Description

Technical Field

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

[0002] Organic light-emitting diode (OLED) display panels and other flat panel display panels utilizing light-emitting diode (LED) devices are widely used in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, laptops, and desktop computers due to their advantages such as high image quality, energy saving, thin body, and wide application range, becoming the mainstream in display devices. However, current display panels suffer from poor yield rates in the edge areas. Summary of the Invention

[0003] The purpose of this application is to at least solve the problem of poor yield in the edge area of ​​display panels. This purpose is achieved through the following technical solution:

[0004] The first aspect of this application discloses a display panel, the display panel including a display area and a border area located outside the display area, the display panel comprising:

[0005] An array substrate, the array substrate including a metal structure located in the border region;

[0006] The light-emitting layer is located on one side of the array substrate;

[0007] A filter layer is located on the side of the light-emitting layer opposite to the array substrate. The filter layer is partially located in the frame area. The orthographic projection of the filter layer on the array substrate at least partially overlaps with the orthographic projection of the metal structure on the array substrate.

[0008] The encapsulating adhesive is located on the side of the filter layer opposite to the array substrate and in the border area;

[0009] A light-shielding layer is located on the side of the encapsulant facing away from the array substrate and in the border area. The light-shielding layer includes a light-shielding area and multiple light-transmitting areas. The orthographic projection of the light-transmitting area on the array substrate is located within the orthographic projection of the encapsulant on the array substrate, and the orthographic projection of the light-transmitting area on the array substrate is located within the orthographic projection of the filter layer on the array substrate.

[0010] In the display panel provided in this application, a metal structure is formed within an array substrate, which is used to control the light emission of the light-emitting layer. The light-emitting layer is disposed on one side of the array substrate and is used to emit light for display. At least a portion of the light-emitting layer is located in the display area, and a portion may also be located in the bezel area. A light-filtering layer is located on the side of the light-emitting layer opposite to the array substrate, with a portion of the light-filtering layer located in the bezel area, and this portion located between the light-emitting layer and the encapsulating adhesive. The light-filtering layer is used to filter the light emitted by the light-emitting layer to improve the light emission purity of the display panel. The light-filtering layer can also filter light entering the display panel from the outside, reducing the transmittance and thus reducing the amount of light entering the display panel, thereby reducing the reflectivity of the inner film layer of the display panel. The orthographic projection of the light-filtering layer on the array substrate at least partially overlaps with the orthographic projection of the metal structure on the array substrate. By blocking the metal structure with the light-filtering layer, the probability of external light hitting the metal structure and being reflected and emitted from the light-emitting surface of the display panel can be reduced. The encapsulating adhesive is located on the side of the light filter layer facing away from the array substrate and in the bezel area. The encapsulating adhesive is used to encapsulate the bezel area. The light-shielding layer is located on the side of the encapsulating adhesive facing away from the array substrate and in the bezel area. It is used to shield the bezel area, preventing light reflected from the metal structure of the bezel area from escaping through the light-emitting surface of the display panel. It also shields the encapsulating adhesive, thus preventing the internal structure (including the bezel of the encapsulating adhesive) in the bezel area from being visible from the light-emitting side of the display panel, which would affect the visual effect.

[0011] The display panel provided in this application includes a light-shielding layer comprising a light-shielding area and multiple light-transmitting areas. Forming light-transmitting areas within the light-shielding layer improves light transmittance. By setting the orthographic projection of the light-transmitting area onto the array substrate to fall within the orthographic projection of the encapsulant onto the array substrate, the amount of light (e.g., ultraviolet light) that cures the encapsulant is increased, facilitating curing and improving the curing effect. This addresses the problem of later lifting and detachment caused by poor encapsulant curing, thus improving the curing effect, yield, and overall yield of the display panel's bezel area. Furthermore, by setting the orthographic projection of the light-transmitting area onto the array substrate within the orthographic projection of the filter layer, the filter layer's ability to reduce light transmittance provides supplementary light shielding to the light-transmitting area, improving the reflectivity of the metal structure and further mitigating light leakage at the edge.

