Flat display comprising a frontal mask for the spatial, stereoscopic and/or holographic representation of information

Abstract

An arrangement for spatial stereoscopic and/or holographic representation of information has a flat display having a rough surface and a frontal mask connected to the flat display. The rough surface has an immersing layer or a transparent layer or both provided thereon. As an alternative, between the rough surface of the flat display and the mask a space is provided and a closed body made of transparent material and containing immersing material is positioned in the space between the rough surface of the flat display and the mask.

Description

BACKGROUND OF THE INVENTION

[0001] The invention relates to flat displays with a frontal mask for spatial stereoscopic and/or holographic representation of information.

SUMMARY OF THE INVENTION

[0002] It is an object of the invention to improve the quality of spatial stereoscopic or holographic representation on known flat displays that have a rough surface.

[0003] This object is solved in that a rough surface of the flat display is provided with an immersing layer and/or with a transparent layer or in that between the surface of the flat display and the mask is transparent and/or immersing material is located.

[0004] The embodiment, wherein the space between the surface of the flat display and the mask contains immersing material, results in a simple possibility for expanding on already present flat displays by means of the mask.

[0005] A sealed space between the surface of the flat display and the mask containing an immersing or transparent material results in a compact flat display for spatial stereoscopic and/or holographic representation.

[0006] With the embodiment, wherein the mask is arranged slidably relative to the flat display, the viewer of the stereoscopic or holographic representation is able to change his position without this decreasing the image quality for this viewer. Advantageously, the mask is being tracked in accordance with the new position of the viewer. This is realized by a position determination of the viewer wherein the mask is being tracked by means of a drive coupled thereto.

[0007] With at least one λ/2 layer, anti-reflective properties are advantageously provided to the flat display according to the invention.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0017] In one variant of the second embodiment (FIG. 6), an immersing material can be contained in a closed space similar to a layer 4 between the flat display 1 and the mask 2. This material can be enclosed by a seal or can be arranged in a closed member of a flexible or transparent plastic material or glass.
