[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0030] The utility model provides an explosion-proof film for avoiding AG friction damage, which includes a TAC film, an AG treatment layer, an AR treatment layer, an AF treatment layer and a high-transmittance adhesive, wherein the AG treatment layer is arranged on the lower surface of the TAC film; the AR treatment layer and the AF treatment layer are arranged on the upper surface of the TAC film; and the high-transmittance adhesive is arranged on the lower surface of the AG treatment layer.
[0031] Since the AG treatment layer is arranged on the lower surface of the TAC film and the high-transmittance adhesive is arranged on the lower surface of the AG treatment layer, that is, the high-transmittance adhesive covers the AG treatment layer and is adhered to the glass cover plate together with the high-transmittance adhesive, so that the AG treatment layer faces inward, and the AR treatment layer and the AF treatment layer face outward, so that the AG treatment layer is protected by the high-transmittance adhesive and the TAC film, avoiding the AG treatment layer from being damaged by friction, and making the explosion-proof film have a permanent anti-glare effect.
[0032] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.
[0033] See also Figure 1 , an explosion-proof film for preventing AG friction damage is provided by the utility model, which comprises a TAC film 1, an AG treatment layer 2, an AR treatment layer and an AF treatment layer 3 and a high-transmittance adhesive 4, wherein the AG treatment layer 2 is arranged on the lower surface of the TAC film 1; the AR treatment layer and the AF treatment layer 3 are arranged on the upper surface of the TAC film 1; and the high-transmittance adhesive 4 is arranged on the lower surface of the AG treatment layer 2. Since the AG treatment layer 2 is arranged on the lower surface of the TAC film 1 and the high-transmittance adhesive 4 is arranged on the lower surface of the AG treatment layer 2, that is, the high-transmittance adhesive 4 covers the AG treatment layer 2, and is adhered to the glass cover plate together with the high-transmittance adhesive 4, so that the AG treatment layer 2 faces inward, and the AR treatment layer and the AF treatment layer 3 face outward, so that the AG treatment layer 2 is protected by the high-transmittance adhesive 4 and the TAC film 1, and the AG treatment layer 2 is prevented from being damaged by friction, so that the explosion-proof film has a permanent anti-glare effect.
[0034] When the AR treatment layer and the AF treatment layer 3 are plated, the AR treatment layer and the AF treatment layer 3 can be plated in large pieces, which is more efficient and more stable than the traditional method of cutting into single pieces and then making the AR treatment layer and the AF treatment layer 3.
[0035] Furthermore, the high-transmittance adhesive 4 is PSA adhesive. PSA adhesive is the abbreviation of pressure-sensitive adhesive, which is a type of adhesive that is sensitive to pressure. It can make the explosion-proof film and the glass cover plate more sticky when they are bonded together.
[0036] See also Figure 2 Furthermore, a release film 5 is provided on the lower surface of the high-transmittance adhesive 4, and the release film 5 can be torn off when the explosion-proof film and the glass cover plate need to be attached.
[0037] See also Figure 3 As a further optimization scheme of Example 1, in this embodiment, a protective film 6 is provided on the upper surface of the AR processing layer and the AF processing layer 3 to protect the AR processing layer and the AF processing layer 3 from damage during transportation and production.
[0038] See also Figure 4 and Figure 5 Furthermore, the protective film 6 includes a base material layer 61 and an adhesive layer 62 , and the adhesive layer 62 is arranged below the base material layer 61 .
[0039] Furthermore, a film-tearing handle 63 is provided at the edge of the substrate layer 61 , and the film-tearing handle 63 is integrally formed with the substrate layer 61 , so that the protective film 6 can be easily torn off.
[0040] Before the explosion-proof film is attached to the glass cover, a tearing handle needs to be manually attached to a corner of the protective film 6 of the explosion-proof film. The corner should be pre-torn first, and then the protective film 6 should be torn off on the entire surface. When pre-tearing the corner of the protective film 6, bend and tear it with the thumb and fingernail. Since the thickness of the protective film 6 is relatively thin, the pressure of the fingernail will be transmitted to the explosion-proof film body through the protective film 6, causing the corner of the explosion-proof film body to be squeezed and cracked, resulting in a defective rate of about 25% in actual production. Therefore, further, a thickening layer 64 is provided on the tearing handle 63. Since the thickening layer 64 is provided on the tearing handle 63, the thickness of the entire tearing handle 63 is increased. When the fingernail is pressed on the protective film 6, the pressure is better dispersed due to the increased thickness of the tearing handle 63, thereby reducing the local pressure of the explosion-proof film, thereby avoiding the problem of cracks in the explosion-proof film, reducing the defective rate of the explosion-proof film, and improving the competitiveness of the product.
[0041] In this embodiment, the film-tearing handle 63 extends outwards for a certain distance and is suspended in the air. The thickness of the film-tearing handle 63 after adding the thickened layer 64 is greater than the thickness of the protective film 6 .
[0042] See also Figure 6 Furthermore, the thickened layer 64 extends to the entire substrate layer 61 , and at this time, the thickness of the film tearing handle 63 is equal to the thickness of the substrate layer 61 .
[0043] Further, the sum of the thicknesses of the adhesive layer 62, the substrate layer 61 and the thickening layer 64 is 90 μm. More preferably, the thickness of the adhesive layer 62 is 15 μm, and the sum of the thicknesses of the substrate layer 61 and the thickening layer 64 is 75 μm.
[0044] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0045] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
