[0016] It should be noted that different features in the embodiments of the present application may be combined with each other unless they are inconsistent.

[0017] 1 , a display panel in the related art includes an array substrate 1, an isolation structure 7 located on one side of the array substrate 1, a light-emitting unit 8 at least partially located within an isolation opening 6 defined by the isolation structure 7, and a first encapsulating layer 9 located on the side of the light-emitting unit 8 away from the array substrate 1. The light-emitting unit 8 includes a first light-emitting unit and a second light-emitting unit. According to the manufacturing sequence of the first light-emitting unit and the second light-emitting unit, after the first light-emitting unit is formed, a portion of the first encapsulating layer 9 remains on the side wall of the isolation structure 7 corresponding to the second light-emitting unit. After the second light-emitting unit is formed, the second electrode 5 of the second light-emitting unit does not effectively overlap the side wall of the isolation structure 7 corresponding to the second light-emitting unit, which affects the display effect of the display panel.

[0018] In view of this, this embodiment provides a technical form that can improve the display effect of the display panel, and the technical form according to this embodiment will be described in detail below.

[0019] As shown in FIG. 2, this embodiment provides a display panel, which includes an array substrate 1, an isolation structure 7, a light-emitting unit 8, and a first encapsulation layer 9.

[0020] The array substrate 1 may include a substrate and a plurality of driving units located on one side of the substrate, and each driving unit may include one or more semiconductor switching elements. The semiconductor switching elements may be formed by combining multiple film layers of the array substrate 1, for example, thin film transistors formed by combining multiple film layers.

[0021] The isolation structure 7 is located on one side of the array substrate 1 and defines an isolation opening 6 .

[0022] The configuration, manufacture, etc. of the isolation structure 7 are further described in International Patent Application PCT / CN2023 / 134518, Chinese Patent Application No. 202310759370.2, Chinese Patent Application No. 202310740412.8, Chinese Patent Application No. 202310707209.0, Chinese Patent Application No. 202311346196.5, Chinese Patent Application No. 202311499823.9, Chinese Patent Application No. 202310731471.9, and Chinese Patent Application No. 202311091555.7 for reference.

[0023] At least a portion of the light-emitting unit 8 is located within the isolation opening 6, and the light-emitting unit 8 includes a first light-emitting unit and a second light-emitting unit. The first light-emitting unit and the second light-emitting unit emit light of different colors, for example, the first light-emitting unit may be red and the second light-emitting unit may be green.

[0024] The first sealing layer 9 is located on the side of the light-emitting unit 8 away from the array substrate 1, and includes a plurality of sealing units 91 spaced apart. The sealing units 91 extend from the side of the isolation structure 7 to the side of the isolation structure 7 away from the array substrate 1, and the side of the isolation structure 7 faces the isolation opening 6. In the portion of the sealing unit 91 on the side of the isolation structure 7 away from the array substrate 1, the side close to the isolation structure 7 and the side away from the isolation opening 6 form a tapered angle. The tapered angle β1 of the sealing unit 91 corresponding to the first light-emitting unit and the tapered angle β2 of the sealing unit 91 corresponding to the second light-emitting unit are not equal.

[0025] According to the manufacturing sequence of the first light-emitting unit and the second light-emitting unit, after manufacturing the first light-emitting unit, the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the second light-emitting unit is etched by a side etching method, and when the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the second light-emitting unit is removed by etching, the portion of the sealing unit 91 corresponding to the first light-emitting unit on the side away from the array substrate 1 of the isolation structure 7 is side-etched.

[0026] In this embodiment, because no other light-emitting units 8 are manufactured after the second light-emitting unit, after manufacturing the second light-emitting unit, there is no need to side-etch the portion of the sealing unit 91 corresponding to the second light-emitting unit on the side of the isolation structure 7 away from the array substrate 1. Therefore, in the sealing unit 91 corresponding to the first light-emitting unit, in the portion of the isolation structure 7 away from the array substrate 1, the taper angle β1 formed between the side close to the isolation structure 7 and the side away from the isolating opening 6 is not equal to the taper angle β2 formed between the side close to the isolation structure 7 and the side away from the isolating opening 6 on the side of the isolation structure 7 away from the array substrate 1 in the sealing unit 91 corresponding to the second light-emitting unit.

