It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here.

[0026] As introduced in the background technology, there is a technical problem in the prior art that the display effect of the display panel is poor. To solve the above technical problem, the embodiments of the present application provide a display panel and a display device.
[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0028] In this embodiment, a display panel is provided. Figure 1 is a schematic top view of a display panel provided according to an embodiment of the present application. Figure 1 As shown, the display panel 10 includes:
[0029] The first wiring area 11;
[0030] A first display area 12 at least half surrounds the first wiring area 11;
[0031] Specifically, the first wiring area 11 may be partially surrounded by the first display area 12 with an opening, that is, not completely closed; the first wiring area 11 may also be surrounded by the first display area, that is, completely closed.
[0032] A plurality of connection data lines 13, each of the connection data lines 13 includes a first portion 14 and a second portion 15 that are electrically connected, the first portion 14 is located in the first routing area 11, and the second portion 15 is located in the first display area 12;
[0033] Specifically, one end of the first portion 14 is electrically connected to one end of the second portion 15 .
[0034] A plurality of pixel column groups 16, located in the first display area 12, the pixel column group 16 includes at least two pixel columns 17, and each of the pixel columns 17 is electrically connected to two of the connection data lines 13;
[0035] Specifically, each of the pixel columns 17 is electrically connected to two different connection data lines 13, that is, the display panel adopts a double data signal line (DDL) method for signal transmission, and the two connection data lines 13 can be located on both sides of the electrically connected pixel columns 17, or on the same side of the electrically connected pixel columns 17.
[0036] The plurality of pixel column groups 16 include adjacent first pixel column groups 161 and second pixel column groups 162, the plurality of connection data lines 13 include first connection data lines 131 corresponding to the first pixel column groups 161 and second connection data lines 132 corresponding to the second pixel column groups 162, wherein the first portion 14 of the first connection data lines 131 and the first portion 14 of the second connection data lines 132 are located in different film layers.
[0037] Specifically, the first pixel column group 161 corresponds to a plurality of first connection data lines 131, and the second pixel column group 162 corresponds to a plurality of second connection data lines 132. The first connection data lines 131 located in the first wiring area 11 and the second connection data lines 132 located in the first wiring area are located in different film layers.
[0038] According to the embodiment, the first display area in the display panel at least half surrounds the first wiring area, and the first display area is provided with a plurality of pixel column groups, each pixel column group includes at least two pixel columns, each pixel column corresponds to two electrically connected data lines, and the signal is transmitted by DDL, the first part of each connecting data line is located in the first wiring area, the second part is located in the first display area, and the first part of the connecting data line corresponding to the adjacent pixel column groups is located in different film layers. Since the wiring space of the first wiring area is small, the connecting data lines are prone to signal crosstalk in the first wiring area. In the present application, the first part of the connecting data line corresponding to the adjacent pixel column groups is set in different film layers, so that the adjacent connecting data lines in the same film layer correspond to the pixel column groups in alternate columns, and the connecting data lines of the pixel column groups in alternate columns will not overlap in time sequence when charging, thereby avoiding the signal crosstalk problem of the connecting data lines corresponding to the adjacent pixel column groups, realizing high-quality and stable transmission of signals, and ensuring a good display effect of the display panel. Furthermore, compared to setting multiple first parts corresponding to adjacent pixel column groups on the same film layer, the wiring spacing of the first part on each film layer in the present application does not need to consider the crosstalk problem, so that the spacing between adjacent first parts can be smaller, thereby ensuring that the wiring area occupied by the first part in the first routing area is smaller.
[0039] Wherein, one pixel column 17 is composed of a plurality of pixels arranged at intervals along a first direction, and one pixel column group 16 is composed of a plurality of pixel units arranged at intervals along the first direction, and a pixel unit includes a plurality of pixels. The first direction is the extension direction of the pixel column, also called the column direction.
[0040] In an optional solution, in the thickness direction of the display panel, the first portion 14 of the first connection data line 131 overlaps with the first portion 14 of the second connection data line 132. Since the first portion of the first connection data line and the first portion of the second connection data line are located in different film layers, the first portions of the two are arranged to overlap in the thickness direction, thereby eliminating signal crosstalk and ensuring that the wiring area of the multiple connection data lines in the first routing area is small.
