摘要： A signal converting section increases a transfer rate of an input image signal to be supplied to a liquid crystal panel and, at the same time, also inserts a non-image signal for applying a predetermined voltage to liquid-crystal cells in a space of the input image signal and supplies it as a picture-element signal to a source driver. To each picture cell, an input image signal and a non-image signal are sequentially written with positive or negative polarity. For all picture elements, after the input image signal is written, the non-image signal equal in polarity to the input image signal is always written. Furthermore, after the non-image signal is written, an image signal opposite in polarity to the non-image signal is always written. Thus, when an image is displayed on the liquid crystal panel in OCB mode, it is possible to prevent the occurrence of back transition and carry out image display evenly.

摘要： A frequency converting section (101), which is included in a liquid crystal display apparatus, generates an output video signal by inserting one non-image signal, which is to be concurrently written into pixels on L (L is an integer equal to or greater than two) gate lines of the liquid crystal panel, for one line, between image signals composing an input video signal, for corresponding L lines, and adjusting a number of horizontal scanning periods of the output video signal in a vertical blanking period so that a number of horizontal scanning periods composing one frame period is (L+1)×(2N+1) (N is an integer). Thus, when anti-back-transition driving is performed using a liquid crystal panel in OCB mode, it is possible to minimize increase in a driving frequency, prevent irregularity of brightness caused by AC driving of the liquid crystal panel, and reduce a cost.
