1. A pixel comprising:

  • an organic light emitting diode; and

    a pixel circuit electrically connected to at least one scan line and at least one data line, the pixel circuit including a capacitor, wherein the scan line and the data line are configured to charge the capacitor in response to the first data signal with a voltage corresponding to a difference between a first power supply and a first data signal and to charge the capacitor with a voltage corresponding to a current signal when the current signal is being sunk, wherein the pixel circuit is configured to control the amount of current supplied to a second power supply from the first power supply through the organic light emitting diode according to the voltage stored in the capacitor.
