DETAILED DESCRIPTION OF THE INVENTION

[0061] Hereinafter, the features and exemplary embodiments of each aspect of the present application will be described in detail. In order to make the objectives, technical solutions, and advantages of the present application more clearly understood, the present application will be further described in detail below with reference to drawings and specific examples. It can be understood that the specific examples described herein are merely configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the examples is provided merely to illustrate examples of the present application and to provide a better understanding of the present application.

[0062] It should be noted that, in this specification, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another and do not necessarily require or imply that such an actual relationship or order exists between those entities or operations. Furthermore, the terms "comprises," "comprises," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or device that includes a set of elements not only includes those elements, but also other elements not expressly listed or that are inherent in such process, method, article, or device. Absent more limitations, elements qualified by the phrases "comprises," "comprises," or "comprises" do not exclude the presence of other identical elements in the process, method, article, or equipment that includes the elements.

[0063] As will be understood, when describing the structure of a component, a reference to one layer or region being "on" or "above" another layer or region may refer to being directly on top of the other layer or region, or may include other layers or regions between the other layer or region, and when the component is inverted, the layer or region would be "below" or "underneath" the other layer or region.

[0064] The embodiments of the present application provide a display panel and a display device, and each embodiment of the display panel and the display device will be described below with reference to the drawings.

[0065] 1 is a partial structural schematic diagram of a first conductive layer 200 and a second conductive layer 300 according to an embodiment of the present application. The X direction in the figure is a first predetermined direction, the Y direction in the figure is a second predetermined direction, and the Z direction in the figure is the thickness direction of the display panel 10. The area within the dotted frame in the figure may represent a hollow area 210a, and the area within the frame at the intersection of each signal line in the figure may represent an electrical connection area. For example, the area within the frame at the intersection of each signal line in the figure may represent a via connection area. If the intersection of each signal line in the figure is not framed, it can be assumed that the signal lines at that intersection are insulated from each other.

[0066] As shown in FIG. 1 , an embodiment of a first aspect of the present application provides a display panel 10, comprising: a first conductive layer 200 including a plurality of first signal lines 210 extending along a first predetermined direction X and distributed at intervals in a second predetermined direction Y; and a second conductive layer 300 including a plurality of second signal lines 310 shaped to extend along the second predetermined direction Y and distributed at intervals in the first predetermined direction X, the second conductive layer 300 being stacked on the first conductive layer 200 in a thickness direction Z of the display panel 10, wherein the first signal lines 210 include first segments 211 distributed at intervals in the first predetermined direction X, and the separated portions between adjacent first segments 211 form hollow regions 210 a, and the first segments 211 are connected to the second signal lines 310.

[0067] The display panel 10 according to the embodiment of the present application includes a first conductive layer 200 and a second conductive layer 300. The first conductive layer 200 includes a plurality of first signal lines 210 extending along a first predetermined direction X and spaced apart in a second predetermined direction Y. The first signal lines 210 include first segments 211 spaced apart in the first predetermined direction X. The first segments 211 are connected to second signal lines 310, so that both the first signal lines 210 and the second signal lines 310 can transmit signals in the display panel. A hollow region 210a is formed in the divided portion between adjacent first segments 211. The hollow region 210a in the first signal line 210 allows light to propagate through the hollow region 210a, effectively reducing light blocking by the first signal lines 210 and improving the light transmittance of the display panel 10.

[0068] In some alternative embodiments, at least two second signal lines 310 may be electrically connected via the first segments 211, for example, at least two second signal lines 310 adjacent to each other in the first predetermined direction X may be electrically connected via the first segments 211.

[0069] In this optional embodiment, the second conductive layer 300 and the first conductive layer 200 are stacked in the thickness direction Z of the display panel 10. The second conductive layer 300 includes a plurality of second signal lines 310 extending and shaped along the second predetermined direction Y and distributed at intervals in the first predetermined direction X. At least two second signal lines 310 adjacent to each other in the first predetermined direction X are electrically connected via the first segments 211, thereby effectively reducing the resistance during signal transmission. The first signal lines 210 and the second signal lines 310 electrically connected to each other also facilitate signal transmission in the display panel 10, thereby reducing the difficulty of signal control in the display panel 10.

[0070] In some optional embodiments, at least two first segments 211 may be electrically connected via a second signal line 310, for example, at least two first segments 211 adjacent to each other in the second predetermined direction Y may be electrically connected via a second signal line 310, and by improving the arrangement density of the signal lines, the resistance during signal transmission can be further reduced.

