[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only embodiments of one area of ​​the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] As mentioned in the background technology section, due to the mutual interference between the complex appearance structures, the appearance effect will be poor in quality, that is, the appearance effect is rich but the viewability is poor. Therefore, how to achieve rich appearance effects with high quality has become a problem that needs to be solved urgently by those skilled in the art.

[0046] Based on the above, the present application provides an electronic device, which can be a mobile phone, computer, tablet or other electronic product, or a component with a decorative shell in a mobile phone, computer, tablet or other electronic product. The present application does not limit this, and the specific situation depends on the specific situation. Figure 1 As shown, Figure 1 A schematic diagram of the structure of an electronic device provided in this application, the electronic device comprising:

[0047] Target component 100.

[0048] The shell 200 is a light-transmitting shell, and light can be transmitted through the shell 200. And the shell 200 is located on the target component 100, that is, the shell 200 can be the shell of the electronic device provided in the present application, and can protect the target component 100. It should be noted that the shape of the shell 200 can be adapted to the shape of the target component 100, and can be a flat plate or a curved surface. And the present application does not specifically limit the size of the shell 200. For example, the size of the shell 200 can be 300mm×200mm, or it can be a diameter of Φ=200mm, or it can be other sizes, depending on the specific situation.

[0049] The texture layer 300 is disposed on the housing 200. The target surface 301 of the texture layer 300 has a texture 310, and the texture 310 includes a first texture 311 and a second texture 312. The distance between the base surface of the first texture 311 and the housing 200 is a first distance, and the distance between the base surface of the second texture 312 and the housing 200 is a second distance, and the first distance is equal to the second distance. It should be noted that the texture layer 300 may include a light-transmitting film layer composed of a PET light-transmitting film or a PC light-transmitting film, and a cured adhesive layer on the light-transmitting film layer, and the first texture 311 and the second texture 312 may be embossed on the cured adhesive layer.

[0050] It should be noted that the target surface 301 may be the side of the texture layer 300 facing the target component 100, but this application does not limit this and it depends on the specific situation. The base surface of the first texture 311 is the surface of the target surface 301 used for imprinting the first texture 311, and the base surface of the second texture 312 is the surface of the target surface 301 used for imprinting the second texture 312. Figure 2 As shown, Figure 2 is a schematic diagram of the structure of the texture layer 300, Figure 2The dotted box 1 represents the base surface of the first texture 311, recorded as the first base surface 1, and the dotted box 2 represents the base surface of the second texture 312, recorded as the second base surface 2. The first base surface 1 and the second base surface 2 are the surfaces of the target surface 301 used to imprint the first texture 311 and the second texture 312 respectively before the first texture 311 and the second texture 312 are imprinted on the target surface 301, that is, the first base surface 1 and the second base surface 2 are the surfaces of the target surface 301 used to imprint the first texture 311 and the second texture 312 respectively, but the first texture 311 and the second texture 312 are not imprinted thereon. The distance between any point on the first base surface 1 and the shell 200 is a first distance L1, and the distance between any point on the second base surface 2 and the shell 200 is a second distance L2. The first distance L1 is equal to the second distance L2, so that the distance between each point on the first base surface 1 and the shell 200 is equal to the distance between each point on the second base surface 2 and the shell 200, that is, the height relative to the shell 200 of each area for forming the first texture 311 and each area for forming the second texture 312 in the target surface 301 is equal, that is, they are at the same height relative to the shell 200.

[0051] At the same time in the present application, the reflected light beam of the first texture 311 is emitted from the shell 200 to present a first texture effect, and the reflected light beam of the second texture 312 is emitted from the shell 200 to present a second texture effect, and the first texture effect and the second texture effect are different.

[0052] It should be noted that the reflected light beam of the first texture 311 is a light beam formed by reflection of the first texture 311, and the reflected light beam of the second texture 312 is a light beam formed by reflection of the second texture 312. For the convenience of description, the reflected light beam of the first texture 311 is recorded as the first reflected light beam, and the reflected light beam of the second texture 312 is recorded as the second reflected light beam. For the first reflected light beam, since the first reflected light beam is a light beam reflected by the first texture 311, it can carry the morphological information of the first texture 311, so that after the first reflected light beam is emitted from the light-transmitting shell 200, it will present a light beam effect with the morphological characteristics of the first texture 311, that is, the above-mentioned first texture effect. Similarly, the second reflected light beam can carry the morphological information of the second texture 312, so that after the second reflected light beam is emitted from the light-transmitting shell 200, it will present a light beam effect with the morphological characteristics of the second texture 312, that is, the above-mentioned second texture effect. Since the first texture 311 can form a texture effect having its morphological characteristics, and the second texture 312 can form a texture effect having its morphological characteristics, the first texture 311 and the second texture 312 are texture structures for forming an appearance effect in the electronic device.

