[0059] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0061] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region. Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.

[0062] A light-emitting functional layer, a driving circuit layer and a touch layer are arranged in the display panel. The driving circuit layer is used to drive the light-emitting functional layer to emit light and display, and the touch layer is used to enable the user to touch the display panel. The touch layer and the driving circuit layer are arranged on opposite sides of the light-emitting functional layer. Parasitic capacitance is generated between the touch layer and the driving circuit, which causes radio frequency interference between them and reduces the image quality displayed by the display panel.

[0063] In order to solve the above problems, embodiments of the present application provide a display panel and a display device. Various embodiments of the display panel and the display device will be described below in conjunction with the accompanying drawings.

[0064] In a first aspect, the present application provides a display panel 100, such as Figure 1 and Figure 2 As shown, the display panel 100 includes a substrate 1, an isolation structure 2, a light-emitting functional layer 3, a touch layer 4 and a light-transmitting shielding layer 5. The isolation structure 2 is arranged on one side of the substrate 1, and the isolation structure 2 surrounds a plurality of defined openings 23 and a plurality of light-transmitting openings 24; the light-emitting functional layer 3 includes a plurality of light-emitting portions 31, and the light-emitting portions 31 are at least partially arranged in the defined openings 23; the touch layer 4 is arranged on the side of the isolation structure 2 away from the substrate 1; the light-transmitting shielding layer 5 is arranged between the isolation structure 2 and the touch layer 4, and along the direction from the touch layer 4 to the substrate 1, the light-transmitting shielding layer 5 blocks at least a portion of the light-transmitting openings 24.

[0065] The display panel 100 provided in the embodiment of the present application may be an organic light emitting diode (OLED) display panel 100 .

[0066] In the display panel 100 provided in the embodiment of the present application, the substrate 1 can not only provide support for the isolation structure 2, but also provide electrical signals for the light-emitting functional layer 3 and the touch layer 4. There are many ways to set the substrate 1. In some embodiments, the substrate 1 may include a substrate 11 and a driving circuit layer 12 arranged on the substrate 11, and the driving circuit layer 12 may include a pixel driving circuit, a plurality of conductive connection structures stacked and arranged, and the like. Exemplarily, the pixel driving circuit arranged in the driving circuit layer 12 includes a transistor and a storage capacitor. The transistor includes an active layer 121, a gate 122, a drain 123 and a source 124. The storage capacitor includes a first plate 125 and a second plate 126. As an example, the gate 122 and the first plate 125 may be located in the same conductive layer 211, the second plate 126 may be located in another conductive layer, and the drain 123 and the source 124 may be located in another conductive layer.

[0067] Please refer to Figure 3The isolation structure 2 is surrounded by a plurality of defined openings 23 and a plurality of light-transmitting openings 24, and adjacent defined openings 23 and light-transmitting openings 24 are spaced apart by the isolation structure 2. The number of defined openings 23 may correspond to the number of light-emitting portions 31. Light entering the display panel 100 from one side of the display panel 100 may pass through the light-transmitting openings 24 and be emitted from the other side of the display panel 100, and a light sensor located on one side of the display panel 100 receives the light to realize photoelectric conversion. The light sensor may specifically be an infrared sensor, a camera, etc.

[0068] The plurality of light emitting parts 31 may be light emitting parts 31 capable of emitting light of different colors. For example, they may be a red light emitting part 311 capable of emitting red light, a green light emitting part 312 capable of emitting green light, and a blue light emitting part 313 capable of emitting blue light. The number of the limited openings 23 and the light-transmitting openings 24 may be determined as required, for example Figure 3 In the illustrated embodiment, the red light emitting unit 311, the green light emitting unit 312, and the blue light emitting unit 313 are respectively located in the three defined openings 23 and form a pixel light emitting group, and one pixel light emitting group corresponds to one light-transmitting opening 24 to form a repeating unit, and the repeating units are arranged in an array along the second direction Y and the third direction Z. In another embodiment, a plurality of pixel light emitting groups correspond to one light-transmitting opening 24 to form a repeating unit, and the repeating units are arranged in an array along the second direction Y and the third direction Z.

[0069] The touch layer 4 enables the display device to perform touch operation. The touch layer 4 can be arranged on the light-emitting side of the light-emitting functional layer 3. In order to prevent the touch layer 4 from affecting the display of the light-emitting functional layer 3, the touch layer 4 can be made of a light-transmitting material. The touch layer 4 can include touch electrodes arranged at intervals, and adjacent touch electrodes cooperate to form a touch capacitor. The touch position of the display panel 100 by the user can be determined by analyzing the electrical signal of the change of the touch capacitor.