[0027] Before manufacturing the second light-emitting unit, the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the second light-emitting unit is removed by etching, so that the second electrode 5 of the second light-emitting unit can effectively overlap the corresponding isolation structure 7, thereby improving the display effect of the second light-emitting unit and the display effect of the display panel.

[0028] According to the above design, in this embodiment, the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the second light-emitting unit is side-etched, so that the taper angle β1 of the sealing unit 91 corresponding to the first light-emitting unit and the taper angle β2 of the sealing unit 91 corresponding to the second light-emitting unit are not equal. Finally, the second electrodes 5 of the first light-emitting unit and the second light-emitting unit can both effectively overlap the corresponding isolation structure 7, thereby improving the display effect of the display panel.

[0029] In some possible embodiments, as shown in FIG. 3, the display panel further includes a third light-emitting unit, and the taper angle of the sealing unit 91 corresponding to the third light-emitting unit is not equal to the taper angle of the sealing units 91 corresponding to the first and second light-emitting units.

[0030] The first light-emitting unit, the second light-emitting unit, and the third light-emitting unit each emit light of a different color. For example, the first light-emitting unit may be red, the second light-emitting unit may be green, and the third light-emitting unit may be blue.

[0031] After manufacturing the first light-emitting unit according to the manufacturing order of the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit, the first sealing layer 9 remaining on the side walls of the isolation structure 7 corresponding to the second light-emitting unit and the third light-emitting unit is etched by a side etching method, and when the first sealing layer 9 remaining on the side walls of the isolation structure 7 corresponding to the second light-emitting unit and the third light-emitting unit is removed by etching, the portion of the sealing unit 91 corresponding to the first light-emitting unit that is away from the array substrate 1 of the isolation structure 7 is side-etched.

[0032] After manufacturing the second light-emitting unit, the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the third light-emitting unit is etched by a side etching method, and when the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the third light-emitting unit is removed by etching, the portion of the sealing unit 91 corresponding to the second light-emitting unit that is away from the array substrate 1 of the isolation structure 7 is side-etched.

[0033] In this embodiment, because no other light-emitting units 8 are manufactured after the third light-emitting unit, it is not necessary to perform side etching on the portion of the isolation structure 7 away from the array substrate 1 in the sealing unit 91 corresponding to the third light-emitting unit after manufacturing the third light-emitting unit. Therefore, the taper angle β1 formed between the side close to the isolation structure 7 and the side away from the isolating opening 6 in the portion of the isolation structure 7 away from the array substrate 1 in the sealing unit 91 corresponding to the first light-emitting unit, the taper angle β2 formed between the side close to the isolation structure 7 and the side away from the isolating opening 6 in the portion of the isolation structure 7 away from the array substrate 1 in the sealing unit 91 corresponding to the second light-emitting unit, and the taper angle β3 formed between the side close to the isolation structure 7 and the side away from the isolating opening 6 in the portion of the isolation structure 7 away from the array substrate 1 in the sealing unit 91 corresponding to the third light-emitting unit are all unequal.

[0034] Before the second light-emitting unit is manufactured, the first sealing layer 9 remaining on the sidewall of the isolation structure 7 corresponding to the second light-emitting unit is removed by etching, so that the second electrode 5 of the second light-emitting unit can effectively overlap the corresponding isolation structure 7. Before the third light-emitting unit is manufactured, the first sealing layer 9 remaining on the sidewall of the isolation structure 7 corresponding to the third light-emitting unit is removed by etching, so that the second electrode 5 of the third light-emitting unit can effectively overlap the corresponding isolation structure 7, thereby improving the display effect of the second light-emitting unit and the third light-emitting unit, and thereby improving the display effect of the display panel.

[0035] 3 , in some possible embodiments, the taper angle β1 of the sealing unit 91 corresponding to the first light-emitting unit is in the range of 30° to 60°, for example, the taper angle β1 may be 30°, 35°, 45°, 50°, 55°, 60°, etc. By rationally setting the taper angle β1, the first sealing unit 91 remaining on the sidewall of the isolation structure 7 corresponding to the second light-emitting unit can be more neatly etched, thereby more effectively overlapping the second electrode 5 of the second light-emitting unit with the corresponding isolation structure 7.

