  • Touch Display Apparatus
    Publication number: 20230341962
    Abstract: A touch display apparatus is provided. The touch display apparatus may include a touch sensor on an encapsulating unit covering light-emitting devices. The touch sensor may include touch electrodes and bridge electrodes electrically connecting between the touch electrodes. Each of the touch electrodes may be electrically connected to the corresponding touch pad by one of touch routing lines. A guard line may be disposed between the touch electrodes and each touch routing line. A signal applied to the guard line may be different from a signal applied to adjacent touch routing line. Thus, in the touch display apparatus, a reduction in touch sensitivity due to a touch driving signal or a touch sensing signal applied by the touch routing lines may be prevented or at least reduced.
