Description

Technical Field

[0001] The utility model belongs to the field of anti-peeping, relates to the composition technology of anti-peeping films, and specifically is an anti-peeping structure. Background Art

[0002] The anti-peeping film, through its special structural design, makes the information on the screen only clearly visible within a certain angle range from the front, while it appears dark or blurry when viewed from the side, thus achieving an anti-peeping effect and preventing people next to you from peeping at the screen content, thereby ensuring the safety of personal privacy.

[0003] The main structure of the anti-privacy film consists of two parts: the substrate and the anti-privacy coating. The substrate is usually made of materials with high transparency and good mechanical properties such as polyester film or polycarbonate. The anti-privacy coating is a special coating applied to the substrate, which contains tiny prism structures or optical interference materials. These materials can limit the propagation angle of light and achieve an anti-privacy effect. However, the anti-privacy film is also limited by the substrate during use: when the anti-privacy film containing the substrate is used in scenarios such as fingerprint unlocking, the unlocking will be insensitive or impossible. In addition, when the anti-privacy film containing the substrate is used in curved screen display devices, the presence of the substrate will cause the anti-privacy film itself to easily warp.

[0004] Therefore, the utility model proposes an anti-peeping structure. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an anti-peeping structure that solves the problem that existing anti-peeping films are limited by the substrate during use and are difficult to apply to screen fingerprint unlocking or curved screen electronic products.

[0006] To achieve the above objectives, an anti-peeping structure is provided according to an embodiment of the first aspect of the present invention, comprising:

[0007] A substrate and a pre-coating layer, wherein a plurality of micro-nano pillars are fixedly connected to a side of the substrate near the pre-coating layer, and the pre-coating layer is fixed to the surface of the micro-nano pillars; the plurality of micro-nano pillars are evenly arranged on the surface of the substrate, and the dimensions of the micro-nano pillars decrease in a cross-section toward the pre-coating layer. The micro-nano pillars are arc-shaped on the side facing the pre-coating layer and at the connection position with the substrate on the cross-section. The center of the arc-shaped structure of the micro-nano pillar on the side facing the pre-coating layer is located inside the micro-nano pillar, while the center of the arc-shaped structure at the connection position of the micro-nano pillar and the substrate is close to the pre-coating layer.

[0008] The anti-peep layer is fixedly connected to the side of the pre-coating layer away from the substrate. The anti-peep layer and the pre-coating layer are both formed of a glue structure, and the pre-coating layer is made of soft glue.

[0009] Optionally, the substrate is made of PET transparent optical material.

[0010] Optionally, the pre-coating layer is made of high-elastic UV glue and is arranged on the side of the micro-nano column away from the substrate through UV molding.

[0011] Optionally, the pre-coating layer has a thickness of 15-20 microns.

[0012] Optionally, the anti-peep layer includes light-transmitting blocks and light-shielding blocks that are arranged at intervals, the light-transmitting blocks are evenly arranged, and the size of each light-transmitting block is consistent, and the light-shielding blocks are also evenly arranged, and the size of each light-shielding block is consistent.

[0013] Optionally, the light-transmitting block is made of anti-peeping white glue, and the light-shielding block is made of anti-peeping black glue, and the sides of the light-transmitting block and the light-shielding block away from the pre-coating layer are flat.

[0014] Compared with the prior art, the beneficial effects of the present invention are: an independent pre-coating layer is arranged between the substrate and the anti-peeping layer, the anti-peeping layer is arranged on the surface of the pre-coating layer, and a number of micro-nano pillars are arranged between the pre-coating layer and the substrate. The pre-coating layer is fixed in position with the substrate through the micro-nano pillars, and the adhesion between the pre-coating layer and the material is reduced by the shape of the micro-nano pillars, so that the substrate and the pre-coating layer can be peeled off under the action of force; and the substrate can provide a horizontal and relatively solid area when making the anti-peeping structure, which is convenient for material combination. When the anti-peeping structure needs to be used for curved screens or electronic products that are unlocked by screen fingerprints, the substrate can be peeled off and the anti-peeping structure composed of the pre-coating layer and the anti-peeping structure can be directly used. The overall structure is thinner and will not hinder the device recognition of the electronic product screen. The pre-coating layer can be directly adhered to the surface of the electronic product to prevent warping. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-3 As shown, an anti-peeping structure includes a substrate 11, a pre-coating layer 12, and an anti-peeping layer. A plurality of micro-nano pillars 13 are fixedly connected to a side of the substrate 11 near the pre-coating layer 12. The plurality of micro-nano pillars 13 are evenly arranged on the surface of the substrate 11. The cross-section of the micro-nano pillars 13 decreases in size toward the pre-coating layer 12. The side of the micro-nano pillars 13 facing the pre-coating layer 12 and the connection position with the substrate 11 are both arc-shaped. The center of the arc-shaped structure of the micro-nano pillars 13 facing the pre-coating layer 12 is located inside the micro-nano pillars 13, while the center of the arc-shaped structure of the micro-nano pillars 13 at the connection position with the substrate 11 is away from the substrate 11.

