Abstract:
Disclosed herein is a structure of an FPC integrated touch panel. According to preferred embodiments of the present invention, a transparent substrate configured of a flexible transparent film is provided and an extension part protruded to the transparent substrate is integrally formed with the transparent substrate, such that a separate FPC needs not to be manufactured, thereby saving process time and manufacturing costs. In addition, the exemplary embodiments of the present invention bend an inactive area unnecessarily occupying an area of the transparent substrate to a side of the touch panel, thereby implementing a touch panel widening a substantial area of an active region.
Abstract:
A magnetic composition includes first, second, and third magnetic metal particles. The first magnetic metal particles have an average particle size of 10 μm to 28 μm; the second magnetic metal particles have an average particle size of 1 μm to 4.5 μm; and the third magnetic metal particles include insulating layers disposed on surfaces thereof and have a particle size of 300 nm or less. Therefore, eddy current loss of an inductor having a body formed of the magnetic composition may be improved, and high efficiency and inductance of the inductor may be secured.