[0071] Alternatively, the second signal lines 310 adjacent to each other in the first direction X may be electrically connected via the first segments 211, thereby allowing the first signal lines 210 and the second signal lines 310 to be efficiently interleaved in a grid pattern. The first segments 211 of a single first signal line 210 are all disconnected by hollow regions 210a to facilitate light transmission, while the first segments 211 of a single first signal line 210 adjacent to each other in the first direction X may be electrically connected via the second signal line 310 connected thereto and the first segments 211 of the other first signal lines 210, thereby efficiently improving the arrangement density of the signal lines, facilitating signal transmission in the display panel 10, and reducing the difficulty of signal control in the display panel 10.

[0072] Optionally, adjacent second signal lines 310 in the first predetermined direction X may be electrically connected via at least two first segments 211, which further improves the signal line arrangement density and thereby further reduces the resistance during signal transmission.

[0073] FIG. 2 is a schematic diagram showing a partial structure of a first conductive layer 200 and a second conductive layer 300 according to another embodiment of the present invention.

[0074] In some embodiments of the present application, the length of the first segment 211 in the first predetermined direction X may be set in various ways, and the length of the first segment 211 in the first predetermined direction X may be set according to the specific resistance demand of the first signal line 210. Alternatively, as shown in FIG. 1 , the first segment 211 may be connected only between two adjacent second signal lines 310 in the first predetermined direction X, and the length of the first segment 211 in the first predetermined direction X may be equal to or greater than the distance between the two adjacent second signal lines 310 in the first predetermined direction X. Alternatively, as shown in FIG. 2 , the first segment 211 may be connected between two or more adjacent second signal lines 310 in the first predetermined direction X, and the length of the first segment 211 in the first predetermined direction X may be equal to or greater than twice the distance between the two adjacent second signal lines 310 in the first predetermined direction X.

[0075] In some embodiments of the present application, the length of hollow region 210a in first direction X may be determined in various ways, and the length of hollow region 210a in first direction X may be determined according to the light transmission requirements of display panel 10. For example, as shown in FIG. 1 , when no second signal line 310 is sandwiched between two adjacent first segments 211 in first direction X, the length of hollow region 210a in first direction X may be equal to or approximately smaller than the distance between two adjacent second signal lines 310 in first direction X. Alternatively, as shown in FIG. 2 , when a second signal line 310 is sandwiched between two adjacent first segments 211 in first direction X, the length of hollow region 210a in first direction X may be greater than the distance between two adjacent second signal lines 310 in first direction X.

[0076] In some alternative embodiments, the second signal line 310 may have various shapes. For example, the second signal line 310 may have a hollow region 210a similar to the first signal line 210, thereby reducing light blocking by the second signal line 310. Alternatively, as shown in FIGS. 1 and 2, the second signal line 310 may be shaped to extend continuously in the second predetermined direction Y, i.e., the second signal line 310 may not have a hollow region 210a. This allows the second signal line 310 to have a good layout density and thus effectively reduces the resistance of the second signal line 310. For convenience of explanation, the following embodiments will be described using an example in which the second signal line 310 does not have a hollow region 210a.

[0077] FIG. 3 is a structural schematic diagram of a display panel 10 according to an embodiment of the present invention.

[0078] As shown in FIG. 3, in an embodiment of the present application, the display panel 10 may have a first display area A1 and a second display area A2, where both the first display area A1 and the second display area A2 are used to realize light-emitting display.

[0079] Optionally, the light transmittance of the second display area A2 is greater than that of the first display area A1. Therefore, when the display panel 10 is applied to a display device, a photosensitive assembly for detecting light in the display device is provided correspondingly below the second display area A2. This prevents the second display area A2 from blocking light significantly, allowing the photosensitive assembly to detect light effectively. For example, the photosensitive assembly may include at least one of a distance sensor, a camera, an under-screen fingerprint recognition module, an infrared light emitting diode (IR-LED) proximity sensor, or other light-sensing assemblies.

[0080] Alternatively, hollow region 210a may be located in second display region A2 to effectively reduce the light blocking effect of first signal line 210 in second display region A2, thereby allowing second display region A2 to have good light transmittance. However, hollow region 210a does not have to be located in first display region A1, i.e., first signal line 210 in first display region A1 may have a large extension size, thereby reducing resistance in first display region A1 and improving reliability of signal transmission.

[0081] Alternatively, the first signal lines 210 and the second signal lines 310 located in the first display area A1 can have good continuity, i.e., the first signal lines 210 and the second signal lines 310 in the first display area A1 do not need to have hollow areas 210a, so that the first signal lines 210 and the second signal lines 310 in the first display area A1 can be interleaved to form a mesh shape with high density, so that the first signal lines 210 and the second signal lines 310 in the first display area A1 can have good arrangement density, and the resistance in the first display area A1 can be effectively reduced.