[0053] Based on the above, the first texture 311 and the second texture 312 are texture structures used to form an appearance effect in the electronic device, and the first texture effect and the second texture effect are different. It is known that the first texture effect is formed by a light beam carrying the morphological information of the first texture 311, and the second texture effect is formed by a light beam carrying the morphological information of the second texture 312, so the first texture effect and the second texture effect are different, that is, the morphology of the first texture 311 and the morphology of the second texture 312 are different, so that the electronic device includes a texture that can present different texture effects, and the appearance effect of the electronic device can be richer, which helps to meet the development trend of increasingly rich appearance effects of today's electronic devices.

[0054] It can be understood that the visual effects of the first texture effect and the second texture effect of the present application are different, and the general attention and cognition of ordinary technicians in this field can be used as the standard. If the two visual effects are basically the same in visual effect, making it difficult for technicians in this field to distinguish them, they can be regarded as the same; correspondingly, if the two visual effects are different in visual effect, so that technicians in this field can distinguish the two visual effects, they can be regarded as different.

[0055] In addition, the base surface of the first texture 311 and the base surface of the second texture 312 are at the same height relative to the shell 200, that is, the first texture 311 and the second texture 312 are at the same height relative to the shell, which can eliminate the height difference between the first texture 311 and the second texture 312, and can weaken the transition line between the first texture 311 and the second texture 312, thereby improving the sense of unity of the overall texture effect presented by the first texture effect and the second texture effect, thereby improving the presentation quality of the appearance effect. At the same time, the first texture 311 and the second texture 312 are at the same height relative to the shell, eliminating the height difference between the first texture 311 and the second texture 312, and can also make the reflected light beam of the first texture 311 not affected by the second texture 311, and the reflected light beam of the second texture 312 will not be affected by the first texture 311, for example, the transmission of the reflected light beam of the first texture 311 can not be blocked by the second texture 312, and the transmission of the reflected light beam of the second texture 312 can not be blocked by the first texture 311, so that the mutual influence between the first texture 311 and the second texture 312 can be weakened, and the texture layer can present a high-quality rich appearance effect, and thus the electronic device can have a high-quality rich appearance effect.

[0056] In one embodiment of the present application, Figure 3 and Figure 4 As shown, Figure 3 is a schematic diagram of the structure of the first texture 311, Figure 4 for Figure 3In the cross-sectional view along AA1, the first texture 311 may include a first sub-texture 3111 and a second sub-texture 3112. The first sub-texture 3111 may be a groove extending along a first direction on the target surface 301, the first direction may be parallel to the target surface 301, and the first direction may be the Y-axis direction. It should be noted that Figure 3 and Figure 4 It is only a schematic diagram of the structure of the first texture 311 and does not represent the actual structure of the first texture 311. Figure 3 The arrangement of the plurality of first textures 311 is only a schematic diagram. The arrangement of the first textures 311 may be as follows: Figure 3 The discrete arrangement shown may also be a closely adjacent arrangement, or may be an arrangement other than the above two arrangements.

[0057] The second sub-texture 3112 may be located on the first sub-texture 3111, and in the second direction, the second sub-texture 3112 may be a depression relative to the first sub-texture 3111, the second direction may be perpendicular to the target surface 301, and the projection of the second sub-texture 3112 along the second direction may be located in the projection of the first sub-texture 3111 along the second direction, and the second direction may be the Z-axis direction. In other words, the second sub-texture 3112 may be a depression relative to the surface of the first sub-texture 3111 surrounding it, and the second sub-texture 3112 may be smaller than the first sub-texture 3111 and disposed in the first sub-texture 3111, that is, the second sub-texture 3112 may be a depression embedded in the first sub-texture 3111, and the first texture 311 is a composite texture.

