Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, in an embodiment, an electronic device includes a housing 100 and a functional device 200. The housing 100 defines an accommodating space 100a, the functional device 200 is disposed in the accommodating space 100a, and the housing 100 can protect the functional device 200 (e.g., a motherboard, a battery, etc.).

Specifically, the electronic device may be a mobile phone, a tablet computer, a notebook computer, an intelligent bracelet, an intelligent watch, and the like, and the housing 100 may be a front shell, a frame, a rear cover, and the like of the electronic device without limitation.

Referring to fig. 2, in an embodiment, the casing 100 may include a base 10 and an effect film 20 disposed on the base 10, wherein the effect film 20 may be disposed on any side of the base 10 as required, so that the casing 100 can present a certain color and gloss.

The material of the substrate 10 may be glass, plastic, or a composite material of glass, plastic, metal, ceramic, or the like. When the substrate 10 is made of plastic, it may be a composite board of polymethyl methacrylate (PMMA) and Polycarbonate (PC), and specifically, the PC and PMMA plastic particles may be co-extruded to form a composite board of a PC layer and a PMMA layer.

The total thickness of the substrate 10 may be 500-1000 μm, such as 500 μm, 640 μm, 700 μm, 800 μm, 900 μm, 1000 μm, etc. The thickness of the PMMA layer can be 40-55 μm, the PMMA layer with the thickness can meet the wear-resisting requirement of the shell 100, and meanwhile, the probability of cracking in the high-pressure forming treatment process of the matrix 10 in the production process and under the conditions of electronic equipment falling and the like can be reduced. Specifically, the thickness of PMMA may be 40 μm, 45 μm, 50 μm, 55 μm, etc., and is not particularly limited herein.

In the present embodiment, the substrate 10 is first produced by co-extrusion, and then the case 100 is further produced by bonding the effect film 20 to one side of the obtained substrate 10. In other embodiments, the housing 100 may be obtained by injection molding the base 10 on one side of the effect membrane 20 by means of in-mold injection molding.

Further, the effect film 20 may include a reflective layer 11 and a liquid crystal optical film layer 12. The position relationship between the reflective layer 11 and the liquid crystal optical film layer 12 may be that the reflective layer 11 is located between the substrate 10 and the liquid crystal optical film layer 12, or that the liquid crystal optical film layer 12 is located between the reflective layer 11 and the substrate 10, which is not limited herein.

The reflective layer 11 may be used to reflect incident light, so as to improve the brightness and the glossiness of the casing 100, and make the casing 100 exhibit a high brightness effect.

In the present embodiment, the material of the reflective layer 11 may be at least one of zirconia, titania, silica, and niobium oxide. The reflective layer 11 may be formed by directly or indirectly plating the reflective layer 11 material on the substrate 10 using an electron gun. In the actual production process, the reflective layer 11 may be composed of one or more layers, and a 3-5-layer film structure formed by combining two or more of zirconia, titania, silica and niobia, for example, a 3-layer film structure of titania + silica + titania, or a 4-layer film structure of zirconia + niobium pentoxide + silica + niobium pentoxide, or a 5-layer film structure of titania + silica + titania, and the like, and is not limited herein.

Further, the thickness of the reflective layer 11 may be not less than 160nm, and specifically may be set to 160-400nm, such as 160nm, 200nm, 250nm, 300nm, 350nm, 400nm, etc., as required, which is not limited herein.

It should be noted that, in the present embodiment, the thickness of the reflective layer 11 is relatively thick, and the wavelength band of the reflected light is relatively wide, which can be 200-300nm, and the reflectivity is as high as 40% or more, compared with the reflective layer 11 with relatively thin thickness. In an application scenario, when the thickness of the reflective layer 11 is 200nm, the reflectance curve obtained by the detection of the spectrometer is shown in fig. 3; the reflectance curve obtained by spectrometer inspection of the reflective layer 11 with a thickness of 350nm is shown in fig. 4. As can be seen, the reflectivity of the reflective layer 11 is as high as 60% -75% at both thicknesses. The reflective layer 11 in the present embodiment has a high reflectance, and can improve the brightness and the glossiness of the housing 100.

