Product Specification
1. General Description
The LD420EUP is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
b ac k l i g ht s ys t em . T he m a t r i x em p l o ys a - S i T h i n F i lm T r an s is t or a s t he a c t i v e e l em en t .
It is a transmissive display type which is operating in the normally black mode. It has a 42.02 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.
