LC420W02
Liquid Crystal Display
Product Specification
1. General Description
LC420W02 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 type display operating in the normally black mode. It has a 42.0 inch diagonally measured
acti ve d ispl a y area wi th WXGA reso lution (768 vertical by 1366 horizontal pixel ar ray)
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 8-bit gray scale signal for each dot,
thus, presenting a palette of more than 16,7M(True) colors.
It has been designed to apply the 8-bit 1 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.

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, it is total power
consumption.
Ripple voltage of the Power Supply Input Voltage is under 0.2 Vp-p.
LPL recommend Input Voltage is 24.0V 5%.
(Philips system should keep the input voltage as 25.5V 2%)
2. Brightness Control
This VBR Voltage control brightness.
VBR Voltage Function
3.3V Maximum Brightness (100%)
0V Minimum Brightness.(15~25%)
3. The Life Time 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.
