MULTI-STACK OPTICAL BANDPASS FILM WITH ELECTRO MAGNETIC INTERFERENCE SHIELDING FOR OPTICAL DISPLAY FILTERS

摘要

MULTI-STACK OPTICAL BANDPASS FILM WITH ELECTRO MAGNETIC INTERFERENCE SHIELDING FOR OPTICAL DISPLAY FILTERSAbstractProvided are multi-component films useful as optical display filters. The optical display filters include a multi-layer stack that contains at least two dyads (106), i.e. pairs of layres including an electro-conducting layer (104B) and a dielectric space layer (104C), whereby in at least one of the dyads one transparent, organic layer with a refractive index greater than 1.49 is arranged. The filters have high visible light transmittance, low visible light reflection, and provide electromagnetic interference shielding in the range of 100 1000 MHZ.Figure 1
