摘要： In one embodiment of the present invention, data, such as video signal data, for example, for a next desired frame is first modulated or varied to facilitate a transition from a current frame to a next desired frame. A modulation processing section can be used, for example, to thus produce a corrected video signal to facilitate the current-to-next desired grayscale level transition. Thereafter, spatial filtering is then carried on the corrected video signal, using a spatial filtering section for example. As such, high frequency components in a spatial domain may be reduced, even after the spatial frequencies of an ordinary video signal and potentially those of noise have been scaled up. Therefore, undesirable noise-caused display quality degradation can be reduced or even prevented, while pixel response speed as a result of the facilitation of grayscale level transition is increased.
摘要翻译：在本发明的一个实施例中，例如用于下一期望帧的诸如视频信号数据的数据首先被调制或变化，以便于从当前帧到下一个期望帧的转变。例如，可以使用调制处理部分来产生经校正的视频信号，以便于当前到下一个期望的灰度级转换。此后，使用例如空间滤波部分对校正后的视频信号进行空间滤波。因此，即使在普通视频信号的空间频率和潜在噪声的空间频率已经被放大之后，空间域中的高频分量也可能被减小。因此，可以降低或甚至防止不期望的噪声引起的显示质量下降，同时由于促进灰度等级转换而导致的像素响应速度增加。

摘要： A liquid crystal display apparatus includes a plurality of areas in which response speeds greatly different from each other coexist in a pixel. A first replacement process section replaces the image data of the desired target frame with a first gradation, when a gradation transition from a current frame to a desired target frame corresponds to the above gradation transition. A second replacement process section replaces the image data of the current frame with a second value. The first value is set to a value causing the pixel to respond at a relatively higher speed without the occurrence of the excessive brightness. Without avoiding the deterioration of the image, it is possible to drive a liquid crystal display apparatus including areas whose response speeds are different from each other coexist in the pixel, such as a liquid crystal display apparatus of vertically aligned mode and normally black mode.

摘要： A noise adding circuit adds noise data to video data, and a circuit rounds a less significant bit, so as to output video data of 6 bits from 8 bit input data for example. The video data of 6 bits is stored in a frame memory until a further next frame, and a previous frame grayscale correction circuit corrects video data of a previous frame as required so that the video data of the previous frame approaches video data of a further previous frame. It then outputs thus corrected video data. Further, a modulation processing section corrects video data of a current frame so as to emphasize grayscale transition from the video data of the previous frame which is outputted by the previous frame grayscale correction circuit. Thus, it is possible to realize a driving device of an image display device, which can improve a response speed of pixels and has a simple arrangement, without apparently deteriorating display quality of an image displayed in the pixels.
摘要翻译：噪声加法电路将噪声数据添加到视频数据中，并且电路使较低有效位回合，以便例如从8位输入数据输出6位的视频数据。 6位的视频数据被存储在帧存储器中，直到另外的下一帧，并且前一帧灰度校正电路根据需要校正先前帧的视频数据，使得先前帧的视频数据接近另一前一帧的视频数据帧。然后输出这样校正的视频数据。此外，调制处理部分校正当前帧的视频数据，以便强调从前一帧灰度校正电路输出的先前帧的视频数据的灰度转换。因此，可以实现图像显示装置的驱动装置，其可以提高像素的响应速度并且具有简单的布置，而不会显着地劣化在像素中显示的图像的显示质量。
