  • Patent number: 8432436
    Abstract: An interactive, autostereoscopic system for displaying an object in 3D includes a mirror configured to spin around a vertical axis when actuated by a motor, a high speed video projector, and a processing system including a graphics card interfaced to the video projector. An anisotropic reflector is bonded onto an inclined surface of the mirror. The video projector projects video signals of the object from the projector onto the inclined surface of the mirror while the mirror is spinning, so that light rays representing the video signals are redirected toward a field of view of a 360 degree range. The processing system renders the redirected light rays so as to interactively generate a horizontal-parallax 3D display of the object. Vertical parallax can be included in the display by adjusting vertically the displayed views of the object, in response to tracking of viewer motion by a tracking system.

  • Publication number: 20130050452
    Abstract: A new beam deflection approach is provided for displaying images in autostereoscopic format. Conceptually, polarized light from a display is directed into specific viewing regions using a polarization-sensitive beam deflection sub-system that comprises, in exemplary embodiments, an active liquid crystal quarter-wave plate modulator and a passive cycloidal grating element, such as a diffractive waveplate. Specific embodiments may comprise an illumination system that both floods an LCD panel and creates a defined eye pupil region, from within which the display is viewable. Deflecting the pupil region between left and right eye positions in synchronization with displayed frame sequential stereo image data creates desirable autostereoscopic 3D viewing. Other embodiments employ a similar beam deflection sub-system in conjunction with a means of viewing subsets of pixels from different viewing positions, such as a parallax barrier or lenslet array, allowing freedom of head movement while maintaining stereo viewing.

  • Publication number: 20130033588
    Abstract: Pixels belong to any of a plurality of pixel groups. The pixel groups each include first pixels and second pixels. A three-dimensional image display apparatus polarizes light to be emitted from the first pixels into light having a first polarization characteristic and polarizes light to be emitted from the second pixels into light having a second polarization characteristic. The three-dimensional image display apparatus, sets luminance of at least one of luminance of a left-eye image or luminance of a right-eye image such that the luminance of a predefined first image of the left-eye image or the right-eye image is higher than the luminance of a second image of the images. The three-dimensional image display apparatus causes the first pixels to render the first image at the set luminance on a screen and causes the second pixels to render the second image at the set luminance on the screen.

  • Patent number: 8199070
    Abstract: A method and system for use in conjunction with a push-pull liquid crystal modulator system for creating circularly polarized light of alternating handedness is provided. The method and system comprise a pair of surface mode liquid crystal cells and a driver electrically coupled to the cells. The driver is configured to move an electrical charge using a quenching pulse comprising a relatively brief voltage spike at a beginning of a waveform period. Multiple additional improvements are provided, including reducing the thickness of the LC gap (the distance between cell electrode plates), creating a charge connection or wiring connection to the cell electrodes, employing anti-reflection coating technology, thinner ITO and ITO index matched to the LC material, bonding all possible air to material surfaces, using superior glass, employing more efficient polarizers, and reducing projector blanking time.

    Abstract: Right and left eye images constituting each frame image are displayed on odd and even horizontal lines, or even and odd horizontal lines, respectively, of a display screen of a liquid crystal display. When the display switches from one frame to the next, the right and left eye images are switched between the odd and even horizontal lines, or the displayed right and left eye images are overwritten with the same images, so that the right and left eye images are interlaced with each other. Each time the right and left eye images are switched between the odd and even horizontal lines, the lighting state of the backlight is adjusted and the right and left sides of the polarized glasses are switched between two retarding states so that the right side is in one retarding state, the left side is in the other retarding state, and vice versa.
