Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] With the development of display technology, display panels have an increasingly higher screen-to-body ratio. Full-screen displays have attracted widespread attention due to their narrow or even borderless display effects. At present, display devices such as mobile phones and tablets often need to reserve space on the front for commonly used front cameras, infrared sensors, fingerprint recognition devices, earpieces and other electronic devices. For example, these photosensitive devices are set at the top of the front of the display device, and the corresponding position forms an opening area.

[0003] Since at least part of the data lines separated by the opening area need to be connected one-to-one by connecting wires, a larger wiring space needs to be provided around the opening area, which affects the screen-to-body ratio of the display screen. Summary of the invention

[0004] Embodiments of the present application provide a display panel and a display device, which can increase the screen-to-body ratio of the display panel.

[0005] In a first aspect, an embodiment of the present application provides a display panel, comprising: a functional device area; a display area surrounding the functional device area; data lines, a plurality of data lines being arranged along a first direction and extending along a second direction, the first direction intersecting with the second direction, the data lines comprising a first type of data lines, the first type of data lines being divided into a first data segment and a second data segment by the functional device area; data connection lines electrically connecting the first data segment and the second data segment; at least some of the data connection lines being arranged in the display area.

[0006] Based on the same inventive concept, in a second aspect, an embodiment of the present application provides a display device, comprising a display panel as in the embodiment of the first aspect.

[0007] According to the display panel and display device provided in the embodiments of the present application, since at least part of the data connection lines are arranged in the display area, the number of wirings in the functional device area can be reduced, thereby reducing the area of ​​the functional device area, that is, reducing the area of ​​the non-display area, thereby increasing the area of ​​the display area, which is beneficial to improving the screen-to-body ratio of the display panel.

[0028] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article 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, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0030] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region. Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.

[0031] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0032] In the embodiments of the present application, the term “electrically connected” may refer to a direct electrical connection between two components, or may refer to an electrical connection between two components via one or more other components.

[0033] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

[0034] The embodiments of the present application provide a display panel and a display device. The display panel and the display device provided by the embodiments of the present application will be introduced below with reference to the accompanying drawings.

[0035] Figure 1 A schematic top view of a display panel provided in an embodiment of the present application is shown. Figure 2 Show Figure 1 An exemplary partial enlarged view of the Q1 region in FIG. Figure 1 and Figure 2 As shown, the display panel 100 may include a functional device region R, a display region AA surrounding the functional device region R, and a data line 10 and a data connection line 20 .

[0036] The functional device area R may be a non-display area or a light-transmitting display area. Electronic devices may be arranged in the functional device area R. The electronic devices include but are not limited to a front camera, an infrared sensing device, a fingerprint recognition device, an earpiece, and the like.

[0037] The shape of the functional device area R can be a racetrack, an ellipse, a circle, a rectangle, etc. In the drawings of the present application, the shape of the functional device area R is shown as a racetrack, which is not intended to limit the present application.

[0038] Figure 1 The middle functional device region R is exemplarily arranged at the upper left, but this is not used to limit the specific position of the functional device region R. The position of the functional device region R can be set according to actual needs.

[0039] The data line 10 is located in the display area AA. The data line 10 extends along the second direction Y, and the plurality of data lines 10 are arranged along the first direction X. The first direction X intersects with the second direction Y. As an example, the first direction X may be a row direction, and the second direction Y may be a column direction.

[0040] Since electronic devices are to be placed in the functional device region R, at least the data line corresponding to the position where the electronic device is located will be divided into two parts. Therefore, the data line 10 may include a first type of data line 11, and the first type of data line 11 is divided into a first data segment 111 and a second data segment 112 by the functional device region R. Here, the first type of data line 11 may at least correspond to the position where the electronic device is located.

[0041] In the second direction Y, the first data segment 111 is located above the functional device area R, and the second data segment 112 is located below the functional device area R. In addition, some data lines 10 may not be separated by the functional device area R, and these data lines are continuous in the second direction Y. Parts of these data lines that are continuous in the second direction Y may be arranged outside the functional device area R, and some may pass through the functional device area R.

[0042] The data connection line 20 electrically connects the first data segment 111 and the second data segment 112. At least part of the data connection lines 20 are disposed in the display area AA. The data connection lines 20 may detour around the functional device area R in the display area AA.

[0043] In the embodiment of the present application, since at least part of the data connection lines 20 are arranged in the display area AA, the number of wirings in the functional device area R can be reduced, and the area of ​​the functional device area R can be reduced. When the functional device area R is a non-display area, the area of ​​the non-display area is reduced, thereby increasing the area of ​​the display area, which is beneficial to improving the screen-to-body ratio of the display panel; when the functional device area R is a translucent display area, the transmittance of the functional device area R can be increased.

[0044] Figure 3 Show Figure 1 Another exemplary partial enlarged view of the Q1 region in FIG. Figure 3 As shown, the functional device area R may include at least two light-transmitting areas R1 arranged along the first direction X. In this embodiment and the following embodiments, the functional device area is taken as a non-display area for example. The light-transmitting area in the functional device area can be understood as an opening area or a transmission area capable of transmitting light and / or sound. Light and / or sound can be output from the electronic device to the outside or travel from the outside toward the electronic device. The electronic device can be set corresponding to the light-transmitting area. Although in Figure 3 In some of the drawings below, the number of light-transmitting regions is two, but the present application is not limited thereto and may include three or more light-transmitting regions.

