Description

Technical Field

[0001] The present application relates to the field of display technologies, and in particular, to a display panel, a preparation method thereof, and a display device. Background Art

[0002] The OLED (Organic Light Emitting Diode) display panel is one of the hotspots in the current research field of display panels. Compared with the liquid crystal display panel, the OLED display panel has the advantages of low energy consumption, low cost, self-luminescence, wide viewing angle, and fast response speed.

[0003] However, when integrating the touch function by the Oncell method in the current OLED display panel, there are problems of high cost and large thickness. Summary of the Invention

[0004] Based on this, it is necessary to provide a display panel, a preparation method thereof, and a display device for solving the problems existing in the above display panel.

[0005] In a first aspect, an embodiment of the present application provides a display panel, including:

[0006] A substrate;

[0007] A partition structure is disposed on the substrate and defines a plurality of partition openings, has a plurality of first annular grooves, and is divided into a first structure body and a second structure body located in the first annular groove through the first annular groove;

[0008] A light-emitting functional layer includes a plurality of light-emitting structures, and the light-emitting structures are disposed in the partition openings;

[0009] An insulating layer covers a side of the partition structure facing away from the substrate;

[0010] A touch layer is disposed on a side of the insulating layer facing away from the partition structure, and includes a plurality of first touch structures arranged at intervals in the longitudinal direction and a plurality of second touch structures arranged at intervals in the transverse direction. The first touch structures and the second touch structures are independent of each other and form a bridge through the second structure body.

[0011] In the display panel provided by the embodiment of the present application, the partition structure is divided into a first structure body and a second structure body located in the first annular groove through the first annular groove. The independent first touch structures and second touch structures in the touch layer are bridged and mutually capacitive through the second structure body, so that the partition structure can be prepared by one mask and the touch layer can be prepared by one mask. The mutual capacitance of the first touch structures and the second touch structures can be realized only through the second structure body, and the touch layer is disposed on the insulating layer, thereby enabling Incell mutual-capacitance touch. The preparation cost of the above display panel is relatively low and the product thickness is relatively thin.

[0012] In one embodiment, the second structure is located inside the first structure, and the second structure and the first structure are spaced apart by the first annular groove;

[0013] Preferably, the second structure and the first structure are insulated from each other;

[0014] Preferably, the second structure extends in the second direction and is disposed between the light-emitting structures adjacent in the first direction.

[0015] In this way, it is convenient to arrange the partition structure.

[0016] In one embodiment, the positive projection of the second structure in the second direction at least covers the gap between the light-emitting structures adjacent in the second direction;

[0017] Preferably, the length of the second structure in the second direction is greater than the length of at least one of the light-emitting structures;

[0018] Preferably, a plurality of the second structures are arranged at intervals along the first direction;

[0020] Preferably, the positive projection of the second structure in the second direction intersects with the positive projection of the second touch structure in the second direction.

[0021] In this way, it is convenient for the light-emitting functional layer and the touch layer to make full use of the partition structure.

[0022] In one embodiment, the length of the first structure in the first direction is greater than the sum of the lengths of the plurality of light-emitting structures;

[0023] Preferably, the length of the first structure in the first direction is greater than the length of the light-emitting functional layer.

[0024] In this way, it is convenient to form the partition opening and avoid the introduction of the first annular groove from affecting the partition function of the partition structure.

[0025] In one embodiment, two of the first touch structures are arranged at intervals in the second direction above the first structure and extend above the second structure, and are respectively electrically connected to the second structure to form the bridge;

[0026] Preferably, along the second direction, the number of the second structures is less than that of the first touch structures;

[0027] Preferably, along the second direction, the number of the second structures is one, and the number of the first touch structures is two;

[0028] Preferably, along the second direction, the number of the second structures is N, where N is greater than 1, and the number of the first touch structures is N + 1.

[0029] In this way, the bridging connection between multiple first touch structures can be realized more conveniently and reliably.

[0030] In one embodiment, the second touch structure is disposed above the second structure along the first direction;

[0031] Preferably, along the second direction, on the same second structure, the second touch structure is located between the first touch structures;

[0032] Preferably, the first annular groove extends along the second direction, and the second touch structure extends above the first structure.

[0033] In this way, the mutual capacitance between the first touch structure and the second touch structure can be realized more conveniently and reliably.

