Abstract
A source driver pre-charging apparatus including a data detection module, a determining module, and a pre-charging module is disclosed. The data detection module captures a first most significant bit having N bits in a current data and a second most significant bit having N bits in a former data and compares them to generate a compared result. N is a positive integer larger than or equal to 2. The determining module judges whether any data is transited from a first grey-level region to a second grey-level region between the former data and the current data and at least one other grey-level region is existed between the first grey-level region and the second grey-level region. If the judgment result of the determining module is yes, the pre-charging module performs a pre-charging action on an output voltage of a source driver.
