LM190WX1
Liquid Crystal Display
Product Specification
1. General Description
LM190WX1-TLH1 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 19.0 inch diagonally measured active
display area with WXGA+ resolution (900 vertical by 1440 horizontal pixel array) Each pixel is divided into Red,
l
Green and Blue sub-pixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the
tia
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
en
power are critical factors and graphic displays are important. In combination with the vertical arrangement of
the sub-pixels, the LM190WX1-TLH1 characteristics provide an excellent flat panel display for office
automation products such as monitors.
