LP140WH4
Liquid Crystal Display
Product Specification
1. General Description
The LP140WH4 is a Color Active Matrix Liquid Crystal Display with 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 white mode. This TFT-LCD has 14.0 inches diagonally measured active display area with HD
resolution (1366 horizontal by 768 vertical 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 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 LP140WH4 has been designed to apply the interface method that enables low power, high
speed, low EMI. The LP140WH4 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-
pixels, the LP140WH4 characteristics provide an excellent flat display for office automation products such
as Notebook PC.