It should be noted that, after the light enters the reflective layer 11 in this embodiment, the light is reflected and refracted by each film structure of the reflective layer 11, so that the light finally reflected from the reflective layer 11 has a certain hue, such as blue, golden yellow, pink, and the like, and specifically, different colors can be realized by setting film structures with different numbers of layers, different thicknesses, and the like in the production process. In this way, the reflective layer 11 can provide the housing 100 with a high brightness and a certain color, thereby further improving the display effect of the housing 100.

Further, the liquid crystal optical film layer 12 in the present embodiment may be located on the side of the substrate 10 facing the functional device inside the electronic apparatus, or may be located on the side of the substrate 10 away from the functional device inside the electronic apparatus.

Specifically, the liquid crystal optical film layer 12 may contain oriented liquid crystal, and on one hand, incident light entering the liquid crystal optical film layer 12 can be partially reflected by the oriented liquid crystal, so as to improve the brightness and glossiness of the whole casing 100; on the other hand, the oriented liquid crystal reflects light to show a certain main color, and the wavelength of the reflected light is different with the change of the incident angle of the incident light, so that when the observation angle of the user is different, the observed color of the liquid crystal optical film layer 12 can be red-shifted or blue-shifted with the change of the observation angle, thereby the whole casing 100 has a dazzling effect.

The dominant color may refer to a color that the liquid crystal optical film 12 presents when a user observes from a certain fixed angle, for example, perpendicular to the light incident plane of the corresponding liquid crystal optical film 12. In one application scenario, the color presented by the liquid crystal optical film layer 12 may change based on the dominant color as the viewing angle of the user changes.

In the above manner, since the reflective layer 11 is relatively thick and has a relatively high reflectivity, the brightness and the glossiness of the housing 100 can be improved, so that the housing 100 can exhibit a high-brightness dazzling effect in cooperation with the liquid crystal optical film layer 12.

It should be further noted that, since the reflected light of the reflective layer 11 also has a certain hue, the color of the housing 100 can be further enriched by using the liquid crystal optical film layer 12 in combination with the thicker reflective layer 11. In an application scenario, the main color of the liquid crystal optical film layer 12 corresponds to a red color phase with a wavelength of about 600nm, and the reflected light of the reflective layer 11 has a green color phase of 550nm, so that the housing 100 can present the above two complementary colors, and in addition, the color presented by the housing 100 is more gorgeous due to the color effect of the liquid crystal along with the change of the color.

It should be noted that the reflectivity of the housing 100 in this embodiment may be greater than 50%, such as 52%, 54%, 56%, 58%, 60%, etc., which is not limited herein. When the angle between the incident light and the incident surface of the housing 100 is 60 °, the glossiness of the housing 100 may be not less than 150 gloss units, such as 150 gloss units, 170 gloss units, 190 gloss units, 210 gloss units, 230 gloss units, 250 gloss units, and the like, which is not limited herein.

In one embodiment, referring to fig. 5, the liquid crystal optical film 12 may include an alignment layer 122 and a liquid crystal layer 121. The liquid crystal layer 121 may include the aligned liquid crystal.

Specifically, the liquid crystal may be a cholesteric liquid crystal. Cholesteric liquid crystal molecules are flat, can be arranged in parallel to each other to form a layer structure by means of interaction of end groups, long molecular axes in each plane layer are arranged in parallel and are relatively like nematic liquid crystals, and the long molecular axes between the layers gradually deflect to form a spiral shape. In practice, nematic liquid crystals can be converted into cholesteric liquid crystals by adding optically active substances to reflect light having certain characteristic wavelengths.

In this embodiment, the liquid crystal may specifically include a polymerizable monomer, a nematic liquid crystal, a chiral molecule, a photoinitiator, and the like. Wherein, the polymerizable monomer can be acrylate, isobornyl acrylate, tetrahydrofuran acrylate, methacrylate group and the like, and the nematic liquid crystal can be:

the chiral molecule may be:

the photoinitiator can be thioxanthone photoinitiator, (2,4, 6-trimethylbenzoyl) diphenylphosphine oxide, -hydroxycyclohexyl benzophenone, 2-methyl- [4- (methylthio) phenyl ] ketone]-2- (4-morpholinyl) - -, acetone, etc., without limitation.

