The traditional stylus lacks sensitivity and accuracy. The pen holder is made of metal material, and conductive silica gel, conductive cotton or conductive fiber are installed on the pen tip to form the pen tip. In this way, an electrified bridge is established between the finger and the screen, so that the screen can be controlled.
Capacitive stylus capacitance is a direct conductor, so the finger draws a small current from the contact point. This current flows from the electrodes at the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the position information of the touch point through the accurate calculation of these four current ratios. This stylus is easy to operate and has high sensitivity.
Moreover, when applying for a patent, Apple said, "This is a new stylus, which can complete handwriting operation in horizontal, vertical and volley states. Moreover, this stylus can write on a blank electronic module, and its content will be seamlessly transmitted to the screens of surrounding electronic devices in real time. " Many modern designers will use this kind of capacitance pen when designing things, and some even buy Apple's equipment because it has capacitance pen. It can be seen that people's demand for capacitance pen is still great, so I think that after the production of the stylus, it will greatly enhance Apple's competitive strength, so it is not nine Niu Yi hairs for Jobs.
