whites.
▪ Larger pixels and beefier letters containing more illuminated LED's for the same height when compared to a standard array.
Superior reproduction of letter fonts and graphics.
Larger LED's are used, creating a brighter sign with increased "fill" (less space between LED's.)
LED's are 50% closer together than pixels are in a standard array, this provides a much tighter display appearance.
There are 33% more LED's in any given area. More than 1,000 in each square foot of sign face.
One Glare Shield (see below) per LED, rather than one per pixel, maximum.
Software can shift "pixel" locations to compact the vision even further.
As an automobile driver drives toward an electronic message center which is installed on a 20’ tall pole the vertical viewing angle increases from near 0° to almost 90° as the driver passes under the sign. As the viewing angle increases the intensity of the display decreases. The vertical viewing angle of the LED’s used in the display plays an important role in the usefulness of the display. (For more information on this see “Glare Shields or Louvers” below.)
As a driver drives toward an electronic message center installed on the side of a road the horizontal viewing angle increases from near 0° to 90° as the driver passes beside the sign. As the viewing angle increases the intensity of the display decreases in this direction also. The horizontal viewing angle of the LED’s used in the display also plays an important role in the usefulness of the display.
It is important to understand the vertical and the horizontal angle that the display will be viewed from.
LED lights are directional, and Glare Shields or Louvers can block visibility. High quality LED’s can be viewed by as much as 90° horizontally and vertically and still observe over 70% of the lumen potential.
Some LED’s lose virtually all of their light at angles over 45°. Less-expensive signs must therefore be viewed nearly straight-on to be legible.
Sunburst Displays™ are effective at radical angles.
Determining Your Minimum Display Size
Videos will run on any size sign, with a resolution equal to the pixel matrix of the display.
This is not true for wording, however. Signs that have a larger pixel pitch will not be able to display small letters as clearly as a sign with a smaller pixel pitch (smaller pixel pitch means more dots per square foot).
Decide on how many lines of text vertically you need to display. Decide the maximum height of the letters you want each row to use.
Add at least 2” between rows, and 1.25” top and bottom. If you are going to use both upper and lower case letters allow additional space for the descending letters also. The amount of space varies by letter size and style. Will you want a lighted border around your message?
The cumulative total is how tall the minimum display height of your sign must be, in inches.
But, can the display clearly display your smallest letters? For a standard block letter style the smallest letter a 20mm sign can clearly display is a 6.3" tall lower-case character. A 16mm sign can display 5.1" minimum-height characters.
It is possible to go smaller, but it may require some experimentation with letter styles and spacing. Smaller letters probably require a tighter pitched sign.
If you plan on using some lower-case letters recognize that their shorter height is your shortest letter.
To determine minimum letter height for all sign pitches, multiply the pitch of a display you are considering, in millimeters (say 20), or by the LED spacing in a Balanced Array™ times 2, by 0.315. This tells you the smallest letter the display you are considering can reliably display.
Next, decide on the longest message you need to display. Count both the letters and spaces, and include space both before and after the message. Multiply by 0.3145. Now multiply by the pitch of a display you are considering, in millimeters (say 20), or by the LED spacing in a Balanced Array™ times 2. The answer is how long the sign display must be in inches to display the message adequately in most letter styles. Realize that some letter styles would require an even longer display, but this is a good average.
You now know if the size and pitch of the sign you are considering will meet your needs.
The minimum viewing distance is the point at which the
display loses its graininess. This can vary
depending on the message being displayed.
The maximum viewing distance is the point at which the
smallest character which will be generated on the display
becomes unreadable. A potential solution is to
generate larger characters, but this may increase the
minimum viewing distance.
Desired Minimum Character Size
The length of time letters are readable when moving towards them.
These times are only achievable when viewing signs made with LEDs with wide viewing angles.
Many signs reading times are much shorter for the same sized letter.
Prepared by Signs Manufacturing Corporation
More than any other part of the sign the operating software determines the usability of the system. Sunburst Displays™ proprietary operating software contains many virtually unique features into one package:
Encryption so that no one else can operate the sign.
The programming computer's screen displays exactly what the sign will look like.
The software allows enlargement after images or text are uploaded.
