[Modes for carrying out the invention]

[0044] Next, exemplary embodiments will be described in more detail with reference to the drawings. However, exemplary embodiments can be carried out in various forms and should not be understood as being limited to the embodiments described herein. In contrast, these embodiments are provided to ensure that this disclosure is comprehensive and complete and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures and therefore no further detailed description is given. Also, the drawings are merely schematic illustrations of this disclosure and are not necessarily drawn proportionally.

[0045] In this specification, relative terms such as “top” and “bottom” are used to describe the relative relationship between one component of an icon and other components, but for convenience, these terms are used only in the direction following the examples shown in the drawings, for example. If the icon's device is inverted upside down, it can be seen that the component described as “top” becomes the component “bottom.” When a structure is “top” another structure, it may mean that the structure is integrally formed with the other structure, that the structure is installed “directly” on the other structure, or that the structure is installed “indirectly” on the other structure.

[0046] The terms “one,” “one,” “that,” “mentioned,” and “at least one” are used to indicate the presence of one or more elements / components / etc. The terms “includes” and “have” are used to mean open inclusion, meaning elements / components / etc. that may exist in addition to the listed elements / components / etc. The terms “first,” “second,” “third,” etc. are used only as markers and do not imply a quantitative limitation on the subject.

[0047] To improve the user experience, display devices are evolving towards full-screen designs. Within this trend, punch-hole screens involve creating openings in the display panel and installing cameras within these openings, thereby increasing the screen area occupied by the display panel. This is the current trend in full-screen development. To ensure display effectiveness, it is necessary to separate the cathode and the light-emitting material layer via a partitioning mechanism and seal them using a sealing layer.

[0048] As shown in Figure 1, the partitioning means 21 is provided on one side of the base substrate 11, the light-emitting material layer 162 is provided on the side of the partitioning means 21 away from the base substrate 11, and the cathode is provided on the side of the light-emitting material layer 162 away from the base substrate 11, and the light-emitting material layer 162 and the cathode are separated by the partitioning means 21. However, in order to guarantee the partitioning effect of the partitioning means 21, the side of the partitioning means 21 closer to the base substrate 11 is inwardly concave (undercut) relative to the side away from the base substrate 11, and the sealing layer 17 tends to accumulate on the edge of the partitioning means 21, leading to morphological abnormalities and making it prone to cracking. Cracks become pathways for water and oxygen to enter, causing the seal to fail, and after water and oxygen enter, corrosion of the light-emitting material layer 162 fails, affecting normal display. Therefore, the main direction of improvement in the embodiments of this disclosure is how to mitigate or avoid corrosion of the light-emitting material layer and enhance the sealing effect of the display panel.

As shown in Figures 2 to 22, the display panel has a main region, the main region includes an opening region, a display region 100, and a transition region 200 connecting the display region 100 and the opening region, with an opening 300 provided in the opening region, the display panel includes a base substrate 11, at least one partitioning means 21, a sealing layer 17, and a first barrier layer, the at least one partitioning means 21 is provided on one side of the base substrate 11 and located in the transition region 200, the partitioning means 21 surrounds the opening 300, the partitioning means 21 includes at least one partition structure, the partition structure includes two partition layers, the width of the partition layer away from the base substrate 11 is greater than the width of the partition layer closer to the base substrate 11, and the sealing layer 17 includes a first sealing portion 1701, a second sealing portion 1702, and a first The first sealing portion 1701 is provided on the side of the partition means 21 away from the base substrate 11, the second sealing portion 1702 is provided between two adjacent partition means 21, the first sealing portion 1704 is connected between the first sealing portion 1701 and the second sealing portion 1702, the distance between the side of the first sealing portion 1701 away from the base substrate 11 and the base substrate 11 is greater than the distance between the side of the second sealing portion 1702 away from the base substrate 11 and the base substrate 11, the first barrier layer is provided on the side of the sealing layer 17 away from the base substrate 11, the first barrier layer includes at least one first barrier portion, and in the width direction of the first barrier portion, the orthographic projection of the first barrier portion onto the sealing layer 17 covers the first sealing portion 1704.

[0050] A sealing layer 17 is provided on the side of the partitioning means 21 away from the base substrate 11, and the sealing layer 17 includes a first connection portion 1704. A first barrier portion is provided on the side of the sealing layer 17 away from the base substrate, and in the width direction of the first barrier portion, the orthographic projection of the first barrier portion onto the sealing layer 17 covers the first connection portion 1704, preventing moisture from entering from the covered position of the first connection portion 1704, partitioning and extending the entry path of water and oxygen from the first connection portion 1704, mitigating or avoiding corrosion of the light-emitting material layer, enhancing the sealing effect of the display panel, and ensuring normal display of the display panel.

The pixel electrode 161 is located on the side of the first planarization layer 141 or the second planarization layer 142 that is away from the base substrate 11, the light-emitting material layer 162 is provided on the side of the pixel electrode 161 that is away from the base substrate 11, and the common electrode 163 is provided on the side of the light-emitting material layer 162 that is away from the base substrate 11. The pixel electrode 161 and the common electrode 163 drive the light-emitting material layer 162 to emit light and display an image.