[0036] 3 , in some possible embodiments, the taper angle β2 of the sealing unit 91 corresponding to the second light-emitting unit is in the range of 30° to 80°, for example, the taper angle β2 may be 30°, 35°, 45°, 55°, 65°, 75°, 80°, etc. By rationally setting the taper angle β2, the first sealing unit 91 remaining on the sidewall of the isolation structure 7 corresponding to the third light-emitting unit can be more neatly etched, thereby more effectively overlapping the second electrode 5 of the third light-emitting unit with the corresponding isolation structure 7.

[0037] 3 again, the taper angle β3 of the sealing unit 91 corresponding to the third light-emitting unit is preferably in the range of 80° to 90°, and may be, for example, 80°, 82°, 85°, 88°, or 90°. By rationally setting the taper angle β3 after manufacturing the third light-emitting unit, the step of side-etching the first sealing layer corresponding to the third light-emitting unit can be omitted, thereby reducing the manufacturing cost of the display panel.

[0038] In this embodiment, since no other light-emitting units 8 are typically manufactured after the third light-emitting unit, it may not be necessary to side-etch the portion of the sealing unit 91 corresponding to the third light-emitting unit that is away from the array substrate 1 of the isolation structure 7 after the third light-emitting unit is manufactured. Therefore, the theoretical taper angle β3 of the sealing unit 91 corresponding to the third light-emitting unit is 90°. Because some error may occur in the manufacturing process, the taper angle β3 of the sealing unit 91 corresponding to the third light-emitting unit may be in the range of 80° to 90°.

[0039] 3, adjacent sealing units 91 are spaced apart on the side of the isolation structure 7 facing away from the array substrate 1. There is a gap between the part of the sealing unit 91 facing away from the array substrate 1 of the isolation structure 7 and the side of the isolation structure 7 facing away from the array substrate 1. The material of the first sealing layer 9 includes an inorganic material.

[0040] When manufacturing the first sealing layer 9, the first sealing layer 9 is cut at the isolation structures 7 to form a plurality of sealing units 91 spaced apart, which can independently seal the light-emitting units 8, thereby improving the display characteristics of the display panel.

[0041] 3 , in some possible embodiments, the light-emitting unit 8 includes a first electrode layer, a light-emitting functional layer, and a second electrode layer that are stacked in this order along a direction away from the array substrate 1, and the display panel further includes a pixel defining layer 3 located on a side of the first electrode layer that faces away from the array substrate 1, and the isolation structure 7 is located on a side of the pixel defining layer 3 that faces away from the array substrate 1. The pixel defining layer 3 includes pixel openings 31 that expose at least a portion of the first electrodes 2, and the orthogonal projections of the isolation structures 7 on the array substrate 1 are located between the orthogonal projections of two adjacent pixel openings 31 on the array substrate 1. The orthogonal projections of the pixel openings 31 on the array substrate 1 are located within the orthogonal projections of the isolation openings 6 on the array substrate 1.

[0042] When forming the light-emitting functional layer, the light-emitting functional layer is separated by isolation structures 7 to form a plurality of spaced-apart light-emitting portions 4, and when forming the second electrode layer, the second electrode layer is separated by isolation structures 7 to form a plurality of spaced-apart second electrodes 5. The isolation structures 7 include a conductive material, and the second electrodes 5 are electrically connected to the isolation structures 7, so that one light-emitting unit 8 is formed by one first electrode 2, one light-emitting portion 4, and one second electrode 5. The first electrode 2 is an anode or a cathode, and the second electrode 5 is a cathode or an anode. When the first electrode 2 is an anode, the second electrode 5 is a cathode. When the first electrode 2 is a cathode, the second electrode 5 is an anode.

[0043] In some embodiments, the pixel defining layer 3 may further comprise recesses, the isolation structures 7 being located within the recesses.

[0044] In some possible embodiments, as shown again in FIG. 3, the isolation structure 7 includes a first isolation portion 71 and a second isolation portion 72 stacked in order along a direction away from the array substrate 1, and the orthogonal projection of the first isolation portion 71 on the array substrate 1 is located within the orthogonal projection of the second isolation portion 72 on the array substrate 1.

