This invention provides a color passive matrix bistable liquid crystal display system, in which one respective scan line corresponds to sub-pixels of same color and neighboring scan lines correspond to sub-pixels of different colors. The scan lines are grouped in accordance with the colors of the sub-pixels corresponding thereto such that different scan driving voltages can be provided to the sub-pixels of different colors when the scan lines are scanned. By way of the arrangement of the sub-pixels, different scan driving voltages are switched to the respective scan lines in accordance with the colors of the sub-pixels corresponding thereto. As a result, a demand that the sub-pixels of different colors require different scan driving voltages is satisfied. The image quality is improved.

Color passive matrix bistable liquid crystal display system and method for driving the same

A method and an apparatus for driving multi-segment display device are described. According to the present invention, problems of driving the electrode wire activation mode of the conventional liquid crystal display are solved by the driving waveforms. The driving waveforms of non-display area are in the OFF mode, where the non-display area has pixels in the OFF mode, driving electrode wires and background area. Problems of driving voltage wire activation mode are decreased, cost is lowered, and processing is simplified, so that every pixel of the display device will be controlled precisely.

The present invention provides a method for modulating backlight sources for flat panel displays (FPD), which comprises: lowing steps: step: turning on a display screen; step: identifying whether the total number of the BLL groups provided on the backlight module is an odd number or an even number; step: turning on the one BLL group located at the center-most region of the backlight module while the total number of the BLL groups is an odd number; step: turning on the two BLL groups located at the center-most region of the screen while the total number of the BLL groups is an even number; step: turning on the two backlight groups located at the two outer side of the center turned-on backlight groups while turning off the center turned-on backlight groups, and similarly, progressing the turning-on and the turning-off from the center region to the two outer edge of the backlight module and then reverse-progressing respectively from the two edges to the center region, so as to complete a full cycle; step: determining whether the display screen is off; if so, the process proceeds to step (); otherwise, the process goes to step (); and step: ending the process.
