[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device using a light emitting diode, and more particularly to a display device suitable for being installed at an entrance door of a game hall such as a pachinko hall, a store, a restaurant, a department store or the like. .

[0002]

2. Description of the Related Art Conventionally, for example, a display device in which a large number of light emitting diodes are arranged in a dot matrix on a wiring board and the light emitting diodes are made to blink according to a command from a control circuit to display arbitrary characters, designs, etc. Are known.

[0003]

However, the conventional display devices using a large number of the above-mentioned light emitting diodes are uniform, have no novelty, and have a limited display effect.

[0004]

DISCLOSURE OF THE INVENTION The display device of the present invention is intended to solve the above-mentioned problems, and a thin thin film sheet made up of a plurality of light emitting diodes is mounted on a transparent thin film sheet so that the front can be seen through. It is arranged in a mesh shape, and the large number of display bodies are made to blink in accordance with a command from the control circuit to display arbitrary characters, patterns and the like.

[0005]

In the present invention, it is possible to display an eye-catching display such as arbitrary characters and designs simply by attaching it to the entrance door, and since the front can be seen through, the outside can be seen from the inside of the entrance door. A new display effect can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a schematic side view showing a state in which a display device according to an embodiment of the present invention is attached to an entrance door of a pachinko hall, and FIG. 2 is a front view near the entrance door.

In the figure, reference numeral 1 is a lateral slide type entrance door made of thick plate glass provided in a store of a pachinko hall, and the entrance door 1 is automatically slid to the left and right when a person approaches. . Reference numerals 2 and 3 denote infrared ray-sensing sensors that are provided downward on the outer wall and the inner wall of the upper wall surface 4 of the entrance door 1 to detect the approach of a person. Reference numeral 5 indicates a pachinko machine provided in the store.

Reference numeral 6 denotes a display device of this embodiment arranged on the outer surface of the entrance door 1. The display device 6 is
As shown in FIGS. 3 and 4, a transparent resin thin film sheet 8 provided with a printed wiring 7, a large number of thin plate-shaped display bodies 9 arranged in a fine mesh, and circuits constituting a control circuit. The substrate 10 and the substrate 10 are generally configured.

In the present embodiment, the display body 9 is a combination of a light emitting diode (LED) 11 that emits red color and a light emitting diode (LED) 12 that emits green color, and the printed wiring 7 is combined.
The printed wiring 7 is connected to each of the light emitting diodes 11 and 12 by a gold wire 13 and the entire surface is molded with an epoxy resin 14. The large number of display bodies 9 are arranged on the printed wiring 7 in a fine mesh pattern. The circuit board 10 is a thin film sheet 8
It is housed in a box-shaped portion formed at the lower edge of the.

A terminal 16 is provided in the upper edge member 15 of the entrance door 1, and the terminal 16 and the circuit board 10 are electrically connected to each other through a thin-film sheet-shaped conductive wire 17. The conductive wire 17 is attached to the outer surface of the entrance door 1 so as to be inconspicuous. Then, the terminal 19 is fixedly installed on the upper part of the door pocket 18 of the entrance door 1, and the terminal 19 and the terminal 16 are connected by a flexible sheet-shaped power cord 20.
A low voltage power supply of about 24 V required for causing the circuit board 10 and the light emitting diodes 11 and 12 of the large number of display bodies 9 to emit light is supplied to the battery 9 via the power cord 20 and the conductive wire 17. The power cord 20 has a sufficient margin as shown in the drawing, and is bent in a U shape so as not to hinder the opening and closing of the entrance door 1.

In the display device 6 of the present embodiment configured as described above, power is supplied to the circuit board 10 and the light emitting diodes 11 and 12 of the respective display bodies 9, and the light emitting diodes 11 of the respective display bodies 9 are supplied. , 12 blink according to a command from the control circuit incorporated in the circuit board 10. In this embodiment, a large number of display bodies 9 brightly illuminate a three-digit number as shown in FIG. 2, and the situation is well visible to pedestrians outside the store. The numbers such as “7, 7, 7” meaning “big hit” are randomly and eccentrically changed and displayed, which can attract the attention of pedestrians.

Since a large number of display bodies 9 are arranged in a fine mesh shape so that the front can be seen through, even if the display device 6 is disposed on the entrance door 1, the display device 6 can be seen through the display device 6. The inside can be seen from the inside of the entrance door 1. Therefore, for example, when waiting with a person or waiting for a time such as a bus, the outside can be visually recognized even when inside the store, which is very convenient. Further, even if the display device 7 is provided on the entrance door 1, light is incident from the outside, so that the vicinity of the entrance door 1 is not darkened, and the customer does not feel discomfort or pressure.

The epoxy resin 14 that molds the surface of each display body 9 has a lens effect of diffusing the light at the time of light emission, so that a clear display can be obtained even if there are the mesh-like gaps 21. You can Further, the large number of display bodies 9 not only display numbers as in this embodiment,
Of course, various patterns such as flowers can be displayed as shown in FIG. When displaying such various symbols, it is most effective if they are arranged at an entrance door of a restaurant or a department store, for example. Further, it can be arranged on a glass facing a sidewalk such as a show window. In this case, the displayed product can be seen from the mesh-like gaps 21 of the display device 6, and a novel display effect which has never existed can be obtained.

[0014]

As is clear from the above description, in the display device of the present invention, a large number of display bodies each including a light emitting diode are arranged in a fine mesh on a transparent thin film sheet so that the front can be seen through. Since it is designed to be able to display arbitrary characters, patterns, etc., it can be easily installed in a game hall such as a pachinko hall, an entrance door of a store, a restaurant, a department store, or a show window, and a high display effect can be obtained. In addition, since it is possible to obtain a front view through the display device, it is possible to obtain a novel display effect that is unprecedented.
