Description

Technical Field

[0001] This application relates to the field of optical decorative parts technology, and more particularly to a microtextured component, housing, and device. Background Technology

[0002] 3D dynamic lighting effects have become a popular trend in product design. The floating light and shadow effects achieved through grating structures can significantly enhance the technological and artistic feel of product designs.

[0003] Currently, lenticular printing technology achieves stereoscopic vision by printing multi-view images onto a planar substrate and combining it with a lenticular plate. Specifically, several lenticular sheets are set on the lenticular plate. The lenticular sheets selectively reflect light, and the lenticular sheets with continuously changing angles will selectively reflect light in different directions, thus producing the movement of light and shadow.

[0004] However, existing lenticular lenses offer only a limited sense of depth and cannot meet the demands of dynamic visual applications. Utility Model Content

[0005] This application provides a microtextured component, housing, and device to address the shortcomings of related technologies.

[0006] In a first aspect, this application provides a microtextured component, comprising:

[0007] basal layer;

[0008] Multiple texture patterns are disposed on the base layer, at least one of which includes a first grating group and a second grating group. Both the first grating group and the second grating group have multiple grating bodies arranged along a preset direction, and the multiple grating bodies have a gradually changing deflection angle with respect to the preset direction.

[0009] The range of change of the deflection angle of the first grating group is different from the range of change of the deflection angle of the second grating group.

[0010] In one possible implementation, the texture graphic has multiple distribution areas, which are arranged along a preset direction. Each distribution area is provided with at least two grating bodies, which include a first grating body and a second grating body. In any one of the distribution areas, the extension directions of the first grating body and the extension directions of the second grating body are different.

[0011] The first grating body has a first deflection angle with the preset direction, and the first deflection angle of the plurality of first grating bodies gradually changes along the preset direction;

[0012] The second grating body has a second deflection angle with respect to the preset direction, and the second deflection angle of the plurality of second grating bodies gradually changes along the preset direction.

[0013] In one possible implementation, the first grating body and the second grating body at least partially overlap in the same distribution area; or, in the same distribution area, the first grating body and the second grating body are staggered.

[0014] In one possible implementation, the first deflection angle varies from 0° to 90°, and the second deflection angle varies from 90° to 0°.

[0015] In one possible implementation, at least two of the grating bodies further include a third grating body, wherein in any one of the distribution regions, the extension direction of the first grating body, the extension direction of the second grating body, and the extension direction of the third grating body are different;

[0016] The extension direction of the third grating body has a third deflection angle with the preset direction, and the third deflection angle of the plurality of third grating bodies gradually changes along the preset direction.

[0017] In one possible implementation, the third deflection angle varies from 45° to 135°.

[0018] In one possible implementation, at least two grating bodies further include a fourth grating body, wherein in any one of the distribution regions, the extension directions of the first grating body, the second grating body, the third grating body, and the fourth grating body are different.

[0019] The extension direction of the fourth grating body has a fourth deflection angle with the preset direction, and the fourth deflection angle of the plurality of fourth grating bodies gradually changes along the preset direction.

[0020] In one possible implementation, the fourth deflection angle varies from 0° to -90°.

[0021] In one possible implementation, at least one of the texture graphics has a minimum size greater than or equal to 3 mm.

[0022] Secondly, this application provides a housing, comprising:

[0023] The microtexture component provided in the first aspect above.

[0024] Thirdly, this application provides an apparatus comprising:

[0025] The housing provided in the second aspect above;

[0026] The device body, and the housing is connected to the device body.

[0027] The micro-textured component provided in this application embodiment uses a base layer to carry the textured graphic, thereby achieving a decorative effect through the textured graphic. Since the textured graphic includes a first grating group and a second grating group, each group includes multiple grating bodies arranged along a preset direction and deflected at an angle to that direction. The continuous change in the deflection angle of these multiple grating bodies achieves a floating light and shadow effect. Because the range of deflection angle change for the first grating group differs from that of the second grating group, the first grating group creates a floating light and shadow effect in one direction, while the second grating group creates a floating light and shadow effect in another direction. The combination of the first and second grating groups allows the textured graphic to exhibit a multi-directional three-dimensional floating effect, enriching the light and shadow layers of the textured graphic and thus improving the three-dimensional dynamic visual effect of the micro-textured component.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0055] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0056] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0057] Currently, there are two main solutions for achieving 3D stereoscopic dynamic lighting and shadow effects. The first is laser holography, which is based on the principles of laser interference and diffraction. It records the three-dimensional image information of an object and reproduces the stereoscopic effect using a specific light source. Although this technology can present high-quality stereoscopic images, it has extremely high requirements for light source, equipment precision, and environmental conditions, resulting in high process complexity, high cost, and difficulty in adapting to large-scale industrial production. In addition, the reproduction of holographic images depends on the illumination of a light source at a specific angle, which is easily affected by ambient light interference in practical applications, leading to unstable visual effects. The second is lenticular stereoscopic printing technology. This technology achieves stereoscopic vision by printing multi-view images on a planar substrate and combining it with a lenticular plate. Specifically, several lenticulars are set on the lenticular plate. The lenticulars selectively reflect light, and the lenticulars with continuously changing angles will selectively reflect light in different directions, thus producing light and shadow movement. However, the stereoscopic effect of the lenticular plates in the existing technology is limited and cannot meet the dynamic visual needs of products.

