3.Electrical Specification
The T296XW01 requires two power inputs. One is employed to power the LCD electronics and to drive the
TFT array and liquid crystal. The second input power for the BLU, is to power inverter..

3.
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.
4.
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.
5.
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 will drop and the life time of CCFL will be reduced.

All GND (ground) pins should be connected together and should also be connected to the LCD’s metal
frame. All Vcc (power input) pins should be connected together.
