Abstract

Images on a plurality of displays 10 are combined without gaps in a single output display 12 using bundles of optical fibres 14. The fibres may be bonded together in a matrix or to the output display and may be bonded to the input displays, which are electromagnetic radiation emitting displays such as LCDs or CRTs. The fibres may be tapered in thickness and the output display may be shaped to any desired profile. Errors in fibre alignment/location may be corrected by appropriate software.

Description

IMPROVEMENTS IN OR RELATING TO IMAGE DISPLAY APPARATUS The present invention relates to an image display apparatus e.g. an apparatus to display a single image from a combination of multiple images.
In particular the invention relates to apparatus to provide a large screen display of television images.
It is known to provide relatively large sized television screens but the images displayed on such screens are of a relatively poor brightness, contrast and definition when compared to smaller television screens.
Another form of display of television images on a large screen is to provide a number of separate screens which are separated by a grid. Whilst such screens provide adequate individual images, the bars of the grid separate the images and cause distraction and annoyance.
The present invention seeks to provide an image display apparatus in which the segmentation between the separate images if virtually imperceptible.
Accordingly the present invention provides an image display apparatus comprising a plurality of input displays and a single output display, the images from the input displays being transmitted to the output display by means of fibre optic cables.
The present invention will now be more particularly described with reference to the accompanying drawing which shows diagrammatically one form of image display apparatus according to the present invention.
Referring to the figure there is shown four image input displays (10) which can be any form of electromagnetic radiation emitting display, e.g. liquid crystal display, cathode ray tube and other similar forms of display.
The input displays (10) are connected to an output display screen (12) by means of fibre optic bundles (14).
The bundles of fibre optic cables are bonded to the surfaces of the input displays at (16), combined in the same sequence and bonded to the output display screen (12) at (18).
One end of the fibres are physically aligned with the pixels in each input display and the other end of the fibres are combined in the same sequence and bonded together via matrix to form the output display, or attached, as described above, to a screen.
The screen can be of any suitable, transparent and durable material.
The bonded output fibres can be either machined into or bonded onto the pre-formed output display surface.
The images on the input displays can be adjusted by the use of appropriate software so that an image produced on the output display is continuous in that no junctions can be seen between the outputs of the individual displays. Also, errors in fibre alignment/location can be corrected by appropriate software.
It will be appreciated that an apparatus according to the present invention allows any number of input displays to be combined into a virtually seamless output display surface. The output display surface can be shaped to any form.
The output display resolution can be increased by tapering the fibres from the input displays (thick end) to the output display (thin end). The output display size can be increased and the resolution of the image can be decreased by tapering the fibres from the input displays (thin end) to the output display (thick end).
The apparatus also allows many relatively inexpensive input displays to be combined into a single large output display surface.
The apparatus also allows multiple relatively expensive large input displays to be combined into a much larger display surface. The cross-section of the fibres can be shaped in order to increase alignment efficiency and display resolution.

Claims (9)

  1. CLAIMS 1. An image display apparatus comprising a plurality of input displays and a single output display, the images from the input displays being transmitted to the output display by means of fibre optic cables, the output display being formed by the fibre optic cables being bonded together in a matrix.
  2. 2. A display apparatus as claimed in claim 1 in which the fibre optic cables are tapered in thickness.
  3. 3. A display apparatus as claimed in claim 1 or claim 2 in which the output display surface is shaped to any desired profile.
  4. 4. A display apparatus as claimed in any one of the preceding claims including a display surface co-operating with the output display.
  5. 5. A display apparatus according to any one of the preceding claims in which the input displays comprise electromagnetic radiation emitting displays.
  6. 6. A display apparatus as claimed in any one of the preceding claims in which the input displays comprise cathode ray tubes.
  7. 7. A display apparatus as claimed in any one of the preceding claims in which the fibre optic cables are bonded to the input displays.
  8. 8. A display apparatus including data processing means to adjust the images transmitted from the input displays so as to either correct any misalignment of the fibre optic cables and/or to reduce or eliminate overlap of the input images on the output display.
  9. 9. A display apparatus constructed and arranged for use and operation substantially as herein described and with reference to the accompanying drawings.
