[0020] DETAILED DESCRIPTION OF THE INVENTION The following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure.

[0021] In order to make the above-mentioned objects, features, and advantages of the present disclosure more clearly understood, the present disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless there is a contradiction, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0022] The following clearly and completely describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, not all of them. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present application without any inventive efforts are included in the protection scope of the present application.

[0023] It should be understood that the terms used in the specification, claims, and accompanying drawings of this application are intended merely to describe particular embodiments and are not intended to limit the present application. Terms such as "first," "second," and the like in the specification, claims, and accompanying drawings of this application are used to distinguish between different objects and are not used to describe a particular order. The singular forms "a" and "an" and "the" are intended to include the plural unless the context clearly dictates otherwise. The terms "comprise" and "include" and variations thereof are intended to include a non-exclusive inclusion. In addition, this application may be embodied in multiple different forms and is not limited to the embodiment described in this embodiment. The following specific embodiments are provided to facilitate a clearer and more thorough understanding of the content disclosed herein. Directional terms such as top, bottom, left, and right are used only with respect to the positions of structures shown in the corresponding accompanying drawings.

[0024] In the description of this application, unless expressly specified or defined otherwise, the terms "mount," "interconnect," "connect," and "disposed on" should be understood broadly. For example, connection can be understood as fixedly connected, detachably connected, integrally connected, mechanically connected, directly connected, or indirectly connected using an intermediate medium or interconnecting two elements. Those skilled in the art can understand the specific meaning of the foregoing terms in this application based on the specific context.

[0025] First, the basic concepts used in the embodiments of the present application will be briefly described below.

[0026] In the description of the present application, the term "predetermined direction" refers to the extension direction of the stripes. For example, in the case of a strip-shaped object, the length direction of the strip-shaped object is generally the extension direction of the strip-shaped object. For example, in the embodiment of the present application, the stripes are a grid line pattern when viewed from above.

[0027] In the present description, the term "gradient varying" is used to indicate that the range of random variation in the size of multiple texture regions or the height of second texture structures increases or decreases gradually along a specified direction, the specified direction being from the first surface to the second surface.

[0028] Please refer to Figures 1 and 2. Figure 1 is a top view of a decorative member 100 according to a first embodiment of the present application. Figure 2 is a partial cross-sectional view of the decorative member 100 of Figure 1 taken along line AA. The decorative member 100 includes a base layer 10 and an optical texture layer 30 disposed on the base layer 10. When light passes through the optical texture layer 30, the light is reflected, refracted, etc., to form a decorative effect of bright rays of light and shadow.

[0029] In some embodiments, the base layer 10 and the optical texture layer 30 may be a single structure. The base layer 10 and the optical texture layer 30 may be formed by pressing a photocurable adhesive layer, a thermosetting adhesive layer, a thermoplastic film, or the like, into a mold and then curing the pressed layer. In some embodiments, the base layer 10 and the optical texture layer 30 may alternatively be separate structures. The base layer 10 may be made of any transparent material, and the optical texture layer 30 is a photocurable adhesive layer, a thermosetting adhesive layer, or a thermoplastic film. In one embodiment, a film is first formed on the base layer 10, and then, before the film is cured, the film is pressed into a corresponding mold to form the optical texture layer 30.

[0030] The base layer 10 may be configured as a plate-like structure, a curved structure, another regular or irregular shaped structure, etc. For example, in this embodiment, the base layer 10 is configured as a plate-like structure. The base layer 10 includes a flat, uninterrupted surface. The flat, uninterrupted surface may be planar and / or curved. The optical texture layer 30 is formed on the flat, uninterrupted surface of the base layer 10, thereby facilitating processing and shaping of the optical texture layer 30. The base layer 10 may be configured as, but is not limited to, a polycarbonate (polycarbonate, PC film) film, a polyethylene terephthalate (polyethylene terephthalate, PET) film, a glass substrate, or a composite plate such as polycarbonate + polymethyl methacrylate (polycarbonate + polymethyl methacrylate, PC / PMMA).

[0031] For example, in this embodiment, the optical texture layer 30 includes a plurality of stripes 301 extending in a predetermined direction. At least a portion of the stripes 301 includes a first texture structure 31 disposed on the base layer 10 and a plurality of second texture structures 32, some of which belong to the first texture structure 31 and are disposed on a surface facing away from the base layer 10. The heights of the plurality of second texture structures 32 vary randomly. In some embodiments, the maximum height of each second texture structure 32 in the plurality of second texture structures 32 ranges from 0.05 μm to 7 μm.

[0032] Optionally, in this embodiment, all of the stripes 301 include the first texture structure 31 and the second texture structure 32, so that the overall structure of the decorative member 100 presents a matte effect.

