Abstract
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.
