摘要： There is provided a display device capable of displaying an image that barely changes with low power consumption on the basis of video data included in a transmitted command, and there is also provided a method for driving the same. A display timing controller (31) determines every frame period whether or not an externally transmitted command includes updated video data. As a result, when it is determined that no updated video data is included, screen refreshing is paused by not reading video data stored in frame memory (36). Moreover, when it is determined that updated video data is included, the screen refreshing is performed by reading video data stored in the frame memory (36).
