The number of the second inclined segments 120a, the number of the second parallel segments 120b included in each row of the output terminal group 120, the number and arrangement of the output terminals 121 in each second inclined segment 120a, the output terminals in each second parallel segment 120b The number of 121 can be adjusted according to the design needs of the driver chip 100 and the matching display panel, to improve the diversity of the arrangement of the output terminals 121 in each row of the output terminal group 120, and to facilitate customized arrangement for various driver chips 100 and display panels. Therefore, the arrangement structure of the output terminal group 120 in the embodiment of the present invention has wide applicability.

In the above embodiment, the number of rows of the output terminal group 120 is one row, but this is not required. In some other optional embodiments, the number of rows of the output terminal group 120 is at least two rows. The number of rows of the output terminal group 120 can be set according to chip design and wiring design requirements, and in some other embodiments, it can also be three rows, four rows and other rows.

When the number of rows of the output terminal groups 120 is at least two rows, optionally, the output terminals 121 of the output terminal groups 120 in adjacent rows are arranged in a staggered manner in a direction parallel to the first side B1 . When the driver chip 100 is integrated with the display panel, the output terminals 121 of each row of output terminal groups 120 need to be electrically connected to the second fan-out line. The directions are staggered, so that the second fan-out line connected to the output terminals 121 of one row of the output terminal groups 120 can be extended and arranged through the gaps between the adjacent output terminals 121 in the adjacent row of the output terminal groups 120 to avoid being connected with different rows of output terminals 120.

The distance from the input terminal 111 to the first side B1 is the distance from the center of the input terminal 111 to the first side B1. The input terminals 111 located at both ends in the direction parallel to the second side B2 are arranged obliquely toward the first side B1, the output terminals 121 located at both ends in the direction parallel to the second side B2 are arranged obliquely toward the second side B2, and the end The distance D3 from the input terminal 111 of the end portion to the first side B1 is smaller than the distance D4 from the output terminal 121 of the end portion to the first side B1, so that the input terminal can be arranged in a partial area of the driving chip 100 in the direction perpendicular to the second side B2. The group 110 can also arrange the output terminal group 120, so as to improve the effective utilization rate of the area occupied by the driving chip 100 to a greater extent. When the driver chip 100 is integrated with the display panel, the distance between the second side B2 of the driver chip 100 and the outer contour of the display panel can be reduced, and the distance between the first side B1 of the driver chip 100 and the display area of the display panel can also be reduced, Therefore, the width of the non-display area on the side of the integrated driving chip 100 of the display panel can be further reduced, that is, the width of the frame of the display panel at the side can be further reduced.
