Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

In the description of the present application, it is to be understood that the terms "length," "width," "left," "right," "inner," "outer," and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present application.

A method of processing a membrane 100, a housing assembly 500, and an electronic device 600 according to an embodiment of the present application are described below with reference to fig. 1 to 8.

As shown in fig. 1 to 5, a method for processing a membrane 100 according to an embodiment of the present application includes: a first film layer 10 and a second film layer 20 are prepared.

As shown in fig. 2, the preparing of the first film layer 10 includes: the first texture layer 120 is formed by UV transfer printing on a portion of the surface of the first substrate 110. It should be noted that the first substrate 110 may be, but is not limited to, a PET film (polyethylene terephthalate), and the first texture layer 120 is formed on a portion of the surface of the first substrate 110 by using a UV transfer process. The UV transfer process may be understood as transferring the texture on the tailored mold to the surface of the substrate by using UV glue (ultraviolettrays) having photo-curing properties. The texture of the first texture layer 120 may be formed as a texture layer having a gradient effect. For example, the texture of the first texture layer 120 may be lines of gradually varying width, or circular holes of gradually varying size and density, or the like. In one embodiment, the texture of the first texture layer 120 is square squares, the width of the squares may range from 60 microns to 70 microns, and the line diameter forming the squares may range from 3 microns to 12 microns. It will be appreciated that to achieve the gradient effect, the line diameters forming the squares may vary gradually according to the direction of the gradient, for example, in the lightest areas the line diameters may be between 3 and 5 microns and in the darkest areas the line diameters may be between 8 and 12 microns.

The first texture layer 120 is inked to form a gradient color layer 130. That is, the texture (e.g., lines forming squares) in the first texture layer 120 is filled with ink, and thus, when the first texture layer 120 is filled with ink, the gradation color layer 130 having a gradation effect may be formed on a portion of the surface of the first substrate 110.

The color layer 140 is silk-screened in the area of the surface of the first substrate 110 where the gradient color layer 130 is not disposed. That is, the color layer 140 is silk-screened on the area of the surface of the first substrate 110 where the gradient color layer 130 is not disposed by using a silk-screening process. The color of the color layer 140 may be the same as the color of the gradient color layer 130, or may be different from the color of the gradient color layer 130. When the color layer 140 has a different color from the color gradient layer 130, the surface of the first substrate 110 may be colored to have a color gradient effect from the color layer 140 to the color gradient layer 130. This improves the appearance of the film 100.

As shown in fig. 3, preparing the second film layer 20 includes: the second texture layer 220 is formed on the surface of the second substrate 210 by UV transfer. The second substrate 210 may be, but is not limited to, a PET film. For example, a texture having a refraction effect or a different pattern may be formed on the surface of the second substrate 210 through a UV transfer process. Therefore, when the light passes through the second texture layer 220, the second texture layer 220 may refract the light having the texture pattern toward the first film layer 10. Also, the light intensity of the first film layer 10 may be enhanced, thereby improving the visual effect of the film 100.

The second texture layer 220 is coated to form a coating layer 230. It should be noted that, by coating the second texture layer 220, light can be reflected by the coating layer 230, and the reflected light can be transmitted into the first film layer 10, so as to enhance the light intensity of the first film layer 10.

An ink layer 240 is disposed on the coating layer 230. It can be understood that, by disposing the ink layer 240 on the film coating layer 230, light can be effectively prevented from passing through the ink layer 240.

Finally, color layer 140 is attached to second substrate 210 to form membrane 100. As shown in fig. 5, the color layer 140 of the first film layer 10 and the second substrate 210 of the second film layer 20 may be adhered by an oca (optically Clear adhesive) glue layer, so as to form the film 100.

According to the processing method of the film 100, the film 100 is formed by the first film layer 10 and the second film layer 20 which are arranged in a stacked mode, the first film layer 10 can enable the film 100 to have a gradual color effect, and the second film layer 20 can enhance the light intensity effect of the first film layer 10 and refract light with texture patterns to the first film layer 10. Thereby, the aesthetic appearance and visual effect of the film 100 are improved. Moreover, the processing method of the diaphragm 100 is simple to operate and low in cost.

According to some embodiments of the present application, as shown in fig. 5, the color layer 140 may include a plurality of colors arranged at intervals. Thus, the first film layer 10 can have various colors, and the appearance of the film 100 is improved. As shown in fig. 5, two different colors may be provided at the left and right ends of the first substrate 110 at intervals, for example, the left side may be provided with red, and the right side may be provided with blue. Between red and blue is black with a gradient effect formed by ink filling of the first texture layer 120. Therefore, the appearance surface of the membrane 100 can present three-color gradual change effects of red, black and basket. Thereby enhancing the visual appearance of the film 100.