[0061] The pixel electrode 161 is connected to either a first source 135 or a second source 138. A pixel boundary layer 15 is provided on the side of the pixel electrode 161 away from the base substrate 11. If the thin-film transistor includes only the first source 135, the pixel electrode 161 is connected to the first source 135, and the pixel boundary layer 15 covers the pixel electrode 161 and the first planarization layer 141. If the thin-film transistor also includes a second source 138, the pixel electrode 161 is connected to the second source 138, and the pixel boundary layer 15 covers the pixel electrode 161 and the second planarization layer 142.

[0062] The common electrode 163 can be the cathode, and the pixel electrode 161 can be the anode. By applying a signal to the pixel electrode 161, the emission of light from the light-emitting material layer 162 can be driven. A detailed explanation of the specific light emission principle is omitted here. The light-emitting material layer 162 can contain electro-organic light-emitting materials and can be formed using processes such as vapor deposition. For example, the light-emitting material layer 162 can include a hole injection layer, a hole transport layer, a photo-generating layer, an electron transport layer, and an electron injection layer sequentially stacked on the pixel electrode 161 layer. The light-emitting material layer 162 can also include a red light-emitting material layer, a green light-emitting material layer, and a blue light-emitting material layer, depending on the emission color.

[0063] Furthermore, the display panel of this disclosure may include a light-emitting layer 16 provided on the side away from the base substrate 11, and a sealing layer 17 that covers the light-emitting layer 16 to prevent hydroxylation erosion. The sealing layer 17 may be a single layer or a multilayer structure, and the material of the sealing layer 17 may include organic or inorganic materials, and is not particularly limited herein.

[0064] In this embodiment, the sealing layer 17 includes a first inorganic sealing layer 171, an organic sealing layer 172, and a second inorganic sealing layer 173, wherein the first inorganic sealing layer 171 is provided on the side of the light-emitting layer 16 away from the base substrate 11, the organic sealing layer 172 is provided on the side of the first inorganic sealing layer 171 away from the base substrate 11, and the second inorganic sealing layer 173 is provided on the side of the organic sealing layer 172 away from the base substrate 11.

[0065] The display panel includes a touch control layer 18, which is a mutually capacitive tactile control layer, and the touch control layer 18 includes a first touch control layer 182 and a second touch control layer 184, where the first touch control layer 182 is a metal mesh layer (MM) and the second touch control layer 184 is a bridge metal layer (BM), or the first touch control layer 182 is a bridge metal layer (BM) and the second touch control layer 184 is a metal mesh layer (MM).

[0066] Next, the first touch control layer 182 will be described as a metal mesh layer (MM), and the second touch control layer 184 as a bridge metal layer (BM). As shown in Figure 3, the first touch control layer 182 is located in the display area 100 and can be divided along the horizontal and vertical directions into a touch drive metal mesh 1821 and a touch sensor metal mesh 1822. Here, one of the touch sensor metal mesh 1822 and the touch drive metal mesh 1821 is connected to the other, and the other is connected via the second touch control layer 184. A first passivation layer 181 is provided on the side of the sealing layer 17 away from the base substrate 1, a first touch control layer 182 is provided on the side of the first passivation layer 181 away from the base substrate 11, a second passivation layer 183 is provided on the side of the first touch control layer 182 away from the base substrate 11, a second touch control layer 184 is provided on the side of the second passivation layer 183 away from the base substrate 11, and a coating layer 19 is provided on the side of the second touch control layer 184 away from the base substrate 11.

[0067] The touch control layer 18 further includes touch leads, which may include a first touch lead 1823 provided in the same layer as the first touch control layer 182 and a second touch lead 1824 provided in the same layer as the second touch control layer 184. The first touch lead 1823 is electrically connected to the touch drive metal mesh 1821, and the second touch lead 1824 is electrically connected to the touch sensor metal mesh 1822. The first touch lead 1823 and the second touch lead 1824 are located in the outer peripheral region 400 and are bound to the touch drive chip. The outer peripheral region 400 is connected to the edge of the display area.

[0068] By configuring the touch lead wire as a two-layer wiring including a first touch lead wire 1823 and a second touch lead wire 1824, even if one layer of wiring is partially broken, a touch signal can still be applied to the first touch control layer 182 through the other layer of wiring. This effectively solves the problem that a break in one layer of wiring can easily lead to touch failure. Furthermore, compared to a single-layer wiring design, a two-layer wiring design can also reduce the resistance value of the touch lead wires. In a specific embodiment, the first touch lead wire 1823 and the second touch lead wire 1824 can be electrically connected through a through-hole.

