Art exhibition device and a video picture exhibition method which are capable of providing renditions by a spatial image and a projected image, in combination are provided. The exhibition device includes a display portion configured to image-form a spatial image; and a projector configured to project a video picture onto an object. The video picture exhibit ion method using the exhibition device provides a video picture related to the spatial image projected from the projector disposed in a position hang over the display portion toward an upper surface of the display portion. The display portion is configured to image-form a video picture displayed on a display surface of a display disposed in an attitude inclined under a micromirror array through the micromirror array disposed in light-transmissive fashion as a spatial two-dimensional video picture standing up obliquely in a spatial position lying over the micromirror array.

A display device has a display, operable to generate a real image, and an optical system, comprising one or more lenslets, arranged to generate a virtual sub-image from a partial real image on the display, by each lenslet projecting light from the display to an eye position. The sub-images combine to form a virtual image viewable from the eye position. At least one lenslet is symmetric with respect to a plane, and the display surface is cylindrical with its axis perpendicular to that plane.

An optical device includes a light guide plate configured to guide light within a plane parallel to an emission surface, and a plurality of light focusing portions to which the light guide plate guides directional light. Each of the plurality of light focusing portions is provided with an optical surface configured to create from the directional light incident thereon emission light in a direction substantially converging on a single convergence point or convergence line in a space or to create emission light that substantially diverges from a single convergence point of convergence line in a space and exits from the emission surface. The plurality of light focusing portions are provided near the emission surface of the light guide plate, and each of the plurality of light focusing portions is formed along a predetermined line within a plane parallel to the emission surface.

In one preferred form illustrated in FIG. 1 there is provided an autostereoscopic display 10. The display 10 includes a layer 20 of pixel sources 22. The display includes a source screen 12 and a lens structure 14. The source screen 12 is able to separate light from each pixel source 22, in the layer 20 of pixel sources 22, into view position input sources 32 each corresponding with a different view position 40. The lens structure 14 has a view position configuration 36 and a views configuration 38. The view position configuration 36 and the views configuration 38 of the lens structure 14 are able to transmit light, that is received from the view position input sources 32 as corresponding lens structure inputs 34, as views 39 grouped in viewing positions 40.

An autostereoscopic display comprises a pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors and a view forming arrangement comprising an array of lens elements. The pixels form a square (or near square) grid, and the lenses also repeat in a square (or near square) grid. A vector p is defined which relates to a mapping between the pixel grid and the lens grid. Regions in the two dimension space for this vector p are identified which give good or poor banding performance, and the better banding performance regions are selected.

A smartphone stereoscope including a receptacle for holding a smartphone in a wide-image format position. The receptacle includes magnifying lenses and a partition running parallel to the long sides of the smartphone and aligned with a dividing line between two stereoscopic images arranged side-by-side on the smartphone screen. The partition swivels or pivots on a base between use and folded positions. A lens holder including lens holders for accommodating magnifying lenses is provided on the base along with a support bar. The bar contacts a longitudinal edge of the smartphone and is provided at an upper end of the partition and, in the use position runs transversely to the partition. A clamping means holds a smartphone when the longitudinal edge is put against the support bar. In the folded position the partition, base, support bar and lens holder lie parallel to each other in a plane, or in adjacent planes.

A portable virtual reality device, which is provided with a board having a length to correspond the focal distances of the left and right lens; a supporting board that it deployed and foldable based on the board; left and right lens plates that are deployed and folded left and rightward on a rear surface of the board based on the board. The smart phone is mounted simply to correspond to the focal distances of the left and right lens when it is used, and when it is carried, the left and right lens plates and the supporting board are fold to form a thin film to be carried conveniently.

Three-dimensional (3D) electronic displays provide different 3D views and employ one or both of an array of multibeam diffraction gratings arranged in offset rows and light valves having color filters. The displays include a plate light guide configured to guide light beams at a non-zero propagation angle, a multibeam diffraction grating configured to couple out a portion of the guided light beams as a plurality of light beams having different principal angular directions representing the different 3D views, and light valves configured to modulate the differently directed, coupled-out light beams. The multibeam diffraction grating may be a member of the array arranged in offset rows and the display may further include light valves having color filters. Alternately, the light valves include color filters and the display may further include the array of multibeam diffraction gratings arranged in offset rows.

A 3D display device and the driving method for the 3D display device are provided. The 3D display device includes a liquid crystal display panel for monochrome display, and an electroluminescence display panel for color display disposed under the liquid crystal display panel; the electroluminescence display panel includes a plurality of regions arranged in a matrix, the plurality of regions form columns of bright regions and columns of dark regions, which are arranged alternately the liquid crystal display panel includes a plurality of first sub-pixels arranged in a matrix; each bright region of the electroluminescence display panel corresponds to at least two first sub-pixels adjacent in row direction of the liquid crystal display panel.

The present disclosure relates to a display apparatus and a three-dimensional display method thereof. A via hole at least passing through a base substrate is formed in an array substrate of a liquid crystal display panel, and a signal line on a upper surface of the array substrate can be connected with a driving chip bonded onto an electroluminescent display substrate, through to the via hole on a lower surface of the array substrate and through a conductive material in an optical clear adhesive. A signal line on the electroluminescent display substrate also can be connected with a driving chip bonded onto an upper surface of the array substrate, through the conductive material in the optical clear adhesive on a lower surface of the array substrate and through the via hole.
