Abstract: A circuit for providing a current to an organic light emitting diode comprising: (a) an amorphous silicon field effect transistor having a gate electrode and a drain electrode through which the current is provided to the organic light emitting diode; and (b) a controller for controlling a bias between the gate electrode and the drain electrode to maintain a threshold voltage shift of less than about 1V. The organic light emitting diode is preferably a component in an active matrix.
