[0031] The electronic device housing and the electronic device according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Refer to Figure 1 As shown, the electronic device housing according to the embodiments of the present invention includes a substrate layer 10 and a bright silver layer.

[0033] Specifically, the substrate layer 10 can be configured with patterns. The bright silver layer includes an underlayer 20, an optical brightening layer 30 and a non-conductive metal brightening layer 40. Among them, the underlayer 20 is formed on the substrate layer 10; the optical brightening layer 30 is formed on the underlayer 20, and the optical brightening layer 30 is made of niobium oxide and / or silicon dioxide materials. The non-conductive metal brightening layer 40 is formed on the optical brightening layer 30, and the non-conductive metal brightening layer 40 is made of indium and / or indium tin alloy materials.

[0034] In the above bright silver layer, the optical brightening layer 30 uses niobium oxide and / or silicon dioxide materials. Niobium oxide can be niobium pentoxide, which has a high refractive index. Silicon dioxide is an inorganic substance with the chemical formula SiO2. Silicon atoms and oxygen atoms are arranged in a long-range order to form a crystal state. It is a hard, brittle, insoluble, colorless and transparent solid, and is commonly used in the manufacture of optical instruments, etc. In this application, niobium oxide is used as the optical brightening layer 30, which has a refraction effect. By using the refraction effect, the image of the substrate layer 10 can be seen, and the bright white effect can be improved.

[0035] In the above-mentioned bright silver layer, the non-conductive metal brightening layer 40 is made of indium and / or indium-tin alloy material. Indium is a soft silver-gray metal with luster. Tin is a main group metal with a silver-gray metallic luster and good stretchability. The silver-gray luster of indium and tin can enhance the whitening effect.

[0036] It should be noted that, according to the test, if a single non-conductive metal brightening layer 40 is used for brightening, the brightening effect is relatively poor, and the image color observed at different viewing angles is single. In the present application, the optical brightening layer 30 is combined with the non-conductive metal brightening layer 40 to significantly improve the brightening effect, and the refractive index of the optical brightening layer 30 can make the pattern color observed at different viewing angles richer and more brilliant.

[0037] In the electronic device housing, the total thickness of the substrate layer 10 and the bright silver layer can be configured as needed, and the thickness of each layer in the bright silver layer can also be adjusted as needed. For example, the thickness can be adjusted according to the refractive index requirements. For example, the total thickness of the substrate layer 10 and the bright silver layer can be between 160nm and 180nm.

[0038] According to an embodiment of the present invention, the electronic device housing has a bright silver layer, which includes a base layer 20, an optical brightening layer 30 and a non-conductive metal brightening layer 40, wherein the optical brightening layer 30 and the non-conductive metal brightening layer 40 both have a brightening effect, and the optical brightening layer 30 can significantly improve the brightening effect. In addition, the refractive index of the optical brightening layer 30 can be used to form different colors and pattern changes under different viewing angles.

[0039] In one embodiment of the present invention, a protective layer 60 is further included. The protective layer 60 is formed on the non-conductive metal brightness enhancement layer 40 and is made of niobium oxide and / or titanium oxide.

[0040] That is to say, the protective layer 60 is located on the surface of the non-conductive metal brightening layer 40. On the one hand, the protective layer 60 can isolate and protect the non-conductive metal brightening layer 40. On the other hand, since niobium oxide is colorless and transparent and titanium oxide is white, the visual brightening effect can be improved.

[0041] In one embodiment of the present invention, a transition layer 50 is provided between the non-conductive metal brightening layer 40 and the optical brightening layer 30. The transition layer 50 is made of silicon material. Silicon is a semiconductor material with high hardness. The transition layer 50 is provided between the non-conductive metal brightening layer 40 and the optical brightening layer 30, which can make the bonding force between the non-conductive metal brightening layer 40 and the optical brightening layer 30 stronger and at the same time, can also make the light transmittance transition smoothly.

[0042] In some embodiments of the present invention, the optical brightening layer 30 includes a first optical brightening layer 301 and a second optical brightening layer 302. The first optical brightening layer 301 is formed on the underlying layer 20, the second optical brightening layer 302 is formed on the first optical brightening layer 301, and the refractive index of the second optical brightening layer 302 is lower than that of the first optical brightening layer 301. Exemplarily, the first optical brightening layer 301 is made of niobium oxide material, and the second optical brightening layer 302 is made of silicon dioxide material.

