All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The housing provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 4, an embodiment of the present application discloses a housing, which includes a first film 110 and a transparent substrate 200.

The transparent substrate 200 may be made of glass or a transparent polymer material. The first film 110 is disposed on the transparent substrate 200. Specifically, the first film 110 may be disposed on a side of the transparent substrate 200 facing the inside of the electronic device, that is, a side facing the electronic component. The first film 110 includes a first texture layer 111, an evanescent layer 112 and a fluorescent ink layer 113, and the transparent substrate 200, the first texture layer 111, the evanescent layer 112 and the fluorescent ink layer 113 may be sequentially stacked.

The first texture layer 111 can texture the shell, further increasing the degree of gloss variation of the shell. The texture shape of the first texture layer 111 may be various, and the embodiment does not limit the specific shape of the texture. Of course, the first texture layer 111 should not affect the incidence of light. In one particular embodiment, the first texture layer 111 may be a transfer UV (i.e., radiation cured) texture layer.

The fluorescent ink layer 113 determines the overall color of the housing. The transmittance of the evanescent layer 112 decreases gradually along a first direction, which is parallel to the plane of the transparent substrate 200. The first direction may be a longitudinal direction or a width direction of the transparent substrate 200, or may be a diagonal direction of the outer shape of the transparent substrate 200.

In the embodiment disclosed in this application, the luminousness of fading layer 112 reduces gradually, consequently along the direction that the luminousness of fading layer 112 reduces, fading layer 112 strengthens the effect of sheltering from of light, and the user can see the colour of fluorescence ink layer 113 by the change of depth to light to realized the gradual change effect of casing, the gloss that its presented changes abundantly more, thereby makes the casing have stronger visual impact, thereby improves the outward appearance feel of casing.

In the above embodiment, as shown in fig. 2, the light shielding effect of the evanescent layer 112 is enhanced, and at this time, the evanescent layer 112 gradually changes from transparent (shown by the black portion in fig. 2) to opaque (shown by the white portion in fig. 2). At this time, in the case of light transmission, the user can see the color of the fluorescent ink layer 113 through the fading layer 112, and since the light transmittance is gradually reduced, the color of the fluorescent ink layer 113 seen by the user gradually becomes lighter and lighter, so that the user is finally in a light-tight state directly, and the user cannot see the color of the fluorescent ink layer 113, but can only see the color represented by the fading layer 112.

In the embodiment of the present application, the fluorescent ink layer 113 can improve the color brightness of the whole casing, and the user can see the casing with fluorescent color, so as to further improve the texture of the casing.

In addition, the transmittance of the evanescent layer 112 gradually decreases, so that the evanescent layer 112 gradually changes from transparent to opaque. The fluorescent color can be seen in the transparent part, and the color represented by the evanescent layer 112 is seen in the opaque part, so that a gradual change effect from the common optical color to the fluorescent color is formed.

In the embodiment disclosed in the present application, the first film 110 is disposed on the transparent substrate 200, and since the first film 110 can generate a gradual change effect, the gradual change position of the first film 110 can be disposed at the joint of the different transparent substrates 200 of the housing, so as to reduce the visual split feeling caused by the joint between the transparent substrates 200, thereby enhancing the integral feeling of the housing of the electronic device.

In the above embodiment, the color of the fluorescent ink layer 113 may be orange, and may also be other colors, which is not limited herein.

In the above embodiment, the opaque portion of the evanescent layer 112 is specularly reflected and may have a luminance greater than or equal to 78 cd/m.

In another alternative embodiment, the thickness of the evanescent layer 112 along the first direction can be gradually increased, and at this time, since the thickness of the evanescent layer 112 is gradually increased, light is difficult to enter the fluorescent ink layer 113, so that it is difficult for a user to see the fluorescent ink layer 113 below the evanescent layer 112, thereby achieving a color gradient effect. In this embodiment, the light transmittance of the evanescent layer 112 is controlled by changing the thickness thereof, so that the structure and the manufacturing process of the first film 110 are both simple.

As shown in fig. 3, in a specific manufacturing process of the first film 110, a base layer of the first film 110 is placed in a magnetron sputtering apparatus, plasma is generated in the magnetron sputtering apparatus, and the plasma bombards a target 310 in the magnetron sputtering apparatus, so that target atoms are sputtered from the target 310, and the target atoms are attached to the base layer of the first film 110, thereby forming the evanescent layer 112. In order to increase the thickness of the evanescent layer 112 deposited on the base layer of the first membrane 110, a baffle 320 is disposed in the magnetron sputtering apparatus, the baffle 320 is disposed between the target 310 and the base layer of the first membrane 110, the larger the thickness of the baffle 320 is, the smaller the thickness of the evanescent layer 112 deposited on the base layer of the first membrane 110 is, and thus the thickness of the baffle 320 is gradually reduced along the first direction, because the smaller the thickness of the baffle 320 is, the larger the thickness of the evanescent layer 112 deposited on the base layer of the first membrane 110 is.

The base layer of the first film 110 may be the first explosion-proof layer 114, or may be other transparent layers, which is not limited herein.

Further, the optical coating layer 121 may have a three-layer structure in which the first and third layers are titanium oxide and the second layer is silicon oxide. The optical coating layers 121 with a certain number of layers and thickness are deposited on the surface of the base layer of the second diaphragm 120, so that the shell has strong metal reflection texture, and appearance texture of the shell is improved. The base layer of the second film 120 may be the second explosion-proof layer 123, which is described below, or may be other transparent layers, which is not limited herein.

Of course, the optical coating layer 121 is only an example, and when implementing the embodiment of the present application, another optical coating layer 121, for example, a metal film of a reddish phase, a metal film of a greenish phase, or another metal film, may be provided according to practical situations, which is not limited in the embodiment of the present application. In addition, besides the optical coating layer 121, other optical coating layers 121 may be adopted by those skilled in the art according to actual needs, and the embodiment of the present application is not limited thereto.