[0070] The light-transmitting shielding layer 5 can be made of a light-transmitting conductive material, such as indium oxide-tin oxide (ITO), indium oxide-zinc oxide (IZO), etc. The light emitted by the light-emitting portion 31 can pass through the light-transmitting shielding layer 5, and the light incident on the display panel 100 can pass through the light-transmitting shielding layer 5. Since the light-transmitting shielding layer 5 blocks at least part of the light-transmitting opening 24, the radio frequency between the touch layer 4 and the driving circuit layer 12 that can pass through the light-transmitting opening 24 can be shielded by the light-transmitting shielding layer 5. Optionally, the light-transmitting shielding layer 5 blocks the light-transmitting opening 24 to improve the ability of the light-transmitting shielding layer 5 to shield the radio frequency between the touch layer 4 and the driving circuit layer 12 that can pass through the light-transmitting opening 24.

[0071] The display panel 100 provided in the present application may further include a cover plate covering the side of the touch layer 4 facing away from the substrate 1 , an optical adhesive layer 75 located between the cover plate and the touch layer 4 , a touch encapsulation layer 74 encapsulating the touch layer 4 , and the like.

[0072] In the embodiment provided in the present application, a light-transmitting opening 24 is provided, so that the light transmittance of the display panel 100 can be improved; by providing a light-transmitting shielding layer 5 between the isolation structure 2 and the touch layer 4, the light-transmitting shielding layer 5 is provided to block at least a portion of the light-transmitting opening 24, so that the radio frequency between the touch layer 4 and the driving circuit layer 12 that can pass through the light-transmitting opening 24 can be shielded by the light-transmitting shielding layer 5, thereby avoiding or reducing the radio frequency interference between the touch layer 4 and the driving circuit layer 12, and improving the image quality displayed by the display panel 100.

[0073] In some embodiments, the display panel 100 further includes a first planar layer 6 , which covers a side of the isolation structure 2 facing away from the substrate 1 , and the first planar layer 6 covers a side of the light-emitting functional layer 3 facing away from the substrate 1 .

[0074] Since the surface of the isolation structure 2 facing away from the substrate 1 and the surface of the light-emitting functional layer 3 facing away from the substrate 1 are uneven, by setting a side of the isolation structure 2 facing away from the substrate 1 and a side of the light-emitting functional layer 3 facing away from the substrate 1, the end of the first flat layer 6 facing away from the substrate 1 has a flat surface, which facilitates the arrangement of other functional layers on the first flat layer 6. The first flat layer 6 can be an organic film layer.

[0075] In some embodiments, the light-transmitting shielding layer 5 is disposed on a side of the first planar layer 6 facing away from the substrate 1 .

[0076] Compared with directly setting the light-transmitting shielding layer 5 on the isolation structure 2 and the light-emitting functional layer 3, the first flat layer 6 has a flat surface on the side facing away from the substrate 1, which can avoid or reduce the breakage of the prepared light-transmitting shielding layer 5, making the light-transmitting shielding layer 5 complete and reliable.

[0077] In some embodiments, the display panel 100 further includes a first encapsulation layer 71 , which is disposed between the first planar layer 6 and the touch layer 4 , and covers a side of the light-transmitting shielding layer 5 that is away from the substrate 1 .

[0078] The first encapsulation layer 71 may include organic materials and / or inorganic materials. The first encapsulation layer 71 may improve the barrier capability of the display panel 100 against water and oxygen, thereby preventing external water and oxygen from entering the light-emitting functional layer 3 and affecting the light emission of the light-emitting portion 31 .

[0079] In some embodiments, the display panel 100 further includes a second encapsulation layer 72 , and the second encapsulation layer 72 is disposed between the first encapsulation layer 71 and the touch layer 4 .

[0080] The second encapsulation layer 72 may include organic materials and / or inorganic materials. The first encapsulation layer 71 and the second encapsulation layer 72 may be made of different materials so that the first encapsulation layer 71 and the second encapsulation layer 72 may have different properties to improve the ability of the display panel 100 to resist water and oxygen.

[0081] In some embodiments, the first encapsulation layer 71 is an organic material layer, and the second encapsulation layer 72 is an inorganic material layer.

