LED Signage
Light emitting diodes (LED) are special diodes that emit light when illuminated by the movement of electrons in the semi-conductor chips.
Advantages of LED Lighting
LED technology is quickly becoming tomorrow’s primary light source and have several advantages over conventional light sources:
LEDs for sign illumination are rated for continual use for up to 100,000 hours.
LEDs radiate a “cold light”, meaning they generate very little heat compared with other lighting technologies. This also means less wasted energy.
LEDs are energy efficient meaning they consume less energy to produce brighter illuminated displays that creates much greater readability and flexibility of use than traditional signs and billboards.
LEDs are manufactured in a full range of colors and with appropriate mixing schemes can generate billions of colors.

The Optec Advantage - Patented Hybrid Pixel
Higher Brightness / Enhanced Contrast
Wider Viewing Angle
Individually Replaceable
Inherent Protection
Optec’s Hybrid Pixel
Together with Optec’s advanced controller system, we can control brightness/color shadings down to each LED lamp level vs.competitors’ individual pixel shading.
The result is better color mix, contrast, higher virtual resolution and longer LED life since we can turn off individual LED lamps when not needed. Optec uses only the best quality LEDs to manufacture its displays. In fact, Optec is one of the biggest customers of Nichia, who is one of the leading LED manufacturers in the world. Optec also provides more LED diodes per pixel than other competitors. Together with the Hybrid Technology, Optec LED displays simply provide the best brightness, viewing angle, and color in the industry.

Optec’s Hybrid Pixel Louvers
With Optec’s unique hybrid pixel technology, each pixel is hot swappable, reducing time and cost to service a display. Hybrid technology also provides a flexible platform to create custom shape LED displays such as curved face displays. With each pixel sticking out instead of attached to the surface, Hybrid pixels have the widest viewing angle and best heat ventilation in the world. Instead of 1 louver per pixel, each LED lamp on a Hybrid pixel has its own lamp louver which provides highly focused LED light out put for superior color contrast, brightness and maximum horizontal viewing angle. Inside each pixel, there is an individual circuit controlling each LED lamp.
Pixel vs True Pixel
Some LED display manufacturers use “virtual pixel” technology. They claim that “virtual pixel” doubles the actual resolution of screen, i.e., a screen with a physical (true) resolution of 320×240 pixels in reality is expressed as the “virtual” resolution of 640×480. In a “Virtual Pixel” Display in an attempt to smooth out digital image, each pixel of the image corresponds not to an actual module pixel but to a light/data source, that is part of the group of pixels that form the “Virtual pixel”. By this mode of pixel sharing one pixel contains the “Virtual group”* of pixels image information. *(The 2 or 4 pixels that are combined to form the “Virtual” effect). Virtual pixels are also known as “pixel sharing” or “dynamic pixels”. Some claim that with “virtual pixels” the displayed image has twice the resolution as the “physical” resolution. This is not true, since one module pixel cannot memorize or hold and display the majority of information from the initial pixel. The majority of the original information vanishes. This results in distortion of important details and other elements such as colors that are part of the initial image.
In the actual, physical or true pixel technology, the image is displayed on a display in as each pixel of the original image corresponds to pixel on a screen. It takes the actual color in a pixel as it is balanced in brightness and contrast and no additional corrections are required. Optec Digital Billboards only uses true pixel technology.

Pitch (Resolution)
cluster of many diodes running off the same Resolution, or the total number of pixels in a display, is a very important factor that affects the performance of the sign. More resolution means more LED diodes and more circuits, which usually means better picture quality. Pitch is the distance (usually in millimeters) between pixels. Pitch is always measured from the center of one pixel to the center of an adjacent pixel. The smaller the pitch number, the higher the resolution quality. Larger the pitch numbers indicate a lower resolution. A pixel can be one single diode, or a pixel can be a circuit.
LED density of a display is the total number of LED diodes in one square meter. It is calculated by mLED diode density and pixel pitch are the two most critical factors to determine the quality of resolution and display brightnessultiplying the number of pixels per square meter by the number of LED diodes per pixel.
Optec Digital Billboards’s LED display systems have always featured more LEDs per pixel than other LED display manufacturers. Our higher LED diode density provides significantly higher brightness and longer display life since each individual diode can be driven at lower levels of intensity, reserving capacity to extend the display’s life - without sacrificing proper viewing brightness.
3 LED’s vs 5 LED’s
20 mm video display with 3 LED’s per pixel
Matrix = 48 x 128
Total diodes 18,432
20 mm video display with 5 LED’s per pixel
Matrix = 48 x 96
Total diodes 23,041
Viewing Distance and Speed
The distance between your sign and its viewers is the number one factor in determining the type of LED display you will need. Longer distances require less resolution and shorter distances require higher resolutions. In addition, if you are traveling at 55 MPH on a freeway, and the sign is 600 feet away at a truck stop, the text letters must be at least 20 inches tall to be legible. Likewise, if you are standing 60 feet away from a street level sign, the letters need only be two inches tall to be legible.
The rule of thumb is that you need 1 inch for every 30 feet of viewing distance.
Your business image. A good display tells who you are.
LED displays are an on-premise advertising medium, and intended to direct nearby traffic flows into your business location. Once you install an LED display outside your business location, it becomes part of your business image. LED displays add a high tech, modern feeling to your business location and help influence impulse stops’ from passing motorists to do business with the store beneath the sign.
