LM185WH2
Liquid Crystal Display
Product Specification

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.
