[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0039] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0040] The embodiments of the present invention provide a display panel. Three through holes are provided in the display area of the display panel. The display panel is a multi-layer stacked structure, and the through holes penetrate at least part of the film layers of the display panel. Then, there are no pixels in the area where the through holes are located and normal display cannot be performed. Some functional devices, such as photosensitive devices such as cameras, can be provided in the area where the through holes are located. In this way, there is no need to occupy the border of the display panel to provide these devices, and the border width of the display panel can be reduced. In the embodiments of the present invention, the relative positions of the three through holes are designed to improve the overall symmetry of the displayable area after the through holes are provided, so as to improve the display effect.

[0041] In some embodiments of the present invention, Figure 1 is a partial schematic diagram of a display panel provided by an embodiment of the present invention. As Figure 1 shown, the display panel includes a display area AA and a non-display area; the display area AA includes a first through hole K1, a second through hole K2, and a third through hole K3 arranged in a first direction x. The non-display area includes a first non-display area NA1 and a second non-display area NA2. The first non-display area NA1 surrounds the first through hole K1 and the second through hole K2, and the second non-display area NA2 surrounds the third through hole K3. The first non-display area NA1 and the second non-display area NA2 are not connected, indicating that there is a certain displayable area between the second through hole K2 and the third through hole K3. In the first direction x, the minimum distance d1 between the first through hole K1 and the second through hole K2, and the minimum distance between the second through hole K2 and the third through hole K3 is d2, and d1 < d2. Figure 1 The shapes of the through holes in [[ ]] are all schematically shown as circles. In other embodiments, the shapes of the through holes can also be other shapes such as rectangles and ellipses. Since the first non-display area NA1 surrounds two through holes, the lengths of the area jointly occupied by the first non-display area NA1 and the first through hole K1 and the second through hole K2 in the first direction x and the second direction y are different, where the second direction y intersects with the first direction x. As Figure 1As shown, the display area AA has a symmetry axis Z extending in the second direction y. Figure 1 It is schematically shown in Figure 1 that the symmetry axis Z overlaps with the second through hole K2. In some other embodiments, the symmetry axis Z is located between the second through hole K2 and the third through hole K3. In some embodiments, the symmetry axis Z is located in the display area between the second through hole K2 and the third through hole K3. That is to say, the symmetry axis Z is located near the second through hole K2.

[0042] In the display panel provided by the embodiment of the present invention, three through holes arranged in the first direction x are included in the display area AA. The symmetry axis Z of the display area AA in the second direction y is set near the second through hole K2, and the area between the first through hole K1 and the second through hole K2 is set as a non-display area, and d1 < d2, which can make the arrangement of the first through hole K1 and the second through hole K2 relatively compact, thereby reducing the area of the non-display area at the positions where the first through hole K1 and the second through hole K2 are located, and improving the overall symmetry of the displayable area after the through holes are set.

[0043] In the embodiment of the present invention, a non-display area with a certain area is reserved between the first through hole K1 and the second through hole K2, which can be used to centrally arrange some circuit traces. And the first non-display area NA1 and the second non-display area NA2 are not connected, so that there is a display area with a certain area between the second through hole K2 and the third through hole K3. d1 is the minimum distance of the non-display area between the first through hole K1 and the second through hole K2 in the first direction x, and d2 includes the width of the first non-display area NA1 on one side of the second through hole K2, the width of the second non-display area NA2 on one side of the third through hole K3, and the width of the display area between the second through hole K2 and the third through hole K3.

[0044] As Figure 1 shown, the second through hole K2 has a first edge B1 near the third through hole K3, and the third through hole K3 has a second edge B2 near the second through hole K2; in the first direction x, the minimum distance from the first edge B1 to the symmetry axis Z is less than the minimum distance from the second edge B2 to the symmetry axis Z. Such a setting can make the symmetry axis Z located near the second through hole K2, and improve the overall symmetry of the displayable area after the through holes are set.

[0045] In some embodiments, Figure 2 is a schematic diagram of another display panel provided by the embodiment of the present invention. As Figure 2As shown, the display area AA includes a first virtual line X1 and a second virtual line X2 extending along the second direction y. The edge of the first through hole K1 closest to the second through hole K2 in the first direction x intersects the first virtual line X1, and the edge of the second through hole K2 closest to the first through hole K1 in the first direction x intersects the second virtual line X2. The display area AA includes an intermediate area AAZ. The portion of the display area AA between the first virtual line X1 and the second virtual line X2 is the intermediate area AAZ.

[0046] The display area AA includes a first display area AA1, a second display area AA2, and a third display area AA3. In the second direction y, the two first display areas AA1 are respectively located on both sides of the first through hole K1, the two second display areas AA2 are respectively located on both sides of the second through hole K2, and the two third display areas AA3 are respectively located on both sides of the third through hole K3. The first virtual line X1 is the virtual boundary between the first display area AA1 and the intermediate area AAZ, and the second virtual line X2 is the virtual boundary between the second display area AA2 and the intermediate area AAZ.

[0047] The display panel includes a first signal line 12, a second signal line 13, and a third signal line 14 extending along the second direction y. At least part of the first signal line 12 is located in the first display area AA1, at least part of the second signal line 13 is located in the second display area AA2, and the third signal line 14 is located in the third display area AA3. Among them,

[0048] The display panel includes a first winding 41, a second winding 42, and a third winding 43. The first signal lines 12 located on both sides of the first through hole K1 are connected by the first winding 41, the second signal lines 13 located on both sides of the second through hole K2 are connected by the second winding 42, and the third signal lines 14 located on both sides of the third through hole K3 are connected by the third winding 43.

