ACTIVE MATRIX TYPE ORGANIC EL DISPLAY DEVICE AND ITS DRIVING METHOD

摘要

To control a chronological luminance decrease of an organic EL element in an active matrix drive type organic EL display and to provide a reliable organic EL display. An organic EL display comprising a luminance decrease detector to detect a luminance decrease of an organic EL element; a reverse bias voltage generator to generate a reverse bias voltage pulse according to an amount of the luminance decrease; and a controller to control applying the above reverse bias voltage pulse to a driving transistor in a time period in which the organic EL element emits no light.
