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 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.
摘要翻译：信号转换部分增加要提供给液晶面板的输入图像信号的传送速率，并且同时在输入的空间中插入用于向液晶单元施加预定电压的非图像信号图像信号并将其作为图像元素信号提供给源驱动器。对于每个图像单元，输入图像信号和非图像信号被顺序地写入正极性或负极性。对于所有图像元素，在写入输入图像信号之后，总是写入与输入图像信号极性相等的非图像信号。此外，在非图像信号被写入之后，总是写入与非图像信号极性相反的图像信号。因此，当以OCB模式在液晶面板上显示图像时，可以防止反向转换的发生并且均匀地进行图像显示。
