Touch drive method, touch display device, and electronic equipment

A touch display device, comprising:

• a display structure, a touch structure, and a control unit,
• wherein the display structure and the touch structure are stacked, and a touch scan frequency of the touch structure is different from a display scan frequency of the display structure,
• the control unit is configured to provide a row synchronization signal to the display structure, and apply a touch scan signal to the touch structure during a process in which the display structure performs progressive scan in respond to the row synchronization signal,
• wherein 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, wherein the control unit is further configured to:
• generate a display mask signal based on the display noise signal,
• wherein the display mask signal comprises a first level and a second level,
• in a time domain, the noise duration of the display noise signal overlaps with a duration of the first level of the display mask signal, and a non-noise duration of the display noise signal overlaps with a duration of the second level of the display mask signal.
