This blind film is not for peeping prevention on the entire surface, but has a “non-restricted band” (0105) which is a band-shaped area that does not limit the viewing angle. The “bar code” (0102) displayed under this non-restricted band is read by the “bar code reader” (0104) without receiving interference from louvers or lattices for preventing peeping. Can do.
<Configuration>

  Blind films for various terminals such as tablet terminals, smartphones, and PC terminals according to the present embodiment are a band-shaped viewing angle non-limiting area, a non-limiting band, and a viewing angle limiting area divided and arranged in the non-limiting band Are provided in the planned layout areas on various terminal screens such as tablet terminals, smartphones, and PC terminals.

  The blind film of this embodiment is arrange | positioned by sticking etc. on the display screen of various terminals, such as a tablet terminal, a smart phone, and a PC terminal. A tablet terminal, a smartphone, and a PC terminal are representative devices that perform information processing using a built-in computer, and since any terminal has a display screen, the blind film of this embodiment is arranged. It is explicitly listed as a target. Therefore, various terminals include mobile phones, game machines, navigation devices, and the like in addition to these representative devices. A “smart phone” refers to a high-function mobile phone having a touch panel as a main user interface device.

  FIG. 2 is a conceptual diagram showing an example of the blind film of the present embodiment. 2A is a plan view showing an example of a blind film, FIG. 2B is a cross-sectional view showing an example of a viewing angle restricted region, and FIG. 2C is an unrestricted band. It is sectional drawing which shows an example.

  As shown in the figure, “blind film” (0201) displays “unrestricted band” (0202) and “viewing angle restricted region” (0203) on the display screen of various terminals such as tablet terminals, smartphones, and PC terminals. It is stored in “Terminal screen layout planned area” (0204).

  The said terminal screen arrangement | positioning plan area | region is an area | region planned to be arrange | positioned on the display screen of various terminal devices among all the areas | domains of a blind film. This region may be appropriately determined according to the screen size of the terminal device on which the blind film is scheduled to be placed.

  The “unrestricted band” (0202) is a band-shaped viewing angle unrestricted region. The unrestricted zone is an area where the viewing angle is limited to prevent peeping. That is, it is formed of a light transmissive material. As shown in FIG. 2B, the “unrestricted band” (0202) has a multi-layer structure, the “adhesive layer” (0205) for bonding to the display screen of a terminal device such as a smartphone, and the most surface layer. A “protective layer” (0206) for protecting the surface of the blind film and a transparent layer described later, and a “transmissive layer” (0208) disposed between the adhesive layer and the protective layer. . The width of the unrestricted band may be at least several mm, for example, about 2 mm.

  Each layer constituting the unrestricted band can be formed of a light-transmitting synthetic resin or the like. For example, it can be formed of polycarbonate resin, polyolefin resin, polyester resin, acrylic resin, or the like. For example, a silicone adhesive, an epoxy adhesive, a urethane adhesive, or the like can be used as the adhesive for forming the adhesive layer or bonding the layers. The configuration and material of the unrestricted band are not limited to those described above, and can be appropriately selected according to known or known techniques.

  The “viewing angle limited region” (0203) is divided and arranged in an unrestricted band. As shown in FIG. 2A, the viewing angle limited region is arranged by being divided into two in the vertical direction by an unrestricted band. As shown in FIG. 2 (c), the viewing angle restricted region has a multilayer structure like the non-restricted zone, and has “adhesive layer” (0205) and “protective layer” (0206). Each layer is integrally formed with an adhesive layer and a protective layer constituting an unrestricted band.

  Between the protective layer and the adhesive layer, a light transmissive “transmissive layer” (0208) in which a “strip-shaped body” (0207) serving as a louver for preventing peeping is disposed. The band-like body is formed of, for example, a colored resin, and restricts the viewing angle by preventing or disturbing light emission by the display screen and diffusion of reflected light reflected by the display screen. The extent to which the viewing angle is limited is determined by the height of the strip and the interval between adjacent strips. The extent to which the viewing angle is limited is appropriately determined according to the specifications of the blind film.

  In addition, you may form with what kind of material outside the arrangement | positioning plan area | region on a terminal screen. For example, it may be formed in the same manner as the viewing angle limited region, may be formed in the same manner as the non-restricted band, or may be formed only by the adhesive layer.

  The technical significance of providing such an unrestricted zone is as follows. The barcode is composed of black bars and white spaces arranged in the horizontal direction. The area occupied by such a barcode is a horizontally long rectangle. In order to read a bar code, it is necessary to irradiate light and receive reflected light from all the bars and spaces arranged in the horizontal direction. This is because the information to be indicated by the barcode is read based on the contrast of the reflected light by the black bar and the white space.

  Here, when the smartphone is displayed on the vertical screen as shown in FIGS. 1 and 2, the unrestricted band crosses the display screen. Applications that display barcodes are usually displayed so that the barcode fits in the horizontal width of the display screen, so display the barcode in the screen area where the unrestricted band is placed. Thus, at least in the horizontal direction, all the bars and spaces constituting the barcode are displayed. Therefore, since the reflected light from all the bars and spaces can be received, reading by a barcode reader becomes possible.

  Further, as described above, since the reading of the barcode depends on the horizontal direction of the bar and the space, the reading can be performed even when all the vertical directions of the bar and the space are not displayed. Although it depends on the bar code standard, the bar and space can be read if they are displayed about 2 mm to 3 mm in height. Therefore, by arranging the non-restricted band with the minimum necessary band width, it is possible to display the barcode in a readable manner with almost no loss of the effect of preventing peeping.

  So far, the blind film in which only one unrestricted band is arranged has been described. However, the number of unrestricted bands is not limited to one, and a plurality of unrestricted bands may be arranged. That is, the non-restricted band includes one in which two or more non-restricted bands are arranged in parallel. FIG. 3 is a conceptual diagram showing a blind film in which two or more unrestricted bands are arranged in parallel.

As shown in FIG. 3A, in the “blind film” (0301), two “unrestricted bands” (0302 and 0303) are arranged in parallel, and the “viewing angle limited region” (0304) is non-restricted. Divided and placed in a restricted zone. In addition, as shown in FIG. 3B, three “unrestricted bands” (0302, 0303, 0304) are arranged in parallel in the longitudinal direction of the “blind film” (0301), and the “viewing angle limited region” ( 0305) may be divided and arranged in each non-restricted band. Such a blind film is useful when two barcodes are displayed vertically on the screen.
<Effect>

The blind film for various terminals such as the tablet terminal, the smartphone, and the PC terminal of the present embodiment can provide a blind film that does not prevent reading of the displayed barcode while preventing peeping.
