LM201WE2
Liquid Crystal Display
Product Specification
1. General Description
LM201WE2 is a Color Active Matrix Liquid Crystal Display with anintegral Cold Cathode Fluorescent
Lamp(CCFL) backlight system. The matrix employs a-SiThin Film Transistor as the active element.
It is a transmissivetype display operating in the normally black mode. It has a 20.1 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(True) colors.
Ithas 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.

3. Electrical Specifications
3-1. Electrical Characteristics
It requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and
liquid crystal. The second input power for the CCFL, is typically generated by an inverter. The inverter is an
external unit to the LCDs.

2. The current is specified at the maximum current pattern.
3. The duration of rush current is about 2ms and rising time ofpower Input is 1ms(min.).

1. The input voltage ripple is limited below 400mVp-p.
2.The specified current and power consumption are under the typical supply Input voltage, 24V.
3.The life is determined as the time at which luminance of the lamp is 50% compared to that of initial
value at the typical lamp current on condition of continuousoperating at 25 ± 2°C.
4. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately
30min in a dark environment at 25 °C± 2°C.
