3. Electrical Specifications

3-1. Electrical Characteristics

The LB104V03-A1 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 inverter is an external unit to the LCD.

Note)

The design of the inverter must have specifications for the lamp in LCD Assembly. 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. The voltage above VS should be applied to the lamps for more than 1 second for start-up. Otherwise, the

lamps may not be turned on. The used lamp current is the lamp typical current.
