Abstract: A touch sampling control module, a touch sampling control module method, and a display touch device. The touch sampling control module includes a touch sampling flag generation circuitry and a sampling time control circuitry. The touch sampling flag generation circuitry is configured to generate a touch sampling flag in accordance with a fluctuation time point of a data voltage applied to a touch display panel. The sampling time control circuitry is configured to control a touch sampling time in accordance with the touch sampling flag, so that the touch sampling time is different from the fluctuation time point of the data voltage. The data voltage fluctuates when an absolute value of a voltage change of the data voltage is larger than a voltage change threshold.
