[Figure 4] FIG. 4 is a diagram showing the luminous sheet and transparent sheet of the present invention pasted together. DETAILED DESCRIPTION OF THE INVENTION
[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
[0018] The phosphorescent display 1 of this embodiment is a phosphorescent display 1 that stores light from a light source, including sunlight, in the phosphorescent layer 30, and utilizes the luminous effect, which is the phosphorescence action, to make the display unit 40 clearly visible even in the dark.
[0019] As shown in Fig. 1 and Fig. 2, which is a cross section taken along the line AA in Fig. 1, this phosphorescent display unit 1 has a second adhesive layer 12 provided on the surface of an ultra-high brightness phosphorescent sheet 60, and a display section 40 formed of a cutting sheet provided on the second adhesive layer 12. Here, the display section 40 displays text such as "Beware of fire! Watch out for mountain fires..." as well as a management number 40a (here, "1") indicating its position on a mountain or the like.
[0020] The ultra-high brightness luminous sheet 60 has a highly flexible sheet-like substrate 20 selected from PVC film, PET film, silicone-coated film, etc., and a first adhesive layer 11 is formed on the back surface 21 of this substrate 20 by applying a highly adhesive acrylic adhesive by spraying, roll coating, or other application method, and a luminous layer 30 made of a sulfide-based luminous paint or oxide-based luminous paint is formed on the front surface 22 of the substrate in a substantially smooth coating.
[0021] In particular, the luminous layer 30 is of ultra-high luminance and has the function of emitting light for more than 12 hours after sunset when excited by sunlight outdoors. Next, the display section 40 formed by the cutting sheet is configured so that the management number 40a and letters and images of the display content are formed in advance using a cutting plotter or laser processing, and a transparent second adhesive layer 12 in the form of a sticker is placed on the back side.
[0022] In the display unit 40 of this embodiment, a light-reflecting cutting sheet is used for the management number 40a and the characters and images to be highlighted.
[0023] Furthermore, a second adhesive layer 12 is provided on the surface of the ultra-high brightness luminous sheet 60, and a transparent sheet 50 is provided on the surface of the display section 40 formed by the cutting sheet, covering the display section 40. As shown in Figures 3 and 4, the transparent sheet 50 may be a glossy film, a matte film, or the like, which is pressed against the display section 40 by a heater bar, platen roller, or pressure-bonding silicone roller 100 of a laminator, and laminated.
[0024] Next, the operation of the device when an ultra-high brightness luminous sheet 60 is used will be explained with reference to FIGS.
[0025] A display unit 40 coated with a second adhesive layer 12 is stably fixed to the surface of a luminous sheet 60 having a first adhesive layer 11 and a luminous layer 30 made of ultra-high brightness luminous paint superimposed on a substrate surface 22 of a substrate 20 made of a PET film. Furthermore, this phosphorescent display 1 is covered with a transparent sheet 50, and then laminated.
[0026] In such a phosphorescent display 1, the display section 40 formed by a cutting sheet is attached to the surface of the phosphorescent sheet 60, which has a phosphorescent layer 30 provided on the entire surface, via the second adhesive layer 12, making it easy to change the characters and images on the display section 40. Furthermore, in such a phosphorescent display unit 1, the non-emitting display section 40 can be seen by the phosphorescent sheet 60 which emits light over its entire surface in the dark. Furthermore, since the luminous sheet 60 is flexible, the luminous display unit 1 can be easily attached to a variety of locations, such as a substantially flat attachment target object such as a signboard or a cylindrical attachment target object such as a sign pole.
[0027] Furthermore, when the phosphorescent display body 1 is exposed to daylight, light is collected in the phosphorescent layer 30 of the phosphorescent display body 1, and in the dark, the phosphorescent layer 30 emits light due to its phosphorescent effect.
[0028] In the daylight state shown in FIG. 1(a), the display unit 40 is normally visible, and in the dark state shown in FIG. 1(b), the display unit 40 is visible even though it is not emitting light, because the luminous layer 30, which has collected light when exposed to daylight, emits light. Such a phosphorescent display 1 is provided with a display section 40 that displays a management number 40a, characters and images, so that the display section 40 can be seen even in the dark, and also, if a person who is lost in the mountains or the like communicates the management number 40a to an outsider, the current location of the person can be identified, which is extremely useful for rescuing the person who is lost.
[0029] 1(c) is a diagram showing a state in which light is shining on the light-reflective display unit 40 in the dark. By replacing the cutting sheet of the display unit 40 with a light-reflective cutting sheet, when the display unit 40 is installed in the dark, such as a parking lot, and car headlights or the like shine on the display unit 40, the display unit 40 appears brighter than the surrounding luminous layer 30.
[0030] 3 and 4, the phosphorescent display unit 1 including the display unit 40 is covered with a transparent sheet 50, and the transparent sheet 50 is pressed against the heater bar, platen roller, and pressure-fitting silicone roller 100 of a laminator to perform a laminating process. The transparent sheet 50 enables the phosphorescent display unit 1 including the laminated display unit 40 to maintain the light collection state when exposed to daylight. The light collected through the transparent sheet 50 is luminous sheet 60, and the luminous effect of the phosphorescent performance of the display unit 40 in the dark can be confirmed. In addition, by laminating the phosphorescent display 1, the display unit 40 is not exposed to the outside air, and furthermore, the transparent sheet 50 located on the surface of the display unit 40 can suppress deterioration over time of the display unit 40, the phosphorescent layer 30, etc. In the above embodiment, a transparent sheet 50 is provided, but this is not necessarily required. Also, the display unit 40 uses a light-reflective cutting sheet, but of course it does not have to be light-reflective, and the light-reflective type may be a part of the entire display unit 40. Furthermore, the display unit 40 is not limited to a cutting sheet. The display unit 40 may be, for example, a transparent sheet on which characters or the like are drawn or printed and attached to the surface of the phosphorescent layer 30. [Explanation of symbols]