[0069] The main region further includes a transition region 200 located between the edge of the opening 300 and the edge of the display region 100. Due to the flow of the liquid organic sealing material, outflow of the liquid organic sealing material is likely to occur. Therefore, to prevent outflow of the organic sealing material, a barrier dam 20 is provided in the transition region 200. The barrier dam 20 is provided on the side of the protective layer 137 away from the base substrate 11, and the barrier dam 20 is provided around the opening 300, and the barrier dam 20 acts as a barrier. The cross-sectional shape of the barrier dam 20 may be rectangular or trapezoidal, and the barrier dam 20 has a slope on at least the side closer to the display region 100, but is not limited thereto.

[0070] The stacking pattern of the barrier dam 20 includes a group of insulating layers arranged in the same layer and made of the same material as one or more of the first planarization layer 141, the second planarization layer 142, and the pixel boundary layer 15. As shown in Figure 2, the stacking pattern of the barrier dam 20 all include the first insulating layer 201, and the first insulating layer 201 is made of the same layer and made of the same material as the first planarization layer 141. A second insulating layer 202 may be provided on the first insulating layer 201, and the second insulating layer 202 may be made of the same layer and made of the same material as the second planarization layer 142. A third insulating layer 203 may be provided on the second insulating layer 202, and the third insulating layer 203 may be made of the same layer and made of the same material as the pixel boundary layer 15.

[0071] The transition area 200 includes a first sub-transition area 2001 located between the edge of the barrier dam 20 and the edge of the opening 300, and a second sub-transition area 2002 located between the edge of the barrier dam 20 and the edge of the display area 100. In other words, the second sub-transition area 2002 is located closer to the display area 100, while the first sub-transition area 2001 is located further away from the display area 100 than the second sub-transition area 2002.

[0072] The first gate insulating layer 1321 and the second gate insulating layer 1322 extend from the display area 100 to the first sub-transition area 2001 and the second sub-transition area 2002, and the display panel further includes gate lines 24, including a first gate line 241 and a second gate line 242, with the first gate line 241 provided on the side of the first gate insulating layer 1321 away from the base substrate 11 in the first sub-transition area 2001, and the second gate line 242 provided on the side of the second gate insulating layer 1322 away from the base substrate 11. That is, the first gate line 241 is provided in the same layer and material as the first gate 1331, and the second gate line 242 is provided in the same layer and material as the second gate 1332.

[0073] The protective layer 137 extends from the display area 100 to the first sub-transition area 2001 and the second sub-transition area 2002. Partitioning means 21 are provided on the side of the protective layer 137 of the first sub-transition area 2001 and the protective layer 137 of the second sub-transition area 2002 that is away from the base substrate 11. The first sub-transition area 2001 is provided with a first partitioning means 211, and the second sub-transition area 2002 is provided with a second partitioning means 212. The first sub-transition area 2001 and the second sub-transition area 2002 are each provided with at least one partitioning means 21. To further enhance the partitioning effect, the first sub-transition area 2001 and the second sub-transition area 2002 are each provided with at least two partitioning means 21. For example, the first sub-transition area 2001 is provided with three first partitioning means 211, and the second sub-transition area 2002 is provided with three second partitioning means 212.

[0074] The width of at least a portion of the partitioning means 21 is smaller than the width on the side away from the base substrate 11. Specifically, the partitioning means 21 may have a structure in which the width at both ends is wider than the width in the middle, or it may have an inverted trapezoidal structure in which the width gradually decreases from the end away from the base substrate 11 toward the end closer to the base substrate 11, or it may have other structures that are recessed (undercut) in the height direction. For example, the partitioning means 21 can have a Ti-Al-Ti structure.

[0075] The light-emitting material layer 162 extends to the transition region 200 and is located on the side of the partitioning means 21 away from the base substrate 11. The light-emitting material layer 162 is partitioned by the partitioning means 21, forming a plurality of light-emitting material sections 22. Similarly, the common electrode 163 located on the side of the light-emitting material layer 162 away from the base substrate 11 is partitioned by the partitioning means 21, forming a plurality of common electrode sections 23. The light-emitting material section 22 is divided into a first light-emitting material section 221 provided on the side of the partitioning means 21 away from the base substrate 11, and a second light-emitting material section 222 provided between two adjacent partitioning means 21. Similarly, the common electrode section 23 is divided into a first common electrode section 231 and a second common electrode section 232, with the first common electrode section 231 provided on the side of the partitioning means 21 away from the base substrate 11, and the second common electrode section 232 provided between two adjacent partitioning means 21.

[0076] The distance between the surface of the second common electrode portion 232 of the first sub-transition region 2001 that is away from the base substrate 11 and the surface of the first common electrode portion 231 that is away from the base substrate 11 is the first distance, and the distance between the surface of the second common electrode portion 232 of the second sub-transition region 2002 that is away from the base substrate 11 and the surface of the first common electrode portion 231 that is away from the base substrate 11 is the second distance.

