EMI SHIELDING

Electro Magnetic Interference (EMI) Shielding

  • Conductive Transparent Glass for TFT Displays
  • For military, medical, marine, avionics, test and measurement
  • Film and glass
Sensitive medical, military or aerospace applications are subject to strict regulations concerning electromagnetic interference. In order to meet these requirements with our TFT displays and to shield the interference of the TFT cell, we use conductive transparent EMI mesh foil laminated to glass or plastic substrates such as acrylic, polycarbonate or polyester (PET) etc. The silver-coated gasket, busbar are used for grounding via the TFT display bezel.
Applications
  • Military displays
  • Medical equipment and MRI rooms
  • Marine
  • Avionics
  • In-flight entertainment displays
  • Secure TEMPEST equipment
  • Test and measurement
Fitting options
  • Optical Bonding
  • Cover window : PMMA, PC, Glass and etc…
  • Extra contact edge options
    – EMI Gasket : Silver busbar, Copper edges for grounding
