The projected capacitive touch screen of smart electronic devices is susceptible to electromagnetic interference, and the EMI voltage from internal and external electromagnetic interference will be capacitively coupled to the touch screen device. These electromagnetic interference voltages can cause phone movement in the touch screen, which may confuse the measurement of charge movement 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.
First of all, let's see what is high permeability absorbing material: high permeability refers to the…
