[0016] See Figures 1, 2, 3, and 7. The present application provides a decorative member 10. The decorative member 10 includes a substrate 100 and a lattice layer 200 disposed on the substrate 100. The lattice layer 200 includes a plurality of first texture regions 210. At least some of the plurality of first texture regions 210 are formed by superimposing and combining M lattice patterns 300 based on a predetermined relationship, and each lattice pattern 300 includes a plurality of lattice regions 310 arranged at intervals. The lattice angles of the lattice regions 310 on at least two of the M lattice patterns 300 are different.
[0017] At least one lattice region 310 in the (N+1)th lattice pattern 300 is overlapped with at least one lattice region 310 in the Nth lattice pattern 300, and the lattice angle a of the lattice region 310 in the Nth lattice pattern 300, the lattice angle b of the lattice region 310 in the (N+1)th lattice pattern 300, and the lattice angle c of the overlapping region 310c between the lattice region 310 in the (N+1)th lattice pattern 300 and the lattice region 310 in the Nth lattice pattern 300 satisfy a predetermined relationship: c = X × a + Y × b, where N and M are integers and 1≦N≦M−2. X is represented as a first weight, and Y is represented as a second weight. When the lattice angle a of the lattice region 310 in the Nth lattice pattern 300 is different from the lattice angle b of the lattice region 310 in the (N+1)th lattice pattern 300, the first weight and the second weight satisfy 0.8≦X+Y≦1. In some embodiments, the sum of the first weight and the second weight may be 0.8, 0.85, 0.9, 0.95, 1, etc.
[0018] In the decorative member 10 of the present application, a lattice layer 200 is disposed on the substrate 100. The lattice layer 200 includes a plurality of first texture regions 210. At least some of the plurality of first texture regions 210 are formed by overlapping and combining M lattice patterns 300 based on a predetermined relationship. Because the decorative member 10 has different shading effects at different positions, the shading effect of the decorative member 10 has a clearer sense of spatial hierarchy and three-dimensionality. For example, the number M of lattice patterns 300 may be 5 to 15, thereby providing a stronger spatial hierarchy and a clearer, more distinctive, and more orderly shading effect of the decorative member 10. In some embodiments, the number M of lattice patterns 300 may be 8 to 10. In some embodiments, the number M of lattice patterns 300 may be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, etc. The specific number M of the grid patterns 300 may be specifically set according to the actual needs of the decorative member 10, and is not particularly limited in the present application.
[0019] For example, in this embodiment, the preset relationship may be that M grid patterns 300 are superimposed and combined in order. For example, the second grid pattern 300 is superimposed on the first grid pattern 300, the third grid pattern 300 is superimposed on the combined grid pattern formed by superimposing and combining the second grid pattern 300 and the first grid pattern 300, and so on until the Mth grid pattern 300 is superimposed on the (M-1)th grid pattern 300. In another embodiment, for example, the second grid pattern 300 is superimposed on the first grid pattern 300, the third grid pattern 300 is superimposed on the combined grid pattern formed by superimposing and combining the second grid pattern 300 and the first grid pattern 300, and so on until M grid patterns 300 are superimposed on the combined grid pattern formed by superimposing and combining the (M-2)th grid pattern 300 and the (M-1)th grid pattern 300. In this manner, M grid patterns 300 are sequentially superimposed and combined to form grid layer 200. In some embodiments, the predetermined relationship may further be that M grid patterns 300 include a plurality of pattern modules. At least one of the pattern modules includes at least two grid patterns 300. When grid patterns 300 in a pattern module are sequentially superimposed and combined, the pattern modules are sequentially superimposed and combined. For example, when M is 7, seven grid patterns 300 may include a first pattern module, a second pattern module, and a third pattern module. The first pattern module includes one grid pattern 300. The second pattern module includes two grid patterns 300. The third pattern module includes four grid patterns 300.When the two grating patterns 300 in the second pattern module are sequentially superimposed and combined, and the four grating patterns 300 in the third pattern module are sequentially superimposed and combined, the first pattern module, the second pattern module, and the third pattern module are sequentially superimposed and combined to form the grating layer 200.
