Abstract:
1. A manufacturing method of organic flat emitting devices, wherein the organic flat emitting devices comprise a transparent electrode plate, an organic electroluminescent layer, and a metallic cathode, the method comprising the steps of: forming a plurality of separate transparent anodes on a transparent substrate; forming an insulation layer around the transparent anodes by ink-jet printing, the ink-jet printing being accomplished by using at least one ink-jet head to jet insulation material after aligning with an area around the transparent anodes so as to form the insulation layer around the transparent anodes, the aligning being accomplished by mechanical aligning having an aligning precision of no less than about 50 micrometer or the aligning being accomplished by optical aligning having an aligning precision of no less than about 1 micrometer; curing the insulation layer to form the transparent electrode plate; forming the organic electroluminescent layer on the transparent electrode plate having the transparent anodes and the insulation layer; and coating the metallic cathode on he organic electroluminescent layer.
