Claim Text:
1. A display device comprising: a scan driver configured to transmit a plurality of scan signals to a plurality of scan lines; a data driver configured to transmit a plurality of data signals to a plurality of data lines; a selector driver configured to transmit a plurality of selection signals to a plurality of selection signal lines; a sensor driver configured to receive a plurality of output signals through the plurality of data lines; and a plurality of pixels coupled to the scan lines, the data lines, and the selection signal lines, wherein each of the plurality of pixels comprises: an organic light emitting diode between a first power supply and a second power supply; a first transistor configured to transmit a drive current based on the data signals to the organic light emitting diode; a second transistor configured to couple a gate electrode of the first transistor to a corresponding data line of the data lines in response to one of the plurality of scan signals; a first capacitor between the first power supply and the gate electrode of the first transistor; a light receiving element coupled to a third power supply; a second capacitor between the light receiving element and a fourth power supply; a third transistor between the corresponding data line and a second electrode of the second capacitor, the third transistor comprising a gate electrode coupled to one of the plurality of selection signal lines; and a fourth transistor between the fourth power supply and the third transistor, the fourth transistor comprising a gate electrode coupled to a first electrode of the second capacitor.
