Abstract
The present disclosure relates to an electromagnetic induction film and a manufacturing method thereof, an electromagnetic induction panel and a manufacturing method thereof, and a touch display device. The method for manufacturing the electromagnetic induction film may include: arranging a plurality of first conductors in parallel along and spaced apart along a first direction on a substrate; arranging an insulating layer on the plurality of first conductors; arranging a plurality of second conductors in parallel and spaced apart along the first direction on the insulating layer; and electrically connecting head end areas of the first conductors to head end areas of the second conductors and electrically connecting tail end areas of the first conductors to tail end areas of the second conductors to form an electromagnetic induction coil spirally surrounding the insulating layer.