[0034] In one embodiment, the first touch structure extends above the end of the second structure and is electrically connected above the end of the second structure to form the bridge;

[0035] Preferably, the projection profile of the second structure in the second direction does not exceed the projection profile of the light-emitting functional layer in the second direction;

[0036] Preferably, in the edge region of the partition structure along the second direction, the orthographic projection of the second structure in the second direction intersects with the orthographic projection of the partition opening in the second direction.

[0037] In this way, it can be ensured that the area for accommodating the second touch structure on the second structure is relatively large.

[0038] In one embodiment, there is at least one first annular groove in the second direction;

[0039] Preferably, the number of the first annular grooves in each second direction is one;

[0040] Preferably, the number of the first annular grooves in each second direction is multiple, and the multiple first annular grooves are arranged at intervals along the second direction;

[0041] Preferably, at least one first annular groove extends to the two side edge regions of the partition structure along the second direction.

[0044] Preferably, the second structure is prepared from a metal material;

[0045] Preferably, the material of the second structure is one or a combination of copper, silver, and gold.

[0046] This can facilitate the realization of the electrical connection between the first touch structure and the second structure.

[0047] In one embodiment, the cathodes of adjacent light-emitting structures are electrically connected through the first structure to provide a power signal, and the first touch structure is electrically connected through the second structure to provide a touch signal;

[0048] Preferably, the display panel further includes an IC, and the touch layer extends and routes from the side border of the display panel to the IC.

[0049] This can enable the touch layer to not need to time-division multiplex the cathode signal of the light-emitting structure, facilitating the realization of the touch function.

[0050] In one embodiment, the orthographic projection of the upper end portion of the first structure away from the substrate on the substrate covers the orthographic projection of the lower end portion of the first structure close to the substrate on the substrate;

[0051] Preferably, the cross-section of the first structure on the side away from the first annular groove in the third direction perpendicular to the substrate is one or a combination of a T shape and an inverted trapezoid.

[0052] This can ensure that the partition effect of the partition structure on adjacent light-emitting structures is not affected.

[0053] In one embodiment, the orthographic projection of the upper end portion of the second structure away from the substrate on the substrate covers the orthographic projection of the lower end portion of the second structure close to the substrate on the substrate;

[0054] Preferably, the cross-section of the second structure in the third direction perpendicular to the substrate is one or a combination of a T shape and an inverted trapezoid;

[0055] Preferably, along a third direction perpendicular to the substrate, the cross-section of the second structure is the same as that of the first structure.

[0056] In this way, it is convenient to fabricate the second structure and the first structure through a single etching process.

[0057] In one embodiment, the display panel further includes a first encapsulation layer covering the sidewalls of the light-emitting structure and the isolation structure;

[0058] Preferably, the insulating layer is located on a side of the first encapsulation layer away from the light-emitting structure;

[0059] Preferably, a second encapsulation layer and a third encapsulation layer are further provided on a side of the touch layer away from the insulating layer.

[0092] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0093] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0094] In this article, spatially related terms such as "upper" and "lower" are defined with reference to the accompanying drawings. Therefore, it will be understood that "upper" and "lower" are used interchangeably. It will be understood that when a layer is referred to as being "on" another layer, it can be directly formed on the other layer, or there can also be an intermediate layer. Therefore, it will be understood that when a layer is referred to as being "directly on" another layer, no intermediate layer is inserted therebetween.

[0095] In the accompanying drawings, for the sake of clarity, the dimensions of layers and regions may be exaggerated. It can be understood that when a layer or element is referred to as being "on" another layer or substrate, the layer or element can be directly on the other layer or substrate, or there can also be an intermediate layer. Additionally, it can also be understood that when a layer is referred to as being "between" two layers, the layer can be the only layer between the two layers, or there can also be one or more intermediate layers. Additionally, the same reference numerals always represent the same elements.

[0096] Hereinafter, although terms such as "first", "second", etc. may be used to describe various components, these components do not necessarily have to be limited to the above terms. The above terms are only used to distinguish one component from another. It will also be understood that expressions used in the singular form include the plural form, unless the singular form of the expression has a significantly different meaning in the context. In addition, in the following embodiments, it will also be understood that the terms "comprising" and / or "having" used herein indicate the presence of the stated features or components, but do not exclude the presence or addition of one or more other features or components.

[0097] In the following embodiments, when a layer, region or element is "connected", it can be interpreted that the layer, region or element is not only directly connected but also connected through other constituent elements placed therebetween. For example, when a layer, region, element, etc. are described as being connected or electrically connected, the layer, region, element, etc. can not only be directly connected or directly electrically connected, but can also be connected or electrically connected through another layer, region, element, etc. placed therebetween.

