Abstract
A stereoscopic display and record component, more specifically a dual polarizing light filter, and the methods of applying the component for stereoscopic image displaying and stereoscopic image recording, are disclosed. A dual polarizing light filter may be statically or dynamically controlled to deliver or accept polarizing light of different orientations at different micro regions on the filter at different times. The invention may be used to create a new type display device and a new type of recording method for both 2-D and 3-D images. The component may be added to existing displays as well as integrated into the display fabrication process.
