Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel and a display device. Background Technology

[0002] In existing technologies, some display panels have openings that can serve as light transmission paths for cameras. Since these openings are exposed to the air, current technologies typically use a barrier between the display area and the opening to prevent external moisture intrusion. However, in existing structures, the complex stacking of the barrier layers and insufficient precision in the manufacturing process result in poor stacking of multiple patterned layers, leading to inadequate protection against cracks. Ultimately, these cracks become pathways for moisture intrusion. Utility Model Content

[0019] Preferably, the orthographic projection of the fifth portion of the second metal layer on the substrate at least partially overlaps with the orthographic projection of the second groove on the substrate, and the orthographic projection of the sixth portion of the second metal layer on the substrate at least partially overlaps with the orthographic projection of the second groove on the substrate.

[0032] Unlike existing technologies, the advantages of this application are as follows: The first metal layer of this application includes a first portion and a second portion that are interconnected. The second portion extends away from the first portion, thereby increasing the overall height of the first metal layer. This structure can effectively prevent crack intrusion. Furthermore, this application uses the first metal layer as a separating pillar, and there are no multiple patterned films between the first portion of the first metal layer and the substrate. This avoids the problem of poor stacking effect of multiple patterned films, thus reducing the difficulty of the fabrication process. Attached Figure Description

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] It should be noted that the terms "first" and "second" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0042] See Figure 1 and Figure 2 This application provides a display panel 10, which includes a display area AA, a transition area TA, and an aperture area HA. ​​The transition area TA surrounds the aperture area HA, and the display area AA surrounds the transition area TA. The display panel 10 includes: a substrate 110; and an isolation pillar 120 located on one side of the substrate 110 and within the transition area TA, including a first metal layer 121. The first metal layer 121 includes a first portion A1 and a second portion A2 that are interconnected. The extension direction of the first portion A1 is parallel to the extension direction of the substrate 110, and the second portion A2 extends away from the first portion A1.

[0043] Specifically, the display panel 10 includes a display area AA, a transition area TA, and an opening area HA. ​​The display area AA includes a display unit, the opening area HA is used to provide light to the camera assembly, and the transition area TA is formed between the display area AA and the opening area HA. ​​Since the opening area HA is exposed to the atmosphere, the transition area TA is used to block water vapor from entering the display area AA from the opening area HA to prevent the display unit in the display area AA from malfunctioning.

[0044] In the existing structure, there are micro-cracks near the boundary of the opening area HA in the transition area TA. These cracks will invade the display area AA. Once the barrier in the transition area TA cannot effectively block the cracks, the cracks will eventually become the path for moisture intrusion, thus causing the light-emitting unit in the display area AA to fail.

[0045] To address the problems in the prior art, the first metal layer 121 of this application includes a first portion A1 and a second portion A2 that are interconnected. The second portion A2 extends toward the side away from the first portion A1. It can be seen that the second portion A2 raises the height of the entire first metal layer 121 by extending, so that the final height of the first metal layer 121 is much greater than the thickness of the first portion A1 or the second portion A2 in the first metal layer 121. That is to say, when a crack enters the transition zone TA from the opening zone HA, the height barrier formed by the first portion A1 and the second portion A2 can block the extension of the crack. Of course, another difference between the structure of the isolation pillar 120 in this application and the prior art is that there are no multi-layered patterned films between the first portion A1 of the first metal layer 121 and the substrate 110. In the prior art, the main structure of the isolation pillar often uses multi-layered patterned films to increase the overall height. However, the fabrication precision of multi-layered patterned films is not ideal, which can lead to misalignment between the multi-layered patterned films during actual fabrication, resulting in a poorer film stacking effect and ultimately a poorer crack-blocking effect of the isolation pillar. In this application, the first metal layer 121 is directly used as the isolation pillar 120, and there are no multi-layered patterned films between the first portion A1 of the first metal layer 121 and the substrate 110, thus avoiding the problem of poor stacking effect of multi-layered patterned films. In summary, the isolation pillar 120 of this application can block crack intrusion while reducing the difficulty of the fabrication process.

