  • Publication number: 20110169929
    Abstract: A video display system includes a video display unit time-divisionally performing switching between a plurality of video streams to display the video streams, thereby emitting linear polarized display light; and shutter eyeglasses performing switching between open state to transmit incident light and closed state to block the incident light in synchronization with the switching between the video streams in the video display unit, each eyeglass in the shutter eyeglasses including a liquid crystal device, an entrance-side polarization plate provided on a light entrance side of the liquid crystal device and an exit-side polarization plate provided on a light exit side thereof. Polarization degree in the entrance-side polarization plate is lower than that in the exit-side polarization plate.

  • Publication number: 20100295929
    Abstract: Described herein are circuits and methods enabling a user to view 3D video using shutter glasses. The shutter glasses can wirelessly receive a video synchronization signal to synchronize the timing of a shutter operation with the timing of displayed video. A self-timing signal can be generated based on a measured period of the video synchronization signal. A low-power mode of operation can be entered for a period of time in which reception of the video synchronization signal is disabled and the shutter operation is controlled based on the self-timing signal.