[0043] In this embodiment, the optical brightening layer 30 includes a first optical brightening layer 301 and a second optical brightening layer 302. The refractive indices of the first optical brightening layer 301 and the second optical brightening layer 302 are different. Thus, different refractive indices can be used to present different color image effects at different viewing angles.

[0044] It can be understood that the number of layers of the optical brightening layer 30 is not limited to one or two layers, and can also be a multi-layer structure of more than two layers. The thicknesses of different layers can be different, so that the refractive indices of each layer are different, and thus the electronic device housing can achieve different color changes at different angles.

[0045] In an embodiment of the present invention, the protective layer 60 includes a first protective layer 601 and a second protective layer 602. The first protective layer 601 is formed on the non-conductive metal brightening layer 40, and the first protective layer 601 is made of niobium oxide material. The second protective layer 602 is formed on the first protective layer 601, and the second protective layer 602 is made of titanium oxide material.

[0046] That is to say, in this embodiment, the protective layer 60 is mainly composed of a first protective layer 601 and a second protective layer 602. Among them, the first protective layer 601 uses niobium oxide material, and the second protective layer 602 uses titanium oxide material. Thus, niobium oxide and titanium oxide can be used to play a role in protection and improving bright white. In addition, the titanium oxide material can improve the adhesion of the ink layer on its surface.

[0047] Optionally, the underlying layer 20 is one or several materials selected from silicon, zirconium oxide, and titanium oxide.

[0048] In an embodiment of the present invention, the underlying layer 20 includes a first underlying layer 201 and a second underlying layer 201. The first underlying layer 201 is formed on the substrate layer 10, and the first underlying layer 201 is zirconium oxide. The second underlying layer 201 is formed on the first underlying layer 201, and the second underlying layer 201 is made of titanium oxide material.

[0049] That is to say, in this embodiment, the base layer 20 is mainly composed of a first base layer 201 and a second base layer 201. The first base layer 201 is made of zirconium oxide material, and the second base layer 201 is made of titanium oxide material. Zirconium oxide has a mesh structure and has good adhesion, while titanium oxide can eliminate the stress on the surface of zirconium oxide and further improve the adhesion.

[0050] Optionally, the substrate layer 10 includes a base layer, a UV layer and a color pattern layer arranged in sequence, the base layer 20 is formed on the color pattern layer, the base layer is generally made of plastic, and the color pattern layer can be configured into different color patterns as needed, so that the electronic device housing can present a gorgeous color pattern.

[0051] In one embodiment of the present invention, the base layer 20 and the optical brightening layer 30 are formed by vacuum coating under a first vacuum environment, and the non-conductive metal brightening layer 40 and the protective layer 60 are formed by vacuum coating under a second vacuum environment, wherein the first vacuum environment is a vacuum environment filled with oxygen and an inert gas, and the second vacuum environment is a vacuum environment filled with an inert gas and does not contain oxygen, and the inert gas may be argon or the like.

[0052] In this way, by using the first vacuum environment and the second vacuum environment, the vacuum coating process can be conveniently used to realize the formation of the base layer 20, the optical brightening layer 30, the non-conductive metal brightening layer 40 and the protective layer 60. In addition, in the second vacuum environment, problems such as oxidation of the non-conductive metal brightening layer 40 can be prevented.

[0053] In addition, it can be understood that the electronic device housing can be the shell of the electronic device itself, or can be a protective shell mounted on the outside of the electronic device.

[0054] An electronic device according to an embodiment of the present invention has the electronic device housing as described above.

[0055] According to the electronic device provided by the embodiment of the present invention, the electronic device housing has a bright silver layer, and the bright silver layer includes a base layer 20, an optical brightening layer 30 and a non-conductive metal brightening layer 40, wherein the optical brightening layer 30 and the non-conductive metal brightening layer 40 both have a brightening effect, and the optical brightening layer 30 can significantly improve the bright white effect. In addition, the refractive index of the optical brightening layer 30 can be used to form different color and pattern changes under different viewing angles.
