[0043] In order to make the purposes, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, but not to limit the present application. The present application can be implemented without some of the specific details by those skilled in the art. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0044] It should be noted that, in this document, relational terms such as first and second and the like are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, an element defined by the statement "comprising" does not exclude the existence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0045] In a full-screen display device, a display panel includes a photosensitive region, a display region, and a transition region between the photosensitive region and the display region. A photosensitive device is arranged at a position corresponding to the photosensitive region in the display panel, and both the photosensitive region and the display region achieve display effects during use of the display panel to meet the needs of a full screen.

[0046] In the display panel design stage, in order to meet the placement needs of the photosensitive area at any position, the data line and the selection signal line for driving the photosensitive area to emit light need to be continuously extended. Usually, the selection signal line is arranged in the transition area and bypasses the photosensitive area. This results in a certain length difference between different selection signal lines, so that the load borne by different selection signal lines is different, affecting the display uniformity.

[0047] To solve the above problems, please refer to Figures 1 to 4 The embodiment of the present application provides a display panel 1, which has a first area A1, a second area A2 and a transition area A3 between the first area A1 and the second area A2, and the transmittance of the first area A1 is greater than that of the second area A2.

[0048] The display panel 1 comprises a plurality of first circuit groups 10 and a plurality of selection signal lines 20, the plurality of first circuit groups 10 are located in the transition area A3, the plurality of first circuit groups 10 are arranged side by side in a first direction X to form a first circuit row H, and the plurality of first circuit rows H are arranged side by side in a second direction Y, and the first direction X intersects the second direction Y.

[0049] In the direction parallel to the second direction Y and from the center of the first area A1 to the second area A2, the first row to the nth row of the first circuit row H are arranged in sequence, the first circuit row Hi in the ith row is electrically connected with the ith selection signal line 20i, and the first circuit groups 10 between adjacent first circuit groups 10 have a first interval area G1, the size of the first interval area G1 in the first direction X is L1, the first circuit row Hj in the jth row is electrically connected with the jth selection signal line 20j, and the first circuit groups 10 between adjacent first circuit groups 10 have a second interval area G2, the size of the second interval area G2 in the first direction X is L2, L1>L2, n, i and j are integers and 1≤j

[0050] Optionally, the first area A1 corresponds to the photosensitive area of the display panel 1, and the second area A2 corresponds to the main area of the display panel 1 for realizing the display effect. The display panel 1 can be provided with a photosensitive device such as a camera in the first area A1, and the first area A1 and the second area A2 are both provided with light emitting units to meet the needs of the full-screen display. The size and shape of the first area A1 and the second area A2 are not limited in the embodiment of the present application. For example, the shape of the first area A1 can be circular or drop-shaped.

[0051] The transition area A3 is arranged around the outside of the first area A1, and the size and shape of the transition area A3 are also not limited in the embodiment of the present application. For example, the outer contour of the transition area A3 can be a circular structure.

[0052] In order to improve the transmittance of the first area A1 to meet the light sensing needs of the display panel 1, at least part of the first circuit groups 10 and the selection signal lines 20 are arranged in the transition area A3. Among them, the first circuit groups 10 include one or more driving circuits for driving the light emitting units in the transition area A3 or in the first area A1 to emit light to realize a full-screen display.

[0053] The plurality of first circuit groups 10 are arranged side by side in the first direction X to form a first circuit row H, and a plurality of first circuit rows H are arranged side by side in the second direction Y. Exemplarily, the first direction X is perpendicular to the second direction Y. The number of first circuit groups 10 in the first circuit row H can be two, three or even more, and the number of first circuit groups 10 in different first circuit rows H can be the same or different, which is not limited by the embodiments of the present application.

[0054] The plurality of first circuit rows H are all located in the transition area A3, and the transition area A3 is divided into two regions in the first direction X by the first area A1. Only one of the two regions can be provided with the plurality of first circuit rows H, that is, the plurality of first circuit rows H are arranged on one side of the first area A1 in the first direction X. Alternatively, as shown in Figure 2 , the plurality of first circuit rows H are arranged in both regions, that is, the plurality of first circuit rows H are arranged on both sides of the first area A1 in the first direction X.

[0055] In the direction parallel to the second direction Y and pointing from the center of the first area A1 to the second area A2, the first row to the nth row of the first circuit rows H are arranged in sequence. In Figure 2 , the center of the first area A1 is schematically shown by a circle point, and the first row to the nth row of the first circuit rows H are schematically shown by numbers. As can be seen from the figure, the "direction pointing from the center of the first area A1 to the second area A2" mentioned in the embodiments of the present application can be a direction pointing from the center of the first area A1 to the upper second area A2, or a direction pointing from the center of the first area A1 to the lower second area A2. For the convenience of description, the embodiments of the present application will be described hereinafter taking the direction pointing from the center of the first area A1 to the upper second area A2 as an example.

[0056] In the second direction Y, the first circuit row H closest to the center of the first area A1 is the first row, and the first circuit row H farthest from the center of the first area A1 is the nth row. The ith row of the first circuit rows Hi is located on the side away from the center of the first area A1 of the jth row of the first circuit rows Hj, that is, the distance between the ith row of the first circuit rows Hi and the center of the first area A1 in the second direction Y is greater than the distance between the jth row of the first circuit rows Hj and the center of the first area A1 in the second direction Y.

[0057] The selection signal line 20 includes, but is not limited to, a scan signal line for providing a scan signal and a light-emitting control signal line for providing a light-emitting control signal line. One selection signal line 20 can correspond to one first circuit row H, specifically, one selection signal line 20 can pass through and connect at least part of the first circuit groups 10 in one first circuit row H at the same time. Further alternatively, one selection signal line 20 can pass through and connect all the first circuit groups 10 in one first circuit row H at the same time. Wherein the i-th selection signal line 20i can be electrically connected to the i-th first circuit row H i, and the j-th selection signal line 20j can be electrically connected to the j-th first circuit row H j.

[0058] It should be noted that, for one first circuit row H, only one selection signal line 20 can be connected, or multiple selection signal lines 20 can be connected at the same time. In combination with the drawings, Figure 2 A case where one first circuit row H is connected to only one selection signal line 20 is shown in FIG. Figure 5 Figure 5 A case where one first circuit row H is connected to multiple first selection signal lines 20 at the same time is shown in FIG.

