Display device, and driving method and electronic apparatus of the display device

A driving method of a display device for expressing gradation by dividing one frame into a plurality of sunframes, 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 k (here k is an integral number satisfying k=3) 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 (k+1) or more, and arranging each about half of which in each of the k 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 k, and arranging each one of which in each of the k subframe groups of the one frame;
• and
• dividing each of 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 into in (k−1) or less or not dividing, and arranging in at least one of the k 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 among the k subframe groups of the one frame;
• and wherein as for a part or all of the plurality of subframes corresponding to bits belonging to the first bit group and the plurality of subframes corresponding to bits belonging to the second bit group, an overlapped time gray scale method is used in each of the k subframe groups of the one frame.

• wherein luminance is changed linearly in a region of a low gray scale level and in the other region of the other gray scale levels, luminance is changed nonlinearly.
