技术领域technical field
本说明书涉及显示设备技术领域，尤其涉及一种显示屏的玻璃盖板及其制备方法。The present specification relates to the technical field of display devices, and in particular, to a glass cover plate of a display screen and a preparation method thereof.
背景技术Background technique
为了避免外部光源照射到电子设备屏幕上产生较强的反射光，对用户造成干扰，导致用户无法看清屏幕，通常会在电子设备的显示屏上面覆盖一层玻璃盖板，用于实现防眩光的功能，用于防眩光的玻璃盖板表面通常比较粗糙，使照射到屏幕的光线发生漫反射，降低反射光强度。现有的防眩光的玻璃盖板一般是通过在玻璃基板喷涂防眩光涂层，或者对玻璃基板进行化学蚀刻，以便在玻璃基板表面形成一些颗粒，使表面呈凹凸结构，增加表面的粗糙度。通常玻璃基板上形成的颗粒分布比较随机，尺寸也比较大，对于以往分辨率较低的显示屏，不存在影响，但是随着显示屏分辨率越来越高，搭配这种表面颗粒分布比较随机、尺寸较大的防眩光玻璃盖板使用时，会产生闪点现象，影响屏幕的视觉效果。In order to prevent the external light source from irradiating the screen of the electronic device to generate strong reflected light, causing interference to the user and causing the user to be unable to see the screen clearly, a glass cover is usually covered on the display screen of the electronic device to achieve anti-glare. The surface of the glass cover used for anti-glare is usually rough, so that the light hitting the screen is diffusely reflected and the intensity of the reflected light is reduced. The existing anti-glare glass cover plate is generally by spraying the anti-glare coating on the glass substrate, or chemically etching the glass substrate, so as to form some particles on the surface of the glass substrate, so that the surface has a concave-convex structure, and the surface roughness is increased. Usually, the distribution of particles formed on the glass substrate is relatively random and the size is relatively large. It has no effect on the display screen with lower resolution in the past. However, as the resolution of the display screen is getting higher and higher, the distribution of particles on the surface is relatively random. , When the anti-glare glass cover with a larger size is used, a flash point phenomenon will occur, which will affect the visual effect of the screen.

通常，如图1所示，电子设备的显示屏11上会覆盖一层防眩光玻璃盖板12，防眩光玻璃盖板12表面一般比较粗糙，使照射到屏幕的光线发生漫反射，降低反射光强度，避免反射光太强影响视觉效果。目前，防眩光玻璃盖板可以通过在玻璃基板喷涂防眩光涂层，或者对玻璃基板进行化学蚀刻，以便在玻璃基板表面形成一些颗粒，使表面呈凹凸结构，增加表面的粗糙度。比如，通过在玻璃基板表面喷涂防眩光涂层后，玻璃基板上会分布一些涂层颗粒，使玻璃基板表面形成一定的粗糙度。目前，不论是通过喷涂防眩光涂层还是通过化学蚀刻的方式在玻璃基板上形成的颗粒分布都比较随机，尺寸也比较大，对于以往分辨率较低的显示屏，比如分辨率为2K的显示屏，使用过程中不会出现问题，但是，随着显示屏分辨率越来越高，比如，现在的显示屏分辨率都达到4K甚至是8K，在搭配这种表面颗粒分布比较随机、尺寸较大的防眩光玻璃盖板使用时，会产生闪点现象，严重影响屏幕的视觉效果。Usually, as shown in FIG. 1, the display screen 11 of the electronic device is covered with a layer of anti-glare glass cover 12. The surface of the anti-glare glass cover 12 is generally rough, so that the light irradiating the screen is diffusely reflected and the reflected light is reduced. Intensity, to avoid the reflected light is too strong to affect the visual effect. At present, the anti-glare glass cover plate can be sprayed with an anti-glare coating on the glass substrate, or chemically etched on the glass substrate, so as to form some particles on the surface of the glass substrate, so that the surface has a concave-convex structure and increase the roughness of the surface. For example, after spraying the anti-glare coating on the surface of the glass substrate, some coating particles will be distributed on the glass substrate to form a certain roughness on the surface of the glass substrate. At present, the distribution of particles formed on the glass substrate by spraying anti-glare coating or chemical etching is relatively random and the size is relatively large. However, as the resolution of the display screen is getting higher and higher, for example, the current display screen resolution has reached 4K or even 8K, the particle distribution on this surface is relatively random and the size is relatively small. When a large anti-glare glass cover is used, a flash point phenomenon will occur, which will seriously affect the visual effect of the screen.
