Abstract: A liquid crystal display device carries out tone display with pixels by applying a tone voltage according to tone data to each pixel in each frame, and includes: an LUT memory, which receives tone data of a display frame and tone data of an immediately preceding frame, for converting and outputting the tone data of the display frame; a source driver for applying the tone voltage to the pixels based on the converted tone data outputted from the LUT memory; and a liquid crystal cell, which makes up the pixels, for realizing tone display by the applied tone voltage, wherein the LUT memory stores beforehand output tone data which is specified by the tone data of the display frame and the tone data of the immediately preceding frame. This reduces a voltage change of pixel electrodes which is associated with a tone change to suppress unmatched tone display, thereby improving image quality of moving images.

Abstract: Based on each of video data repeatedly supplied to a pixel, a signal processing section generates video data (Dd) for an image display period to be supplied to the pixel and video data (Db) for a blanking period to be supplied to the pixel, and outputs the video data (Dd) and (Db) in a predetermined order. Further, when a gradation transition from a gradation indicated by previous video data (D(i,j,k?2)) supplied to the pixel to a gradation indicated by current video data (D(i,j,k)) supplied to the pixel indicates an increase in luminance, a generating circuit for a blanking period of the signal processing section outputs video data indicative of a gradation which is increased compared with a gradation indicated by gradation data for a blanking period in a steady state, the video data thus outputted being regarded as video data (Db(i,j,k?1)) for a blanking period. This allows for providing a display device capable of displaying moving images with high quality.

Abstract: 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.

Abstract: There is provided a motion-adaptive grayscale level converter section between a video signal source and a pixel array. The pixel array includes a liquid crystal cell of normally black and vertically aligned mode. The motion-adaptive grayscale level converter section determines based on information from a decoder section whether the pixels of an image represented by a video signal is in a moving image area. If a pixel is in a moving image area, the motion-adaptive grayscale level converter section changes the grayscale level data representing the grayscale level of the pixel so that there is no darker grayscale level than a predetermined first grayscale level. The resultant data is output as a video signal. Accordingly, we can provide a liquid crystal display capable of easing image quality degradation due to insufficient response when displaying a moving image while maintaining the contrast ratio achieved for a still image display.

The emission of each display element is changed per one frame time between a normal ON state and a dim state. The cold cathode tube has two or more OFF periods within one frame time, and, luminance of the cold cathode tube is changed per one frame period.
