1. General Description

General Features

The LP140WF1 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 black mode. This TFT-LCD has 14.0 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 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 LP140WF1 has been designed to apply the interface method that enables low power, high

speed, low EMI. The LP140WF1 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 LP140WF1 characteristics provide an excellent flat display for office automation products such as

Notebook PC.
