The printed layer 20 on which (21) is formed is attached, so that different display states are implemented according to the observer's gaze.

Display boards installed at various industrial sites such as construction sites are used for various purposes, such as pre-warning of risk factors at the site or inducing evacuation in the event of a disaster such as fire or collapse, so that visibility of the contents of the display is possible. In addition to the need to secure (視認性), various visual signal means such as characters, figures, and pictograms are applied to enable intuitive and quick grasp of the meaning of the display board.

In particular, construction sites have characteristics that not only heavy facilities are built and heavy equipment passes, but also the shape and structure of the site are constantly changing, so the original function of the warning signs and safety guidance signs is very important compared to other industrial sites. I can do it.

As a technology related to the display panel for construction sites, there may be a prefabricated display panel such as Patent No. 1302792, which is a temporary facility, not a permanent facility due to the nature of a construction site that is limited during the construction period in an open-air environment. , The display panel is configured to be easily assembled and dismantled, and the main focus is on storage, transportation, and reuse.

However, as described above, the display panel can be called a danger warning and safety guidance as its intrinsic functions, and such basic functions are particularly required at construction sites. As a result of the conventional assembly type display panel, visibility may be improved or the operator's There were bound to be limits in calling attention.

Accordingly, a display panel such as Patent No. 16 88745, which constitutes a light source on the display panel and supplies power to emit or blink display phrases or symbols, has been developed, thereby enhancing the ultimate purpose of the display panel to improve visibility and alert workers. Although it has been able to achieve a certain level, it is difficult to assemble and disassemble due to the complicated configuration in which a light source and distribution device are installed, and a separate wiring for power supply must be constructed. There was only one, and there was a serious problem that enormous costs were required for production and installation.

In view of the above-described problems, the present invention was devised to ensure the visibility and ventilation performance of the display panel even with a simple configuration, and the transmission layer 10 is formed on the front surface of the printing layer 20. In the display panel to which) is attached, the transmission layer 10 is configured by joining a plurality of transparent columnar bodies 11 in parallel, and each columnar body 11 has an arc-shaped cross-section protruding forward. , A printing line 21 is formed on the printing layer 20 attached to the back surface (裏面) of the transmission layer 10, but the printing line 21 is parallel to the columnar body 11, and the printing line 21 Is formed of a plurality of sets, but the print lines 21 of the same set are arranged at intervals that are multiples of the arrangement intervals of the columnar body 11, so that the print lines 21 of the same set are arranged according to the line of sight of the observer. It is a multi-display panel using lenticular, characterized in that it is displayed.

In addition, an antifouling layer 30 having a smooth outer surface is formed on the front surface of the transmission layer 10, and the antifouling layer 30 is formed of a material having a refractive index different from that of the transmission layer 10. It is a multi-display panel using lenticular.

Through the present invention, it is possible to implement a display panel in which the display state of characters and symbols is changed even with an extremely simple configuration, and thereby, the visibility and attention ventilation function of the display panel can be remarkably improved.

In particular, the function of changing the display state as described above can be achieved by not only omitting all electrical devices such as light sources, but also with a very simple configuration at the same level as general printing paper, convenience of storage, transport, installation and disassembly of the display panel Can be maximized, and production cost can also be reduced.
