请参阅图1、图2和图4，本申请的一个实施例提供了一种防眩光板1，防眩光板1具有相对设置的第一面11和第二面12，第一面11包括具有防眩光功能的第一磨砂区域111，且第一磨砂区域111由多个微观凹球面101拼接形成，各微观凹球面101满足：各微观凹球面101的宽度范围为2μm~25μm，各微观凹球面101的深度范围为0.2μm~2.5μm。以第一磨砂区域111的平均高度为原点所在平面，以垂直于第一面11的方向为纵坐标所在的方向，微观凹球面101的宽度指的是随机取样的若干微观凹球面101中，将各微观凹球面101近似为球冠面后，球冠面最大开口部分圆的直径的平均值；微观凹球面101的深度指的是随机取样的若干微观凹球面101中，各微观内球面101的深度的平均值。微观凹球面101的宽度和深度，均属于第一磨砂区域111表面的不平整度与粗糙度的决定因素。Referring to FIG. 1 , FIG. 2 and FIG. 4 , an embodiment of the present application provides an anti-glare plate 1 . The anti-glare plate 1 has a first surface 11 and a second surface 12 arranged opposite to each other, and the first surface 11 includes a The first frosted area 111 with anti-glare function, and the first frosted area 111 is formed by splicing a plurality of microscopic concave spherical surfaces 101, and each microscopic concave spherical surface 101 satisfies: the width of each microscopic concave spherical surface 101 ranges from 2 μm to 25 μm, and each microscopic concave spherical surface The depth of 101 ranges from 0.2 μm to 2.5 μm. Taking the average height of the first frosted area 111 as the plane of the origin, and taking the direction perpendicular to the first surface 11 as the direction of the ordinate, the width of the microscopic concave spherical surface 101 refers to the random sampling of several microscopic concave spherical surfaces 101, the After each microscopic concave spherical surface 101 is approximated as a spherical cap surface, the average value of the diameter of the circle with the largest opening of the spherical cap surface; Average value of depth. The width and depth of the microscopic concave spherical surface 101 both belong to the determining factors of the unevenness and roughness of the surface of the first frosted area 111 .
实施本实施例提供的防眩光板1，至少具有以下有益技术效果：Implementing the anti-glare plate 1 provided in this embodiment has at least the following beneficial technical effects:
本实施例提供的防眩光板1，通过在其第一面11设置多个凹陷的微观凹球面101组成的第一磨砂区域111，并将各微观凹球面101的宽度和深度设置在预设范围内，能够使得防眩光板1具有适中的磨砂效果，从而在不影响人眼透过防眩光板1观看屏幕的基础上，更高效地打散从第一面11或者第二面12照射到第一磨砂区域111的光线，进而具有更好的漫反射能力，起到接近于纸张的视觉效果，很大程度上减少、甚至完全消除眩光效应和闪点效应；而且，通过按照预设参数配置第一磨砂区域111，还能够使得第一磨砂区域111的视觉效果和纸张类似，符合一般情况下人眼的观看习惯，进一步减少了用户长时间目视防眩光板1后的视觉疲劳，使之尤其适用于各类电子终端的屏幕或者盖板；此外，本实施例提供的防眩光板1，虽然其表面具有多个微观凹球面101，但是没有对防眩光板1的结构强度产生明显负面效应。In the anti-glare plate 1 provided in this embodiment, a first frosted area 111 composed of a plurality of concave micro concave spherical surfaces 101 is provided on the first surface 11 thereof, and the width and depth of each micro concave spherical surface 101 are set within a preset range It can make the anti-glare plate 1 have a moderate frosted effect, so as not to affect the human eye viewing the screen through the anti-glare plate 1, it can more efficiently disperse the radiation from the first surface 11 or the second surface 12 to the first surface 12. The light in the frosted area 111 has better diffuse reflection ability, and has a visual effect close to that of paper, which greatly reduces or even completely eliminates the glare effect and flash point effect; A frosted area 111 can also make the visual effect of the first frosted area 111 similar to that of paper, which conforms to the viewing habits of the human eye in general, and further reduces the visual fatigue of the user after viewing the anti-glare plate 1 for a long time, making it especially Applicable to screens or cover plates of various electronic terminals; in addition, the anti-glare plate 1 provided in this embodiment has no obvious negative effect on the structural strength of the anti-glare plate 1 although its surface has a plurality of microscopic concave spherical surfaces 101 .
