  • Patent number: 11281020
    Abstract: A multi-view display is switchable between single view and multi-view modes, and uses lenticular means (9) arranged over the display panel which comprise birefringent electro-optic material (62) adjacent a non-switchable optically transparent layer (60). The non-switchable optically transparent layer (60) has a refractive index (n) substantially equal to the extra ordinary refractive index of the birefringent electro-optic material (62). In the single view mode, the birefringent electro-optic material (62) defines a non-switched state, and the polarization (64) of the light output from the display panel and incident on the lenticular means is linear and aligned with the optical axis of the birefringent electro-optic material (62) at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material (62) defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.

    Abstract: 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.

  • 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.
