In a volumetric display and a head-mounted display having the volumetric display, the volumetric display includes a plurality of self-luminous display panels and a plurality of shutter panels. The display panels are configured to display an image forwardly, and are spaced apart from each other along a forward and backward direction. Each of the shutter panels is disposed between the self-luminous display panels adjacent to each other. A pixel of the self-luminous display panel corresponds to a pixel of the shutter panel. The shutter panel adjusts transmittance of a light emitted at a plurality of the pixels of the self-luminous display panel which is disposed at a rear side of the shutter panel, for each pixel.

A method and system for generating a 3D volumetric image. The method and system comprise rotating about a rotation axis a light modulating surface comprising separately controllable light modulating regions located across the light modulating surface and controlling separately the modulation of the light modulating regions to generate the 3D volumetric image upon rotation of the light modulating surface about the rotation axis. A characteristic of two or more selected light modulating regions of the light modulating surface is then varied in accordance with respective spacings of the two or more selected light modulating regions from the rotation axis.

The invention relates to a display device (10) comprising a display screen arrangement (12) and a storage volume (14). The display screen arrangement (12) is arranged in such a way that the display screen arrangement can be moved out of and into an interior space (30) of the storage volume (14) through an opening (16) of the storage volume (14) along a predetermined movement direction (18) between a storage position and at least one use position different from the storage position. The display device (10) has a support element (36) which extends from the opening (16) along the predetermined movement direction (18) away from the interior space (30) of the storage volume (14) and is designed to mechanically support the display screen arrangement (12) when it is at least partially pushed out of the storage volume (14).

An aerial-floating three-dimensional volumetric display apparatus, comprising: a three-dimensional display screen (100), which is used for using light-field three-dimensional imaging technology to display three-dimensional content; and a retroreflective imaging panel (200), wherein the three-dimensional display screen (100) is obliquely arranged, reconstructed light rays pass through the retroreflective imaging panel (200) and then reconstruct a three-dimensional light field in mid-air, so as to realize the floating display of three-dimensional content, and the retroreflective imaging panel (200) comprises optical waveguides that are alternately arranged, so as to form a plurality of optical channels for the exit of the reconstructed light rays. The optical waveguides are arranged on the basis of preset dimensions, or the three-dimensional display screen (100) emits the reconstructed light rays on the basis of a preset angle, such that the reconstructed light rays are controlled to be reflected only a specified number of times in each optical waveguide. Thus, the generation of ghost images is fundamentally prevented, and after ghost images are eliminated, floating 3D display technology achieves better visual effects and enhanced clarity.

One embodiment of a display system includes one or more light sources, one or more spatial light modulators, and a plurality of scatterers. One embodiment of a method for displaying content includes computing at least one of a phase or an amplitude modulation associated with two-dimensional (2D) or three-dimensional (3D) content, and causing one or more spatial light modulators to modulate light based on the at least one of a phase or an amplitude modulation to generate modulated light, where the modulated light is scattered by a plurality of scatterers.

A system for visualization includes a camera rig having a plurality of cameras that capture images from one or more perspectives; and at least two visual guides defining a volumetric space within an environment that may be physical, virtual, and / or a hybrid of the two and associated with the camera rig. The volumetric space is updated based on changes to one or more parameters associated with camera rig, manually, automatically, and / or in real-time.
