Touch screen electromagnetic interference, absorbing material solutions

The projected capacitive touch screen of smart electronic equipment is susceptible to electromagnetic interference EMI, and the electromagnetic interference EMI voltage from internal and external will be capacitively coupled to the touch screen device. These electromagnetic interference voltages will cause the phone movement in the touch screen, which may confuse the measurement of the charge movement when the finger touches the screen. Therefore, the effective design and optimization of the touch screen system depends on the understanding of the interference coupling path and as much as possible. Land reduction or compensation. The interference coupling path involves parasitic effects. For many smart electronic devices, the battery charger constitutes the main interference source of the touch screen. When the operator’s finger touches the touch screen, the generated capacitance causes the charger interference coupling circuit to be closed. The quality of the internal shielding design and whether there is a proper charger grounding design are the key factors that affect the coupling interference of the charger.



The absorbing material is a shielding film with ferrite as the base material. Its main function is to absorb coupled electromagnetic waves to prevent the superposition of electric waves and eliminate unnecessary electric waves in the intelligent electronic system. The absorbing material can be cut into shape and attached to the touch. The anti-electromagnetic interference EMI on the back of the board or on the cable optimizes the performance of the touch screen.
