[0023] Specific embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It will be understood that the specific embodiments described herein are merely exemplary and explanatory of the present disclosure and are not intended to limit the present disclosure.

[0024] In this disclosure, location words such as "inner and outer" are used relative to the contours of the corresponding components themselves, unless otherwise specified. Furthermore, unless otherwise indicated, when the following description refers to the drawings, identical numbers in different drawings represent identical or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments compatible with the present disclosure. Rather, they are merely examples of devices and methods compatible with some aspects of the present disclosure, as detailed in the appended claims.

[0025] According to a first aspect of the present disclosure, a decorative member is provided that can be disposed on various products to improve their aesthetics. For example, the decorative member can serve as a housing for an electronic device to create desired light and shadow effects. Specifically, referring to FIGS. 1 and 2 , the decorative member includes a substrate 1 and a first texture layer 2 disposed on the substrate 1. Here, the substrate 1 may be made of a transparent material having a certain refractive index, such as a PC (polycarbonate) sheet, a PET (polyethylene terephthalate) sheet, or a PC / PMMA (polymethyl methacrylate) composite sheet, and the substrate 1 may be a glass plate. Of course, a substrate 1 made of an opaque material can also be applied to the decorative member of the present disclosure without affecting the presentation of the effect of the first texture layer 2.

[0026] As shown in FIGS. 1 and 2 , the first texture layer 2 has multiple preset paths, each of which has multiple lattice portions 3 arranged in sequence to congruently create a hairline shape. The width of the hairline can be determined by the size and number of the lattice portions 3. For example, referring to FIG. 10 , the outline of the arrangement of the partial lattice portions 3 of a single hairline is roughly depicted by a thick black line in FIG. 10 , and the extension direction outlined by the thick black line can be understood as a preset path. In FIG. 10 , the area between two adjacent thick black lines represents the arrangement of the partial lattice portions 3 of a single hairline. As shown in FIG. 10 , a single hairline can be composed of multiple rows of multiple lattice portions 3 arranged on a preset path to form a thicker hairline effect. In another embodiment, only one row of lattice portions 3 can be arranged on a preset path to form a thinner hairline effect. FIG. 2 has a reduced view effect compared to FIG. 10 , but only the partial texture layer is shown without showing the entire hairline. In FIG. 2, multiple consecutive pixel grids form a single hairline on a preset path. The lattice portion 3 in FIG. 2 forms multiple hairlines on multiple preset paths, thus creating hairline light and shadow effects. In FIG. 2, hairlines with wider pixel grids are formed by multiple rows of lattice portions, while hairlines with thinner pixel grids are formed by a single row of lattice portions. Together with FIG. 6, FIG. 6 illustrates the light and shadow effects when the lattice portion 3 is observed at the same viewing angle. From left to right, as the placement angle of the lattice portion 3 changes, the light and shadow reflected by the lattice portion 3 at the same viewing angle changes from dark to light. However, it should be noted that this is not limited to the effects shown in FIG. 6, which shows only one viewing angle as an example, but that the corresponding light and shadow effects also change when such a lattice portion 3 is viewed from other viewing angles.10, in an embodiment of the present disclosure, the lattice portions 3 on two adjacent preset paths (i.e., the two paths depicted by three thick black lines in FIG. 10) are arranged at different angles, and the lattice portion 3 on the path closer to the right of the two paths depicted in FIG. 10 is rotated approximately 45° relative to the lattice portion 3 on the path on the left, which is merely illustrative and is not intended to limit the present disclosure. In other words, the adjacent lattice portions 3 constituting two adjacent hairlines are arranged at different angles, so that when viewed at the same viewing angle, the two adjacent hairlines can have different light and shadow effects.

[0027] According to the above technical solution, multiple grid sections 3 are arranged along a preset path to create a hairline effect, making the display effect of hairline light and shadow more natural and less rigid. Furthermore, the grid sections 3 of adjacent hairlines are arranged at different angles, resulting in different light and shadow effects on two adjacent hairlines. While the boundaries between the hairlines are clear, the hairlines can also be flashed alternately at different viewing angles, thereby improving the flexibility and aesthetics of the decorative element.

[0028] In an embodiment of the present disclosure, referring to FIG. 3, the surface of the substrate 1 is divided into a plurality of unit cell areas 4 of the same size, and each of the unit cell areas 4 is filled with one of the lattice portions 3. Here, the unit cell areas 4 are constructed to facilitate the placement of the lattice portions 3 during design, and the boundaries of the unit cell areas 4 are not visible in the finished decorative member. Each of the unit cell areas 4 is placed together with the lattice portions 3 through this placement, and therefore the transition of the light and shadow effect finally provided is consistent and natural.

