Abstract

A method of driving a pixel element an active matrix display. The method inducing a change of the bias voltage of the first transistor towards its threshold voltage with an essentially constant current provided from the semiconductor channel of a field effect transistor to cause the bias voltage of the first transistor linearly depend upon the time lapse since the light-emitting element starts to emit light. The method also includes terminating light emitted from the light-emitting element after the bias voltage of the first transistor becomes substantially close to the threshold voltage of the first transistor.