[0041] Since there are multiple first connection data lines 131 in the first pixel column group and multiple second connection data lines 132 in the second pixel column group, the overlapping manner of the first parts 14 of the multiple first connection data lines 131 and the first parts 14 of the multiple second connection data lines 132 can be any feasible manner, for example, the first parts of the first connection data lines 131 overlap with the first parts of the second connection data lines 132 in a one-to-one correspondence, or for example, the first part of one first connection data line 131 overlaps with the first parts of multiple second connection data lines 132.
[0042] In some exemplary embodiments of the present application, Figure 2 As shown, the pixel column located at a predetermined position in the first pixel column group is a first target pixel column, the pixel column located at the predetermined position in the second pixel column group is a second target pixel column, the first portions 14 of the two first connection data lines electrically connected to the first target pixel column are a first target portion 141, the first portions 14 of the two second connection data lines electrically connected to the second target pixel column are a second target portion 142, and in the thickness direction of the display panel, at least one of the two first target portions 141 overlaps with at least one of the two second target portions 142. In this embodiment, in two adjacent pixel column groups, the two connection data lines connected to the pixel columns at corresponding positions overlap with each other in the first routing area, so that the wiring of the first portion on different film layers is basically the same, which is conducive to simplifying the wiring design and manufacturing process.
[0043] In the embodiment, the first target pixel column and the second target pixel column are located at corresponding positions in the adjacent pixel column group; for example, when the first target pixel column is the first pixel column in the first pixel column group, the second target pixel column is the first pixel column in the second pixel column group. One of the first target portions may overlap with one of the two second target portions, or may overlap with both of the two second target portions; another of the first target portions may overlap with one of the two second target portions, or may overlap with both of the two second target portions.
[0044] In order to further reduce the wiring area occupied by the connecting data line in the first wiring area and further simplify the design of the connecting data line in the first wiring area, in the present application, Figure 3 As shown, in the thickness direction of the display panel, the first target portion 141 and the second target portion 142 overlap in a one-to-one correspondence.
[0045] In the embodiment, the relative position relationship between the two first connection data lines and the first target pixel column, and the relative position relationship between the two second connection data lines and the second target pixel column are the same. For example, the two first connection data lines are distributed on both sides of the first target pixel column, the two second connection data lines are distributed on both sides of the second target pixel column, the first part of the first connection data line located on the first side of the first target pixel column overlaps with the first part of the second connection data line located on the first side of the second target pixel column, and the first part of the first connection data line located on the second side of the first target pixel column overlaps with the first part of the second connection data line located on the second side of the second target pixel column. For another example, two first connection data lines are distributed on the same side of the first target pixel column, one first connection data line is closer to the first target pixel column than the other first connection data line, two second connection data lines are distributed on the same side of the second target pixel column, one second connection data line is closer to the second target pixel column than the other second connection data line, a first portion of the first connection data line closer to the first target pixel column overlaps with a first portion of the second connection data line closer to the second target pixel column, and a first portion of the first connection data line away from the first target pixel column overlaps with a first portion of the second connection data line away from the second target pixel column.
[0046] In actual application, the display panel has multiple first pixel column groups and multiple second pixel column groups respectively. Those skilled in the art can set multiple film layers and allocate the film layers where the first parts of the first connection data lines and the second connection data lines are located to solve the signal crosstalk problem.
[0047] In order to take into account both the display effect of the display panel and the thin and light design requirements, another optional solution is as follows: Figure 4As shown, there are a plurality of first pixel column groups and a plurality of second pixel column groups, a plurality of the first pixel column groups are located in odd columns, and a plurality of the second pixel column groups are located in even columns, that is, the first pixel column groups and the second pixel column groups are arranged alternately, the first portions of all the first connection data lines 131 are located in the same film layer, and the first portions of all the second connection data lines 132 are located in the same film layer. In other words, the first portions of all the connection data lines occupy two film layers, which can further solve the signal crosstalk problem of the connection data lines corresponding to the adjacent pixel column groups, so that the display effect of the display panel is better, and can ensure that the first portions of the connection data lines occupy fewer film layers, thereby realizing a light and thin design of the display panel.
[0048] In the present application, the first connection data lines and the second connection data lines may be arranged to overlap in alternate columns, thereby saving layout and wiring space and reducing signal line crosstalk.
