Description

Anti-glare board and display device

The model relates to the field of display technology, in particular to an anti-glare board.

Usually, in order to protect the display module, a glass cover is installed on the surface of the display panel. However, in the case of strong light, the glass cover will reflect the light and cause glare, which not only reduces the display effect of the display module, but also causes Visual discomfort and strong glare can damage eyesight and even cause blindness. In order to solve the above-mentioned problems, chemical etching methods on the glass cover plate or covering a layer of anti-glare film on the cover plate are currently used to achieve the anti-glare effect of the glass cover plate. However, the chemical etching method is costly and is not environmentally friendly. The anti-glare film is not easy to operate.

In view of the above situation, it is necessary to provide an anti-glare board to solve the above problems.

An anti-glare board, the anti-glare board includes a substrate and a cover layer, the substrate includes a first surface with a microstructure, the first surface has a maximum profile height Rz ranging from 1 μm to 150 μm, and the cover layer Covered on the first surface.

Further, the thickness of the covering layer is 50 μm to 100 μm.

Further, the shape of the microstructure of the first surface includes a pyramid shape, a sine wave shape, a square wave shape, and a sawtooth shape.

Further, the microstructures on the first surface are periodically arranged in a straight line direction.

Further, the material of the substrate is polycarbonate.

Further, the material of the covering layer is polymethyl methacrylate.

A display device includes the above-mentioned anti-glare board.

Compared with the prior art, the anti-glare board of the present invention has a simple structure, easy-to-operate processing method, high production efficiency, low cost, and no pollution.

The drawings show the embodiments of the present invention. The present invention can be implemented in a variety of different forms, and should not be interpreted as being limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more comprehensive and complete, and to enable those skilled in the art to fully understand the scope of the present invention.

Please refer to FIG. 1, the present invention provides an anti-glare board 100. The anti-glare board 100 includes a substrate 10 and a cover layer 20. The substrate 10 includes a first surface 11 with a microstructure, so it has a certain degree of roughness and haze. The covering layer 20 covers the first surface 11 and can further adjust the roughness, haze and gloss.

The substrate 10 includes a first surface 11 and a second surface 12. The first surface 11 is a rough surface with a microstructure. The second surface 12 is a flat surface. The material of the substrate 10 is polycarbonate (PC). In this embodiment, when the substrate 10 is formed, the temperature of the polycarbonate material is controlled to be extruded from the extrusion equipment at 260 to 270 degrees Celsius, and the roller is used for extrusion. The surface of the roller used to extrude polycarbonate material to form the first surface 11 has a microstructure, and the surface of the roller used to extrude polycarbonate material to form the second surface 12 is flat.

The microstructure of the first surface 11 takes the circumference of the roller as a period, that is, the microstructures of the first surface 11 are arranged in a period of the circumference of the roller in the rolling direction of the roller.

The shape of the microstructure of the roller surface forming the first surface 11 may include, but is not limited to, pyramid, wave (for example, sine wave, square wave, triangle wave), or sawtooth. The shape of the microstructure of the first surface 11 may include but It is not limited to the sine wave as shown in FIG. 1, the sawtooth, pyramid, and square waves as shown in FIG.

As shown in FIG. 3, since the first surface 11 has a microstructure, the reflection of light on the first surface 11 is diffuse reflection rather than specular reflection. In other words, the light is reflected at many angles, not just one angle, so as to achieve the anti-glare effect. The range of the maximum height Rz of the contour of the roller surface forming the first surface 11 is 1 μm to 150 μm, and the range of the maximum height Rz of the contour of the first surface 11 is 1 μm to 150 μm. The maximum height of the contour Rz is the distance between the top line of the contour and the bottom line of the valley. The larger the maximum height Rz of the contour of the first surface 11 is, the larger the haze value of the first surface 11 is. For example, the maximum profile height Rz1 of the first surface 11 shown in FIG. 1 is less than the profile maximum height Rz2 of the first surface 11 shown in FIG. 1, and the haze value of the first surface 11 shown in FIG. 1 is less than that shown in FIG. The haze value of the first surface 11. In this embodiment, the haze value may be 5 to 90.

The material of the covering layer 20 is polymethyl methacrylate (PMMA). In this embodiment, when the covering layer 20 is formed, the covering layer 20 of 230 to 250° C. is uniformly coated on the substrate 10 whose temperature drops to 160 to 200 degrees Celsius, and the covering layer 20 is cooled and solidified by cooling. In this embodiment, the thickness of the cover layer 20 is 50 μm to 100 μm, but it is not limited thereto. Covering layers 20 of different thicknesses further change the roughness, haze and gloss of the first surface 11 of the substrate 10. Specifically, the greater the thickness of the cover layer 20, the greater the glossiness. In addition, due to the high mechanical strength and wear resistance of PMMA, it can protect the substrate 10 to a certain extent.

The present invention also provides a display device, which includes a display module and the anti-glare board 100 described above. The anti-glare board 100 can cover the display module. The display device includes, but is not limited to, a display, an automobile instrument display panel, and the like.

Compared with the prior art, the anti-glare board 100 of the present invention has a simple structure, easy-to-operate processing method, high production efficiency, low cost, and no pollution.

The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. The up, down, left and right directions appearing in the figure are only for ease of understanding. Although the present invention has been described in detail with reference to the preferred embodiments, those in the art A person of ordinary skill should understand that the technical solution of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present invention.
