  • a means for dividing one frame period into a plurality of sub-frame periods;

    means for selecting a light emitting state or a non-light emitting state in each of the plurality of sub-frame periods in accordance with a n-bit digital signal (where n is a natural number) input to a pixel;

    means for selecting a first display mode or a second display mode;

    means for inputting the n-bit digital signal to the pixel as a first digital image signal during the one frame period in the first display mode;

    means for inputting a first bit digital signal to a m-th bit digital signal (where m is a natural number less than n) of the n-bit digital signal to the pixel as a second digital image signal during the one frame period in the second display mode; and

    means for changing a length of each of the m sub-frame periods in the second display mode which are respectively corresponding to the second digital image signal, to q times a length of each of the m sub-frame periods in the first display mode which are respectively corresponding to the first bit digital signal to the m-bit digital signal of the first digital image signal (where q is a number greater than
