  • Touch substrate, touch display panel and display apparatus
    Patent number: 12487720
    Abstract: The present disclosure provides a touch substrate, a touch display panel and a display apparatus. A line width of at least a part of a bridging electrode in a spacing region between a sub-electrode of a corresponding first touch electrode and a corresponding second touch electrode in a first direction is greater than a line width of the corresponding second touch electrode, so that a routing length of an edge of the bridging electrode in the spacing region can be increased, or so that a certain gap exists between the sub-electrode and the residual metal at the edge of the bridging electrode, the sub-electrode is insulated from the residual metal, the short circuit between the first touch electrode where the sub-electrode is located and the second touch electrode due to the metal residue can be avoided, and the touch quality of the touch substrate can be ensured.
