In the display device described above, when an image is displayed on a display screen having a large display area, a large number of pixels are required. Was bigger. However, increasing the size of the converging section requires increasing the distance between the converging section and the projector that displays the original image. If the interval is widened, the amount of light applied to the focusing unit decreases, so that the image displayed on the display screen becomes dark. Further, if the distance between the distal end of the optical fiber and the distal end of the optical fiber arranged in the display section is simply increased in order to increase the display area, the display screen becomes dark. An object of the present invention is to provide a display device in which an image is not darkened even when a display area of a display screen is increased.

Means for Solving the Problems One end of a plurality of optical fibers is focused, the other end of the optical fibers is arranged in a matrix on a display section, and an original image is irradiated to the focusing section to pass through the optical fibers. In a display device that displays an image on a display unit,
A plurality of projection devices that project the same original image, a plurality of focusing units that focus one end of the optical fiber and are irradiated with the original images projected from each of the plurality of projection devices, and an original image that is projected onto the plurality of focusing units This is a display device in which optical fibers for guiding the light of the pixels at the same position are gathered and arranged in the display unit.

[0005]

FIG. 1 shows an embodiment of a display device according to the present invention. 1A to 1D show the original image displayed on the display screen by the projector, that is, the original image. 1A-1D
All the original images projected from the projector project the same image at the same timing. Currently, the projectors include a liquid crystal projector and a DLP projector, but the present invention can be applied to all projectors. Also, here, a projector is described as an embodiment of an apparatus for displaying an original image. However, for example, a white light bulb is prepared, and an apparatus that displays an image by coloring with a multicolor cellophane or the like, that is, a projector What is necessary is just to use the projection device which is a high-level concept including the above.

[0006] Images projected from the projectors 1A to 1D are radiated to the focusing units 3A to 3D. The image of the projector 1A is emitted to the focusing unit 3A, the image of the projector 1B is emitted to the focusing unit 3B, the image of the projector 1C is emitted to the focusing unit 3C, and the image of the projector 1D is emitted to the focusing unit 3D. That is, the focusing units 3A to 3D are prepared by the number of the projectors 1A to 1D.

The converging sections 3A to 3D are portions where the rear end 4b of the optical fiber 4 is converged, and the front end 4a of the optical fiber 4 is attached to the display section 6. Tip 4 attached to display 6
a are arranged in a matrix.
Are the pixels of the image displayed on the display unit 6.

When the original images projected from the projectors 1A to 1D are applied to the focusing units 3A to 3D, the light is guided through the optical fiber 4 and emitted from the distal end 4a of the optical fiber attached to the display unit 6. Is done. The same image as the original image emitted from the projectors 1A to 1D is displayed on the display screen of the display unit 6 by the light emitted from the distal end portion 4a.

In this figure, the rear end 4b of the optical fiber 4 is attached to the converging sections 3A to 3D for easy viewing of the drawing.
Although only one optical fiber 4 in which the distal end 4a of the optical fiber 4 is attached to the display unit 6 is described, actually, the distal end 4a of all the optical fibers 4 attached to the focusing units 3A to 3D is formed. , Are mounted at predetermined pixel positions of the display unit 6.

FIG. 2 is an explanatory diagram of the display on the display screen of the display device shown in FIG. As described with reference to FIG. 1, the focusing units 3A to 3D form a display screen by focusing the rear ends 4b of the plurality of optical fibers 4, and include the focusing units 3A to 3D.
Each of the rear ends of the optical fibers arranged in 3D is a pixel constituting an original image. The original images projected on the focusing units 3A to 3D correspond to the projectors 1A to 1 shown in FIG.
The same image is irradiated at the same timing from 1D.

The pixel 10a at the upper left end of the focusing units 3A to 3D will be described.
The color of 0a becomes the same color because the same image is sent as described above. On the display screen of the display unit 6, the focusing units 3A to 3A
The pixels 10a at the same place displayed in 3D are arranged so as to be grouped as shown in the figure. That is, in the display unit 6, four pixels at the same position of each of the focusing units 3A to 3D are aggregated to be one pixel. With this arrangement, the display of the original image on the display unit 6 is simply quadrupled. The reason for simply quadrupling is that four projectors are used, and pixels at the same position of the converging unit that projects the respective original images are aggregated. Any number of projectors can be used, and as the number of projectors increases, the number of pixels for one pixel of the display unit increases, so that the display screen of the display unit 6 can be enlarged.

As described above, such a display is made possible by attaching the rear end 4b of the optical fiber 4 to the converging sections 3A to 3D and attaching the distal end 4a of the optical fiber 4 to the display section 6. Become.

Although the description has been given of the case where the display is performed on the display unit by using all the four focusing units 3A to 3D, the four optical fibers 4 are connected as described above, and for example, the focusing unit 3A is used. Is not emitted from the display unit to the display surface of the display unit, that is, even when the projector 1A is not used, only that part is not displayed and the other projectors 1B to 1B are not displayed.
It is possible to display only D. That is, the display is performed by four projectors 1A to 1D in FIG. 1, and the actual number of use is not limited to four, but can be two or three.

[0014]

According to the present invention, the same original image is projected on each focusing section by using a plurality of projectors.
Since pixels at the same position in the original image of each focusing unit are grouped into one pixel in the display unit, a larger display screen can be configured as the number of projectors is increased. In addition, since the original image is projected by a plurality of projectors, the area of the focusing unit can be reduced, so that the distance between the projector and the focusing unit can be reduced, and the light amount does not decrease much. Since the light passes through the optical fiber and is emitted to the display screen of the display unit without decreasing the light amount, the display screen also becomes bright, and a high-quality display can be performed. In addition, since the same number of pixels as the number of projectors to be used is configured to be one pixel on the display screen of the display unit, even if some projectors fail and cannot be used, other pixels can be used. It can be displayed by a projector.
