*14: The logic circuit of this IC’s power supply VDD - VSS controls the driver of the LCD power supply VDD - V
power supply VDD - VSS is cut off when the LCD power supply VDD - V has still any residual voltage, the driver (COM.
SEG) may output any uncontrolled voltage. When turning off the power, observe the following basic procedures:
• After turning off the internal power supply, make sure that the potential V ~ V has become below the threshold
