Liquid Crystal Display
Product Specification
1. General description
LM185WH2-TLE1 is a Color Active Matrix Liquid Crystal Display with a Light Emitting Diode(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. 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(Low Voltage Differential Signaling) 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-TLE1
characteristics provide an excellent flat panel display for office automation products such as
monitors.
