Abstract
A touch sensor, a touch detection device and a detection method, and a touch control apparatus are provided. The touch sensor comprises a first electrode layer, a rigid insulating layer, a second electrode layer, a compressible layer, and a third electrode layer disposed successively The compressible layer may change the distance between the second electrode layer and the third electrode layer when subjected to a touch pressure. The second electrode layer and the third electrode layer may form a capacitor structure, and the capacitance value of the capacitor structure may vary with the distance between the second electrode layer and the third electrode layer. The pressure information of a user's touch operation can be calculated from the change of the capacitance value.
