Apparatuses can include a rotatable structure, motor, and multiple light field sub-displays disposed on the rotatable structure. The apparatuses can store a light field image to be displayed, the light field image providing multiple different views of the object at different viewing directions.

A device for time-based multiplexing of a projection of a three-dimensional FIG. 1 image to increase its resolution includes a two-dimensional display comprising an array of pixels. An array of optical elements is placed in front of the pixels.

The present invention relates to a method for displaying an image in a direction towards an observer observing the image from a viewpoint. The method comprises providing a display system including a tracking system for tracking or detecting the position of the observer, a display screen having a plurality of image pixels for displaying the image, a controller for controlling the direction of light emitted from said display screen, and a processing unit for generating a buffer image from a data source. The method further comprises tracking the observer and generating tracking data to the processing unit, generating the buffer image and embedding the tracking data as embedded data in the buffer image, outputting the buffer image to the display screen and displaying the image on the display screen, and reading the embedded data by the controller and directing light from the display screen in a direction towards the viewpoint.

The invention discloses a display module with the divergence angle of an outgoing beam constrained again by the corresponding deflection aperture, which includes a multi-view display structure, a deflection-aperture array and a control device. The multi-view display structure includes a display screen, a light-splitting device, and a backlight-source assembly for providing backlights when a backlit-type display screen is adopted. The light-splitting device guides light beams from each group of pixels or sub-pixels to the corresponding viewing zone. A deflection aperture with a small size is designed for constraining the divergence angle of deflected light beams. Multiple deflection apertures play the function of enlarging the field of view, which is very limited when only a single deflection aperture exists. With orthogonal characteristics being assigned to deflection apertures for suppressing noise and/or for projecting more views, three-dimensional display with natural focus will get implemented with large field of view and low noises.

A light filed (LF) display system for displaying holographic content (e.g., a holographic film or holographic content to augment a film) to viewers in a cinema. The LF display system in the cinema includes LF display modules tiled together to form an array of LF modules. The array of LF modules create a holographic object volume for displaying the holographic content in the cinema. The array of LF modules displays the holographic content to viewers in viewing volumes. The LF display system can be included in a LF film network. The LF film network allows holographic content to be created at one location and presented at another location. The LF film network includes a network system to manage the digital rights of the holographic performance content.
