Description
Technical Field
[0001] The utility model relates to a touch screen, more specifically, to a touch screen optical film without white edges. Background Art
[0002] When making touch screens, the optical film and the touch screen are almost the same size. The process will allow the film material to shrink inward by 0.5mm on one side based on the periphery of the touch screen. Since this 0.5mm single-sided gap is between the edge of the optical film and the periphery of the touch screen, it creates a white edge phenomenon visually, affecting the appearance.
[0003] Chinese utility model patent document CN206373039U discloses a white edge eliminating liquid smear pen, including a liquid storage capsule, a fiber refill and a pen cap, wherein the liquid storage capsule stores transparent white edge eliminating liquid, the liquid storage capsule has a liquid outlet channel, the fiber refill is inserted into the liquid outlet channel, and one end of the fiber refill is a liquid suction end, and the other end is a liquid outlet end, the liquid suction end extends into the liquid storage capsule, and the liquid outlet end extends out of the liquid outlet channel, and the pen cap covers the outer periphery of the liquid outlet end of the fiber refill. The white edge eliminating liquid smear pen also includes a handle, the handle is fixed to one end of the liquid storage capsule away from the fiber refill, and the length direction of the handle is the same as the length direction of the liquid storage capsule. The handle is flat. The white edge eliminating liquid smear pen also includes a fixing frame, the fixing frame is embedded in the liquid outlet channel, the fiber refill is installed in the liquid outlet channel through the fixing frame, and the outer periphery of the fiber refill and the inner wall of the liquid outlet channel are sealed by the fixing frame. The liquid outlet end of the fiber pen core is tapered. The liquid storage bag is made of soft material.
[0004] Obviously, this patent uses smearing to eliminate white edges, which has limited effect and requires a lot of manual effort.
[0005] Chinese invention patent document CN110568623A discloses a method for eliminating white edges displayed by a 3D-LED module. The 3D-LED module includes n 3D polarizing films, n LED display modules and a light-transmitting layer; the n spliced 3D polarizing films are located between the light-transmitting layer and the n spliced LED display modules, and the n 3D polarizing films correspond to the n LED display modules one by one; the method for eliminating white edges is as follows: m light-absorbing grating structures are implanted at the edge of the 3D polarizing film, so that m prism reflection structures are formed along the splicing line at the splicing point of any two 3D polarizing films, each prism reflection structure is formed by combining two light-absorbing grating structures, and the m prism reflection structures on the splicing line are used to reflect the light output by the LED display module through the splicing point to the outside of the field of view on the left and right sides, thereby eliminating white edges. The method of implanting m light-absorbing grating structures at the edge of the 3D polarizing film further includes the following steps: Step 1, setting the 1 / 2 phase difference film 103 on the side of the circular polarizing plate 100 away from the LED display module; Step 2, forming m light-absorbing grating structures 101 in the edge empty lines of the 1 / 2 phase difference film 103, and the right-angle section of the light-absorbing grating structure 101 is flush with the edge of the circular polarizing plate 100; Step 3, splicing n circular polarizing plates 100 with light-absorbing grating structures implanted and 1 / 2 phase difference films attached thereto; Step 4, uniformly flattening the empty lines of the n 1 / 2 phase difference films 103; Step 5, forming an anti-reflection layer 300 to complete the production of the 3D polarizing film. The bottom surface of the light-absorbing grating structure 101 is placed on the circular polarizing plate 100. The light-absorbing grating structure 101 is composed of a mixture of UV polymer and light-absorbing particles. The light-absorbing grating structure 101 is implanted in the edge empty lines of the 1 / 2 phase difference film 103 through a complementary mold. The prism reflection structure is an isosceles triangular prism column or an isosceles quadrangular prism column.
[0006] Obviously, the software control method used by Zhu Ali to pick up different contrast images to debug is particularly cumbersome and solve the problem of poor white edge effect; it solves the problem of white edge caused by light leakage at the joint of 3D-LED modules. The patent uses the refraction and reflection principles of prism columns to further eliminate the white edge problem. The patent uses software control to improve the white edge, which is too costly and has a very complicated structure. Utility Model Content
[0007] Based on this, it is necessary to provide a touch screen optical film without white edges for the above technical problems. The touch screen optical film without white edges comprises a rectangular film body, and the edge of the film body is provided with a square frame-shaped cut inner shrinkage, and the cut inner shrinkage and the film body are an integral structure. The width of the cut inner shrinkage is between 0.8 mm and 1.2 mm. The touch screen optical film without white edges is expanded by about 1.0 mm on one side on the basis of the periphery of the touch screen. The CCD captures the shape of the touch screen and the film material, and the adhesive surface of the film material and the surface of the touch screen are bonded. The periphery of the bonded film material will be larger than the touch screen. At this time, the laser process is used to perform a 0.1 mm unilateral shrinkage cut on the basis of the periphery of the touch screen, and the film material of the extra touch screen is removed, thereby obtaining a touch screen without white edges. Since the sample after laser trimming has only a gap of 0.1 mm, it is difficult for the naked eye to identify whether there is a film material, which greatly improves the aesthetics of the sample. At the same time, since the film material is larger than the periphery of the touch screen, some deviations during patching can also be absorbed by the larger film material, which increases the fault tolerance in the process.
[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0009] A touch screen optical film without white edges, characterized in that the touch screen optical film without white edges comprises a rectangular film body, the edge of the film body is provided with a square frame-shaped cut inner shrinkage, and the cut inner shrinkage and the film body are an integrated structure.

