[0087] Embodiments of the present application provide a display panel 10, which can be an organic light emitting diode (OLED) display panel 10.

[0088] As shown in Figures 1 to 3 Embodiments of the first aspect of the present application provide a display panel 10, which has a display area AA and a non-display area NA, and includes a substrate 100 having a signal line and / or a driving circuit in the non-display area NA; a first electrode layer 200 disposed on one side of the substrate 100, the first electrode layer 200 including a first electrode 210 in the display area AA; an emitting layer 600 including an emitting unit 610 on a side of the first electrode 210 away from the substrate 100; an isolation structure 400 disposed on a side of the substrate 100 facing the first electrode layer 200, the isolation structure 400 being located in the display area AA and surrounding at least part of the emitting unit 610; a shielding structure 500 located in the non-display area NA, including a first shielding structure 510 and a second shielding structure 520 electrically connected to each other, at least part of the first shielding structure 510 being disposed in the same layer as the isolation structure 400, and the second shielding structure 520 being located in a different film layer from the first shielding structure 510; and a touch component 10a, at least part of the touch component 10a being located on a side of the shielding structure 500 away from the substrate 100.

[0089] In the display panel 10 provided by the embodiments of the present application, the display panel 10 has a display area AA and a non-display area NA, and includes a substrate 100, a first electrode layer 200, an isolation structure 400, an emitting layer 600, a shielding structure 500, and a touch component 10a. The first electrode layer 200 is disposed on one side of the substrate 100, and includes a first electrode 210 in the display area AA. The emitting layer 600 includes an emitting unit 610 on a side of the first electrode 210 away from the substrate 100, and the first electrode 210 can be used to participate in driving the emitting unit 610 to emit light. The isolation structure 400 is disposed on a side of the substrate 100 facing the first electrode layer 200, and is located in the display area AA and surrounds at least part of the emitting unit 610, so that the isolation structure 400 can be used to divide a sub-pixel of the display panel 10.

[0090] The shielding structure 500 is located in the non-display area NA. By arranging the at least partial touch component 10a on the side of the shielding structure 500 away from the substrate 100, the shielding structure 500 can better limit the signal in the substrate 100 from being transmitted to the touch component 10a, so as to better reduce the mutual interference between the signal of the signal line and / or the driving circuit in the substrate 100 and the touch signal in the touch component 10a. By arranging the at least partial first shielding structure 510 in the same layer as the isolation structure 400, the at least partial first shielding structure 510 can be prepared in the same process step as the isolation structure 400, so that the preparation process of the display panel 10 is simplified and the preparation efficiency of the display panel 10 is improved while the mutual interference between the touch signal and other signals in the display panel 10 is limited by arranging the first shielding structure 510.

[0091] In some embodiments of the present application, the shielding structure 500 is a conductive shielding structure. The first shielding structure 510 and the second shielding structure 520 can be electrically connected to each other, so that the first shielding structure 510 and the second shielding structure 520 located in different film layers are not easy to generate capacitance, and the shielding structure 500 itself is also not easy to interfere with the touch signal in the touch component 10a and the signal in the substrate 100, thereby better improving the working reliability of the display panel 10.

[0092] In some embodiments of the present application, the non-display area NA of the display panel 10 can be arranged around at least partial display area AA, for example, the non-display area NA can be located at the frame position of the display panel 10.

[0093] Optionally, the display panel 10 can further include a second electrode layer 700 located on the side of the light-emitting layer 600 away from the first electrode layer 200. The second electrode layer 700 can include a second electrode 710 located on the side of the light-emitting unit 610 away from the first electrode 210. Optionally, the isolation structure 400 can also be arranged around at least partial second electrode 710.

[0094] Optionally, the light-emitting unit 610 can include a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting structure, an electron injection layer (EIL), and an electron transport layer (ETL).