[0049] As Figure 2 shown, the first winding 41 and the second winding 42 are located in the first non-display area NA1, and the third winding 43 is located in the second non-display area NA2. In the first non-display area NA1, the first winding 41 extends along the edge of the first through hole K1, and the second winding 42 extends along the edge of the second through hole K2. In the second non-display area NA2, the third winding 43 extends along the edge of the third through hole K3.

[0050] In this embodiment, in the second direction y, the first display area AA1 corresponds to the first through hole K1, the second display area AA2 corresponds to the second through hole K2, and the third display area AA3 corresponds to the third through hole K3. Then, in the second direction y, the first signal line 12 corresponds to the first through hole K1, the second signal line 13 corresponds to the second through hole K2, and the third signal line 14 corresponds to the third through hole K3. The first winding 41, the second winding 42, and the third winding 43 are respectively wound in the non-display area around the through holes, so that the connection modes of the signal lines truncated due to the arrangement of the through holes in the first display area AA1, the second display area AA2, and the third display area AA3 are the same, which can reduce the brightness difference between the first display area AA1, the second display area AA2, and the third display area AA3, and avoid the display split screen phenomenon on both sides of the symmetry axis Z.

[0051] In other embodiments, Figure 3 Another schematic diagram of the display panel provided by the embodiment of the present invention is shown in Figure 3 As shown, the first winding 41, the second winding 42, and the third winding 43 are all located in the display area AA. Among them, the first winding 41 is wound on the side of the first through hole K1 away from the second through hole K2, the second winding 42 is wound in the display area AA between the second through hole K2 and the third through hole K3, a part of the third winding 43 is wound in the display area AA between the second through hole K2 and the third through hole K3, and a part of the third winding 43 is wound in the display area AA on the side of the third through hole K3 away from the second through hole K2. In this embodiment, the windings connecting the two signal lines on both sides of the through hole are all arranged in the display area AA, which can reduce the frame width of the non-display area around each through hole. Moreover, the connection modes of the signal lines truncated due to the arrangement of the through holes in the first display area AA1, the second display area AA2, and the third display area AA3 are the same, which can reduce the brightness difference between the first display area AA1, the second display area AA2, and the third display area AA3, and avoid the display split screen phenomenon on both sides of the symmetry axis Z.

[0052] Adopting the solution of the embodiment of the present invention, the connection modes of the signal lines truncated due to the arrangement of the through holes in the first display area AA1, the second display area AA2, and the third display area AA3 are the same, which can reduce the brightness difference between the first display area AA1, the second display area AA2, and the third display area AA3. The inventor considered that there is also an intermediate area AAZ between the first display area AA1 and the second display area AA2. If there is a display difference between the intermediate area AAZ and the first display area AA1 and the second display area AA2, it will cause intermediate stripes (generated by the display of the intermediate area AAZ) in the display area AA, resulting in display split screen. Therefore, how to connect the signal lines disconnected in the intermediate area AAZ is also a technical problem that needs to be solved.

[0053] In some embodiments, asFigure 2 As shown, the display panel includes a fourth signal line 11 extending along the second direction y, and the fourth signal line 11 is located in the middle area AAZ. The display panel includes a connection line 20, and the connection line 20 includes a first connection line 21. The two ends of the first connection line 21 are respectively connected to a fourth signal line 11 in the middle area AAZ on both sides of the first non-display area NA1. Among them, the first connection line 21 is located between the first through hole K1 and the second through hole K2. In this embodiment, the connection method of the signal line truncated due to the setting of the through hole in the middle area AAZ is designed, and the fourth signal lines 11 in the middle area AAZ on both sides of the first non-display area NA1 are connected by the first connection line 21. The connection method of the fourth signal lines 11 in the middle area AAZ on both sides of the first non-display area NA1 will not affect the connection method of the signal lines in the display area AA corresponding to each through hole, and can make the connection methods of the signal lines truncated due to the setting of the through hole in the first display area AA1, the second display area AA2, and the third display area AA3 corresponding to the three through holes the same, which can reduce the brightness difference between the first display area AA1, the second display area AA2, and the third display area AA3, and avoid the display split screen phenomenon on both sides of the symmetry axis Z. Optionally, the connection method of the fourth signal lines 11 in the two middle areas AAZ is the same as the connection method of the first and second signal lines, which can improve the brightness difference between the middle area AAZ and the first display area AA1 and the second display area AA2, and improve the display of the middle stripe phenomenon.

[0054] Since the area between the first through hole K1 and the second through hole K2 is a non-display area, the fourth signal line 11 in the middle area AAZ defined by the first virtual straight line X1 and the second virtual straight line X2 will also be truncated by the first non-display area NA1. In the embodiment of the present invention, the fourth signal line 11 is set to be connected by the first connection line 21 located between the two through holes, ensuring the electrical connection between the two fourth signal lines 11 driving the same column of pixel circuits. The first connection line 21 is routed in the non-display area between the first through hole K1 and the second through hole K2, which can make reasonable use of the non-display area between the two through holes. The first through hole K1 and the second through hole K2 are independent of each other and not connected to each other, so some circuit traces can be centrally arranged in the area between the first through hole K1 and the second through hole K2 without affecting the display effect.

[0055] In some embodiments, as Figure 2 shown, a partial line segment of the first connection line 21 located between the first through hole K1 and the second through hole K2 does not extend along the edge of the first through hole K1 or the second through hole K2. In this way, a certain space can be reserved between the first connection line 21 and the through hole, so as to facilitate the design of other wirings.

[0056] In addition, in the embodiment of the present invention, structures such as partition columns or crack detection lines are further provided in the first non-display area NA1 between the first through hole K1 and the second through hole K2.

