DETAILED DESCRIPTION

[0066] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0067] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0069] Organic Light Emitting Diode (OLED) display technology is regarded as the most promising new flat panel display technology of the next generation. Compared with liquid crystal display technology, OLED display technology has the advantages of low energy consumption, low cost, self-luminescence, wide viewing angle and fast response speed.

[0070] In the process of realizing the present application, the inventors found the following problems in the related art: the display panel may include a substrate, and an isolation structure and a plurality of light-emitting units arranged on the substrate, the isolation structure encloses a plurality of isolation openings and light-transmitting holes, the plurality of isolation openings and the plurality of light-emitting units are arranged correspondingly, and the light-emitting units are at least partially arranged in the corresponding isolation openings. A packaging part may be arranged correspondingly on the side of the light-emitting unit facing away from the substrate, and the light-emitting unit and the packaging part are both arranged outside the light-transmitting hole. The display panel has a light-transmitting hole area, and the light-transmitting hole is arranged in the light-transmitting hole area.

[0071] However, in the subsequent process of forming the organic encapsulation layer, since the light-emitting unit and the encapsulation part are both arranged outside the light-transmitting hole, the isolation structure in the light-transmitting hole area has a large step difference and the light-transmitting hole is small in size, which makes it difficult for the organic encapsulation layer to level at the light-transmitting hole, resulting in poor flatness of the organic encapsulation layer, which makes it easy for pits to form in the organic encapsulation layer in the light-transmitting hole area. When the touch wiring is subsequently formed above the organic encapsulation layer, the touch wiring is easily broken at the pits, thereby affecting the touch performance of the display panel and even causing touch failure in the light-transmitting hole area.

[0072] In view of at least one of the above problems, embodiments of the present application provide a display panel and a display device, which can improve the flatness of a film layer subsequently formed on a side of a sealing member away from a substrate.

[0073] The following will be combined Figure 1-Figure 7 The display device provided in the embodiment of the present application is described.

[0074] The embodiment of the present application provides a display device, which may include a display panel 100. The display device may be an electronic paper, a mobile phone, a tablet computer, a television, a display, a laptop computer, a digital photo frame, a smart bracelet, a smart watch, a super personal computer, a navigator, a wireless device, a personal digital assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a camcorder, a game console, a clock, a calculator, a television monitor, a computer monitor, a car display (e.g., an odometer display, etc.), a cockpit controller and / or display, a display of a camera view (e.g., a display of a rear-view camera in a vehicle), an electronic billboard or sign, a projector, or other mobile or fixed terminals.

[0075] Exemplarily, the display panel 100 may be an organic light-emitting diode (OLED) display panel, a micro organic light-emitting diode (Micro OLED) display panel, a light emitting diode (LED) display panel, a quantum dot light emitting diode (QLED) display panel, a mini light emitting diode (Mini LED) display panel, a micro light emitting diode (Micro LED) display panel, or a liquid crystal (LCD) display panel, etc. The embodiment of the present application is described by taking an OLED display panel as an example.

[0076] The display panel 100 provided in the embodiment of the present application is described below.

[0077] See also Figure 1 In some embodiments, the display panel 100 has a display area 100a and a non-display area 100b. The display area 100a can be used to display images, and the non-display area 100b and the display area 100a can be arranged adjacent to each other. The non-display area 100b can be located on at least one side of the display area 100a. For example, the non-display area 100b can be arranged around the periphery of the display area 100a, and the non-display area 100b can form a "black border" surrounding the periphery of the display area 100a.

[0078] See also Figure 1 and Figure 2 The display area 100a may include a first display area 100a1 and a second display area 100a2 which are adjacent to each other, the light-transmitting hole 145 is disposed in the first display area 100a1, and the light-transmitting hole 145 is located outside the second display area 100a2. The transmittance of the display panel 100 in the second display area 100a2 may be less than the transmittance of the display panel 100 in the first display area 100a1.

[0079] For example, the first display area 100a1 is a light-transmitting display area, and the second display area 100a2 is a non-light-transmitting display area. A screen-under-function device may be provided on one side of the backlight surface of the display panel 100 of the first display area 100a1, and the screen-under-function device may include any one or more of a camera, a fingerprint reader, an infrared sensor, an iris reader, and a distance sensor. By providing a screen-under-function device on one side of the backlight surface of the display panel 100 of the first display area 100a1, on the one hand, the display panel 100 of the first display area 100a1 can display the image normally to ensure that the display panel 100 has a high screen-to-body ratio, and on the other hand, the first display area 100a1 has good light transmittance so that light can reach the screen-under-function device.

[0080] Exemplarily, the first display area 100a1 includes a light-transmitting hole area and a non-light-transmitting hole area that are adjacently arranged. The light-transmitting hole area is used to arrange the light-transmitting hole 145 , and the light-transmitting hole area and the light-transmitting hole 145 may overlap.

