Flat-panel display
First Claim
1. A display of the flat-panel type, comprising a source (1) of one or more rays, means for modulating the intensity of the rays, a panel (2) which is not opaque to the rays and enables the emission of light at some position along each ray when the ray is directed into a side of the panel, and means (3) for selecting such positions;
- wherein the display includes a projector (1), containing the means for modulating the intensity of the rays, for modulating the input rays line by line for input into the panel, and the selecting means correspondingly selects one line at a time on the panel so as to display that line from the projector.

Abstract
A video display for two or three dimensions has a flat liquid-crystal screen 2 which ejects light from the plane at a selectable line 3. One or, in the case of a 3-D display, several video projectors 1 project a linear image into the plane from an edge. A complete image is written on the screen by addressing the line with appropriate images as it is scanned down the screen. To screen a three-dimensional image the video projectors, each projecting an image as seen at a slightly different angle, combine to constitute a three-dimensional display which produces a three-dimensional image that is one line high.

- 8. A display of the flat-panel type, comprising a source (1) of one or more rays, means for modulating the intensity of the rays, a panel (2) which is not opaque to the rays and enables the emission of light at some position along each ray when the ray is directed into a side of the panel, and means (3) for selecting such positions, wherein the display is adapted to produce a three-dimensional image and to this end comprises a ray-projecting device (1), for directing the modulated rays into the panel at various azimuthal angles, the rays being emitted from the panel as they are selected by the selecting means (3) at respective azimuthal angles corresponding to their angle of entry into the panel.

11. A display of the flat-panel type, comprising a source (1) of one or more rays, means for modulating the intensity of the rays, a panel (2) which is not opaque to the rays and enables the emission of light at some position along each ray when the ray is directed into a side of the panel, and means (3) for selecting such positions, wherein the panel includes a reflective sheet and a transducer (43) for producing a localised linear acoustic or surface wave in the sheet (2), the presence of the wave at a given position causing reflection of the ray and thus the said selection of that position.

12. A method of displaying an image, in which light making up successive lines of the image is directed into the side of a panel containing a flat layer (2) of modulatable material, and the material is addressed a line at a time to modulate it and thus to cause emission over the plane of the layer so as to build up the image.
