Claim Text:
1. A method of driving a display device which includes a display panel having pixels and which is configured such that (i) a scanning signal and an image signal are supplied to the display panel in a scanning frame and (ii) no scanning signal and no image signal are supplied to the display panel in a pause frame, the method comprising: supplying an image signal, having a polarity opposite to that of voltages applied to the respective pixels in a current frame, to the display panel in a next frame, in a case where a polarity balance value, indicative of a polarity balance of the pixels in the current frame, is equal to a predetermined reference value, wherein: in a case where a first image signal corresponding to the current frame does not match a second image signal corresponding to a previous frame, the first image signal is supplied to the display panel in a first driving period made up of at least one successive frame, i.e., the next frame only or the next frame and succeeding frame(s); in a case where (i) the first image signal matches the second image signal and (ii) the polarity balance value is equal to the predetermined reference value, the second image signal is supplied to the display panel in a second driving period made up of the at least one successive frame, i.e., the next frame only or the next frame and the succeeding frame(s), the second image signal being supplied to the display panel in the next frame in the second driving period, which second image signal has a polarity opposite to that of the voltages applied to the respective pixels in the current frame; and in a frame which is not included in any of the first driving period and the second driving period, no image signal is supplied to the display panel.
