Abstract: A driving method of a touch display device is provided. In a first display period of a first frame time, m gate signals are sequentially provided to first to mth gate lines, respectively, wherein m is a positive integer. In a first touch control period of the first frame time immediately following the first display period, a touch driving signal is provided to a touch sensor. In another first display period of a second frame time immediately following the first frame time, p gate signals are sequentially provided to the first to gate lines, pth respectively, where p is a positive integer and is different from m. In another first touch period of the second frame time immediately following the another first display period, the touch driving signal is provided to the touch sensor.
