Patent ID: 8345032

Claim:
A display apparatus comprising: a pixel matrix section including pixel circuits laid out to form a pixel matrix to serve as pixel circuits each having an electro optical device configured to provide a light emission period and a no-light emission period, a signal writing transistor for writing a video signal, a signal storage capacitor for holding the video signal written by the signal writing transistor, and a device driving transistor for driving the electro optical device in accordance with the video signal held by the signal storage capacitor, the signal storage capacitor having a first terminal connected to a gate terminal of the device driving transistor and a second terminal connected to a first current terminal of the device driving transistor, and a power-supply section configured to change a power-supply electric potential appearing on a power-supply line that is connected to a second current terminal of the device driving transistor, said change of the power-supply electric potential appearing on the power supply line by the power-supply section comprising a first potential being applied to the power-supply line for providing a driving current flowing through the device driving transistor during the light emission period, the power-supply line being floated by disconnecting the power-supply line from the power-supply electric potential within a first portion of the no-light emission period, and a second potential being applied to the power-supply line during a second portion of the no-light emission period that occurs after the first portion, the second potential being set to cause a reverse bias of the electro optical device, wherein the power-supply section is configured to provide the first potential throughout a write period of writing the video signal.
