[0003] This application relates to the field of display technology, specifically to a display panel and display device. Background Technology

[0004] In related technologies, display panels typically include a gate driving circuit located in the non-display area and pixels located in the display area. The gate driving circuit is connected to the pixels via connecting lines located in the non-display area. However, the connecting lines and the gate driving circuit occupy a large amount of space in the non-display area, which is not conducive to the narrow bezel design of the display panel. Invention Overview

[0005] This application provides a display panel and a display device, aiming to solve the problem that display panels in the related art are difficult to achieve narrow bezels.

[0006] On one hand, this application provides a display panel having a display area and a non-display area located on at least one side of the display area. The display panel includes: a substrate, a plurality of light-emitting units disposed on the substrate, a plurality of shared pixel circuits disposed on the substrate and located in the display area, and a gate driving circuit disposed on the substrate and located in the non-display area. The light-emitting units are located in the display area and are arranged in an array. Each light-emitting unit includes a plurality of light-emitting devices with different light-emitting colors. The gate driving circuit is electrically connected to the plurality of shared pixel circuits through a plurality of connecting lines. Each shared pixel circuit is electrically connected to a plurality of light-emitting devices in the plurality of light-emitting units. For a light-emitting device in the plurality of light-emitting units that is closer to the gate driving circuit, the shared pixel circuit is disposed on the side of the light-emitting device that is away from the gate driving circuit and is electrically connected to the light-emitting device. The connecting lines are at least partially located in the display area.

[0007] On the other hand, embodiments of this application also provide a display device, which includes a display panel having a display area and a non-display area located on at least one side of the display area. The display panel includes: a substrate, a plurality of light-emitting units disposed on the substrate, a plurality of shared pixel circuits disposed on the substrate and located in the display area, and a gate driving circuit disposed on the substrate and located in the non-display area. The light-emitting units are located in the display area and are arranged in an array. Each light-emitting unit includes a plurality of light-emitting devices with different light-emitting colors. The gate driving circuit is electrically connected to the plurality of shared pixel circuits through a plurality of connecting lines. Each shared pixel circuit is electrically connected to a plurality of light-emitting devices in the plurality of light-emitting units. For a light-emitting device in the plurality of light-emitting units that is close to the gate driving circuit, the shared pixel circuit is disposed on the side of the light-emitting device that is away from the gate driving circuit and is electrically connected to the light-emitting device. The connecting lines are at least partially located in the display area. Beneficial effects

[0008] In the display panel provided in this application embodiment, since each shared pixel circuit drives multiple light-emitting devices, the number of pixel circuits used to drive the light-emitting devices can be reduced, allowing at least a portion of the connecting lines to be arranged in the space corresponding to the light-emitting devices near the gate driving circuit. In other words, the connecting lines originally located in the non-display area are at least partially transferred to the display area, thereby narrowing the width of the non-display area and achieving a narrow bezel design for the display panel.

[0022] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The described technical solutions are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0023] In the description of this application, it should be understood that the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words mean two or more, unless otherwise expressly defined.

[0024] The use of “configured to” in this application implies open and inclusive language, which does not preclude the applicability to or configuration of devices to perform additional tasks or steps. Furthermore, the use of “based on” implies openness and inclusivity, because processes, steps, calculations, or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0025] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application.

[0026] The various embodiments of this application are similar, and features from different embodiments and / or different examples can be combined with each other.

[0027] In related technologies, as shown in Figure 1, a display panel 100' typically includes a gate driving circuit 10' located in a non-display area NA' and pixels 20' located in the display area AA'. The gate driving circuit 10' is electrically connected to the pixels 20' via a connecting line 30' located in the non-display area NA'. Each pixel 20' includes a light-emitting device and a driving circuit 21' electrically connected to the light-emitting device. The connecting line 30' is electrically connected to the driving circuit 21', thereby inputting a control signal to the driving circuit 21'.

[0028] However, since the connecting line 30' and the gate driving circuit 10' both occupy a certain amount of space, the design size of the non-display area NA' is relatively large, which is not conducive to the narrow bezel design of the display panel 100'.

[0029] Based on this, some embodiments of this application provide a display panel, as shown in Figures 2 and 3, wherein the display panel 100 has a display area AA and a non-display area NA located on at least one side of the display area AA.