[0058] Figure 3 is a top view of the texture layer 300, Figure 4 for Figure 3 Sectional view along AA1, reference Figure 3 The target surface 301 may be in a rectangular shape, and the target surface 301 has a first side 3011 and a second side 3012 adjacent to each other, and the rectangle of the target surface 301 includes two opposite first sides 3011 and two opposite second sides 3012. Figure 3 and Figure 4, the coordinate system with O as the origin is explained, and the same explanation applies to the coordinate system with O as the origin in the following figures. In the coordinate system with O as the origin, the X-axis and the Y-axis are perpendicular to each other, the Z-axis is perpendicular to the XOY plane, the X-axis is parallel to the first side 3011, and the Y-axis is parallel to the second side 3012, so that the XOY plane can be parallel to the target surface 301, and the Z-axis can be perpendicular to the target surface, and the Z-axis can point from the target surface 301 to the back side 302 of the texture layer 300. The back side 302 of the texture layer 300 is the side opposite to the target surface 301. The target surface 301 may be the side of the texture layer 300 facing the target component 100, and the back side 302 of the texture layer 300 may be the side of the texture layer 300 facing away from the target component 100 and connected to the housing 200. That is, the Z axis may extend from the target surface 301 to the inside of the texture layer 300 and point to the back side 302 of the texture layer 300, so that the Y axis may be perpendicular to the target surface 301 and extend from the target surface 301 to the inside of the texture layer 300 and point to the back side 302 of the texture layer 300. Figure 3 and Figure 4 , the first sub-texture 3111 extends from one of the second sides 3012 of the target surface 301 to the other second side 3012 along the first direction, so the first direction can be parallel to the Y axis, that is, the Y axis of the coordinate system with O as the origin can represent the first direction. In addition, in the second direction, the second sub-texture 3112 can be a depression relative to the first sub-texture 3111, that is, the second sub-texture 3112 can be a depression concave toward the texture layer 300 relative to the first sub-texture 3111, so the second direction can be parallel to the Z axis, that is, the Z axis of the coordinate system with O as the origin can represent the second direction. It should be understood that the above-mentioned first direction represents that the first sub-texture 3111 extends from one of the second sides 3012 of the target surface 301 to the other second side 3012, that is, the first direction represents the change trend of the extension direction of the first sub-texture 3111, and does not limit the first sub-texture 3111 to extend along the first direction everywhere.

[0059] Based on the above, the first texture 311 is a composite texture that may include a first sub-texture 3111 and a second sub-texture 3112, and the reflected light beam of the first texture 311 will present a texture effect having the morphological characteristics of the first texture 311, so the first texture effect may include a texture effect corresponding to the first sub-texture 3111, and a texture effect corresponding to the second sub-texture 3112.

[0060] The first sub-texture 3111 may be a groove extending along the first direction in the target surface 301, that is, the first sub-texture 3111 may be formed by a depression in the target surface 301 extending along the first direction. Since the depression is used to form the first sub-texture 3111, that is, to form a texture structure, the size of the depression may be small, and the light may be vertically incident when transmitted to the depression. Figure 5 As shown, for example, when the projection of the depression used to form the first sub-texture 3111 along the first direction is an arc, that is, when the cross section of the depression used to form the first sub-texture 3111 is an arc, as the depth of the depression increases, more reflected light beams can be emitted from the depression, and the brightness of the reflected light beam can gradually increase, so that the depression of the first sub-texture 3111 presents a dark-light-dark gradient texture effect in its cross-sectional direction, that is, the first sub-texture 3111 can present a light-dark gradient texture effect based on the cross-sectional shape of its depression. In addition, since the first sub-texture 3111 can be a groove extending along the first direction in the target surface 301, and then its morphological features can include a columnar morphology extending along the first direction, the texture effect of the first sub-texture 3111 can also include a columnar light and shadow extending along the first direction, that is, the first texture effect can be expressed as a composite texture effect of light-dark gradient combined with a columnar texture effect, which can enrich the appearance effect and contribute to the development trend of increasingly rich appearance effects of today's electronic devices.