[0081] It should be noted that the display panel 100 may only be provided with the first display area 100a1, but not the second display area 100a2. The embodiment of the present application is described by taking the case where both the first display area 100a1 and the second display area 100a2 are provided as an example.

[0082] Exemplarily, the number of the first display area 100a1 may be at least one. When the number of the first display area 100a1 is plural, the plurality of first display areas 100a1 are arranged at intervals.

[0083] See also Figure 1 The embodiment of the present application provides a display panel 100, and the display panel 100 may include a substrate 105. The substrate 105 may provide support for other film layers that are subsequently arranged.

[0084] In some embodiments, see Figure 3 The display panel 100 may include an isolation structure 140 and a light emitting unit 130. Both the isolation structure 140 and the light emitting unit 130 may be disposed on one side of the substrate 105. The isolation structure 140 encloses a light-transmitting hole 145 and a plurality of isolation openings 144. The light-transmitting holes 145 and the isolation openings 144 are arranged at intervals. The plurality of isolation openings 144 are arranged corresponding to the plurality of light emitting units 130, and at least a portion of the light emitting unit 130 is arranged in the corresponding isolation openings 144. In this way, by arranging the light-transmitting holes 145 on the isolation structure 140, the light-transmitting holes 145 can allow ambient light to pass through, thereby improving the light transmittance of the display panel 100.

[0085] In the embodiment of the present application, the corresponding arrangement of A and B may refer to: one A is correspondingly arranged with at least one B, or one B is correspondingly arranged with at least one A. The embodiment of the present application is described by taking the corresponding arrangement of one A and one B as an example.

[0086] Exemplarily, there is at least one light-transmitting hole 145 . When there are multiple light-transmitting holes 145 , the multiple light-transmitting holes 145 are arranged at intervals.

[0087] Exemplarily, a light hole 145 is disposed between at least some of the two adjacent light emitting units 130 , for example, a light hole 145 is disposed between every two adjacent light emitting units 130 , thereby facilitating improving the transmittance of the display panel 100 in the first display area 100a1 .

[0088] The sealing member 110 provided in the embodiment of the present application is described below.

[0089] In some embodiments, see Figure 3 The display panel 100 includes a sealing member 110, which is at least partially disposed in the light-transmitting hole 145. The sealing member 110 can be disposed to compensate for the step difference at the light-transmitting hole 145, thereby improving the flatness of the film layer subsequently formed on the side of the sealing member 110 away from the substrate 105. For example, the flatness of the first encapsulation layer 161 subsequently formed on the side of the sealing member 110 away from the substrate 105 can be improved, thereby reducing the impact of the step difference at the light-transmitting hole 145 on the touch wiring 163 ( Figure 4 ) to improve the film formation continuity of the touch wiring 163 subsequently formed in the light transmission hole area, so as to reduce the breakage of the touch wiring 163, thereby improving the touch performance of the display panel 100 and the display device and alleviating the touch failure problem in the light transmission hole area.

[0090] In some embodiments, see Figure 4 The display panel 100 includes a touch line 163, and the touch line 163 is disposed on a side of the sealing member 110 away from the substrate 105. The touch line 163 is used to implement a touch function.

[0091] Exemplarily, the closure member 110 is used to close at least part of the light-transmitting hole 145, the overlapping area of ​​the orthographic projection of the closure member 110 on the substrate 105 and the corresponding orthographic projection of the light-transmitting hole 145 on the substrate 105 is the first area, the area of ​​the light-transmitting hole 145 is the second area, and the ratio of the first area to the second area is greater than or equal to 0.5, so that the overlapping area of ​​the orthographic projection of the closure member 110 on the substrate 105 and the orthographic projection of the light-transmitting hole 145 on the substrate 105 is larger, and the light-transmitting hole 145 can be better closed, so that the closure member 110 can better compensate for the fault at the light-transmitting hole 145, thereby alleviating the touch failure problem in the light-transmitting hole area. For example, the orthographic projection of the light-transmitting hole 145 on the substrate 105 can be the orthographic projection of the surface of the light-transmitting hole 145 on the side away from the substrate 105 on the substrate 105.

[0092] For example, the ratio of the first area to the second area may be 0.5, 0.6, 0.7, 0.8, 0.9, 1, or any value greater than 0.5.

[0093] In some embodiments, see Figure 3 and Figure 4 , located in the light-transmitting hole 145, along the thickness direction of the substrate 105, there is a first spacing between the surface of the sealing member 110 facing the substrate 105 and the surface of the isolation structure 140 facing the substrate 105, and the first spacing is greater than 0. That is, the surface of the sealing member 110 facing the substrate 105 and the surface of the isolation structure 140 facing the substrate 105 are spaced along the thickness direction of the substrate 105, which is conducive to raising the second extension portion 112 of the sealing member 110, reducing the depth of the sealing member 110 extending into the light-transmitting hole 145, and reducing the break of the sealing member 110 in the light-transmitting hole area, so as to improve the film formation continuity of the touch wiring 163 subsequently formed in the light-transmitting hole area, so as to reduce the breakage of the touch wiring 163, thereby improving the touch performance of the display panel 100 and the display device, and alleviating the touch failure problem in the light-transmitting hole area.

