In the 21st century, the most indistinguishable technology product is a mobile phone. Technological developments and advances have brought new and progressive spaces to mobile phones, and they have become more and more comfortable in design, and the emergence of touch screens has made smartphones quickly market, in which the screens are replaced by many advantages, such as greater sensitivity and ease of touch, as the screens become the visible material favoured by mobile phone manufacturers. At the same time, the emergence of electric caps has addressed the fact that in some instances it is not easy to use the finger screen or to feel the awkwardness of the finger screen and to clear the way for the holding of the market。
The uncontroversial capture of the smartphone and tablet markets, and the fact that it is now used without exception in the low- and upper-middle-class mobile phone markets, is an indication of its strong competitiveness, mainly in terms of a more agile, fast and accurate screen response。
The screen, although light-looking, consists of multiple layers of glass, generally four layers of composite glass, but the process is constantly improving as technology develops. Apart from the outer layer of protection, evenly coated membrane conductivity between the inner layer and the gap in the glass allows the surface of an ito to conduct electricity, while the electrodes are distributed on the four feet of the glass. When a person's mobile phone touches the surface of the screen, the bioelectric current in the human body can trigger a charge, and because the conductive material is evenly distributed and the location of the contact point at each of the four angles will result in a difference in the size of the four electrodes, which can be calculated and accurately found。
It is by simulating the biological currents of the human body that the electric pen touches the screen and makes the mobile phone operate on the instructions of the user. And the lower-priced electric pen in the general market, because the exposure process is less sensitive to the current than the mobile phone, is generally relatively large, and it does not send a signal itself, but contact with the touch screen can alter the electrical capacity of the touch screen matrix, prompting mobile phone operations through such changes in the capacity, which we call passive caps. And the other active power pen on the market is that it contains operating circuits, which we call active power pens. It can send a signal to receive the touch screen matrix and, when connected, it can control the volume of the mobile phone and its multiple applications. The sensitivity of passive electric pens has increased significantly and is modest, although it needs to be recharged in a timely manner to keep circuits operational。
And normally, in our daily lives, when we buy spare parts around mobile phones, passive electric pens are cheap enough to wear gloves in winter or at some point. However, the purchase of a high-performance active electric pen is the preferred option for people whose fingers are inconvenient or who are at the forefront of technology。
