1. General Description
The LP156WF4 is a ColorActive Matrix Liquid Crystal Displaywith an integral LED backlight system. The
matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive type display operating in
the normally black mode. This TFT-LCD has 15.6 inches diagonally measured active display area with FHD
resolution (1920 horizontal by 1080 vertical pixel array). Each pixel is divided into Red, Green and Blue subpixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is
determined with a 6-bit gray scale signal for each dot, thus, presenting a palette of more than 262,144
colors. The LP156WF4 has been designed to apply the interface method that enables low power, high
speed, low EMI. The LP156WF4 is intended to support applications where thin thickness, low power are
critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-
