MULTI-INPUT PAD FOR SIMULTANEOUSLY SENSING CAPACITIVE TOUCH AND INDUCED ELECTROMAGNETIC FIELD INPUT AND INPUT SYSTEM

摘要

The present invention relates to a multi-input pad for operating in a capacitive sensing mode and in an induced electromagnetic field sensing mode, thereby simultaneously sensing a capacitive touch and an induced electromagnetic field input, the multi-input pad comprising: a plurality of first patterns extending in a first direction in a predetermined sensing area; a plurality of second patterns extending in a second direction in the sensing area; a plurality of third patterns extending in the second direction in the sensing area; and a common loop surrounding at least a part of the sensing area, the other ends of the third patterns being connected to the common loop.
