TOUCH DETECTION DEVICE Russian patent published in 2017 - IPC H03K17/955 H03K17/96 H03K17/975 

FIELD: physics.

SUBSTANCE: device comprises the first electrode and the second electrode facing each other, an excitation detecting circuit of the electrostatic capacitance type, the first switching circuit that performs switching between the connection and the disconnection between the first electrode and the ground, and the second switching circuit that performs switching between the connection and the disconnection between the first electrode and the second electrode. The excitation detecting circuit performs switching between the first state and the second state, and detects the change in the electrostatic capacitance of the first state, and the change in the electrostatic capacitance of the second state.

EFFECT: preventing the erroneous touch detection.