[0095] Optionally, the first electrode layer 200 and the second electrode layer 700 can be pixel electrode layers. One of the first electrode 210 and the second electrode 710 can serve as an anode, and the other of the first electrode 210 and the second electrode 710 can serve as a cathode to drive the light emitting unit 610 to emit light. Embodiments of the present application take the first electrode 210 as the anode of the display panel 10 and the second electrode 710 as the cathode of the display panel 10 as an example.

[0096] In some embodiments of the present application, the substrate 100 can be arranged in various ways. For example, the substrate 100 can include a planarization layer 130 and a driving circuit layer 120 located on a side of the planarization layer 130 away from the first electrode layer 200. Optionally, the substrate 100 can further include a substrate 110 arranged on a side of the driving circuit layer 120 away from the planarization layer 130. Optionally, the driving circuit layer 120 can include a first insulating layer 121, a second insulating layer 122, and a third insulating layer 123 arranged in layers. For example, the driving circuit layer 120 can further include a driving circuit, which can include a transistor 124, a storage capacitor 125, and a driving signal line for connecting various devices. The transistor 124 can include a semiconductor, a gate 124a, and a source / drain 124b. The storage capacitor 125 can include a first plate 125a and a second plate 125b. As an example, the gate 124a and the first plate 125a can be located on a side of the first insulating layer 121 facing the substrate 110, the second plate 125b can be located between the first insulating layer 121 and the second insulating layer 122, and the source / drain 124b can be located between the second insulating layer 122 and the third insulating layer 123.

[0097] Optionally, a projection of at least part of the driving circuit on the substrate 110 can be located within a projection of the shielding structure 500 on the substrate 110.

[0098] Optionally, the touch component 10a can include a touch electrode and a partial signal line connected to the touch electrode, such as a touch ground signal line, a touch driving signal line, a touch receiving signal line, and the like.

[0099] Optionally, the touch component 10a arranged in the non-display area NA and located on a side of the shielding structure 500 away from the substrate 100 can be shielded by the shielding structure 500 and less likely to interfere with signals in the driving circuit layer 120 of the display panel 10. For example, the shielding structure 500 can better shield the driving signals in the driving circuit layer 120 arranged in the non-display area NA, so that the touch signals of the touch component 10a are less likely to interfere with the driving signals in the driving circuit layer 120, thereby better improving the working reliability of the display panel 10.

[0100] In some embodiments of the present application, the material of the shielding structure 500 can include a conductive material, for example, the material of the first shielding structure 510 and the second shielding structure 520 can include a conductive material, so as to better improve the shielding effect of the shielding structure 500 on the touch signal and the driving signal in the display panel 10.

[0101] Optionally, the material of the first shielding structure 510 and the isolation structure 400 can both include a conductive material, so as to facilitate the preparation of the first shielding structure 510 and the isolation structure 400 in the same process step, and enable the adjacent second electrodes 710 to be connected to each other to form a surface electrode through the isolation structure 400, so as to facilitate the control of the second electrodes 710 in the display panel 10.

[0102] In some optional embodiments, in the case that the shielding structure 500 is a conductive shielding structure, the conductive shielding structure 500 can be connected to the direct current voltage signal end of the display panel 10, for example, the first shielding structure 510 and / or the second shielding structure 520 can be connected to the direct current voltage signal end of the display panel 10. By setting the shielding structure 500 to be connected to the direct current voltage signal end of the display panel 10, the direct current voltage signal end can provide a relatively stable voltage to the shielding structure 500, thereby improving the shielding effect of the shielding structure 500 on the touch signal and the driving signal in the display panel 10, and preventing the touch signal and the driving signal in the display panel 10 from interfering with each other.

[0103] As shown in FIG. 1, Figure 2 As shown in FIG. 1, Figure 3 In some optional embodiments, the signal line of the direct current voltage signal end can include at least one of a ground signal line, an initialization signal line, and a positive power voltage signal line, and the shielding structure 500 can be insulated from the isolation structure 400, so that when at least one of the ground signal line, the initialization signal line, and the positive power voltage signal line transmits a signal to the shielding structure 500, the signal in the shielding structure 500 is less likely to affect the signal in the second electrode 710 in the display panel 10 through the isolation structure 400, thereby improving the light-emitting display reliability of the display panel 10.