[0012] In some embodiments of this application, the ratio of the total area of ​​the light-transmitting area to the total area of ​​the light-shielding layer ranges from 20% to 30%.

[0013] In some embodiments of this application, the light-transmitting area includes a plurality of light-transmitting holes that penetrate the light-shielding layer along the thickness direction of the light-shielding layer, and the plurality of light-transmitting holes are arranged in a dispersed manner.

[0014] In some embodiments of this application, the light-transmitting area further includes a light-transmitting material filling the light-transmitting hole.

[0015] In some embodiments of this application, the light-transmitting material is the same as the encapsulating adhesive.

[0016] In some embodiments of this application, the outer diameter of the light-transmitting hole ranges from 9 μm to 11 μm.

[0017] In some embodiments of this application, the portion of the filter layer located in the frame area includes an opening, and the orthographic projection of the opening on the array substrate does not overlap with the orthographic projection of the light-transmitting area on the array substrate.

[0018] In some embodiments of this application, the filter layer includes filter functional units, and the plurality of filter functional units include a red filter unit, a green filter unit, and a blue filter unit, wherein:

[0019] The portion of the filter layer located in the border area includes either a red filter layer or a blue filter layer.

[0020] In some embodiments of this application, the filter layer includes filter functional units, and the plurality of filter functional units include a red filter unit, a green filter unit, and a blue filter unit, wherein:

[0021] The portion of the filter layer located in the border area includes multiple layers of the filter elements arranged in a direction away from the array substrate, and the multiple layers of the filter elements have different colors.

[0022] In some embodiments of this application, the opening extends through multiple layers of the filter portions arranged in a direction away from the array substrate.

[0023] In some embodiments of this application, the metal structure includes some or all of the metal traces, cathode ring, and metal sealing ring.

[0024] In some embodiments of this application, the display panel further includes a cut-out area located outside the frame area, and the array substrate further includes a test pattern located in the cut-out area;

[0025] The light-shielding layer's orthogonal projection onto the array substrate covers the test pattern.

[0026] In some embodiments of this application, the display panel further includes a filter layer located on the side of the light-emitting layer opposite to the array substrate, and the orthographic projection of the filter layer on the array substrate does not overlap with the cut-out area.

[0027] The second aspect of this application also provides a display device, including any of the display panels provided in the first aspect of this application. Attached Figure Description

[0043] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0044] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0045] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0046] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0047] like Figure 1 and Figure 2 As shown, according to an embodiment of this application, a display panel 1 is provided. The display panel 1 includes a display area A1 and a border area B1 located outside the display area A1. The display panel 1 includes an array substrate 11, a light-emitting layer 12, a light-filtering layer 17, an encapsulant 13, and a light-shielding layer 14. The array substrate 11 includes a metal structure located in the border area B1. The light-emitting layer 12 is located on one side of the array substrate 11. The light-filtering layer 17 is located on the side of the light-emitting layer 12 away from the array substrate 11, and a portion of the light-filtering layer 17 is located in the border area B1. The orthographic projection of the light-filtering layer 17 on the array substrate 11 at least partially overlaps with the orthographic projection of the metal structure on the array substrate 11. The encapsulant 13 is located on the side of the light-filtering layer 17 away from the array substrate 11 and is located in the border area B1. The light-shielding layer 14 is located on the side of the encapsulating adhesive 13 away from the array substrate 11 and is located in the border area B1. The light-shielding layer 14 includes a light-shielding area 141 and a plurality of light-transmitting areas 142. The orthographic projection of the light-transmitting area 142 on the array substrate 11 is located within the orthographic projection of the encapsulating adhesive 13 on the array substrate 11, and the orthographic projection of the light-transmitting area 142 on the array substrate 11 is located within the orthographic projection of the filter layer 17 on the array substrate 11.