[0046] In one embodiment, see Figure 3 The first metal layer 121 also includes a third part A3, which is connected to the first part A1 and extends away from the second part A2.

[0047] Specifically, the third part A3 is provided in the first metal layer 121. The extension directions of the third part A3 and the second part A2 are far apart from each other. The first part A1, the second part A2 and the third part A3 form an inverted roof structure, forming a multi-directional barrier. This back-to-back arrangement can enhance the barrier effect against cracks.

[0048] Preferably, the angle between the second part A2 and the first part A1 is greater than 90 degrees. For example, the angle can be 100 degrees, 120 degrees, or 150 degrees. This simplifies the fabrication process, ensures the connection between the first part A1 and the second part A2, and thus improves the reliability of the isolation column 120.

[0049] Preferably, the angle between the third part A3 and the first part A1 is greater than 90 degrees. For example, the angle can be 100 degrees, 120 degrees, or 150 degrees. This simplifies the fabrication process, ensures the connection between the first part A1 and the third part A3, and thus improves the reliability of the isolation column 120.

[0050] In one embodiment, see Figure 2 The second part A2 and the third part A3 are mirrored. This ensures that both layers have the same barrier effect.

[0051] Of course, in some other implementations, the third part A3 may not be provided.

[0052] In one embodiment, the material of the first metal layer includes at least one of titanium or aluminum. For example, the first metal layer may be a film layer composed of titanium, aluminum, and a combination of titanium layers, or it may be a layer consisting only of aluminum; this application does not impose any limitations.

[0053] In the above embodiments, this application does not specifically limit the shape of the second part A2 and the third part A3, which can be one or a combination of straight lines or arcs.

[0054] In one embodiment, see Figure 2 The display panel 10 includes a plurality of isolation pillars 120 and a planarization layer 130. The plurality of isolation pillars 120 are spaced apart on one side of the substrate 110 along the extension direction of the substrate 110. The planarization layer 130 fills the space between the second portion A2 and the third portion A3 of two adjacent isolation pillars 120.

[0055] Specifically, by forming a planarization layer 130 between the second part A2 and the third part A3 of the first metal layer 121 of the two adjacent isolation pillars 120, the planarization layer 130 can support the second part A2 and the third part A3 and improve the stability of the first metal layer 121. On the other hand, the planarization layer 130 can serve as a support surface for the preparation of the second part A2 and the third part A3, which can reduce the difficulty of preparation.

[0056] In one embodiment, see Figure 2 The planarization layer 130 includes a first planarization layer 131 and a second planarization layer 132 stacked together, with the first planarization layer 131 located between the second planarization layer 132 and the substrate 110.

[0057] Specifically, the two planarization layers stacked together can increase the overall height of the first metal layer 121, thereby enhancing the crack-blocking effect of the isolation pillar 120.

[0058] Of course, in addition to the two planarization layers in the above embodiments, more planarization layers can be provided in order to increase the overall height of the first metal layer. This application does not impose any specific restrictions on this.

[0059] In one embodiment, the height of the planarization layer is between 2 micrometers and 3 micrometers. Specifically, the height of the planarization layer can be 2 micrometers, 2.5 micrometers, or 3 micrometers, etc.

[0060] Of course, in some other implementations, the height of the planarization layer can also be greater than 3 micrometers.

[0061] In one embodiment, the planarization layer 130 may not be provided.

[0062] In one embodiment, see Figure 3 The planarization layer 130 is provided with a first groove C1, and the orthographic projection of at least part of the first groove C1 on the substrate 110 does not overlap with the orthographic projection of the isolation pillar 120 on the substrate 110.

