Definitions
- the invention relates to flat displays with a mask in front for spatial stereoscopic and / or holographic display of information
- the images for the right and left eyes are channeled to the viewer through optical masks on a flat display in such a way that the viewer ideally sees only the left image in question with the left eye and only the right image with the right eye.
- Such an arrangement is described in DE 39 21 061 AI (playback device for three-dimensional perception of images).
- This can also be achieved by a complex optical mask with a linear or other suitably structured lighting grid, which, as seen by the viewer, is located behind the display.
- several views of a scene or an object can be observed from corresponding angles (US Pat. No. 5,040,878).
- Flat displays generally have an anti-reflective layer on their surface to reduce reflection.
- This is usually no longer realized in the form of so-called ⁇ / 2 layers, but rather by means of a roughness profile.
- This surface roughness of the flat displays has a negative effect in the known arrangements for spatial stereoscopic display in that, in addition to the desired channeling of the light emerging from the displays, stray light is additionally produced on the eyes of the viewer or viewers, as a result of which the quality of the stereoscopic spatial display is considerably impaired becomes.
- the surface roughness influences the coherence of the light, which leads to a significant reduction in quality.
- the object of the invention is to improve the quality of the spatial stereoscopic or holographic representation in known flat displays having a roughness of the surface.
- the flat displays according to the invention are characterized in particular in that the quality of the spatial stereoscopic or holographic representations in known flat displays having a rough surface is substantially improved by smoothing the surface.
- the surface of the flat display which is anti-reflective due to its roughness, is provided with an evergelling and / or transparent layer, or there is a transparent or evergreen material between the surface and the mask.
- the material is in an airtight body or the space between the flat display and the mask is closed and contains the transparent or evergreen material.
- Another important advantage is that the evergreen and / or transparent layer is simultaneously on the surface of the flat display protects mechanical and / or heat and / or weather influences. This can also be used for anti-reflective treatment.
- the flat screens according to the invention are thus advantageously suitable for a low-interference, spatial, stereoscopic and / or holographic display using flat displays, the surface of which has a roughness.
- the most diverse applications result in areas such as modeling, virtual reality (VR), computer-aided design (CAD), multimedia and games.
- the viewer of the stereoscopic or holographic representation can also change his position without the image reproduction quality deteriorating for this viewer.
- the mask is advantageously tracked according to the new position of the viewer. This is done by determining the position of the viewer, with the mask being tracked accordingly via a drive coupled to it.
- an anti-reflective coating of the flat displays according to the invention is advantageously carried out.
- FIG. 1 is a basic illustration of a flat display with the creation of scattered light due to the roughness of the surface of the flat display
- FIG. 2 shows a basic illustration of a flat display with a possibility of suppressing the scattered light by means of an always-moving material
- FIG. 3 shows a basic illustration of a flat display with an additional transparent layer
- FIG. 4 shows a basic illustration of a flat display with an additional anti-reflective coating by means of a ⁇ / 2 layer
- FIG. 5 shows a basic illustration of a flat display with a material for immersion between the surface of the flat display and a mask for stereoscopic display
- the letters P denote the pixel columns in the flat displays and these are either self-illuminating or provided with backlighting.
- a flat display with a mask for spatial stereoscopic and / or holographic display of information basically consists of a known flat display, the surface of which is provided with an evergating layer (illustration in FIG. 2).
- 1 shows a known arrangement for spatial stereoscopic representation.
- the flat display 1 with the pixel columns P is preceded by a mask 2 towards the viewer, which ideally causes two views to be channeled onto the eyes of the viewer.
- Scattered light 3 arises on the surface of the flat display la and falls as parasitic light into the other eye of the viewer (s). Instead of the intended stereo impression, the viewer also receives the inverted image as a disturbance.
- FIG. 2 shows a flat display 1 with an always embossing layer 4 on its surface, which flattens the roughness of the surface.
- the inverted stereo display is suppressed with the scattered light.
- a transparent layer 5 can also be applied, which serves to protect the surface (illustration in FIG. 3).
- the flat display 1 can be provided with a further additional transparent layer 6 as an anti-reflective layer 6 as shown in FIG. 3.
- the additional anti-reflective coating suppresses reflections that would result from the smoothed surface.
- this layer can also serve to protect the surface.
- a flat display 1 with a mask 2 for spatial stereoscopic and / or holographic display of information basically consists of a known flat display 1 with a mask 2 between the flat display 1 and mask 2 for the stereoscopic display permanent layer 4, which optically suppresses the surface roughness (illustration in FIG. 5).
- the permanent layer advantageously consists of elastic or liquid material, such as immersion oil, in order to simultaneously maintain the mobility of the mask in the case of tracked stereo displays and other arrangements.
- an evergelling material can be located 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 be in a sealed body made of a flexible and transparent plastic or glass.
- the basic structure of a flat display 1 with a mask 2 for spatial stereoscopic and / or holographic representation of information in a third exemplary embodiment essentially corresponds to that of the first or second exemplary embodiment.
- the mask 2 is arranged so as to be displaceable due to the evergating layer 4 and a flexible seal 8 (illustration in FIG. 7).
- the mask 2 can be tracked in accordance with the viewing position, as is required in the case of tracked autostereoscopic arrangements.
