NOTE: VSS0, VSS1 and VSS2 must be shorted to external wire.

LCD driver supply voltages

These voltages are determined by LCD pixel is impedance, and converted by

operational amplifiers for application.

Voltages should have the following relationship;

VOUT ≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ VSS

I/O When the internal power circuit is active, these voltages are generated as following table

according to the state of LCD bias.
