A power saving method is disclosed. The method is used for reducing the amount of power consumed by a touch display apparatus including a sensing area. The method includes: determining whether an instruction event happens in the sensing area by scanning the sensing area within a first processing period; in response to a negative determination, providing a specific sensing area within the sensing area; determining whether the instruction event happens in the specific sensing area by scanning the specific sensing area within a second processing period; and in response to a negative determination, ending the scanning of the sensing area.