[0059] In addition, please refer to Figure 6 In combination with the driving circuit in the first circuit group 10, the driving circuit has multiple forms, such as 7T1C and 8T1C, etc. For different kinds of driving circuits, the number of selection signal lines 20 required to be connected by a single driving circuit can be the same or different. Figure 6 The structure when the driving circuit is 7T1C is shown, at this time the selection signal line 20 can include the signal lines connected by S1, S2, S3, S4 and EM signals.

[0060] Due to the difference in extension length and other factors, the self-load of the j-th selection signal line 20j is different from the self-load of the i-th selection signal line 20i, thereby causing the transmission signal effect of the two to be different, and easily causing display abnormalities and other problems.

[0061] In view of this problem, the arrangement mode of the first circuit group 10 is adjusted in the embodiments of the present application, so as to reduce the load difference of the i-th selection signal line 20i and the j-th selection signal line 20j. Specifically, if two conductor structures placed horizontally are arranged at intervals, a lateral capacitance will be formed, and the greater the interval distance between the two conductor structures, the more space for generating an edge electric field, and the greater the corresponding lateral capacitance. In the embodiments of the present application, the multiple first circuit groups 10 in the first circuit row H are arranged at intervals from each other, which also generates a lateral capacitance, and the generated lateral capacitance acts on the selection signal line 20 electrically connected to the first circuit group 10, thereby causing the load of the selection signal line 20 to increase.​

[0062] On this basis, the embodiment of the present application sets the size L1 between the adjacent first circuit groups 10 in the first direction X in the first circuit row Hi in the ith row to be greater than the size L2 between the adjacent first circuit groups 10 in the first direction X in the first circuit row Hj in the jth row, so that the lateral capacitance in the first circuit row Hi in the ith row is greater than the lateral capacitance in the first circuit row Hj in the jth row, thereby optimizing the load difference of the ith and jth selection signal lines 20i and 20j, making the loads of the two tend to be consistent, ensuring that the effects of the transmitted signals are basically consistent, and reducing the risk of display abnormalities.

[0063] It should be noted that the specific values of i, j, and n are not limited by the embodiment of the present application. Wherein, j can be 1, or any other integer less than i; i can be n, or any integer greater than j and less than n. In addition, for the first circuit group 10, please refer to Figure 11 , the first circuit group 10 includes a plurality of first driving circuits 11, and each first driving circuit 11 is not a regular shape such as a rectangle, so the first circuit group 10 is also not a regular shape. On this basis, the first driving circuit 11 can be boxed out as shown in Figure 11 , the size of the box can be determined according to the actual situation, and the box needs to cover at least 90% or more of the structure in the first driving circuit 11. At this time, L1 can be the interval in the first direction X between the two boxes corresponding to the two first driving circuits 11 closest to each other in the adjacent two first circuit groups 10 in the first circuit row Hi in the ith row.

[0064] In addition, for the first circuit row H, the distances between different adjacent first circuit groups 10 inside it can be the same or different, and the embodiment of the present application does not limit it. When the distances between different adjacent first circuit groups 10 in the first circuit row H are different, L1 and L2 respectively represent the average distance between the adjacent first circuit groups 10 in the ith row first circuit row Hi and the jth row first circuit row Hj.

[0065] In some embodiments, as shown in Figure 2 , in the direction parallel to the second direction Y and directed from the center of the first area A1 to the second area A2, the interval between the adjacent first circuit groups 10 in the first direction X gradually increases in any two adjacent first circuit rows H.

[0066] The interval between the adjacent first circuit groups 10 in the first circuit row H gradually changes in the second direction Y, and the change trend includes but is not limited to linear change and exponential change. Compared with other schemes, this design can make the arrangement of the first circuit groups 10 more compact and reduce the change degree between the adjacent two first circuit rows H.

[0067] Generally, the selection signal lines 20 for connecting the adjacent two first circuit rows H are close to each other in position and have close extension lengths. Therefore, by controlling the interval between the adjacent first circuit groups 10 to gradually change, the corresponding lateral capacitances in the adjacent two first circuit rows H are close to each other, so that the adjacent selection signal lines 20 are close to each other in lateral capacitance influence, thereby reducing the load difference between the adjacent selection signal lines 20.

[0068] In some embodiments, referring to Figure 2 and Figure 7 , the size of the first circuit group 10 in the first direction X is P, the third interval G3 between the adjacent first circuit groups 10 in the qth first circuit row H has a size L3 in the first direction X, and L3 satisfies: wherein q, a, b and c are constants, and 1.0002≤a≤1.001, 1.0002≤b≤1.001, 30≤c≤50, and 1≤q≤n.

[0069] P is the size of the first circuit group 10 in the first direction X, and the size of each first circuit group 10 in the first direction X can be the same or different. When the sizes of the different first circuit groups 10 in the first direction X are different, P can be the average size of the first circuit groups 10 in the corresponding first circuit row H in the first direction X. The size of P depends on the number and arrangement of the driving circuits in the first circuit group 10, which is not limited in the embodiments of the present application.

[0070] q, a, b and c are constants, and the sizes of the four constants jointly limit the size L3 of the third interval in the first direction X. According to the formula , it can be known that the interval between the adjacent first circuit groups 10 changes exponentially, which makes the arrangement of the first circuit groups 10 close to the center of the first area A1 more compact and the arrangement of the first circuit groups 10 away from the center of the first area A1 more dispersed compared with the linear change and other change modes.

[0071] In the embodiment of the present application, by controlling the spacing between the first circuit groups 10 to change exponentially, the arrangement of the first circuit groups 10 in the transition area A3 is optimized, so that the arrangement of the first circuit groups 10 is more compact, thereby reducing the size of the space occupied by the plurality of first circuit groups 10, which is beneficial to reduce the influence of the first circuit groups 10 on the display effect and improve the full-screen display effect.

[0072] In some embodiments, referring to Figure 8 In the direction parallel to the second direction Y and pointing from the center of the first area A1 to the second area A2, the transition area A3 includes a first transition area A31 and a second transition area A32 in sequence, and in at least part of the different first circuit rows H in the first transition area A31, the spacing of adjacent first driving circuits 11 in the first direction X is the same. In at least part of the first circuit rows H in the second transition area A32, the spacing of adjacent first circuit groups 10 in the first direction X is greater than that in the first circuit rows H in the first transition area A31. In Figure 8 In the embodiment, the first transition area A31 and the second transition area A32 are schematically shown by thick dashed lines.

