Substrate and electronic apparatus

A substrate having a plurality of edges;

• the substrate comprising a device region and at least one bonding region, and the bonding region being disposed proximate to any edge of the substrate relative to the device region;
• the substrate comprising:
• a base;
• a plurality of device groups located on a side of the base and located in the device region, wherein the plurality of device groups are arranged in a first direction and a second direction, the first direction intersects the second direction, and the first direction and the second direction are parallel to the base;
• a device group includes at least one electronic element;
• a plurality of signal line groups located on a same side of the base as the plurality of device groups, wherein a signal line group includes a plurality of signal lines, the plurality of signal lines all extend in the second direction, and the plurality of signal lines are disposed at intervals in the first direction;
• any signal line extends from the bonding region to the device region, and any signal line is electrically connected to a column of device groups arranged in the second direction;
• and
• a plurality of bridging portions located on the same side of the base as the plurality of device groups, wherein at least one bridging portion is located in the device region, and the at least one bridging portion includes a conductive portion;
• wherein
• the at least one bridging portion satisfies at least one of:
• at least two signal lines in at least one signal line group are electrically connected by a conductive portion;
• and at least one signal line in at least one signal line group includes at least two sub-portions disposed at intervals in the second direction, and two adjacent sub-portions in a same signal line are electrically connected by a conductive portion;
• and
• at least part of a side of any bridging portion away from the base is capable of reflecting light.
