A driving circuit layer may be provided on one side of the substrate 11 close to the isolation structure layer, and the driving circuit layer includes a pixel driving circuit, and the pixel driving circuit includes a thin film transistor.
[0133] It should be noted that the isolation structure 12 refers to a structure that can separate adjacent light-emitting functional parts 13. Multiple light-emitting functional parts 13 are correspondingly arranged at multiple first openings 12a1. Adjacent light-emitting functional parts 13 can be separated by the isolation structure 12, thereby avoiding crosstalk between adjacent light-emitting functional parts 13 and improving the display effect of the display panel 10. In addition, by providing an isolation structure layer, the isolation structure layer includes an isolation structure 12 and multiple first openings 12a1 formed by the isolation structure 12, and the light-emitting functional part 13 can be manufactured by a patterned photolithography process, thereby eliminating FMM, which is beneficial to improving PPI. In addition, since the light-emitting functional part 13 is manufactured by a patterned photolithography process, compared with the display panel 10 that uses FMM to evaporate the light-emitting functional part 13, the shape of the light-emitting functional part 13 can be made richer and the arrangement method can be more optimized, thereby improving the display effect.
[0134] It is understood that the light-emitting functional part 13 includes multiple functional layers, including a light-emitting layer (Emissionlayer, EML), and further, may include one or more of a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole blocking layer (HBL) and an electron blocking layer (EBL). Alternatively, the light-emitting functional part 13 may also be a laminated light-emitting layer, that is, including at least two light-emitting layers and a charge generation layer (CGL) located between each adjacent light-emitting layer.
[0135] When the isolation structure 12 transmits signals, the isolation structure 12 generates an electric field. By making the first insulating layer 161 cover the first touch portion 141, the interference between the electric field generated by the isolation structure 12 and the electric field generated by the first touch portion 141 can be reduced, thereby improving the display effect and touch effect of the display panel 10.
[0136] The first protective layer 162 is at least provided on at least part of the side wall of the first wiring 15, so that the first protective layer 162 can at least protect at least part of the side wall of the first wiring 15, so that in the process of manufacturing the display panel 10, the erosion of the side wall of the first wiring 15 by the process solution (such as etching solution) can be weakened, thereby reducing the risk of package failure caused by the erosion of the first wiring 15, and improving the display effect and reliability of the display panel 10. The first protective layer 162 is provided on the same layer as the first insulating layer 161, that is, the first protective layer 162 and the first insulating layer 161 are obtained by patterning the same film layer, so that the use of the mask plate can be reduced, the mask process can be saved, and the number of film layers of the display panel 10 can be reduced, thereby improving the manufacturing efficiency of the display panel 10, reducing the manufacturing cost of the display panel 10, and facilitating the thinness of the display panel 10.
[0137] In summary, the display panel 10 provided in the embodiment of the present application is provided with a first insulating layer 161 and a first protective layer 162 distributed on the same layer, so that the first insulating layer 161 at least covers a portion of the first touch portion 141; the orthographic projection of the first protective layer 162 on the substrate 11 at least covers a portion of the orthographic projection of the first wiring 15 on the substrate 11, so that the first insulating layer 161 and the first protective layer 162 can be obtained by patterning the same film layer, and can protect the first touch portion 141 and the first wiring 15. In this way, on the one hand, the corrosion of the side wall of the first wiring 15 by the process solution in the display panel 10 manufacturing process can be weakened, and the risk of packaging failure caused by the corrosion of the first wiring 15 can be reduced, thereby improving the reliability and display effect of the display panel 10; on the other hand, the interference between the electric field generated by the isolation structure 12 when transmitting the signal and the electric field generated by the first touch part 141 can be reduced, thereby improving the display effect and touch effect of the display panel 10; in addition, the use of mask plates can be reduced, saving mask processes, and reducing the number of film layers of the display panel 10, thereby improving the production efficiency of the display panel 10, reducing the production cost of the display panel 10, and facilitating the thinning of the display panel 10.
[0138] See also Figure 1 and Figure 3In one embodiment, the display panel 10 also includes a dam structure 17 disposed on one side of the substrate 11, and at least a portion of the dam structure 17 is located in the first non-display area 10b; the first wiring 15 includes a first sub-portion 151 and a second sub-portion 152 that are interconnected; the orthographic projection of the first sub-portion 151 on the substrate 11 overlaps with the orthographic projection of the dam structure 17 on the substrate 11; the second sub-portion 152 is located on a side of the dam structure 17 away from the display area 10a; the first protective layer 162 includes a first protective portion 1621, and the first protective portion 1621 is at least disposed on at least a portion of the side wall of the second sub-portion 152.
