Abstract

A housing is provided, the housing includes a housing substrate and at least one double-sided composite texture film located on one side of an inner surface of the housing substrate. The double-sided composite texture film includes a first substrate, a first texture layer located on a first surface of the first substrate, and a second texture layer located on a second surface of the first substrate. The first surface of the first substrate is close to the housing substrate, and the second surface is away from the housing substrate. The first texture layer has a first texture pattern that includes a plurality of grooves and a plurality of bosses. The second texture layer has a second texture pattern that includes a plurality of grooves and a plurality of bosses.

First claim

What is claimed is:

a first substrate,
a first texture layer disposed on a first surface of the first substrate, and
a second texture layer disposed on a second surface of the first substrate, wherein
the first surface of the first substrate is close to the housing substrate and the second surface is away from the housing substrate,
each of the first texture layer and the second texture layer comprises a plurality of grooves and a plurality of bosses;
wherein the housing substrate is a hardened layer;
a material that forms the first substrate comprises polyethylene terephthalate or a thermoplastic polyurethane elastomer;
the housing further comprises an ink layer, a glossy oil buffer layer, an adhesive layer, and an injection molding layer that are sequentially away from the housing substrate, and the double-sided composite texture film is located between the ink layer and the housing substrate; and
the first texture layer closest to the hardened layer is in direct contact with the hardened layer within the housing.

2. The housing according to claim 1 , wherein the housing further comprises a single-sided composite texture film disposed on the first side of the inner surface of the housing substrate and disposed with the double-sided composite texture film in a stacked manner,
wherein the single-sided composite texture film comprises a second substrate and a third texture layer disposed on a surface of the second substrate, and
wherein the third texture layer comprises a plurality of grooves and a plurality of bosses.

3. The housing according to claim 1 , wherein the inner surface of the housing substrate comprises a plurality of grooves and a plurality of bosses; and
wherein the housing further comprises a first bonding layer disposed on the inner surface of the housing substrate, and a refractive index of the first bonding layer is different from a refractive index of the housing substrate.

4. The housing according to claim 2 , wherein the inner surface of the housing substrate comprises a plurality of grooves and a plurality of bosses; and
wherein the housing further comprises a first bonding layer disposed on the inner surface of the housing substrate, and a refractive index of the first bonding layer is different from a refractive index of the housing substrate.

5. The housing according to claim 1 , wherein an outer surface of the housing substrate comprises a plurality of grooves and a plurality of bosses.

6. The housing according to claim 3 , wherein an outer surface of the housing substrate comprises a plurality of grooves and a plurality of bosses.

7. The housing according to claim 1 , wherein the housing further comprises a second substrate disposed between the housing substrate and the double-sided composite texture film.

8. The housing according to claim 1 , wherein the housing substrate is a hardened layer;
the first substrate is a composite plate that comprises at least a polycarbonate film substrate and a polymethacrylate substrate that are disposed in a stacked manner; and
