1. General Description
This specification applies to the 42 inch Color TFT-LCD Module T420HW04 V6. This LCD module has
a TFT active matrix type liquid crystal panel 1920x1080 pixels, and diagonal size of 42 inch. This
module supports 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-pi xel color is determined with a 8-bit gray scale signal for each
dot.
The T420HW04 V6 has been designed to apply the 8-bit 2 channel LVDS interface method. It is
intended to support displays where high brightness, EBU Gamut (72% NTSC), wide viewing angle,
and high color depth are very important. The T420HW04 V6 backlight unit is using inverter solution.

3. Electrical Specification
The T420HW04 V6 requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The second input, w hich powers the CCFL, is typically
generated by an integrate power (I/P) system.

The performance of the Lamp in LCD panel, for example life time or brightness, is extremely
influenced by the characteristics of the balance board and I/P board. All the parameters should be
carefully designed as not to produce too much leakage current from high-voltage output. While
design or order balance board, please make sure unwanted lighting caused by the mismatch of
the lamp and balance board (no lighting, flicker, etc) never occurs. After confirmation, the LCD
Panel 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 has a low luminance and the inverter has abnormal action, because
leakage current occurs between lamp wire and conducting tape.
When operate at low temperatures, the brightness of CCFL will drop and the lifetime of CCFL will
be reduced.
Note:
1. V
2. The backlight power consumption shown above is tested by lamp current I
3. The life is determined as the time at which luminance of the lamp is 50% compared to that of
