Display device and driving method thereof

A driving method for a display device in which to a display device which comprises a pixel array in which a plurality of pixel rows each of which includes a plurality of pixels arranged in parallel along the first direction are arranged in parallel along the second direction which intersects the first direction, a scanning driver circuit which selects the plurality of respective pixel rows in response to a scanning signal, a data driver circuit which supplies a display signal to the respective pixels included in at least one row selected in response to the scanning signal out of the plurality of pixel rows, and a display control circuit which controls a display operation of the pixel array, lines of image data are inputted one after another for every horizontal scanning period, wherein

• the data driver circuit alternately repeats (i) a first step for generating a display signal corresponding to each one of the lines of the image data one after another and outputting the display signal to the pixel array N-times (N being a natural number equal to or greater than 2) and (ii) a second step for generating a display signal which makes the luminance of the pixels lower than the luminance of the pixel in the first step and outputting the display signal to the pixel array M-times (M being a natural number smaller than N),
• the scanning driver circuit, in response to inputting of a scanning clock, alternately repeats (i) a first selection step for selecting the plurality of pixel rows for every Y rows (Y being a natural number smaller than the N/M) sequentially from one end to another end of the pixel array along the second direction in the first step and (ii) a second selection step for selecting the plurality of pixel rows other than the pixel rows (Y×N) selected in the first selection step for every Z rows (Z being a natural number not smaller than N/M) sequentially from one end to another end of the pixel array along the second direction in the second step, and
• the display signal outputted in the first step of the image data is delayed from a memory in which the display signal is stored in the vicinity of a boundary between one frame period and a frame period next to the one frame period within a time-sequential interval between the display signal which is outputted in the second step of the last image data in a certain frame period and the display signal which is outputted from the second step of the first image data in the next frame period.
