Patent ID: 8344360

Claim:
A device comprising: a substrate having a cell region defined on a main surface of the substrate, the cell region comprising at least one active component formed thereon, wherein the active component in the cell region comprises one or more OLED cells, and each OLED cell comprises an organic functional layer and a conductive layer, wherein the organic functional layer is configured to emit visible radiation by recombination of charge carriers; a sealing dam on the substrate surrounding the cell region, wherein the sealing dam includes a photosensitive or photopatternable material; a cap supported by the sealing dam wherein the conductive layer is located between the cap and the organic functional layer and wherein a cavity is located between the one or more OLED cells and the cap; spacer particles distributed in the cell region, the spacer particles configured and at least partially arranged in the cavity so that the cap does not contact the one or more OLED cells in the cell region and wherein the spacer particles are in direct contact with the organic functional layer of the one or more OLED cells and the spacer particles do not electrically isolate sections of the organic functional layer from each other; a sealing region abutting an outer vertical surface of the sealing dam; and an adhesive located in the sealing region, the adhesive hermetically sealing the cell region.
