Setting value for your reference: 100 k to 1 M .
In order to select an optimum value for resistor R4, you should
reference the LCD and the drive waveform.
Notes: 1. Because of high input impedance on V

to be driven. The value to be selected for C1 and C2
must be able to stabilize the liquid crystal drive
voltage.
[A setting example]
Turn on the voltage regulator circuit and the voltage
follower circuit to apply voltage to V
Display the LCD heavy load patterns (horizontal
stripe-shaped), then select the C2 value that can
stabilize the liquid crystal drive voltages (V
All C2 capacity values selected, however, must be
the same. Then, turn on every built-in power
supplies and select an appropriate C1 value.
