Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a filter to be attached to a display of a mobile phone or the like to prevent peeping.

[0002]

[Prior art]

 In the Japanese Patent Application No. 2001-2460 (Japanese Utility Model No. 3081299), the present applicant laminated and fixed a transparent protective sheet on the surface of a light guide film in which transparent bands and light-shielding bands made of silicon rubber were alternately arranged. The company proposes a filter with a mirror-finished backside of the film, which can be attached to the display.

[0003] If this filter is attached to the surface of the display by the adhesive force of silicone rubber, it can prevent peeping from the side, and since no adhesive tape is used for attaching to the display, This has the advantage that it can be re-attached any number of times.

[0004]

[Problems to be solved by the invention]

 However, such a filter, when mounted on the display of a mobile phone, only shields light when viewed from the side, has little visual change, and is not interesting as a mobile phone accessory. ing.

[0005] In view of this, the present invention aims to provide a display filter that prevents peeping from the side and that allows the display of symbols and characters to be displayed from the side depending on the situation of surrounding light rays.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, this invention is based on a light-guiding film in which transparent bands and light-shielding bands made of silicon rubber are alternately arranged, and a transparent protective sheet is laminated and fixed on the surface of the light-guiding film. In a filter that affixes the back surface to the surface of the display and prevents peeping from the side, using a transparent fluorescent paint that emits light when irradiated with black light that irradiates near ultraviolet light on the surface of the protective sheet, The decorations of the designs and characters were printed.

When such a filter is attached to a display, the display on the screen can be seen from the front side, the display on the screen cannot be seen from the side, and when the light of black light shines, Only the drawn patterns and characters appear to rise.

[0008] Furthermore, when a decorative display of a pattern or a character is printed by using a transparent luminous paint that stores irradiated light and emits light in the dark in place of the fluorescent paint, when viewed from the side in the dark, Only the characters appear to rise.

[0009] In addition, instead of the fluorescent paint, when a decorative display of a pattern or a character is printed using a transparent coloring paint that is colored when exposed to natural light, it can be viewed from the side outdoors or under normal illumination light. , Only the designs and characters appear to be colored.

[0010]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The filter F according to the present invention has a structure in which a protective sheet 2 is laminated and fixed on the surface of a light guide film 1 as shown in FIG. The light guide film 1 is formed by alternately arranging transparent bands 3 and light-shielding bands 4 made of silicon rubber. The back surface of the light guide film 1 serving as an attachment surface has a mirror-finished surface for smoothing irregularities. It has been subjected. The protective sheet 2 is made of transparent polycarbonate.

A decorative display 5 is printed on the surface of the protective sheet 2 using a transparent fluorescent paint that emits light when irradiated with black light. As the decoration display 5, in addition to the design, characters may be drawn for those distributed as promotional items.

In such a filter F, as shown in FIG. 2, the viewing angle θ is limited to a certain range, and since the decorative display 5 is transparent, light is not transmitted within the range of the viewing angle θ. Transience is secured.

As shown in FIG. 3, the filter F as described above is attached to the display of the mobile phone P, and when viewed from the front side, the display on the screen can be viewed as it is. In this state, even if the decorative display 5 is illuminated by the light of the black light, the display is not disturbed because the illumination of the display is brighter.

On the other hand, as shown in FIG. 4, when viewed from the side of the mobile phone P, the display on the screen is not visible due to the obstruction of the filter F, and the peeping of the display contents on the screen is prevented. Then, in this state, when the decorative display 5 is illuminated by the light of the black light, only the designs and characters appear to be raised.

When a pattern or a character of the decorative display 5 is printed using a transparent luminous paint that stores irradiated light and emits light in the dark in place of the fluorescent paint, when viewed from the side in the dark, Only the patterns and letters appear to be raised.

[0017] In addition, instead of the fluorescent paint, when a pattern or character of the decorative display 5 is printed using a transparent coloring paint which is colored when exposed to natural light, it can be viewed from the side outdoors or under normal illumination light. , Only the designs and characters appear to be colored.

[0018]

[Effect of the invention]

 As described above, in the present invention, decorations of symbols and characters were printed using a transparent fluorescent paint that emits light when illuminated by black light on a filter that prevents peeping from the side. On the front side, the display on the screen can be seen as it is, from the side, the display on the screen cannot be seen, and when illuminated by black light, only the designs and characters drawn on the surface appear to rise.

When a decorative display of a pattern or a character is printed by using a transparent luminous paint that stores irradiated light and emits light in the dark instead of the fluorescent paint, the pattern and the character are viewed from the side in the dark. Only the characters appear to rise.

[0020] In addition, instead of the fluorescent paint, when a decorative display of a pattern or a character is printed using a transparent coloring paint which is colored when exposed to natural light, it can be viewed from the side outdoors or under normal illumination light. , Only the designs and characters appear to be colored.

Therefore, such a filter as described above is expected to have an effect of attracting the interest of a young person or the like as an accessory of a mobile phone.
