Description

Information protector and manufacturing method thereof

Technical Field

The present invention relates to an information protector which cannot see an image displayed on a display except for a front face or a designated angle.

Recently, personal and enterprise business processes have become profitable due to the rapid spread of personal computers and the establishment of network-based computer networks. That is, the user inputs information through an input device such as a keyboard or a mouse, and the result is displayed on the display. Therefore, it is more and more convenient to make private documents, refer to book materials in a library, perform money transactions in an ATM of a bank or a financial institution, or perform various business processes through a mobile phone and a Personal Digital Assistant (PDA), etc.

However, when people often pass around the periphery, when various video apparatuses such as a mobile phone, a cash dispenser, and a Personal Digital Assistant (PDA) process main information or data of an enterprise, a public office, and a person, or input data such as a password for performing a money transaction at an ATM and then display the data on a display, or perform various business processes using a mobile phone, care and fear are needed because information is exposed to the surrounding people.

Further, as the window glass surface of buildings and the like is becoming larger to ensure lighting and viewing angles, demands for protection of private life from the surrounding environment are becoming more stringent in the situation of ensuring viewing angles and lighting.

Therefore, it is necessary to develop an information protector as shown in fig. 5, in which although a user can easily see an image displayed on a screen, the user cannot see the image displayed on the screen from the perspective of people around the screen.

Further, such an information protector is also required for various display devices and the like that supply various screens in addition to the aforementioned devices.

Background

The conventional security film requires a cutting process after a process of applying a non-transparent adhesive pigment to a plurality of transparent films in a manufacturing process and performing an alternate adhesion lamination process (also referred to as a lamination process), thereby inevitably increasing the number of materials and manufacturing processes. This causes problems such as reduction in the productivity of security films and increase in the price of products. In addition, it is difficult to ensure the uniformity and clarity of the product in the step of applying a non-transparent adhesive pigment on a transparent film, alternately laminating the layers, and then cutting the layers.

In the conventional method for manufacturing a security film, a method for forming a concave-convex lattice on a film using a mold (mold press-bonding method) requires a large investment in the mold and its related manufacturing facilities to increase the product price, and when a film having a weak physical property is formed into a concave-convex lattice by applying a certain heat and pressure to the mold, the clarity is lowered due to film damage such as cracks and bending phenomena and the quality is lowered due to cracks, and thus it is difficult to secure a side protection function for shielding a transmission image to prevent a side view.

Disclosure of Invention

Accordingly, an object of the present invention is to provide a protector which prevents a user from seeing an image displayed on a screen at a peripheral angle (inclination angle) of a target screen (including a computer monitor, a glass of a general building, a mobile phone, a cash register, a palm computer, etc.) except for a predetermined angle set according to a purpose of use, an application, and a characteristic of a device at the time of front or manufacture.

In order to achieve the above object, the protector of the present invention comprises: a first film Layer and a shielding Layer (Blind Layer) formed by repeatedly arranging shielding walls shielding an incident image in a parallel or predetermined lattice shape along a predetermined angle to form an isolation distance; the shielding partition wall is formed by printing or transferring light-absorbing color ink on one side or both sides of the first film layer at least once.

Here, the width of the shielding walls is 5 to 100 μm, the height thereof is 10 to 250 μm, the interval between the shielding walls is 20 to 185 μm, and the width, height and interval of the shielding walls may be determined according to the optical linkage therebetween.

The mask may further include a second film layer bonded to the shield layer to reinforce the first film layer, or a third film layer bonded to the first film layer on a surface opposite to the molding surface of the shield layer to reinforce the first film layer.

The protector of the present invention may further comprise a polarizing film laminated directly on the image emitting surface of the protector or arranged in a separated manner by a bonding means.