[0020] Please refer to Figures 4, 5, 6, and 7. Figure 4 is a structural diagram of the Nth lattice pattern 300, Figure 5 is a structural diagram of the (N+1)th lattice pattern 300, and Figure 6 is a structural diagram of the (N+1)th lattice pattern 300 and the Nth lattice pattern 300 superimposed and combined based on a preset relationship. Specifically, the lattice region 310 in the Nth lattice pattern 300 is a first lattice region 310a, and the Nth lattice pattern 300 includes a plurality of first lattice regions 310a arranged at intervals. The lattice region 310 in the (N+1)th lattice pattern 300 is a second lattice region 310b, and the (N+1)th lattice pattern 300 includes a plurality of second lattice regions 310b arranged at intervals.
[0021] See Figures 7 and 8. The grating region 310 includes a plurality of grating structures 312 arranged at intervals. The grating structures 312 may be configured as protrusions on the substrate 100. The grating width D of the grating structures 312 is 30 μm to 60 μm, and the grating height H of the grating structures 312 is 0.5 μm to 20 μm. In some embodiments, the grating width D of the grating structures 312 may be 30 μm, 40 μm, 50 μm, 60 μm, etc., and the grating height H of the grating structures 312 may be 0.5 μm, 1 μm, 5 μm, 10 μm, 10 μm, 20 μm, etc. In some embodiments, when the grating structures 312 are configured as grooves on the substrate 100, the grating width D of the grating structures 312 may be the width of the grooves, and the grating height H of the grating structures 312 may be the depth of the grooves.
[0022] In this embodiment, the lattice structure 312 is configured as a linear lattice structure. For example, the lattice angle of the lattice region 310 may be the included angle between the extension direction of the lattice structure 312 and a specific reference line. For example, the lattice angle of the lattice region 310 may be the included angle between the extension direction of the lattice structure 312 and the horizontal or vertical direction. In another example, the lattice angle of the lattice region 310 may be the included angle between the extension direction of the lattice structure 312 and the extension direction of one side of the base 100. For example, the base 100 may have a rectangular shape, and the lattice angle of the lattice region 310 may be the included angle between the extension direction of the lattice structure 312 and the extension direction of one of the four sides of the base 100. The lattice angle of the lattice region 310 may be between 0° and 180°, which allows for more diverse lattice angles in the lattice layer 200, thereby enriching the shading effect of the decorative member 10 and allowing the shading effect of the decorative member 10 to have a sense of spatial hierarchy and three-dimensionality across a wide viewing angle. It should be understood that the lattice angle of the lattice region 310 can have similar or identical shading effects when it is between 180° and 360° and when it is between 0° and 180°. In some embodiments, the lattice angle of the lattice region 310 may be set to a smaller range, thereby allowing the decorative member 10 to have a more distinct shading effect within a specific angle range. For example, the lattice angle of the lattice region 310 may be between 0° and 90°, between 30° and 120°, etc. In this embodiment, a structure 312 may also be configured as a curved lattice structure, a polygonal lattice structure, etc.
[0023] In this embodiment, the lattice angles of at least two lattice regions 310 in each of the M lattice patterns 300 are different. Specifically, the lattice angles of at least two first lattice regions 310a in the plurality of first lattice regions 310a are different, and the lattice angles b of at least two second lattice regions 310b in the plurality of second lattice regions 310b are different. In some embodiments, the lattice angles of the plurality of lattice regions 310 in each lattice pattern 300 are the same.
[0024] See Figures 2 and 7. The (N+1)th lattice pattern 300 is superimposed on the Nth lattice pattern 300. The second lattice region 310b and the first lattice region 310a are superimposed to form an overlapping region 310c. The lattice angle a of the first lattice region 310a, the lattice angle b of the second lattice region 310b, and the lattice angle c of the overlapping region 310c satisfy a predetermined relationship: c = X × a + Y × b. Because the lattice regions 310 located at different positions on the lattice layer 200 have different lattice angles, it can be seen that the brightness levels of different lattice regions 310 vary with different viewing angles. The presence of concentrated light and dark regions on the decorative member 10 creates a hierarchical and three-dimensional shading effect on the decorative member 10. Furthermore, in the present application, the lattice layer 200 is formed by superimposing and synthesizing M lattice patterns 300, so that the decorative member 10 in the present application can achieve a shading effect by superimposing multi-layered textures with a single lattice layer 200, and the manufacturing process of the decorative member 10 is simple, without the need for a complicated texture joining process.
