Abstract: A display driving apparatus including a receiver circuit, a detection circuit and a driving circuit is provided. The receiver circuit receives the video image data at a first rate. The detection circuit is coupled to the receiver circuit. The detection circuit detects whether the video image data is a static image, and determines whether the display driving apparatus enters a power saving mode based on a detecting result. The driving circuit is coupled to the receiver circuit. The driving circuit drives the display panel. In the power saving mode, the receiver circuit continuously receives the video image data at the first rate, and periodically masks a part of the video image data according to the detecting result and outputs an unmasked part of the video image data to the driving circuit. Furthermore, a display driving method adapted for the foregoing display driving apparatus is also provided.

Abstract: A display driving apparatus including a signal transmission interface, a timing control circuit and an image detection circuit is provided. The signal transmission interface is configured to receive video image data and output the video image data. The timing control circuit is configured to receive the video image data and drive a display panel based on the video image data. The image detection circuit determines whether the video image data is a static image and determines whether the display driving apparatus operates in a power-saving mode based on the determination result. Under the power-saving mode, the signal transmission interface masks a part of the video image data, so as not to output the masked video image data to the timing control circuit. Furthermore, a display driving method adapted for the foregoing display driving apparatus is also provided.
