Product Specification
1. General Description
The LC420EUS is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
bac k light s ys tem . T he m atr ix em plo ys a- S i T hin F i lm T r ans is tor as the ac ti ve e lem ent .
It is a transmissive type display operating in the normally black mode. It has a 42.02 inch diagonally measured
active display area with W UXGA resolution (1080 vertical by 1920 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 16.7M(true) colors.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.
