    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.

    摘要: 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.