[0045] The area surrounding the light-transmitting area R1 in the functional device area R may be called a frame area R2 . A through hole may be provided at the location of the light-transmitting area R1 , or a blind hole or a part of the light-emitting pixels may be provided.

[0046] The data connection line 20 may include at least two connection line groups corresponding to the at least two light-transmitting regions R1 one by one. Figure 3 Taking the number of two light-transmitting regions as an example, for the sake of convenience, the two light-transmitting regions R1 can be respectively referred to as the first light-transmitting region R11 and the second light-transmitting region R12, the first light-transmitting region R11 corresponds to the connection line group a, and the second light-transmitting region R12 corresponds to the connection line group b. Each connection line group may include a plurality of data connection lines 20. The data connection lines 20 in the connection line group a connect the first data segment 111 and the second data segment 112 separated by the first light-transmitting region R11. The data connection lines 20 in the connection line group b connect the first data segment 111 and the second data segment 112 separated by the second light-transmitting region R12.

[0047] In the first direction X, each connection line group winds around the same position of its corresponding light-transmitting area. For example, each connection line group winds around the left side of its corresponding light-transmitting area, or each connection line group winds around the right side of its corresponding light-transmitting area.

[0048] As an example, please refer to Figure 1 and Figure 3 , in the first direction X, the display area AA may include a first edge a1 and a second edge a2 opposite to each other. Each connection line group detours on the side of its corresponding light-transmitting area close to the first edge a1, and light-transmitting areas are separated from different connection line groups. For example, the data connection lines in the connection line group a detour on the left side of the first light-transmitting area R11, and the data connection lines 20 in the connection line group b detour on the left side of the second light-transmitting area R12, and the first light-transmitting area R11 is separated from the connection line group a and the connection line group b.

[0049] In the embodiment of the present application, the first light-transmitting area R11 and its corresponding connecting line group 20a and the second light-transmitting area R12 and its corresponding connecting line group 20b can be arranged symmetrically as a whole, so that the influence of the first light-transmitting area R11 and its corresponding connecting line group 20a on the display effect of the surrounding display area and the influence of the second light-transmitting area R12 and its corresponding connecting line group 20b on the display effect of the surrounding display area can tend to be symmetrical, thereby reducing the difference in the influence of different light-transmitting areas on the display effect of the surrounding display area, thereby improving the display uniformity.

[0050] although Figure 1 In some of the following figures, the first edge a1 is the left edge and the second edge a2 is the right edge. In some examples, the first edge a1 may be the right edge and the second edge a2 may be the left edge.

[0051] For example, Figure 1 As shown, the functional device region R may be close to one of the first edge a1 and the second edge a2. For example, when each connecting line group detours on one side of its corresponding light-transmitting region close to the first edge a1, the functional device region R may be disposed close to the first edge a1.

[0052] Figure 4 Show Figure 1 Another exemplary partial enlarged view of the Q1 region in FIG. Figure 4 As shown, the functional device region R may include at least two light-transmitting regions R1 arranged along the first direction X. The region surrounding the light-transmitting region R1 in the functional device region R may be called a frame region R2, and a through hole may be correspondingly provided at the location of the light-transmitting region R1.

[0053] The data connection line 20 may include at least two connection line groups corresponding to the at least two light-transmitting regions R1 one by one. Figure 4 Taking the number of two light-transmitting regions as an example, for the convenience of introduction, the two light-transmitting regions can be respectively referred to as the first light-transmitting region R11 and the second light-transmitting region R12, the first light-transmitting region R11 corresponds to the connection line group a, and the second light-transmitting region R12 corresponds to the connection line group b. Each connection line group may include a plurality of data connection lines 20. The data connection lines 20 in the connection line group a connect the first data segment 111 and the second data segment 112 separated by the first light-transmitting region R11. The data connection lines 20 in the connection line group b connect the first data segment 111 and the second data segment 112 separated by the second light-transmitting region R12. In the first direction X, different connection line groups all detour at different positions of their corresponding light-transmitting regions.

[0054] As an example, Figure 4 As shown, the light-transmitting region R1 includes adjacent first and second light-transmitting regions R11 and R12. The connecting wire group 20a corresponding to the first light-transmitting region R11 detours on the right side of the first light-transmitting region R11, and the connecting wire group 20b corresponding to the second light-transmitting region R12 detours on the left side of the second light-transmitting region R12.

[0055] In this way, the first light-transmitting area R11 and its corresponding connecting line group 20a and the second light-transmitting area R12 and its corresponding connecting line group 20b can also be arranged symmetrically as a whole, so that the influence of the first light-transmitting area R11 and its corresponding connecting line group 20a on the display effect of the surrounding display area and the influence of the second light-transmitting area R12 and its corresponding connecting line group 20b on the display effect of the surrounding display area can tend to be symmetrical, thereby reducing the difference in the influence of different light-transmitting areas on the display effect of the surrounding display area, thereby improving the display uniformity.

[0056] Specifically, the two connecting wire groups 20a and 20b corresponding to the first light-transmitting region R11 and the second light-transmitting region R12 can detour between the first light-transmitting region R11 and the second light-transmitting region R12. In other words, the data connecting wires 20 in the two connecting wire groups 20a and 20b can pass through the inner sides of the first light-transmitting region R11 and the second light-transmitting region R12. In addition, the connecting wire group 20a can be arranged close to the first light-transmitting region R11, and the connecting wire group 20b can be arranged close to the second light-transmitting region R12, so that the data connecting wires 20 in different connecting wire groups can be avoided from crossing, thereby avoiding the coupling of the data connecting wires 20 in different connecting wire groups.

