Table 6-1: Power Supply Pins
System ground pin of the IC.
Grounding for gamma circuit
Grounding for analog circuit.
Grounding for booster circuit.
Booster input voltage pin.
- Connect to voltage source between 2.5V to 3.6V
Voltage supply pin for analog circuit. This pin requires a
noise free path for providing accurate LCD driving
voltages.
- Connect to same source of VCI
Negative voltage of VCI.
Equals to 2x VCI
This pin provides voltage reference for internal voltage
regulator when register VDV[4:0] of Power Control 4
set to “01111”.
- Connect to an external voltage source for reference
This pin indicates a HIGH level of VCOM generated in
driving the VCOM alternation.
This pin indicates a LOW level of VCOM generated in
driving the VCOM alternation.
This pin is the maximum source driver voltage.
A positive power output pin for gate driver and for OTP
programming
A negative power output pin for gate driver.
