Claim 9:
10. A method for manufacturing the substrate according to claim 1, the method comprising:
forming at least one first strip-shaped groove corresponding to each driving backplane to be cut in a third surface of a driving backplane motherboard which includes at least one driving backplane to be cut, wherein the driving backplane to be cut has a display area and at least one peripheral region located on a periphery of the display area; and each first lead group and a corresponding second lead group of the driving backplane to be cut are disposed in one peripheral region; and each first strip-shaped groove is in contact with a corresponding peripheral region where a first lead group and a second lead group are disposed;
forming a plurality of first connecting lines insulated from each other in a region in which the first strip-shaped groove is located, wherein each first connecting line extends to a surface of at least one first lead and is in contact with the at least one first lead;
forming at least one second strip-shaped hole in a fourth surface of the driving backplane motherboard that is opposite to the third surface, each second strip-shaped hole being connected to a corresponding first strip-shaped groove;
forming a plurality of second connecting lines insulated from each other in a region in which the second strip-shaped hole is located, wherein each second connecting line is in contact with a corresponding first connecting line, and the second connecting line extends to a surface of at least one second lead and is in contact with the at least one second lead; and
cutting the driving backplane motherboard to obtain at least one driving backplane, and the plurality of first connecting lines and the plurality of second connecting lines that are formed on at least one side face of each driving backplane.