[0063] Specifically, at least a portion of the first groove C1 corresponds to the gap between two adjacent isolation pillars 120. This is because, in subsequent processes, organic light-emitting materials need to be further deposited on the isolation pillars 120. By forming the first groove C1 between adjacent isolation pillars 120, the deposited organic light-emitting materials cannot form a continuous film layer. That is, the organic light-emitting materials on the isolation pillars 120 and the organic light-emitting materials in the first groove C1 are disconnected. On the one hand, this disconnection prevents electrical conductivity between the organic light-emitting materials, and on the other hand, it also blocks cracks.

[0064] In one embodiment, see Figure 3 The orthographic projection of the second portion A2 of the first metal layer 121 on the substrate 110 at least partially overlaps with the orthographic projection of the first groove C1 on the substrate 110, and the orthographic projection of the third portion A3 of the first metal layer 121 on the substrate 110 at least partially overlaps with the orthographic projection of the first groove C1 on the substrate 110.

[0065] Specifically, the first groove C1 extends to the inner side of the second part A2 and the inner side of the third part A3 of the first metal layer 121, so that the second part A2 and the third part A3 form an eaves-like structure, which can provide space for the accumulation of organic light-emitting materials and prevent the organic light-emitting layer material from climbing onto the first metal layer 121.

[0066] In one embodiment, see Figure 3 The first groove C1 extends through the planarization layer 130 in a direction perpendicular to the substrate 110.

[0067] Specifically, the first groove C1 extending through the entire planarization layer 130 can increase the depth of the first groove C1, thereby increasing the possibility of forming a continuous film layer for the organic light-emitting material, and further improving the crack blocking effect.

[0068] Of course, in some other embodiments, the first groove C1 may not be provided, and the organic light-emitting material may be prevented from forming a continuous film layer by etching the organic light-emitting material.

[0069] In one embodiment, see Figure 4 The isolation pillar 120 further includes a second metal layer 122, which is located between the first metal layer 121 and the substrate 110. The second metal layer 122 includes a fourth portion B1, a fifth portion B2, and a sixth portion B3. The fourth portion B1 extends in a direction parallel to the extension direction of the first portion A1, and the fourth portion B1 is in contact with the first portion A1. The fifth portion B2 extends away from the fourth portion B1, and the sixth portion B3 extends away from the fifth portion B2.

[0070] Specifically, the extension direction of the fourth part B1 in the second metal layer 122 is parallel to the extension direction of the first part A1 in the first metal layer 121, and the fourth part B1 and the first part A1 are in contact. Meanwhile, the extension structure of the fifth part B2 is similar to that of the second part A2, and the extension structure of the sixth part B3 is similar to that of the third part A3. The double metal layers can increase the overall height of the entire isolation pillar 120 and the thickness of the metal layers in the isolation pillar 120, thereby enhancing the effect of blocking cracks.

[0071] Preferably, the angle between the fifth part B2 and the fourth part B1 is greater than 90 degrees. For example, the angle can be 100 degrees, 120 degrees, or 150 degrees. This simplifies the fabrication process, ensures the connection between the fourth part B1 and the fifth part B2, and thus improves the reliability of the isolation column 120.

[0072] Preferably, the angle between the sixth part B3 and the fourth part B1 is greater than 90 degrees. For example, the angle can be 100 degrees, 120 degrees, or 150 degrees. This simplifies the fabrication process, ensures the connection between the fourth part B1 and the sixth part B3, and thus improves the reliability of the isolation column 120.

[0073] Of course, in some other embodiments, the isolation column may contain a greater number of metal layers similar to the first metal layer. This application does not limit the number of metal layers in the isolation column.

[0074] In one embodiment, see Figure 4The fifth part, B2, is located between the first planarization layer 131 and the second planarization layer 132. By setting a planarization layer to support a metal layer, a better support effect can be achieved.

[0075] In one embodiment, see Figure 4 Part B3, the sixth part, is located between the first planarization layer 131 and the second planarization layer 132. By setting a planarization layer to support a metal layer, a better support effect can be achieved.

