The invention discloses a three-dimensional display method for large field of view and small viewing-zone interval. A display screen constructed by sub-screens with adjacent ones emitting lights of different exclusive optical characteristics is employed, and sequentially-switching aperture-arrays are placed close to a pupil of the viewer. M apertures of an aperture array correspond to the M sub-screens by a one-to-one manner in turn, to make the transmittance of each aperture to the light from the corresponding sub-screen be greater than that to the lights from the adjacent non-corresponding sub-screens by a ratio larger than 9. The corresponding apertures of a sub-screen in different aperture-arrays are arranged with an interval not larger than the diameter of the pupil. At a time-point, only one aperture-array gets open, and all aperture-arrays get open sequentially at different time-points of a time-period. At each time-point, each sub-screen presents optical information to the corresponding turned-on aperture synchronously. When the time-period is small enough, a three-dimensional display with large field of view and small viewing-zone interval gets implemented.

A multiview display, system and method includes an array of light valves having a repeating plurality of color sub-pixels and arranged as a plurality of multiview pixels configured to modulate directional light beams as color pixels of views of a multiview image, and an array of multibeam emitters configured to provide the directional light beams. A location of a multiview pixel relative to a location of color sub-pixels is configured to be shifted as a function of a position of a user of the multiview display to provide dynamic color sub-pixel remapping.

A three-dimensional (3D) projector includes a 3D display device and a camera. The 3D display device includes a backlight, a display including a display surface, a barrier, and a controller. The camera has an imaging direction that may be a direction of the image light emitted from the display or may be different from the direction of the image light. With the imaging direction of the camera being different from the direction of the image light, the controller performs a process to correct distortion on a captured image output from the camera with reference to the direction of the image light.

A light source, a light source assembly, a display device and a display method. The light source comprises a first light emitting region and a second light emitting region. The first light emitting region and the second light emitting region can control ON or OFF of the light emission separately. The first light emitting region and the second light emitting region are arranged alternately along a first direction. The first light emitting region and the second light emitting region of the light sources in this disclosure can be controlled separately. Hence, one light emitting region can be made to emit light while the other light emitting region can be made to be turned off. There is no stray light in the turned-off light emitting region, so as to avoid stray light crosstalk to light of the other light emitting region.

A display device has a display panel for displaying a composite image to allow a viewer to see a 3D image. The composite image has a plurality of right and left image strips alternately arranged. The display device also has camera to monitor a viewing position of a viewer. The camera has a camera lens and a sensor with a plurality of right sensor zones and left sensor zones to capture the viewer's right eye and left eye images. When the viewer is at a viewing position that the 3D image viewed by the viewer appears pseudostereoscopic, the viewer's right eye image is in one of the left sensor zones and left eye image is in one of the right sensor zones. A processor changes the order of the right and left image strips so that the viewer can see a orthostereoscopic image at that viewing position.

The present application provides a viewpoint controllable three-dimensional image display apparatus. The viewpoint controllable three-dimensional image display apparatus includes a display panel having a light emitting side; a back light for providing a light source for image display in the display panel; a first grating on a side of the light emitting side distal to the back light; a second grating between the display panel and the back light; and a controller configured to alternately turn on and off the first grating and the second grating in a time-division driving mode including a first mode and a second mode, thereby presenting a three-dimensional image to a user. In the first mode, the controller is configured to turn off the second grating, and turn on the first grating. In the second mode, the controller is configured to turn off the first grating, and turn on the second grating.