[0025] In this embodiment, the lattice angle a of the lattice region 310 in the Nth lattice pattern 300 is different from the lattice angle b of the lattice region 310 in the (N+1)th lattice pattern 300, and the first weight and the second weight satisfy 0.8≦X+Y≦1, so that the lattice angle a of the first lattice region 310a, the lattice angle b of the second lattice region 310b, and the lattice angle c of the overlapping region 310c are different from each other, and the decorative member 10 has more diverse shading effects. In some embodiments, when the lattice angle a of the lattice region 310 in the Nth lattice pattern 300 is the same as the lattice angle b of the lattice region 310 in the (N+1)th lattice pattern 300, the first weight and the second weight satisfy 0.8≦X+Y≦1, and the lattice angle c of the overlap region 310c is different from the lattice angle a of the first lattice region 310a and the lattice angle b of the second lattice region 310b.
[0026] For example, in this embodiment, the second weight is equal to or greater than the first weight in at least a portion of the first texture region 210. For example, the first weight may be 0.3, and the second weight may be 0.7, so that the lattice angle c of the overlap region 310c in the lattice layer 200 is closer to the lattice angle b of the second lattice region 310b, making the texture effect of the lattice pattern 300 in the lattice layer 200 farther from the substrate 100 more obvious and creating a gradual depth effect. Therefore, the spatial hierarchy of the decorative member 10 becomes more obvious. In some embodiments, both the first weight and the second weight may be 0.5, so that the shading effect of the decorative member 10 becomes more uniform and the spatial hierarchy of the decorative member 10 is improved. In some embodiments, the specific values of the first weight and the second weight may be specifically set according to the actual needs of the decorative member 10 and are not particularly limited in this application. For example, the first weight may be 0.4, 0.2, 0.15, 0.1, etc., and the second weight may be 0.6, 0.8, 0.85, 0.9, etc.
[0027] In some embodiments, the sum of the first weight and the second weight is less than 1, and the lattice angles of two adjacent lattice regions 310 are different, or the lattice angles of adjacent lattice regions 310 and the overlapping region 310c are different, so that each region of the decorative member 10 reflects light alternately at different viewing angles, and the decorative member 10 presents a sense of layering and space, thereby providing the decorative member 10 with a richer and more diverse shading effect.
[0028] In some embodiments, the grating height H of the overlap region 310c may be equal to or greater than the grating height H of the grating region 310, and / or the grating width D of the overlap region 310c may be equal to or greater than the grating width D of the grating region 310. The grating height H is the height of the grating structure 312, and the grating width D is the width of the grating structure 312. For example, the grating height H of the overlap region 310c may be equal to or greater than the grating height H of the first grating region 310a or the second grating region 310b. In another example, the grating width D of the overlap region 310c may be equal to or greater than the grating width D of the first grating region 310a or the second grating region 310b. In another example, the grating height H and grating width D of the overlap region 310c may be equal to or greater than the grating height H and grating width D of the first grating region 310a or the second grating region 310b, respectively. In this way, the overlapping region 310c has a more pronounced shadow effect relative to the first lattice region 310a or the second lattice region 310b, and the decorative member 10 has a more distinct spatial hierarchy.
[0029] In some embodiments, each lattice region 310 in each lattice pattern 300 overlaps with at least one lattice region 310 in at least one of the other lattice patterns 300, i.e., all lattice regions 310 in the lattice layer 200 overlap with other lattice regions 310, thereby providing a more uniform distribution of the overall shading effect of the decorative member 10 and a clearer spatial hierarchy. In some embodiments, at least some of the lattice regions 310 in the lattice layer 200 are spaced apart from the other lattice regions 310.
