Product Specification
1. General Description
The LC550EUH is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
b a ckl i g ht sy st em . T he m at ri x em pl oys a-Si T hi n F ilm T ransi st or 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 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 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.
