Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background Art

[0002] In the prior art, in CFOT (Color Filter On TFE, polarizer-free technology) type display panels, it is often necessary to set up light-transmitting holes in parts of the display panel to cooperate with optical FOD (Fingerprint On Display, under-screen fingerprint recognition technology) or ambient light sensors, etc.; wherein, the light-transmitting holes include openings set in the BM (Black Matrix, light-shielding) layer that penetrate the thickness of its film layer. The existence of such openings will cause the highly reflective cathode set in the film layer below to be exposed, so that the light incident from the openings will be reflected by the highly reflective cathode and then emitted from the openings again, resulting in an increase in the overall reflectivity of the display panel, and further resulting in a deterioration in the display effect of the display panel. Among them, TFE (Thin Film Encapsulastion) refers to thin film encapsulation. Summary of the Invention

[0003] In view of this, the present invention provides a display panel and a display device, which are used to avoid the problem of poor display effect of the display panel when a BM layer is provided with light-transmitting holes.

[0004] In a first aspect, the present application provides a display panel, comprising:

[0005] a substrate, a planar layer located on one side of the substrate, a pixel defining layer located on a side of the planar layer away from the substrate, a first electrode layer located on a side of the pixel defining layer away from the planar layer, and a black matrix layer located on a side of the first electrode layer away from the pixel defining layer;

[0006] The black matrix layer is provided with a first opening;

[0007] The first electrode layer includes a first portion, the first portion overlaps with the first opening, and a surface of the first portion is non-planar.

[0008] In a second aspect, the present application provides a display device, which includes the display panel.

[0009] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0010] The present application provides a display panel and a display device, wherein a black matrix layer of the display panel is provided with a first opening, and a first electrode layer includes a first portion. When the first portion of the first electrode layer and the first opening have an overlapping area, the present application sets the surface of the first portion of the first electrode layer to be non-planar, so that when light incident from the first opening is irradiated on the surface of the first portion, the incident light will not be completely reflected by the first portion to be emitted from the first opening; that is, the present application sets the surface of the first portion of the first electrode layer to be non-planar, and the ambient light entering from the first opening is reflected in different directions by the non-planar first portion, so that a part of the light will be reflected by the surface of the first portion to the surface of the black matrix layer close to the first electrode layer and absorbed by the black matrix layer, thereby reducing or even eliminating the light emitted from the first opening after being reflected by the first portion of the first electrode layer, avoiding the influence of the reflected light on the display effect of the display panel, thereby facilitating improving the display uniformity of the display panel and ensuring user experience.

[0011] Of course, any product implementing the present invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0045] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0046] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0047] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0048] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0049] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0050] In the prior art, in CFOT (Color Filter On TFE, polarizer-free technology) type display panels, it is often necessary to set up light-transmitting holes in parts of the display panel to cooperate with optical FOD (Fingerprint On Display, under-screen fingerprint recognition technology) or ambient light sensors, etc.; wherein, the light-transmitting holes include openings set in the BM (Black Matrix, light-shielding) layer that penetrate the thickness of its film layer. The existence of such openings will cause the highly reflective cathode set in the film layer below to be exposed, so that the light incident from the openings will be reflected by the highly reflective cathode and then emitted from the openings again, resulting in an increase in the overall reflectivity of the display panel, and further resulting in a deterioration in the display effect of the display panel. Among them, TFE (Thin Film Encapsulastion) refers to thin film encapsulation.

[0051] In view of this, the present invention provides a display panel and a display device, which are used to avoid the problem of poor display effect of the display panel when a BM layer is provided with light-transmitting holes.

[0052] Figure 1 FIG. 1 is a top view of a display panel provided in an embodiment of the present application. Figure 2 The embodiment of the present application is shown as follows Figure 1 An enlarged view of area B in the middle. Figure 3 The embodiment of the present application is shown as follows Figure 2 A schematic diagram of the AA' section, Figure 4The embodiment of the present application is shown as follows Figure 2 A schematic diagram of CC' section, please refer to Figure 1-Figure 4 , the present application provides a display panel 100, comprising:

[0053] A substrate 10, a planar layer 11 located on one side of the substrate 10, a pixel defining layer 12 located on a side of the planar layer 11 away from the substrate 10, a first electrode layer 20 located on a side of the pixel defining layer 12 away from the planar layer 11, and a black matrix layer 30 located on a side of the first electrode layer 20 away from the pixel defining layer 12;

[0054] The black matrix layer 30 is provided with a first opening 31;

[0055] The first electrode layer 20 includes a first portion 21 . The first portion 21 overlaps with the first opening 31 , and a surface of the first portion 21 is non-planar.