[0030] The display panel 100 includes a substrate and a plurality of light-emitting units 10 disposed on the substrate. The plurality of light-emitting units 10 are located within a display area AA and are arranged in an array. For example, the plurality of light-emitting units 10 are arranged along a first direction X to form a column of light-emitting units 10, and the multiple columns of light-emitting units 10 are spaced apart along a second direction Y, wherein the second direction Y and the first direction X intersect each other. In this example, the first direction X and the second direction Y may be perpendicular to each other.

[0031] Each light-emitting unit 10 includes multiple light-emitting devices 11 that emit different colors. As an example, each light-emitting unit 10 includes a red light-emitting device, a green light-emitting device, and a blue light-emitting device, so that each light-emitting unit 10 emits colored light, thereby realizing the color display of the display panel 100.

[0032] The display panel 100 also includes a gate driving circuit 20 and a plurality of shared pixel circuits 121 disposed on the substrate. The gate driving circuit 20 can be a GOA (Gate On Array) circuit. The gate driving circuit 20 is located in the non-display area NA, and the plurality of shared pixel circuits 121 are all located in the display area AA. The gate driving circuit 20 is electrically connected to the plurality of shared pixel circuits 121 via multiple connecting lines 21. To better illustrate the connecting lines 21, the connecting lines indicated by the reference numeral 21 are highlighted in bold in Figure 2.

[0033] Each shared pixel circuit 121 is electrically connected to a plurality of light-emitting devices 11 in a plurality of light-emitting units 10. For a light-emitting device 11 in a plurality of light-emitting units 10 that is closer to the gate driving circuit 20, the shared pixel circuit 121 is disposed on the side of the light-emitting device 11 away from the gate driving circuit 20 and is electrically connected to the light-emitting device 11, with the connection line 21 at least partially located in the display area AA.

[0034] The light-emitting device 11 closest to the gate driving circuit 20 among the multiple light-emitting units 10 can be referred to as the selected light-emitting device 110. The selected light-emitting device 110 is the light-emitting device 11 closest to the gate driving circuit 20 along the second direction Y. The common pixel circuit 121 is disposed on the side of the selected light-emitting device 110 away from the gate driving circuit 20 and is electrically connected to the selected light-emitting device 110. In this way, multiple light-emitting devices 11 can be driven simultaneously by the common pixel circuit 121. At the same time, at least a portion of the connecting line 21 is arranged in the space of the display area AA by utilizing the space corresponding to the selected light-emitting device 110. This can narrow the width of the non-display area NA, thereby realizing the narrow bezel design of the display panel 100.

[0035] Therefore, for the display panel 100 provided in this application embodiment, since each shared pixel circuit 121 drives multiple light-emitting devices 11, the number of pixel circuits used to drive the light-emitting devices 11 can be reduced, allowing at least a portion of the connecting line 21 to be arranged in the space corresponding to the light-emitting device 11 near the gate driving circuit 20. In other words, the connecting line 21 originally located in the non-display area NA is at least partially transferred to the display area AA, thereby narrowing the width of the non-display area NA and realizing the narrow bezel design of the display panel 100.

[0036] In some embodiments, as shown in FIG2 and FIG3, a plurality of light-emitting units 10 electrically connected to the common pixel circuit 121 include a first light-emitting unit 101 near the gate driving circuit 20 and a second light-emitting unit 102 located on the side of the first light-emitting unit 101 away from the gate driving circuit 20, and the common pixel circuit 121 is located in the region where the second light-emitting unit 102 is located.

[0037] This arrangement allows the shared pixel circuit 121 to be relatively far from the gate driving circuit 20, thereby facilitating the use of the area corresponding to the light-emitting device 11 on the side closer to the gate driving circuit 20 for arranging at least a portion of the connecting lines 21.

[0038] It is worth noting that the area where the second light-emitting unit 102 is located refers to the area corresponding to the second light-emitting unit 102 along the thickness direction of the display panel 100. The area where the second light-emitting unit 102 is located is not limited to the area defined by each light-emitting device 11 itself, but also includes the area between two adjacent light-emitting devices 11.

[0039] In some examples, the connecting line 21 is positioned within the display area AA.

