ABSTRACT:
A system and method for displaying video images in response to each frame of field-sequential video signals. The system comprises a backlight comprising first, second and third primary color light sources. The backlight is operable to emit light for at most 5.67 milliseconds of each frame (on-time), and to emit no light during the remainder of each frame (off-time). During a portion of the on-time, at least two of the primary color light sources are on simultaneously. For another portion of the on-time, the primary color light sources are on sequentially.