[0058] In view of the above problems, embodiments of this application provide a micro-textured component, a housing, and a device. The micro-textured component is designed with a first grating group and a second grating group whose deflection angles change continuously, so that the light and shadow movement directions of the first grating group and the second grating group are different, thereby forming a multi-directional light and shadow floating effect in a single plane.

[0059] The following detailed description, in conjunction with the accompanying drawings, illustrates the specific implementation of the microtextured components, housings, and devices provided in the embodiments of this application.

[0060] Reference Figures 1 to 9 As shown, the microtexture component provided in this application embodiment includes a base layer 100 and a plurality of texture patterns 200. The plurality of texture patterns 200 are disposed on the base layer 100. At least one texture pattern 200 includes a first grating group 221a and a second grating group 222a. The first grating group 221a and the second grating group 222a each have a plurality of grating bodies 220 arranged along a preset direction. The grating bodies 220 have a deflection angle with respect to the preset direction.

[0061] In the first grating group 221a, each grating body 220 forms a deflection angle of a different value with respect to a preset direction, thereby causing the deflection angle of the first grating group 221a to gradually change along the preset direction. In the second grating group 222a, each grating body 220 forms a deflection angle of a different value with respect to a preset direction, thereby causing the deflection angle of the second grating group 222a to gradually change along the preset direction. The range of change of the deflection angle of the first grating group 221a is different from the range of change of the deflection angle of the second grating group 222a.

[0062] It should be noted that the gradual change in deflection angle described in this embodiment can be understood as the deflection angle gradually increasing, or it can also be understood as the deflection angle gradually decreasing. This gradual change can be a continuous change or a step-like change.

[0063] The number of grating bodies 220 in the first grating group 221a and the number of grating bodies 220 in the second grating group 222a can be the same.

[0064] At least one texture pattern 200 has multiple distribution areas 210, which are arranged along a preset direction. Each distribution area 210 is provided with at least two grating bodies 220, which include a first grating body 221 and a second grating body 222. In any distribution area 210, the extension direction of the first grating body 221 and the extension direction of the second grating body 222 are different.

[0065] The first grating body 221 has a first deflection angle with the preset direction, and the first deflection angle of the multiple first grating bodies 221 gradually changes along the preset direction. The multiple first grating bodies 221 are arranged along the preset direction to form a first grating group 221a.

[0066] The second grating body 222 has a second deflection angle with the preset direction. The second deflection angle of the multiple second grating bodies 222 gradually changes along the preset direction. The multiple second grating bodies 222 are arranged along the preset direction to form a second grating group 222a.

[0067] The microtextured components of this embodiment can be used in the housing of devices, such as the casing and back cover of smartphones, tablets, wearable devices, etc., thereby improving the aesthetics of the devices.

[0068] In this embodiment, the base layer 100 serves as a carrier, so that a textured pattern 200 can be formed on the base layer 100 through various processes. The textured pattern 200 may include geometric shapes, letters, numbers, Chinese characters, animal and plant patterns, etc., thereby achieving a decorative effect through the textured pattern 200.

[0069] For example, when the texture pattern 200 is circular, multiple distribution areas 210 can be arranged in a circle around the circumference of the circle; or, when the texture pattern 200 is rectangular, multiple distribution areas 210 can be arranged in a circle around the circumference of the rectangle; or, when the texture pattern 200 is a line segment, multiple distribution areas 210 can start from the beginning of the line segment and be arranged along the extension direction of the line segment to the end of the line segment. In this embodiment, no specific shape of a single texture pattern 200 is limited.

