Abstract
A touch detection device includes a touch panel, a piezoelectric sensor mounted on the touch panel for detecting a tap event applied to the touch panel, and a control circuit board in electrical communication with the piezoelectric sensor. The control circuit board includes a signal processing circuit for processing a detection signal output from the piezoelectric sensor, and a controller for determining whether the tap event is a correct human finger tap event based on the processed detection signal.