[0057] As an example, Figure 5 As shown, the light-transmitting area R1 includes adjacent first light-transmitting areas R11 and second light-transmitting areas R12. In the first direction X, the connecting line group 20a corresponding to the first light-transmitting area R1 detours on the side of the first light-transmitting area R11 away from the second light-transmitting area R12, and the connecting line group 20b corresponding to the second light-transmitting area R12 detours on the side of the second light-transmitting area R12 away from the first light-transmitting area R11. In this way, each connecting line group detours outside the functional device area R, and the data connecting lines 20 can be arranged in the display area AA, which can further reduce the number of wiring in the functional device area R, thereby further increasing the area of ​​the display area, which is conducive to increasing the screen-to-body ratio of the display panel.

[0058] In some optional embodiments, such as Figures 2 to 5 As shown in any of the accompanying drawings, the number of data connection lines 20 in each connection line group is equal. For example, the number of data connection lines 20 in the connection line group 20a corresponding to the first light-transmitting area R11 and the number of data connection lines 20 in the connection line group 20b corresponding to the second light-transmitting area R12 may be equal. It should be noted that the number of data connection lines 20 in the connection line group herein is merely exemplary, and in order to more clearly illustrate different routings, the number of data connection lines 20 in the connection line group is only illustrated as two, which is not intended to limit the present application. It is understandable that the number of data connection lines 20 in the connection line group can be set to more according to actual conditions.

[0059] In the embodiment of the present application, by setting the number of data connection lines 20 in each connection line group to be equal, the distribution pattern of the data connection lines in each connection line group can be set to be the same in terms of arrangement, which is conducive to achieving display uniformity.

[0060] As an example, the widths of the plurality of light-transmitting regions R1 in the first direction X are equal. For example, the plurality of light-transmitting regions R1 are all circles with the same radius. Of course, the shape of the light-transmitting region R1 may also be an ellipse, a rectangle, a square, etc. The shapes of the light-transmitting regions R1 shown in the drawings of the present application are only some examples and are not intended to limit the present application.

[0061] As another example, Figure 6 As shown, the functional device region R includes a first light-transmitting region R11 and a second light-transmitting region R12 arranged along a first direction X. In the first direction X, the width of the first light-transmitting region R11 is greater than the width of the second light-transmitting region R12. For example, the first light-transmitting region R11 and the second light-transmitting region R12 are both circular, and the radius of the first light-transmitting region R11 is greater than the radius of the second light-transmitting region R12. The first light-transmitting region R11 corresponds to the connecting line group 20a, and the second light-transmitting region R12 corresponds to the connecting line group 20b. The number of data connecting lines 20 included in the connecting line group 20a corresponding to the first light-transmitting region R11 may be greater than the number of data connecting lines 20 included in the connecting line group 20b corresponding to the second light-transmitting region R12.

[0062] Since the width of the first light-transmitting region R11 in the first direction X is relatively large, the number of first-type data lines 11 separated by the first light-transmitting region R11 is relatively large. Therefore, the number of data connection lines 20 corresponding to the first light-transmitting region R11 can be set to be relatively large to achieve the connection of the first-type data lines 11 separated by the first light-transmitting region R11.

[0063] In the case where the number of data connection lines corresponding to different light-transmitting areas is different, the data connection lines corresponding to the light-transmitting areas are still taken as one connection line group as an example. Figure 6 The illustrated connecting wire groups are all on the left side of their corresponding light-transmitting areas. The distribution of the connecting wire groups corresponding to each light-transmitting area can be as follows: Figure 4 or Figure 5 The distribution shown.

[0064] In some optional embodiments, such as Figure 3 As shown, the functional device region R may include at least two light-transmitting regions R1 arranged along the first direction X, and the data connection line 20 may include at least two connection line groups corresponding to the at least two light-transmitting regions R1. The two light-transmitting regions R1 may be respectively referred to as the first light-transmitting region R11 and the second light-transmitting region R12, the first light-transmitting region R11 corresponds to the connection line group a, and the second light-transmitting region R12 corresponds to the connection line group b. Each connection line group may include a plurality of data connection lines 20. The data connection lines 20 in the connection line group a connect the first data segment 111 and the second data segment 112 separated by the first light-transmitting region R11. The data connection lines 20 in the connection line group b connect the first data segment 111 and the second data segment 112 separated by the second light-transmitting region R12.

[0065] The data connection line 20 may include a first connection segment 21 extending along the first direction X and a second connection segment 22 extending along the second direction Y, wherein the second connection segment 22 is connected between two first connection segments 21. One first connection segment 21 may be connected to the first data segment 111, and another first connection segment 21 may be connected to the second data segment 22.

[0066] Exemplarily, the first connection section 21 and the second connection section 22 may be located in the same film layer or in different film layers. In the case of being located in different film layers, the first connection section 21 and the second connection section 22 may be connected through a via. Two first connection sections 21 in the same data connection line 200 may be located in the same film layer. Different second connection sections 22 may be located in the same film layer.

[0067] Multiple second connection segments 22 in the same connection line group are arranged in the first direction X. For example, multiple second connection segments 22 in connection line group a are arranged in the first direction X, and multiple second connection segments 22 in connection line group b are arranged in the first direction X.