[0082] FIG. 4 is a partial cross-sectional view of a display panel 10 according to an embodiment of the present invention.

[0083] 4 , in some alternative embodiments, the display panel 10 further includes a base 110 and a substrate 100 disposed on one side of the base 110, and the substrate 100 may be disposed in various manners. Illustratively, the substrate 100 may include a transistor 170 on the base 110 side. Optionally, the transistor 170 may include a gate electrode 171 and a source-drain electrode 172 located on a side of the gate electrode 171 away from the base 110. Illustratively, the substrate 100 may further include a storage capacitor 180, and optionally, the storage capacitor 180 may include a first electrode plate 181 and a second electrode plate 182 located on a side of the first electrode plate 181 away from the base 110.

[0084] For example, the substrate 100 may further include a first insulating layer 120, a second insulating layer 130, and a third insulating layer 140 located on the side of the base 110 facing the transistor 170 and stacked in order on the base 110. The gate electrode 171 and the first electrode plate 181 may be provided in the same layer, for example, on the side of the first insulating layer 120 facing the base 110. The second electrode plate 182 is located between the first insulating layer 120 and the second insulating layer 130, and the source / drain electrode 172 is located between the second insulating layer 130 and the third insulating layer 140.

[0085] In the embodiments of the present application, various types of signals can be transmitted through the first signal line 210 and the second signal line 310. For example, the first signal line 210 and the second signal line 310 are used to transmit a reset signal or a positive power supply voltage signal. For convenience of explanation, the following embodiments will be described taking as an example the first signal line 210 and the second signal line 310 are used to transmit a reset signal.

[0086] Optionally, the transistor 170 includes a reset transistor, and at least one of the first signal line 210 and the second signal line 310 is connected to the reset transistor to transmit a reset signal thereto, for example, at least one of the first signal line 210 and the second signal line 310 is connected to the source / drain electrode 172 of the reset transistor to transmit a reset signal thereto. Optionally, the second signal line 310 may be connected to the reset transistor to transmit a reset signal thereto, and the second signal line 310 has good continuity in the second predetermined direction Y, making it easy to connect to the reset transistor corresponding to each sub-pixel, and the second signal line 310 can have a small resistance.

[0087] In some optional embodiments, the first conductive layer 200 and the second conductive layer 300 may be disposed on the substrate 100, and optionally, the electrical connection between the first signal line 210 and the second signal line 310 may be via-connection. The specific locations of the first conductive layer 200 and the second conductive layer 300 may be varied, and optionally, the first conductive layer 200 may be disposed in the same layer as the source / drain electrodes 172, so that the first conductive layer 200 can be manufactured in the same manufacturing process as the source / drain electrodes 172 of the transistor 170, thereby improving the manufacturing efficiency of the display panel 10.

[0088] Alternatively, the second conductive layer 300 may be located between the first conductive layer 200 and the base 110. For example, the second conductive layer 300 may be provided in the same layer as the gate electrode 171, which allows the second conductive layer 300 to be manufactured in the same manufacturing process as the gate electrode 171 of the transistor 170, thereby improving the manufacturing efficiency of the display panel 10. Also, for example, the second conductive layer 300 may be provided in the same layer as the second electrode plate 182, which allows the second conductive layer 300 and the second electrode plate 182 of the storage capacitor 180 to be manufactured in the same manufacturing process, thereby improving the manufacturing efficiency of the display panel 10.

[0089] Optionally, the second conductive layer 300 may be located on a side of the first conductive layer 200 that is away from the base 110, for example, the substrate 100 may further include a fourth insulating layer 150 that is located on a side of the third insulating layer 140 that is away from the base 110, and the second conductive layer 300 may be provided between the third insulating layer 140 and the fourth insulating layer 150 to facilitate placement of the second signal line 310.

[0090] FIG. 5 is a partial schematic structural diagram of an isolation structure 700 according to an embodiment of the present application.

[0091] As shown in Figures 4 and 5, in some optional embodiments, the display panel 10 may further include an isolation structure 700 located on one side of the substrate 100, having a light-transmitting opening 700b and at least two isolation openings 700a, and an emitting layer 900 including a light-emitting unit 910 located in the isolation opening 700a, wherein the projections in the thickness direction Z of at least some of the light-transmitting openings 700b and the projections in the thickness direction Z of the first segments 211 are spaced apart.

[0092] Optionally, the isolation structure 700 may have a mesh shape, and the isolation openings 700a and the light-transmitting openings 700b may be formed in hollow portions of the mesh-shaped isolation structure 700. Optionally, at least some of the light-transmitting openings 700b may be located between adjacent isolation openings 700a.