[0045] Because the second isolation portion 72 is located on the side of the first isolation portion 71 that is farther from the array substrate 1 and the lateral width of the second isolation portion 72 is greater than the lateral width of the first isolation portion 71, the second isolation portion 72 cuts the light-emitting functional layer and the second electrode layer at the isolation structure 7. In this way, the isolation structure 7 formed by the first isolation portion 71 and the second isolation portion 72 makes it easy to seal each light-emitting unit 8 independently.

[0046] In some possible embodiments, as shown in FIG. 3 again, the second electrode 5 of the light-emitting unit 8 is electrically connected to the first isolation portion 71. As shown in FIG. 4 again, and / or the isolation structure 7 further includes a third isolation portion 73 located on the side of the first isolation portion 71 facing the array substrate 1, and the second electrode 5 of the light-emitting unit 8 is electrically connected to the third isolation portion 73. The material of the third isolation portion 73 includes a metal, such as molybdenum. And / or the material of the first isolation portion 71 includes a metal, such as aluminum. And / or the material of the second isolation portion 72 includes a metal, such as titanium. In this way, when the isolation structure 7 separates the second electrode layer into the second electrode 5, the second electrode 5 is likely to be electrically connected to the first isolation portion 71 and / or the third isolation portion 73.

[0047] In some possible embodiments, the present application further provides another display panel, which includes an array substrate 1 , an isolation structure 7 , a light-emitting unit 8 and a first encapsulation layer 9 .

[0048] The isolation structure 7 is located on one side of the array substrate 1 , and the isolation structure 7 defines an isolation opening 6 .

[0049] At least a portion of the light-emitting unit 8 is located within the isolation opening 6, and the first sealing layer 9 is located on the side of the light-emitting unit 8 away from the array substrate 1, and the first sealing layer 9 includes a plurality of sealing units 91 arranged at intervals, and the sealing units 91 extend from the side of the isolation structure 7 to the side of the isolation structure 7 away from the array substrate 1, and the side of the isolation structure 7 faces the isolation opening 6 of the isolation structure 7. In the part of the sealing unit 91 on the side away from the array substrate 1 of the isolation structure 7, the side close to the isolation structure 7 and the side away from the isolation opening 6 form a tapered angle, which is less than 90°.

[0050] During the manufacturing process of the light emitting units 8, the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the light emitting unit 8 is side-etched by a side etching method, and the remaining first sealing layer 9 is removed by etching. At the same time as removing the remaining first sealing layer 9 by etching, the portion of the sealing unit 91 corresponding to the corresponding light emitting unit 8, which is on the side of the isolation structure 7 away from the array substrate 1, is side-etched, so that the taper angle of the sealing unit 91 corresponding to the light emitting unit is smaller than 90°.

[0051] The first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the light-emitting unit 8 is removed by etching, so that the second electrode 5 of the light-emitting unit 8 can effectively overlap the corresponding isolation structure 7, thereby improving the display effect of the display panel.

[0052] In some possible embodiments, the light-emitting unit 8 includes a first light-emitting unit and a second light-emitting unit, and the taper angle β1 of the sealing unit 91 corresponding to the first light-emitting unit is in the range of 30° to 60°, for example, the taper angle β1 may be 30°, 35°, 45°, 50°, 55°, 60°, etc. The taper angle β2 of the sealing unit 91 corresponding to the second light-emitting unit is in the range of 30° to 80°, for example, the taper angle β2 may be 30°, 35°, 45°, 55°, 65°, 75°, 80°, etc. The first light-emitting unit and the second light-emitting unit emit light of different colors.

[0053] By rationally setting the taper angle β1, the first sealing unit 91 remaining on the side wall of the isolation structure 7 corresponding to the second light-emitting unit can be more neatly etched, so that the second electrode 5 of the second light-emitting unit can effectively overlap the corresponding isolation structure 7.

[0054] By rationally setting the taper angle β2, the first sealing unit 91 remaining on the side wall of the isolation structure 7 corresponding to the light-emitting unit (e.g., the third light-emitting unit) in the subsequent manufacturing process can be more neatly etched, so that the second electrode 5 of the light-emitting unit in the subsequent manufacturing process can effectively overlap the corresponding isolation structure 7.

[0055] The structure of the display panel according to this embodiment is the same as that of the display panel according to the above embodiment, and therefore will not be described here again.