[0139] Water vapor usually invades the display area 10a of the display panel 10 from the edge of the display panel 10. Under the action of water vapor, harmful ions are easily diffused to the metal wires at the edge of the display panel, making the metal wires at the edge of the display panel 10 easily corroded. In this embodiment, by providing the dam structure 17, the organic film layer with greater fluidity located on the side of the dam structure 17 close to the display area 10a can be effectively blocked. In this way, the organic film layer can be prevented from overflowing to an undesirable area, and water vapor can be prevented from invading the interior of the display panel 10 through the organic film layer, thereby reducing the probability of water vapor invading the display area 10a, thereby improving the reliability of the display panel 10. In addition, by providing the first protection portion 1621 so that the first protection portion 1621 is at least provided on at least a portion of the side wall of the second sub-portion 152, the second sub-portion 152 can be protected, thereby reducing the erosion of the side wall of the second sub-portion 152 by the process solution in the display panel 10 process, thereby reducing the risk of packaging failure caused by the erosion of the second sub-portion 152, and further reducing the probability of metal corrosion of the second sub-portion 152, reducing the probability of poor display of the display panel 10, and improving the reliability and display effect of the display panel 10.
[0140] See also Figures 3 to 6 In some embodiments, the first protection portion 1621 is disposed on a side wall of the second sub-portion 152 and extends to a side of the second sub-portion 152 facing away from the substrate 11 .
[0141] Therefore, the first protection portion 1621 can not only provide protection for the side wall of the second sub-portion 152, but also provide protection for the side of the second sub-portion 152 facing away from the substrate 11. In this way, the erosion of the side wall of the second sub-portion 152 by the process solution in the display panel 10 process can be further weakened, and the risk of packaging failure caused by the erosion of the second sub-portion 152 can be further reduced, thereby further improving the reliability and display effect of the display panel 10.
[0142] See also Figures 3 to 6 In some embodiments, the first protection portion 1621 covers a side of the second sub-portion 152 facing away from the substrate 11 .
[0143] Therefore, the first protective portion 1621 can provide effective protection for the side wall of the second sub-portion 152 and the side of the second sub-portion 152 facing away from the substrate 11, greatly reducing the corrosion of the second sub-portion 152 by the process solution in the display panel 10 process, effectively reducing the risk of packaging failure caused by the corrosion of the second sub-portion 152, and improving the reliability and display effect of the display panel 10.
[0144] See also Figure 1 and Figure 3 In some embodiments, the dam structure 17 includes a plurality of dams 171 arranged at intervals in a direction from the display area 10a to the first non-display area 10b.
[0145] Therefore, by making the dam structure 17 include a plurality of dams 171 arranged at intervals along the direction pointing from the display area 10a to the first non-display area 10b, the organic film layer can be blocked at multiple levels in the direction pointing from the display area 10a to the first non-display area 10b, thereby preventing the organic film layer from overflowing to the side of the dam structure 17 away from the display area 10a, thereby reducing the probability of water vapor invading the display area 10a through the organic film layer, thereby improving the reliability of the display panel 10.
[0146] See also Figure 3 In some embodiments, the first sub-portion 151 includes a plurality of first sub-segments 1511 and at least one second sub-segment 1512, and the first sub-segments 1511 and the second sub-segments 1512 are connected; the orthographic projection of the first sub-segment 1511 on the substrate 11 is located within the orthographic projection of the dam 171 on the substrate 11; the second sub-segments 1512 and the multiple dams 171 are alternately arranged in a direction from the display area 10a to the first non-display area 10b.
[0147] See also Figure 3 In some embodiments, the first protection layer 162 further includes at least one second protection portion 1622 , and the second protection portion 1622 is at least disposed on at least a portion of the side wall of the second sub-segment 1512 .
[0148] In this way, the second sub-segment 1512 can be protected, thereby reducing the erosion of the side wall of the second sub-segment 1512 by the process solution in the display panel 10 process, thereby reducing the risk of packaging failure caused by the erosion of the second sub-segment 1512, and further reducing the probability of metal corrosion of the second sub-segment 1512, reducing the probability of poor display of the display panel 10, and improving the reliability and display effect of the display panel 10.
[0149] See also Figures 3 to 6 In some embodiments, the second protection portion 1622 is disposed on a side wall of the second sub-segment 1512 and extends to a side of the second sub-segment 1512 facing away from the substrate 11 .
[0150] Therefore, the second protection portion 1622 can not only provide protection for the side wall of the second sub-segment 1512, but also provide protection for the side of the second sub-segment 1512 facing away from the substrate 11. In this way, the erosion of the side wall of the second sub-segment 1512 by the process solution in the display panel 10 process can be further weakened, and the risk of packaging failure caused by the erosion of the second sub-segment 1512 can be further reduced, thereby further improving the reliability of the display panel 10.
[0151] See also Figures 3 to 6 In some embodiments, the second protection portion 1622 covers a side of the second sub-segment 1512 facing away from the substrate 11 .
[0152] Therefore, the second protection portion 1622 can provide effective protection for the side wall of the second sub-segment 1512 and the side of the second sub-segment 1512 facing away from the substrate 11, greatly reducing the corrosion of the second sub-segment 1512 by the process solution in the display panel 10 process, effectively reducing the risk of packaging failure caused by the corrosion of the second sub-segment 1512, and improving the reliability of the display panel 10.
[0153] See also Figure 3 In some embodiments, the first protective layer 162 further includes a plurality of third protective portions 1623 , which correspondingly cover a side of the plurality of first sub-segments 1511 away from the substrate 11 ; the plurality of third protective portions 1623 are connected to the second protective portions 1622 and the first protective portions 1621 .
