Patent ID: 8630040

Claim:
An optical display filter comprising: a transparent substrate; and a multi-layer stack disposed on the substrate, the stack having at least four dyads, wherein at least one of the dyads is composed of: an electrically-conductive layer; and a transparent organic layer with a refractive index greater than 1.49; wherein the multi-layer stack disposed on the substrate has a reflectance for light having a near-normal incident angle of not greater than 8% of actinic radiation between the wavelengths of 450 nm and 650 nm, a reflectance for light having a 70° incident angle of not greater than 25% of actinic radiation between the wavelengths of 450 nm and 650 nm, a sheet resistivity of less than about 2 ohms/square, and an average electromagnetic interference shielding of at least 35 dB for frequencies in a range of 100 MHz to 1 GHz.
