Description

Technical Field

[0001] The present application relates to the field of surface treatment, and in particular to a matte anti-glare structure, plate and glass. Background Art

[0002] Glare refers to visual discomfort and reduced visibility of objects due to inappropriate brightness distribution or extreme brightness contrast in space and time. Strong glare can also cause problems such as decreased vision, depression, and irritability. "Anti-glare" means that when light passes through the screen or the surface of an object, a certain degree of diffuse reflection occurs, reducing specular reflection, thereby reducing the intensity of light entering the human eye, thereby reducing or eliminating discomfort.

[0003] At present, the traditional matte anti-glare (AG) structure mostly randomly selects some points on the surface to be processed before product processing, and then removes the selected points during the processing to form different light and dark contrasts on the surface to be processed. The haze of this anti-glare structure mainly depends on the size of the random points and the size of the irregular dark areas formed by adjacent random points. If the random points are not selected evenly, the haze distribution of the surface to be processed will be uneven. In addition, if the surface to be processed is observed from certain specific viewing angles, obvious patchy dark areas will be seen on the surface to be processed, affecting the overall appearance of the surface to be processed. Summary of the invention

[0006] In some embodiments, the widths of the plurality of gaps are the same, the plurality of polygonal protrusions correspond to a plurality of the ratios, and the difference between the maximum and minimum values ​​of the plurality of ratios is within a second threshold, and the ratios corresponding to any two adjacent polygonal protrusions are randomly distributed, so that the substrate has a single matte effect.

[0007] In some embodiments, the widths of the plurality of gaps are the same, and along the extension direction of the substrate, the maximum cross-sectional widths of the plurality of polygonal protrusions are randomly distributed, so that the substrate has a single matte effect; or, the widths of the plurality of gaps are randomly distributed, and along the extension direction of the substrate, the maximum cross-sectional widths of the plurality of polygonal protrusions are randomly distributed, so that the substrate has a single matte effect.

[0008] In some embodiments, the widths of the plurality of gaps are randomly distributed, and along the extension direction of the substrate, the maximum cross-sectional widths of a plurality of the polygonal protrusions are unidirectionally or periodically gradiently changed, so that the substrate has a gradient matte effect;

[0009] In some embodiments, the widths of the plurality of gaps are the same, and along the extension direction of the substrate, the maximum cross-sectional widths of a plurality of the polygonal protrusions are unidirectionally or periodically gradient, so that the substrate has a gradient matte effect.

[0010] In some embodiments, along the extension direction of the substrate, the ratio is unidirectionally or periodically gradually changed, so that the substrate has a gradual matte effect.

[0012] In some embodiments, the cross-sectional shape of the top of each polygonal protrusion is one of a rectangle, a square, an arc, a wave and a sawtooth.

[0013] In a second aspect, an embodiment of the present application further provides a plate material, comprising a plate body and the above-mentioned matte anti-glare structure arranged on the plate body.

[0014] In a third aspect, an embodiment of the present application further provides a glass, comprising a glass body and the above-described frosted anti-glare structure disposed on the glass body.

[0015] Due to the adoption of the above technical solution, the technical effects achieved by this application are:

[0016] The matte anti-glare structure provided by the present application is provided with a plurality of polygonal protrusions on the substrate, and the structure and gap of each polygonal protrusion, as well as the ratio of the cross-sectional width to the maximum gap width are reasonably set. When irradiated by an external light source, the top of each polygonal protrusion on the surface of the substrate can reflect the light to form a bright light area, and the gap formed between each polygonal protrusion can form a dark light area with a brightness lower than the bright light area because the gap received less light.

