Power supply pin for logic and booster circuit.
Ground pin for logic and driver circuit.
Driver power supply pin. Output pin of internal booster circuit.
Please connect with a 1 F booster capacitor to ground.
When not using the internal booster circuit, the driver power
can be turned on directly.
Reference power supply pin for LCD drive.
When the internal bias is selected, be sure to leave it open.
When display contrast is bad, connect a capacitor between
these pins and ground.
When the internal bias is selected, Connecting these pins
outside the IC, the bias level can be changed.
Capacitor connection pins for booster circuit. When using
internal booster circuit, connect a 1 F capacitor between
these pins.
