A flat-panel display device 500, 600 with an active array of parallel longitudinal row backlights 520, 620 disposed in a first plane is disclosed. The row backlights sequentially emit a row of light for a fixed-duration row-interval of time t in successive row periods of duration p. Each row is illuminated once in each frame. The flat panel display device also has an array of longitudinal parallel liquid-crystal column shutters 531, 631 disposed in a second plane parallel to the first plane. The column shutters are oriented orthogonally to the row backlights so as to define pixels at each intersection of a column shutter and a row backlight. A driver 590, 690 is provided for causing the column shutters to make, at most, one transition from the "off" state to the "on" state or vice-versa every row period.
