The first semi-transparent mirror (6) is angled in the direction of a viewer (8) and the second semi-transparent mirror (7) is angled away from the viewer (8). The surface (3) of the at least one screen (2, 2', 2") is divided into a first screen region (2'-1, 2"-1) and a second screen region (2'-2, 2"-2). A reflecting surface (9) is arranged at an angle with respect to the surface (3) of the screen (2, 2', 2") at an edge (4) formed on a side of the screen (2, 2', 2") facing away from the viewer (8). The invention furthermore relates to the use of the display device in a vehicle.

In a technology for displaying two-dimensional images on a plurality of display planes placed at different depth positions as seen from an observer to display a three-dimensional stereoscopic image, when a display object having brightness darker than that of a background is displayed, the disclosed method including: generating first two-dimensional images that are obtained by projecting the background plane onto the plurality of display planes along a line of sight of the observer, and displaying the first two-dimensional images on the display planes respectively wherein brightness of each of the first two-dimensional images is changed independently for each display plane; and generating second two-dimensional images that are obtained by projecting the display object onto the plurality of display planes along the line of sight of the observer, and displaying the second two-dimensional images on the display planes respectively in which brightness of each of the two-dimensional images is set to be the same among the display planes. In addition, when using transmissive display plane, when a display object having brightness brighter than that of a background is displayed, transparency of the first two-dimensional images are changed independently for each display plane, and transparency of each of the two-dimensional images is set to be the same among the display planes.

A three-dimensional (3D) image display device is provided. The 3D image display device comprises a first display panel, a second display panel spaced apart from the first display panel at a front side of the first display panel to display a three-dimensional (3D) image, and a spacing panel. A back surface of the spacing panel is coupled to the first display panel and a front surface thereof is coupled to the second display panel. As a result, a specific state in which a predetermined spacing between the first display panel and the second display panel is uniformly maintained through the spacing panel.

A multi-layer projection display including first and second panels separated by a predetermined distance, wherein at least a portion of the first panel overlaps at least a portion of the second panel, and the first panel is disposed between a viewing location and the second panel. The display also includes a controller configured to cause the first and second panels to alternate between substantially opaque and substantially transparent states at a determined frequency, such that the first panel is substantially opaque when the second panel is substantially transparent, and the second panel is substantially opaque when the first panel is substantially transparent. The display further includes a projector configured to project an image onto the first panel when the first panel is substantially opaque, and further configured to project the image onto the second panel when the second panel is substantially opaque.

A three-dimensional display device includes a plurality of transmissive display units arranged in different depth positions in view from an observer and a moiré vanishing element for diffusing light. The moiré vanishing element has a spatial frequency characteristic to cut off a spatial frequency more than a spatial frequency having a cycle being twice as large as an interval of boundaries of pixels forming a first transmissive display unit arranged behind the moiré vanishing element in the view from the observer.

A three-dimensional image display method and apparatus wherein a three-dimensional image of an object is reproduced by three-dimensional display means (5101; ..) by displaying two-dimensional images at different depths and by varying the luminance of the images or portions thereof. The three-dimensional image is distributed to a plurality of observers (5102, 5103, 5104; ..) using a viewing zone distributing means (5105-5107 ;..) which distributes the viewing zone of the three-dimensional display means into a plurality of directions. The distributing means may comprise a plurality of partially reflecting mirrors (5105, 5106, 5107) or a combination of partially reflecting mirrors and optical components. A totally reflecting mirror may be substituted for the final partially reflecting mirror (5107). Alternatively the distributing means may comprise: a plurality of dichroic mirrors or dichroic prisms, or a combination thereof; a holographic optical element with a plurality of reflection angles or diffraction angles, a holographic optical element with a single reflection angle or diffraction angle, or a combination thereof; a prism array having an array of prisms with different refraction directions; a mirror array having mirrors with different reflection directions; or a refraction grating array having different gratings with different refraction angles.

The present invention relates to a frame device or display device and a method for creating a floating display or enhancing 3D experience at borders of a display, wherein a 3D lenticular sheet or other light directing structure is added on the frame of the display such that the frame of the display appears to be at a different position in front of or behind the display. Thereby, the artifact that depth impression on a 3D display disappears when the 3D content touches the frame of the display can be reduced or the impression of a thin floating display can be achieved.

An optical path length adjuster (53) enables electro-optical control of a physical path length between two optical elements, suitable for use in the adjustment of an optical path length within three dimensional display devices that generate a virtual image within a defined imaging volume. The adjuster varies an optical path length between an input optical path and an output optical path and includes: a plurality of first optical (61) elements and second optical elements arranged in alternating sequence along an optical path, each first optical element (62) for determining a polarisation state of a light beam passing through that element and each second optical element for selectively transmitting or reflecting a light beam incident on that element depending on the selected polarisation state of the incident light beam, wherein the optical path length traversed by an input beam on the optical path can be varied by is selecting a particular second optical element at which reflection of the input beam is to occur, the reflected input beam emerging along the output optical path.

Systems and methods for creating and viewing three dimensional virtual slides are provided. One or more microscope slides are positioned in an image acquisition device that scans the specimens on the slides and makes two dimensional images at a medium or high resolution. This two dimensional images are provided to an image viewing workstation where they are viewed by an operator who pans and zooms the two dimensional image and selects an area of interest for scanning at multiple depth levels (Z-planes). The image acquisition device receives a set of parameters for the multiple depth level scan, including a location and a depth. The image acquisition device then scans the specimen at the location in a series of Z-plane images, where each Z-plane image corresponds to a depth level portion of the specimen within the depth parameter.