[0082] Compared with the organic material layer, the inorganic material layer has a better ability to block water and oxygen. Compared with the inorganic material layer, the organic material layer has better flexibility and good film-forming properties. The light-emitting functional layer 3 is encapsulated by the organic material layer and the inorganic material layer together to improve the comprehensive ability of the display panel 100 to resist water and oxygen.

[0083] In some embodiments, the thickness of the first encapsulation layer 71 along the thickness direction of the display panel 100 is H1, the thickness of the second encapsulation layer 72 along the thickness direction of the display panel 100 is H2, and H1>H2.

[0084] The first flat layer 6, the first encapsulation layer 71 and the second encapsulation layer 72 can all provide a flat surface to form the light-transmitting shielding layer 5, but because H1>H2, the light-transmitting shielding layer 5 is arranged on the side of the first encapsulation layer 71 close to the substrate 1, so that the first encapsulation layer 71 and the second encapsulation layer 72 are spaced between the light-transmitting shielding layer 5 and the touch layer 4, thereby increasing the spacing distance between the light-transmitting shielding layer 5 and the touch layer 4, and avoiding or reducing the light-transmitting shielding layer 5 from affecting the functional realization of the touch layer 4 to a certain extent.

[0085] In some embodiments, the display panel further includes a third encapsulation layer 76 , which is disposed between the first planar layer 6 and the light-emitting functional layer 3 , and covers the light-emitting portion 31 .

[0086] The light-emitting functional layer 3 may further include a first electrode 32 and a second electrode 33 disposed on opposite sides of the light-emitting portion 31. The first electrode 32, the light-emitting portion 31, and the second electrode 33 are stacked in a direction from the touch layer 4 to the substrate 1. One of the first electrode 32 and the second electrode 33 may be a cathode, and the other may be an anode. The first electrode 32 and the second electrode 33 are respectively connected to the light-emitting portion 31 and are used to drive the light-emitting portion 31 to emit light. The third encapsulation layer 76 may cover the side of the first electrode 32 away from the substrate 1. The third encapsulation layer 76 may reduce or prevent water and oxygen from entering the light-emitting portion 31, thereby increasing the service life of the light-emitting portion 31.

[0087] The material of the third encapsulation layer 76 may be the same as the material of the first encapsulation layer 71 or the material of the second encapsulation layer 72 to simplify the manufacturing process.

[0088] In some embodiments, the third encapsulation layer 76 includes a plurality of encapsulation portions 761 , at least a portion of the encapsulation portion 761 is located within the defined opening 23 and covers the light emitting portion 31 , and an edge of the encapsulation portion 761 overlaps the isolation structure 2 .

[0089] The encapsulation part 761 and the light emitting part 31 can be arranged in a one-to-one correspondence, that is, one encapsulation part 761 is used to encapsulate one light emitting part 31. The encapsulation part 761 can be arranged entirely within the defined opening 23, or can be partially extended to the outside of the defined opening 23. The edge of the encapsulation part 761 overlaps with the isolation structure 2 to avoid or reduce the formation of a gap between the encapsulation part 761 and the isolation structure 2 through which water and oxygen can pass.

[0090] Since the light emitting portion 31 is not disposed in the light-transmitting opening 24 , the third encapsulation layer 76 may not be disposed in the light-transmitting opening 24 , so as to reduce or avoid unnecessary refraction of light incident into the light-transmitting opening 24 in the light-transmitting opening 24 , thereby improving the light transmittance of the light-transmitting opening 24 .

[0091] See also Figure 4 In some embodiments, the touch layer 4 is electrically connected to the light-transmitting shielding layer 5 .

[0092] By setting the touch layer 4 and the light-transmitting shielding layer 5 to be electrically connected, the touch layer 4 and the light-transmitting shielding layer 5 can maintain close or consistent potentials, thereby avoiding or reducing the parasitic capacitance between the touch layer 4 and the light-transmitting shielding layer 5 to a certain extent.

[0093] In some embodiments, the first encapsulation layer 71 includes a first opening 711 , the light-transmitting shielding layer 5 is exposed from the first opening 711 , and a portion of the touch layer 4 is disposed in the first opening 711 and electrically connected to the light-transmitting shielding layer 5 .

