Abstract

A method of making an OLED device includes the steps of: providing a curved, rigid substrate; and forming one or more OLED elements on the substrate.

Claims

1. An OLED device comprising:

a) a curved, rigid substrate; and

b) one or more OLED elements formed on the substrate.

2. The OLED device claimed in claim 1, wherein the curved substrate defines a cylindrical curve.

3. The OLED device claimed in claim 1, wherein the OLED device is a display and the one or more OLED elements are pixels.

4. The OLED device claimed in claim 3, wherein the OLED device is a panoramic display.

5. The OLED device claimed in claim 4, wherein the panoramic display is a desktop display.

6. The OLED device claimed in claim 3, wherein the panoramic display is a computer monitor.

7. The OLED device claimed in claim 1, wherein the OLED device is an area illumination light source.

8. The OLED device claimed in claim 3, wherein the OLED device is a passive-matrix display device.

9. The OLED device claimed in claim 3, wherein the OLED device is an active matrix display device.

10. The OLED device claimed in claim 1, wherein the OLED device is bottom-emitter device.

11. The OLED device claimed in claim 1, wherein the OLED device is top-emitter device.

12. The OLED device claimed in claim 1, wherein the OLED element(s) are located on the inside of the curve.

13. The OLED device claimed in claim 1, wherein the OLED element(s) are located on the outside of the curve.

14. A method of making an OLED device, comprising the steps of:

a) providing a curved, rigid substrate; and

b) forming one or more OLED elements on the substrate.

15. The method claimed in claim 14, wherein the step of forming the OLED element(s) includes evaporation of material from a source.

16. The method claimed in claim 14, wherein the step of forming the OLED element(s) includes depositing material with a stream of compressed fluid.

17. The method claimed in claim 14, wherein the step of forming the OLED element(s) includes depositing material using thermal sublimation from a donor.

18. The method claimed in claim 14, wherein the step of forming the OLED element(s) includes depositing material using an inkjet print head.

19. The method claimed in claim 14, wherein the OLED element(s) are formed on the inside of the curved substrate through a mask held in compression against the substrate.

20. The method claimed in claim 14, wherein the OLED element(s) are formed on the outside of the curved substrate through a mask held in tension against the substrate.

21. The method claimed in claim 15, wherein the curved substrate has a cylindrical curve, the source is a linear source, and the linear source is moved relative to the substrate parallel to an axis of the cylindrical curve.

22. The method claimed in claim 21, wherein the cylindrical curve is circular.

23. The method claimed in claim 22, wherein the OLED element(s) are formed on the inside of the circular cylindrical curve and the linear source rotated with respect to the substrate about the cylindrical axis.

24. The method claimed in claim 22, wherein the OLED element(s) are formed on the outside of the circular cylindrical curve and the substrate is rotated with respect to the linear source about the cylindrical axis.