[0094] Exemplarily, the material of the sealing member 110 includes an inorganic material. The inorganic material has a good step coverage effect and can also reduce the preparation cost of the sealing member 110 .

[0095] For example, see Figure 3 The sealing member 110 includes a first extending portion 111 , and the first extending portion 111 is disposed on a side of the isolation structure 140 away from the substrate 105 , thereby facilitating improving the sealing effect of the sealing member 110 on the light-transmitting hole 145 .

[0096] Exemplarily, the sealing member 110 further includes a second extending portion 112 . The second extending portion 112 is located in the light-transmitting hole 145 . The second extending portion 112 is disposed on a side of the filling member 120 facing away from the substrate 105 .

[0097] For example, see Figure 3 , the first extension 111 includes a first surface facing away from the substrate 105, the second extension 112 includes a second surface facing away from the substrate 105, and the maximum distance d1 between the first surface and the second surface along the thickness direction of the substrate 105 is less than the depth d2 of the light-transmitting hole 145. In this way, in the light-transmitting hole area, the step difference of the sealing member 110 is less than the step difference of the light-transmitting hole 145, which is conducive to improving the film formation continuity of the touch wiring 163 subsequently formed in the light-transmitting hole area, so as to reduce the breakage of the touch wiring 163, thereby improving the touch performance of the display panel 100 and the display device, and alleviating the touch failure problem in the light-transmitting hole area. Among them, the maximum distance d1 between the first surface and the second surface along the thickness direction of the substrate 105 can be the maximum distance between the first surface and the surface of the fourth extension 114 facing away from the substrate 105.

[0098] Exemplarily, the distance between the orthographic projection of the side wall of the first extension portion 111 on the side away from the second extension portion 112 on the substrate 105 and the orthographic projection of the light-transmitting hole 145 on the substrate 105 is greater than or equal to 1 μm, so that the overlapping size of the first extension portion 111 and the isolation structure 140 is larger, which is conducive to reducing the peeling phenomenon between the first extension portion 111 and the isolation structure 140. For example, the distance between the orthographic projection of the side wall of the first extension portion 111 on the side away from the second extension portion 112 on the substrate 105 and the orthographic projection of the light-transmitting hole 145 on the substrate 105 is 1 μm, 1.5 μm, 2 μm, 2.5 μm or any value greater than 1 μm.

[0099] For example, see Figure 3 The second extension portion 112 includes a third extension portion 113 and a fourth extension portion 114 connected to each other. The third extension portion 113 is connected to the first extension portion 111. The third extension portion 113 is arranged on a side of the isolation structure 140 facing the light-transmitting hole 145, and the third extension portion 113 is in direct contact with the side wall of the isolation structure 140 facing the light-transmitting hole 145. The fourth extension portion 114 is used to connect the third extension portion 113 located in the light-transmitting hole 145, and a recess 116 is formed between the third extension portion 113 and the fourth extension portion 114.

[0100] The third extension portion 113 is in direct contact with the side wall of the isolation structure 140 facing the light-transmitting hole 145 , which is beneficial to improving the connection stability between the sealing member 110 and the isolation structure 140 .

[0101] For example, see Figure 4 , located in the light-transmitting hole 145, a filling member 120 is provided on the side of the sealing member 110 facing the substrate 105. For example, the filling member 120 can at least partially fill the space 1453 to be filled between the pixel defining layer 170 and the sealing member 110. The filling member 120 can reduce bubbles in the space 1453 to be filled, and the filling member 120 can also support the sealing member 110, which is beneficial to improve the structural stability of the sealing member 110. For example, the filling member 120 can completely fill the space 1453 to be filled between the pixel defining layer 170 and the sealing member 110, so as to better support the sealing member 110.

[0102] In some embodiments, see Figure 3 and Figure 6 The partial orthographic projection of the light-transmitting hole 145 on the substrate 105 is arranged outside the orthographic projection of the sealing member 110 on the substrate 105 , which is equivalent to that the sealing member 110 does not completely seal the light-transmitting hole 145 , and the sealing member 110 semi-seales the light-transmitting hole 145 .