[0104] In this optional embodiment, the shielding structure 500 and the isolation structure 400 can be insulated in various ways, for example, the shielding structure 500 can be spaced apart from the isolation structure 400, or an insulating material can be provided between the shielding structure 500 and the isolation structure 400 to achieve insulation, which is not limited in the present application.

[0106] like Figure 4 and Figure 5 As shown, in some alternative embodiments, the signal line of the DC voltage signal terminal may include a negative power supply voltage signal line, and the first shielding structure 510 may be connected to the isolation structure 400, so that the second electrode 710 of the display panel 10 can receive the negative power supply voltage signal (ELVSS) transmitted by the negative power supply voltage signal line through the isolation structure 400 and the first shielding structure 510 in sequence, so as to realize the light emission display of the display panel 10 and facilitate the arrangement of signal lines in the display panel 10.

[0107] Optionally, the first shielding structure 510 can be integrated with the isolation structure 400, so that the first shielding structure 510 and the isolation structure 400 can be fabricated in the same process step, which can simplify the fabrication process of the display panel 10 and improve the fabrication efficiency of the display panel 10.

[0108] Optionally, the second shielding structure 520 can also be connected to the isolation structure 400 to reduce the resistance during the transmission of negative power supply voltage signals.

[0109] In some embodiments of this application, the second shielding structure 520 can be positioned in various ways, with the second shielding structure 520 located on the side of the first shielding structure 510 facing the substrate 100. For example, the second shielding structure 520 can be disposed between the first shielding structure 510 and the driving circuit.

[0110] Optionally, since the second shielding structure 520 is located on the side of the first shielding structure 510 facing the substrate 100, the second shielding structure 520 can be connected to a DC voltage signal terminal to facilitate the connection between the shielding structure 500 and the DC voltage signal terminal of the display panel 10. The first shielding structure 510, which is connected to the second shielding structure 520, can be connected to the DC voltage signal terminal through the second shielding structure 520.

[0111] like Figure 5 As shown, in some optional embodiments, the second shielding structure 520 may be disposed within the substrate 100. Optionally, the second shielding structure 520 may be disposed between any two film layers of the substrate 100 on the side of the driving circuit away from the substrate 110. For example, the second shielding structure 520 may be disposed between the planarization layer 130 and the third insulating layer 123.

[0113] like Figure 6As shown, in some other optional embodiments, the second shielding structure 520 can be disposed on the side of the substrate 100 facing the first electrode layer 200, for example, the second shielding structure 520 is disposed in the same layer as the first electrode layer 200. By disposing the second shielding structure 520 in the same layer as the first electrode layer 200, the second shielding structure 520 can be prepared in the same process step as the first electrode layer 200, so that the second shielding structure 520 is used to limit the mutual interference between the touch signal and other signals in the display panel 10, while simplifying the preparation process of the display panel 10 and improving the preparation efficiency of the display panel 10.

[0114] Optionally, the second shielding structure 520 has the same shape as the first electrode 210; and / or, the second shielding structure 520 has the same size as the first electrode 210, so that the second shielding structure 520 can be prepared in the same process step as the first electrode 210 using the same processing equipment, which can further improve the preparation efficiency of the display panel 10.

[0115] For ease of description, the following embodiments are described by taking the second shielding structure 520 disposed in the same layer as the first electrode layer 200 as an example.

[0116] In some optional embodiments, the isolation structure 400 can be used to isolate the material of the adjacent light emitting unit 610 and the material of the second electrode 710. Wherein, the isolation structure 400 can enclose the isolation opening 400a, and the orthographic projection of the light emitting unit 610 and the second electrode 710 on the isolation structure 400 can be located in the isolation opening 400a.

