Abstract:
A power circuit section generates a first logic power supply voltage and an analog power supply voltage to supply to a first power supply line and a second power supply line, respectively. A regulator steps the first logic power supply voltage down to generate a second logic power supply voltage and supplies the second logic power supply voltage to a third power supply line. A logic circuit controls A source line driving section and A gate line driving section in response to a decrease of a voltage of the first power supply line so that the charge stored in the display panel is discharged. A charge transporting path is configured to transport the charge from the second power supply line to a third power supply line in response to the decrease of the voltage of the first power supply line.
