Abstract:
1. A method of displaying stereoscopic imagery on a flat panel display, the display having a backlight with a plurality of backlight illuminating segments operable to selectively provide light to a liquid crystal (LC) modulation panel, the LC modulation panel having LC modulation regions operable to modulate the light incident from the backlight, and a polarization control panel (PCP) operable to switch temporally between 1) transforming a state of polarization (SOP) of the modulated light incident from the LC modulation panel to a first SOP corresponding to one of a left eye image mode or a right eye image mode; and 2) transmitting the modulated light incident from the LC modulation panel with a second SOP corresponding to the other of the left eye or right eye image mode, the method comprising: controlling the PCP with one of left eye and right eye polarization control signals; providing the light to selected LC modulation regions from selected backlight illuminating segments, wherein the selected LC modulation regions comprise sufficiently settled modulation regions operating in an image mode corresponding to the one of left eye polarization control signals and right eye polarization control signals; and switching from controlling the PCP with the one of left eye and right eye polarization control signals to the other of the left eye and right eye polarization control signals, wherein during the switching, the backlight illuminating segments are not providing light.
