PURPOSE: A display device and a driving method thereof are provided to maintain the uniform luminance of an organic light-emitting device by compensating a data voltage. CONSTITUTION: A display device comprises a plurality of display pixels, a plurality of data lines, and a plurality of sense lines. A plurality of display pixels display an image. A plurality of data lines are connected to the display pixel. A plurality of sense lines are connected to the display pixel. The display pixel comprises a driving transistor(Qd), a capacitor(Cst), a first switching transistor(Qs1), an emitting device, a second switching transistor(Qs2), and a third switching transistor(Qs3). The driving transistor comprises a control terminal, an input terminal, and an output terminal. The capacitor is connected to the control terminal of the driving transistor. The first switching transistor is connected to the control terminal of the driving transistor and data line. The emitting device receives the driving current from the driving transistor. The second switching transistor is connected between the sense line and the emitting device. The third switching transistor is connected between the output terminal and the emitting device of the driving transistor. |
