Inorganic electroluminescent device with controlled hole and electron injection

摘要

An electroluminescent device using an inorganic phosphor configured to produce electroluminescence from the recombination of injected holes and injected electrons is disclosed. A controllable hole injection structure in contact with the inorganic phosphor controls a rate of hole injection into the inorganic phosphor based on a first applied control voltage. A controllable electron injection structure in contact with the inorganic phosphor and separated from the controllable hole injection structure controls a rate of electron injection into the inorganic phosphor based on a second applied control voltage.