[0056] In short, the present application side-etches the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the second light-emitting unit, so that the taper angle β1 of the sealing unit 91 corresponding to the first light-emitting unit and the taper angle β2 of the sealing unit 91 corresponding to the second light-emitting unit are not equal, and ultimately, the second electrodes 5 of the first light-emitting unit and the second light-emitting unit can both effectively overlap the corresponding isolation structure 7, thereby improving the display effect of the display panel.

[0057] In some possible embodiments, as shown in FIG. 5, the present application further provides a method for manufacturing a display panel, the method including the following steps:

[0058] S10: Provide an array substrate 1.

[0059] The array substrate 1 may include a substrate and a plurality of driving units located on one side of the substrate, and each driving unit may include one or more semiconductor switching elements. The semiconductor switching elements may be formed by combining multiple film layers of the array substrate 1, for example, thin film transistors formed by combining multiple film layers.

[0060] S11: On one side of the array substrate 1, an isolation structure 7 is formed, which defines an isolation opening 6.

[0061] As shown in FIG. 6, a first electrode layer is formed on one side of the array substrate 1, and the first electrode layer includes a plurality of first electrodes 2 spaced apart from one another.

[0062] 7, a pixel definition layer 3 is formed on the side of the first electrode layer away from the array substrate 1, the pixel definition layer 3 includes pixel openings 31 that expose at least a portion of the first electrode 2, and the orthogonal projections of the isolation structures 7 on the array substrate 1 are located between the orthogonal projections of two adjacent pixel openings 31 on the array substrate 1. The orthogonal projections of the pixel openings 31 on the array substrate 1 are located within the orthogonal projections of the isolation openings 6 on the array substrate 1.

[0063] As shown in FIG. 8, an isolation structure 7 is formed on the side of the pixel definition layer 3 away from the array substrate 1 .

[0064] S12: At least a portion of a light-emitting unit 8 is formed within the isolation opening 6, and a first sealing layer 9 is formed on a side of the light-emitting unit 8 facing away from the array substrate 1, the light-emitting unit 8 including a first light-emitting unit and a second light-emitting unit, the first sealing layer 9 including a plurality of sealing units 91 spaced apart, the sealing units 91 extending from the side of the isolation structure 7 to the side of the isolation structure 7 facing away from the array substrate 1, the side of the isolation structure 7 facing the isolation opening 6 of the isolation structure 7. In the portion of the sealing unit 91 facing away from the array substrate 1 of the isolation structure 7, the side close to the isolation structure 7 and the side facing away from the isolation opening 6 form tapered angles, and the tapered angle of the sealing unit 91 corresponding to the first light-emitting unit is not equal to the tapered angle of the sealing unit 91 corresponding to the second light-emitting unit.

[0065] As shown in FIG. 9, the light-emitting functional layer of the first light-emitting unit is formed on the side of the isolation structure 7 that is farther away from the array substrate 1.

[0066] The light-emitting functional layer is cut at the isolation structure 7, and at least a portion of the light-emitting functional layer is located within the isolation opening 6 to form the light-emitting portion 4. By controlling the deposition angle, the light-emitting portion 4 does not need to come into contact with the isolation structure 7.

[0067] As shown in FIG. 10, a second electrode layer is formed on the side of the light-emitting functional layer of the first light-emitting unit that is farther away from the array substrate 1.

[0068] The second electrode layer is cut at the isolation structures 7, and at least a portion of the second electrode layer is located within the isolation openings 6 to form the second electrodes 5. By controlling the deposition angle, the second electrodes 5 are extended from within the isolation openings 6 until they are in electrical contact with the isolation structures 7, thereby connecting adjacent second electrodes 5 or connecting the second electrodes 5 to other circuits. In this way, the difficulty of manufacturing the display panel can be reduced.

[0069] As shown in FIG. 11, a first sealing layer 9 is formed on the side of the second electrode layer that is farther away from the array substrate 1.

[0070] As shown in FIG. 12, a first etching protection layer 10 is formed in the isolation opening 6 corresponding to the first light-emitting unit.

[0071] The first etching protection layer 10 can protect the corresponding light-emitting functional layer of the first light-emitting unit, the second electrode layer, and the first sealing layer 9 .

