[0073] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention. See also: Figure 1 The display panel includes a first display area AA1 and a second display area AA2, the second display area AA2 at least partially surrounds the first display area AA1, and the light transmittance of the first display area AA1 is greater than that of the second display area AA2.

[0075] Specifically, the second display area AA2 can be located to one side of the first display area AA1, or it can partially or completely surround the first display area AA1. The first display area AA1 can serve as an under-display camera (UDC) area. The light transmittance of the first display area AA1 is greater than that of the second display area AA2. The location of the first display area AA1 can correspond to the location of the under-display sensor. Here, "corresponding" means that the orthographic projection of the under-display sensor on the display panel at least partially or completely overlaps with the first display area AA1. That is, the orthographic projection of the under-display sensor on the display panel is located within the first display area AA1, or entirely within the first display area AA1. This allows more light to pass through the first display area AA1 and be received by the sensor. For example, the sensor may include a camera device, a light sensor, an ultrasonic sensor, a fingerprint sensor, and a radar sensor, etc. The second display area AA2 can be a normal display area. The resolution of the first display area AA1 and the second display area AA2 can be the same or different. The shape of the first display area AA1 can be circular, rectangular, square, rhomboid, etc., without limitation.

[0076] Figure 2 This is a schematic diagram of a cross-sectional structure of a display panel AA' provided in an embodiment of the present invention. Referring to the figure, the display panel includes: a substrate 110; and a first wiring layer 310 disposed on one side of the substrate 110 and located in the first display area AA1.

[0077] Multiple light-emitting units are disposed on one side of the substrate 110, located in the first display area and the second display area. Each light-emitting unit includes a first electrode 131 and a second electrode 511.

[0078] Wherein, one of the traces in the first trace layer 310 is connected to at least two first electrodes 131 located in the first display area AA1, and / or, one of the traces in the first trace layer 310 is connected to at least two second electrodes 511 located in the first display area AA1.

[0079] Specifically, depending on the material of the substrate 110, the substrate 110 can be a flexible substrate 110, such as a polyimide substrate 110, or a rigid substrate 110, such as a glass substrate 110. The anode layer 130 is provided with a plurality of first electrodes 131, which are spaced apart. A light-emitting functional layer is provided within the pixel opening S1. The exposed first electrodes 131 within the pixel opening S1 are connected to the light-emitting functional layer 510. A second electrode 511 is provided on the side of the light-emitting functional layer away from the substrate 110. The first electrodes 131, the light-emitting functional layer, and the second electrode 511 form a light-emitting unit. The first electrode 131 can serve as the anode of the light-emitting unit and is connected to the driving circuit layer. The driving current generated in the driving circuit layer can provide a driving signal to the anode of the light-emitting unit. The second electrode can serve as the cathode of the light-emitting unit.

[0080] To improve the light transmittance of the first display area AA1, a first wiring layer 310 is formed on one side of the substrate 110. By using a patterned design, the first wiring layer 310 can form corresponding wirings. These wirings connect the first electrodes 131 between different light-emitting units within the first display area AA1, and / or connect the second electrodes 511 between different light-emitting units within the first display area AA1. This allows the light-emitting units to share anode and / or cathode signals, thereby reducing the number of anode and / or cathode wirings within the corresponding first display area AA1, which helps improve the light transmittance of the first display area AA1. For example, Figure 2 As shown, at least two first electrodes 131 of the first display area are connected through a trace in the first trace layer 310. That is, the first electrodes 130 of the light-emitting units are connected, which can realize the sharing of a set of anode signals and thus the sharing of a set of driving circuits. This can reduce the structural layout of the driving circuit and further improve the light transmittance of the first display area AA1.

[0081] In this embodiment of the invention, a first wiring layer is provided between the substrate and the isolation structure. The first wiring layer is used to connect at least two first electrodes and / or at least two second electrodes, so that the same driving signal can drive multiple light-emitting units in the first display area, thereby reducing the number of wirings in the first display area and improving the light transmittance of the first display area.

[0082] In some embodiments, the second electrode 511 can employ fine metal mask (FFM) technology, forming spaced second electrodes 511 in the first display area AA1 and / or the second display area AA2. At least two second electrodes 511 can be connected through a trace in the first wiring layer. That is, at least two second electrodes 511 are connected between light-emitting units, allowing them to share a set of cathode signals. This reduces the area of ​​the cathode obstructing the first display area AA1, further improving the light transmittance of the first display area AA1. In some cases, the first electrodes between different light-emitting units within the first display area AA1 can be connected through a second wiring structure according to wiring requirements. The light-emitting units can share anode signals, reducing the number of wires in the first display area and thus improving the light transmittance of the first display area.

