    Abstract: Stereoscopic eyewear with compound curvature may be employed to view three dimensional content. The manufacture of such eyewear may be achieved by thermoforming a first material and by thermoforming a second material. The first and second materials may be in roll stock form prior to thermoforming, and the first layer may be polarizer material, while the second layer may be retarder material. Each of the first and second materials may be thermoformed by employing optimized thermoforming conditions for each of the two materials. Additionally, the two thermoforming lines may be timed so that the curved shapes of the first material in roll stock form may be substantially synchronized with the curved shapes of the second material in roll stock form, which may allow the curved shapes of each of the first and second materials in roll stock form may be joined together.

  • Patent number: 8427746
    Abstract: The present invention discloses a stereoscopic image display system and a method of controlling the same. An eye tracking module locates current 3D spatial positions of the viewer's eyes, and generates the information of both left and right eyes' current 3D spatial positions. A control module controls a display device that can alter the direction of the light outputted, and outputs images on the display device in time multiplex mode. The light containing the left eye image is outputted to the position of left eye instead of right eye at one time point, and the light containing the right eye image is outputted to the position of right eye instead of left eye at another time point, so that a stereoscopic image is perceived according to the parallax theory. The present invention enlarges the visual range of stereoscopic image and achieves a better stereoscopic image visual experience for viewers.

    Abstract: Disclosed herein are displays and related methods for providing stereoscopic imagery, wherein an air gap may be provided between components of the display to allow a reduction in the amount of bonding material used to bond a stereoscopic display panel with a polarization control panel (PCP) element comprising an active switchable retarder. In some embodiments, the PCP element is at least the size of the display panel such that the entirety of the display panel is covered by the PCP element, and thus there would be neither tight tolerance horizontal nor vertical alignment requirements between the PCP element and the display panel. Structural support of the components of the display may be provided by bonding around the edges of the rigid or semi-rigid stereoscopic display panel and PCP element. For example, the air gap may be created with uniform spacers between the stereoscopic display panel and the PCP element.

    Abstract: Systems and methods configured for outputting light having a polarization state distribution that is spatially uniform by applying a correction to, for example, a beam of light with a spatially uniform polarization state distribution that has been altered (unintentionally or otherwise) to become spatially non-uniform are described. A projection system can include an optical element and a polarization-altering device (PAD). The optical element can cause a polarization of light in the projection system to be spatially non-uniform. The PAD can change the polarization state distribution of the light spatially based on an amount of spatial non-uniformity on the light caused by the optical element and before the light enters the optical element. The projection system can output the light having a spatially uniform polarization state distribution.
