LP141WX5 Liquid Crystal Display
1. General Description
The LP141WX5 is a Color Active Matrix Liquid Crystal Display with an integral 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 14.1 inches diagonally measured active display area with WXGA resolution(800 vertical by 1280 horizontal 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 LP141WX5 has been designed to apply the interface method that enables low power, high speed, low EMI. The LP141WX5 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 LP141WX5 characteristics provide an excellent flat display for office automation products such as Notebook PC.
