As shown in fig. 1 and 2, an embodiment of the present application provides a display panel 1, the display panel 1 having a display area 2 and a pad area 3 located at one side of the display area 2; the display panel 1 includes a plurality of pad groups 4 located in the pad region 3 and distributed in a first direction. The plurality of pad groups 4 includes a first pad group 5 and a second pad group 6 disposed adjacently; a spacer 7 is formed between the first pad group 5 and the second pad group 6. The length of the spacing region 7 in the first direction is gradually changed along the second direction; wherein the second direction is perpendicular to the first direction. The display panel 1 further comprises a virtual pad structure 8 located in the spacer 7; the dummy pad structure 8 is spaced apart from the first pad set 5 and the second pad set 6.
Specifically, in the embodiment of the present application, the first direction is a horizontal direction, and the second direction is a vertical direction.
Specifically, the display area 2 of the display panel 1 is electrically connected to external electronic components through a plurality of pad groups 4 of the pad area 3 to realize a display function. It will be appreciated that the plurality of pad groups 4 are electrically connected to the electronic devices of the display area 2 through wires, and are used for inputting electrical signals to the electronic devices of the display area 2 or outputting electrical signals of the display area 2; while the dummy pad structure 8 is not electrically connected to the electronics of the display area 2 but is present independently in the pad area 3.
Specifically, the plurality of pad groups 4 of the pad area 3 are connected with external electronic components through an adhesive interconnection layer covering the pad area 3; among them, the adhesive interconnect layer has conductivity and adhesiveness, and an Anisotropic Conductive Film (ACF) is generally used as the adhesive interconnect layer.
Specifically, the number of the spacers 7 may be plural, that is, the number of the first pad group 5 and/or the second pad group 6 adjacently disposed may be plural. When the number of the first and second pad groups 5 and 6 is plural, the plural first and second pad groups 5 and 6 may be sequentially staggered, of course, not limited thereto. The embodiment of the present application takes one first pad group 5 and two second pad groups 6 disposed at both sides of the first pad group 5 as an example. It will be appreciated that each spacer 7 is provided with a virtual pad structure 8.
Specifically, the material of the dummy pad structure 8 is the same as that of the first pad set 5 and the second pad set 6, i.e. the dummy pad structure 8 and the first pad set 5 and the second pad set 6 are formed in the same process, which is not limited thereto.
In particular, the first and second pad groups 5, 6 are arranged flush on oppositely arranged first and second sides 9, 10; the length of the spacer 7 in the first direction increases gradually from the first side 9 to the second side 10; the virtual pad structure 8 is arranged flush with the first pad set 5 and the second pad set 6 on the second side 10.
It will be appreciated that the first side 9 and the second side 10 are arranged opposite in the second direction and that the spacer 7 has a trapezoidal shape, i.e. the spacer 7 has a short side 11 at the first side 9 and a long side 12 at the second side 10.
Specifically, the minimum value of the length of the spacer 7 in the first direction is greater than or equal to the preset insulation distance. It will be appreciated that the length of the short side 11 of the spacer 7 at the first side 9 is greater than or equal to the predetermined insulation distance. It should be noted that, the preset insulation distance in the present application is the minimum insulation distance. Specifically, the minimum insulation distance is related to the pad design and ACF model of the display panel 1, and in one embodiment, the minimum insulation pitch is 40 micrometers (um).
It will be appreciated that the minimum distance between the first pad group 5 and the second pad group 6 in the first direction is greater than or equal to the preset insulation distance, and in the embodiment of the present application, the minimum distance between the first pad group 5 and the second pad group 6 in the first direction is located at the first side 9, and the maximum distance between the first pad group 5 and the second pad group 6 in the first direction is located at the second side 10.
Since the minimum insulation distance between the first pad group 5 and the second pad group 6 on the first side 9 needs to be ensured, the distance between the first pad group 5 and the second pad group 6 on the second side 10 is large, and the bonding stress of different positions of the pad area 3 in the pad bonding process is uneven due to the excessive distance, for example, the bonding stress difference between the bonding stress of the first pad group 5 and the second pad group 6 and the bonding stress of the spacer area 7 is large, so that the ACF is not firmly stacked and bonded in the spacer area 7. When the reliability verification is carried out on the display product, at the position with larger space between the first liner group 5 and the second liner group 6, the ACF is easier to release stress to generate gaps, so that water vapor is easier to invade, and reliability risks are easy to generate. Aiming at the problems, the virtual pad structure 8 is arranged in the interval area 7 between the first pad group 5 and the second pad group 6, so that the existence of a larger interval is avoided, the binding stress of the interval area 7 and other positions can be balanced, the ACF is uniformly filled between the pads, the risk of water vapor invasion is effectively reduced, and the reliability of products is improved.
Specifically, the minimum distance D1 between the dummy pad structure 8 and the first pad group 5 in the first direction and the minimum distance D2 between the dummy pad structure 8 and the second pad group 6 in the second direction are greater than or equal to the predetermined insulation distance, and the minimum distance D3 between the dummy pad structure 8 and the second pad group 6 in the first direction and the minimum distance between them are greater than or equal to the predetermined insulation distance. The above design can avoid the interference of the first pad group 5 and the second pad group 6 caused by the too small distance between the virtual pad structure 8 and the first pad group 5 and the second pad group 6.
Specifically, the first pad group 5 includes a plurality of first pads 13 sequentially arranged at intervals in the first direction; the second pad group 6 includes a plurality of second pads 14 arranged at intervals in the first direction in order; the extensions of the first 13 and second 14 pads near the spacer 7 intersect.

It will be appreciated that the width of the pad is the length of the pad in the first direction.
Specifically, the included angle between the extending direction of the virtual pad structure 8 and the second direction is greater than or equal to 0 ° and less than 90 °.
Specifically, the projection shape of the virtual pad structure 8 in the direction perpendicular to the display panel 1 may be rectangular, may be parallelogram, or may be trapezoid, which is not limited to this embodiment of the present application.
Specifically, as shown in fig. 3, the display panel 1 includes a substrate base 15 and a display function layer 16 provided on the substrate base 15; wherein the display function layer 16 is disposed in the display area. It will be appreciated that a plurality of liner groups 4 are provided on the substrate base 15. As shown in fig. 1, in the embodiment of the present application, the display area 2 and the pad area 3 are located on the same plane. In another embodiment, the pad region is located at a side of the substrate base plate, and the present application is not limited to a specific location of the pad region.
