Abstract:
A display device includes: a pixel circuit including a switching transistor connected to a data line, a storage capacitor connected to the switching transistor, a driving transistor connected to the storage capacitor, an organic light-emitting diode connected to the driving transistor and a sensing transistor connected between a sensing line and the driving transistor; and a data-sensing circuit including a first selector connected to the data line and the sensing line, a second selector connected to an output terminal of an amplifier, he first selector and a feedback capacitor, where the second selector selectively connects the output terminal of the amplifier to the first selector and the feedback capacitor, a third selector connected to the sensing line, and a fourth selector connected to the output terminal of the amplifier and the third selector.
