[0039] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0040] As described in the background art, when forming the encapsulation layer of a display panel in the related art, the material of the encapsulation layer easily flows into the non-display area, which is not conducive to achieving a narrow frame. The inventors have found that the reasons for this problem are as follows:

[0041] Figure 1 This is a schematic diagram of the structure of a display panel in the prior art. Figure 1 The display panel substrate 1 is provided with an encapsulation layer 2 and a barrier layer 3. The barrier layer 3 is used to prevent excess material from the encapsulation layer 2 from flowing into the non-display area. Since the encapsulation layer includes an organic layer, the organic material generally has a certain degree of fluidity before solidification. Therefore, during the production process of the encapsulation layer 2, the organic material can easily flow over the barrier layer 3 into the non-display area. This not only increases the risk of contaminating peripheral circuits, but also causes the non-display area to be too large, which is not conducive to achieving a narrow bezel of the display panel.

[0042] In view of the above problems, an embodiment of the present invention provides a display panel. Figure 2 Schematic diagram of the structure of a display panel provided by an embodiment of the present invention. Figure 2 The display panel includes: a substrate 10, an organic light-emitting structure 20, an encapsulation layer 30 and a barrier layer 40; wherein the substrate 10 includes a display area 11 and a non-display area 12; the organic light-emitting structure 20 is located in the display area 11 of the substrate 10; the encapsulation layer 30 covers the organic light-emitting structure; the barrier layer 40 and the organic light-emitting structure 20 are located on the same side of the substrate 10, and the barrier layer 40 is located in the non-display area 12 of the substrate 10, the barrier layer 40 surrounds the display area 11, and at least one opening 41 is provided on the side of the barrier layer 40 adjacent to the display area 11.

[0043] Specifically, the substrate 10 may be an array substrate of a display panel, and the substrate 10 may include a substrate and a driving circuit layer arranged on the substrate. The organic light-emitting structure 20 may include an anode, a cathode, and an organic light-emitting layer arranged between the anode and the cathode. The barrier layer 40 may be provided with a plurality of openings 41 on the side adjacent to the display area 11, and the opening 41 has a certain accommodation space. The encapsulation layer 30 may include an organic layer and an inorganic layer stacked at intervals. The organic layer has a certain fluidity during the manufacturing process. When there is a lot of organic material, the excess material may flow into the opening 41 of the barrier layer 40, thereby preventing the organic material from overflowing into the non-display area 12 on the side of the barrier layer 40 away from the display area 11, and preventing the overflowed organic material from contaminating the peripheral circuits. At the same time, it is beneficial to reduce the area of ​​the non-display area, thereby achieving the effect of a narrow frame.

[0044] The display panel provided in this embodiment includes a substrate, an organic light-emitting structure, an encapsulation layer, and a barrier layer. The substrate includes a display area and a non-display area. The organic light-emitting structure is located within the display area of ​​the substrate. The encapsulation layer covers the organic light-emitting structure. The barrier layer and the organic light-emitting structure are located on the same side of the substrate, and the barrier layer is located within the non-display area of ​​the substrate. The barrier layer surrounds the display area, and at least one opening is provided on the side of the barrier layer adjacent to the display area. The opening provided on the side of the barrier layer adjacent to the display area allows excess organic material produced during the encapsulation layer fabrication process to be contained within the opening on the side of the barrier layer, effectively preventing the encapsulation layer material from overflowing into the non-display area, thereby achieving a narrow bezel effect.

[0045] Figure 3 FIG is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention. Figure 3 Optionally, the barrier layer 40 includes a cavity 42 , and the opening 41 is connected to the cavity 42 .

[0046] The size of the cavity 42 can be set as needed. If too much organic material is present during the production of the encapsulation layer 30, the excess organic material can flow into the cavity 42 through the opening 41 of the barrier layer 40. The opening 41 and the cavity 42 can accommodate more organic material, thereby more effectively preventing the material of the encapsulation layer 30 from overflowing into the non-display area 12, thereby achieving a narrow frame effect.

[0047] It should be noted that the cavity 42 can be located on the side of the opening 41 adjacent to the substrate 10, so that the organic material can flow into the cavity 42 more quickly. In addition, the cavity 42 can also extend to the side of the opening 41 away from the substrate 10, so that the cavity 42 can accommodate more organic material.