[0083] In some embodiments, Figure 3 A schematic diagram of the cross-sectional structure of another display panel AA' provided in an embodiment of the present invention is shown below. Figure 3 The display panel also includes an isolation layer, including a plurality of first isolation structures 140 located in the first display area. The first isolation structures 140 enclose a first isolation opening. The second electrode of the light-emitting unit disposed in the first display area AA1 is located in the corresponding first isolation opening and is electrically connected to the corresponding first isolation structure 140. The first wiring layer includes at least one first wiring structure 311, and the at least one first wiring structure 311 connects at least two first isolation structures 140.

[0084] Specifically, the first isolation structure 140 encloses and forms a first isolation opening, which is connected to the pixel opening S1. The first isolation structure 140 is insulated from the first electrode 131 and connected to the second electrode, allowing the first isolation structure 140 to provide a cathode power signal to the second electrode 511. The first isolation structure 140 can be used as a mask when fabricating the light-emitting functional layer, thereby saving on the use of mask materials and reducing the manufacturing cost of the display panel. It also reduces the distance requirement between adjacent pixel openings S1, which is beneficial for increasing the pixel density of the display panel. Furthermore, the first isolation structure 140 can be used to form independent light-emitting units, and the performance of each light-emitting unit can be independently adjusted.

[0085] A first wiring layer 310 is disposed between the substrate 110 and the first isolation structure 140. The first wiring layer includes at least one first wiring structure. For example, a first wiring structure 311 is formed by patterning the first wiring layer 310. Different first isolation structures 140 are connected through the first wiring structure 311, so that electrical connections are formed between the first isolation structures 140, thereby realizing the cathode signal transmission of the first display area AA1. It should be noted that the first wiring layer 310 is insulated from other metal layers. In order to improve the light transmittance of the first display area AA1, the first wiring layer 310 can be made of a transparent conductive material, such as indium tin oxide (ITO). In this embodiment of the invention, a first wiring layer 310 is provided between the substrate and the isolation structure. The first wiring layer 310 is used to connect different first isolation structures 140, which enables the transmission of power signals in the first display area. Compared with the second electrode 511 using fine metal mask technology, which covers the entire cathode layer in the first display area AA1 and / or the second display area AA2, the spaced first isolation structures 140 can reduce the shading area in the first display area AA1, thereby improving the light transmittance of the first display area AA1.

[0086] Based on the above embodiments, the first isolation structure 140 of the first display area AA1 can also be an integral structure. That is, different first isolation structures 140 are connected to form a mesh-like first isolation structure 140. Since the second electrode is located in the corresponding first isolation opening and is electrically connected to the corresponding first isolation structure 140, the mesh-like first isolation structure 140 can provide cathode signal transmission for the first display area AA1. In some cases, the first electrodes between different light-emitting units in the first display area AA1 can be connected through the second wiring structure 410 according to wiring requirements. The light-emitting units can share a common anode signal, enabling the same driving signal to drive multiple light-emitting units in the first display area, reducing the number of wirings in the first display area and improving the light transmittance of the first display area.

[0087] See also Figure 3In some embodiments, at least one first trace structure includes a first trace structure 311, wherein the first trace structure 311 connects multiple first isolation structures 140. Specifically, an anode layer 130 is disposed between a substrate 110 and the first isolation structures 140. The anode layer 130 is provided with multiple spaced first electrodes 131. The orthographic projection of the first electrodes 131 on the substrate 110 overlaps with the orthographic projection of the pixel opening S1 on the substrate 110. The first electrodes 131 are exposed within the pixel opening S1, and different first electrodes 131 are insulated from each other. The first isolation structures 140 between at least two first electrodes 131 can be connected by the first trace structure 311. For example, the first isolation structures 140 are spaced apart, forming a gap region between them, which insulates the first electrodes 131 from each other. The first trace structure 311 can be disposed in the gap region insulated between the first electrodes 131, and the first trace structure 311 is insulated from the first electrodes 131. In some embodiments, the spacing between the first electrodes 131 coincides with the orthographic projection of the spacing between the first isolation structures 140, facilitating the connection of the first wiring layer 310 to the first isolation structure 140. For example, the first wiring layer 310 can be co-layered with the first electrodes 131, thereby reducing the number of film layers and the thickness of the display panel. The materials of the first wiring layer 310 and the anode layer 130 can also be the same, allowing for co-layer fabrication and reducing fabrication process steps.