[0073] In the second direction Y, the first transition area A31 is located on one side of the second transition area A32 towards the center of the first area A1. The second transition area A32 can be provided with two, and the two second transition areas A32 are located on both sides of the first transition area A31 in the second direction Y.

[0074] In the first transition area A31, the spacing of adjacent first circuit groups 10 in the first direction X is the same in at least part of the different first circuit rows H. Further optionally, in the first transition area A31, the spacing of adjacent first circuit groups 10 in the first direction X is the same in each first circuit row H, so that the plurality of first circuit groups 10 located in the first transition area A31 are arranged compactly and regularly, thereby helping to reduce the size of the transition area A3. Exemplarily, the outer contour of the transition area A3 is a circular structure, and the diameter of the circular structure is 5500 μm. In the related art, the diameter corresponding to the transition area is usually 6700 μm, so the embodiment of the present application helps to reduce the size of the transition area A3 to improve the display effect of the display panel.

[0075] Compared with the first transition area A31, the spacing of adjacent first circuit rows H in the first direction X in the second transition area A32 is larger, and the corresponding lateral capacitance is larger, thereby better helping the selection signal line 20 to balance the load and improve the consistency of signal transmission.

[0076] The embodiment of the present application divides the transition area A3 into the first transition area A31 and the second transition area A32, and adjusts the arrangement of the first circuit groups 10 in the first transition area A31 and the second transition area A32, so that the first circuit groups 10 in the first transition area A31 are arranged more compactly, and the first circuit groups 10 in the second transition area A32 are arranged more dispersedly, which is beneficial to balancing the load and improving the signal transmission reliability. Meanwhile, this design makes the displacement of adjacent first circuit rows H in the first direction X smaller, thereby facilitating the matching connection between the first circuit groups 10 and the data lines 40 extending along the second direction Y.

[0077] It should be noted that in the second transition area A32, the spacing of different adjacent first circuit groups 10 in the first direction X can be the same or different, and the spacing can change linearly or exponentially, which is not limited in the embodiment of the present application.

[0078] In some optional embodiments, in the second transition area A32, the spacing between at least part of adjacent first circuit groups 10 is equal to or smaller than the spacing between adjacent driving circuits in the first circuit group 10, that is, part of the first circuit groups 10 in the second transition area A32 can be arranged adjacent to each other.

[0079] In some embodiments, in the second transition area A32, the minimum spacing of adjacent first circuit groups 10 in the first direction X is greater than the maximum spacing of adjacent first circuit groups 10 in the first direction X in the first transition area A31. In other words, in the second transition area A32, the spacing of any adjacent first circuit groups 10 in the first direction X is greater than the spacing of any adjacent first circuit groups 10 in the first direction X in the first transition area A31.

[0080] This design further optimizes the arrangement of the first circuit groups 10 in the transition area A3, so that the first circuit groups 10 in the first transition area A31 are arranged more compactly, the first circuit groups 10 in the second transition area A32 are arranged more dispersedly, and the displacement of adjacent first circuit rows H in the first direction X in the transition area A3 can be reduced, which is beneficial to the connection between the first circuit groups 10 and the data lines 40.

[0081] In some embodiments, as shown in Figure 8 and Figure 9 The plurality of first circuit groups 10 includes the first type of circuit groups 10a located at both ends of the first circuit row H and the second type of circuit groups 10b, and the distance between the first type of circuit groups 10a and the second area A2 in the first direction X is greater than the distance between the second type of circuit groups 10b and the second area A2. Among them, at least three first type of circuit groups 10a located in the second transition area A32 are located on the same straight line, and the extension direction of the straight line intersects the second direction Y.

[0082] Each first circuit row H includes at least a first circuit group 10a and a second circuit group 10b located at two ends, wherein the second circuit group 10b is located at a joint position of the transition region A3 and the second region A2. At least three first circuit groups 10a located in the second transition region A32 are located on a same straight line, and the at least three first circuit groups 10a are first circuit groups 10a located in different first circuit rows H, wherein the two closest first circuit groups 10a can be located in adjacent first circuit rows H or can be located in two first circuit rows H arranged at intervals.

[0083] The "at least three first circuit groups 10a located on a same straight line" mentioned in the embodiments of the present application means that the at least three first circuit groups 10a simultaneously overlap with the same straight line. Further optionally, the corresponding positions of any two first circuit groups 10a of the at least three first circuit groups 10a are connected, and the corresponding positions are located on the same straight line. For example, the centers of any two first circuit groups 10a of the at least three first circuit groups 10a are connected, and the centers are located on the same straight line. The embodiments of the present application do not limit the inclination angle of the straight line relative to the second direction Y. For example, the straight line can be inclined by 30°, 45° or 60° relative to the second direction Y.

[0084] The embodiments of the present application make the at least three first circuit groups 10a located on the same straight line, so that the displacement amount of the at least three first circuit rows H located in the second transition region A32 in the first direction X is consistent, thereby standardizing the arrangement of the plurality of first circuit groups 10 in the second transition region A32, and facilitating the data line 40 to pass through and be connected to the first circuit groups 10 located in the second transition region A32. Further optionally, each first circuit group 10a located in the second transition region A32 is located on the same straight line.

[0085] In some embodiments, as shown in Figure 8 and Figure 9 At least part of the second circuit groups 10b in the different first circuit rows H located in the second transition region A32 are located on a same arc segment.

[0086] The "at least part of the second circuit groups 10b in the different first circuit rows H located in the second transition region A32 are located on a same arc segment" mentioned in the embodiments of the present application means that the at least part of the second circuit groups 10b simultaneously overlap with the same arc segment. Further optionally, the corresponding positions of the at least part of the second circuit groups 10b are sequentially connected, and an arc segment can be obtained.

[0087] As can be seen from the foregoing, the second type circuit group 10b is located at the position where the transition area A3 meets the second area A2, and the position of the second type circuit group 10b determines the boundary position of the corresponding first circuit row H. On this basis, the embodiment of the present application sets at least part of the second type circuit group 10b in the second transition area A32 on the same arc segment, compared with the scheme that the second type circuit group 10b is located on the same straight line segment, the arc segment enables at least part of the first circuit group 10 to be arranged outward, thereby optimizing the arrangement of the first circuit group 10 in the second transition area A32, and enabling the first circuit group 10 in the second transition area A32 to be more dispersedly arranged.

