ABSTRACT:
Exemplary embodiments of the present invention provide an image rearranging unit that synthesizes an input image with a delayed signal thereof and arranges an image having 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 thereby obtain a write image. The scanning driver selects n scanning lines spaced apart from each other in one horizontal period of the input image and drives pixels with image signals having the same polarity between most adjacent lines. Thus, a horizontal electric field can be reduced or prevented by a plane inversion driving. Adjacent to a blanking period having a polarity, a write operation by an image signal having an opposite polarity is performed. 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 image signal is not affected by a high black level ghost. As a result, display quality can be reduced or prevented from deteriorating.
