[0112] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present application are given 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, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present application more thorough and comprehensive.
[0113] 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.
[0114] In this document, spatially relative 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.
[0115] In the accompanying drawings, in order to clearly illustrate, 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.
[0116] Hereinafter, although terms such as "first", "second", etc. can 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 an expression used in the singular form includes 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.
[0117] 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.
[0118] 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 located after a list of elements, it modifies the entire list of elements rather than individual elements in the list.
[0119] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application pertains. 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.
[0120] It should also be understood that terms such as "comprises / include" or "has" specify the presence of the stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.
[0121] 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", "approximately", or "substantially" may mean within one or more standard deviations, which is not limited herein.
[0122] 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.
[0123] 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.
[0124] 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 stack thickness, leading to a high cost and large product thickness of the OLED display panel.
[0125] In view of the above problems, embodiments of the present application provide a display panel, a manufacturing method thereof, and a display device. By disposing a first structure in a first annular groove defined by a partition structure, the first structure and the partition structure are arranged on the same layer, and by defining that the first structure is electrically connected to a touch trace, the first structure is used as a touch structure. Thus, compared with the Oncell method in the prior art that integrates the touch function through four masks, in the embodiments of the present application, the partition structure and the first structure can be manufactured through one mask, achieving the partition effect and Incell self-capacitance touch. On the basis of ensuring the display effect and touch effect, the manufacturing cost is relatively low and the product thickness is relatively thin.
[0126] In a first aspect, referring to Figure 1 and Figure 2 , embodiments of the present application provide a display panel 10, which includes a substrate 100, a partition structure 200, a first structure 300, and a light-emitting functional layer. The substrate 100 includes a touch trace 120 and a planarization layer 130, and the planarization layer 130 covers the touch trace 120. The partition structure 200 is disposed on one side of the planarization layer 130. The partition structure 200 defines a plurality of partition openings 210 and a plurality of first annular grooves 220. A first structure 300 is disposed in the first annular groove 220. The first structure 300 is insulated from the partition structure 200, and the first structure 300 is electrically connected to the touch trace 120. The light-emitting functional layer is disposed on one side of the planarization layer 130, and the light-emitting functional layer includes a plurality of light-emitting structures 400, and the light-emitting structures 400 are disposed in the partition openings 210.
[0127] It should be noted that the substrate 100 further includes an array substrate 110, and the array substrate 110 has an array driving circuit. The touch trace 120 and the planarization layer 130 are disposed on the array substrate 110. The partition structure 200 may be in a grid shape, a plurality of annular structures, etc. The adjacent light-emitting structures 400 are separated by the partition structure 200. The plurality of light-emitting structures 400 may include a plurality of first light-emitting structures 410 that emit red light, a plurality of second light-emitting structures 420 that emit blue light, and a plurality of third light-emitting structures 430 that emit green light. The first light-emitting structures 410, the second light-emitting structures 420, and the third light-emitting structures 430 are alternately distributed. The light-emitting structure 400 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 application of a driving voltage between the anode and the cathode, so that the light-emitting structure 400 emits light, and the display panel 10 performs a display function.
[0128] The display panel 10 further includes a first encapsulation layer 500 and a second encapsulation layer 600. The first encapsulation layer 500 is used to separately encapsulate the first light-emitting structure 410, the second light-emitting structure 420, and the third light-emitting structure 430 respectively, so as to ensure that the devices of the corresponding light-emitting structures 400 are retained in the etching process. Since a cavity will be formed between the top of the first encapsulation layer 500 and the partition structure 200 after the etching process, in order to avoid the existence of a collapse phenomenon, before the subsequent preparation of the second encapsulation layer 600, a photolithography opening 510 needs to be formed in the area of the partition structure 200 on the first encapsulation layer 500. At this time, through the settings of the first encapsulation layer 500 and the second encapsulation layer 600, the encapsulation effect of the display panel 10 can be ensured, and water and oxygen erosion can be avoided.
