Ornamental display device
View Patent ↗An ornamental display device having an interferometric modulator for displaying an ornamental image. The ornamental device may have a patterned diffuser formed on a transparent substrate to provide an ornamental image or information. The ornamental device may also be a piece of jewelry or an article that may be worn. The image displayed may have an iridescent appearance. A controller may also be used to control images displayed on multiple ornamental device to provide coordinated images based on externals received or pre-programmed images.
1. A method of forming a display device, comprising:
providing an interferometric modulator comprising a transparent substrate, a partially reflective layer and a substantially reflective layer spaced apart and separated from the partially reflective layer by a cavity; and
covering the substrate with a diffuser, wherein the diffuser is patterned to provide information.
2. The method of claim 1 , wherein the information comprises a logo.
3. The method of claim 1 , wherein the partially reflective layer and the diffuser are on opposite sides of the transparent substrate.
4. The method of claim 1 , wherein covering the substrate with the diffuser comprises attaching the diffuser to the substrate using an adhesive.
5. The method of claim 1 , further comprising attaching the diffuser to the transparent substrate prior to fabrication of the interferometric modulator.
6. The method of claim 1 , wherein the diffuser is formed on the transparent substrate by spin-coating.
7. The method of claim 1 , further comprising providing an attachment means on the display device whereby the display device is configured to be worn.
8. The method of claim 1 , wherein the display device is configured as jewelry.
9. A display device, comprising:
a transparent substrate;
a first surface for reflecting light on the substrate;
a second surface for reflecting light, the second surface being substantially parallel to the first surface, wherein the second surface is separated from the first surface; and
a patterned diffuser on the substrate, wherein the diffuser is patterned to provide information.
10. The display device of claim 9 , wherein the information comprises a logo.
11. The display device of claim 9 , wherein the diffuser has a varied thickness.
12. The display device of claim 9 , wherein the diffuser comprises a polymer film.
13. The display device of claim 9 , wherein the diffuser film is about 50-100 μm thick.
14. A display device, comprising:
means for transmitting light;
a first reflecting means on the light transmitting means;
a second reflecting means substantially parallel to the first reflecting means, wherein the second reflecting means is separated from the first reflecting means; and
means for diffusing light on a second side of the transmitting means, wherein the diffusing means is patterned to provide information.
15. The display device of claim 14 , wherein the information comprises a logo.
16. The display device of claim 14 , wherein the first reflecting means comprises a first reflective layer and the second reflecting means comprises a second reflective layer.
17. The display device of claim 14 , wherein the means for transmitting light comprises a transparent substrate.
18. The display device of claim 14 , wherein the diffusing means comprises a diffuser film.
19. The display device of claim 14 , wherein the diffusing means has a varied thickness.
20. The display device of claim 14 , wherein the diffusing means comprises a polymer film.
21. The display device of claim 14 , wherein the diffusing means is about 50-100 μm thick.