[0057] In the actual product, multiple fourth signal lines 11 are provided in the intermediate area AAZ, such as ten or dozens of fourth signal lines 11. In the embodiment of the present invention, in order to clearly illustrate the implementation manner of the electrical connection between two fourth signal lines 11 located on both sides of the first non-display area NA1, Figure 2 only two fourth signal lines 11 provided in one intermediate area AAZ are schematically shown. In the following embodiments, the number of fourth signal lines 11 provided in the intermediate area AAZ is also only schematically shown and does not limit the present invention.

[0058] In some other embodiments, as Figure 3 shown, the connection line 20 includes a second connection line 22, and the second connection line 22 connects the fourth signal lines 11 located on both sides of the first non-display area NA1. Among them, at least part of the second connection line 22 is located in the display area AA. Figure 3 It is schematically shown that the second connection line 22 is entirely located in the display area AA. The implementation manner in which part of the line segment of the second connection line 22 is located in the display area AA and part of the line segment is located in the non-display area will be described in the following embodiments. In this implementation manner, the fourth signal lines 11 located on both sides of the first non-display area NA1 are connected by the second connection line 22, and at least part of the second connection line 22 is arranged in the display area AA. The second connection line 22 does not occupy the space of the first non-display area NA1 around the first through hole K1 and the second through hole K2, ensuring the electrical connection between the two fourth signal lines 11 for driving the same column of pixel circuits, and can reduce the area occupied by the first non-display area NA1, the first through hole K1, and the second through hole K2 together, improving the display visual effect. Moreover, the connection manner of the fourth signal lines 11 in the intermediate areas NAZ on both sides of the first non-display area NA1 will not affect the connection manner of the signal lines in the display area AA corresponding to each through hole, enabling the connection manners of the signal lines truncated due to the setting of the through holes in the first display area AA1, the second display area AA2, and the third display area AA3 corresponding to the three through holes to be the same, reducing the brightness difference between the first display area AA1, the second display area AA2, and the third display area AA3, and avoiding the display split screen phenomenon on both sides of the symmetry axis Z. Optionally, the connection manner of the fourth signal lines 11 in the two intermediate areas AAZ is the same as the connection manner of the first and second signal lines, which can improve the brightness difference between the intermediate area AAZ and the first display area AA1 and the second display area AA2, and improve the display of the intermediate stripe phenomenon.

[0059] Figure 2In the embodiment, it is shown that the fourth signal lines 11 in the middle area AAZ on both sides of the first non-display area NA1 are connected by the first connection line 21. The first winding 41 and the second winding 42 are located in the first non-display area NA1, and the third winding 43 is located in the second non-display area NA2. In another embodiment, the fourth signal lines 11 in the middle area AAZ on both sides of the first non-display area NA1 are connected by the first connection line 21, and the first winding 41, the second winding 42, and the third winding 43 are all located in the display area AA.

[0060] Figure 3 In the embodiment, it is shown that the fourth signal lines 11 in the middle area AAZ on both sides of the first non-display area NA1 are connected by the second connection line 22, and the first winding 41, the second winding 42, and the third winding 43 are all located in the display area AA. In another embodiment, the fourth signal lines 11 in the middle area AAZ on both sides of the first non-display area NA1 are connected by the second connection line 22, the first winding 41 and the second winding 42 are located in the first non-display area NA1, and the third winding 43 is located in the second non-display area NA2.

[0061] In some other embodiments, the connection line 20 in the display panel simultaneously includes the first connection line 21 and the second connection line 22. Part of the fourth signal lines 11 on both sides of the first non-display area NA1 are electrically connected by the first connection line 21, and part of the fourth signal lines 11 on both sides of the first non-display area NA1 are electrically connected by the second connection line 22, which is not shown in the drawings here.

[0062] In some embodiments, Figure 4 is another partial schematic diagram of the display panel provided by the embodiment of the present invention. As Figure 4 shown, in the first direction x, the width of the second non-display area NA2 on one side of the third through hole K3 is d3, the width of the first non-display area NA1 on the side of the first through hole K1 far from the second through hole K2 is d4, and the width of the first non-display area NA1 on the side of the second through hole K2 close to the third through hole K3 is d5, where d3 > d4 and d3 > d5. In other words, the frame width around the third through hole K3 is greater than the frame width outside the first through hole K1, and the frame width around the third through hole K3 is greater than the frame width outside the second through hole K2. Such a setting can set relatively more circuit wirings in the second non-display area NA2 to meet the design requirements.

[0063] The display panel not only includes Figure 4 the longitudinal signal lines 10 extending along the second direction y as shown in Figure 4(not shown), and the horizontal signal lines are also truncated by the first non-display area NA1 and the second non-display area NA2. In order to ensure the electrical connection between the truncated horizontal signal lines, winding lines are provided in the non-display area in some embodiments. Since the first non-display area NA1 surrounds the first through hole K1 and the second through hole K2, the length of the area occupied by the first non-display area NA1 and the two through holes in the first direction x is greater than the length of the area occupied by the second non-display area NA2 and the third through hole K3 in the first direction x. Preferably, the winding lines for realizing the electrical connection between the horizontal signal lines are provided in the second non-display area NA2. In this way, the length of the winding lines is short, so the area occupied by the winding lines is also smaller, and thus the frame width of the second non-display area NA2 is larger. The solution for how to electrically connect the horizontal signal lines truncated by the through holes will also be illustrated by examples in the following embodiments.

