The invention discloses a touch panel comprising a driving line, a grid electrode line, a reading line and a switching unit; the driving line is used for transferring a driving signal; the grid electrode line is used for sending a scanning signal; the reading line and the driving line form an induction capacitor used for responding to the driving signal according to the touch operation so as to form a first sensing signal; the switching unit is electrically coupled to the grid electrode line and the reading line, and used for selectively conduct according to the scanning signal so as to transfer the first sensing signal to the reading line.
