Product Specification

1. General Description

The LC420WU2 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) 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 W UXGA resolution (1080 vertical 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 8-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 16.7M(true) colors.
It has been designed to apply the 8-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.

Life Time

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 24V and Vbr 1.65V,
it is total power consumption.
The ripple voltage of the power supply input voltage is under 0.4 Vp-p.
LPL recommend Input Voltage is 24.0V ± 5%.

2. 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 continuous operating at 25 ± 2°C.
Specified value is when lamp is aligned horizontally.

3. The lamp life time for LCM is guaranteed minimum 50,000 hours when Vbr(Analog) and Vbr-B(Burst)
are maximum values.

Note :

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.
