Liquid Crystal Display LC104S1-A1
3.
Electrical Specifications
3-1. Electrical Characteristics
The LC104S1-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 specification 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
=3.3V, 25
°
C,f
V
=60Hz condition
whereas Mosaic pattern is displayed and f
V
is the frame frequency.
2. This impedance value is needed to proper display and measured from LVDS T
X
to the mating connector.
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.
