发明名称 Display apparatus and driving method of display apparatus
摘要 A display apparatus includes a scanning line, a signal line, and a pixel circuit. 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. The pixel circuit include a holding capacitor, a first switch which opens and closes connection between one 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 one terminal of the holding capacitor and the signal line in accordance with a signal applied to the scanning line. 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 a 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 one terminal of the holding capacitor. A voltage of the first voltage supply is determined based on a terminal-to-terminal voltage of the light emitting element when a voltage of the second voltage supply is applied to the holding capacitor and current flows in the light emitting element.
