DD
Adjustable Sink-Current Output. OUT connects to the resistive voltage-divider between AVDD and GND that sets
the VCOM voltage. I
High-Voltage Analog Supply. Bypass to GND with a 0.1µF capacitor.
3.6V Regulator Output. V
GND with a 0.1µF capacitor.
Ground. Connect to system ground.
EEPROM High-Voltage Programming Supply. Bypass to GND with a 0.1µF capacitor. Connect this pin to the TFT
LCD VGON supply. VGON should be between 16.1V and 28V. The HV pin supplies the power for the internal
EEPROM writing cycle. The internal writing circuits are disabled when HV is less than 15.6V (typ).
