Abstract
An organic light emitting diode with dielectric barriers (120, 106) at both the anode-organic and the cathode-organic interfaces.
Claims7
A light emitting diode, comprising:
- (a) an anode;
- (b) a hole transport layer on said anode, said hole transport layer including a first organic semiconductor material;
- (c) an electron transport layer on said hole transport layer, said hole transport layer including a second organic semiconductor material;
- (d) a cathode on said electron transport layer;
- (e) wherein said anode includes a tunneling barrier at an interface with said hole transport layer.
2 more elements
A light emitting diode, comprising:
- (a) an anode;
- (b) a cathode spaced from said anode;
- and
- (c) a layer of organic material between said anode and said cathode, said layer providing hole transport from said anode, electron transport from said cathode, and light emission;
- (d) wherein said anode includes a tunneling barrier at an interface with said layer.
