capacitive touch screen stylus 5 points
A capacitive screen on a mobile phone usually has a glass face and doesn't rely on pressure. This makes it more responsive than a resistive screen when it comes to gestures such as swiping and pinching. Capacitive touchscreens can only be touched with a finger, and will not respond to touches with a gloves or other objects.

Interface of CTP
The surface capacitive is a thin layer of electrodes which lied under a glass surface covered with a protective layer. Four electrodes on the corner of the panel are providing electric voltage to the film. When a conductive material is near the electrode film, there's a change of the electrostatic capacity. Measuring these changes, the controller figures out where a touch has occurred.
