Claim 14:
15. The method according to claim 10, wherein
forming the plurality of first connecting lines insulated from each other includes:
forming a first metal layer on the third surface of the driving backplane motherboard by using a sputtering process, the first metal layer including a portion filling the first strip-shaped groove;
forming a first photoresist layer on the first metal layer;
exposing and developing the first photoresist layer; and
etching the first metal layer to form the plurality of first connecting lines insulated from each other in the region in which the first strip-shaped groove is located;
and/or
forming the plurality of second connecting lines insulated from each other includes:
forming a second metal layer on the fourth surface of the driving backplane motherboard by using the sputtering process, the second metal layer including a portion filling the second strip-shaped hole;
forming a second photoresist layer on the second metal layer;
exposing and developing the second photoresist layer; and
etching the second metal layer to form the plurality of second connecting lines insulated from each other in the region in which the second strip-shaped hole is located.
