Abstract:
The present invention relates to an electromagnetic shielding sheet capable of improving reliability. Particularly, the present invention provides a composite magnetic sheet for electromagnetic shielding structured such that an independent soft magnetic sheet, which has a low surface roughness, is laminated on the outermost surface of a soft magnetic sheet having a lamination structure, thereby implementing laminated composite sheets having different surface roughness or porosity characteristics; as a result, the reliability in an external hazardous environment, such as saline water, can be substantially enhanced while maintaining the efficiency of electromagnetic shielding.

Disclosed is a display device. The display device includes: a light source; an optical sheet into which light is incident from the light source; a display panel disposed on the optical sheet and including an effective display region and a non-effective display region around the effective display region; and a light conversion/light-blocking sheet corresponding to the non-effective display region.
Abstract:
A soft magnetic layer for a receiving antenna of a wireless power receiving apparatus includes a first soft magnetic member containing a Mn—Zn ferrite material, and a second soft magnetic member containing a Ni—Zn ferrite material. Accordingly, electromagnetic energy collecting performance of the receiving antenna of the wireless power receiving apparatus is improved, and thereby power transmission efficiency is maximized.
