Abstract:
According to an aspect, a display apparatus includes: a substrate; a plurality of pixel electrodes; a plurality of detection electrodes arranged in a matrix in a display area of the substrate; a plurality of detection electrode lines coupled to the respective detection electrodes; a plurality of first electrodes provided in the same layer as the detection electrodes or the detection electrode lines and extending in a first direction; a plurality of switching elements coupled to the respective pixel electrodes; a plurality of signal lines coupled to the switching elements and extending in a second direction crossing the first direction; a coupling member provided in a peripheral area outside the display area and configured to couple ends of the first electrodes to each other; and a drive circuit configured to output a first drive signal in a first sensing period in which an electromagnetic induction method is used.
