WHITE ORGANIC LIGHT EMITTING DEVICE

摘要

The present invention provides a white organic light-emitting device having a substrate, an organic light-emitting unit and an efficiency-enhancing layer. The organic light-emitting unit has a first electrode, a second electrode and an organic layer. The first electrode is disposed on the substrate. The second electrode is disposed opposite to the first electrode. The organic layer is disposed between the first electrode and the second electrode. The efficiency-enhancing layer is disposed on a light-emitting surface of the organic light-emitting unit. The efficiency-enhancing layer can effectively adjust the chromaticity coordinates value and improve light efficiency of the white organic light-emitting device so that directly adjusting the internal structure of the organic light-emitting unit can be avoid.

主权项

1. A white organic light-emitting device comprising:
a substrate; an organic light-emitting unit having a first electrode, a second electrode, an organic layer and a light-emitting surface, wherein the first electrode is disposed on the substrate and is an anode, the second electrode is disposed opposite to the first electrode and is a cathode, the organic layer is mounted between the first electrode and the second electrode, and the light-emitting surface is located at the first electrode; and an efficiency-enhancing layer being mounted on the light-emitting surface of the organic light-emitting unit, wherein the efficiency-enhancing layer is disposed between the first electrode and the substrate; and the efficiency-enhancing layer is constructed by orderly laminating a first silicon dioxide layer, a first silicon nitride layer, a second silicon dioxide layer and a second silicon nitride layer on the substrate.
