General Description
1.
is specification applies to the 42 inch Color TFT-LCD Module T420XW01 V0. This LCD module has
Th
a TFT active matrix type liquid crystal panel 1366x768 pixels, and diagonal size of 42 inch. This
module supports 1366x768 WXGA 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 T420XW01 V0 has been designed to apply the 8-bit 1 channel LVDS interface method. It is
intended to support displays where high brightness, wide viewing angle, high color saturation, and
high color depth are very important.

e T420XW01 requires two power inputs. One is employed to power the LCD electronics and to drive
Th
the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by
an inverter.

Th
e 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

onfirm 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
leakage current occurs between lamp wire and conducting tape.
The relative humidity must not exceed 80% non-condensing at temperatures of 40or less. At
temperatures greater than 40 , the wet bulb temperature must not exceed 39 . When operate
at low temperatures, the brightness of CCFL wi ll drop and the lifetime of CCFL will be reduced.

2. The lamp power consumption shown above does include loss of external inverter at 25.The
used lamp current is the lamp typical current
