The cover plate 100 provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1 and 2, a cover plate 100 according to an embodiment of the present invention includes a substrate 10, an optical texture layer 20, and a coating layer 30.
Specifically, the optical texture layer 20 is disposed on a first side of the substrate 10, a first side surface of the optical texture layer 20 is connected to the substrate 10, a second side surface of the optical texture layer 20 is provided with a plurality of open grooves 21 spaced apart along a first direction, each open groove 21 has a first gradually changing surface 211 and a second gradually changing surface 212, the first gradually changing surface 211 is disposed obliquely with respect to the first side surface, and an inclination angle of the plurality of first gradually changing surfaces 211 gradually increases or gradually decreases in the first direction. The coating layer 30 is connected to the second side of the optical texture layer 20, a projection of the coating layer 30 on the optical texture layer 20 covers the second side, and the coating layer 30 cooperates with the first gradually changing surface 211 and the second gradually changing surface 212 of the plurality of open slots 21 to make the surface of the cover plate 100 gradually change in color.
In other words, the cover 100 according to the embodiment of the present invention may be a mobile phone cover, a battery cover, or other types of plate structures. Referring to fig. 1 and 2, the cover plate 100 of the present invention is mainly composed of a substrate 10, an optical texture layer 20, and a coating layer 30. The optical texture layer 20 may be disposed on a first side of the substrate 10, a first side surface of the optical texture layer 20 is compositely connected with the substrate 10, a second side surface of the optical texture layer 20 is disposed with a plurality of open grooves 21, and the plurality of open grooves 21 may be distributed at intervals along a first direction. Each open groove 21 has a first gradually changing surface 211 and a second gradually changing surface 212, respectively, wherein the first gradually changing surface 211 may be disposed obliquely with respect to the first side surface of the optical texture layer 20. And in the first direction, the inclination angles of the plurality of first gradually-changing surfaces 211 may be designed to gradually increase or gradually decrease, ensuring that the optical texture layer 20 may form a surface shape having a texture effect (see fig. 2 and 4).
A coating 30 is disposed on the second side of the optical texture layer 20, and a projection of the coating 30 onto the optical texture layer 20 may cover the second side of the optical texture layer 20. The coating layer 30 cooperates with the first gradually changing surface 211 and the second gradually changing surface 212 of the plurality of open grooves 21 to form a gradual change, so that the surface of the cover plate 100 presents a gradual change in color. When light is incident from the coating 30, the light may be reflected on the upper and lower surfaces of the coating 30 through the texture structure, and an optical path difference may be formed. From this, the light that makes on penetrating into coating film layer 30 produces the gradual change, presents the gradual change effect of color on the first direction, for example from the gradual change color of a left side to the right side, and simple generous and rich in change guarantees that apron 100 has agility change and fashion and feels, effectively promotes product competitiveness.
In the present application, the coating layer 30 may be a single-color optical dielectric film or a mixed-color optical dielectric film. Monochromatic optical media films or hybrid optical media films are inexpensive, but generally cannot achieve color gradation. For example, in the prior art, a dark gray single-color optical medium film is compounded on a mobile phone cover, and only a single dark gray color without change can be presented. The invention compounds the monochromatic optical medium film on the optical texture layer 20, so that the monochromatic optical medium film can also obtain the texture effect of natural gradual change and transparent texture. Meanwhile, the gradient color band can be changed by the change of the light source, and the atmospheric and variable color effect is presented. Therefore, the cost can be effectively controlled through reasonable color matching design on the premise of showing fashionable and high-quality appearance, and the competitiveness of products is improved.
It should be noted that the visible light range visible to the naked human eye is approximately 380nm to 780 nm. Wherein the standard value is: purple 420nm, blue 470nm, cyan 500nm, green 550nm, yellow 580nm, orange 620nm and red 700 nm.
The principle of optical coating is that, referring to fig. 5, incident light is reflected on both the upper and lower surfaces of the coating layer 30, so that when two beams meet, the optical path difference is n02d, wherein n0Is the refractive index of the coating layer 3030, d is the thickness of the coating layer 3030, when n0When λ is wavelength and N is a natural number, i.e. the optical path difference between two light beams is odd half wavelengths, the two light beams will cancel each other, and then we can only see the complementary color.
When the coating layer 30 is combined on the optical texture layer 20, as shown in fig. 6, the angle of the optical texture layer 20 has an influence on the color of the coating layer 30. In this case, the formula n can be expressed0Where 2d cos θ is (N +1/2) λ, the θ angle of the optical texture 2020 determines the color we see the coating 3030, and the larger the θ angle, the shorter the color shifts.
In the cover plate 100 according to the embodiment of the present invention, the plurality of open grooves 21 may be distributed at intervals along the first direction, the first gradually-changing surface 211 of each open groove 21 may be disposed to be inclined with respect to the first side surface of the optical texture layer 20, and in the first direction, the inclination angles of the plurality of first gradually-changing surfaces 211 may be designed to be gradually increased or gradually decreased, so as to ensure that the optical texture layer 20 may form a surface shape with a texture effect. Taking the inclination angles of the plurality of first gradually-changing surfaces 211 gradually decreasing in the first direction as an example, the cover 100 has a left-right gradually-changing effect from left to right, and the surface shape of the optical texture layer 20 is a low surface shape while being high, and a shallow surface shape while being deep. According to the principle of the fresnel lens, referring to fig. 7 to 9, after we perform lateral separation and longitudinal corresponding separation on the lens, the fresnel lens can be changed on a thin plane by a function of the arrangement of the included angles of the texture V-grooves, so as to generate a stereoscopic depth-of-field effect. The Fresnel lens principle can be used as the theoretical basis of the application, the field depth effect of the left and right gradual change is designed, the product competitiveness is improved, and meanwhile the cost can be effectively controlled.
Therefore, according to the cover plate 100 of the embodiment of the invention, the optical texture layer 20 having the plurality of open grooves 21 is disposed on the base material 10, the inclination angle of the first gradient surface 211 of each open groove 21 is designed to be gradually increased or decreased in the first direction, and the plated film layer 30 is combined with the optical texture layer 20, so that the cover plate 100 presents a gradual change effect of a gradual color change from left to right. The coating layer 30 can adopt a monochromatic optical dielectric film, the monochromatic optical dielectric film is compounded with the optical texture layer 20, the texture effect that the color is naturally gradually changed from left to right and the texture is transparent can be achieved, the product competitiveness is improved, and meanwhile the cost can be effectively controlled.
According to an embodiment of the present invention, the open groove 21 is a V-shaped groove, one sidewall of the open groove 21 is a first tapered surface 211, and the other sidewall of the open groove 21 is a second tapered surface 212.

