Product Specification
1. General Description
LM230WF3 is a Color Active Matrix Liquid Crystal Display with a 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 23 inch diagonally measured

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 A-FRC (Advanced Frame Rate Control).
It has been designed to apply the 8Bit 2 port LVDS interface.
It is intended to support displays where high brightness, super wide viewing angle,
high color saturation, and high color are important.