In some application scenarios, the cholesteric liquid crystal may further include an ultraviolet light absorber, and the like.

Note that, in the present embodiment, the wavelength of the reflected light reflected by the aligned liquid crystal satisfies the following equation: λ is 2np sin θ, where λ is the wavelength of the reflected light, n is the average refractive index of the aligned liquid crystal, p is the pitch of the aligned liquid crystal, and θ is the angle between the incident light and the surface of the liquid crystal layer 121, i.e., the complementary angle of the incident light. Wherein the aligned liquid crystals can be aligned according to the corresponding pitch p. As shown in fig. 6, when the viewing angle of the user is perpendicular to the surface of the liquid crystal layer 121, that is, θ is 90 °, the aligned liquid crystal selectively reflects light having a wavelength λ of 2np, thereby displaying a color displayed by light having a wavelength λ of 2np, that is, a dominant color displayed by the aligned liquid crystal. With the change of the observation angle of the user, the incident angle of the incident light entering the eyes of the user changes, and θ changes, which causes the wavelength λ of the reflected light reflected by the liquid crystal to change accordingly, so as to change the color of the reflected light, and thus when the observation angle of the user changes, the observed color of the liquid crystal layer 121 changes with the change of the observation angle, and red shift or blue shift occurs, thereby causing color change with the angle.

It should be noted that, compared to the reflective layer 11, the reflective band width of the liquid crystal optical film 12 in this embodiment is narrower, which may be 60-100nm, and the reflectivity of light is less than 50%, so that the liquid crystal optical film is more pure and transparent in visual appearance. In an application scenario, a reflectivity curve of the liquid crystal optical film layer 12 detected by a spectrometer is shown in fig. 7, and it can be seen that the liquid crystal optical film layer 12 mainly reflects light with a wavelength around 600nm, and the reflectivity is at most around 50%.

The thickness of the liquid crystal layer 121 may be 2-3 μm, for example, 2 μm, 2.5 μm, 3 μm, and the like, and may be selected according to actual requirements.

Further, an alignment layer 122 may be disposed on one side of the liquid crystal layer 121, and may include an alignment agent for aligning the liquid crystal in the liquid crystal layer 121, so that the liquid crystal in the liquid crystal layer 121 is aligned.

Specifically, the orientation agent can be cinnamic acid modified polyvinyl alcohol, and the structural formula is as follows:

of course, in other embodiments, other alignment agents may be used, and are not limited herein.

In this embodiment, the thickness of the alignment layer 122 may be less than 1 μm, for example, 0.9 μm, 0.8 μm, 0.7 μm, and the like, and may be selected according to actual requirements.

Specifically, when the liquid crystal optical film layer 12 is prepared, a carrier film may be provided, wherein the material of the carrier film may be a polymer material with certain flexibility, such as polyethylene terephthalate (PET), Polyvinyl chloride (PVC), Thermoplastic polyurethane elastomer rubber (TPU), and the like.

Then, an alignment agent is coated on the support film, and alignment treatment is performed to obtain an alignment layer 122. The alignment agent may be a photo-alignment agent, and for example, cinnamic acid-modified polyvinyl alcohol may be used. Specifically, the orientation agent can be dissolved in deionized water at 70-90 ℃ to prepare an aqueous solution with the concentration of 1.2%, and after the preparation is completed, the coating is completed within 72 hours. Before coating the orientation agent, a filter membrane with the thickness of 1 mu m can be used for filtering to remove impurities and particles so as to improve the coating effect. After the filtration is completed, the alignment agent solution may be coated on the support film by means of a dimple coating using a 180-mesh anilox roller. Then drying at 75-100 deg.C, and orienting under 365nm ultraviolet lamp.

Liquid crystal is further coated on the alignment layer 122 so that the liquid crystal is aligned according to the alignment layer 122 to obtain a liquid crystal layer 121, thereby forming a liquid crystal optical film layer 12 on the carrier film. Specifically, a polymerizable monomer, a nematic liquid crystal, a chiral molecule, a solvent, a photoinitiator, etc. may be mixed to obtain a liquid crystal solution before coating the liquid crystal on the alignment layer 122. The solvent can be cyclopentanone, butanone, ethyl acetate, butyl acetate and the like, the solid content of the prepared liquid crystal solution can be 30-40%, and the color of the liquid crystal solution can be light yellow to brown. After the liquid crystal solution is prepared, the liquid crystal solution may be coated on the alignment layer 122 by a gravure coating method using an anilox roller, and aligned according to the alignment of the alignment layer 122, thereby obtaining an aligned liquid crystal.

