LM270WF1
Liquid Crystal Display
Product Specification
1. General Description
LM270WF1 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) backlight system without inverter. The matrix employs a-Si Thin Film Transistor as the active
element. It is a transmissive type display operating in the normally black 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.
