Abstract
A pixel circuit includes: an organic light emitting diode ('OLED'); a threshold circuit which generates an output signal based on an input signal, where the threshold circuit has a hysteresis characteristic with respect to the input signal; a first transistor including 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; and a second transistor including a first electrode connected to a first power, 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, where the second transistor controls a current amount that flows to the organic light emitting diode from the first power based on the output signal of the threshold circuit.