[0154] Thus, the first protective layer 162 can be a continuous film layer and provide protection for the first wiring 15, thereby reducing the corrosion of the side wall of the first wiring 15 by the process solution in the display panel 10 manufacturing process, thereby reducing the risk of packaging failure caused by the corrosion of the first wiring 15 and improving the reliability of the display panel 10.
[0155] See also Figure 3 In some embodiments, the dam 171 includes a first sublayer 1711 and a second sublayer 1712, the first sublayer 1711 is located on a side of the first subsegment 1511 close to the substrate 11; the second sublayer 1712 is located on a side of the first subsegment 1511 away from the substrate 11; the third protective portion 1623 covers the side of the second sublayer 1712 away from the substrate 11.
[0156] Therefore, the second sublayer 1712 and the third protective portion 1623 can form a double-layer protection for the first sub-segment 1511, which greatly reduces the erosion of the side wall of the first sub-segment 1511 by the process solution in the display panel 10 process, thereby reducing the risk of packaging failure caused by the erosion of the first sub-segment 1511 and improving the reliability of the display panel 10.
[0157] See also Figure 1In some embodiments, the dam structure 17 is disposed around the display area 10a. In a specific example, the dam 171 is an annular structure, and the dam 171 is disposed around the display area 10a.
[0158] Therefore, the dam structure 17 can effectively block the organic film layer outside the display area 10 a, prevent the organic film layer from overflowing to an unexpected area, and block moisture from invading the display area 10 a, thereby improving the reliability of the display panel 10 .
[0159] In some embodiments, the material of the first protection layer 162 includes an inorganic material. In a specific example, the material of the first protection layer 162 can be silicon oxide, silicon nitride, etc.
[0160] Therefore, the first protective layer 162 can isolate water vapor and oxygen, thereby improving the packaging reliability of the display panel 10 .
[0161] See also Figures 3 to 6 In one embodiment, the display panel 10 further includes a fourth protecting portion 181 , which covers at least a portion of a side wall of the second sub-portion 152 ; and the first protecting portion 1621 is located on a side of the fourth protecting portion 181 facing away from the substrate 11 .
[0162] Therefore, the first protection portion 1621 and the fourth protection portion 181 can form a double-layer protection for the second sub-portion 152, so that the erosion of the side wall of the second sub-portion 152 by the process solution in the display panel 10 process can be effectively reduced, thereby reducing the risk of packaging failure caused by the erosion of the second sub-portion 152, reducing the probability of corrosion of the second sub-portion 152, and improving the reliability and display effect of the display panel 10.
[0163] See also Figures 3 to 6 In some embodiments, the fourth protection portion 181 covers the sidewall of the second sub-portion 152 and extends to the surface of the second sub-portion 152 facing away from the substrate 11 .
[0164] Therefore, the first protection portion 1621 and the fourth protection portion 181 can form a double-layer protection for the side wall of the second sub-portion 152 and the side of the second sub-portion 152 facing away from the substrate 11. In this way, the erosion of the side wall of the second sub-portion 152 by the process solution in the display panel 10 process can be effectively reduced, thereby reducing the risk of packaging failure caused by the erosion of the second sub-portion 152, reducing the probability of corrosion of the second sub-portion 152, and improving the reliability and display effect of the display panel 10.
[0165] See also Figures 3 to 6 In some embodiments, the fourth protection portion 181 also covers the surface of the second sub-portion 152 facing away from the substrate 11 .
[0166] Therefore, the corrosion of the second sub-portion 152 by the process solution in the manufacturing process of the display panel 10 can be greatly reduced, the risk of packaging failure caused by the corrosion of the second sub-portion 152 can be effectively reduced, and the reliability and display effect of the display panel 10 can be improved.
[0167] See also Figures 3 to 6 In some embodiments, the first protecting portion 1621 covers the fourth protecting portion 181 .
[0168] Therefore, the first protection portion 1621 and the fourth protection portion 181 can effectively protect the second sub-portion 152, greatly reducing the corrosion of the second sub-portion 152 by the process solution in the display panel 10 process, effectively reducing the risk of packaging failure caused by the corrosion of the second sub-portion 152, and improving the reliability and display effect of the display panel 10.
[0169] See also Figure 3 In some embodiments, the display panel 10 further includes a fifth protecting portion 182 connected to the fourth protecting portion 181 , the fifth protecting portion 182 covers the second sub-layer 1712 and the second sub-segment 1512 ; the second protecting portion 1622 and the third protecting portion 1623 are both located on the side of the fifth protecting portion 182 away from the substrate 11 .
[0170] Thus, a multi-layer protection can be formed for the first sub-portion 151, which can greatly reduce the corrosion of the first sub-portion 151 by the process solution in the display panel 10 process, thereby reducing the risk of packaging failure caused by the corrosion of the first sub-portion 151, reducing the probability of corrosion of the first sub-portion 151, and improving the reliability and display effect of the display panel 10.
[0171] In some embodiments, the fourth protection portion 181 and the fifth protection portion 182 are made of inorganic materials. In a specific example, the fourth protection portion 181 and the fifth protection portion 182 are made of silicon oxide or silicon nitride.
[0172] Therefore, the fourth protection portion 181 and the fifth protection portion 182 can isolate water vapor and oxygen, thereby improving the packaging reliability of the display panel 10 .