[0064] In some embodiments, such as Figure 4 shown, the aperture of the third through hole K3 is smaller than the aperture of the first through hole K1, and the aperture of the third through hole K2 is smaller than the aperture of the second through hole K2, and the apertures of the first through hole K1 and the second through hole K2 may be the same or different. Among them, the length of the area jointly occupied by the first non-display area NA1 and the two through holes in the second direction y is d6, and the length of the area jointly occupied by the second non-display area NA2 and the third through hole K3 in the second direction y is d7. In order to realize the electrical connection between the horizontal signal lines truncated by the through holes and minimize the length and occupied area of the winding lines, the winding lines are provided in the second non-display area NA2. In this embodiment, setting the aperture of the third through hole K3 to be the smallest is beneficial to reducing the gap between d6 and d7, and even realizing d6 = d7, so as to improve the display visual effect.

[0065] In some embodiments, Figure 5 Another partial schematic diagram of the display panel provided by the embodiment of the present invention, such as Figure 5As shown, the first connection line 21 includes adjacent first sub-connection lines 211 and second sub-connection lines 212, and the fourth signal line 11 includes adjacent first sub-signal lines 111 and second sub-signal lines 112. The first sub-signal line 111 is electrically connected to the first sub-connection line 211, and the second sub-signal line 112 is electrically connected to the second sub-connection line 212. The first sub-connection line 211 includes a first sub-segment 211a, and the second sub-connection line 212 includes a second sub-segment 212b. The first sub-segment 211a and the second sub-segment 212b are adjacent. In the first direction x, the distance between the first sub-signal line 111 and the second sub-signal line 112 is d8, and the distance between the first sub-segment 211a and the second sub-segment 212b is d9, where d8 is greater than d9. With the design of this embodiment, the distance between two adjacent first connection lines 21 in the first non-display area NA1 can be reduced, thereby reducing the total width occupied by the first connection line 21 in the first direction x. On the one hand, it is beneficial to reduce the size of the distance d1 between the first through hole K1 and the second through hole K2. On the other hand, more space can also be reserved between the first connection line 21 and the first through hole K1, or between the first connection line 21 and the second through hole K2, so as to facilitate wiring in the first non-display area NA1.

[0066] In some embodiments, Figure 6 Another partial schematic diagram of the display panel provided by the embodiment of the present invention Figure 7 is Figure 6 a cross-sectional schematic diagram at the position of the tangent line A-A' in Figure 6 As shown, the first connection line 21 includes a third sub-connection line 213 and a fourth sub-connection line 214. The fourth signal line 11 includes a third sub-signal line 113 and a fourth sub-signal line 114. The third sub-signal line 113 is electrically connected to the third sub-connection line 213, and the fourth sub-signal line 114 is electrically connected to the fourth sub-connection line 214. Combining Figure 7 it can be seen that the display panel includes a substrate 01. The third sub-connection line 213 and the fourth sub-connection line 214 are located in different film layers above the substrate 01, and an insulating layer is provided between the film layer where the third sub-connection line 213 is located and the film layer where the fourth sub-connection line 214 is located. Such a setting can reduce the distance between adjacent first connection lines 21 in the first direction x, thereby reducing the total width occupied by the first connection line 21 between the first through hole K1 and the second through hole K2. On the one hand, it is beneficial to reduce the size of the distance d1 between the first through hole K1 and the second through hole K2. On the other hand, more space can also be reserved between the first connection line 21 and the first through hole K1, or between the first connection line 21 and the second through hole K2, so as to facilitate wiring in the first non-display area NA1.

[0067] Figure 7In the embodiment, it is schematically shown that two metal film layers are used to fabricate the first connection line 21. In some other embodiments, the first connection line 21 includes three sub-connection lines respectively located in three film layers, that is, the first connection line 21 is fabricated using three metal layers, so that the total width occupied by the first connection line 21 between the first through hole K1 and the second through hole K2 can be further reduced.

[0068] In some embodiments, the third sub-connection line 213 and the fourth sub-connection line 214 located in different film layers at least partially overlap, which can also further reduce the total width occupied by the first connection line 21 between the first through hole K1 and the second through hole K2.

[0069] In some other embodiments, the display panel includes a first type of second connection line, and partial line segments of the first type of second connection line are located in the display area and partial line segments are located in the non-display area. Figure 8 Another partial schematic diagram of the display panel provided by the embodiment of the present invention is shown as Figure 8 shown. The non-display area includes a third non-display area NA3, and the third non-display area NA3 is located on the side of the middle area AAZ away from the first non-display area NA1. The second connection line 22 includes a fifth sub-connection line 225, and the fifth sub-connection line 225 includes a first line segment 31 and a second line segment 32 connected to each other; the first line segment 31 is located in the display area AA, and the second line segment 32 is located in the third non-display area NA3. One end of the first line segment 31 is connected to a fourth signal line 11 in one middle area AAZ, and one end of the second line segment 32 is connected to a fourth signal line 11 in another middle area AAZ. In this embodiment, the fifth sub-connection line 225 connects two fourth signal lines 11 located in two middle areas AAZ, and partial line segments of the fifth sub-connection line 225 are located in the third non-display area NA3 and partial line segments are located in the display area AA. The fifth sub-connection line 225 does not occupy the space of the first non-display area NA1 around the first through hole K1 and the second through hole K2, ensuring the electrical connection between the two fourth signal lines 11 for driving the same column of pixel circuits, and moreover, the area occupied by the first non-display area NA1, the first through hole K1 and the second through hole K2 together can be reduced, improving the symmetry of the displayable areas on both sides of the symmetry axis extending in the second direction y.

