摘要：Exemplary embodiments of the present invention provide an image rearrangingunit that synthesizes an input image with a delayed signal thereof and arranges an imagehaving a horizontal frequency n times larger than a horizontal frequency of the input

image in a signal arrangement according to scanning of a scanning driver, to therebyobtain a write image. The scanning driver selects n scanning lines spaced apart from eachother in one horizontal period of the input image and drives pixels with image signalshaving the same polarity between most adjacent lines. Thus, a horizontal electric field canbe reduced or prevented by a plane inversion driving. Adjacent to a blanking periodhaving a polarity, a write operation by an image signal having an opposite polarity isperformed. In this case, however, a low level blanking signal, for example, is also used,instead of a blanking signal. Thus, in the blanking period, the write operation of the imagesignal is not affected by a high black level ghost. As a result, display quality can bereduced or prevented from deteriorating.
