  • Patent number: 7345664
    Abstract: An improved stereoscopic display apparatus and methodology includes an array of reflective liquid-crystal-based pixels that are cleared (i.e., placed in a “dark” state) before being loaded with the desired analog voltage potential signals for display during both left perspective image display periods and right perspective image display periods. In this manner, cross-frame image interference between the left and right perspective images is avoided and the quality of the stereoscopic viewing experience is improved. In another aspect, an improved stereoscopic display apparatus and methodology includes a plurality of arrays of reflective liquid-crystal-based pixels. During each successive display period, the pixels of the arrays display an image while being loaded with analog voltage potential signals corresponding to the image to be displayed in the subsequent display period. Such operations avoid cross-frame image interference and expand the left and right perspective image display periods.

  • Patent number: 7345665
    Abstract: An improved stereoscopic display apparatus and methodology includes an array of liquid-crystal-based transmissive pixels are cleared (i.e., placed in a “dark” state) before being loaded with the desired analog voltage potential signal for display during both left perspective image display periods and right perspective image display periods. In this manner, cross-frame image interference between the left and right perspective images is avoided and the quality of the stereoscopic viewing experience is improved. In another aspect, an improved stereoscopic display apparatus and methodology includes an array of liquid-crystal-based transmissive pixels. During right perspective image display periods, the pixels of the array are loaded with analog voltage potential signals corresponding to a left perspective image while displaying the preceding right perspective image.

  • Patent number: 7345659
    Abstract: An improved stereoscopic display apparatus and methodology includes an array of OLED-based pixels that are cleared (i.e., placed in a “dark” state) before being loaded with the desired analog voltage potential signal for display during both left perspective image display periods and right perspective image display periods. In this manner, cross-frame image interference between the left and right perspective images is avoided and the quality of the stereoscopic viewing experience is improved. In another aspect, an improved stereoscopic display apparatus and methodology includes an array of OLED-based pixels. During right perspective image display periods, the pixels of the array are loaded with analog voltage potential signals corresponding to a left perspective image while displaying the preceding right perspective image.

  • Patent number: 5615237
    Abstract: A synchronizer for telecommunications signals includes a telecommunications interface for receiving bits of a telecommunications signal having a frame, an SRAM which stores bit-defined states for a plurality of bit locations in the frame, a state update lookup table for changing the states for a plurality of the frame bit locations of the SRAM based on a previous state and based on an incoming bit of the telecommunications signal, and frame location identification logic for determining the location of the overhead bit of the telecommunications signal frame based on the states of the plurality of bit locations. In a first embodiment, the SRAM is an x by y bit SRAM, where x equals the number of bits in the frame, and y is large enough so that the number of possible states .ltoreq.2.sup.Y.
