3. Electrical Specifications
3-1. Electrical Characteristics
The LC151X01 requires two power inputs. One is employed to power the LCD electronics and to drive the T
FT array and liquid crystal. The second input power for the CCFL, is typically generated by an
inverter. The inverter is an external unit to the LCDs.
Table 2. ELECTRICAL CHARACTERISTICS
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 you instrument.
1. The specified current and power consumption are under the V
CC
=5.0V, 25 C,f
V
=60Hz condition
whereas mosaic pattern(8 x 6) is displayed and f
V
is the frame frequency.
2. The duration of rush current is about 2ms and rising time of Power Input is 1ms(min.).
3. The variance of the voltage is
±
10%.
4. The voltage above V
S
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.
