Liquid Crystal Display
Product Specification
1. General description
LM220WE1-TLM1 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) 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 22 inch diagonally measured active
display area with WSXGA+ resolution (1050 vertical by 1680 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 LM220WE1-TLM1 characteristics provide an excellent flat panel display for
office automation products such as monitors.