[0103] Illustratively, in the process of depositing the light-emitting functional component 133 and the second electrode 132 of the light-emitting unit 130, the light-emitting functional component 133 and the second electrode 132 are not only deposited in the isolation opening 144, but also deposited in the light-transmitting hole 145. The light-transmitting hole 145 is not completely closed by the sealing member 110, so that the etching reagent can pass through the unclosed part of the light-transmitting hole 145 and enter the space to be filled 1453, so as to remove the light-emitting functional component 133 and the second electrode 132 of the light-emitting unit 130 located in the space to be filled 1453, so as to prevent the light-emitting functional component 133 and the second electrode 132 of the light-emitting unit 130 from having an adverse effect on the transmittance of the light-transmitting hole 145, so as to ensure the transmittance of the display panel 100 in the light-transmitting hole area.

[0104] For example, see Figure 6 The light-transmitting hole 145 includes a first area 14511 and at least one second area 14512. The orthographic projection of the first area 14511 on the substrate 105 is arranged within the orthographic projection of the closure member 110 on the substrate 105. The first area 14511 is a part of the light-transmitting hole 145 closed by the closure member 110. The orthographic projection of the second area 14512 on the substrate 105 is arranged outside the orthographic projection of the closure member 110 on the substrate 105. The orthographic projection of the second area 14512 on the substrate 105 does not overlap with the orthographic projection of the closure member 110 on the substrate 105. The second area 14512 is another part of the light-transmitting hole 145 that is not closed by the closure member 110. Since the second area 14512 is not sealed by the sealing member 110, the etching reagent can pass through the unsealed second area 14512 and enter the space to be filled 1453 to remove the light-emitting functional parts 133 and the second electrode 132 of the light-emitting unit 130 located in the space to be filled 1453, so as to prevent the light-emitting functional parts 133 and the second electrode 132 of the light-emitting unit 130 from having an adverse effect on the transmittance of the display panel 100 in the light-transmitting hole area.

[0105] In some embodiments, there are multiple second regions 14512, and the multiple second regions 14512 are arranged at intervals. By increasing the number of second regions 14512, the difficulty of the etching reagent entering the to-be-filled space 1453 through the second regions 14512 can be reduced, and the speed of the etching reagent entering the to-be-filled space 1453 can be increased, which is conducive to removing the light-emitting functional part 133 and the second electrode 132 of the light-emitting unit 130 located in the to-be-filled space 1453.

[0106] For example, see Figure 6 There are two second regions 14512 , and the two second regions 14512 are arranged on both sides of the first region 14511 . In this way, an excessive number of second regions 14512 can be avoided, which is helpful to reduce the difficulty of preparing the second regions 14512 .

[0107] Exemplarily, the second region 14512 is a strip hole, and the second region 14512 extends in a direction perpendicular to the first region 14511 to the second region 14512, so that the shape of the second region 14512 is relatively simple, which is conducive to reducing the difficulty of preparing the second region 14512. Among them, the extension length of the strip hole in the direction perpendicular to the first region 14511 to the second region 14512 is a first length, and the extension length of the strip hole in the direction from the first region 14511 to the second region 14512 is a second length, and the first length is greater than the second length.

[0108] Exemplarily, the size of the second region 14512 along the direction from the first region 14511 to the second region 14512 is greater than or equal to 1 μm, so that the size can be avoided to be too small, which is conducive to reducing the difficulty of the etching reagent entering the to-be-filled space 1453 through the second region 14512, and improving the speed of the etching reagent entering the to-be-filled space 1453, which is conducive to removing the light-emitting functional part 133 and the second electrode 132 of the light-emitting unit 130 located in the to-be-filled space 1453. For example, the size of the second region 14512 along the direction from the first region 14511 to the second region 14512 is 1 μm, 1.5 μm, 2 μm, 2.5 μm, or any value greater than 1 μm.

[0109] In some embodiments, see Figure 4 The display panel 100 further includes a first encapsulation layer 161, which is disposed on a side of the sealing member 110 away from the substrate 105, and the touch wiring 163 may be located on a side of the first encapsulation layer 161 away from the substrate 105. Due to the provision of the sealing member 110, the flatness and film-forming continuity of the first encapsulation layer 161 may be improved, so as to improve the flatness and film-forming continuity of the touch wiring 163, thereby alleviating the disconnection of the touch wiring 163 subsequently formed on the first encapsulation layer 161, so as to alleviate touch failure.

[0110] Exemplarily, the material of the first encapsulation layer 161 includes an organic material, which is helpful in relieving the stress of the display panel 100. For example, the first encapsulation layer 161 can be formed by inkjet printing. Since the sealing member 110 is provided, the first encapsulation layer 161 can be easily leveled after inkjet printing without forming pits, thereby relieving the disconnection of the touch wiring 163 subsequently formed on the first encapsulation layer 161, so as to alleviate touch failure.

[0111] Exemplarily, the surface of the first packaging layer 161 facing away from the substrate 105 is flush, thereby providing good planar support for the film layer subsequently formed on the first packaging layer 161 facing away from the substrate 105, which can better alleviate the breakage of the touch line 163 and better alleviate touch failure.