[0033] According to the decorative member 100 provided herein, the plurality of second texture structures 32 are disposed on the surface of the first texture structure 31 facing away from the base layer 10, the heights of the plurality of second texture structures 32 vary randomly, the first texture structure 31 has a decorative effect of bright rays of light and shadow, and the second texture structure 32 has a matte effect, such that the decorative member 100 achieves the effect of light and shadow through a matte texture, and the overall effect of the decorative member 100 is richer, more diverse, and more aesthetic. In addition, since the second texture structure 32 is disposed directly on the first texture structure 31, the manufacturing process is simple, the cost is low, and the product yield is high.

[0034] It should be noted that the purpose of Figure 2 is simply to roughly explain the arrangement manner between the base layer 10 and the optical texture layer 30, and does not impose specific limitations on the connection locations of each element, the connection relationships, the specific structures, etc. Figure 2 is merely an example of the decorative member 100 and does not constitute limitations on the decorative member 100. The decorative member 100 may include more or fewer components than those shown in Figure 2, or may combine some components, or may include different components. For example, the decorative member 100 may further include functional layers such as a coloring layer and a reflective layer.

[0035] The shape of the stripes 301 (i.e., the extension path of the stripes 301) may be configured as one or a combination of two or more of, but is not limited to, a straight line, a curved line, and a dashed line. The curved line may be a regular curved line or an irregular curved line. For example, the curved line may be, but is not limited to, a circular arc, a parabola, a sine curve, a cosine curve, etc. The extension directions of the multiple stripes 301 may be the same or different. For example, as shown in FIG. 1 , in this embodiment, the multiple stripes 301 extend continuously in a predetermined direction, so that the bright rays of light and shadow in the optical texture layer 30 have a stronger overall sense. The extension directions of the multiple stripes 301 are configured to have the same shape, i.e., a circular arc shape. Different stripes 301 have the same radius of curvature. In some embodiments, different stripes 301 have different radii of curvature. Optionally, the multiple stripes 301 may be arranged radially or concentrically on the base layer 10. It should be noted that the stripes 301 are band-shaped protrusions disposed on the base layer 10. In this embodiment, two adjacent band-shaped protrusions may be spaced apart from each other. In some embodiments, two adjacent band-shaped protrusions are disposed adjacent to each other. A band-shaped recess 302 is formed between two adjacent stripes 301. As a result, the decorative member 100 can exhibit a light and shadow effect in which light and shadow alternate with changes in the height of the texture, providing a good decorative effect.

[0036] In some embodiments, please refer to FIG. 3. FIG. 3 is a top view of a decorative member 100A according to a second embodiment of the present application. As shown in FIG. 3, the plurality of stripes 301 includes a plurality of first stripes 310 and a plurality of second stripes 320. The extension direction of the first stripes 310 intersects the extension direction of the second stripes 320. In some embodiments, the extension path of the first stripes 310 intersects the extension path of the second stripes 320. In some embodiments, the extension path of at least some of the plurality of first stripes 310 intersects the extension path of some of the plurality of second stripes 320. In other embodiments, the extension path of some of the plurality of second stripes 320 does not intersect with the plurality of first stripes 310. The plurality of second stripes 320 defines at least a portion of the first stripes 310. In one embodiment, the orthogonal projection of the plurality of second stripes 320 on the base layer 10 surrounds the orthogonal projection of the plurality of first stripes 310 on the base layer 10. The first regions 303 corresponding to the plurality of first stripes 310 are joined end-to-end with the second regions 304 corresponding to the plurality of second stripes 320. That is, the first regions 303 and the second regions 304 are joined end-to-end and distributed like a jigsaw puzzle. As a result, the user can see different images from different angles, and the gradual light and shadow effects of the first regions 303 and the second regions 304 and the continuity of the flowing light and shadow at various angles can be ensured, which has a better decorative effect. In one embodiment, the plurality of first stripes 303 and the plurality of second stripes 320 together cover the entire base layer 10.

[0037] It should be noted that the cross section of the first texture structure 31 is a cross section of the first texture structure 31 in the width direction of the first texture structure 31, and the width direction of the first texture structure 31 is the normal direction of the extension path of the stripes 301, i.e., the direction perpendicular to the tangential direction of the stripes 301. For clearer explanation, the X-axis direction is defined as the width direction of the optical texture layer 30, and the Y-axis direction is defined as the height direction of the optical texture layer 30. For example, the direction of the arrow in the Y-axis direction is upward, and the direction opposite to the direction of the arrow in the Y-axis direction is downward.