[0129] In the display panel 10 provided by the embodiment of the present application, a first annular groove 220 is defined by the partition structure 200, a first structure body 300 is arranged in the first annular groove 220, and it is defined that the first structure body 300 is insulated from the partition structure 200 and the first structure body 300 is electrically connected to the touch trace 120. In this way, the partition structure 200 and the first structure body 300 are prepared through one mask, and the first structure body 300 is used as a touch structure. When the user touches the area where the first structure body 300 is located, through the signal transmission of the touch trace 120, Incell self-capacitance touch can be realized through the first structure body 300 without separately setting a touch layer, so that the manufacturing cost of the display panel 10 is relatively low and the product thickness is relatively thin. Moreover, since the light-emitting structure 400 is located in the partition opening 210, and the partition opening 210 and the first annular groove 220 are respectively defined by the partition structure 200, the existence of the first structure body 300 will not affect the pixel aperture ratio of the display panel 10, thereby ensuring the display effect. The international application with the application number PCT / CN2023 / 134518 and the Chinese patent applications with the application numbers 202310759370.2, 202310740412.8, 202310707209.0, and 202311346196.5 record the related technologies of the isolation structure, the content of which is incorporated into the present application by reference for reference.
[0130] It can also be understood that in the embodiment of the present application, the partition structure 200 and the first structure body 300 are integrated and prepared through one mask. The first structure body 300 for realizing touch and the partition structure 200 for realizing the partition of adjacent light-emitting structures 400 are prepared through one mask at the same time. On the one hand, the number of laminations of the display panel 10 is less and the product thickness is relatively thin. On the other hand, the area of the light-emitting structure 400 is ensured through the partition opening 210, and the pixel aperture ratio of the display panel 10 is ensured.
[0131] In one of the embodiments, continue to refer to Figure 1 and Figure 2, the flat layer 130 is provided with a plurality of first vias 131. Each first via 131 penetrates the flat layer 130, and the touch trace 120 is exposed through the first via 131. The first structure 300 is in contact with the touch trace 120 exposed by a first via 131 to achieve electrical connection between the first structure 300 and the touch trace 120.
[0132] In one example, the first structure 300 is made of a metal material. The metal material here can be a material with a small resistance, and the material of the first structure 300 can be the same as that of the touch trace 120.
[0133] In one example, the material of the first structure 300 can be one of copper, silver, gold, molybdenum, aluminum, and titanium, and the material of the first structure 300 can also be a combination of multiple of copper, silver, gold, molybdenum, aluminum, and titanium.
[0134] In this way, only an opening needs to be made on the mask for preparing the flat layer 130 to prepare the first vias 131 on the flat layer 130. The first structure 300 and the touch trace 120 are in contact through the first vias 131 on the flat layer 130, so that the electrical connection between the first structure 300 and the touch trace 120 can be more conveniently realized, which is easy to prepare and has a low cost.
[0135] It should be noted that referring to Figure 3 , the display panel 10 further includes a plurality of pixel defining parts 700. The pixel defining parts 700 are arranged on the flat layer 130, and the partition structure 200 and the first structure 300 are arranged on the pixel defining parts 700. At this time, second vias 710 are formed on the pixel defining parts 700. The second vias 710 are arranged opposite to the first vias 131 to expose the touch trace 120. The touch trace 120 exposed through the second vias 710 and the first vias 131 is in contact with the first structure 300.
[0136] In one embodiment, continue to refer to Figure 2 , a plurality of adjacent light-emitting structures 400 form a pixel unit 440, and a first structure 300 is arranged between adjacent pixel units 440. When specifically arranged, each pixel unit 440 is composed of a first light-emitting structure 410, a second light-emitting structure 420, and a third light-emitting structure 430. The first light-emitting structure 410 and the second light-emitting structure 420 are arranged in parallel along the first direction Y of the first light-emitting structure 410, and the first light-emitting structure 410 and the third light-emitting structure 430 are arranged in parallel along the second direction X of the first light-emitting structure 410. The first structure 300 can be arranged between two adjacent third light-emitting structures 430.
[0137] In one example, all pixel units 440 have the same structure, and all pixel units 440 are arranged in an array. Multiple first structures 300 are also arranged in an array, so that the structure of the light-emitting functional layer is simple and it is convenient to set up the light-emitting structure 400.
[0138] In one example, multiple first structures 300 have the same structure, which can facilitate the setting of the first structures 300 and is convenient for touch control.
[0139] In this way, by setting the first structures 300 between adjacent pixel units 440, more first structures 300 can be arranged, and the accuracy of the touch operation is limited to be the same as that of the pixel units 440, thereby improving the accuracy of the touch operation, ensuring the sensitivity of the touch operation, and enhancing the touch effect.