[0040] In other examples, the connecting lines 21 are all located within the display area AA. For instance, based on the example where the connecting lines 21 are all located within the display area AA, the gate driving circuit 20 can be at least partially located within the display area AA. This arrangement can further reduce the area of ​​the non-display area NA occupied by the gate driving circuit 20, thereby increasing the screen-to-body ratio of the display panel 100.

[0041] In some embodiments, as shown in FIG3, the display panel 100 further includes a plurality of shared pixel circuit groups 12 arranged along a first direction X, each shared pixel circuit group 12 being electrically connected to a plurality of light-emitting units 10. Each shared pixel circuit group 12 includes a shared pixel circuit 121 and a plurality of auxiliary shared pixel circuits 122; the auxiliary shared pixel circuits 122 and the shared pixel circuit 121 are each electrically connected to a plurality of light-emitting devices 11 of the plurality of light-emitting units 10 that emit the same color.

[0042] This configuration allows the shared pixel circuit 121 and the auxiliary shared pixel circuit 122 to drive multiple light-emitting devices 11 with the same color, thereby ensuring the color display of multiple light-emitting units 10. Furthermore, since the auxiliary shared pixel circuit 122 connects multiple light-emitting devices 11 in the multiple light-emitting units 10, the light-emitting devices 11 in the light-emitting units 10 near the gate driving circuit 20 (e.g., the first light-emitting unit 101) do not require corresponding pixel circuits. This allows the area to be used for arranging at least some of the connecting lines 21 (or even further for arranging the gate driving circuit 20), thereby further improving the screen-to-body ratio of the display panel 100.

[0043] In some examples, each shared pixel circuit group 12 includes a shared pixel circuit 121 and two auxiliary shared pixel circuits 122, wherein the shared pixel circuit 121 is electrically connected to the red light-emitting device in the plurality of light-emitting units 10, one auxiliary shared pixel circuit 122 is electrically connected to the green light-emitting device in the plurality of light-emitting units 10, and the other auxiliary shared pixel circuit 122 is electrically connected to the blue light-emitting device in the plurality of light-emitting units 10.

[0044] In some embodiments, as shown in FIG3, the display panel 100 further includes a plurality of pixel circuits 13 located within the display area AA. Except for the light-emitting devices 11 electrically connected to the shared pixel circuit 121 (or auxiliary shared pixel circuit 122), the other light-emitting devices are electrically connected to a corresponding pixel circuit 13. This enables the driving of all light-emitting devices 11 within the display area AA, thereby displaying the desired image.

[0045] In some examples, the display panel 100 also includes multiple gate signal lines GL arranged side-by-side along a first direction X and multiple data signal lines DL arranged side-by-side along a second direction Y. Each gate signal line GL extends along the second direction Y, and each data signal line DL extends along the first direction X. Under the control of the scan signal transmitted by the gate signal line GL, the common pixel circuit 121, the auxiliary common pixel circuit 122, and the pixel circuit 13 transmit the data signal transmitted by the data signal line DL to the corresponding light-emitting device 11, thereby driving the light-emitting device 11 to emit light.

[0046] In some examples, the gate signal line GL is connected to the connection line 21. As an example, an insulating layer is provided between the layer where the connection line 21 is located and the layer where the gate signal line GL is located. A via is formed in the insulating layer, and one end of the connection line 21 is connected to a transition component. The transition component passes through the via and is connected to the gate signal line GL. Since the space corresponding to the selected light-emitting device 110 does not have a shared pixel circuit 121, this space can be used to arrange the transition component, thereby ensuring the connection between the gate signal line GL and the connection line 21.

[0047] In some embodiments, as shown in FIG3, a plurality of light-emitting units 10 electrically connected to the shared pixel circuit group 12 are arranged along the second direction Y. Since the plurality of light-emitting units 10 corresponding to the shared pixel circuit group 12 are arranged along the second direction Y, the space corresponding to one light-emitting unit 10 can be used to arrange the shared pixel circuit group 12, so that the space corresponding to the other light-emitting unit 10 can be used to arrange at least part of the connecting lines 21 (or even further arrange the gate driving circuit 20), thereby further narrowing the width of the non-display area NA, thereby increasing the screen ratio of the display panel 100.