Displays can be programmed using Power-Point, Corel, Photoshop, or any graphics software you are familiar with. So you already know how to program the sign.
Pixel Text can be directly entered.
Add multiple images at once, speeding set-up time.
The computer communicates with the sign via Wi-Fi, and only needs to be "on" when changing the program. The sign runs on its own internal processor. You can create a program at home, and download it to your sign when you get to your business, if you desire.
One click updates the sign.
"Virtual pixel" creation to allow the advantages of a "Balanced Array™" as explained above.
With our control software and our internal processor, these are very fast signs. This allows for the use of Text, Graphics, Animation, Slideshow, Video, Scheduling, Time, Temperature, and Brightness Control listed separately below.
Text, Graphics, or Both
Some competitive units only display text, some must display
text as a graphic (drawing), some can display both
text and graphics. Some competitors can only display "stick" letters (one line.)
Sunburst Displays™ proprietary software can display text and graphics, and we can vary the font (letter style) and the thickness of the letters.
Many varied letter-styles (fonts) are pre-programmed
in all our units.
All our units can also automatically place text over
On our monochrome units (one color) text and graphics can be displayed
in 1 or 256 shades of the one color. Full-color units
display 281,000,000,000,000 separate shades.
Animated Text and Graphics
All Sunburst Displays™ software can display fixed messages or graphics (drawings) or “scroll” messages or graphics (drawings) and include F/X features. We also show a display such as a cartoon with character movement, for instance.
Monochrome displays convert colors to shades of either Red or Amber (Yellow.)
All Sunburst Displays™ programming can display pre-programmed messages and pictures in a slideshow format, much like a screensaver slideshow showing multiple messages or images.
Video - Prerecorded Clips
All Sunburst Displays™ proprietary software can display videos of varying random lengths.
Live Video or TV
Live video or television feeds are available options.
Schedule various messages, graphics or videos to automatically run at various times of day or night with Sunburst Displays™ software.
Double-Sided Display Programming Options
Most competitive units display the same message or animation on both sides of a double-sided display.
However some competitive units can only be programmed totally independent of each other. There displays will not synchronize, so they take twice as long to program.
Sunburst Displays™ standard is a synchronized display, with independent programming an inexpensive option.
Display Size and Appearance
Some displays have "retainer", or a picture frame around the display.
Some displays are "bleed", or the matrix goes to the edge of the face.
A bleed face gives more display space in the square footage allowed if a city has a restrictive sign ordinance.
Glare Shields (Louvers)
Glare shields, also called louvers, prevent a display’s LEDs from appearing to be lighted, by sunlight, making your message unreadable.
Sunburst Displays™ curved glare shields are individually molded into the actual face, not bolted on, to individually shade each LED.
These features guarantee that our shields are effective and positioned properly. They also allow our shields to be as small as possible to eliminate their interference with viewing our displays from below or above.
This is a very common problem with competitive displays with shields that are straight, or continuous. Theirs are less effective and must be much larger, limiting the viewing angles of their signs.
Automatic Brightness Control
Sunburst Displays™ and other quality displays automatically adjust their brightness to the current lighting conditions.
A good LED display that is bright enough to draw attention during the day is too bright at night without Automatic Brightness Control. It's like staring into a flashlight; nothing is readable!
LED’s are affected by
voltage. For instance, an LED will burn nearly
100% brighter if you double the power feeding it.
The LED will last about 1/6 as long, however, making this
alternative quite expensive in total cost.
LED's dim as they age. At some point (subjective) they will need to be replaced because they are too dim. Feeding them less voltage extends their useful life.
Sunburst Displays' engineering goal was to balance brightness and longevity.
If only brightness is important a monochrome display that does not include a grayscale feature, or automatic brightness adjustment, will be the brightest, at least initially, because all LED's will always be fully-powered. The LED's can also be more closely packed because only one color of LED is used; room does not have to be dedicated to other-colored (RGB) LED's.
Colors in motion, though dimmer than monochrome, have proven to be a better attention-getter, and the displays last longer.
