A 3D laser projection systems and methods are disclosed herein. A laser projection system includes a left projector head and a right projector head, wherein a first video projected onto a movie screen by the left projector head has a first polarization and a second video projected onto the movie screen by the right projector head has a second polarization different from the first polarization. The laser projection system can include a laser light generator located a first defined distance away from the left projector head and a second defined distance from the right projector head and coupled to the left projector head and the right projector head with fiber optic cables that transmit light from the laser light generator to the left projector head and the right projector head. The laser light generator includes a laser diode configured to output light and to transmit it to the fiber optic cables.

The invention features techniques and systems for presenting two or more perspective views to each eye of the viewer, through division multiplexing of the viewer's entrance-pupil. The system is constituted by a selective-aperture array with each aperture being transparent only to light beams with some special characteristics, at least one display screen for optical information presentation, and other optional elements. The optical message on at least one display screen propagates to the selective-aperture array directly, or be directed to the selective-aperture array or the eye of the viewer by other optional elements. Through selective filtering by the apertures with temporal filtering characteristics or exclusive filtering characteristics, multiple perspective views get presented to an eye of the viewer through the selective-aperture array. Light rays different perspective views superimpose into real spatial light spots that the eye can focus on naturally, resulting in overcoming of the accommodation-convergence conflict.

An autostereoscopic display includes a plurality of projectors and a screen. Each of the projectors is configured to provide a corresponding lamp image unit. Each of the lamp image units includes array of lamp images actuated in time sequence and projecting to different directions. The screen has an image plane and includes a first micro-lens array and a second micro-lens array. The first micro-lens array is configured to guide the lamp image units to the image plane such that the lamp image units are connected end to end and arranged in a ring on the image plane as a lamp image set. The second micro-lens array is located corresponding to the first micro-lens array and configured to magnify the projection angles of the lamp image units in the lamp image set and project the lamp image set to an observing surface.

A method and device for increasing a resolution for each viewpoint in a glassless three-dimensional (3D) display. A method of controlling a three-dimensional (3D) display device including a display panel and a lens includes performing time-division on a plurality of viewpoint images such that each of the viewpoint images is divided into n division images, transferring the division images to the display panel by increasing n times a frame rate of the division images, and controlling the lens such that the division images transferred to the display panel pass through a lens cell.

A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium having computer instructions to retrieve from a first high definition (HD) channel utilized for transporting two-dimensional media programs a first HD stereoscopic data stream, retrieve from a second HD channel utilized for transporting two-dimensional media programs a second HD stereoscopic data stream, and present a 3D HD imaging stream comprising the first and second stereoscopic data streams. Other embodiments are disclosed and contemplated.

A multi-view display device is provided, and the multi-view display device at least comprises a projector, a first lens set, and a second lens set. The projector contains a scan-lamp image, and the projector slants an incident ray corresponding to the scan-lamp image with a first angle. The first lens set receives the slanted incident ray and refracts that. The second lens set is slanted with the first angle, and the second lens set receives the slanted incident ray which is refracted by the first lens set and refracts that again, so as to expand a view area of the multi-view display device.

A 3D display device having a lens-switching function. The device includes an LCD picture layer, a lens-array plate, an LCD shielding pattern layer, and a synchronous picture providing system. The synchronous picture providing system is connected with the LCD picture layer and the LCD shielding pattern layer such that the LCD picture layer and the LCD shielding pattern layer are synchronous to respectively display a 3D picture and a shielded pattern. Through increasing an area of black shielding pattern, an edge of each lens unit corresponding to the shielding region is shielded, the area of a single light transparent region is reduced, and a light transparent aperture of a lens unit corresponding to the shielding region is reduced in order to eliminate a cross talk generated by scattering and bluntness at the edge.
