摘要： A source driver includes a driver unit and a data analysis unit. The driver unit drives a display panel according to a video signal. The data analysis unit, which is coupled to the driver unit, analyzes gray level distribution of the video signal, and the data analysis unit enables or disables a charge sharing function of the driver unit according to an analysis result. As a result, the charge sharing function is enabled optionally during different charge sharing periods, and thus the power consumption in the source driver and the operation temperature of the source driver could be reduced as compared with the prior art.

摘要： A display controlling system utilized in a display, such as an LCD, includes a plurality of data lines and a plurality of source drivers. The source drivers receive a plurality of transfer pulse signals, each of which corresponds to one of the source drivers, and drive the corresponding data lines upon receiving the corresponding transfer pulse signal, wherein the transfer pulse signals are not all identical. The transfer pulse signal can be produced by the timing controller of the display, or the transfer pulse information required for generating the transfer pulse signals can be embedded in the source data to be delivered to the source drivers that generate the transfer pulse signals after obtaining the transfer pulse information. The transfer pulse signal lines between the timing controller and the source drivers can therefore be removed.