[0030] In some embodiments, substrate 100 includes textured surface 101 disposed facing lattice layer 200, and lattice layer 200 is formed on textured surface 101, with lattice region 310 and overlap region 310c completely covering textured surface 101, i.e., any point on textured surface 101 is located in lattice region 310 or overlap region 310c, thereby providing decorative member 10 with a more distinct shadow effect. In some embodiments, textured surface 101 may be partially located outside lattice region 310 or overlap region 310c.
[0031] In some embodiments, the shapes of the multiple lattice regions 310 in each lattice pattern 300 are similar, and the shapes of the multiple lattice regions 310 in different lattice patterns 300 are similar. Similar shapes mean that the lattice regions 310 have the same number of sides. The lengths of the sides and the interior angles of the similar shapes may be different. For example, as shown in FIG. 4 , in the Nth lattice pattern 300, the multiple lattice regions 310 have similar shapes, i.e., all of the multiple lattice regions 310 are triangles, but the lengths of the sides and the interior angles of the different lattice regions 310 may be different. The shapes of the lattice regions 310 may be triangles, rectangles, pentagons, regular polygons, irregular polygons, circles, ellipses, or other special shapes. See FIG. 9 . In some embodiments, the shapes of the lattice regions 310 may also be irregular. For example, some sides of the lattice regions 310 are straight lines and some sides are arcs.
[0032] In some embodiments, the shapes of the multiple grid regions 300 in each grid pattern 300 are similar, and the shapes of the multiple grid regions 310 in at least one grid pattern 300 and the shapes of the multiple grid regions 310 in the other grid patterns 300 are dissimilar. Dissimilar shapes mean that the numbers of sides of the grid regions 310 are different. For example, triangles and rectangles are dissimilar shapes. For example, the shapes of the multiple grid regions 310 in one portion of the M grid patterns 300 may be triangles, and the shapes of the multiple grid regions 310 in another portion of the grid patterns 300 may be rectangles.
[0033] In some embodiments, the shape of at least one grid region 310 and the shapes of other grid regions 310 in at least one grid pattern 300 are dissimilar figures. For example, the shapes of the grid regions 310 in one grid pattern 300 of the M grid patterns 300 may include a triangle and a rectangle.
[0034] See FIG. 10 . In some embodiments, the lattice layer 200 further includes a plurality of second texture regions 220 dispersed on the substrate 100. The plurality of second texture regions 220 are disposed adjacent to the first texture regions 210 and / or the plurality of second texture regions 220 are embedded in the first texture regions 210. The plurality of second texture regions 220 may be regularly or randomly distributed on the substrate 100. For example, the plurality of second texture regions 220 may be distributed in an array on the substrate 100. In some embodiments, at least two of the plurality of second texture regions 220 have different heights, which provides the decorative member 10 with a shading effect due to a matte texture. For example, the second texture regions 220 may be configured as protrusions protruding from the substrate 100 or as grooves formed in the substrate 100. In some embodiments, the area of the second texture region 220 is smaller than the area of the lattice region 310. The lattice structures 312 are disposed in the second texture region 220, and the lattice angles of the plurality of second texture regions 220 are randomly set, thereby providing the decorative member 10 with a shading effect of a shiny sand texture. In some embodiments, the heights of at least two of the plurality of second texture regions 220 are different, and the area of the second texture region 220 is smaller than the area of the lattice region 310, thereby providing the decorative member 10 with a shading effect of a matte texture and a shiny sand texture. For example, the second texture region 220 may be configured as a protrusion protruding from the base 100. The area of the end surface of the protrusion away from the base 100 is smaller than the area of the lattice region 310, and the lattice structures 312 are disposed on the end surface of the protrusion away from the base 100. The lattice angles of the plurality of second texture regions 220 are randomly set.
[0035] The substrate 100 may be configured as a plate-like structure, a curved structure, or other regular or irregular structures. For example, in this embodiment, the substrate 100 is configured as a plate-like structure. The substrate 100 includes a flat and continuous surface. The flat and continuous surface may be planar and / or curved. The lattice layer 200 is formed on the flat and continuous surface of the substrate 100, which facilitates processing and shaping of the lattice layer 200. Examples of the substrate 100 include, but are not limited to, polycarbonate (PC film) sheets, polyethylene terephthalate (PET) sheets, glass sheets, composite sheets, ceramic sheets, metal sheets, etc. Composite sheets include, but are not limited to, PC composite sheets, glass fiber composite sheets, or other polymer composite sheets. An example of a PC composite sheet is a polycarbonate / polymethyl methacrylate (PC / PMMA) composite sheet. The substrate 100 may be made of a transparent material having a predetermined refractive index. In some embodiments, the substrate 100 may also be made of an opaque material, which is not particularly limited in this application.