A thermometer installs on the sign cabinet and plugs
into the sign computer in systems set-up for this
Computer Link Types
Optical Fiber. Run underground from the
sign to the controlling computer, usually inside the
building. This fiber must be run in separate
conduit, but it can be buried in the same trench as
the electrical supply.
Phone Control. The unit can have a cell
phone number and a modem. Simply call the sign
from the controlling computer and tells it what to do.
The internal memory of the electronic message center
repeats these instructions until they are changed.
RF Wireless Modem Communications. An
antenna is placed on the sign, and on the building,
which is hooked to the controlling computer.
Wi-Fi Modem. Uses a wireless modem connection in the computer, and in the sign cabinet, to communicate.
It is possible to have one computer control multiple
of our electronic message centers (all Long John
Silver’s are, for example.)
Besides the computer that is used to program the sign there is a processor or a computer inside the sign in most systems.
The poorly engineered signs are programmed and controlled by a single computer that is hard-wired to the sign and must be left "on" at all times. Or, in some cheap signs a second "personal computer" is actually installed inside the sign.
The problem with either of these systems is that the sign is running on "Windows" using a CD or hard-drive and is additionally subject to all the viruses, freezes, lock-ups and reboot problems that a personal computer faces. (As a simple example of the problems faced, who climbs the pole of a free-standing pole sign to reboot the computer after a power outage or computer lock-up? Service call.)
Plus, with all the moving parts in hard drives, disk drives, and other humidity and temperature sensitive components, a PC is a poor way to run a sign from inside the sign. They fail often enough when they are used in the controlled environment of a building.
Tremendous cooling is required when there is an "Intel Inside" but many of these poorly engineered units don't even have cooling fans for the LED displays, much less the computer's processor chip.
In the worst of all signs, the software to program the computer inside the sign is not even in the sign owner's possession. It is not on the programming computer, it is "on the cloud." The sign’s computer must have high-speed internet access.
What if the sign manufacturer does not own the software, he uses a third-party system, and they notify you that in order to keep your sign operating you will now have to pay them $2,000 per month to continue access to the programming software. This happens all the time with other "free" software. Or, he controls the software "on the cloud" but goes out of business so your sign cannot be programmed by anyone.
We don't have a "computer" in our signs. The processor in our signs is a "mother-board" with a non-volatile memory (no heat-sensitive processor chip) and its sole purpose is to store and control using the commands you send it from the programming computer we furnish Free with the sign. (No rebooting!)
The programming software is on the computer we give you, and we also give you a back-up copy.
This vastly superior system also uses less energy.
Heat is the enemy of LED’s. Sunburst Displays™ electronic message centers have multiple inflow and outflow ventilation fans. Additionally, every heat-producing component has its own internal cooling fan. Larger units incorporate air conditioners into their design. Excessive heat can shorten LED life by up to 80%.
In poorly engineered signs with little (passive) or no cooling, decreasing the pitch, increasing the size of pixels, or over-driving LED’s with higher-than-required voltage to increase their brightness, increases heat, shortening the life of the unit.
Some units vent out the front of the sign, some out their sides, and some out the rear. This affects how each unit can be installed. For instance, a unit that vents out its sides cannot be covered with brick.
Some message centers are serviced by removing their face, some by removing their back, some by removing a frame around the face and sides of the sign. This also affects how each unit can be installed.
Solarbrite™ Light Emitting Diode (LED)
A light-emitting diode (LED) is a semiconductor device that emits incoherent monochromatic light when electrically biased in the forward direction. This effect is a form of electroluminescence. The color depends on the semiconducting material used, and can be near-ultraviolet, visible or infrared.
A LED is a special type of semiconductor diode. Like a normal diode, it consists of a chip of semiconducting material impregnated, or doped, with impurities to create a structure called a pn junction. Charge-carriers (electrons and holes) are created by an electric current passing through the junction, and release energy in the form of photons as they recombine. The wavelength of the light, and therefore its color, depends on the band gap energy of the materials forming the pn junction. A normal diode, typically made of silicon or germanium, emits invisible far-infrared light, but the materials used for a LED have band gap energies corresponding to near-infrared, visible or near-ultraviolet light.
