Abstract
Abstract Display panel for image presentation and/or recording, comprising a matrix formed of a horizontal (1A-D) and a vertical (33A-E) element set respectively, adapted to be addressed for selecting points that shall present, alternatively pick up light, one of these element sets acting as shutter means (33A-E) for light. The other element set consists of optical light conductors (1A-D) adapted to receive (39A-D), alternatively to emit (40A-D) light at their ends located outside the matrix itself. The light conductors, which can be in the form of optical fibres, are provided with means (2A-D) positioned at said points for diverting light out of, alternatively into the light conductors (1A-D) transverse to their longitudinal direction. This transverse light directly forms the image presented, alternatively directly represents the image recorded, by addressing of both element sets (1A-D, 33A-E). This form of display panel has various practical applications, for example in television sets, data terminals, in particular two-way television and two-way data terminals, which can both present an image and perform recording of a picture or scene.
