Abstract
Official abstract text for this publication.
Techniques for fabricating organic light emitting devices, and devices fabricating using the disclosed techniques, are provided. In the disclosed techniques, a layer including an emissive material and a buffer material may be deposited in a single laser transfer process, such as a laser-induced thermal imaging process. The emissive and buffer materials may be deposited in discrete layers during the transfer process. Examples of buffer materials as disclosed include blocking materials, transfer materials, and the like. Additional layers may be deposited using conventional techniques or additional laser transfer processes.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: depositing a first layer over a substrate; depositing a second layer over the first layer via a laser transfer process, the second layer comprising a first emissive material and a first buffer material, the first emissive material forming a layer having a first side and a second side that is opposite to the first side, wherein the first buffer material is disposed on the first side of the first emissive material for application t…