[0112] In the embodiment where the first encapsulation layer 161 and the second region 14512 are provided at the same time, the first encapsulation layer 161 can enter the to-be-filled space 1453 through the second region 14512, so that the filler 120 and the first encapsulation layer 161 can be prepared at the same time, which can simplify the preparation process of the filler 120 and the first encapsulation layer 161 and reduce the preparation cost. In this case, the filler 120 and the first encapsulation layer 161 are provided with the same material.

[0113] Exemplarily, the filling piece 120 and the first encapsulation layer 161 are an integral structure, which is beneficial to improving the connection stability between the filling piece 120 and the first encapsulation layer 161 and is beneficial to the structural stability of the filling piece 120 and the first encapsulation layer 161 .

[0114] See also Figure 3 In the embodiment where the sealing member 110 is formed with a recess 116, the first encapsulation layer 161 is disposed in the recess 116, thereby facilitating the reduction of bubbles in the recess 116. For example, the first encapsulation layer 161 may fill at least a portion of the recess 116, and the first encapsulation layer 161 in the recess 116 may support the first isolation portion 141.

[0115] In some embodiments, see Figure 7 , the orthographic projection of the light-transmitting hole 145 on the substrate 105 is set within the orthographic projection of the sealing member 110 on the substrate 105, which is equivalent to that the sealing member 110 completely seals the light-transmitting hole 145. Since the sealing member 110 completely seals the light-transmitting hole 145, during the formation process of the light-emitting functional part 133 and the second electrode 132 of the light-emitting unit 130, the etching reagent cannot enter the to-be-filled space 1453 through the light-transmitting hole 145, so that the light-emitting functional part 133 and the second electrode 132 of the light-emitting unit 130 located in the to-be-filled space 1453 are retained, so that part of the light-emitting unit 130 and the filling member 120 can be prepared at the same time, which can simplify the preparation process of part of the light-emitting unit 130 and the filling member 120 and reduce the preparation cost. At this time, the filling member 120 is set with the same material as the light-emitting functional part 133 and the second electrode 132 of the light-emitting unit 130.

[0116] Exemplarily, light-emitting units 130 of different colors can be prepared in steps. For example, the first light-emitting unit 130a and the second light-emitting unit 130b of different light-emitting colors can be prepared in steps. The filler 120 can be set with the same material as the light-emitting function 133 and the second electrode 132 of one of the first light-emitting unit 130a and the second light-emitting unit 130b. Alternatively, part of the filler 120 can be set with the same material as the light-emitting function 133 and the second electrode 132 of the first light-emitting unit 130a, and part of the filler 120 can be set with the same material as the light-emitting function 133 and the second electrode 132 of the second light-emitting unit 130b.

[0117] The packaging part 150 provided in the embodiment of the present application is described below.

[0118] In some embodiments, the display panel 100 includes a plurality of packaging parts 150 , and the plurality of packaging parts 150 are disposed corresponding to the plurality of light-emitting units 130 . The packaging parts 150 are disposed on a side of the corresponding light-emitting unit 130 facing away from the substrate 105 .

[0119] Exemplarily, the packaging portion 150 may cover the sidewalls of the isolation opening 144 , thereby facilitating improving the packaging effect of the packaging portion 150 .

[0120] Exemplarily, the packaging portion 150 is also arranged on the side of the isolation structure 140 away from the substrate 105, that is, the packaging portion 150 extends from the side of the light-emitting unit 130 away from the substrate 105 to the side of the isolation structure 140 away from the substrate 105, thereby improving the packaging effect of the packaging portion 150.

[0121] For example, see Figure 5 In the same packaging part 150, the packaging part 150 includes a first sub-packaging part 151 and a second sub-packaging part 152 that are connected. The first sub-packaging part 151 is arranged on the side of the isolation structure 140 away from the substrate 105, and the second sub-packaging part 152 is arranged in the isolation opening 144. The second sub-packaging part 152 can be arranged on the side of the light-emitting unit 130 away from the substrate 105, and the second sub-packaging part 152 can also cover the side wall of the isolation opening 144.

[0122] Exemplarily, the closing member 110 and the packaging portion 150 are made of the same material, which helps to simplify the preparation process of the closing member 110 and the packaging portion 150 and reduce the preparation cost.

[0123] In some embodiments, see Figure 3 The multiple light-emitting units 130 include a first light-emitting unit 130a and a second light-emitting unit 130b that are adjacently arranged, and the multiple packaging parts 150 include a first packaging part 150a and a second packaging part 150b. The first packaging part 150a is arranged corresponding to the first light-emitting unit 130a, and the second packaging part 150b is arranged corresponding to the second light-emitting unit 130b. The light-transmitting hole 145 is arranged between the first light-emitting unit 130a and the second light-emitting unit 130b.

