This specification applies to the 55 inch Color TFT-LCD Module T546QB01 V0. This LCD module has a TFT active
matrix type liquid crystal 3,840*2,160 panel pixels, and diagonal size of 55 inch. This module supports 3,840*2,160
mode. Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes. Gray
scale or the brightness of the sub-pixel color is determined with a 10-bit gray scale signal for each dot.
The T546QB01 V0 has been designed to apply the 10-bit , 16ch V by one interface method. It is intended to support
displays where high brightness, wide viewing angle, high color saturation, and high color depth are very important. Also,
3D function is also embedded into front glass.

5. The relative humidity must not exceed 80% non-condensing at temperatures of 40℃ or less. At temperatures
greater than 40℃, the wet bulb temperature must not exceed 39℃. When operate at low temperatures, the
brightness of LED will drop and the life time of LED will be reduced.
6. The lifetime (MTTF) is defined as the time which luminance of LED is 50% compared to its original value.
