Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority to a Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on March 17, 2022, bearing application number 202220594546.4 and application title "Glitter Module and Electronic Product", the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of light reflecting patterns, and more particularly to glitter modules and electronic products. [Background technology]

[0003] Currently, the glitter sand texture effect is often achieved by etching a substrate such as glass with an anti-glare agent or by inkjet printing on the substrate surface to form a crystal structure of multiple irregular polyhedral pyramids (as shown in FIG. 1). When light is irradiated, the different faces of the polyhedral pyramids reflect and scatter the light to form a glittery glitter sand effect. However, the polyhedral structure thus formed is completely random, and the glitter effect lacks gradation and flow effects and looks monotonous. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] In order to clarify the technical problems, technical means and advantageous effects that the present application aims to solve, the present application will be described in more detail below with reference to the drawings and examples. It should be understood that the specific examples described in this specification are merely for the purpose of interpreting the present application, and do not limit the present application.

[0019] In this description, unless otherwise stated, "plurality" means two or more.

[0020] In the description of this application, the term "extension direction" refers to the orientation of the strip-shaped groove and is merely intended to express the orientation of the strip-shaped groove; for example, in the case of a strip-shaped object, its longitudinal direction can usually be defined as its extension direction.

[0021] In the description of the present application, the term "specific direction" is an artificially defined direction. When designing a pattern, the "specific direction" of the primary region is first determined. Since the included angle between the extension directions of the strip-shaped grooves of multiple secondary regions in the same primary region and the specific direction of the corresponding primary region is -20° to 20°, the orientation range of the "extension direction" of the strip-shaped groove can be determined based on the "specific direction" of the primary region, and the "specific direction" of the primary region can be inversely estimated based on the "extension direction" of the strip-shaped groove in each secondary region. For example, the extension directions of the strip-shaped grooves of multiple secondary regions in the same primary region change within a certain included angle range, and two secondary regions whose "extension directions" of the strip-shaped grooves form the largest included angle are found, and the angle bisector of the included angle is taken as the "specific direction" of the primary region.

[0022] In the present description, the term "predetermined direction" is an artificially defined direction, which is the basis for determining the "specific direction" of the primary region; specifically, the gradation direction of the required reflection pattern is the "predetermined direction", i.e., a light-dark gradation appears in the reflection pattern along the "predetermined direction".

[0023] In the description of the present application, the term “gradual gradient change relationship” refers to the change relationship of the angle between the specific direction of the multiple primary regions and the predetermined direction, and refers to that, among the multiple primary regions distributed along the predetermined direction, the included angle between the specific direction of the primary regions and the predetermined direction gradually becomes larger or smaller. For example, along the predetermined direction, the included angle between the specific direction of the primary regions and the predetermined direction is 0°, 20°, 40°, 60°, etc., respectively, and gradually increases.

[0024] As shown in FIGS. 2 to 6 , a glitter module according to an embodiment of the present application includes a substrate 1 and a reflective pattern 2 located on a surface of the substrate 1, the reflective pattern 2 includes a plurality of primary regions 21, the primary region 21 includes a plurality of secondary regions 211, A plurality of belt-shaped grooves 2111 are provided in the secondary region 211, the plurality of belt-shaped grooves 2111 in the same secondary region 211 are provided in parallel, and the plurality of belt-shaped grooves 2111 in the same secondary region 211 extend in the same direction; Each primary region 21 has a specific direction, and an included angle between the extension direction of the band-shaped grooves 2111 of the multiple secondary regions 211 in the same primary region 21 and the specific direction of the corresponding primary region 21 is -20° to 20°; Along a given direction of the reflection pattern 2, the angles between the specific directions of the plurality of primary regions 21 and the given direction are in a step-wise gradient change relationship.

[0025] As shown in Figures 2 and 3, the glitter module is provided with a plurality of primary regions 21, and the primary region 21 is subdivided into a plurality of secondary regions 211. A raster image is formed in the secondary region 211 by providing a plurality of strip-shaped grooves 2111. When the raster image is at a different angle with respect to the incident light and the viewer's field of vision, it can show different reflection effects. The reflection effect of the raster image is related to the extension direction of the strip-shaped grooves 2111. By controlling the included angle between the extension direction of the strip-shaped grooves 2111 in different secondary regions 211 and the specific direction of the primary region 21 and changing it between -20° and 20°, there is a difference in the extension direction of the strip-shaped grooves 2111 between the plurality of secondary regions 211 in the single primary region 21. As a result, there is a difference in the reflection effect of the light beam by the plurality of secondary regions 211 in the single primary region 21. When observed from the same field of vision, a glitter effect is obtained.

[0026] In the present application, the included angle between a specific direction of the multiple primary regions 21 and a predetermined direction of the reflective pattern 2 is controlled to gradually change the gradient, so that a gradation relationship exists in the raster reflective characteristics of the multiple primary regions 21, and when the reflective pattern 2 is observed from the same field of view, the characteristics of light and dark gradation can be seen; when the glitter module is rotated or the observation field of view is changed, the gradation reflective effect of the reflective pattern 2 has continuous fluidity, and a fluid glitter effect is realized, thereby enriching the visual effect of the appearance.

