Patent ID: 8179343

Claim:
A display apparatus comprising: a scanning line; a signal line; and a pixel circuit arranged in a site where the scanning line crosses the signal line, which controls a light emitting element and current to be supplied to the light emitting element, wherein the pixel circuit is selected according to a signal applied to the scanning line, and a signal is input to the selected pixel circuit from the signal line, and the pixel circuit includes: a drive transistor connected to a terminal of the light emitting element; a holding capacitor, having a terminal connected to a gate of the drive transistor; a first switch which opens and closes connection between the terminal of the light emitting element and the signal line in accordance with a signal applied to the scanning line; and a second switch which opens and closes connection between the terminal of the holding capacitor and the signal line in accordance with a signal applied to the scanning line, and wherein first and a second voltage supplies are switchably connected to the signal line, and during a period when the pixel circuit is selected, the first voltage supply is connected to the signal line and the first switch is closed so that a voltage of the first voltage supply is applied to the terminal of the light emitting element, and the second voltage supply is connected to the signal line and the second switch is closed and the first switch is opened, so that a voltage of the second voltage supply is applied to the terminal of the holding capacitor, wherein the voltage of the second voltage supply is a signal voltage for determining the current to be supplied to the light emitting element, the voltage of the first voltage supply is determined based on a terminal-to-terminal voltage of the light emitting element when the voltage of the second voltage supply is applied to the holding capacitor and current flows in the light emitting element, and supply of the voltage of the second voltage supply is performed after supply of the voltage of the first voltage supply.
