EmiClare PDP
An EmiClare emi window optimised for the low frequency shielding requirement of 42" Plasma
Displays.
EmiClare® PDP windows are available in glass or polycarbonate
with a choice of terminations to suit various bezel and mounting arrangements.
General
Large plasma displays generate significant emi at low frequencies. Neither of the traditional approaches of ITO coating or conventional mesh windows provide a satisfactory solution. They fail to provide sufficient emi attenuation and/or the optical performance is unacceptable.
EmiClare PDP uses our proprietary mesh technology combined with our laminating expertise to produce emi window formats in glass or polycarbonate
which meet the CE mark and FAA/CAA requirements.
