LM240WU8
Liquid Crystal Display
Product Specification
1. General description
LM240WU8 is a Color Active Matrix Liquid Crystal Display with an integral 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 24 inch diagonally measured active display area with
WUXGA resolution (1200 vertical by 1920 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 LM240WU8's characteristics provide an excellent flat panel display for office automation products
such as monitors.