[0027] Specifically, as shown in FIGS. 3 to 6, in a specific embodiment, the direction from the lower left to the upper right in the figure is set as the predetermined direction of the reflection pattern 2, and primary region 21c, primary region 21b, and primary region 21a are selected along the predetermined direction of the reflection pattern 2. As can be seen from FIGS. 4 to 6, there are a plurality of secondary regions 211a in primary region 21a, and the specific direction of primary region 21a is known from the extension direction of the strip-shaped grooves of the plurality of secondary regions 211a. b, a specific direction of the primary region 21b can be determined from the extension direction of the strip-shaped grooves of the multiple secondary regions 211b, and the primary region 21c has multiple secondary regions 211c, a specific direction of the primary region 21c can be determined from the extension direction of the strip-shaped grooves of the multiple secondary regions 211c, and the included angle between the specific direction of the primary region 21c, the specific direction of the primary region 21b and the specific direction of the primary region 21a and the specific direction of the reflection pattern 2 gradually increases along the specific direction of the reflection pattern 2.

[0028] In one embodiment, the angle between the extension direction of the band-shaped grooves 2111 of the multiple secondary regions 211 in the same primary region 21 and the specific direction of the corresponding primary region 21 is -15° to 15°.

[0029] In one embodiment, the angle between the extension direction of the band-shaped grooves 2111 of the multiple secondary regions 211 in the same primary region 21 and the specific direction of the corresponding primary region 21 is -10° to 10°.

[0030] When the included angle between the extension direction of the band-shaped groove 2111 of the secondary region 211 and the specific direction of the corresponding primary region 21 is within the above range, it is not only possible to ensure that the glitter effect can be exhibited in a single primary region 21, but also to avoid the problem that the range of the included angle is too wide, making the difference in the reflective effects of different primary regions 21 unclear, thereby affecting the glitter gradation effect and reflective fluidity.

[0031] In some embodiments, along a given direction of the reflection pattern 2, the included angle between a particular direction of the plurality of primary regions 21 and the given direction varies with a gradient between 90° and −90°.

[0032] 7 is a simplified principle diagram, showing a single secondary region 211 and a corresponding primary region 21, and the extension direction of the strip-shaped groove 2111 of the secondary region 211 indicates the specific direction of the primary region 21. It can be seen that at the leading end of the specific direction of the reflection pattern 2, the included angle between the specific direction of the primary region 21 and the specific direction is 90°, when reaching the middle position of the specific direction, the included angle between the specific direction of the primary region 21 and the specific direction gradually decreases to 0°, and when reaching the end of the specific direction, the included angle between the specific direction of the primary region 21 and the specific direction gradually decreases to -90°. At this time, the reflection effect of the corresponding glitter module is as shown in FIG. 3, and the reflection pattern 2 shows a dark to bright gradation effect from the lower left to the upper right, and when the glitter module is rotated, the position of the gradation effect moves.

[0033] It should be noted that the above is merely one embodiment of the present application. In other embodiments, the angle between the specific direction of the plurality of primary regions 21 and the predetermined direction along the predetermined direction of the reflection pattern 2 may vary with a gradient in another angle range, or the angle between the specific direction of the plurality of primary regions 21 and the predetermined direction along the predetermined direction of the reflection pattern 2 may vary with a gradient in the range of 90° to −90° and be repeated periodically, thereby realizing a multi-stage gradation effect in the predetermined direction of the reflection pattern 2.

[0034] In one embodiment, the primary region 21 is an irregular polygon.

[0035] In other embodiments, the primary area 21 may be a regular polygon, such as a square, a triangle, or the like.

[0036] In one embodiment, to ensure continuity of the gradation effect, the primary regions 21 are interlocked and distributed like a jigsaw puzzle.

[0037] As shown in FIG. 4, in one embodiment, the secondary region 211 is an irregular polygon.

[0038] As shown in FIG. 8, in one embodiment, the secondary region 211 is triangular.

[0039] In other embodiments, the secondary regions 211 may be configured in other regular or irregular shapes.

[0040] As shown in FIG. 4, in one embodiment, in the same primary region 21, a plurality of secondary regions 211 are arranged in a jointed manner like a jigsaw puzzle.

[0041] By setting a plurality of the secondary regions 211 so as to be jointly distributed like a jigsaw puzzle, it is possible to improve the light and dark gradation effect and the continuity of the flow of light and shadow at different angles.

[0042] As shown in FIG. 8, in one embodiment, in the same primary region 21, the secondary regions 211 are distributed at dot matrix intervals.

[0043] By setting multiple secondary regions 211 to be distributed at dot matrix intervals, gaps are generated between adjacent secondary regions 211, making the glitter effect more obvious, but relatively weakening the gradation effect and flow continuous effect.

