LED diode density and pixel pitch are the two most critical factors to determine the quality of resolution and brightness of digital displays. The LED density of an electronic display is the total number of LED diodes in one square meter. It is calculated by multiplying 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.