[0029] Further, referring to FIG. 4, the unit cell area 4 may be square, and the center of each lattice section 3 may be located at the center of the square, i.e., the center of the lattice section 3 coincides with the center of the square. The lattice section 3 may extend to and connect to the inscribed circle 41 of the square. In this way, it is possible to ensure that each lattice section 3 has the same size, thereby displaying a more uniform light and shadow effect. Among them, the inscribed circle 41 and the aforementioned square are constructed together to facilitate the placement of the lattice sections 3 during design, and the boundary between the two is not displayed in the finished decorative member.

[0030] In another embodiment, each of the lattice sections 3 can also be arranged to connect to the edge of the unit cell area 4, as shown in Figure 3, making the light and shadow effect coherent and smooth, thus having a natural flow effect.

[0031] According to one embodiment of the present disclosure, the side length of the square can be set to 40 to 100 microns, for example 50 microns. By defining the unit cell area 4 to this size, the size of the lattice portion 3 within the unit cell area 4 can also ensure a natural flow effect of light and shadow, on the premise that it is technically easy to realize.

[0032] According to one embodiment of the present disclosure, the tangent value of the included angle α (see FIG. 3 ) may be between 1:30 and 4:1, where the included angle is between each reflective surface of the grating portion 3 and the surface of the substrate 1. For example, when the grating portion 3 is an equilateral triangular prism as shown in FIG. 3 , if the height of the grating portion 3 (i.e., the size of the grating portion 3 in the direction perpendicular to the surface of the substrate 1) is 0.5 microns, the corresponding width of the grating portion 3 (i.e., the width of the surface where the triangular prism is bonded to the substrate 1) may be 30 microns. This range of tangent values ​​can avoid providing only a flat effect due to excessive width and avoiding a non-tilted reflective surface due to insufficient width.

[0033] 7 and 8, in one embodiment, the height H of each of the lattice segments 3 may be 0.5 microns to 20 microns, and the width W of each cross section of the lattice segments 3 may be 10 microns to 50 microns, the cross section being perpendicular to the corresponding preset path. A continuous flowing hairline light and shadow effect can be achieved with the lattice segments 3 within this size range. Furthermore, arranging the lattice segments 3 of this size within a unit cell area that is a square with a side length of 50 microns helps to obtain better light and shadow effects.

[0034] In one embodiment, the size of the lattice portion 3 can be determined according to the side length of the square, for example, the width of the cross section of the lattice portion 3 can be 20% to 60% of the side length of the square, for example 50% of the side length of the square, and the cross section is perpendicular to the corresponding preset path. For example, when the side length of the square is 50 microns, the width of the lattice portion 3 can be 10 to 30 microns, such as 20 microns. This arrangement can achieve clear and visible light and shadow effects without being blurred due to an excessively large size or invisible due to an excessively small size.

[0035] In embodiments of the present disclosure, at least some of the lattice segments 3 on each of the preset paths are arranged at different angles. By arranging the lattice segments 3 at different angles, the lattice segments 3 change with the effect of the hairline flow, achieving a hairline flow effect. In some embodiments, to achieve a flowing light and shadow effect, adjacent lattice segments along the preset path can be divided into groups, and the preset path can be divided into multiple groups of lattices. The angles of the lattice segments 3 within each group can be the same, and the angles of the lattice segments in adjacent groups can be set differently. In this way, lattice segments 3 with the same angle within the same group are used to create the hairline light and shadow, and varying the angles of the lattice segments between different groups can provide light and shadow with different intensities to create a flowing hairline effect. For example, in some embodiments, the arrangement angles of the lattice segments along the preset path of the hairline can be as follows: the arrangement angle of the group of lattice segments 3 at the starting end (here, all angles are relative to the vertical lattice) is 10°, and the arrangement angle of the group of lattice segments 3 at the end is 80°. The grid groups between the start and end points can be sequentially changed within an angle range. This arrangement can create a flowing hairline effect. That is, when viewed from a certain viewpoint, different light and dark effects are sequentially applied to a single hairline within a preset path (as shown in FIG. 1), thus creating a flowing hairline texture. When the hairline angle is between 10° and 80°, the angles of the two hairlines can be between 20° and 90° and between 0° and 70°, respectively, with the two hairlines adjacent to and on either side of the hairline. Here, the angles of the adjacent hairlines and the angle of the single hairline are described as examples only; in actual applications, they can be adjusted according to the desired light and shadow effects.

[0036] In one embodiment of the present disclosure, the lattice portion 3 can include at least one of a linearly extending lattice portion 3 and a curvedly extending lattice portion 3. The linearly extending lattice portion 3 can be, for example, the lattice portion 3 shown in FIGS. 3 to 5, while the curvedly extending lattice portion 3 can be, for example, an S-shaped extension, an arc-shaped extension, etc. In an embodiment of the present disclosure, referring to FIGS. 7 to 9, the lattice portion 3 can include at least one of a curved lattice portion 31 having a reflective surface configured as a curved surface and a flat lattice portion 32 having a reflective surface configured as a flat surface. For example, in a decorative member, the first texture layer 2 can include one of the aforementioned lattice portions or a combination of various lattice portions, and the types of lattice portions 3 on the same preset path can be the same or different. The curved reflective surface can reflect light from various angles and has slightly weaker reflective brightness than a flat reflective surface. In practical applications, the configuration of the lattice portions 3 of the first texture layer 2 can be set according to the desired light and shadow effect.

