Abstract
An organic electroluminescent device, particularly for use as a display, is disclosed which is driven according to a pulsed mode of operation which allows much higher current densities to be injected into the device. This is achieved by selection of particular pulse durations and duty cycles, and by an improved geometry for the electroluminescent device in which the resistance of anode lines is reduced.