申请人发现，产生闪点的原因是显示屏发出的光线通过防眩光玻璃盖板表面时，会被防眩光玻璃盖板表面分布的颗粒折射，从而产生聚光作用，形成闪点现象。以下结合图2具体解释闪点现象产生的原理。如图2中的(a)所示，为显示屏上的玻璃盖板表面光滑即不存在颗粒时，显示屏的光线透过玻璃盖板到达人眼的示意图。一般而言，显示屏中显示的画面可以看成由大量像素构成，比如，分辨率为1920×1080的图像，可以看成每行包括1920个像素，每列包括1080个像素，本申请中将每个像素称为显示屏的像素单元，其中，每个像素单元又包括大小相同的三个子像素，分别为R子像素、G系像素、B子像素，三个子像素分别显示红、绿、蓝三种颜色的光线。从图2中的(a)可知，显示屏上的玻璃盖板表面不存在颗粒时，显示屏中每个像素单元中的R子像素、G子像素、B子像素产生的光线透过玻璃盖板的透光量一致，从而最后到达人眼中的不同颜色的光线的量一致，人眼看到的即为正常的白色。如图2中的(b)和(c)所示，显示屏中每个像素单元中的R子像素、G子像素、B子像素产生的光线 透过具有粗糙表面的玻璃盖板的示意图，从图中可知，由于玻璃盖板上的颗粒分布不均匀，像素单元的有些子像素对应的玻璃盖板表面有颗粒，像素单元的有些子像素对应的玻璃盖板表面不存在颗粒，当像素单元的子像素对应的玻璃盖板表面存在颗粒时，光线会被颗粒折射，导致最终达到人眼的不同颜色的光线的量不均匀，最终呈现的颜色不是白色，而是偏红色或者偏蓝色，从而产生闪点现象，影响视觉效果。此外，由于目前的技术，在玻璃盖板上形成的颗粒分布不均匀，且尺寸较大，远远大于显示屏的每个像素单元的子像素的尺寸，如图2中的(d)所示，导致最终每个像素单元的子像素对应的玻璃盖板表面分布的颗粒的情况差异较大，各像素单元的子像素产生的光线透过玻璃盖板的量也存在较大差异，不同颜色的光线非常不均匀，从而导致闪点现象严重。The applicant has found that the reason for the flash point is that when the light emitted by the display screen passes through the surface of the anti-glare glass cover, it will be refracted by the particles distributed on the surface of the anti-glare glass cover, thereby generating light focusing and forming a flash point phenomenon. The principle of the generation of the flash point phenomenon will be explained in detail below with reference to FIG. 2 . As shown in (a) of FIG. 2 , it is a schematic diagram of the light from the display screen reaching the human eye through the glass cover when the surface of the glass cover on the display screen is smooth, that is, there are no particles. Generally speaking, the picture displayed on the display screen can be regarded as composed of a large number of pixels. For example, an image with a resolution of 1920×1080 can be regarded as including 1920 pixels in each row and 1080 pixels in each column. Each pixel is called a pixel unit of the display screen, and each pixel unit includes three sub-pixels with the same size, namely R sub-pixel, G-series pixel, and B sub-pixel. The three sub-pixels display red, green, and blue respectively. Three colors of light. It can be seen from (a) in Figure 2 that when there are no particles on the surface of the glass cover on the display screen, the light generated by the R sub-pixels, G sub-pixels, and B sub-pixels in each pixel unit in the display screen passes through the glass cover The amount of light transmittance of the board is the same, so that the amount of light of different colors that finally reach the human eye is the same, and what the human eye sees is normal white. As shown in (b) and (c) in Figure 2, a schematic diagram of the light generated by the R sub-pixel, G sub-pixel, and B sub-pixel in each pixel unit in the display screen passing through a glass cover plate with a rough surface, It can be seen from the figure that due to the uneven distribution of particles on the glass cover, there are particles on the surface of the glass cover corresponding to some sub-pixels of the pixel unit, and there are no particles on the surface of the glass cover corresponding to some sub-pixels of the pixel unit. When there are particles on the surface of the glass cover corresponding to the sub-pixels, the light will be refracted by the particles, resulting in uneven amounts of light of different colors that finally reach the human eye, and the final color is not white, but reddish or bluish. As a result, a flash point phenomenon occurs, which affects the visual effect. In addition, due to the current technology, the particles formed on the glass cover plate are unevenly distributed and larger in size, far larger than the size of the sub-pixels of each pixel unit of the display screen, as shown in (d) in Figure 2 , resulting in a large difference in the distribution of particles on the surface of the glass cover plate corresponding to the sub-pixels of each pixel unit, and the amount of light generated by the sub-pixels of each pixel unit passing through the glass cover plate also has a large difference. The light is very uneven, resulting in severe flash points.
为了实现电子设备的显示屏既能达到防眩光效果，又不会产生严重的闪点现象，申请人深入研究了显示屏的玻璃盖板上的颗粒的尺寸对闪点现象的影响。经过大量试验，申请人发现，如果显示屏的玻璃盖板上的颗粒分布不均匀，或者颗粒的平均宽度(RSM)大于显示屏的像素单元的子像素的尺寸，会导致每个像素单元的子像素对应的玻璃盖板表面颗粒的分布情况差异较大，从而导致不同子像素产生的光线透过玻璃盖板的透光量不同，不同颜色的光线(比如，R、G、B)透过玻璃盖板的透光量不一样，闪点现象比较严重。In order to realize that the display screen of electronic equipment can achieve anti-glare effect without serious flash point phenomenon, the applicant has deeply studied the influence of the particle size on the glass cover plate of the display screen on the flash point phenomenon. After extensive experiments, the applicant found that if the distribution of particles on the glass cover of the display screen is not uniform, or if the average width (RSM) of the particles is larger than the size of the sub-pixels of the pixel unit of the display screen, the sub-pixels of each pixel unit will be The distribution of the particles on the surface of the glass cover plate corresponding to the pixels is quite different, resulting in different light transmission amounts of the light generated by different sub-pixels passing through the glass cover plate, and light of different colors (for example, R, G, B) passing through the glass The light transmittance of the cover is different, and the flash point phenomenon is more serious.
而当颗粒在玻璃盖板表面均匀分布，且每个子像素对应玻璃盖板表面颗粒分布情况差异较小时，则不同颜色的子像素产生的光线透过玻璃盖板的透光量差异较小，可以大大减少闪点现象。如图3所示，示出了当颗粒的平均宽度RSM与像素单元的子像素的尺寸一致且均匀分布的场景，从图中可知，每个像素单元对应的玻璃盖板表面颗粒的分布情况基本一致(即对应的凹起和平整部分一致)，从而不同像素单元产生的不同颜色的光线透过玻璃盖板的透光量一致，可以避免闪点现象。However, when the particles are uniformly distributed on the surface of the glass cover, and each sub-pixel corresponds to a small difference in particle distribution on the surface of the glass cover, the difference in the amount of light transmitted through the glass cover by the light generated by the sub-pixels of different colors is small. Greatly reduce flash point phenomenon. As shown in Figure 3, it shows a scene when the average width RSM of the particles is consistent with the size of the sub-pixels of the pixel unit and is evenly distributed. It can be seen from the figure that the distribution of particles on the surface of the glass cover corresponding to each pixel unit is basically Consistent (that is, the corresponding concave and flat parts are the same), so that the light transmittances of different colors of light generated by different pixel units passing through the glass cover are the same, and the phenomenon of flash point can be avoided.