[0140] In one of the embodiments, the touch trace 120 has a Ti / Al / Ti laminated structure, and the metal film layers of Ti and Al can be laminated by means such as evaporation coating, inkjet printing, and coating.
[0141] In one example, the touch trace 120 defines a plurality of touch openings 121, and the touch openings 121 correspond to the pixel units 440. Each pixel unit 440 corresponds to one touch opening 121, so that the signal of the touch operation corresponds to the area of the pixel display, and the touch accuracy can be controlled at the size level of the pixel units 440, thereby improving the touch effect.
[0142] In one example, the projections of the three partition openings 210 corresponding to each pixel unit 440 on the flat layer 130 are located inside the projection of the touch opening 121 on the flat layer 130, so that the first light-emitting structure 410, the second light-emitting structure 420, and the third light-emitting structure 430 fall inside the touch opening 121, ensuring that the area where the touch trace 120 is located is directly opposite to the partition structure 200, thereby facilitating the setting of the first structures 300.
[0143] In one example, the touch trace 120 can be a mesh structure to facilitate the preparation of the touch trace 120.
[0144] In one example, the plurality of touch openings 121 are independent of each other, and each touch opening 121 is a ring structure, which can facilitate the control of the touch trace 120 and the first structures 300, and the control logic is relatively simple and easy to implement.
[0145] In this way, by defining the structure of the touch trace 120 as the laminated Ti / Al / Ti, the resistance of the touch trace 120 is reduced, and the electrical conductivity of the touch trace 120 is good, thereby reducing the touch resistance, facilitating the transmission of the touch signal, and improving the sensitivity of the touch operation.
[0146] In one embodiment, continue to refer to Figure 2 , a first structure 300 is disposed between at least two adjacent pixel units 440. When specifically disposed, one first structure 300 corresponds to two, three, four or more than four pixel units 440.
[0147] In one example, a first structure 300 is disposed between two adjacent pixel units 440, so that touch detection points are arranged between two adjacent pixel units 440, and two pixel units 440 share one touch detection point, which is convenient for touch operation.
[0148] In one example, a first structure 300 is disposed between four adjacent pixel units 440, so that touch detection points are arranged between four adjacent pixel units 440, and four pixel units 440 share one touch detection point, which is convenient for touch operation.
[0149] In this way, by disposing a first structure 300 between at least two adjacent pixel units 440, on the basis of improving touch sensitivity, the first structure 300 can be arranged in the partition structure 200 between at least two adjacent pixel units 440, so as to facilitate the setting of the first structure 300.
[0150] In one embodiment, refer to Figure 4 , Figure 5 and Figure 6 , the display panel 10 further includes a control module 900. A plurality of first annular grooves 220 are sequentially arranged around the outside of the first structure 300. A protection ring 800 is disposed in the first annular groove 220. The protection ring 800 is insulated from the first structure 300 and the partition structure 200 respectively, and the protection ring 800 is electrically connected to the control module 900. The protection ring 800 is used to protect the first structure 300 to prevent the first structure 300 from being affected by the cathode electric field of the light-emitting structure 400 during touch operation.
[0151] In one example, the height of the protection ring 800 on the flat layer 130 is not less than the height of the first structure 300 on the flat layer 130. When specifically disposed, the height of the protection ring 800 on the flat layer 130 is equal to the height of the first structure 300 on the flat layer 130, so as to reduce the thickness of the display panel 10 on the basis of ensuring the isolation between the first structure 300 and the cathode of the light-emitting structure 400. The height of the protection ring 800 on the flat layer 130 is greater than the height of the first structure 300 on the flat layer 130 to ensure the isolation effect between the first structure 300 and the cathode of the light-emitting structure 400.
[0152] In one example, the touch trace 120 is electrically connected to the control module 900 to achieve independent control of the protection ring 800 and the first structure 300 through the control module 900, and the control logic is relatively simple and easy to implement.
[0153] In this way, by providing the protection ring 800 between the partition structure 200 and the first structure 300, the light-emitting structure 400 in the partition opening 210 and the first structure 300 can be isolated, reducing the influence of the cathode electric field of the light-emitting structure 400 on the first structure 300, so that the self-capacitance between the user's finger and the first structure 300 during touch is relatively large, and it can ensure that the capacitance of the first structure 300 is vertically upward, with relatively high touch sensitivity and good touch effect.
