The top surface (201) and the side surfaces (202, 203) of the support (2) form a cavity. The baffle plate (3) is fixed inside the cavity, and divides the cavity into two independent cavities (4). An accommodation space (5) for a terminal is equipped between a bottom edge of the baffle plate (3) and a bottom of the cavity. The cavity is equipped with an operating opening (6) by which an operation is conducted on the terminal. The top surface (201) is equipped with two mounting holes (7) which are positioned on two sides of the baffle plate (3) respectively, and are connected to the two independent cavities (4) and have the lenses (1) mounted therein.

Virtual reality headsets capable of accommodating display devices of a plurality of shapes and sizes are provided herein. In a first embodiment, the virtual reality headset may include a buckle, a fastening engagement face, and an elastic strap with a fastening mechanism on a distal end. The elastic strap may be configured to be threaded through the buckle and the fastening mechanism may be configured to be detachably attached to the fastening mechanism engagement face to secure a display device to the virtual reality headset. In a second embodiment, the virtual reality headset may include a first fastening stud, a second fastening stud, and an elastic strap with a first line of holes and a second line of holes. The first and second lines of holes may be configured to be secured, respectively, to the first and second fastening studs to secure a display device to the virtual reality headset.

A three-dimensional imaging system based on a stereo hologram is disclosed. Images composed of sub-images having the same vertical-horizontal resolutions which are generated at plural image projection modules having a two-dimensional arrangement structure are projected to a prism array plate or a transmission-type diffusion plate, and are converted into light points, i.e., image points through a microlens array unit. A diffusion plate used as an image display screen is mounted to a position at which images diffused from the light points intersect with images diffused from the adjacent light points.

A system for rendering three-dimensional image content for a multi-focal display device. The system includes a first processing sub-system configured to divide the three-dimensional image content into a plurality of virtual depth planes, associate each of the plurality of virtual depth planes with one of a first set of displays and a second set of displays of the multi-focal display device, and generate a first array including the plurality of virtual depth planes. The system also includes a transmission sub-system configured to provide a data channel for transmission of the generated first array. The system further includes a second processing sub-system configured to receive the generated first array and to render the three-dimensional image content in the multi-focal display device based thereon.

A side-edge backlight module having non-uniformly sized backlight sections includes backlight sections that have relative sizes satisfying the condition that the backlight sections have higher ranks are of greater sizes. Ranking the backlight sections is made by conducting an simulation operation for a process of sectionalized lighting of backlight to display liquid crystal panel signals on the basis of uniformly sized backlight sections and conducting analysis of the number of zones where an interference signal appears and distance of the interference signal when each of backlight sections is lit in the simulation operation on the basis of uniformly sized backlight sections and ranking the backlight sections according to strength of cross-talking caused by the interference signal so that a backlight section having less strong cross-talking is set with a higher rank.

A three-dimensional holographic display device includes a light emitting diode (LED) array including a plurality of light sources controlled to sequentially output light according to a preset pattern, a lens configured to refract light incident from the LED array, a spatial light modulator (SLM) configured to modulate light incident from the lens, and a processor configured to generate a plurality of holographic signals each comprising depth information adjusted according to an arrangement location of each of the plurality of light sources, and for each of the plurality of light sources, control the SLM to modulate the light based on a holographic signal corresponding to the light source.

A foldable virtual reality viewer for use with smartphone devices is provided. The viewer is configured to be transitioned between a collapsed state to an expanded, operative state. The viewer comprises a housing configured to receive a mobile device therein. In order to facilitate transitioning the viewer between the flat and operative states, a main body of the viewer comprises a substrate having a series of panels defining a top, bottom, left and right walls and folds between adjacent panels in the series. The series of panels are attached at ends thereof to define a collapsible sequence of panels/walls that bound an interior volume of the viewer. In addition, a faceplate is attached to an interior surface within the main body such that it pivots within the interior when transitioning the viewer between the expanded state and the collapsed state.
