Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an internally lit electronic display device used as a signboard or a guide plate.

[0002]

[Prior art]

 Conventionally, as an electronic display device of this type, a display panel is formed by providing a background portion having a light transmittance lower than that of the display portion around a display portion having a light-transmitting property, which represents characters and the like. A fluorescent lamp is provided behind this display panel.

This display device attempts to identify the display content by causing a difference in brightness between the display portion and the background portion of the display panel as the fluorescent lamp is turned on.

[0004]

[Problems to be solved by the device]

 However, in such a display device, since the support for the fluorescent lamp and the lighting circuit are bulky, the depth of the device becomes large, and the display is not visible when it is hung on a wall or placed on the floor or a table. There was a problem of being bad.

Further, unless the background portion is darkened as much as possible, the distinctiveness of the display portion is deteriorated, so that it is difficult to provide the background portion with gaze.

Therefore, an object of the present invention is to provide an electronic display device which is excellent in appearance at the time of installation and has a gaze property in the background portion.

[0007]

[Means for Solving the Problems]

 In order to solve such a problem, in the present invention, a transparent plate has a back surface on which a reflective material for reflecting light transmitted from the front side of the plate is attached, and a display having a required transparent shape. And a sheet-shaped light-emitting body that emits light when energized is positioned behind the display panel to form a display panel.

In such a display device, since the light-emitting body that illuminates the display panel from the front side is in the form of a sheet, the depth can be reduced, and the light-emitting body can be hung on a wall, placed on the floor or on a table. Is also excellent in appearance.

Further, since the surface of the background portion of the display panel is a mirror surface, a high visibility is given to the background portion by the reflected image, and a beautiful appearance can be obtained in combination with the display portion through which the light of the light emitting body is transmitted. .

[0010]

[Embodiment of the invention]

 1 and 2 show a first embodiment of a display device according to the present invention. In this display device, a sheet-shaped light emitting body 2 is superposed on the back surface side of a display panel 1, and each of the display panel 1 and the light emitting body 2 is sandwiched between a frame 3a of a stand 3 and a contact plate 3b. It is configured.

In the display panel 1, as shown in FIG. 2, a reflective material 5 that reflects the light transmitted from the front surface side of the plate body 4 is attached to the back surface of the transparent plate body 4 made of a glass plate or an acrylic plate. The background portion 6 and the character-shaped display portion 7 having a light-transmitting property are provided.

Normally, silver is used as the reflecting material 5, and when forming the background portion 6, silver is chemically deposited on the plate body 4. The display unit 7 may be formed by depositing silver on the entire back surface of the plate body 4 and then scraping off a part of the silver. It may be formed by depositing silver only on the surface.

A lead wire 10 reaching the plug 9 via the switch box 8 is connected to the light emitting body 2, and when the switch box 8 is turned on and electricity is applied, the front surface of the light emitting body 2 emits light. As the luminous body 2, as shown in FIG. 2, a moisture absorbing nylon film 2a, an aluminum foil 2b, an insulating film 2c containing barium metatitanate, a luminous layer 2d containing zinc sulfide as a phosphor, polyethylene. A film 2e made of terephthalate (PET) and a nylon film 2f for moisture absorption are superposed in this order from the back side, and these are wrapped with a moisture-proof fluorine film 2g, an ultraviolet ray blocking film 2h is provided on the front side, and a cover film 2i is further wrapped. In addition, a transparent electrode layer 2j made of indium tin oxide is preferably provided between the layers.

In this display device, since the light-emitting body 2 that illuminates the display panel 1 from behind is in the form of a sheet, the depth of the frame 3a can be reduced, and the frame 3a can be hung on a wall or placed on the floor or a table. Even if you do it, it will be excellent in appearance.

Further, since the surface of the background portion 6 of the display panel 1 is a mirror surface, a high visibility is given to the background portion 6 by the reflected image, and a beautiful appearance is obtained in combination with the display portion 7 through which the light of the light emitting body 2 is transmitted. Can be obtained. Therefore, it is effective when used as a reception guide at a wedding hall, and can be brought back as a souvenir after the ceremony.

If a blinking circuit is incorporated in the switch box 8 and the display section 7 blinks, a more effective effect can be produced.

FIG. 4 shows a second embodiment of the display device according to the present invention. In this display device, the display panel 1 and the light-emitting body 2 are sandwiched between the frame 11a of the frame 11 and the backing plate 11b. The display unit 7 is formed in a rectangular shape in the center of the display panel 1, and a film 12 showing characters is attached inside the display unit 7.

When the display panel 1 and the light-emitting body 2 are housed in the frame 11 as described above, the display panel 1 and the light-emitting body 2 can be hung on a wall and used, and at this time, the frame 11 does not significantly project from the wall surface, which impairs the aesthetics of the surroundings. There is no.

FIG. 5 shows a third embodiment of the display device according to the present invention. This display device is used by being installed on the floor as a guide light for a wedding reception hall or the like, and legs 14 are provided below the frame 13 that holds the display panel 1. Even with such a configuration, the depth of the frame 13 does not increase, so that the frame 13 is not obstructed even when installed in a corridor or the like, and does not give a feeling of pressure.

[0020]

[Effect of the invention]

 As described above, since the display device according to the present invention can be reduced in depth, it does not take up a lot of space for installation and is excellent in appearance. Further, since the background portion surface of the display panel is a mirror surface, the reflected image gives the background portion a high degree of gaze, and a beautiful appearance can be obtained in combination with the display portion through which the light of the light emitter is transmitted.
