Abstract

See full text

An electroluminescent device described herein, in one aspect, comprises a first electrode and second electrode and a light emitting layer positioned between the first and second electrodes. A current injection gate is positioned between the first electrode and the light emitting layer or the second electrode and the light emitting layer. In some embodiments, the current injection gate comprises a semiconductor layer of electronic structure restricting injected current flow from the first or second electrode through the semiconductor layer as a function of alternating current voltage frequency applied to the first and second electrodes.