[0070] Among the multiple texture graphics 200, at least one texture graphic 200 has floating light and shadow effects in two or more directions, thereby improving the dynamic visual effect of the micro-texture components. The texture graphic 200 has multiple distribution areas 210, which are arranged sequentially along a preset direction, which can be any direction specified by the user.

[0071] For example, refer to Figure 2 and Figure 6 As shown, the preset direction can be any one of the following: X direction, -X direction, Y direction, -Y direction, W direction, -W direction, V direction, and -V direction.

[0072] Since each distribution area 210 has a first grating body 221 and a second grating body 222 with different extension directions, multiple first grating bodies 221 are arranged along a preset direction to form a first grating group 221a. Each first grating body 221 in the first grating group 221a has a first deflection angle with the preset direction. The first deflection angle gradually decreases or increases along the preset direction.

[0073] Multiple second grating bodies 222 are arranged along a preset direction to form a second grating group 222a. Each second grating body 222 in the second grating group 222a has a second deflection angle with respect to the preset direction. The second deflection angle gradually decreases or increases along the preset direction.

[0074] Figure 2 The illustrated texture graphic 200 can be broken down into Figure 4 The schematic first grating group 221a and Figure 5 The second grating group 222a is shown in the diagram. Figure 6 The illustrated texture graphic 200 can be broken down into Figure 8 The schematic first grating group 221a and Figure 9 The schematic second grating group 222a, in Figure 4 and Figure 8 In the first grating body 221, the first grating body 221 extends along the direction from W to -W, and multiple first grating bodies 221 are arranged in rows along the X direction and columns along the Y direction, thereby forming a multi-row, multi-column first grating group 221a. Figure 6 and Figure 9 In the first grating body 221, the first grating body 221 extends along the direction from V to -V, and multiple second grating bodies 222 are arranged in rows along the X direction and columns along the Y direction, thereby forming a multi-row and multi-column second grating group 222a.

[0075] For example, the preset direction can be from -X to X. The extension direction of the first grating body 221 has an angle with the X direction, which is the first deflection angle. Along the X direction, the first deflection angle gradually increases or decreases. The extension direction of the second grating body 222 has an angle with the X direction, which is the second deflection angle. The second deflection angle gradually increases or decreases.

[0076] For example, the preset direction can also be from -Y to Y. The extension direction of the first grating 221 has a first deflection angle with the Y direction, and the first deflection angle gradually increases or decreases along the Y direction. The extension direction of the second grating 222 has a second deflection angle with the Y direction, and the second deflection angle gradually decreases or increases.

[0077] It should be noted that regardless of which preset direction the first grating group 221a and the second grating group 222a move in, the first deflection angle of the first grating group 221a gradually changes along the preset direction, and the second deflection angle of the second grating group 222a also gradually changes. This allows both the first grating group 221a and the second grating group 222a to reflect light, thereby creating a floating light and shadow effect.

[0078] Furthermore, in each distribution area 210, the extension direction of the first grating body 221 is different from that of the second grating body 222. That is, the straight line where the extension direction of the first grating body 221 is located is set at an angle to the straight line where the extension direction of the second grating body 222 is located. This makes the floating direction of the first grating group 221a different from that of the second grating group 222a, thereby making the reflection effect of the first grating group 221a and the second grating group 222a on light different, thus realizing light and shadow displacement in at least two directions, thereby improving the dynamic visual effect of the micro-texture components.

[0079] The micro-textured component provided in this embodiment serves a decorative function by setting a base layer 100 to support the textured pattern 200. Since the textured pattern 200 includes multiple distribution areas 210 arranged along a preset direction, and each distribution area 210 is provided with a first grating body 221 and a second grating body 222 extending in different directions, when multiple first grating bodies 221 with continuously changing first deflection angles are arranged to form a first grating group 221a, the first grating group 221a can create a light and shadow floating effect in one direction. When multiple second grating bodies 222 with continuously changing second deflection angles are arranged to form a second grating group 222a, the second grating group 222a can create a light and shadow floating effect in another direction. The first grating group 221a and the second grating group 222a combined together allow the textured pattern 200 to exhibit a three-dimensional floating effect in multiple directions, thereby enriching the light and shadow layers of the textured pattern 200 and improving the three-dimensional dynamic visual effect of the micro-textured component.