[0154] In one of the embodiments, referring to Figure 4 、 Figure 5 and Figure 6 at least one protection ring 800 is sleeved outside the first structure 300. Specifically, one protection ring 800 is sleeved outside the first structure 300 to facilitate the preparation of the display panel 10; multiple protection rings 800 are sleeved outside the first structure 300 to further isolate the first structure 300 and the cathode of the light-emitting structure 400.
[0155] In one example, the number of the protection rings 800 is the same as that of the first structures 300, and the protection rings 800 and the first structures 300 are arranged in one-to-one correspondence, so that all the first structures 300 can be isolated from the cathode of the light-emitting structure 400.
[0156] In this way, by controlling the number of the protection rings 800, the influence of the cathode electric field of the light-emitting structure 400 on the first structure 300 can be adjusted, further reducing the influence of the cathode electric field of the light-emitting structure 400 on the first structure 300, so as to control that the self-capacitance between the user's finger and the first structure 300 during touch is relatively small and improve the touch sensitivity.
[0157] In one of the embodiments, the protection ring 800 includes a conductive material. Specifically, a part of the protection ring 800 can be a conductive material to save conductive materials; the protection ring 800 can also be directly prepared from a conductive material to facilitate the preparation of the protection ring 800.
[0158] In one example, the protection ring 800 is prepared from a metal material, and the metal material here can be a material with a relatively small resistance.
[0159] In one example, the material of the protection ring 800 can be one of copper, silver, gold, molybdenum, aluminum, and titanium, and the material of the protection ring 800 can also be a combination of multiple of copper, silver, gold, molybdenum, aluminum, and titanium.
[0160] In one example, the protection ring 800 and the first structure 300 are made of the same material. On the one hand, it is convenient to prepare the protection ring 800 and the first structure 300 simultaneously. On the other hand, it can ensure the isolation effect between the first structure 300 and the cathode of the light-emitting structure 400.
[0161] In this way, by defining that the protection ring 800 has a conductive material, only by arranging the protection ring 800 between the first structure 300 and the cathode of the light-emitting structure 400, the isolation effect between the first structure 300 and the cathode of the light-emitting structure 400 can be achieved, and the arrangement of the protection ring 800 can be facilitated.
[0162] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 4 , the partition structure 200 is integrally formed with at least one of the first structure 300 and the protection ring 800. When specifically arranged, the partition structure 200 is integrally formed with the first structure 300, and the partition structure 200 is integrally formed with the protection ring 800.
[0163] In one example, the partition structure 200 is integrally formed with the first structure 300 and the protection ring 800, so that the partition structure 200, the first structure 300, and the protection ring 800 can be formed by one mask etching.
[0164] In this way, by defining that the partition structure 200 is integrally formed with at least one of the first structure 300 and the protection ring 800, the preparation of the display panel 10 can be facilitated, the etching process can be saved, the mask cost can be saved, and the preparation cost can be reduced.
[0165] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 4 , the partition structure 200 includes an isolation portion 230 and a blocking portion 240. The isolation portion 230 is located on the side of the blocking portion 240 away from the flat layer 130. The orthographic projection of the isolation portion 230 on the flat layer 130 covers the orthographic projection of the blocking portion 240 on the flat layer 130, so that the light-emitting layers of adjacent light-emitting structures 400 are blocked by the blocking portion 240, and the cathodes of adjacent light-emitting structures 400 are blocked by the isolation portion 230.
[0166] In one example, the cross-section of the partition structure 200 is one of a T shape and an inverted trapezoid shape. The cross-section of the partition structure 200 can also be a combination of a T shape and an inverted trapezoid shape.
[0167] In this way, while improving the partition structure 200 to provide the first structure 300 that can be used as a touch structure, by defining the structural form of the partition structure 200, the partition effect of the partition structure 200 on the adjacent light-emitting structures 400 can be ensured.
[0168] In a second aspect, referring to Figure 7 , an embodiment of the present application provides a display panel 10, which includes a substrate 100, a partition structure 200, and a light-emitting functional layer. The light-emitting functional layer is disposed on one side of the substrate 100 and includes a plurality of light-emitting structures 400. The partition structure 200 is disposed on one side of the substrate 100. The partition structure 200 defines a plurality of partition openings 210 and a plurality of first annular grooves 220. A first structure 300 is disposed in the first annular groove 220. The first structure 300 is used to connect touch signals and is insulated from the partition structure 200. Adjacent light-emitting structures 400 are partitioned by the partition structure 200. The light-emitting structures 400 are disposed in the partition openings 210 and are arranged in one-to-one correspondence with the partition openings 210.
