The invention provides a pressure touch control apparatus, a pressure touch control feedback method and a touch control display apparatus, which relates to the technical field of touch control. The pressure touch control apparatus is provided with a first area and a second area which are different in thickness, and also comprises a pressure sensor, a sensing electrode, a circuit board, an auxiliary electrode and a spacer layer, wherein the pressure sensor covers the first area and the second area; the sensing electrode is arranged in the first area; the circuit board is arranged in the secondarea; the auxiliary electrode is arranged on one side, away from the pressure sensor, of the circuit board; the spacer layer is arranged between the pressure sensor and the sensing electrode as well as between the pressure sensor and the circuit board; and the sum of the thickness of the circuit board and the auxiliary electrode is equal to the thickness of the sensing electrode. By adopting the pressure touch control apparatus, the complete full-screen pressure touch control effect can be realized.
Description
Technical field [0001] The present disclosure relates to the field of touch technology, and in particular to a pressure touch device, a feedback method of pressure touch, and a touch display device. Background technique [0002] Force Touch technology is a touch technology that can not only recognize the user's touch operation, but also realize force perception. Simply put, this technology can sense whether the user is performing a "tap" operation or a "press" operation, so that it can feedback different actions and functions on different interfaces. [0003] Currently, there are many ways to implement Force Touch, such as resistive pressure touch and capacitive pressure touch. Resistive pressure touch can realize the sensing of touch force through pressure sensing, but it has relatively high pressure requirements and poor sensitivity. Capacitive pressure touch can realize the perception of touch force by changing the capacitance value between the plates. When a finger touches th...
