  According to the present invention, it is possible to enhance fun and design while protecting a display such as a mobile phone.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows a wallpaper image distribution system 1 according to an embodiment of the present invention. The wallpaper image distribution system 1 includes a wallpaper distribution server 2, a mobile phone 3, a public communication line 4, a protective film 5, and a product package 6. The public communication line 4 is an Internet network, for example, and connects the mobile phone 3 and the wallpaper distribution server 2 in a wired or wireless environment. The protective film 5 is attached to the display 3A of the mobile phone 3 and has a function of protecting the display 3A.

  As shown in an enlarged view in FIG. 2, the product package 6 includes a mount 60 and a plastic cover 62, and the protective film 5 is accommodated in an internal space formed by these. The product package 6 and the protective film 5 are arranged in the store in this state and sold as a product. In addition, URL information 64 accessible to the wallpaper distribution server 2 is printed on the mount 60, and a predetermined wallpaper image is downloaded by communicating with the wallpaper distribution server 2 via the public communication line 4 by the mobile phone 3. It is possible. Although the URL information 64 is printed here, the URL information may be described as barcode information. In addition to the address information for the WWW server, it is also preferable to enable downloading by communication via e-mail using an e-mail address or the like. For example, when a mail is delivered from the mobile phone 3 to a specific mail address, it is possible to automatically send an email back to the mobile phone 3 and attach a wallpaper image to the email. .

  As shown in FIG. 3 in an enlarged manner, the protective film 5 includes a protective base layer 50 made of a transparent resin film, an adhesive layer 52 formed on the back side (display side) of the protective base layer 50, A light reflection layer 54 formed on the surface side of the protective base material layer 50 and a print layer 56 formed on the surface side of the light reflection layer 54 are provided. The protective base material layer 50 has a function of protecting the display 3A, but as a material, a polyolefin type such as polyethylene or polypropylene, a polyester type such as polystyrene, polyethylene terephthalate, or polyethylene isophthalate, an acrylic type, nylon, In addition to synthetic resin materials such as homopolymers or copolymers such as polyvinyl chloride, ethylene vinyl alcohol copolymer, polyvinyl alcohol, and polyvinylidene chloride, various materials such as glass and metal foil can be used. Here, it is desirable to use a transparent resin having light transmittance.

  The adhesive layer 52 has a function of adhering the protective film 5 to the display 3A. As a material of the adhesive layer 52, for example, a rubber adhesive such as urethane, silicon, acrylic, or the like can be used. In particular, an adhesive capable of easily peeling off the protective film 5 at any time is preferable, and it is considered that the adhesive does not remain on the display 3A even after peeling.

  The light reflection layer 54 is intended to enhance the light reflection characteristics of the protective film 5 and is formed of a metal thin film such as aluminum or silver. As a thin film forming technique, vacuum deposition, sputtering, ion plating, or the like can be used. Further, by performing the thin film processing, the light reflection layer 54 also has a light transmission characteristic, so that light from the display 3A is transmitted. As a result, when the display on the display 3A is OFF, the protective film 5 reflects extraneous light, and only the reflected light enters the eyes of the user, so that the protective film 5 functions like a mirror.

  Further, when the display 3A is viewed from a substantially vertical direction as indicated by the line of sight X, and the display 3A is turned on, the display 3A that transmits the protective film 3A is compared with the reflected light (arrow P). Since the light (arrow Q) is strong, the user can visually recognize the display on the display 3A without a sense of incongruity. Further, for a person who looks at the display 3A obliquely like the line of sight Y, the light of the display 3A (arrow Q) is weakened according to the angle, while the reflected light (arrow) is increased due to an increase in film pressure of the metal thin film in the line of sight Since P) becomes stronger, it becomes difficult to visually recognize the light (arrow P) on the display 3A. Accordingly, even when another person looks into the display 3A from the side, the display contents cannot be grasped, and thus the privacy of the user can be protected.

  A color print image 100 is printed on the print layer 56 formed on the outermost surface as shown in FIG. In particular, the color print image 100 is four-color printing by combining (combining) four-color raw materials, and is considered to be positioned in the light emitting region H of the display 3A in a state of being attached. As shown in the partially enlarged circle K in FIG. 4, this color printed image 100 is formed by closely arranging fine dot (point) images D, and the group of these is viewed as a whole. As a result, the color print image 100 is configured.