[0077] To ensure that the side of the first common electrode portion 231 of the first sub-transition region 2001 that is away from the base substrate 11 and the side of the first common electrode portion 231 of the second sub-transition region 200 that is away from the base substrate 11 are substantially on the same plane, multiple openings are provided in the protective layer 137 between two adjacent second partition means 212, the second common electrode portion 232 of the second sub-transition region 2002 is provided within the openings, and the second common electrode portion 232 is provided on the side of the second gate insulating layer 1322 that is away from the base substrate 11. The first partition means 211 is provided on the side of the protective layer 137 that is away from the base substrate 11. The width of the openings is smaller than the distance between two adjacent first partition means 211, thereby ensuring that the protective layer 137 between adjacent openings can effectively support the first partition means 211.

[0078] Since the second distance is equal to the sum of the thickness of the protective layer 137 and the height of the second partitioning means 212, the first distance is equal to the height of the first partitioning means 211, and the height of the second partitioning means 212 is equal to the height of the first partitioning means 211, it can be understood that the difference between the second distance and the first distance is the thickness of the protective layer 137. Since the thickness of the protective layer 137 is approximately equal to the sum of the thicknesses of the first gate line 241 and the second gate line 242, it can be ensured that the side of the first common electrode portion 231 of the first sub-transition region 2001 that is away from the base substrate 11 and the side of the first common electrode portion 231 of the second sub-transition region 2002 that is away from the base substrate 11 are on approximately the same plane.

[0079] As shown in Figures 3 and 4, the partitioning means 21 is either a single-layer partitioning means 21 or a double-layer partitioning means 21, and the display panel may include only the single-layer partitioning means 21, or it may include both the double-layer partitioning means 21 and the single-layer partitioning means 21 simultaneously. The double-layer partitioning means 21 includes a first partition structure 213 and a second partition structure 214, while the single-layer partitioning means 21 includes one of the first partition structure 213 and the second partition structure 214. The first partition structure 213 is installed in the same layer and of the same material as the first source drain metal layer, and the second partition structure 214 is installed in the same layer and of the same material as the second source drain metal layer.

[0080] The two-layer partitioning means 21 simultaneously comprises a first partition structure 213 and a second partition structure 214. On the other hand, the thickness of the two-layer partitioning means 21 is greater than the thickness of the single-layer partitioning means 21, achieving a superior partitioning effect. On the other hand, both the first partition structure 213 and the second partition structure 214 are equipped with anchor structures, which improves the strength of the display panel in the thickness direction and makes it easier to resist delamination of the film layer due to film layer stress problems during cutting.

[0081] A sealing layer 17 is provided on the side of the partitioning means 21 away from the base substrate 11. The sealing layer 17 of the transition region 200 includes a first sealing portion 1701, a second sealing portion 1702, and a first connecting portion 1704. The first sealing portion 1701 is provided on the side of the first common electrode portion 231 away from the base substrate 11, the second sealing portion 1702 is provided on the side of the second common electrode portion 232 away from the base substrate 11, and the first connecting portion 1704 is connected between the first sealing portion 1701 and the second sealing portion 1702. Because there is a step between the second common electrode portion 232 and the first common electrode portion 231, the distance between the surface of the first sealing portion 1701 away from the base substrate 11 and the base substrate 11 is greater than the distance between the surface of the second sealing portion 1702 away from the base substrate 11 and the base substrate 11. Therefore, cracks are likely to form at the connection point between the first sealing portion 1701 and the second sealing portion 1702, i.e., the first connection portion 1704.

[0082] A first barrier layer is provided on the side of the sealing layer 17 away from the base substrate 11, and the first barrier layer includes a first barrier portion, the number of which is equal to the number of partitioning means 21. The orthographic projection of the first barrier portion onto the base substrate 11 coincides with the orthographic projection of the first connection portion 1704 onto the base substrate 11. The contour shape of the first barrier layer is similar to the shape of the opening 300.

[0083] As shown in Figures 5 and 6, the first barrier layer includes a first barrier structure 254 and a second barrier structure 255, the first barrier structure 254 may include intermittently arranged first sub-barrier portions 2531. The orthographic projection of the first sub-barrier portions 2531 onto the base substrate 11 overlaps with the first connection portion 1704 of the first sub-transition region 2001. The second barrier structure 255 may include intermittently arranged second sub-barrier portions 2532. The orthographic projection of the second sub-barrier portions 2532 onto the base substrate 11 overlaps with the first connection portion 1704 of the second sub-transition region 2002. The first sub-barrier portions 2531 and the second sub-barrier portions 2532 are attached to the side of the sealing layer 17 away from the base substrate 11, and at least a portion of the second sub-barrier portions 2532 gradually curve toward the base substrate 11 along the direction toward the opening 300.

[0084] The side of the second partitioning means 212 away from the base substrate 11 is normally covered with an organic encapsulation layer 172, but the side of the first partitioning means 211 away from the base substrate 11 is not covered with an organic encapsulation layer 172. If there are fluctuations in the inkjet printing process when forming the organic encapsulation layer 172, the side of the second partitioning means 212 away from the base substrate 11 may not be covered with a thin organic encapsulation layer 172, or may not be covered at all.

