Stereoscopic display system with active switchable retarder

摘要

Disclosed herein are displays and related methods for providing stereoscopic imagery, wherein an air gap may be provided between components of the display to allow a reduction in the amount of bonding material used to bond a stereoscopic display panel with a polarization control panel (PCP) element comprising an active switchable retarder. In some embodiments, the PCP element is at least the size of the display panel such that the entirety of the display panel is covered by the PCP element, and thus there would be neither tight tolerance horizontal nor vertical alignment requirements between the PCP element and the display panel. Structural support of the components of the display may be provided by bonding around the edges of the rigid or semi-rigid stereoscopic display panel and PCP element. For example, the air gap may be created with uniform spacers between the stereoscopic display panel and the PCP element.

主权项

1. A display for providing stereoscopic imagery, the display comprising:
a stereoscopic display panel operable to provide left-eye and right-eye image encoded light; a polarization control panel (PCP) element positioned to receive light from the stereoscopic display panel and having an active switchable retarder operable to selectively transform the state of polarization (SOP) of light received from the stereoscopic display panel in synchronization with the left-eye and right-eye image encoded light; and wherein the stereoscopic display panel is bonded to the PCP element with an air gap therebetween, the air gap substantially coextensive along both length and width of the stereoscopic display panel, further wherein the PCP element is larger in length and width than the stereoscopic display panel such that the entirety of the stereoscopic display panel is covered by the PCP element.