[0088] A light-emitting functional layer is disposed within the pixel opening S1. A first electrode 131 exposed within the pixel opening S1 is connected to the light-emitting functional layer. A second electrode is disposed on the side of the light-emitting functional layer away from the substrate 110. A first isolation structure 140 is connected to the second electrode. The first electrode 131, the light-emitting functional layer, and the second electrode form a light-emitting unit. When the power supply methods for the first display area AA1 and the second display area AA2 are the same, for example, when one pixel driving circuit powers one light-emitting unit, the first electrode 131 of one light-emitting unit can be connected to one pixel driving circuit. In some embodiments, to further increase the light transmittance of the first display area AA1, a pixel driving circuit is not disposed in the first display area AA1, but a corresponding driving circuit layer is disposed in the second display area AA2, and multiple pixel driving circuits are disposed in the driving circuit layer of the second display area AA2. In the first display area AA1, at least one conductive layer 320 is disposed between the anode layer 130 and the substrate 110. The first electrode 131 of the light-emitting unit in the first display area AA1 is connected to one pixel driving circuit in the second display area AA2 through at least one conductive layer 320. The pixel driving circuit outputs a corresponding driving current to the connected light-emitting unit through the conductive layer 320. A first planarization layer 330 is also disposed between the anode layer 130 and at least one conductive layer 320. The first planarization layer 330 can planarize the surface of the conductive layer away from the substrate 110. For example, the material of the first planarization layer 330 can be an organic adhesive, which can ensure the planarization reliability of the first planarization layer 330. A first through-hole is disposed on the first planarization layer 330, and the anode layer 130 and the conductive layer 330 are connected through the first through-hole.

[0089] In some embodiments, Figure 4 A schematic diagram of another cross-sectional structure of the display panel AA' provided in an embodiment of the present invention is shown below. Figure 4 The display panel may include two conductive layers 320, which are stacked between the anode layer 130 and the substrate 110. A first electrode 131 is connected to at least one pixel driving circuit of the second display area AA2 through the two conductive layers 320. A first planarization layer 331 is disposed between the first conductive layer 321 and the anode layer 130, and a second planarization layer 332 is disposed between the first conductive layer 321 and the second conductive layer 322. A first through-hole is disposed on the first planarization layer 331, and a second through-hole is disposed on the second planarization layer 332. The anode layer 130 and the first conductive layer 321 are connected through the first through-hole, and the second conductive layer 322 and the first conductive layer 321 are connected through the second through-hole. By providing multiple conductive layers 320, the circuit space is increased, avoiding circuit congestion that could affect the light transmittance of the first display area. In some embodiments, the second through-hole may also penetrate the first planarization layer 331 and the second planarization layer 332, allowing the anode layer 130 to be directly connected to the second conductive layer 322 through the second through-hole.

[0090] In some embodiments, Figure 5 A schematic diagram of another cross-sectional structure of the display panel AA' provided in an embodiment of the present invention is shown below. Figure 5 The first wiring structure 311 is disposed on the side of the anode layer 130 near the substrate 110. For example, the first wiring structure 311 is disposed on the same layer as the first conductive layer 321 or the second conductive layer 322. In this embodiment of the invention, the first wiring layer 310 is disposed on the same layer as the first conductive layer 321. The first planarization layer 331 is provided with a corresponding first via. The first via penetrates the first wiring layer 310 and the insulating layer between the first isolation structure 140 and the anode layer 130. Different first isolation structures 140 and first wiring layers 310 are connected through corresponding first vias.

[0091] In some embodiments, Figure 6 This is a schematic diagram of a cross-sectional structure at the BB' position of a display panel provided in an embodiment of the present invention, in conjunction with... Figure 3 See Figure 6 At least one first routing structure includes a first routing structure 311, wherein the first routing structure 311 connects multiple first isolation structures 140. Specifically, in the first display area AA1, the first isolation structures 140 that are spaced apart can be interconnected through the first routing structure 311 of the first routing layer 310, thus enabling the transmission of regional cathode signals in the first display area.

[0092] Optionally, the first wiring structure 311 connects multiple first isolation structures 140 and the second electrode of the light-emitting unit disposed in the second display area AA2. That is, in the first display area AA1, the first wiring structure 311 forms an electrical connection between the first isolation structures 140. Between the first display area AA1 and the second display area AA2, the first wiring structure 311 connects to the second electrode of the light-emitting unit in the second display area AA2, thereby allowing the cathode signal from the second display area AA2 to be introduced into the first display area AA1. This eliminates the need to set up a line for introducing the cathode signal transmission in the first display area AA1, further reducing the number of wires in the first display area AA1. By using multiple first isolation structures 140 to connect to the second electrode of the light-emitting unit in the second display area AA2, the cathode signal can be accessed from all directions into the first display area AA1, reducing the influence of line resistance and improving display uniformity.