[0048] In the display panel 1 provided in this application, a metal structure is formed within an array substrate 11, which is used to control the light emission of the light-emitting layer 12. The light-emitting layer 12 is disposed on one side of the array substrate 11 and is used to emit light for display. The light-emitting layer 12 is at least partially located in the display area A1, and may also be partially located in the border area B1. A light filter layer 17 is located on the side of the light-emitting layer 12 away from the array substrate 11, and a portion of the light filter layer 17 is located in the border area B1, with the portion of the light filter layer 17 in the border area B1 located between the light-emitting layer 12 and the encapsulating adhesive 13. The light filter layer 17 is used to filter the light emitted by the light-emitting layer 12 to improve the light emission purity of the display panel 1. The light filter layer 17 can also filter the light entering the interior of the display panel 1 from the outside, thereby reducing the transmittance and the amount of light entering the display panel 1 from the outside, thus reducing the reflectivity of the inner film layer of the display panel 1. The orthographic projection of the light filter layer 17 onto the array substrate 11 at least partially overlaps with the orthographic projection of the metal structure onto the array substrate 11. By blocking the metal structure with the light filter layer 17, the probability of external light hitting the metal structure and being reflected and escaping from the light-emitting surface of the display panel 1 can be reduced. The encapsulating adhesive 13 is located on the side of the light filter layer 17 away from the array substrate 11 and is located in the bezel area B1. The encapsulating adhesive 13 is used to encapsulate the bezel area B1. The light-shielding layer 14 is located on the side of the encapsulating adhesive 13 away from the array substrate 11 and is located in the bezel area B1. The light-shielding layer 14 is used to block the bezel area B1, preventing the light reflected from the metal structure in the bezel area B1 from escaping from the light-emitting surface of the display panel 1. It can also block the encapsulating adhesive 13, thereby preventing the internal structure (including the bezel of the encapsulating adhesive 13) located in the bezel area B1 from being seen from the light-emitting side of the display panel 1, thus preventing it from affecting the visual effect.

[0049] In the display panel 1 provided in this application, the light-shielding layer 14 includes a light-shielding area 141 and a plurality of light-transmitting areas 142. By forming light-transmitting areas 142 in the light-shielding layer 14, the light transmittance can be improved. By setting the orthogonal projection of the light-transmitting area 142 on the array substrate 11 to be within the orthogonal projection of the encapsulant 13 on the array substrate 11, the amount of light (e.g., ultraviolet light) that cures the encapsulant 13 can be increased, which facilitates the curing of the encapsulant 13 and makes the curing effect of the encapsulant 13 better. This improves the problem of later lifting and falling off caused by poor curing of the encapsulant 13, that is, it improves the curing effect of the encapsulant 13, improves the preparation yield of the encapsulant 13, and improves the yield of the border area B1 of the display panel 1. The orthographic projection of the light-transmitting area 142 on the array substrate 11 is set within the orthographic projection of the filter layer 17 on the array substrate 11. The filter layer 17 can reduce the light transmittance to supplement the light-transmitting area 142, improve the reflectivity of the metal structure to light, and further improve the problem of light leakage in the edge area.

[0050] Specifically, the display panel 1 also includes a glass cover plate 15, which is located on the side of the light-shielding layer 14 facing away from the array substrate 11. When the encapsulant 13 does not cure properly, the encapsulant 13 is prone to lifting and falling off after the display panel 1 is bonded to the glass cover plate 15, resulting in air bubbles in the display panel 1 and affecting the yield of the display panel 1. In this application, by improving the curing yield of the encapsulant 13, defects such as air bubbles in the display panel 1 can be improved, thereby improving the manufacturing yield of the display panel 1.

[0051] Specifically, the light-shielding layer 14 can be formed directly on the edge area of ​​the glass cover plate 15.

