Patent ID: 8289313

Claim:
A display device comprising one or more pixels, each pixel being associated with a first signal, a second signal, a third signal, and a fourth signal, each pixel comprising: (a) a light-emitting device; (b) a driving transistor for outputting a current to the light-emitting device, the driving transistor comprising an input terminal, an output terminal, and a control terminal; (c) a data voltage terminal for receiving data voltages; (d) a plurality of switching transistors comprising: (1) a switching transistor controlled by the associated first signal, and connected between the data voltage terminal and the input terminal of the driving transistor; (2) a switching transistor controlled by the associated second signal, and connected between a driving voltage terminal and the input terminal of the driving transistor; (3) a switching transistor controlled by the associated third signal, and connected between an output terminal of the driving transistor and a first terminal of the light-emitting device; (4) a switching transistor controlled by the associated fourth signal, and connected between the output terminal of the driving transistor and the control terminal of the driving transistor; wherein each pixel further comprises a first capacitor connected between the control terminal of the driving transistor and the driving voltage terminal; wherein the display device further comprises a control circuit for generating control signals which include the first, second, third and fourth signals associated with the one or more pixels, the control signals being generated for one or more consecutive first periods of time and acting to reset a voltage at the first terminal of the light-emitting device in each first period of time.
