Abstract:
1. A driving circuit of a display panel, comprising: a positive signal generating unit, used for generating a positive-polarity signal; a first positive selecting circuit, coupled to said positive signal generating unit, comprising a first switch and a second switch, and said first switch and said second switch outputting said positive-polarity signal to a first output according a first switching signal and a second switching signal, respectively; a second positive selecting circuit, coupled to said positive signal generating unit and said first positive selecting circuit, comprising a third switch and a fourth switch, and said third switch and said fourth switch outputting said positive-polarity signal to a second output according a third switching signal and a fourth switching signal, respectively; a negative signal generating unit, used for generating a negative-polarity signal; a first negative selecting circuit, coupled to said negative signal generating unit, comprising a fifth switch and a sixth switch, and said fifth switch and said sixth switch outputting said negative-polarity signal to said first output according a fifth switching signal and a sixth switching signal, respectively; and a second negative selecting circuit, coupled to said negative signal generating unit and said first negative selecting circuit, comprising a seventh switch and an eighth switch, and said seventh switch and said eighth switch outputting said negative-polarity signal to said second output according a seventh switching signal and an eighth switching signal, respectively; where said first switch and said second switch, said third switch and said fourth switch, said fifth switch and said sixth switch, or said seventh switch and said eighth switch are both equivalent to diodes in the cutoff state, the voltage difference across said first switch and said second switch, said third switch and said fourth switch, said fifth switch and said sixth switch, or said seventh switch and said eighth switch to be divided by the diodes.
