WIPO Patent Application WO/2016/043434
Kind Code:
A1
Abstract:
Disclosed is a multi-touch device detecting a touch input by using a passive element. The device comprises: a plurality of driving electrodes; a plurality of detection electrodes; a plurality of impedances positioned at an intersecting point of the plurality of driving electrodes and the plurality of detection electrodes; and a control unit selecting a first driving electrode and a first detection electrode from the plurality of driving electrodes and the plurality of detection electrodes, outputting a first voltage on the first driving electrode, outputting a second voltage on at least one of the remaining driving electrodes and at least one of the remaining detection electrodes, and detecting a touch input on a first intersecting point of the first driving electrode and the first detection electrode on the basis of a detection voltage detected from the first detection electrode.
