Referring to fig. 1, in an embodiment of the present invention, a method for manufacturing an anti-glare glass includes:
s1, imprinting a glass substrate in a softened state by using a prefabricated mold so as to form a lattice consisting of arrangement of rough points on the glass substrate, wherein the equal-area equivalent diameter of the projection of the rough points on the glass substrate is in the range of 2-20 microns, the distance between every two adjacent rough points is not more than 30 microns, and the rough points are concave points or convex points;
s2, cooling the glass substrate subjected to the imprinting treatment to obtain the anti-dazzle glass, wherein an anti-reflection layer is formed by the dot matrix.
The glass substrate may be embossed while in a temperature range corresponding to the softened state (e.g., typical glasses have a softening point temperature of 550-650 ℃). The softened state is a state in which the glass base material in a normal temperature state is heated to a temperature near the softening point temperature; or the glass melt may be cooled until its temperature reaches a temperature near the softening point, thereby obtaining a glass substrate in a softened state. It should be noted that, since the glass is amorphous, the softening point temperature is not an exact value and has a certain range of fluctuation, and when the softening point temperature is not reached, the glass is softened to some extent or after the softening point temperature is exceeded, the glass does not reach the desired softening degree. In the present invention, being in a softened state means that the glass substrate has been in a softened state, and the temperature at this time should be in the vicinity of the softening point temperature. The prefabricated mold can be a plate-shaped structure or a roller structure with a concave structure and/or a convex structure on the stamping surface, and the concrete conditions are selected according to the conditions of the actual size and the strength of the glass substrate. And carrying out imprinting treatment on the glass substrate in a softened state through a prefabricated mould so as to form a lattice consisting of coarse point arrangement on the glass substrate. The rough points are structures which destroy the flatness of the glass substrate; specifically, the bumps may protrude from the glass substrate or the pits may be recessed into the glass substrate. The roughness of the surface of the object can be generally characterized by using roughness parameters, commonly used roughness parameters include RSM (mean width of the particles) and RA (arithmetic mean deviation of the particles), RSM being the average value of the micro-unevenness intervals of the profile, in this embodiment, the RSM of a lattice consisting of rough points is 80-160 μm; RA means the arithmetic mean of the distances of the particles from the reference line in the thickness direction of the glass in the sampling length, and in this example, RA is 0.1 to 0.5 μm for a lattice consisting of coarse dots. The diameter of the rough spot is 5 to 20 μm. When the rough points are convex points, the rough points are convex glass structures protruding out of the stamping processing surface of the glass substrate; the rough point is a concave point which is a concave cavity concave to the stamping processing surface of the glass substrate.
In one step of implementing the preparation method, firstly, a glass base material is obtained after a glass raw material is subjected to sheet splitting treatment, and then the glass base material is subjected to shape treatment such as edging, opening and the like, and then is subjected to polishing treatment (mechanical polishing and/or chemical polishing) to obtain the glass base material with the qualified shape; heating the glass substrate with the standard appearance to the temperature near the softening point so as to enable the glass substrate to reach a softening state, and carrying out imprinting treatment on the glass substrate in the softening state by adopting a prefabricated mold so as to form a lattice consisting of coarse point arrangement on the glass substrate; and (3) carrying out cooling treatment on the glass substrate subjected to imprinting treatment to obtain the anti-glare glass, and then carrying out silk-screen printing, drying and cleaning to obtain the anti-glare glass product. Wherein, after the impression treatment is carried out to the glass substrate in the softening state, the temperature reduction treatment is followed. The temperature reduction treatment can be natural temperature reduction, and the anti-glare glass is obtained after the temperature reduction process is finished; and if the temperature reduction treatment is carried out by the tempering treatment, obtaining the toughened anti-glare glass after the temperature reduction process is finished. When the temperature reduction treatment is performed by the tempering treatment, the outer shape of the glass substrate is preferably the final size, otherwise, the tempered anti-glare glass is difficult to perform the outer shape processing again.