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0029] Figure 1 is a schematic diagram of a matte anti-glare structure provided by an embodiment of the present application. Figure 1 As shown, the embodiment of the present application provides a matte anti-glare structure, including a substrate 100 and a plurality of polygonal protrusions 110 disposed on the surface of the substrate 100, wherein the structures of any two adjacent polygonal protrusions 110 are different, and there are a plurality of gaps 120 between any two adjacent polygonal protrusions 110, and the ratio of the maximum cross-sectional width of each polygonal protrusion 110 to the maximum gap width adjacent to the polygonal protrusion 110 is within a first threshold. When the substrate 100 is placed on a horizontal plane, the polygonal protrusion 110 is perpendicular to the horizontal plane, and the maximum cross-sectional width (such as Figure 2 ) is the maximum width of the polygonal protrusion 110 in the horizontal direction when the polygonal protrusion 110 is cut along the vertical direction; the maximum gap width (as shown in FIG. Figure 2 (b) refers to the size corresponding to the maximum gap adjacent to the polygonal protrusion 110 when the polygonal protrusion 110 is observed downward from directly above the substrate.

[0030] Furthermore, under the illumination of an external light source, a bright area is formed on the top of each polygonal protrusion 110 , and a dark area is formed in the gap 120 . The bright area and the dark area cooperate with each other so that the base 100 has a matte effect.

[0031] It should be noted that the substrate 100 is mainly used to support a plurality of polygonal protrusions 110 , which may be a metal film, a non-metallic film, a colloid layer, a wood layer, a glass layer, etc. The embodiment of the present application does not limit the structure and material of the substrate 100 .

[0032] In addition, the present application does not limit the structure, size, etc. of the polygonal protrusions 110 and the gaps 120. For example, the polygonal protrusions 110 may be rectangular protrusions, square protrusions, pentagonal protrusions or hexagonal protrusions. Among them, for any polygonal protrusion 110, the shapes of its sides and tops may be the same or different; the height of its side cross section may be 1-10μm, and the width of the side cross section may be 2-300μm. Moreover, the width of the gap 120 between any two adjacent polygonal protrusions 110 may be 2-60μm. Among them, when the substrate 100 is placed on a horizontal plane, several polygonal protrusions 110 are perpendicular to the horizontal plane, and the side cross-sectional height (such as Figure 6 c in FIG. 1) is the height range of the plurality of polygonal protrusions 110 in the vertical direction; the side cross-sectional width (as shown in FIG. Figure 6 d in FIG. 1 ) is the width range of the plurality of polygonal protrusions 110 in the horizontal direction when the plurality of polygonal protrusions 110 are cut along the vertical direction.

[0033] For ease of explanation, the present application defines the ratio of the maximum cross-sectional width of each polygonal protrusion 110 to the maximum width of the gap 120 corresponding to the polygonal protrusion 110 as M. In order to ensure that the surface of the substrate 100 has a more uniform matte effect, the present application sets the ratio M within a first threshold value, so that the substrate 100 has a better matte anti-glare display effect. The first threshold range is 3%-20%, and the embodiment of the present application does not limit the specific value of the first threshold value.

[0034] Based on this, the matte anti-glare structure provided in the embodiment of the present application can reflect the light at the top of each polygonal protrusion 110 on the surface of the substrate 100 under the irradiation of an external light source to form a bright light area, and the gaps 120 formed between the polygonal protrusions 110 can form a dark light area with a brightness lower than that of the bright light area because the gaps 120 received less light. In this way, through the coordination between the bright light area and the dark light area, the substrate 100 can have a matte effect, and the anti-glare function of the substrate 100 can be achieved. In addition, the embodiment of the present application can flexibly adjust the structure or size of each polygonal protrusion 110 and the gap 120, so that the area, brightness, etc. of the bright light area and the dark light area formed on the surface of the substrate 100 can be precisely controlled, thereby making the substrate 100 have a variety of different matte effects, and it is beneficial to ensure that the substrate 100 has a more uniform haze, thereby improving the aesthetics of the product.

[0035] Specifically, regarding the various different matte effects formed on the surface of the substrate 100, please refer to the following different embodiments:

[0036] Embodiment 1

[0037] Figure 2This is a schematic diagram of a matte effect provided in Example 1 of the present application. Figure 2 The black lines in the figure represent the gap 120, and the white area surrounded by the black lines is the polygonal protrusion 110. Figure 2 As shown, by setting the widths of the plurality of gaps 120 to be the same, and making the difference between the maximum and minimum values ​​of the plurality of ratios M within a second threshold value, the second threshold value is 5%, that is, the difference between the maximum and minimum values ​​of the ratios M is less than 5%. And the plurality of ratios M corresponding to any two adjacent polygonal protrusions 110 are randomly distributed, so that the substrate 100 has a single matte effect.

