摘要： When a frame rate is doubled by repeating video signals of respective frames twice and then resultant video signals are supplied to the overdrive circuitry, the number of cases where the effect of overdrive is not sufficiently obtained is likely to increase undesirably. A double-speed conversion section inserts, between video signals of an N-1th frame and an Nth frame following the N-1th frame which are input video signals, an N-1th interpolation frame video signal at a signal level same as that of the N-1th frame video signal, and outputs resultant video signals at a frame rate twice as high as that of the input video signals. An interpolation frame correcting section corrects the N-1th interpolation frame video signal outputted from the double-speed conversion section, in accordance with the signal levels of the N-1th frame video signal and of the Nth frame video signal.

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，同时还将用于向液晶单元施加预定电压的非图像信号插入到液晶面板的空间中输入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。

摘要： An image display device includes: an interpolation phase generator that generates an interpolation phase on the basis of downsampling frame information representing a downsampling timing at which at least one frame image of the image signal is thinned, and an interpolation frame generator that generates an interpolation frame image corresponding to the interpolation phase. The interpolation phase generator generates the interpolation phase such that a phase distance between a first interpolation frame image from among a plurality of interpolation frame images within one period of downsampling periods, and a second interpolation frame image that follows the first interpolation frame image becomes equal to a phase distance between mutually adjacent interpolation frame images obtained when phase distances between a plurality of interpolation frame images are equalized within one period of the downsampling periods.