[0085] In the transition region between the area uniformly covered by the organic encapsulating layer 172 and the area not covered, the distance between two adjacent first connection portions 1704 is relatively large, i.e., the width of the first encapsulating portion 1701 is relatively large. Typically, the width of the first encapsulating portion 1701 in the transition region is greater than the width of the first encapsulating portion 1701 in the area covered by the organic encapsulating layer 172. The area covered by the organic encapsulating layer 172 is relatively thick, while the area covered by the organic encapsulating layer 172 is relatively thin. The transition region refers to the curved surface region where the organic encapsulating layer 172 changes from a thick state to a thin state.

[0086] Therefore, in order to ensure that the second sub-barrier portion 2532 covers the second partitioning means 212, it is necessary to increase the width of the second sub-barrier portion 2532. The ratio of the width of the second sub-barrier portion 2532 to the width of the second partitioning means 212 is greater than the ratio of the width of the first sub-barrier portion 2531 to the width of the first partitioning means 211. Specifically, the ratio of the width of the first sub-barrier portion 2531 to the width of the first partitioning means 211 is 1.5-2, and the ratio of the width of the second sub-barrier portion 2532 to the width of the second partitioning means 212 is 2-3.

[0087] In other feasible embodiments, the second sub-barrier portion 2532 can be provided as a full-layer structure, i.e., the orthographic projection of the second sub-barrier portion 2532 onto the base substrate 11 covers all of the first sealing portions 1701, the second sealing portions 1702, and the first connecting portion 1704 in the second sub-transition region 2002. It should be further explained that the width of the second sub-barrier portion 2532 is at least twice the product of the width of the partition means 21 located in the second sub-transition region 2002 and the number of partition means 21, i.e., the width of the second sub-barrier portion 2532 is at least twice the product of the width of the second partition means 212 and the number of second partition means 212.

[0088] As shown in Figures 7 and 8, the partition structure includes a first partition layer 215, a second partition layer 216, and a third partition layer 217, which are sequentially installed along the direction away from the base substrate 11, with the width of the second partition layer 216 being smaller than the widths of the adjacent first partition layer 215 and third partition layer 217 on either side. The cross-sectional shape of the second partition layer 216 of the partition structure along the width direction of the partition means is trapezoidal. The width of the third partition layer 217 of the partition structure is smaller than the width of the first partition layer 215.

[0089] If the partitioning means is a two-layer partitioning means, the two-layer partitioning means includes a first partition structure 213 and a second partition structure 214 that are sequentially provided in a direction away from the base substrate, and the third partition layer 217 of the first partition structure is shared as the first partition layer 215 of the second partition structure. Of course, the third partition layer 217 of the first partition structure may also be provided stacked with the first partition layer 215 of the second partition structure. The cross-sectional shape of the partition means of the first partition structure 213 and the second partition layer 216 of the second partition structure 214, along the width direction, is trapezoidal, and the width of the first partition layer 215 of the first partition structure 213, the width of the third partition layer 217 (the first partition layer 215 of the second partition structure 214), and the width of the third partition layer 217 of the second partition structure 214 gradually decrease along the direction away from the base substrate.

[0090] Using the first sub-transition region in Figure 6 as an example, the single-layer partitioning means 21 can just meet the requirement for partition height, while the double-layer partitioning means 21 is much larger than this value and can fully guarantee the partitioning effect. Since the second sealing portions 1702 on both sides of the single-layer partitioning means 21 are flat, the first sub-barrier portion 2531 covered by the second sealing portion 1702 is flat. However, the first sub-barrier portions 2531 on both sides of the double-layer partitioning means 21 are not flat, and V-shaped depressions are formed in the second sealing portions 1702 on both sides of the first sealing portion 1701. The location of these depressions is the second connection portion 1705, which is prone to stress concentration points, leading to crack formation and the creation of water vapor passages.

[0091] When the first sub-barrier portion 2531 covers a portion of the second sealing portion 1702, the width of the first sub-barrier portion 2531 corresponding to the two-layer partitioning means 21 is greater than the width of the first sub-barrier portion 2531 corresponding to the one-layer partitioning means 21, in order to ensure that the first sub-barrier portion 2531 on the side of the two-layer partitioning means 21 away from the base substrate 11 completely covers the first connecting portion 1704. The ratio of the width of the first sub-barrier portion 2531 corresponding to the two-layer partitioning means 21 to the width of the two-layer partitioning means 21 is 2-3, and the ratio of the width of the first sub-barrier portion 2531 corresponding to the one-layer partitioning means 21 to the width of the one-layer partitioning means 21 is 1.5-2. After the first sub-barrier portion 2531 is covered on the surface of the second sealing portion 1702, the first sub-barrier portion 2531 forms a V-shaped recess, completely covering the second connecting portion 1705, and effectively creating a barrier against water and oxygen.

