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.

(frame frequency) = 60Hz condition, whereas full black pattern is displayed.
2. The variance of the voltage is
±
10%.
3. The typical operating current is for the typical surface luminance (L
) in optical characteristics.
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.