[0117] Optionally, the isolation structure 400 includes an isolation portion 410, the isolation portion 410 includes a first end portion 410a facing the substrate 100 and a second end portion 410b away from the substrate 100, and the orthographic projection of the first end portion 410a on the substrate 100 is located in the orthographic projection of the second end portion 410b on the substrate 100.

[0118] In these optional embodiments, by disposing the orthographic projection of the first end portion 410a of the isolation structure 400 on the substrate 100 in the orthographic projection of the second end portion 410b of the isolation structure 400 on the substrate 100, the second end portion 410b can shield at least part of the material used to prepare the light emitting layer 600 when the light emitting layer 600 and the second electrode layer 700 of the display panel 10 are evaporated, so as to isolate the light emitting layer 600 between adjacent sub-pixels, and facilitate the formation of a plurality of spaced light emitting units 610, thereby eliminating the need to use a mask plate with high precision when evaporating the light emitting layer 600 of the display panel 10, for example, eliminating the need to use a fine metal mask (FMM) when evaporating the light emitting layer 600, thereby reducing the production cost of the display panel 10.

[0119] Figure 7 This is a schematic diagram of a shielding structure 500 provided in an embodiment of this application.

[0120] like Figure 6 and Figure 7 As shown, in some optional embodiments, the first shielding structure 510 encloses to form a shielding opening 510a, and at least a portion of the second shielding structure 520 is projected onto the first shielding structure 510 within the shielding opening 510a.

[0121] By providing a shielding opening 510a, the first shielding structure 510 and the shielding opening 510a formed by the first shielding structure 510 can be fabricated simultaneously during the fabrication of the isolation structure 400 and the isolation opening 400a formed by the isolation structure 400. This allows the first shielding structure 510 to be fabricated in the same process step as the isolation structure 400, thereby improving the fabrication efficiency of the display panel 10. By providing at least a portion of the second shielding structure 520 with its orthographic projection on the first shielding structure 510 located within the shielding opening 510a, the second shielding structure 520 can effectively block the shielding opening 510a in the thickness direction X of the display panel 10. This provides better shielding and blocking between the touch signal and other signals in the display panel 10, making it less likely for the touch signal and other signals in the display panel 10 to interfere with each other through the shielding opening 510a, thereby further improving the operational reliability of the display panel 10.

[0122] Optionally, the orthographic projection of the shielding opening 510a on the substrate 100 is located within the orthographic projection of the second shielding structure 520 on the substrate 100, so as to further enhance the shielding effect of the second shielding structure 520 on the shielding opening 510a, so as to play a better shielding and blocking role between the touch signal and other signals in the display panel 10.

[0123] Optionally, there may be multiple second shielding structures 520, which are spaced apart. The first shielding structure 510 surrounds at least a portion of the second shielding structure 520, so that the second shielding structure 520 can have a similar shape and arrangement to the first electrode 210. This allows the second shielding structure 520 and the first electrode 210 to be fabricated together, making it easier for the second shielding structure 520 and the first electrode layer 200 to be fabricated in the same process step.

[0124] Optionally, the second shielding structure 520 can be made of the same layer and material as the first electrode 210, so as to further facilitate the preparation of the second shielding structure 520 and the first electrode layer 200 in the same process step.

[0125] In some optional embodiments, the shape of the first shielding structure 510 can be approximately the shape of the isolation structure 400, such that the shielding opening 510a formed by the first shielding structure 510 can have a similar shape to the isolation opening 400a formed by the isolation structure 400. This allows the shielding opening 510a and the isolation opening 400a to be prepared using similar or the same manufacturing process, thereby enabling the shielding opening 510a and the isolation opening 400a to be prepared in the same process step. This further simplifies the manufacturing process of the display panel 10 and improves the manufacturing efficiency of the display panel 10.

