Power Saving Method and Touch Display Apparatus
First Claim
1. A power saving method for reducing the amount of power consumed by a touch display apparatus, wherein the touch display apparatus comprises a sensing area, the power saving method comprising the following steps:
- determining whether an instruction event happens in the sensing area by scanning the sensing area within a first processing period;
when it is determined that no instruction event happens in the sensing area within the first processing period, 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
when it is determined that no instruction event happens in the sensing area within the second processing period, ending the scanning of the sensing area.

Abstract
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.

11. A touch display apparatus comprising:
-
a touch screen comprising a sensing area; a marking module connected to the touch screen, used for marking a specific sensing area, wherein the specific sensing area falls within the sensing area; and a scanning module connected to the touch screen, used for scanning the sensing area within a first processing period so as to determine whether an instruction event happens in the sensing area, and when it is determined that no instruction event happens within the first processing period, scanning the specific sensing area within a second processing period so as to determine whether the instruction event happens in the specific sensing area, and when it is determined that no instruction event happens in the specific sensing area within the second processing period, ending the scanning of the sensing area. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
