Display apparatus with sensing by electromagnetic induction and by self-capacitance

A display apparatus comprising:

• 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, wherein
• the first electrodes are provided in the same layer as the detection electrodes,
• the detection electrodes arranged in the first direction are provided adjacent to one of the first electrodes in the second direction,
• each of the detection electrodes includes a plurality of partial detection electrodes,
• the partial detection electrodes are electrically coupled to a common detection electrode line via individual detection electrode lines coupled to the respective partial detection electrodes, and
• each of the first electrodes is provided between the partial detection electrodes adjacent to each other in the second direction.