[0098] As used in the application documents, the term "and / or" includes any combination and all combinations of one or more of the related listed items. When an expression such as "at least one of..." is placed after a list of elements, it modifies the entire list of elements, rather than individual elements in the list.

[0099] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0100] It should also be understood that terms such as "comprise / include" or "have" etc. specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0101] It should also be understood that when interpreting an element, although not explicitly described, the element is interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "about", "approximate" or "substantially" may mean within one or more standard deviations, which is not limited herein.

[0102] In addition, in the specification, the phrase "schematic diagram of planar distribution" refers to the drawing when observing the target part from above, and the phrase "schematic cross-sectional diagram" refers to the drawing when observing the cross-section intercepted by vertically cutting the target part from the side.

[0103] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements are only drawn by way of example in the drawings and not necessarily to the actual scale.

[0104] As described in the background art, in the existing OLED display panel, the partition structure serves as the evaporation limit and the encapsulation limit of the light-emitting structure. During evaporation, the light-emitting layer and the cathode of the light-emitting structure are interrupted by the partition structure, and the cathode is electrically connected through the partition structure, making the OLED display panel easy to manufacture and reducing the thickness. However, in the existing OLED display panel, the touch layer integrates the touch function by the Oncell method. This method requires at least 4 mask etching operations during preparation, resulting in the technical problems of high cost and large stacked thickness, leading to a high cost and large product thickness of the OLED display panel.

[0105] Patent PCT / CN2023 / 134518, 202310759370.2, 202310740412.8, 202310707209.0, 202311346196.5 disclose related technical solutions of the isolation structure, the content of which is incorporated herein by reference for reference.

[0106] In view of the above problems, embodiments of the present application provide a display panel, a manufacturing method thereof, and a display device. By providing a first annular groove on the partition structure, the partition structure is divided into a first structure body and a second structure body located in the first annular groove through the first annular groove. The first touch structure and the second touch structure are independent of each other and are bridged and mutually capacitive through the second structure body. In this way, compared with the Oncell method in the prior art that integrates the touch function through four masks, in the embodiments of the present application, one mask for manufacturing the partition structure is improved, and then Incell mutual capacitive touch can be achieved through one mask, with lower manufacturing cost and thinner product thickness.

[0107] In a first aspect, referring to Figure 1 、 Figure 2 and Figure 3 embodiments of the present application provide a display panel 10, which includes a substrate 100, a partition structure 200, a light-emitting functional layer, an insulating layer 400, and a touch layer 500. The partition structure 200 is disposed on the substrate 100, and the partition structure 200 defines a plurality of partition openings 210. A plurality of first annular grooves 220 are formed on the partition structure 200, and the partition structure 200 is divided into a first structure body 230 and a second structure body 240 through the first annular grooves 220. The second structure body 240 is located in the first annular grooves 220. The light-emitting functional layer includes a plurality of light-emitting structures 300, and the light-emitting structures 300 are correspondingly disposed with the partition openings 210 and are disposed in the partition openings 210. The insulating layer 400 covers a side of the partition structure 200 facing away from the substrate 100. The touch layer 500 is disposed on a side of the insulating layer 400 facing away from the partition structure 200, and the touch layer 500 includes a plurality of first touch structures 510 and a plurality of second touch structures 520. The plurality of first touch structures 510 are spaced apart along a first direction Y, and the plurality of second touch structures 520 are spaced apart along a second direction X. The first direction Y intersects with the second direction X. The first touch structures 510 and the second touch structures 520 are independent of each other, and the first touch structures 510 and the second touch structures 520 are bridged and mutually capacitive through the second structure body 240.

[0108] It should be noted that the substrate 100 may be an array substrate 110, and the array substrate 110 has an array driving circuit. The partition structure 200 may be in a grid shape, multiple ring structures, etc., and the adjacent light-emitting structures 300 are separated by the partition structure 200. The multiple light-emitting structures 300 may include multiple first light-emitting structures 310 that emit red light, multiple second light-emitting structures 320 that emit blue light, and multiple third light-emitting structures 330 that emit green light, and the first light-emitting structures 310, the second light-emitting structures 320, and the third light-emitting structures 330 are alternately distributed. The light-emitting structure 300 includes an anode, a light-emitting layer, and a cathode. The materials of the anode and the cathode may be at least one of indium tin oxide and indium zinc oxide. The light-emitting layer may be an organic layer. The array driving circuit on the substrate 100 is electrically connected to the anode and is used to control the driving voltage applied between the anode and the cathode, so that the light-emitting structure 300 emits light and the display panel 10 performs a display function.