[0052] In the above embodiment, the orthogonal projection of the light-shielding layer 14 (including a light-shielding area 141 and multiple light-transmitting areas 142) onto the array substrate 11 can cover the border area B1, thereby improving the light-shielding effect on the border area B1. Figure 2 As shown, the array substrate 11 includes a substrate 111 and a driving circuit layer 112 formed on one side of the substrate 111, in which pixel circuits are formed. The side of the driving circuit layer 112 facing away from the substrate 111 includes a top metal layer 1120, which connects the driving circuit layer 112 to a film layer located on the side of the top metal layer 1120 facing away from the substrate 111. The border region B1 includes a patterned conductive structure, which includes a conductive metal strip 1121 located in the display region A1 and on the top metal layer 1120, metal traces, and conductive traces located in the border region B1. The conductive traces can be arranged around the display region A1 to form a cathode ring 1122. The top metal layer 1120 also includes a metal sealing ring 1123 located in the border region B1 and on the side of the cathode ring 1122 away from the display region A1.

[0053] In the above embodiments, the metal structure is located between the light-emitting layer 12 and the substrate 111. The metal structure includes part or all of the metal traces, cathode ring 1122, and metal sealing ring 1123. The display panel 1 also includes a cathode 24 located on the side of the light-emitting layer 12 facing away from the array substrate 11. The cathode 24 can be connected to the cathode ring 1122 in the frame area B1, and the cathode ring 1122 is used to supply power to the cathode 24. The metal traces are used to realize electrical connections between structures within the driving circuit. The function of the metal sealing ring 1123 is to prevent cracks generated during the cutting process of the array substrate 11 from spreading towards the display area A1 and to provide electrostatic protection. In the above embodiments, the orthogonal projection of the portion of the filter layer 17 located in the frame area B1 onto the array substrate 11 can cover the metal structure to achieve better shielding of the metal structure, thereby further reducing the light leakage rate of the frame area B1 and improving the yield of the display panel 1.

[0054] like Figure 2As shown, the orthographic projection of the encapsulating adhesive 13 on the array substrate 11 is spaced at a preset distance from the display area A1. The display panel 1 also includes a filler adhesive 16 located in the same layer as the encapsulating adhesive 13, with part of the filler adhesive 16 located in the display area A1 and part extending to the border area B1. The encapsulating adhesive 13 is used to block the filler adhesive 16.

[0055] In the above embodiment, the orthogonal projection of the light-transmitting area 142 on the array substrate 1 is located within the orthogonal projection of the encapsulating adhesive 13 on the array substrate 11. On the one hand, the edge of the encapsulating adhesive 13 is covered by the light-shielding area 141 to prevent the edge of the encapsulating adhesive 13 from being observed from the light-emitting side of the display panel 1. On the other hand, the portion of the orthogonal projection of the light-shielding layer 14 on the array substrate 11 that exceeds the orthogonal projection of the encapsulating adhesive 13 on the array substrate 11 is not provided with the light-transmitting area 142. This enables the light-shielding area 141 to effectively shield the area outside the encapsulating adhesive 13 in the frame area B1.

[0056] In one feasible implementation, the ratio of the total area of ​​the light-transmitting area 142 to the total area of ​​the light-shielding layer 14 is in the range of 20%-30%.

[0057] In the above embodiment, the total area of ​​the light-shielding layer 14 is the sum of the total area of ​​the light-shielding area 141 and the total area of ​​the light-transmitting area 142. By controlling the ratio of the total area of ​​the light-transmitting area 142 to the total area of ​​the light-shielding layer 14, the light-shielding effect of the light-shielding area 141 is avoided from being too large, while the light-shielding effect of the light-transmitting area 141 is avoided from being too small, resulting in a small light flux for curing the encapsulating adhesive 13, thus affecting the curing effect of the encapsulating adhesive 13. That is, by setting the ratio of the total area of ​​the light-transmitting area 142 to the total area of ​​the light-shielding layer 14 within the above-mentioned ratio range, both the light-shielding effect of the encapsulating layer 18 and the curing effect of the encapsulating adhesive 13 are taken into account.

