Abstract
A video signal of the non-interlaced scanning type is converted into a video signal of the interlaced scanning type by alternately selecting odd-number horizontal scanning line signals or even-number horizontal scanning line signals in synchronism with the start timing of each field period. The polarity of the video signal is inverted every vertical scanning period. During a first vertical scanning period, the odd-number video signal is written to respective sets of two neighboring line scanning electrodes (G,, G,), (G,, G,), (G,, G,), - - - . During a second vertical scanning period, the even-number video signal is written to another sets of two neighboring line scanning electrodes (G,, G,), (G,, G,), (G,, G,), - - - . The time axis of each horizontal scanning period is doubled. The drive frequency of a row signal electrode drive circuit is halved.
