Abstract
A pixel compensating circuit includes a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a driving transistor, a first capacitor, and an organic light emitting diode element. The first transistor controls transmission of a data signal to a first electrode plate of the first capacitor. The second transistor controls transmission of a reference voltage signal to the first electrode plate of the first capacitor. The driving transistor determines an amount of a driving current. The third transistor controls connection and disconnection between the gate electrode and a drain electrode of the driving transistor. The fourth transistor transmits the driving current from the driving transistor to the organic light emitting diode element. The fifth transistor controls transmission of a supply voltage to the source electrode of the driving transistor; and the organic light emitting diode element emits light in response to the driving current.