[0080] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments, the first grating body 221 and the second grating body 222 at least partially overlap in the same distribution area 210. That is, Figure 4 The schematic first grating group 221a and Figure 5 After the second grating group 222a is superimposed as shown in the diagram, the result is... Figure 2 The illustrated texture pattern 200 is formed by the gradual deflection of each first grating body 221 of the first grating group 221a along a preset direction, thereby forming a light and shadow displacement in one direction. The second grating group 222a gradually deflects along a preset direction, thereby forming a light and shadow displacement in another direction. When the first grating group 221a and the second grating group 222a are combined to form the texture pattern 200, the texture pattern 200 has light and shadow displacement in two directions, thereby giving the texture pattern 200 a three-dimensional floating visual effect.

[0081] Reference Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, in some embodiments, the first grating body 221 and the second grating body 222 are staggered within the same distribution area 210. That is, Figure 8 The schematic first grating group 221a and Figure 9 After the second grating group 222a is assembled as shown in the diagram, the result is... Figure 6 The schematic texture graphic 200, in this configuration, each distribution area 210 may include two distribution sub-regions 211, one distribution sub-region 211 having a first raster body 221, and the other distribution sub-region 211 having a second raster body 222. Of course, in... Figures 2 to 5 In the schematic scheme, each distribution area 210 may also include two distribution sub-regions 211. Since the two distribution sub-regions 211 are superimposed, the first grating body 221 and the second grating body 222 are superimposed, and they are no longer separated.

[0082] In this way, each of the first grating bodies 221 of the first grating group 221a gradually deflects along a preset direction, thereby forming a light and shadow displacement in one direction. The second grating group 222a gradually deflects along a preset direction, thereby forming a light and shadow displacement in another direction. When the first grating group 221a and the second grating group 222a combine to form a texture pattern 200, the texture pattern 200 has light and shadow displacement in two directions, thereby having a three-dimensional floating visual effect.

[0083] In one possible implementation, the first deflection angle varies from 0° to 90°, and the second deflection angle varies from 90° to 0°.

[0084] For example, Figure 10 and Figure 11 The diagram illustrates the correspondence between the change in the deflection angle of the grating 220 and the direction of light and shadow movement. Along the X-direction, as the deflection angle changes, the light and shadow exhibit variations in brightness. Figure 10 Corresponding to the first grating group 221a, when the first deflection angle of the first grating group 221a gradually increases between 0° and 90° along the X direction, a light and shadow variation effect is formed. Figure 11 Corresponding to the second grating group 222a, when the second deflection angle of the second grating group 222a gradually decreases between 90° and 0° along the X direction, another light and shadow change effect will be formed. The first grating group 221a and the second grating group 222a are superimposed or combined to form two light and shadow change effects, thereby forming a three-dimensional dynamic visual effect.

[0085] In one possible implementation, at least two grating bodies 220 further include a third grating body, and in any distribution region 210, any two of the extension directions of the first grating body 221, the second grating body 222, and the third grating body are different.

[0086] The extension direction of the third grating body has a third deflection angle with the preset direction. The third deflection angle of multiple third grating bodies gradually changes along the preset direction. Multiple third grating bodies are arranged along the preset direction to form a third grating group.

[0087] It is understandable that, based on setting the first grating group 221a and the second grating group 222a, a third grating group can also be set. Since the extension direction of the third grating body is different from the extension direction of the first grating body 221, and also different from the extension direction of the second grating body 222, the first grating group 221a, the second grating group 222a and the third grating group each have different floating directions. This results in the first grating group 221a, the second grating group 222a and the third grating group each forming different light and shadow effects, thereby making the texture graphic 200 rich in light and shadow layers and the visual effect dynamic and three-dimensional.

[0088] In each distribution region 210, any two of the first grating body 221, the second grating body 222, and the third grating body can partially overlap or partially offset, or the first grating body 221, the second grating body 222, and the third grating body can partially overlap or partially offset, or all three of the first grating body 221, the second grating body 222, and the third grating body can be offset. This embodiment does not impose any restrictions on this.

[0089] In some embodiments, the third deflection angle varies from 45° to 135°.

[0090] This setting allows the range of the third deflection angle to be staggered from the range of the first deflection angle and the range of the second deflection angle, which in turn helps the third grating group to increase the sense of layering of light and shadow changes based on the first grating group 221a and the second grating group 222a.

[0091] In one possible implementation, at least two grating bodies 220 further include a fourth grating body, wherein in any distribution region 210, any two of the extension directions of the first grating body 221, the second grating body 222, the third grating body, and the fourth grating body are different.

[0092] The fourth grating body has a fourth deflection angle between its extension direction and the preset direction. The fourth deflection angle of multiple fourth grating bodies gradually changes along the preset direction. Multiple fourth grating bodies are arranged along the preset direction to form a fourth grating group.