It is understood that the above-mentioned selection and position layout of the colors of the gradient color layer 130 and the color layer 140 are only exemplary, and the selection of the colors of the gradient color layer 130 and the color layer 140 and the layout of the color positions can be designed accordingly according to the actual appearance requirement in the actual production process.

In some embodiments of the present application, when the second texture layer 220 is plated, the second texture layer 220 is sequentially plated with: a silicon oxide layer, an indium layer, an aluminum oxide layer and a titanium oxide layer. That is, the plating layer 230 may include a silicon oxide layer, an indium layer, an aluminum oxide layer, and a titanium oxide layer, which are sequentially disposed. It should be noted that the silicon oxide layer has good adhesion, which can improve the stability and reliability of the adhesion between the film coating layer 230 and the second texture layer 220, the aluminum oxide layer and the titanium oxide layer can be used as dielectric layers, and the indium layer has good light reflection effect. Therefore, the film coating layer 230 has a good light reflection effect, and the brightness of the film 100 is enhanced.

According to some embodiments of the present disclosure, multiple ink layers 240 are silk-screened onto coating 230. That is, the multi-layer ink layer 240 may be silk-screened on the plating layer 230 by a silk-screening process. It can be understood that, by silk-screening the multiple layers of ink layers 240, the light effect can be effectively prevented from passing through the ink layers 240, so that the light in the second film layer 20 can be reflected by the film coating layer 230 or absorbed by the ink layers 240. For example, coating 230 may be screen printed with three or more ink layers 240.

In some embodiments of the present application, the depth of the texture on the first texture layer 120 is h1, and the width of the texture is w1, satisfying: h1 is more than or equal to 4.5um and less than or equal to 5.5um, and w1 is more than or equal to 3um and less than or equal to 12 um. It should be noted that, the first texture layer 120 may be formed on a portion of the surface of the first substrate 110 by a UV transfer process by engraving a texture on the PC mold using a laser. Through experimental verification, when the depth of the texture meets the following conditions: when h1 is not less than 4.5um and not more than 5.5um, the laser engraving can be controlled conveniently, and the texture has good chromaticity after being filled with ink. The width of the texture satisfies: w1 is more than or equal to 3um and less than or equal to 12 um. For example, the width of the texture may be designed in a gradient manner, the width of the texture in the lighter color region may range from 3um to 5um, and the width of the texture in the darker color region may range from 8um to 12 um. Therefore, after the texture is filled with ink, a good gradual color effect can be formed on part of the surface of the first substrate 110.

According to some embodiments of the present application, the first texture layer 120 is inked to form the gradient color layer 130 using an ink having a particle size d1 satisfying: d1<1 um. It can be understood that the use of the nano ink with small particle size for ink filling can prevent the film 100 from generating granular visual perception, so that the film 100 can present a more uniform and bright color.

In some embodiments of the present application, the gradient color layer 130 is a different color than the color layer 140. For example, black, red, blue or other colors may be filled in the texture of the first texture layer 120 to form the gradient color layer 130, and the color layer 140 is a color different from the gradient color layer 130, so that the film may exhibit an effect of gradually changing from the color of the color layer 140 to the color of the gradient color layer 130, the film 100 may have a bicolor gradient effect, and the appearance of the film 100 may be enhanced.

According to some embodiments of the present application, the color layer 140 may include two different colors, and the two different colors may be spaced apart on both sides of the gradient color layer 130 along the width direction or the length direction of the film sheet 100. As shown in fig. 5, the gradient color layer 130 may be black, the color layer 140 may be red and blue, and the red and blue may be disposed at both sides of the black gradient color layer 130 at intervals in the width direction of the film 100. This makes it possible to make the entire film 100 exhibit the effect of three-color gradation of blue, black, and red along the width direction of the film 100.

Of course, two different colors of the color layer 140 may be provided at intervals along the length of the film 100 on both sides of the gradient color layer 130. Thus, the film 100 can be made to exhibit a three-color gradient along its length. It is understood that the color layer 140 may also include a plurality of colors, and different colors may be spaced in different directions with the gradient color layer 130 between adjacent different colors. Thereby, the diaphragm 100 has a multi-color gradual change effect, and the diaphragm 100 has a colorful appearance effect.

In some embodiments of the present application, after the first texture layer 120, the gradient color layer 130, and the screen-printed color layer 140 are formed, a protective film is attached for temporary protection, and then the protective film is removed. For example, after the first texture layer 120 is formed by transferring a portion of the surface of the first film layer 10, a protective film may be attached to the first texture layer 120 to temporarily protect the first texture layer 120 from dust and impurities entering the texture of the first texture layer 120. When it is desired to ink-fill the first texture layer 120, the protective film may be removed.

After the first texture layer 120 is filled with ink, the protective film may be attached again for temporary protection, so as to avoid the influence of dust and impurities on the gradient color layer 130. After the ink is dried, the protective film may be removed, and the color layer 140 may be silk-screened on the first substrate 110. A protective film may be attached again on the color layer 140 for dust protection. Thereby, the processing quality of the diaphragm 100 is improved.