[0061] The second sub-texture 3112 may be a depression embedded in the first sub-texture 3111, and the second sub-texture 3112 may be smaller than the first sub-texture 3111, so that for the area of ​​the first sub-texture 3111 having the second sub-texture 3112, the second sub-texture 3112 forms a rough surface of the first sub-texture 3111, and the second sub-texture 3112 may diffusely reflect the reflected light beam of the first sub-texture 3112. Since the second sub-texture 3112 may diffusely reflect the reflected light beam of the first sub-texture 3112, for the edge of the groove of the first sub-texture 3111, the reflected light beam at the edge may be diffusely reflected in multiple directions by the second sub-texture 3112, so that the transition of the reflected light beam at the edge of the groove is smooth, and the edge transition of the columnar light and shadow presented by the first sub-texture 3111 is smooth. At the same time, for the position where the depth of the depression in the groove of the first sub-texture 3111 changes abruptly, since the second sub-texture 3112 forms the rough surface of the first sub-texture 3111, the reflected light beam of the first sub-texture 3112 can be diffusely reflected, and the reflected light beam at the position where the depth of the depression changes abruptly can also have a smooth transition, and thus the texture effect presented at the position where the depth of the depression changes abruptly can have a smooth transition. It can be seen that the second sub-texture 3112 is a depression embedded in the first sub-texture 3111, and the second sub-texture 3112 can be smaller than the first sub-texture 3111, and can diffusely reflect the reflected light beam of the first sub-texture 3111, so that the texture effect formed by the first sub-texture 311 can have a smooth transition everywhere, presenting a high-quality and rich appearance effect.

[0062] It should be noted that, in the present application, the second sub-texture 3112 may partially cover the first sub-texture 3111, and the second sub-texture 3112 may diffusely reflect a portion of the reflected light beam of the first sub-texture 3111; the second sub-texture 3112 may also completely cover the first sub-texture 3111, and the second sub-texture 3112 may diffusely reflect all of the reflected light beam of the first sub-texture 3111.

[0063] In one embodiment of the present application, Figure 6 As shown, in the first direction, at least part of the first sub-texture 3111 may not be located in the same straight line, that is, at least part of the first sub-texture 3111 in its extension direction may not be located in the same straight line, that is, the shape of the projection of the first sub-texture 3111 along the second direction may not be a straight line, and the first sub-texture 3111 may be a non-linear groove extending along the first direction on the target surface 301. For example Figure 3As shown, the projection of the first sub-texture 3111 along the second direction can be wavy, that is, the first sub-texture 3111 can be a wavy groove extending along the first direction on the target surface 301, so that the texture effect of the first sub-texture 3111 can be presented in multiple directions. In other words, when observing the electronic device from multiple directions, the texture effect of the first sub-texture 3111 can be observed, presenting a richer texture effect.

[0064] It should be noted that, in addition to being a wavy groove extending along the first direction on the target surface 301, the first sub-texture 3111 can also be a parabolic groove or other curved grooves. The present application does not limit this and it depends on the specific situation.

[0065] In one embodiment of the present application, in the first direction, the texture depth of the first sub-texture 3111 at each location may be the same, that is, the texture depth of the first sub-texture 3111 at each location in its extension direction may be the same. The texture depth of the first sub-texture 3111 may be the depth of the depression of the first sub-texture 3111 along the second direction, that is, the texture depth of the first sub-texture 3111 may be the depth of the depression of the first sub-texture 3111 relative to the base surface. The texture depth of the first sub-texture 3111 may be 1 μm -10 μm, including the endpoint value, but the present application does not limit this, and it depends on the specific situation.

[0066] Based on the above, the texture depth of the first sub-texture 3111 at various locations in its extension direction can be the same, that is, the texture depth of the first sub-texture 3111 at various locations in its extension direction can be kept consistent, so that the texture effect presented at various locations in the extension direction of the first sub-texture 3111 can also be consistent, and thus the appearance effect of the electronic device provided by the present application is rich and regular, and is ornamental, which can meet the development trend of the increasingly rich appearance of electronic devices today.