The appearance of the touch screen and the film material is captured by CCD, and the adhesive surface of the film material and the surface of the touch screen are bonded. The periphery of the bonded film material will be larger than the touch screen. At this time, a laser process is used to perform a 0.1 mm inward cut on one side on the basis of the periphery of the touch screen, and the film material that is extra to the touch screen is removed, thereby obtaining a touch screen without white edges. Since the sample after laser trimming has only a 0.1 mm gap, it is difficult for the naked eye to identify whether there is a film material, which greatly improves the aesthetics of the sample. At the same time, since the film material is larger than the periphery of the touch screen, some deviations during patching can also be absorbed by the larger film material, which increases the fault tolerance rate in the process.

The depth of the shrinkage groove is between 0.1 mm and 0.5 mm. Preferably, the depth of the shrinkage groove is 0.3 mm. With the arc-shaped shrinkage groove, the shrinkage groove can automatically shrink into a smooth cutting surface during laser trimming, further improving the aesthetics of the sample.
[0022] In addition, the shrinkage groove can be made into an inverted trapezoid. The depth of the shrinkage groove is between 0.1 mm and 0.5 mm. Preferably, the depth of the shrinkage groove is 0.3 mm. With the inverted trapezoidal shrinkage groove, the shrinkage groove can automatically shrink into a smooth cutting surface during laser trimming, further improving the aesthetics of the sample.

[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0033] As described in the background technology, with respect to the prior art, when manufacturing a touch screen, the optical film is almost the same size as the touch screen, and the process allows the film material to be shrunk by 0.5 mm on one side based on the periphery of the touch screen. Since this 0.5 mm single-sided gap is between the edge of the optical film and the periphery of the touch screen, a white edge phenomenon is visually produced, affecting the appearance.
[0034] In order to solve this technical problem, the utility model provides a touch screen optical film 1 without white edges, comprising a rectangular film body 2, the edge of the film body 2 is provided with a square frame-shaped cut inner shrink edge 3, and the cut inner shrink edge 3 is an integral structure with the film body 2. The width D of the cut inner shrink edge 3 is between 0.8 mm and 1.2 mm. Preferably, the width D of the cut inner shrink edge 3 is 1 mm.
[0035] Through the above structural design, the touch screen optical film 1 without white edges is expanded about 1.0mm on one side on the basis of the periphery of the touch screen. The CCD captures the shape of the touch screen and the film material, and the adhesive surface of the film material and the surface of the touch screen are bonded. The periphery of the bonded film material will be larger than the touch screen. At this time, the laser process is used to perform a 0.1mm inward cut on one side on the basis of the periphery of the touch screen, and the film material that is extra to the touch screen is removed, thereby obtaining a touch screen without white edges. Since the sample after laser trimming has only a 0.1mm gap, it is difficult to identify the presence of the film material with the naked eye, which greatly improves the aesthetics of the sample. At the same time, since the film material is larger than the periphery of the touch screen, some deviations during patching can also be absorbed by the larger film material, increasing the fault tolerance rate in the process.