当然，图3所示出的只是理想情况下场景，理想情况下颗粒在玻璃盖板上可以均匀分布，颗粒的宽度也基本一致，但在实际应用中，由于制造工艺的限制，颗粒在玻璃盖板上分布的均匀度会受到一定的限制，且颗粒自身的形态和 结构也不可能完全一致，多少会存在一定的差异。申请人发现，每个像素单元对应的玻璃盖板表面分布的颗粒的整体情况差异越小，则不同颜色的光线的透光量的差异也越小，越不容易出现闪点现象。而当玻璃盖板上的颗粒的平均宽度相对于显示屏的像素单元的子像素的尺寸越小时，则每个像素单元对应的玻璃盖板表面分布的颗粒的差异也越小，越不容易出现闪点现象。申请人通过大量的试验发现，实际使用中，当防眩光层上的颗粒的RSM小于或等于显示屏的像素单元的子像素的尺寸的一半时，则每个子像素对应的玻璃盖板表面分布的颗粒即便存在差异，差异也比较小，基本上可以很好的避免闪点问题，大大提升显示效果。如图4所示，为防眩光层颗粒的RSM等于显示屏的的子像素的尺寸的一半时的场景，可见每个子像素对应的玻璃盖板表面上的颗粒分布比较一致，当颗粒尺寸更小时，差异会越来越小。Of course, what is shown in Figure 3 is only an ideal scenario. Ideally, the particles can be evenly distributed on the glass cover, and the width of the particles is basically the same. However, in practical applications, due to the limitations of the manufacturing process, the particles are on the glass cover. The uniformity of the distribution on the plate will be limited to a certain extent, and the shape and structure of the particles themselves may not be completely consistent, and there will be some differences. The applicant found that the smaller the overall difference of the particles distributed on the surface of the glass cover plate corresponding to each pixel unit, the smaller the difference in the transmittance of light of different colors, and the less likely the flash point phenomenon will occur. When the average width of the particles on the glass cover plate is smaller than the size of the sub-pixels of the pixel unit of the display screen, the difference of the particles distributed on the surface of the glass cover plate corresponding to each pixel unit is also smaller, and it is less likely to appear. flash point phenomenon. The applicant has found through a large number of experiments that in actual use, when the RSM of the particles on the anti-glare layer is less than or equal to half the size of the sub-pixels of the pixel unit of the display screen, the distribution of the surface of the glass cover corresponding to each sub-pixel is Even if there is a difference in the particles, the difference is relatively small, which can basically avoid the flash point problem and greatly improve the display effect. As shown in Figure 4, it is a scene when the RSM of the anti-glare layer particles is equal to half the size of the sub-pixels of the display screen. It can be seen that the distribution of particles on the surface of the glass cover corresponding to each sub-pixel is relatively consistent. When the particle size is smaller , the difference will be smaller and smaller.

In order to avoid the flash point phenomenon, the RSM of the particles of the anti-glare layer on the glass cover can be controlled to be less than or equal to half of the sub-pixel size of the pixel unit of the display screen. The size of the pixel is about 120 μm, and thus, the size of the particles can be controlled to be less than or equal to 60 μm.

本申请中的颗粒可以是通过一定的物理或者化学手段在玻璃盖板表面形成的具有一定轮廓形状的微观的凹点或者凸点，这些凹点或者凸点在玻璃盖板表 面均匀分布，以降低玻璃盖板表面的平整度。比如，颗粒可以是通过在玻璃盖板表面喷涂涂层形成的涂层颗粒，也可以使通过蚀刻或者其他方法在玻璃表面形成的均匀分布的凹凸结构。颗粒可以呈现各种微观形态，如图6所示，示出了颗粒的几种微观形态，当然，颗粒的具体形态结构不局限于图6(a)中示出的几种，只要可以使玻璃盖板表面呈现凹凸起伏的结构，形成一定的粗糙度即可，本申请不做限制。The particles in this application may be microscopic concave or convex points with a certain contour and shape formed on the surface of the glass cover by certain physical or chemical means. These concave or convex points are evenly distributed on the surface of the glass cover to reduce The flatness of the glass cover surface. For example, the particles may be coating particles formed by spray coating on the surface of the glass cover plate, or may be uniformly distributed concavo-convex structures formed on the glass surface by etching or other methods. The particles can take on various microscopic forms, as shown in Figure 6, which shows several microscopic forms of the particles. Of course, the specific morphological structure of the particles is not limited to those shown in Figure 6(a), as long as the glass can be The surface of the cover plate presents a concave-convex structure, and a certain roughness may be formed, which is not limited in this application.
通常可以采用粗糙度参数来表征物体表面的粗糙度，常用的粗糙度参数包括RSM和RA，其中，RSM表示颗粒的平均宽度，是指在取样长度内，两个颗粒之间的距离的平均值，RA表示颗粒算术平均偏差，是指在取样长度内，沿玻璃厚度方向上颗粒与基准线的距离的算术平均值。如图6(b)所示，示出了某个取样长度内，两个颗粒之间的间距，假设分别为x1、x2、x3、x4、x5，则颗粒的平均宽度RSM＝(x1+x2+x3+x4+x5)/5。如图6(c)所示，示出了某个取样长度内，颗粒在玻璃厚度方向上与基准线的距离，假设分别为a1、a2、a3、a4、a5(图中只示出a1，a2、a3、a4、a5未示出),则颗粒与基准线的距离的算术平均偏差RA＝(a1+a2+a3+a4+a5)/5。Roughness parameters can usually be used to characterize the surface roughness of an object. Commonly used roughness parameters include RSM and RA, where RSM represents the average width of particles, which refers to the average distance between two particles within the sampling length. , RA represents the arithmetic mean deviation of the particles, which refers to the arithmetic mean of the distances between the particles and the reference line in the direction of the thickness of the glass within the sampling length. As shown in Figure 6(b), it shows the distance between two particles within a certain sampling length. Assuming that they are x1, x2, x3, x4, and x5, respectively, the average width of the particles RSM=(x1+x2 +x3+x4+x5)/5.

在某些实施例中，玻璃盖板的防眩层可以通过在玻璃盖板表面喷涂防眩光涂层制备得到，在玻璃盖板上喷涂防眩光涂层时，应严格控制防眩光涂层颗粒的大小以及分布均匀度，以保证通过防眩光涂层颗粒在玻璃盖板表面形成的颗粒的平均宽度小于或等于显示屏的像素单元的子像素的尺寸的一半。In some embodiments, the anti-glare layer of the glass cover plate can be prepared by spraying the anti-glare coating on the surface of the glass cover plate. When spraying the anti-glare coating on the glass cover plate, the particle size of the anti-glare coating should be strictly controlled. Size and distribution uniformity to ensure that the average width of the particles formed by the anti-glare coating particles on the surface of the glass cover plate is less than or equal to half the size of the sub-pixels of the pixel unit of the display screen.