[0067] In one embodiment of the present application, Figure 7 As shown, the texture depths d1 of adjacent first sub-textures 3111 may be different, and the texture depth of the first sub-texture 3111 may be characterized by the maximum texture depth of the first sub-texture 3111. It is known that the reflected light beam of the first sub-texture 3111 will carry the morphological features of the first sub-texture 3111, so the texture depths of the first sub-texture 3111 may be different, which means that the texture effects presented by the reflected light beam of the first sub-texture 3111 after being emitted through the housing 200 may also be different. Based on this, the texture depths of adjacent first sub-textures 3111 may be different, and the texture effects presented by the reflected light beams of adjacent first sub-textures 3111 after being emitted through the housing 200 may also be different, so that the first texture effect may be composed of a combination of multiple different columnar light and shadows, which may achieve a richer appearance effect, and help meet the development trend of increasingly rich appearance of today's electronic devices.

[0068] In one embodiment of the present application, continue as Figure 7 As shown, the spacing d2 between adjacent second sub-textures 3112 can be the same, and the texture depth d3 of adjacent second sub-textures 3112 can be the same, the spacing between adjacent second sub-textures 3112 can be characterized by the minimum spacing between adjacent second sub-textures 3112, and the texture depth of the second sub-texture 3112 can be characterized by the maximum texture depth of the second sub-texture. The texture depth of the second sub-texture 3112 can be the depth of the depression of the second sub-texture 3112 along the second direction, and the texture depth of the second sub-texture 3112 is 1μm-10μm, including the endpoint value. It should be noted that the present application does not limit the specific value of the texture depth of the second sub-texture 3112, which depends on the specific situation.

[0069] Based on the above, since the spacing between adjacent second sub-textures 3112 can be the same, and the texture depths of adjacent second sub-textures 3112 can be the same, the second sub-texture 3112 can be depressions evenly distributed in the first sub-texture 3111, and the inner depth of the depressions is the same, so that the second sub-texture 3112 at each location of the first sub-texture 3111 can have the same influence on the texture effect presented by the first sub-texture 3111, so that the second sub-texture 3112 can make the texture effect formed by the first sub-texture 3111 have a smooth transition without affecting the consistency of the texture effect presented at each location in the extension direction of the first sub-texture 3111, and thus the electronic device provided by the present application has a rich and regular appearance effect, is ornamental, and can meet the development trend of the increasingly rich appearance of electronic devices today.

[0070] Since the second sub-texture 3112 can be a depression embedded in the first sub-texture 3111, it can be used as a frosted texture to present a frosted effect, reduce the brightness of the light beam reflected by the first sub-texture 3111, and thus suppress the glossiness of the first texture effect to avoid the appearance of the electronic device being too dazzling and affecting the viewability. In addition, the texture depth of the second sub-texture 3112, that is, the depression depth, can be the same, so that the shape of the second sub-texture 3112 at various locations on the target surface 301 can be consistent, which can reduce the difficulty of preparing the second sub-texture 3112, thereby simplifying the preparation process of the electronic device.

[0071] In one embodiment of the present application, Figure 8As shown, the projection of the second sub-texture 3112 along the second direction can be circular, and the projection of the second sub-texture 3112 along the third direction can be arc-shaped, the third direction can be parallel to the target surface 301 and perpendicular to the first direction, that is, the top view of the second sub-texture 3112 observed along the second direction can be circular, and the side view observed along the third direction can be arc-shaped, that is, the cross-sectional view of the second sub-texture 3112 along the extension direction (first direction) of the first sub-texture 3111 can be arc-shaped, the third direction can be parallel to the first direction, the second sub-texture 3112 can be a spherical depression in the first sub-texture 3111, and the concave surface of the second sub-texture 3112 can be different from each other, so that the reflected light beam of the first sub-texture 3111 can be transmitted in different directions after being reflected by the second sub-texture 3112, and then the reflected light beam of the first sub-texture 3111 can be diffusely reflected in multiple directions, so that the cylindrical light and shadow formed by the first sub-texture 3111 can be smoothly transitioned at various places.

[0072] In one embodiment of the present application, the diameter of the second sub-texture may be 5 μm-15 μm, including end values, but the present application does not limit this, and it depends on the specific situation.

[0073] In one embodiment of the present application, the second texture 312 may be a mirror texture, that is, the area of ​​the target surface 301 where the second texture 312 is located may be a mirror, so that the brightness of the second texture effect is higher, which is different from the first texture effect, so as to enrich the appearance of the electronic device. It should be noted that in other embodiments of the present application, the second texture 312 may also be other textures with higher brightness in addition to the mirror texture, and the present application does not limit this, and it depends on the specific situation.