[0169] It should be noted that the substrate 100 includes an array substrate. The array substrate has an array driving circuit electrically connected to the anode. The array driving circuit is used to control the application of a driving voltage between the anode and the cathode of the light-emitting structure 400, and the light-emitting structure 400 emits light, and the display panel 10 performs a display function. The partition structure 200, the first structure 300, the light-emitting structure 400, the first encapsulation layer 500, and the second encapsulation layer 600 in the display panel 10 are the same as those in the first aspect and will not be described in detail herein.
[0170] In the display panel 10 provided by the embodiment of the present application, the first annular groove 220 is defined by the partition structure 200, the first structure 300 is disposed in the first annular groove 220, and it is defined that the first structure 300 is insulated from the partition structure 200 and the first structure 300 is used to connect touch signals, so that the partition structure 200 and the first structure 300 can be prepared by one mask, and the first structure 300 is used as a touch structure. The user touches the area where the first structure 300 is located, and the touch signal is transmitted through the first structure 300. Without separately providing a touch layer, Incell self-capacitance touch can be realized through the first structure 300, so that the manufacturing cost of the display panel 10 is relatively low and the product thickness is relatively thin. Moreover, since the light-emitting structure 400 is located in the partition opening 210, and the partition opening 210 and the first annular groove 220 are respectively defined by the partition structure 200, the presence of the first structure 300 does not affect the pixel aperture ratio of the display panel 10, thereby ensuring the display effect.
[0171] It can also be understood that: in the embodiment of the present application, the partition structure 200 and the first structure 300 are integrally prepared on the same layer of a mask. The first structure 300 is used to implement touch operations by connecting touch signals. The partition structure 200 forms a partition opening 210 to isolate adjacent light-emitting structures 400. On the one hand, this makes the stack of the display panel 10 with touch function less and the product thickness thinner. On the other hand, the area of the light-emitting structure 400 is ensured through the partition opening 210, and the pixel aperture ratio of the display panel 10 is ensured.
[0172] In one embodiment, refer to Figure 8 , three adjacent light-emitting structures 400 form a pixel unit 440, and the first structure 300 is arranged between adjacent pixel units 440. When specifically arranged, in the pixel unit 440, the first light-emitting structure 410 and the second light-emitting structure 420 are arranged in parallel along the first direction Y of the first light-emitting structure 410, the first light-emitting structure 410 and the third light-emitting structure 430 are arranged in parallel along the second direction X of the first light-emitting structure 410, and the first structure 300 can be arranged between two adjacent third light-emitting structures 430.
[0173] In one example, a first structure 300 is arranged between two adjacent pixel units 440. A touch detection point is formed between two adjacent pixel units 440 through one first structure 300, and two adjacent pixel units 440 share one touch detection point, which is convenient for touch operations.
[0174] In one example, a first structure 300 is arranged between four adjacent pixel units 440. A touch detection point is formed between four adjacent pixel units 440 through one first structure 300, and four adjacent pixel units 440 share one touch detection point, which is convenient for touch operations.
[0175] In this way, by defining that the first structure 300 is arranged between adjacent pixel units 440, more first structures 300 can be conveniently arranged. Moreover, after such an arrangement, the accuracy of the touch operation is consistent with the accuracy of the pixel unit 440. By adjusting the setting methods of the pixel unit 440 and the first structure 300, the sensitivity of the touch operation can be ensured and the touch effect can be improved.
[0176] In one embodiment, refer to Figure 8 , a plurality of first annular grooves 220 are sequentially arranged around the outside of the first structure 300. A protection ring 800 is arranged in the first annular groove 220. The protection ring 800 is used to connect a protection signal. The protection ring 800 is sleeved outside the first structure 300. The protection ring 800 is insulated from the first structure 300 and the partition structure 200. The protection ring 800 is used to isolate the cathode electric field of the light-emitting structure 400 and the first structure 300.
[0177] In one example, the height of the guard ring 800 on the flat layer 130 is not less than the height of the first structure 300 on the flat layer 130 to ensure the isolation effect between the first structure 300 and the cathode of the light-emitting structure 400.