[0044] In some embodiments, the spacing between the multiple groove strips 2111 in the same secondary region 211 is 0 μm to 50 μm, the width of the groove strips 2111 is 10 μm to 50 μm, and the depth of the groove strips 2111 is 0.5 μm to 10 μm.

[0045] In some embodiments, the secondary region 211 is provided with a plurality of band-shaped protrusions 2112, the plurality of band-shaped protrusions 2112 are arranged in parallel, a single band-shaped groove 2111 is formed between two adjacent band-shaped protrusions 2112, the width of the band-shaped protrusions 2112 is 10 μm to 50 μm, the height of the band-shaped protrusions 2112 is 0.5 μm to 10 μm, and the distance between the two adjacent band-shaped protrusions 2112 is 0 μm to 50 μm.

[0046] In different embodiments, the cross-section and spacing of the strips 2112 in the secondary region 211 may be designed differently.

[0047] For example, as shown in FIG. 9, in one embodiment, the cross section of the band-shaped protrusions 2112 is an equilateral triangle, and the multiple band-shaped protrusions 2112 are provided at intervals.

[0048] As shown in FIG. 10, in one embodiment, the cross section of the band-shaped protrusions 2112 is a right-angled triangle, and the band-shaped protrusions 2112 are spaced apart.

[0049] As shown in FIG. 11, in one embodiment, the cross section of the band-shaped protrusion 2112 is a right-angled triangle, and multiple band-shaped protrusions 2112 are arranged adjacent to each other, and of two adjacent band-shaped protrusions 2112, the band-shaped groove 2111 is formed between the right-angled surface of one band-shaped protrusion 2112 and the inclined surface of the other band-shaped protrusion 2112.

[0050] As shown in FIG. 12, in one embodiment, the cross section of the band-shaped protrusions 2112 is semicircular, and the band-shaped protrusions 2112 are spaced apart.

[0051] As shown in FIG. 13, in one embodiment, the cross section of the band-shaped protrusion 2112 is semicircular, and multiple band-shaped protrusions 2112 are arranged adjacent to each other, and the band-shaped groove 2111 is formed between the side surfaces of two adjacent band-shaped protrusions 2112.

[0052] In some embodiments, the substrate 1 is selected from a plate-like structure, a curved structure, or an irregular shape.

[0053] In one embodiment, the substrate 1 has a flat surface, and the reflection pattern 2 is formed on the flat surface. The flat surface may be a flat surface, a curved surface, or a combination of a flat surface and a curved surface. Providing a flat surface is more advantageous for processing and forming the reflection pattern 2 than a curved surface.

[0054] In one embodiment, the substrate 1 is a completely flat straight plate structure or a curved 3D cover plate structure with slight bends on both sides.

[0055] In some embodiments, the substrate 1 is selected from a glass substrate or a plastic sheet material.

[0056] When the above-mentioned substrate 1 is selected from a glass substrate, a photoresist can be applied to the glass surface, exposed, developed and etched to form a mask having a reflective pattern 2, and then wet or dry etching can be carried out. Due to the protective effect of the photoresist on the glass, the thicker photoresist portion requires a longer etching time, while the thinner photoresist portion requires a shorter etching time. The underlying glass layer is exposed before the thicker photoresist portion. With a reasonable etching time, the texture of the reflective pattern 2 can be completely copied onto the glass, and then the coating, spraying or printing process can be carried out to make a finished product, forming the gradient glitter glass.

[0057] If the substrate 1 is selected from a plastic sheet material, the data of the reflective pattern 2 is transmitted to a computer, and the photolithography and exposure are carried out on a glass plate on which the photoresist is uniformly distributed, and then the photolithography and exposure are carried out, followed by development, drying and plasma cleaning, followed by UV (ultraviolet) transfer to transfer the texture to a PC (polycarbonate) sheet material, and then the reflective pattern 2 is formed on the plastic sheet material by UV transfer. The plastic sheet material may be selected from a film material or a plate-shaped material. If the plastic sheet material is selected from a film material, the plastic sheet material can be laminated on the glass or other substrate 1 after carrying out processes such as coating, printing and lamination, to form a decorative film material. If the plastic sheet material is selected from a plate-shaped material, hot pressing can be carried out to form a finished textured plastic sheet material.

[0058] An electronic product according to another embodiment of the present application includes the glitter module described above.

[0059] The glitter module is used as a housing or part of the housing of the electronic product. Since the electronic product uses the glitter module described above, it can show a light and dark gradation effect and a fluid glitter effect on its surface, and has excellent aesthetics. In addition, since the pattern is directly formed by the substrate 1, the problem of the pattern falling off during use can be effectively avoided.

[0060] In some embodiments, the electronic product is selected from a mobile phone or a tablet.

[0061] The above description is only a preferred embodiment of the present application, and does not limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application should be included within the protection scope of the present application.