[0074] In one embodiment of the present application, Fig. 9 As shown, the second texture 312 is imprinted on the base surface of the second texture 312, and a preset pattern A can be formed in the target surface 301. That is, when the second texture 312 is imprinted on its base surface, a preset pattern A can be formed in the target surface 301, and then the second texture 312 can form a preset pattern showing a second texture effect in the target surface 301. The above-mentioned preset pattern A can represent the product information of the electronic device. For example, the preset pattern A can be the brand name (also called the brand logo) of the electronic device, so that the brand logo in the shell of the electronic device can present a texture effect different from other areas, thereby enriching the appearance of the electronic device. However, the present application is not limited to this, and it can also be other product information of the electronic device, such as device parameters, etc., depending on the specific circumstances. It should be noted that, if Fig. 9As shown, the area where the second texture 312 is located is the middle area of ​​the target surface 301, which is surrounded by the area where the first texture 311 is located, but the present application does not limit this and it depends on the specific situation.

[0075] From the above, it can be seen that the second texture 312 is located in a preset area of ​​the preset pattern, the first texture 311 is located in an area outside the preset area, and the surface where the second texture 312 is located is at the same height as the surface where the first texture 311 is located, so that there is no transition line difference between the texture effect of the preset pattern and the texture effect of its surrounding area, and a strong sense of unity is achieved, thereby presenting a good appearance effect.

[0076] Based on the above embodiments, in one embodiment of the present application, since glass has advantages such as high hardness, high light transmittance, and low cost, the housing 200 may be a glass housing, and the texture layer 300 may be disposed on the glass housing. However, the present application does not limit this, and it depends on the specific situation.

[0077] The present application also provides a preparation method, which is used to prepare the electronic device shown in any of the above embodiments. Fig.10 As shown in the figure, it is a flow chart of a preparation method provided by the present application, and the preparation method comprises:

[0078] S1: Provide an imprint substrate, which may be composed of a film substrate and a curing adhesive layer on the film substrate. The film substrate may be a light-transmitting substrate such as a PET film substrate or a PC film substrate, and the curing adhesive may be a UV curing adhesive.

[0079] S2: Imprinting the first texture and the second texture on the imprint substrate to form a texture layer, wherein the first texture and the second texture are located on a target surface of the texture layer. Step S2 may specifically be imprinting the first texture and the second texture on the curing adhesive of the imprint substrate to form a texture layer, wherein the first texture and the second texture may be located on a target surface of the curing adhesive.

[0080] S3: Disposing the texture layer on a shell of the electronic device, wherein the shell covers a target component of the electronic device, and the shell is a light-transmitting shell.

[0081] The distance between the base surface of the first texture and the shell is the first distance, the distance between the base surface of the second texture and the shell is the second distance, and the first distance and the second distance are equal. The base surface of the first texture is the surface of the target surface used to form the first texture, and the base surface of the second texture is the surface of the target surface used to form the second texture.

[0082] The reflected light beam of the first texture is emitted from the shell to present a first texture effect, and the reflected light beam of the second texture is emitted from the shell to present a second texture effect, and the first texture effect and the second texture effect are different.

[0083] Based on the above, the first texture and the second texture are texture structures for forming an appearance effect, and the first texture effect of the first texture and the second texture effect of the second texture are different, that is, the electronic device can have a variety of texture effects, so that the appearance effect of the electronic device is richer, which helps to meet the development trend of the increasingly rich appearance of today's electronic devices. In addition, the base surface of the first texture and the base surface of the second texture are at the same height relative to the shell, which can eliminate the height difference between the first texture and the second texture, weaken the transition line between the first texture and the second texture, and then weaken the mutual influence between the first texture and the second texture, presenting a high-quality and rich appearance effect.

[0084] Based on the above embodiments, in one embodiment of the present application, for the above step S2, imprinting the first texture and the second texture on the imprint substrate to form the texture layer includes:

[0085] Imprinting the first texture and the second texture on the imprint substrate using an imprint element to form a texture layer;

[0086] The embossing element has a third texture and a fourth texture, the third texture is used to form the first texture, and the fourth texture is used to form the second texture.