[0094] Part of the touch layer 4 is formed in the first opening 711 and is electrically connected to the light-transmitting shielding layer 5, so that the touch layer 4 and the light-transmitting shielding layer 5 can be electrically connected. The aforementioned part of the touch layer 4 can specifically be the ground terminal (TSP GND) of the touch layer 4. The display panel 100 includes a display area AA and a non-display area NA that are connected, and the first opening 711 is located in the non-display area NA. By setting the first opening 711 in the non-display area, the connection between the light-transmitting shielding layer 5 and the touch layer 4 is located in the non-display area. In the case where other layer structures are provided between the touch layer 4 and the light-transmitting shielding layer 5, a through hole penetrating the layer structure is provided to achieve a through-hole connection between the touch layer 4 and the light-transmitting shielding layer 5. As Figure 4In the illustrated embodiment, the display panel 100 further includes a second encapsulation layer 72 and a touch buffer layer 73. The light-transmitting shielding layer 5, the first encapsulation layer 71, the second encapsulation layer 72, the touch buffer layer 73 and the touch layer 4 are stacked in sequence along the first direction X. A through hole is provided that penetrates the first encapsulation layer 71, the second encapsulation layer 72 and the touch buffer layer 73. The first opening 711 may be a section of the through hole, and the touch layer 4 and the light-transmitting shielding layer 5 are connected via the through hole.

[0095] See also Figure 5 In some embodiments, the light-transmitting shielding layer 5 further includes a plurality of first through holes 51 , and the first planarizing layer 6 and the first encapsulation layer 71 are in contact with each other through the first through holes 51 .

[0096] The first planar layer 6 and the first encapsulation layer 71 are in contact through the first through hole 51, so that the first through hole 51 can be used as a vent hole. When the display panel 100 is in a high temperature environment, the gas released by some materials in the display panel 100 can be discharged through the vent hole to avoid bubbling of the film layer. Some materials in the display panel 100 can be organic materials of the first planar layer 6. When the first planar layer 6 is in a high temperature environment, the gas released by the organic materials in the first planar layer 6 can be discharged through the vent hole to the first encapsulation layer 71, and then discharged to the outside through the first encapsulation layer 71 to avoid bubbling of the first planar layer 6.

[0097] See also Figure 6 The first through holes 51 may be regularly distributed or randomly distributed, and the shape and size of the first through holes 51 may be determined as required. For example: Figure 6 The first through hole 51a shown is a through hole with a circular cross section, and a plurality of first through holes 51a are randomly distributed. For another example: Figure 7 The first through hole 51b shown is a through hole with a rectangular cross section, and a plurality of first through holes 51b correspond to a plurality of pixel light-emitting groups one by one to form a repeating unit, and the light-transmitting shielding layer 5 covers the pixel light-emitting groups. For another example: Figure 7 The first through hole 51 c shown is a through hole with a rectangular cross section. A plurality of first through holes 51 b correspond one-to-one with a plurality of pixel light-emitting groups to form a repeating unit, and the light-emitting portion 31 is exposed from the first through hole 51 .

[0098] Please refer to Figure 5 and Figure 7 In some embodiments, the orthographic projection of the light emitting portion 31 on the light-transmitting shielding layer 5 at least partially overlaps with the first through hole 51, so that part of the light emitted by the light emitting portion 31 can be directly emitted outward through the first through hole 51 without passing through the light-transmitting shielding layer 5. Optionally, the orthographic projection of the light emitting portion 31 on the light-transmitting shielding layer 5 falls within the first through hole 51.

[0099] See also Figure 8In some embodiments, the light-emitting functional layer 3 is electrically connected to the light-transmitting shielding layer 5 .

[0100] By setting the light-emitting functional layer 3 to be electrically connected with the light-transmitting shielding layer, the light-emitting functional layer 3 and the light-transmitting shielding layer 5 can maintain close or consistent potentials, thereby avoiding or reducing the parasitic capacitance between the light-emitting functional layer 3 and the light-transmitting shielding layer 5 to a certain extent.

[0101] In some embodiments, the isolation structure 2 includes a conductive layer 211 , and the light-emitting functional layer 3 includes a first electrode 32 . The first electrode 32 is connected to the light-emitting portion 31 on a side close to the substrate 1 , and an edge of the first electrode 32 overlaps the conductive layer 211 .

[0102] The first electrode 32 may be a cathode or an anode, and the first electrode 32 is connected to the light emitting portion 31 to drive the light emitting portion 31 to emit light. The edge of the first electrode 32 overlaps the conductive layer 211, so that the conductive layer 211 can supply power to the first electrode 32, and can also realize the conduction of the adjacent first electrodes 32, thereby forming a surface electrode with a conductive surface.

[0103] When the first electrode 32 and the conductive layer 211 are overlapped to form a surface electrode, the touch layer 4 and the driving circuit layer 12 can be shielded by the surface electrode, and the portion between the touch layer 4 and the driving circuit layer 12 that is not shielded by the surface electrode at the light-transmitting opening 24 can be shielded by the light-transmitting shielding layer 5.

