Description

Technical Field

[0001] At least one embodiment of the present disclosure relates to a display panel and a display device. Background Art

[0002] As consumers continue to pursue the viewing angle of display products, extremely narrow bezels and even full-screen displays have become a new trend in the development of organic light-emitting diode (OLED) products. As the screen-to-body ratio of many high-end mobile phones has gradually and steadily increased, full-screen has become the current trend. The most critical issue of full-screen is how to deal with the front camera. In order to achieve a higher screen-to-body ratio, bangs screens, water drop screens, and punch-hole screens have appeared one after another. Although these full-screen forms have increased the screen-to-body ratio, the appearance of the mobile phone has decreased a lot. Therefore, considering all factors, the under-screen camera is the best form of full-screen.

[0003] The under-screen camera means that the front camera is located below the screen but does not affect the screen display function. When the front camera is not in use, the screen above the camera can still display the image normally. So from the appearance, the under-screen camera will not have any camera hole, and truly achieve a full-screen display effect. Summary of the invention

[0004] At least one embodiment of the present disclosure relates to a display panel and a display device.

[0005] At least one embodiment of the present disclosure provides a display panel, comprising: a substrate having a first display area and a second display area, wherein the first display area is located on at least one side of the second display area; a plurality of first pixel circuits located in the first display area; a plurality of first light-emitting elements located in the first display area, wherein the first pixel circuit is configured to drive at least one first light-emitting element among the plurality of first light-emitting elements; a plurality of second pixel circuits located in the first display area; a plurality of second light-emitting elements located in the second display area, wherein the second pixel circuit is configured to drive at least one second light-emitting element among the plurality of second light-emitting elements; and a plurality of conductive lines, wherein the second pixel circuit is connected to the second light-emitting element through at least one conductive line, wherein the plurality of second light-emitting elements include a plurality of groups, wherein at least one group among the plurality of groups includes a plurality of subgroups, wherein each subgroup includes at least one second light-emitting element, and in the same group, the conductive lines connected to the second light-emitting elements of different subgroups are located between the second light-emitting elements of different adjacent groups.

[0006] For example, the plurality of groups are arranged along a first direction, and the plurality of sub-groups are arranged along a second direction.

[0007] For example, the first direction includes a row direction, and the second direction includes a column direction.

[0008] For example, the conductive lines connected to the second light emitting elements in the same subgroup are located in the same layer.

[0009] For example, in the same group, conductive lines connected to second light-emitting elements in different subgroups are located in the same layer.

[0010] For example, the conductive lines include at least two overlapping conductive lines, and overlapping portions of two of the at least two overlapping conductive lines extend along the first direction.

[0011] For example, at least two insulating layers are arranged between the two overlapping conductive lines.

[0012] For example, in the same group, conductive lines connected to second light emitting elements of the same subgroup are located between second light emitting elements of the same adjacent group.

[0013] For example, the plurality of subgroups include a first subgroup and a second subgroup, and the conductive lines connected to the second light-emitting elements in the first subgroup and the conductive lines connected to the second light-emitting elements in the second subgroup are separated by at least one group of second light-emitting elements.

[0014] For example, the multiple subgroups also include a third subgroup, the first subgroup, the second subgroup and the third subgroup are arranged in sequence, and the conductive wire connected to the second light-emitting element in the second subgroup and the conductive wire connected to the second light-emitting element in the third subgroup are separated by at least one group of second light-emitting elements.

[0015] For example, the plurality of second pixel circuits are distributed between the plurality of first pixel circuits at intervals.

[0016] For example, at least one first pixel circuit among the multiple first pixel circuits is connected to at least one first light-emitting element among the multiple first light-emitting elements, and the orthographic projection of the at least one first pixel circuit on the substrate at least partially overlaps with the orthographic projection of the at least one first light-emitting element on the substrate.

[0017] For example, at least one second pixel circuit among the plurality of second pixel circuits is connected to at least one second light emitting element among the plurality of second light emitting elements through at least one conductive line.

[0018] For example, the orthographic projections of the plurality of second pixel circuits on the base substrate do not overlap with the orthographic projections of the plurality of second light emitting elements on the base substrate.

