A method of displaying stereoscopic imagery on a flat panel display, the display having a spatially controllable backlight with a plurality of illuminating portions operable to selectively provide light to a liquid crystal (LC) modulation panel having modulation regions, and a polarization control panel (PCP) having a plurality of polarization control segments associated with the modulation regions, the polarization control segments being operable to selectively transform the state of polarization (SOP) of modulated light incident from the modulation regions, the method comprising:
- addressing data lines in a selected modulation region on the LC modulation panel with left eye image data;
- providing polarization control instructions to a polarization control segment associated with the selected modulation region, to operate in a left eye polarization display mode when a portion of the data lines in the selected modulation region display a predetermined portion of the left eye image frame;
- and
- providing the light to the selected modulation region from one or more selected illuminating portions, wherein the selected modulation region comprises a settled modulation region presenting image data corresponding to the left eye polarization control instructions.
