For example, a first region may also be referred to as a second region, and similarly, a second region may also be referred to as a first region, without departing from the scope of embodiments of the present application.
The applicant has provided a solution to the problems existing in the prior art by intensive studies.
Fig. 1 is a schematic diagram of a display panel according to an embodiment of the application.
As shown in fig. 1, the display panel 001 provided in the embodiment of the application includes a display area AA and a non-display area NA, and the non-display area NA surrounds the display area AA. The display area AA is a region of the display panel 001 mainly used for performing light emitting display, and the non-display area NA may be a region of the display panel 001 where peripheral wiring, peripheral circuits, and a printed circuit board or a flexible circuit board are bonded.
The non-display area NA includes a plurality of first traces 10, and the first traces 10 are at least part of peripheral traces in the display panel 001. The first trace 10 extends in the non-display area NA, and the first trace 10 may be electrically connected to and transmit corresponding signals to the trace in the display area AA, and/or the first trace 10 may also be electrically connected to and transmit corresponding signals to peripheral circuits in the non-display area NA.
In addition, the non-display area NA includes a plurality of first alignment marks 20, and when the display panel 001 is attached to other components by the machine, the alignment marks on the components to be attached to the display panel 001 or the alignment marks on the machine are attached to the first alignment marks 20 after being aligned, so that the attachment yield of the display panel 001 and the components to be attached can be ensured.
Components that interface with the display panel include, but are not limited to: printed circuit boards, flexible printed circuit boards, polarizers, protective films, and the like. The first alignment mark 20 may be an alignment mark on the display panel 001 that is required when the display panel 001 is attached to at least one of a printed circuit board, a flexible printed circuit board, a polarizer, and a protective film.
Fig. 2 is a schematic diagram showing the bonding of the display panel and the flexible printed circuit board. Hereinafter, the display panel 001 and the flexible printed circuit board 002 are bonded to each other as an example. For convenience of explanation, the alignment mark on the flexible printed circuit board 002 will be referred to as a second alignment mark 20'.
As shown in fig. 2, when the display panel 001 and the flexible printed circuit board 002 are attached, the attaching machine first recognizes the first alignment mark 20 on the display panel and the second alignment mark 20 'on the flexible printed circuit board 002, then aligns the first alignment mark 20 and the second alignment mark 20' on the flexible printed circuit board 002, and then presses the display panel 001 and the flexible printed circuit board 002. In the bonding process of the display panel 001 and the flexible printed circuit board 002, the alignment accuracy of the first alignment mark 20 and the second alignment mark 20' directly affects the bonding yield of the display panel 001 and the flexible printed circuit board 002. And whether the laminating machine can accurately identify the position of the first alignment mark 20 can influence the alignment accuracy of the machine to the first alignment mark 20 and the second alignment mark 20'.
Fig. 3 is a schematic diagram of a display panel according to the present application.
The inventor has analyzed the technical problems mentioned in the background art section of the present application, and as shown in fig. 3, in the process of identifying the first alignment mark 20 by the bonding machine, the first wires 10 around the first alignment mark 20 interfere with the identification process, so that the bonding machine cannot accurately identify the first alignment mark 20. This is mainly because the shape of the edge of the first alignment mark 20 facing the first trace 10 is similar to the shape of the portion of the first trace 10 near the first alignment mark 20, for example, as shown in fig. 3, the shape of the edge of the first alignment mark 20 facing the first trace 10 in the display panel is a broken line shape and the portion of the first trace 10 adjacent to the first alignment mark 20 is also a broken line shape, which results in the attaching machine recognizing the first trace 10 as the edge of the first alignment mark 20 and misidentifying the first alignment mark 20.
The above problem is further aggravated when the frame of the display panel 001 is narrow. This is mainly because, when the frame of the display panel 001 is narrower, the distance between the first alignment mark 20 and the first trace 10 is smaller, and the risk of the bonding machine recognizing the first trace 10 as the edge of the first alignment mark 20 is further increased.
In order to enable the bonding machine to accurately identify the first alignment mark 20, the distance between the first alignment mark 20 and the adjacent first trace 10 may be increased, but this may result in an increase in the width of the non-display area NA of the display panel 001.
