Abstract: Touch-control screen, driving method thereof, and touch-control apparatus are provided. The touch-control screen includes a touch-control area and a driving unit. The touch-control area includes a main touch-control area and an auxiliary touch-control area smaller than the main touch-control area. The touch-control area further includes a plurality of touch-control electrodes, having a plurality of first touch-control electrodes in the main touch-control area and a plurality of second touch-control electrodes in the auxiliary touch-control area. In a touch-control stage, the driving unit is configured to transmit electrical signals respectively to the plurality of first touch-control electrodes in the main touch-control area and to the plurality of second touch-control electrodes in the auxiliary touch-control area. A unit power consumption of the plurality of second touch-control electrodes in the auxiliary touch-control area is smaller than a unit power consumption of the plurality of first touch-control electrodes in the main touch-control area.
