A drive system for a projection screen in a swept surface volumetric 3D display is disclosed. The drive system causes the projection screen to reciprocate through an excursion distance at a screen reciprocating frequency relative to a projection system. The drive system includes an actuator arrangement for generating an input reciprocating force substantially at the screen reciprocating frequency through an input excursion distance and a support structure for the projection screen. The support structure includes a resonant mounting arrangement for the projection screen. The resonant mounting arrangement is operably connected to the actuator arrangement and configured to allow the projection screen to reciprocate through the excursion distance. The resonant mounting arrangement is configured to have a resonant frequency substantially equivalent to the screen reciprocating frequency on actuation of the actuator arrangement. A gaming console incorporating a swept surface volumetric 3D display based on the drive system is also disclosed.

An optical device includes a light-guiding plate and light sources that each emit light to the light-guiding plate. The light-guiding plate has light convergence portions, the light substantially converges at or scatters from a convergence point or line, and an image is formed by a collection of the convergence points or lines, and a light convergence portion causes light to be emitted in directions in which the light substantially converges in or scatters from a range including a point located a first distance apart from the emission surface, and a second light convergence portion causes light to be emitted in directions in which the light substantially converges in or scatters from a range including a point located a second distance, which is longer than the first distance, apart from the emission surface, and the number of first light convergence portions is higher than the number of second light convergence portions.

The present disclosure relates to a lens grate having a first substrate and a second substrate opposite to the first substrate, a first electrode layer on the first substrate, a resin layer on the first electrode layer, a second electrode layer on the second substrate, and a liquid crystal layer between the resin layer and the second electrode layer. One side of the resin layer facing toward the liquid crystal layer is configured with a plurality of concave spherical surfaces. By configuring the concave spherical surfaces, the thickness of the liquid crystal layer is gradually decreased along the direction from the center area to the rim area from regardless of the viewing directions, i.e., top-down, left-right, or slant, and thus the viewing angle is wide. With such design, the viewing angle of the 3D effect may be enlarged so as to enhance the 3D display performance.

A method of assembling a display device is proposed. The method includes: arranging an alignment imaging device over the lens layer, aligning a first alignment target of the display panel and a first alignment target of the lens layer, controlling the display panel to emit and obtaining the light passing through the lens layer with the alignment imaging device to form bright and dark stripes, arranging one or more second alignment targets on the display panel and adjusting the position of the lens layer so as to align the central line of a bright stripe in the bright and dark stripes to the second alignment targets, and adhering the display panel to the lens layer. By using the present disclosure, the precise alignment of the display panel and the lens layer is reflected rapidly. The yield rate increases. The three-dimensional display effect of the display device improves as well.

A display device includes a display unit in which pixels having first and second regions are arrayed in a matrix, the first region emitting first color light for displaying a stereoscopic image including images of a plurality of viewing points and the second region emitting second color light in order to display the stereoscopic image. A separation unit separates optically the images of the respective viewing points from each other so that the images of different viewing points are observed by different eyes of a viewer, wherein in a region on the display unit in which the image of a predetermined viewing point is displayed, widths of the first and second regions in a parallax direction of the stereoscopic image are approximately the same and widths of the first and second regions in a vertical direction, which is approximately perpendicular to the parallax direction, are different.

Technologies are generally described herein for a mirror array display system. In some examples, a controller can be configured to execute various methods for displaying content using a mirror array display having a mirror array including a number of mirrors and a light source. The controller can obtain content for display. The controller can also determine at least one aiming parameter associated with the number of mirrors and the light source. The controller can also emit light using the light source and aim the light emitted by the light source to a convergence point to generate a three-dimensional representation of the content, wherein the light is aimed in accordance with the at least one aiming parameter.

Systems and methods herein are directed to providing a visual effect background that may be added behind a transparent holographic projection screen (e.g., of a Pepper's Ghost Illusion system) that provides for greater scenic depth behind the holographic projection, regardless of the amount of actual physical space behind the transparent screen. The background, which may be used for projection-based holographic projections or video panel display projections, generally establishes an optical illusion of depth behind the holographic images (producing a depth perception or “perspective” that gives a greater appearance of depth or distance behind a holographic projection).

A naked eye 3D display device is provided. The naked eye 3D display device includes a directional projection screen, a laser light source, a red monochromatic laser light source, a green monochromatic laser light source and a blue monochromatic laser light source. Lights emitted by the three monochromatic laser light sources emit incident light on the directional projection screen with nano-grating pixels at specific angles and specific positions, and the same emergent light fields are formed. The laser light source provides multi-perspective image pixels. The multi-perspective image pixels match a nano-grating pixel array on the directional projection screen. By a direct spatial modulation for the laser projection light, colorful 3D display is achieved. There is no crosstalk between various viewpoints. The naked eye 3D display device has no visual fatigue and has a low cost.

Lenticular products and methods of manufacturing. A lenticular product can include a lenticular sheet having a front surface and a back surface, the front surface including an array of lenticular lenses. Images can be printed on the back surface of the lenticular sheet, and each of the images can be arranged into frames interlaced with other frames corresponding to other images, wherein each of the frames is aligned with a lenticular lense such that light reflected from frames associated with a same image are refracted in a same direction and frames reflected from frames associated with a different image are refracted in a different direction. The lenticular can include a backing layer having a first surface coupled to the back surface of the lenticular sheet and a second surface opposite of the first surface. The backing layer can include instructions and/or images on the second surface representing a sports move.

A system for capturing horizontal disparity stereo panorama is disclosed. The system includes a multi surface selective light reflector unit, a secondary reflector and a computing unit. The multi surface selective light reflector unit (a) obtains light rays from a 3D scene of outside world that are relevant to create (i) a left eye panorama and (ii) a right eye panorama and (b) reflects the light rays without internal reflections between the light rays. The secondary reflector (a) obtains the reflected light rays from the multi surface selective light reflector unit and (b) reflects the light rays through the viewing aperture. The computing unit captures (i) the reflected light rays from the secondary reflector and (ii) the upper part of the 3D scene from a concave lens as a warped image and processes the warped image to (a) the left eye panorama and (b) the right eye panorama.