在某些实施例中，为了更精确地控制防眩光层的颗粒的分布的均匀性以及颗粒的平均宽度，也可以通过对玻璃基板进行化学蚀刻处理，以得到防眩光层。在某些实施例中，可以对玻璃基板进行蒙砂处理以在所述玻璃基板生成防眩光层，得到所述玻璃盖板，其中，蒙砂处理的具体过程如下：In some embodiments, in order to more precisely control the uniformity of particle distribution and the average width of the particles in the anti-glare layer, the anti-glare layer may also be obtained by chemically etching the glass substrate. In some embodiments, frosting treatment may be performed on the glass substrate to generate an anti-glare layer on the glass substrate to obtain the glass cover plate, wherein the specific process of the frosting treatment is as follows:
采用喷淋设备将蒙砂粉均匀喷洒至所述玻璃基板，以在所述玻璃基板表面覆盖均匀分布的蒙砂粉；The frosting powder is evenly sprayed onto the glass substrate by spraying equipment, so as to cover the surface of the glass substrate with the frosting powder evenly distributed;
采用喷淋设备将酸液喷洒至覆盖有所述蒙砂粉的玻璃基板上，以在所述玻璃基板形成防眩光层，所述防眩光层包括均匀分布的颗粒以形成一定的粗糙度；The acid solution is sprayed onto the glass substrate covered with the frosting powder by using a spraying device, so as to form an anti-glare layer on the glass substrate, and the anti-glare layer includes uniformly distributed particles to form a certain roughness;
其中，所述喷淋设备喷头的孔径为小于或等于20μm，以控制所述颗粒的平均宽度小于60μm。Wherein, the pore diameter of the spray head of the spray equipment is less than or equal to 20 μm, so as to control the average width of the particles to be less than 60 μm.
通常，为了在玻璃表面形成一定的粗糙度，会采用化学蚀刻的方式对玻璃基板进行处理，以便在玻璃基板表面形成凹凸不平的轮廓结构。化学蚀刻主要是通过对玻璃基板进行蒙砂处理，蒙砂处理的主要原理是通过酸液与玻璃反应，从而对玻璃表面进行化学腐蚀以形成粗糙面，通常对玻璃基板进行腐蚀用到的酸液为氢氟酸，以下为氢氟酸与玻璃反应化学式:Usually, in order to form a certain roughness on the glass surface, the glass substrate is processed by chemical etching, so as to form an uneven profile structure on the surface of the glass substrate. Chemical etching is mainly performed by frosting the glass substrate. The main principle of the frosting treatment is to chemically corrode the glass surface to form a rough surface through the reaction between acid and glass. Usually, the acid used to corrode the glass substrate It is hydrofluoric acid, and the following is the chemical formula of the reaction between hydrofluoric acid and glass:
aNa 2O·bK 2O·cPbO·dCaO·eMgO·fSiO 2+(2a+2b+2c+2d+2e+4f)HF→aNa 2SiF6+bK 2SiF 6+cPbF 2+dCaF 2+eMgF 2+[f-(a+b)]SiF 4+(a+b+c+d+e+2f)H 2O - aNa 2 O·bK 2 O·cPbO·dCaO·eMgO·fSiO 2 +(2a+2b+2c+2d+2e+4f)HF→aNa 2 SiF6+bK 2 SiF 6 +cPbF 2 +dCaF 2 +eMgF 2 + [f-(a+b)]SiF 4 +(a+b+c+d+e+2f)H 2 O -
玻璃的主要成分为硅酸盐，硅酸盐与氢氟酸反应，生成的氟化钙、氟化钡、氟化铅等氢氟酸盐不溶于水。The main component of glass is silicate. Silicate reacts with hydrofluoric acid, and the resulting hydrofluoric acid salts such as calcium fluoride, barium fluoride and lead fluoride are insoluble in water.
在蚀刻过程中，通过化学反应的生成难溶物，会黏附于玻璃基板的表面，随着反应时间延长，反应物堆积成颗粒状晶体附着于玻璃基板表面，有反应物粘附的玻璃基板表面阻碍了腐蚀液的进一步腐蚀，从而最终在玻璃基板表面形成凹凸不平的晶状颗粒，使玻璃基板由光滑面变成粗糙面，该粗糙面对入射光产生散射作用，呈半透明状态而有朦胧的感觉，故称为蒙砂。During the etching process, insoluble substances generated by chemical reactions will adhere to the surface of the glass substrate. With the prolongation of the reaction time, the reactants accumulate into granular crystals and adhere to the surface of the glass substrate. The surface of the glass substrate with the reactants adhered It hinders the further corrosion of the etchant, so as to eventually form uneven crystalline particles on the surface of the glass substrate, so that the glass substrate changes from a smooth surface to a rough surface, and the rough surface scatters the incident light, which is translucent and hazy feeling, so called frosting.
通常，氢氟酸可以通过氟化物与盐酸、硫酸等反应制备得到。所以，在蒙砂处理过程中，相关技术采用直接将玻璃基板浸泡到由氟化物、盐酸或者硫酸等组成的蚀刻液当中，以利用氟化物与盐酸或者硫酸生成的氢氟酸对玻璃基板进行腐蚀，或者将由氟化物、盐酸或者硫酸等组成的蚀刻液通过喷淋设备喷洒至玻璃基板上，以对玻璃基板进腐蚀，上述方式无法很好地控制在玻璃基板表面生成的颗粒的尺寸以及颗粒分布的均匀度，往往制备得到的玻璃盖板表面颗粒分布不均匀，且尺寸较大。Generally, hydrofluoric acid can be prepared by reacting fluoride with hydrochloric acid, sulfuric acid, etc. Therefore, in the frosting process, the related art directly immerses the glass substrate in an etching solution composed of fluoride, hydrochloric acid or sulfuric acid, so as to use the hydrofluoric acid generated by fluoride and hydrochloric acid or sulfuric acid to corrode the glass substrate , or spray the etching solution composed of fluoride, hydrochloric acid or sulfuric acid on the glass substrate through spray equipment to corrode the glass substrate, the above method cannot well control the size and particle distribution of the particles generated on the surface of the glass substrate The uniformity of the prepared glass cover plate is often uneven and the particle size is large.