[0093] Optionally, see [link to relevant documentation] Figure 6The isolation layer also includes a second isolation structure 160 located in the second display area AA2. The second isolation structure 160 encloses and forms multiple second isolation openings. The second electrode of the light-emitting unit disposed in the second display area AA2 is located in the corresponding second isolation opening and is electrically connected to the second isolation structure. A first wiring structure connects the second isolation structure and the multiple first isolation structures. Specifically, the second isolation structure 160 encloses and forms second isolation openings, which are connected to the pixel openings of the second display area AA2. The second isolation structure 160 is insulated from the first electrode 131 and connected to the second electrode of the second display area AA2. A cathode power signal can be provided to the second electrode of the second display area AA2 through the second isolation structure 160. The second isolation structure 160 can be used as a mask when manufacturing the light-emitting functional layer, thereby saving the use of mask plates, reducing the manufacturing cost of the display panel, and reducing the distance requirement between adjacent pixel openings, which is beneficial to increasing the pixel density of the display panel. Between the first display area AA1 and the second display area AA2, a first wiring structure 311 is used to connect the second display area AA2 to a second isolation structure 160. This allows the cathode signal from the second display area AA2 to be introduced into the first display area AA1, eliminating the need for a line to transmit the cathode signal in the first display area AA1 and further reducing the number of wires in the first display area AA1. The first isolation structure 140 and the second isolation structure 160 can be fabricated on the same layer.

[0094] See also Figure 3-6The display panel further includes: a pixel defining layer 150 located on the side of the first wiring layer 310 and the first electrode 131 away from the substrate 110, and disposed in the first display area AA1 and the second display area AA2; an isolation layer located on the side of the pixel defining layer 150 away from the substrate 110; wherein, the pixel defining layer 150 disposed in the first display area AA1 includes vias, and at least one first wiring structure 311 connects at least two first isolation structures through the vias. Specifically, the pixel defining layer 150 is disposed between the anode layer 130 and the first isolation structure 140, and the pixel defining layer 150 can define the placement position of the light-emitting functional layer of the light-emitting unit in subsequent processes. In some embodiments, a spacing region S2 is provided between the spaced first isolation structures 140, between the first isolation structures 140 and the second isolation structures 160, and / or between the second isolation structures 160. The orthographic projection of the first electrode 131 onto the substrate 110 does not overlap with the orthographic projection of the spacing region S2 onto the substrate 110. The first wiring structure 311 is disposed within the spacing region S2, allowing it to be laid out using the space of the spacing region S2, avoiding the influence of the first electrode 131. Furthermore, the first wiring structure 311 is closest to the first isolation structures 140 at both ends of the spacing region S2 in the thickness direction, thereby reducing wiring difficulty. The pixel defining layer 150 covers the spacing region S2 between the first electrodes 131. A via is provided in the spacing region S2, and the first wiring structure 311 is connected to the first isolation structure 140 through the via.

[0095] In some embodiments, the first wiring layer 310 includes at least one first wiring structure 311 and a plurality of second wiring structures 410, wherein at least one first wiring structure 311 is connected to at least two second electrodes 511 located in the first display area AA1, and the second wiring structures 410 are connected to at least two first electrodes 311 located in the first display area AA1.

[0096] Specifically, in the first display area AA1, the second electrode 511 can be interconnected by at least one first wiring structure 311, and the first electrodes 311 can be connected by a second wiring structure 410. Thus, the connected light-emitting units in the first display area AA1 can share the anode and cathode signal lines, thereby reducing wiring and increasing the light transmittance of the first display area AA1.

[0097] For example, in the first display area AA1, at least two light-emitting units can be powered through a single pixel driving circuit, thereby reducing the number of pixel driving circuits and the number of connection lines between the first electrode 131 of the light-emitting unit and the pixel driving circuit, reducing wiring. When at least two light-emitting units are powered through a single pixel driving circuit, the corresponding first electrodes 131 of the light-emitting units need to be connected. The second electrodes between the light-emitting units can also be interconnected through the first wiring structure 311, thereby reducing the wiring of the cathode signal lines.