[0178] In this way, the guard ring 800 isolates the partition structure 200 and the first structure 300, so that the cathode electric field of the light-emitting structure 400 in the partition opening 210 and the capacitance of the first structure 300 can be isolated by the guard ring 800, reducing the influence of the cathode electric field of the light-emitting structure 400 on the first structure 300, making the self-capacitance between the user's finger and the first structure 300 larger during touch, and ensuring that the capacitance of the first structure 300 is vertically upward, with higher touch sensitivity and better touch effect.
[0179] In a third aspect, referring to Figure 9 , the application embodiment provides a display panel 10, which includes a substrate 100, a partition functional layer, and a light-emitting functional layer. The partition functional layer is disposed on one side of the substrate 100. The partition functional layer has a plurality of first annular grooves 220, and the partition functional layer includes a partition structure 200 and a first structure 300. The partition structure 200 and the first structure 300 are located on both sides of the first annular groove 220. The partition structure 200 defines a plurality of partition openings 210. The first structure 300 is located in the first annular groove 220, and the first structure 300 is used to connect a touch signal. The first structure 300 and the partition structure 200 are insulated from each other. The light-emitting functional layer is disposed on one side of the substrate 100. The light-emitting functional layer includes a plurality of light-emitting structures 400. The light-emitting structures 400 are disposed in the partition openings 210, and the light-emitting structures 400 are arranged in one-to-one correspondence with the partition openings 210.
[0180] It should be noted that the substrate 100 includes an array substrate. The array substrate has an array driving circuit, which is electrically connected to the anode. The array driving circuit is used to control the application of a driving voltage between the anode and the cathode of the light-emitting structure 400, and the light-emitting structure 400 emits light, and the display panel 10 performs a display function. The partition structure 200, the first structure 300, the light-emitting structure 400, the first encapsulation layer 500, and the second encapsulation layer 600 in the display panel 10 are the same as those in the first aspect and will not be described in detail here.
[0181] The display panel 10 provided by the embodiment of the present application divides the partition function layer into a partition structure 200 and a second structure body through the first annular groove 220. The partition structure 200 defines a plurality of partition openings 210. A first structure body 300 is arranged in the first annular groove 220, and it is defined that the first structure body 300 is insulated from the partition structure 200 and the first structure body 300 is used to connect a touch signal, so as to prepare the partition structure 200 and the first structure body 300 through one mask, and use the first structure body 300 as a touch structure. The user touches the area where the first structure body 300 is located and transmits the touch signal through the first structure body 300, and the Incell self-capacitance touch can be realized through the first structure body 300 without separately setting a touch layer, so that the manufacturing cost of the display panel 10 is relatively low and the product thickness is relatively thin. Moreover, since the light-emitting structure 400 is located in the partition opening 210, the existence of the first structure body 300 will not affect the pixel aperture ratio of the display panel 10, thereby ensuring the display effect.
[0182] It can also be understood that: the embodiment of the present application prepares the partition function layer through one mask. The partition function layer is divided into a partition structure 200 and a first structure body 300 through the first annular groove 220. The first structure body 300 is used to connect a touch signal to realize a touch operation. The partition structure 200 forms a partition opening 210 to isolate adjacent light-emitting structures 400. On the one hand, the number of stacked layers of the display panel 10 with a touch function is less and the product thickness is relatively thin. On the other hand, the area of the light-emitting structure 400 is ensured through the partition opening 210, and the pixel aperture ratio of the display panel 10 is ensured.
[0183] In one embodiment, referring to Figure 9 , the partition structure 200 and the first structure body 300 are arranged on the same layer.
[0184] In an example, the partition structure 200 and the first structure body 300 are integrally formed, so that the partition structure 200 and the first structure body 300 can be etched through one mask.
[0185] In this way, by defining that the partition structure 200 and the first structure body 300 are arranged on the same layer, the film layer thickness of the partition function layer is made consistent as a whole, the thickness of the partition function layer is relatively small, and the thickness of the display panel 10 is ensured to be relatively thin, thereby facilitating the preparation of the partition function layer.
