Claim Text:
1. A polarity inversion signal converting method, comprising: judging whether a preset number of frames of images with all-white picture or all-black picture are received continuously; and generating the judgment result indicating that the polarity inversion signal is required to be converted currently, when the preset number of frames of the images with all-white picture or all-black picture are received continuously and the polarity inversion signal currently output to the data driver is a first polarity inversion signal, adjusting the first polarity inversion signal currently output to the data driver as a second polarity inversion signal, when the judgment result indicates that the polarity inversion signal is required to be converted currently, wherein a power consumption generated by the data driver in a polarity driving manner corresponding to the second polarity inversion signal is lower than that generated by the data driver in a polarity driving manner corresponding to the first polarity inversion signal, the polarity driving manner corresponding to the second polarity inversion signal is a column polarity driving manner.