[0019] For example, the first display area surrounds the second display area, and the shape of the second display area includes a circle.

[0020] For example, the second display area is axisymmetric.

[0021] For example, the second display area includes a first symmetry axis extending along the first direction and a second symmetry axis extending along the second direction.

[0022] For example, the plurality of conductive lines include a plurality of first conductive lines located in a first pattern layer, a plurality of second conductive lines located in a second pattern layer, and a plurality of third conductive lines located in a third pattern layer. The first pattern layer, the second pattern layer, and the third pattern layer are arranged in sequence, and an orthographic projection of a first conductive line located in the first pattern layer on the base substrate partially overlaps with an orthographic projection of a third conductive line located in the third pattern layer on the base substrate.

[0023] For example, the conductive line includes a portion of a virtual dividing line passing through the first display area and the second display area, and the portion of the conductive line connected to different subgroups of second light-emitting elements that passes through the virtual dividing line between the first display area and the second display area is located between different adjacent groups of second light-emitting elements.

[0024] At least one embodiment of the present disclosure further provides a display device, comprising any one of the above-mentioned display panels.

[0025] For example, the display device further includes a photosensor, and the photosensor is located on one side of the display panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0055] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, "include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0056] Figure 1 is a schematic diagram of a display panel provided by an embodiment of the present disclosure. Figure 1As shown, the display panel may include: a substrate BS. The display panel includes a first display area R1 and a second display area R2, and the first display area R1 may be located on at least one side of the second display area R2. For example, in some embodiments, the first display area R1 surrounds the second display area R2. That is, the second display area R2 may be surrounded by the first display area R1. The second display area R2 may also be set at other positions, and the setting position of the second display area R2 may be determined as required. For example, the second display area R2 may be located at the top center of the substrate BS, or at the upper left corner or upper right corner of the substrate BS. For example, hardware such as a photosensitive sensor (such as a camera) is set in the second display area R2 of the display panel. For example, the second display area R2 is a light-transmitting display area, and the first display area R1 is a display area. For example, the first display area R1 is opaque and is only used for display. Figure 1 The peripheral area R3 is also shown. For example, the peripheral area R3 is a non-display area.

[0057] In a typical display panel, the density of the light-emitting elements in the second display area R2 is lower than that in the first display area R1, and the display brightness of the second display area R2 is much lower than that of the first display area R1. For example, the brightness of the first display area R1 is twice that of the second display area R2, resulting in uneven display brightness.

[0058] Figure 2 FIG. 1 is a schematic diagram of a pixel unit of a display panel provided by an embodiment of the present disclosure. The display panel includes a pixel unit 100, and the pixel unit 100 is located on a substrate. Figure 2 As shown, the pixel unit 100 includes a pixel circuit 100a and a light-emitting element 100b, and the pixel circuit 100a is configured to drive the light-emitting element 100b. For example, the pixel circuit 100a is configured to provide a driving current to drive the light-emitting element 100b to emit light. For example, the light-emitting element 100b is an organic light-emitting diode (OLED), and the light-emitting element 100b emits red light, green light, blue light, or white light when driven by its corresponding pixel circuit 100a. The color of the light emitted by the light-emitting element 100b can be determined according to needs. Figure 2 As shown, the light emitting element 100b includes a first electrode E1 and a second electrode E2 and a light emitting functional layer located between the first electrode E1 and the second electrode E2. For example, the first electrode E1 is an anode and the second electrode E2 is a cathode, but not limited thereto. For example, the first electrode E1 may be a pixel electrode and the second electrode E2 may be a common electrode.

[0059] In order to improve the light transmittance of the second display area R2, only the light emitting element may be arranged in the second display area R2, and the pixel circuit driving the light emitting element of the second display area R2 may be arranged outside the second display area R2, for example, the pixel circuit driving the light emitting element of the second display area R2 may be arranged in the first display area R1 or the peripheral area R3. That is, the light transmittance of the second display area R2 is improved by separately arranging the light emitting element and the pixel circuit.