In some embodiments of the present invention, in two adjacent open slots 21, the first gradually-changing surface 211 of one open slot 21 and the second gradually-changing surface 212 of the other open slot 21 cooperate to form insections, and the insections have equal thicknesses.
In other words, referring to fig. 2 and 4, in two adjacent open grooves 21, the first gradually-changing surface 211 of one open groove 21 and the second gradually-changing surface 212 of the other open groove 21 can cooperate to form insections, so as to ensure the texture of the optical texture layer 20. The thickness H of the plurality of insections is equal and, optionally, the thickness of each insection remains substantially constant at 9.6 μm. In the present application, the first direction may be understood as a horizontal direction from left to right in fig. 2, and an included angle θ between the first gradually-changing surface 211 of each opening groove 21 and a horizontal line of the first direction1May be tapered in the first direction, optionally with an included angle θ1Decreases from left to right, and θ1Approximately from 40 to 10. The included angle theta between the second gradually-changing surface 212 of each open slot 21 and the vertical direction2Also gradually decreases in the first direction.
In the present application, a triangular unit structure may be formed between the insections and the horizontal plane, and as shown in fig. 3, the first and second gradually-changing surfaces 211 and 212 of the unit structure are both inclined surfaces. In the Fresnel lens principle, the first gradually-changing surface 211 is in contact withAngle theta between horizontal lines of the first direction1The angle between the second gradually-changing surface 212 and the vertical direction can be regarded as the included angle theta of the lens unit2L is the lens unit length and H is the lens unit width. In the optical texture layer 20, the first graded surface 211 may serve as a main light reflecting surface, which may also be referred to as a working surface. The light is reflected on the second graded surface 212. The visual angle is small, and the second gradually-changing surface 212 mainly functions as a die drawing surface, so that the die can fall off conveniently.
According to an embodiment of the present invention, the distance between the apexes of the included angles of any two adjacent open grooves 21 is gradually increased in the first direction, and the distance between the apexes of the included angles of two adjacent open grooves 21 is 10 μm to 60 μm.
That is, the distance between the apexes of the included angles β of any two adjacent open grooves 21 may gradually increase in the first direction (the direction from left to right in fig. 2). . The distance L between the vertexes of the included angles of the two adjacent open grooves 21 is 10-60 μm. Alternatively, the distance L increases from left to right, varying approximately from a left end distance L of 17 μm to a rightmost end distance L of 56 μm. The optical texture layer 20 having a good texture is processed by controlling the cutter 40 to step at a gradually increasing distance (see fig. 4).

Wherein the first titanium layer and the second titanium layer are deposited with a titanium dioxide thickness of about 168.2nm, respectively, and the silicon dioxide layer is deposited with a silicon dioxide thickness of about 143.3nm, respectively.

Specifically, in the method for manufacturing the cover plate 100 of the present invention, first, as shown in fig. 10, a sample having an open groove 21 may be manufactured on a mold.