[0068] In at least one connection line group, the i-th second connection segment 22 is farther away from the light-transmitting area R1 corresponding to the connection line group than the j-th second connection segment 22, the routing length of the i-th second connection segment 22 is Li, and the routing length of the j-th second connection segment 22 is Lj, Li>Lj. Since the routing length of the i-th second connection segment 22 on the outside is longer, in the second direction Y, the first connection segment 21 connected to the i-th second connection segment 22 can be farther away from the corresponding light-transmitting area R1 than the first connection segment 21 connected to the j-th second connection segment 22, so that the two data connection lines 20 belonging to the i-th second connection segment 22 and the j-th second connection segment 22 can be avoided from crossing, thereby reducing or even eliminating the coupling effect between the two, and improving display uniformity.

[0069] The i-th second connection segment 22 may be adjacent to the j-th second connection segment 22. In at least one connection line group, in the direction from the connection line group to its corresponding light-transmitting area, the routing lengths of the second connection segments 22 may decrease in sequence, and at this time, any two data connection lines 20 in the connection line group may not cross.

[0070] like Figure 7 As shown, the display panel may include sub-pixels 30 distributed in an array. Sub-pixels 30 in the same column may be connected to the same data line 10. The data line 10 may be used to transmit data signals from the driver chip to the sub-pixels 30 connected thereto, and the sub-pixels 30 may emit light of corresponding brightness according to the data signals received thereto. It is understandable that the first type of data line 11 is divided into a first data segment 111 and a second data segment 112, and the first data segment 111 and the second data segment 112 are connected via a data connection line 20. For example, the driver chip may be on a side of the second data segment 112 away from the functional device area R, and the data signal provided by the driver chip may pass through the second data segment 112, the data connection line 20, and then reach the first data segment 111.

[0071] However, the different lengths of the data connection line 20 will lead to inconsistent delays of the data signal. The longer the length of the data connection line 20, the more serious the delay of the data signal. When the voltage on the data line 10 connected to the data connection line 20 is switched, for example, when the span of the voltage switching is large, especially when switching from a high voltage to a low voltage, due to the delay of the data signal, a higher voltage may be written to the sub-pixel, thereby making the brightness dim.

[0072] The routing length of the second connection section 22 in the data connection line 20 may be greater than the routing length of the first connection section 21. The routing lengths of different data connection lines 20 may mainly depend on the routing lengths of their second connection sections 22. The longer the routing length of the second connection section 22, the longer the routing length of the data connection line 20 to which it belongs.

[0073] At least in the same connection line group, when the routing length of the i-th second connection segment 22 is greater than the routing length of the j-th second connection segment 22, the data line 10 connected to the i-th second connection segment 22 is electrically connected to the sub-pixels 30 of m1 colors, and the data line 10 connected to the j-th second connection segment 22 is electrically connected to the sub-pixels 30 of m2 colors, and m1<m2.

[0074] The longer i-th second connection segment 22 electrically connects fewer sub-pixels of different colors, so the voltage switching possibility on the data line connected thereto is smaller, thereby reducing the impact of the delay caused by the longer routing length of the i-th second connection segment 22.

[0075] As an example, m1 = 1, m2 = 2. The i-th longer second connection segment 22 electrically connects sub-pixels of one color, and the j-th shorter second connection segment 22 electrically connects sub-pixels of two colors.

[0076] like Figure 7 or Figure 8 As shown, the sub-pixel 30 may include sub-pixels of three colors, namely a first sub-pixel 31, a second sub-pixel 32 and a third sub-pixel 33. The same fill in the drawings may represent sub-pixels of the same color.

[0077] The first sub-pixel 31 may be a red light-emitting sub-pixel, the second sub-pixel 32 may be a green light-emitting sub-pixel, and the third sub-pixel 33 may be a blue light-emitting sub-pixel. The first sub-pixel 31 and the third sub-pixel 33 may be located in the same column, and the second sub-pixel 32 may be located in a separate column. The first sub-pixel 31 and the third sub-pixel 33 located in the same column may be connected to the same data line 10, and the second sub-pixel 32 located in the same column may be connected to the same data line 10.

[0078] Exemplarily, the data line 10 connected to the longer i-th second connection segment 22 can be electrically connected to the green-emitting sub-pixel, and the data line 10 connected to the shorter j-th second connection segment 22 can be electrically connected to the red-emitting sub-pixel and the blue-emitting sub-pixel. Since the red-emitting sub-pixel and the blue-emitting sub-pixel are more sensitive to the delay of the data voltage, the red-emitting sub-pixel and the blue-emitting sub-pixel are electrically connected to the shorter j-th second connection segment 22, which can reduce the impact of the delay of the data voltage on the red-emitting sub-pixel and the blue-emitting sub-pixel. The green-emitting sub-pixel is relatively less sensitive to the delay of the data voltage when there is no voltage switching, so the green-emitting sub-pixel is electrically connected to the longer i-th second connection segment 22, so that the display uniformity of sub-pixels of different colors can be improved.

[0079] Specifically, Figure 7 or Figure 8 As shown, the longer i-th second connection segment 22 can be electrically connected to the second sub-pixel 32 , and the shorter j-th second connection segment 22 can be electrically connected to the first sub-pixel 31 and the third sub-pixel 33 .

[0080] In some optional embodiments, the routing length of the first connection segment 21 connected to the i-th second connection segment 22 is Hi, and the routing length of the first connection segment 21 connected to the j-th second connection segment 22 is Hj. Figure 7 and Figure 8 As shown, in at least one same connection line group, Hi≥Hj. Since Li>Lj, in this case, the overall length of the data connection line 20 to which the i-th second connection segment 22 belongs is greater than the overall length of the data connection line 20 to which the j-th second connection segment 22 belongs. For example, the i-th second connection segment 22 and the j-th second connection segment 22 may be adjacent, and in at least one connection line group, in the direction from the connection line group to its corresponding light-transmitting area, the overall length of the data connection line 20 may decrease successively, so that the signal delay caused by the length of the data connection line 20 also changes gradually, which can avoid a sudden change in the signal delay caused by the length of the data connection line 20, thereby avoiding a sudden change in the display effect, and further improving the display uniformity.

