Description

Screen protector structure improvement

This creation is related to a protective sticker, especially a screen protector structure.

Press, Newton’s rings, also known as Newton's rings, are optically equivalent to thin film interference. The protection stickers that appear on touch screens such as mobile phones and tablets are commonly known as "rainbow patterns." The presence of the rainbow pattern will affect the transparency and visual effect of the protective sticker, and cause the screen to be unsightly and affect the vision. In general, the rainbow pattern is because the film substrate needs to undergo a high temperature during the hardening treatment, and in the high temperature treatment, the molecular structure of the film substrate surface is unevenly distributed to cause scattering; the hardening treatment of high hardness is required, the rainbow pattern Elimination or reduction is more difficult to control.

In the current technology, in addition to controlling the hardening treatment of the film substrate, the resin having a high refractive index is selected through the film substrate, the thickness error is controlled, or the coating is applied by a high-precision coating method to reduce the coating. Thickness deviations, etc., are ways to reduce or eliminate rainbow lines.

However, the above solution is mostly to overcome the rainbow pattern phenomenon of the protection sticker itself, but when the protection sticker is attached to the screen, it is still possible to generate a rainbow phenomenon due to uneven contact with the screen. The protective stickers are mostly high-hardness protective stickers, and in order to avoid sticking to the screen, the film coating corresponding to the screen portion is omitted because the bubbles are not easily eliminated, and only the protective film is coated in the periphery of the protective tape. After coating, it is attached to the periphery of the screen of the mobile phone or tablet, thereby reducing the problem that the protective sticker is likely to generate bubbles on the bonding. However, there is a gap between the screen and the screen without the adhesive coating, and in the past, the protective coating has a film coating of 0.05 mm or less, and the resulting void is less than 0.05 mm. Rainbow ripple is also likely to occur under such extremely fine voids.

In view of this, the creator is trying to improve and solve the above-mentioned shortcomings, and he has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

The main purpose of this creation is to provide an improved screen protector structure that is controlled by thickness to eliminate or reduce the rainbow pattern created between the protector and the screen.

In order to achieve the above object, the present invention provides a screen protector structure improvement comprising a protective layer, an adhesive layer, and a release layer; the protective layer has a back surface, and the adhesive layer is laminated and adhered to the back surface of the protective layer. The release layer is further laminated and adhered to the adhesion layer such that the adhesion layer is located between the protective layer and the release layer; wherein the adhesion layer is formed with a closed hollow region, and the hollow region is located at the protective layer and the release layer The height formed between them is between 0.06 mm and 0.10 mm.

In order to achieve the above purpose, the present invention provides an improved screen protector structure for adhering to an electronic product screen, including a protective layer and an adhesive layer; the protective layer has a back surface, and the adhesive layer is laminated and bonded to a back surface of the protective layer for adhering to the periphery of the screen; wherein the adhesive layer is formed with a peripherally closed hollow area, the hollow area corresponding to the screen, and the hollow area is located between the protective layer and the screen The height formed between the two is between 0.06 mm and 0.10 mm.

In order to further disclose the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are only for reference and description, and are not intended to limit the creation.

Please refer to FIG. 1 and FIG. 2 , which are respectively a perspective exploded view and a partial cross-sectional view of the present creation. The present invention provides an improved screen protector structure, which can be applied to an electronic product 4 having a touch screen such as a mobile phone or a tablet (i.e., as shown in FIG. 3). The screen protector comprises a protective layer 1, an adhesive layer 2, and a release layer 3 before being adhered to the electronic product 4; wherein:

The protective layer 1 can be made of a material such as glass and serves as a substrate for the protective sticker to protect the screen with better hardness. The protective layer 1 has a back surface 10 for laminating and bonding the adhesion layer 2 to form the screen protection sticker.

The adhesive layer 2 is laminated and adhered to the back surface 10 of the protective layer 1, and the adhesive layer 2 is formed with a peripherally closed hollow area A, and the present invention mainly controls the thickness D of the adhesive layer 2, The hollowed out area A can produce a height gap of between 0.06 mm and 0.10 mm between the protective layer 1 and the screen of the electronic product 4. In the embodiment of the present invention, the adhesive layer 2 also has a layered structure and has a film substrate 20, a lower compound 21 and a top compound 22, and the film substrate 20 is on the film substrate 20. That is, a middle closed hollow portion 200 is formed, and the lower rubber 21 and the upper rubber 22 are respectively formed with a closed hollow portion 210 and an upper hollow portion 220 respectively, and the lower rubber 21 is adhered to the rubber. On the surface of the film substrate 20, the sizing material 22 is adhered to the other surface of the film substrate 20, and when the film substrate 20, the lower compound 21 and the sizing material 22 are laminated and bonded together, The middle hollow portion 200, the lower hollow portion 210 and the upper hollow portion 220 may constitute the aforementioned hollowed out area A, that is, as shown in FIG.

Further, in one mode of the preferred embodiment of the present invention, the thickness D of the adhesive layer 2 may be 0.075 mm, and the rubber 21 therein may be an acrylic film, and the glue is applied. The material 22 can be a silicone film. Generally, the thickness of the film substrate 20 is usually 0.025 mm. Therefore, the thickness of the undersize 21 and the size 22 are both adjusted to 0.025 mm, so the total of the three layers is 0.075mm. In another mode of the preferred embodiment of the present invention, the thickness of the film substrate 20 can be adjusted to 0.050 mm, and the thickness of the lower compound 21 and the sizing material 22 is generally 0.0125 mm, so that the three layers are laminated. The total after is still 0.075mm.

The release layer 3 is laminated and adhered to the adhesion layer 2 such that the adhesion layer 2 is located between the protective layer 1 and the release layer 3, thereby maintaining the viscosity of the screen protection sticker before it is used. At the same time, it can be separated from the adhesive layer 2 when it is intended to be used. In the embodiment of the present invention, the adhesive layer 2 is adhered to the back surface 10 of the protective layer 1 , and the release layer 3 is adhered to the lower compound 21 to form a book. Create the screen protector (before use).

Accordingly, as shown in FIG. 3 and FIG. 4, when the screen protection sticker is to be attached to an electronic product 4 (which may be a mobile phone or a tablet), the electronic product 4 mainly has a front surface 40, and The front surface 40 is divided into a screen area 400 and a panel area 401, and the hollow area A of the adhesion layer 2 corresponds to the screen area 400, and the glue 21 under the adhesion layer 2 is adhered to the periphery of the screen area 400 to make the protective layer. 1 substantially covers the entire screen area 400 and the panel area 401 (regardless of the actual opening/receiving hole of the electronic product 4, the physical button or the lens, etc.). As shown in the enlarged view of part B of FIG. 4, since the present invention controls the thickness D of the adhesive layer 2, the hollow area A between the protective layer 1 and the screen of the electronic product 4 (ie, the screen area 400) is obtained. The height corresponding to the thickness D of the adhesive layer 2 can be formed, that is, the height is between 0.06 mm and 0.10 mm, so that the gap between the protective layer 1 and the screen can be increased to eliminate or reduce the gap between the protective sticker and the screen. The resulting rainbow pattern phenomenon can still be maintained without losing the touch sensitivity of the protective sticker, that is, no more than 0.10mm.

Therefore, by the above-mentioned structural composition, the structure of the creative screen protector can be improved.
