LP116WH1

Liquid Crystal Display

Product Specification

1. General Description

The LP116WH1 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 11.6 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 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 LP116WH1 has been designed to apply the interface method that enables low power, high speed, low

EMI.

The LP116WH1 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
LP116WH1 characteristics provide an excellent flat display for office automation products such as Notebook
PC.