[0070] Combined with Figure 1 viewed, in the second direction y, the three through holes are located in the upper region of the display panel, and the three through holes are closer to the non-display area in the upper part of the display panel. Figure 8In the embodiment, the third non-display area NA3 is the non-display area that is closer to the three through holes in the second direction y. Such a setting can balance the overall length of the fifth sub-connection line 225 and the length of the first line segment 31 within the display area AA. On the one hand, the total length of the fifth sub-connection line 225 is increased, which can increase the load of the fourth signal line 11 to compensate for the influence of the missing pixels at the position of the first non-display area NA1 on the load of the fourth signal line 11. On the other hand, the length of the first line segment 31 arranged within the display area AA will not be too long, which can reduce the reflection of the first line segment 31 on the ambient light and improve the display effect.

[0071] In some embodiments, such as Figure 8 shown, the shape of the second connection line 22 is approximately a "U"-shaped trace. The second connection line 22 winds around the first non-display area NA1 to electrically connect the two fourth signal lines 11 located on both sides of the first non-display area NA1.

[0072] In some embodiments, Figure 9 Another partial schematic diagram of the display panel provided by the embodiment of the present invention is shown. As Figure 9 shown, the first line segment 31 includes a third sub-line segment 31c extending along the second direction y; at least part of the third sub-line segment 31c is located within the display area AA on the side of the first through hole K1 away from the second through hole K2. In other words, the first line segment 31 in the second connection line 22 winds around within the display area AA on the side of the first through hole K1 away from the second through hole K2, and then is connected to the fourth signal line 11 located within the middle area AAZ. As Figure 9 shown, the first line segment 31 further includes a fourth sub-line segment 31d extending along the first direction x. The fourth sub-line segment 31d is connected to the third sub-line segment 31c, and the fourth sub-line segment 31d is electrically connected to the fourth signal line 11 within the middle area AAZ. This embodiment arranges the first line segment 31 to wind around within the display area AA on the side of the first through hole K1 away from the second through hole K2, which can make the length of the fourth sub-line segment 31d relatively short, and thus can reduce the overall length of the first line segment 31, thereby reducing the reflection of the first line segment 31 on the ambient light.

[0073] In some embodiments, the first line segments 31 in all the second connection lines 22 are wound around within the display area AA on the side of the first through hole K1 away from the second through hole K2, and the first line segments 31 are concentrated in a local position within the display area. Such a setting of the first line segment 31 does not occupy the space of the display area AA on the side of the second through hole K2 away from the first through hole K1, which can improve the freedom of wiring within the display area AA. For example, other functional traces can be set within the display area AA on the side of the second through hole K2 away from the first through hole K1 according to design requirements.

[0074] In some other embodiments, Figure 10Another partial schematic diagram of the display panel provided by the embodiment of the present invention is shown as Figure 10 As shown, the first line segment 31 includes a third sub-line segment 31c extending along the second direction y and a fourth sub-line segment 31d extending along the first direction x. The fourth sub-line segment 31d is connected to the third sub-line segment 31c, and the fourth sub-line segment 31d is electrically connected to the fourth signal line 11 in the intermediate region AAZ. At least a part of the third sub-line segment 31c is located in the display region AA between the second through hole K2 and the third through hole K3. In other words, the first line segment 31 in the second connection line 22 winds around in the display region AA on the side of the second through hole K2 away from the first through hole K1, and then is connected to the fourth signal line 11 located in the intermediate region AAZ. Such an arrangement can make the length of the fourth sub-line segment 31d relatively short, which can also reduce the overall length of the first line segment 31, thereby reducing the reflection of the first line segment 31 on the ambient light.

[0075] In some embodiments, the first line segments 31 in all the second connection lines 22 wind around in the display region AA between the third through hole K3 and the second through hole K2. Compared with the entire display region AA, the area of the display region between the third through hole K3 and the second through hole K2 in the first direction x is relatively small. By centrally arranging the first line segment 31 at a local position between the third through hole K3 and the second through hole K2 for winding, the influence of the reflection of the first line segment 31 on the ambient light on the display effect of the overall display region is relatively small.

[0076] In some other embodiments, Figure 11 Another partial schematic diagram of the display panel provided by the embodiment of the present invention is shown as Figure 11 As shown, the first line segment 31 includes a third sub-line segment 31c extending along the second direction y, and at least a part of the third sub-line segment 31c is located in the display region AA on the side of the third through hole K3 away from the second through hole K2. In this embodiment, the second connection line 22 does not occupy the space of the first non-display region NA1 around the first through hole K1 and the second through hole K2, ensuring the electrical connection between the two fourth signal lines 11 driving the same column of pixel circuits, and can also reduce the area of the region jointly occupied by the first non-display region NA1, the first through hole K1 and the second through hole K2, improving the display visual effect. And with such an arrangement, the total length of the fifth sub-connection line 225 can be increased, thereby increasing the load of the fourth signal line 11, and compensating for the influence of the missing pixels at the position of the first non-display region NA1 on the load of the fourth signal line 11.

[0077] In some embodiments, as Figure 8As shown, the first segment 31 of a part of the second connection line 22 winds around in the display area AA on the side of the first through-hole K1 away from the second through-hole K2, and the first segment 31 of a part of the second connection line 22 winds around in the display area AA on the side of the second through-hole K2 away from the first through-hole K1. In other words, the first segment 31 is arranged to wind around in the display areas AA on both sides of the first non-display area NA1. This implementation can avoid the excessive concentration of the first segment 31, which may lead to an overly large local metal pattern density. After dispersing the first segment 31, the density difference of the metal patterns at different positions in the display area AA can be reduced to a certain extent, thereby reducing the reflectivity difference and improving the display effect. Moreover, the length differences of the second connection lines 22 that wind around in the display areas AA on both sides of the first non-display area NA1 are not significant, resulting in relatively small load differences on each of the fourth signal lines 11, and the display split-screen phenomenon can be improved.

