Substrate and electronic device

A substrate has a plurality of edges. The substrate comprises a device area and at least one binding area, and the binding area is close to any edge of the substrate relative to the device area. The substrate comprises a substrate, a plurality of device groups, a plurality of signal line groups and a plurality of bridging parts. The plurality of device groups are located on one side of the substrate, and the plurality of device groups are located in the device region. The plurality of device groups are arranged along a first direction and a second direction, respectively. The first direction and the second direction intersect, and the first direction and the second direction are parallel to the substrate. One device group includes at least one electronic component. Each signal line group comprises a plurality of signal lines. The plurality of signal lines extend along the second direction, and the plurality of signal lines are arranged at intervals along the first direction. Any signal line extends from the b
