<P>PROBLEM TO BE SOLVED: To reduce a false contour which is generated when displaying in a time grayscale system. <P>SOLUTION: A pixel is divided into m (m is an integer of m≥2) sub-pixels, and an area ratio of an s-th (s is an integer of 1 to m) sub-pixel is to be 2<SP>s-1</SP>. Also, k (k is an integer of k≥2) sub-frame groups including a plurality of sub-frames are provided in one frame, along with dividing one frame into n (n is an integer of n≥2) sub-frames, so that a ratio of a lighting period length of a t-th (t is an integer of 1 to n) sub-frame is 2<SP>(t-1)m</SP>. Further, each of the n sub-frames is divided into k sub-frames each having a lighting period length that is about 1/k of each of the n sub-frames, and one of these is provided in each of the k sub-frame groups. At this time, in the k sub-frame groups, the sub-frames are arranged so that an appearance order of the sub-frame may become the same. <P>COPYRIGHT: (C)2007,JPO&INPIT |