[0048] In some examples, each light-emitting device 11 in the plurality of light-emitting units 10 is electrically connected to the corresponding common pixel circuit 121 or auxiliary common pixel circuit 122 in the common pixel circuit group 12, and the number of light-emitting devices 11 connected to each auxiliary common pixel circuit 122 is equal to the number of light-emitting devices 11 connected to the common pixel circuit 121.

[0049] In some examples, each shared pixel circuit group 12 may be electrically connected to two light-emitting units 10. In other examples, each shared pixel circuit group 12 may be electrically connected to more than two light-emitting units 10. For example, each shared pixel circuit group 12 may correspond to three, four, or six light-emitting units 10, etc., and the embodiments of this application do not impose any limitations on this.

[0050] In some embodiments, as shown in Figures 4 and 8, each light-emitting unit 10 includes two first light-emitting devices 111, two second light-emitting devices 112, and four third light-emitting devices 113, and the first light-emitting devices 111, the second light-emitting devices 112, and the third light-emitting devices 113 emit different colors.

[0051] Two first light-emitting devices 111 and two second light-emitting devices 112 are arranged in an array. For example, the geometric centers of the two first light-emitting devices 111 and the two second light-emitting devices 112 are located at the vertices of a quadrilateral.

[0052] Two first light-emitting devices 111 are arranged diagonally, and two second light-emitting devices 112 are also arranged diagonally. For example, one first light-emitting device 111 and one second light-emitting device 112 are arranged along a first direction X, and the first light-emitting device 111 and the other second light-emitting device 112 are arranged along a second direction Y; the two first light-emitting devices 111 are arranged along a third direction M, and the two second light-emitting devices 112 are arranged along a fourth direction N, wherein the third direction M and the fourth direction N can be perpendicular to each other. In addition, the angle between the fourth direction N and the first direction X can be 45°.

[0053] Four third light-emitting devices 113 are arranged in an array. For example, the geometric centers of the four third light-emitting devices 113 are located at the vertices of a quadrilateral.

[0054] A third light-emitting device 113 is located between two first light-emitting devices 111 and between two second light-emitting devices 112, and a first light-emitting device 111 is located between two diagonally arranged third light-emitting devices 113. Furthermore, the geometric centers of the two diagonally arranged third light-emitting devices and the two diagonally arranged first light-emitting devices 111 can be collinear. For example, the two diagonally arranged third light-emitting devices 113 and the two first light-emitting devices 111 are arranged along a third direction M, and in the third direction M, the distance between the geometric centers of the two third light-emitting devices 113 and the geometric center of the first light-emitting device 111 located between the two third light-emitting devices 113 is equidistant.

[0055] With this configuration, the third light-emitting device 113 located between the two first light-emitting devices 111 can be shared by any adjacent first light-emitting device 111 and second light-emitting device 112 in the light-emitting unit 10 at the same time, and other third light-emitting devices 113 can be shared by adjacent first light-emitting devices 111 and second light-emitting devices 112 in adjacent light-emitting units 10 at the same time. This can effectively improve the image clarity and detail of the display panel 100, thereby improving the imaging quality.

[0056] In some examples, the first light-emitting device 111, the second light-emitting device 112, and the third light-emitting device 113 can be a blue light-emitting device, a red light-emitting device, and a green light-emitting device, respectively.

[0057] In some embodiments, as shown in Figures 2 and 3, each shared pixel circuit group 12 is electrically connected to two light-emitting units 10 on the side closest to the gate driving circuit 20. This allows the two light-emitting units 10 to share a shared pixel circuit group 12 for driving, thereby saving space to arrange at least part of the connection line 21 (and even further arrange the gate driving circuit 20).

[0058] The two light-emitting units 10 include a first light-emitting unit 101 and a second light-emitting unit 102 arranged sequentially along the direction away from the gate driving circuit 20, and the shared pixel circuit group 12 is located in the area where the second light-emitting unit 102 is located.

[0059] This ensures that the shared pixel circuit group 12 is kept away from the selected light-emitting device 110, thereby expanding the space for laying the connection line 21 (or even the gate drive circuit 20), and thus increasing the screen ratio of the display panel 100.

