Abstract

A cover for a display screen is described. The cover for a display screen comprises a transparent substrate, a light transmission enhancing coating formed on the substrate, and a metallic coating formed on the light transmission enhancing coating. An electronic device by having the cover for a display screen is also described.

Claims

1. A cover for a display screen, comprising:

a transparent substrate;

a light transmission enhancing coating formed on the substrate; and

a metallic coating formed on the light transmission enhancing coating.

2. The cover for a display screen as claimed in claim 1, wherein the light transmission enhancing coating is a silicon dioxide film or a titanium dioxide film having a thickness of about 50-100 nm.

3. The cover for a display screen as claimed in claim 1, wherein the metallic coating is an indium coating, a tin coating, or an aluminum silicon coating formed by vacuum deposition.

4. The cover for a display screen as claimed in claim 3, wherein the metallic coating may have a thickness of about 50-150 nm.

5. The cover for a display screen as claimed in claim 1, wherein the cover for a display screen further includes a base coating formed between the substrate and the light transmission enhancing coating.

6. The cover for a display screen as claimed in claim 5, wherein the base coating is a transparent ultraviolet curable paint coating having a thickness of about 6-12 μ

m.

7. The cover for a display screen as claimed in claim 1, wherein the cover for a display screen further includes a top coating formed on the metallic coating, the top coating is a transparent ultraviolet curable paint coating having a thickness of about 8-15 μ

m.

8. The cover for a display screen as claimed in claim 1, wherein the substrate is made of transparent plastic selected from a group consisting of polypropylene, polyamide, polycarbonate, polymethyl methacrylate, and polyethylene terephthalate.

9. The cover for a display screen as claimed in claim 1, wherein the substrate is made of glass.

10. An electronic device, comprising:

a main body, the main body including a display; and

a cover for a display screen, the cover for a display screen being positioned over the display;

wherein the cover for a display screen includes a transparent substrate, a light transmission enhancing coating formed on the substrate, and a metallic coating formed on the light transmission enhancing coating;

the display emit light, and the light transmits through the transparent substrate, the light transmission enhancing coating and the metallic coating.

11. The electronic device as claimed in claim 10, wherein the light transmission enhancing coating is a silicon dioxide film or a titanium dioxide film having a thickness of about 50-100 nm.

12. The electronic device as claimed in claim 10, wherein the metallic coating is an indium coating, a tin coating, or an aluminum silicon coating formed by vacuum deposition.

13. The electronic device as claimed in claim 12, wherein the metallic coating may have a thickness of about 50-150 nm.

14. The electronic device as claimed in claim 10, wherein the cover for a display screen further includes a base coating formed between the substrate and the light transmission enhancing coating.

15. The electronic device as claimed in claim 14, wherein the base coating is a transparent ultraviolet curable paint coating having a thickness of about 6-12 μ

m.

16. The electronic device as claimed in claim 10, wherein the cover for a display screen further includes a top coating formed on the metallic coating, the top coating is a transparent ultraviolet curable paint coating having a thickness of about 8-15 μ

m.

17. The electronic device as claimed in claim 10, wherein the substrate of the cover for a display screen is made of transparent plastic selected from a group consisting of polypropylene, polyamide, polycarbonate, polymethyl methacrylate, and polyethylene terephthalate.