[0036] Please refer to Figure 11. Figure 11 is a flowchart of a method for making a decorative member 10 according to some embodiments of the present application. The method for making a decorative member 10 includes the following.
[0037] Step 101: Obtain a substrate.
[0038] Step 102: Overlap and synthesize the M grid patterns based on a preset relationship to obtain a grid layer.
[0039] Each of the grid patterns 300 includes a plurality of grid regions 310 arranged at intervals. The grid angles of the grid regions 310 on at least two of the M grid patterns 300 are different.
[0040] At least one lattice region 310 in the (N+1)th lattice pattern 300 is overlapped with at least one lattice region 310 in the Nth lattice pattern, and the lattice angle a of the lattice region 310 in the Nth lattice pattern 300, the lattice angle b of the lattice region 310 in the (N+1)th lattice pattern 300, and the lattice angle c of the overlapping region 310c between the lattice region 310 in the (N+1)th lattice pattern 300 and the lattice region 310 in the Nth lattice pattern 300 satisfy a predetermined relationship: c = X × a + Y × b. N and M are integers, and 1≦N≦M−2. X is represented as a first weight, and Y is represented as a second weight. When the grid angle a of the grid region 310 in the Nth grid pattern 300 is different from the grid angle b of the grid region 310 in the (N+1)th grid pattern 300, the first weight and the second weight satisfy 0.8≦X+Y≦1. In some embodiments, when the grid angle a of the grid region 310 in the Nth grid pattern 300 is different from the grid angle b of the grid region 310 in the (N+1)th grid pattern 300, the first weight and the second weight satisfy 0.8≦X+Y≦1.
[0041] Step 103: Form a lattice layer on the substrate to obtain a decorative member.
[0042] In some embodiments, the second weight is equal to or greater than the first weight in at least a portion of the first texture region 210. For example, the first weight may be 0.3 and the second weight may be 0.7, which causes the lattice angle c of the overlap region 310c in the lattice layer 200 to be closer to the lattice angle b of the second lattice region 310b, making the texture effect of the lattice pattern 300 in the lattice layer 200 farther from the substrate 100 more obvious and creating a gradual depth effect. Therefore, the spatial hierarchy of the decorative member 10 becomes more obvious. In some embodiments, both the first weight and the second weight may be 0.5, which causes the shading effect of the decorative member 10 to be more uniform and improves the spatial hierarchy of the decorative member 10.
[0043] One embodiment of the present application further provides a housing. The housing includes a base plate and the decorative member 10 of any one of the above-described embodiments. The decorative member 10 is disposed on at least a portion of the surface of the base plate. For example, the decorative member 10 is disposed on the inner surface of the housing. In another example, the housing may include a patterned area and a decorative area, and the decorative member 10 is disposed in the decorative area. The shape of the patterned area may be one of a circle, a triangle, a rectangle, a trapezoid, a polygon, or a combination of multiple patterns forming a special figure or pattern. The housing has the same beneficial effects as the decorative member 10 of the above-described embodiments, and the details will not be described again here. The housing may be a mobile phone housing, a tablet computer housing, a notebook computer housing, a watch housing, a water cup housing, a remote control housing, a box housing, an outer cover protective shell of an electronic device, etc. The housing may be a plastic housing, a glass housing, a metal housing, etc. In some embodiments, the grating layer 200 may be transferred directly to the base plate via a mold, i.e., the base plate of the housing serves as the substrate 100 for the grating layer 200.
[0044] As shown in FIG. 12 , an embodiment of the present application further provides an electronic device 1000. The electronic device may be, for example, a tablet computer, a mobile phone, a wristwatch, an e-book reader, a remote control, a personal computer (PC), a notebook computer, a digital assistant (PDA), an in-car device, an internet-enabled television, a wearable device, or a television.
