Just like its name implies, a screen LED display is a kind of display which uses LEDs for illumination. It has technological applications ranging from small digital photo frames to massive public displays in stadiums. The quality of a screen LED display is determined by pixel pitch, brightness, contrast ratio, and color accuracy. Finer pixel pitch increases the resolution of the display. Smaller pixel pitch is advantageous for close range viewing like in outdoor billboards. The ability to maintain high brightness level is critical for display screens that are used in the sunlit outdoors. Other factors include sharp brightness, contrast, and color accuracy which enhance and maintain the overall experience. Today, companies from different fields such as printing, advertising, entertainment, and information technology are now investing in Screen LED Displays.
