Thermal transfer element and process for forming organic electroluminescent devices
First Claim
1. A method for making an organic electroluminescent device comprising the steps of:
- providing a receptor substrate that includes an electrode and a pattern of spaced insulators on the electrode that leaves at least a portion of the electrode exposed; and
selectively thermally transferring an organic light emitting material from a thermal transfer donor element to the receptor to cover at least a portion of the exposed electrode.

Abstract
Disclosed are thermal transfer elements and processes for patterning organic materials for electronic devices onto patterned substrates. These donor elements and methods are particularly suited for making organic electroluminescent devices and displays. The donor elements can include a substrate, and optional light-to-heat conversion layer, and a single or multicomponent transfer layer that can be imagewise transferred to a receptor to form an organic electroluminescent device, portions thereof, or components therefor, The methods offer advantages over conventional patterning techniques such as photolithography, and make it possible to fabricate new organic electroluminescent device constructions.
