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.