[0173] In one embodiment, the first trace 15 includes at least one metal layer.
[0174] See also Figures 4 to 6 In one embodiment, the first trace 15 includes a first metal layer 15a, a second metal layer 15b and a third metal layer 15c stacked in sequence in a direction away from the substrate 11; the fourth protection portion 181 at least covers the side wall of the second metal layer 15b of the second sub-portion 152; specifically, the material of the first metal layer 15a and the third metal layer 15c may be titanium, and the material of the second metal layer 15b may be aluminum.
[0175] Therefore, by making the fourth protection portion 181 at least cover the side wall of the second metal layer 15b of the second sub-portion 152; and the first protection portion 1621 covers the fourth protection portion 181, in this way, at least double-layer protection can be formed on the side wall of the second metal layer 15b of the second sub-portion 152, thereby reducing the corrosion of the second metal layer 15b of the second sub-portion 152 by the process solution in the display panel 10 process, effectively reducing the risk of packaging failure caused by the corrosion of the first wiring 15, and greatly improving the reliability and display effect of the display panel 10.
[0176] See also Figures 5 and 6 In one embodiment, the orthographic projection of the second metal layer 15b on the substrate 11 is located within the orthographic projection of the first metal layer 15a on the substrate 11; the orthographic projection of the second metal layer 15b on the substrate 11 is located within the orthographic projection of the third metal layer 15c on the substrate 11. Specifically, the material of the first metal layer 15a and the third metal layer 15c can be titanium, and the material of the second metal layer 15b can be aluminum.
[0177] That is to say, the second wiring 205 has an I-shaped structure. By making the fourth protection portion 181 cover at least the side wall of the second metal layer 15b of the second sub-portion 152, and the first protection portion 1621 covers the fourth protection portion 181, at least double-layer protection can be formed on the side wall of the second metal layer 15b of the second sub-portion 152, thereby reducing the probability of packaging failure at the side wall position of the second sub-portion 152 and improving the reliability of the display panel 10.
[0178] See also Figures 5 and 6 In some embodiments, the fourth protection portion 181 covers a surface of the first metal layer 15 a of the second sub-portion 152 facing away from the substrate 11 and a side wall of the first metal layer 15 a of the second sub-portion 152 .
[0179] Therefore, the probability of packaging failure occurring at the side wall of the second sub-portion 152 can be further reduced, thereby improving the reliability of the display panel 10 .
[0180] See also Figures 5 and 6 In some embodiments, the fourth protection portion 181 also covers a surface of the third metal layer 15 c of the second sub-portion 152 close to the substrate 11 and a side wall of the third metal layer 15 c of the second sub-portion 152 .
[0181] Therefore, the probability of packaging failure occurring at the sidewall of the second sub-portion 152 can be further reduced, thereby improving the reliability of the display panel 10 .
[0182] See also Figure 5 and Figure 6 In some embodiments, a side wall of the first trace 15 is provided with a concave structure, and the fourth protection portion 181 covers the concave structure on the second sub-portion 152 .
[0183] Therefore, by making the fourth protective portion 181 cover the concave structure on the second sub-portion 152, and the first protective portion 1621 covering the fourth protective portion 181, at least double-layer protection can be formed for the concave structure on the second sub-portion 152, thereby reducing the probability of packaging failure of the concave structure on the second sub-portion 152 and improving the reliability of the display panel 10.
[0184] See also Figure 3 In one embodiment, it also includes a packaging structure 19, which is arranged on the side of the light-emitting functional portion 13 away from the substrate 11; the packaging structure 19 includes an organic packaging layer 192, which is arranged on the side of the dam structure 17 close to the display area 10a.
[0185] Therefore, by providing the encapsulation structure 19, the probability of failure or performance degradation of the light-emitting functional part 13 in the display panel 10 due to corrosion by external water vapor and oxygen can be reduced. The organic encapsulation layer 192 of the encapsulation structure 19 usually has a certain fluidity. By providing the dam structure 17, the organic encapsulation layer 192 is arranged on the side of the dam structure 17 close to the display area 10a, that is, the organic encapsulation layer 192 of the encapsulation structure 19 is blocked by the dam structure 17. In this way, the organic encapsulation layer 192 can be prevented from overflowing to an undesirable area, and water vapor can be blocked from invading the display area 10a, thereby improving the encapsulation reliability of the encapsulation structure 19, and further improving the reliability of the display panel 10.
[0186] See also Figure 2 , Figures 8 to 10 In some embodiments, the encapsulation structure 19 further includes a plurality of first sub-encapsulation parts 191; the plurality of first sub-encapsulation parts 191 are correspondingly disposed on a side of the plurality of light-emitting functional parts 13 away from the substrate 11; the first sub-encapsulation parts 191 cover a side of the light-emitting functional parts 13 away from the substrate 11 and at least a portion of a side wall of the isolation structure 12 close to the first opening 12a1; the organic encapsulation layer 192 covers the plurality of first sub-encapsulation parts 191 and the first insulating layer 161;
[0187] Therefore, by setting multiple first sub-packaging parts 191, separate packaging of multiple light-emitting functional parts 13 can be achieved, which can effectively prevent external water vapor from diffusing toward the light-emitting functional part 13, and effectively prevent external defects from expanding toward the light-emitting functional part 13, thereby improving packaging reliability.
