Product Specification
LP121WX4
Liquid Crystal Display
1. General Description
The LP121WX4 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 12.1 inches diagonally measured active display area with
WXGA resolution (1280 horizontal by 800 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 LP121WX4 has been designed to apply the interface method that enables low power,
high speed, low EMI. The LP121WX4 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 LP121WX4 characteristics provide an excellent flat display for office automation products
such as Notebook PC.
