LM181E1-J3MN
Liquid Crystal Display
Product Specification
1. General Description
The LM181E1-J3MN is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode
Fluorescent Lamp(CCFL) back light system. The matrix employs a-Si Thin Film Transistor as the active
element. It is a transmissive type display operating in the normally black mode. This TFT-LCD has a 18.1
inch diagonally measured active display area with SXGA resolution(1024 vertical by 1280 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 16,777,216 colors.
The LM181E1-J3MN has been designed to apply the interface method that enables low power, high
speed low EMI. FPD Link must be used as a LVDS(Low Voltage Differential Signaling) chip.
The LM181E1-J3MN 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 LM181E1-J3MN characteristics provide an excellent flat panel display for office
automation products such as monitors.