The first film layer, the second film layer, the third film layer or the polarizing film used in the present invention is made of a material having a material, specification and composition required for manufacturing the protector, and preferably, the protector is made of at least one or more components selected from the group consisting of polypropylene Oxide (polyoxypropylene Oxide), polyurethane (Polyisocynate), hydroxyethyl, polyvinyl chloride (PVC), polyethylene terephthalate (PET), monoacrylate (monoacrylate), polyacrylate, polymethyl methacrylate, polyurethane, Polycarbonate (PC), polyethylene, methacrylate, polypropylene, Cellulose Acetate Butyrate (CAB), Ethylene Vinyl Acetate (EVA), polyvinyl alcohol (PVA), acrylate, propylene Oxide (propyleneoxide), acrylic resin, copolymers thereof, and glass, which have suitable resistance to temperature, deformation, pressure, humidity, discoloration, etc. required for manufacturing the protector. In particular, the fabric having enhanced elasticity due to the polyurethane component can protect the liquid crystal and the screen from the dangers such as external impact and scraping of core structures such as computer monitors, liquid crystals of mobile phones, screens of cash dispensers, glass of buildings and the like which are exposed to damage dangers due to low impact resistance.

The thickness of the film may take various values in the range of 10-2000 μm depending on the width and height of the formed shielding partition walls.

The shielding walls constituting the shielding layer (blade layer) may be overlapped with each other by repeatedly printing or transferring the color ink on the same position of both surfaces of the first film layer, or the shielding walls may be overlapped with each other by joining the shielding layer formed by repeatedly printing or transferring the color ink on one surface or both surfaces of the second film layer with the shielding layer on the first film layer.

The present invention may further include a protective film (Liner) that prevents surface damage of each film constituting the protector.

The color ink forming the shielding partition contains a pigment and a resin, and may optionally include a solvent, a polymerization initiator, a viscosity modifier, an antioxidant, a wetting agent, a dispersant, a polymerization inhibitor, a sensitizer (sensitizer), and the like.

In this case, an organic or inorganic pigment or dye may be used as the pigment, an organic pigment may be used for high-concentration shielding, and an inorganic pigment may be used for low-concentration shielding. In particular, when a pigment having a high concentration and a high absorbance is used in combination with a pigment having a low concentration and a low absorbance, which can prevent random reflection, the image distortion output of the protector can be shielded to provide a clear image. At this time, it is preferable that the particle size of the color ink is about 2nm to 18 μm.

Preferably, the resin may be polypropylene oxide, polyethylene, polypropylene, Ethylene Vinyl Acetate (EVA), polyvinyl alcohol (PVA), polyvinyl chloride (PVC), polyethylene terephthalate (PET), Cellulose Acetate Butyrate (CAB), monoacrylate, polyacrylate, polymethyl methacrylate, polyurethane, polycarbonate, propylene oxide, polyurethane, hydroxyethyl acrylate, hydroxyethyl methacrylate, or a copolymer thereof.

Detailed Description

The embodiments of the present invention will be described in detail with reference to the drawings, and the same reference numerals will be used for the same constituent elements.

As shown in fig. 1a, a protector 1 according to an embodiment of the present invention includes: a first film layer 10; a shielding layer 15 composed of a plurality of shielding partitions 15-1. The shielding partition wall 15-1 is made of light absorbing color ink, and the same pattern is repeatedly printed or transferred at the same position to form the shielding partition wall 15-1 with a height suitable for the purpose.

The protector of the present invention can make the shielding partition wall 15-1 perpendicular to the surface of the first film layer 10 as shown in fig. 1a, or can make the shielding partition wall 15-1 and the surface of the first film layer 10 form a designated angle α as shown in fig. 1b, thereby allowing the object picture to be seen only at the front or at a designated angle set according to the purpose and use and the characteristics of the applicable machine.

The shielding partitions 15-1 may be arranged in parallel in the vertical, horizontal, or diagonal directions at a predetermined separation pitch, or may be arranged in a lattice pattern having a predetermined angle in the vertical, horizontal, or diagonal directions.

