Patent ID: 8289247

Claim:
A display device, comprising: a plurality of display pixels; a plurality of data lines that are connected to the display pixels; and a plurality of sensing lines that are connected to the display pixels, wherein each display pixel comprises: a driving transistor comprising a control terminal, an input terminal, and an output terminal, a capacitor connected to the control terminal of the driving transistor, a first switching transistor connected to the data line and the control terminal of the driving transistor, a light-emitting element to receive a driving current from the driving transistor to emit light, a second switching transistor connected between the sensing line and the light-emitting element, and a third switching transistor connected between the output terminal of the driving transistor and the light-emitting element, wherein the second switching transistor and the third switching transistor are in a turn off state when the first switching transistor is in a turn on state, and wherein the second switching transistor and the third switching transistor are changed from the turn off state to the turn on state when the first switching transistor is changed from the turn on state to the turn off state.
