Patent ID: 8154483

Claim:
An image display apparatus comprising: a plurality of pixels circuits, each pixel circuit including a light emitting element operable to emit light while current passes there through; a driver configured to control light emission of the light emitting element, the driver being electrically connected to the light emitting element; a control circuit electrically connected to the light emitting element and driver; and a first capacitor electrically connected to the driver for storing a data voltage; wherein the control circuit detects a voltage applied to the light emitting element and the detected voltage is fed back to the driver at least while the light emitting element is emitting light in a frame, wherein the control circuit includes a second capacitor for storing the detected voltage applied to the light emitting element, the second capacitor having a smaller capacitance than the first capacitor, and wherein an electrical charge in the second capacitor is discharged to be supplied to the first capacitor while the light emitting element is emitting light in the frame.