[0072] As shown in FIG. 13, the first sealing layer 9, the light-emitting functional layer, and the second electrode layer that are not covered with the first etching protection layer 10 are removed along the direction perpendicular to the array substrate 1.

[0073] After removing the first sealing layer 9, the light-emitting functional layer, and the second electrode layer that are not covered by the first etching protection layer 10 along the direction perpendicular to the array substrate 1, some of the first sealing layer 9 remains on the side walls of the isolation structures 7 corresponding to the second and third light-emitting units, and the first sealing layer 9 remaining on the side walls of the isolation structures 7 corresponding to the second and third light-emitting units affects the overlap effect between the second electrodes 5 of the second and third light-emitting units and the corresponding isolation structures 7.

[0074] 14, the first sealing layer 9 on the side walls of the isolation structures 7 corresponding to the second and third light-emitting units is removed laterally, and the first etching protection layer 10 is also removed, thereby forming the light-emitting portion 4, the second electrode 5, and the sealing unit 91 in the pixel opening 31 corresponding to the first light-emitting unit, and the second electrode 5 extends until it is electrically connected to the isolation structure 7 corresponding to the first light-emitting unit. In the sealing unit 91 corresponding to the first light-emitting unit, at the side away from the array substrate 1 of the isolation structure 7, the taper angle β1 formed between the side close to the isolation structure 7 and the side away from the isolation opening 6 ranges from 30° to 60°.

[0075] After removing the first sealing layer 9, the light-emitting functional layer, and the second electrode layer that are not covered by the first etching protection layer 10, the first electrode 2, the light-emitting portion 4 of the first light-emitting unit, and the second electrode 5 form the first light-emitting unit, and the first light-emitting unit is completely covered by the sealing unit 91, thereby reducing the risk that the deposition material will be exposed to air before entering the deposition device, causing equipment contamination and cutting of the film layer.

[0076] In this way, without the need for a precise photomask, the light-emitting portion 4, the second electrode 5 and the sealing unit 91 are formed only in the pixel opening 31 corresponding to the first light-emitting unit, and the second electrode 5 may be electrically connected to the isolation structure 7, thereby forming the first light-emitting unit in the pixel opening 31 corresponding to the first light-emitting unit at a lower cost.

[0077] The first sealing layer 9 remaining on the side walls of the isolation structure 7 corresponding to the second light-emitting unit and the third light-emitting unit can be removed by side etching, and at the same time, in the sealing unit 91 corresponding to the first light-emitting unit, the taper angle β1 between the side close to the isolation structure 7 and the side away from the isolation opening 6 in the part away from the array substrate 1 of the isolation structure 7 is in the range of 30° to 60°, and for example, the taper angle β1 may be 30°, 35°, 45°, 50°, 55°, 60°, etc.

[0078] As shown in Figure 15, the light-emitting functional layer of the second light-emitting unit is formed on the side of the isolation structure 7 away from the array substrate 1, and the light-emitting functional layer of the second light-emitting unit extends to the side of the sealing unit 91 corresponding to the first light-emitting unit away from the array substrate 1.

[0079] On the basis on which the first light-emitting unit is formed, the light-emitting functional layer of the second light-emitting unit is subsequently formed, and the light-emitting functional layer of the second light-emitting unit covers the sealing unit 91 corresponding to the first light-emitting unit, and at the same time forms the light-emitting portion 4 of the second light-emitting unit within the pixel opening 31 corresponding to the second light-emitting unit.

[0080] 16, a second electrode layer is formed on the side of the light-emitting functional layer of the second light-emitting unit away from the array substrate 1. At the same time, a second electrode 5 of the second light-emitting unit is formed in the pixel opening 31 corresponding to the second light-emitting unit, and the second electrode 5 of the second light-emitting unit is electrically connected to the corresponding isolation structure 7.

[0081] As shown in FIG. 17, a first sealing layer 9 is formed on the side of the second electrode layer that is farther away from the array substrate 1.

[0082] As shown in FIG. 18, a second etching protection layer 11 is formed in the isolation opening 6 corresponding to the second light-emitting unit.

[0083] The second etching protection layer 11 can protect the corresponding light-emitting layer of the second light-emitting unit, the second electrode layer, and the first sealing layer 9 .

