CTP large size active pen scheme

CTP large size active pen scheme

The active capacitance pen can achieve the effect similar to the actual thickness of the pen tip, so that the pen can sense the change of user's writing intensity, so that the handwriting can be more varied to change the handwriting's thickness and achieve excellent user experience.
Principle
The active capacitance pen can be made up of power, micro controller, supercharger, pressure sensor and pen head. The active capacitance pen itself is equivalent to the signal emission source. The sensor of the touch screen receives the signal from the capacitance pen, and calculates the coordinates of X and Y.
Application
Electronic devices such as mobile phones, computers, etc. Note recording, painting creation, document standard, painting and so on.