[0088] In some embodiments, as shown in FIG. 2, the first type circuit group 10a in the first transition area A31 and the second type circuit group 10b in the second transition area A32 are arranged in a staggered manner. Figure 8 and Figure 9 As shown in FIG. 2, the included angle between the direction of the line connecting the first type circuit group 10a located in the second transition area A32 and closest to the first transition area A31 and the center of the first area A1 and the first direction X is α, and α satisfies: 30°≤α≤45°.

[0089] The size of the included angle α determines the relative sizes of the first transition area A31 and the second transition area A32. Specifically, if the included angle α is too large, the size of the first transition area A31 in the second direction Y is too large, and the size of the second transition area A32 in the second direction Y is too small, which easily leads to the fact that multiple first circuit groups 10 are closely arranged in the first transition area A31, and the close arrangement of too many first circuit groups 10 in the first transition area A31 easily increases the risk of interference between the first circuit groups 10, and easily causes display abnormalities.

[0090] If the included angle α is too small, the size of the second transition area A32 in the second direction Y is too large, and the size of the first transition area A31 in the second direction Y is too small. This leads to the fact that too many first circuit groups 10 are arranged too dispersedly, which is easily observed by the human eye, thereby adversely affecting the display effect.

[0091] Therefore, the embodiment of the present application sets the included angle α to 30°≤α≤45°, thereby reasonably regulating the sizes of the first transition area A31 and the second transition area A32, so as to optimize the arrangement mode of the multiple first circuit groups 10 in the transition area A3, while ensuring the use reliability of the display panel, and reducing the influence of the first circuit group 10 on the display effect. Exemplarily, the included angle α is one of 30°, 35°, 40° and 45°, or other angles between 30° and 45°, which are not limited in the present application.

[0092] In addition, in combination with the accompanying drawings, Figure 2In other words, the part of the selection signal line 20 near the first area A1 is arranged around the first area A1. On this basis, if the included angle a is set too large, the part of the first circuit group 10 in the second transition area A32 is prone to overlapping and interfering with the part of the selection signal line 20 arranged around the first area A1, thereby easily causing display abnormalities and other problems. If the included angle a is set too small, the second transition area A32 is too small in the second direction Y, and the number of the first circuit groups 10 that can be accommodated is too small, which is prone to causing space waste.

[0093] Therefore, in the embodiments of the present application, the included angle a is set to 30°≤a≤45°, which can optimize the arrangement of the first circuit group 10 while reducing the probability of interference between part of the first circuit group 10 and part of the selection signal line 20, and improving the reliability of the display panel.

[0094] In some embodiments, as shown in FIG. 1, the selection signal line 20 extends along the first direction X. In the transition area A3, the extension length of the jth selection signal line 20j is greater than that of the ith selection signal line 20i, L1>L2. Figures 2 to 4

[0095] The selection signal line 20 extends along the first direction X. It should be noted that the extension along the first direction X here means that the selection signal line 20 has a tendency to extend along the first direction X, rather than being a straight line structure that extends along the first direction X as a whole. The selection signal line 20 can be a curve or a polyline structure, and the local extension direction thereof can intersect the first direction X.

[0096] Since the extension length of the jth selection signal line 20j is greater than that of the ith selection signal line 20i, and the extension length is often positively correlated with the load of the selection signal line 20 itself. Therefore, the load of the jth selection signal line 20j will be greater than that of the ith selection signal line 20i, thereby causing the transmission signal effects of the two to be different, and easily causing display abnormalities and other problems.

[0097] On this basis, in the embodiments of the present application, the size L1 of the first direction X between the adjacent first circuit groups 10 in the ith first circuit row Hi is set to be greater than the size L2 of the first direction X between the adjacent first circuit groups 10 in the jth first circuit row Hj, so that the lateral capacitance in the ith first circuit row Hi is greater than that in the jth first circuit row Hj, and then the ith selection signal line 20i is affected by a greater lateral capacitance than the jth selection signal line 20j, thereby optimizing the load difference between the ith selection signal line 20i and the jth selection signal line 20j, making the loads of the two tend to be consistent, ensuring that the transmission signal effects of the two are basically consistent, and reducing the risk of display abnormalities. ​

[0098] In some embodiments, the plurality of first circuit groups 10 are symmetrically distributed about a first virtual straight line Z, wherein the first virtual straight line Z passes through the center of the first area A1 and extends along a direction parallel to the second direction Y.

[0099] In combination Figure 8 , the transition area A3 is arranged with a plurality of first circuit groups 10 on the left side of the first virtual straight line Z, and a plurality of first circuit groups 10 are also arranged on the right side of the first virtual straight line Z, and the plurality of first circuit groups 10 on both sides of the first virtual straight line Z are symmetrically distributed about the first virtual straight line Z. This design enables the plurality of first circuit groups 10 to be evenly distributed on both sides of the first area A1 in the first direction X, which is conducive to optimizing the arrangement of the first circuit groups 10 in the transition area A3.

[0100] In some embodiments, referring to Figure 8 and Figure 10 , the display panel further comprises a second circuit group 30 located in the second area A2, the first circuit group 10 comprises a plurality of first driving circuits 11, the second circuit group 30 comprises a plurality of second driving circuits 31, and the number of first driving circuits 11 in a single first circuit group 10 is less than the number of second driving circuits 31 in a single second circuit group 30.

[0101] The plurality of first driving circuits 11 in the first circuit group 10 are used to drive the light emitting units located in the transition area A3 or in the first area A1 to emit light, and the plurality of second driving circuits 31 in the second circuit group 30 are used to drive the light emitting units located in the second area A2 to emit light. Further, the plurality of first driving circuits 11 are arrayed with each other to form the first circuit group 10, and the plurality of first circuit groups 10 are repeatedly translated in the transition area A3, wherein the arrangement of the plurality of first driving circuits 11 in different first circuit groups 10 is the same as each other.

[0102] In addition, the plurality of light emitting units can constitute a pixel repeating unit, and the plurality of pixel repeating units are repeatedly translated to form a corresponding pixel arrangement structure. On this basis, a single first circuit group 10 can be used to drive the plurality of light emitting units in a single pixel repeating unit to emit light. The same applies to the second circuit group 30, and the embodiments of the present application will not be described here.

[0103] Generally, in order to improve the display effect of the display panel, the size of the transition area A3 needs to be reduced as much as possible to reduce the influence of the transition area A3 on the display effect. On this basis, in order to reduce the size of the transition area A3, the size of the first circuit group 10 is limited and reduced in the embodiments of the present application, and the number of the first driving circuit 11 in a single first circuit group 10 is set to be less than the number of the second driving circuit 31 in a single second circuit group 30, so that the size of a single first circuit group 10 is less than the size of a single second circuit group 30, thereby achieving the purpose of reducing the space of the transition area A3 and improving the display effect.