[0092] As shown in Figure 9, the second barrier structure 255 can be an overall layer structure, and the orthographic projection of the second barrier structure 255 onto the base substrate 11 covers all the first sealing portions 1701, the second sealing portions 1702, and the first connecting portion 1704 located in the first sub-transition region 2001 and the second sub-transition region 2002. The first barrier structure 254 includes at least two first sub-barrier portions 2531 provided on the other side of the first sub-transition region 2001 and the second sub-transition region 2002, and the orthographic projection of the first sub-barrier portion 2531 onto the sealing layer 17 is provided so as to overlap at least the first connecting portion 1704 in the width direction of the first sub-barrier portion 2531. Furthermore, the first barrier structure 254 is provided in the first sub-transition region 2001, and the second barrier structure 255 is provided in the second sub-transition region 2002.

[0093] As shown in Figures 10 and 11, in other feasible embodiments, the first barrier structure 254 may be an overall layer structure, the second barrier structure 255 may be an overall layer structure, the orthographic projection of the first barrier structure 254 onto the base substrate 11 may cover all first sealing portions, second sealing portions and first connection portions 1704 of the first sub-transition region 2001, and the orthographic projection of the second barrier structure 255 onto the base substrate 11 may cover all first sealing portions, second sealing portions and first connection portions 1704 of the second sub-transition region 2002.

[0094] The width of the first barrier layer is at least twice the product of the width of the partitioning means 21 and the number of partitioning means 21. Here, the width of the first barrier layer refers to the width of the first barrier layer as orthographically projected onto the base substrate 11.

[0095] If the first barrier layer includes a plurality of first barrier sections, the width of the first barrier layer refers to the sum of the widths of the plurality of first barrier sections and the width of the gap between adjacent first barrier sections. If the first barrier layer includes the first barrier structure 254 or the second barrier structure 255 of the overall structure, the width of the first barrier layer refers to the width of the first barrier structure 254 or the width of the second barrier structure 255. If the first barrier layer includes both the first barrier structure 254 and the second barrier structure 255 of the overall structure, the width of the first barrier layer refers to the sum of the width of the first barrier structure 254 and the width of the second barrier structure 255.

[0096] When the partitioning means 21 is a single-layer partitioning means 21, the single-layer partitioning means 21 has a relatively small height difference, and the partitioning effect is relatively poor. The first barrier layer includes a first sub-barrier layer 251 and a second sub-barrier layer 252, which can provide a better aqueous-oxygen partitioning effect. When the partitioning means 21 is a two-layer partitioning means 21, the two-layer partitioning means 21 has a relatively large height difference, and the partitioning effect is relatively good. The first barrier layer may include only the first sub-barrier layer 251 or the second sub-barrier layer 252.

[0097] The first barrier layer includes a first sub-barrier layer 251 and / or a second sub-barrier layer 252, wherein the first sub-barrier layer 251 is the same layer and made of the same material as one of the first touch control layer and the second touch control layer, and the second sub-barrier layer 252 is the same layer and made of the same material as the other of the first touch control layer and the second touch control layer. The materials for the first and second touch control layers include, but are not limited to, Al, Ag, Cu, Ti-Al-Ti, and ITO.

[0098] In Figure 6, the first sub-barrier layer 251 can include a plurality of sub-first sub-barrier portions 2511, and the second sub-barrier layer 252 includes a plurality of sub-second sub-barrier portions 2521 that correspond one-to-one with the sub-first sub-barrier portions 2511. That is, the orthographic projection of the sub-second sub-barrier portion 2521 onto the base substrate 11 overlaps with the orthographic projection of the sub-first sub-barrier portion 2511 onto the base substrate 11. As shown in Figure 11, when the sub-second sub-barrier portion and the sub-first sub-barrier portion have an integrated layer structure, it can be understood that the sub-second sub-barrier portion and the sub-first sub-barrier portion also correspond to each other.

[0099] On the side of the barrier dam 20 away from the base substrate 11, a third light-emitting material portion 223, a third common electrode portion 233, a third sealing portion 1703, a first passivation layer 181, and a second passivation layer 183 are provided in that order. As shown in Figure 12, the third sealing portion 1703 is provided on the side of the barrier dam 20 away from the base substrate 11, and if the angle between the slope of the barrier dam 20 and the base substrate 11 is greater than 50°, it becomes easier to form a third connection portion 1706 at the second connection point between the third sealing portion 1703 and the second sealing portion 1702. A second barrier layer 26 is further provided on the side of the sealing layer 17 away from the base substrate 11, and the orthographic projection of the second barrier layer 26 onto the base substrate 11 covers the third connection portion 1706. The second barrier layer has an inner contour and an outer contour, and the shape of the inner contour 261 and the outer contour 262 of the second barrier layer are both similar to the shape of the opening 300.

[0100] Referring to Figures 7, 8, and 12, in order to ensure the barrier effect of the first barrier layer and the second barrier layer 26, the first sub-barrier portion 2531 covers the first sealing portion 1701, the first connecting portion 1704, and a portion of the second sealing portion 1702 located at the edge of the first sealing portion 1701. The second barrier layer 26 covers the third sealing portion 1703, the third connecting portion 1706, and a portion of the second sealing portion 1702 located at the edge of the third sealing portion 1703.

