DISPLAY DRIVING APPARATUS AND DISPLAY DRIVING METHOD THEREOF

摘要

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.

主权项

1. A display driving apparatus, adapted to drive a display panel according to video image data, the display driving apparatus comprising:
a signal transmission interface, receiving the video image data and outputting the video image data; a timing control circuit, coupled to the signal transmission interface, receiving the video image data, and driving the display panel based on the video image data; and an image detection circuit, coupled to the signal transmission interface, receiving the video image data, determining whether the video image data is a static image, and determining whether the display driving apparatus enters a power saving mode based on a determination result, wherein in the power saving mode, the signal transmission interface masks a part of the video image data according to the determination result, so as not to output the masked video image data to the timing control circuit.
