摘要
A thin film organic light emitting diode with edge emitter waveguide comprises, in sequence, a substrate, a waveguide, an anode, a hole transport layer, an electroluminescent layer, an electron injection layer and a cathode. Voltage applied between the anode and cathode causes the electroluminescent layer to emit light through the hole transport layer and the anode into the waveguide where the light is internally reflected within the waveguide and propagates through the length of the waveguide to be emitted through the edge of the waveguide. The electron injection layer also functions as a cladding layer to increase the efficiency of the waveguide. The non-emission edge of the waveguide may be sloped with a conductor layer to the anode and a conductor layer to the cathode forming a reflective surface to the non- emission edge.
