1. General Description
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 type display operating in the normally black mode. It has a 42 inch diagonally measured
active display area with WUXGA 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 luminance of the sub-pixel color is determined with a 8bit or 10-bit gray scale signal for
each dot, thus presenting a palette of more than 1.06Billion of 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 moving picture response time are important.

1. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 120
minutes at 25·2¶C. The specified current and power consumption are under the typical supply Input voltage
24Vand V
BR (VBR-A : 1.65V & VBR-B :3.3V), it is total power consumption.
The ripple voltage of the power supply input voltage is under 0.5 Vp-p. LPL recommend Input Voltage is
24.0V · 5%.
2. Electrical characteristics are determined within 30 minutes at 25·2¶C.
The specified currents are under the typical supply Input voltage 24V.
3. The brightness of the lamp after lighted for 5minutes is defined as 100%.
TS is the time required for the brightness of the center of the lamp to be not less than 95% at typical current.
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 (V
BR-A : 1.65V & VBR-B :3.3V), on condition of continuous operating at 25· 2¶C
5. The duration of rush current is about 10 ms.

4. Specific pins(pin No. #2~#6) are used for internal data process of the LCD module.
If not used, these pins are no connection.
5. Specific pins(pin No. #8~#9) are used for Inverter test of the LCD module.
If not used, these pins are no connection.
6. Specific pin No. #44 is used for “No signal detection” of system signal interface.

3-5. Color Data Reference
The brightness of each primary color(red,green,blue) is based on the 10bit(D) gray scale data input for the color.
The higher binary input, the brighter the color. Table 8 provides a reference for color versus data input.