It should be noted that, during the subsequent operation of manufacturing the housing 100, the carrier film may be torn off to obtain the liquid crystal optical film layer 12 including the liquid crystal layer 121 and the alignment layer 122.

Referring to FIG. 8, in one embodiment, the liquid crystal optical film 12 may be formed on other structural layers by adhesion. In the present embodiment, the effect film 20 may further include an adhesive layer 13, and the adhesive layer 13 is disposed on a side of the liquid crystal layer 121 away from the alignment layer 122 to adhere the liquid crystal optical film layer 12.

Specifically, when the liquid crystal optical film layer 12 is bonded, a dimple coater may be used to coat the uv-curable adhesive on the surface of the liquid crystal layer 121 away from the alignment layer 122 by means of dimple coating, and the liquid crystal optical film layer 12 is coated and bonded on other structural layers by means of roller bonding, and then the carrier film formed when the liquid crystal optical film layer 12 is prepared is torn off as described above.

Further, referring to fig. 9, in one embodiment, the effect film 20 may further include a texture layer 14, a color layer 15 and an identification layer 16. In the present embodiment, the relative position relationship between the structural layers of the effect membrane 20 is not limited, and may be specifically set according to application requirements.

In an application scenario, the structural layers of the effect film 20 are sequentially arranged in the direction away from the substrate 10, namely, the identification layer 16, the adhesive layer 13, the liquid crystal optical film layer 12, the texture layer 14, the reflective layer 11 and the color layer 15, as shown in fig. 9.

Of course, in other application scenarios, other arrangement modes may also be adopted, as shown in fig. 10, along the direction away from the substrate 10, the arrangement order of the structural layers of the effect membrane 20 is, in order, the identification layer 16, the color layer 15, the texture layer 14, the reflection layer 11, the adhesive layer 13, and the liquid crystal optical film layer 12; as shown in fig. 11, the arrangement order of the structural layers of the effect film 20 in the direction away from the substrate 10 is the logo layer 16, the adhesive layer 13, the liquid crystal optical film layer 12, the color layer 15, the texture layer 14, and the reflective layer 11.

The texture layer 14 may have a texture pattern, so that the housing 100 can further exhibit a texture effect, and the material may be an ultraviolet light curing adhesive. Specifically, the texture layer 14 may be formed by ultraviolet light transfer or the like. In consideration of the fact that the texture layer 14 is too thin, the texture effect is poor, and the texture layer 14 is too thick, the texture layer 14 is brittle, and the adhesion is reduced, the thickness of the texture layer 14 in the present embodiment may be 15 to 30 μm, specifically 15 μm, 20 μm, 25 μm, 30 μm, or the like.

The color layer 15 may be formed by spraying, silk-screen printing, offset printing, and other processes using color ink, pigment, dye, and the like, and specifically, the formed color layer 15 may be semi-transparent or opaque according to actual requirements and through selection of raw materials and processes. The color presented by the color layer 15 can be selected according to actual requirements, and is not limited herein.

It should be noted that the color layer 15 may be black, white, or colored, and when the color is black or white, the color layer 15 may be disposed on the side of the reflective layer 11 away from the texture layer 14, as shown in fig. 9 above. When the color layer 15 is black, the color layer 15 can cooperate with the reflective layer 11 to make the reflected light show the color of the reflective layer 11; when the color of the color layer 15 is white, the color of the reflective layer 11 can be transmitted; and when the color is colorful, the color can be superposed with the color of the liquid crystal optical film layer 12 and the effect of color change with angle, so that the shell 100 can present richer colors.

The identification layer 16 may have an identification, such as a trademark of the housing 100 or the brand of the device to which the housing 100 is applied, or may be a graphic, a text, or the like customized according to the user's needs. Specifically, the identification layer 16 may be disposed between the substrate 10 and the adhesive layer 13.