[0098] Based on this Figure 7 This is a schematic diagram of a cross-sectional structure of another display panel AA' provided in an embodiment of the present invention. Figure 8 A schematic diagram of another cross-sectional structure of the display panel AA' provided in an embodiment of the present invention is shown below. Figure 7 and Figure 8 The first wiring layer 310 also includes multiple second wiring structures 410. The second wiring structures 410 are disposed between the substrate 110 and the first isolation structure 140, and are insulated from the first electrodes 131. Each second wiring structure 410 is connected to at least two of the first electrodes 131. Other first electrodes 131 can also be connected via the second wiring structures 410 as needed. The second wiring structures 410 can be disposed on the surface of the first electrode 131 near the substrate 110 or away from the substrate 110. Overlapping between the second wiring structures 410 and the first electrodes 131 simplifies the connection process. The second wiring structures 410 can partially or completely cover the first electrodes 131. When the second wiring structure 410 partially covers the first electrodes 131, the overlap area between the second wiring structure 410 and the first electrodes 131 is increased, improving the stability of the drive current transmission. When the second wiring structure 410 completely covers the first electrode 131, the second wiring structure 410 covers the side of the first electrode 131 and can also serve as a protective layer for the first electrode 131, preventing the first electrode 131 from being oxidized and improving the reliability of the display panel. When the second wiring structure 410 completely covers the surface of the first electrode 131 away from the substrate 110, the second wiring structure 410 is exposed within the pixel opening S1, and the light-emitting functional layer is indirectly connected to the first electrode 131 through the second wiring structure 410. At least one of the connected first electrodes 131 is selected and connected to at least one pixel driving circuit of the second display area AA2 through the conductive layer 320. For example, the selection of the connected first electrode 131 can refer to the principle of proximity. For example, the first electrode 131 that is closer to the pixel driving circuit to be connected can be selected to be connected to the conductive layer, thereby reducing the wiring distance between the conductive layer and the pixel driving circuit. In some embodiments, two or more of the first electrodes 131 connected together in the same group can also be selected to be connected to the conductive layer to improve the stability of the driving current transmission.

[0099] In some embodiments, Figure 9 A schematic diagram of another cross-sectional structure of the display panel AA' provided in an embodiment of the present invention is shown below. Figure 9The second wiring structure 410 can also be disposed on the same layer as the first conductive layer 321 or the second conductive layer 322. In this embodiment of the invention, the second wiring structure 410 is disposed on the same layer as the first conductive layer 321. The first planarization layer 331 is provided with corresponding vias, and at least two first electrodes 131 and the second wiring structure 410 are connected through corresponding vias.

[0100] In some embodiments, the first wiring structure 311 and the second wiring structure 410 can be disposed in the same layer, wherein the second wiring structure 410 covers the side of the corresponding first electrode 131 facing away from the substrate 110. The first wiring structure 311 and the second wiring structure 410 can also be disposed in the same layer on the side of the first electrode 131 away from the substrate 110, wherein the second wiring structure 410 covers the side of the corresponding first electrode 131 facing the substrate 110. The first wiring structure 311 and the second wiring structure 410 can be made of the same material, such as ITO, to improve light transmittance. The first wiring structure 311 and the second wiring structure 410 can be disposed in different layers. For example, when two or more conductive layers are provided, the second wiring structure 410 can be disposed in the same layer as one of the conductive layers, and the first wiring structure 311 can be disposed in the same layer as another conductive layer.

[0101] Optionally, Figure 10 A schematic diagram of another cross-sectional structure of the display panel AA' provided in an embodiment of the present invention is shown below. Figure 8 and Figure 10 The first wiring structure 311 and the second wiring structure 410 can be on the same layer and spaced apart. During the fabrication process, only one corresponding mask needs to be set, and the mask type for other processes can remain unchanged. The first wiring structure 311 and the second wiring structure 410 can be fabricated simultaneously, which further simplifies the manufacturing process. Thus, by using a single first wiring layer 310 to connect the anode and cathode between the light-emitting units in the UDC region, the number of film layers can be reduced, and the thickness of the display panel can be decreased. The first wiring layer 310 can be set on the side of the first electrode 131 away from the substrate 110. For example, the first wiring layer 310 can be set adjacent to the first electrode 131. In the fabrication process, this means that the anode layer 130 is fabricated first, and then the first wiring layer 310 is fabricated. For example, there is a spacer region S2 between the first isolation structures 140, the orthographic projection of the first wiring structure 311 on the substrate 110 is located in the spacer region S2, and the second wiring structure 410 is disposed in the spacer region S2. The space of the spacer region S2 can be used for wiring, avoiding the influence of the first electrode 131. In the thickness direction, the first wiring structure 311 is closest to the first isolation structures 140 at both ends of the spacer region S2, thereby reducing the wiring difficulty.

[0102] In some embodiments, Figure 11This is a schematic diagram of a cross-sectional structure of another display panel AA' provided in an embodiment of the present invention. Figure 12 A schematic diagram of another cross-sectional structure of the display panel AA' provided in an embodiment of the present invention is shown below. Figure 11 and Figure 12 The first wiring layer 310 is disposed on the side of the first electrode 131 near the substrate 110. For example, the first wiring layer 310 is disposed adjacent to the first electrode 131. In the fabrication process, the first wiring layer 310 is fabricated first, and then the anode layer 130 is fabricated. For example, there is a spacer region S2 between the first isolation structures 140. The orthographic projection of the first wiring structure 311 on the substrate 110 is located in the spacer region S2. The second wiring structure 410 is disposed in the spacer region S2. The space of the spacer region S2 can be used for wiring, avoiding the influence of the first electrode 131. In the thickness direction, the first wiring structure 311 is closest to the first isolation structures 140 at both ends of the spacer region S2, thereby reducing the wiring difficulty.