[0126] Optionally, the first shielding structure 510 includes a first sub-part 511 disposed on the same layer as the isolation portion 410. The first sub-part 511 includes a third end 511a facing the substrate 100 and a fourth end 511b away from the substrate 100. The orthographic projection of the third end 511a on the substrate 100 is located within the orthographic projection of the fourth end 511b on the substrate 100, so that the first shielding structure 510 can approximate the shape of the isolation structure 400, so that the first shielding structure 510 and the isolation structure 400 can be fabricated in the same process step.

[0127] In some embodiments of this application, the isolation portion 410 and the first sub-portion 511 are arranged in various shapes. Among them, the shape of the isolation portion 410 can be any shape of material capable of blocking and isolating the light-emitting layer 600.

[0128] like Figure 6 As shown, in some embodiments, in the direction away from the substrate 100, the distance between the surfaces of the isolation portion 410 toward the two sides of the light-emitting unit 610 gradually increases, and the distance between the surfaces of the first sub-portion 511 toward the two sides of the second shielding structure 520 gradually increases, so as to form a shape in which the orthographic projection of the first end portion 410a of the isolation portion 410 on the substrate 100 is located within the orthographic projection of the second end portion 410b on the substrate 100, and to form a shape in which the orthographic projection of the third end portion 511a of the first sub-portion 511 on the substrate 100 is located within the orthographic projection of the fourth end portion 511b on the substrate 100.

[0129] Figure 8 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0130] like Figure 8As shown, in some other embodiments, the isolation structure 400 includes a first isolation portion 411 and a second isolation portion 412 disposed on the side of the first isolation portion 411 away from the substrate 100. The orthographic projection of the first isolation portion 411 on the substrate 100 is located within the orthographic projection of the second isolation portion 412 on the substrate 100, and the second isolation portion 412 protrudes out of the first isolation portion 411 toward the light-emitting unit 610. The first sub-part 511 includes a first shielding portion 511c and a second shielding portion 511d disposed on the side of the first shielding portion 511c away from the substrate 100. The orthographic projection of the first shielding portion 511c on the substrate 100 is located within the orthographic projection of the second shielding portion 511d on the substrate 100, and the second shielding portion 511d protrudes out of the first shielding portion 511c toward the shielding opening 510a.

[0131] Optionally, the first end 410a may be located in the first isolation portion 411, and the second end 410b may be located in the second isolation portion 412. Optionally, the third end 511a may be located in the first shielding portion 511c, and the fourth end 511b may be located in the second shielding portion 511d.

[0132] By providing a second isolation portion 412 that protrudes from the first isolation portion 411 toward the light-emitting unit 610, that is, by providing a second isolation portion 412 that protrudes from the first isolation portion 411 toward the isolation opening 400a, the second isolation portion 412 can better shield and isolate the material of the light-emitting layer 600, making it difficult for the material of the light-emitting layer 600 to be continuous between the second isolation portion 412 and the first isolation portion 411, thereby further improving the isolation effect of the isolation structure 400 on the material of the light-emitting layer 600.

[0133] Optionally, the first shielding part 511c and the first isolation part 411 are disposed in the same layer and made of the same material, and / or the second shielding part 511d and the second isolation part 412 are disposed in the same layer and made of the same material, so that the first sub-part 511 and the isolation part 410 can be prepared in the same process step.

[0134] like Figure 8 As shown, in some optional embodiments, the first shielding structure 510 can be connected to the second shielding structure 520 through a via 10b, so that the first shielding structure 510 and the second shielding structure 520 are less likely to generate capacitance, and the shielding structure 500 itself is less likely to interfere with the touch signal in the touch component 10a and the signal in the substrate 100, thereby improving the working reliability of the display panel 10.

[0135] Figure 9 This is a partial structural diagram of a second pixel limiting portion 320 provided in an embodiment of this application.

