Abstract

An optical device includes a colored reflector layer having a first surface, a second surface opposite the first surface, and a third surface; and a selective light modulator layer external to the first surface of the colored reflector layer. A method of making an optical device is also disclosed.

First claim

What is claimed is:

1 . An optical device, comprising:
a colored reflector layer having a first surface, a second surface opposite the first surface; and a third surface; and a selective light modulator layer external to the first surface of the colored reflector layer.

2 . The optical device of claim 1 , wherein the colored reflector layer includes a colored metal, colored metal alloys, colored non-metals, and metals chemically converted into a colored compound.

3 . The optical device of claim 1 , wherein the colored reflector layer is a colored metal chosen from copper, gold, and bronzes.

4 . The optical device of claim 2 , wherein the metals that are chemically converted into a colored compound include aluminum and stainless steel.

5 . The optical device of claim 1 , wherein the colored reflector layer includes colored non-metals.

6 . The optical device of claim 5 , wherein the colored non-metals include polyacetylene and organic materials.

7 . The optical device of claim 1 , wherein the colored reflector layer does not include aluminum or a white-colored material.

8 . The optical device of claim 1 , wherein the colored reflector layer is a first color and the selective light modulator layer is a second color different from the first color.

9 . The optical device of claim 1 , wherein the colored reflector layer is a first color and the selective light modulator layer is a second color the same as the first color.

10 . The optical device of claim 1 , wherein the selective light modulator layer is a first selective light modulator layer; and further including a second selective light modulator layer external to the second surface of the colored reflector layer.

11 . A method of making an optical device, comprising:
depositing a colored reflector layer on a substrate; and depositing a selective light modulator layer onto the colored reflector layer using a liquid coating process.

12 . The method of claim 11 , wherein the selective light modulator layer is a first selective light modulator layer, and further comprising depositing a second selective light modulator layer between the substrate and the colored reflector layer.

13 . The method of claim 11 , wherein the colored reflector layer is not subjected to passivation.

14 . The method of claim 11 , wherein the colored reflector layer improves a color attribute of the selective light modulator layer.

15 . The method of claim 11 , wherein the colored reflector layer controls gassing.

16 . The method of claim 11 , wherein the colored reflector layer is deposited using a physical vapor deposition process.

17 . The method of claim 11 , wherein the colored reflector layer includes a colored metal, colored metal alloys, colored non-metals, and metals chemically converted into a colored compound.

18 . The method of claim 11 , wherein the colored reflector layer is a colored metal chosen from copper, gold, and bronzes.

19 . The method of claim 17 , wherein the metals that are chemically converted into a colored compound include aluminum and stainless steel.

20 . The method of claim 11 , wherein the colored reflector layer includes a colored non-metal including polyacetylene and organic materials.
