LM185WH2

Liquid Crystal Display

Ver. 1.0

JUN., 21, 2010

1. General description

LM185WH2-TLA1 is a Color Active Matrix Liquid Crystal Display with a Light Emitting Diode

( White LED) backlight system without LED Driver. The matrix employs a-Si Thin Film Transistor

as the active element. It is a transmissive type display operating in the normally white mode.

It has a 18.5 inch 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 8-bit gray scale signal for each dot, thus, presenting a palette of more than

16,7M colors with Advanced-FRC(Frame Rate Control). It has been designed to apply the

interface method that enables low power, high speed, low EMI. FPD Link or compatible must be

used as a LVDS chip. It is intended to support applications where thin thickness, wide viewing

angle, low power are critical factors and graphic displays are important. In combination with the

vertical arrangement of the sub-pixels, the LM185WH2-TLA1 characteristics provide an excellent

flat panel display for office automation products such as monitors.
