BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electro-optical display device in which light-emitting elements such as light-emitting diodes are arranged in a matrix to display information such as characters and figures.

[0002]

2. Description of the Related Art Conventionally, in an electro-optical display device in which light-emitting elements such as light-emitting diodes are arranged in a matrix to display information such as characters and figures, an external factor (rain,
For protection from wind, light, etc.), a resin cover plate is mounted in front of the display surface.

[0003]

Therefore, when the display device is formed in a cylindrical shape and the display contents are scrolled on the display surface so that the display contents can be visually recognized from the entire circumference, a cover plate formed into a cylindrical shape by a mold. Alternatively, it is necessary to use one in which both ends of one flat resin cover plate are bonded or welded to form a cylindrical shape. However, molding by a mold alone is very expensive, and furthermore, it is necessary to manufacture molds corresponding to various display device sizes. Further, in the case of a single plate, it is inexpensive and can be adapted to various sizes, but a seam is formed, and only the seam portion is inferior in visibility.

An object of the present invention is to provide an electronic display device which can solve the above-mentioned problems.

[0005]

According to the present invention, in order to achieve the above object, a light-emitting element such as a light-emitting diode is arranged in a matrix and a display body for displaying information such as characters and figures is formed in a cylindrical shape. In the display device, a transparent resin covering plate provided in front of the display surface is provided, and the seam of the covering plate coincides with the start and end positions of the display information.

[0006]

According to the present invention, it is possible to avoid inferior visibility occurring at the joint portion, and to scroll the display content on the cylindrical display surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a longitudinal sectional view showing an embodiment of the electronic display device of the present invention, and FIG. 2 is a transverse sectional view of the same device. Reference numeral 1 denotes a cover plate formed by processing a single sheet of transparent resin such as acrylic resin into a cylindrical shape, and bonding or welding both ends, a so-called seam 2, to protect the inside from external factors. , 3
Reference numerals a and 3b denote disk-shaped lids whose ends are bent into an L-shape in the entire circumference, and a plurality of support plates 4 having an L-shaped cross-section bent in the center direction are arranged at equal intervals inside the lid. The cover plate 1 is attached with a gap in which the cover plate 1 can be inserted, and sandwiches the upper and lower peripheral edges of the cover plate 1.

Reference numeral 5 denotes a display for displaying information such as characters and figures by arranging light-emitting elements such as light-emitting diodes in a matrix in a cylindrical shape. A plurality of U-shaped frames are provided at equal intervals so as to hold the display body 5 on the outer surface, and lids 3a and 3b are attached in parallel to the upper and lower bottoms of the frame 6, respectively. This is for forming a cylindrical shape firmly with the plate 1 included.

Further, reference numeral 7 denotes lighting of the light emitting element of the display body 5,
It is a control device for controlling the turning off and is located at the center of the main body.
Attached to.

By the way, as shown in FIG. 3, when the display of the cylindrical display device is scroll-displayed one after another such as ABC so that the display can be read from any direction around the display, the display start position 8 (the end position is the same). ) Is required at one place. Therefore, when assembling the cover plate, the seam 2 is assembled so as to coincide with the position 8.

Next, the operation and usage will be described.

The installer stores the display contents in the control device 7 in advance, and provides a leg 9 at the lower part of the display device main body as shown in FIG. No, but a chain etc. is provided on the upper part of the main body so that it can be suspended, and it can be suspended from the ceiling,
Installed in a lobby or other place where people often gather.

The display receiving the signal from the control device 7 turns on and off each light emitting element. As a result, when viewed from the people around the display device, the information is displayed on the display body 5 as information such as characters. At this time, if the information is scrolled sequentially at an appropriate speed, new information appears and disappears from left to right (or right to left) one after another when viewed from a certain place around the display device. .

The display is performed as described above. Even if the user scrolls the display near the seam 2 of the cover 1, the seam 2 and the display start position 8 (the end position is the same) And the display is not originally performed at that portion, so that it is not difficult to read the display, and the display can be read from any position around the display device.

[0016]

As described above, the present invention relates to an electro-optical display device in which light-emitting elements such as light-emitting diodes are arranged in a matrix and a display body for displaying information such as characters and figures is formed in a cylindrical shape. By providing a see-through resin cover plate provided on the other side, and matching the start and end positions of the seam of the cover plate and the display information, the manufacturing cost is low, and the poor visibility generated at the seam portion is reduced. It is possible to avoid such a problem, and the display content can be scrolled on the cylindrical display surface, and the display content can be read evenly over the entire circumference.
