  • Patent number: 12105919
    Abstract: A three-dimensional touch sensor and a display device are provided. The three-dimensional touch sensor determines a position of a touch force by a first capacitance formed by the pressure receiving electrodes and the transmitting electrodes, and determines a magnitude of the touch force by a second capacitance formed between the pressure receiving electrode and the pressure sensing electrode. Therefore, not only the position of the touch force but also the magnitude of the touch force can be determined. Synchronous sensing of the position and the magnitude of the touch force is achieved, which is beneficial to human-computer interaction.