[0056] The display panel 100 includes a substrate 10, a planar layer 11, a pixel defining layer 12, a first electrode layer 20, and a black matrix layer 30. The black matrix layer 30 includes at least one first opening 31, and the first electrode layer 20 is provided with at least one first portion 21. In the stacking direction of the first electrode layer 20 and the black matrix layer 30, the first portion 21 and the corresponding first opening 31 at least partially overlap. In a cross section perpendicular to the substrate 10 (e.g., Figure 2 In the cross section shown in FIG2 , the at least partial overlap between the first portion 21 and the first opening 31 may include the following situations: the size of the first portion 21 is larger than the size of the first opening 31, or the size of the first portion 21 is equal to the size of the first opening 31, or the size of the first portion 21 is smaller than the size of the first opening 31. When looking down at the display panel, the at least partial overlap between the first portion 21 and the first opening 31 may include the following situations: the contour line of the first portion 21 is located within the contour line of the first opening 31, or the contour line of the first portion 21 coincides with the contour line of the first opening 31, or the contour line of the first portion 21 is located outside the contour line of the first opening 31. The contour line here can be understood as the contour line of the projection pattern of the first portion 21 or the first opening 31 on the plane where the substrate 10 is located.

[0057] In the present application, the surface of the first portion 21 in the first electrode layer 20 is set to be non-planar. The non-planar first portion 21 is used to reflect at least part of the ambient light entering from the first opening 31 in other directions (not toward the first opening 31), so that at least part of the light will be absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first portion 21 of the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0058] The present application uses a non-planar first part 21 to reflect the ambient light entering from the first opening 31 in a specific direction according to a specific rule, so that the light emitted from the first opening 31 after reflection is proportionally reduced, thereby realizing the reflection of the ambient light in a customized direction; therefore, it is possible to reduce or even eliminate the amount of light emitted from the first opening 31 after being reflected by the first part 21 of the first electrode layer 20.

[0059] The display panel 100 includes a plurality of sub-pixels 57 arranged in an array. The present application provides an optional arrangement of the first opening 31, such as Figure 1 As shown, the first opening 31 can be set next to the sub-pixel 57, but does not overlap with the sub-pixel 57. In addition, the first opening 31 can also be set to have an overlapping area with the sub-pixel 57 as required, and this application does not make specific limitations on this.

[0060] It should be noted that "non-planar" can be understood as meaning that the surface of the first portion 21 is not parallel to the plane of the substrate 10, or that the surface of the first portion 21 is not parallel to the plane of the display panel 100, or that when the display panel 100 is placed horizontally, the surface of the first portion 21 is not parallel to the horizontal plane. For example, the surface of the first portion 21 is a curved surface, or the surface of the first portion 21 is an inclined surface, and the angle between the inclined surface and the plane of the substrate 10 is greater than zero. In other words, the first electrode layer 20 includes a portion (the first portion 21) that is not parallel to the plane of the substrate 10.

[0061] It should be noted that the pixel defining layer 12 and the planarizing layer 11 can both be made of organic materials. The pixel defining layer 12 can be formed of organic materials such as polyimide (PI), polyamide, benzocyclobutene (BCB), acrylic resin or phenolic resin, and the planarizing layer 11 can be made of organic resin or photosensitive resin, and specific organic materials include acrylic, polyimide (PI) or benzocyclobutene (BCB).

[0062] The first electrode layer 20 is formed on the surface of the pixel defining layer 12 on the side away from the substrate 10. The first electrode layer 20 can be made by an evaporation deposition process, or the first electrode layer 20 can be made by a sputtering deposition process. The production process of the first electrode layer 20 is located after the pixel defining layer 12. The pixel defining layer 12 includes an opening that defines the light-emitting element. The first electrode layer 20 can cover the position where the opening is set and the position where the opening is not set in the pixel defining layer 12, that is, the entire surface of the first electrode layer 20 is covered on the pixel defining layer 12. When the evaporation deposition process is adopted, the entire surface can be evaporated without using a mask with an array of openings. When the display panel 100 includes a light-emitting element, the relevant production sequence can be: first make the anode, then make the pixel defining layer, then make the light-emitting layer, and then make the first electrode layer and other film structures.