[0048] Optionally, the cavity 42 extends to the bottom of the barrier layer 40. This configuration can increase the volume of the cavity 42 to accommodate more organic material, further preventing the material of the encapsulation layer 30 from overflowing into the non-display area 12, thereby achieving a narrow frame effect.

[0049] Figure 4 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 5 This is a structural diagram of another display panel provided by an embodiment of the present invention. Figure 4 and Figure 5 FIG. 4 is a top view of the display panel, which schematically illustrates the position of the opening 41. Figure 4 and Figure 5 Optionally, the side of the barrier layer 40 adjacent to the display area 11 includes a plurality of openings 41 , and the plurality of openings 41 are arranged in sequence along a direction surrounding the display area 11 ; alternatively, the barrier layer 40 includes one opening, and the opening 41 surrounds the display area 11 .

[0050] Specifically, when the barrier layer 40 includes multiple openings 41 on the side adjacent to the display area 11, the sizes of the multiple openings 41 can be the same or different, and this embodiment does not specifically limit this. For example, larger openings 41 can be provided at locations where more organic material overflows, and smaller openings 41 can be provided at locations where less organic material overflows. Furthermore, the multiple openings 41 can be evenly distributed along a direction surrounding the display area 11, so that excess organic material at each location can flow into the corresponding opening 41.

[0051] In this embodiment, multiple openings 41 are arranged in sequence along the direction surrounding the display area 11, so that excess organic material at various positions during the production process of the encapsulation layer 30 can be accommodated in the openings 41 of the barrier layer 40, preventing the material of the encapsulation layer 30 from overflowing into the non-display area 12.

[0052] In addition, the blocking layer 40 may be provided with an opening 41 surrounding the display area 11 , so that excess organic material produced during the production of the encapsulation layer 30 can flow directly into the opening 41 of the blocking layer 40 at any position, thereby further preventing excess organic material in the encapsulation layer 30 from overflowing into the non-display area 12 .

[0053] Furthermore, the arrangement of the cavities 42 can be the same as or different from that of the openings 41, and this embodiment is not particularly limited thereto. For example, when multiple openings 41 are arranged in sequence along a direction surrounding the display area 11, multiple cavities 42 can also be arranged in sequence along a direction surrounding the display area 11, with the cavities 42 and openings 41 communicating with each other in a one-to-one correspondence. When the barrier layer 40 includes an opening 41 surrounding the display area 11, the barrier layer 40 can also include a cavity 42, also arranged around the display area 11, with the opening 41 communicating with the cavity 42.

[0054] Optionally, refer to Figure 3 The encapsulation layer 30 includes a first inorganic layer 31, an organic layer 32, and a second inorganic layer 33, which are stacked. The first inorganic layer 31 is located on the side of the organic layer 32 adjacent to the substrate 10. The distance L1 between the surface of the barrier layer 40 away from the substrate 10 and the surface of the barrier layer 10 adjacent to the substrate 10 is greater than the sum of the thicknesses d of the organic layer 32 and the first inorganic layer 31. The distance L2 between the edge of the opening 41 away from the substrate 10 and the surface of the barrier layer 40 adjacent to the substrate 10 is greater than or equal to the sum of the thicknesses d of the organic layer 32 and the first inorganic layer 31. This arrangement ensures that if excessive organic material is present during the fabrication of the encapsulation layer 30, the excess organic material flows into the opening 41, preventing it from overflowing. Furthermore, the barrier layer 40 does not need to be excessively high, making the display panel thinner and lighter.

[0055] Optionally, the height of the barrier layer 40 is 10-50 μm, and the distance S1 between the edge of the opening 41 adjacent to the substrate 10 and the surface of the barrier layer 40 adjacent to the substrate 10 is 10-20 μm.

[0056] Specifically, if the barrier layer 40 is too thin, the opening 41 has limited space and cannot effectively block the material of the encapsulation layer 30. If the barrier layer 40 is too thick, the thickness of the display panel will increase. By setting the height of the barrier layer 40 to 10-50 μm, the opening 41 has a larger space and can be appropriately sized as needed to accommodate more material, better prevent the material of the encapsulation layer 30 from overflowing, and ensure that the display panel has a smaller thickness.