In this case, the width, height, and separation pitch of the shielding partition wall 15-1 may be adjusted in conjunction with each other as needed, and various angles other than the above angles may be formed, and a lattice shape and various directions may be formed according to the angles.

For example, as shown in fig. 8, when the shielding partition walls are made to have a width of 10 μm, an interval between the partition walls of 50 μm, and a height of 180 μm, if the shielding partition walls can shield light 100%, a viewing angle of 16 ° can be theoretically possessed. However, when the shielding walls cannot shield light by 100%, a wider viewing angle can be obtained.

The shielding partition walls 15-1 are formed on the surface of the first film layer 10 by a color ink (for example, by combining a color pigment with a transparent UV resin) printing or transfer method, the shielding partition walls 15-1 may be printed or transferred on one side or both sides of the first film layer 10, and the shielding partition walls 15-1 formed on both sides of the first film layer 10 as shown in fig. 1c may be formed at the same position and overlapped with each other to increase the height when the shielding partition walls 15-1 are printed or transferred on both sides of the first film layer 10. When the shielding partition walls are formed on both sides as shown in fig. 1c, the printing height of the shielding layer on each side can be reduced, and thus the shielding layer can be prevented from being damaged while maintaining the protector function when the shielding partition walls are formed in a printing or transferring manner.

The space between the shielding partitions 15-1 printed on one or both sides of the first film layer 10 may be left empty or filled with a transparent substance. When the transparent material is filled, printing or transfer printing can be performed using a transparent film.

The shielding walls 15-1 and 25-1 formed on one or both surfaces of the first film layer 10 or the second film layer 20 are firmly hardened after printing or transfer, and the color ink used in forming the shielding walls can make the shielding walls adhesive, so that lamination can be performed with minimum pressure, and the phenomenon of deformation or damage of the shapes of the shielding walls 15-1 and 25-1 can not occur when the lamination process is performed with other film layers. Further, when transparent pigments (general ink or UV pigment) are printed or transferred between the shielding partitions in the same manner as the shielding partitions to form the transmissive portions 15-2 and 25-2, the deformation of the shielding partitions can be further reduced.

The shield layer molding surface of the first film layer 10 and the other surface may include a second film layer 20, a third film layer 30 or a polarizing film 40 formed in a layered manner by thermal lamination, as shown in fig. 2a, the protector of the present invention may further include a second film layer 20 attached to the shield layer 15 to reinforce the first film layer 10, or may further include an adhesive layer between the shield layer 15 and the second film layer 20 in order to attach the second film layer 20.

According to an embodiment of the present invention, a shielding layer composed of a plurality of shielding partitions may be formed on one surface of each of the first film layer 10 and the second film layer 20 or on each surface of the two film layers, and the shielding partitions 15-1 formed on the first film layer 10 and the shielding partitions 25-1 formed on the second film layer 20 may be overlapped with each other to facilitate printing. At this time, the shielding layer 15 on the first film layer and the shielding layer 25 on the second film layer need to be repeatedly printed or transferred by using the same pattern (see fig. 2 b).

Moreover, the protector of the present invention may further include a third film layer 30 which is adhered to the opposite side of the molding surface of the shielding layer 15 of the first film layer 10 and reinforces the first film layer 10; an adhesive layer may be further included, which is formed between the first film layer 10 and the third film layer 30 for adhering the third film layer 30 (see fig. 2 c).

The protector of the present invention may further include a polarizing film 40 laminated directly on the image emitting surface of the first film 10, the second film 20, or the third film 30, or may be separately disposed by a coupling means 45 (see fig. 2d and 2e), the polarizing film 40 may further diffuse and transmit the image transmitted through the shielding layer, and may further and reliably shield the image without transmitting the shielded image or with less shielding of the shielding partition wall, thereby exerting a polarizing function, and if necessary, the protector may further include other polarizing functions, and further may further combine functions of the polarizing film, such as light reflection and refraction, light linearity, reflection law, total reflection and dispersion of light, light polarization, surface reflection prevention, and non-polarization conversion into linear polarization, etc., as required according to the usage and purpose.

