1, the working principle is different: capacitance pen transfers the finger charge to the touch screen through the internal circuit to realize the function of the pointer; The stylus communicates with the screen wirelessly or wired to achieve more accurate touch.

2. Different sensitivities: capacitance pen is usually more sensitive and can detect smaller pressure changes, thus providing a more detailed writing and painting experience; The sensitivity of the stylus is relatively low, but the nib is stronger, which is suitable for writing and drawing on hard surfaces.

3. Different functions: capacitance pen is usually only used for simple clicking, dragging and scrolling operations; The stylus can provide more functions, such as drawing and writing, and some stylus also allow users to use it as a digital signature device.