[0104] In some embodiments, the first planar layer 6 includes a second opening 61 , the conductive layer 211 is exposed from the second opening 61 , and a portion of the light-transmitting shielding layer 5 is disposed in the second opening 61 and electrically connected to the conductive layer 211 .

[0105] Part of the light-transmitting shielding layer 5 is formed in the second opening 61 and is electrically connected to the conductive layer 211, so that the conductive layer 211 and the light-transmitting shielding layer 5 can be electrically connected. The conductive layer 211 exposed from the second opening 61 can be a power supply voltage terminal (ELVSS) or a common ground voltage terminal (ELVDD) electrically connected to the light-emitting functional layer 3.

[0106] In some embodiments, the display panel 100 includes a display area AA and a non-display area NA that are connected to each other, the conductive layer 211 includes a main body located in the display area AA and a frame portion located in the non-display area NA, the second opening 61 is located in the non-display area NA, the light-transmitting shielding layer 5 is spaced apart from the main body, and the light-transmitting shielding layer 5 is connected to the frame portion exposed in the second opening 61.

[0107] The light emitting portion 31 may be disposed only in the display area AA. The portion of the light-transmitting shielding layer 5 located in the display area AA is spaced apart from the main body, and the portion located in the non-display area NA may be electrically connected to the frame portion through the second opening 61. By disposing the second opening 61 in the non-display area NA and connecting the light-transmitting shielding layer 5 to the frame portion exposed in the second opening 61, the connection between the light-transmitting shielding layer 5 and the conductive layer 211 is located in the non-display area NA.

[0108] In some embodiments, the display panel 100 further includes a plurality of second electrodes 33, which are located on a side of the light-emitting portion 31 close to the substrate 1. One of the first electrode 32 and the second electrode 33 can be used as an anode electrode, and the other can be used as a cathode electrode. The first electrode 32, the light-emitting portion 31, and the second electrode 33 can be stacked and contacted in sequence to achieve electrical conduction between the first electrode 32, the light-emitting portion 31, and the second electrode 33. Optionally, the first electrode 32 is an anode electrode, and the second electrode 33 is a cathode electrode.

[0109] Please refer to Figure 3 , Figure 5 and Fig. 9 In some embodiments, the light-transmitting opening 24 is located between adjacent limiting openings 23 .

[0110] A plurality of light-transmitting openings 24 may be evenly distributed in the isolation structure 2, or may be concentrated and distributed in a partial area of ​​the isolation structure 2. In some embodiments, the display panel 100 has a display area AA, and at least a portion of the display area AA is reused as a light sensing area SA, that is, the light sensing area SA is located in the display area AA, and at least a portion of the display area AA is used for both picture display and light sensing. The light-transmitting openings 24 are arranged in the light sensing area SA to improve the light transmittance of the light sensing area SA, so that one side of the light sensing area SA is suitable for placing a light sensor. Light incident on the display panel 100 from one side of the display panel 100 can be emitted from the other side of the display panel 100 through the light-transmitting openings 24, and the light sensor located on one side of the display panel 100 receives the light to realize photoelectric conversion. The light sensor may specifically be an infrared sensor, a camera, etc.

[0111] Optionally, the isolation structure 2 is in a grid shape, the defining openings 23 are arranged in an array, and the light-transmitting openings 24 are disposed between adjacent defining openings 23 .

[0112] In some embodiments, along the direction from the touch layer 4 to the substrate 1 , the light-transmitting shielding layer 5 shields at least a portion of the isolation structure 2 .

[0113] The light-transmitting shielding layer 5 not only blocks the light-transmitting opening 24 , but also blocks at least a portion of the isolation structure 2 , so as to increase the shielding area of ​​the light-transmitting shielding layer 5 between the touch layer 3 and the substrate 1 that can realize the shielding function.

[0114] In some embodiments, the isolation structure 2 includes a first portion 21 and a second portion 22 which are stacked, wherein the first portion 21 is disposed on a side of the second portion 22 close to the substrate 1 , and the orthographic projection of the first portion 21 on the substrate 1 is located within the orthographic projection of the second portion 22 on the substrate 1 .

