Abstract
A segmented polarizing device may be a polarizing modulator which may include strips of switching polarizer material. The switching polarizer material may be used to switch individual segments of the polarizing modulator at a time. In such devices, the polarizing modulator may be one or more liquid crystal cells (LC cell). As the LC modulation panel of a display refreshes an image from top to bottom, changing from left eye content to right eye content, the polarization of a corresponding part of a scrolling polarizing screen may change along with the display.