[0081] In addition, when Hi=Hj, the difference in the overall length of each data connection line 20 in the same connection line group is only the difference in the length of each second connection segment 22. For example, the length differentiation of each second connection segment 22 can be minimized, which is more conducive to reducing the difference in the overall length of each data connection line 20 in the same connection line group.

[0082] As an example, Figure 7 As shown, in any connecting line group, Hi>Hj.

[0083] As another example, Figure 8 As shown, in any connecting line group, Hi=Hj.

[0084] As another example, Fig. 9 As shown, in some connecting wire groups, Hi>Hj; in other connecting wire groups, Hi=Hj. For example, in connecting wire group 20a, Hi>Hj. In connecting wire group 20b, Hi=Hj.

[0085] Exemplarily, the routing lengths of two first connection segments 21 in the same number of connection lines 20 are the same.

[0086] In some optional embodiments, please refer to Figure 1 and Fig.10 The display area AA includes a first edge a1 and a second edge a2 opposite to each other in the first direction X. Each light-transmitting area R1 is arranged close to the first edge a1. The light-transmitting area R1 includes a first light-transmitting area R11 and a second light-transmitting area R12. The first light-transmitting area R11 is closer to the first edge a1 than the second light-transmitting area R12.

[0087] The routing length of the i-th second connection segment 22 corresponding to the first light-transmitting region R11 is L1i, the routing length of the j-th second connection segment j corresponding to the first light-transmitting region R11 is L1j, the routing length of the i-th second connection segment 22 corresponding to the second light-transmitting region R12 is L2i, and the routing length of the j-th second connection segment corresponding to the second light-transmitting region R12 is L2j; L1i>L2i, L1j>L2j.

[0088] In this way, in the direction from left to right, the routing length of the second connecting segment 22 corresponding to the first light-transmitting area R11 is generally greater than the routing length of the second connecting segment 22 corresponding to the second light-transmitting area R12. The signal delay caused by the connecting line group 20a to the connecting line group 20b can gradually change, which can avoid sudden changes in the signal delay and further avoid sudden changes in the display effect, thereby further improving the display uniformity.

[0089] For example, Fig.10 As shown, the shortest second connection segment 22 in the connection line group 20a and the longest second connection segment 22 in the connection line group 20b are closest, and the i-th second connection segment 22 and the j-th second connection segment 22 in each connection line group may be adjacent. The routing length of the second connection segment 22 in each connection line group may gradually decrease from left to right. Optionally, the routing length of the shortest second connection segment 22 in the connection line group 20a may be greater than the routing length of the longest second connection segment 22 in the connection line group 20b.

[0090] In the embodiment of the present application, the difference in the length of any two adjacent second connection segments 22 in the connection line group 20a is ΔL, and the difference in the length of any two adjacent second connection segments 22 in the connection line group 20b is ΔL.

[0091] Furthermore, the difference between the wiring length of the shortest second connection segment 22 in the connection line group 20 a and the wiring length of the longest second connection segment 22 in the connection line group 20 b may also be ΔL.

[0092] In some optional embodiments, please refer to Figure 1 and Figure 3 The display area AA includes a first edge a1 and a second edge a2 opposite to each other in the first direction X. Each light-transmitting area R1 is arranged close to the first edge a1. The light-transmitting area R1 includes a first light-transmitting area R11 and a second light-transmitting area R12. The first light-transmitting area R11 is closer to the first edge a1 than the second light-transmitting area R12.

[0093] The routing length of the i-th second connection segment 22 corresponding to the first light-transmitting region R11 is L1i, the routing length of the j-th second connection segment j corresponding to the first light-transmitting region R11 is L1j, the routing length of the i-th second connection segment 22 corresponding to the second light-transmitting region R12 is L2i, and the routing length of the j-th second connection segment corresponding to the second light-transmitting region R12 is L2j; L1i=L2i, L1j=L2j.

[0094] In this way, the symmetry between the first light-transmitting area R11 and its corresponding connecting line group 20a and the second light-transmitting area R12 and its corresponding connecting line group 20b can be improved, so that the influence of the first light-transmitting area R11 and its corresponding connecting line group 20a on the display effect of the surrounding display area and the influence of the second light-transmitting area R12 and its corresponding connecting line group 20b on the display effect of the surrounding display area are more symmetrical, further reducing the difference in the influence of different light-transmitting areas on the display effect of the surrounding display area, thereby further improving the display uniformity.

[0095] In the embodiment of the present application, the routing length of the second connection segment 22 in each connection line group may be gradually reduced in the direction from left to right. The difference in routing length between any two adjacent second connection segments 22 in the connection line group 20a is ΔL, and the difference in routing length between any two adjacent second connection segments 22 in the connection line group 20b is ΔL. The routing length of the longest second connection segment 22 corresponding to the first light-transmitting region R11 may be greater than the routing length of the longest second connection segment 22 corresponding to the second light-transmitting region R12. The routing length of the longest second connection segment 22 in the connection line group 20a is equal to the routing length of the longest second connection segment 22 in the connection line group 20b, and the routing length of the shortest second connection segment 22 in the connection line group 20a is equal to the routing length of the shortest second connection segment 22 in the connection line group 20b.

