Flexible protective housing for electronic devices
A flexible housing for a flexible electronic device is coupled to a cover lens for enclosing components disposed between the flexible housing and the cover lens. The flexible housing includes a flexible polymer substrate. A first metal layer covering at least a portion of the flexible polymer substrate. A second metal layer is disposed on the first metal layer. A protective coating covers the second metal layer.
1. A flexible electronic device, comprising:
a flexible housing having a recessed region in which to receive components of the flexible electronic device, the flexible housing comprising:
a flexible polymer substrate having a first surface and one or more side surfaces forming the recessed region, and a second surface opposite the first surface;
a first metal layer disposed on at least a portion of the second surface of the flexible polymer substrate;
a second metal layer disposed on the first metal layer; and
a protective coating disposed on the second metal layer; and
a flexible cover lens positioned over the recessed region and coupled to the flexible housing.
2. The flexible electronic device of claim 1 , wherein the flexible polymer substrate comprises a flexible thermoplastic elastomer (TPE) substrate.
3. The flexible electronic device of claim 2 , wherein the flexible TPE substrate comprises one of: a styrenic block copolymer, a thermoplastic olefin, an elastomeric alloy, a thermoplastic polyurethane, a thermoplastic copolyester, a thermoplastic polyamide, or a silicone material.
4. The flexible electronic device of claim 1 , wherein the flexible polymer substrate includes a laser direct structuring (LDS) additive material.
5. The flexible electronic device of claim 1 , further comprising a promoting layer disposed on the flexible polymer substrate, wherein the first metal layer is disposed on the promoting layer.
6. The flexible electronic device of claim 1 , further comprising a transitional material layer disposed on the second metal layer and positioned between the second metal layer and the protective coating.
7. The flexible display device of claim 1 , wherein the first metal layer comprises one of: copper and nickel, and the second metal layer comprises one of: nanocrystalline cobalt, aluminum, gold, silver, platinum, or palladium.
8. The flexible display device of claim 1 , further comprising a transitional material layer disposed on the second metal layer and positioned between the second metal layer and the protective coating, the transitional material layer comprising a metal oxide material or a metal nitride material, and the protective coating comprises an anti-fingerprint (AFP) material.
9. The flexible display device of claim 8 , further comprising a primer material layer disposed between the transitional material layer and the protective coating.
10. The flexible display device of claim 1 , wherein the one or more side surfaces contact the flexible cover lens.
11. A flexible electronic device, comprising:
a flexible housing, comprising:
a flexible polymer substrate having a first surface at least partially forming a recessed region and a second surface opposing the first surface;
a first metal layer covering at least a portion of the second surface of the flexible polymer substrate;
a second metal layer disposed on the first metal layer; and
a protective coating covering the second metal layer.
12. The flexible electronic device of claim 11 , wherein the flexible polymer substrate comprises a flexible thermoplastic elastomer (TPE) substrate and a laser direct structuring (LDS) additive material blended with the TPE substrate.
13. The flexible electronic device of claim 11 , wherein the first metal layer comprises one of: copper or nickel and the second metal layer comprises one of: nanocrystalline cobalt, aluminum, gold, silver, platinum, or palladium.
14. The flexible electronic device of claim 11 , further comprising a transitional material layer disposed on the second metal layer and positioned between the second metal layer and the protective coating.
15. The flexible electronic device of claim 14 , further comprising a primer material layer disposed between the transitional material layer and the protective coating.
16. The flexible electronic device of claim 11 , wherein the recessed region is configured to receive components of the flexible electronic device, the flexible electronic device further comprising a flexible cover lens positioned over the recessed region and coupled to the flexible housing.