[0060] Figure 3 is a schematic diagram of a display panel provided by an embodiment of the present disclosure. Figure 3 As shown, the display panel includes: a plurality of first pixel circuits 10, a plurality of second pixel circuits 20 and a plurality of first light-emitting elements 30 located in the first display area R1, and a plurality of second light-emitting elements 40 located in the second display area R2. For example, the plurality of second pixel circuits 20 may be distributed between the plurality of first pixel circuits 10 at intervals.

[0061] For example, Figure 3 As shown, at least one first pixel circuit 10 among the plurality of first pixel circuits 10 may be connected to at least one first light-emitting element 30 among the plurality of first light-emitting elements 30, and the orthographic projection of at least one first pixel circuit 10 on the substrate BS may at least partially overlap with the orthographic projection of at least one first light-emitting element 30 on the substrate BS. The at least one first pixel circuit 10 may be used to provide a driving signal to the connected first light-emitting element 30 to drive the first light-emitting element 30 to emit light.

[0062] For example, Figure 3 As shown, at least one second pixel circuit 20 among the plurality of second pixel circuits 20 can be connected to at least one second light-emitting element 40 among the plurality of second light-emitting elements 40 through a conductive line L1, and the at least one second pixel circuit 20 can be used to provide a driving signal to the connected second light-emitting element 40 to drive the second light-emitting element 40 to emit light. Figure 3 As shown, since the second light emitting element 40 and the second pixel circuit 20 are located in different areas, the orthographic projection of at least one second pixel circuit 20 on the substrate BS does not overlap with the orthographic projection of at least one second light emitting element 40 on the substrate BS.

[0063] For example, in the embodiment of the present disclosure, the first display area R1 can be set as a non-light-transmitting display area, and the second display area R2 can be set as a light-transmitting display area. For example, the first display area R1 is not light-transmitting, and the second display area R2 is light-transmitting. In this way, the display panel provided by the embodiment of the present disclosure does not need to be processed by digging holes on the display panel, and the required hardware structures such as the photosensitive sensor can be directly set at the position corresponding to the second display area R2 on one side of the display panel, laying a solid foundation for the realization of a true full screen. In addition, since the second display area R2 only includes light-emitting elements but not pixel circuits, it is beneficial to improve the transmittance of the second display area R2, so that the display panel has a better display effect.

[0064] like Figure 3 As shown, the pixel unit 100 includes a first pixel unit 101 and a second pixel unit 102. The pixel circuit 100a and the light-emitting element 100b of the first pixel unit 101 are both located in the first display area R1, the pixel circuit 100a of the second pixel unit 102 is located in the first display area R1, and the light-emitting element 100b of the second pixel unit 102 is located in the second display area R2. In the embodiment of the present disclosure, the pixel circuit 100a of the first pixel unit 101 is the first pixel circuit 10, the light-emitting element 100b of the first pixel unit 101 is the first light-emitting element 30, the pixel circuit 100a of the second pixel unit 101 is the second pixel circuit 20, and the light-emitting element 100b of the second pixel unit 102 is the second light-emitting element 40. For example, the first pixel circuit 10 can be referred to as an in-situ pixel circuit, and the second pixel circuit 20 can be referred to as a non-in-situ pixel circuit.

[0065] For example, Figure 3 As shown, the second light emitting element 40 and the second pixel circuit 20 connected to the second light emitting element 40 are located in the same row. That is, the light emitting signal of the second light emitting element 40 comes from the second pixel circuit in the same row. For example, the pixel circuits of the pixel units in the same row are connected to the same gate line.

[0066] like Figure 3 As shown, the pixel circuit (second pixel circuit 20) of the second pixel unit 102 is connected to the light-emitting element (second light-emitting element 40) of the second pixel unit 102 through the conductive line L1. For example, the conductive line L1 is made of a transparent conductive material. For example, the conductive line L1 is made of a conductive oxide material. For example, the conductive oxide material includes indium tin oxide (ITO), but is not limited thereto.

[0067] like Figure 3 As shown, one end of the conductive line L1 is connected to the second pixel circuit 20, and the other end of the conductive line L1 is connected to the second light emitting element 40. Figure 3As shown, the conductive line L1 extends from the first display area R1 to the second display area R2. In other words, the conductive line L1 extends from the second display area R2 to the first display area R1.