[0136] like Figure 8 and Figure 9As shown, optionally, the via 10b can be arranged around at least part of the second shielding structure 520, so that the material in the via 10b for connecting the first shielding structure 510 and the second shielding structure 520 can also play a better shielding and shielding effect between the touch signal and other signals in the display panel 10, so that the touch signal and other signals in the display panel 10 are not easy to interfere with each other at the gap between the first shielding structure 510 and the second shielding structure 520, thereby further improving the working reliability of the display panel 10.

[0137] For example, the via 10b can be arranged around at least part of the second shielding structure 520, and at least part of the first shielding structure 510 can be connected with the second shielding structure 520 in the via 10b, so that the first shielding structure 510 in the via 10b can also play a better shielding and shielding effect between the touch signal and other signals in the display panel 10, so that the touch signal and other signals in the display panel 10 are not easy to interfere with each other at the gap between the first shielding structure 510 and the second shielding structure 520, so that the shielding structure 500 can be more continuous at the non-display area NA. Shielding effect.

[0138] Optionally, the orthographic projection of the first shielding structure 510 on the substrate 100 and the orthographic projection of the second shielding structure 520 on the substrate 100 are at least partially overlapped, so as to facilitate the connection of the first shielding structure 510 and the second shielding structure 520 through the via 10b.

[0139] In some optional embodiments, the first shielding structure 510 includes a first sub-portion 511 and a second sub-portion 512 located on the side of the first sub-portion 511 facing the substrate 100, and the second sub-portion 512 is connected with the second shielding structure 520 through the via 10b.

[0140] Optionally, the second sub-portion 512 is arranged protruding from the first sub-portion 511 towards the shielding opening 510a.

[0141] Optionally, the orthographic projection of the second sub-portion 512 on the substrate 100 and the orthographic projection of the second shielding structure 520 on the substrate 100 are at least partially overlapped.

[0142] By arranging the second sub-portion 512 to protrude from the first sub-portion 511 towards the shielding opening 510a, the second sub-portion 512 can have a better extension size, so that the second sub-portion 512 can be better located above the second shielding structure 520, that is, the orthographic projection of the second sub-portion 512 on the substrate 100 and the orthographic projection of the second shielding structure 520 on the substrate 100 can be at least partially overlapped, thereby facilitating the connection of the second sub-portion 512 and the second shielding structure 520 through the via 10b, to realize the connection of the first shielding structure 510 and the second shielding structure 520.

[0143] Optionally, the isolation structure 400 includes an isolation portion 410 and a conductive portion 420 located on the side of the isolation portion 410 facing the substrate 100. The conductive portion 420 protrudes from the isolation portion 410 toward the light-emitting unit 610. By providing the conductive portion 420 to protrude from the isolation portion 410 toward the light-emitting unit 610, that is, by providing the conductive portion 420 to protrude from the isolation opening 400a, it is easier for the second electrode 710 to overlap with the conductive portion 420, and the overlap area between the conductive portion 420 and the second electrode 710 can be increased, thereby reducing the overlap resistance of the display panel 10. This facilitates electrical connection between adjacent second electrodes 710 through the isolation portion 410.

[0144] Optionally, the second sub-part 512 and the conductive part 420 are disposed in the same layer and made of the same material, so that the second sub-part 512 and the conductive part 420 can be prepared in the same process step.

[0145] like Figure 8 and Figure 9 As shown, in some optional embodiments, the display panel 10 further includes a pixel definition layer 300 disposed on the side of the first electrode layer 200 away from the substrate 100. The pixel definition layer 300 includes a first pixel defining portion 310 located in the display area AA and a second pixel defining portion 320 located in the non-display area NA. The first pixel defining portion 310 has a pixel opening 311, and at least a portion of the first electrode 210 is exposed through the pixel opening 311. At least a portion of the second pixel defining portion 320 is located on the side of the second shielding structure 520 away from the substrate 100.

[0146] Optionally, the first shielding structure 510 is disposed on the side of the second pixel limiting portion 320 away from the substrate 100, and the first shielding structure 510 and the second shielding structure 520 are connected through a through hole 10b penetrating the second pixel limiting portion 320.