为了得到均匀分布且尺寸符合需求的颗粒，本申请在对玻璃基板进行蒙砂处理时，先通过喷淋设备将蒙砂粉均匀喷洒至玻璃基板的表面，以在玻璃基板表面均匀的覆盖一层蒙砂粉，然后通过喷淋设备将酸液喷洒至玻璃基板表面的 蒙砂粉上，以便蒙砂粉与酸液反应生成氢氟酸，氢氟酸再与玻璃基板反应，在玻璃基板表面形成均匀分布的颗粒，即颗粒，以在玻璃盖板表面形成一定的粗糙度，对光线可以产生散射作用，从而实现防眩光的效果。同时，为了控制颗粒的尺寸小于或等于显示屏像素单元的子像素的尺寸的一半，以避免产生闪点现象，喷淋设备的喷头的孔径可以根据显示屏的像素单元的子像素的尺寸确定。针对65寸4K分辨率显示屏，其像素单元的子像素的尺寸大约为120μm，因而颗粒的尺寸可以控制在60μm以内，申请人通过试验发现，为了制备的玻璃盖板的颗粒的尺寸可以控制在60μm以内，喷淋设备的喷头的孔径可以小于或等于20μm。In order to obtain particles that are evenly distributed and meet the requirements, when frosting the glass substrate in the present application, the frosting powder is firstly sprayed onto the surface of the glass substrate through a spraying device, so as to evenly cover the surface of the glass substrate with a layer of frosting powder. Frosting powder, and then spray the acid liquid on the frosting powder on the surface of the glass substrate through the spray equipment, so that the frosting powder reacts with the acid liquid to generate hydrofluoric acid, and the hydrofluoric acid reacts with the glass substrate to form on the surface of the glass substrate. The evenly distributed particles, that is, particles, can form a certain roughness on the surface of the glass cover, which can scatter the light, so as to achieve the effect of anti-glare. Meanwhile, in order to control the size of the particles to be less than or equal to half the size of the sub-pixels of the pixel unit of the display screen to avoid flash point phenomenon, the aperture of the nozzle of the shower device can be determined according to the size of the sub-pixels of the pixel unit of the display screen. For a 65-inch 4K resolution display screen, the size of the sub-pixels of the pixel unit is about 120 μm, so the size of the particles can be controlled within 60 μm. Within 60 μm, the aperture of the nozzle of the spray equipment can be less than or equal to 20 μm.
在某些实施例中，为了得到更好的蚀刻效果，在对玻璃基板进行蒙砂处理之前可以先对玻璃基板进行水洗和酸洗，以清除玻璃基板表面的灰尘、油脂等杂质。对玻璃基板进行蒙砂处理之后，可以先对玻璃基板进行酸洗和水洗，然后再采用酸对水洗后的玻璃基板进行抛光处理。蒙砂处理后的玻璃基板表面成半透明朦胧状，通过酸对蒙砂处理后的玻璃基板进行抛光处理，可以对玻璃基板进一步反应，以控制最终得到的玻璃盖板的雾度、光泽度、鲜映性等特性。In some embodiments, in order to obtain a better etching effect, the glass substrate may be washed with water and acid before frosting to remove impurities such as dust and grease on the surface of the glass substrate. After the frosting treatment is performed on the glass substrate, the glass substrate may be pickled and washed with water first, and then the water-washed glass substrate may be polished with acid. The surface of the frosted glass substrate is translucent and hazy, and the frosted glass substrate is polished by acid, which can further react to the glass substrate to control the haze, gloss, Features such as sharpness.
在某些实施例中，为了避免抛光处理的过程中将蒙砂处理阶段在玻璃基板表面生成的晶状颗粒被破坏掉，可以采用弱酸对蒙砂处理后的玻璃基板进行抛光处理，比如可以采用氢氟酸对玻璃基板进行抛光处理，同时为了保证抛光处理的效果，可以适当延长抛光处理的时长。In some embodiments, in order to avoid destroying the crystalline particles generated on the surface of the glass substrate during the frosting process during the polishing process, a weak acid may be used to polish the frosted glass substrate, for example, using Hydrofluoric acid is used to polish the glass substrate, and at the same time, in order to ensure the effect of the polishing, the duration of the polishing can be appropriately extended.
当然，在某些实施例中，可以通过对蒙砂处理和抛光处理阶段的工艺进行控制，控制颗粒的算术平均偏差RA，在某些实施例中，RA可以控制在0.2制在左右。Of course, in some embodiments, the arithmetic mean deviation RA of the particles can be controlled by controlling the process of frosting and polishing. In some embodiments, RA can be controlled at about 0.2.
在某些实施例中，蒙砂粉的成分主要为氟化物，氟化物可以是氟化铵、氟化钾以及氟化钙中的一种或多种。In some embodiments, the composition of the frosting powder is mainly fluoride, and the fluoride can be one or more of ammonium fluoride, potassium fluoride and calcium fluoride.
在某些实施例中，为了控制生成的颗粒的尺寸以及分布的均匀度，可以控制蒙砂粉的颗粒直径为30-100nm。In some embodiments, in order to control the size of the generated particles and the uniformity of distribution, the particle diameter of the frosting powder can be controlled to be 30-100 nm.
在某些实施例中，喷洒至覆盖有蒙砂粉的玻璃基板表面的酸液可以是盐酸 或者硫酸中的一种或多种，盐酸或者硫酸的浓度为5％-10％。In some embodiments, the acid solution sprayed on the surface of the glass substrate covered with frosting powder may be one or more of hydrochloric acid or sulfuric acid, and the concentration of hydrochloric acid or sulfuric acid is 5%-10%.
在某些实施例中，如图7所示，玻璃基板可以通过传送设备传输至喷淋设备的喷头的下方位置，以便喷淋设备将蒙沙粉和酸液喷洒至玻璃基板表面，其中，传送设备的传输速率与喷淋设备喷头的喷洒压力对生成的颗粒的尺寸也有影响，比如，传送速率越慢，喷洒至玻璃基板的酸液和蒙砂粉可能越多，反应时间越长，形成的颗粒的尺寸可能越大，而喷淋设备喷洒蒙沙粉和酸液时喷头的压力越大，喷洒至玻璃基板的酸液和蒙砂粉可能越多，形成的颗粒的尺寸也可能越大。所以，为了更好地控制颗粒的尺寸与显示屏像素单元的子像素的尺寸的大小关系，在某些实施例中，喷淋设备喷洒蒙沙粉和酸液时喷头的压力可以设置为5kg-7kg，传送设备的传输速率可以设置为4m/min～6m/min。In some embodiments, as shown in FIG. 7 , the glass substrate can be transported to a position below the spray head of the spraying device through the conveying device, so that the spraying device can spray the frosting powder and the acid solution on the surface of the glass substrate, wherein the conveying device The transmission rate of the equipment and the spray pressure of the sprinkler head of the spray equipment also affect the size of the generated particles. For example, the slower the transmission rate, the more acid and frosting powder may be sprayed on the glass substrate, and the longer the reaction time, the more formed The size of the particles may be larger, and the greater the pressure of the nozzle when the spray equipment sprays frosting powder and acid, the more acid and frosting powder may be sprayed on the glass substrate, and the size of the particles formed may also be larger. Therefore, in order to better control the size relationship between the size of the particles and the size of the sub-pixels of the pixel unit of the display screen, in some embodiments, the pressure of the spray head when the spray device sprays the frosting powder and the acid liquid can be set to 5kg- 7kg, the transmission rate of the conveying equipment can be set to 4m/min ~ 6m/min.
