Claim 14:
15. The array substrate according to claim 14, wherein the first direction is parallel to the bearing surface of the base substrate and the extension direction of any side of the base substrate;
in the sector pad group, a distance between any two adjacent pads at an end proximal to the display region is not greater than a distance between the two pads at an end distal from the display region;
an angle defined between extension directions of any two adjacent pads in the sector pad group is a target angle; an angle defined between extension directions of two pads disposed at both ends ranges from 10 degrees to 20 degrees; and an angle defined between the extension direction of the pad at any end and a second direction ranges from 5 degrees to 10 degrees, wherein the second direction is parallel to the bearing surface of the base substrate and perpendicular to the first direction;
any one of the pads comprises a first edge and a second edge that are oppositely disposed and extended along the first direction, and the first edge is more proximal to the display region relative to the second edge; and in the any two adjacent pads, a dimension of the first edge of the pad distal from a central axis of the sector pad group is greater than a dimension of the first edge of the pad proximal to the central axis of the sector pad group; wherein in the sector pad group, a dimension of the first edge of the pad disposed at any end is 2 μm to 6 μm greater than a dimension of the first edge of the pad most proximal to the central axis of the sector pad group; wherein a length of the first edge ranges from 25 μm to 35 μm; wherein in the sector pad group, a distance between a center of the first edge of one pad and a center of the first edge of the other pad in one pair of adjacent pads is equal to a distance between a center of the first edge of one pad and a center of the first edge of the other pad in another pair of adjacent pads; the first edges of pads are in a same line, and the second edges of pads are is in a same line;
any one of the pads further comprises a third edge and a fourth edge that are oppositely disposed to be parallel to each other, the third edge is connected to one end of the first edge and one end of the second edge, and the fourth edge is connected to the other end of the first edge and the other end of the second edge; any two pads comprises an equal number of connection vias, and a shape of each connection via is a parallelogram with one side extending along the first direction; and
any two of the connection vias have a same dimension along both the first direction and the second direction, wherein the second direction is parallel to the bearing surface of the base substrate and perpendicular to the first direction.