[0038] The first texture structure 31 may be one or a combination of, but not limited to, a prism, a straight cylindrical mirror, a curved cylindrical mirror, a CD pattern, a lined pattern, or a short line, allowing various optical textures to be formed and various visual effects to be presented. The cross-sectional shape of the first texture structure 31 may be, but is not limited to, an arc, a triangle, a square, a trapezoid, a regular polygon, or an irregular polygon. The triangle may be, but is not limited to, a right triangle, an equilateral triangle, or an isosceles triangle. For example, in this embodiment, the cross-sectional shape of the first texture structure 31 is an arc, such as a semicircle. The height of the first texture structure 31 in the height direction of the optical texture layer 30 gradually decreases from the center to both ends. The heights of both ends of the first texture structure 31 are zero or close to zero.

[0039] The plurality of second texture structures 32 are configured as an undulating structure in the height direction of the first texture structure 31. The undulating structure includes a plurality of protrusions protruding outward relative to the first texture structure 31 and / or a plurality of recesses recessed inward relative to the first texture structure 31. The heights of the plurality of protrusions vary randomly, and / or the heights of the plurality of recesses vary randomly. The undulating structure can diffusely reflect light, thereby allowing the decorative member 100 to exhibit a matte optical effect. At least one parameter of the length, width, or height of the plurality of second texture structures 32 varies, thereby allowing the second texture structures 32 to achieve different diffuse reflection effects, thereby improving the three-dimensional effect and aesthetics of the decorative member 100. Specifically, in this embodiment, the first texture structure 31 includes a first surface 311 in contact with the base layer 10 and a second surface 312 connected to the first surface 311 and protruding outward relative to the first surface 311. The relief structure is formed on the second surface 312. The second texture structure 32 is arranged in a checkerboard pattern in the extension direction of the first texture structure 31, that is, the second texture structure 32 is a plurality of checkerboard blocks with randomly varying heights disposed on the second surface 312 of the first texture structure 31.

[0040] The plurality of second texture structures 32 are arranged in a dispersed manner on the first texture structure 31. The plurality of second texture structures 32 may be arranged in a lattice pattern or in a non-lattice pattern. It should be noted that the term "dispersed" means that the center points of the orthogonal projections of the second texture structures 32 in the height direction of the first texture structure 31 are distributed in a dispersed manner.

[0041] In some embodiments, two adjacent stripes 301 are spaced apart from each other. A plurality of second texture structures 32 are further disposed between the two adjacent stripes 301, so that the decorative member 100 achieves a matte effect as a whole. Optionally, a plurality of second texture structures 32 are further disposed in a dispersed manner in the area between the two adjacent stripes 301 corresponding to the optical texture layer 30. In some other embodiments, the spacing between the two adjacent stripes 301 is small, so that the second texture structures 32 may not be disposed between the two adjacent stripes 301. In some other embodiments, the two adjacent stripes 301 are disposed adjacent to each other. For example, in this embodiment, the optical texture layer 30 further includes a third texture structure 33 connected between two adjacent first texture structures 31. The second texture structure 32 is disposed on the surface belonging to the third texture structure 33 and facing away from the base layer 10, thereby further enhancing the light and shadow effect due to the matte texture of the decorative member 100. The third texture structure 33 has a linear panel structure. The height of the third texture structure 33 is smaller than the height of the first texture structure 31. In some other embodiments, the optical texture layer 30 has only the second texture structure 32, but not the third texture structure 33, between two adjacent first texture structures 31. In some other embodiments, the optical texture layer 30 may not include the second texture structure 32 or the third texture structure 33 between two adjacent first texture structures 31.

[0042] It can be understood that the height variation range of the second texture structure 32 also affects the light and shadow of the decorative member 100. The height variation range of the second texture structure 32 is based on the maximum height value of the first texture structure 31. The smaller the height variation range of the second texture structure 32, the smaller the impact of the first texture structure 31 on the light and shadow, indicating a weaker matte texture. The larger the height variation range of the second texture structure 32, the greater the impact of the first texture structure 31 on the light and shadow, indicating a stronger matte texture, and even the matte characteristics are visible to the naked eye. Optionally, in some embodiments, the ratio of the height of the second texture structure 32 to the maximum height of the first texture structure 31 ranges from 5% to 25%, that is, the height of the second texture structure 32 accounts for 5% to 25% of the maximum height of the first texture structure 31, so that the second texture structure 32 presents a concave-convex texture on the first texture structure 31, and the side of the optical texture layer 30 facing away from the base layer 10 is no longer a smooth surface but an undulating surface, which increases the irregular reflection of reflected light in various directions and achieves a matte effect, thereby ensuring that the decorative member 100 presents the light and shadow effect of a matte texture. In particular, the first texture structure 31 and the second texture structure 32 are combined to form the composite texture structure 300, which simplifies the manufacturing process of the optical texture layer 30 and achieves low cost and high product yield. The height range of the composite texture structure 300 is hi±hmax×k, where hi represents the height value of the first texture structure 31 in a particular area, hmax represents the maximum height value of the first texture structure 31, and k represents the ratio of the height of the second texture structure 32 to the maximum height of the first texture structure 31.