[0038] For example, the width of the gap 120 can be set to 3 μm, and a number of polygonal protrusions 110 are randomly distributed on the surface of the substrate 100, the width of the side cross section is set to 33-60 μm, and the second threshold is set to 5%; by calculation, it can be obtained that the maximum value of the ratio M is 9%, the minimum value is 5%, and the difference between the maximum and minimum values ​​is 4%. In addition, since the sides of each polygonal protrusion 110 are set to different shapes, the ratios M corresponding to adjacent polygonal protrusions 110 are randomly distributed, so that evenly distributed bright and dark areas are formed on the surface of the substrate 100, and the matte effect is more uniform. No matter from which perspective the matte anti-glare structure is observed, a better appearance and display effect can be obtained.

[0039] Embodiment 2

[0040] Continue to refer to Figure 2 As shown, by setting the widths of the plurality of gaps 120 to be the same size, and setting the maximum cross-sectional widths of the plurality of polygonal protrusions 110 to be randomly distributed in the extension direction of the substrate 100, the substrate 100 has a single matte effect. The extension direction may be the extension direction when the substrate 100 is in a horizontal plane, such as Figure 2 The direction indicated by arrow A.

[0041] For example, the width of the gap 120 can be set to 3 μm, and the polygonal protrusions 110 are randomly distributed on the surface of the substrate 100, and the width of the side cross section is set to 33-60 μm. Compared with the above-mentioned embodiment 1, although the range of the contrast value M is not limited in the second embodiment, due to the random distribution of the polygonal protrusions 110, a uniform bright light area and dark light area can still be formed on the surface of the substrate 100, thereby achieving a single matte effect of the substrate 100. In addition, compared with the above-mentioned embodiment 1, the second embodiment has a simpler structure, reduced processing difficulty, and is conducive to improving production efficiency.

[0042] Embodiment 3

[0043] By setting the widths of the plurality of gaps 120 to be randomly distributed and setting the maximum cross-sectional widths of the plurality of polygonal protrusions 110 to be randomly distributed in the extension direction of the substrate 100, the substrate 100 has a single matte effect. The extension direction may be the extension direction when the substrate 100 is in a horizontal plane.

[0044] For example, the width of the plurality of gaps 120 can be set to a range of 2-60 μm, and the width of the side cross section of the plurality of polygonal protrusions 110 can be set to a range of 33-60 μm. The third embodiment is similar to the configuration provided in the second embodiment, but since the width of the plurality of gaps 120 is also set to a randomly distributed manner, the uniformity of the matte effect on the surface of the substrate 100 can be further improved, which is conducive to further improving the display effect of the matte anti-glare structure.

[0045] Embodiment 4

[0046] By setting the widths of the plurality of gaps 120 to be randomly distributed and setting the maximum cross-sectional widths of the plurality of polygonal protrusions 110 to be unidirectionally or periodically gradual in the extension direction of the substrate 100, the substrate 100 can have a gradual matte effect. The extension direction can be the extension direction when the substrate 100 is in a horizontal plane.

[0047] Among them, the unidirectional gradient can be a unidirectional increase or a unidirectional decrease, and the specific value of the increase or decrease can be reasonably selected according to the design requirements of the product, and the embodiments of the present application do not limit this. The periodic gradient can be a gradient (increase or decrease) according to a preset rule, and the preset rule can be set according to the length of the substrate 100 or the number of polygonal protrusions 110. For example, in the extension direction of the substrate 100, the surface of the substrate 100 is divided into a partition every 10 cm, and the maximum cross-sectional width of the polygonal protrusions 110 in the odd-numbered partitions is set to increase, and the maximum cross-sectional width of the polygonal protrusions 110 in the even-numbered partitions is set to decrease, so that a number of polygonal protrusions 110 present a periodic gradient; or,

[0048] In the extension direction of the substrate 100, all polygonal protrusions 110 are divided into multiple groups of 10 each, and the groups are numbered from left to right and from top to bottom. The maximum cross-sectional widths of the polygonal protrusions 110 in the groups with odd numbers are set to decrease, and the maximum cross-sectional widths of the polygonal protrusions 110 in the groups with even numbers are set to increase.

