PATTERNING OF THIN FILMS FOR THE FABRICATION OF ORGANIC MULTI-COLOR DISPLAYS |
摘要 |
Organic light emitting devices and methods of making them are described. The devices contain a substrate, a first electrical contact layer, a patterned organic layer, and a second electrical contact layer. A covering portion covers the sides of the organic layer, protecting the same. In the methods, a first organic layer is provided over a first electrical contact layer, followed by a patterned second electrical contact layer. The organic layer is etched using the patterned electrical contact layer as a mask. In one embodiment, the etching step exposes an area over the first electrical contact layer, and a second organic layer is provided over the exposed area. |
