Transparent shielding foil, is widely used for applications of EL panel, LCD EMI shielding, touch screen, flexible solar cell etc.
Transparent EMI/RFI-shielding foil is a polyester film with a transparent conductive coating. The foil provides excellent electric and electromagnetic shielding of 40-70 dB at 10 KHz to 300 MHz and 25-40 dB from 300 MHz to 22 GHz.
In addition to EMI/RFI/EMC shielding it is also used for grounding and static discharge applications. Typical applications are transparent shielding panels for visual displays in instrumentation equipment, control panels and computers. The light transmission is 65-95%, depending on the electrical conductivity.
