Product Specification
1. General Description
LM270WQHD is a Color Active Matrix Liquid Crystal Display with Light Emitting Diode ( White LED) backlight
system without LED driver. 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 27inch diagonally measured
a cti ve di spla y a re a w ith Q H D re sol utio n ( 2 5 6 0 ve r tica l b y 1 4 4 0 hori zo n ta l pixe l a r ra y)
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 10-bit gray scale signal for each dot,
thus, presenting a palette of more than 1.07B colors with FRC (Frame Rate Control).
It has been designed to apply the 10-bit 4Lane Display port interface.
It is intended to support displays where high brightness, super wide viewing angle,
high color saturation, and high color are important.
