主权项

1. A liquid crystal driving device which drives a passive liquid crystal display apparatus, comprising:
a common electrode driving section which scans a common electrode of the liquid crystal display apparatus while interlacing every predetermined number of interlaced lines, the predetermined number of interlaced lines being a natural number greater than one; a segment electrode driving section which drives a segment electrode of the liquid crystal display apparatus on the basis of image data corresponding to the common electrode scanned by the common electrode driving section; and a polarity reversion control section which performs control for reversing polarity of a voltage between the common electrode scanned by the common electrode driving section and the segment electrode driven by the segment electrode driving section, every predetermined number of polarity reversion lines, the predetermined number of polarity reversion lines being a natural number greater than one, the polarity reversion control section outputting a polarity reversion signal on the basis of the predetermined number of polarity reversion lines, the common electrode driving section reversing a polarity of a common voltage of the common electrode based on the polarity reversion signal, the reversing of the polarity of the common voltage performed with a non-constant interval of a common address corresponding to the common electrode, and the segment electrode driving section driving a segment voltage of the segment electrode such that the segment voltage is changed based on the image data and the polarity reversion signal.
