3-1. Electrical Characteristics
Note :
1. Permissive power ripple should be measured under VCC=12.0V, 25°C, fV(frame frequency)=MAX
2. The specified current and power consumption are under the V
3. The current is specified at the maximum current pattern.
4. Maximum Condition of Inrush current :
MODULE :
It requires two power inputs. One is employed to power the LCD electronics and to drive the TFT 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.

Rush current
The duration of rush current is about 2ms and rising time of Input Voltage is 1ms(min.).
At any rising time of Input voltage, Keep the I2T Value by below Condition
Ver 0.0
condition and At that time, we recommend the bandwidth configuration of oscilloscope is to be under
20Mhz. See the next page.
whereas Mosaic and max power pattern shown in the [ Figure 3 ] is displayed.
Condition : I2T < 32*2ms
