1. A display apparatus comprising: means for receiving at least one video signal representing a sequence of image pairs including a left perspective image and a right perspective image; at least one array of reflective liquid-crystal-based pixels; means for deriving a first set of analog voltage signals for the pixels of said at least one array in accordance with corresponding portions of said at least one video signal representing a left perspective image; means for clearing a given pixel of said at least one array before loading a corresponding one of said first set of analog voltage signals into the given pixel for display during a left perspective image display period; means for deriving a second set of analog voltage signals for the pixels of said at least one array in accordance with corresponding portions of said at least one video signal representing a right perspective image; and means for clearing the given pixel of said at least one array before loading a corresponding one of said second analog voltage signals into the given pixel for display during a right perspective image display period.