当然，由于玻璃盖板表面的防眩光层比较粗糙，会导致显示屏表面不够顺滑，手感较差，影响用户的体验。同时，空气、水分或其他杂质接触玻璃盖板表面的防眩光层，也易导致玻璃盖板表面脏污，降低用户体验。所以，在某些实施例中，如图8所示，玻璃盖板51还可以包括抗指纹层512，抗指纹层512可以覆盖于防眩光层511之上，由于抗指纹层512具有疏水疏油的特性，可以有效地以杜绝空气、水分或其他杂质污染显示装置表面，同时还可以提高显示装置表面的顺滑度，增强用户的手感。Of course, since the anti-glare layer on the surface of the glass cover plate is relatively rough, the surface of the display screen will not be smooth enough, and the hand feeling will be poor, which will affect the user's experience. At the same time, when air, moisture or other impurities contact the anti-glare layer on the surface of the glass cover, it is also easy to cause the surface of the glass cover to be dirty and reduce the user experience. Therefore, in some embodiments, as shown in FIG. 8 , the glass cover 51 may further include an anti-fingerprint layer 512 , and the anti-fingerprint layer 512 may cover the anti-glare layer 511 , since the anti-fingerprint layer 512 is hydrophobic and oleophobic It can effectively prevent air, moisture or other impurities from contaminating the surface of the display device, and at the same time, it can also improve the smoothness of the surface of the display device and enhance the user's hand feeling.
在某些实施例中，抗指纹层可以通过在防眩光层表面喷涂抗指纹涂层制备得到。在某些实施例中，抗指纹涂层的成分为可以是:氟化物20％～25％、基体树脂：15％～20％、固化剂：1％～3％。包括防眩光层的玻璃基板可以先经过等离子清洗，然后在表面喷涂抗指纹涂层，在某些实施例中，喷枪的压强可以是为5Mpa～7Mpa，流量为10g/30秒～15g/30秒，涂层需要烘烤30min，温度为150度左右，从而在防眩光层上面覆盖抗指纹层。In some embodiments, the anti-fingerprint layer can be prepared by spraying an anti-fingerprint coating on the surface of the anti-glare layer. In some embodiments, the composition of the anti-fingerprint coating may be: 20%-25% of fluoride, base resin: 15%-20%, curing agent: 1%-3%. The glass substrate including the anti-glare layer can be cleaned by plasma first, and then the anti-fingerprint coating is sprayed on the surface. In some embodiments, the pressure of the spray gun can be 5Mpa～7Mpa, and the flow rate can be 10g/30s～15g/30s , the coating needs to be baked for 30 minutes and the temperature is about 150 degrees, so that the anti-fingerprint layer is covered on the anti-glare layer.
此外，为了制备得到颗粒的尺寸符合需求且均匀分布的玻璃盖板，本申请提供了玻璃盖板的制备方法，可以通过喷淋设备将蒙砂粉均匀喷洒至玻璃基板表面，以在玻璃基板表面均匀覆盖蒙砂粉，然后再将酸液喷洒至覆盖有蒙砂粉的玻璃基板上，通过酸与蒙砂粉反应生成氢氟酸，并与玻璃基板反应，在玻璃 基板形成均匀分布的颗粒，其中，可以通过控制喷淋设备喷头的孔径控制颗粒的尺寸，喷淋设备的孔径可以根据显示屏的像素单元的子像素的尺寸确定，以制备颗粒尺寸符合需求的玻璃盖板。In addition, in order to prepare a glass cover plate whose particle size meets the requirements and is uniformly distributed, the present application provides a preparation method of a glass cover plate, which can spray frosting powder evenly on the surface of the glass substrate by spraying equipment, so that the surface of the glass substrate can be evenly sprayed with frosting powder. The frosting powder is evenly covered, and then the acid solution is sprayed onto the glass substrate covered with the frosting powder. The acid reacts with the frosting powder to generate hydrofluoric acid, which reacts with the glass substrate to form uniformly distributed particles on the glass substrate. The size of the particles can be controlled by controlling the aperture of the nozzle of the spray equipment, and the aperture of the spray equipment can be determined according to the size of the sub-pixels of the pixel unit of the display screen, so as to prepare a glass cover plate with a particle size that meets the requirements.

通常，为了在玻璃表面形成一定的粗糙度，会采用化学蚀刻的方式对玻璃基板进行处理，以便在玻璃基板表面形成凹凸不平的轮廓结构。化学蚀刻主要是通过对玻璃基板进行蒙砂处理，蒙砂处理的主要原理是通过酸液与玻璃反应玻璃表面进行化学腐蚀以形成粗糙面，通常对玻璃基板进行腐蚀用到的酸液为氢氟酸，以下为氢氟酸与玻璃反应化学式:Usually, in order to form a certain roughness on the glass surface, the glass substrate is processed by chemical etching, so as to form an uneven profile structure on the surface of the glass substrate. Chemical etching is mainly performed by frosting the glass substrate. The main principle of the frosting treatment is to chemically corrode the glass surface by reacting the acid solution with the glass to form a rough surface. Usually, the acid solution used to corrode the glass substrate is hydrogen fluoride. Acid, the following is the chemical formula of the reaction between hydrofluoric acid and glass:
aNa 2O·bK 2O·cPbO·dCaO·eMgO·fSiO 2+(2a+2b+2c+2d+2e+4f)HF→aNa 2SiF6+bK 2SiF 6+cPbF 2+dCaF 2+eMgF 2+[f-(a+b)]SiF 4+(a+b+c+d+e+2f)H 2O - aNa 2 O·bK 2 O·cPbO·dCaO·eMgO·fSiO 2 +(2a+2b+2c+2d+2e+4f)HF→aNa 2 SiF6+bK 2 SiF 6 +cPbF 2 +dCaF 2 +eMgF 2 + [f-(a+b)]SiF 4 +(a+b+c+d+e+2f)H 2 O -
玻璃的成分主要为硅酸盐，硅酸盐与氢氟酸反应，生成的氟化钙、氟化钡、氟化铅等氢氟酸盐不溶于水。The main component of glass is silicate, which reacts with hydrofluoric acid, and the resulting hydrofluoric acid salts such as calcium fluoride, barium fluoride, and lead fluoride are insoluble in water.