[0188] See also Figures 8 to 10 In some embodiments, the first sub-encapsulation portion 191 extends to a side of the isolation structure 12 facing away from the substrate 11 .
[0189] In addition, the direct contact area between the organic encapsulation layer 192 and the isolation structure 12 can be reduced, thereby reducing the risk of peeling of the organic encapsulation layer 192 , improving the encapsulation reliability of the organic encapsulation layer 192 , and further improving the encapsulation reliability of the encapsulation structure 19 .
[0190] See also Figure 3 , Figure 6 , Figures 8 to 10 In some embodiments, the encapsulation structure 19 further includes a second encapsulation layer 193 , and the second encapsulation layer 193 covers at least a portion of the organic encapsulation layer 192 and the first protection layer 162 .
[0191] Thus, the first sub-encapsulation portion 191, the organic encapsulation layer 192, and the second encapsulation layer 193 form a three-layer encapsulation, which can improve the encapsulation reliability of the encapsulation structure 19. In addition, the second encapsulation layer 193 covers at least part of the organic encapsulation layer 192 and the first protective layer 162, so that the second encapsulation layer 193 and the first protective layer 162 can protect the first wiring 15, thereby reducing the risk of encapsulation failure caused by corrosion of the first wiring 15, thereby improving the reliability and display effect of the display panel 10.
[0192] See also Figure 3 In some embodiments, the boundary of the second encapsulation layer 193 is located on a side of the dam structure 17 away from the display area 10 a.
[0193] As a result, the packaging reliability of the side of the dam structure 17 away from the display area 10 a is improved, the probability of moisture intruding into the display area 10 a is reduced, and the reliability of the display panel 10 is improved.
[0194] In some embodiments, there is a first spacing between the boundary of the second encapsulation layer 193 and the side of the dam structure 17 away from the display area 10a, and the first spacing is 100um to 400um. Specifically, the first spacing can be 100um, 150um, 200um, 250um, 300um, 350um, or 400um.
[0195] In some embodiments, the first sub-encapsulation portion 191 is an inorganic encapsulation layer.
[0196] Therefore, the first sub-packaging portion 191 can isolate water vapor and oxygen, thereby improving the packaging reliability of the display panel 10 .
[0197] In some embodiments, the second encapsulation layer 193 is an inorganic encapsulation layer.
[0198] Therefore, the second encapsulation layer 193 can isolate water vapor and oxygen, thereby improving the encapsulation reliability of the display panel 10 .
[0199] See also Figure 2 , Figure 7, Figures 8 to 10 In one embodiment, the display panel 10 further includes a first electrode 201 . The first electrode 201 is located on a side of the substrate 11 close to the isolation structure 12 . The first electrode 201 is electrically insulated from the isolation structure 12 .
[0200] See also Figure 2 , Figure 7 , Figures 8 to 10 In some embodiments, the display panel 10 further includes a second insulating layer 202, the second insulating layer 202 is located between the first electrode 201 and the isolation structure 12, a second opening 202a is provided on the second insulating layer 202, and the second opening 202a corresponds to the first opening 12a1; at least a portion of the light-emitting functional portion 13 is provided in the second opening 202a, and the second opening 202a exposes the first electrode 201.
[0201] Thus, by providing the second insulating layer 202 , the first electrode 201 and the isolation structure 12 as well as adjacent first electrodes 201 can be insulated from each other.
[0202] In a specific example, the second insulating layer 202 may be a pixel definition layer PDL, and the second opening 202 a is a pixel opening.
[0203] In another specific example, the second insulating layer 202 may also be other insulating film layers.
[0204] In another specific example, the material of the second insulating layer 202 includes an inorganic material, such as silicon oxide, silicon nitride, etc.
[0205] Therefore, the second insulating layer 202 can isolate water vapor and oxygen, thereby improving the reliability of the display panel 10 .
[0206] In another specific example, the material of the second insulating layer 202 includes an organic material, such as an organic glue.
[0207] Therefore, the production of the second insulating layer 202 can be facilitated, and the thickness of the second insulating layer 202 can be larger, thereby reducing the interference between the isolation structure 12 and the wiring in the substrate 11 and between the first touch part 141 and the wiring in the substrate 11 when transmitting signals, thereby improving the display effect and touch effect of the display panel 10.
[0208] In some embodiments, the second insulating layer 202 , the fourth protection portion 181 and the fifth protection portion 182 are disposed in the same layer.
[0209] Therefore, the second insulating layer 202, the fourth protective part 181 and the second protective layer of the fifth protective part 182 can be obtained by patterning the same film layer, thereby reducing the use of mask plates and saving mask processes, thereby improving the production efficiency of the display panel 10, reducing production costs, and facilitating the thinning of the display panel 10.
[0210] In some embodiments, the first trace 15 is located on a side of the first electrode 201 close to the substrate 11 .
[0211] See also Figures 8 to 10 In some embodiments, the orthographic projection of the isolation structure 12 on the substrate is located at the periphery of the orthographic projection of the second opening 202a on the substrate.