[0104] The specific number of the first driving circuit 11 in a single first circuit group 10 and the specific number of the second driving circuit 31 in a single second circuit group 30 are not limited in the embodiments of the present application. Alternatively, the number of columns of the first driving circuit 11 in a single first circuit group 10 in the first direction X can be less than the number of columns of the second driving circuit 31 in a single second circuit group 30 in the first direction X, or the number of rows of the first driving circuit 11 in a single first circuit group 10 in the second direction Y can be less than the number of rows of the second driving circuit 31 in a single second circuit group 30 in the second direction Y.

[0105] In some embodiments, as shown in Figure 10 , the number of rows of the second driving circuit 31 in a single second circuit group 30 in the second direction Y is the same as the number of rows of the first driving circuit 11 in a single first circuit group 10 in the second direction Y. Further, the number of columns of the first driving circuit 11 in a single first circuit group 10 in the first direction X can be less than the number of columns of the second driving circuit 31 in a single second circuit group 30 in the first direction X.

[0106] The size of the first circuit group 10 in the second direction Y is often determined by the number of rows of the first driving circuit 11 in the second direction Y, and the size of the second circuit group 30 in the second direction Y is often determined by the number of rows of the second driving circuit 31 in the second direction Y. Therefore, the number of rows of the driving circuit in the first circuit group 10 is the same as that in the second circuit group 30, that is, the size of the first circuit group 10 and the second circuit group 30 in the second direction Y is relatively close. In this way, during the design stage of the display panel, the rows where the first circuit group 10 and the second circuit group 30 are located can be aligned and arranged in the second direction Y, thereby optimizing the arrangement mode of the first circuit group 10 and the second circuit group 30 as a whole.

[0107] In some embodiments, please refer to Figure 8 and Figure 10 , the display panel further comprises a data line 40 across the transition area A3 in the second direction Y, and the number of the second driving circuit 31 connected by the same data line 40 in a single second circuit group 30 is greater than the number of the first driving circuit 11 connected by the same data line 40 in a single first circuit group 10.Figure 10 In some embodiments, the connections of the data lines 40 to the first driving circuits 11 and the connections of the data lines 40 to the second driving circuits 31 are schematically shown by black dots.

[0108] The data lines 40 extend in the second direction Y and are used to transmit data signals, and some of the data lines 40 pass through both the first circuit group 10 and the second circuit group 30. As mentioned above, the number of the first driving circuits 11 in a single first circuit group 10 is less than the number of the second driving circuits 31 in a single second circuit group 30. If the number of the second driving circuits 31 connected to a single data line 40 in a single second circuit group 30 is equal to the number of the first driving circuits 11 connected to a single data line 40 in a single first circuit group 10, too many data lines 40 cannot be electrically connected to the first driving circuits 11, and thus are stacked between the adjacent first circuit groups 10, which is not conducive to the arrangement of the data lines 40 and can cause a large load difference between different signal lines.

[0109] To address this, the number of the first driving circuits 11 to which a data line 40 is connected is adjusted in some embodiments, such that the number of the second driving circuits 31 connected to a single data line 40 in a single second circuit group 30 is greater than the number of the first driving circuits 11 connected to a single data line 40 in a single first circuit group 10. In combination with the above-mentioned adjustment of the number of the second driving circuits 31, more data lines 40 can be electrically connected to the first driving circuits 11, and the number of the data lines 40 that cannot be electrically connected to the first driving circuits 11 is reduced, thereby reducing the number of the data lines 40 between the adjacent first circuit groups 10 and optimizing the arrangement of the data lines 40. Figure 8 Figure 8 For example, as shown in FIG. 1, a first circuit group 10 includes four first driving circuits 11, and a second circuit group 30 includes eight second driving circuits 31. In this case, a single data line 40 is connected to two second driving circuits 31 in the same column in the second circuit group 30 and to one first driving circuit 11 in the first circuit group 10.

[0110] This design can ensure that more data lines 40 can be connected to the first driving circuits 11, reduce the number of the data lines 40 that cannot be connected to the first driving circuits 11, and thereby reduce the number of the data lines 40 between the adjacent first circuit groups 10, so as to optimize the arrangement of the data lines 40.

[0111] In some embodiments, as shown in FIG. 1, at least part of the different data lines 40 are used to connect a plurality of first driving circuits 11 in the same column in the second direction Y. Figure 10

[0112] ​​Generally, a single data line 40 is connected to all the second driving circuits 31 in the same column. Since the number of the second driving circuits 31 connected to a single data line 40 in a single second circuit group 30 is less than the number of the first driving circuits 11 connected to a single data line 40 in a single first circuit group 10, a single data line 40 is only connected to part of the first driving circuits 11 in the same column. On this basis, other first driving circuits 11 in the same column need to be electrically connected by other data lines 40 to realize the transmission of data signals.

[0113] In some optional embodiments, a plurality of data lines 40 arranged adjacently are used to connect a plurality of first driving circuits 11 in the same column. This is conducive to reducing the layout difficulty between the plurality of data lines 40 and the plurality of first driving circuits 11, reducing the risk of cross misplacement of different data lines 40, and ensuring the reliability of signal transmission between different data lines 40.

[0114] The specific connection relationship between the data line 40 and the plurality of first driving circuits 11 in the same column is not limited in the embodiments of the present application. For example, a single data line 40 can be connected to a plurality of adjacent first driving circuits 11 in the same column at the same time.

[0115] Or in another embodiment, at least part of the first driving circuits 11 connected by a single data line 40 are provided with other first driving circuits 11. That is, adjacent first driving circuits 11 in the same column are driven and controlled by different data lines 40.

[0116] This can reduce the risk of abnormal data signal transmission caused by excessive connection of first driving circuits 11 in a local position of the data line 40, which leads to excessive load in the local position. Further, this design also optimizes the connection mode between the plurality of data lines 40 and the plurality of first driving circuits 11 in the same column, reduces the risk of signal crosstalk between adjacent first driving circuits 11, and improves the reliability of data signal transmission.