  Therefore, as shown in FIG. 5, each fine dot image D is extremely small and set to a size that the user can hardly recognize, but as shown by the line of sight X, other than the fine dot image D ( The transmitted light (arrow Q) of the display 3A can pass from the surrounding space. Therefore, the image of the display 3A behind the color print image 100 can also be visually recognized. When the display 3A is in the OFF state, only the color print image 100 is visible to the user. As described above, when the display 3A is OFF, the light reflection layer 54 functions like a mirror and can maintain high luminance, and the color printed image 100 is vividly displayed due to the influence.

Further, since this fine dot image D is formed three-dimensionally (three-dimensionally) depending on the ink application thickness, a person who looks at the protective film 5 from an oblique direction, such as the line of sight Y, has the light (arrow) of the display 3A. Since Q) is blocked by the fine dot image D, it becomes difficult to visually recognize the light. As a result, the print layer 56 itself also has a function of protecting privacy. Therefore, it can be said that it is desirable to form the printing layer 56 in the light emitting region H of the display 3A and actively utilize it for privacy protection while improving the design.

  As shown in FIG. 6, the wallpaper distribution server 2 stores the wallpaper image data 24 for the mobile phone 3 and the wallpaper image data 24 in response to a request from the mobile phone 3. A WWW server unit 22 that can be distributed to the mobile phone 3 is provided. Note that, when the wallpaper image data 24 is distributed to the mobile phone 3 by the attached file of the e-mail, it is desirable to install a mail distribution server application having an SMTP function.

  When the URL information 64 displayed on the package 6 is input to the net browser of the mobile phone 3 and the wallpaper distribution server 2 is accessed via the public communication line 4 such as the Internet, the WWW server unit 22 in the wallpaper distribution server 2 The user knows the design type of the protective film 4 purchased by the user. The identification of the design type is realized by assigning an ID for each design of the color print image 100 of the protective film 4 and including the ID in the URL information 64. The WWW server unit 22 extracts the wallpaper image data 24 corresponding to the ID included in the accessed URL information 64 from the wallpaper image database unit 20 and distributes it to the mobile phone 3. The user sets the received wallpaper image data 24 as the wallpaper of the display 3A, and the operation is completed.

  As a result, as shown in FIG. 7, it becomes possible to combine the design A of the protective film 4 and the design B of the wallpaper image data 24 on the display 3A of the mobile phone 3, and an analog color print image 100 is obtained. And the wallpaper image data 24 of digital data can be fused to entertain the user.

  As described above, in the present embodiment, the case where the printing layer 56 is formed on the outermost surface has been described. However, in order to prevent the fine dot image D from being peeled off from the printing layer 56, a protective layer may be further formed on the upper layer. I do not care. Further, the printing layer 56 may be formed on the back side of the protective base material layer 50, and the adhesive layer may be further formed on the back side. Moreover, although the case where the light reflection layer 54 is formed on the front surface side of the protective base material layer 50 is shown here, the present invention is not limited thereto, and may be formed on the back surface side. The light reflecting layer 54 is formed to impart a light reflecting function to the protective base material layer 50, and can be considered as a part of the protective base material layer 50. As the gist of the present invention, it is sufficient if the protective base material layer 50 can have the light reflection characteristic and the light transmission characteristic, and it does not matter whether it is inside or outside the protective base material layer 50.

  Further, in the present embodiment, as shown in FIG. 4, the case where the color print image 100 is configured by a set of fine dot images D is shown, but the present invention is not limited thereto. For example, as shown in FIG. 8, a color print image 100 may be formed by printing a set of parallel fine linear images S. In this way, the light other than the linear image S allows the display light to pass through the printed image. On the other hand, when the protective film 5 is viewed obliquely, the display image is visually recognized by the ink thickness of the linear image S. And it is possible to protect privacy.

  Furthermore, you may make it have a deflection | deviation characteristic as a protective base material layer. In terms of protecting privacy, a film having a deflection characteristic that narrows the viewing angle of the display is used. Although a mobile phone is shown here as a mobile terminal, the present invention is not limited to this. For example, the present invention can be applied to a PDA or the like that does not have a telephone function but has an e-mail, a schedule management function, and the like.

  In the above embodiment, the portable terminal is mainly described as the terminal device, but it can also be used for a display of a personal computer.

  The present invention can be used in industries for protecting various displays such as portable terminals.