As shown in fig. 1, the first trace 10 includes a first portion 11 (a thickened portion of the first trace 10 shown in fig. 1) adjacent to a first alignment mark 20, and the first alignment mark 20 includes a first edge 21 (a thickened portion of the first alignment mark 20 shown in fig. 1) facing the first trace 10. In the embodiment of the present application, the extending direction of the first edge 21 intersects with the extending direction of the first portion 11, that is, the extending direction of the first edge 21 opposite to the first trace 10 in the first alignment mark 20 is not parallel to the extending direction of the first portion 11.
In the embodiment of the present application, by setting the extending direction of the first edge 21 and the extending direction of the first portion 11 to intersect, the similarity between the shape of the first edge 21 near the first trace 10 and the shape of the first portion 11 in the first alignment mark 20 is destroyed. In the process of identifying the first alignment mark 20 by the laminating machine, the first wiring 10 can not interfere with the first alignment mark 20 any more, and therefore the laminating precision of the display panel 001 and other components is improved. Meanwhile, by the method of the embodiment of the application, the interference caused by the first wiring 10 when the first alignment mark 20 is identified by the laminating machine is avoided, so that the distance between the first alignment mark 20 and the adjacent first wiring 10 is not required to be increased, and the width of the non-display area NA of the display panel 001 is smaller.
In a corresponding implementation manner of the embodiment of the present application, as shown in fig. 1, the shape of the first edge 21 of the first alignment mark 20 near the first trace 10 and the shape of the adjacent first portion 11 are both linear and the extending directions of the two intersect. By setting the shape of both the first edge 21 and the first portion 11 to be rectilinear, the implementation of the etching process is facilitated.
Fig. 4 is a schematic diagram of shapes of a first alignment mark and a first trace in a display panel according to an embodiment of the present application.
In a corresponding implementation of the embodiment of the application, as shown in fig. 4, the curvature of the first edge 21 is different from the curvature of the first portion 11. That is, one of the first edge 21 and the first portion 11 has a larger curvature and one has a smaller curvature. For example, as shown in fig. 4, the curvature of the first edge 21 and the first portion 11 is greater than 0, and the curvature of the first edge 21 is greater than the curvature of the first portion 11.
Fig. 5 is a schematic diagram of shapes of a first alignment mark and a first trace in a display panel according to an embodiment of the present application, and fig. 6 is a schematic diagram of shapes of a first alignment mark and a first trace in a display panel according to an embodiment of the present application.
In one embodiment of the present application, as shown in fig. 5 and 6, the first portion 11 is linear or polygonal, and the first edge 21 is curved. It will be appreciated that in the present embodiment, the first portion 11 of the first trace 10 adjacent to the first alignment mark 20 is formed by a straight line with a curvature of 0, and the first edge 21 of the first alignment mark 20 facing the first trace 10 is curved with a curvature greater than 0.
For example, as shown in fig. 5, the first portion 11 of the first trace 10 near the first alignment mark 20 is linear with a curvature of 0, and the first edge 21 of the first alignment mark 20 facing the first trace 10 is curved with a curvature of greater than 0.
For example, as shown in fig. 6, the first portion 11 of the first trace 10 adjacent to the first alignment mark 20 is formed in a polygonal line shape composed of a straight line shape having a curvature of 0, and the first edge 21 of the first alignment mark 20 facing the first trace 10 is curved with a curvature of more than 0.
The first portion 11 of the first trace 10 provided in this embodiment has an obvious shape difference from the first edge 21 of the adjacent first alignment mark 20, which is more beneficial to the recognition of the first alignment mark 20 and the first trace 10 by the bonding machine.
In one implementation of the present embodiment, as shown in fig. 5 and 6, the projected shape of the first alignment mark 20 is a circle.

It should be noted that, in the plurality of first alignment marks 20 included in the display panel provided in the present embodiment, a part of the projection shapes of the first alignment marks 20 may be one shape, and a part of the projection shapes of the first alignment marks 20 may be another shape.