[0068] In order to improve the display effect, the density of the second light-emitting element 40 can be equal to the density of the first light-emitting element 30. That is, the resolution of the second display area R2 is the same as that of the first display area R1, the brightness of the second display area R2 is improved, the problem of low brightness of the second display area is solved, the uniformity of the picture of the second display area R2 is improved, and the brightness difference between the second display area R2 and the first display area R1 is reduced, so as to achieve a more uniform full-screen visual display effect. Moreover, since the brightness difference between the second display area R2 and the first display area R1 is reduced, it is conducive to obtaining a larger second display area R2, and achieving a better full-screen display effect and user experience.

[0069] For example, in some embodiments, the brightness of the second display area R2 is the same as the brightness of the first display area R1. Of course, in other embodiments, the density of the second light-emitting element 40 may be greater or less than the density of the first light-emitting element 30. That is, the resolution of the second display area R2 may be greater or less than the resolution of the first display area R1. For example, in some embodiments, the light-emitting area of ​​the second light-emitting element 40 is smaller than the light-emitting area of ​​the first light-emitting element 30.

[0070] Figure 4 A schematic diagram of a first display area and a second display area in a display panel provided in an embodiment of the present disclosure. Figure 4 The dotted lines show the light emitting region of the second light emitting element 40 and the light emitting region of the first light emitting element 30. For example, the light emitting region of the light emitting element may correspond to the opening of the pixel definition layer.

[0071] Figure 5 Schematic diagram of a display panel provided by an embodiment of the present disclosure. Figure 5 As shown, the transistor T0 is located on the substrate BS, the transfer electrode CE0 is connected to the transistor T0 through the via hole H2 penetrating the insulating layer 401, the first electrode E1 of the light-emitting element 100b is connected to the transfer electrode CE0 through the via hole H1 penetrating the insulating layer 402, and a pixel definition layer PDL is provided above the first electrode E1. The pixel definition layer PDL has an opening OPN, and the opening OPN defines the light-emitting area R0 of the light-emitting element 100b. Figure 5 The light-emitting functional layer FL and the second electrode E2 are also shown. For example, the first electrodes E1 of different pixel units are independent of each other and spaced apart from each other. For example, the second electrodes E2 of different pixel units can be formed in one piece. Figure 5 As shown, the switching electrode CE0 includes a first switching electrode CE1 and a second switching electrode CE2. Figure 5As shown, the first switching electrode CE1 is connected to the first pixel circuit 10 , and the second switching electrode CE2 is connected to the second pixel circuit 20 .

Figure 7 A schematic diagram of a first electrode of a light-emitting element in a display panel provided in an embodiment of the present disclosure. Figure 8 A schematic diagram of a second display area in a display panel and a first electrode located in the second display area provided in an embodiment of the present disclosure.

[0073] like Figure 6 and Figure 7 As shown, the first electrode E1 includes a first electrode E11 and a first electrode E12, the first electrode E11 is located in the first display region R1, and the first electrode E12 is located in the second display region R2. Figure 6 The second display area R2 in is a rectangle, Figure 7 The shape of the second display area R2 in the embodiment is circular. The embodiment of the present disclosure does not limit the shape of the second display area R2. For example, the shape of the second display area R2 can also be elliptical. The shape of the second display area R2 can be determined as needed. In some embodiments of the present disclosure, the circular second display area R2 is used as an example for description.

[0074] For example, for a square second display area R2 and a circular second display area R2, the circular areas have the same diameter and the same PPI. The number of first electrodes E1 in the circular second display area R2 is about 21.46% less than that in the square second display area R2, and the number of conductive lines L1 required to be set is relatively small. Therefore, in the case of high PPI, the circular second display area R2 can be selected.

[0075] For example, Figure 8 As shown, the first display area R1 surrounds the second display area R2, and the second display area R2 is circular in shape. Figure 8 As shown, the second display area R2 is axisymmetric. Figure 8 As shown, the second display region R2 includes a first symmetric axis A1 extending along the first direction X and a second symmetric axis A2 extending along the second direction Y.

