Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of liquid crystal protection films. By utilizing the magnetic attraction principle of magnetic members, regardless of the size, shape, and type of liquid crystal protection film, at the location selected by the user, it is related to adsorbing and fixing the liquid crystal protection film to a liquid crystal screen or a device having a display screen.
Background Art
[0002] Devices having a liquid crystal screen or a display, such as tablet terminals and personal computers, are necessities for modern people. As protection films to be attached to the liquid crystal screens or display screens provided on these devices, there have been developed a film for a pen tablet that optimizes inputting characters and illustrations on the liquid crystal screen with a touch pen, a film for a touch pen, and films and filters for preventing peeping when used in public places. There are many users who attach and use these liquid crystal protection films to liquid crystal screens or display screens.
[0003] However, although these liquid crystal protection films need to be attached to the liquid crystal screen or the display screen in a specific scene, when leaving the specific scene, it becomes a situation where the user wants to remove them. Therefore, conventionally, magnetic parts have been embedded in the liquid crystal protection film side from the beginning so that it can be quickly attached and detached and adhered.
Summary of the Invention
Problems to be Solved by the Invention
[0004] In a conventional liquid crystal protection film in which magnetism is incorporated from the beginning, since it magnetically adheres only to one end such as the upper end, the adhesion between the liquid crystal protection film and the liquid crystal screen or display screen may not be excellent. In addition, embedding magnetic parts in the protection film from the beginning requires cost, and users could not move the parts with magnetism. Furthermore, when the area of the bezel part, which is a frame surrounding the liquid crystal screen or display screen, is small, in a liquid crystal protection film in which magnetic parts are embedded from the beginning, it was not possible to adsorb and fix the part outside the liquid crystal screen. In addition, in a liquid crystal protection film without embedded magnetic parts, it was not possible to adsorb and fix it to the liquid crystal screen or display screen by a magnetic method. Therefore, there is room for improvement in these points.
[0005] Therefore, in the present invention, considering the above problems and needs, the main purpose is to provide a liquid crystal protection film magnetic adsorption device that can be quickly attached and detached to a device having a liquid crystal screen or display screen at a location where the user wants to adsorb, regardless of the size, shape, and type of the liquid crystal protection film.
Means for Solving the Problems
[0006] In order to achieve the above object, a plurality of magnetic adsorption devices 2 adhered to one side of the liquid crystal protection film 1 of the present invention and a plurality of magnetic adsorption devices 3 adhered to the liquid crystal screen or display screen side 4 are provided.
[0007] In the magnetic adsorption device 2, an adhesive sheet 23 made of an amorphous or crystalline thermoplastic polyester resin, an iron member or a nickel-plated member 21, and 22 made of a thermoplastic polyurethane elastomer to which these are adhered are provided. Among these, the adhesive sheet 23 part is adhered to the liquid crystal protection film 1.
[0008] The magnetic adsorption device 3 is a magnetic member, and on one side thereof, an adhesive sheet 31 made of an amorphous or crystalline thermoplastic polyester resin is provided. The adhesive sheet 31 portion is adhered to the upper frame portion, lower frame portion, and lateral frame portion of the liquid crystal screen monitor and the display screen main body based on the user's judgment, including the bezel portion of the liquid crystal screen or the display screen.
Advantages of the Invention
[0009] According to the liquid crystal protection film magnetic adsorption device of the present invention, any liquid crystal protection film of any size, shape, and type can be quickly attached to and detached from a device having a liquid crystal screen or a display screen, which improves its versatility and can reduce production costs compared to the case where magnetism is incorporated into the liquid crystal protection film in advance for attachment.
[0010] According to the user's usage needs, a plurality of adsorption locations can be freely selected based on the magnetic attraction principle, enabling the liquid crystal protection film according to the user's preference to be quickly attached to and detached from a device having a liquid crystal screen or a display screen.
[0011] According to the user's usage needs, by freely selecting a plurality of adsorption locations based on the magnetic attraction principle, it is possible to provide adsorption locations not only at the upper end but also at the left end, right end, and lower end, improving the adhesion between the liquid crystal protection film and the liquid crystal screen or the display screen.
[0012] Among the 22 in the magnetic adsorption device 2, by configuring the portion excluding the portion where the adhesive sheet 23 and the iron member or nickel-plated member 21 are adhered with a thermoplastic polyurethane elastomer, which is a member that can be folded into an L shape, even when the area of the bezel portion, which is a frame surrounding the liquid crystal screen or the display screen, is small, by adhering the magnetic adsorption device 3 to the upper frame portion, lateral frame portion, and lower frame portion of the liquid crystal screen or the display screen monitor main body, it is possible to quickly attach and detach the liquid crystal protection film to and from a device having a liquid crystal screen or a display screen without providing an adhesive portion on the liquid crystal screen or the display screen.
