3. Electrical specifications
3-1. Electrical characteristics
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 LED Backlight, is typically
generated by an LED Driver. The LED Driver is an external unit to the LCDs.

1. The specified current and power consumption are
under the VLCD=12.0V, 25 2°C,fV=60Hz condition
whereas mosaic pattern(8 x 6) is displayed and fV is the frame frequency.
2. The current is specified at the maximum current pattern.
3. Permissive power ripple should be measured under VCC=12.0V, 25°C, fV (frame frequency)=Max
condition and At that time, we recommend the bandwidth configuration of oscilloscope
is to be under 20MHz.
4. The duration of rush current is about 2ms and rising time of power Input is 500us 20%.
