1. General Description

LD420WUN is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode 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 Public Display where high brightness, super wide viewing angle, high color gamut, high color depth and fast moving picture response time are important.

Notes :

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.

Notes :

1. The pin no 44 is LCD Test option. “AGP” (Auto Generation LCM operates Pattern) or “NSB” (No Signal Black) is case that LVDS signals are out of frequency or abnormal condition in spite of 12 volt power supply. LPL recommends “NSB”. ( AGP : “VCC” or “OPEN” / NSB : “GND” )

2. All GND(ground) pins should be connected together to the LCD module’s metal frame.

3. All VLCD (power input) pins should be connected together.

4. All Input levels of LVDS signals are based on the IEA 664 Standard.

5. Specific pins(pin No. #1~#10) are used for internal data process of the LCD module.

If not used, these pins are no connection.

6. If DCR function should be enable(‘H’), 10th pin must be connected to serial resistor which value is under 1k ohm.
