Abstract:
A method for fabricating an organic light emitting diode, comprising:providing a substrate; providing a fixture that is fixed on the substrate and moves forward in a horizontal direction over a plurality of depositional sources, including an anode depositional source, an organic emitting layer depositional source and a cathode depositional source, wherein all the depositional sources are fixed in a position along a moving route; moving the substrate fixed on the fixture over the anode depositional source to form an anode; moving the substrate over the organic emitting layer depositional source before the anode depositional source completes the anode to form an organic emitting layer; moving the substrate over the cathode depositional source before the organic emitting layer depositional source completes the organic emitting layer to form a cathode, wherein a heterojunction between the anode and the organic emitting layer, and a heterojunction between the organic emitting layer and the cathode are blurred.