[0060] In some examples, as shown in Figures 4, 5, 8, and 9, the shared pixel circuit group 12 includes a shared pixel circuit 121 and three auxiliary shared pixel circuits 122, wherein two of the auxiliary shared pixel circuits 122 are each electrically connected to four third light-emitting devices 113. Furthermore, four first light-emitting devices 111 are electrically connected to one of the shared pixel circuit 121 and the other auxiliary shared pixel circuit 122, and four second light-emitting devices 112 are electrically connected to the other of the shared pixel circuit 121 and the other auxiliary shared pixel circuit 122.

[0061] This configuration allows the shared pixel circuit 121 to drive four light-emitting devices 11 with the same color, and each auxiliary shared pixel circuit 122 to drive four light-emitting devices 11 with the same color. This is beneficial for the layout design of the shared pixel circuit 121, and also avoids excessive load caused by too many light-emitting devices 11 connected to one auxiliary shared pixel circuit 122.

[0062] In some embodiments, as shown in Figures 4 and 5, for a shared pixel circuit group 12, two auxiliary shared pixel circuits 122 are arranged along the second direction Y to form a first circuit set, and another auxiliary shared pixel circuit 122 and a shared pixel circuit 121 are arranged along the second direction Y to form a second circuit set. The first circuit set and the second circuit set are arranged along the first direction X.

[0063] This configuration allows the shared pixel circuit group 12 to make full use of the space along the first direction X in the area where the second light-emitting unit 102 is located, thereby expanding the space along the second direction Y in the area where the second light-emitting unit 102 is located to lay out the connecting line 21 (or even the gate driving circuit 20), thereby increasing the screen ratio of the display panel 100.

[0064] In some embodiments, as shown in Figures 4 and 5, four third light-emitting devices 113 in the two light-emitting units 10 are arranged in parallel along the second direction Y, and another four third light-emitting devices 113 are arranged in parallel along the second direction Y. The four third light-emitting devices 113 arranged along the second direction Y can form a first device set, and the other four third light-emitting devices 113 can form a second device set. The first device set and the second device set can be arranged along the first direction X.

[0065] This configuration allows for the activation of the third light-emitting device 113 in either the first or second device set, in conjunction with the first and second light-emitting devices 111 and 112, to achieve displays at different positions. This enables precise control over the position of the two light-emitting units 10, thereby improving the display effect of the display panel 100.

[0066] In some examples, the auxiliary shared pixel circuit 122 electrically connected to the third light-emitting device 113 in the first device set and the auxiliary shared pixel circuit 122 electrically connected to the third light-emitting device 113 in the second device set are located on the same side. This arrangement is advantageous for the layout design of the shared pixel circuit 121 and the auxiliary shared pixel circuit 122.

[0067] In some examples, the four third light-emitting devices 113 in the first device set are respectively the first third light-emitting device 1131, the second third light-emitting device 1132, the third third light-emitting device 1133, and the fourth third light-emitting device 1134 arranged sequentially along the second direction Y. Among them, the first third light-emitting device 1131 and the second third light-emitting device 1132 are located in the first light-emitting unit 101, and the third third light-emitting device 1133 and the fourth third light-emitting device 1134 are located in the second light-emitting unit 102.

[0068] The four third light-emitting devices 113 in the second device set are the fifth third light-emitting device 1135, the sixth third light-emitting device 1136, the seventh third light-emitting device 1137, and the eighth third light-emitting device 1138, which are arranged sequentially along the second direction Y. Among them, the fifth third light-emitting device 1135 and the sixth third light-emitting device 1136 are located in the first light-emitting unit 101, and the seventh third light-emitting device 1137 and the eighth third light-emitting device 1138 are located in the second light-emitting unit 102.

[0069] In some examples, the shared pixel circuit group 12 may be located below the third third light-emitting device 1133, the fourth third light-emitting device 1134, the seventh third light-emitting device 1137, and the eighth third light-emitting device 1138. This allows the shared pixel circuit group 12 to be located further away from the gate drive circuit 20, thereby leaving more space for the wiring 21 and narrowing the bezel of the display panel 100.