In the process of forming the image display layer 50 that allows only the left, right, top and bottom sides around the protector user to view, the image display layer is formed on any one of the first film layer, the second film layer, the third film layer and the polarizing film layer by using a pigment of a desired color in the same manner as in the printing process for forming the shielding layer, whereby the image display layer 50 is formed so as to be invisible clearly on the top, bottom, left and right sides when the protector is viewed from the front (fig. 2 f).

That is, the image display layer 50 may be formed after printing or transferring an image to be displayed using a pigment of a desired color on one surface of the first film layer 10, the second film layer 20, the third film layer 30, and the polarizing film 40.

For example, in forming the image display layer 50, a transfer layer is formed on the front surface of a fabric (e.g., a paper fabric), and then the transfer layer formed on the fabric is bonded to one of the first film layer 10, the second and third film layers 20 and 30, and the polarizing film layer 40, and then the image display layer 50 is formed on the fabric by applying an appropriate temperature and pressure to the back surface of the fabric using a thermal transfer machine.

Further, if the image display layer is formed on the shielding layer 15, the image display layer may be formed by printing or transferring a portion of the shielding partition in a desired logo or character form using an ink having a color different from that of the shielding film when the shielding partition is printed or transferred on the shielding layer 15. In this case, the front face and the shielding partition of the protector are overlapped and cannot be seen, and the image display layers are displayed on the left, right, upper and lower side faces in accordance with the printed color images.

The shielding layer 15 or 25 of the protector of the present invention is formed by repeatedly arranging shielding partitions for shielding incident images in a parallel or predetermined angle grid pattern at a predetermined separation distance, and the shielding partition 15-1 or 25-1 is formed in parallel in the left-right direction as shown in fig. 3a, and the screen is not visible in the up-down direction of the screen, and the shielding partition 15-1 or 25-1 is formed in parallel in the up-down direction as shown in fig. 3b, and the screen is not visible in the left-right direction. In addition, the parallel shielding partition 15-1 or 25-1 having a designated angle according to its use is formed in order to prevent the visibility at a specific angle such as 45 degrees, 60 degrees, 75 degrees, etc.

Furthermore, the shielding partition walls 15-1 or 25-1 may be arranged in a lattice shape at a predetermined angle. As shown in fig. 3d, a lattice shape with an angle of 90 degrees in the vertical and horizontal directions may be formed, or as shown in fig. 3e, a lattice shape inclined at a predetermined angle may be formed.

If the shielding partition walls 15-1 are printed or transferred in parallel arrangement as shown in FIGS. 3a, 3b and 3c, the image of the display M is not easily visible at a predetermined angle other than the front side as shown in FIG. 5. In addition, when the shielding walls have a lattice shape as shown in fig. 3d and 3e, the image is not easily visible at an angle other than the front as shown in fig. 5.

As described above, the shielding layers 15 and 25 formed on the first film layer 10 or the first and second film layers 10 and 20 allow a clear image to be viewed without blurring or distortion when the image of the display M is viewed from the front, but shield the image by the shielding partition (as shown in fig. 5) when the image of the display M is viewed around the display M, i.e., at an oblique angle above, below, left, and right, thereby preventing the image of the display M from being viewed.

The structure of the present invention described above is further specifically described below.

First, the materials of the first, second, third film layers and the polarizing film required for manufacturing the protector of the present invention are selected from materials having the materials, specifications and components required for manufacturing the protector. In this case, the thickness of the film is usually set in the range of 10 to 2,000 μm, although it varies depending on the purpose and application of the protector, and various thicknesses may be selected as necessary.

