Abstract:
1. A driving method of a display device for expressing gradation by dividing one frame into a plurality of subframes, in the case where gradation is expressed with an n bit (here n is an integral number), comprising: classifying bits each of which is shown by a binary of gray scales into three kinds of bit groups, that is, a first bit group, a second bit group, and a third bit group; dividing the one frame into two subframe groups; dividing each of a (here, a is an integral number satisfying 0<a<n) subframes corresponding to bits belonging to the first bit group into four and arranging each two of which in each of the two subframe groups of the one frame; dividing each of b (here, b is an integral number satisfying 0<b<n) subframes corresponding to bits belonging to the second bit group into two, and arranging each one of which in each of the two subframe groups of the one frame; and arranging c (here, c is an integral number satisfying 0<c<n and a+b+c=n) subframes corresponding to bits belonging to the third bit group in at least one of the two subframe groups of the one frame, wherein an appearance order of a plurality of subframes corresponding to bits belonging to the first bit group and a plurality of subframes corresponding to bits belonging to the second bit group is approximately the same between the two subframe groups of the one frame, and wherein a selection method of subframes is changed depending on whether the frame number is an odd number or an even number.