[0078] In some other embodiments, Figure 12 Another partial schematic diagram of the display panel provided by an embodiment of the present invention is shown in Figure 12 As shown, the first segment 31 of a part of the second connection line 22 winds around in the display area AA on the side of the first through-hole K1 away from the second through-hole K2, and the first segment 31 of a part of the second connection line 22 winds around in the display area AA on the side of the third through-hole K3 away from the second through-hole K2.

[0079] In some other embodiments, Figure 13 Another partial schematic diagram of the display panel provided by an embodiment of the present invention is shown in Figure 13 As shown, the first segment 31 of a part of the second connection line 22 winds around in the display area AA on the side of the first through-hole K1 away from the second through-hole K2, the first segment 31 of a part of the second connection line 22 winds around in the display area AA on the side of the second through-hole K2 away from the first through-hole K1, and there is also a part of the first segment 31 of the second connection line 22 that winds around in the display area AA on the side of the third through-hole K3 away from the second through-hole K2.

[0080] In some embodiments, the number of third sub - line segments 31c in the display area AA on the side of the first through - hole K1 away from the second through - hole K2 is m1, and the number of third sub - line segments 31c in the display area AA on the side of the second through - hole K2 away from the first through - hole K1 is m2. Both m1 and m2 are positive integers, and │m1 - m2│≤1. Among them, the third sub - line segments 31c in the display area AA on the side of the second through - hole K2 away from the first through - hole K1 include the third sub - line segments 31c between the second through - hole K2 and the third through - hole K3 and / or the third sub - line segments 31c in the display area AA on the side of the third through - hole K3 away from the second through - hole K2. Setting │m1 - m2│≤1, the difference in the number of the first line segments 31 on both sides of the intermediate area AAZ in the first direction x is not large. After the first line segments 31 are dispersedly arranged, the difference in the metal pattern density at different positions in the display area AA can be reduced to a certain extent, thereby reducing the reflectivity difference and improving the display split - screen phenomenon.

[0081] In some other embodiments, the display panel includes a second type of second connection line, and all the second type of second connection lines are located in the display area. Figure 14 Another partial schematic diagram of the display panel provided by the embodiment of the present invention is as Figure 14 shown. The second connection line 22 includes a sixth sub - connection line 226. The sixth sub - connection line 226 includes a third line segment 33 extending in the first direction x and a fourth line segment 34 extending in the second direction y. Both ends of the fourth line segment 34 are respectively connected to a third line segment 33. Both the third line segment 33 and the fourth line segment 34 are located in the display area AA, and the two third line segments 33 are respectively connected to a fourth signal line 11 located in the intermediate area AAZ. In this embodiment, the sixth sub - connection line 226 is arranged in the display area AA. By connecting the two fourth signal lines 11 on both sides of the first non - display area NA1 through the sixth sub - connection line 226, the sixth sub - connection line 226 does not occupy the space of the first non - display area NA1 around the first through - hole K1 and the second through - hole K2, ensuring the electrical connection between the two fourth signal lines 11 for driving the same column of pixel circuits, and can reduce the area occupied by the first non - display area NA1, the first through - hole K1 and the second through - hole K2 together, and improve the symmetry of the displayable areas on both sides of the symmetry axis extending in the second direction y.

[0082] As Figure 14 shown, at least a part of the fourth line segment 34 of the sixth sub - connection line 226 is located in the display area AA on the side of the first through - hole K1 away from the second through - hole K2. In this embodiment, the sixth sub - connection line 226 is wound in the display area AA on the side of the first through - hole K1 away from the second through - hole K2, which can make the total length of the sixth sub - connection line 226 relatively short, thereby reducing the reflection of the sixth sub - connection line 226 on the ambient light.

[0083] In some embodiments, all the sixth sub-connection lines 226 are wound within the display area AA on the side of the first through-hole K1 away from the second through-hole K2, and the sixth sub-connection lines 226 are centrally arranged within the display area at a local position. With such an arrangement, the sixth sub-connection lines 226 do not occupy the space of the display area AA on the side of the second through-hole K2 away from the first through-hole K1, which can improve the freedom of wiring within the display area AA. For example, other functional traces can be arranged within the display area AA on the side of the second through-hole K2 away from the first through-hole K1 according to design requirements.

[0084] In some other embodiments, Figure 15 Another partial schematic diagram of a display panel provided by an embodiment of the present invention is shown in Figure 15 As shown, at least a fourth segment 34 of some of the sixth sub-connection lines 226 is located within the display area AA between the second through-hole K2 and the third through-hole K3. In this embodiment, the sixth sub-connection lines 226 are wound within the display area AA between the third through-hole K3 and the second through-hole K2, which can make the total length of the sixth sub-connection lines 226 relatively short, thereby reducing the reflection of the sixth sub-connection lines 226 on ambient light. Compared with the entire display area AA, the area of the display region between the third through-hole K3 and the second through-hole K2 in the first direction x is smaller. By centrally arranging the sixth sub-connection lines 226 to wind at a local position between the third through-hole K3 and the second through-hole K2, the influence of the reflection of the sixth sub-connection lines 226 on ambient light on the display effect of the overall display region is relatively small.

[0085] In some embodiments, all the sixth sub-connection lines 226 are wound within the display area AA between the third through-hole K3 and the second through-hole K2.

