Abstract
The present invention discloses a touch panel, a driving method thereof and an electronic device. The touch panel includes an active area and an inactive area, a touch electrode and an electromagnetic functional line. The touch electrode is located in the active area, the electromagnetic functional line is electrically connected to the touch electrode to form an electromagnetic communication line, the electromagnetic communication line comprises a first terminal and a second terminal each configured to be coupled to an electrical signal to implement touch sensing function and electromagnetic communication function by controlling the electrical signal. At least the above two functions may both be advantageously implemented by the touch panel, and original lines in the touch panel are reused (multiplexed) to reduce additional lines, thereby improving the lightweight and slim features of the product and reducing the product costs.
