摘要（英）：

A pixel capable of compensating for the threshold voltage of a driving transistor, the voltage drop of a first power source and degradation of an organic light emitting diode is provided. The pixel includes an organic light emitting diode; a second transistor (e.g., a driving transistor) coupled between the first power source and the organic light emitting diode to control the current supplied tothe organic light emitting diode; a third transistor coupled between a first electrode of the second transistor and the first power source; a first transistor coupled between a gate electrode of the second transistor and a data line; a first capacitor coupled between the gate electrode and the first electrode of the second transistor; a second capacitor coupled between the first electrode of the second transistor and the first power source; and a compensation circuit coupled between the organic light emitting diode and the gate electrode of the second transistor for adjusting a voltage of thegate electrode of the second transistor in accordance with degradation of the organic light emitting diode.