[0093] With this configuration, a fourth grating group is added on top of the first grating group 221a, the second grating group 222a, and the third grating group. Since the extension direction of the fourth grating body in a single distribution area 210 is different from the extension directions of the first grating body 221, the second grating body 222, and the third grating body, the fourth grating group composed of multiple fourth grating bodies can form a light and shadow floating effect that is different from that of the first grating group 221a, the second grating group 222a, and the third grating group, thereby enriching the dynamic layers of the texture graphics 200. Moreover, this configuration is also highly feasible in terms of manufacturing process.

[0094] In some embodiments, the fourth deflection angle varies from 0° to -90°. For example, when multiple first grating bodies 221, multiple second grating bodies 222, multiple third grating bodies, and multiple fourth grating bodies are all arranged along the X direction, the angle between the first grating body 221 and the X direction is the first deflection angle, the angle between the second grating body 222 and the X direction is the second deflection angle, the angle between the third grating body and the X direction is the third deflection angle, and the angle between the fourth grating body and the X direction is the fourth deflection angle.

[0095] In this way, the range of the fourth deflection angle is set differently from the range of the first deflection angle, the range of the fourth deflection angle is set differently from the range of the second deflection angle, and the range of the fourth deflection angle is set differently from the range of the third deflection angle. This allows the fourth grating group to have a floating direction that is different from that of the first grating group 221a, the second grating group 222a, and the third grating group. This is beneficial for the fourth grating group to enrich the light and shadow layers on the basis of the first grating group 221a, the second grating group 222a, and the third grating group.

[0096] In one possible implementation, the minimum size of at least one textured graphic 200 is greater than or equal to 3 mm.

[0097] It should be noted that the texture graphic 200 can be a regular two-dimensional graphic or an irregular two-dimensional graphic. On the plane where the texture graphic 200 is located, the smallest of the various dimensions of the texture graphic 200 can be considered as the minimum size of the texture graphic 200.

[0098] Since the texture graphic 200 is provided with a first grating group 221a and a second grating group 222a, and even a third and a fourth grating group, when the minimum size of the texture graphic 200 is less than 3 mm, there will not be enough space to simultaneously arrange the first grating group 221a and the second grating group 222a, or the arrangement density of the first grating body 221 will be insufficient, and the arrangement density of the second grating body 222 will be insufficient, making it impossible for the first grating group 221a and the second grating group 222a to present their respective light and shadow transformation effects, and the three-dimensional effect will not be obvious. Therefore, in this embodiment, the minimum size of the texture graphic 200 should be greater than or equal to 3 mm to ensure that the first grating group 221a and the second grating group 222a can present light and shadow effects in different directions after being combined, so that the combination of the first grating group 221a and the second grating group 222a can improve the dynamic visual effect of the texture graphic 200.

[0099] It should be understood that the cross-sectional shape of the grating body 220 in this embodiment can be, but is not limited to, an arc shape, a triangle, a quadrilateral, a trapezoid, a regular polygon, or an irregular polygon, for example... Figure 1 The diagram illustrates a scheme where the cross-sectional shape of the grating 220 is semi-circular. Figure 12 The diagram illustrates a scheme where the cross-sectional shape of the grating 220 is triangular.

[0100] The height H of the grating body 220 is within 30 μm, the width L of the grating body 220 ranges from 1 μm to 200 μm, the distribution sub-region 211 can be rectangular or circular, the side length or diameter of the distribution sub-region 211 is about 0.1 mm, and the grating body 220 will not exceed the distribution sub-region 211.

[0101] The following combination Figures 13 to 16 A microtextured component is designed according to the solution provided in the foregoing embodiments and applied to a smartphone.

[0102] The texture graphics 200 of multiple squares on the microtexture component can be randomly divided into two groups, and the lighting and shadow changes of the two groups of squares can be made to be different. For example, here we take the lighting and shadow changes of the two groups of squares in opposite directions, with the lighting and shadow of one group of squares moving from -X to X, such as... Figure 14 As shown, the light and shadow of another set of blocks move from X to -X, as... Figure 15 As shown, a clear shift in light and shadow occurs between the two sets of blocks, creating a visually three-dimensional floating effect.

[0103] Next, grayscale gradient effects were designed for the two sets of cubes, with different grayscale levels corresponding to different deflection angles. The black-and-white gradient effect corresponded to the deflection angle variation of the raster volume 220. For example, Figure 10 The gradient effect of the first grating group 221a shown is from white to black. Figure 11 The gradient effect of the second grating group 222a shown is from black to white.