[0049] Specifically, Figure 4 As shown, the display panel further includes: a first metal film layer 18, wherein the first portion 14 of each first connection data line 131 is located in the first metal film layer 18; an interlayer insulating layer 19, which is located on the first metal film layer 18; and a second metal film layer 20, which is located on a side of the interlayer insulating layer 19 away from the first metal film layer 18, wherein the first portion 14 of each second connection data line 132 is located in the second metal film layer 20. In the embodiment, the first portion of the first connection data line is disposed in the first metal film layer, and the first portion of the second connection data line is disposed in the second metal film layer, and the two metal film layers are isolated and insulated by the interlayer insulating layer.
[0050] In addition to the interlayer insulating layer, other structural layers may be provided between the first metal film layer and the second metal film layer. A person skilled in the art may select two metal film layers that are far apart as the first metal film layer and the second metal film layer, so as to minimize the coupling between the connecting signal lines in the two film layers.
[0051] According to other exemplary embodiments of the present application, Figure 5As shown, the display panel further includes: a hole structure 21, the first wiring area 11 at least half surrounds the hole structure 21; a plurality of scan lines 22, the plurality of scan lines 22 are arranged at intervals along the first direction and extend along the second direction, the scan lines 22 extend from the first display area 12 to the hole structure 21 along the second direction, bypass the hole structure 21 and extend from the first wiring area 11 to the first display area 12 along the second direction, and the first direction intersects with the second direction. In this embodiment, the display panel is a display panel with holes, and the scan lines bypass the hole structure in the second direction and extend to both sides of the hole structure to ensure the continuity of the scan signal on both sides of the hole structure.
[0052] According to some further exemplary embodiments of the present application, Figure 6 As shown, the display panel further includes: a hole structure 21, the first wiring area 11 at least half surrounds the hole structure 21; a plurality of scan lines 22, the scan line 22 includes a first sub-scan line 221 and a second sub-scan line 222, the first sub-scan line 221 extends from the first display area 12 to the first side of the hole structure 21 along the second direction, the second sub-scan line 222 extends from the second side of the hole structure 21 to the first display area 12 along the second direction, the first side and the second side are two opposite sides of the hole structure in the second direction. In this embodiment, the display panel is a display panel with holes, a scan line includes two sub-scan lines, and sub-scan lines are respectively arranged on both sides of the hole structure to extend to the first display area, so that the number of windings in the first wiring area can be reduced, thereby avoiding the problem of a large border in the first wiring area, and the difference in the load of the scan signal line in the area with the hole structure and the area without the hole structure can also be reduced.
[0053] Specifically, in the same row period, the data signal input times of any two adjacent first connection data lines do not overlap, and the data signal input times of any two adjacent second connection data lines do not overlap. In this embodiment, the two adjacent first connection data lines located in the same film layer belong to alternate column data signal lines, and the two adjacent second connection data lines located in the same film layer belong to alternate column data signal lines, and there will be no timing overlap, so the signal crosstalk problem between adjacent connection data lines can be further solved, and the display effect of the display panel can be further guaranteed to be better.
[0054] In a specific application process, the hole structure may be a blind hole structure or a through hole structure, and various electronic components, such as a camera or a watch pointer, may be placed in the hole structure.
[0055] In a specific embodiment, there is one hole structure, and the outer diameter of the hole structure is greater than or equal to 4 mm. In this embodiment, the display panel has one hole structure, but the size of the hole structure is large, so that the space used for wiring in the first wiring area is small, and the crosstalk between the connection signal lines in the first wiring area is more serious. In this case, the design of setting the first part of the connection data line corresponding to the adjacent pixel column group in different film layers by the present application can avoid the crosstalk problem between the connection data lines with overlapping timing, and at the same time, it can ensure that the spacing between adjacent connection data lines is large in a limited wiring space, thereby further avoiding the display split screen phenomenon caused by signal crosstalk.
[0056] In another specific embodiment, there are multiple hole structures, each of which has a diameter less than 4 mm, and the multiple hole structures are arranged at intervals. In this embodiment, although the size of the hole structure of the display panel is not large, there are multiple hole structures, which makes the space for wiring in the first wiring area small, and the crosstalk between the connection signal lines in the first wiring area is more serious. In this case, the design of setting the first part of the connection data line corresponding to the adjacent pixel column group in different film layers by the present application can avoid the crosstalk problem between the connection data lines with overlapping timing, and at the same time, it can ensure that the spacing between adjacent connection data lines is large in a limited wiring space, thereby further avoiding the display split screen phenomenon caused by signal crosstalk.
