Abstract
A substrate support rim used in the fabrication of devices such as organic light emissive diodes (OLEDs) is disclosed. The support rim, which is located at the edge of a substrate, serves to reinforce the substrate, facilitating handling during and after the fabrication process to reduce damage to the device. The support rim comprises, for example, epoxy, adhesives or other materials that adhere to the substrate.
Claims65
A method for reinforcing a substrate on which an OLED device is formed comprising:
- providing a substrate with two major surfaces and one or more sides;
- forming a support rim on at least one of the two major surfaces at an edge adjacent to at least one of the one or more sides, the support rim comprising a resin material;
- and
- processing the substrate by forming an organic layer between two conductive layers on the substrate to complete the OLED device.
A method for reinforcing a substrate on which an OLED device is formed comprising:
- providing a substrate comprised of silicate glass or sodalime glass;
- forming a support rim on an edge of at least one major surface of the substrate, wherein the support rim comprises a material selected from the group consisting of adhesives, epoxy resins, acrylate, polyimide, polyamide, silicon resins, novalak resins and dry resins;
- and
- processing the substrate by forming an organic layer between two conductive layers on the substrate to complete the OLED device.
A method for reinforcing a substrate on which an OLED device is formed comprising:
- providing a substrate with two major surfaces and one or more sides;
- forming a support rim on an edge of at least one major surface of the substrate, where the support rim is on at least one of the one or more sides of the substrate;
- and
- processing the substrate by forming an organic layer between two conductive layers on the substrate to complete the OLED device.
