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 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-pixe l color is determined with a 8-bit gray scale signal fo r each dot,
thus, presenting a palette of more than 16,7M(True) colors.
It has been designed to apply the 8Bit 1 port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide view ing angle, high color gamut,
high color depth,and fast response time are important.

Notes :

1. The specified current and power consumption are under the typical supply Input voltage, 24.0V.
The ripple voltage of the power supply input voltage is under 0.5 Vp-p.
Inrush current of the power supply input current is under +10% of the typical current.

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.
