Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a display device using EL (electroluminescence).

(Purpose of the invention) An object of the invention is to provide a book-type display device that is capable of displaying a variety of displays and is suitable for restaurant menus and the like.

(Summary of the invention) The invention consists of forming a pocket with a transparent film on each side of a pair of cover materials, and inserting a transparent sheet with a sheet-like EL element and display text written inside the pocket to use it as a cover. , These are combined on the back cover, and an EL drive inverter is installed on the back cover.
While incorporating batteries, switches, etc., a transparent film is formed into a bag and a sheet is placed inside.
This is characterized in that the inner page portion into which a transparent sheet with an EL element and display text written is inserted is closed in such a way that the electrodes of the EL element are connected to the inverter.

(Example) Figures 1 to 9 show an example of the present invention, in which a pair of cover materials (cardboard, wood, leather, etc.) 11, 2
A pocket (the top side is the opening and the other three sides are glued to the cover material) 12, 22 is formed on each side of the sheet of transparent film, and a binding opening 13, 23 is provided in the opening. ing. Inside one pocket 12 is a sheet-like EL element 14 and a transparent sheet (part of the menu) 1 with display characters written on it.
5 is inserted so that the EL element 14 faces the cover material 11 side to form one cover 10. Similarly,
An EL element 24 and a transparent sheet 25 forming a part of the menu are inserted into the other pocket 22 to form the other cover 20.

Both covers 10 and 20 are joined by a spine 30. The back cover 30 has a case 31, inside which a battery 32 as a power source, an inverter 33 for driving the EL element, an electrode connection part 34, and a power switch 3 are installed.
5. It incorporates a switch 36 that turns on and off in conjunction with the opening and closing of the cover, and when connected to the covers 10 and 20 by the cover attachment part 37, the electrode connection part 3
4, the electrode terminals 14A of the EL elements 14, 24;
24A is connected. In addition, 38 is a battery exchange port,
39 is an internal page attachment part.

In addition, the inner page portion 40 has a bag 41 formed from a transparent film, a binding opening 42 provided at the opening thereof, and a sheet-like EL element 43 that emits light on one or both sides and display characters written inside. A transparent sheet 44 is inserted, and the electrode terminal 43A of the EL element 43 is closed so as to be connected to the electrode connection part 34 of the spine 30, and the internal page attachment part 3 is closed.
Attach to 9.

In the display device having the above configuration, when the power switch 35 is turned on and the covers 10 and 20 are opened, each EL element 14,
24, 43 are in a light emitting state, and the transparent sheets 15,
At 25 and 44, handwritten, photocopied, etc. characters are displayed. This display shows the EL emission color,
The light emitting pattern can be expressed in a variety of ways by combining the color, shape, display characters, pictures, photographs, etc. of the light-transmitting sheet. Therefore, the visual effect is enhanced and it is particularly suitable for use in places where mood is important.

In addition, in the above description, the menu was mentioned as the object to be used, but it can also be used for picture books and the like.

(Effects) As described above, according to the present invention, a pocket is formed on one side of each of a pair of cover materials using a transparent film, and a transparent sheet with an EL element and letters written on it is inserted inside the pocket, and these pockets are inserted into the pocket. The cover is joined via the spine, and the battery and EL are attached to this spine.
While incorporating inverters and switches for driving the elements, the EL is placed in a bag made of transparent film.
Since the inner page portion into which the transparent sheet with the elements and characters written is inserted is inserted between the covers, it is possible to use the inner surface of the cover and the inner page portions as display surfaces to display a variety of displays. Become. Moreover, since it is book-shaped (file-shaped), the visual effect can be enhanced by selecting the transparent sheet or EL luminescent color.
It is effective if used as a menu in a restaurant, etc.