[0147] In these optional embodiments, at least a portion of the light-emitting unit 610 may be disposed within the pixel opening 311, and the first electrode 210 exposed from the pixel opening 311 of the first pixel defining portion 310 may be used to drive the light-emitting unit 610 to emit light. By providing at least a portion of the second pixel defining portion 320 located on the side of the second shielding structure 520 away from the substrate 100, the second pixel defining portion 320 can provide better protection for the second shielding structure 520 during the fabrication of the first shielding structure 510, for example, during the fabrication of the shielding opening 510a of the first shielding structure 510, making it less likely for the etching material to damage the second shielding structure 520.

[0148] In some optional embodiments, the second pixel defining portion 320 is provided with a through hole 340. The through hole 340 can be used to release the water vapor in the display panel 10, so that the display panel 10 is not easily damaged by water vapor pressure. For example, the through hole 340 can be used to release the water vapor generated in the rework process (such as baking) of the partial organic material layer structure (such as the planarization layer 130) of the display panel 10. The through hole 340 can also be used to release the water vapor generated in the reliability test (simulating user usage scenarios) of the display panel 10.

[0149] Optionally, the through hole 340 can be located on the side of the shielding structure 500 away from the display area AA.

[0150] Optionally, the orthographic projection of the shielding structure 500 on the pixel defining layer 300 is misaligned with the through hole 340.

[0151] By reasonably setting the position of the through hole 340, the through hole 340 can be set without affecting the continuity of the shielding structure 500, so that the shielding structure 500 can better limit the transmission of signals in the substrate 100 to the touch assembly 10a.

[0152] In some optional embodiments, the through hole 340 can be arranged around at least part of the shielding structure 500, so that the through hole 340 can have a better extension size to improve the release effect of the through hole 340 on the water vapor.

[0153] In this optional embodiment, the through hole 340 can have various arrangement shapes, for example, the through hole 340 can be annular to better surround the shielding structure 500. Or for example, the number of through holes 340 is multiple, and the multiple through holes 340 are arranged at intervals around the shielding structure 500.

[0154] Figure 10 is a partial cross-sectional view of a display panel 10 provided by another embodiment of the present application.

[0155] As shown in Figure 10 In some optional embodiments, the display panel 10 further includes a first encapsulation layer 810, and at least part of the first encapsulation layer 810 is arranged on the side of the shielding structure 500 away from the substrate 100.

[0156] Optionally, the material of the first encapsulation layer 810 includes an inorganic material.

[0157] In these optional embodiments, by arranging the first encapsulation layer 810 covering the shielding structure 500, compared with the conductive material (such as metal material) of the shielding structure 500, the first encapsulation layer 810 can be better covered and fitted by the material of the other film layers prepared subsequently, so that the other film layers prepared subsequently are not easy to peel off and fall off, thereby the structural reliability of the display panel 10 can be better improved.

[0158] Optionally, the display panel 10 further comprises a third encapsulation layer 830 disposed on the side of the first encapsulation layer 810 away from the substrate 100, and the third encapsulation layer 830 can also be used for encapsulation of the display panel 10. Optionally, the material of the third encapsulation layer 830 comprises an organic material, i.e., the third encapsulation layer 830 can be an organic encapsulation layer, and the overall thickness of the display panel 10 can be adjusted so that the surface of the third encapsulation layer 830 away from the substrate 100 is smoother.

[0159] In these optional embodiments, by disposing the first encapsulation layer 810 covering the shielding structure 500, the first encapsulation layer 810 can be better covered and fitted by the material of the third encapsulation layer 830 compared with the conductive material (such as metal material) of the shielding structure 500 when the third encapsulation layer 830 is subsequently prepared, so that the third encapsulation layer 830 subsequently prepared is not prone to peeling and falling off, thereby better improving the structural reliability of the display panel 10.

