AI Technical Summary
When peeling, the existing protective film is easily peeled from the inside to the outside due to interference of double-sided sticking, which leads to the problem of difficulty in peeling.
A liquid crystal panel protective film assembly that is easy to peel is designed, including a protective film and a release film. A tear handle is provided at one corner of the upper surface of the protective film, and a half-cut part is provided at one corner of the release film. The position of the half-cut part is adapted to the tear handle, and a half-tangent line is provided at the edge. When applying the film, the half-cut part of the release film is retained, and the release film at other positions is tear to attach it, reducing the adhesion between the protective film and the glass and reducing the resistance to the angle of the tear film.
Through this design, users can easily peel off the protective film through the tearing handle, effectively solving the problem of difficult peeling of the protective film. At the same time, due to the design of the half-cut part, the peripheral dirt can prevent the product from entering the visual area.

Abstract
Description
Technical Field
[0001] The utility model relates to a protective film, more specifically, to an easily peelable liquid crystal panel protective film component. Background Art
[0002] With the continuous advancement of film materials, protective films, double-sided adhesive tapes, sponges, double-sided adhesive tapes, diffusion films and other materials are widely used in module assembly. In the process of module frame pasting, double-sided adhesive tape and protective films are generally used in specific processes. The protective film will add a green flag or yellow flag as a tear-off position to facilitate tearing off the protective film before assembly. However, in many cases, due to the interference of double-sided adhesive tape, the tear-off position can only be designed close to the edge of the viewing area, which results in the initial peeling direction being peeled from the inside to the outside, which often leads to peeling difficulties and makes it difficult to complete the peeling action.
[0003] Chinese utility model patent document CN203994957U discloses an easy-tear and easy-positioning protective film, comprising a protective film layer, a first adhesive layer, a hardening layer, a main film layer, a second adhesive layer and a peeling layer arranged in sequence, the periphery of the peeling layer extends out of the periphery of the main film layer, and the edges of the peeling layer are provided with tearing openings. The length of the periphery of the peeling layer extending out of the periphery of the main film layer is 2-20 mm. The tearing opening is "V" shaped, triangular or semicircular. The thickness of the protective film layer is 30-100 μm, the thickness of the first adhesive layer is 8-30 μm, the thickness of the hardening layer is 2-10 μm, the thickness of the main film layer is 50-300 μm, the thickness of the second adhesive layer is 10-60 μm, the thickness of the peeling layer is 20-100 μm, and the thickness of the easy-tear and easy-positioning protective film is 120-500 μm. Both the first adhesive layer and the second adhesive layer are polyurethane resin adhesive layers, silicone resin adhesive layers or acrylic resin adhesive layers. The peeling layer and the protective film layer are both made of OPP, CPP, PI, PO, PET, PVC, EVA, PS, PU, PPE or CPE material layers. The main film layer is a PET main film layer with a total light transmittance of not less than 95% and a haze of less than 2%. The upper and lower surfaces of the main film layer are both provided with a corona layer. The easy-to-tear and easy-to-position protective film is provided with a through hole.
[0004] Obviously, the main film layer 4 of the patent after corona treatment has a light transmittance of 95% and a haze of 1.5%. The protective film has high light transmittance and low haze, ensuring that the screen using the protective film has good use effect and is comfortable to use. In addition, the through hole 7 is used to ensure that the protective film is more convenient to use for areas such as microphones, receivers, buttons, etc. on the mobile phone screen, and the service life of the protective film is extended. However, this structure cannot solve the problem of difficulty in peeling off the existing protective film.
[0005] Chinese utility model patent document CN216141483U discloses an easily peelable heat-reducing adhesive protective film, characterized in that: the heat-reducing adhesive protective film comprises a substrate layer, a pressure-sensitive adhesive layer, a heat-reducing adhesive layer, and an easily peelable layer; the heat-reducing adhesive protective film is formed by laminating the substrate layer, the pressure-sensitive adhesive layer, the heat-reducing adhesive layer, and the easily peelable layer in order from top to bottom. The raw material for preparing the heat-reducing adhesive layer is selected from a heat-sensitive adhesive material. The easily peelable layer is selected from a polyester release film. The thickness of the heat-reducing adhesive layer is not less than 18μm. The thickness of the easily peelable layer is 22-55μm. The thickness ratio of the substrate layer to the pressure-sensitive adhesive layer is 10:1. The total thickness of the heat-reducing adhesive layer and the easily peelable layer accounts for 20-40% of the total thickness of the heat-reducing adhesive protective film.
[0006] Obviously, this patent is not easy to break when the film is stretched, will not cause damage to the chip when expanded, and is not prone to shrinkage, wrinkles, and deformation. It is suitable for wafer processing and cannot solve the problem of difficulty in peeling off the existing protective film. Utility Model Content
