A flat panel display screen having electromagnetic induction touch control function, including a flat panel display screen main unit and a touch control induction layer, the output of the touch control induction layer being connected to a recognition circuit, and touch control operation of the display screen being operated by an electromagnetic input pen. The touch control induction layer is placed behind the flat panel display screen, wherein the touch control induction layer is constituted by an electromagnetic induction generation layer and a bottom support bracket layer, wherein a base layer of the electromagnetic induction generation layer is an insulated flexible membrane, the surface of the membrane is printed with an electromagnetic induction antenna array, constituting a flexible membrane type electromagnetic induction generation layer, the output of that layer is connected to and controls the recognition circuit, and the input pen has an electromagnetic wave generation device. An insulating shielding isolating layer is provided behind the touch control induction layer, and a recognition circuit layer is provided behind the insulating shielding isolating layer. The present invention has a simple manufacturing technique, low cost, high precision, and long operating life.