[0103] In some embodiments, the pixel defining layer 150 covers the gap region S2 between the first electrodes 131. In the gap region S2, the pixel defining layer 150 has a via. The first isolation structure 140 is connected to the first isolation structure 140 through the via, thereby connecting different gap structures. The second wiring structure 410 covers the first electrode 131 and is connected to the first electrode 131 of another light-emitting unit via the gap region S2.

[0104] Figure 13 A schematic diagram of another cross-sectional structure of the display panel AA' provided in an embodiment of the present invention is shown below. Figure 13 The display panel also includes a light-emitting functional layer 520, which is disposed within the pixel opening S1 and is connected to the first electrode 131.

[0105] Specifically, a light-emitting functional layer 520 is disposed within the pixel opening S1. The first electrode 131 can serve as the anode of the light-emitting unit and is connected to the driving circuit layer 120 through the conductive layer 330. The driving circuit layer 120 includes multiple layers of stacked metal layers and insulating layers. Transistors, capacitors, and other devices are formed using the metal layers, along with their corresponding connections, thereby forming a pixel driving circuit. The driving current generated in the driving circuit layer 120 can provide a driving signal to the anode of the light-emitting unit.

[0106] See also Figure 13 The display panel also includes a second electrode layer 510, which includes a plurality of second electrodes 511. The second electrodes 511 are disposed on the side of the light-emitting functional layer 520 away from the substrate 110, and are connected to the adjacent first isolation structure 140. The first electrode 131, the light-emitting functional layer 520, and the second electrodes 511 form a light-emitting unit.

[0107] Specifically, the second electrode 511 can serve as the cathode of the light-emitting unit. The first electrode 131 generates holes according to the driving signal, and the second electrode 511 generates electrons according to the power supply signal. The holes and electrons move to the light-emitting functional layer 520 to generate a light source, thereby enabling the light-emitting unit to emit light.

[0108] It should be noted that, in other embodiments, in addition to the light-emitting layer, the light-emitting functional layer 520, along the direction from the first electrode 131 to the second electrode 511, may further include a hole injection layer, a hole transport layer, and an electron blocking layer stacked sequentially between the first electrode 131 and the light-emitting layer. The light-emitting functional layer 520 may also include a hole blocking layer, an electron transport layer, and an electron injection layer stacked sequentially between the light-emitting layer and the second electrode 511; this is not limited here.

[0109] See also Figure 13 The first isolation structure 140 includes a connecting portion 141 and a suspension portion 142. The suspension portion 142 is disposed on the side of the connecting portion 141 away from the substrate 110. The orthographic projection of the connecting portion 141 on the substrate 110 lies within the orthographic projection of the suspension portion 142 on the substrate 110. The second electrode 511 is in contact with the connecting portion 141. The connecting portion 141 and the suspension portion 142 form a suspended first isolation structure 140. When forming the display panel, the connecting portion 141 and the suspension portion 142 can serve as a mask, thereby reducing the spacing requirement between adjacent pixel openings S1 and increasing the pixel density of the display panel. The materials of the connecting portion 141 and the suspension portion 142 are both conductive materials, such as metal materials.

[0110] In some embodiments, the first electrode 131 layer includes a first sub-electrode layer, a second sub-electrode layer and a third sub-electrode layer stacked together, wherein the third sub-electrode layer is disposed on the side of the first sub-electrode layer away from the array substrate.

[0111] Specifically, the first electrode 131 layer serves as the anode of the light-emitting device and possesses excellent conductivity. When the light-emitting side of the display panel is located on the side of the light-emitting functional layer 520 away from the first electrode 131 layer, by setting the first sub-electrode layer, the second sub-electrode layer, and the third sub-electrode layer stacked together, the first electrode 131 layer can possess a certain degree of reflectivity while ensuring its excellent conductivity. This reflective property is used to reflect the light emitted by the light-emitting functional layer 520 to the light-emitting side, thereby improving the luminous efficiency of the light-emitting device.

[0112] In some embodiments, the material of the second sub-electrode layer includes silver; specifically, silver has good electrical conductivity and a certain degree of reflectivity, which meets the functional requirements of the first electrode 131 layer as the anode of the light-emitting device.

