Product Specification
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.

Note :
1. The specified characteristics perform under the VLCD=5.0V, 25 2°C, fV=60Hz condition.
fV is the frame frequency.
2. Permissive Power Ripple should be measured under VLCD=5.0V, 25 2°C,
fV =75Hz condition and At that time,
we recommend the bandwidth configuration of oscilloscope is to be under 20MHz. (See FIG.3)
3. Mosaic pattern(8 x 6) is displayed.
4. Input current is specified at the maximum current pattern.
5. The duration of Inrush current is about 5ms and rising time of power Input is 500us 20%.
