Small universal disk pen

Touch Pen for iPhone

What is the principle of a stylus pen?

The active stylus pen means that there is a circuit in the pen, and the pen transmits a signal to the touch screen matrix to detect the coordinates of the pen. The pen tip is medium, needs to be charged, and can be designed with multiple functions.
The passive stylus pen can be used as a finger and does not emit signals by itself, but contact with the touch screen can change the capacitance of the touch screen matrix. This kind of pen does not emit a signal, so either the pen tip is very large (to have sufficient sensitivity, like many ipad pens); or the mobile phone is the main feature, and the touch screen resolution is specially designed for passive stylus pens (like Sony's xperia z ultra, You can draw any sharp conductor).
