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.
