Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an illuminated display device using optical fibers as a video transmission body. This is related to a display called "AM" that can synthesize and display images with good image quality.

Regarding advertising display devices that transmit images using optical fibers, various types of devices have been proposed, and some of them are being put into practical use. In particular, display devices for large signboards using optical fibers have been recognized for their superiority over conventional neon signs in terms of power consumption, maintenance, diversification of display patterns, etc., and their commercialization is urgently needed. There is. However, the advertising display devices that have been put into practical use to date vary in design, shape, size, installation location, etc., and it is common for them to be manufactured to custom specifications to meet the needs of each case. . This requires considerable production costs and time, which is a bottleneck in expanding the market.

As the illuminated display device becomes larger as described above, the amount of optical fibers used will inevitably increase, and the storage and installation of the optical fiber bundle in the direction of the back of the display panel will become extensive, making the entire device larger than necessary. Become. For this reason, it has already been proposed to divide the display into multiple pieces, but in this case the display would be different depending on each divided display, or it would be no more than a unit of optical fibers. However, in the former case, there was a problem that it was not possible to integrate each unit to produce a single display as a whole.Also, in the latter case, the optical fiber was divided into multiple pieces, so although unitization was possible, each divided unit In order to finally converge the proximal end, the device becomes large-scale, and there is a drawback that it is not possible to utilize the advantages of unitization to its fullest extent.

Therefore, the present applicant previously proposed a device in which a light source device with a driving filter is provided for each display unit, and the individual driving filters are synchronized and driven to perform display (Special Application Sho!).
;A-/U33/K).

According to this device, the individual display units can be made relatively compact, and a single display can be made by summing up the display units, but there is a problem in that when two images are displayed, the boundaries between each unit are noticeable.

The present invention has been made in view of these circumstances, and its gist is that the display body is composed of a plurality of display units, and the display unit is composed of a large number of optical fibers and a display board. This is an illuminated display device in which the base ends of the optical fibers in each display unit are focused and placed opposite to the respective light sources, and the tips of the optical fibers in each display unit are spread out and arranged on the display board. In addition, there is provided an illumination type display device characterized in that adjacent display units are solidified with their tips -m overlapping each other at a boundary portion.

The present invention will be described below with reference to drawings of embodiments.

(However) in the figure is a display unit constituting the display body of the present invention,
As shown in the figure, this display unit (g)) is composed of a large number of optical fibers and a display plate (c), and the base ends (7, 2) of the optical fibers (1) are converged. They are each supported so as to be opposed to the light emitted by the projector (3) as a light source. On the other hand, the tip of the optical fiber (1) (/
, 2) are expanded and arranged on the display board (, 2), but at this time, the tips of each other (/
A part of 2) is overlapped and solidified. In other words, FIGS. 2 and 3 model the arrangement and fixation of the tips of this optical fiber (1). If the tips of the two are represented by circles, they overlap each other at the boundary (A) as shown in the figure. In Fig. 1, the boundary part (including the overlapping 5 lines) is set over several rows, but in the border part CB) in Fig. 3, there is an overlap of one row each. This overlapping tip is filled in black. In addition, the optical fiber used in the present invention (1
), glass-based or plastic yarn optical fibers can be used, but plastic yarn optical fibers are suitable from the viewpoint of ease of manufacturing and flexibility. Also, the thickness and pitch of the optical fiber (1) are constant for the display unit)
Optical fibers (1) with a diameter of 0.5 to 300 mm are usually arranged at a pitch of 30 nm, although this varies depending on the size and usage conditions.

Further, (3) in the figure is a projector as a light source, and serves as an image source for the above-mentioned display unit.

The film loaded into this projector (3) is
It is produced in advance so that there will be some overlap when photographing. Therefore, care must be taken so that the amount of overlap at this time matches the overlap of the boundaries φ) and 2) between the display units (U).

When the projector (3) of the illuminated display device of the present invention configured in this manner is turned on and the respective films are driven synchronously, the image on the film is enlarged and projected onto the display board (K). An image that is a combination of the two images will be displayed.

In this case, the boundary g(A) of mutual display units) (U),
In (B), the tips (/, 2) partially overlap with each other, and the film images also overlap, and there are only a few other overlapping films, so the image quality is such that you don't notice the boundaries. The excellent display will be illuminated.

The examples shown in FIGS. 1 to 3 above show the most basic combination of display units (b) of the present invention, but the number of display units (b) constituting the display body can be further increased. For example, Fig. 3 is a combination of three \display units) (U), and the tip (12) of the optical fiber (1) is rounded with corners, triangles, and circles.In this case, the boundary part is (C) and Q)), the tips (/2) of each other are oat-wrapped, and especially the tip (/2) of the optical fiber (1) in the triangular intermediate display unit. The number of a) is the number i that overlaps from the display units on both sides.
The sum of (/Y) is 〈equal. Therefore, the film of the projector (3) corresponding to such a display is adjusted so as to correspond to this overlap. Of course, it is also possible to roughly increase the number of combinations of display units (U), and may include not only serial combinations but also parallel combinations.

In the illustrated example, a projector (3) is used as a light source, but it is also possible to replace this with a projection device of another image source. Because of this, the boundaries between adjacent display units are not noticeable.
It is advantageous to provide an illuminated display device that displays superior image quality.
