LD550EUD
Product Specification
1. General Description
The LD550EUD is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
Local Block backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive display type which is operating in the normally black mode. It has a 54.64 inch diagonally
measured active display area with WUXGA resolution (1080 vertical by 1920 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 1.06Bilion colors.
It has been designed to apply the 10-bit 4-port LVDS interface.
It is intended to support Public Display where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.
