Precision multi-view display
A precision multi-view (MV) display system can accurately and simultaneously display different content to different viewers over a wide field of view. The MV display system may include features that enable individual MV display devices to be easily and efficiently tiled to form a larger MV display. A graphical interface enables a user to graphically specify viewing zones and associate content that will be visible in those zones in a simple manner. A calibration procedure enables the specification of content at precise viewing locations.

LIGHT FIELD IMAGE PROJECTION METHOD
A direct projection light field display comprising an array of projectors for direct projection of a light field. The overall design and incorporation of additional optics achieve the optimal light distribution and small pixel size to produce a high definition, 3D display. The architecture of the direct projection light field display has low a brightness requirement for each projector, resulting in an increased projector density, decreased system, and a decreased power requirement, while producing a high-definition light field.
Stereoscopic image display device capable of reducing grid visual effect
A stereoscopic image display device capable of reducing grid visual effect includes a flat display unit, a light source unit disposed on a side of the flat display unit, and a lens array unit disposed on another side of the flat display unit. A light source provided by the light source unit satisfies an optical characteristic as follows: an attenuation amplitude of a luminance of the light source before entering the lens array unit being not greater than 65% within a divergence angle of a light field system of the stereoscopic image display device, thereby reducing the grid visual effect of a stereo image generated by the stereoscopic image display device.

Light field displays incorporating eye trackers and methods for generating views for a light field display using eye tracking information
A multiview autostereoscopic display includes a display area including an array of angular pixels, an eye tracker, and a processing system. Each angular pixel emits color that varies across a field of view of that angular pixel. The array of angular pixels displays different views in different viewing zones across the field of view of the display. The eye tracker detects the presence of the eyes of at least one viewer within specific viewing zones and produces eye tracking information including locations of the detected eyes within the specific viewing zones. The processing system renders a specific view for each detected eye based upon the location of the detected eye within the viewing zone with detected eyes, and generates control information for the array of angular pixels to cause the specific view for each detected eye to be displayed in the viewing zone in which that eye was detected.
SYSTEMS AND METHODS FOR PROJECTING IMAGES FROM LIGHT FIELD DISPLAYS BASED ON POSITIONAL TRACKING DATA
Systems and methods presented herein include light field displays configured to display primary autostereoscopic images and to simultaneously project light rays toward display devices (e.g., either reflective devices or cameras) to display secondary autostereoscopic images via the display devices. The light rays projected from the light field displays are controlled by a control system based at least in part on positional tracking data (e.g., position, orientation, and/or movement) of the display devices and/or of a portion of humans associated with the display devices, which may be detected via sensors of the display devices and/or via cameras disposed about a physical environment within which the display devices and the humans are located. Specifically, the control system calculates light field vector functions for light rays to be projected toward each individual display device based at least in part on positional tracking data for that particular display device and/or its associated human.
SYSTEMS AND METHODS FOR PROJECTING IMAGES FROM LIGHT FIELD DISPLAYS BASED ON REFLECTED LIGHT RAYS
Systems and methods presented herein include light field displays configured to display primary autostereoscopic images and to simultaneously project (e.g., in real time, while displaying their own primary autostereoscopic images) light rays toward display devices (e.g., either reflective devices or cameras) to display secondary autostereoscopic images via the display devices. The light rays projected from the light field displays are controlled by a control system based at least in part on positional data (e.g., position, orientation, and/or movement) of the display devices, which may be determined by the control system based at least in part on detection of light rays that are reflected off the display devices.
LIGHT FIELD DISPLAY METHOD AND SYSTEM, STORAGE MEDIUM AND DISPLAY PANEL
A light field display method includes: generating a pixel light field information database (S1); processing, according to different depth positions of an original three-dimensional image, slice images corresponding to the different depth positions and pixel light field information at the different depth positions, to obtain recorded images of the slice images of the original three-dimensional image at the different depth positions (S2); and superimposing the recorded images of the slice images of the original three-dimensional image at the different depth positions, to obtain a microcell array image of the original three-dimensional image (S3). A light field display system has a database generator (101), a recorded image generator (102), and a superimposer (103) which implement the described functions. A non-transitory computer readable storage medium stores thereon a computer program for implementing the method. A display panel includes the non-transitory computer readable storage medium.
METHOD AND SYSTEM FOR CONTINUOUS CALIBRATION OF A 3D DISPLAY BASED ON BEAM STEERING
Some embodiments of an apparatus may include: a tracking module configured to track viewer movement adjustments; and a light field image display structure configured to display a light field image using the viewer movement adjustments. Some embodiments of a method may include: projecting a beam spot on a viewer of a light field display; determining an estimated location of the beam spot reflected off the viewer; detecting an actual location of the beam spot reflected off the viewer; and determining image correction parameters based on a comparison of the estimated location and the actual location of the beam spot reflected off the viewer.
