Abstract:
Provided is a display device capable of displaying a smooth video even when pause drive is performed.In a liquid crystal display device with an animation function, 12-Hz pause drive is performed with vertical display periods, each having a duration of five frames. In a video display period, an animation video changes every duration of a secondary video display period, i.e., every one frame, in the order: images A to X, then A and B. Once the video display period starts, 12-Hz pause drive switches to 60-Hz normal drive. In this case, for the animation video that changes every duration of the secondary video display period, i.e., every one frame, in the order: images A to X, then A and B, refresh is performed every duration of the vertical display period, i.e., every one frame. In this manner, the duration of the vertical display period is set to be the same as the duration of the secondary video display period, whereby refresh is performed individually for images A to X, A, and B included in the animation video.