[0076] In one embodiment, the first planarization layer 131 is provided with a second groove C2, the orthographic projection of the second groove C2 on the substrate 110 at least partially does not overlap with the orthographic projection of the isolation pillar 120 on the substrate 110; the second planarization layer 132 is provided with a third groove C3, the orthographic projection of the third groove C3 on the substrate 110 at least partially does not overlap with the orthographic projection of the isolation pillar 120 on the substrate 110.

[0077] Specifically, the arrangement of the second groove C2 and the third groove C3 ensures that the two adjacent isolation pillars 120 are completely separated without any filler in between. This prevents the organic light-emitting material that is subsequently deposited from forming a continuous film layer. In other words, the organic light-emitting material on the isolation pillar 120 is disconnected from the organic light-emitting material in the second groove C2 and the third groove C3. On the one hand, this disconnection prevents electrical conductivity between the organic light-emitting materials, and on the other hand, it also blocks cracks.

[0078] In one embodiment, the orthographic projection of the second portion A2 of the first metal layer 121 onto the substrate 110 at least partially overlaps with the orthographic projection of the third groove C3 onto the substrate 110, and the orthographic projection of the third portion A3 of the first metal layer 121 onto the substrate 110 at least partially overlaps with the orthographic projection of the third groove C3 onto the substrate 110; the orthographic projection of the fifth portion B2 of the second metal layer 122 onto the substrate 110 at least partially overlaps with the orthographic projection of the second groove C2 onto the substrate 110, and the orthographic projection of the sixth portion B3 of the second metal layer 122 onto the substrate 110 at least partially overlaps with the orthographic projection of the second groove C2 onto the substrate 110.

[0079] Specifically, the third groove C3 extends to the inner side of the second portion A2 and the inner side of the third portion A3 of the first metal layer 121, and the second groove C2 extends to the inner side of the fifth portion B2 and the inner side of the sixth portion B3 of the second metal layer 121. This allows the second portion A2, the fifth portion B2, the third portion A3, and the sixth portion B3 to all have a double-roof structure, providing more space for the accumulation of organic light-emitting materials and further preventing the organic light-emitting layer material from climbing onto the first metal layer 121 and the second metal layer 122. Of course, in some other embodiments, the second and fifth portions are in contact, and the third and sixth portions are in contact.

[0080] In one embodiment, the material of the second metal layer includes at least one of titanium or aluminum. For example, the second metal layer may be a film layer composed of titanium, aluminum, and a combination of titanium layers, or it may be a layer consisting only of aluminum; this application does not impose any limitations.

[0081] In one embodiment, see Figure 1 The display panel 10 also includes a filling layer 140, which fills the space between the second portion A2 and the third portion A3 of the same isolation column.

[0082] Specifically, the filling layer 140 is filled between the second part A2 and the third part A3 to fill the gap formed after the second part A2 and the third part A3 extend, and at the same time, the filling layer 140 can also protect the surface of the first metal layer 121.

[0083] In one application scenario, the filling layer 140 may include a first filling layer 141 and a second filling layer 142. The double filling layer is used to increase the filling effect on the isolation pillars. The first filling layer 141 may be a planarization layer in an existing display panel, and the second filling layer 142 may be at least one of a pixel definition layer or a support layer in an existing display panel.

[0084] In one embodiment, see Figure 2 and Figure 3 The orthographic projection of the filling layer 140 onto the substrate 110 overlaps with the orthographic projection of the second portion A2 onto the substrate 110.

[0085] Specifically, since the first groove C1 in the filling layer 140 needs to be etched during the fabrication process... Figure 2 The filling layer 140 is etched, and the first metal layer 121 is also etched at this time. In this embodiment, by covering the second part A2 with the filling layer 140, the second part A2 can be protected, thereby protecting the isolation pillar 120 and preventing it from being etched and affecting its barrier performance.

[0086] In one embodiment, see Figure 2 and Figure 3The orthographic projection of the filling layer 140 onto the substrate 110 overlaps with the orthographic projection of the third part A3 onto the substrate 110.

