1. An input/output panel comprising:

  • a gate wiring;

    a first wiring electrode;

    a second wiring electrode;

    a current sensing circuit; and

    a pixel,wherein the first wiring electrode is parallel to and directly electrically connected to the gate wiring via a third wiring electrode in a contact region,wherein the second wiring electrode intersects with the gate wiring,wherein the first wiring electrode and the second wiring electrode intersect and a capacitance is generated at the intersection,wherein the current sensing circuit is electrically connected to the second wiring electrode,wherein the current sensing circuit is configured to sense a change in the capacitance for determining a touch,wherein the pixel comprises a transistor and a display element,wherein the transistor comprises a gate electrode, a source electrode, and a drain electrode,wherein the gate electrode is electrically connected to the gate wiring,wherein the display element comprises a third electrode and a liquid crystal material, andwherein the third electrode is electrically connected to the source electrode or the drain electrode.