[0070] In some embodiments, as shown in Figures 4 to 7 and Figure 13, the display panel 100 includes a first transition layer 1019 and a first electrode layer 1021 disposed on a substrate 1001 and stacked thereon, and each light-emitting device 11 includes a first electrode 1101 located in the first electrode layer 1021.

[0071] The four first light-emitting devices 111 electrically connected to the same shared pixel circuit 121 or the same auxiliary shared pixel circuit 122 include a first first light-emitting device 1111 and a third first light-emitting device 1113 located within the first light-emitting unit 101, and a second first light-emitting device 1112 and a fourth first light-emitting device 1114 located within the second light-emitting unit 102. Correspondingly, the four second light-emitting devices 112 electrically connected to the same shared pixel circuit 121 or the same auxiliary shared pixel circuit 122 include a first second light-emitting device 1121 and a third second light-emitting device 1123 located within the first light-emitting unit 101, and a second second light-emitting device 1122 and a fourth second light-emitting device 1124 located within the second light-emitting unit 102. The first first light-emitting device 1111, the first second light-emitting device 1121, the second first light-emitting device 1112, and the second second light-emitting device 1122 are arranged along the second direction Y.

[0072] The first electrodes 1101 of the four first light-emitting devices 111 are connected by a first adapter. For example, the first adapter includes a first connecting segment 31 connecting the fourth first light-emitting device 1114 and the second first light-emitting device 1112, a second connecting segment 32 connecting the second first light-emitting device 1112 and the first first light-emitting device 1111, and a third connecting segment 33 connecting the first first light-emitting device 1111 and the third first light-emitting device 1113.

[0073] It is worth noting that the aforementioned connecting segments are respectively connected to the first electrodes 1101 of the two corresponding light-emitting devices. Specifically, the first connecting segment 31 passes through the wiring space between the fourth second light-emitting device 1124 and the third third light-emitting device 1133; the second connecting segment 32 passes through the wiring space between the first second light-emitting device 1121 and the second third light-emitting device 1132, as well as the wiring space between the first second light-emitting device 1121 and the first third light-emitting device 1131; and the third connecting segment 33 passes through the wiring space between the third second light-emitting device 1123 and the first third light-emitting device 1131.

[0074] The first electrodes 1101 of the four second light-emitting devices 112 are connected via a second adapter. For example, the second adapter includes a fourth connecting segment 41 connecting the second second light-emitting device 1122 and the first second light-emitting device 1121, a fifth connecting segment 42 connecting the first second light-emitting device 1121 and the third second light-emitting device 1123, and a sixth connecting segment connecting the third second light-emitting device 1123 and the fourth second light-emitting device 1124. It is worth noting that the aforementioned connecting segments are respectively connected to the first electrodes 1101 of the corresponding two light-emitting devices. Specifically, the fourth connecting segment 41 passes through the wiring space of the second first light-emitting device 1112 away from the fourth second light-emitting device 1124; the fifth connecting segment 42 passes through the wiring space of the first first light-emitting device 1111 away from the first third light-emitting device 1131; and the sixth connecting segment 43 passes through the wiring space between the third first light-emitting device 1113 and the fifth third light-emitting device 1135, as well as the wiring space between the third first light-emitting device 1113 and the sixth third light-emitting device 1136.

[0075] For the four third light-emitting devices 113 arranged along the second direction Y, the first electrodes 1101 of the first two third light-emitting devices 113 are connected by a third adapter 51, the first electrodes 1101 of the last two third light-emitting devices 113 are connected by a fourth adapter 53, and the first electrodes 1101 of the two middle third light-emitting devices 113 are connected by a transition connector 52. For example, the first third light-emitting device 1131 and the second third light-emitting device 1132 are connected by the third adapter 51, and the third adapter 51 passes through the wiring space between the first second light-emitting device 1121 and the third first light-emitting device 1113; the third third light-emitting device 1133 and the fourth third light-emitting device 1134 are connected by the fourth adapter 53, and the fourth adapter 53 passes through the wiring space between the second second light-emitting device 1122 and the fourth first light-emitting device 1114; the second third light-emitting device 1132 and the third third third light-emitting device 1133 are connected by the transition connector 52.