[0101] As shown in Figures 13 and 14, the partition means 21 extends in a direction parallel to the base substrate 11, and the orthographic projection of the partition means 21 onto the base substrate 11 is a continuous and uninterrupted closing pattern, and the partition means 21 is not signal-connected. The shape of the contour of the partition means 21 is similar to the shape of the opening 300. For example, if the shape of the opening 300 is circular, the shape of the partition means 21 is annular. The number of partition means may be two as shown in Figure 13, or six as shown in Figure 14. However, the number of partition means is at least greater than two.

[0102] As shown in Figures 15 and 16, the first barrier layer includes an intermittent first sub-barrier portion 2541 and an intermittent second sub-barrier portion 2551. The orthographic projection of the intermittent first sub-barrier portion 2541 onto the base substrate 11 coincides with the orthographic projection of the first connecting portion corresponding to the first partitioning means 211 onto the base substrate 11, and the orthographic projection of the intermittent second sub-barrier portion 2551 onto the base substrate coincides with the orthographic projection of the first connecting portion corresponding to the second partitioning means 212 onto the base substrate.

[0103] If the number of intermittent first sub-barrier portions 2541 is the same as the number of first partitioning means 211, and the number of intermittent second sub-barrier portions 2551 is the same as the number of second partitioning means 212, and the partitioning means includes one first partitioning means 211 and one second partitioning means 212, then the first partition layer includes intermittent first sub-barrier portions 2541 and intermittent second sub-barrier portions 2551. If the partitioning means includes three first partitioning means 211 and three second partitioning means 212, then the first barrier layer includes three intermittent first sub-barrier portions 2541 and three intermittent second sub-barrier portions 2551.

[0104] An intermittent first sub-barrier section 2541 is provided with an intermittent location 256, and an intermittent second sub-barrier section 2551 is provided with an intermittent location 256. Along the extending direction of the intermittent first sub-barrier section 2541, a first barrier segment is formed between two adjacent intermittent locations 256, and the length of the first barrier segment of the same intermittent first sub-barrier section 2541 and the same intermittent second sub-barrier section 2551 is greater than the length of the intermittent location 256.

[0105] As shown in Figure 15, when the first barrier layer includes intermittent first sub-barrier portions 2541 and intermittent second sub-barrier portions 2551, the intermittent locations 256 of two adjacent intermittent first sub-barrier portions 2541 and the intermittent locations 256 of two adjacent intermittent second sub-barrier portions 2551 are offset from each other along the extending direction of the edge of the far-away opening 300. As shown in Figure 16, when the first barrier layer includes multiple intermittent first sub-barrier portions 2541, the intermittent locations 256 of two adjacent intermittent first sub-barrier portions 2541 are offset from each other along the extending direction away from the edge of the opening 300, and when the first barrier layer includes multiple intermittent second sub-barrier portions 2551, the intermittent locations 256 of two adjacent intermittent second sub-barrier portions 2551 are offset from each other.

[0106] The first barrier segment covers a portion of the first connection portion 1704, preventing water vapor from entering from the covered area of ​​the first connection portion 1704, allowing it to pass only through the intermittent locations 256 of the intermittent first barrier portion. Two adjacent intermittent locations 256 of the intermittent first barrier portion are offset from each other along the extending direction of the partition means 21, extending the entry path for water and oxygen from the first connection portion 1704. The length of a single first barrier segment is short, reducing electrostatic buildup during the formation process of the first barrier portion and lowering the risk of damage to the display panel due to electrostatic discharge.

[0107] As shown in Figures 17 to 21, in addition to Figures 15 and 16, the first barrier layer includes a continuous, whole-closed first barrier section, the orthographic projection of the closed first barrier section onto the base substrate 11 covers the base substrate 11 of the partition means 21. The closed first barrier section completely prevents water vapor from entering the interior of the display panel from the corresponding first connection section 1704.

[0108] As shown in Figures 17 to 20, the first barrier layer may include one closed first barrier section and two intermittent first barrier sections, the two intermittent first barrier sections may be provided on both sides of the closed first barrier section, the closed first barrier section may be provided close to the opening 300, or the two intermittent first barrier sections may be provided away from the opening 300, that is, close to the display area 100. To better prevent the entry of water vapor, the closed first barrier section is usually provided away from the opening 300, and the two intermittent first barrier sections are provided close to the opening 300. After the water vapor entry path is extended by the two intermittent first barrier sections, the amount of water vapor is reduced to some extent, and the closed first barrier section further provides a barrier, resulting in a relatively good barrier effect against water vapor.

