Abstract
A source driving apparatus with power saving mechanism and a flat panel display using the same are provided. The source driving apparatus includes an output buffer stage and a power-saving circuit. The output buffer stage operates under a dual power, and has a positive and negative output channels respectively coupled to two adjacent data lines in a display panel. Moreover, the power-saving circuit is coupled between the output buffer stage and the display panel. The power-saving circuit collects charges from an equivalent load capacitor of each data line, before the output buffer stage drives the two adjacent data lines through the positive and negative output channels. The power-saving circuit charges one of a positive supply and a negative supply of the dual power in response to the collected charges, during the output buffer stage drives the two adjacent data lines through the positive and negative output channels.
