Classification: CPC H | IPC H

Claim 0:
1. A substrate, comprising:
a driving backplane, having a display area and at least one peripheral region located on a periphery of the display area, the driving backplane including:
a base substrate, including a first surface and a second surface opposite to the first surface; and
at least one first lead group disposed on the first surface of the base substrate, each first lead group including a plurality of first leads; and
at least one second lead group disposed on the second surface of the base substrate, a first lead group and a corresponding second lead group being disposed in a peripheral region; and each second lead group including a plurality of second leads;

a plurality of first connecting lines insulated from each other, the plurality of first connecting lines being disposed on at least one side face of the driving backplane adjacent to at least one peripheral region where the at least one first lead group and the at least one second lead group are disposed, each first connecting line being electrically connected to at least one first lead; and
a plurality of second connecting lines insulated from each other, the plurality of second connecting lines being disposed on the at least one side face of the driving backplane, and each second connecting line being electrically connected to at least one second lead, and being in contact with a corresponding first connecting line, wherein an interface between the first connecting line and the corresponding second connecting line is a region where an end face of the first connecting line and an end face of the corresponding second connecting line meet; and
the interface between the first connecting line and the corresponding second connecting line is substantially located at a position at half a thickness of the base substrate.
