Method for driving a liquid crystal display apparatus and driving circuit therefor

摘要

Method for driving LCD device comprises step of: applying one of upper image signal outputted from an upper liquid crystal drive circuit and lower image signal outputted from a lower liquid crystal drive circuit to a plurality of pixels of a selected line by scanning signal outputted from a scanning signal circuit out of the plurality of pixels disposed in matrix to display a predetermined image; wherein there exist in mixture a case where the polarities of the upper image signal and the lower image signal are inverted every one vertical period and a case where the same polarity is maintained. The driving circuit of LCD device of the present invention includes a vertical synchronization signal converting circuit so as to obtain upper image signal and lower image signal.