Unlike incandescent bulbs, which can operate with either AC or DC, LED's require a DC supply of the correct polarity. When the voltage across the pn junction is in the correct direction, a significant current flows and the device is said to be forward biased. The voltage across the LED in this case is fixed for a given LED and is proportional to the energy of the emitted photons. If the voltage is of the wrong polarity, the device is said to be reverse biased, very little current flows, and no light is emitted.
Conventional LED's are made of inorganic minerals such as:
aluminum gallium arsenide (AlGaAs) - red and infrared
gallium arsenide/phosphate (GaAsP) - red, orange and yellow
gallium nitride (GaN) - green
gallium phosphate (GaP) - green
zinc selenide (ZnSe) - blue
indium gallium nitride (InGaN) - blue
silicon carbide (SiC) - blue
diamond (C) - ultraviolet
LED development began with infrared and red devices, and technological advances have made possible the production of devices with ever shorter wavelengths.
Blue LED's became available in the late 1990s. They can be added to existing red and green LED's to produce white light. Most "white" LED's in production today use a blue LED chip covered by a scintillate coating made of Zinc solenoid (ZnSe). The LED chip emits blue light, part of which is converted to yellow by the ZnSe. This mixture of blue and yellow light creates the impression of white - hence the bluish or yellowish tint that these diodes usually exhibit.
The most recent innovation in LED technology is a device that can emit ultraviolet light. When ultraviolet light illuminates certain materials, these materials will fluoresce or give off visible light. White light LED's have been produced by building ultraviolet elements inside material that fluoresces to produce white light.
The semiconducting chip is encased in a solid plastic lens, which is much tougher than the glass envelope of a traditional light bulb or tube. The plastic may be colored, but this is only for cosmetic reasons and does not affect the color of the light emitted.
Most typical LED's are designed to operate with no more than 30-60 millewatts of electrical power. In 2002, 5 watt LED's became available with efficiencies of 18-22 lumens per watt.
SMD (Surface Mounted Device) LED's have been created that combine RGB (Red, Green, Blue - which can make White) color sources in one LED. This allows the display matrix, pitch, to be much closer. They are very expensive, but more importantly do not have the nits (candela per square meter) for outdoor use. Manufacturers currently brag that they can produce 4-6,000 nits. We are patiently watching this development.
Signs Manufacturing's Sunburst Displays™
Solarbrite™ LED’s are 8,000 to 13,000 nits, depending on color. (The brightness of Solarbrite™ LED's can be turned down if they are too bright.)
Many companies manufacture

Incandescent (household) lamps begin disappearing in 2012, starting with the 100 watt lamp, and will be mostly gone by 2014.
The Government has mandated that all these lamps, with 22 exceptions, must begin being at least 25% more energy efficient starting in 2014, 70% more efficient by 2020.
"Sign Service" lamps are exempt, but whether or not lamp manufacturers will recognize a big enough market to continue to make just them is problematic.
The Value of “Listed" Signs
Virtually ALL cities, as well as the State of Texas, adopt the National Electric Code as law.
The National Electric Code (NEC) requires that for electrical, structural, and installation safety all electrical signs be "Listed" (tested and labelled with an appropriate Listing Mark.)
Certification (testing and labelling) organizations acceptable in the USA to test to the multitude of Standards signs are required to meet are determined by OSHA.
For you the Listing Mark is insurance. It means that the sign has been tested to insure that it is structurally and electrically safe, and will be installed properly. You benefit from the knowledge that it is not solely us telling you that our signs are safe, this is what the testing laboratories and the US Government says also.
Underwriter's Laboratory (“UL” Listing Mark) and Intertek (“ETL” Listing Mark – originally Edison Testing Laboratory founded by Thomas Edison) are the premier certification organizations and 80% of all things electrical are tested by them.
If the sign you are purchasing does not have a ETL or UL Listing Mark label the sign is probably not legal to install, anywhere in Texas. There are a few local city ordinance exceptions.
Intertek is over twice the size of UL, and has a greater global presence. UL is the largest in the USA. We have both companies test and apply Listing Marks to various signs.
We are the third oldest ETL Listed sign company in Texas. (One of the two older companies makes lighted scoreboards, the other makes lighted office door signs.)
There are many sign companies that pretend to be Listed, but are not!