[0117] In some embodiments, please refer to Figure 10 and Figure 11 The number of data lines 40 is a plurality, the plurality of data lines 40 includes a first data line 41 and a second data line 42 arranged adjacently, and the number of first driving circuits 11 is a plurality, the plurality of first driving circuits 11 includes a first type of driving circuit 11a connected to the first data line 41 and a second type of driving circuit 11b connected to the second data line 42.

[0118] The first type of driving circuit 11a includes a first connecting portion B1 electrically connected to the first data line 41, and the second type of driving circuit 11b includes a second connecting portion B2 electrically connected to the second data line 42. In the thickness direction of the display panel, the projection of the first connecting portion B1 and the projection of the second connecting portion B2 are at least partially located between the first data line 41 and the second data line 42.

[0119] The first data line 41 and the second data line 42 are two adjacent data lines 40, and are used to connect a plurality of first driving circuits 11 located in the same column in the first direction X. In other words, the first type of driving circuit 11a and the second type of driving circuit 11b are two first driving circuits 11 in the same column.

[0120] The first type of driving circuit 11a is electrically connected to the first data line 41 through the first connecting portion B1, and the connection mode includes but is not limited to via connection; the second type of driving circuit 11b is electrically connected to the second data line 42 through the second connecting portion B2, and the connection mode includes but is not limited to via connection. Generally, the first connecting portion B1 and the second connecting portion B2 are respectively arranged corresponding to the first data line 41 and the second data line 42, and because the first data line 41 and the second data line 42 have a certain spacing in the first direction X, the first connecting portion B1 and the second connecting portion B2 will have a large misalignment in the first direction X. This results in a large difference in structure between the first type of driving circuit 11a and the second type of driving circuit 11b, thereby increasing the design difficulty of the plurality of first driving circuits 11, and also increasing the preparation difficulty of the plurality of first driving circuits 11.

[0121] In order to reduce the preparation difficulty of the plurality of first driving circuits 11, the structure of different first driving circuits 11 is adjusted in the embodiments of the present application. Taking the first type of driving circuit 11a and the second type of driving circuit 11b as an example, the projections of the first connecting portion B1 and the second connecting portion B2 in the thickness direction are located between the projections of the first data line 41 and the second data line 42, so that the misalignment of the first connecting portion B1 and the second connecting portion B2 in the first direction X can be reduced, thereby reducing the structural difference between the structure for connecting the first connecting portion B1 in the first type of driving circuit 11a and the structure for connecting the second connecting portion B2 in the second type of driving circuit 11b, so that the structures of the first type of driving circuit 11a and the second type of driving circuit 11b can be as consistent as possible, thereby reducing the preparation difficulty of the plurality of first driving circuits 11.

[0122] In some embodiments, in the thickness direction of the display panel, the projection of the first connecting portion B1 at least partially overlaps the projection of the first data line 41.

[0123] The first data line 41 is electrically connected with the first driving circuit 11a through the first connecting part B1. In order to improve the connection reliability between the first data line 41 and the first driving circuit 11a, the projection of the first connecting part B1 at least partially overlaps the projection of the first data line 41. For example, the projection of the first connecting part B1 in the thickness direction can include a long strip structure extending along the first direction X. In this way, the projection of the first connecting part B1 can have more overlap with the projection of the first data line 41, thereby facilitating the improvement of the electrical conduction reliability between the two and improving the data signal transmission reliability.

[0124] Of course, in other optional embodiments, the projection of the second connecting part B2 in the thickness direction of the display panel can also at least partially overlap the projection of the second data line 42, which will not be described hereinafter.

[0125] In some embodiments, referring to Figure 12 The number of second driving circuits 31 in a single second circuit group 30 in the second direction Y is the same as the number of first driving circuits 11 in a single first circuit group 10 in the second direction Y. The number of second driving circuits 31 connected by a single data line 40 in a single second circuit group 30 is equal to the number of first driving circuits 11 connected by a single data line 40 in a single first circuit group 10.

[0126] Since the number of rows of first driving circuits 11 in the first circuit group 10 is the same as the number of rows of second driving circuits 31 in the second circuit group 30, and the number of first driving circuits 11 in the first circuit group 10 is less than the number of second driving circuits 31 in the second circuit group 30, the number of columns of first driving circuits 11 in the first circuit group 10 in the first direction X is less than the number of columns of second driving circuits 31 in the second circuit group 30 in the first direction X.

[0127] On this basis, the number of second driving circuits 31 connected by a single data line 40 in a single second circuit group 30 is set to be equal to the number of first driving circuits 11 connected by a single data line 40 in a single first circuit group 10. In this way, the connection relationship of the data line 40 relative to the first driving circuit 11 can be consistent with the connection relationship of the data line 40 relative to the second driving circuit 31, the data line 40 can extend in the same way at the position of the first circuit group 10 as at the position of the second circuit group 30, and the structure of the first driving circuit 11 can be set to be the same as the structure of the second driving circuit 31, thereby further reducing the difficulty of manufacturing the first driving circuit 11.

[0128] In some embodiments, referring to Figure 13The plurality of data lines 40 includes a third data line 43. In the thickness direction of the display panel, a part of the structure of the third data line 43 is projected in the projection of the first circuit group 10, and the third data line 43 is arranged to be insulated from the first driving circuit 11. And / or, as shown in Figure 12 in the thickness direction, a part of the structure of the third data line 43 is projected between the projections of two adjacent first circuit groups 10.

[0129] From the foregoing, it can be seen that the number of first driving circuits 11 in the first circuit group 10 is less than the number of second driving circuits 31 in the second circuit group 30, and the number of second driving circuits 31 connected by a part of the data lines 40 in a single second circuit group 30 is equal to the number of first driving circuits 11 connected by a part of the data lines 40 in a single first circuit group 10, which will cause some data lines 40, such as the third data line 43, to be unable to be connected to the first driving circuit 11.

[0130] In order to meet the extension needs of the third data line 43, the third data line 43 is arranged between the projections of two first circuit groups 10 or between the projections of two first driving circuits 11 in the first circuit group 10 in the embodiments of the present application, so as to meet the extension needs of the third data line 43 while meeting the need of arranging the third data line 43 to be insulated from the first driving circuit 11.

[0131] It should be noted that when the third data line 43 is arranged between two adjacent first circuit groups 10, the capacitance between the third data line 43 and the first driving circuit group 11 due to overlapping can be reduced, thereby reducing the load of the third data line 43. When a part of the structure of the third data line 43 is projected in the projection of the first circuit group 10 and arranged to be insulated from the first driving circuit 11, this design can make the arrangement of the data line 40 more compact, thereby saving space and reducing the capacitance difference between the third data line 43 and other data lines 40, which is conducive to improving display uniformity.

