The voltage determined in the liquid crystal cell is resistance-
divided or impedance-converted by operational amplifier, and the
resultant voltage is applied.
The potential is determined on the basis of V
equation must be respected.
When the built-in power supply is ON, the following voltages are
given to pins V
Power supply voltage output pin for oscillating circuit.