[0049] For example, the width of the plurality of gaps 120 may be set to a range of 2-60 μm, and the maximum cross-sectional width of the plurality of polygonal protrusions 110 may be set to decrease between 45 μm and 15 μm in the extension direction of the substrate 100. In this arrangement, since the widths of the plurality of gaps 120 are first set to be randomly distributed, the dark light areas formed on the surface of the substrate 100 are evenly distributed. However, since the size of the polygonal protrusions 110 is set to decrease in one direction, the area of ​​the bright light areas formed on the surface of the substrate 100 will also decrease in the extension direction of the substrate 100, thereby making the substrate 100 present a gradual matte effect as a whole.

[0050] Embodiment 5

[0051] Figure 3 This is a schematic diagram of a matte effect provided in Example 5 of the present application. Figure 3 The black lines in the figure represent the gaps, the white areas surrounded by the black lines are polygonal protrusions, and the thickness of the black lines corresponds to the change in the gap width. The extension direction may be the extension direction when the substrate 100 is in a horizontal plane, such as Figure 3 Direction indicated by the arrow.

[0052] Reference Figure 3 As shown, by setting the widths of multiple gaps 120 to the same size and setting the maximum cross-sectional widths of multiple polygonal protrusions 110 to be unidirectionally gradual or periodically gradual in the extension direction of the substrate 100, the substrate 100 has a gradual matte effect.

[0053] For example, the width of the gap 120 can be set to 6 μm, and the maximum cross-sectional width of the plurality of polygonal protrusions 110 can be set to decrease between 45 μm and 15 μm in the extension direction of the substrate 100. This setting is similar to the setting of the fourth embodiment. Since the widths of the plurality of gaps 120 are set to the same size, the dark light area on the surface of the substrate 100 can also be evenly distributed. Therefore, when the size of the polygonal protrusion 110 decreases in one direction, the area of ​​the bright light area formed on the surface of the substrate 100 will also decrease in the extension direction of the substrate 100, thereby making the substrate 100 present a gradual matte effect as a whole.

[0054] Embodiment 6

[0055] Figure 4 This is a schematic diagram of a matte effect provided in Example 6 of the present application. Figure 4 The black lines in the figure represent the gaps, the white area surrounded by the black lines is the polygonal protrusion, and the thickness of the black lines corresponds to the change in the gap width.

[0056] Reference Figure 4As shown, in the extension direction of the substrate 100, by setting multiple ratios M to be unidirectionally gradual or periodically gradual, the substrate 100 has a gradual matte effect. The extension direction may be the extension direction when the substrate 100 is in a horizontal plane, such as Figure 4 Direction indicated by the arrow.

[0057] For example, in the extension direction of the substrate 100, the width of all gaps 120 on the surface of the entire substrate 100 can be set to decrease unidirectionally between 4μm-2μm from left to right, and the maximum cross-sectional width of all polygonal protrusions 110 can be set to decrease unidirectionally between 45μm-15μm from left to right, and the multiple ratios M can increase unidirectionally between 8.9%-13% from left to right. Compared with the methods provided in the above-mentioned fourth and fifth embodiments, the sixth embodiment can make the gradual matte effect formed on the surface of the substrate 100 smoother by setting the ratio M to a unidirectional gradual change or a periodic gradual change, which is conducive to ensuring the aesthetics of the product.

[0058] Embodiment 7

[0059] In the extension direction of the substrate 100, the widths of the plurality of gaps 120 are set to be unidirectionally or periodically gradually changed, and the plurality of ratios M are set to be unidirectionally or periodically gradually changed, so that the substrate 100 has a gradual matte effect. The extension direction may be the extension direction when the substrate 100 is in a horizontal plane.