Usually, the outermost layer of the display screen assembly is a glass cover plate to protect the screen, and at the same time, some functional effects, such as AG-Anti-glare (Anti-glare), AF-Anti-fingerprint (Anti-fingerprint), or AR-Anti-reflection (Anti-reflection). Taking the Anti-glare treatment of the glass cover plate as an example, an AG-Anti-glare coating is attached to the glass cover plate or the glass cover plate is etched, so that the smooth surface of the glass cover plate is roughened to increase the proportion of diffuse reflection, thereby achieving the Anti-glare function. However, the uniformity of the roughness elements (grains in the AG-Anti-glare coating or the uneven elements in the etching layer) is not high whether the glass cover plate is roughened by means of an AG-Anti-glare coating or by means of an etching process. Along with the resolution ratio of display screen subassembly is higher and higher, when the interval homogeneity between the coarse unit size homogeneity itself and the coarse unit on the glass apron is relatively poor, in the display screen subassembly use, can produce the flash point phenomenon, seriously influences the visual effect of display screen subassembly.
The applicant finds that the reason for generating the flash point of the display screen assembly is that light rays emitted by the display screen in the display screen assembly are refracted by the rough units distributed on the surface of the anti-glare glass cover plate when passing through the anti-glare glass cover plate, so that a light condensation effect is generated, and the flash point phenomenon is formed. In the current display technology, a picture displayed in a display screen is composed of pixels arranged in an array, for example, an image with a resolution of 1920 × 1080 includes 1920 pixel units for each row and 1080 pixel units for each column, where each pixel unit includes an R sub-pixel, a G sub-pixel, and a B sub-pixel. For a 65 inch 8K display screen, the size of the sub-pixels of the pixel unit is about 60 μm. When the anti-glare treatment is not present on the glass cover plate, light rays emitted by each sub-pixel in the display screen can directly enter eyes of a user.
When the rough elements are present on the glass cover plate, uneven coverage of the sub-pixels by the rough elements can also cause light entering the user's eyes to deviate from the actual requirements. If the distance between the rough points is large, there may be a case where part of the sub-pixels are blocked and part of the sub-pixels are not blocked at all, and a flash point may be generated. This is why the higher the resolution of the display screen, the more likely it is that the anti-glare treatment is applied to it, the more the flash point phenomenon occurs. In this embodiment, the distance between the rough points is controlled to be less than 30 μm, and each sub-pixel (about 60 μm) corresponds to two or more rough points, so that the possibility of the rough points forming non-uniform coverage on the sub-pixels is greatly reduced, and the probability of generating flash points is also reduced. And the rough points are processed in an embossing mode, so that various size requirements can be met. It should be noted that the distance between adjacent rough points is controlled more directly and accurately by the prefabricated mold, and the RSM value is a test value, and the actual distance between the rough points is controlled more directly and accurately by directly using different prefabricated molds relative to the spacing parameter for representing the rough points by using the RSM value.
According to the preparation method of the anti-glare glass, the prefabricated mold is adopted to imprint the lattice formed by the arrangement of the rough points on the glass substrate, and the preparation method has the advantages of simplicity, reliability, low cost, high yield and high controllability; and the distance between the rough points is controlled to be less than 30 μm, the probability of the rough points forming non-uniform coverage on the sub-pixels is reduced, and the probability of flash point generation is reduced.
In one embodiment, the rough spots are offset from the imprint-treated side of the glass substrate by a dimension in a range of 0.2 to 1.5 μm.
For example, when the rough point is a conical bump, the highest point is in the range of 0.2 to 1.5 μm from the plane of the glass substrate; when the asperities are conical depressions, the lowest point thereof is in the range of 0.2 to 1.5 μm from the planar size of the glass substrate. It should be noted that the above-mentioned rough points are not limited to regular shapes such as cones or pyramids. When the anti-glare glass is applied to the display module, the size range of 0.2-1.5 mu m ensures that the anti-glare effect is formed, and the display effect of the display module is not influenced.