[0186] Fourth aspect, referring to Figure 10, an application embodiment provides a display panel 10, which includes a substrate 100, a partition structure 200, and a light-emitting functional layer. The partition structure 200 is disposed on one side of the substrate 100. The partition structure 200 defines a plurality of partition openings 210 and a plurality of first annular grooves 220. A first structure 300 and a protection ring 800 are disposed in the first annular groove 220. The first structure 300 is used for connecting a touch signal, and the protection ring 800 is used for connecting a protection signal. The protection ring 800 is sleeved outside the first structure 300, and the protection ring 800 is spaced apart from the first structure 300. The protection ring 800 is insulated from the first structure 300 and the partition structure 200. The light-emitting functional layer is disposed on one side of the substrate 100. The light-emitting functional layer includes a plurality of light-emitting structures 400. Adjacent light-emitting structures 400 are partitioned by the partition structure 200. The light-emitting structures 400 are disposed in the partition openings 210, and the light-emitting structures 400 are arranged in one-to-one correspondence with the partition openings 210.
[0187] It should be noted that the substrate 100 includes an array substrate, and the array substrate has an array driving circuit electrically connected to an anode. The array driving circuit is used for controlling a driving voltage applied between an anode and a cathode of the light-emitting structure 400, and the light-emitting structure 400 emits light, and the display panel 10 performs a display function. The partition structure 200, the first structure 300, the light-emitting structure 400, the first encapsulation layer 500, and the second encapsulation layer 600 in the display panel 10 are the same as those in the first aspect, and will not be described in detail herein.
[0188] In the display panel 10 provided by the application embodiment, the partition structure 200 defines the first annular groove 220, the first structure 300 and the protection ring 800 are disposed in the first annular groove 220, and it is defined that the first structure 300 is insulated from the partition structure 200 and the protection ring 800. The first structure 300 is used for connecting a touch signal, and the protection ring 800 is used for connecting a protection signal, so as to fabricate the partition structure 200, the first structure 300, and the protection ring 800 through a single mask, and the first structure 300 is used as a touch structure, and the protection ring 800 is used as a protection structure. A user touches the area where the first structure 300 is located, and the touch signal is transmitted through the first structure 300. Incell self-capacitance touch can be realized through the first structure 300 without separately setting a touch layer, so that the manufacturing cost of the display panel 10 is relatively low and the product thickness is relatively thin. Moreover, since the light-emitting structure 400 is located in the partition opening 210, and the partition opening 210 and the first annular groove 220 are respectively defined by the partition structure 200, the existence of the first structure 300 will not affect the pixel aperture ratio of the display panel 10, thereby ensuring the display effect. Moreover, the influence of the cathode electric field of the light-emitting structure 400 on the first structure 300 is reduced through the protection ring 800, and the touch sensitivity is improved.
[0189] It can also be understood that in the embodiments of the present application, the partition structure 200, the first structure 300, and the protection ring 800 are integrated and prepared on the same layer of a mask. The first structure 300 is used to implement a touch operation by connecting a touch signal.

The protection ring 800 is used to implement an isolation protection function through a protection signal. On the one hand, it makes the display panel 10 with touch function have fewer layers and a thinner product thickness. On the other hand, the area of the light-emitting structure 400 is ensured through the partition opening 210, and the pixel aperture ratio of the display panel 10 is ensured.

The signal input path is short, and it is more convenient to implement signal input to the first structure 300 and the protection ring 800.
[0193] In one embodiment, the partition structure 200, the first structure 300, and the protection ring 800 respectively include a conductive material. When specifically arranged, a part of the partition structure 200, the first structure 300, and the protection ring 800 can be a conductive material, or all can be conductive materials.
[0194] In an example, the conductive material is a metal material, and the metal material here can be a material with a small resistance.
[0195] In an example, the material of the conductive material can be one of copper, silver, gold, molybdenum, aluminum, and titanium, and the material of the conductive material can also be a combination of multiple of copper, silver, gold, molybdenum, aluminum, and titanium.
[0196] In an example, the partition structure 200, the first structure 300, and the protection ring 800 have the same material, so as to facilitate the simultaneous and same-layer preparation of the materials of the partition structure 200, the first structure 300, and the protection ring 800.
[0197] In this way, by defining that the partition structure 200, the first structure 300, and the protection ring 800 respectively include a conductive material, so that the partition structure 200, the first structure 300, and the protection ring 800 are all conductive structures, which can facilitate the input of the cathode signal, touch signal, and protection signal of the light-emitting structure 400.