[0093] In these alternative embodiments, the light-emitting units 910 are used to contribute to the light-emitting display of the display panel 10, and are disposed within the isolation openings 700a formed in the isolation structure 700, such that the isolation structure 700 is used to define sub-pixels of the display panel 10. The isolation structure 700 is provided with light-transmitting openings 700b, and the projections of at least some of the light-transmitting openings 700b in the thickness direction Z are spaced apart from the projections of the first segments 211 in the thickness direction Z, i.e., the projections of at least some of the light-transmitting openings 700b in the thickness direction Z are not overlapped with the projections of the first segments 211 in the thickness direction Z. This allows light to efficiently propagate through the hollow region 210a and the light-transmitting openings 700b in the first signal line 210, thereby reducing the blocking of light passing through the hollow region 210a by the isolation structure 700 and improving the light transmittance of the display panel 10.

[0094] Alternatively, the projection of the light-transmitting opening 700b in the thickness direction Z may refer to an area surrounded by the projection of the inner wall of the isolation structure 700 that surrounds and forms the light-transmitting opening 700b in the thickness direction Z. Alternatively, the spacing between the projection of at least a portion of the light-transmitting opening 700b in the thickness direction Z and the projection of the first segment 211 in the thickness direction Z may refer to the hollow region 210a being provided corresponding to the light-transmitting opening 700b, thereby allowing light to propagate well through the hollow region 210a and the light-transmitting opening 700b.

[0095] Optionally, the number of hollow regions 210a and light-transmitting openings 700b may be plural, and here, optionally, the number of hollow regions 210a may be smaller than the number of light-transmitting openings 700b, that is, the projections of some light-transmitting openings 700b in the thickness direction Z may be arranged so as not to overlap with the projections of the first segments 211 in the thickness direction Z, and the projections of other light-transmitting openings 700b in the thickness direction Z may be arranged so as to at least partially overlap with the projections of the first segments 211 in the thickness direction Z, thereby allowing the first segments 211 to have a good size in the first predetermined direction X, and facilitating the first segments 211 to be electrically connected to at least two adjacent second signal lines 310 in the first predetermined direction X. Alternatively, the number of hollow regions 210a may be equal to the number of translucent openings 700b, and the projection of each translucent opening 700b in the thickness direction Z may be spaced apart from the projection of the first segment 211 in the thickness direction Z, thereby allowing light to propagate well through the hollow regions 210a and the translucent openings 700b.

[0096] Optionally, the projection of the second signal line 310 in the thickness direction Z and the projection of the light-transmitting opening 700b in the thickness direction Z do not overlap, i.e., the second signal line 310 can be arranged to bypass the light-transmitting opening 700b, so that light is less likely to be blocked by the second signal line 310 and can pass through the light-transmitting opening 700b well.

[0097] Optionally, the projection of the first signal line 210 in the thickness direction Z and the projection of the isolation opening 700a in the thickness direction Z do not overlap, so that the first signal line 210 can be positioned between adjacent subpixels, thereby reducing the placement impact of the first signal line 210 on other elements in the substrate 100 below the subpixels.

[0098] In some embodiments of the present application, the isolation structure 700 may be used to block the material of the light-emitting layer 900 during the manufacturing of the light-emitting layer 900 to realize sub-pixel division, where the configuration of the isolation structure 700 may be varied, and the shape of the isolation structure 700 may be any shape that can shield and block the material of the light-emitting layer 900 in the adjacent isolation opening 700a.

[0099] As shown in FIG. 4, in some optional embodiments, the isolation structure 700 may include a first isolation portion 710 and a second isolation portion 720 located on the side of the first isolation portion 710 away from the substrate 100, and the second isolation portion 720 may be provided protruding from the first isolation portion 710 toward the isolation opening 700a.

[0100] By arranging the second isolation portion 720 so as to protrude from the first isolation portion 710 toward the isolation opening 700a, when depositing the light-emitting layer 900 of the display panel 10, the second isolation portion 720 can block at least a portion of the material used to manufacture the light-emitting layer 900, thereby blocking the light-emitting layer 900 between adjacent subpixels, and also makes it easier to form multiple light-emitting units 910 spaced apart.As a result, when depositing the light-emitting layer 900 of the display panel 10, for example, there is no need to install a high-precision metal mask (Fine Metal Mask, FMM), thereby reducing the production and manufacturing costs of the display panel 10.

