Abstract: A control method for a touch display device including a display panel is provided. The display panel includes multiple first gate lines and multiple second gate lines respectively corresponding to a first field and a second field of a frame, and multiple sensing electrodes for touch sensing. Within one single frame period, the control method includes: scanning the first gate lines to update the first field; controlling the sensing electrodes to perform touch sensing and providing a first touch report; scanning the second gates lines to update the second field; and controlling the sensing electrodes to perform touch sensing and providing a second touch report. At least one of the first gates lines is located between two of the second gate lines, and at least one of the second gate lines is located between two of the first gate lines.