[0132] In addition, when a part of the structure of the third data line 43 is projected in the projection of the first circuit group 10, the projection of the third data line 43 can overlap the first driving circuit 11 or not overlap the first driving circuit 11, and the embodiments of the present application do not limit this.

[0133] In some optional embodiments, please refer to Figure 14The second circuit group 30 includes eight second drive circuits 31 arranged in two rows and four columns. The first circuit group 10 includes six first drive circuits 11 arranged in two rows and three columns. On this basis, part of the data lines 40 are connected to two second drive circuits 31 in the same column in the second circuit group 30 and connected to two first drive circuits 11 in the same column in the first circuit group 10. The third data line 43 is connected to two second drive circuits 31 in the same column in the second circuit group 30 and at least partially projects between the projections of the two first drive circuits 11 in the first circuit group 10. This design can make most of the data lines 40 connected to the first drive circuits 11 and the second drive circuits 31 at the same time, so that the load difference between most of the data lines 40 is small, thereby improving the display uniformity of the display panel and improving the display reliability.

[0134] It should be noted that, Figure 14 The third data line 43 is schematically shown in the first circuit group 10, but in other optional embodiments, the orthographic projection of the third data line 43 can be located in the first circuit group 10, and the orthographic projection of the third data line 43 can be arranged to overlap the first drive circuit 11 or not overlap the first drive circuit 11, which is not limited in the embodiments of the application.

[0135] In some embodiments, as shown in Figure 12 The size of the first circuit group 10 in the first direction X is smaller than the size of the second circuit group 30 in the first direction X.

[0136] Since the size of the transition area A3 is small, in order to meet the placement needs of the plurality of first circuit groups 10, the size of the first circuit group 10 is limited and reduced, so that the size of the first circuit group 10 in the first direction X is smaller than the size of the second circuit group 30 in the first direction X. The size reduction method has many kinds, for example, the number of first drive circuits 11 in the first circuit group 10 can be reduced, or the size of a single first drive circuit 11 can be reduced.

[0137] In order to meet the placement needs of the first circuit group 10 in the transition area A3, the size of the first circuit group 10 is limited and reduced, so that the size of the first circuit group 10 in the first direction X is smaller than the size of the second circuit group 30 in the first direction X, thereby more first circuit groups 10 can be arranged in the transition area A3 to better realize the full-screen display.

[0138] In other optional embodiments, the size of the first circuit group 10 in the second direction Y is smaller than the size of the second circuit group 30 in the second direction Y.

[0139] In some embodiments, in a single first circuit group 10, the distance between adjacent first driving circuits 11 in the first direction X is less than the distance between adjacent second driving circuits 31 in the first direction X in a single second circuit group 30.

[0140] As can be seen from the foregoing, the size of the first circuit group 10 needs to be reduced. Based on this, the embodiment of this application reduces the spacing between adjacent first driving circuits 11 in the first circuit group 10 in the first direction X, making it smaller than the distance between adjacent second driving circuits 31 in the second circuit group 30 in the first direction X. This reduces the size of the first circuit group 10 in the first direction X, which helps to arrange more first circuit groups 10 in the transition area A3 to better achieve the full-screen display effect.

[0141] Of course, in some other embodiments, the distance between adjacent first driving circuits 11 in the second direction Y in a single first circuit group 10 may be less than the distance between adjacent second driving circuits 31 in the second direction Y in a single second circuit group 30. This application embodiment will not elaborate further on this.

[0142] In some embodiments, such as Figure 2 As shown, the j-th selection signal line 20j includes a first part 21 and a second part 22 electrically connected. There are two first parts 21, located on both sides of the first region A1 in the first direction X. The second part 22 is used to connect the two first parts 21 and is arranged around the first region A1. Along the thickness direction of the display panel, the projection of the first part 21 at least partially overlaps with the projection of the first circuit group 10, and the projection of the second part 22 is offset from the projection of the first circuit group 10.

[0143] The first part 21 extends along the first direction X, and two first parts 21 are spaced apart in the first direction X. Due to the existence of the first region A1, the two first parts 21 cannot be connected by a straight line, but need to be connected by a second part 22 surrounding the first region A1. Typically, the shape of the second part 22 matches the outline shape of the first region A1. For example, if the first region A1 is a circular structure, the second part 22 may include an arc structure.

[0144] Since the second part 22 needs to be set around the first area A1, the existence of the second part 22 will increase the overall extension length of the j-th gating signal line 20j, making the extension length of the j-th gating signal line 20j greater than the extension length of the i-th gating signal line 20i, resulting in the load of the j-th gating signal line 20j being greater than the load of the i-th gating signal line 20i.

[0145] On this basis, the embodiment of the present application sets the size L1 in the first direction X between the adjacent first circuit groups 10 in the first circuit row Hi in the i-th row to be greater than the size L2 in the first direction X between the adjacent first circuit groups 10 in the first circuit row Hj in the j-th row. This makes the lateral capacitance in the first circuit row H in the i-th row greater than the lateral capacitance in the first circuit row H in the j-th row, and further causes the i-th selection signal line 20i to be affected by a greater lateral capacitance than the j-th selection signal line 20j, thereby optimizing the load difference between the i-th selection signal line 20i and the j-th selection signal line 20j, making the loads of the two tend to be consistent, ensuring that the effects of the transmitted signals are substantially consistent, and reducing the risk of display abnormalities.

[0146] In some embodiments, referring to Figure 15 and Figure 16 , the display panel further comprises a first light emitting unit 50 located in at least one of the first area A1 and the transition area A3, and the first circuit group 10 comprises a plurality of first driving circuits 11, and at least part of the first driving circuits 11 are used to drive the plurality of first light emitting units 50 to emit light. Wherein Figure 15 is a structural schematic view of the first driving circuit 11 driving the first light emitting unit 50 located in the transition area A3, Figure 16 is a structural schematic view of the first driving circuit 11 driving the first light emitting unit 50 located in the first area A1.

[0147] Since the first circuit group 10 is located in the transition area A3, in order to reduce the number of first circuit groups 10 as much as possible to achieve the effect of reducing the size of the transition area A3. The embodiment of the present application uses at least part of the first driving circuits 11 to drive the plurality of first light emitting units 50 to emit light, thereby achieving the effect of "one drive multiple", so that a small number of first driving circuits 11 can drive a larger number of first light emitting units 50 to emit light, thereby meeting the light emitting needs of a larger number of first light emitting units 50. Exemplarily, at least part of the first driving circuits 11 are used to drive two first light emitting units 50 to emit light.

