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.
Claims15
A system for displaying video images in response to each frame of field-sequential video signals, the system comprising:
- a backlight comprising a first primary color light source, a second primary color light source, and a third primary color light source,
- the backlight being operable to emit light for at most 5.56 milliseconds of each frame (on-time), and to emit no light during the remainder of each frame (off-time), wherein:
- during a portion of the on-time, at least two of the primary color light sources are on simultaneously, and for another portion of the on-time, the primary color light sources are on sequentially.
A method for displaying video images in response to each frame of field-sequential video signals, the method comprising:
- outputting light from three primary color light sources for at most 5.56 milliseconds during each frame of the video signals (on-time), and outputting no light during the remainder of each frame (off-time), wherein:
- during a portion of the on-time, at least two of the primary color light sources are outputting light simultaneously, and for another portion of the on-time, the primary color light sources are outputting light sequentially.