[0096] Herein, the i-th second connection segment 22 in different connection line groups is two second connection segments at the same relative position, and the j-th second connection segment 22 in different connection line groups is two second connection segments at the same relative position. The relative position can be understood as the position of the second connection segment relative to the corresponding light-transmitting area. For ease of understanding, as an example, the i-th second connection segment can be the second connection segment farthest from the corresponding light-transmitting area in the first direction, and the j-th second connection segment can be the second connection segment with the second farthest distance from the corresponding light-transmitting area in the first direction.

[0097] In some optional embodiments, in combination with reference Fig.11 and Fig.12 As shown, the display panel 100 may further include a non-display area NA, and the non-display area NA may include a step area BA. The step area BA may include a data signal terminal ( Fig.11 The data signal terminal may be directly or indirectly connected to the driving chip, and the driving chip may provide a data signal.

[0098] The display panel may further include an auxiliary connection line 40 . The auxiliary connection line 40 may be located in the display area AA. At least a portion of the data line 10 is connected to the step area BA of the display panel through the auxiliary connection line 40 .

[0099] The data connection line 20 may be connected to the first data segment 111 through the first via h1, and the data connection line 20 may be connected to the second data segment 112 through the second via h2. Specifically, one of the first connection segments 21 of the data connection line 20 is connected to the first data segment 111 through the first via h1, and another first connection segment 21 of the data connection line 20 is connected to the second data segment 112 through the second via h2, and at least part of the second data segment 112 is electrically connected to the auxiliary connection line 40 through the second via h2.

[0100] For example, each auxiliary connection line 40 needs to be connected to each data line 10 through a via.

[0101] In the embodiment of the present application, since the second data segment 112 is connected to the data connection line 20 and the auxiliary connection line 40 through a second via h2, the number of required vias can be reduced. Since coupling effects may also occur between vias and other wirings or devices, affecting display uniformity, by reducing the number of vias, the coupling effects can be reduced and the display effect can be improved. Optionally, the data connection line 20 and the auxiliary connection line 40 can be set in the same film layer, which can reduce the process.

[0102] Exemplarily, each data connection line 20 corresponding to the first light-transmitting region R11 may share the second via h2 with the auxiliary connection line 40 , and the first type data lines 11 separated by the second light-transmitting region R12 may be connected to the step area BA without the auxiliary connection line 40 .

[0103] In some optional embodiments, such as Fig.13 As shown, at least a portion of the second data segment 112 can be connected to the auxiliary connection line 40 through the third via h3, and the second via h2 is closer to the functional device region R than the third via h3.

[0104] In the embodiment of the present application, since the second data segment 112 is respectively connected to the data connection line 20 and the auxiliary connection line 40 through different vias, it is more conducive to the consistency of the distribution pattern of the data connection lines corresponding to different light-transmitting areas, thereby facilitating the realization of display uniformity.

[0105] For example, the second vias h2 between the data connection 20 and the second data segment 112 may be close to the functional device region R, and the third vias h3 between the data line 10 and the auxiliary connection 40 may be far away from the functional device region R.

[0106] In some optional embodiments, such as Fig.13 As shown, the auxiliary connection line 40 may include a first auxiliary segment 41 extending along the first direction X and a second auxiliary segment 42 extending along the second direction Y. The routing lengths of the first auxiliary segments 41 may be equal. For example, the distances between adjacent first auxiliary segments 41 in the second direction Y may be equal.

[0107] Exemplarily, the first auxiliary segment 41 and the second auxiliary segment 42 in the same auxiliary connecting line 40 may be located in different film layers, in which case the first auxiliary segment 41 and the second auxiliary segment 42 may be connected via vias. Different first auxiliary segments 41 may be located in the same film layer, and different second auxiliary segments 42 may be located in the same film layer.

[0108] As an example, the first auxiliary segment 41 and the first connecting segment 21 may be located in the same film layer. The second auxiliary segment 42 and the second connecting segment 22 may be located in the same film layer.

[0109] In some optional embodiments, such as Fig.12 As shown, the connecting vias h2 between the auxiliary connecting line 40 and the data line 10 may be arranged along the third direction Z, or as shown in FIG. Fig.13 As shown, the connection vias h3 between the auxiliary connection line 40 and the data line 10 may be arranged along the third direction Z, and the third direction Z intersects both the first direction X and the second direction Y. Exemplarily, the connection vias between the auxiliary connection line 40 and the data line 10 may be arranged from the lower left corner of the display area toward the upper right corner of the display area.

[0110] In some optional embodiments, in combination with reference Fig.11 and Fig.12 The display area AA includes a first edge a1 and a second edge a2 opposite to each other in the first direction X. The wiring length of the second auxiliary segment 42 may gradually increase along the first direction X and in a direction away from the first edge a1.

[0111] Exemplarily, the intervals between adjacent first auxiliary segments 41 in the second direction Y may be equal. Optionally, the intervals between adjacent second auxiliary segments 42 in the first direction X may be equal.

[0112] In some optional embodiments, such as Fig.12 As shown, the functional device area R may include at least two light-transmitting areas R1 arranged along the first direction X. The data connection line 20 may include at least two connection line groups corresponding to the at least two light-transmitting areas R1. For the convenience of introduction, the two light-transmitting areas R1 may be respectively referred to as the first light-transmitting area R11 and the second light-transmitting area R12, the first light-transmitting area R11 corresponds to the connection line group a, and the second light-transmitting area R12 corresponds to the connection line group b. Each connection line group may include a plurality of data connection lines 20. The data connection lines 20 in the connection line group a connect the first data segment 111 and the second data segment 112 separated by the first light-transmitting area R11. The data connection lines 20 in the connection line group b connect the first data segment 111 and the second data segment 112 separated by the second light-transmitting area R12.

