The working Principle of Touch Panel.
A key, that is, a Sensor Pad and the ground can also form an inductive capacitance. When a human finger is close to the touch key, the inductive capacitance formed by the human finger and the ground is connected in parallel with the inductive capacitance formed by the Sensor Pad and the ground, which will increase the total inductive capacitance value. After the capacitive touch key IC detects that the inductive capacitance value of a key changes, it will output a confirmation signal that a key is pressed.