Further, it is preferable that the material of the face material of the film is one of polypropylene oxide, polyurethane, hydroxyethyl, polyvinyl chloride (PVC), polyethylene terephthalate (PET), monoacrylate, polyacrylate, polymethyl methacrylate, polyurethane, polycarbonate, polyethylene, methacrylate, polypropylene, Cellulose Acetate Butyrate (CAB), Ethylene Vinyl Acetate (EVA), polyvinyl alcohol (PVA), acrylate, propylene oxide, acrylic resin or their copolymer and glass, which have appropriate resistance values against temperature, deformation, pressure, humidity, discoloration, etc. required when the protector is manufactured.

In addition, the fabrics with elasticity enhanced by the components such as urethane in the fabrics of the first, second, third film layers and the polarizing film can be exposed to dangerous protective liquid crystal screens such as computer monitors, mobile phone liquid crystals, screens of cash dispensers, external impact and scraping of core structures such as glass of buildings and the like which are dangerous to damage due to low impact resistance.

Preferably, the shielding partition 15-1 or 25-1 of the present invention has a high absorbance to ensure sufficient shielding. The shielding partition wall is formed using color ink capable of shielding an image, and may be formed using UV ink or solvent-based ink, but it is preferable to use UV ink for rapid curing.

In addition, the color ink forming the shielding partition wall contains a pigment and a resin. Optionally, a solvent, a polymerization initiator, a viscosity modifier, an antioxidant, a wetting agent, a dispersant, a polymerization inhibitor, a sensitizer, etc. may be contained.

In this case, an organic or inorganic pigment or dye may be used as the pigment, an organic pigment may be used for high-concentration shielding, and an inorganic pigment may be used for low-concentration shielding. Particularly, when a pigment having a high concentration and a high absorbance is mixed with a pigment having a low concentration and a low absorbance for preventing random reflection, the image distortion output of the protector can be shielded to provide a clear image, and the high absorbance pigment or the low absorbance pigment can be selected and used alone or in a mixture according to the use conditions of the product. At this time, it is preferable that the particle size of the color ink is about 2nm to 18 μm.

Preferably, the resin is polypropylene oxide, polyethylene, polypropylene, Ethylene Vinyl Acetate (EVA), polyvinyl alcohol (PVA), polyvinyl chloride (PVC), polyethylene terephthalate (PET), Cellulose Acetate Butyrate (CAB), monoacrylate polyacrylate, polymethyl methacrylate, polyurethane, polycarbonate, propylene oxide, polyurethane, hydroxyethyl acrylate, hydroxyethyl methacrylate, or a copolymer thereof.

The color ink is printed in colors and images designed and set on the patterns during printing, and can be used even when an image display layer is printed, and the image display layer can display various logos, characters, images and the like which are not displayed on the front surface of a protector user but can be clearly seen on the side surface.

In the step of overlapping and bonding the first film layer and the adhesive layer on one or both surfaces of the second film layer, the third film layer or the polarizing film or the protective film for surface protection for preventing the surface of the film from being damaged, it is preferable that the protective film to be used is one selected from PP, PET, OPP and PVC and the surface of the film is coated with PE to have a thickness of 2 to 30 μm to perform a surface isolation (Release) treatment.

If the materials and components of the general materials are used in the coating operation of the main coating substance such as the ink printing for forming the shielding partition wall of the protector, the image ink printing for the image display layer, the adhesive coating for the film lamination, the adhesive agent for the bonding means and the like, the primary coating is not needed; however, if it is necessary to use materials and components having special applications and purposes or materials, the materials may be separated and fall off from the films coated with the pigments and adhesives or adhesive agents used because of the chemical components and characteristics of the materials, and a primary Coating (Primer Coating) step may be performed as a step prior to the primary Coating step in order to prevent separation and fall off and to deposit each Coating material in a fine particle form on the film surface without being affected by the films, Coating material raw materials and types, and chemical component characteristics and materials.