[0058] In one feasible implementation, such as Figure 2 and Figure 3 As shown, the light-transmitting area 142 includes a plurality of light-transmitting holes 1410 that penetrate the light-shielding layer 14 along the thickness direction of the light-shielding layer 14, and the plurality of light-transmitting holes 1410 are distributed in a dispersed manner.

[0059] In the above embodiment, the light-transmitting area 142 includes a plurality of dispersed light-transmitting holes 1410, thereby dispersing the area of ​​the light-transmitting area 142 and avoiding the light-transmitting area 142 being too large due to concentrated arrangement, which would affect the light-shielding effect of the light-shielding layer 14 on the frame area B1. Furthermore, the dispersed arrangement of the light-transmitting area 142 can disperse the light transmitted through the light-shielding layer 14 for curing the encapsulating adhesive 13, so that the positions of the encapsulating adhesive 13 receiving light are evenly dispersed, so that each position of the encapsulating adhesive 13 can achieve a good curing effect.

[0060] Specifically, such as Figure 4As shown, the light-transmitting holes 1410 can be arranged in an array, which makes them easy to manufacture.

[0061] Specifically, the spacing between adjacent light-transmitting holes 1410 ranges from 40 μm to 50 μm.

[0062] Specifically, the spacing between adjacent light-transmitting holes 1410 can be 40μm, 41μm, 42μm, 45μm, 48μm, 49μm, 50μm, etc., and this application does not impose any special limitation on it.

[0063] In one feasible implementation, such as Figure 5 As shown, the light-transmitting area 142 also includes a light-transmitting material 1411 filled within the light-transmitting hole 1410.

[0064] In the above embodiment, the light-transmitting area 142 includes a light-transmitting hole 1410 and a light-transmitting material 1411 located within the light-transmitting hole 1410. The light-transmitting material 1411 fills the light-transmitting hole 1410, thereby reducing the step difference in the area of ​​the light-transmitting hole 1410, so as to provide a flat support surface for subsequent film layers, thereby improving the uniformity and stability of the support stress, and thus improving the yield of subsequent film layers.

[0065] In the above embodiments, the light-transmitting material 1411 can be a material with high light transmittance, good flatness, and easy preparation.

[0066] Specifically, the surface of the light-transmitting material 1411 facing away from the array substrate 11 can be flush with the side of the light-shielding area 141 facing away from the array substrate 11, so as to achieve a better support effect for the upper film layer.

[0067] In one feasible implementation, the light-transmitting material 1411 is made of the same material as the encapsulating adhesive 13.

[0068] In the above embodiments, using the same material for the light-transmitting material 1411 and the encapsulating adhesive 13 allows the light used to cure the encapsulating adhesive 13 to propagate within the same material during the process of entering the encapsulating adhesive 13 from the light-transmitting material 1411, thereby resulting in a better curing effect. Furthermore, the material used to prepare the light-transmitting material 1411 can be the same as that used for the encapsulating adhesive 13, eliminating the need to change other materials and simplifying the preparation process.

[0069] In one feasible implementation, the outer diameter of the light-transmitting aperture 1410 ranges from 9 μm to 11 μm.

[0070] Specifically, the outer diameter of the light-transmitting aperture 1410 can be 9μm, 10μm, 11μm, etc., and this application does not make any special limitation on it.

[0071] Specifically, the orthographic projection of the light-transmitting aperture 1410 onto the array substrate 11 is a regular shape such as a circle, polygon, or ellipse, which facilitates fabrication. When it is rectangular, such as... Figure 3 and Figure 4 As shown; when it is circular, as... Figure 6 As shown. The shape of the orthographic projection of the light-transmitting hole 1410 on the array substrate 11 can also be teardrop-shaped, gourd-shaped, etc., and this application does not make any special limitation on this.

[0072] Specifically, polygons can include triangles, squares, rhombuses, rectangles, etc.

[0073] Specifically, the outer diameter of the light-transmitting hole 1410 is the diameter of the circumcircle of the orthogonal projection of the light-transmitting hole 1410 onto the array substrate 11.