[0109] The material of the insulating layer 400 may be carbon oxide, nitrogen oxide, boron oxide, etc., and is formed by CVD deposition. The material of the touch layer 500 may be metal, metal oxide, a mixture containing metal, etc. One of the first touch structure 510 and the second touch structure 520 forms an inductive touch channel, and the other forms a driving touch channel. For the convenience of subsequent description, the first direction Y is defined as the longitudinal direction, the second direction X is defined as the transverse direction, the first direction Y is perpendicular to the second direction X, and the third direction Z is perpendicular to the substrate 100, and the third direction Z is perpendicular to the first direction Y and the second direction X. However, the protection scope of the present application is not limited thereto. In other embodiments, the first direction Y and the second direction X may also be interchanged.

[0110] In the display panel 10 provided by the embodiment of the present application, the partition structure 200 is divided into a first structure body 230 and a second structure body 240 located in the first annular groove 220 through the first annular groove 220. The mutually independent first touch structure 510 and the second touch structure 520 in the touch layer 500 are bridged and mutually capacitive through the second structure body 240, so that the partition structure 200 is prepared by one mask and the touch layer 500 is prepared by one mask. The mutual capacitance of the first touch structure 510 and the second touch structure 520 can be realized only through the second structure body 240, and the touch layer 500 is disposed on the insulating layer 400, so that the Incell mutual-capacitance touch can be realized. The manufacturing cost of the above display panel 10 is relatively low and the product thickness is relatively thin.

[0111] It can also be understood that: in the embodiments of the present application, the partition structure 200 is integrated into the first structure 230 to partition adjacent light-emitting structures 300, and the second structure 240 serves as a mutual capacitance bridging for the first touch structure 510 and the second touch structure 520. On the one hand, this makes the stack of the display panel 10 less and the product thickness thinner. On the other hand, only by making an adaptive adjustment to the mask for preparing the partition structure 200, the touch layer 500 can be prepared through one mask, with fewer manufacturing processes and lower preparation costs.

[0112] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 3 , the second structure 240 is located inside the first structure 230, and the second structure 240 and the first structure 230 are spaced apart by the first annular groove 220 to define a partition opening 210 through the first structure 230, and the partition opening 210 and the first annular groove 220 are spaced apart.

[0113] In one example, the second structure 240 and the first structure 230 are insulated from each other to prevent the second structure 240 and the first structure 230 from affecting each other.

[0114] In one example, the second structure 240 extends along the second direction X, and the second structure 240 is disposed between adjacent light-emitting structures 300 along the first direction Y, so as to facilitate the first touch structures 510 respectively extending above the second structure 240 to be spaced apart along the first direction Y.

[0115] In this way, by defining the positions of the second structure 240 and the first structure 230, the setting of the first annular groove 220 will not affect the partition opening 210, and the second structure 240 for realizing the electrical connection after the first touch structure 510 is bridged will not affect the partition effect of the first structure 230 on adjacent light-emitting structures 300, and through the above set positions, the setting of the partition structure 200 can be facilitated.

[0116] In one embodiment, referring to Figure 1 , the positive projection of the second structure 240 in the second direction X at least covers the gap between adjacent light-emitting structures 300 along the second direction X, so that the size of the second structure 240 in the second direction X is not less than the size of the first structure 230 between two adjacent light-emitting structures 300 along the second direction X.

[0117] In one example, the length of the second structure 240 in the second direction X can be greater than the length of one light-emitting structure 300, and the length of the second structure 240 in the second direction X can be greater than the length of multiple light-emitting structures 300 to adapt to different size forms of the second structure 240.

[0118] In one example, a plurality of second structures 240 are arranged at intervals along the first direction Y such that only one second structure 240 is arranged in the second direction X, and there are two first touch structures 510 in the second direction X. After being bridged by the second structure 240, these two first touch structures 510 are electrically connected.

[0119] In one example, a part of the second structures 240 are arranged at intervals along the first direction Y, and another part of the second structures 240 are arranged at intervals along the second direction X such that there are a plurality of second structures 240 in the second direction X, and there are a plurality of first touch structures 510 in the second direction X. Every two of these first touch structures 510 are electrically connected after being bridged by the second structure 240 to achieve the electrical connection of all the first touch structures 510 in the second direction X.

