Abstract
The present invention provides a display device and a method of driving the same. The display device includes a plurality of display pixels to display an image, a plurality of data lines connected to the display pixel, and a plurality of sensing lines connected to the display pixel. Each display pixel includes: a driving transistor including 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, the light-emitting element to emit light; a second switching transistor connected between the sensing line and the output terminal of the driving transistor; and a third switching transistor connected between the output terminal of the driving transistor and the light-emitting element, wherein the driving transistor is a p-channel electric field effect transistor.
