Now is the era of the development of information technology and the era of the Internet. In the Internet era, there is no shortage of electronic products, which have short update cycles and complete functions, and bring a lot of fun to people's lives. But when we use electronic products, the touch screen will be subject to various electromagnetic interferences over time. Because interference is mainly caused by the interference signals generated by electronic devices through conductive media or public power lines, it means that the interference signals generated by electronic devices transmit the interference signals to another electrical network or electronic device through space, in order to prevent some electronic products from being generated. The electromagnetic interference affects or destroys the normal operation of other electronic equipment. It is necessary to paste absorbing materials on the conduction path to cut off the interference path, and paste absorbing materials on the radiation source to cut off the interference source.
Projection touch screens of smart electronic devices are susceptible to electromagnetic interference. Electromagnetic interference voltages from internal and external sources will be capacitively coupled to the touch screen device. These electromagnetic interference voltages can cause movement in the touch screen, confound the movement of electric charges when the finger touches the screen, and affect the sensitivity and touch accuracy of the touch screen. The solution can be to use absorbing materials to absorb electromagnetic waves and eliminate interference.
The interference coupling path involves parasitic effects. For many smart electronic devices, the charger constitutes the main interference source of the touch screen. When a finger touches the touch screen, the generated capacitance makes the interference coupling of the charger close, and the internal shielding design of the charger Quality and proper charger grounding design are the key factors that affect charger interference.
The main function of the absorbing material is to absorb the coupled electromagnetic waves to prevent the superposition of electric waves and eliminate the redundant electric waves in the intelligent electronic system. The absorbing material can be cut and attached to the back of the touch panel or cable to resist electromagnetic interference and optimize the performance of the touch screen. The wave absorbing material also has the characteristics of light weight, softness and not fragile, wide absorption frequency, good absorption performance, strong weather resistance, anti-aging, easy bending, easy processing and cutting, moisture resistance, pressure resistance, long-term use, non-toxic and environmental protection and so on.
