Display device and drive method therefor

摘要

A polarity inversion control section (9) supplies a polarity designation signal, which designates a polarity of a data signal, to a data line drive circuit (5) while reversing a polarity of the polarity designation signal every frame. Even in a case where a pause driving control section (8) receives a designation signal that designates a sum of the number of frames constituting a scanning period and the number of frames constituting a pause period to be an even number, the pause driving control section (8) maintains the sum of the number of frames constituting a scanning period and the number of frames constituting a pause period to be an odd number.

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 frame count calculation section calculating each of a number of frames constituting a scanning period in which a whole region of a screen of the display panel is scanned and the number of frames constituting a pause period in which an at least partial region of the screen is not scanned; a control signal output section outputting a control signal which alternately designates the scanning period and the pause period; 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, while reversing a polarity of the polarity designation signal every frame; and a drive circuit supplying the data signal to 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 the polarity of the polarity designation signal supplied to the drive circuit in the each of the frames, the frame count calculation section recalculating, when a sum of the number of the frames constituting the scanning period and the number of the frames constituting the pause period is an even number, each of the number of the frames constituting the scanning period and the number of the frames constituting the pause period until the sum becomes an odd number.