With the prolongation of the reaction time, the reactants accumulate into granular crystals and adhere to the surface of the glass substrate. The surface of the glass substrate with the reactants adhered It hinders the further corrosion of the etchant, and finally forms uneven particles on the surface of the glass substrate, making the glass substrate from a smooth surface to a rough surface, and the rough surface scatters the incident light, which is translucent and has a hazy feeling. , so it is called frosting.
通常，氢氟酸可以通过氟化物与盐酸、硫酸等反应制备得到。所以，在蒙砂处理过程中，相关技术采用直接将玻璃基板浸泡到由氟化物、盐酸或者硫酸等组成的蚀刻液当中，以利用氟化物与盐酸或者硫酸生成的氢氟酸对玻璃基板进行腐蚀，或者将蚀刻液通过喷淋设备喷洒至玻璃基板上，以对玻璃基板进腐蚀，上述方式无法很好地控制在玻璃基板表面生成的颗粒的尺寸、以及颗粒分布的均匀度，往往制备得到的玻璃盖板表面颗粒分布不均匀，且尺寸较大。Generally, hydrofluoric acid can be prepared by reacting fluoride with hydrochloric acid, sulfuric acid, etc. Therefore, in the frosting process, the related art directly immerses the glass substrate in an etching solution composed of fluoride, hydrochloric acid or sulfuric acid, so as to use the hydrofluoric acid generated by fluoride and hydrochloric acid or sulfuric acid to corrode the glass substrate , or spray the etchant on the glass substrate through spray equipment to corrode the glass substrate, the above method cannot well control the size of the particles generated on the surface of the glass substrate and the uniformity of particle distribution, often prepared The particles on the surface of the glass cover plate are unevenly distributed and larger in size.
为了得到均匀分布且尺寸符合需求的颗粒，本申请在对玻璃基板进行蒙砂处理时，先通过喷淋设备将蒙砂粉均匀喷洒至玻璃基板的表面，以在玻璃基板表面均匀的覆盖一层蒙砂粉，然后通过喷淋设备将酸液喷洒至玻璃基板的蒙砂粉上，以便蒙砂粉与酸液反应生成氢氟酸，氢氟酸再与玻璃基板反应，在玻璃基板表面形成均匀分布的颗粒，以在玻璃盖板表面形成一定的粗糙度，对光线可以产生散射作用，从而实现防眩光的效果。同时，为了控制颗粒的尺寸小于或等于显示屏像素单元的子像素的尺寸的一半，以避免产生闪点现象，喷淋设备的喷头的孔径可以根据显示屏的像素单元的子像素的尺寸确定。针对65寸4K分辨率显示屏，其像素单元的子像素的尺寸大约为120μm，因而颗粒的尺寸可以控制在60μm以内，申请人通过试验发现，为了制备的玻璃盖板的颗粒的尺寸可以控制在60μm以内，可以控制喷淋设备的喷头的孔径小于或等于20μm。如图9所示，为本申请一个实施例中制备的玻璃盖板在显微镜下的微观结构示意图，从图中可知，颗粒比较均匀的分布在玻璃盖板表面。In order to obtain particles that are evenly distributed and meet the requirements, when frosting the glass substrate in the present application, the frosting powder is firstly sprayed onto the surface of the glass substrate through a spraying device, so as to evenly cover the surface of the glass substrate with a layer of frosting powder. Frosting powder, and then spray the acid liquid on the frosting powder of the glass substrate through the spray equipment, so that the frosting powder reacts with the acid liquid to generate hydrofluoric acid, and the hydrofluoric acid reacts with the glass substrate to form a uniform on the surface of the glass substrate. The distributed particles can form a certain roughness on the surface of the glass cover, which can scatter the light, so as to achieve the effect of anti-glare. Meanwhile, in order to control the size of the particles to be less than or equal to half the size of the sub-pixels of the pixel unit of the display screen to avoid flash point phenomenon, the aperture of the nozzle of the shower device can be determined according to the size of the sub-pixels of the pixel unit of the display screen. For a 65-inch 4K resolution display screen, the size of the sub-pixels of the pixel unit is about 120 μm, so the size of the particles can be controlled within 60 μm. Within 60μm, the aperture of the nozzle of the spray equipment can be controlled to be less than or equal to 20μm. As shown in FIG. 9 , which is a schematic view of the microscopic structure of the glass cover plate prepared in one embodiment of the application under a microscope, it can be seen from the figure that the particles are relatively uniformly distributed on the surface of the glass cover plate.
在某些实施例中，为了得到更好的蚀刻效果，在对玻璃基板进行蒙砂处理之前可以先对玻璃基板进行水洗和酸洗，以清除玻璃基板表面的灰尘、油脂等杂质。对玻璃基板进行蒙砂处理之后，可以先对玻璃基板进行酸洗和水洗，然后再采用酸对水洗后的玻璃基板进行抛光处理。蒙砂处理后的玻璃基板表面成半透明朦胧状，通过酸对蒙砂处理后的玻璃基板进行抛光处理，可以对玻璃基板进一步反应，以控制最终得到的玻璃盖板的雾度、光泽度、鲜映性等特性。In some embodiments, in order to obtain a better etching effect, the glass substrate may be washed with water and acid before frosting to remove impurities such as dust and grease on the surface of the glass substrate. After the frosting treatment is performed on the glass substrate, the glass substrate may be pickled and washed with water first, and then the water-washed glass substrate may be polished with acid. The surface of the frosted glass substrate is translucent and hazy, and the frosted glass substrate is polished by acid, which can further react to the glass substrate to control the haze, gloss, Features such as sharpness.