[0124] Exemplarily, light-emitting units 130 of different colors can be prepared in steps, for example, the first light-emitting unit 130a and the second light-emitting unit 130b of different luminous colors can be prepared in steps. In addition, the encapsulation parts 150 corresponding to the light-emitting units 130 of different colors can be prepared in steps. For example, the first encapsulation part 150a and the second encapsulation part 150b can be prepared in steps. Among them, the closure 110 can be set with the same material as one of the first encapsulation part 150a and the second encapsulation part 150b. Alternatively, part of the closure 110 is set with the same material as the first encapsulation part 150a, and part of the closure 110 is set with the same material as the second encapsulation part 150b.

[0125] For some examples, see Figure 3 , at least one of the first encapsulation part 150a and the second encapsulation part 150b is spaced apart from the sealing member 110 along a direction parallel to the substrate 105. For example, the first encapsulation part 150a is spaced apart from the sealing member 110 along a direction parallel to the substrate 105, or the second encapsulation part 150b is spaced apart from the sealing member 110 along a direction parallel to the substrate 105, or both the first encapsulation part 150a and the second encapsulation part 150b are spaced apart from the sealing member 110 along a direction parallel to the substrate 105.

[0126] In some examples, the first light emitting unit 130a and the second light emitting unit 130b emit different colors of light, and one of the first packaging portion 150a and the second packaging portion 150b is an integral structure with the sealing member 110. Figure 5 , taking the first encapsulation part 150a and the sealing member 110 as an integrated structure as an example, such an arrangement can improve the structural stability of the first encapsulation part 150a and the sealing member 110, and is conducive to reducing the peeling phenomenon of the first encapsulation part 150a, the sealing member 110 and the isolation structure 140. At this time, the second encapsulation part 150b and the sealing member 110 can be arranged in a direction parallel to the substrate 105, or the orthographic projection of the first sub-encapsulation part 151 of the second encapsulation part 150b on the substrate 105 overlaps with the orthographic projection of the first extension part 111 of the sealing member 110 on the substrate 105.

[0127] In some examples, the first light emitting unit 130a and the second light emitting unit 130b emit different colors of light, and the first sub-encapsulation portion 151 ( Figure 5 ) on the substrate 105 and the first extension portion 111 ( Figure 5 ) overlap with each other in their orthographic projections on the substrate 105, thereby facilitating reduction of peeling between the first sub-encapsulation portion 151, the first extension portion 111 and the isolation structure 140 of at least one of the first encapsulation portion 150a and the second encapsulation portion 150b.

[0128] For example, see Figure 5 The first sub-encapsulation portion 151 of at least one of the first encapsulation portion 150a and the second encapsulation portion 150b is disposed on a side of the first extension portion 111 away from the substrate 105. Figure 6 ), in the process of forming the light-emitting functional part 133 and the second electrode 132 of the light-emitting unit 130, since the etching reagent can enter the space 1453 to be filled through the second area 14512 and remove the light-emitting functional part 133 and the second electrode 132 of the light-emitting unit 130 in the space 1453 to be filled, the second extension portion 112 will be in a suspended state for a period of time, so that the connection stability between the closure 110 and the isolation structure 140 is low during this time. By setting the first sub-packaging portion 151 of at least one of the first packaging portion 150a and the second packaging portion 150b on the side of the first extension portion 111 away from the substrate 105, the connection stability between the closure 110 and the isolation structure 140 can be improved, which helps to alleviate the accidental separation of the closure 110 from the isolation structure 140 under the action of the etching reagent. Among them, at least one of the first packaging part 150a and the second packaging part 150b and the sealing member 110 are prepared step by step, and the first sub-packaging part 151 of the second packaging part 150b is arranged on the side of the first extension part 111 away from the substrate 105, and the sealing member 110 is prepared before the second packaging part 150b.

[0129] Alternatively, the first sub-encapsulation portion 151 of at least one of the first encapsulation portion 150a and the second encapsulation portion 150b is disposed on a side of the first extension portion 111 facing the substrate 105. At least one of the first encapsulation portion 150a and the second encapsulation portion 150b and the sealing member 110 are prepared in steps, with the first sub-encapsulation portion 151 of the second encapsulation portion 150b being disposed on a side of the first extension portion 111 facing the substrate 105, and the sealing member 110 being prepared after the second encapsulation portion 150b.

[0130] The pixel defining layer 170 provided in the embodiment of the present application is described below.

[0131] In some embodiments, see Figure 2, the display panel 100 may include a pixel defining layer 170, and the pixel defining layer 170 may be disposed between the isolation structure 140 and the substrate 105, for example, the pixel defining layer 170 may be disposed between the isolation structure 140 and the first electrode 131. The pixel defining layer 170 defines a plurality of pixel openings 171, and the plurality of pixel openings 171 are disposed corresponding to the plurality of isolation openings 144, and the pixel openings 171 are connected to the corresponding isolation openings 144. For example, the orthographic projection of the pixel opening 171 on the substrate 105 may be located within the orthographic projection of the isolation opening 144 on the substrate 105. The light-emitting unit 130 may be at least partially located within the pixel opening 171. In this way, by providing the pixel defining layer 170, it is convenient to provide the light-emitting unit 130 on the substrate 105.