[0115] The isolation structure 2 encloses and forms a limited opening 23 to limit the setting range of the light-emitting functional layer 3. The isolation structure 2 includes a first portion 21 and a second portion 22 which are stacked, and the orthographic projection of the first portion 21 on the substrate 1 is located within the orthographic projection of the second portion 22 on the substrate 1, so that the cross-sectional area of ​​the end of the isolation structure 2 away from the substrate 1 is larger, and the cross-sectional area of ​​the end of the isolation structure 2 close to the substrate 1 is smaller. Along the direction from the isolation structure 2 to the substrate 1 (X direction), the second portion 22 completely blocks the first portion 21.

[0116] When preparing the light-emitting portion 31, the light-emitting material A used to prepare the light-emitting portion 31 can be covered on the isolation structure 2 based on the evaporation technology. Since the second part 22 blocks the first part 21, the light-emitting material A used to prepare the light-emitting portion 31 has a large drop at the edge of the second part 22, and the light-emitting material A falling in the defined opening 23 and the light-emitting material A falling on the second part 22 are difficult to connect, so they are broken, forming light-emitting materials A arranged in adjacent defined openings 23 at intervals. The light-emitting material A falling on the second part 22 can be removed as needed. Compared with the preparation of the light-emitting functional layer 3 by mask evaporation in the related art, the present application sets the first part 21 and the second part 22, so that the light-emitting portion 31 located in the defined opening 23 can be prepared without a metal mask, thereby saving the cost of preparing the metal mask. Compared with preparing the light-emitting functional layer 3 by preparing a high-precision metal mask for evaporation, it is easier to directly prepare the isolation structure 2 with high precision, so that the structure of the display panel 100 provided by the present application has low requirements on the preparation process, and the consistency of the prepared display panel 100 is good. The luminescent material A may be a complex containing indium element.

[0117] In some embodiments, the orthographic projection area of ​​the surface of the second portion 22 facing away from the substrate 1 on the substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the substrate 1 on the substrate 1 .

[0118] The second portion 22 extends outwardly by a predetermined distance relative to the first portion 21, that is, the orthographic projection area of ​​the surface of the second portion 22 facing away from the substrate 1 on the substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the substrate 1 on the substrate 1, so that the second portion 22 has an inclined slope structure, so that the pattern of the light-emitting functional layer 3 can be defined by the second portion 22.

[0119] In some embodiments, the cross-sectional area of ​​the second portion 22 gradually decreases in a direction away from the substrate 1 .

[0120] Optionally, the cross-section of the second portion 22 is a trapezoid with the bottom edge facing the substrate 1, so that the second portion 22 has a sloped surface, which is conducive to the preparation material being disconnected at the partition edge, forming a state in which part of the preparation material is located on the second portion 22 and part of the preparation material is located in the limited opening 23.

[0121] In some embodiments, the orthographic projection area of ​​the surface of the first portion 21 facing away from the substrate 1 on the substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the substrate 1 on the substrate 1 .

[0122] That is, the second portion 22 extends outward relative to the first portion 21, so as to limit the pattern of the first electrode 32 and the light-emitting functional layer 3 through the second portion 22. The area of ​​the second portion 22 is larger than that of the first portion 21, and the first portion 21 is completely covered, and at this time, the first portion 21 is recessed relative to the second portion 22 in a direction away from the defined opening 23. When preparing the second electrode 33, the second electrode 33 has a large drop at the edge of the isolation structure 2, and the first portion 21 is recessed, so that the second electrode 33 is difficult to connect outside the isolation structure 2, and thus a break is found, forming mutually isolated second electrodes 33.

[0123] In some embodiments, the orthographic projection area of ​​the surface of the second portion 22 facing away from the substrate 1 on the substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the substrate 1 on the substrate 1 .

[0124] The conductive layer 211 in the isolation structure 2 can be located in the first subsection 21 or in the second subsection 22, and those skilled in the art can make their own choices as needed. The conductive layer 211 can be a single-layer metal structure, for example, the conductive layer 211 can include only one layer of aluminum. Alternatively, according to actual needs, the conductive layer 211 can also include a multi-layer metal structure, for example, the conductive layer 211 can include a first subsection and a second subsection arranged in a stacked manner, the first subsection includes molybdenum and / or titanium, and the second subsection includes aluminum.

[0125] Optionally, the etching rate of molybdenum and titanium is low, so that the first sub-portion extends outward relative to the second sub-portion, and the cross-section of the first portion 21 is trapezoidal, which is convenient for overlapping with the first electrode 32 formed by evaporation. When both the first sub-portion and the second portion 22 are made of titanium metal, the preparation process can be simplified.

[0126] In some embodiments, the cross-sectional area of ​​the first portion 21 gradually decreases in a direction away from the substrate 1 .

