Passive stylus

This creation is about a stylus, especially a passive stylus.

In recent years, the emergence of touch screens has revolutionized the operation of electronic products. The user input commands no longer require a keyboard mouse, and the drawing directly on the touch screen can be realized. Among various touch screens, capacitive touch screens are widely used in electronic products such as mobile phones and tablet computers because of their durability. In order to improve the user's convenience, most touch panels can be used with a stylus as a click input or an input action such as writing or drawing on the touch panel. In general, the stylus has two modes of action. One is a passive stylus. The principle of a conductor is used to change the potential of the surface of the touch panel by using a weak leakage current of the human body to flow through the stylus. It is the electric field that changes the projected capacitance. The other is an active stylus, which is designed to have an electric field that can be sensed, can change the electric field of the projected capacitor, or has its own built-in capacitor and discharge loop to change the potential of the surface capacitor.

However, the above active or passive stylus has some shortcomings, for example, an active stylus, which requires an additional self-circuit and its corresponding power supply, so that the built-in space of the pen holder is complicated and the cost is high; passive touch The pen is controlled, because there is no need to add a separate self-circuit, so the inside of the hand-held part of the pen body is mostly hollow.