[0086] In some other embodiments, Figure 16 Another partial schematic diagram of a display panel provided by an embodiment of the present invention is shown in Figure 16 As shown, at least a fourth segment 34 of some of the sixth sub-connection lines 226 is located within the display area AA on the side of the third through-hole K3 away from the second through-hole K2. In this embodiment, the sixth sub-connection lines 226 are located within the display area AA and do not occupy the space of the first non-display area NA1 around the first through-hole K1 and the second through-hole K2, ensuring the electrical connection between two fourth signal lines 11 for driving the same column of pixel circuits, and can reduce the area of the region jointly occupied by the first non-display area NA1, the first through-hole K1, and the second through-hole K2, improving the display visual effect. Moreover, with such an arrangement, the total length of the sixth sub-connection lines 226 can be increased, thereby increasing the load of the fourth signal lines 11, and compensating for the influence of the missing pixels at the position of the first non-display area NA1 on the load of the fourth signal lines 11.

[0087] In some other embodiments, Figure 17Another partial schematic diagram of the display panel provided by the embodiment of the present invention, as Figure 17 shown, the fourth segment 34 of a part of the sixth sub-connection line 226 is located in the display area AA on the side of the first through hole K1 away from the second through hole K2, and a part of the fourth segment 34 of the sixth sub-connection line 226 is located in the display area AA between the second through hole K2 and the third through hole K3. This implementation mode disperses the sixth sub-connection line 226, which can avoid the excessive local metal pattern density caused by the centralized arrangement of the sixth sub-connection line 226. After the sixth sub-connection line 226 is dispersed, the difference in the metal pattern density at different positions in the display area AA can be reduced to a certain extent, thereby reducing the reflectivity difference and improving the display effect. Moreover, the length differences of the sixth sub-connection lines 226 wound in the display areas AA on both sides of the first non-display area NA1 are not significant, so that the load differences on each fourth signal line 11 are small, and the display split-screen phenomenon can be improved.

[0088] In another implementation mode, the fourth segment 34 of a part of the sixth sub-connection line 226 is located in the display area AA on the side of the first through hole K1 away from the second through hole K2, and the fourth segment 34 of a part of the sixth sub-connection line 226 is located in the display area AA on the side of the third through hole K3 away from the second through hole K2, which is not shown in the figure here.

[0089] In some other implementation modes, Figure 18 Another partial schematic diagram of the display panel provided by the embodiment of the present invention, as Figure 18 shown, the fourth segment 34 of a part of the sixth sub-connection line 226 is located in the display area AA on the side of the first through hole K1 away from the second through hole K2, a part of the fourth segment 34 of the sixth sub-connection line 226 is located in the display area AA between the second through hole K2 and the third through hole K3, and a part of the fourth segment 34 of the sixth sub-connection line 226 is located in the display area AA on the side of the third through hole K3 away from the second through hole K2.

[0090] In some embodiments, the number of the fourth line segments 34 in the display area AA on the side of the first through hole K1 away from the second through hole K2 is m3, and the number of the fourth line segments 34 in the display area AA on the side of the second through hole K2 away from the first through hole K1 is m4, where both m3 and m4 are positive integers, and │m3 - m4│≤1. The fourth line segments 34 in the display area AA on the side of the second through hole K2 away from the first through hole K1 include the fourth line segments 34 between the second through hole K2 and the third through hole K3 and / or the fourth line segments 34 in the display area AA on the side of the third through hole K3 away from the second through hole K2. By setting │m3 - m4│≤1, the difference in the number of the sixth sub-connection lines 226 on both sides of the middle area AAZ in the first direction x is not large. After the sixth sub-connection lines 226 are dispersedly arranged, the difference in the metal pattern density at different positions in the display area AA can be reduced to a certain extent, thereby reducing the reflectivity difference and improving the display effect.

[0091] In some other embodiments, the display panel includes a fifth sub-connection line 225 and a sixth sub-connection line 226. Figure 19 Another partial schematic diagram of the display panel provided by an embodiment of the present invention is shown as Figure 19 shown. The second connection line 22 includes a fifth sub-connection line 225 and a sixth sub-connection line 226. Part of the line segments of the fifth sub-connection line 225 are located in the third non-display area NA3, and part of the line segments are located in the display area AA. The sixth sub-connection line 226 is entirely located in the display area AA. Among them, the number of the fifth sub-connection lines 225 is less than the number of the sixth sub-connection lines 226. In combination with Figure 1 viewing, in the second direction y, the three through holes are located in the upper region of the display panel, and the three through holes are closer to the non-display area in the upper part of the display panel. Figure 19 In the embodiment, the third non-display area NA3 is a non-display area that is relatively close to the three through holes in the second direction y. When the space of the display area AA between the first non-display area NA1 and the third non-display area NA3 is insufficient, the sixth sub-connection lines 226 are arranged in the display area AA between the first non-display area NA1 and the third non-display area NA3, and at the same time, part of the line segments of the fifth sub-connection line 225 are arranged in the third non-display area NA3 to ensure the electrical connection between the fourth signal lines 11 on both sides of the first non-display area NA1. Moreover, since the third non-display area NA3 is relatively close to the three through holes, it can make Figure 20 the length difference between the fifth sub-connection line 225 and the sixth sub-connection line 226 set in the embodiment relatively small, so that the load difference on each fourth signal line 11 is relatively small. In addition, the number of the fifth sub-connection lines 225 is less than the number of the sixth sub-connection lines 226, that is, the fifth sub-connection line 225 is preferentially arranged in the display area AA to reduce the influence of the sixth sub-connection line 226 on the frame width.

[0092] Figure 19 In the embodiment, only the fifth sub-connection line 225 and the sixth sub-connection line 226 are wound on the side of the first through hole K1 away from the second through hole K2 for illustration.

