  • Patent number: 10379653
    Abstract: A touch substrate includes a first transparent electrode layer, a transparent flexible dielectric layer and a second transparent electrode layer. The first transparent electrode layer comprises first touch detection electrodes arranged in an array and insulated from each other. During the touch detection period, a first touch detection signal is loaded simultaneously to the first and second transparent electrode layer, and the touch position can be determined by detecting a change in the capacitance value of each of the first touch detection electrodes. During the pressure detection period, a second touch detection signal may be loaded to one of the first transparent electrode layer and the second transparent electrode layer, and the pressure in the z direction perpendicular to the surface of the touch screen can be determined by detecting a change in the capacitance value between each of the first touch detection electrodes and the second transparent electrode layer.