[0074] In one feasible implementation, such as Figure 7 As shown, the portion of the filter layer 17 located in the border area B1 includes an opening 170, and the orthographic projection of the opening 170 on the array substrate 11 does not overlap with the orthographic projection of the light-transmitting area 142 on the array substrate 11.

[0075] In the above embodiments, by providing an opening 170 in the edge region of the filter layer 17, the portion of the filter layer 17 located in the border region B1 is made into a patterned structure, thereby achieving diffuse reflection and interception of light, and further improving the light-blocking rate of the border region B1.

[0076] In the above embodiment, multiple openings 170 are arranged in a dispersed manner to better achieve diffuse reflection and interception of light.

[0077] In the above embodiments, such as Figure 8 As shown, the orthographic projection of the opening 170 on the array substrate 11 does not overlap with the orthographic projection of the light-transmitting area 142 on the array substrate 11, thereby causing the light-transmitting area 142 in the light-shielding layer 14 and the opening 170 in the light-filtering layer 17 to be misaligned, so as to achieve complementary light-shielding positions and thus ensure the light-shielding effect.

[0078] In the above embodiments, the shapes of the orthographic projections of different openings 170 on the array substrate 11 can be set to be the same or different, and this application does not make any particular limitation on this.

[0079] In the above embodiments, the orthographic projection of the opening 170 onto the array substrate 11 is a regular shape such as a circle, polygon, or ellipse, which facilitates fabrication. The orthographic projection of the opening 170 onto the array substrate 11 can also be teardrop-shaped, gourd-shaped, etc., and this application does not impose any particular limitation on this.

[0080] Specifically, polygons can include triangles, squares, rhombuses, rectangles, etc.

[0081] In one feasible implementation, such as Figure 7 As shown, the filter layer 17 includes multiple filter functional units, including a red filter unit 171, a green filter unit 172, and a blue filter unit 173, wherein:

[0082] The portion of the filter layer 17 located in the border area B1 includes a red filter layer 171 or a blue filter layer 173.

[0083] In the above embodiments, by forming a light-filtering functional part in the frame area B1, the light-filtering functional part can further block the metal structure, thereby more effectively reducing the reflection of the metal structure.

[0084] In the above embodiments, the display panel 1 may be an OLED display panel 1, and the light-emitting layer 12 may include a red light-emitting functional part, a green light-emitting functional part, and a blue light-emitting functional part. Multiple light-filtering functional parts include a red light-filtering part 171, a green light-filtering part 172, and a blue light-filtering part 173. The red light-filtering part 171 located in the display area A1 corresponds to the red light-emitting functional part; that is, the orthogonal projection of the red light-filtering part 171 onto the array substrate 11 covers the orthogonal projection of the red light-emitting functional part onto the array substrate 11. The green light-filtering part 172 located in the display area A1 corresponds to the green light-emitting functional part; that is, the orthogonal projection of the green light-filtering part 172 onto the array substrate 11 covers the orthogonal projection of the green light-emitting functional part onto the array substrate 11. The blue light-filtering part 173 located in the display area A1 corresponds to the blue light-emitting functional part; that is, the orthogonal projection of the blue light-filtering part 173 onto the array substrate 11 covers the orthogonal projection of the blue light-emitting functional part onto the array substrate 11.

[0085] Specifically, the light-blocking efficiency of the red filter portion 171 and the blue filter portion 173 is higher than that of the green filter portion 172. Therefore, when the portion of the filter layer 17 located in the bezel area B1 includes only one filter functional portion, it can include only the red filter portion 171 or the blue filter portion 173 to improve the light-blocking efficiency of the bezel area B1 and reduce the probability of light reflected from the film layer below the filter layer 17 exiting through the light-emitting surface of the display panel 1, thereby effectively improving the light leakage problem in the bezel area B1 of the display panel 1. Furthermore, when the portion of the filter layer 17 located in the bezel area B1 includes only one filter functional portion, the thickness of the display panel 1 can be reduced, which helps to achieve a thinner and lighter display panel 1.