[0087] Specifically, its principle is similar to that of the above embodiments, both of which protect the isolation pillar 120 from being etched, and will not be described in detail in this application.

[0088] Of course, in some other embodiments, the filling layer 140 may not be provided. If the first metal layer 121 is made thicker, even if part of the first metal layer 121 is etched away, it will not affect the effect of the isolation pillar in blocking cracks.

[0089] In one embodiment, see Figure 5 The first part A1 is provided with at least a fourth groove C4, which extends through the first part A1 along an extension direction perpendicular to the substrate 110.

[0090] Specifically, the fourth groove C4 can divide the first part A1 into two, or the fourth groove C4 can separate the first part A1 and the second part A2, or the fourth groove C4 can separate the first part A1 and the third part A3. This application does not limit the specific location of the fourth groove C4 on the first part A1. As long as the first part A1 is penetrated, the second part A2 and the third part A3 can be isolated and cannot form an electrical connection. The effect is that even if the organic light-emitting material is placed on the second part A2 and the third part A3 in the subsequent preparation process, the organic light-emitting material on both sides cannot conduct due to the presence of the fourth groove C4, thus avoiding the occurrence of GDSH (hole area black spot) phenomenon.

[0091] In one embodiment, see Figure 5 The filling layer 140 also fills the fourth groove C4. This ensures the isolation effect between the second part A2 and the third part A3.

[0092] In another embodiment, as in Figure 4 In the structure of a double-layer metal layer, the same isolation effect can also be achieved by setting a first groove that runs through the first part and the fourth part.

[0093] Of course, in some other implementations, the fourth groove C4 may not be provided.

[0094] In one embodiment, see Figure 2 The second part A2 includes an inclined part A21 and a straight part A22 connected to each other. One end of the inclined part A21 is connected to the first part A1, and the other end of the inclined part A21 is connected to the straight part A22. The extension direction of the straight part A22 is parallel to the extension direction of the substrate 110.

[0095] Specifically, one end of the inclined portion A21 is connected to the first part A1, and the inclined portion A21 serves to increase the height of the entire first metal layer 121. The straight portion A22 is connected to the other end of the inclined portion A21, and the straight portion A22 makes the highest position of the first metal layer 121 tend to be straight, unlike the inclined portion A21 which has an upward angle. It can be understood that the setting of the straight portion A22 can ensure that the upper film layer covers the isolation pillar 120 better, especially which is conducive to improving the encapsulation effect of the subsequent encapsulation layer covering the isolation pillar 120.

[0096] Preferably, the angle between the inclined portion A21 and the first portion A1 is greater than 90 degrees. For example, the angle can be 100 degrees, 120 degrees, or 150 degrees. This simplifies the manufacturing process, ensures the connection between the inclined portion A21 and the first portion A1, and thus improves the reliability of the isolation column 120.

[0097] In one embodiment, see Figure 2 The display panel 10 includes at least one inorganic layer 150, which is located between the isolation pillar 120 and the substrate 110.

[0098] Specifically, the substrate 110 in existing display panels is usually made of organic materials, so its water resistance is not good. Water vapor usually enters from the substrate 110 side. However, this application provides at least one inorganic layer 150 between the isolation pillar 120 and the substrate 110, which can block water vapor from the substrate 110 side, thereby better protecting the display panel 10.

[0099] In one embodiment, at least the orthographic projection of the inorganic layer 150 on the substrate 110 overlaps with the orthographic projection of the transition region TA on the substrate 110.

[0100] Specifically, the inorganic layer 150 is covered on the substrate 110 of the transition region TA, thereby ensuring the water-blocking effect in the transition region TA.

[0101] Please see Figure 6 This application also provides a display device 20, which includes a display panel 10 as described above.

[0102] Specifically, the display device 20 can be any electronic device such as a laptop, desktop computer, tablet computer, mobile phone, smartwatch, or virtual display terminal, without any restrictions.

[0103] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