[0063] The thickness of the first electrode layer 20 can range from 50 to 200 nm. It can be seen that the thickness of the first electrode layer 20 is relatively small. Due to the small thickness of the first electrode layer 20, the shape of the surface of the first part 21 away from the substrate 10 side (non-planar) in the present application can also be understood as the shape formed by the first part 21 itself; for example, the non-planar structure of the first part 21 away from the substrate 10 side is the same as its own shape, such as the first part 21 of the first electrode layer 20 as a whole presents a non-planar structure; specifically, for example, the thickness of the first part 21 is equal everywhere, and the first part 21 presents a non-planar side away from the substrate 10.

[0064] The formation of the non-planar first portion 21 of the first electrode layer 20 proposed in this application is achieved by providing at least a portion of the film layer of the display panel 100 located on the side close to the substrate 10 with a specific shape structure, and does not require any adjustment to the manufacturing process of the first electrode layer 20. Figure 3 As shown, the non-planar first portion 21 is formed by being recessed toward the substrate 10 relative to the horizontal portion 27 in the first electrode layer 20; Figure 4 As shown, the non-planar first portion 21 is formed to be concave (also understood as a protrusion) toward the side away from the substrate 10 relative to the horizontal portion 27 in the first electrode layer 20 .

[0065] Figure 5 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of the CC' section, Figure 6 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of the CC' section, Figure 7 The embodiment of the present application is shown as follows Figure 1 A schematic diagram of the D area in the middle, Figure 8 The embodiment of the present application is shown as follows Figure 1 A schematic diagram of the D area, please refer to Figures 1-8 , optionally, the first portion 21 includes a curved surface.

[0066] Specifically, the display panel 100 provided in the present application has a first portion 21 in the first electrode layer 20 that is made non-planar. As described above, the "non-planar" portion includes at least one of a curved surface or an inclined surface, so that the first electrode layer 20 includes a portion (first portion 21) that is not parallel to the plane of the substrate 10. The present application does not specifically limit the number of curved surfaces included in each first portion 21. For example, Figure 3 、 Figure 4 As shown, a first portion 21 may include a curved surface, or may be Figure 5 、 Figure 6As shown, a first portion 21 may include two curved surfaces. Of course, it may also be, for example Figure 7-Figure 8 As shown, a first portion 21 may include three, four, or more curved surfaces, as long as the first portion 21 can be made non-planar. Correspondingly, the present application may choose to have a first opening 31 corresponding to a first portion 21 including one curved surface, or may choose to have a first opening 31 corresponding to a first portion 21 including two, three, or four curved surfaces arranged in two rows and two columns, or have a large curved surface in the middle surrounded by smaller curved surfaces, etc.

[0067] It should also be noted that the present application does not specifically limit the direction of the concave surface. For example, the curved surface can be concave toward the side of the substrate 10 or toward the side of the black matrix layer 30, as long as the first portion 21 can be made non-planar. Furthermore, the present application limits the curvature radius of the curved surface, and users can adjust the setting according to actual needs.

[0068] Please continue to refer to Figures 1-8 , optionally, the curved surface is a spherical surface.

[0069] Specifically, the present application also provides an optional setting method, in which the first part 21 in the first electrode layer 20 is made into a non-planar surface, and the "non-planar surface" here can specifically include a spherical surface when it is set as a curved surface.

[0070] The present application does not impose a specific limit on the number of spherical surfaces included in each first portion 21. For example, a first portion 21 may include one spherical surface, or may include two, three, or more spherical surfaces, as long as the first portion 21 can be made non-planar. Correspondingly, the present application may choose to have one spherical surface in the first portion 21 corresponding to the first opening 31, or may choose to have two, three, or four spherical surfaces arranged in two rows and two columns in the first portion 21 corresponding to the first opening 31, or to have one large spherical surface in the middle surrounded by several smaller spherical surfaces, etc.

