Abstract
The present invention provides a method for pattering oriented materials to make organic electronic displays or devices. The method includes selective thermal transfer of an oriented electronically active or emissive material from a thermal transfer donor sheet to a receptor. The method can be used to make organic electroluminescent devices and displays that emit polarized light. The method can also be used to make organic electronic devices with enhanced charge mobility properties. The present invention also provides donor sheets for use with the method, and methods for making donor sheets that include transfer layers having oriented electronically active organic materials.
