  • Patent number: 10216323
    Abstract: A touch substrate, a display device and a driving method thereof, touch pressure driving electrodes and touch pressure sensing electrodes provided between the layer where the touch detecting electrodes is located and the substrate carrier are added within the touch substrate, and the touch pressure sensing electrodes and the touch pressure driving electrodes constitute a mutual-capacitance structure. When the touch substrate is pressed, the distance between the touch substrate and the underlying metal layer becomes small, causing that capacitance value of the mutual-capacitance structure becomes small. During the time period for detecting pressure, through applying the touch driving signal to the touch pressure driving electrodes to detect the change of signal amount of the touch pressure sensing electrodes caused by the pressure on the touch position, the change of the capacitance value of the mutual-capacitance structure can be determined to achieve the function of pressure sensing.
