Patent ID: 6855636

Claim:
A process for forming organic electroluminescent devices comprising the steps of: providing a display substrate having one or more addressable first electrode layers thereon; forming one or more organic electroluminescent layers over at least a portion of the one or more first electrodes on the substrate, thereby defining one or more organic electroluminescent stacks, each stack comprising a portion of one of the one or more organic electroluminescent layers on a portion of one of the one or more first electrode layers; selectively thermally transferring a plurality of insulators from a thermal transfer donor sheet onto the one or more organic electroluminescent layers, leaving exposed at least two portions of the one or more organic electroluminescent stacks; and depositing a second electrode after the step of transferring the plurality of insulators, thereby forming at least two organic electroluminescent devices separated by one or more of the insulators.
