Abstract:
1. A display comprising: a display panel provided with scanning lines, signal lines located to intersect the scanning lines, and sub-pixels connected to the signal lines; a source driver, whose output terminals are each connected to an associated one of the signal lines, for driving the sub-pixels; and a controller for supplying a control signal to the source driver, wherein given that n is an integer of two or more, the polarity of an output voltage supplied from each output terminal is switched relative to a common voltage in every n horizontal scanning periods, and the timing of switching of the polarity of the output voltage is shifted by one horizontal scanning period for each frame, the source driver has a polarity shift circuit to which a polarity switching signal for controlling the switching of the polarity of the output voltage is inputted, and which outputs the polarity switching signal by shifting the signal by one horizontal scanning period for each frame, and the source driver has electrical charge recovering means which controls such that at least the two output terminals are short-circuited for a certain period of time in n horizontal scanning periods in reaction to the output of the polarity shift circuit.
