1. General Description

This specification applies to the 42 inch Color TFT-LCD Module T420HW04 V1. This LCD module has

a TFT active matrix type liquid crystal panel 1920x1080 pixels, and diagonal size of 42 inch. This

module supports 1920x1080 Full-HD mode (Non-interlace).

Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.

Gray scale or the brightness of the sub-pixel color is determined with a 8-bit gray scale signal and

Frame Rate Control (FRC) for each dot.

The T420HW04 V1 has been designed to apply the 10bits 4 channel LVDS interface method. It is

intended to support displays where high brightness, wide viewing angle, high color saturation, and

www.panelook.com

high color depth are very important.

T420HW04 V1 Backlight unit used C-balance board (inverter-less) solution. This backlight unit should

bundle integral TV power system to use.

3. Electrical Specification

The T420HW04 V1 requires two power inputs. One is employed to power the LCD electronics and to

drive the TFT array and liquid crystal. The second input, which powers the CCFL, is typically

generated by an power system.

Life Time - 50000 Hours 2

The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced

by the characteristics of the Integrated Power Board (IPB). All the parameters of an IPB should be

carefully designed so as not to produce too much leakage current from high-voltage output of the

IPB. When you design or order the IPB, please make sure unwanted lighting caused by the

mismatch of the lamp and the IPB (no lighting, flicker, etc) never occurs. When you confirm it, the

LCD Assembly should be operated in the same condition as installed in your instrument.

Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to conducting

tape, TFT-LCD Module have a low luminance and the inverter has abnormal action because

3-5 Color Input Data Reference

The brightness of each primary color (red, green and blue) is based on the 8 bit gray scale data input

for the color; the higher the binary input, the brighter the color. The table below provides a reference for

color versus data input.