[0120] In one example, the orthographic projection of the second structure 240 in the second direction X intersects with the orthographic projection of the second touch structure 520 in the second direction X, so as to facilitate the arrangement of the second touch structure 520 on the second structure 240, thereby realizing the bridging mutual capacitance between the first touch structure 510 and the second touch structure 520.

[0121] In this way, by defining the positional relationship and dimensional relationship between the second structure 240 and the adjacent light-emitting structures 300 in the second direction X, the arrangement of the second structure 240 does not affect the definition of the partition opening 210 by the partition structure 200, and the adjacent light-emitting structures 300 are still partitioned by the first structure 230. The first touch structure 510 is arranged by using the second structure 240 between the adjacent light-emitting structures 300 along the first direction Y, and the second touch structure 520 is arranged by using the first structure 230 and the second structure 240 between the adjacent light-emitting structures 300 along the second direction X, which can facilitate the light-emitting functional layer and the touch layer 500 to make full use of the partition structure 200.

[0122] In one of the embodiments, referring to Figure 1 , the length of the first structure 230 in the first direction Y is greater than the sum of the lengths of the plurality of light-emitting structures 300 in the first direction Y, so that the first structure 230 partitions the plurality of light-emitting structures 300 respectively.

[0123] In one example, the length of the first structure 230 in the first direction Y is greater than the length of the light-emitting functional layer, so that the first structure 230 is a grid-like structure, and the first structure 230 partitions all the light-emitting structures 300 in the first direction Y respectively.

[0124] In this way, by defining the dimensional relationship between the first structure 230 and the light-emitting structure 300 in the first direction Y, the setting mode of the partition opening 210 in the first direction Y can be determined, which is convenient for the formation of the partition opening 210 and can avoid the influence of the introduction of the first annular groove 220 on the partition function of the partition structure 200.

[0125] In one embodiment, two first touch structures 510 are arranged above the first structure 230 at intervals in the second direction X, and the first touch structures 510 extend above the second structure 240. The two first touch structures 510 are respectively electrically connected to the second structure 240 to form a bridge, so as to realize the electrical connection after the bridging of the two first touch structures 510 through the second structure 240.

[0126] In one example, along the second direction X, the number of the second structures 240 is less than that of the first touch structures 510, so that both ends of the second structure 240 along the second direction X can be used to receive the first touch structures 510, and the structure is simple and the setting is convenient.

[0127] In one example, along the second direction X, the number of the second structures 240 is one, and the number of the first touch structures 510 is two. At this time, the first touch structures 510 are located at both ends of the insulating layer 400 along the second direction X, so as to further simplify the setting of the first touch structures 510 and the second structures 240.

[0128] In one example, along the second direction X, the number of the second structures 240 is N, N>1, and the number of the first touch structures 510 is N + 1. At this time, through this corresponding relationship, the corresponding design of one mask for preparing the partition structure 200 and another mask for preparing the touch layer 500 can be realized, which is convenient for the corresponding setting of the second structure 240 and the first touch structure 510.

[0129] In this way, by defining that each second structure 240 has two first touch structures 510 and at the same time defining the relative positional relationship between the first touch structures 510 and the partition structure 200, the bridging connection between multiple first touch structures 510 can be realized more conveniently and reliably.

[0130] In one embodiment, referring to Figure 1 and Figure 2 , the second touch structure 520 is arranged above the second structure 240 along the first direction Y, so as to facilitate the setting of the second touch structure 520.

[0131] In one example, along the second direction X, the second touch structure 520 on the same second structure body 240 is located between the first touch structures 510 to facilitate the relative arrangement of the second touch structure 520 and the first touch structure 510, and the second touch structure 520 and the first touch structure 510 on the same second structure body 240 are arranged with an interval therebetween.

[0132] In one example, the first annular groove 220 extends along the second direction X, and the second touch structure 520 extends above the first structure 230, so that a plurality of second structures 240 are arranged at intervals along the first direction Y, and the first structure 230 is provided between the second structures 240. The second touch structure 520 extends above the first structure 230, so that the second touch structure 520 crosses the first annular groove 220 and covers the second structure 240 and the first structure 230, thereby ensuring the continuity of the second touch structure 520 in the first direction Y.

