  • Touch sensing device and electronic device having hybrid sensing structure
    Patent number: 11144151
    Abstract: A touch sensing device includes: first and second touch sensor devices disposed on internal surfaces of first and second touch sensing members, respectively; a force sensor device spaced apart from an internal surface of a force sensing member; an oscillation circuit configured to generate a first oscillation signal, based on a change in capacitance in response to the first touch sensing member being touched; generate a second oscillation signal, based on a change in capacitance in response to the second touch sensing member being touched; and generate a third oscillation signal, based on a change in inductance depending on a change in spacing between the force sensing member and the force sensor device; and a touch detection circuit configured to adjust a threshold for force sensing through the force sensor device depending on positions of the first and second touch sensing members, based on the first and second oscillation signals.