[0104] according to Figure 10 and Figure 11 The illustrated scheme designs one set of blocks from black to white, with a first deflection angle ranging from 0° to 90°, and another set of blocks from white to black, with a second deflection angle ranging from 90° to 0°. In this way, the deflection angle ranges of the two sets of blocks are opposite, corresponding to two opposite directions of light and shadow effects. By combining or superimposing these two sets of blocks, a micro-texture graphic 200 can simultaneously have blocks with two floating directions, thus achieving effects such as... Figure 13 and Figure 16 The 200 micro-texture graphics shown create a 3D floating effect. Figure 13 The schematic diagram of multiple micro-texture graphics 200 can be derived from Figure 14 and Figure 15 The illustration shows the combination of 200 individual micro-texture graphics.

[0105] The following is a brief description of the fabrication process for micro-textured components.

[0106] A grayscale image is designed based on the changing effect of the micro-texture pattern 200. The grayscale image is then input into the direct-write lithography machine. The lithography machine automatically adjusts the lithography energy value according to the grayscale value corresponding to the grayscale image, and completes the lithography work on the photoresist-coated photomask.

[0107] After photolithography, the photomask undergoes development, cleaning, and drying processes. Through these processes, the texture pattern 200 is fabricated onto the photomask, which can then be reused as a mold. Subsequently, this three-dimensional floating texture pattern 200 can be reproduced on substrate layers 100 of different materials using various processing techniques such as UV transfer, in-mold injection molding, chemical etching, and electroforming, thereby forming the micro-textured component of this embodiment. For example, the substrate layer 100 can be glass, ceramic, metal, polymer composite material, etc., and this application does not impose any limitations on this.

[0108] Based on the above embodiments, this application also provides a housing, which includes microtextured components. The structure and working principle of the microtextured components have been described in detail in the foregoing embodiments and will not be repeated here.

[0109] For example, a micro-textured pattern 200 is copied onto a PET explosion-proof film using UV transfer printing. Then, specific colors are applied through processes such as coating and printing. Next, the PET explosion-proof film is cut into a shape consistent with the equipment using laser cutting, thus forming a micro-textured component. This micro-textured component is then bonded to the glass using a positioning and bonding process. Through these steps, a pattern with a three-dimensional floating grating is created on the glass. In this solution, the PET explosion-proof film is equivalent to the base layer 100, and the glass is equivalent to the housing body.

[0110] For example, a UV transfer process can be used to copy the textured graphic 200 onto the surface of a composite board (such as a PC composite board or a fiberglass composite board). Then, specific colors can be applied through processes like coating and printing. Next, a hot bending process can be used to process the composite board into a shape with a certain 3D structure. Finally, a cutting process can be used to process the composite board with the 3D structure into a size and shape suitable for the equipment, and it can then be applied to the equipment. In this solution, the composite board is equivalent to the base layer 100 and also to the shell body; that is, the base layer 100 and the shell body are integrated into one.

[0111] For example, the texture pattern 200 can be processed onto the glass surface through glass etching. Specifically, a layer of photoresist is first applied to the already formed glass surface, then exposed and developed using a mask, followed by an etching process to form the texture pattern 200 on the glass surface. Finally, a specific color is given to the product through processes such as coating and printing. In this solution, the glass is equivalent to the substrate 100 and also to the shell body; that is, the substrate 100 and the shell body are integrated into one.

[0112] Glass etching textures are divided into wet etching and dry etching. The main difference lies in the different chemical reagents used for etching. Wet etching uses liquid etchant, while dry etching uses gaseous plasma. Other principles are basically the same.

[0113] Because the texture pattern 200 can change the stress distribution on the glass surface, it can increase the strength of the glass and make it less prone to breakage. At the same time, this slightly uneven micro-textured pattern 200 can reduce the contact area when the hand touches it, thereby effectively reducing the residue of liquid or fingerprints on the glass surface and keeping the casing clean during long-term use.

[0114] In specific implementation, different processing methods can be adopted as needed. This application embodiment does not limit this, as long as it can form texture graphics 200 with different floating directions.

[0115] Based on the above embodiments, this application provides a device including a housing and a device body, wherein the housing is connected to the device body. The structure and working principle of the housing have been described in detail in the foregoing embodiments and will not be repeated here.

[0116] For example, the device can be a smartphone, tablet, wearable device, refrigerator, etc.

[0117] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