[0127] The cross section of the first part 21 may be a trapezoid, which increases the size of the defined opening 23. The cross section of the first part 21 may be a regular trapezoid, which can stably support the second part 22 on the one hand, and on the other hand, makes the contact surface area between the first sub-part and the second part 22 smaller, so that the first part 21 is concavely arranged relative to the second part 22 in a direction away from the central axis of the defined opening 23, which facilitates the disconnection of the second electrode 33 and the light-emitting functional layer 3 at the isolation structure 2.

[0128] In these optional embodiments, in order to obtain the first portion 21 with a concave setting, during the etching process, the second sub-portion has a faster etching rate relative to the first sub-portion and / or the second portion 22, thereby forming the concave first portion 21. Since the etching rate of the second sub-portion is faster, more waste generated by etching is easy to enter other positions of the display panel 100, thereby causing adverse effects. The orthographic projection of the second sub-portion on the substrate 1 is set to be within the orthographic projection of the first sub-portion on the substrate 1, so that the second sub-portion can be better supported on the first sub-portion, and the generated etching waste falls on the first sub-portion, which is easy to clean.

[0129] Optionally, the orthographic projection of the second portion 22 on the substrate 1 coincides with the orthographic projection of the first sub-portion on the substrate 1. The first sub-portion and the second portion 22 having the same area can be etched using the same mask, thereby simplifying the manufacturing process.

[0130] In some embodiments, the display panel 100 further includes a second flat layer 13, and the second electrode 33 is disposed on a side of the second flat layer 13 away from the substrate 1. The second flat layer 13 can flatten the driving circuit layer 12 so that the second electrode 33 can be formed on the plane provided by the second flat layer 13, which is conducive to forming the desired patterned second electrode 33. After the second electrode 33 is formed on the flat layer, the material C used to prepare the isolation structure 2 can cover the second electrode 33, and the material C is etched to form a limited opening 23 exposing the second electrode 33, and a light-transmitting opening 24, and to form a first part 21 and a second part 22. The light-emitting functional layer 3 can be prepared with reference to the preparation steps of the light-emitting functional layer 3 described above. The material C can be any one or more of titanium, aluminum, and molybdenum.

[0131] The isolation structure 2 may be directly disposed on a side of the second planar layer 13 facing away from the substrate 1 , and the isolation structure 2 may be supported by the second planar layer 13 .

[0132] In some embodiments, the display panel 100 further includes a pixel definition layer 9 disposed between the substrate 1 and the isolation structure 2 , the pixel definition layer 9 includes a pixel opening, and the orthographic projection of the pixel opening on the substrate 1 is located within the orthographic projection range of the limiting opening 23 on the substrate 1 .

[0133] The pixel definition layer 9 includes a pixel defining portion, which encloses a pixel opening. At least a portion of the light emitting portion 31 can be disposed in the pixel opening to achieve light emitting display of the display panel 100 , and the pixel opening can be disposed corresponding to the defining opening 23 .

[0134] In some embodiments, the isolation structure 2 is disposed on a side of the pixel definition layer 9 facing away from the substrate 1 , and the light-emitting functional layer 3 is at least partially disposed in the pixel opening.

[0135] The isolation structure 2 is arranged on the side of the pixel definition layer 9 facing away from the substrate 1, and the orthographic projection of the pixel opening on the substrate 1 is located within the orthographic projection of the limiting opening 23 on the substrate 1. The isolation structure 2 can be directly arranged on the side of the pixel definition layer 9 facing away from the substrate 1, and the isolation structure 2 is supported by the pixel definition layer 9. The orthographic projection of the pixel opening on the substrate 1 can be located within the orthographic projection of the limiting opening 23 on the substrate 1. The area of ​​the limiting opening 23 is larger than the area of ​​the pixel opening, which can reduce the influence of the isolation structure 2 on the light output viewing angle of the light-emitting functional layer 3.

[0136] Optionally, there are multiple pixel openings, which are spaced apart, and the isolation structure 2 can be disposed on at least part of the pixel defining portion between two adjacent pixel openings. Optionally, the isolation structure 2 can be disposed around at least part of the pixel openings.

[0137] In some embodiments, the pixel definition layer 9 is exposed from the light-transmitting opening 24 .

