The terms "first" and "second" are only used for the purpose of description, and should not be understood as indicating or implying relative importance or implying indicating the number of technical features. "Plurality" means two or more, unless expressly specifically limited otherwise.

In order to illustrate the technical solutions provided in the present application, the following detailed description is given in conjunction with the specific drawings and embodiments.

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 first surface 11 . A frosted area 111, and the surface morphology of the first frosted area 111 satisfies: the range of the arithmetic mean deviation of the contour is 0.2 μm~0.45 μm, the range of the average width of the contour unit is 31 μm~60 μm, and the range of the maximum height of the contour is 0.4 μm ~2.5 μm, and the gloss at 60° angle ranges from 10 to 40 SGU.

It should be understood that, with the average height of the first frosted area 111 as the plane where the origin is located, and the direction perpendicular to the first frosted area 111 as the direction of the ordinate, the arithmetic mean deviation of the contour refers to the sampling length, the first frosted area 111 The arithmetic mean of the absolute values of the ordinates of each point on the surface, namely Ra; the average width of the contour element refers to the average value of the width of the contour elements on the surface of the first frosted area 111 within the sampling length, namely Rsm; The maximum height refers to the difference between the maximum point and the minimum point of the ordinate within the sampling length, that is, Rz. The above three parameters collectively reflect the unevenness and roughness of the surface of the first frosted area 111 .

In addition, the unit of gloss SGU should be understood as the Standard Gloss Unit, that is, the standard gloss unit, which is dimensionless and is related to the arithmetic mean deviation of the contour, the average width of the contour unit, the maximum height of the contour, and 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.

Setting within a preset range can make the anti-glare plate 1 have a frosted effect, so as to have a diffuse reflection effect on the light irradiated from the first surface 11 or the second surface 12 to the first frosted area 111, and can disperse and pass through the anti-glare plate 111. The light of the glare plate 1 has a visual effect close to the diffuse reflection, thereby reducing or avoiding the glare effect and the flash point effect; moreover, by configuring the first frosted area 111 according to the preset parameters, it can also make the first frosted area 111 . The visual effect is similar to that of paper, which conforms to the general viewing habits of the human eye, further reducing the visual fatigue of the user after viewing the anti-glare plate 1 for a long time, making it especially suitable for screens or covers of various electronic terminals.

If the average width of the contour units is too small, the frosting effect is not obvious, which affects the ability of the first frosted area 111 to eliminate the glare effect. normal display. Under the preset arithmetic mean deviation of the contour, the average width of the contour unit and the maximum height of the contour, the gloss at a 60° angle should be controlled within the range of 10~40SGU to ensure that the anti-diffusion plate has appropriate haze and light transmission Spend. Moreover, any one of the arithmetic mean deviation of the contour, the average width of the contour unit, the maximum height of the contour, and the glossiness exceeds the preset numerical range, which will affect the paper-like effect of the anti-glare sheet 1 provided in this embodiment.

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 .

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.

As a specific solution of this embodiment, for the solution of disposing the second frosted area 121 on the second surface 12, the surface morphology of the second frosted area 121 is formed by the same frosting etching method.

1 and 2, in an embodiment of the present application, the first surface 11 further includes a first lighting area 112, and the second surface 12 further includes a second lighting area 122 opposite to the first lighting area 112, Both the first lighting area 112 and the second lighting area 122 are polished surfaces.

The significance of arranging the first lighting area 112 and the second lighting area 122 with flat surface topography is that the light will not be scattered after passing through the first lighting area 112 and the second lighting area 122, and the image can still be imaged. In this way, arranging the front camera opposite to the first lighting area 112 or the second lighting area 122 can prevent the diffuse reflection effect of the first frosted area 111 or the second frosted area 121 from affecting the normal lighting of the camera.