[0133] In this way, multiple second touch structures 520, multiple first touch structures 510, and multiple second structural bodies 240 form a grid structure, and each intersection point of the grid structure corresponds to a touch structure along the second direction X, a second structural body 240, and a first touch structure 510 along the first direction Y, so that a unique touch position can be determined, thereby making it easier to achieve the bridging mutual capacitance of the first touch structure 510 and the second touch structure 520, and the reliability and accuracy of the bridging mutual capacitance of the first touch structure 510 and the second touch structure 520 are high.

[0134] Continue to refer to Figure 2 In one embodiment, the first touch structure 510 extends to the upper end of the second structure 240, and the first touch structure 510 is electrically connected to the upper end of the second structure 240 to form a bridge, so that the first touch structure 510 crosses the first ring groove 220 to cover the first structure 230 and the second structure 240, and the first touch structure 510 and the second structure 240 are electrically connected after the bridge to achieve signal transmission. In the specific setting, the area of ​​the first touch structure 510 above the end of the second structure 240 is at least enough to ensure the electrical connection.

[0135] In one example, the projection outline of the second structure 240 in the second direction X does not exceed the projection outline of the light-emitting functional layer in the second direction X, so that there is sufficient space in the second direction X to arrange the first annular groove 220, ensuring that the area of ​​the first structure 230 at both ends in the second direction X is suitable for setting the first touch structure 510, thereby improving the reliability of the setting of the first touch structure 510.

[0136] In one example, in the edge region of the partition structure 200 along the second direction X, the positive projection of the second structural body 240 in the second direction X intersects with the positive projection of the partition opening 210 in the second direction X, so that the second structural body 240 can carry the second touch structure 520 between the two adjacent outermost light-emitting structures 300, thereby making the size of the second structural body 240 relatively large and capable of accommodating more second touch structures 520 to improve the touch accuracy of the display panel 10.

[0137] In this way, by defining that the first touch structure 510 is attached above the end of the second structural body 240 and the first touch structure 510 is electrically connected above the end of the second structural body 240 to leave more areas for arranging the second touch structure 520, it can be ensured that the area for accommodating the second touch structure 520 on the second structural body 240 is relatively large, facilitating the arrangement of the second touch structure 520.

[0138] Refer to Figure 4 and Figure 5 , in one embodiment, there is at least one first annular groove 220 in the second direction X. When specifically arranged, the number of first annular grooves 220 corresponding to the plurality of first structural bodies 230 can be the same to facilitate the arrangement of the first annular groove 220; the number of first annular grooves 220 corresponding to the plurality of first structural bodies 230 can be different to adapt to different display panels 10.

[0139] In one example, the number of first annular grooves 220 in the second direction X is one to facilitate the arrangement of the first annular groove 220, and further make the structure of the partition structure 200 simple and stable.

[0140] In one example, the number of first annular grooves 220 in the second direction X is multiple, and the multiple first annular grooves 220 are arranged at intervals along the second direction X to facilitate obtaining the partition structure 200 through one mask, improving the structural accuracy and reliability of the mask.

[0141] In one example, at least one first annular groove 220 extends to the two side edge regions of the partition structure 200 along the second direction X, so that in the second direction X, the edge first annular groove 220 penetrates into the two side edge regions of the partition structure 200 along the second direction X, and further makes the size of the second structural body 240 in the second direction X relatively large.

[0142] In this way, by defining the number of first annular grooves 220 in the second direction X to make the first annular grooves 220 evenly arranged on the partition structure 200 in the second direction X, it is convenient to arrange the first annular grooves 220.

[0143] Refer to Figure 2 and Figure 5, in one embodiment, the second structure 240 includes a conductive material. The insulating layer 400 has a plurality of first vias 410 above the second structure 240, and each first via 410 exposes a part of the second structure 240. The first touch structure 510 is in contact with the second structure 240 exposed by a first via 410 to form a bridge, so as to realize the electrical connection between the first touch structure 510 and the second structure 240.

[0144] In one example, the second structure 240 is prepared from a metal material, and the metal material here can be a material with a relatively small resistance, and the material of the second structure 240 can be the same as the material of the touch layer 500.

[0145] In one example, the material of the second structure 240 can be one of copper, silver, and gold, and the material of the second structure 240 can also be a combination of multiple of copper, silver, and gold. Of course, the material of the second structure 240 is not limited thereto, and it can also be other materials that can meet the requirements. For example, it can be one or a combination of molybdenum, aluminum, and cobalt.

[0146] In this way, by defining the second structure 240 as a conductive structure, the first touch structure 510 and the second structure 240 are in contact through the first vias 410 on the insulating layer 400, so that the electrical connection between the first touch structure 510 and the second structure 240 can be realized more conveniently, which is easy to manufacture and has a lower cost.