[0057] In addition, the first wiring area also includes an edge area surrounding the hole structure, and the width of the edge area is less than or equal to 0.6 mm. The width of the edge area is small, and the crosstalk between the connection signal lines therein is more serious. In this case, the design of setting the first part of the connection data lines corresponding to the adjacent pixel column groups in different film layers by the present application can avoid the crosstalk problem between the connection data lines with overlapping timing, and at the same time, it can ensure that the spacing between adjacent connection data lines is large in a limited wiring space, thereby further avoiding the display split screen phenomenon caused by signal crosstalk.
[0058] The hole structure may be located in the middle of the display panel or at the edge of the display panel.
[0059] Optionally, the second parts of the plurality of connection data lines are located in the same film layer. Since the wiring space of the first display area is large, the connection data lines can be arranged at larger intervals in the first display area, and the crosstalk between the connection data lines is small, so the second parts of the plurality of connection data lines can be arranged in the same film layer.
[0060] Of course, in addition to the above arrangement, in other exemplary embodiments, the second portion of the first connection data line and the second portion of the second connection data line may be located in different film layers. The second portions of the connection data lines corresponding to adjacent pixel column groups with overlapping timing are arranged in different film layers, which can further solve the problem of signal crosstalk between the connection data lines corresponding to adjacent pixel column groups, and further ensure a better display effect of the display panel.
[0061] In the case where the second portion of the first connecting data line and the second portion of the second connecting data line are located in different film layers, the relative position relationship setting of the second portion of the first connecting data line and the second portion of the second connecting data line in different film layers can refer to the setting of the first portion, and this application will not repeat them here.
[0062] In some embodiments, Figure 1 As shown, the display panel 10 further includes: a second display area 26 , and the second display area 26 is located on at least one side of the first display area 12 along the arrangement direction of the connection data lines 13 .
[0063] The display panel further includes: a plurality of third connection data lines, located in the second display area, the plurality of third connection data lines are arranged at intervals along the second direction, and each of the third connection data lines extends along the first direction; a plurality of third pixel column groups, located in the second display area, each of the third pixel column groups includes at least two third pixel columns, and each of the third pixel columns is electrically connected to two third connection data lines. The plurality of third connection data lines corresponding to two adjacent third pixel column groups may be located in the same film layer.
[0064] Figure 1 The embodiment in which the first display area 12 is located at the upper and lower sides of the first wiring area 11 and the second display area 26 is located at the left and right sides of the first display area 12 is exemplarily shown. In actual application, the positions of the first display area 12 and the second display area 26 are not limited to Figure 1 As shown, for example, the first display area 12 may be located only below the first wiring area 11 ; for another example, the second display area 26 may be located only on the left or right side of the first display area 12 .
[0065] As an alternative, Figure 1 As shown, the display panel further includes: a non-display area 23, at least located on one side of the first display area 12; a multiplexer 24, located in the non-display area 23, and one end of each second part 15 is electrically connected to the multiplexer 24. By setting the multiplexer to realize multiplexing of the communication channel, the capacity of the communication channel can be fully utilized, the system cost can be reduced, and the efficiency and reliability of signal transmission can be improved.
[0066] Exemplarily, the multiplexer is a 1:n multiplexer, where n≥4.
[0067] In addition, the display panel further comprises: a shift register, which is located in the non-display area and is electrically connected to the plurality of scan lines. The shift register is used to realize the row-by-row scanning driving function of the display panel.
[0068] Figure 7 The schematic diagram of the structure of two adjacent pixel column groups of a display panel using a 1:4 multiplexer is shown as an example. Figure 7 As shown, the display panel includes an adjacent first pixel column group and a second pixel column group, each of the first pixel column group and the second pixel column group includes four pixel columns, and the first connection data line 131 corresponding to the first pixel column group and the second connection data line 132 corresponding to the second pixel column group are electrically connected to the same 1:4 multiplexer 24.
[0069] The present application also provides a display device 25, such as Figure 8 As shown, the display device 25 includes: any one of the display panels 10 described above.