[0109] The first sub-transition region 2001 or the second sub-transition region 2002 may be provided with a closed first barrier portion and two intermittent first barrier portions. As shown in Figure 17, the first barrier layer includes two intermittent first sub-barrier portions 2541 and one closed first sub-barrier portion 2542. As shown in Figure 18, the first barrier layer includes two intermittent second sub-barrier portions 2551 and one closed second sub-barrier portion 2552. As shown in Figure 19, one intermittent first barrier portion may be provided in the first sub-transition region 2001, and the other intermittent first barrier portion and the closed first barrier portion may be provided in the second sub-transition region 2002. The first barrier layer includes one intermittent first sub-barrier portion 2541, one intermittent second sub-barrier portion 2551, and one closed second sub-barrier portion 2552. As shown in Figure 20, the first sub-transition region 2001 may have two intermittent first barrier sections, and the second sub-transition region 2002 may have a first barrier section; that is, the first barrier layer may include two intermittent first sub-barrier sections 2541 and one closed second sub-barrier section 2552.

[0110] As shown in Figure 21, the first barrier layer includes a plurality of intermittent first barrier sections and a plurality of closed first barrier sections, and the plurality of intermittent first barrier sections are arranged sequentially and alternately along the direction away from the opening 300. The plurality of closed first barrier sections and the plurality of intermittent first barrier sections alternately shield the water vapor path and extend the water vapor path, thereby better preventing water vapor from entering the inside of the display panel.

[0111] The first barrier layer includes at least one closed first barrier portion and at least two intermittent first barrier portions, the closed first barrier portion being arranged as a continuous whole, the orthographic projection of the closed first barrier portion onto the base substrate covering the orthographic projection of the partitioning means onto the base substrate, the intermittent first barrier portion having intermittent portions, and in the direction away from the opening 300, at least some of the intermittent portions of the intermittent first barrier portion are located on the same straight line along the width direction perpendicular to the partitioning means 21.

[0112] As shown in Figure 22, the first barrier layer includes three closed first barrier sections and three intermittent first barrier sections, with the three closed first barrier sections and the three intermittent first barrier sections alternately distributed along the direction away from the opening 300, and the portion of the first barrier layer closest to the opening 300 can be designated as a closed first barrier section. The intermittent locations of the three intermittent first barrier sections are all located on the same straight line along the width direction perpendicular to the partition means 21, obstructing the water vapor path and reducing the risk of damage to the display panel due to electrostatic discharge.

[0113] The intermittent first barrier section includes an intermittent first sub-barrier section 2541 and an intermittent second sub-barrier section 2551, and the distance between adjacent first barrier segments of the intermittent first sub-barrier section 2541 is smaller than the distance between adjacent first barrier segments of the intermittent second sub-barrier section 2551. Because a large amount of water vapor enters the first connection section 1704 near the opening 300, the width of the intermittent section 256 of the intermittent first sub-barrier section 2541 near the opening 300 is small, and the amount of water vapor gradually decreases as it moves away from the opening 300, so even if the width of the intermittent section 256 of the intermittent first sub-barrier section 2541 away from the opening 300 is large, the entry of water vapor can be effectively prevented.

[0114] The length of the first barrier portion of each intermittent first barrier portion gradually increases along the direction away from the opening. Specifically, the length of the first barrier segment of each intermittent first sub-barrier portion 2541 and the length of the first barrier segment of each intermittent second sub-barrier portion 2551 both gradually increase along the direction away from the opening, and the length of the first barrier segment of any intermittent first sub-barrier portion 2541 is smaller than the length of the first barrier segment of any intermittent second sub-barrier portion 2551.

[0115] The distance L2 between adjacent second sub-barrier sections is smaller than the distance L1 between adjacent first sub-barrier sections. The distribution density of first sub-barrier sections closer to the display area 100 is greater than the distribution density of first sub-barrier sections further away from the display area 100. The greater the density of intermittent first sub-barrier sections, the longer the water vapor entry path becomes, the greater the density of the closing first partition means becomes, and the more times the water vapor is blocked. Therefore, whether the first barrier layer adopts the structure shown in Figures 15 and 16 or the structure shown in Figures 17 to 21, it is possible to better prevent water vapor from entering the display panel from the sealing layer 17.

[0116] Furthermore, the distance between the partitioning means 21 located in the first sub-transition region 2001 and the edge of the opening 300 is smaller than the distance between the partitioning means 21 located in the second sub-transition region 2002 and the edge of the display region 100. That is, the distance between the first partitioning means 211 and the edge of the opening 300 is smaller than the distance between the second partitioning means 212 and the edge of the display region 100. The distance between the second partitioning means 212 and the edge of the display region 100 is large, which prevents short circuits between the first barrier layer of the display region 100 and the touch control layer 18, while the distance between the first partitioning means 211 and the edge of the opening 300 is small, which allows the first barrier layer to protect the elements within the opening 300.

[0117] Furthermore, both the partitioning means 21 and the first barrier layer have inner and outer contours, and the shapes of the inner contour 218 and outer contour 219 of the partitioning means, the shape of the inner contour 257 and outer contour 258 of the first barrier layer are all similar to the shape of the opening 300.
