  • Patent number: 10701349
    Abstract: A multi-view display is display capable of simultaneously showing different images to viewers that see the display from different locations. Viewers do not see the images intended for other viewers at other locations. A multi-view display forms images via a collection of multi-view pixels, which are the devices that make such image customization possible. A multi-view pixel is able to emit different light in different directions; in each direction, parameters of emitted light such as brightness, contrast, etc., can be controlled independently of the light emitted in other directions. In order for the display to generate good-quality images, it is useful to perform a calibration of the display that will yield accurate information about the relationships of light emitted by multi-view pixels and locations where images are to be made viewable. Embodiments of the present invention provide calibrations that achieve the desired result efficiently and accurately.
