Control method and device for touch display panel, and display device
The embodiments of the present disclosure disclose a control method and device for a touch display panel, and a display device, capable of achieving a display function and a touch control function of a display panel and improving the report rate for the touch control function. An embodiment of the disclosure discloses a control method for achieving a display function and a touch control function of an in-cell capacitive touch display panel, wherein the controlling method includes: dividing a time period for the in-cell capacitive touch display panel displaying each image frame into at least two control periods each comprising a display period and a touch control period; during the display period, applying no signal or applying signals for display to touch driving electrodes of the touch display panel; and during the touch control period, applying touch driving signals to the touch driving electrodes in sequence, wherein touch sensing electrodes couple voltage signals of the touch driving signals and output the same.
