Description

Technical Field

[0001] This invention relates to the field of protective film technology, and more specifically, to a wear-resistant and eye-protecting protective film for a telephone watch and a telephone watch. Background Technology

[0002] Currently, screen protectors for smartwatches generally have the following defects: 1. Low surface hardness, easily scratched and worn, resulting in a short service life; 2. Lacking effective eye protection, short-wave blue light and mirror reflections can easily cause visual fatigue; 3. Fingerprint residue is severe, difficult to clean, and affects the display effect; 4. Poor surface fit, prone to edge lifting, dust ingress, and air bubbles.

[0003] Most existing screen protectors for children's smartwatches only offer a single function of reducing blue light, failing to achieve integrated designs such as high wear resistance, eye protection, stain resistance, and curved surface adaptation, thus failing to meet the needs of high-frequency usage scenarios. Summary of the Invention

[0004] The technical problem to be solved by this invention is how to make the protective film of the phone watch have functions such as high hardness and wear resistance, blue light protection and eye protection, stain resistance and curved surface adaptation, so as to meet the needs of high-frequency use scenarios.

[0005] The technical problem to be solved by the present invention is achieved through the following technical solution: To address the aforementioned technical problems, this invention provides a wear-resistant and eye-protecting protective film for a phone watch, comprising, from top to bottom, an anti-fingerprint and oleophobic layer, a hardened and wear-resistant layer, a blue light absorbing layer, a transparent substrate layer, and a silicone adhesive layer, stacked sequentially. The anti-fingerprint and oleophobic layer is a nanoscale coating that is both fingerprint-resistant and hydrophobic. The hardened and wear-resistant layer is made of a nanoscale silica composite hardening material. The blue light absorbing layer is made of a composite material of an organic blue light absorber and an optical adhesive. The silicone adhesive layer is made of highly elastic, silent silicone.

[0006] As a preferred embodiment of the wear-resistant and eye-protecting phone watch protective film provided by the present invention, the thickness of the anti-fingerprint oleophobic layer is 20nm-100nm.

[0008] In a preferred embodiment of the wear-resistant and eye-protecting protective film for telephone watches provided by the present invention, the thickness of the hardened wear-resistant layer is 5μm-15μm.

[0009] In a preferred embodiment of the wear-resistant and eye-protecting phone watch protective film provided by the present invention, the material of the transparent substrate layer is a PET high-transparency substrate or a COP high-transparency substrate.

[0010] In a preferred embodiment of the wear-resistant and eye-protecting protective film for telephone watches provided by the present invention, the thickness of the transparent substrate layer is 50μm-150μm.

[0011] In a preferred embodiment of the wear-resistant and eye-protecting protective film for telephone watches provided by the present invention, the thickness of the silicone adhesive layer is 20μm-50μm.

[0012] As a preferred embodiment of the wear-resistant and eye-protecting phone watch protective film provided by the present invention, the wavelength of light absorbed by the blue light absorption layer is 400nm-450nm, and the light transmittance of the blue light absorption layer is greater than or equal to 92%.

[0013] The present invention provides a telephone watch, which includes the wear-resistant and eye-protecting telephone watch protective film as described in any of the above claims.

[0014] The present invention has the following beneficial effects: The anti-fingerprint and oleophobic layer is a nano-scale coating that is both fingerprint-resistant and hydrophobic. It reduces fingerprint adhesion, making oil stains easy to wipe away, improving stain resistance, simplifying fingerprint cleaning, and ensuring display quality. The hardened and wear-resistant layer is made of nano-scale silica composite hardening material, which has high surface hardness, is scratch-resistant, not easily scratched or worn, impact-resistant, and has a long service life. The blue light absorption layer is a composite material of organic blue light absorbers and optical adhesives, which can absorb harmful blue light without color distortion or yellowing, providing effective eye protection and preventing visual fatigue caused by short-wave blue light and mirror reflections. The silicone bonding layer is made of highly elastic, silent silicone, which can automatically expel air and prevent air bubbles, adapting to 2.5D and 3D curved surfaces, with good curvature fit and no edge lifting. This gives the phone watch screen protector high hardness and wear resistance, blue light protection, stain resistance, and curved surface adaptation, meeting the needs of high-frequency use scenarios.