需要说明的是，闪点效应指的是一个像素点发出的光线经过第一磨砂区域111时，在第一磨砂区域111的表面发生折射，不同位置折射的光线之间发生干涉，进而在人眼观看时产生彩点或者明暗点的效应。本实施例提供的防眩光板1，参数配置合理，微观凹球面101具有足够小的宽度，能够很大程度上减少、甚至完全消除闪点效应。It should be noted that the flash point effect refers to the fact that when the light emitted by a pixel passes through the first frosted area 111 , the surface of the first frosted area 111 is refracted, and the light refracted at different positions interferes with each other, which in turn affects the human eye. The effect of colored dots or light and dark dots is produced when viewing. The anti-glare plate 1 provided in this embodiment has reasonable parameter configuration, and the microscopic concave spherical surface 101 has a sufficiently small width, which can greatly reduce or even completely eliminate the flash point effect.
还应说明的是，微观凹球面101的宽度过小，则容易导致磨砂效果不明显，影响第一磨砂区域111对眩光效应的消除能力；微观凹球面101的宽度过大，则容易导致第一磨砂区域111过于粗糙且毛刺感强，影响防眩光板1给予用户的视觉体验和触觉体验。微观凹球面101的深度过大则意味着微观凹陷的深度过浅，容易导致磨砂效果不明显，影响第一磨砂区域111对眩光效应的消除能力；微观凹球面101的深度过小，则容易导致第一磨砂区域111过于粗糙且毛刺感强，影响防眩光板1给予用户的视觉体验和触觉体验。微观凹球面101的宽度和深度的任意一个超出预设数值范围，均会影响本实施例提供的防眩光板1的类纸效果。It should also be noted that if the width of the microscopic concave spherical surface 101 is too small, the frosting effect is likely to be insignificant, which affects the ability of the first frosted area 111 to eliminate the glare effect; if the width of the microscopic concave spherical surface 101 is too large, the first The frosted area 111 is too rough and has a strong burr feeling, which affects the visual experience and tactile experience given by the anti-glare plate 1 to the user. If the depth of the microscopic concave spherical surface 101 is too large, it means that the depth of the microscopic concave surface 101 is too shallow, which may easily lead to insignificant frosting effect and affect the ability of the first frosted area 111 to eliminate the glare effect; if the depth of the microscopic concave spherical surface 101 is too small, it is easy to cause The first frosted area 111 is too rough and has a strong burr feeling, which affects the visual experience and tactile experience given by the anti-glare plate 1 to the user. Any of the width and depth of the microscopic concave spherical surface 101 exceeding the preset value range will affect the paper-like effect of the anti-glare plate 1 provided in this embodiment.
请参阅图4至图7，微观凹球面101是密集地排布在第一磨砂区域111的表面的，微观凹球面101均为凹陷球面，相邻的微观凹球面101的连接处形成若干长条形的鞍形面102，鞍形面102的两端形成有顶点103。此时，顶点103与微观凹球面101的最低点之间的高度差，即为微观凹球面101的深度，其算术值即为微观凹球面101的深度；将鞍形面102围合形成的各微观凹球面101等效为球冠面，球冠面的最大开口部分圆的直径即为微观凹球面101的宽度，其算术值即为微观凹球面的宽度。从微观凹球面101的不同位置照射到第一磨砂区域111的光线，会被反射或者折射至不同的方向，进而将光线打散，起到消除眩光的效果；进一步的，微观凹球面101的尺寸在微米级别，小于采用本实施例提供的防眩光板1的显示器的像素点的尺寸，同一像素点发出的光线不会在从第一磨砂面111的不同位置折射后发生干涉，在消除眩光的同时，还能够消除防眩光板的闪点效应。Please refer to FIGS. 4 to 7 , the microscopic concave spherical surfaces 101 are densely arranged on the surface of the first frosted area 111 , the microscopic concave spherical surfaces 101 are all concave spherical surfaces, and several long strips are formed at the joints of the adjacent microscopic concave spherical surfaces 101 . A saddle-shaped surface 102 is formed with vertices 103 at both ends of the saddle-shaped surface 102 . At this time, the height difference between the vertex 103 and the lowest point of the microscopic concave spherical surface 101 is the depth of the microscopic concave spherical surface 101, and its arithmetic value is the depth of the microscopic concave spherical surface 101; The microscopic concave spherical surface 101 is equivalent to a spherical cap surface, the diameter of the largest opening part circle of the spherical cap surface is the width of the microscopic concave spherical surface 101 , and its arithmetic value is the width of the microscopic concave spherical surface. The light irradiated to the first frosted area 111 from different positions of the microscopic concave spherical surface 101 will be reflected or refracted to different directions, thereby scattering the light to eliminate glare; further, the size of the microscopic concave spherical surface 101 At the micron level, it is smaller than the pixel size of the display using the anti-glare plate 1 provided in this embodiment, and the light emitted by the same pixel will not interfere after being refracted from different positions of the first frosted surface 111 . At the same time, it can also eliminate the flash point effect of the anti-glare board.
