    摘要: Systems and methods for providing an electrical waveform to a pi-cell polarization switch. The electrical waveform may reduce/limit ion accumulation in and/or light leakage associated with the polarization switch. The electrical waveform may include multiple segments, e.g., a first segment may drive the polarization switch to a first polarization state and may be defined by a first portion having a first voltage level and a first polarity and a second portion having the first voltage level and a second polarity opposite the first polarity and a second segment, occurring after the first segment, that may drive the polarization switch to the second polarization state. The second segment may be defined by a second voltage level having the first polarity. An absolute value of the first voltage level may be greater than an absolute value of the second voltage level.

    摘要: Systems and methods for calibrating a three dimensional (3D) stereoscopic display system may include rendering a virtual model on a display of a 3D stereoscopic display system that may include a substantially horizontal display. The virtual model may be geometrically similar to a physical object placed at a location on the display. A vertex of the virtual model may be adjusted in response to user input. The adjustment may be such that the vertex of the virtual model is substantially coincident with a corresponding vertex of the physical object.

    摘要: Modifying perspective of stereoscopic images provided by one or more displays based on changes in user view, user control, and/or display status. A display system may include a housing, a display comprised in the housing, and one or more tracking sensors comprised in the housing. The one or more tracking sensors may be configured to sense user view and/or user control position and orientation information. The one or more tracking sensors may be associated with a position and orientation of the display. The user view and/or user control position and orientation information may be used in generating the rendered left and right eye images for display.

    摘要: A voltage may be provided to a liquid crystal addressable element as part of a liquid crystal device. The provided voltage may be reduced from a driven state to a relaxed state in a time period greater than 1 μs. The reduction may further be performed in less than 20 ms. The liquid crystal device may be a polarization switch, which in some embodiments may be a multi-segment polarization switch. In one embodiment, pulses of limited duration of a light source may be provided to the polarization switch. The manner of voltage reduction may reduce optical bounce of the liquid crystal device and may allow one or more of the pulses of the light source to be shifted later in time.