[0101] Optionally, in the direction away from the substrate 100, the display panel 10 further includes a first electrode layer 500 and a second electrode layer 800, where the first electrode layer 500 includes a first electrode 510 located on the side of the light-emitting unit 910 facing the substrate 100, and the second electrode layer 800 includes a second electrode 810 located on the side of the light-emitting unit 910 away from the substrate 100.

[0102] Optionally, the light-emitting unit 910 may include a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting structure, an electron injection layer (EIL), and an electron transport layer (ETL).

[0103] In these alternative embodiments, the first electrode layer 500 and the second electrode layer 800 may be pixel electrode layers of the display panel 10, and one of the first electrode 510 and the second electrode 810 may be an anode and the other may be a cathode to drive the light-emitting unit 910 to emit light. In the embodiments of the present application, the first electrode 510 is an anode of the display panel 10 and the second electrode 810 is a cathode of the display panel 10 as an example.

[0104] Alternatively, the material of the isolation structure 700 may include a conductive material, for example, the material of the first isolation portion 710 may include a conductive material, and the second electrodes 810 in adjacent isolation openings 700a are electrically connected via the isolation structure 700, i.e., the second electrodes 810 in adjacent isolation openings 700a are connected to each other via the isolation structure 700 to form a plane electrode, thereby facilitating control of the second electrodes 810 in the display panel 10.

[0105] Optionally, the display panel 10 further includes a pixel limiting portion 600, which is located between the isolation structure 700 and the first electrode 510. This makes it difficult for a short circuit to occur between the isolation structure 700 and the first electrode 510, i.e., makes it difficult for a short circuit to occur between the first electrode 510 and the second electrode 810 via the isolation structure 700, thereby improving the reliability of the light-emitting display of the display panel 10.

[0106] In some embodiments of the present application, the relative positions of the pixel limiting portion 600 and the isolation structure 700 may be arranged in various ways. For example, as shown in FIG. 4 , the isolation structure 700 may be arranged on the side of the pixel limiting portion 600 that is farther from the substrate 100, i.e., the isolation structure 700 may be arranged directly on the pixel limiting portion 600. Alternatively, for example, an accommodation groove may be formed in the pixel limiting portion 600, and at least a portion of the isolation structure 700 may be located in the accommodation groove. This prevents the isolation structure 700 from having an excessively large height compared to the substrate 100, thereby effectively reducing the thickness of the display panel 10.

[0107] In some embodiments, the transistor 170 may further include a drive transistor, which is used to transmit a drive current, where the drive current is used to flow through the first electrode 510 to drive the light-emitting unit 910 to emit light.

[0108] In some embodiments of the present application, the number of reset transistors connected to at least one of the first signal line 210 and the second signal line 310 may be multiple, and the reset transistors may be connected to some devices in the display panel 10 to transmit reset signals.

[0109] Optionally, some of the reset transistors are connected to the control end of the driving transistor to transmit a reset signal to the control end of the driving transistor to reset the control end of the driving transistor; for example, some of the reset transistors can be connected to the gate electrode 171 of the driving transistor to transmit a reset signal to the gate electrode 171 of the driving transistor.

[0110] Optionally, some of the reset transistors are connected to the output terminal of the driving transistor to transmit a reset signal to the output terminal of the driving transistor to reset the control terminal of the driving transistor; for example, some of the reset transistors can be connected to the source-drain electrode 172 of the driving transistor to transmit a reset signal to the source-drain electrode 172 of the driving transistor.

[0111] Optionally, some reset transistors are connected to the first electrodes 510 and are used to transmit reset signals to the first electrodes 510 to reset the first electrodes 510 .

[0112] FIG. 6 is a schematic diagram showing the partial structure of the first conductive layer 200, the second conductive layer 300, and the third conductive layer 400 according to an embodiment of the present invention.

[0113] As shown in FIG. 6 , in some optional embodiments, the display panel 10 further includes a third conductive layer 400, which includes a compensation signal line 410, and the projection of the compensation signal line 410 in the thickness direction Z does not overlap with the projection of the hollow region 210a in the thickness direction Z, where the compensation signal line 410 is shaped to extend along the first predetermined direction X, and the compensation signal line 410 is connected to the second signal line 310.

[0114] Alternatively, at least two second signal lines 310 may be electrically connected via a compensation signal line 410, for example, at least two second signal lines 310 adjacent to each other in the first predetermined direction X may be electrically connected via a compensation signal line 410.