[0147] Continue to refer to Figure 2 and Figure 5 , in one embodiment, the cathodes of adjacent light-emitting structures 300 are electrically connected through the first structure 230 to provide a power signal, so as to facilitate the unified control of the cathodes of all light-emitting structures 300. The first touch structure 510 provides a touch signal through the electrical connection of the second structure 240, so as to realize the independent control of the cathodes of adjacent light-emitting structures 300 and the first touch structure 510.

[0148] In one example, the display panel 10 further includes an IC. The touch layer 500 extends the wiring from the side border of the display panel 10 to the IC. The second structure 240 is electrically connected to the IC, and the second touch structure 520 is electrically connected to the IC, so as to control the first touch structure 510 and the second touch structure 520 respectively through the IC, so as to reduce the product thickness while realizing the electrical connection between the IC and the first touch structure 510.

[0149] In this way, the first structure 230 provides an electrical signal to the cathode of the light-emitting structure 300, the IC provides an electrical signal to the first touch structure 510 through the second structure 240, the IC provides an electrical signal to the second touch structure 520, and the IC controls the first touch structure 510 and the second touch structure 520 to operate independently of each other, so that the touch layer 500 does not need to time-share the cathode signal of the light-emitting structure 300, thereby facilitating the realization of the touch function.

[0150] It can also be understood that: the embodiment of the present application sets the first structure 230, the second structure 240, and the second touch structure 520 to be independently controlled from each other, so as to achieve independent control between the cathode of the light-emitting structure 300, the first touch structure 510, and the second touch structure 520. Compared with the prior art in which the touch function and the display function are controlled by timing coordination due to the time-sharing multiplexing of the cathode signal by the touch layer, the control logic is relatively simple and easy to implement.

[0151] Reference Figure 2 as well as Figure 5 In one embodiment, the orthographic projection of the upper end of the first structure 230 away from the substrate 100 on the substrate 100 covers the orthographic projection of the lower end of the first structure 230 close to the substrate 100 on the substrate 100. In a specific configuration, the first structure 230 includes an isolating portion and a blocking portion, the blocking portion is arranged above the isolating portion, the blocking portion is formed by the upper end of the first structure 230, and the isolating portion is formed by the lower end of the first structure 230. The isolating portion and the blocking portion can be integrally formed or can be prepared by multiple stacking.

[0152] In one example, the cross-section of the first structure 230 along the third direction Z perpendicular to the substrate 100 on the side away from the first annular groove 220 can be one of a T-shape and an inverted trapezoid, and the cross-section of the first structure 230 along the third direction Z perpendicular to the substrate 100 on the side away from the first annular groove 220 can also be a combination of a T-shape and an inverted trapezoid.

[0153] In this way, the light-emitting layer of the adjacent light-emitting structure 300 is separated by the lower end of the first structure 230, and the cathode of the adjacent light-emitting structure 300 is separated by the upper end of the first structure 230, so that although the first annular groove 220 is set on the partition structure 200, it can be ensured that the partition effect of the partition structure 200 on the adjacent light-emitting structure 300 is not affected.

[0154] Reference Figure 2 as well as Figure 5 In one embodiment, the orthographic projection of the upper end of the second structure 240 away from the substrate 100 on the substrate 100 covers the orthographic projection of the lower end of the second structure 240 close to the substrate 100 on the substrate 100 .

[0155] In one example, the cross-section of the second structure 240 along the third direction Z perpendicular to the substrate 100 may be one of a T shape and an inverted trapezoid, or may also be a combination of a T shape and an inverted trapezoid.

[0156] In one example, along the third direction Z perpendicular to the substrate 100, the cross-section of the second structure 240 is the same as that of the first structure 230.

[0157] In this way, by defining both the second structure 240 and the first structure 230 to have a structure with a larger upper end and a smaller lower end, the first structure 230 and the second structure 240 can be formed by one mask etching. During the etching process, an undercut structure is formed for the first structure 230 and the second structure 240, facilitating the preparation of the second structure 240 and the first structure 230 through a single etching process.

[0158] In one of the embodiments, referring to Figure 3 , the display panel 10 further includes a first encapsulation layer 610 that covers the sidewalls of the light-emitting structure 300 and the isolation structure for protecting the light-emitting structure 300. Specifically, the first encapsulation layer 610 is prepared by chemical vapor deposition (CVD).

