Power supply pin for logic circuit
Power supply pin for booster
Ground pin for logic and driver circuits
Power supply pin for driver. Output pin for on-chip booster.
Connect a 1 µ F boost capacitor between this pin and the GND
pin.
If not using the on-chip booster, a direct driver power supply can
be input.
These are reference power supply pins for the LCD driver.
Connect a capacitor between these pins and the GND pin if an
internal bias has been selected.
These are capacitor connection pins for the booster. When
using the on-chip booster, connect a 1 µ F capacitor between
positive (+) and negative (-) pins.
This is a capacitor connection pin for boost adjustment. When
using the on-chip booster, connect a 1 µ F capacitor between
this pin and the GND pin.
