3. Electrical Specification
The design of the inverter must have specifications for the lamp in LCD Assembly.
The performance of the Lamp in LCM, for example lifetime 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.
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℃ or 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 lifetime of CCFL will be reduced.
3-1 Electrical Characteristics
The T140VN01 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.
