摘要： 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：首先调制或改变数据，例如视频信号数据，用于下一个所需帧，以便于从当前帧到下一个所需帧的转换。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良的噪声引起的显示质量下降，同时由于灰度等级转换的促进而引起的像素响应速度增加。

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.

The first phase plate has biaxial optical anisotropy and has functions of compensating part of thickness-direction retardation of the liquid crystal layer in the black display state and suppressing light leakage caused by deviation of the transmission axes of the first and second polarizing plates from the mutual orthogonal relationship in a tilted viewing angle direction. The second phase plate has negative uniaxial optical anisotropy and has a function of compensating the thickness-direction retardation of the liquid crystal layer in the black display state in cooperation with the first phase plate.

摘要： RGB colors are displayed with the same gradation by applying different voltages to display elements in pixels (7). This is in turn done by, for example, either producing a different reference voltage for each RGB color in a reference voltage generating circuit (8) or making reference to a LUT stored in a memory section (15). Hence, color discrepancies in a display element can be effectively limited.
摘要翻译：通过对像素（7）中的显示元件施加不同的电压，RGB颜色以相同的灰度显示。这又通过例如为参考电压产生电路（8）中的每个RGB颜色产生不同的参考电压或者参考存储在存储器部分（15）中的LUT来完成。因此，可以有效地限制显示元件中的颜色差异。

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： 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： A color display device includes a shutter type color display and signal processing means. The signal processing means has color conversion processing means for increasing a gradation level of a color signal having the highest gradation level while decreasing a gradation level of a color signal having the lowest gradation level when the gradation levels of the plural color signals are not equal one another, and for outputting a color signal has been processed to the shutter type color display. Further, a color display having a reflective member or a diffuse transmission member provided on a display screen or in the vicinity of the display screen, a color plasma display, or a color field emission display can also be used instead of the shutter type color display. Thus, even when chroma of the color display is low, a display in high chroma can be ensured.
