Patent abstract

A light-emitting diode apparatus and a control method of the light-emitting diode apparatus are provided. The control method includes: applying a pre-reset voltage to a control terminal of a driving transistor of the light-emitting diode apparatus in a pre-resetting stage to pre-reset the control terminal of the driving transistor; resetting the control terminal of the driving transistor of the light-emitting diode apparatus by using a reset voltage source in a first resetting stage; compensating the control terminal of the driving transistor to a compensation voltage in a compensation stage; and providing, by the driving transistor, a driving current in a light emission stage to drive a light-emitting diode of the light-emitting diode apparatus to emit light.
