Product Specification

1. General Description

The LC420WUN is a Color Active Matrix Liquid Crystal Display with an integral External Electrode Fluorescent
Lamp(EEFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive display type which is operating in the normally black mode. It has a 42.02 inch diagonally
measured active display area with WUXGA resolution (1080 vertica l by 1920 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 1.06Bilion (FRC) colors.
It has been designed to apply the 10-bit 2-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

2. Temperature and relative humidity range are shown in the figure below.

Wet bulb temperature should be Max 39¶C, and no condensation of water.

3. Gravity mura can be guaranteed below 40¶C condition.

4. The maximum operating temperatures is based on the test condition that the surface temperature

of display area is less than or equal to 68¶C with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in final product design to prevent the surface temperature of
display area from being over 68୅. The range of operating temperature may degraded in case of
improper thermal management in final product design.

The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn on.

4. Specified Values are for a single lamp which is aligned horizontally.
The life time is determined as the time which luminance of the lamp is 50% compared to that of initial value

at the typical lamp current (

If not used, these pins are no connection. (Please see the Appendix III-4 for more information.)

6. LVDS pin (pin No. #24,25,40,41) are used for 10Bit(D) of the LCD module.
If used for 8Bit(R), these pins are no connection.

7. Specific pin No. #44 is used for “No signal detection” of system signal interface.
It should be GND for NSB(No Signal Black) during the system interface signal is not.
