APPARATUS AND METHOD FOR DETECTING ADJACENT OBJECT AND METHOD OF DRIVING ELECTRONIC DEVICE

摘要

Provided are an apparatus and method for detecting an adjacent object, and a method of driving an electronic device. The apparatus includes a substrate, a plurality of first electrodes including a plurality of first electrodes disposed to extend in a first direction on one surface of the substrate, a plurality of second electrodes disposed alternately and in parallel with the first electrodes on the surface of the substrate to form capacitors together with the first electrodes, a signal source configured to generate electrical signals, a detector configured to detect current signals output when the electrical signals are applied to the capacitors, and a controller configured to connect the signal source to the first electrodes and the detector to the second electrodes.

1. An apparatus for detecting an adjacent object, comprising:
a substrate; a plurality of first electrodes including one or more 1a electrodes and one or more 1b electrodes disposed to extend in a first direction on one surface of the substrate; a plurality of second electrodes disposed alternately and in parallel with the first electrodes on the surface of the substrate to form capacitors together with the first electrodes; a signal source configured to generate electrical signals; a detector configured to detect current signals output when the electrical signals are applied to the capacitors; and a controller configured to connect the signal source to the first electrodes and the detector to the second electrodes, wherein the signal source applies out of phase signals with each other to the 1a electrodes and the 1b electrodes.