[0043] For example, if the maximum height value of the first texture structure 31 is 10 μm, the height variation range of the second texture structure 32 is 10% of the maximum height value of the first texture structure 31, and the height value of the first texture structure 31 in a specific region is 5 μm, the height range of the composite texture structure 300 is 5 μm±10 μm×10% (i.e., 4 μm to 6 μm). In other words, the height of the composite texture structure 300 is a random value of 5 μm±10 μm×10%. In this embodiment, the minimum height of the composite texture structure 300 is 0 μm.

[0044] Please refer to Figures 4 and 5. Figure 4 is a top view of the textured layer 30 of the decorative member 100 of Figure 1. Figure 5 is an illustration of the frosted matte effect of the decorative member 100 of Figure 4.

[0045] For example, in this embodiment, the area of ​​the optical texture layer 30 corresponding to the first texture structure 31 is divided into a plurality of texture regions 305 arranged in a checkerboard pattern, and each second texture structure 32 is disposed in the corresponding texture region 305, with the amount of the second texture structure 31 being equal to or less than the amount of the texture region 305. Each second texture structure 32 covers the corresponding texture region 305. In some embodiments, the amount of the second texture structures 32 corresponds one-to-one with the amount of the texture region 305, that is, one second texture structure 32 is disposed in each texture region 305. In some embodiments, at least one texture region 305 may not have a second texture structure 32 disposed therein.

[0046] It can be understood that the smaller the size of the textured region 305, the less the first textured structure 31 affects the light and shadow effect and the weaker the matte texture. The larger the size of the textured region 305, the more the first textured structure 31 affects the light and shadow effect, indicating a stronger matte texture, and even the matte characteristics are visible to the naked eye. The size of the textured region 305 is 0.5 μm × 0.5 μm to 2.5 μm × 2.5 μm, thereby ensuring that the decorative member 100 exhibits the light and shadow effect of the matte texture. The size of the textured region 305 may be, but is not limited to, 0.5 μm × 0.5 μm, 1.0 μm × 1.0 μm, 2.0 μm × 2.0 μm, or 2.5 μm × 2.5 μm. It should be noted that the size of the textured region 305 is used for illustrative purposes only and does not constitute a specific limitation. The size of the texture region 305 needs to be designed based on the actual product design. The sizes of the multiple texture regions 305 may be the same. Alternatively, some texture regions 305 may have the same size, and other texture regions 305 may have different sizes. Alternatively, the sizes of the multiple texture regions 305 are completely different. This is not particularly limited in the present application.

[0047] In this embodiment, the area between two adjacent stripes 301 corresponding to the optical texture layer 30 is also divided into multiple texture areas 305, and the second texture structures 32 are also disposed in at least a part of the texture areas 305, so that the decorative member 100 achieves a more uniform matte effect as a whole. All the texture areas 305 corresponding to the optical texture layer 30 are arranged in a checkerboard pattern, which facilitates processing and improves production efficiency. In some embodiments, only the area of ​​the optical texture layer 30 corresponding to the first texture structures 31 is divided into texture areas 305 for disposing the corresponding second texture structures 32.

[0048] Optionally, in some embodiments, the optical texture layer 30 comprises a first surface 3051 and a second surface 3052 disposed opposite the first surface 3051, and the size of the plurality of textured regions 305 gradually changes from the first surface 3051 to the second surface 3052, and / or the random range of height changes of the second texture structures 32 gradually changes from the first surface 3501 to the second surface 3502. As shown in FIG. 5 , the microscopic characteristics of the decorative member 100 in the present application are measured using a confocal microscope. It is observed that the microscopic characteristics of the decorative member 100 are a matte composite texture, and that the decorative member 100 has a light and shadow effect with a matte flow. Optionally, the overall light and shadow effect and the matte effect of the decorative member 100 gradually change. For example, in this embodiment, the texture of the optical texture layer 30 changes gradually from the first surface 3051 to the second surface 3052, which creates an overall effect of light and shadow changing from light to matte and a weak to strong matte texture from the first surface 3051 to the second surface 3052. In some embodiments, the texture of the optical texture layer 30 may alternatively be designed as a strong contrast mutation effect, where the matte texture grows from nothing and the light and shadow change from light to matte. The light and shadow effect of the first texture structure 31 and the matte effect of the second texture work together to create a diverse and magnificent overall effect for the decorative member 100.

