Product Specification
1. General Description
The LM157E2-A2 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 white mode. This TFT-LCD has a 15.7
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 LM157E2-A2 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 LM157E2-A2 is intended to support applications where thin thickness and low power consumption
are critical factors and graphic displays are important. In combination with the vertical arrangement of the
sub-pixels, the LM157E2-A2 characteristics provide an excellent flat panel display for office automation
products such as monitors.