在某些实施例中，为了避免抛光处理的过程中将蒙砂处理阶段在玻璃基板表面生成的晶状颗粒被破坏掉，可以采用弱酸对蒙砂处理后的玻璃基板进行抛光处理，比如可以采用氢氟酸对玻璃基板进行抛光处理，同时为了保证抛光处理的效果，可以适当延长抛光处理的时长。In some embodiments, in order to avoid destroying the crystalline particles generated on the surface of the glass substrate during the frosting process during the polishing process, a weak acid may be used to polish the frosted glass substrate, for example, using Hydrofluoric acid is used to polish the glass substrate, and at the same time, in order to ensure the effect of the polishing, the duration of the polishing can be appropriately extended.
当然，在某些实施例中，可以通过对蒙砂处理和抛光处理阶段的工艺进行控制，控制颗粒的算术平均偏差RA，在某些实施例中，RA可以控制在0.2制在左右。Of course, in some embodiments, the arithmetic mean deviation RA of the particles can be controlled by controlling the process of frosting and polishing. In some embodiments, RA can be controlled at about 0.2.
在某些实施例中，蒙砂粉的成分主要为为氟化物，氟化物可以是氟化铵、氟化钾以及氟化钙中的一种后者多种。In some embodiments, the composition of the frosting powder is mainly fluoride, and the fluoride can be one or more of ammonium fluoride, potassium fluoride and calcium fluoride.
在某些实施例中，为了控制生成的颗粒的尺寸以及分布的均匀度，可以控制蒙砂粉的颗粒直径为30-100nm。In some embodiments, in order to control the size of the generated particles and the uniformity of distribution, the particle diameter of the frosting powder can be controlled to be 30-100 nm.
在某些实施例中，喷洒至覆盖有蒙砂粉的玻璃基板表面的酸液可以是盐酸或者硫酸中的一种或多种，盐酸或者硫酸的浓度为5％-10％。In some embodiments, the acid solution sprayed on the surface of the glass substrate covered with frosting powder may be one or more of hydrochloric acid or sulfuric acid, and the concentration of hydrochloric acid or sulfuric acid is 5%-10%.
在某些实施例中，如图7所示，玻璃基板可以通过传送设备传输至喷淋设备的喷头的下方位置，以便喷淋设备将蒙沙粉和酸液喷洒至玻璃基板表面，其中，传送设备的传输速率与喷淋设备喷头的喷洒压力对生成的颗粒的尺寸也有影响，比如，传送速率越慢，喷洒至玻璃基板的酸液和蒙砂粉可能越多，反应时间越长，形成的颗粒的尺寸可能越大，而喷淋设备喷洒蒙沙粉和酸液时喷头的压力为越大，喷洒至玻璃基板的酸液和蒙砂粉可能越多，形成的颗粒的尺寸也可能越大。所以，为了严格控制颗粒的尺寸与显示屏像素单元的子像素的尺寸的大小关系，在某些实施例中，喷淋设备喷洒蒙沙粉和酸液时喷头的压力可以设置为5kg-7kg，传送设备的传输速率可以设置为4m/min～6m/min。In some embodiments, as shown in FIG. 7 , the glass substrate can be transported to a position below the spray head of the spraying device through the conveying device, so that the spraying device can spray the frosting powder and the acid solution on the surface of the glass substrate, wherein the conveying device The transmission rate of the equipment and the spray pressure of the sprinkler head of the spray equipment also affect the size of the generated particles. For example, the slower the transmission rate, the more acid and frosting powder may be sprayed on the glass substrate, and the longer the reaction time, the more formed The size of the particles may be larger, and the greater the pressure of the nozzle when the spray equipment sprays frosting powder and acid solution, the more acid solution and frosting powder may be sprayed on the glass substrate, and the size of the particles formed may also be larger. . Therefore, in order to strictly control the size relationship between the size of the particles and the size of the sub-pixels of the pixel unit of the display screen, in some embodiments, the pressure of the spray head can be set to 5kg-7kg when the spray equipment sprays the frosting powder and the acid liquid, The transmission rate of the conveying equipment can be set to 4m/min～6m/min.
由于玻璃盖板表面的防眩光层比较粗糙，会导致显示装置表面不够顺滑，手感较差，影响用户的体验。同时，空气、水分或其他杂质接触玻璃盖板表面的防眩光层，也易导致玻璃盖板表面脏污，降低用户体验。所以，在某些实施例中，在玻璃盖板形成防眩光层后，还可以通过在防眩光层表面喷涂抗指纹涂层，以在防眩光层表面形成抗指纹层。由于抗指纹层具有疏水疏油的特性，可 以有效地以杜绝空气、水分或其他杂质污染显示装置表面，同时还可以提高显示装置表面的顺滑度，增强用户的手感。Since the anti-glare layer on the surface of the glass cover plate is relatively rough, the surface of the display device is not smooth enough, and the hand feel is poor, which affects the user experience. At the same time, when air, moisture or other impurities contact the anti-glare layer on the surface of the glass cover, it is also easy to cause the surface of the glass cover to be dirty and reduce the user experience. Therefore, in some embodiments, after the anti-glare layer is formed on the glass cover plate, an anti-fingerprint coating may be sprayed on the surface of the anti-glare layer to form an anti-fingerprint layer on the surface of the anti-glare layer. Since the anti-fingerprint layer has hydrophobic and oleophobic properties, it can effectively prevent air, moisture or other impurities from contaminating the surface of the display device, and at the same time, it can also improve the smoothness of the surface of the display device and enhance the user's hand feel.
在某些实施例中，抗指纹涂层的成分为可以是:氟化物20％～25％、基体树脂：15％～20％、固化剂：1％～3％。包括防眩光层的玻璃基板可以先经过等离子清洗，然后在表面喷涂抗指纹涂层，在某些实施例中，喷枪的压强可以是为5Mpa～7Mpa，流量为10g/30秒～15g/30秒，涂层需要烘烤30min，温度为150度左右，从而在防眩光层上面覆盖抗指纹层。In some embodiments, the composition of the anti-fingerprint coating may be: 20%-25% of fluoride, base resin: 15%-20%, curing agent: 1%-3%. The glass substrate including the anti-glare layer can be cleaned by plasma first, and then the anti-fingerprint coating is sprayed on the surface. In some embodiments, the pressure of the spray gun can be 5Mpa～7Mpa, and the flow rate can be 10g/30s～15g/30s , the coating needs to be baked for 30 minutes and the temperature is about 150 degrees, so that the anti-fingerprint layer is covered on the anti-glare layer.
