Classification: CPC G  H | IPC G

Claim 16:
17. The touch sensing device of claim 12, further comprising:
a substrate configured to be disposed inside the electronic device; and
a circuit unit mounted on the substrate and connected to the first touch sensing unit, the first force sensing unit, the second touch sensing unit, and the second force sensing unit,
wherein the circuit unit comprises:
a first oscillation circuit connected to the first touch sensing unit and the first force sensing unit and configured to generate a first oscillation signal having a resonant frequency that changes in response to the first touch member being touched and changes in response to the first force member being pressed,
a second oscillation circuit connected to the second touch sensing unit and the second force sensing unit and configured to generate a second oscillation signal having a resonant frequency that changes in response to the second touch member being touched and changes in response to the second force member being pressed, and
a touch detection circuit configured to detect whether the first touch member is being touched and whether the first force member is being pressed based on the resonant frequency of the first oscillation signal, and detect whether the second touch member is being touched and whether the second force member is being pressed based on the resonant frequency of the second oscillation signal.
