  • Patent number: 11334179
    Abstract: The present disclosure relates to display technology and, particularly, to a display panel and a display device. In the display panel, a bridging connection layer includes multiple bridge electrodes and a touch electrode layer includes multiple first touch electrodes and multiple second touch electrodes. A first electrode unit of each first touch electrodes includes a first electrode subsection. A vertical projection of the first electrode subsection on a plane where the bridging connection layer is located is within a cover of a bridge electrode. In one embodiment, each bridge electrode includes a bridge electrode terminal and a bridge trace, in a second direction where multiple second electrode units of each second touch electrode are arrange, and extension length of the bridge electrode terminal is greater than a width of the bridge trace, and a first corner is formed at a joint of the bridge electrode terminal and the bridge trace.

  • Publication number: 20210373691
    Abstract: A display panel includes a display function layer and a touch function layer. The touch function layer includes a bridging connection layer, an insulating layer and a touch electrode layer. The bridging connection layer includes multiple bridge electrodes. The touch electrode layer includes multiple first touch electrodes and multiple second touch electrodes. The first touch electrode includes multiple first electrode units electrically connected to each other. The second touch electrode includes multiple second electrode units electrically connected to each other. In each of the multiple first touch electrodes, any two adjacent first electrode units are electrically connected through the bridge electrode. The first electrode unit includes a first electrode subsection. A vertical projection of the first electrode subsection on a plane where the bridging connection layer is located is within a coverage of the bridge electrode.