Further, referring to fig. 12, in an embodiment, the housing 100 may further include a light shielding layer 30 and a protective layer 40. The light-shielding layer 30 may be disposed on one side of the effect film 20, and the protection layer 40 may be disposed on one side of the effect film 20 away from the light-shielding layer 30. Specifically, when the housing 100 is applied to an electronic device, the light shielding layer 30 is disposed at a position of the housing 100 close to the internal components of the electronic device for shielding the internal components of the electronic device, and the protective layer 40 may be an outermost side of the housing 100 far from the electronic device and protect other structural layers of the housing 100. Of course, in other embodiments, other structural layers may be further formed outside the protective layer 40, and are not limited herein.

The material forming the light shielding layer 30 may be ink or other materials, for example, in an application scenario, the material of the light shielding layer 30 is a fire retardant coating, such as a polyurethane curing system prepared from acrylic acid/isocyanate, so that the purpose of shielding light can be achieved, and a flame retardant effect can be achieved.

Specifically, the thickness of the light shielding layer 30 may be 10-15 μm, such as 10 μm, 11 μm, 12 μm, 13 μm, 14 μm, 15 μm, etc., and may be achieved by 2-3 spraying processes.

The protective layer 40 may be formed by spraying or curtain coating a hardening liquid, and the hardening liquid may be a UV-based hardening liquid. In the present embodiment, the thickness of the protective layer 40 may be 6 to 9 μm, such as 6 μm, 7 μm, 8 μm, 9 μm, etc., the protective layer 40 may satisfy the requirements of wear resistance and scratch resistance, and the hardness of the case 100 on the protective layer 40 side may satisfy not less than the pencil hardness 3H (1000 gf).

In addition, in the embodiment, the protection layer 40 may further have a certain light transmittance, so that external light can enter other structural layers of the housing 100 through the protection layer 40, thereby exhibiting a rich effect.

In the embodiment corresponding to fig. 12, the base 10 is provided between the protective layer 40 and the effect membrane 20.

Further, referring to fig. 13, in one embodiment, the substrate 10 may be disposed on a side of the light shielding layer 30 away from the effective film 20. In this embodiment, the housing 100 may further include a bonding layer 50, and the bonding layer 50 may be located between the light shielding layer 30 and the substrate 10 and is used for bonding the substrate 10 and the light shielding layer 30 together.

It should be noted that, in the present embodiment, in the manufacturing process of the casing 100, other structural layers of the casing 100, such as the light-shielding layer 30, the effect film 20, the protection layer 40, and the like, are formed first, then the adhesive layer 50 is further formed on one side of the light-shielding layer 30 by printing or the like, and then the substrate 10 is formed on one side of the adhesive layer 50 away from the other structural layers by in-mold injection, so as to obtain the casing 100 in the present embodiment.

The bonding layer 50 may be made of a material capable of achieving good bonding with the substrate 10, so as to improve adhesion between the substrate 10 and the light-shielding layer 30 and improve reliability of the housing 100.

In an application scenario, the structure of the housing 100 is the same as the housing 100 in the embodiment shown in fig. 12, wherein the thickness of the reflective layer 11 is 350 nm. In the related art, the structure of the casing may not include the liquid crystal optical film layer 12 as described above with respect to the casing 100 in fig. 12, and the thickness of the reflective layer is also 350nm, as shown in fig. 14.

In one application scenario, the surface gloss of the case a in the embodiment corresponding to fig. 12 and the gloss of the case B corresponding to fig. 14 were respectively tested by a german BYK micro-tri-angle gloss meter, wherein the case B has the same structure as the case a except that the liquid crystal optical film layer 12 is not provided, and the test results are shown in table 1 below:

TABLE 1 gloss measurement results

As can be seen from table 1 above, the liquid crystal optical film layer + reflective layer case a has higher glossiness than the related art case B without the liquid crystal optical film layer.

It should be further noted that the housing 100 in the above embodiments is not limited to be applied to the above electronic devices, and may be further applied to other objects, devices and the like in daily production and life, such as household appliances, e.g., packing boxes, automobiles and the like, and is not limited herein.