[0115] In this optional embodiment, hollow regions 210a are provided in first signal lines 210, which affects the arrangement density and arrangement size of first signal lines 210 to a certain extent and tends to increase the resistance during signal transmission in first signal lines 210 and second signal lines 310, which tends to reduce the operational stability of display panel 10. Therefore, by providing third conductive layer 400 including compensation signal line 410 and electrically connecting compensation signal line 410 to second signal line 310, signals transmitted through first signal line 210 and second signal line 310 can also be transmitted via compensation signal line 410, thereby effectively mitigating the effect of increased resistance caused by providing hollow regions 210a in first signal line 210 and effectively reducing the resistance during signal transmission in first signal line 210 and second signal line 310.

[0116] Furthermore, by arranging the compensation signal line 410 so that its projection in the thickness direction Z does not overlap with the projection in the thickness direction Z of the hollow region 210a, the arrangement of the compensation signal line 410 is less likely to block the hollow region 210a in the thickness direction Z, which allows light to pass through the hollow region 210a efficiently, thereby improving the light transmittance of the display panel 10.

[0117] Optionally, the projection of the compensation signal line 410 in the thickness direction Z is arranged so as not to overlap with the projection of the light-transmitting opening 700b in the thickness direction Z, so that the installation of the compensation signal line 410 is less likely to block the light-transmitting opening 700b in the thickness direction Z, thereby allowing light to pass through the hollow region 210a and the light-transmitting opening 700b efficiently, and improving the light transmittance of the display panel 10.

[0118] In some embodiments of the present application, the position of the third conductive layer 400 may be varied, and optionally, the third conductive layer 400 may be disposed on the substrate 100 .

[0119] Optionally, the third conductive layer 400 may be located away from the base 110 of the first conductive layer 200 to reduce the influence of the arrangement of the compensation signal line 410 in the third conductive layer 400 on the arrangement of other devices on the substrate 100, and this also facilitates the arrangement of the compensation signal line 410 misaligned with the hollow region 210a and the light-transmitting opening 700b. For example, the display panel 10 may further include FIAA (Fanout In AA) wiring, and the third conductive layer 400 may be provided in the same layer as at least some of the FIAA wiring but insulated from each other. This allows the compensation signal line 410 to be manufactured in the same manufacturing process as the FIAA wiring, thereby facilitating improved manufacturing efficiency of the display panel 10. Specifically, the display panel 10 may further include a fifth insulating layer 160 located on a side of the fourth insulating layer 150 away from the base 110, and the third conductive layer 400 may be located between the fifth insulating layer 160 and the fourth insulating layer 150, where optionally, the fifth insulating layer 160 may be a planarization layer of the display panel 10.

[0120] FIG. 7 is a schematic diagram showing a partial structure of the third conductive layer 400 and the third signal line 190 according to the embodiment of the present application.

[0121] In some optional embodiments, the display panel 10 further includes a third signal line 190 that is insulated from the compensation signal line 410, and at least a portion of the third signal line 190 is provided in the same layer as the third conductive layer 400. Here, the third signal line 190 may be an FIAA wiring of the display panel 10, and for example, at least a portion of the third signal line 190 may be provided within the first display area A1 and / or the second display area A2.

[0122] Optionally, the third signal line 190 is used to transmit a negative power supply voltage signal. For example, the third signal line 190 may be electrically connected to the isolation structure 700 to transmit the negative power supply voltage signal. As an example, the display panel 10 further includes a non-display area A3, where at least a portion of the non-display area A3 may surround the periphery of the first display area A1 and / or the second display area A2, and the third signal line 190 may be partially disposed in the non-display area A3 and electrically connected to the isolation structure 700 in the non-display area A3.

[0123] Optionally, the third signal line 190 includes a first sub-signal line 191 and a second sub-signal line 192 connected to each other, the first sub-signal line 191 being provided in the same layer as the third conductive layer 400, and the second sub-signal line 192 being located between the third conductive layer 400 and the first conductive layer 200. For example, the first sub-signal line 191 may be located between the fifth insulating layer 160 and the fourth insulating layer 150, and the second sub-signal line 192 may be located between the fourth insulating layer 150 and the third insulating layer 140.

[0124] Optionally, the first sub-signal lines 191 are formed to extend along the first predetermined direction X and are spaced apart in the second predetermined direction Y, and the second sub-signal lines 192 are formed to extend along the second predetermined direction Y and are spaced apart in the first predetermined direction X.

[0125] In some alternative embodiments, the number of compensation signal lines 410 is the same as the number of hollow regions 210a, so that the impact on the resistance of signal transmission caused by each hollow region 210a in the first signal line 210 is improved by providing a corresponding compensation signal line 410. Also, by providing only the same number of compensation signal lines 410 as the number of hollow regions 210a, the number of compensation signal lines 410 installed is prevented from being too large, so that other devices can be installed closely between the fourth insulating layer 150 and the fifth insulating layer 160, for example, other signal lines can be installed closely, thereby reducing the resistance of the display panel 10.