Incidentally, ISO (International Organization of Standardization) Standards, such as ISO 2001, are NOT electrical Listings (similar to a UL or ETL Listing) that allow a sign to be installed in Texas. That said, components in our electronic signs also meet ISO 2001, ISO 9001, ISO 14001 and RoHS standards.
Underwriter’s Laboratory and Intertek do NOT judge the appearance, appeal, or the longevity of a product. This is why our many years of experience serving international, national, regional and local customers, and our investment so that we can apply the knowledge we’ve gained, will give you a superior product which will impress your customers for years to come.
The Electrical Advantage of a “Listed" Sign
Listed Signs Save You Money.
Sunburst Displays Video Displays and Electronic Message Centers, because they are Listed, are approved to operate with approximately 40% of the power supply requirements of unlisted signs.
This is a huge savings in installation costs, as only 1/3 of the comparable electrical service needs to be provided.
And since the National Electrical Code limits the branch circuits serving signs to 20 amps maximum, this equates to many fewer circuits.
For safety, an untested sign (not Listed) must be supplied with enough electricity to meet the total “continuous” needs of each internal components rating. (Each components rating x 125%)
A Listed sign has been tested as a whole, and the amount of energy actually used has been determined. The sign is approved for use when supplied with this amount of electricity, regardless of the ratings of the individual components.
This is always much less than the rating of each internal component taken individually, so the cost of installing electricity to the sign will be significantly less.
120 volt single phase service is normally required
because these Listed displays do not consume a great deal of
energy, but some units require 240 volt 1 phase.
Remember, however, that other parts of the sign will
have electrical requirements also.
Radio Frequency (RF) interference can cause a sign to interfere with radios, cell phones, radar, automatic door openers, etc.
Although not required, Signs Manufacturing had our electronic signs tested for Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI).
This assures you of an even-more-trouble-free sign when you purchase from Signs Manufacturing Corporation.
This varies by the message displayed, and how long the electronic message center is on.
That said it is uncommon for ANY electronic (LED) message center to use over $1.00 in electricity in a day.
Some electronic message center manufacturers, more
interested in the sale than the needs of the customer,
overdrive their LED’s to make them brighter (usually
because they are using inferior LED’s.)
Besides shortening the lifetime of the display to 1/6
of a properly manufactured display it wastes energy.
Sunburst Displays™ does none of this!
We do provide internal overvoltage, low voltage, spike and brownout protection for the sign. Many manufacturers do not.
The system should have easy to use control software
with built in features such as scrolling and blinking
messages and a time and temperature display. It
should also allow you to preview both individual
messages and your whole display queue without forcing
you to show the world your half-finished ads by
running them on the display. The message should
be able to be changed from inside your business, or
the system should be configured so that “headquarters”
can change the message at each store.
Learning how to program an electronic message center
is not hard.
Most good manufacturers have teaching CD’s in addition
to Technical Assistance.
Many have telephone training included as part of their
Signs Manufacturing is particularly adept at these
systems, and helps our customers until they no longer
Then we come back when they find they were premature.
Product and Technical Support
Most important in an investment of this size is product support.
The electronic message center manufacturer must be large and dedicated enough that they will continue to support their products with parts.
Technical support must be easily available and there must be no limit to your access to it.
Even after you have become an expert, and years later, you might have difficulty programming a new-look message.
Make certain your electronic message center manufacturer and installer will be there to help you 24 hours a day.
Minimum Computer Requirements
Most up-to-date computers, purchased within 2 years,
have enough memory to create control programs.
It is usually NOT necessary to buy a
separate/additional computer to control an electronic
FREE Programming Computer with Sunburst Displays™
Each Sunburst Displays™ electronic message center comes with a "free" pre-programmed laptop computer ready to remotely program your new electronic message center.
Tutorials are a part of the computer’s pre-programming.
Full-color displays can also be programmed using Power-Point, Corel, Photoshop, or any graphics software you are familiar with. So you already know how to program the sign!
The computer communicates via Wi-Fi, so you probably already know how to work it, and it only needs to be "on" when you are changing the program. The sign runs on its own internal processor.
You can create a program at home, and download it to your sign when you get to your business, if you desire.
