1. General Description
This specification applies to the 42 inch Color TFT-LCD Module T420HW02 V0. 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 for each
dot.
The T420HW02 V0 has been designed to apply the 8-bit 2 channel LVDS interface method. It is
intended to support displays where high brightness, wide viewing angle, high color saturation, and

3. Electrical Specification
The T420HW02 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 inverter.

The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced
by the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be
carefully designed so as not to produce too much leakage current from high-voltage output of the
inverter. When you design or order the inverter, please make sure unwanted lighting caused by
the mismatch of the lamp and the inverter (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.

μ
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
leakage current occurs between lamp wire and conducting tape.

The relative humidity must not exceed 80% non-condensing at temperatures of 40
temperatures greater than 40
at low temperatures, the brightness of CCFL will drop and the lifetime of CCFL will be reduced.

2. The Backlight power consumption shown above does include loss of external inverter at 25
The used lamp current is the lamp typical current
3. The life is determined as the time at which luminance of the lamp is 50% compared to that of
