Abstract:
1. A driving method for increasing gray level, applying to an FRM (Frame Rate Modulation) display panel, the method comprising: dividing the section of the horizontal synchronous signal of a frame interval into multiple sub-sections, adding a PWM (Pulse Width Modulation) mode, and implementing said PWM mode with the common drive circuit; wherein said PWM mode allocates said turn-on sub-sections of a frame to neighboring non-turn-on frames whereby said original continuous turn-on sub-sections are weighted and dispersed to said neighboring non-turn-on frames, the turn-on sub-sections are continuous for the neighboring pixels on neighboring common electrodes and along an identical segment electrode, and said non-turn-on sub-sections are continuous for the neighboring pixels on neighboring common electrodes and along an identical segment electrode, the switching frequency of said pixels being thereby reduced.