[0113] The data connection line 20 may include a first connection segment 21 extending along a first direction X and a second connection segment 22 extending along a second direction Y, wherein the second connection segment 22 is connected between the two first connection segments 21;

[0114] In at least one same connection line group, the routing length of the i-th second connection segment 22 is Li, and the routing length of the j-th second connection segment 22 is Lj, Li>Lj. The routing length of the second auxiliary segment 42 connected to the i-th second connection segment 22 is Di, and the routing length of the second auxiliary segment 42 connected to the j-th second connection segment 22 is Dj, Di<Dj. In this way, the total length of Li and Di can be roughly equal to the total length of Lj and Dj, that is, the sum of the routing lengths of the i-th second connection segment 22 and the second auxiliary segment 42 connected thereto can be roughly equal to the sum of the routing lengths of the j-th second connection segment 22 and the second auxiliary segment 42 connected thereto, so that the signal delay corresponding to the i-th second connection segment 22 and the second auxiliary segment 42 connected thereto tends to be consistent with the signal delay corresponding to the j-th second connection segment 22 and the second auxiliary segment 42 connected thereto, thereby improving display uniformity.

[0115] In order to better understand the connection relationship between the second connecting section 22 and the second auxiliary section 42, as shown in FIG. Fig.12As shown, data lines d1 to d16 may be arranged in the direction from left to right. Data lines d5 and d6 may be divided into two sections by the first light-transmitting region R11, and the two separated sections of data lines d5 and d6 are connected by the data connection line in the connection line group 20a. Data lines d11 and d12 may be divided into two sections by the second light-transmitting region R12, and the two separated sections of data lines d11 and d12 are connected by the data connection line in the connection line group 20b. Data lines d7, d8, d9, and d10 may pass through the functional device region R. Of course, at least one of data lines d7, d8, d9, and d10 may also be divided into two sections by the functional device region R, and then the two separated sections may be connected by the data connection line. Data lines d1, d2, d3, d4, d13, d14, d15, and d16 may be outside the functional device region R.

[0116] For example, the two separated segments of the data line d5 can be connected via the i-th second connection segment 22 in the connection line group 20a, and the second auxiliary segment 42 connected to the data line d5 is connected to the i-th second connection segment 22 in the connection line group 20a. The two separated segments of the data line d6 can be connected via the j-th second connection segment 22 in the connection line group 20a, and the second auxiliary segment 42 connected to the data line d6 is connected to the i-th second connection segment 22 in the connection line group 20a.

[0117] In some optional embodiments, such as Fig.12 or Fig.13 As shown, the second auxiliary segments 42 and the data lines 10 may be arranged alternately in the first direction X. Since there may be a coupling effect between the second auxiliary segments 42 and the data lines 10, by arranging the second auxiliary segments 42 and the data lines 10 in an alternate arrangement, the coupling effect between the second auxiliary segments 42 and the data lines 10 can be dispersed, or even evenly distributed, thereby improving display uniformity.

[0118] Exemplarily, at least one data line 10 may be distributed between two adjacent second auxiliary terminals 42. The number of data lines 10 distributed between any two adjacent second auxiliary terminals 42 may be equal.

[0119] As an example, in the present application, the second connection segments and the data lines 10 may be arranged alternately in the first direction X. At least one data line 10 may be distributed between two adjacent second auxiliary ends 42. In the same connection line group, the number of data lines 10 distributed between any two adjacent second auxiliary ends 42 may be equal.

[0120] In some optional embodiments, in combination with reference to Fig.14 , Fig.15 and Fig.16, a first fan-out line 51 and a second fan-out line 52 may be provided between the step area BA and the display area AA of the display panel. A portion of the data line 10 may be connected to the first fan-out line 51 through the auxiliary connection line 40 located in the display area AA, and another portion of the data line 10 may be connected to the second fan-out line 52. The first fan-out line 51 and the second fan-out line 52 may be connected to the data signal terminal in the step area BA. The orthographic projections of at least one first fan-out line 51 and at least one second fan-out line 52 on the light-emitting surface of the display panel intersect. If the first fan-out line 51 and the second fan-out line 52 do not intersect, it is easy to cause the arrangement order of the data line 10 to be different from the arrangement order of the data signal terminals to which the data lines are connected, resulting in an increased difficulty in the driver chip outputting data signals. When the first fan-out line 51 and the second fan-out line 52 are arranged crosswise, it is easy to achieve that the arrangement order of the data line 10 is the same as the arrangement order of the data signal terminals to which the data lines are connected, thereby avoiding increasing the difficulty in the driver chip outputting data signals.

[0121] For better understanding, the arrangement order of the data lines 10 is the same as the arrangement order of the data signal terminals connected to the data lines. Fig.15 and Fig.16 As shown, it is exemplarily shown that the data line 10 includes data lines d1~d16 arranged in sequence from left to right, and the data signal terminals include data signal terminals c1~c16 arranged in sequence from left to right. When the first fan-out line 51 and the second fan-out line 52 are cross-arranged, the data line d1 can correspond to the electrically connected data signal terminal c1, the data line d2 can correspond to the electrically connected data signal terminal c2, the data line d3 can correspond to the electrically connected data signal terminal c3, ..., the data line d16 can correspond to the electrically connected data signal terminal c16, so that the arrangement order of the data lines 10 is the same as the arrangement order of the data signal terminals to which the data lines are connected.