[0138] In some embodiments, the substrate 1 includes a substrate 11 and a driving circuit layer 12, the driving circuit layer 12 is arranged between the substrate 11 and the light-emitting functional layer 3, the driving circuit layer 12 includes a first conductive structure 127, and the projection of the first conductive structure 127 on the isolation structure 2 along the direction from the touch layer 4 to the substrate 1 at least partially falls into the light-transmitting opening 24.

[0139] The substrate 11 may be a silicon substrate, or a flexible substrate 11 such as polyimide. The driving circuit layer 12 and the light emitting device layer may include multiple layer structures, each of which may be formed by chemical vapor deposition, evaporation, or the like. Figure 5 The direction indicated by the X axis is the thickness direction of the display panel 100 . Those skilled in the art can form each layer structure in sequence along the thickness direction X starting from the substrate 11 .

[0140] The first conductive structure 127 is a portion of the driving circuit layer 12 that is spaced apart from the touch layer 4 through the light-transmitting opening 24 along the thickness direction of the display panel 100 . The light-transmitting shielding layer 5 can shield or reduce the radio frequency generated between the first conductive structure 127 and the touch layer 4 to a certain extent.

[0141] The projection of the first conductive structure 127 on the isolation structure 2 along the direction from the touch layer 4 to the substrate 1 at least partially falls into the light-transmitting opening 24 , so as to improve the shielding effect of the light-transmitting shielding layer 5 on the first conductive structure 127 .

[0142] In some embodiments, the touch layer 4 includes a first touch electrode layer 41 and a second touch electrode layer 42. The first touch electrode layer 41 and the second touch electrode layer 42 are spaced apart in a direction from the substrate 1 to the touch layer 4. The orthographic projection of the first touch electrode layer 41 on the substrate 1 at least partially overlaps with the orthographic projection of the isolation structure 2 on the substrate 1. The orthographic projection of the second touch electrode layer 42 on the substrate 1 at least partially overlaps with the orthographic projection of the isolation structure 2 on the substrate 1.

[0143] The first touch electrode layer 41 includes a plurality of first touch electrodes arranged at intervals, and the second touch electrode layer 42 includes a plurality of second touch electrodes arranged at intervals, and the first touch electrodes and the second touch electrodes are arranged at intervals along the first direction X, so as to form a touch capacitor. An insulating material is provided between the first touch electrodes and the second touch electrodes for insulation.

[0144] The orthographic projection of the first touch electrode layer 41 on the substrate 1 at least partially overlaps with the orthographic projection of the isolation structure 2 on the substrate 1, and the orthographic projection of the second touch electrode layer 42 on the substrate 1 at least partially overlaps with the orthographic projection of the isolation structure 2 on the substrate 1, so that at least part of the first touch electrode layer 41 or at least part of the second touch electrode layer 42 can be separated from the drive circuit layer 12 by the isolation structure 2 to reduce the generation of unnecessary radio frequency between the part of the first touch electrode layer 41 or the part of the second touch electrode layer 42 and the drive circuit layer 12.

[0145] In some embodiments, along the direction from the touch layer 4 to the substrate 1, the light-transmitting shielding layer 5 is blocked between the first touch electrode layer 41 and the first conductive structure 127, and the light-transmitting shielding layer 5 is blocked between the second touch electrode layer 42 and the first conductive structure 127, so as to improve the shielding effect of the light-transmitting shielding layer 5 between the first conductive structure 127 and the first touch electrode layer 41, and improve the shielding effect of the light-transmitting shielding layer 5 between the first conductive structure 127 and the second touch electrode layer 42.

[0146] In some embodiments, along the direction from the touch layer 4 to the substrate 1, the orthographic projection of the first touch electrode layer 41 on the substrate 1 does not overlap with the orthographic projection of the light-emitting portion 31 on the substrate 1, and the orthographic projection of the second touch electrode layer 42 on the substrate 1 does not overlap with the orthographic projection of the light-emitting portion 31 on the substrate 1, so as to avoid the first touch electrode layer 41 or the second touch electrode layer 42 affecting the light emission of the light-emitting portion 31.

[0147] In some embodiments, along the direction from the touch layer 4 to the substrate 1, the orthographic projection of the first touch electrode layer 41 on the substrate 1 is located within the orthographic projection range of the light-transmitting shielding layer 5 on the substrate 1, and the orthographic projection of the second touch electrode layer 42 on the substrate 1 is located within the orthographic projection range of the light-transmitting shielding layer 5 on the substrate 1, so that the side of the first touch electrode layer 41 close to the substrate 1 or the side of the second touch electrode layer 42 close to the substrate 1 can be shielded from radio frequency by the light-transmitting shielding layer 5.