[0160] Optionally, the display panel 10 further comprises a second encapsulation layer 820, and the second encapsulation layer 820 comprises a second encapsulation portion 821 located in the display area AA and disposed on the side of the light-emitting layer 600 away from the substrate 100. Specifically, the second encapsulation portion 821 can be located on the side of the second electrode 710 away from the substrate 100. By disposing the second encapsulation layer 820, the light-emitting unit 610 and the second electrode 710 in the isolation opening 400a can be better encapsulated by the second encapsulation portion 821, so that external interference substances (such as water vapor) are not prone to damage the light-emitting unit 610 and the second electrode 710 in the isolation opening 400a, thereby better improving the working reliability of the display panel 10.

[0161] In some embodiments, in the preparation process of the display panel 10, the second encapsulation layer 820 can be prepared first, and then the entire first encapsulation layer 810 is prepared, i.e., the first encapsulation layer 810 can be disposed in the display area AA and the non-display area NA, so that the first encapsulation layer 810 can have a better covering effect, and at least part of the first encapsulation layer 810 can be disposed on the side of the second encapsulation layer 820 away from the substrate 100, so that the first encapsulation layer 810 can also better participate in the encapsulation of the light-emitting unit 610 and the second electrode 710 in the isolation opening 400a to further improve the encapsulation effect of the display panel 10.

[0162] Optionally, the material of the second encapsulation layer 820 comprises an inorganic material.

[0163] Optionally, the first encapsulation layer 810 and the second encapsulation layer 820 are made of the same material. By setting the first encapsulation layer 810 and the second encapsulation layer 820 to be made of the same material, the first encapsulation layer 810 can be better bonded to the second encapsulation layer 820, making the first encapsulation layer 810 less prone to peeling and falling off.

[0164] Optionally, the thickness of the first encapsulation layer 810 may be less than the thickness of the second encapsulation layer 820, so that the first encapsulation layer 810 located in the non-display area NA is not likely to have an excessively large thickness, thereby reducing the impact of the first encapsulation layer 810 on the subsequent manufacturing of the display panel 10. For example, the impact of the first encapsulation layer 810 on subsequent cutting or bending processes may be reduced.

[0165] like Figure 10 As shown, in some optional embodiments, the display panel 10 further includes a dam 900 located in the non-display area NA and disposed on the side of the substrate 100 facing the first electrode layer 200, the dam 900 surrounding at least a portion of the shielding structure 500. By providing the dam 900, the organic material in the third encapsulation layer 830 can be better confined within the dam 900.

[0166] Optionally, the dam 900 may be disposed on the side of the drive circuit layer 120 facing the planarization layer 130. Optionally, the dam 900 may be spaced apart from the planarization layer 130 to facilitate the limiting effect of the dam 900 on the organic material in the third encapsulation layer 830.

[0167] Optionally, at least a portion of the dam 900 may be disposed on the same layer and made of the same material as the planarization layer 130 to further simplify the manufacturing process of the display panel 10 and improve the manufacturing efficiency of the display panel 10. For example, the dam 900 may be formed by stacking multiple layers of materials. In the direction away from the driving circuit layer 120, the dam 900 may include a first dam layer 910 and a second dam layer 920 stacked sequentially. During the fabrication of the planarization layer 130, at least a portion of the material of the planarization layer 130 may fall onto the first dam layer 910 to form the second dam layer 920.

[0168] Optionally, the pixel definition layer 300 may also include a third pixel limiting part 330 disposed above the second dam layer 920. The third pixel limiting part 330 may also have a through hole 340 to release moisture in the display panel 10, so that the display panel 10 is not easily damaged by moisture pressure.

[0169] In some optional embodiments, the surface of the dam 900 away from the driving circuit layer 120 has a first spacing L1 with the surface of the driving circuit layer 120 facing the planarization layer 130, and the maximum spacing between the surface of the shielding structure 500 away from the driving circuit layer 120 and the surface of the driving circuit layer 120 facing the planarization layer 130 is a second spacing L2, and the second spacing L2 is greater than the first spacing L1.
