Abstract
A timing controller carries out display refresh on a display panel in a first frame which comes one frame after a second frame in which (i) an image signal supplied from an interface matches an image signal stored in a frame memory and (ii) a polarity balance value is equal to a reference value. In this case, the image signal, having a polarity opposite to that of pixel applied voltages in the second frame, is supplied to the display panel in the first frame. This makes it possible to prevent a deterioration in the display panel while reducing electric power consumption.
