Electromagnetic Resonance (EMR) Pen Touch Module with Screen

The basic principle of electromagnetic touch screen: an electromagnetic pen emits electromagnetic signals to interact with the electromagnetic induction board behind the display screen. When the electromagnetic pen is close to the touch screen, the electromagnetic induction board behind the touch screen will sense the electromagnetic signal of the pen, causing the induction line under the electromagnetic induction board to change. Then, the antenna array in the horizontal and vertical directions receives the signal, and the X and Y coordinates of the pen are calculated through the change of magnetic flux.

Product features of electromagnetic screen