[0037] In some embodiments, as shown in FIG. 9, the curved grating portion 31 can include a grating portion having a cross section configured as an arc, where the cross section is perpendicular to the corresponding preset path. The arc surface has several tangents that can reflect light from different angles, thus creating a softer light and shadow effect. As shown in FIGS. 7 and 8, the planar grating portion 32 can include a grating portion having a cross section configured as a triangular shape, where the cross section is perpendicular to the corresponding preset path. Because the reflective surface of this grating portion is flat, the reflective brightness is higher than that of an arc shape, resulting in a brighter effect. In the embodiments of the present disclosure, the cross-sectional shape of the grating portion 3 is not limited thereto and will not be described in detail herein.

[0038] In some embodiments, referring to FIG. 7 , the planar lattice portion 32 can include a rectangular lattice portion having a cross section configured as a right-angled triangle, the cross section being perpendicular to the corresponding preset path. In one embodiment of the present disclosure, the first texture layer 2 of the decorative member can be arranged adjacent to the rectangular lattice portions on multiple adjacent preset paths, with the hypotenuses of the adjacent rectangular lattice portions arranged in the same direction. The right-angle sides of adjacent rectangular lattice portions are attached to the substrate 1, and the other right-angle sides are adjacent to the hypotenuses of the adjacent rectangular lattice portions. In this manner, multiple rectangular lattice portions are arranged adjacent to each other to create an effect similar to a Fresnel lens, and the light and shadow effects provided are transparent. In an embodiment of the present disclosure, the combination of multiple lattice portions 3 is arranged according to the light and dark requirements of the light and shadow, so that the light and shadow effects provided by the decorative member are natural and not rigid.

[0039] In one embodiment, a second texture layer having a different effect from the first texture layer 2 can be further disposed on the surface of the substrate 1. In some embodiments, the first texture layer 2 and the second texture layer can be disposed in different areas of the substrate 1, for example, the substrate 1 is divided into two areas, the first texture layer 2 is disposed in one area, and the second texture layer is disposed in the other area, so that two types of light and shadow effects can be provided on the decorative member, which have peculiarity. Similarly, the substrate 1 can be divided into three or more areas, and each area can be disposed with a different texture layer. In some embodiments, the first texture layer 2 and the second texture layer can be disposed over the entire surface of the substrate 1 and arranged in a cross-like manner, i.e., after the first texture layer 2 and the second texture layer are arranged in a cross-like manner, a new light and shadow effect can be provided. Furthermore, it should be noted that in the embodiments of the present disclosure, a combination of the above two methods can be adopted, i.e., a part of the first texture layer 2 and other texture layers can be arranged in the same area and arranged in a cross manner, and other parts of the first texture layer 2 can be arranged independently from the texture layers in other areas, so as to give the decorative member various light and shadow effects.

[0040] According to a second aspect of the present disclosure, a housing for an electronic device is also provided. The housing for the electronic device includes the decorative member described above and has all the beneficial effects of the decorative member described above, but not described herein.

Of course, other functional layers can be added or more decorative members can be layered according to actual needs.

[0041] According to a third aspect of the present disclosure, there is further provided an electronic device, which includes a housing of the aforementioned electronic device to improve visual effects, among which the electronic device includes, but is not limited to, a mobile phone, a tablet, a laptop, etc.

The method for preparing a decorative member product includes the following steps: texture parameters are set by software, a preset texture is engraved on a mold by a laser, and the mold is subjected to exposure, development, drying, plasma cleaning, and other operations to obtain a texture mold; the texture mold is subjected to transfer and curing operations to obtain a transfer mold; the texture is transferred to a substrate 1, and an optical texture layer is transferred onto the substrate 1; a coating layer is deposited on the optical texture layer, and an ink layer is printed on one side of the coating layer; and then the thin film of the decorative member is attached to glass by a process such as bonding, to produce a glass product with a decorative member. In another method, a preset texture can be applied to a glass product with a homogeneous photoresist, and a preset texture structure can be obtained by photolithography, exposure, and development; the glass with the texture layer is placed in an etching tank, and the texture is completely replicated on the glass through a reasonable etching time, forming the decorative member in the present disclosure, where a glass plate is used as the substrate 1; then, photocoating can be performed on the side opposite to the texture layer of the glass; an ink layer is sprayed on one side of the coating layer, thereby obtaining a product with a decorative member.
