Liquid Crystal Display
Product Specification
1. General Description
LM270WF5-SLC1 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (White 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 27 inch diagonally measured active display area with Full
HD resolution (1080 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. It is intended to support displays where high brightness, super wide viewing angle,
high color saturation, and high color are important.