[0126] Optionally, the position of the compensation signal line 410 may be determined based on the position of the hollow region 210a. Optionally, the compensation signal line 410 may be located close to the hollow region 210a, for example, on any side of the hollow region 210a in the second predetermined direction Y. This allows the compensation signal line 410 to be properly positioned relative to the position of each hollow region 210a, and the first signal line 210, the second signal line 310, and the compensation signal line 410 to be uniformly arranged, thereby allowing the display panel 10 to have a uniform resistance when transmitting signals.

[0127] Alternatively, as shown in FIG. 6, a compensation signal line 410 may be connected between the second signal lines 310 located on both sides of the hollow region 210a in the first predetermined direction X, i.e., the compensation signal line 410 may be provided between the second signal lines 310 corresponding to the hollow region 210a and not provided with the first segment 211 for realizing the electrical connection, thereby realizing the electrical connection.

[0128] FIG. 8 is a schematic diagram showing the partial structure of a first conductive layer 200, a second conductive layer 300, and a third conductive layer 400 according to another embodiment of the present invention.

[0129] Alternatively, the compensation signal line 410 may be electrically connected to a plurality of adjacent second signal lines 310 in the first predetermined direction X at the same time. For example, as shown in FIG. 8, if a second signal line 310 is further sandwiched between second signal lines 310 located on both sides of the hollow region 210a in the first predetermined direction X, the compensation signal line 410 connected between the second signal lines 310 located on both sides of the hollow region 210a may be connected to all of the second signal lines 310 further sandwiched between them. As a result, the compensation signal line 410 may be provided between and electrically connected to all of the second signal lines 310 that do not have first segments 211 for achieving electrical connection, corresponding to the hollow region 210a.

[0130] Optionally, the extension length of the compensation signal line 410 may be set according to the size of the hollow region 210a. For example, the size of the compensation signal line 410 in the first predetermined direction X may be equal to or greater than the size of the hollow region 210a in the first predetermined direction X, i.e., the size of the compensation signal line 410 in the first predetermined direction X may be equal to or greater than the distance between adjacent first segments 211 in the first predetermined direction X, thereby effectively mitigating the effect of increased resistance caused by providing the hollow region 210a in the first signal line 210.

[0131] Optionally, the material of the compensation signal line 410 may be the same as the material of the first signal line 210, for example, the material of the compensation signal line 410 may include aluminum and / or titanium. By using the same material as the first signal line 210, the resistance characteristics of the material of the compensation signal line 410 can be made similar to or the same as the resistance characteristics of the material of the first signal line 210, which effectively alleviates the effect of increased resistance caused by providing the hollow region 210a in the first signal line 210 and prevents the resistance of the display panel 10 from being significantly changed by providing the hollow region 210a.

[0132] 1 to 8, an embodiment of a first aspect of the present application further provides a display panel 10 including a substrate 100, an isolation structure 700 located on one side of the substrate 100, the isolation structure 700 having a light-transmitting opening 700b and at least two isolation openings 700a, an emitting layer 900 including a light-emitting unit 910 located in the isolation openings 700a, and a first conductive layer 200 disposed on the substrate 100, the first conductive layer 200 including a first signal line 210, the first signal line 210 having a hollow region 210a, and a projection of at least a portion of the light-transmitting openings 700b in the thickness direction Z and a projection of the first signal line 210 in the thickness direction Z being spaced apart.

[0133] In the display panel 10 according to the embodiment of the present application, the light-emitting units 910 are capable of participating in light emission for the display panel 10, and are disposed within the isolation openings 700a formed in the isolation structure 700, such that the isolation structure 700 can define sub-pixels of the display panel 10. The isolation structure 700 has light-transmitting openings 700b, the first signal lines 210 have hollow regions 210a, and the projections of at least some of the light-transmitting openings 700b in the thickness direction Z are spaced apart from the projections of the first segments 211 in the thickness direction Z. This allows light to efficiently pass through the light-transmitting openings 700b of the isolation structure 700 and the hollow regions 210a of the first signal lines 210, thereby reducing light blocking by the isolation structure 700 and the first signal lines 210 and improving the light transmittance of the display panel 10.

