Power supply Ground Voltage converter input/output pin. Capacitor 1 negative connection pin for voltage converter. Capacitor 1 positive connection pin for voltage converter. Capacitor 2 positive connection pin for voltage converter. Capacitor 2 negative connection pin for voltage converter. LCD driver supply voltages. The voltage determined by LCD pixel is impedance-converted by an operational amplifier for application.
