Abstract

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.

Description

technical field [0001] The present invention relates to a multi-input board and an input system for simultaneously sensing finger touch and electronic pen manipulation, and more particularly, to a multi-input board for simultaneously sensing capacitive touch and inductive electromagnetic field input and comprising the multi-input board input system. Background technique [0002] As a conventional technology for the manipulation of an electronic pen (e-pen) that simultaneously senses finger touch and emits an induced electromagnetic field, Korean Patent No. 1027672 entitled "Tablet for simultaneously sensing positions of a finger and apointer with a resonance circuit" was proposed . [0003] In traditional techniques, such as figure 1 As shown, by laminating the substrate forming the first wire antenna 111 and the first wire electrode 121 and the substrate forming the second wire antenna 112 and the second wire electrode 122, it is possible to detect motion along the first ...