[0093] In an embodiment of the present invention, the second connection line 22 includes a fifth sub-connection line 225 and a sixth sub-connection line 226. Among them, the fifth sub-connection line 225 can be wound on the side of the first through hole K1 away from the second through hole K2, or wound between the third through hole K3 and the second through hole K2, or wound on the side of the third through hole K3 away from the second through hole K2. The sixth sub-connection line 226 can be wound on the side of the first through hole K1 away from the second through hole K2, or wound between the third through hole K3 and the second through hole K2, or wound on the side of the third through hole K3 away from the second through hole K2.

[0094] In some embodiments, Figure 20 Another partial schematic diagram of a display panel provided by an embodiment of the present invention is shown in Figure 20 As shown, the number of the first winding lines 41 on both sides of the first through hole K1 is the same, and / or the number of the second winding lines 42 on both sides of the second through hole K2 is the same. Setting the number of the first winding lines 41 on both sides of the first through hole K1 to be the same can reduce the length difference between different first winding lines 41, and thus can reduce the load difference between the first signal lines 12, improving the brightness uniformity of the first display area AA1. Setting the number of the second winding lines 42 on both sides of the second through hole K2 to be the same can reduce the length difference between different second winding lines 42, and thus can reduce the load difference between the second signal lines 13, improving the brightness uniformity of the second display area AA2.

[0095] In other embodiments, Figure 21 Another partial schematic diagram of a display panel provided by an embodiment of the present invention is shown in Figure 21As shown, the number of the first winding lines 41 on the side of the first through hole K1 far from the second through hole K2 is n1, and the number of the first winding lines 41 on the side of the first through hole K1 close to the second through hole K2 is n2, where n1 < n2; and / or, the number of the second winding lines 42 on the side of the second through hole K2 far from the first through hole K1 is n3, and the number of the second winding lines 42 on the side of the second through hole K2 close to the first through hole K1 is n4, where n3 < n4. In this embodiment, the number of the first winding lines 41 on the side of the first through hole K1 far from the second through hole K2 is set to be small, and the number of the second winding lines 42 on the side of the second through hole K2 far from the first through hole K1 is set to be small. More of the first winding lines 41 and the second winding lines 42 are concentrated between the first through hole K1 and the second through hole K2, which is beneficial to reducing the frame width on the side of the first through hole K1 far from the second through hole K2, and is also beneficial to reducing the frame width on the side of the second through hole K2 far from the first through hole K1, and can improve the display visual effect.

[0096] In some embodiments, both the first winding lines 41 and the second winding lines 42 are located between the first through hole K1 and the second through hole K2. That is to say, no first winding lines 41 are provided on the side of the first through hole K1 far from the second through hole K2, and no second winding lines 42 are provided on the side of the second through hole K2 far from the first through hole K1. Such a setting can greatly reduce the frame width on the side of the first through hole K1 far from the second through hole K2 and the frame width on the side of the second through hole K2 far from the first through hole K1.

[0097] In some embodiments, Figure 22 is Figure 21 a schematic cross-sectional view at the position of the middle tangent B - B′, as Figure 22 shown, the first winding lines 41 include a first sub-winding line 41a and a second sub-winding line 41b, and the first sub-winding line 41a and the second sub-winding line 41b are located in different film layers; the second winding lines 42 include a third sub-winding line 42c and a fourth sub-winding line 42d, and the third sub-winding line 42c and the fourth sub-winding line 42d are located in different film layers. Optionally, the first sub-winding line 41a and the third sub-winding line 42c are located in the same film layer, and the second sub-winding line 41b and the fourth sub-winding line 42d are located in the same film layer. In this embodiment, the first winding lines 41 are made of two metal film layers, and the second winding lines 42 are made of two metal film layers. Such a setting can reduce the pitch between adjacent first winding lines 41 in the first direction x, and can also reduce the pitch between adjacent second winding lines 42 in the first direction x, thereby reducing the total width occupied by the first winding lines 41 between the first through hole K1 and the second through hole K2, reducing the size of the pitch d1 between the first through hole K1 and the second through hole K2, being beneficial to reducing the total length occupied by the region formed by the first non-display area NA1, the first through hole K1, and the second through hole K2 in the first direction x, and can improve the overall display effect.

[0098] In other embodiments, only the first winding 41 of the first winding 41 and the second winding 42 is made of two metal layers, that is, the first winding 41 includes a first sub-winding 41a and a second sub-winding 41b, and the first sub-winding 41a and the second sub-winding 41b are located in different film layers.

[0099] In other embodiments, only the second winding 42 of the first winding 41 and the second winding 42 is made of two metal layers, that is, the second winding 42 includes a third sub-winding 42c and a fourth sub-winding 42d, and the third sub-winding 42c and the fourth sub-winding 42d are located in different film layers.

[0100] In some embodiments, as Figure 20 shown, the number of the third windings 43 located on both sides of the third through hole K3 is the same. Such a setting can reduce the length difference between different third windings 43, and thus can reduce the load difference between the third signal lines 14, improving the brightness uniformity of the third display area AA3. Moreover, it is beneficial to make the frame widths on both sides of the third through hole K3 consistent, improving the aesthetics.

[0101] In some embodiments, multiple third windings 43 are made of two metal film layers, which can reduce the distance between adjacent third windings 43, thereby being beneficial to reducing the frame width of the second non-display area NA2 and improving the overall visual effect.

[0102] In other embodiments, on at least one side of the through hole in the first direction x: at least two of the first winding 41 located on one side of the first through hole K1, the second winding 42 located on one side of the second through hole K2, and the third winding 43 located on one side of the third through hole K3 have different numbers.