[0049] In some embodiments, the base layer 10 may be, but is not limited to, a glass substrate or a plastic film. When the base layer 10 is a glass substrate, the method for preparing the decorative member 100 includes using software to set texture parameters for the optical texture layer 30 (i.e., transmitting preset texture parameters for the first texture structure 31 and the second texture structure 32 to a computer), coating a photoresist on the surface of the glass substrate based on the preset texture parameters, and exposing, developing, and etching the photoresist to form the decorative member 100 having the uneven first texture structure 31 and the second texture structure 32, where the etching can be wet etching or dry etching. Specifically, the photoresist-coated glass substrate is placed in a chemical solution etching bath. Thicker portions of the photoresist have a longer etching resistance time, while thinner portions of the photoresist have a shorter etching resistance time. The thinner portions of the photoresist are dissolved before the thinner portions of the photoresist, exposing the glass substrate. Therefore, the first texture structure 31 and the second texture structure 32 can be completely etched into the glass substrate by setting an appropriate etching time for the glass substrate with photoresist placed in an etching bath, and then finished using processes such as coating, spraying, or printing to form a glass product with light and shadow effects and frosted matte effects. The glass substrate is used as the base layer 10. In some embodiments, an optical coating may further be performed on the surface of the glass substrate facing away from the optical texture layer 30. One side of the coating layer is sprayed with an ink layer or another decorative layer.

[0050] When the base layer 10 is a plastic film, the method for preparing the decorative member 100 includes using software to set preset texture parameters for the optical texture layer 30 (i.e., transmitting the preset texture parameters for the first texture structure 31 and the second texture structure 32 to a computer), coating a glass substrate with photoresist based on the preset texture parameters, performing lithography exposure, and performing processes such as development, drying, and plasma cleaning to obtain a texture mold. The texture mold is then subjected to a transfer process (e.g., UV transfer) and curing process to obtain a transfer mold, after which the texture is transferred to the base layer 10. For example, the first texture structure 31 and the second texture structure 32 can be formed on a PC film, a PET sheet, or a composite plate such as PC / PMMA by UV transfer, thereby transferring the optical texture layer 30 onto the base layer 10. The plastic film can be, but is not limited to, a film-like material or a plate-like material. When the plastic film is a film-like material, the plastic film may be attached to glass or another substrate using a process such as coating, printing, or laminating, and used as the decorative member 100. For example, in some embodiments, a coating layer may be deposited on the optical texture layer 30, and an ink layer may be printed on one side of the coating layer, and then the decorative film is attached to the glass using a process such as lamination to produce a glass product having the decorative member 100. When the plastic film is a plate-like material, the finished plastic film product having the first texture structure 31 and the second texture structure 32 may be formed by hot press molding.

[0051] See FIG. 6. FIG. 6 is a cross-sectional view of a decorative member 100B according to a third embodiment of the present application. In some embodiments, the decorative member 100B further includes a glitter-sand layer 50. The glitter-sand layer 50 and the optical texture layer 30 are disposed on the base layer 10 with their ends joined. In one embodiment, the orthogonal projections of the optical texture layers 30 on the base layer 10 surround the orthogonal projection of the glitter-sand layer 50 on the base layer 10. Specifically, the base layer 10 is divided into a first region 11 and a second region 12 that is end-to-end joined to the first region 11. The optical texture layer 30 is disposed in the first region 11, and the glitter-sand layer 50 is disposed in the second region 12. The height of the lattice corresponding to the glitter-sand layer 50 varies randomly, allowing the decorative member 100B to reflect visual effects with special shapes or patterns. For example, the shape of the first region 11 may be approximately the shape of a capital letter "D," allowing the decorative member 100B to reflect the visual effect of the letter "D." In some embodiments, the shape of the first region 11 may be one of a circle, a triangle, a rectangle, a trapezoid, or a polygon, or may be a combination of multiple shapes to form a special graph or pattern. The glitter sand layer 50 allows the decorative member 100B to have better color development and richer colors, resulting in a better texture. The glitter sand layer 50 includes multiple glitter sand particles distributed at intervals. The decorative member 100 further has a glitter sand effect that improves its aesthetics. In addition, the glitter sand layer 50 has strong abrasion resistance, scratch resistance, and fingerprint resistance, which can extend its service life. In addition, because the size of the sand particles can be adjusted, the sand particles are not limited to a single size, resulting in a more diverse glitter sand effect.
