Description

Technical Field

[0001] This utility model relates to the field of mobile phone screen protector technology, specifically a mobile phone screen protector with dual protection against blue light and UV rays. Background Technology

[0002] Light is divided into visible and invisible light. Infrared and ultraviolet light are invisible, while red, orange, yellow, green, blue, indigo, and violet light are visible. Ultraviolet (UV) light can be further divided into near-ultraviolet (UVC), mid-ultraviolet (UVB), and far-ultraviolet (UVA). The wavelength range of visible light in the electromagnetic spectrum is approximately 380nm-780nm, which is the portion of the electromagnetic spectrum that the human eye can perceive. Blue light is a type of visible light with relatively high energy, and its wavelength range in the electromagnetic spectrum is approximately 390nm-500nm. Excessively strong blue light can penetrate... Blue light penetrates the cornea and lens of the human eye and directly enters the macula, causing damage to the photoreceptor cells in the macula. At the same time, blue light irradiating the retina produces free radicals, which can lead to the death of retinal pigment epithelial cells, resulting in a lack of nutrients for photosensitive cells. In addition, blue light has a shorter wavelength and is scattered more severely than other visible light. When the eyes focus on it for a long time, it is easy to become fatigued and develop pseudomyopia. Blue light is not only present in ordinary light, but it is also widely present in the light emitted by various electronic products, such as smartphone screens, computer screens, LCD TV screens, or other LED-related products.

[0003] Therefore, more and more people are buying products with anti-blue light functions, such as anti-blue light lenses and anti-blue light screens, to prevent blue light from damaging the human eyes and causing eye diseases. Traditional screen protectors often produce glare, or even if anti-blue light and anti-UV protective films are used, the viewing effect on the mobile phone deteriorates. For this reason, we have proposed a mobile phone screen protector with dual protection against blue light and UV. Utility Model Content

The middle structure of the silicone release film layer is the PET base layer, and the end of the PET base layer facing away from the light-enhancing and light-transmitting layer is provided with an anti-scratch coating. The end face of the PET base layer corresponding to the light-enhancing and light-transmitting layer is provided with a silicone release agent layer that contacts and adheres to the optical adhesive layer.

[0009] Preferably, the anti-blue light UV layer consists of six parts: a silicon-containing surface layer one, an anti-blue light core layer, an adhesive layer, an anti-UV layer, a reflective layer, and a silicon-containing surface layer two.

[0011] Compared with the prior art, this utility model provides a mobile phone screen protector with dual protection against blue light and UV rays, which has the following beneficial effects:

[0012] This anti-blue light and UV dual protection mobile phone screen protector uses a light-enhancing and light-transmitting layer inside.

[0018] The technical solutions of the present 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 embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A dual-protection mobile phone screen protector with anti-blue light and UV protection includes a silicone release film layer 1, an anti-blue light UV layer 3, a silicone layer 5, and a light-enhancing and light-transmitting layer. The anti-blue light UV layer 3 is provided inside the light-enhancing and light-transmitting layer. The two contact surfaces of the anti-blue light UV layer 3 corresponding to the light-enhancing and light-transmitting layer are respectively provided with a silicone-containing surface layer 1 and a silicone-containing surface layer 2 14 to bond with the light-enhancing and light-transmitting layer. The two outer surfaces of the light-enhancing and light-transmitting layer opposite to the anti-blue light UV layer 3 are respectively provided with the silicone release film layer 1 and the silicone layer 5.

[0020] Furthermore, the light-enhancing and light-transmitting layer consists of two parts: an optical adhesive layer 2 and an optical-grade transparent polyester film 4. The optical adhesive layer 2 and the optical-grade transparent polyester film 4 do not contact each other. The end face of the light-enhancing and light-transmitting layer corresponding to the silicon release film layer 1 is the optical adhesive layer 2, and the end face of the light-enhancing and light-transmitting layer opposite to the silicon release film layer 1 is the optical-grade transparent polyester film 4. The optical adhesive layer 2 is made of photocurable pressure-sensitive adhesive or thermocurable pressure-sensitive adhesive.

[0021] Furthermore, one side of the optical-grade transparent polyester film 4 is treated with anti-glare to effectively eliminate glare caused by light, while the other side is treated with HC to have a hardness of 3H.

[0022] Furthermore, the silicone release film layer 1 is composed of an anti-scratch coating layer 6, a PET base layer 7, and a silicone release agent layer 8. The middle structure of the silicone release film layer 1 is the PET base layer 7, and the anti-scratch coating layer 6 is provided at the end of the PET base layer 7 facing away from the light-enhancing and light-transmitting layer. The silicone release agent layer 8 is provided on the end face of the PET base layer 7 corresponding to the end face of the light-enhancing and light-transmitting layer, which is in contact with and bonded to the optical adhesive layer 2. The anti-scratch coating layer 6 can greatly improve the hardness of its outer surface, effectively protect the mobile phone screen protector, prevent it from being scratched or abraded, and effectively improve its service life.

[0023] Furthermore, the anti-blue light UV layer 3 consists of six parts: a silicon-containing surface layer 9, an anti-blue light core layer 10, an adhesive layer 11, an anti-UV layer 12, a reflective layer 13, and a silicon-containing surface layer 2 14. The anti-blue light UV layer 3 has an anti-blue light core layer 10 at one end corresponding to the silicon-containing surface layer 9, and a reflective layer 13 at one end corresponding to the silicon-containing surface layer 2 14. The anti-UV layer 12 is located at the end of the reflective layer 13 facing away from the silicon-containing surface layer 2 14. An adhesive layer 11 is used to bond the anti-blue light core layer 10 and the anti-UV layer 12 together.

[0024] Furthermore, the silicone layer 5 is any one of polyurethane resin or solvent-based acrylic pressure-sensitive adhesive. The silicone layer 5 is purely electrostatically adsorbed, so it will not leave any residue even after long-term use. It will not leave any traces after disassembly and can be repeatedly pasted. The product is not prone to air bubbles and is securely installed. It can automatically adhere to the screen without leaving any residue or causing any damage to the screen.

[0025] Working principle: When correctly installed according to the diagram, this dual-protection screen protector for both blue light and UV protection adheres to the phone screen via a silicone layer 5. The silicone layer 5 uses pure electrostatic adsorption, ensuring no residue even after prolonged use and leaving no trace upon removal, providing maximum protection for the phone screen. When the phone is in use, the blue light and ultraviolet rays emitted by the phone are emitted outwards, passing through the silicone layer 5 and the optical-grade transparent polyester film 4 into the anti-blue light and UV layer 3. Inside the anti-blue light and UV layer 3, a reflective layer 13 partially reflects these rays, reducing eye damage. The remaining blue light and ultraviolet rays passing through the reflective layer 13 are effectively absorbed and intercepted by the anti-blue light core layer 10 and the anti-UV layer 12, significantly reducing their emission rate. An anti-scratch coating 6 is applied to the outer silicone release film layer 1 of the screen protector, effectively protecting the film.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