[0076] Figure 8 The second display area R2 includes a first sub-area R21, a second sub-area R22, a third sub-area R23, and a fourth sub-area R24. Figure 8 As shown, the first sub-region R21 and the second sub-region R22 are symmetrically arranged with respect to the second symmetry axis A2, and the third sub-region R23 and the fourth sub-region R24 are symmetrically arranged with respect to the second symmetry axis A2.

[0077] like Figure 8 As shown, the first sub-region R21 and the third sub-region R23 are symmetrically arranged with respect to the first symmetry axis A1, and the second sub-region R22 and the fourth sub-region R24 are symmetrically arranged with respect to the first symmetry axis A1.

[0078] The embodiment of the present disclosure is described by taking the first direction X as the row direction and the second direction Y as the column direction as an example. Of course, in other embodiments, the first direction X may be the column direction and the second direction Y may be the row direction.

[0079] refer to Figure 3 The display panel includes: a base substrate BS, a plurality of first pixel circuits 10, a plurality of first light emitting elements 30, a plurality of second pixel circuits 20, a plurality of second light emitting elements 40, and a plurality of conductive lines L1.

For example, Fig. 9 and Fig.10 As shown, a plurality of groups G are arranged along a first direction X. For example, Fig. 9 and Fig.10 As shown, each group extends along the second direction Y.

[0087] like Fig. 9 and Fig.10 As shown, the first group G1 includes two subgroups S, and the two subgroups S include a first subgroup S1 and a second subgroup S2. Fig. 9 As shown, in the first group G1, the first subgroup S1 includes four light emitting elements 40, and the second subgroup S2 includes four light emitting elements 40. Fig.10 As shown, in the first group G1, the first subgroup S1 includes two light emitting elements, and the second subgroup S2 includes two light emitting elements. Fig. 9 and Fig.10 As shown, in the first group G1, a plurality of subgroups S are arranged along the second direction Y. Fig. 9 and Fig.10 As shown, the light emitting elements in each subgroup S are arranged along the second direction Y.

[0088] like Fig. 9 and Fig.10 As shown, one light emitting element 40 is connected to one conductive line L1. Fig. 9 The conductive lines L1 shown are all located in the same layer. Fig. 9The conductive line L1 shown may be referred to as a first conductive line L11 . Fig.10 The conductive lines L1 shown are all located in the same layer. Fig.10 The conductive line L1 shown may be referred to as a first conductive line L11. The first conductive line L11 is located in the first pattern layer LY1.

For example, the case where the conductive lines L1 connected to the second light-emitting elements 40 of each subgroup S in the same group G are all located between the second light-emitting elements 40 of the same adjacent group includes that the conductive line L1 connected to the second light-emitting element 40 of the first subgroup S1 in the first group G1 is located between the first group G1 and the second group G2, and the conductive line L1 connected to the second light-emitting element 40 of the second subgroup S2 in the first group G1 is also located between the first group G1 and the second group G2.

[0093] The arrangement of the conductive wires of other odd groups may refer to the arrangement of the conductive wires of the first group, and will not be described in detail here.

[0094] like Figures 9 to 12 As shown, in the same group G, the conductive line L1 connected to the second light emitting elements 40 of the same subgroup S is located between the second light emitting elements 40 of the same adjacent group. Fig. 9 and Fig.12 As shown, for the first group G1, the conductive lines L1 connected to the second light emitting elements 40 of the first subgroup S1 are all located between the second light emitting elements 40 of the first group G1 and the second light emitting elements 40 of the second group G1.

The arrangement of the conductive lines connected to the second light emitting elements of other groups can refer to the arrangement of the conductive lines connected to the second light emitting elements of the first group G1.

Fig.18A A schematic cross-sectional view of a display panel provided according to an embodiment of the present disclosure. Fig.18B A schematic cross-sectional view of a display panel provided according to an embodiment of the present disclosure.

[0097] For example, in the embodiment of the present disclosure, a group of light emitting elements can also be regarded as a group of first electrodes E1. The conductive line L1 connected to the light emitting element is the conductive line L1 connected to the first electrode E1 of the light emitting element.

[0098] refer to Figures 12 to 15 The first electrodes E1 of the first group G1 from right to left are connected one by one using the first conductive line L11.

