adjusting circuit
specified according to liquid crystal cells is impedance-converted
Commonly used with the MPU power supply pin V
0 V pin connected to the system ground (GND)
Boosting circuit reference power supply for liquid crystal drive
External input pin for liquid crystal power supply voltage
They are set to OPEN
Multi-level power supply for liquid crystal drive. The voltage
by a split resistor or operation amplifier (OP amp) and applied.
The potential needs to be specified based on V
relationship of dimensions shown below:
Master operation When the power supply is ON, the following
voltages are applied to V
circuit. The selection of the voltages is determined using the LCD
bias set command.
Boosting capacitor positive side connecting pin. Connects
a capacitor between the pin and CAP1– pin.
Boosting capacitor negative side connecting pin. Connects
a capacitor between the pin and CAP1+ pin.
Boosting capacitor positive side connecting pin. Connects
a capacitor between the pin and CAP2– pin.
Boosting capacitor negative side connecting pin. Connects
a capacitor between the pin and CAP2+ pin.
Boosting capacitor negative side connecting pin. Connects
a capacitor between the pin and CAP1+ pin.
Boosting output pin. Connects a capacitor between the pin and V
Voltage adjusting pin. Applies voltage between V
a split resistor.
