The active capacitance pen is internally provided with a sensor, can actively detect signals in the capacitance screen and give corresponding driving signals, and the pen point can be very thin, so that a better writing effect can be realized. The existing active capacitive pen scheme, such as ApplePencil, needs to be paired with equipment for use, and a touch pen can only be used on matched touch screen equipment and cannot be adapted to other touch screen equipment.

A capacitive stylus with universality and cost performance is needed, cost can be reduced, and writing efficiency and experience can be improved.
