AI Technical Summary
Technical Problem
When the traditional touch display panel overlaps the scanning line during the display driving period and the stop driving period, it may cause noise interference, affecting the accuracy of the touch results.
Method used
It is automatically determined between the display driving period and the non-display driving period whether the touch electrode overlaps the gate line that stops driving, and adjusts the time period of the touch scanning to avoid noise interference.
Benefits of technology
It effectively avoids touch scanning being affected by gate line noise, and improves the accuracy and quality of touch results.

Abstract
The invention provides a touch display driving method and a touch display driving circuit. The touch display driving method comprises the following steps: determining a plurality of display driving periods for driving a plurality of gate lines of the touch display panel according to a control signal; selecting a part of a plurality of non-display driving periods among the plurality of display driving periods to execute a plurality of touch scans according to the control signal; and judging whether at least one of a plurality of touch electrodes scanned in the touch display panel is overlapped with one of a plurality of gate lines which are driven to stop driving in a plurality of display driving periods on the touch display panel, and adjusting at least one of the plurality of touch scans to other parts in the plurality of non-display driving periods.
