Abstract: The present disclosure provides a driving device for driving a display device. The driving device includes a first charge sharing switch, a second charge sharing switch and one or more third charge sharing switches. The first charge sharing switch is coupled between two adjacent odd data channels of a plurality of data channels. The second charge sharing switch is coupled between two adjacent even data channels of the plurality of data channels. Each of the one or more third charge sharing switches is coupled between two adjacent ones of the plurality of data channels. A first charge sharing is performed when the first charge sharing switch is turned on.

Abstract: A channel circuit of source driver and an operation method thereof are provided. The channel circuit includes a digital-to-analog converter (DAC), a first switch, an output buffer circuit and a pre-charge circuit. The terminals of the first switch are coupled to the first output terminal of the DAC and the first input terminal of the output buffer circuit, respectively. The pre-charge circuit is coupled to the first input terminal of the output buffer circuit. The pre-charge circuit pre-charges the first input terminal of the output buffer circuit when the first switch is turned off during a pre-charge period, and not to pre-charge the first input terminal of the output buffer circuit when the first switch is turned on during a normal operation period.

Abstract: A display driving apparatus, including an image processor, a timing controller, and a plurality of source drivers, is provided. The image processor determines whether an image frame corresponding to a frame data is a static image and outputs the frame data and a determination result. The timing controller receives the frame data from the image processor and outputs the frame data. The source drivers receive the frame data from the timing controller and drive a display panel according to the frame data. Each of the source drivers includes a memory module configured to store the frame data corresponding to the static image. When the source drivers drive the display panel according to the frame data corresponding to the static image, the image processor stops outputting the frame data to the timing controller, and the timing controller stops outputting the frame data to the source drivers.
