Product Specification
1. General Description
The LC840EQD is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
backl i ght sy st em . T he m at rix em pl oys a-Si T hi n F i lm T ransi st o r as t he act iv e el em ent .
It is a transmissive display type which is operating in the normally black mode. It has a 84.04 inch diagonally
measured active display area with QWUXGA resolution (2160 vertical by 3840 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 16 Lane V by One interface.
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.