[0159] In one example, the insulating layer 400 is located on the side of the first encapsulation layer 610 away from the light-emitting structure 300. On the one hand, it facilitates the setting of the insulating layer 400 and ensures the insulation effect. On the other hand, it can further improve the protection effect on the light-emitting structure 300 by means of the insulating layer 400.

[0160] In one example, a second encapsulation layer 620 and a third encapsulation layer 630 are further provided on the side of the touch layer 500 away from the insulating layer 400 for protecting the touch layer 500 and further protecting the light-emitting structure 300.

[0161] In this way, through the setting of the first encapsulation layer 610, the water and oxygen path entering the light-emitting structure 300 from the side of the touch layer 500 is cut off, thereby reducing the amount of water and oxygen that can reach the light-emitting structure 300, and thus improving the water and oxygen resistance function of the display panel 10.

[0162] Second, referring to Figure 1 , Figure 2 and Figure 3The embodiment of the present application provides a display panel 10, which includes a substrate 100, a partition structure 200, a light-emitting functional layer, an insulating layer 400 and a touch layer 500. The partition structure 200 is disposed on the substrate 100, and the partition structure 200 defines a plurality of partition openings 210. A plurality of first annular grooves 220 are provided on the partition structure 200, and the partition structure 200 is divided into a first structure body 230 and a second structure body 240 by the first annular grooves 220, and the second structure body 240 is located in the first annular grooves 220. The light-emitting functional layer includes a plurality of light-emitting structures 300, and the light-emitting structures 300 are disposed corresponding to the partition openings 210, and the light-emitting structures 300 are disposed in the partition openings 210. The insulating layer 400 covers the side of the partition structure 200 away from the substrate 100. The touch layer 500 is disposed on a side of the insulating layer 400 away from the partition structure 200 , and the touch layer 500 includes a plurality of first touch structures 510 and a plurality of second touch structures 520 .

[0163] At least two first touch structures extend along the second direction and are spaced apart, and the second touch structure extends along the first direction. The projections of the at least two first touch structures spaced apart along the second direction and the second structure on the substrate are connected into a straight line and intersect with the projections of the second touch structure on the substrate.

[0164] Thirdly, refer to Figure 6 , an embodiment of the present application provides a method for preparing a display panel, comprising:

[0165] S100: providing a substrate; illustratively, the substrate may be an array substrate.

[0166] S200: forming a partition structure on the substrate, wherein the partition structure defines a plurality of partition openings, a plurality of first annular grooves are formed on the partition structure, and the partition structure is divided into a first structure body and a second structure body by the first annular grooves, wherein the second structure body is located in the first annular grooves. Exemplarily, a layer of partition material is deposited on the substrate, and then the partition structure is etched out through a mask.

[0167] S300: forming a plurality of light-emitting structures and an insulating layer on a substrate, wherein the light-emitting structure is disposed in a partition opening, and the insulating layer covers a side of the partition structure facing away from the substrate; illustratively, a first conductive material layer, a light-emitting material layer, a second conductive material layer and an insulating material layer can be sequentially evaporated on the entire surface, and then patterned to form a plurality of first light-emitting structures and a first insulating unit, and the above preparation method is repeated to respectively prepare a second light-emitting structure and a second insulating unit and a third light-emitting structure and a third insulating unit, and the first insulating unit, the second insulating unit and the third insulating unit constitute an insulating layer.

[0168] S400: Form a touch layer on the substrate. The touch layer is disposed on the side of the insulating layer away from the partition structure, and the touch layer includes a plurality of first touch structures spaced along a first direction and a plurality of second touch structures spaced along a second direction intersecting the first direction. The first touch structures and the second touch structures are independent of each other, and the first touch structures and the second touch structures are bridged and capacitively coupled through a second structure. Exemplarily, deposit touch materials on the side of the insulating layer away from the partition structure, and then etch the touch layer through a mask.

[0169] In the method for manufacturing a display panel provided by an embodiment of the present application, the partition structure is divided into a first structure and a second structure located in the first annular groove through the first annular groove. The independent first touch structures and second touch structures in the touch layer are bridged and capacitively coupled through the second structure, so that the partition structure is fabricated through one mask and the touch layer is fabricated through one mask. The capacitive coupling of the first touch structures and the second touch structures can be achieved only through the second structure, and the touch layer is disposed on the insulating layer, thereby enabling Incell capacitive touch.

[0173] The display device provided by the embodiment of the present application divides the partition structure into a first structure body and a second structure body located in the first annular groove through the first annular groove.
