摘要： A display has a circuit for comparing video data for a first or current frame with video data for a second or desired frame. A processing section makes an instruction for a process to take place if certain conditions are met. In response to the instruction for a process, a signal generation circuit outputs a signal which reduces a degree of modulation or variation by which tone transition is facilitated relatively to a case where pixels are driven on the basis of data output from an ordinary processing section. Thus, by modulating or varying a drive signal to a degree suitable for a case where tone transition is sufficient, a display capable of improving display quality even in a situation where the display is not capable of being driven suitably, can be realized using circuitry of a relatively small scale.

摘要： In a method for driving a display, a display, and a program therefor, a memory stores uncorrected video data for a desired frame and for a current frame until a next frame. Meanwhile, a correction section reads uncorrected video data for the previous frame and the current frame from the memory and corrects the video data for the current frame. Further, a processing section corrects video data for the next frame based on the corrected video data for current frame so as to facilitate a grayscale level transition from the current frame to the next frame.

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： 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.