[0087] From the above, it can be seen that the preparation method uses an imprinting element to form a texture layer, and the imprinting element has a third texture and a fourth texture corresponding to the first texture and the second texture respectively. That is to say, the first texture and the second texture in the texture layer are imprinted in the same imprinting process using an imprinting template, which can simplify the preparation process of the texture layer and further simplify the preparation process of the electronic device.

[0088] Furthermore, the texture layer is formed by embossing a template, so that for the same electronic product, or the same texture layer of different electronic products, the texture layer can be replicated, and thus the appearance effect can be reproduced. The preparation method has strong applicability and practicality.

[0089] In the present application, the preparation process of the above-mentioned embossing element includes: Fig.11As shown, 1. Provide a first substrate, and use grayscale lithography to form a third texture on the first substrate. 2. Provide a second substrate, and use UV transfer to transfer the third texture on the first substrate to the second substrate. It can also be other transfer processes, and the present application does not limit this. 3. Provide a third substrate, and the third substrate is a film with a preset pattern. 4. Imprint the third texture on the second substrate to the third substrate. 5. Expose and develop the third substrate. 6. Wash the glue to remove the third texture in the area where the preset pattern is located, and form a hollow with a preset pattern. 7. Fill the hollow area with curing glue, such as UV glue, to form a fourth texture on the curing glue. 8. Then perform UV curing to form the third texture and the fourth texture on the third substrate. 9. Provide a fourth substrate, and transfer the third texture and the fourth texture on the third substrate to the fourth substrate. The surface of the fourth substrate where the third texture is imprinted is the same height as the surface where the fourth texture is imprinted. The fourth substrate can be used as the above-mentioned imprinting element.

[0090] Since the first texture is a composite texture, and the texture depths of the first sub-texture and the second sub-texture are different, and the texture depths of adjacent first sub-textures are also different, grayscale lithography is required to prepare the third texture corresponding to the first texture on the first substrate. However, grayscale lithography requires high-precision equipment, and has very high requirements on the precision of light source intensity and time, high cost, and great processing difficulty. As can be seen from the above, in the process of preparing the imprinting element, the third texture on the first substrate can be transferred to the second substrate by UV transfer, and in the subsequent preparation process, that is, the first substrate formed with the third texture can be used as an imprinting template for imprinting the third texture, so that when preparing the imprinting element, it is not necessary to use grayscale lithography to form the third texture in the preparation process of each imprinting element, and the first substrate with the third texture can be used for imprinting, which is fast and low-cost.

[0091] Based on the above, after the third texture and the fourth texture are formed on the fourth substrate, the fourth substrate can be used as an imprinting element, and can be used to form the first texture and the second texture on the imprinting substrate. That is to say, the preparation method provided in the present application uses the imprinting element as the imprinting template to form the first texture and the second texture on the imprinting substrate without the need for complex etching steps. The preparation of the first texture and the second texture can be completed by the same one-time imprinting process. Therefore, the preparation method provided in the present application is fast, low-cost, and highly economical.

[0092] In addition, when preparing the embossed element, a hollowing out of a preset pattern is formed in the area where the third texture is located, and then the hollowing out area is filled and embossed with the fourth texture, so that the third texture and the fourth texture can be spliced ​​on the same surface, so that the third texture and the fourth texture can be subsequently formed on surfaces of the same height.

[0093] In summary, the present application provides an electronic device and a preparation method, the electronic device comprising: a target component, a shell and a texture layer. The shell is a light-transmitting shell, which is located on the target component. The texture layer is arranged on the shell, and its target surface has a texture. The texture comprises a first texture and a second texture, the first texture and the second texture are texture structures used to form an appearance effect in an electronic device, and the first texture effect presented by the first texture is different from the second texture effect presented by the second texture, so that the electronic device comprises a texture that can present different texture effects, and thus the appearance effect of the electronic device can be richer. In addition, the distance between the base surface of the first texture and the shell is the first distance, and the distance between the base surface of the second texture and the shell is the second distance, and the first distance is equal to the second distance, that is, the first texture and the second texture are at the same height relative to the shell, and the height difference between the first texture and the second texture can be eliminated, and the reflected light beam of the first texture can not be affected by the second texture, and the reflected light beam of the second texture can not be affected by the first texture, so that the mutual influence between the first texture and the second texture can be weakened, and the texture layer can present a high-quality rich appearance effect, and thus the electronic device can have a high-quality rich appearance effect.