[0076] The first electrodes 1101 of the other four third light-emitting devices 113 arranged along the second direction Y are connected via a fifth adapter. For example, the fifth adapter includes a seventh connecting segment 61 connecting the fifth third light-emitting device 1135 and the sixth third light-emitting device 1136, an eighth connecting segment 62 connecting the sixth third light-emitting device 1136 and the seventh third light-emitting device 1137, and a ninth connecting segment 63 connecting the seventh third light-emitting device 1137 and the eighth third light-emitting device 1138. The seventh connecting segment 61 passes through the wiring space of the sixth connecting segment 63 on the side away from the third first light-emitting device 1113, the eighth connecting segment 62 passes through the wiring space of the fourth second light-emitting device 1124 on the side away from the second first light-emitting device 1112, and the ninth connecting segment 63 passes through the wiring space of the fourth first light-emitting device 1114 on the side away from the second second light-emitting device 1122.

[0077] The first, second, third, fourth, and fifth adapters are all located in the first electrode layer 1021, meaning that the first, second, third, fourth, and fifth adapters, as well as the first electrode 1101 of each light-emitting device 11, can be fabricated simultaneously. The transition connector 52 is located in the first adapter layer 1019. An insulating layer (e.g., a ninth insulating layer 1020) is provided between the first adapter layer 1019 and the first electrode layer 1021. The transition connector 52 can be connected to the second and third light-emitting devices 1132 and 1133 through vias located in this insulating layer.

[0078] By placing the transition connector 52 in the first transition layer 1019, the transition connector 52 and the first connection segment 31 can cross each other but not form an electrical connection, thereby ensuring that the shared pixel circuit 121 and each auxiliary shared pixel circuit 122 can stably drive the corresponding multiple light-emitting devices 11.

[0079] In some embodiments, as shown in Figures 4 to 7, the first transition layer 1019 is further provided with a plurality of connection portions. Each connection portion can serve as a connection terminal of a common pixel circuit 121 or an auxiliary common pixel circuit 122 to be electrically connected to a corresponding light-emitting device 11. For example, the plurality of connection portions include a first connection portion 71, a second connection portion 72, a third connection portion 73, and a fourth connection portion 74. The first connection portion 71 can serve as a connection terminal of the common pixel circuit 121 to be electrically connected to the second first light-emitting device 1112 through a via located in the ninth insulating layer; the second connection portion 72 can serve as a connection terminal of an auxiliary common pixel circuit 122 to be electrically connected to the fourth third light-emitting device 1134 through a via located in the ninth insulating layer; the third connection portion 73 can serve as a connection terminal of an auxiliary common pixel circuit 122 to be electrically connected to the eighth third light-emitting device 1138 through a via located in the ninth insulating layer; and the fourth connection portion 74 can serve as a connection terminal of an auxiliary common pixel circuit 122 to be electrically connected to the fourth second light-emitting device 1124 through a via located in the ninth insulating layer.

[0080] In some examples, each light-emitting device 11 also includes a light-emitting layer and a second electrode arranged sequentially on the side of the first electrode 1101 away from the substrate 1001, and the second electrodes of multiple light-emitting devices 11 can be connected to each other. In this case, since the first electrodes of multiple light-emitting devices 11 with the same emission color are connected sequentially, multiple light-emitting devices 11 with the same emission color can be connected in parallel.

[0081] In some embodiments, as shown in Figures 8 to 12, the common pixel circuit 121 and three auxiliary common pixel circuits 122 are arranged along the second direction Y.

[0082] This configuration allows the shared pixel circuit group 12 to effectively utilize the space along the second direction Y in the area where the second light-emitting unit 102 is located, thereby ensuring that the shared pixel circuit group 12 has a good spatial arrangement.

[0083] In some embodiments, as shown in FIG8 and FIG9, the two light-emitting units 10 include a first light-emitting unit 101 and a second light-emitting unit 102 arranged sequentially along the direction away from the gate driving circuit 20; the four third light-emitting devices 113 in the first light-emitting unit 101 are connected in parallel with each other, and the four third light-emitting devices 113 in the second light-emitting unit 102 are connected in parallel with each other.

[0084] Since the four shared pixel circuits 121 are arranged along the second direction Y, the connection between the third light-emitting device 113 located in each light-emitting unit 10 and the corresponding shared pixel circuit 121 is facilitated by connecting the third light-emitting device 113 in parallel with each other.

