Claim Text:
1. A pixel circuit comprising: an organic light emitting diode; a threshold circuit which generates an output signal based on an input signal, wherein the threshold circuit has a hysteresis characteristic with respect to the input signal; a first transistor comprising a first electrode connected to a data line, a second electrode connected to an input terminal of the threshold circuit, and a gate electrode connected to a scan line; a second transistor comprising a first electrode connected to a driving voltage, a second electrode connected to an anode of the organic light emitting diode, and a gate electrode connected to an output terminal of the threshold circuit, wherein the second transistor controls a current amount which flows to the organic light emitting diode from the driving voltage based on the output signal of the threshold circuit; and a storage capacitor comprising a first end electrically and directly connected to the input terminal of the threshold circuit, and a second end connected to the first electrode of the second transistor.
