*1:

VDD–VLC3

*2:

The following relationship must be kept:

VDD>VLC1>VLC2≥VSS

VLC1=VDD –(VDD – VLC3)

VLC2=VDD –(VDD – VLC3)

VLC3=VDD –(VDD – VLC3)

*3:

VDD is the reference potential for the LCD driving voltage. To decide the LCD driving

voltage, change the voltage between VLC3 and VSS (VLC3 > 0).