[0086] In another feasible implementation, such as Figure 9 and Figure 10 As shown, the filter layer 17 includes multiple filter functional units, including a red filter unit 171, a green filter unit 172, and a blue filter unit 173, wherein:

[0087] The portion of the filter layer 17 located in the border area B1 includes multiple filter sections arranged in a direction away from the array substrate 11, and the multiple filter sections have different colors.

[0088] In the above embodiments, by superimposing multiple layers of light-filtering functional units on the border area B1 of the display panel, the light-blocking rate of the border area B1 of the display panel 1 can be improved, and the probability of light reflected from the film layer below the light-filtering layer 17 being emitted through the light-emitting surface of the display panel 1 can be reduced, thereby effectively improving the problem of light leakage in the border area B1 of the display panel 1.

[0089] The multilayer filtering functional unit may include two layers of filtering functional units stacked together. Specifically, it may include a red filter unit 171 and a blue filter unit 173, or it may include a red filter unit 171 and a green filter unit 172, or it may include a blue filter unit 173 and a green filter unit 172.

[0090] The multilayer filtering functional unit may include three layers of filtering functional units stacked together. Specifically, it may simultaneously include a red filter unit 171, a blue filter unit 173, and a green filter unit 172. The vertical positions of the red filter unit 171, the blue filter unit 173, and the green filter unit 172 are not particularly limited in this application. For example: Figure 9 As shown, the multilayer filtering functional unit includes a blue filter unit 173 and a red filter unit 171 sequentially stacked along the direction away from the substrate, or, as... Figure 10 As shown, the multilayer filter functional unit includes a red filter unit 171 and a blue filter unit 173 stacked sequentially along the direction away from the substrate.

[0091] In one feasible implementation, such as Figure 11 As shown, the opening 170 penetrates the multilayer filter section arranged in a direction away from the array substrate 11.

[0092] In the above embodiments, when the portion of the filter layer 17 located in the border region B1 includes multilayer filter functional units stacked along the direction away from the array substrate 11, an opening 170 can be formed on the stacked multilayer filter functional units, and the opening 170 is disposed through the multilayer filter functional units along the stacking direction. By providing the opening 170, the portion of the filter layer 17 located in the border region B1 is made into a patterned structure, thereby achieving diffuse reflection interception of light and further improving the light-shielding rate of the border region B1.

[0093] In the above embodiment, multiple openings 170 are arranged in a dispersed manner to better achieve diffuse reflection and interception of light.

[0094] In the above embodiment, the orthographic projection of the opening 170 on the array substrate 11 and the orthographic projection of the light-transmitting area 142 on the array substrate 11 do not overlap, thereby making the light-transmitting area 142 in the light-shielding layer 14 and the opening 170 in the filter layer 17 misaligned to achieve complementary light-shielding positions, thereby ensuring the light-shielding effect.

[0095] In one feasible implementation, such as Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, the display panel 1 also includes an encapsulation layer 18, which is located on the side of the light-emitting layer 12 facing away from the array substrate 11. Specifically, it may be located on the surface of the cathode 24 facing away from the array substrate 11. The encapsulation layer 18 can encapsulate the light-emitting units within the display panel 1 to prevent damage to the light-emitting units from water / oxygen, etc. The light-emitting unit may include a first electrode located between the array substrate 11 and the light-emitting layer 12, the light-emitting layer 12, and a second electrode located on the side of the light-emitting layer 12 facing away from the array substrate 11. The first electrode may be an anode, and the second electrode may be a cathode. The light-emitting unit may also include a common layer located between the first electrode and the light-emitting layer 12, and between the light-emitting layer 12 and the second electrode. The first electrode may be located on a first conductive layer 19, which is located on the surface of the top metal layer 1120 facing away from the substrate 111.

[0096] The encapsulation layer 18 may include a first encapsulation layer 181, a second encapsulation layer 182, and a third encapsulation layer 183 stacked along a direction away from the array substrate 11. The materials of the first encapsulation layer 181 and the third encapsulation layer 183 may include organic materials, and the material of the second encapsulation layer 182 may include inorganic materials.

