    Abstract: A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. Several modes of operation may be provided including an advanced 2D mode, and an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters. Another embodiment may be an optical structure for a multi-functional LCD display with wide color gamut and high stereo contrast. The optical structure may also be used to produce more saturated colors for a wider display color gamut and also may be used to produce a brighter backlight structure through light recycling of the wider bandwidth light back into the optical structure.

    Abstract: The present application provides a single lens capture device having a single input port. The single lens capture device may include an objective lens, a fixed objective lens aperture, off-center apertures inside the objective lens, and a sensor. The sensor is operable to capture images at a rate of at least two times the rate of stereoscopic presentation.

    Abstract: Display devices with high dynamic ranges approaching the limitations of the human eye are discussed herein. High dynamic range projections systems may be 2D or 3D and devices may or may not be implemented with polarization preserving optics for high efficiency. In one embodiment, 2D HDR projection systems may compensate the modulator for varying transmission and contrast versus field of view. In another embodiment, 3D HDR projection systems may include a global or pixelated/segmented modulator. The global or pixelated/segmented modulator may be included in a stereoscopic polarization switch or in a polarization-preserving stereoscopic projection system. Additionally, a combination of global/global or pixelated/pixelated, or global/pixelated modulators may be used.

    Abstract: The present disclosure includes systems and methods for solving speckle problems by exciting the screen with a more complex vibration spectrum. A range of frequencies provides, in effect, a collection of overlapping patterns of high and low displacement, so that all regions of the screen have enough motion to reduce visible speckle. As previously discussed acceptable speckle may be approximately 15% contrast or less, preferably approximately 5% contrast or less at approximately 15 feet from the screen.

    Abstract: The present disclosure provides discussion of screen vibration to reduce speckle in display applications and/or projection screens. Electrical transducers or reactors may be used with a screen to reduce or remove speckle in projection screens and/or display applications. Electrical transducers may not be directly mounted to a screen, thus eliminating many mechanical failure modes associated with a vibrating transducer as well as resulting in a much quieter operation. By design, the reactors or transducers may actually contact the screen, and can take up less than one square inch of screen surface each, than previous designs, which may be outside of the active viewing area and within 12 inches of the screen border, preferably less than approximately 1 inch from screen edge. The reactors are magnets, though any ferrous material can be made to work with certain operating conditions.