[0134] Optionally, the display panel 10 according to the first embodiment of the present application may be the display panel 10 according to any of the above embodiments. Therefore, the display panel 10 according to the embodiment of the present application may have the beneficial effects of the display panel 10 according to any of the above embodiments, and the description thereof will be omitted herein. For example, the substrate 100 may be the substrate 100 according to any of the above embodiments. For example, the light-emitting layer 900 may be the light-emitting layer 900 according to any of the above embodiments, and the display panel 10 may further include the first electrode layer 500 and the second electrode layer 800 according to any of the above embodiments. For example, the isolation structure 700 may be the isolation structure 700 according to any of the above embodiments, and the isolation structure 700 may include the first isolation portion 710 and the second isolation portion 720 according to any of the above embodiments, whereby the isolation structure 700 is used to block the material of the light-emitting layer 900 to realize the division of sub-pixels during the manufacturing of the light-emitting layer 900. For example, the first signal line 210 may be the first signal line 210 in any of the above embodiments, and the first signal line 210 is formed to extend along a first predetermined direction X and is spaced apart in a second predetermined direction Y. For example, the first signal line 210 is used to transmit a reset signal or a positive power supply voltage signal. The first signal line 210 may include first segments 211 spaced apart in the first predetermined direction X, and the separated portions between adjacent first segments 211 may form hollow regions 210a.

[0135] Optionally, the display panel 10 may further include a second conductive layer 300 in any of the above embodiments, and the second conductive layer 300 may be provided on the substrate 100 and stacked with the first conductive layer 200 in the thickness direction Z. As an example, the second conductive layer 300 may include second signal lines 310 electrically connected to the first signal lines 210, where the first signal lines 210 are formed to extend along the first predetermined direction X and are spaced apart in the second predetermined direction Y, and the second signal lines 310 are formed to extend along the second predetermined direction Y and are spaced apart in the first predetermined direction X.

[0136] Alternatively, at least two second signal lines 310 may be electrically connected via the first segments 211. For example, at least two second signal lines 310 adjacent to each other in the first predetermined direction X are electrically connected via the first segments 211, thereby effectively reducing the resistance during signal transmission. Furthermore, the first signal lines 210 and the second signal lines 310 electrically connected to each other also facilitate the transmission of signals in the display panel 10 and reduce the difficulty of controlling signals in the display panel 10.

[0137] Optionally, the display panel 10 may further include a third conductive layer 400 in any of the above embodiments, which may be disposed on the substrate 100, and which may include the compensation signal line 410 in any of the above embodiments. For example, the projection of the compensation signal line 410 in the thickness direction Z does not overlap with the projection of the hollow region 210a in the thickness direction Z, and the compensation signal line 410 is shaped to extend along the first predetermined direction X and connected to the second signal line 310.

[0138] Optionally, at least two second signal lines 310 are electrically connected via a compensation signal line 410, for example, at least two second signal lines 310 adjacent to each other in the first predetermined direction X are electrically connected via a compensation signal line 410.

[0139] Optionally, in the display panel 10 according to the embodiment of the present application, the placement positions, extension dimensions, electrical connection relationships, and material selection of the first signal line 210, the second signal line 310, and the compensation signal line 410 can all be set with reference to the display panel 10 according to any of the above embodiments.

[0140] An embodiment of the second aspect of the present application provides a display device including the display panel 10 of any of the above-described embodiments. Since the display device according to the embodiment of the second aspect of the present application includes the display panel 10 according to any of the above-described embodiments of the first aspect, the display device according to the embodiment of the second aspect of the present application has the beneficial effects of the display panel 10 according to any of the above-described embodiments of the first aspect, and the description thereof will be omitted here.

[0141] The display device in the embodiments of the present application includes, but is not limited to, devices with display capabilities such as mobile phones, personal digital assistants (abbreviated as PDA), tablet computers, e-books, televisions, door access devices, smart landlines, and consoles.

[0142] Optionally, the display panel 10 may include a first display area A1 and a second display area A2, where the light transmittance of the first display area A1 may be smaller than the light transmittance of the second display area A2. The display device may also include a photosensitive assembly for sensing light, which is provided corresponding to the second display area A2. Optionally, the photosensitive assembly may be provided corresponding to a hollow area 210a in the second display area A2. For example, the orthogonal projection of at least a portion of the photosensitive assembly on the substrate 100 may be located within the orthogonal projection of the hollow area 210a on the substrate 100, thereby facilitating the sensing of light by the photosensitive assembly through the hollow area 210a.

[0143] Optionally, the type of photosensitive assembly may be installed in various ways. For example, the photosensitive assembly may include at least one of a distance sensor, a camera, an under-screen fingerprint recognition module, an infrared light-emitting diode proximity sensor, or other light-sensitive assemblies.

[0144] According to the above-described embodiments of the present application, these embodiments do not describe all details in detail, and the present invention should not be limited to only the specific embodiments. From the above description, it is apparent that many modifications and variations are possible.