[0097] Specifically, the first encapsulation layer 181 may be made of silicon nitride, the second encapsulation layer 182 may be made of aluminum oxide, and the third encapsulation layer 183 may be made of silicon nitride.

[0098] The orthographic projection of the encapsulation layer 18 onto the array substrate 11 covers the array substrate 11.

[0099] The display panel 1 also includes a first planarization layer 20 located on the side surface of the encapsulation layer 18 facing away from the array substrate 11, and the orthographic projection of the first planarization layer 20 on the array substrate 11 covers the array substrate 11.

[0100] In the display panel 1, the filter layer 17 may be located on the side surface of the first planarization layer 20 that is away from the array substrate 11.

[0101] The display panel 1 also includes a second planarization layer 21, which includes an organic layer or two organic layers stacked in a direction away from the array substrate. The second planarization layer 21 is located on the side surface of the filter layer 17 away from the array substrate 11.

[0102] The display panel 1 also includes a light control layer, which can be located on the side surface of the second planarization layer 21 away from the array substrate 11. The light control layer includes optical control units 22 arranged at intervals. The optical control units 22 can control the large-angle light emitted by the light-emitting unit, thereby improving the light output efficiency of the display panel 1.

[0103] In the display panel 1, the encapsulating adhesive 13 has a dimension range of 450μm-750μm along the width direction of the border area B1. The encapsulating adhesive 13 has a dimension range of 9μm-11μm along the thickness direction of the array substrate 11.

[0104] Specifically, the dimensions of the encapsulating adhesive 13 along the width direction of the border region B1 can be 450μm, 500μm, 520μm, 555μm, 593μm, 686μm, 699μm, 700μm, 732μm, 750μm, etc., and this application does not impose any particular limitation thereon. The dimensions of the encapsulating adhesive 13 along the thickness direction of the array substrate 11 can be 9μm, 10μm, 11μm, etc., and this application does not impose any particular limitation thereon.

[0105] In one feasible implementation, such as Figure 1 , Figure 2 , Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, the display panel 1 also includes a cut channel area B2, which is located outside the frame area B1. The array substrate 11 also includes a test pattern (not shown in the figure) located in the cut channel area B2.

[0106] The test pattern is covered by the orthogonal projection of the light-shielding layer 14 onto the array substrate 11.

[0107] In the above embodiment, the cutting zone B2 is provided with a test pattern. The main purpose of the test pattern is to monitor the electrical properties or manufacturing process of the actual panel.

[0108] In the above embodiments, by covering the test pattern with the orthogonal projection of the light-shielding layer 14 on the array substrate 11, the cut-out area B2 of the display panel 1 can be further blocked, that is, the test pattern is prevented from reflecting light and affecting the performance of the display panel 1, the light leakage problem of the cut-out area B2 is improved, and the probability of the user observing light leakage of the cut-out area B2 or observing the test pattern from the light-emitting side of the display panel 1 is reduced.

[0109] In the above embodiments, the display panel 1 further includes a light filter layer 17, which is located on the side of the light-emitting layer 12 away from the array substrate 11. The orthogonal projection of the light filter layer 17 on the array substrate 11 does not overlap with the dicing area B2.

[0110] Specifically, during the fabrication of the filter layer 17, the orthogonal projection of the filter layer 17 onto the array substrate 11 exposes the test pattern, thereby preventing the filter layer 17 from affecting the operation of the test pattern.

[0111] This application also provides a display device 2, such as... Figure 12 As shown, it includes any of the display panels 1 provided in the above embodiments of this application.

[0112] The display device 2 in this application embodiment includes, but is not limited to, mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, control consoles, and other devices with display functions. The edge region fabrication yield of this display device 2 is improved, and edge light leakage is reduced, thereby significantly improving the yield of the display device 2 and enhancing the user experience.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
