Product Overview 18.1” SXGA TFT Display-Module
The LG Electronics model LM181E1 LCD is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Tube(CCFT) 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 white 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 16,581,375 colors.
LM181E1 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 LCD is intended to support applications where high brightness, wide viewing angle are critical factors and graphic displays
are important. In combination with the vertical arrangement of the sub-pixels, the LM181E1 characteristics provide an excellent flat panel
display for office automation products such as monitors.
