Abstract
The present invention discloses a touch display driving method, a driving module and a display device. The method includes: detecting whether a touch action occurs; performing display driving and touch driving in a first driving mode when no touch action is detected; performing display driving and touch driving in a second driving mode when a touch action is detected, wherein a touch driving frequency under the first driving mode is smaller than a touch driving frequency under the second driving mode. In the present invention, driving is performed in the first driving mode when no touch action is detected, and driving is performed in the second driving mode when a touch action is detected. A touch driving frequency under the first driving mode is smaller than a touch driving frequency under the second driving mode, which decreases driving frequency as a whole, thereby reducing power consumption of a driving module.