According to some embodiments of the present disclosure, after the second texture layer 220, the coating layer 230 and the ink layer 240 are formed, a protective film is attached for temporary protection, and then the protective film is removed.

After the second substrate 210 is UV-transferred to form the second texture layer 220, a protective film may be attached to the second texture layer 220 for temporary protection, so as to prevent dust and impurities from entering the texture of the second texture layer 220. When it is necessary to coat the second texture layer 220, the protective film can be removed. After finishing the coating, can carry out interim protection at the attached protection film of coating 230, can take off the protection film afterwards to coating 230 silk screen printing ink layer 240, can attach the protection film once more after toasting printing ink layer 240 and carry out the dust-proof protection.

According to the housing assembly 500 of the embodiment of the present application, as shown in fig. 6, the housing assembly 500 includes: the base layer 510 and the membrane 100, the base layer 510 is made of transparent material, and the membrane 100 is attached to the inner surface of the base layer 510. Thus, the appearance effect of the film 100 can be exhibited through the base layer 510.

As shown in fig. 5, the film 100 includes a first film layer 10 and a second film layer 20, which are sequentially stacked, wherein the first film layer 10 includes: a first substrate 110, a gradient color layer 130, and a color layer 140. It should be noted that the first texture layer 120 having a gradation effect may be formed on a portion of the surface of the first substrate 110 by a UV transfer process, and the gradation color layer 130 may be formed by filling ink into the first texture layer 120. The color layer 140 is silk-screened on the area of the surface of the first substrate 110 where the gradient color layer 130 is not disposed, so that the first film layer 10 can form a two-color or multi-color gradient effect.

The second film layer 20 includes, in a stacked arrangement: a second substrate 210, a second texture layer 220, a coating layer 230 and an ink layer 240. It should be noted that the second texture layer 220 with a specific pattern refraction effect can be formed on the surface of the second substrate 210 by using a UV transfer printing process, and the plated film layer 230 has a good reflection effect by plating the second texture layer 220. The ink layer 240 can effectively prevent light from passing through the second film layer 20, so that the light entering the second film layer 20 can be totally reflected or absorbed.

The color layer 140 is attached to the second substrate 210. As shown in fig. 5, the color layer 140 of the first film layer 10 and the second substrate 210 of the second film layer 20 may be bonded using an OCA glue layer 40. Thus, the firmness and stability of the attachment of the first film layer 10 and the second film layer 20 can be improved. Moreover, the OCA glue layer 40 has a good light transmission effect, and interference influence on light is effectively avoided.

According to the housing assembly 500 of the embodiment of the present application, by attaching the film sheet 100 in the base layer 510, the first film layer 10 can generate a multi-color gradient effect, and the second film layer 20 can reflect or refract light to the first film layer 10, thereby enhancing light intensity of the first film layer 10 and forming light with different texture patterns. Therefore, the shell assembly 500 has good appearance effect and visual experience, and the appearance attractiveness of the shell assembly 500 is improved.

According to some embodiments of the present application, the gradient color layer 130 is a different color than the color layer 140. That is, the gradation color layer 130 and the color layer 140 may adopt different colors. For example, black, blue, red or other colors may be filled in the texture of the first texture layer 120 to form the gradient color layer 130, and the color layer 140 is a color different from the gradient color layer 130, so that the housing assembly 500 may have a two-color gradient appearance effect, which enhances the aesthetic appearance of the housing assembly 500.

In some embodiments of the present application, the color layer 140 includes a plurality of colors arranged at intervals with a gradient color layer 130 between adjacent different colors. As shown in fig. 5, the color layer 140 may include two different colors, such as blue and red, between which may be a black gradient color layer 130. Thus, the housing assembly 500 may be made to exhibit three-color gradation effects of blue, black, and red. It is understood that the selection and layout of the colors of the gradient color layer 130 and the color layer 140 can be selected according to actual needs, so that the housing assembly 500 has color gradient effects with different colors and different directions, so as to improve the aesthetic appearance of the housing assembly 500.

Therefore, the film 100 can form a multi-color gradual change effect through the gradual change color layer 130 and the color layer 140 of the first film layer 10, and the second film layer 20 can refract light with texture patterns to the first film layer 10, so that the appearance attractiveness of the film 100 is improved, and the shell assembly 500 of the mobile phone has a good visual effect.

Moreover, compared with a processing method for realizing the appearance gradient effect of the shell assembly 500 by adopting glass coating, the processing cost of the gradient scheme of the diaphragm 100 is low, and more than 3 dollars can be saved by integrating single sheets. In addition, the impact strength of the glass substrate 510 of the gradual change scheme of the film 100 is not reduced, the strength of the glass substrate 510 can be effectively maintained, and the user experience of the mobile phone is improved.
