Touch detection circuit and the method of driving the same
Abstract:
The present disclosure relates to a touch detection circuit, a driving method thereof, an embedded touch panel, and a display device. A touch detection circuit includes: a magnetic sensing circuit, a voltage input circuit, a voltage storage circuit, a piezoelectric sensing structure, a bottom gate type driving transistor, and a data processing circuit; wherein, by the cooperation of the above circuits and structures, the touch detection circuit can not only support the magnetic touch function based on the electromagnetic induction principle, but also can support the pressure sensing touch function based on the pressure sensing technology, thereby integrating the magnetic touch detection circuit with the pressure sensing device and the pressure sensing detection circuit in one touch detection circuit, and it is possible to reduce the excessive space in the display device occupied by the pressure sensing device and the pressure sensing detection circuit.
