DISPLAY DEVICE AND DRIVE METHOD THEREFOR

摘要

A polarity of a POL outputted from a polarity inversion control section (9) is always identical between a scanning period and a pause period immediately subsequent to the scanning period, and is reversed every time switching from a pause period to a scanning period is carried out. This makes it possible to both carry out pause driving and prevent image sticking on a display panel.

主权项

1. A display device comprising:
a display panel including a plurality of scanning lines, a plurality of data lines intersecting with the plurality of scanning lines, and a plurality of pixels provided separately near at respective intersections of the plurality of scanning lines and the plurality of data lines; a control signal output section outputting a control signal which alternately designates a scanning period in which a whole region of a screen of the display panel is scanned and a pause period in which an at least partial region of the screen is not scanned; a polarity designation signal output section outputting a polarity designation signal, which designates a polarity of a data signal supplied to each of the plurality of data lines, in such a manner that (i) polarity designation signals having an identical polarity are outputted in respective frames in the scanning period, (ii) the polarity of the polarity designation signals is reversed every scanning period, and (iii) a polarity designation signal outputted in each of frames in the pause period has a polarity identical to that of a polarity designation signal outputted in a scanning period immediately before the pause period; and a drive circuit supplying the data signal to the each of the plurality of data lines in the each of the frames in the scanning period, the data signal having a polarity based on a polarity of a polarity designation signal supplied to the drive circuit in the each of the frames.
