Abstract:
Each pixel of a display device includes: an organic light emitting diode between a first and a second power supply; a first transistor to transmit a drive current based on data signals; a second transistor to couple a gate electrode of the first transistor to the data line in response to a scan signal; 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 data line and a first electrode of the second capacitor, the third transistor including a gate electrode coupled to a selection signal line; and a fourth transistor between the fourth power supply and the third transistor, the fourth transistor including a gate electrode coupled to the first electrode of the second capacitor.
