Abstract:
1. A method for driving a display apparatus comprising a display area formed by disposing pixel circuits in a matrix, a signal line drive circuit for processing image data to generate drive signals respectively output to signal lines of the display area, and a scanning line drive circuit for respectively outputting write signals to scanning lines of said display area, wherein each of said pixel circuits includes a light emitting element, a drive transistor for driving said light emitting element by using a drive current, a hold capacitor, and a sampling transistor for setting a voltage at one terminal of said hold capacitor at a voltage of a corresponding one of the drive signals for the signal lines, the method comprising: allowing the light emitting element to emit a light for a light emission time period for which said light emitting element is allowed to emit a light, and stopping the light emitting element from emitting light for a non-light emission time period, wherein the light emission time period and the non-light emission time period are alternately repeated; and setting a voltage developed across terminals of the hold capacitor at a voltage corresponding to one of the drive signals for the signal lines, said setting occurring for the non-light emission time period, in accordance with control for said sampling transistor made in accordance with a corresponding one of the write signals, wherein when there is no change in image data, said scanning line drive circuit stops the control for said sampling transistor made in accordance with a corresponding one of the write signals, and holds said sampling transistor in an OFF state.