[0212] Thus, it is possible to avoid the isolation structure 12 limiting the light emission angle of the light emitting functional part 13 .
[0213] See also Figure 2 , Figure 7 , Figures 8 to 10 In some embodiments, the display panel 10 further includes a second electrode 203 . The second electrode 203 is located on a side of the light emitting functional portion 13 away from the substrate 11 . The second electrode 203 is electrically connected to the isolation structure 12 .
[0214] Therefore, by electrically connecting the second electrode 203 to the isolation structure 12 , the isolation structure 12 is equivalent to having the function of transmitting power signals, thereby reducing the wiring of the display area 10 a of the display panel 10 .
[0215] It should be noted that the first electrode 201, the light emitting functional unit 13 and the second electrode 203 together constitute a light emitting unit. The first electrode 201 may be an anode, and the second electrode 203 may be a cathode. The first electrode 201 and the second electrode 203 are both electrically connected to the pixel driving circuit.
[0216] See also Figure 2 , Figure 7 , Figures 8 to 10 In one embodiment, the first touch portion 141 and the isolation structure 12 are disposed in the same layer and arranged at intervals.
[0217] Thus, the first touch portion 141 and the isolation structure 12 can be obtained by patterning the same film layer, thereby reducing the use of mask plates and saving mask processes, which is beneficial to improving the production efficiency of the display panel 10, reducing the production cost of the display panel 10, and facilitating the thinning of the display panel 10.
[0218] See also Figure 2 , Figure 7 , Figures 8 to 10In some embodiments, the isolation structure 12 includes a plurality of sub-isolation structures 12a arranged at intervals, each sub-isolation structure 12a defines at least one first opening 12a1; an isolation gap 12b is provided between adjacent sub-isolation structures 12a; and the sub-isolation structure 12a is spaced apart from the first touch portion 141.
[0219] See also Figure 2 , Figure 7 , Figures 8 to 10 In some embodiments, the sub-isolation structure 12a includes an isolation body 121 and a blocking portion 122, wherein the blocking portion 122 is located on a side of the isolation body 121 facing away from the substrate 11, and the orthographic projection of the isolation body 121 on the substrate 11 is located within the orthographic projection of the blocking portion 122 on the substrate 11.
[0220] In this way, the sub-isolation structure 12a can form an undercut structure with a "large top and small bottom", and the sub-isolation structure 12a corresponding to the first opening 12a1 can have a "roof", so that the adjacent light-emitting functional parts 13 can be separated during the evaporation process, thereby avoiding crosstalk between light-emitting functional parts 13 of different colors, thereby improving the display effect of the display panel 10.
[0221] In some embodiments, the light-emitting functional portion 13 includes a plurality of functional layers, and at least some of the functional layers are spaced apart from the separator 121 .
[0222] In this way, it can be ensured that the film layers of the light-emitting functional parts 13 of different colors are insulated from each other, thereby avoiding the problem of current crosstalk between the light-emitting functional parts 13 of different colors, and ensuring that when the light-emitting functional parts 13 of the corresponding color are lit, the current will not be transmitted laterally to the adjacent light-emitting functional parts 13, thereby preventing the display panel 10 from having color crosstalk, improving the display effect of the display panel 10, and enhancing the display quality of the display panel 10.
[0223] In some of the embodiments, the orthographic projection of the sub-isolation structure 12a on the substrate 11 is in the shape of a grid;
[0224] Thus, the uniformity of the orthographic projection area of the sub-isolation structure 12 a on the substrate can be improved, thereby reducing the difficulty of manufacturing the isolation structure 12 .
[0225] In some embodiments, the orthographic projection of the sub-isolation structure 12a on the substrate 11 is a closed ring; that is, the sub-isolation structure 12a is a ring structure. Exemplarily, the sub-isolation structure 12a can be rectangular ring-shaped, circular ring-shaped, triangular ring-shaped, etc.
[0226] Thus, the isolation effect of the sub-isolation structure 12 a on the evaporated material can be ensured, and the connection of the evaporated materials of adjacent light-emitting functional parts 13 can be avoided, thereby avoiding crosstalk between adjacent light-emitting functional parts 13 , thereby improving the display effect of the display panel 10 .
[0227] In some embodiments, the material of the isolator 121 includes a conductive material.
[0228] In a specific example, the separator 121 includes at least one metal layer.
[0229] In one example, the material of the metal layer includes at least one of a metal and a metal oxide. For example, the metal may be silver, copper, titanium, aluminum, etc. The metal oxide may be tin oxide, zinc oxide, cadmium oxide, indium oxide, indium tin oxide, zinc indium oxide, zinc gallium oxide, zinc aluminum oxide, titanium tantalum oxide, etc.
[0230] In some embodiments, the material of the barrier 122 includes a conductive material. In one example, the barrier 122 may be a metal structure, that is, the material of the barrier 122 is metal, for example, the barrier 122 may be a conductive metal material such as silver, copper, titanium, aluminum, etc.
[0231] Thus, on the one hand, the strength and hardness of the barrier 122 can be improved, so that the barrier 122 is not easy to collapse during the partition structure molding process, and the projection relationship between the barrier 122 and the isolator 121 on the substrate 11 is ensured, which is conducive to obtaining a partition structure of a desired shape. On the other hand, the barrier 122 and the isolator 121 can form a multi-layer metal layer stacked, which can reduce the resistance of the isolation structure 12, thereby reducing the power consumption of the display panel 10.
