Abstract
An organic light-emitting device comprising a transparent cover sheet; a region of organic light-emitting material behind the cover sheet; a region of circuitry behind the cover sheet for regulating the flow of current to the organic light-emitting material; and a non-light-transmissive layer which lies between the cover sheet and the circuitry.
Claims23
An organic light-emitting device comprising:
- a transparent cover sheet, which covers a viewing surface of said device;
- at least one region of organic light-emitting material behind the cover sheet;
- a region of circuitry behind the cover sheet for regulating the flow of current to the organic light-emitting material;
- and
- a non-light-transmissive layer which lies between the cover sheet and the circuitry, wherein the non-light-transmissive layer is adjacent to the cover sheet.

A method for forming an organic light-emitting device, comprising the steps of:
- depositing a region of a non-light-transmissive layer over a transparent cover sheet, which covers a viewing surface of said device;
- depositing a region of organic light-emitting material over an area of the transparent cover sheet that is not covered by the non-light-transmissive layer;
- depositing over the non-light-transmissive layer a region of circuitry for regulating the flow of current to the organic light-emitting material, wherein the non-light-transmissive layer is adjacent to the cover sheet.
An organic light-emitting device comprising:
- a transparent cover sheet, which covers a viewing surface of said device;
- at least two spaced-apart regions of organic light-emitting material behind the cover sheet;
- a region of circuitry comprising thin film transistors behind the cover sheet for regulating the flow of current to the organic light-emitting material;
- and,
- a non-light-transmissive separating region separating the regions of organic light-emitting material, wherein the non-light-transmissive separating region is adjacent to the cover sheet.
