Abstract
A pixel circuit includes a first transistor transmitting a reference signal or a data signal in response to a selection signal applied through a scan line, second and third transistors inputting a reference current in response to a control signal applied through a control line, a first capacitor storing a voltage compensated by the input reference current to compensate for the data signal received from the first transistor, a second capacitor storing the compensated data signal by the first capacitor, a fourth transistor receiving the compensated data signal to generate a driving current, a fifth transistor transmitting the driving current in response to the control signal applied through the control line, and an organic light emitting diode receiving the driving current from the fifth transistor to emit light.