[0060] For example, the width of all gaps 120 on the entire surface of the substrate 100 can be set to decrease unidirectionally from left to right between 4 μm and 2 μm in the extension direction of the substrate 100, and the multiple ratios M can be set to decrease unidirectionally from left to right between 15% and 5%. At this time, the maximum cross-sectional width of the plurality of polygonal protrusions 110 increases unidirectionally from left to right between 26.7 μm and 40 μm, so that the bright area on the surface of the substrate 100 increases from left to right, and the dark area decreases from left to right, so that the substrate 100 has a gradual matte effect.

[0061] Embodiment 8

[0062] Figure 5 This is a schematic diagram of a matte effect provided in Example 8 of the present application. Figure 5 The black lines in the figure represent the gaps, the white area surrounded by the black lines is the polygonal protrusion, and the thickness of the black lines corresponds to the change in the gap width.

[0063] Reference Figure 5As shown, along the extension direction of the substrate 100, the widths of the plurality of gaps 120 are unidirectionally or periodically gradient, and the maximum cross-sectional widths of the plurality of polygonal protrusions 110 are randomly distributed, so that the substrate 100 has a gradient matte effect. The extension direction may be the extension direction when the substrate 100 is in a horizontal plane, such as Figure 5 Direction indicated by the arrow.

[0064] For example, in the extension direction of the substrate 100, the width of the plurality of gaps 120 is set to decrease unidirectionally between 6 μm and 3 μm from left to right, and the maximum cross-sectional width of the plurality of polygonal protrusions 110 is set to be randomly distributed. Since the bright light areas corresponding to the polygonal protrusions 110 are randomly distributed and the dark light areas corresponding to the gaps 120 decrease unidirectionally, the surface of the substrate 100 presents a gradual matte effect as a whole.

[0065] It is understandable that the configurations of the gap 120, the polygonal protrusion 110, and the ratio M provided in the above-mentioned embodiments 1 to 8 of the present application are only some specific examples for ease of understanding, and cannot constitute a limitation on the relevant contents in the embodiments of the present application. Of course, in addition to the above-mentioned different embodiments, those skilled in the art can also implement the methods not mentioned in the embodiments of the present application according to other combinations of the gap 120, the polygonal protrusion 110, and the ratio M, which will not be elaborated here one by one.

[0066] Figure 6 This is a schematic diagram of a polygonal protrusion with a rectangular top cross-section provided in an embodiment of the present application. Figure 7 A schematic diagram of an embodiment of the present application in which the cross-sectional shape of the top of a polygonal protrusion is an arc shape, Figure 8 A schematic diagram of a polygonal protrusion with a wavy top cross-sectional shape provided in an embodiment of the present application, Fig. 9 A schematic diagram of a polygonal protrusion provided in an embodiment of the present application having a sawtooth-shaped top cross-sectional shape.

[0067] In some possible implementations, refer to Figure 6-Figure 9 As shown, the cross-sectional shape of the top of each polygonal protrusion 110 can be one of a rectangular shape, a square shape, an arc shape, a wavy shape and a sawtooth shape.

[0068] Among them, when the cross-sectional shape of the top of the polygonal protrusion 110 is square or rectangular, the structure of the polygonal protrusion 110 is simple and easy to process; when the cross-sectional shape of the top of the polygonal protrusion 110 is wavy (or laser groove type), external light is irradiated on the top of the protrusion, and the external light can be diffracted under the action of the laser structure, so that the bright light area formed by the tops of several polygonal protrusions 110 has a color effect; when the cross-sectional shape of the top of the polygonal protrusion 110 is sawtooth (or slope), external light is irradiated on the top of the protrusion, and the external light can be emitted under the action of the slope structure, so that the bright light area formed by the tops of several polygonal protrusions 110 has a platinum texture.

[0069] Therefore, by setting the top of the polygonal protrusion 110 to a different structure or shape, the bright area can have different display effects, thereby making the appearance of the entire surface of the substrate 100 more diverse and expanding the application scope of the matte anti-glare structure.

[0070] In addition, an embodiment of the present application further provides a plate material, comprising a plate body and the above-mentioned matte anti-glare structure arranged on the plate body.

[0071] In addition, an embodiment of the present application further provides a glass, comprising a glass body and the above-mentioned frosted anti-glare structure arranged on the glass body.

[0072] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0073] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
