Abstract: Low frequency drive is performed that provides, after a charging period for refreshing a screen, a pause period for pausing the refresh. The length of the charging period is, for example, one frame and the length of the pause period is, for example, 59 frames. When new image data IMD is transmitted from a host to an LCD driver IC during the pause period, an interrupt process where the pause period is allowed to transition to the charging period is performed immediately thereafter. By performing the interrupt process, without waiting for the pause period with the predetermined length to end, the next charging period where refresh based on the new image data IMD is to be performed starts.

Abstract: An object of the invention is to provide a display device and a driving method thereof, in which uniformity of a video image displayed after charge sharing does not deteriorate. In a first horizontal period, a positive voltage and a negative voltage according to a video signal are alternately applied to source signal lines, and then, reset voltages of +5V and ?5V are respectively applied to source signal lines. As a result, the voltages of the source signal lines become +5V or ?5V. In this state, when the source signal lines to which +5V and ?5V are applied are short-circuited in the beginning of a second horizontal period, charge sharing is performed between the source signal lines, and the voltages of these source signal lines become 0V. Subsequently, when the voltage according to the video signal is applied, the liquid crystal display device can display a color video image having reduced display unevenness and high uniformity.
