A touch panel with electromagnetic induction function comprising a light-emitting diode backlight layer, an electromagnetic antenna, a display panel layer, a touch panel layer and a protective layer. The light emitting diode backlight layer has a plurality of light emitting diode units. The electromagnetic antenna is disposed on the backlight layer for emitting an alternating electromagnetic field and receiving a resonance signal. The display panel layer is disposed on the backlight layer. The touch panel layer is disposed on the display panel layer for capacitive touch. The protective layer is disposed on the touch panel layer to protect the touch panel layer. An electromagnetic pen for electromagnetic touch is configured to receive the alternating electromagnetic field and then emit the resonance signal.
