Abstract
The present invention discloses a pixel compensation circuit and method for an organic light emitting display. The circuit comprises a first transistor, a second transistor, a third transistor, a fourth transistor, a driving transistor, a capacitor, and an organic light emitting element. The first transistor transmits a data signal to a first plate of the capacitor; the second transistor applies a reference voltage to the first plate of the capacitor; the driving transistor determines a magnitude of a driving current; the third transistor establishes a connection between the gate electrode and the drain electrode of the driving transistor; the fourth transistor passes the driving current from the driving transistor to the organic light emitting element; and the organic light emitting element emits light in response to the driving current.
