Active Screen Size

The LP140WH2 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (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(768 vertical by 1366 horizontal 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 LP140WH2 has been designed to apply the interface method that enables low power, high speed, low

EMI.

The LP140WH2 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

LP140WH2 characteristics provide an excellent flat display for office automation products such as Notebook

PC.
