Description

Technical Field

[0001] This utility model relates to the field of protective film technology, and in particular to a protective film for a mobile phone screen brightness enhancement film. Background Technology

[0002] Brightness enhancement film is the most important component of mobile phone screen backlight modules. It increases the final brightness and transparency of the backlight module through light refraction and reflection. Its structure mainly includes a substrate, optical microstructures, and upper and lower protective films. The protective films can improve the brightness enhancement film's resistance to dirt, abrasion, and corrosion. To protect the brightness enhancement film from scratches and impacts, a protective film needs to be applied. The protective film applied to the brightness enhancement film is generally made of frosted material.

[0003] The existing protective film is easily broken by impact on the sides, but the sides are mostly integrated with the main body of the protective film.

[0004] First, cracks on the surrounding side parts may extend to the main body of the protective film, damaging the entire protective film and requiring its replacement, which increases the consumption of the protective film and the cost for consumers.

[0005] Secondly, it causes the surrounding side parts to be unable to be disassembled and removed from the main body of the protective film after being damaged, affecting the overall appearance of the protective film.

[0006] Third, the surrounding side parts cannot be removed separately to remove the protective film after damage, and the entire protective film needs to be replaced, which is also not conducive to reducing the user's cost. Utility Model Content

[0007] In view of this, the present invention provides a mobile phone screen brightening film protective film to solve the problem that cracks on the surrounding side parts may be transmitted and extended to the main body of the protective film, damaging the entire protective film and requiring the replacement of the entire protective film, which increases the consumption of protective film and the cost of using protective film for consumers.

[0008] The technical solution proposed by this utility model is: a protective film for enhancing the brightness of a mobile phone screen, specifically including a tempered glass substrate, wherein the shape of the tempered glass substrate is adapted to the shape of the mobile phone screen;

[0009] The tempered glass substrate is detachably and adhesively fitted with a glass base frame, and a thin covering film is adhesively applied to the top of the tempered glass substrate, and a thin side covering film is adhesively applied to the top of the glass base frame; the top surfaces of the tempered glass substrate and the glass base frame are aligned and flat, and the top surfaces of the side covering film are aligned and flat.

[0010] The tempered glass substrate has a beveled side section, and the outer side of the glass frame also has a beveled side section.

[0011] Furthermore,

[0012] The top part of the glass base frame is embedded with several protruding particles.

[0013] Furthermore,

[0014] The protruding particles are transparent and evenly distributed.

[0015] Furthermore,

[0016] The shape of the glass frame is adapted to the shape of the tempered glass substrate.

[0017] Furthermore,

[0018] A disassembly groove is provided on one side of the glass base frame.

[0019] Furthermore,

[0020] The first part of the disassembly groove extends to the side of the tempered glass substrate.

[0021] Furthermore,

[0022] The disassembly groove is located in the middle of the glass frame and the tempered glass substrate side.

[0023] The mobile phone screen brightening film provided by this utility model has the following beneficial effects:

[0024] In use, the glass frame and tempered glass substrate are detachable and separate, with a joint gap between the parts that are glued together. When the glass frame is broken by impact, the joint gap can interrupt and block the impact force and the resulting cracks. Compared with the existing technology where the surrounding side parts and the main body of the protective film are integrated, this can prevent cracks from extending to the tempered glass substrate and damaging the entire protective film. This helps to protect the tempered glass substrate from breakage and indirectly reduces the replacement cost of the entire protective film and the user's cost.

[0025] In addition, when the glass frame is shattered by an impact, it can be removed separately to eliminate the damage and restore the overall appearance of the protective film without having to replace the entire protective film.

[0026] In addition, the cover film and side cover film are used to shield and protect the tempered glass substrate and glass frame. When the cover film and side cover film are worn or scratched, they can be torn off to expose the top surface of the tempered glass substrate and glass frame for continued use, which helps to extend the overall service life of the protective film and further reduce the cost of use for consumers.

[0027] In addition, the tempered glass substrate has a beveled side and the outer side of the glass frame has a beveled side. This makes the angle formed by the bonding between the tempered glass substrate, the glass frame and the screen more than 10 degrees, which can reduce the amount of dust in the angle and make it easier to clean the dust accumulated in the angle.

[0028] In addition, the raised particles actually form an anti-glare layer. The surface of the raised particles has a certain unevenness, which can scatter more light that penetrates it, reduce the gloss of the display screen, make the image on the display screen lighter, achieve the anti-glare effect, and help reduce the damage of the display screen to the eyes.