Proprietary encryption in both the sign and the programming computer software make the sign impossible to use by anyone else.
SolarGuard™ Protection for Sunburst Displays™
Our plastic faces that hold the LEDs, and Glare Shields, have internal UV protection. But
your sign needs to look nearly as good 10 to 15 years from
now as it looks the day it is installed.
longevity and appearance of plastic face materials are extended when they are coated with
SolarGuard™, a special, clear, high-gloss,
mar-resistant topcoat which protects plastics from
ultraviolet light and ozone so that they last longer, just
like your eyeglasses have UV coatings to protect the
Signs Manufacturing is an authorized
Signs Manufacturing adds
SolarGuard™ protection to every plastic sign face component.
Does SolarGuard™ Protection
Work? The face on the right was made of
“generic” red acrylic and black trim-cap. The left
half was coated with SolarGuard™ and the face was left
outside for ONLY 7 years; your sign will be out there much
(This product does not come from the traditional sign industry. Few sign manufacturers know about it, or where to get it.)

Self-Cleaning Faces for Sunburst Displays™
Signs Manufacturing adds Lumabrite™
coatings to every plastic-faced sign.
Lumabrite™ reduces maintenance
because of built-in self-cleaning properties.
This products inspiration was the optical plastic lens industry.
Our people are factory-trained in the
application of Lumabrite™.
Construction Details for Sunburst Displays™
Free-standing signs are engineered to survive a 140 mph wind.
All face-plates, the part of the sign that the display's external LED boards are mounted to, are CAD/CNC (Computer Aided Design/Computer Numerical Controlled) routed from solid aluminum plate, to prevent rusting and increase heat dissipation.
An extensive lattice-formed 3-dimensional aluminum frame is welded to the face-plate to insure rigidity and further aid in heat dissipation.
Aluminum is also used for all exterior surfaces of the sign cabinet, again to prevent future rusting.
Almost all Chinese-manufactured signs, among others, have steel cabinets and face-plates.
With some manufacturers, incredibly, the face-plate is merely many individual pieces bolted together. Hardly engineered to withstand 140 mph tornado winds.
Water is the enemy of electronic message centers. Sunburst Displays developed a unique cabinet design that channels water and ice away from vital internal electrical components.
The face boards, containing the LEDs, are gasketed and hermetically sealed to prevent moisture from entering the sign through the faces.
Some manufacturers use 12" by 12", or larger, face boards. Easier to manufacture the sign, but this removes at least half the structure in the face-plates these LED boards are fastened to, making the entire sign much more susceptible to wind, especially hurricane and tornado, damage. We manufacture 6" by 12" face boards.
The interior of the sign incorporates a welded structural-steel frame, necessary for the strength to withstand 140 mph winds. All other interior metal is aluminum also.
All fasteners are galvanized or non-corrosive; no rust. In a Sunburst Display 8 screws fasten each 6" x 12" face board to the sign frame. That's 32 screws in a 12" x 12" area compared to the 4 plastic clips most manufacturers use.
Most Chinese displays are painted with questionable paints. (Remember when the Chinese were caught painting Mattel kid's toys with lead paint?) We even add self-cleaning properties.
Revolutionary Ceramic Vacuum Microsphere Shield
During a Texas summer, your Texas electronic message center can experience daily internal heat levels of over 200* F, enough to seriously damage it, shorten its life, and cause you expensive repairs.
High heat is very hard on electronics and LED’s, and shortens both their lives.
NASA, with the Space Shuttle program, has proven the value of insulating ceramic vacuum microspheres as a thermal barrier to both heat and cold.
While not as debilitating as temperatures experienced by the Shuttles, we commonly experience temperatures well over 200º inside Texas signs. Water boils at 212º at sea level.
Signs Manufacturing builds a better sign. We cover the metal exterior of each Sunburst LED Display™ with the same ceramic vacuum microsphere barrier developed by NASA.
We have documented 30% internal heat differences, 60º cooler at 200º, accompanied by an 80% increase in heat dissipation when compared to identical signs without our ceramic shield.
NASA confirms that 90% of solar infrared and 85% of ultraviolet rays are reflected back into the atmosphere by this revolutionary product.