In the present embodiment, the projected shape of the first alignment mark 20 is at least one of a circle, an ellipse, a semicircle, a fan, and a crescent.

That is, the first area NA1 may be at least one of a left non-display area NA, a right non-display area NA, an upper non-display area NA, and a lower non-display area NA of a rectangular display panel or a rounded rectangular display panel; alternatively, the first area NA1 may be a non-display area NA having a linear shape in a non-rectangular display panel.
In this embodiment, at least a portion of the first alignment marks 20 are disposed in the first area NA1, and at least a portion of the first traces 10 extend to the first area NA1. Wherein, the first alignment mark 20 disposed in the first area NA1, the first edge 21 of the first alignment mark 20 is curved; the first trace 10 extends along a straight line in the first area NA1. That is, the first trace 10 in the linear first area NA1 is kept to extend along the straight line as much as possible, so that the first area NA1 can be ensured to have a smaller width as much as possible; the first alignment mark 20 is curved toward the first edge 21 of the first trace 10, so that the bonding machine can accurately distinguish the first alignment mark 20 from the first trace 10 when identifying the first alignment mark 20.

In one embodiment of the present application, as shown in fig. 16 and 17, the first portion 11 is curved and the first edge 21 is linear or broken-line. It will be appreciated that in the present embodiment, the first portion 11 of the first trace 10 adjacent to the first alignment mark 20 has a curve shape with a curvature greater than 0, and the first edge 21 of the first alignment mark 20 facing the first trace 10 is formed of a straight line with a curvature of 0.

It should be noted that, the display panel may be provided with a plurality of first alignment marks 20, and the functions of the plurality of first alignment marks 20 may be the same or different.
In one case, as shown in fig. 20 to 22, the shapes of the plurality of first alignment marks 20 included in the display panel may be the same, and the attaching machine only needs to identify the first alignment mark 20 with one shape, which is easy to implement.
Fig. 23 is a schematic diagram of a display panel according to an embodiment of the application.
In one case, as shown in fig. 23, a part of the first alignment marks 20 among the plurality of first alignment marks 20 included in the display panel may have a shape different from that of another part of the first alignment marks 20. For example, as shown in fig. 23, the non-display area NA of the display panel includes a first area NA1 and a second area NA2, the first alignment mark 20 and the first trace 10 are disposed in each of the first area NA1 and the second area NA2, and the first alignment mark 20 in each of the first area NA1 and the second area NA2 has a different shape and the first portion 11 has a different shape. The shape of the first register mark 20 may be determined according to the position where the first register mark 20 is provided and/or the shape of the first portion 11 adjacent to the first register mark 20.
Fig. 24 is a schematic diagram of a display panel according to an embodiment of the application.
In one embodiment of the present application, as shown in fig. 24, at least a portion of the first alignment mark 20 is disposed on a side of the first trace 10 away from the display area AA, that is, the portion of the first alignment mark 20 is closer to the edge of the display panel 001 than the first trace 10, so that reliability of the first trace 10 can be ensured.
Fig. 25 is a schematic diagram of a display device according to an embodiment of the application.
As shown in fig. 25, an embodiment of the present application further provides a display device including the display panel provided in any one of the above embodiments. The display device provided by the embodiment of the application can be a mobile phone, and in addition, the display device provided by the embodiment of the application can also be a display device of a computer, a television and the like.
In the embodiment of the present application, by setting the extending direction of the first edge 21 and the extending direction of the first portion 11 to intersect, the similarity between the shape of the first edge 21 near the first trace 10 and the shape of the first portion 11 in the first alignment mark 20 is destroyed. In the process of identifying the first alignment mark 20 by the laminating machine, the first wiring 10 can not interfere with the first alignment mark 20 any more, and therefore the laminating precision of the display panel and other components in the display device is improved. Meanwhile, by the method of the embodiment of the application, the interference caused by the first wiring 10 when the first alignment mark 20 is identified by the laminating machine is avoided, so that the distance between the first alignment mark 20 and the adjacent first wiring 10 is not required to be increased, and the non-display width of the display device is smaller.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the application.