[0029] In addition, the removal slot is located at the bottom of the cover film and the side cover film, which makes it easy to apply an upward pushing force to the cover film and the side cover film for prying or prying off, avoiding the problem of having no gripping structure on the cover film and the side cover film, which would make tearing and disassembly troublesome and difficult.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0044] Please refer to Figures 1 to 6 ;

[0045] Example 1:

[0046] This utility model proposes a protective film for a mobile phone screen brightness enhancement film, including a tempered glass substrate 1, the shape of which is adapted to the shape of the mobile phone screen;

[0047] The tempered glass substrate 1 is detachably adhesively fitted with a glass frame 2. The glass frame 2 and the tempered glass substrate 1 are detachably separate, with a joint between them. When the glass frame 2 is impacted and shattered, this joint can interrupt and prevent the impact force and resulting cracks. Compared to existing technologies where the surrounding sides are integrated with the protective film, this prevents cracks from extending to the tempered glass substrate 1 and damaging the entire protective film. This helps to protect the tempered glass substrate 1 from breakage, indirectly reducing the need for replacing the entire protective film and lowering user costs. Furthermore, when the glass frame 2 is impacted and shattered, it can be removed separately to repair the damage and restore the overall appearance of the protective film, eliminating the need to replace the entire film. The tempered glass substrate 1... A thin cover film 101 is adhesively attached to the top of the tempered glass substrate 1, and a thin side cover film 201 is adhesively attached to the top of the glass base frame 2. The top surfaces of the tempered glass substrate 1 and the glass base frame 2 are aligned and flat, and the top surfaces of the side cover film 201 are aligned and flat with the top surfaces of the cover film 101. This allows for easy finger touch and sliding, avoiding any protruding or uncomfortable feeling on the fingers, and making the touch smooth and comfortable. The cover film 101 and the side cover film 201 are used to shield and protect the tempered glass substrate 1 and the glass base frame 2. When the cover film 101 and the side cover film 201 are worn or scratched, they can be torn off and removed to expose the top surfaces of the tempered glass substrate 1 and the glass base frame 2 for continued use. This helps to extend the overall service life of the protective film and further reduces the user's cost.

[0048] The tempered glass substrate 1 has a beveled side, and the outer side of the glass frame 2 has a beveled side. This makes the angle formed by the bonding between the tempered glass substrate 1, the glass frame 2 and the screen more than 90 degrees, which can reduce the amount of dust in the angle and make it easier to clean the dust accumulated in the angle.

[0049] Preferred,

[0050] Several raised particles 102 are embedded in the top part of the glass base frame 2. The raised particles 102 essentially form an anti-glare layer. The surface of the raised particles 102 has a certain unevenness, which can scatter more light that penetrates it, reduce the gloss of the display screen, make the image on the display screen lighter, achieve the anti-glare effect, and help reduce the damage of the display screen to the eyes.

[0051] Preferred,

[0052] The raised particles 102 are transparent and evenly distributed.

[0053] Preferred,

[0054] The shape of the glass base frame 2 is adapted to the shape of the tempered glass substrate 1.

[0055] Based on Example 1, Example 2:

[0056] A disassembly groove 3 is provided on one side of the glass base frame 2.

[0057] Preferred,

[0058] The first part of the disassembly groove 3 extends to the side of the tempered glass substrate 1.

[0059] Preferred,

[0060] The disassembly groove 3 is located in the middle of the side of the glass base frame 2 and the tempered glass base 1. The disassembly groove 3 is placed at the bottom of the cover film 101 and the side cover film 201, which can facilitate the application of an upward pushing force to the cover film 101 and the side cover film 201 for prying or prying off, avoiding the lack of a support structure on the cover film 101 and the side cover film 201, which would make tearing and disassembly troublesome and difficult.

[0061] Working principle: The glass frame 2 and the tempered glass substrate 1 are detachably separated. The parts that are glued together form a joint gap. When the glass frame 2 is broken by impact, the joint gap can interrupt and block the impact force and the resulting crack, preventing the crack from extending to the tempered glass substrate 1 and damaging the entire protective film, thus providing anti-shatter protection for the tempered glass substrate 1.

[0062] The covering film 101 and the side covering film 201 are used to shield and protect the tempered glass substrate 1 and the glass frame 2. When the covering film 101 and the side covering film 201 are worn and scratched, they can be torn off and removed to expose the top surface of the tempered glass substrate 1 and the glass frame 2 for continued use.

[0063] The angle formed by the bonding between the tempered glass substrate 1, the glass frame 2 and the screen is greater than 90 degrees, which can reduce the amount of dust trapped and make it easier to clean the dust.

[0064] The raised particles 102 essentially form an anti-glare layer. The surface of the raised particles 102 has a certain unevenness, which can scatter more light that penetrates it, reduce the gloss of the display screen, and make the image on the display screen fade, thus achieving an anti-glare effect.