[0122] In some optional embodiments, such as Fig.17 As shown, the functional device area R may include at least two light-transmitting areas R1 arranged along the first direction X, and a first winding area R31 and a second winding area R32 are included between two adjacent light-transmitting areas R1. The first winding area R31 surrounds one of the light-transmitting areas R1, and the second winding area R32 surrounds the other light-transmitting area R1. Taking the two adjacent light-transmitting areas R1 as an example, the first winding area R31 surrounds the first light-transmitting area R11, and the second winding area R32 surrounds the second light-transmitting area R12. n1 data connection lines 20 are wound around the first winding area R31, and n2 data connection lines 20 are wound around the second winding area R32, and n1 and n2 are integers greater than or equal to 1.

[0123] In the embodiment of the present application, since the first winding area R31 and the second winding area R32 are between adjacent light-transmitting areas and data connection lines 20 are wound around the first winding area R31 and the second winding area R32, it is possible to avoid having all the data connection lines 20 winding around the display area around the functional device area R, and it is possible to avoid having the wiring in the display area around the functional device area R being too dense, thereby reducing the difference in wiring density between the display area around the functional device area R and the display area at other locations, thereby improving display uniformity.

[0124] Exemplarily, part of the plurality of data connection lines 20 corresponding to at least one light-transmitting region R1 may be detoured in the display region, and another part may be detoured in the corresponding winding region. For example, when the light-transmitting region R1 corresponds to an even number of data connection lines 20, the number of the even number of data connection lines 20 corresponding to the light-transmitting region R1 that detour in the display region and detour in the winding region may be equal.

[0125] In some optional embodiments, n1=n2. In this way, the data connection lines 20 can be evenly distributed, which helps to improve display uniformity.

[0126] In some optional embodiments, such as Fig.17 As shown, a wiring area R4 is included between the first winding area R31 and the second winding area R32 , and the data line 10 may further include a second type data line 12 , and the second type data line 12 passes through the wiring area R4 .

[0127] As an example, the driving circuits of the display panel may be arranged outside the wiring area R4. In other words, the driving circuit may not be arranged in the wiring area R4, so that no array film layer may be arranged in the wiring area R4, thereby reducing the interference of the driving circuit on the electronic devices arranged in the light-transmitting area. Here, no array film layer may be arranged in the wiring area R4, which can be understood as no transistors, capacitors and other components may be arranged in the wiring area R4, and the wiring area R4 may still include an inorganic layer and / or an organic layer.

[0128] like Fig.17 As shown, the data line 10 may further include a third type of data line 13 that is not separated by the functional device area R. For example, pixels that can emit light normally are called real pixels, and the number of real pixels electrically connected to the third type of data line 13 is greater than the number of real pixels electrically connected to the second type of data line 12, resulting in a difference in load between the second type of data line 12 and the third type of data line 13.

[0129] As another example, a virtual pixel (not shown in the figure) may be provided in the wiring area R4. The virtual pixel may include a pixel circuit and a light-emitting device, but the light-emitting device cannot emit light normally. The virtual pixel in the wiring area R4 may be electrically connected to the second-class data line 12, so that the load difference between the second-class data line 12 and the third-class data line 13 can be reduced, and the display uniformity can be improved.

[0130] Exemplarily, the total number of real pixels and virtual pixels electrically connected to the second-type data lines 12 may be equal to the total number of real pixels electrically connected to the third-type data lines 13 .

[0131] In some optional embodiments, such as Fig.18 As shown, the display panel 100 may further include a signal line 60 and a signal connection line 70. The signal line 60 extends along the first direction X, and a plurality of signal lines 60 may be arranged in the second direction Y. The signal line 60 may include a first type of signal line 61, and the first type of signal line 61 includes a first signal segment 611 and a second signal segment 612 separated by a functional device region R. The signal connection line 70 is connected between the first signal segment 611 and the second signal segment 612, and at least part of the signal connection line 70 is disposed in the display region AA.

[0132] In addition, some of the signal lines 60 may not be separated by the functional device region R, and these signal lines 60 are continuous in the first direction X. These continuous signal lines in the first direction X may all be arranged outside the functional device region R.

[0133] In the embodiment of the present application, since at least part of the signal connection lines 70 are arranged in the display area AA, the number of wirings in the functional device area R can be reduced, and the area of ​​the functional device area R can be reduced, that is, the area of ​​the non-display area is reduced, thereby increasing the area of ​​the display area, which is beneficial to improving the screen-to-body ratio of the display panel.

[0134] In some optional embodiments, the signal line 60 includes at least one of the following: a scan line, a light emitting control line, and an initialization signal line. The scan line can be used to provide a scan signal to the pixel circuit of the sub-pixel to control the conduction or shutdown of the transistor in the pixel circuit. The signal transmitted on the light emitting control line can control the sub-pixel to enter or end the light emitting phase. The initialization signal line can be used to transmit an initialization signal, which can initialize the anode of the light emitting element in the sub-pixel, and / or the initialization signal can initialize the gate of the driving transistor in the sub-pixel.

[0135] Exemplarily, the display panel provided in the present application may be an organic light-emitting diode (OLED) display panel. Those skilled in the art should understand that in other implementations of the present application, the display panel may also be a micro light-emitting diode (Micro LED) display panel, a quantum dot display panel, etc.
