This specification applies to the 42.0 inch Color TFT-LCD Module T420HW07 V7. This LCD module has a TFT
active matrix type liquid crystal panel 1,920x1,080 pixels, and diagonal size of 42.0 inch. This module supports
1,920x1080 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 8-bit gray scale signal for each dot.
The T420HW07 V7 has been designed to apply the 8-bit 4 channel LVDS interface method. It is intended to
support displays where high brightness, wide viewing angle, high color saturation, and high color depth are very
important.