[0132] In some embodiments, the pixel defining layer 170 may not be disposed on the substrate 105, which is beneficial to simplifying the structure of the display panel 100, reducing the manufacturing cost of the display panel 100, and facilitating the thinning of the display panel 100. The embodiment of the present application is described as if the display panel 100 is provided with the pixel defining layer 170.

[0133] The isolation structure 140 provided in the embodiment of the present application is further described below.

[0134] Exemplarily, the isolation structure 140 may refer to an undercut structure with a larger top and a smaller bottom that can separate adjacent light-emitting functional components 133. The isolation structure 140 may be a structure formed by a single film layer or a structure formed by stacking multiple film layers.

[0135] Exemplarily, the cross-sectional shape of the isolation structure 140 may be an inverted trapezoid, a T-shape, an I-shape, or the like, which is “large at the top and small at the bottom”.

[0136] In some embodiments, see Figure 5 The isolation structure 140 may include a first isolation portion 141 and a second isolation portion 142. The second isolation portion 142 is located on the side of the first isolation portion 141 facing the substrate 105. The orthographic projection of the second isolation portion 142 on the substrate 105 is located within the orthographic projection of the first isolation portion 141 on the substrate 105, so that the isolation structure 140 forms an undercut structure with a "large top and small bottom", that is, the isolation structure 140 has an "eaves". In this way, in the process of forming the light-emitting functional component 133, the isolation structure 140 can separate two adjacent light-emitting functional components 133.

[0137] In some embodiments, see Figure 5, the isolation structure 140 may include a third isolation portion 143, the third isolation portion 143 may be located on a side of the second isolation portion 142 away from the first isolation portion 141, and the orthographic projection of the second isolation portion 142 on the substrate 105 may be located within the orthographic projection of the third isolation portion 143 on the substrate 105. Thus, in an embodiment where the material of the isolation structure 140 is a conductive material, the isolation structure 140 may reduce the resistance of the isolation structure 140 by providing the stacked first isolation portion 141, the second isolation portion 142 and the third isolation portion 143, thereby reducing the power consumption of the display panel 100.

[0138] Exemplarily, at least one of the first isolation portion 141, the second isolation portion 142, and the third isolation portion 143 may be made of a conductive material, and the conductive material may include metals such as titanium, silver, copper, aluminum, and molybdenum, or alloys, or conductive oxides, such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), aluminum zinc oxide (AZO), zinc gallium oxide, titanium tantalum oxide, tin oxide, cadmium oxide, and indium oxide. In other examples, at least one of the second isolation portion 142, the third isolation portion 143, and the first isolation portion 141 may be made of an insulating material, which is not limited in the embodiments of the present application.

[0139] For example, the material of the first isolation portion 141 may include at least one of titanium and molybdenum.

[0140] For example, the material of the second isolation portion 142 may include at least one of aluminum, copper, and silver.

[0141] For example, the material of the third isolation portion 143 may include at least one of titanium and molybdenum.

[0142] In an embodiment where at least one of the first isolation portion 141, the second isolation portion 142, and the third isolation portion 143 is made of a conductive material, the second electrode 132 may be electrically connected to the isolation structure 140. In this way, the second electrodes 132 located in the isolation openings 144 may be connected as a whole through the isolation structure 140, so that the second electrode 132 may be electrically connected to the second power line through the isolation structure 140, so as to apply a power supply voltage to the second electrode 132, thereby optimizing the wiring arrangement of the display panel 100.

[0143] In an embodiment where the material of the second isolation portion 142 is a conductive material, the second electrode 132 may be electrically connected to the second isolation portion 142 .

[0144] In an embodiment where the material of the third isolation portion 143 is a conductive material, the second electrode 132 may be electrically connected to the third isolation portion 143 .

[0145] In an embodiment in which the materials of the second isolation portion 142 and the third isolation portion 143 are both conductive materials, the second electrode 132 can be electrically connected to at least one of the second isolation portion 142 and the third isolation portion 143. For example, the second electrode 132 is connected to both the second isolation portion 142 and the third isolation portion 143, thereby improving the connection stability between the second electrode 132 and the isolation structure 140.

[0146] The composition, preparation and other contents of the isolation structure 140 mentioned in the embodiments of the present application are described in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 100935, PCT / CN2024 / 102785, PCT / CN2024 / 099419, PCT / CN2024 / 099072, and CN116685174A for reference.

[0147] The light emitting unit 130 provided in the embodiment of the present application is described below.