[0057] In addition, by setting the distance S1 between the edge of the opening 41 adjacent to the substrate 10 and the surface of the barrier layer 40 adjacent to the substrate 10 to 10-20 μm, the distance between the lower edge of the opening 41 and the surface of the barrier layer 40 adjacent to the substrate 10 is equal to the thickness of the encapsulation layer 30 or slightly greater than the thickness of the encapsulation layer 30, which can better prevent the organic material from overflowing.

[0058] It should be noted that the distance S1 between the lower edge of the opening 41 and the surface of the barrier layer 40 adjacent to the substrate 10 is determined by the thickness of the encapsulation layer 30. Since the thickness of the organic layer in the encapsulation layer 30 is relatively thick, the thickness of the organic layer accounts for the vast majority of the thickness of the encapsulation layer 30. Therefore, setting the position of the opening 41 according to the thickness of the encapsulation layer 30 can better prevent material overflow during the organic layer production process.

[0059] Exemplarily, the height of the blocking layer 40 is 30 μm, the thickness of the encapsulation layer 30 is 20 μm, and the distance between the edge of the opening 41 adjacent to the substrate 10 and the surface of the blocking layer 40 adjacent to the substrate 10 is 20 μm. At this time, the distance between the edge of the opening 41 adjacent to the substrate 10 and the surface of the blocking layer 40 adjacent to the substrate 10 is equal to the thickness of the encapsulation layer 30, which can make it easier for excess organic material in the encapsulation layer 30 to flow into the opening 41.

[0060] Optionally, along the height direction of the barrier layer 40 , a size S2 of the opening 41 is 1-10 μm.

[0061] Specifically, if the dimension S2 of the opening 41 is too small, the material of the barrier layer 30 will not flow easily into the opening 41, and the material of the encapsulation layer 30 will not be effectively blocked. If the dimension S2 of the opening 41 is too large, the upper edge of the opening 41 will easily approach the surface of the barrier layer 40 away from the substrate 10, affecting the structural strength of the barrier layer 30 and, consequently, the display panel. By setting the dimension S2 of the opening to 1-10 μm, excess organic material can flow more easily, and the opening 41 has a larger space to accommodate more material, better preventing the material of the encapsulation layer 30 from overflowing, and ensuring a high structural strength of the barrier layer and, consequently, the display panel.

[0062] For example, along the height direction of the barrier layer 40, the size S2 of the opening 41 is 5 μm. The above data are only for illustrative purposes and can be set according to actual needs, and are not limited here.

[0063] Optionally, the material used for the barrier layer 40 includes an organic material.

[0064] Specifically, the substrate 10 is typically formed with structures such as a pixel defining layer and support pillars. The pixel defining layer and support pillars are both made of organic materials. The barrier layer 40 is also made of an organic material. During fabrication, the barrier layer 40 can be made of the same material and in the same process as the pixel defining layer and / or support layer, thereby reducing process steps and costs. For example, the barrier layer 40 can include two stacked parts, the first part being made of the same material and in the same process as the pixel defining layer, and the second part being made of the same material and in the same process as the support pillars.

[0065] The display panel provided in this embodiment includes a substrate, an organic light-emitting structure, an encapsulation layer, and a barrier layer; the substrate includes a display area and a non-display area; the organic light-emitting structure is located within the display area of ​​the substrate; the encapsulation layer covers the organic light-emitting structure; the barrier layer and the organic light-emitting structure are located on the same side of the substrate, and the barrier layer is located within the non-display area of ​​the substrate, the barrier layer surrounds the display area, and at least one opening is provided on the side of the barrier layer adjacent to the display area, the barrier layer includes a cavity, the cavity is located on the side of the substrate adjacent to the opening, and the opening is connected to the cavity. In the display panel provided in this embodiment, the opening provided on the side of the barrier layer adjacent to the display area allows excess organic material during the production of the encapsulation layer to flow into the cavity through the opening of the barrier layer. The opening and the cavity can accommodate more organic material, thereby more effectively preventing the material of the encapsulation layer from overflowing into the non-display area, thereby achieving a narrow bezel effect.

[0066] An embodiment of the present invention further provides a display device, comprising the display panel described in any embodiment of the present invention, and thus having the corresponding structure and beneficial effects of the display panel, which will not be described in detail here.

