 EMI Display Window for Plasma, Emiclare

An EmiClare emi mesh display filter window is optimised for the low frequency shielding requirement of 42" Plasma Displays.

EmiClareŽ PDP emi display filter windows are available in glass or polycarbonate with a choice of terminations to suit various bezel and mounting arrangements. Click here for the full Emiclare emc filter range.


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.