In one embodiment, the free end of the asperity remote from the glass substrate imprinting surface is spherical or ellipsoidal.
When the rough points are convex points, the rough points are convex glass structures protruding out of the stamping processing surface of the glass substrate; the rough point is a concave point which is a concave cavity concave to the stamping processing surface of the glass substrate. When the rough points are concave points, the bottom of the concave cavity is spherical or ellipsoidal, the structure for forming the concave points on the prefabricated mold is a convex structure, the top end of the convex structure is spherical or ellipsoidal correspondingly, and the possibility of damaging the glass substrate by the prefabricated mold is reduced in the process of impressing the glass substrate by the prefabricated mold; when the rough points are convex points, the top of the protruded glass structure body is in a spherical or ellipsoidal shape, the structure for forming the convex points on the prefabricated mold is in a concave structure, the bottom of the concave structure is correspondingly in a spherical or ellipsoidal shape, the possibility of damage of the prefabricated mold to the glass substrate is reduced in the process of impressing the prefabricated mold to the glass substrate, and the smoothness of the antireflection layer can be improved to a certain extent under the protection effect. It is noted that when a particle layer is attached to a glass substrate to provide an anti-glare effect, the particles in the particle layer are more refractive to incident light (due to the shape of the particles and the density difference between the particles and the glass substrate); in the present embodiment, the rough points and the glass substrate are made of the same material, so that the incident light is less refracted, and the generation of the flash point phenomenon can be reduced.
In one embodiment, the step of performing an imprinting process on the glass substrate in a softened state by using a prefabricated mold to form a lattice consisting of a coarse dot arrangement on the glass substrate comprises:
and cooling the glass melt until the glass substrate in a softened state is obtained.
The purpose of the steps is to directly carry out the imprinting treatment when the temperature of the glass melt is reduced to be close to the softening point temperature in the production process of the glass base material, so that the glass base material is not heated to be close to the softening point temperature again in order to carry out the imprinting treatment on the glass base material in a normal temperature state. In order to improve the efficiency of the production process, the size of the glass substrate is preferably selected to be larger, and after the anti-reflection layer is processed on the glass substrate, when the anti-glare glass is required to be applied to a specific product, the anti-glare glass is subjected to sheet opening treatment with a proper size.
In one embodiment, the step of performing an imprinting process on the glass substrate in a softened state using a prefabricated mold to form a lattice of roughened dot arrangements on the glass substrate comprises:
the glass base material at normal temperature is subjected to heat treatment to obtain a glass base material in a softened state.
The glass substrate can be a glass substrate material with a proper size obtained after the sheet opening treatment, so that the glass substrate subjected to the stamping treatment is a glass substrate with a proper size; the glass substrate may be a large glass substrate material which has not been subjected to the cutting process, and the glass substrate subjected to the embossing process may be subjected to the cutting process. When the glass substrate is in the size subjected to the sheet-opening treatment, the size is small, and the pressure applied when the glass substrate is subjected to the imprinting treatment is small, which is advantageous for processing; if the glass substrate is of a size that does not undergo the sheet-opening process, the efficiency of the overall process is high when the glass substrate is subjected to the imprint process.
In one embodiment, the step of subjecting the glass substrate subjected to the imprint treatment to a temperature reduction treatment to obtain the anti-glare glass comprises:
and carrying out temperature reduction treatment on the glass substrate subjected to the imprinting treatment by using a tempering treatment process to obtain the anti-glare glass.
The temperature of the stamping treatment is near the softening point temperature, when the temperature is reduced to be lower than the softening point temperature, the temperature reduction process of the toughening treatment is started, the stamping treatment and the toughening treatment are carried out in sequence, the temperature does not need to be raised for the toughening treatment again independently, the energy waste is reduced, and the efficiency of the preparation method is improved. Of course, the size of the glass substrate needs to be the application size of the final product, and since the tempering treatment is directly started after the imprinting treatment is completed, the sheet cutting treatment cannot be performed after the tempering treatment.
