Abstract:
1. An OLED device, comprising: an anode, a hole transport layer, a luminance layer, an electron transport layer and a cathode, wherein the hole transport layer, the luminance layer, the electron transport layer and the cathode are orderly formed on the anode by a vacuum thermal evaporation and all have a certain thickness; wherein molecules of a film material of forming the hole transport layer all standing upright on the anode, there forming vertical conjugated planes between the molecules of each molecule layer in the hole transport layer, and the conjugated planes being parallel to each other and perpendicular to the anode; and molecules of a film material of forming the electron transport layer all standing upright on the cathode, there forming vertical conjugated planes between the molecules of each molecule layer in the electron transport layer, and these conjugated planes being parallel to each other and perpendicular to the cathode.
