1. A driving method of a touch-control display panel including a first substrate including a first touch-control display region and a second touch-control display region arranged along a first direction, wherein the first touch-control display region and the second touch-control display region are arranged adjacent to each other;

  • a plurality of touch-control driving electrodes disposed on the first substrate and extending along a second direction;

    a second substrate arranged opposite to the first substrate; and

    a plurality of touch-control detecting electrodes disposed on the second substrate, extending along the first direction, and overlapped with the plurality of touch-control driving electrodes, wherein the plurality of touch-control driving electrodes include a plurality of first touch-control driving electrodes distributed in the first touch-control display region and a plurality of second touch-control driving electrodes distributed in the second touch-control display region, a number of the first touch-control driving electrodes distributed in the first touch-control display region is equal to a number of the second touch-control driving electrodes distributed in the second touch-control display region, the plurality of first touch-control driving electrodes and the plurality of second touch-control driving electrodes include all the touch-control driving electrodes overlapped with the plurality of touch-control detecting electrodes, each first touch-control driving electrode of the plurality of first touch-control driving electrodes distributed in the first touch-control display region has a corresponding second touch-control driving electrode of the plurality of second touch-control driving electrodes distributed in the second touch-control display region, a distance from the each first touch-control driving electrode to the second touch-control display region is equal to a distance from the corresponding second touch-control driving electrode to the first touch-control display region, the each first touch-control driving electrode and the corresponding second touch-control driving electrode are scanned simultaneously, the driving method comprising;

    in a touch-control sensing period, scanning the each first touch-control driving electrode and the corresponding second touch-control driving electrode simultaneously,wherein each display period of the touch-control display panel includes at least one touch-control sensing period, anda scanning direction of the first touch-control driving electrodes in the first touch-control display region is opposite to a scanning direction of the second touch-control driving electrodes in the second touch-control display region.
