摘要:
A touch drive method, a touch display device, and an electronic equipment are provided. The touch display device includes a display structure and a touch structure stacked with the display structure, a touch scan frequency of the touch structure is different from a display scan frequency of the display structure, and the touch drive method includes: applying a touch scan signal to the touch structure during a process in which the display structure performs progressive scan in respond to a row synchronization signal; a display noise signal is generated during at least one level switching process of the row synchronization signal; and each period of the touch scan signal has a signal rising edge and a signal falling edge, and the signal rising edge and the signal falling edge of each period of the touch scan signal are respectively located outside a noise duration of the display noise signal.
