Abstract
First and second gradation bit groups are obtained by dividing m (4≦m<n) gradation bits from the most significant bit into two halves so as to make weights thereof half where n is a total number of gradation bits. Then, a plurality of sub-fields in the first and second gradation bit groups is arranged to be equal to each other. Subsequently, at least part of sub-fields of (n−m) non-divided gradation bits among the n gradation bits are arranged in between the first and second gradation bit groups. A time interval between the first and second gradation bit groups is thereby determined to be h/2±h/14 (msec), where h (msec) is time of one field of a video signal to be displayed.

A display method for a plasma display device using a plurality of sub-fields to display an image with gradation, comprising the steps of:
- obtaining first and second gradation bit groups by dividing m (4≦m<n) gradation bits from the most significant bit into two halves so as to make weights thereof half, where n is a total number of gradation bits;
- arranging a plurality of sub-fields in said first and second gradation bit groups so as to be equal to each other;
- and
- determining a time interval between said first and second gradation bit groups to be h/2±h/14 (msec), where h (msec) is time of one field of a video signal to be displayed, by arranging at least one sub-field of the (n−m) non-divided gradation bits among said n gradation bits in between said first and second gradation bit groups.
