1. A touch control structure, comprising:

  • a first conductive layer;

    a second conductive layer comprising a plurality of electrodes which are independent from each other;

    a plurality of insulative supporting points arranged on the second conductive layer and under the first conductive layer; and

    a detection module connected to the plurality of electrodes, and configured to detect an electrode in the second conductive layer contacted with the first conductive layer when the first conductive layer is pressed, and to determine a level of pressure pressed on the first conductive layer based on the detected electrode,wherein the detection module is further configured to count an amount of the electrode in the second conductive layer contacted with the first conductive layer, to compute a first difference between a last counted amount and a first counted amount in response to the counted amount becoming steady, and to determine the level of pressure based on the first difference, the first counted amount being obtained at the beginning of the pressing, the last counted amount being obtained when the counted amount becomes steady, orwherein the detection module is further configured to measure a total current flowing through the electrode in the second conductive layer contacted with the first conductive layer, to compute a second difference between a last total current and a first total current in response to the total current becoming steady, and to determine the level of pressure based on the second difference, the first total current being measured at the beginning of the pressing, the last total current being measured when the total current becomes steady.