[0148] It should be noted that for the second circuit group 30, the second driving circuit 31 inside it can only drive one light emitting unit located in the second area A2, that is, the second driving circuit is in a "one-to-one" driving mode. Therefore, even if the number of first driving circuits 11 in the first circuit group 10 is less than the number of second driving circuits 31 in the second circuit group 30, the number of light emitting units that can be driven by the first circuit group 10 can be greater than or equal to the number of light emitting units that can be driven by the second circuit group 30. This can reduce the size of the space occupied by all the first circuit groups 10 as much as possible, thereby reducing the size of the transition area A3 and improving the display effect of the display panel.

[0149] In some optional embodiments, the first circuit group 10 includes four first driving circuits 11 arranged in two rows and two columns, wherein the two first driving circuits in the first row are respectively used for driving the red light emitting units and the blue light emitting units to emit light, and the two first driving circuits in the second row are both used for driving the green light emitting units to emit light.

[0150] The second circuit group 30 includes eight second driving circuits 31 arranged in two rows and four columns, wherein the four second driving circuits in the first row are sequentially used for driving the red light emitting units, the green light emitting units, the blue light emitting units and the green light emitting units to emit light, and the four second driving circuits in the second row are sequentially used for driving the blue light emitting units, the green light emitting units, the red light emitting units and the green light emitting units to emit light.

[0151] In some embodiments, as shown in Figure 15 and Figure 16 The display panel further includes a first conductive part 61 and a second conductive part 62, the first conductive part 61 is connected to the plurality of first light emitting units 50, and the second conductive part 62 is connected to the first conductive part 61 and the first driving circuit 11.

[0152] The first light emitting unit 50 generally includes a plurality of film layers, such as an anode layer, a carrier transport layer, a light emitting layer, an electron transport layer, and a cathode layer. The “first conductive part 61 is connected to the plurality of first light emitting units 50” mentioned in the embodiments of the present application means that the first conductive part 61 is connected to the anodes of the plurality of first light emitting units 50 at the same time.

[0153] The second conductive part 62 is connected to the first conductive part 61 and the first driving circuit 11, and the first driving circuit 11 can transmit signals to the first conductive part 61 through the second conductive part 62, and transmit the signals to the plurality of first light emitting units 50 at the same time through the first conductive part 61, so as to realize the driving control of the plurality of first light emitting units 50. The materials of the first conductive part 61 and the second conductive part 62 are not limited in the embodiments of the present application. For example, the first conductive part 61 and the second conductive part 62 can both include metal materials.

[0154] It should be noted that in some optional embodiments, one end of the second conductive part 62 is directly connected to the anode of the first light emitting unit 50, and since the first conductive part 61 is connected to the anodes of the plurality of first light emitting units 50 at the same time, the second conductive part 62 can be connected to the first conductive part 61 through the anode, and connected to the anodes of the plurality of first light emitting units 50 through the first conductive part 61. Alternatively, one end of the second conductive part 62 can also be directly connected to the first conductive part 61, so as to realize the electrical connection with the anodes of the plurality of first light emitting units 50.

[0155] The first conductive part 61 is used to connect the plurality of first light emitting units 50, and the first conductive part 61 and the second conductive part 62 are used to simultaneously drive and control the plurality of first light emitting units 50 by the single first driving circuit 11, so as to realize the effect that the single first driving circuit 11 controls the plurality of first light emitting units 50.

[0156] In some embodiments, the single first conductive part 61 is connected to the plurality of first light emitting units 50 for emitting light of the same color.

[0157] As can be seen from the foregoing, the single first driving circuit 11 can simultaneously control the plurality of first light emitting units 50 through the first conductive part 61 and the second conductive part 62. In order to reduce the risk of display abnormalities, the single first conductive part 61 is connected to the plurality of first light emitting units 50 for emitting light of the same color, so that the plurality of first light emitting units 50 controlled by the single first driving circuit 11 are the first light emitting units 50 for emitting light of the same color. In this way, the risk of mutual influence between the first light emitting units 50 of different light emitting colors can be reduced, and the display reliability can be improved.

[0158] In some embodiments, the first circuit group 10 includes a plurality of rows of first driving circuits 11 in the second direction Y, and the first conductive part 61 and the second conductive part 62 are connected at the connection end D. In the single first circuit group 10, the arrangement order of the first driving circuits 11 in different rows in the second direction Y is the same as the arrangement order of the corresponding connection ends D in the second direction Y.

[0159] The plurality of rows of first driving circuits 11 all need to be connected to the corresponding first conductive part 61 through the second conductive part 62. In combination with the drawings, in the single first circuit group 10, the plurality of rows of first driving circuits 11 are arranged side by side from top to bottom. If the plurality of connection ends D corresponding to the plurality of rows of first driving circuits 11 are arranged from bottom to top, the first conductive parts 61 connected by different first driving circuits 11 are likely to cross and interfere with each other, thereby causing problems such as signal crosstalk, which is not conducive to the driving control of the first driving circuit 11 on the first light emitting unit 50.

[0160] Therefore, in the embodiments of the present application, the arrangement order of the first driving circuits 11 in different rows in the second direction Y is the same as the arrangement order of the corresponding connection ends D in the second direction Y, so as to reduce the risk of cross interference of different first conductive parts 61 and ensure the reliability of signal transmission in the first conductive part 61.

[0161] In some embodiments, at least one of the first conductive part 61 and the second conductive part 62 comprises a transparent material.

[0162] Since the first drive circuit 11 is located in the transition region A3, and the first light emitting unit 50 is located in the transition region A3 or the first region A1, the first conductive part 61 and the second conductive part 62 for connecting the first drive circuit 11 and the first drive unit can also be partially located in the first region A1.

[0163] In order to improve the light transmittance of the first region A1 and meet the light sensing needs of the display panel, at least one of the first conductive part 61 and the second conductive part 62 is provided with a transparent material in the embodiments of the present application. The presence of the transparent material can improve the transmittance of the corresponding region while meeting the electrical conduction needs, thereby meeting the light sensing needs. For example, the transparent material includes at least one of indium tin oxide (ITO), indium zinc oxide, silver-doped indium tin oxide, and silver-doped indium zinc oxide.