[0084] As shown in FIG. 19, the first sealing layer 9, the light-emitting functional layer, and the second electrode layer of the second light-emitting unit that are not covered with the second etching protection layer 11 are removed along the direction perpendicular to the array substrate 1.

[0085] After removing the first sealing layer 9, the light-emitting functional layer, and the second electrode layer that are not covered by the second etching protection layer 11 along the direction perpendicular to the array substrate 1, a portion of the first sealing layer 9 remains on the side wall of the isolation structure 7 corresponding to the third light-emitting unit, and the first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the third light-emitting unit affects the overlap effect between the second electrode 5 of the third light-emitting unit and the corresponding isolation structure 7.

[0086] 20, the first sealing layer 9 on the sidewall of the isolation structure 7 corresponding to the third light-emitting unit is removed laterally, and the second etching protection layer 11 is also removed, thereby forming the light-emitting portion 4, the second electrode 5, and the sealing unit 91 in the pixel opening 31 corresponding to the second light-emitting unit, and the second electrode 5 extends until it is electrically connected to the isolation structure 7 corresponding to the second light-emitting unit. In the sealing unit 91 corresponding to the second light-emitting unit, at the part away from the array substrate 1 of the isolation structure 7, the taper angle β2 between the side close to the isolation structure 7 and the side away from the isolation opening 6 ranges from 30° to 80°.

[0087] Before forming the second light-emitting unit, the first sealing layer 9 on the sidewall of the isolation structure 7 corresponding to the second light-emitting unit is removed, so that the second electrode 5 of the second light-emitting unit can be extended until it is effectively electrically connected to the isolation structure 7 corresponding to the second light-emitting unit.

[0088] After removing the first sealing layer 9, the light-emitting functional layer, and the second electrode layer that are not covered by the second etching protection layer 11, the second light-emitting unit is formed by the first electrode 2, the light-emitting portion 4 of the first light-emitting unit, and the second electrode 5, and the second light-emitting unit is completely covered by the sealing unit 91, thereby reducing the risk of the deposition material being exposed to air before entering the deposition equipment, which can cause equipment contamination and breakage of the film layer.

[0089] In this way, without the need for a precise photomask, the light-emitting portion 4, the second electrode 5 and the sealing unit 91 are formed only in the pixel opening 31 corresponding to the second light-emitting unit, and the second electrode 5 may be electrically connected to the isolation structure 7, thereby making it possible to form the second light-emitting unit in the pixel opening 31 corresponding to the second light-emitting unit at a lower cost.

[0090] The first sealing layer 9 remaining on the side wall of the isolation structure 7 corresponding to the third light-emitting unit is removed by side etching, and at the same time, in the sealing unit 91 corresponding to the second light-emitting unit, the taper angle β2 between the side close to the isolation structure 7 and the side away from the isolation opening 6 in the part of the isolation structure 7 away from the array substrate 1 is set to be in the range of 30° to 80°, and for example, the taper angle β2 may be 30°, 35°, 45°, 55°, 65°, 75°, 80°, etc.

[0091] As shown in Figure 21, the light-emitting functional layer of the third light-emitting unit is formed on the side of the isolation structure 7 away from the array substrate 1, and the light-emitting functional layer of the third light-emitting unit extends to the side of the sealing unit 91 corresponding to the first light-emitting unit and the second light-emitting unit away from the array substrate 1.

[0092] On the basis of the first and second light-emitting units, a light-emitting functional layer of a third light-emitting unit is subsequently formed, and the light-emitting functional layer of the third light-emitting unit covers the sealing units 91 corresponding to the first and second light-emitting units, while forming the light-emitting portion 4 of the third light-emitting unit within the pixel opening 31 corresponding to the third light-emitting unit.

[0093] 22 , a second electrode layer is formed on the side of the light-emitting functional layer of the third light-emitting unit that is away from the array substrate 1. At the same time, a second electrode 5 of the third light-emitting unit is formed in the pixel opening 31 corresponding to the third light-emitting unit, and the second electrode 5 of the third light-emitting unit is electrically connected to the isolation structure 7.

[0094] As shown in FIG. 23, a first sealing layer 9 is formed on the side of the second electrode layer that is farther away from the array substrate 1.