[0070] In the display device, the first display area of the display panel at least half surrounds the first wiring area, and the first display area is provided with a plurality of pixel column groups, each pixel column group includes at least two pixel columns, each pixel column corresponds to two electrically connected data lines, and signals are transmitted by DDL, the first part of each connecting data line is located in the first wiring area, the second part is located in the first display area, and the first parts of the connecting data lines corresponding to adjacent pixel column groups are located in different film layers. Since the signals transmitted by the connecting data lines corresponding to adjacent pixel column groups overlap in timing, and the wiring space of the first wiring area is small, the connecting data lines are prone to signal crosstalk in the first wiring area. The display panel of the present application sets the first parts of the connecting data lines corresponding to adjacent pixel column groups in different film layers, avoiding the signal crosstalk problem of the connecting data lines corresponding to adjacent pixel column groups, achieving high-quality and stable transmission of signals, and ensuring a good display effect of the display device. Furthermore, compared to setting multiple first parts corresponding to adjacent pixel column groups on the same film layer, the wiring spacing of the first part on each film layer in the present application does not need to consider the crosstalk problem, so that the spacing between adjacent first parts can be smaller, thereby ensuring that the wiring area occupied by the first part in the first routing area is smaller, which is conducive to the miniaturized design of the display device.
[0071] like Figure 8 As shown, the display panel is a display panel having a hole structure 21 .
[0072] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.
[0073] From the above description, it can be seen that the embodiments described in this application achieve the following technical effects:
[0074] 1) In the display panel of the present application, the first display area at least half surrounds the first wiring area. The first display area is provided with a plurality of pixel column groups, each pixel column group includes at least two pixel columns, each pixel column corresponds to two electrically connected data lines, and signals are transmitted by DDL. The first part of each connecting data line is located in the first wiring area, and the second part is located in the first display area. The first parts of the connecting data lines corresponding to adjacent pixel column groups are located in different film layers. Since the wiring space of the first wiring area is small, the connecting data lines are prone to signal crosstalk in the first wiring area. The present application sets the first parts of the connecting data lines corresponding to adjacent pixel column groups in different film layers, so that the adjacent connecting data lines in the same film layer correspond to the pixel column groups in alternate columns, and the connecting data lines of the pixel column groups in alternate columns will not overlap in timing when charging, thereby avoiding the signal crosstalk problem of the connecting data lines corresponding to the adjacent pixel column groups, achieving high-quality and stable signal transmission, and ensuring a good display effect of the display panel. Furthermore, compared to setting multiple first parts corresponding to adjacent pixel column groups on the same film layer, the wiring spacing of the first part on each film layer in the present application does not need to consider the crosstalk problem, so that the spacing between adjacent first parts can be smaller, thereby ensuring that the wiring area occupied by the first part in the first routing area is smaller.
[0075] 2) In the display device of the present application, the first display area of the display panel at least half surrounds the first wiring area. The first display area is provided with a plurality of pixel column groups, each pixel column group includes at least two pixel columns, each pixel column corresponds to two electrically connected data lines, and signals are transmitted by DDL. The first part of each connecting data line is located in the first wiring area, and the second part is located in the first display area. The first parts of the connecting data lines corresponding to adjacent pixel column groups are located in different film layers. Since the wiring space of the first wiring area is relatively small, the connecting data lines are prone to signal crosstalk in the first wiring area. The present application sets the first parts of the connecting data lines corresponding to adjacent pixel column groups in different film layers, so that adjacent connecting data lines in the same film layer correspond to alternate pixel column groups, and the connecting data lines of alternate pixel column groups will not overlap in timing when charging, thereby avoiding the problem of signal crosstalk between the connecting data lines corresponding to adjacent pixel column groups, achieving high-quality and stable signal transmission, and ensuring a better display effect of the display device. Furthermore, compared to setting multiple first parts corresponding to adjacent pixel column groups on the same film layer, the wiring spacing of the first part on each film layer in the present application does not need to consider the crosstalk problem, so that the spacing between adjacent first parts can be smaller, thereby ensuring that the wiring area occupied by the first part in the first routing area is smaller, which is conducive to the miniaturized design of the display device.

For those skilled in the art, the present application may have various modifications and variations.
