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
active display area with WXGA resolution (768 vertical by 1366 horizontal pixel ar

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.

Note: 1. If Pin9 is Ground, interface format is “LG”, and if Pin9 is Vcc(3.3V), interface format is “DISM”

See page 9 and 10.

2. Pin30 is necessary for LCD test.
When LVDS signals are abnormal operation more than 3-Vsync times and power 12V is supplied,

‘Open’ or ‘Vcc’ : LCD operate itself some test patterns.(AGP – Auto Generation Pattern)
‘Ground’ : LCD operate itself a black pattern. (NSB – No Signal Black)

LPL recommends ‘Ground’ for NSB.

3. All GND(ground) pins should be connected together, which should be also connected to the LCD
module metal frame.

4. All V

LCD (power input) pins should be connected together.

5. Input Levels of LVDS signals are based on the IEA 664 Standard.