[0148] In some embodiments, see Figure 5 There may be a plurality of light emitting units 130, and the plurality of light emitting units 130 are arranged at intervals, for example, the plurality of light emitting units 130 may be arranged in an array.

[0149] Exemplarily, the light emitting unit 130 includes a first electrode 131 , a light emitting functional component 133 , and a second electrode 132 which are sequentially arranged in a direction away from the substrate 105 .

[0150] Exemplarily, a portion of the first electrode 131 is covered by the pixel defining layer 170 , and another portion of the first electrode 131 is exposed by the corresponding pixel opening 171 .

[0151] Exemplarily, a portion of the light-emitting functional component 133 is disposed in the corresponding pixel opening 171 and extends from the corresponding pixel opening 171 to the corresponding isolation opening 144 .

[0152] For example, the second electrode 132 may be at least partially located in the corresponding isolation opening 144 .

[0153] For example, one of the first electrode 131 and the second electrode 132 may be an anode, and the other of the first electrode 131 and the second electrode 132 may be a cathode. The present embodiment is described by taking the first electrode 131 as an anode and the second electrode 132 as a cathode as an example.

[0154] For example, the first electrode 131 may be electrically connected to a pixel driving circuit, the pixel driving circuit may be electrically connected to a first power line, and the second electrode 132 may be electrically connected to a second power line.

[0155] Exemplarily, one of the first power line and the second power line is used to transmit a low voltage, and the other is used to transmit a high voltage. For example, the first power line is used to transmit a high voltage, and the second power line is used to transmit a low voltage.

[0156] Exemplarily, the light-emitting functional part 133 may include a light-emitting layer (Emission layer, EML). In addition, the light-emitting functional part 133 may also include at least one 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).

[0157] Exemplarily, the plurality of light emitting units 130 include a red light emitting unit, a green light emitting unit, and a blue light emitting unit. In other examples, the plurality of light emitting units 130 may also include a white light emitting unit or light emitting units of other colors.

[0158] The other film layers provided in the embodiments of the present application are described below.

[0159] In some embodiments, see Figure 4 The second encapsulation layer 162 is disposed on the side of the first encapsulation layer 161 away from the substrate 105. The material of the second encapsulation layer 162 may include an inorganic material. The inorganic material has a good barrier effect on water and oxygen, which can improve the encapsulation effect. For example, the touch line 163 may be located on the side of the second encapsulation layer 162 away from the substrate 105.

[0160] In some embodiments, see Figure 4 A semiconductor layer 107, a first metal layer 101, a second metal layer 102, a third metal layer 103 and a fourth metal layer 104 may be stacked in sequence between the substrate 105 and the first electrode 131, and an insulating layer 106 is disposed between each two adjacent layers of the semiconductor layer 107, the first metal layer 101, the second metal layer 102, the third metal layer 103 and the fourth metal layer 104, and an insulating layer 106 is also disposed between the fourth metal layer 104 and the first electrode 131.

[0161] Exemplarily, the insulating layer 106 on the side of the fourth metal layer 104 facing away from the substrate 105 can be reused as the first planarization layer, and the first electrode 131 and the pixel defining layer 170 are both arranged on the side of the first planarization layer facing away from the substrate 105. The first planarization layer provides a good planar support for the subsequent formation of the film layer. A via 1062 may be provided in the insulating layer 106 on the side of the fourth metal layer 104 facing away from the substrate 105.

[0162] Exemplarily, at least a portion of the insulating layer 106 between the third metal layer 103 and the fourth metal layer 104 may be reused as a second planarization layer.

[0163] Exemplarily, a pixel driving circuit may be provided between the substrate 105 and the first electrode 131, and the pixel driving circuit includes a plurality of thin film transistors and a capacitor. The active layer of the thin film transistor may be formed by the semiconductor layer 107, the control terminal of the thin film transistor and the first plate of the capacitor may be formed by the first metal layer 101, the second plate of the capacitor may be formed by the second metal layer 102, and the source and drain of the thin film transistor may be formed by the third metal layer 103. The pixel driving circuit may be electrically connected to the first electrode 131 through the fourth metal layer 104 and the via 1062.

[0164] Exemplarily, the thin film transistor may include at least one of a metal oxide (MO) thin film transistor and a low temperature polysilicon (LTPS) thin film transistor, a high temperature polysilicon thin film transistor, and an amorphous silicon thin film transistor. For example, a low temperature polycrystalline oxide (LTPO) technology may be used, and LTPS thin film transistors and MO thin film transistors may be used as thin film transistors in a driving unit. LTPS thin film transistors may be used as driving thin film transistors, which have high mobility, can reduce driving voltage, and achieve high refresh rate and high resolution; MO thin film transistors may be used as switching thin film transistors, which have low leakage current, can enable the display panel 100 to maintain a good display effect at a low frame rate, and reduce the power consumption of the display panel 100. LTPO may combine the advantages of these two thin film transistors.