[0113] In some embodiments, the materials of the first sub-electrode layer and the third sub-electrode layer include indium tin oxide (ITO). Specifically, ITO is disposed on both sides of the second sub-electrode layer, which can protect the second sub-electrode layer, reduce the probability of silver in the second sub-electrode layer being oxidized, and at the same time ensure the light transmittance of the anode.

[0114] The light emission color of the light-emitting unit in the above embodiments can be selected according to the actual application scenario. Figure 14 This is a schematic diagram of the arrangement of light-emitting units in a portion of a display panel according to an embodiment of the present invention. See also: Figure 14 The display panel can include multiple pixels, and each pixel includes at least two light-emitting units. For example, each pixel can include three light-emitting units, and the light-emitting units emit red, blue, and green light respectively to achieve color display. As another example, a pixel can include four light-emitting units arranged in a pentile pattern, commonly referred to as having four light-emitting units: red (R), green (G), blue (B), and green (G). The arrangement of the four light-emitting units can be vertical, horizontal, staggered in the same direction, diamond-shaped, or square, etc., without specific limitations.

[0115] Combination Figure 14 and Figure 3 In some embodiments, at least one first wiring structure includes multiple first wiring structures 311, wherein the first wiring structure 311 connects to the first isolation structure corresponding to at least one light-emitting unit in an adjacent pixel. Specifically, a first wiring layer 310 is provided between the substrate 110 and the first isolation structure 140. The first wiring layer 310 includes at least one first wiring structure. For example, the first wiring structure 311 is formed by patterning the first wiring layer 310, and different first isolation structures 140 are connected by the first wiring structure 311, so that electrical connections are formed between the first isolation structures 140, thereby realizing the cathode signal transmission of the first display area AA1.

[0116] Optionally, multiple light-emitting units are arranged to form multiple first pixel rows and multiple second pixel rows. The first pixel rows and second pixel rows are arranged alternately in the first direction Y. The pixels include first pixels 640 and second pixels 650. The first pixels 640 are arranged in the first pixel rows along the second direction X, and the second pixels 650 are arranged in the second pixel rows along the second direction X. The first direction Y and the second direction X have an angle. The first wiring structure 311 connects the first isolation structure 140 corresponding to the light-emitting unit in at least one first pixel 640 and the first isolation structure 140 corresponding to the light-emitting unit in at least one second pixel 650.

[0117] Specifically, both the first display area AA1 and the second display area AA2 include a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit. For example, the first light-emitting color is red, the second light-emitting color is blue, and the third light-emitting color is green; or, the first light-emitting color is blue, the second light-emitting color is red, and the third light-emitting color is green. In this embodiment, the first light-emitting color is red, the second light-emitting color is blue, and the third light-emitting color is green. In this embodiment, taking the first direction Y as the column direction and the second direction X as the row direction, in the first display area AA1, the first isolation structures 140 corresponding to the light-emitting units in the first pixel 640 of the first pixel row and the second pixel 650 of the second pixel row can be connected in the first direction Y. In some embodiments, the first isolation structures 140 corresponding to the light-emitting units in the first pixel 640 of the first pixel row and the second pixel 650 of the second pixel row can be connected in the second direction X, thereby achieving connection between some of the first isolation structures 140 corresponding to the light-emitting units in the first pixel 640 and the second pixel 650, specifically driving the corresponding light-emitting units in the first pixel 640 and the second pixel 650. In order to improve the light emission uniformity of light-emitting units of the same color, the light emission colors of the light-emitting units corresponding to the first isolation structure 140 connected by the first wiring structure 311 are the same.

[0118] In some embodiments, the light-emitting units corresponding to the first isolation structure 140 connected by the first wiring structure 311 may have different light-emitting colors. For example, the first electrodes 311 of light-emitting units with the same light-emitting color are connected by the second connection structure 410. In this embodiment of the invention, the first isolation structures 140 corresponding to the light-emitting units in the first pixel 640 and the second pixel 650 are connected by the first wiring structure 311. In order to reduce the number of pixel driving circuits and the number of connection lines between the first electrode 131 of the light-emitting unit and the pixel driving circuit, the first electrodes 131 of at least two light-emitting units with the same light-emitting color can be connected by the second wiring structure 410, and the series-connected first electrodes 131 can be connected to the pixel driving circuit of the second display area AA2 through a conductive layer, thereby reducing the number of connection lines between the first electrode 131 and the pixel driving circuit, and realizing the driving of multiple light-emitting units under the same driving signal.

[0119] See also Figure 14 The multiple light-emitting units include a first color light-emitting unit 610, a second color light-emitting unit 620 and a third color light-emitting unit 630, wherein: the first pixel 640 and the second pixel 650 both include a first row and a second row, the first row includes the first color light-emitting unit 610 and the second color light-emitting unit 620 arranged in the second direction X, and the second row includes multiple third color light-emitting units 630 arranged in the second direction X.

