Abstract
A method for fabricating an organic light emitting diode. The method forms an anode, an organic emitting layer and a cathode sequentially on a substrate. When the interface between the anode and the organic emitting layer is forming, the depositional rate of the anode on the substrate is decreasing and the deposition rate of the organic emitting layer on the substrate is increasing. When the interface between the organic emitting layer and the cathode is forming, the deposition rate of the organic emitting layer on the substrate is decreasing, and the deposition rate of the cathode on the substrate is increasing. This method can form a hazy heterojunction between the anode, the organic emitting layer and the cathode, thus forming an organic light emitting diode with a hazy heterojunction.
