  • Substrate having an optically transparent EMI/RFI shield
    Patent number: 5489489
    Abstract: A substrate having an optically transparent EMI/RFI shield. A transparent substrate (10) has a thin film metallization pattern (20) on one surface, and some of the pattern is covered with an optically transparent EMI/RFI shield (32). The shield comprises a vapor deposited layer of indium-tin oxide on the substrate surface and on the metallization pattern. The indium-tin oxide is optically transparent. It is patterned to expose one portion (34) of the metallization pattern and to cover a second portion (32) of the metallization pattern. The shield is electrically connected to a part (26) of the metallization pattern that is covered, thus providing electrical shielding and transparency.
