Display device and driving method thereof

摘要

A display device of the present invention eliminates the possibility that a ratio between a display period for display signals and a display period for blanking signals differs from a preset ratio even when the video data are changed. A display device, for making images vivid at the time of visualizing animated images, sequentially supplies blanking data from a data driver circuit which sequentially supplies display signals after a lapse of a given time from starting of the supply of the display signals. The display device further includes a means which sets a ratio of display based on the blanking data per one frame period. Further, the display device includes a means which measures the number of pulses of a horizontal synchronizing signal in one frame period contained in the video data, and determines a point of time for starting display based on the blanking data in response to pulses of the horizontal synchronizing signal corresponding to the ratio based on a measured value of the number of pulses.