Visually the only difference is the very slightly textured appearance of our ceramic barrier when compared to uncoated metal; a small price to pay, especially since you will never notice the difference. We still use the same wonderful paints with the same excellent results.
Impact protection from hail, asteroids, and other objects is vastly improved also.
Made in Texas, for Texans, by Us.™
By using 6" x 12" face boards we also gain the versatility of manufacturing signs with twice the available height options.

Quality Certified Signs™ Trained Technicians
All Sunburst Displays™ shop, installation and service personnel are QualityCertifiedSigns™ trained technicians.
www.QualityCertifiedSigns.org for listing details.
Sunburst Displays™ employs Certified Welders; horizontal, vertical, and overhead.
We are virtually the only sign company in the Dallas/Fort Worth Metroplex employing certified welders.
The quality suppliers get their product to us in
4-8 weeks. Our manufacturing cycle is usually slightly shorter than this.
Since most electronic message centers are built into
or installed as part of additional signs we need
time to fit the parts together.
Sunburst Displays™ warranty is the STRONGEST TOTAL WARRANTY for Digital LED Video Displays and Electronic Message Centers in the industry!
If ANY part of a Sunburst Displays™ video display or electronic message center fails in the first three years of service, if properly supplied with power, Sunburst Displays™ will provide BOTH parts and service FREE OF CHARGE through Signs Manufacturing Corporation.
Even stronger, this Initial Warranty is extendable to six years.
Plus, Sunburst Displays™ warrants their signs with a LIFETIME* WARRANTY, again through Signs Manufacturing Corporation, that reduces both normal labor rates for service, and parts costs, 20% forever.
Sunburst Displays™ Lifetime* Warranty is transferable at no additional cost!
Virtually no other LED Video Display or Digital Electronic Message Center manufacturer IN THE WORLD provides a warranty on ANY labor, much less a transferrable warranty.
Additionally, after the Initial Warranty period, Sunburst Displays™ will provide free replacement parts for any previously replaced part that fails within one year of installation.
Other manufacturers whose products we install and service have varying new-sign parts-only warranties that average 3 years.
($70,000) electronic-message-centers were nightmares. Even
though they were only 2 years old the manufacturer
refused to service them. Your new signs, and
your service, have been exceptional."

"...I had to hound Vital ***** (a sign broker) for weeks and weeks, then I had to call ******** (the manufacturer) to finally get a hold of Vital *****. I thought Vital ***** was taking my deposit money and running. When he asked for the second deposit I was kind of hesitant based on my experience with him. I did some research on Vital ***** and there were judgments in Dallas County, civil judgments for Vital ***** taking money and not putting up a sign! But the manufacturer said I had to deal with him, and he already had a great deal of my money.
The installation company he subcontracted with, City *****, finally did show up and after giving them another $30,000 the sign was installed but City ***** didn't pay Vital *****, I guess, his "fair cut" of it.
Vital ***** was initially mad at City ***** and then he was mad at me, so he came and took the controller out of the sign so now it doesn't even work! I tried to go back to ******** (the manufacturer), and gave them all of the documentation and they said it's between me and Vital *****, they won't do anything about it. I'm never dealing any way but directly with a manufacturer again!"

"...the sign will be dismantled. ...not knowing when and how to get parts was a major factor..."
Cathy Clarke, Johnson Elementary School, Southlake. They are throwing away their $40,000 six-month old sign because they can't get parts to repair it (company out of business.)
“We bought an Adapxxxx Displays LED Message Center. I'll be glad when the warranty has expired and I can justify a new Sunburst LED Display. So far the labor installing our "free" repair parts is over $6,000.”

Controlling Message Center and Video Display Cost
Electronic Message Centers and Video Displays cost a lot of money, but they achieve tremendous results.
To keep from spending more money than necessary, consider the design of your sign and the results you want to achieve.
Rather than purchase a larger, blank, rectangular message center and display your name and all other information on it, consider incorporating signage that constantly displays the messages you want to constantly display. It will cost less, and look better!
Because we manufacture and install all types of signage, not just electronic message centers, we can design, build, and install the most cost efficient and effective signage for you
(see our "Design & Marketing" page!)