[0120] In the first direction Y, the first color light-emitting unit 610 in the first pixel and the second color light-emitting unit 610 in the second pixel are arranged alternately.

[0121] In the first direction Y, the second color light-emitting unit 620 in the first pixel and the first color light-emitting unit 610 in the second pixel are arranged alternately.

[0122] Specifically, taking a partial area arrangement as an example, for instance, the first luminous color is red, the second luminous color is blue, and the third luminous color is green; or, the first luminous color is blue, the second luminous color is red, and the third luminous color is green. In this embodiment of the invention, the first luminous color is red, the second luminous color is blue, and the third luminous color is green as an example; for instance, the third luminous unit 630 is located on the extension line perpendicular to the middle line connecting the first luminous unit 610 and the second luminous unit 620 in adjacent rows, and the third luminous unit 630 is located on the extension line perpendicular to the middle line connecting the first luminous unit 610 and the second luminous unit 620 in adjacent columns, forming a pentile arrangement. That is, the pixel includes four luminous units (RGBG), and according to the power supply ratio between the pixel driving circuit and the pixel, the first electrodes 131 corresponding to at least two luminous units with the same luminous color are connected using the second connection structure 410. In this embodiment of the invention, the power supply ratio is 1:2. Therefore, in the first display area AA1, the first electrodes 131 of two red light-emitting units need to be connected through the second connection structure 410, the first electrodes 131 of two blue light-emitting units need to be connected through the second connection structure 410, and the first electrodes 131 of four green light-emitting units need to be connected through the second connection structure 410.

[0123] Specifically, a first wiring structure 311 can be provided between the first display area AA1 and the second display area AA2, connecting at least one first isolation structure 140 of the first display area AA1 with at least one first isolation structure 140 of the second display area AA2. Therefore, the cathode signal of the second display area AA2 can be introduced into the first display area AA1 without the need for a line to transmit the cathode signal in the first display area AA1, further reducing the wiring quantity of the first display area AA1. For example, by using the first wiring layer 310 to introduce the cathode signal of the second display area AA2 into the first display area AA1 around the first display area AA1, the cathode signal can be uniformly accessed from all directions into the first display area AA1, reducing the influence of line resistance and improving display uniformity.

[0124] Figure 15 This is a schematic diagram of the arrangement of light-emitting units in a portion of a display panel according to another embodiment of the present invention. See also... Figure 15In this embodiment of the invention, when the power supply ratio is 1:3, the first electrodes 131 of three red light-emitting units, three blue light-emitting units, and six green light-emitting units in the first display area AA1 are connected through the second connection structure 410. A corresponding first wiring structure 311 can be provided between the first display area AA1 and the second display area AA2, connecting at least one first isolation structure 140 of the first display area AA1 to at least one first isolation structure 140 of the second display area AA2. Therefore, the cathode signal of the second display area AA2 can be introduced into the first display area AA1 without the need for a line to transmit the cathode signal in the first display area AA1, further reducing the wiring quantity in the first display area AA1. For example, by using the first wiring layer 310 to introduce the cathode signal of the second display area AA2 into the first display area AA1 around the first display area AA1, the cathode signal can be uniformly accessed from all directions into the first display area AA1, reducing the influence of line resistance and improving display uniformity.

[0125] In some embodiments, both the first display area AA1 and the second display area AA2 include a first color-emitting unit 610, a second color-emitting unit 620, and a third color-emitting unit 630. The arrangement of the light-emitting units in the first display area AA1 can be the same as that in the second display area AA2. The orthographic projection of the first color-emitting unit 610 in the first display area AA1 onto the substrate 110 is smaller than that of the first color-emitting unit 610 in the second display area AA2 onto the substrate 110. Alternatively, the orthographic projection of the second color-emitting unit 620 in the first display area AA1 onto the substrate 110 is smaller than that of the second color-emitting unit 620 in the second display area AA2 onto the substrate 110. Alternatively, the orthographic projection of the third color-emitting unit 630 in the first display area AA1 onto the substrate 110 is smaller than that of the third color-emitting unit 630 in the second display area AA2 onto the substrate 110. This provides more light-transmitting area for the first display area AA1.

[0126] This invention also provides a display device. For example... Figure 16 As shown, the display device 20 includes a display panel 21 provided in any embodiment of the present invention.

[0127] Specifically, the display panel 21 is the display panel provided in any embodiment of the present invention. When the display device 20 includes the display panel provided in any embodiment of the present invention, it has the same beneficial effects as the display panel 21 provided in any embodiment of the present invention, which will not be described in detail here. The display device 20 can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, etc., and is not limited here.