[0085] In some embodiments, as shown in Figures 8 to 13, the display panel 100 includes a second transition layer 1017, a first transition layer 1019, and a first electrode layer 1021 that are stacked sequentially on a substrate 1001, and each light-emitting device 11 includes a first electrode 1101 located in the first electrode layer 1021.

The eighth adapter 36 includes a first adapter segment 361 and a second adapter segment 362 connected in sequence. The second adapter segment 362 spans the data signal line connected to the shared pixel circuit group 12. The connection point between the first adapter segment 361 and the second adapter segment 362 is located on the side of the data signal line closer to the third light-emitting device 1113.

The ninth adapter 44 passes through the wiring space between the first first light-emitting device 1111 and the first third light-emitting device 1131.

[0089] The first electrodes of the four third light-emitting devices 113 in the first light-emitting unit 10 are connected through the twelfth adapter, and the first electrodes of the four third light-emitting devices 113 in the second light-emitting unit 10 are connected through the thirteenth adapter.

[0090] For example, the twelfth adapter includes a third adapter segment 54 connecting the first third light-emitting device 1131 and the fifth third light-emitting device 1135, a fourth adapter segment 55 connecting the fifth third light-emitting device 1135 and the sixth third light-emitting device 1136, and a sixth adapter segment 56 connecting the sixth third light-emitting device 1136 and the second third light-emitting device 1132. The third adapter segment 54 passes through the wiring space between the third second light-emitting device 1123 and the third first light-emitting device 1113, the fourth adapter segment 55 passes through the wiring space on the side of the third first light-emitting device 1113 away from the first second light-emitting device 1121, and the sixth adapter segment 56 passes through the wiring space between the third first light-emitting device 1113 and the fourth second light-emitting device 1124.

[0091] The thirteenth adapter includes a seventh adapter segment 64 connecting the third third light-emitting device 1133 and the seventh third light-emitting device 1137, an eighth adapter segment 65 connecting the seventh third light-emitting device 1137 and the eighth third light-emitting device 1138, and a ninth adapter segment 66 connecting the eighth third light-emitting device 1138 and the fourth third light-emitting device 1134. The seventh adapter segment 64 passes through the wiring space between the fourth second light-emitting device 1124 and the fourth first light-emitting device 1114, the eighth adapter segment 65 passes through the wiring space of the fourth first light-emitting device 1114 on the side away from the second second light-emitting device 1122, and the ninth adapter segment 66 passes through the wiring space of the fourth first light-emitting device 1114 on the side away from the fourth second light-emitting device 1124.

[0092] The second adapter segment 362 and the eleventh adapter 46 are located in the second adapter layer 1017; the seventh adapter 35, the eighth adapter 36, the first adapter segment 361, and the tenth adapter 45 are located in the first adapter layer 1019; and the ninth adapter 44, the twelfth adapter, and the thirteenth adapter are located in the first electrode layer 1021. An insulating layer (e.g., the ninth insulating layer 1020) is provided between the first adapter layer 1019 and the first electrode layer 1021, and another insulating layer (e.g., the eighth insulating layer 1018) is provided between the second adapter layer 1017 and the first adapter layer 1019. Devices (e.g., adapters) in any two adjacent conductive layers (the second adapter layer 1017, the first adapter layer 1019, and the first electrode layer 1021) are connected through vias in the insulating layer between the two conductive layers.

[0093] This configuration, by placing different adapters in different layers, ensures that the different adapters cross each other but do not form an electrical connection, thereby ensuring the stable driving of the shared pixel circuit 121 and each auxiliary shared pixel circuit 122 to their respective multiple light-emitting devices 11.

[0094] In some examples, as shown in FIG13, the display panel 100 further includes a light-shielding layer 1002, a barrier layer 1003, and a buffer layer 1004 sequentially located on the substrate 1001.

In this case, the first type of transistor and the second type of transistor can share the first source-drain layer 1015 to arrange their respective source and drain. The source of the second type of transistor can be connected to the drain of the first type of transistor through a via, thereby realizing the connection of different types of transistors to form a shared pixel circuit 121 (or an auxiliary shared pixel circuit 122) to drive the corresponding light-emitting device 11.