作为本实施例的一个优选方案，第一磨砂区域111在60°角下的光泽度的范围为10~40SGU。光泽度的单位SGU应当被理解为Standrad Gloss Unit，也即标准光泽度单位，该单位无量纲，与微观凹球面101的宽度、深度，以及材料本身的性质有关。第一磨砂区域111的光泽度能够反映第一磨砂区域111表面的微观平整度。可选的，防眩光板1采用钢化玻璃制成，或者，防眩光板1采用聚甲基丙烯酸甲酯（Polymethyl Methacrylate，PMMA）制成，或者，防眩光板1采用聚碳酸酯（Polycarbonate，PC）制成。As a preferred solution of this embodiment, the glossiness of the first frosted area 111 at an angle of 60° ranges from 10 to 40 SGU. The unit of gloss SGU should be understood as the Standrad Gloss Unit, that is, the standard gloss unit, which has no dimension and is related to the width and depth of the microscopic concave spherical surface 101, as well as the properties of the material itself. The gloss of the first frosted area 111 can reflect the microscopic flatness of the surface of the first frosted area 111 . Optionally, the anti-glare plate 1 is made of tempered glass, or the anti-glare plate 1 is made of polymethyl methacrylate (Polymethyl Methacrylate, PMMA), or the anti-glare plate 1 is made of polycarbonate (Polycarbonate, PC )production.

在本申请的一个实施例中，各微观凹球面满足：各微观凹球面的深度范围为0.5μm~1.9μm。In an embodiment of the present application, each microscopic concave spherical surface satisfies: the depth range of each microscopic concave spherical surface is 0.5 μm˜1.9 μm.
在本申请的一个实施例中，各微观凹球面满足：各微观凹球面的深度范围为0.7μm~1.4μm。In an embodiment of the present application, each microscopic concave spherical surface satisfies that the depth of each microscopic concave spherical surface ranges from 0.7 μm to 1.4 μm.
在本申请的一个实施例中，各微观凹球面满足：各微观凹球面的深度范围为0.8μm~1.2μm。In an embodiment of the present application, each microscopic concave spherical surface satisfies: the depth range of each microscopic concave spherical surface is 0.8 μm˜1.2 μm.
在本申请的一个实施例中，防眩光板1满足：第一磨砂面111的雾度的范围为10%~60%。In an embodiment of the present application, the anti-glare plate 1 satisfies that the haze of the first frosted surface 111 ranges from 10% to 60%.
在本申请的一个实施例中，防眩光板1满足：第一磨砂面111的雾度的范围为20%~50%。In an embodiment of the present application, the anti-glare plate 1 satisfies that the haze of the first frosted surface 111 ranges from 20% to 50%.
在本申请的一个实施例中，防眩光板1满足：第一磨砂面111的雾度的范围为30%~40%。In an embodiment of the present application, the anti-glare plate 1 satisfies that the haze of the first frosted surface 111 ranges from 30% to 40%.
上述各实施例提供的防眩光板1，通过限缩微观凹球面101的宽度和深度的数值范围，并进一步限缩第一磨砂面111的雾度的范围，能够获得具有更优的防眩光效果、防闪点效果和类纸效果的防眩光板1。实际验证的结果表明，按照上述实施例提供的数值范围制造的防眩光板1，能够更好地消除眩光效应和闪点效应，而且，防眩光板1具有更类似于纸张的视觉效果，能够有效减少用户长时间使用电子设备后的视觉疲劳。The anti-glare sheet 1 provided by the above embodiments can obtain a better anti-glare effect by narrowing the numerical range of the width and depth of the microscopic concave spherical surface 101 and further narrowing the range of the haze of the first frosted surface 111 , Anti-flash point effect and anti-glare board with paper-like effect1. The actual verification results show that the anti-glare plate 1 manufactured according to the numerical range provided by the above-mentioned embodiment can better eliminate the glare effect and the flash point effect, and the anti-glare plate 1 has a visual effect more similar to that of paper, and can effectively Reduce the visual fatigue of users after using electronic devices for a long time.