[0232] In some embodiments, the material of the blocking portion 122 includes an insulating material. For example, the material of the blocking portion 122 may be an inorganic material, such as silicon nitride, silicon oxide, and the like.
[0233] Therefore, when a conductive film layer is provided on the side of the isolation structure 12 facing away from the substrate 11, the isolation structure 12 can utilize its own blocking portion 122 to be electrically insulated from the conductive film layer without the need to separately provide an insulating film layer to achieve electrical insulation, thereby facilitating a reduction in the thickness of the display panel 10.
[0234] See also Figure 2 In one embodiment, the first insulating layer 161 also covers at least a portion of the sidewall of the isolation structure 12 close to the first touch portion 141 .
[0235] Therefore, the first insulating layer 161 can protect the side of the isolation structure 12 close to the first touch portion 141 , thereby improving the reliability of the display panel 10 .
[0236] See also Figures 7 to 10In some embodiments, the first insulating layer 161 extends to a side of the isolation structure 12 close to the first touch portion 141 facing away from the substrate 11 .
[0237] Thus, the first insulating layer 161 can protect the sidewall of the isolation structure 12 close to the first touch portion 141 and the side away from the substrate 11 , thereby improving the reliability of the display panel 10 .
[0238] In some embodiments, the first insulating layer 161 is made of inorganic material.
[0239] Therefore, the first insulating layer 161 can isolate water vapor and oxygen, thereby improving the packaging reliability of the display panel 10 .
[0240] See also Fig.11 In one embodiment, the first touch portion 141 includes a plurality of sub-touch electrodes 1411 ; the plurality of sub-touch electrodes 1411 are disposed at intervals in the isolation gap 12 b.
[0241] In this way, only one touch film layer (ie, the first touch portion 141 ) may be provided in the display panel 10 to enable the display panel 10 to have a touch function, thereby reducing the thickness of the display panel 10 .
[0242] It should be noted that, in the embodiment of the present application, each sub-touch electrode 1411 is both a driving electrode and a receiving electrode, and the sub-touch electrode 1411 can realize the touch function through the self-capacitance principle with the assistance of other metal film layers on the display panel 10.
[0243] See also Fig.12 In some embodiments, each sub-touch electrode 1411 is disposed around at least a portion of the periphery of at least one sub-isolation structure 12 a.
[0244] Thus, the area of the sub-touch electrode 1411 can be increased, thereby improving the touch accuracy.
[0245] See also Fig.11 In some embodiments, the plurality of touch sub-electrodes 1411 are arranged in rows along a first direction X and in columns along a second direction Y intersecting the first direction X.
[0246] Thus, the sub-touch electrodes 1411 can be distributed more evenly, so that the touch accuracy of the display panel 10 is higher.
[0247] See also Fig.12 In some embodiments, the sub-touch electrode 1411 includes a plurality of sub-electrode units 1411a that are spaced apart.
[0248] Thus, the area of the sub-touch electrode 141 can be maximized, thereby improving the touch accuracy.
[0249] See also Fig. 9 , Fig.10 , Fig.13 and Fig.14 In one embodiment, the display panel 10 further includes a second touch portion 142; one of the first touch portion 141 and the second touch portion 142 is configured as a transmitting electrode, and the other is configured as a receiving electrode.
[0250] Thus, the touch precision and accuracy of the display panel 10 can be improved.
[0251] See also Fig.14 In some embodiments, the second touch portion 142 is disposed in the isolation gap 12b, and the second touch portion 142 is spaced apart from the isolation structure 12 and the first touch portion 141. That is, the first touch portion 141 and the second touch portion 142 may be disposed in the same layer.
[0252] Therefore, the thickness of the display panel 10 can be reduced while the touch precision and accuracy of the display panel 10 can be improved.
[0253] See also Fig. 9 , Fig.10 In some embodiments, the second touch portion 142 is located on a side of the first insulating layer 161 facing away from the substrate 11 .
[0254] In this way, by providing two touch film layers (ie, the first touch portion 141 and the second touch portion 142 ), the touch precision and accuracy of the display panel 10 can be improved.
[0255] See also Fig.13 In some embodiments, the first touch portion 141 includes a plurality of first sub-electrodes 1412; the plurality of first sub-electrodes 1412 extend along the second direction Y and are spaced apart along the first direction X; the second touch portion 142 includes a plurality of second sub-electrodes 1421; the plurality of second sub-electrodes 1421 extend along the first direction X and are spaced apart along the second direction Y; the first direction X and the second direction Y intersect.
[0256] Thus, the coupling area between the first sub-electrode 1412 and the second sub-electrode 1421 can be increased, and the change amount of the capacitance signal when a finger touches can be effectively increased, thereby effectively improving the touch sensitivity.
[0257] See also Figures 8 to 10 , Fig.12 , Fig.14 In one embodiment, the display panel 10 further includes a conductive connecting portion 204 , and the conductive connecting portion 204 connects adjacent sub-isolation structures 12 a .