[0095] As shown in FIG. 24, a third etching protection layer 12 is formed in the isolation opening 6 corresponding to the third light-emitting unit.

[0096] The third etching protection layer 12 can protect the corresponding light-emitting layer of the third light-emitting unit, the second electrode layer, and the first sealing layer 9 .

[0097] 25, the first sealing layer 9, the light-emitting functional layer, and the second electrode layer of the third light-emitting unit that are not covered by the third etching protective layer 12 are removed along the direction perpendicular to the array substrate 1, and the third etching protective layer 12 is also removed, thereby forming the light-emitting portion 4, the second electrode 5, and the sealing unit 91 in the pixel opening 31 corresponding to the third light-emitting unit, and the second electrode 5 extends until it is electrically connected to the isolation structure 7 corresponding to the third light-emitting unit. In the sealing unit 91 corresponding to the third light-emitting unit, at the side of the isolation structure 7 away from the array substrate 1, the taper angle β3 formed between the side close to the isolation structure 7 and the side away from the isolation opening 6 ranges from 80° to 90°.

[0098] Before forming the third light-emitting unit, the first sealing layer 9 on the sidewall of the isolation structure 7 corresponding to the third light-emitting unit is removed, so that the second electrode 5 of the third light-emitting unit can be extended until it is effectively electrically connected to the isolation structure 7 corresponding to the second light-emitting unit.

[0099] After removing the first sealing layer 9, the light-emitting functional layer, and the second electrode layer that are not covered by the third etching protection layer 12, the first electrode 2, the light-emitting portion 4 of the first light-emitting unit, and the second electrode 5 form a third light-emitting unit, which is completely covered by the sealing unit 91, thereby reducing the risk of the deposition material being exposed to air before entering the deposition device, which can cause equipment contamination and breakage of the film layer.

[0100] In this way, without the need for a precise photomask, the light-emitting portion 4, the second electrode 5 and the sealing unit 91 are formed only in the pixel opening 31 corresponding to the third light-emitting unit, and the second electrode 5 may be electrically connected to the isolation structure 7, thereby making it possible to form the third light-emitting unit in the pixel opening 31 corresponding to the third light-emitting unit at a lower cost.

[0101] In this embodiment, because no other light-emitting units 8 are manufactured after the third light-emitting unit, it is not necessary to side-etch the sealing unit 91 corresponding to the third light-emitting unit on the side of the isolation structure 7 that faces away from the array substrate 1 after manufacturing the third light-emitting unit. Therefore, the theoretical taper angle β3 of the sealing unit 91 corresponding to the third light-emitting unit is 90°. Because some error may occur in the manufacturing process, the taper angle β3 of the sealing unit 91 corresponding to the third light-emitting unit may be in the range of 80° to 90°, for example, the taper angle β3 may be 80°, 82°, 85°, 88°, or 90°. In this way, the step of side-etching the sealing unit 91 corresponding to the third light-emitting unit on the side of the isolation structure 7 that faces away from the array substrate 1 can be omitted, thereby reducing the manufacturing cost of the display panel.

[0102] In short, the display panel manufactured by the method of the present application can effectively overlap the second electrode 5 of the light-emitting unit 8 and the corresponding isolation structure 7, thereby improving the display effect of the display panel. At the same time, according to the manufacturing sequence of the first, second, and third light-emitting units, there is no need to side-etch the isolation structure 7 on the side away from the array substrate 1 in the sealing unit 91 corresponding to the third light-emitting unit, thereby reducing the manufacturing cost of the display panel. The first, second, and third light-emitting units each emit light of a different color; for example, the first light-emitting unit may be red, the second light-emitting unit may be green, and the third light-emitting unit may be blue.

[0103] In some possible embodiments, the present application further provides an electronic device, which includes a display panel according to the present application or a display panel manufactured by the method for manufacturing a display panel according to the present application. The electronic device may also include equipment with image processing capabilities, such as a server, a personal computer, a laptop, etc. Since the electronic device includes the display panel according to the present application, the display effect is better.

[0104] The technical features of the above embodiments can be combined in any way, and for the sake of simplicity, not all possible combinations of the technical features in the above embodiments are described, but as long as there is no contradiction in the combination of these technical features, it is deemed to be included in the scope described in the present invention.
