Detailed Description
Hereinafter, a method for manufacturing a mobile phone decoration film using a UV patterning type microlens array according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, in the drawings, the same constituent elements or components are illustrated by the same reference numerals as much as possible. In describing the present invention, a detailed description of related well-known functions or configurations will be omitted so as not to obscure the gist of the present invention.
Fig. 1 is a schematic view of a microlens array layer according to an embodiment, and fig. 3 is a schematic view of a mobile phone decoration film formed with a microlens array layer according to an embodiment.
The mobile phone decoration film 100 may include a Polycarbonate (PC) layer 110 and a Micro Lens Array (MLA) layer 120 formed in a UV-patterned manner on a front surface of the PC layer 110 as a thin film applied to a rear cover formed on a rear surface of a mobile phone.
The polycarbonate layer 110 as the base film is a thermoplastic plastic. Has the characteristics of impact resistance, heat resistance, weather resistance, self-extinguishing property, transparency and the like, and has the impact strength which is about 150 times or more of that of toughened glass, thereby having excellent flexibility and processability. As a substitute material for acrylic which is easily broken and easily deformed, and a material for use as a backup material for general plate glass, they are widely used.
The microlens array layer 120 according to an embodiment may be formed of at least one of epoxy resin, acrylic resin, polyolefin resin, polyamide resin, polyester resin, polyvinyl chloride resin, polyvinyl acetate resin, petroleum resin, phenol resin, polystyrene resin, and polyurethane resin as a thin film layer formed in a UV patterning manner.
In addition, the microlens array layer 120 may be formed in front of the polycarbonate layer 110 by a gravure process using a gravure roll formed with a predetermined pattern or shape of intaglio grooves.
For the microlens array layer 120, after the composition is filled in the intaglio groove, the cross section may have a concavo-convex shape as the intaglio printing is performed on the front surface of the microlens array layer.
The adhesive according to an embodiment may use a resin material having a predetermined viscosity. Since a viscous substance is used, the adhesion force between the film, the pattern layer or the metal decorative layer can be improved without providing a separate adhesive layer. The adhesive may include at least one of an epoxy resin, an acrylic resin, a polyolefin resin, a polyamide resin, a polyester resin, a polyvinyl chloride resin, a polyvinyl acetate resin, a petroleum resin, a phenol resin, a polystyrene resin, and a polyurethane resin.
In addition, the microlens array layer is a pattern (pattern) printed layer in which MLA is formed by UV molding on the whole of the front surface of the polycarbonate layer, and in this case, the pattern (pattern) may be printed based on an ultraviolet-ray Printing (Ultra-Violet Printing) method.
The UV printing method is a method for improving such a technical problem, in which a dedicated liquid ink having an instant drying property, which is instantly cured while being exposed to UV light, is used, and is instantly dried by ultraviolet rays, so that various colors can be embodied without being limited by materials, and has strong anti-discoloration and anti-moisture properties, thereby ensuring excellent durability based on external climate change.
Even if the pattern layer is not a UV type pattern layer, the pattern layer may be formed by a gravure printing process using a gravure roll having a surface formed with a predetermined pattern or shape of a gravure groove. At this time, after the composition for forming the UV pattern layer is filled in the intaglio groove, the pattern layer having the uneven shape in cross section can be formed as the intaglio printing is performed on the color print layer. As described above, when the UV pattern layer is formed, various designs can be exhibited, so that the aesthetic sense can be improved.
The composition for forming the pattern layer may contain a viscous substance. The adhesive substance may include at least one of epoxy resin, acrylic resin, polyolefin resin, polyamide resin, polyester resin, polyvinyl chloride resin, polyvinyl acetate resin, petroleum resin, phenol resin, polystyrene resin, and polyurethane resin. The composition for forming a pattern layer containing a viscous substance is filled into a gravure roll having a surface on which a gravure groove is formed, thereby allowing a gravure printing process to be performed. Therefore, the pattern layer can be formed immediately without additional curing process in the subsequent process, thereby simplifying the process and shortening the process time.
In the UV pattern layer formed in front of the polycarbonate layer 110, if the composition forming the UV pattern layer contains the same adhesive material as that used in the colored print layer, the interfacial characteristics between the colored print layer and the UV pattern layer can be improved.
The UV pattern layer 130 is formed on the back surface of the polycarbonate layer, and may be formed with various patterns (patterns) as is well known in the art.
Next, a step of forming a deposition layer 140 corresponding to the pattern of the UV pattern layer 130 on the back of the UV pattern layer 130 is included. The Deposition layer 140 is formed of a material having a predetermined transmittance, and may be formed based on Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), or the like.
In addition, the transmittance or reflectance may be adjusted while maintaining the pattern formed on the UV pattern layer 130. The deposition layer 140 may include at least one of indium, chromium, Tin, and ito (indium Tin oxide) as a transparent conductive layer having conductivity.
Chemical vapor deposition, which utilizes chemical reactions during the fabrication process, is a process technique for forming a silicon thin film or the like on a substrate in the fabrication process of an integrated circuit or the like. Is widely used for manufacturing Silicon oxide films, Silicon nitride films, Amorphous Silicon (Amorphous Silicon) films, and the like. When a gas containing a chemical substance is plasmatized by applying thermal energy or optical energy or by high frequency, the raw material is atomized to greatly improve the reactivity, and adsorbed and deposited on the substrate.
The physical vapor deposition process is a process of depositing an oxide semiconductor, GaAs, or the like on a substrate by melting a compound substance to prepare a target substance in a solid state, volatilizing the target substance by heat or an electron beam, and depositing the target substance on the substrate.
At this time, the raw material is volatilized in a gaseous state by heat, laser, electron beam, or the like, and the volatilized gaseous raw material becomes a solid state when contacting the substrate.
Next, a step of forming a screen printing layer 150 on the rear surface of the deposition layer 140 is included. The screen printing layer 150 is formed by a screen printing method, and may also print a logo, a product model name, a button, or a specific pattern.
Secondly, a forming operation step of 3D die stamping is performed after screen printing to provide a stereoscopic aesthetic feeling.
Next, a CNC processing step of cutting the molded cellular phone decorating film 100 into individual cells (cells) is performed.
Fig. 2 is a schematic diagram illustrating a mobile phone decoration film portion formed with a microlens array layer 120 applied to a mobile phone case 200, the mobile phone case 200 can be clearly distinguished into a portion 220 applied with the mobile phone decoration film 100 and a portion 210 not applied with the mobile phone decoration film, and the applied portion 220 can be visually seen as a hazy feeling.
That is, the present invention can provide various aesthetic feelings to a user by generating a hazy feeling visually through the microlens array layer as compared with a conventional decoration film applied to a rear cover, and can ensure a high recognition state by improving scratch resistance, chemical resistance, and durability as compared with a conventional film and by not leaving any trace such as a fingerprint.
