Abstract: Generally, this disclosure concerns the angle sensitivity of polarization switch elements and the resulting impact of the ray direction on performance. More specifically, apparatus and techniques for compensating the angular sensitivity of liquid crystal (LC) polarization switches are described that enhance the performance of polarization switches. For example, a polarization switch is disclosed that transforms linearly polarized light of an initial polarization orientation that includes a first and second liquid crystal cell with a compensator located between the LC cells. The compensator layer is operable to enhance the field of view through the polarization switch. Such compensation techniques are particularly useful for short-throw projection environments.

Abstract: Shuttering eyewear (or shutter glasses) may be used to enable stereoscopic 3D and to provide different images to two viewers using a single display, known as Dual View. The shuttering eyewear may utilize charge recovery circuits. The charge recovery circuits may achieve high charge recovery efficiencies on the order of 80 to 90 percent resulting in a dramatic reduction in power supply battery operating current and a resulting increase in operating time. The charge recovery circuits may utilize switch mode boost conversion to recover most of the charge from a shutter that is being closed to one that is to be opened. Further, a charge recovery method for utilizing energy stored on a capacitive storage device may include closing a first active shutter, moving charge to a converter in buck mode to a capacitor, and pulling charge from the capacitor to open a second shutter.

Abstract: An active eyewear method and system for viewing stereoscopic images is provided. The eyewear comprises polarization altering elements, such as twisted nematics or super twisted nematics, configured to receive light energy and rotate the polarization of light energy passing therethrough, and linear polarizers having polarization axes oriented in substantially identical orientations orthogonal to the first axis of polarization. The linear polarizers receive light energy from the polarization altering elements. The method comprises transmitting light energy through a sheet polarizer having an first axis of polarization, receiving the light energy with two polarization altering elements, each polarization altering operating out of phase with the other and in synchrony with a video field rate associated with the transmitting, and passing the light energy through two linear polarizers having substantially identical axes of polarization orthogonal to the first axis of polarization.

Abstract: A device and method for converting one stereoscopic format into another. A software-enabled matrix is used to set forth predefined relationships between one type of format as an input image and another type of format as an output image. The matrix can then be used as a look-up table that defines a correspondence between input pixels and output pixels for the desired format conversion.

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.
