Title:
ELECTROMAGNETIC SHIELDING FILM
Document Type and Number:
WIPO Patent Application WO/2020/253290
Kind Code:
A1
Abstract:
Disclosed is an electromagnetic shielding film, comprising a support layer and N conductive layers. The support layer comprises a first side surface and a second side surface disposed opposite to each other. The N conductive layers are stacked on the first side surface and/or the second side surface, where N ≥ 2. Each of the conductive layers has a conductive grid, the conductive grid comprises grid-shaped recesses and a conductive material filled in the recesses, and at least two of the N conductive layers include conductive materials providing shielding against different wavebands. The different layers have different conductive materials, and thus can provide shielding against different wavebands, thereby widening the range of wavebands blocked by the electromagnetic shielding film, and meeting market demands.
