Display panel constructions eliminating discontinuities between adjacent panels

Claim 2

A display of comparatively large size comprising a plurality of self-contained individual electrically addressable display panels each having a display zone for displaying visual information and arranged in a formation so as to collectively provide a composite display of increased area, the display zone of each of said individual panels being surrounded by a border portion of said panel which is incapable of displaying visual information, extends outwardly of said display zone, and has significant dimensions relative to the dimensions of said display zone of said panel, said display further comprising a fibre optic image transform construction arranged in front of the display panels for transforming an image collectively provided by the panels into a corresponding and continuous image in which the border discontinuity between adjacent panel display zones is substantially eliminated.

Claim 3

A display according to claim 1 wherein the fibre optic construction comprises a fibre optic plate and fibre optic guiding elements arranged to guide an image from panels arranged at an angle to the fibre optic plate.

Claim 4

A display according to claim 1 wherein the fibre optic construction includes fibre optic expander plates for expanding the display zones, each expander plate having optic fibres therein which extend in directions transverse to said panels, said fibres being arranged closer together at their ends nearest the panels than at their ends more remote from the panels.

Claim 5

A display according to claim 3 wherein at least part of the fibre optic construction comprises glass fibres.

Claim 6

A display according to claim 3 wherein at least part of the fibre optic construction comprises fibres of a plastic material.

Claim 7

A display according to claim 1 wherein the panels are electroluminescent display panels.

Claim 8

A display according to claim 1 wherein the panels are liquid crystal display panels.

Claim 9

A display of comparatively large size comprising a plurality of self-contained individual electrically addressable display panels arranged in a formation adapted to collectively provide a composite display of increased area, each of said display panels including a bordered periphery which is incapable of displaying visual information, and within that bordered periphery an addressable display zone capable of displaying visual information, the bordered periphery of each panel comprising a dead zone which extends outwardly of the display zone of said panel and has significant dimensions relative to the dimensions of said display zone of said panel, each of said display panels comprising an electrically responsive medium in the form of a layer filling the display zone of said panel, first and second sets of electrode structures respectively on opposite sides of the layer, cooperative with each other, and defining a multiplicity of electrically addressable display elements within the display zone of said panel, and connector means, disposed about the bordered periphery of said panel, cooperative with the first and second sets of the electrode structures for applying electrical address control to selected elements for defining visual information to be displayed by the display zone of said panel; and fibre optic image transform construction means arranged in front of said plurality of display panels, said transform construction means being in optical contact with the display zone of each of said panels and including a fibre optic plate defining a front display surface, arranged so that when the panels are addressed, discontinuities due to said bordered peripheries are substantially eliminated and a collective and continuous image is observed at said front display surface of said fibre optic plate.

Claim 10

A display of comparatively large size comprising a plurality of self-contained individual electrically addressable display panels arranged in a formation adapted to collectively provide a composite display of increased area, each of said display panels including a bordered periphery which is incapable of displaying visual information, and within that bordered periphery an addressable display zone capable of displaying visual information, the bordered periphery of each panel comprising a dead zone which extends outwardly of the display zone of said panel and has significant dimensions relative to the dimensions of said display zone of said panel, each of said display panels comprising an electrically responsive medium in the form of a layer filling the display zone of said panel, first and second sets of electrode structures respectively on opposite sides of the layer, cooperative with each other, and defining a multiplicity of electrically addressable display elements within the display zone of said panel, and connector means, disposed about the bordered periphery of said panel, cooperative with the first and second sets of the electrode structures for applying electrical address control to selected elements for defining visual information to be displayed by the display zone of said panel; and fibre optic image transform construction means arranged in front of said plurality of display panels, said transform construction means being in optical contact with the display zone of each of said panels and including a fibre optic plate defining a front display surface, arranged so that when the panels are addressed, discontinuities due to said bordered peripheries are substantially eliminated and a collective and continuous image is observed at said front display surface of said fibre optic plate.