[0258] Thus, a plurality of sub-isolation structures 12 a arranged at intervals can be connected into one piece, thereby reducing resistance, which is beneficial to reducing power consumption of the display panel 10 .
[0259] See also Fig.12 In one embodiment, the conductive connection portion 204 is located in the isolation gap 12 b , and the conductive connection portion 204 and the sub-isolation structure 12 a are disposed in the same layer and arranged at intervals.
[0260] Therefore, when manufacturing the isolation structure 12, the conductive connection part 204 can be manufactured simultaneously, thereby reducing the use of mask plates and saving mask processes, which is beneficial to improving the manufacturing efficiency of the display panel 10, reducing the manufacturing cost of the display panel 10, and facilitating the thinning of the display panel 10.
[0261] See also Figures 8 to 10 , Fig.14 In one embodiment, the conductive connection portion 204 is located on a side of the substrate 11 close to the isolation structure 12 .
[0262] See also Figure 8 , Fig. 9 In a specific example, the conductive connection portion 204 can be disposed in the same layer as the first electrode 201 and arranged at intervals.
[0263] See also Fig.10 In another specific example, the conductive connection portion 204 can be disposed in the same layer as the first trace 15 and arranged at intervals.
[0264] In one embodiment, the first wiring 15 is electrically connected to the isolation structure 12. The first wiring 15 can be used for transmission of driving signals, thereby ensuring the normal operation of the display function of the display panel 10.
[0265] See also Figure 1 , Figure 3 , Fig.15 In one embodiment, the display panel 10 further includes a binding area 10c, which is located on a side of the first non-display area 10b away from the display area 10a; the binding area 10c is provided with a binding structure (not shown); the display panel 10 further includes a second wiring 205, which is electrically connected to the first wiring 15 and the binding structure.
[0266] Therefore, by providing the second wiring 205 , the second wiring 205 is electrically connected to the first wiring 15 and the binding structure, so as to facilitate the connection between the first wiring 15 and the binding structure, thereby ensuring the normal operation of the display function of the display panel 10 .
[0267] See also Figure 1 , Fig.15In some embodiments, the display panel 10 also includes a second non-display area 10d, and the second wiring area 10d is located between the first non-display area 10b and the binding area 10c; the second wiring 205 is at least partially located in the second non-display area 10d; the display panel 10 also includes a third protective layer 206; the third protective layer 206 covers the second wiring 205.
[0268] Therefore, the third protection layer 206 can provide protection for the second wiring 205 , reduce the probability of metal corrosion of the second wiring 205 , and improve the reliability of the display panel 10 .
[0269] See also Figure 1 , Figure 3 In some embodiments, the display panel 10 further includes a bending area 10e, and the bending area 10e is located between the first non-display area 10b and the second non-display area 10d; the second wiring 205 passes through the bending area 10e and is connected to the first wiring 15.
[0270] See also Figure 3 In some embodiments, the second wiring 205 and the first wiring 15 are arranged on the same layer and are interconnected.

[0272] Therefore, the third sublayer 2061 and the second insulating layer 202 can be produced simultaneously, and the fourth sublayer 2062 and the first insulating layer 161 can be produced simultaneously, thereby reducing the use of mask plates and saving mask processes, which is beneficial to improving the production efficiency of the display panel 10, reducing the production cost of the display panel 10, and facilitating the thinning of the display panel 10.

The polarizer 207 is disposed on a side of the first insulating layer 161 away from the substrate 11, and the orthographic projection of the polarizer 207 in the first non-display area 10b is located within the orthographic projection of the first protective layer 162 in the first non-display area 10b.
[0274] The polarizer 207 contains harmful elements. In a high temperature and high humidity environment, the harmful elements of the polarizer will diffuse to the first wiring 15. By making the orthographic projection of the polarizer 207 in the first non-display area 10b be located within the orthographic projection of the first protective layer 162 in the first non-display area 10b, the erosion of the side wall of the first wiring 15 by the process solution in the display panel manufacturing process can be reduced, and the risk of packaging failure caused by the erosion of the first wiring 15 can be reduced, thereby reducing the probability of the harmful elements in the polarizer 207 diffusing to the first wiring 15, and further reducing the probability of the first wiring 15 being corroded, thereby reducing the probability of the display panel 10 having a poor display, improving the display effect and reliability of the display panel 10, and further improving the display effect and reliability of the display device 1. In addition, by providing the polarizer 207, the display effect of the display panel 10 can be improved.

In this way, on the one hand, the corrosion of the side wall of the first wiring 15 by the process solution in the display panel process can be weakened, and the risk of packaging failure caused by the corrosion of the first wiring 15 can be reduced, thereby improving the reliability and display effect of the display panel 10; on the other hand, the interference between the electric field generated by the isolation structure 12 when transmitting the signal and the electric field generated by the first touch part 141 can be reduced, thereby improving the display effect and touch effect of the display panel 10; in addition, the first insulating layer 161 and the first protective layer 162 are obtained by patterning the first insulating film layer. In this way, the use of the mask plate can be reduced, the mask process can be saved, and the number of film layers of the display panel 10 can be reduced, thereby improving the production efficiency of the display panel 10, reducing the production cost of the display panel 10, and facilitating the thinning of the display panel 10.
