Field-sequential color display unit and display method
First Claim
1. A field-sequential color display method comprising:
- time-sequentially displaying of luminous information of an input image information with every display color; and
changing the display color in synchronism with the displaying of the luminous information in order to display the input image information, wherein one frame period in which one color image is displayed comprises at least four sub-field periods in which information of each color is displayed, and a picture signal displayed in at least one sub-field period is a non-three-primary color picture signal comprising a color determined on the basis of the color picture signals of the input image information in one frame period, the color not being fixed to one color.

Abstract
There is provided a field-sequential color displaying method capable of reducing color breakup with respect to an optional image without greatly increasing a sub-field frequency. The field-sequential color display method includes; time-sequentially displaying of luminous information of an input image information with every display color and changing the display color in synchronism with the displaying of the luminous information in order to display the input image information, wherein one frame period in which one color image is displayed includes at least four sub-field periods in which information of each color is displayed, and a picture signal displayed in at least one sub-field period is a non-three-primary color picture signal which is generated from at least two primary color signals of input picture signals including three-primary color signals.

11. A field-sequential color display unit comprising:
-
a sub-field determiner determining variably a non-three-primary color from three-primary color signals on the basis of an input picture signal including the three-primary color signals;
a non-three-primary color picture signal generator generating a non-three-primary color picture signal including the non-three-primary color which is determined by the sub-field determiner;
a monochrome image display sequentially displaying an input picture signal as a monochrome image;
a color display capable of changing a display color every sub-field period at least four of which constitutes one frame period, in which one image is displayed, in synchronism with the monochrome image displaying; and
a display color controller controlling the color display so as to display the non-three-primary color picture signal in at least one of the sub-field periods. - View Dependent Claims (12, 13, 14, 15, 16, 18, 19)