[0067] Figure 6This is a flow chart of a method for manufacturing a display panel provided by an embodiment of the present invention. Figure 2 and Figure 6 , the production method comprises the following steps:

[0070] For example, the organic light-emitting structure includes an anode, a cathode, and an organic light-emitting layer disposed between the anode and the cathode. The organic light-emitting structure can be formed using an evaporation process. The barrier layer can be made of an organic material, and the main structure of the barrier layer can be formed through a coating, exposure, and development process. The openings in the barrier layer can be formed by applying a photoresist, followed by exposure, development, and dry etching.

[0071] S130 , forming an encapsulation layer, where the encapsulation layer covers the organic light-emitting structure.

[0072] Specifically, the encapsulation layer includes an organic layer and an inorganic layer. The organic layer is formed using processes such as inkjet printing, while the inorganic layer can be formed using processes such as chemical vapor deposition. The organic layer has a certain degree of fluidity during the formation process. When a large amount of organic material is formed during the organic layer formation process, the excess organic material can be accommodated by the openings in the barrier layer, effectively preventing the organic material from overflowing into the non-display area, thereby achieving a narrow bezel effect.

[0073] The method for manufacturing a display panel provided in this embodiment includes providing a substrate comprising a display area and a non-display area. An organic light-emitting structure and a barrier layer are formed on the substrate, with the organic light-emitting structure located within the display area. The barrier layer and the organic light-emitting structure are located on the same side of the substrate, and the barrier layer is located within the non-display area of ​​the substrate. The barrier layer surrounds the display area, and at least one opening is provided on a side of the barrier layer adjacent to the display area. An encapsulation layer is formed, covering the organic light-emitting structure. In the method for manufacturing a display panel provided in this embodiment, the barrier layer formed on the substrate is provided with an opening. Excess organic material produced during the encapsulation layer manufacturing process can be accommodated in the opening of the barrier layer, effectively preventing the organic material from overflowing into the non-display area, thereby achieving a narrow bezel effect.

[0074] Figure 7 Yes Figure 6 Detailed diagram of S130, reference Figure 7 Optionally, forming a barrier layer in the non-display area of ​​the substrate in S130 specifically includes the following steps:

[0075] S131, forming an organic adhesive layer on the substrate.

[0076] The organic adhesive layer may be formed by a coating process, and the organic adhesive layer may be formed as a whole layer or in a non-display area of ​​the substrate.

[0077] S132 , patterning the organic adhesive layer to form a barrier material layer.

[0078] Specifically, the organic glue layer may be patterned by exposure and development.

[0079] S133, coating a photoresist layer on the surface of the barrier material layer.

[0082] Specifically, the photoresist layer may be patterned by exposure and development.

[0083] S135 , etching the barrier material layer to form an opening, and the barrier material layer with the opening is a barrier layer.

[0084] For example, a gas such as plasma or reactive ion etching is used to etch the barrier material layer to form an opening. Gas etching has good etching selectivity and high etching rate, while reactive ion etching can greatly improve etching anisotropy. The gas used in the dry etching process can be selected according to actual needs.

[0085] S136, removing the photoresist layer.

[0086] The method for manufacturing a display panel provided in this embodiment is used to manufacture the display panel described in any embodiment of the present invention, and thus has the corresponding structure and beneficial effects of the display panel, which will not be described in detail here.

[0087] In one embodiment, a dry etching process can be used to etch the barrier material layer to form an opening and a cavity, and the opening and the cavity can be formed together by the dry etching process. The cavity can be formed on the side of the opening adjacent to the substrate, and the opening is connected to the cavity. The opening and the cavity can accommodate more organic material, thereby more effectively preventing the organic material of the encapsulation layer from overflowing into the non-display area, so as to achieve the effect of a narrow frame. Specifically, a plurality of openings can be formed, and the plurality of openings are arranged in sequence along the direction surrounding the display area, so that excess organic material at various positions during the production of the encapsulation layer can be accommodated in the opening of the barrier layer, preventing the material of the encapsulation layer from overflowing into the non-display area. Alternatively, an opening is formed, and the opening surrounds the display area, so that excess organic material at any position during the production of the encapsulation layer can directly flow into the opening of the barrier layer, thereby further preventing excess organic material of the encapsulation layer from overflowing into the non-display area.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
