Manufacturing method of organic flat light-emitting devices
A manufacturing method of organic flat light-emitting devices includes the following steps. First, a transparent substrate is provided, which has several microstructures on its first surface and the microstructures have a maximum height of 100 μm from the first surface. Second, a transparent anode is formed on the second surface of the transparent substrate that is opposite to the first surface. Thirdly, at least one organic electro-luminescent layer is formed on the transparent anode. Finally, a metal cathode is formed on the organic electro-luminescent layer. Another manufacturing method of organic flat light-emitting devices includes the steps of: forming a transparent thin film on a first surface of a transparent substrate, the transparent thin film having a plurality of microstructures with a maximum height of 100 μm; forming a transparent anode on a second surface of the transparent substrate opposite to the first surface; forming at least one organic electro-luminescent layer; and forming a metal cathode on the organic electro-luminescent layer.
1. A manufacturing method of organic flat light-emitting devices, comprising the steps of:
providing a transparent substrate, which has a first surface and a second surface, the first surface being formed with a plurality of microstructures and each of the microstructures having a curved surface, wherein the curved surface is a protruding surface having a square border;
forming a transparent anode on the second surface of the transparent substrate;
forming at least one organic electro-luminescent layer; and
forming a metal cathode on the organic electro-luminescent layer.
2. The manufacturing method of claim 1 , wherein the square border has a side length between 10 μm and 50 μm.
