Abstract: A light-emitting diode device control method includes using a reset voltage source to reset a control terminal of a driving-transistor of the light-emitting diode device; compensating the control terminal of the driving-transistor to a compensation voltage level; resetting a first terminal of the driving transistor to a target voltage level so as to increase a voltage difference between the first terminal and a second terminal of the driving transistor; and the driving transistor providing a driving current for driving a light-emitting diode of the light-emitting diode device to emit light.

Abstract: The present disclosure relates to a pixel circuit including a light emitting element, a driving circuit, a first data storage circuit and a second data storage circuit. The driving circuit is electrically coupled to the light emitting element. The first data storage circuit is electrically coupled to the driving circuit, and is configured to transmit a first data signal to the driving circuit during a first frame period, so that the driving circuit drives the light emitting element according to the first data signal. The second data storage circuit is electrically coupled to the driving circuit, and is configured to receive a second data signal during the first frame period.