应当理解，本申请各实施例所述的微观凹球面101的深度范围和宽度范围，均指的是第一磨砂面111上的绝大多数的微观凹球面101的深度范围和宽度范围。这是因为，在第一磨砂面111上的微观凹球面101的形成往往是通过宏观方法实现的，这也就意味着存在宽度和深度落在上述范围以外的微观凹球面是必然事件。比如在一些玻璃表面的非晶组织较为松散的区域的微观凹球面101，其深度和宽度往往是大于上述深度和宽度范围的；比如第一磨砂面111的边界处的微观凹球面101，其深度和宽度有时是小于上述宽度和深度范围的。由于上述原因，本申请各实施例所述的微观凹球面101的深度范围和宽度范围，均能够被理解为，只要超过预设比例的微观凹球面101的宽度和深度落在上述范围中，即可称之为微观凹球面101的深度和宽度范围分别处于上述深度和宽度范围内。根据对工艺水平的要求不同，上述的预设比例可以是88%、90%、93%、95%，以及98%中的一个。当然，从统计的角度来看，也可以认为上述范围指的是微观凹球面的平均深度范围和平均深度范围。It should be understood that the depth range and width range of the microscopic concave spherical surface 101 described in each embodiment of the present application refer to the depth range and width range of most of the microscopic concave spherical surface 101 on the first frosted surface 111 . This is because the formation of the microscopic concave spherical surface 101 on the first frosted surface 111 is usually realized by a macroscopic method, which means that the existence of a microscopic concave spherical surface whose width and depth fall outside the above ranges is an inevitable event. For example, the depth and width of the microscopic concave spherical surface 101 in the areas where the amorphous structure is relatively loose on some glass surfaces are often larger than the above-mentioned ranges of depth and width; for example, the microscopic concave spherical surface 101 at the boundary of the first frosted surface 111, its depth and widths are sometimes smaller than the aforementioned width and depth ranges. For the above reasons, the depth range and width range of the microscopic concave spherical surface 101 described in the various embodiments of the present application can be understood as, as long as the width and depth of the microscopic concave spherical surface 101 exceeding the preset ratio fall within the above ranges, that is, The depth and width ranges that can be referred to as the microscopic concave spherical surface 101 are within the aforementioned depth and width ranges, respectively. According to different requirements on the craft level, the above-mentioned preset ratio can be one of 88%, 90%, 93%, 95%, and 98%. Of course, from a statistical point of view, it can also be considered that the above range refers to the average depth range and the average depth range of the microscopic concave spherical surface.
请参阅图2，在本申请的一个实施例中，第二面12包括第二磨砂区域121。Referring to FIG. 2 , in one embodiment of the present application, the second surface 12 includes a second frosted area 121 .
在相对的第一面11和第二面12上分别设置第一磨砂区域111和第二磨砂区域121，这样，对于依次经过第一磨砂区域111和第二磨砂区域121的光线，防眩光板1能够起到更加优秀的漫反射效果和防眩光功能；而且，光线在经过第一磨砂区域111和第二磨砂区域121中与发光面相对的一面时，即使在这一表面发生干涉，另一表面也能够再次打散光线，进而能够明显地削弱闪点效应，并且具备更好的类纸视觉效果。A first frosted area 111 and a second frosted area 121 are respectively provided on the opposite first surface 11 and the second surface 12, so that for the light passing through the first frosted area 111 and the second frosted area 121 in sequence, the anti-glare plate 1 It can play a more excellent diffuse reflection effect and anti-glare function; moreover, when the light passes through the first frosted area 111 and the second frosted area 121 opposite to the light-emitting surface, even if interference occurs on this surface, the other surface It can also disperse the light again, which can significantly weaken the flash point effect and have a better paper-like visual effect.
请参阅图2，在本申请的一个实施例中，第二磨砂区域121的表面形貌满足的条件与第一磨砂区域111的表面形貌满足的条件相同。Referring to FIG. 2 , in an embodiment of the present application, the conditions satisfied by the surface morphology of the second frosted area 121 are the same as those satisfied by the surface morphology of the first frosted area 111 .
第二磨砂区域121采用与第一磨砂区域111相同的表面形貌参数，能够简化防眩光板1的制造工艺。举例而言，如果第一磨砂区域111和第二磨砂区域121是通过蒙砂蚀刻的方法形成的，只需要将第一磨砂区域111和第二磨砂区域121同时浸入在蒙砂蚀刻液，并同时取出即可，无需再分别完成第一磨砂区域111和第二磨砂区域121的成型。而且，在将防眩光板1安装于终端设备或者灯具时，由于第一磨砂区域111和第二磨砂区域121具有相同的表面形貌，无需分辨第一面11和第二面12，起到防错功能。The second frosted area 121 adopts the same surface topography parameters as the first frosted area 111 , which can simplify the manufacturing process of the anti-glare sheet 1 . For example, if the first frosted area 111 and the second frosted area 121 are formed by frosting etching, it is only necessary to immerse the first frosted area 111 and the second frosted area 121 in the frosting etching solution at the same time, and at the same time It can be taken out, and there is no need to separately complete the forming of the first frosted area 111 and the second frosted area 121 . Moreover, when the anti-glare plate 1 is installed on a terminal device or a lamp, since the first frosted area 111 and the second frosted area 121 have the same surface topography, it is not necessary to distinguish the first surface 11 and the second surface 12, which can prevent wrong function.
在本申请的一个实施例中，第一磨砂区域111的表面形貌采用蒙砂蚀刻的方法形成。In an embodiment of the present application, the surface topography of the first frosted region 111 is formed by a frosted etching method.