[0099] The gaps between the first electrodes E1 of the first group G1 and the first electrodes E1 of the second group G2 are filled with the first conductive lines L11 connected to the first electrodes E1 of the first subgroup S1 of the first group G; the first conductive lines L11 connected to the first electrodes E1 of the second subgroup S2 of the first group G skip the first electrodes E1 of the second group G2, and are arranged in the gaps between the first electrodes E1 of the second group G2 and the first electrodes E1 of the third group G3, so that the first conductive lines L11 connected to the first electrodes E1 of the odd-numbered groups are periodically designed. The second conductive lines L12 are designed in the same way as the first conductive lines L11, except that they are connected to the first electrodes E1 of the even-numbered groups. The design of the conductive lines L1 in the entire second display area can be obtained by designing in the same way or by left-right and top-bottom mirroring.

[0100] The same group of light-emitting elements can be regarded as the same column of light-emitting elements, and the same group of first electrodes can be regarded as the same column of first electrodes. For example, in the same group, the conductive lines connected to the second light-emitting elements of different subgroups are located between the second light-emitting elements of different adjacent groups, including in the same column, the conductive lines connected to the second light-emitting elements of different subgroups are located between the second light-emitting elements of different adjacent columns.

[0101] For example, when the conductive line is formed by two pattern layers, namely, the first conductive line L11 and the second conductive line L12, in order to reduce the loading between the conductive lines, the first conductive line L11 and the second conductive line L12 are alternately routed in each other's gaps to minimize the overlap between the two layers.

[0102] For clarity of illustration, Fig.12 The following example is used to illustrate that the portions of different conductive lines L1 extending in the second direction Y do not overlap and the conductive lines located in the same layer are close to each other. In other embodiments, the above example can be adjusted appropriately. Fig.17 As shown, in order to facilitate manufacturing, in the conductive lines L1 between two adjacent groups, the conductive lines located in different layers are alternately arranged in the first direction X.

[0103] Fig.18A A first conductive line L11 is shown. Fig.18B The second conductive line L12 is shown. The first conductive line L11 is located in the first pattern layer LY1, and the second conductive line L12 is located in the second pattern layer LY2.

Fig. 22 for Fig.19 Schematic diagram of a third conductive line, a second pixel circuit and a second light-emitting element respectively connected to the third conductive line. Fig.23 The diagram is a schematic diagram of at least two insulating layers being provided between two overlapping conductive lines.

[0108] like Fig.19 As shown, different conductive lines L1 may cross or overlap, but because there is an insulating layer between the different conductive lines at the overlapping and crossing positions, the different conductive lines L1 are insulated from each other and the different conductive lines L1 are not electrically connected.

[0109] refer to Fig.19 and Fig. 20 , the first conductive line L11 is located in the first pattern layer LY1. Fig.19 and Fig.21 , the second conductive line L12 is located in the second pattern layer LY2. Fig.19 and Fig. 22 , the third conductive line L13 is located in the third pattern layer LY3. In the embodiment of the present disclosure, a conductive line is formed by the material of the same pattern layer as an example. It should be noted that in other embodiments, the same conductive line can also be formed by materials of different pattern layers, and the parts located in different pattern layers are connected by vias penetrating the insulating layer.

[0110] refer to Fig.19 , the second light emitting elements 40 in the same column are respectively connected to the second pixel circuits 20 in the same column. Fig.19 The second light emitting elements 40 in the same row are respectively connected to the second pixel circuits 20 in the same row. Fig.19 Taking the second pixel circuit 20 being located in the first display area R1 as an example, in other embodiments, the second pixel circuit 20 may be located in the peripheral area.

