Description

Technical Field

[0001] The utility model relates to the technical field of glass etching and vacuum coating, in particular to a soft light screen protective film with nano texture. Background Art

[0002] Currently, most screen protectors for mobile phones, tablets, computers and other electronic products on the market have a strong reflective effect. When the ambient light reaches a certain intensity, the strong reflection will reduce the clarity of the screen and make it difficult to see the content. Especially when used outdoors under strong light conditions, the electronic screen with this kind of screen protector is very dazzling, affecting the user experience.

[0003] In view of the above defects, a soft light screen protective film with nano-texture is proposed. The protective film has an AG effect of nano-texture through glass etching technology, which can change the reflection mode of light, changing direct reflection to diffuse reflection, greatly reducing the intensity of reflected light entering the eye; at the same time, a transmittance-enhancing and anti-reflection (AR) nano-film layer and a waterproof and oleophobic (AF) layer are plated on the glass etching surface by vacuum electroplating technology, which further reduces the reflected light of the protective film, increases its transmittance to improve the clarity of the electronic screen, and also makes the surface anti-fingerprint; the other side of the protective film is plated with a rare earth anti-blue light film layer to give it an anti-blue light effect. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a soft light screen protective film with nano texture. The AG effect of the nano texture and the AR effect of the anti-transmittance and anti-reflection film layer can reduce the direct reflectivity of the product to less than 2%, and the reflection can be soft and not dazzling under strong light. At the same time, the product is coated with anti-blue light and waterproof oleophobic film layer, so it also has the effect of anti-blue light and anti-fingerprint.

[0005] The technical solution to achieve the purpose of the utility model is: a soft light screen protective film with nano texture, comprising a glass substrate, one side of the glass substrate is provided with an AG effect surface, the side of the glass substrate provided with the AG effect surface is provided with an anti-reflection and anti-reflection film layer, the other side of the glass substrate is provided with a silicon dioxide layer four, one side of the silicon dioxide layer four is provided with an anti-blue light film layer, and one side of the anti-blue light film layer is provided with a silicon dioxide layer five;

[0006] The anti-reflection and anti-reflection film layer comprises a first silicon dioxide layer, zirconium dioxide, a second silicon dioxide layer, lanthanum titanate and a third silicon dioxide layer.

[0007] In some embodiments, the silica layer 1 is arranged on the side of the glass substrate on which the AG effect surface is arranged, the zirconium dioxide is arranged on the side of the silica layer 1 away from the glass substrate, the silica layer 2 is arranged on the side of the zirconium dioxide away from the silica layer 1, the lanthanum titanate is arranged on the side of the silica layer 2 away from the zirconium dioxide, and the silica layer 3 is arranged on the side of the lanthanum titanate away from the silica layer 2.

[0008] In some embodiments, the thickness of the glass substrate is 0.3 mm, and the thickness of the silicon dioxide layer 1 and the silicon dioxide layer 4 are both 22 nm.

[0009] In some embodiments, the thickness of the zirconium dioxide layer and the silicon dioxide layer three are both 80 nm, and the thickness of the silicon dioxide layer two and the AF water-repellent and oleophobic layer are both 60 nm.

[0010] In some embodiments, the thickness of the lanthanum titanate is 120 nm, and the thickness of the anti-blue light film layer is 240 nm.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First: The utility model uses a self-prepared glass frosting liquid to acid-etch one side of the glass sheet, so that the glass surface presents a nano-level texture and has an AG effect, which can change direct reflection into diffuse reflection, so that the product surface obtains a soft light effect;

[0013] Second: The utility model adopts vacuum electroplating technology: using electron gun vacuum coating equipment, under vacuum state, the high-energy electron beam emitted by the electron gun bombards anti-reflection (AR) materials, rare earth anti-blue light materials and waterproof oleophobic (AF) pills and other coating materials, so that the materials can obtain enough energy for melting, evaporation or direct sublimation, and at the same time, an ion source is used to excite the inert gas and make it obtain huge kinetic energy, so as to assist the plating of the evaporated or sublimated coating material particles, accelerate the deposition of the coating material particles on the substrate surface, and form a uniform and dense nano-thin film.

[0014] The invention solves the problem that most of the screen protection films of existing electronic products have a large reflective effect. When the ambient light reaches a certain intensity, the large reflection will cause the screen clarity to decrease and the content to be unclear. Especially when used outdoors under strong light conditions, the electronic screen with such screen protector is very dazzling, affecting the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