In one embodiment, the step of subjecting the glass substrate subjected to the imprinting treatment to a temperature reduction treatment to obtain the anti-glare glass further comprises:
and attaching a functional film layer on the antireflection surface layer.
In the step S1, the prefabricated mold forms a lattice consisting of coarse point arrangement on the glass substrate in the softening state, and in the step S2, after the glass substrate is subjected to cooling treatment, the lattice is cooled together to form the antireflection surface layer. And processing a functional film layer on the antireflection surface layer so as to enable the glass substrate to realize functions except for anti-glare. The functional film layer may be AF-Anti-fingerprint film layer or AR film layer.
In one embodiment, the step of attaching a functional film layer on the antireflection coating comprises:
attaching an anti-fingerprint film layer forming agent to the anti-reflection surface layer, wherein the anti-fingerprint film layer forming agent comprises fluoride, matrix resin and a curing agent;
and drying the glass substrate.
In this embodiment, the functional film layer is an AF-Anti-fingerprint film layer, specifically, an AF-Anti-fingerprint functional liquid is sprayed on the Anti-reflection surface layer, and then the glass substrate is dried, so as to obtain the AF-Anti-fingerprint film layer. In certain embodiments, the composition of the AF-Anti-fingerprint film layer may be: 20% -25% of fluoride, matrix resin: 15% -20%, curing agent: 1 to 3 percent. In some embodiments, the pressure of the spray gun may be 5MPa-7MPa, the flow rate is 10g/30 s-15 g/30 s, the coating needs to be baked for 30min, and the temperature is about 150 ℃, so that the anti-fingerprint layer is covered on the anti-glare layer. In many cases, the functional liquid for forming the functional film layer includes a suspension medium and a functional powder dispersed in the suspension medium. Because the dot matrix is obtained by the impression treatment of the prefabricated mould, the dot matrix formed by the arrangement of the rough points on the antireflection surface layer is more uniform, an excellent powder hanging effect can be formed, the distribution of the functional liquid on the glass substrate is favorable, and the functional effect of the formed functional film layer is better. Particularly, when the size of the concave points or the convex points in the dot matrix is small and the distribution is uniform, the powder hanging effect provided by the dot matrix is better, and the distribution effect of the functional liquid on the dot matrix is better.
The invention also provides the anti-glare glass obtained by the preparation method.
The anti-glare glass obtained by the preparation method of the anti-glare glass has the advantages of simplicity, reliability, low cost, high yield and high controllability, and the distance between the rough points is controlled to be less than 30 mu m, so that the possibility of non-uniform coverage of the rough points on the sub-pixels is reduced, and the probability of flash points is reduced.
The invention also provides a liquid crystal display module which comprises a liquid crystal display screen and the anti-dazzle glass; the anti-glare glass is arranged on the upper surface of the liquid crystal display screen.
The liquid crystal display module with the anti-dazzle glass as the cover plate has a good anti-dazzle effect, and the flash point effect is improved.
In one embodiment, the arrangement direction of the rough dots in the dot matrix is consistent with the arrangement direction of the pixels in the liquid crystal display screen.
For example, the pixel arrangement direction in the liquid crystal display screen is a rectangular array, and specifically the pixel arrangement direction is arranged in a horizontal direction and a vertical direction; the arrangement direction of the rough points in the dot matrix on the anti-glare glass is also a rectangular array, and the rough points are also arranged in an array in two directions, namely a horizontal direction and a vertical direction, in the liquid crystal display screen. As described above, the effect of flash points is exacerbated by the irregular occlusion of a subpixel by a matte point in a pixel. In this embodiment, the arrangement rule of the rough points is consistent with that of the pixels, so that the probability of irregular shielding of the rough points on the sub-pixels is reduced.