[0111] refer to Fig. 9 , Fig.12 ,as well as Fig.19 The plurality of subgroups S include a first subgroup S1 and a second subgroup S2, and the conductive lines L1 connected to the second light-emitting elements 40 in the first subgroup S1 and the conductive lines L1 connected to the second light-emitting elements 40 in the second subgroup S2 are separated by at least one group of second light-emitting elements 40. For example, the conductive lines L1 connected to the second light-emitting elements 40 in the first subgroup S1 and the conductive lines L1 connected to the second light-emitting elements 40 in the second subgroup S2 are separated by at least one group of second light-emitting elements 40 in the first direction X. Fig. 9 and Fig.12The display panel shown is described by taking the conductive line L1 connected to the second light emitting elements 40 in the first subgroup S1 and the conductive line L1 connected to the second light emitting elements 40 in the second subgroup S2 with one group of second light emitting elements 40 spaced apart as an example. Fig.19 The display panel shown is described by taking the conductive line L1 connected to the second light emitting elements 40 in the first subgroup S1 and the conductive line L1 connected to the second light emitting elements 40 in the second subgroup S2 with two groups of second light emitting elements 40 spaced apart as an example.

[0112] For example, the display panel includes at least two overlapping conductive lines L1, and overlapping portions of two of the at least two overlapping conductive lines L1 extend along the first direction X. Figures 19 to 22 , the conductive line L1 includes a portion P1 extending along the first direction X, and the portions P1 extending along the first direction X of different conductive lines L1 overlap. Fig. 9 As shown, the first conductive line L11 has a portion P11 extending along the first direction X, the second conductive line L12 has a portion P12 extending along the first direction X, and the third conductive line L13 has a portion P13 extending along the first direction X. Figures 19 to 22 , the first conductive line L11 and the third conductive line L13 have an overlapping portion P0. Figures 19 to 22 , a portion P12 of the second conductive line L12 extending along the first direction X does not overlap with a portion P11 of the first conductive line L11 extending along the first direction X, and a portion P12 of the second conductive line L12 extending along the first direction X does not overlap with a portion P13 of the third conductive line L13 extending along the first direction X.

[0113] For example, at least two insulating layers are provided between two overlapping conductive lines. Fig.23 As shown in FIG. 1 , at least two insulating layers are disposed between the two overlapping conductive lines L1. Fig.23 As shown in FIG. 1 , at least two insulating layers are disposed between the overlapping portion P0 of the two conductive lines L1. Fig.19 and Fig.23 As shown, the first conductive line L11 and the third conductive line L13 overlap in a direction perpendicular to the substrate (third direction Z). Fig.23 As shown, an insulating layer 403 and an insulating layer 404 are provided between the first conductive line L11 and the third conductive line L13. Fig.23 As shown, the insulating layer 405 is disposed on the third conductive line L13. For example, the first electrode of the light-emitting element is connected to the first conductive line L11 through a via hole penetrating the insulating layer 405, the insulating layer 404, and the insulating layer 403, the first electrode of the light-emitting element is connected to the second conductive line L12 through a via hole penetrating the insulating layer 405 and the insulating layer 404, and the first electrode of the light-emitting element is connected to the third conductive line L13 through a via hole penetrating the insulating layer 405.

[0114] For example, element A overlaps element B, or element A overlaps element B in a direction perpendicular to the substrate, which means that the orthographic projection of element A on the substrate overlaps the orthographic projection of element B on the substrate.

[0115] refer to Fig.19 , the multiple subgroups S also include a third subgroup S3, the first subgroup S1, the second subgroup S2 and the third subgroup S3 are arranged in sequence, and the portion PR of the conductive line L1 connected to the second light-emitting element 40 in the second subgroup S2 that passes through the virtual dividing line VL of the first display area R1 and the second display area R2 and the portion PR of the conductive line L1 connected to the second light-emitting element 40 in the third subgroup S3 that passes through the virtual dividing line VL of the first display area and the second display area are separated by at least one group of second light-emitting elements 40. Figures 8 to 17 A virtual dividing line VL is also shown. For example, the virtual dividing line VL may be a boundary line between the first display area R1 and the second display area R2. The virtual dividing line VL is a virtual line and may not exist in the final product.

[0116] refer to Fig.19 and Fig. 20 , a portion PR1 of the first conductive line L11 connected to the second light-emitting elements 40 in the second subgroup S2, which passes through a virtual dividing line VL between the first display area R1 and the second display area R2, and a portion PR1 of the first conductive line L11 connected to the second light-emitting elements 40 in the third subgroup S3, which passes through a virtual dividing line VL between the first display area R1 and the second display area R2, separate the two groups of second light-emitting elements 40.