[0022] It should be noted that the micro-nano pillars 13 on the side of the substrate 11 close to the pre-coating layer 12 are formed by plasma coating, so that the side of the substrate 11 close to the pre-coating layer 12 has the characteristics of small water drop angle and low adhesion.

[0023] The anti-peeping layer is fixedly connected to the side of the pre-coating layer 12 away from the substrate 11. The anti-peeping layer and the pre-coating layer 12 are both formed of a glue structure, and the pre-coating layer 12 is made of soft glue. The pre-coating layer 12 is fixed to the surface of the micro-nano pillars 13;

[0024] In actual application, the anti-peeping structure is provided with an independent pre-coating layer 12 between the substrate 11 and the anti-peeping layer, the anti-peeping layer is provided on the surface of the pre-coating layer 12, and a plurality of micro-nano pillars 13 are provided between the pre-coating layer 12 and the substrate 11. The pre-coating layer 12 is fixed to the substrate 11 by the micro-nano pillars 13, and the adhesion between the pre-coating layer 12 and the material is reduced by the shape of the micro-nano pillars 13, so that the substrate 11 and the pre-coating layer 12 can be peeled off under the action of force; and the substrate 11 can provide a horizontal and relatively strong area when making the anti-peeping structure, which is convenient for material combination. When the anti-peeping structure needs to be used for a curved screen or an electronic product that is unlocked by a screen fingerprint, the substrate 11 can be peeled off and the anti-peeping structure composed of the pre-coating layer 12 and the anti-peeping structure can be directly used. The overall structure is thinner and will not hinder the device recognition of the electronic product screen. In addition, the pre-coating layer 12 can be directly adhered to the surface of the electronic product to prevent warping.

[0025] In some specific embodiments, the privacy layer includes light-transmitting blocks 21 and light-shielding blocks 22 arranged at intervals. The light-transmitting blocks 21 are evenly arranged, and the size of each light-transmitting block 21 is consistent. The light-shielding blocks 22 are also evenly arranged, and the size of each light-shielding block 22 is consistent. The intersection line of the extended surfaces of the two side walls of the light-transmitting blocks 21 can be close to the pre-coating layer 12 or away from the pre-coating layer 12.

[0026] In a further embodiment, the light-transmitting block 21 is made of anti-peeping white glue, and the light-shielding block 22 is made of anti-peeping black glue, and the sides of the light-transmitting block 21 and the light-shielding block 22 away from the pre-coating layer 12 are flat.

[0027] It should be noted that the light-transmitting block 21 includes but is not limited to structures with straight edges such as pyramids and cones. The edge of the cross section of the light-transmitting block 21 may be arc-shaped, and the center point of the arc may be located inside the light-transmitting block 21 or inside the light-shielding block 22.

[0028] In some specific embodiments, the pre-coating layer 12 is made of a highly elastic UV adhesive and is disposed on the side of the micro-nano pillars 13 away from the substrate 11 by UV molding;

[0029] It should be noted that the high-elastic UV glue is a soft glue among UV glues, and has better softness and resilience after UV molding; that is, the pre-coating layer 12 made of the high-elastic UV glue is soft after being peeled off from the substrate 11, and can better fit the curved screen;

[0030] In a further embodiment, the thickness of the pre-coating layer 12 is 15-20 microns;

[0031] In some specific embodiments, the substrate 11 is made of PET light-transmitting material;

[0032] It should be noted that the substrate 11 includes but is not limited to transparent optical materials such as PET, PVC, EVA, PC, PMMA, TPU, and glass;

[0033] The working principle of the present invention is: when the anti-peep film is applied to electronic products with curved screens or screen fingerprint unlocking, manual force or mechanical force is applied to peel off the substrate 11 and the pre-coating layer 12. After the substrate 11 is peeled off, the pre-coating layer 12 is directly adhered to the screen.

[0034] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
