ELECTROMAGNETIC INDUCTION TABLET STRUCTURE, METHOD OF MANUFACTURING THE SAME, AND ELECTROMAGNETIC HANDWRITING INPUT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic induction tablet which can satisfy the requirement for miniaturization of a product by effectively reducing the thickness of the entire product, a method of manufacturing the same, and an electromagnetic handwriting input device.SOLUTION: The electromagnetic induction tablet structure includes a multilayer substrate, a first cover unit, and a second cover unit. The multilayer substrate has a first outermost conductive layer and a second outermost conductive layer on two opposite outermost surfaces thereof. The first cover unit is disposed on the first outermost conductive layer of the multilayer substrate. The second cover unit is disposed on the second outermost conductive layer of the multilayer substrate. The second cover unit includes a wave-absorbing material layer. The first cover unit includes a first insulating layer directly formed on the first outermost conductive layer so as to be directly connected to the first outermost conductive layer. The second cover unit includes a second insulating layer directly formed on the second outermost conductive layer so as to be directly connected to the second outermost conductive layer.