[0117] refer to Fig.19 and Fig.21 , a portion PR2 of the second conductive line L12 connected to the second light-emitting elements 40 in the second subgroup S2, which passes through a virtual dividing line VL between the first display area R1 and the second display area R2, and a portion PR2 of the second conductive line L12 connected to the second light-emitting elements 40 in the third subgroup S3, which passes through a virtual dividing line VL between the first display area R1 and the second display area R2, separate the two groups of second light-emitting elements 40.

[0118] refer to Fig.19 and Fig. 22 A portion PR3 of the third conductive line L13 connected to the second light-emitting elements 40 in the second subgroup S2, which passes through a virtual dividing line VL between the first display area R1 and the second display area R2, and a portion PR3 of the third conductive line L13 connected to the second light-emitting elements 40 in the third subgroup S3, which passes through a virtual dividing line VL between the first display area R1 and the second display area R2, separate the two groups of second light-emitting elements 40.

[0119] refer to Figures 19 to 22, the plurality of second pixel circuits 20 are spaced apart and distributed between the plurality of first pixel circuits 10. In the same row of pixel units, the plurality of first pixel circuits 10 are disposed between two adjacent second pixel circuits 20.

[0120] refer to Figure 3 and Fig. 22 At least one first pixel circuit 10 among the multiple first pixel circuits 10 can be connected to at least one first light-emitting element 30 among the multiple first light-emitting elements 30, and the orthographic projection of at least one first pixel circuit 10 on the substrate substrate BS at least partially overlaps with the orthographic projection of at least one first light-emitting element 30 on the substrate substrate BS.

[0121] refer to Figure 3 and Fig. 22 At least one second pixel circuit 20 among the plurality of second pixel circuits 20 is connected to at least one second light emitting element 40 among the plurality of second light emitting elements 40 through at least one conductive line L1. Figure 3 and Fig. 22 , the orthographic projections of the plurality of second pixel circuits 20 on the base substrate BS do not overlap with the orthographic projections of the plurality of second light emitting elements 40 on the base substrate BS.

[0122] refer to Figures 9 to 23 The multiple conductive lines L1 include multiple first conductive lines L1 located in the first pattern layer LY1, multiple second conductive lines L1 located in the second pattern layer LY2, and multiple third conductive lines L1 located in the third pattern layer LY3. The first pattern layer LY1, the second pattern layer LY2, and the third pattern layer LY3 are arranged in sequence, and the orthographic projection of a first conductive line L1 located in the first pattern layer LY1 on the base substrate BS partially overlaps with the orthographic projection of a third conductive line L1 located in the third pattern layer LY3 on the base substrate BS.

[0123] For example, the first pattern layer LY1 , ​​the second pattern layer LY2 , and the third pattern layer LY3 are all transparent conductive layers.

[0124] For example, when there is not enough space for the conductive lines, the load on the conductive lines can be reduced by overlapping the conductive lines that are farther apart in the direction perpendicular to the substrate. For example, in the case of three pattern layers, the second conductive line L12 located in the middle is not overlapped with the first conductive line L11 as much as possible, and is not overlapped with the third conductive line L13 as much as possible. The first conductive line L11 and the third conductive line L13 that are farther apart in the vertical direction can overlap.

[0125] refer to Fig.12, the density of the first electrodes E1 in the second display area R2 is the same as the density of the first electrodes E1 in the first display area. That is, the resolution of the second display area R2 is the same as the resolution of the first display area, and the embodiments of the present disclosure include but are not limited to this.

[0136] For example, the display panel provided by the embodiment of the present disclosure is illustrated by taking the setting method of the conductive line of the first electrode in the first sub-area R21 connecting the upper left corner of the second display area R2 as an example, and the setting method of the conductive line connecting the first electrode in the second sub-area R22, the third sub-area R23, and the fourth sub-area R24 can be obtained through mirror processing.

For example, to facilitate layout design, adjacent portions PT of the conductive lines connected to the same subgroup S1 are separated by at least one pixel circuit in the first direction X. Of course, adjacent portions PT of the conductive lines connected to the same subgroup S1 may not be separated by pixel circuits in the first direction X.
