General Features
1. General Description
The LC550DQJ is a Color Active Matrix Liquid Crystal Display with an integral the Source PCB and Gate
implanted on Panel (GIP). The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally black mode. It has a 54.64 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 arranged 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 1.07B colors.
It has been designed to apply the 10-bit 6 Lane EPI 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.
