1. A touch sampling control module for a display touch device, wherein the display touch device comprises a touch display panel, and the touch sampling control module comprises a touch sampling flag generation circuitry and a sampling time control circuitry,
wherein 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 the 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, and the data voltage fluctuates when an absolute value of a voltage change of the data voltage is larger than a voltage change threshold.
