Organic light-emitting diode for N-type doping membrane

The invention discloses an organic light-emitting diode for an N-type doping membrane, and relates to an organic light-emitting diode, in particular to an organic light-emitting diode which has a dual-layer N-type doping membrane structure and is formed by an N-type doped organic transmission material and an N-type doped organic electron acceptor material. The organic light-emitting diode consists of a layer of transparent anode, an organic hole injection layer deposited on the anode, an organic hole transport layer deposited on the organic hole injection layer, an organic light-emitting layer deposited on the organic hole transport layer, an N-type doped organic electron injection layer deposited on the organic light-emitting layer, an N-type doped organic electron transmission layer deposited on the N-type doped organic electron injection layer and a layer of cathode deposited on the organic electron transmission layer. In the invention, the dual-layer N-type doping membrane structure which has low cost and is easy to process is provided, and the electron current and heat stability of the organic light-emitting diode are improved, so the organic light-emitting diode can be applied to organic panel display, solid illumination, organic solar batteries and organic field effect transistors.