[0071] Please refer to Figures 1-6 Optionally, the cross section of the curved surface is a semicircle or a minor arc, and the cross section is perpendicular to the plane where the substrate 10 is located.

[0072] Specifically, when the first portion 21 provided in this application is a curved surface, this application provides an optional configuration in which the cross-section of the curved surface can be a semicircle or a minor arc in a direction perpendicular to the plane of the substrate 10. It should be noted that the semicircle or minor arc cross-section is only one optional embodiment provided in this application and is not limited thereto. Users can select and configure the cross-sectional shape of the curved surface according to their needs.

[0073] Figure 9The embodiment of the present application is shown as follows Figure 1 Another schematic diagram of the D area, please refer to Figures 1-9 Optionally, along the line of sight perpendicular to the plane where the substrate 10 is located, the shape of the first portion 21 is circular or elliptical.

[0074] Specifically, the present application provides an optional configuration in which, along a direction perpendicular to the plane of the substrate 10 (the line of sight), the orthographic projection of the first portion 21 on the plane of the substrate 10 can be circular or elliptical. This allows the cross-section of the first portion 21 to be specifically a curved surface, a spherical surface, a semicircle, a minor arc, etc. The aforementioned configurations of the first portion 21 provided herein result in a non-planar surface on the surface of the first portion 21 in the first electrode layer 20. The non-planar first portion 21 reflects at least a portion of ambient light entering through the first opening 31 in a different direction (not toward the first opening 31), so that at least a portion of the light is reflected from the surface of the first portion 21 onto the surface of the black matrix layer 30 near the first electrode layer 20 and absorbed by the black matrix layer 30. This reduces or even eliminates the light that is reflected by the first portion 21 of the first electrode layer 20 and exits the first opening 31, reducing or preventing the impact of the reflected light on the overall display quality of the display panel 100. This improves the display uniformity of the display panel 100 and ensures and enhances the user experience.

[0075] Figure 10 The embodiment of the present application is shown as follows Figure 1 Another schematic diagram of the D area in the middle, Figure 11 The embodiment of the present application is shown as follows Figure 1 Another schematic diagram of the D area, please refer to Figure 1-Figure 4 、 Figure 10 、 Figure 11 Optionally, the diameter of the circle is greater than or equal to the size of the first opening 31; or

[0076] The major axis of the ellipse is greater than or equal to the size of the first opening 31 .

[0077] Specifically, when the orthographic projection of the first part 21 on the plane where the substrate 10 is located is set to be a circle, and a first opening 31 is only provided with one first part 21, the present application provides an optional setting method, which is to set the diameter of the circle to be larger than the size of the first opening 31, or to set the diameter of the circle to be equal to the size of the first opening 31; or, when the orthographic projection of the first part 21 on the plane where the substrate 10 is located is set to be an ellipse, the present application provides an optional setting method, which is to set the major axis of the ellipse to be larger than the size of the first opening 31, or to set the major axis of the ellipse to be equal to the size of the first opening 31. Such a setting can ensure that when external light is incident on the surface of the first electrode layer 20 from the first opening 31, most or all of the light will be incident on the surface of the first part 21 (the non-planar part of the first electrode layer 20) and will not fall into the planar part of the first electrode layer 20. The non-planar first part 21 reflects at least part of the incident ambient light in a different direction (not toward the first opening 31), so that at least part of the reflected light will be absorbed by the surface of the black matrix layer 30 close to the first electrode layer 20, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first part 21 of the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and helping to ensure and enhance the user experience.

[0078] Please refer to Figure 1-4 、 Figure 10 、 Figure 11 Optionally, the area of ​​the circle is greater than or equal to the area of ​​the first opening 31, and the distance W1 between the two meets the following requirements: greater than or equal to 0 μm and less than or equal to 2 μm; or

[0079] The area of ​​the ellipse is greater than or equal to the area of ​​the first opening 31 , and the distance W2 between the two meets the following conditions: greater than or equal to 0 μm and less than or equal to 2 μm.

[0080] Specifically, when the orthographic projection of the first part 21 on the plane where the substrate 10 is located is a circle, and the orthographic projection of the first opening 31 on the plane where the substrate 10 is located is a circle, the present application provides an optional setting method, which is to set the area of ​​the circular orthographic projection corresponding to the first part 21 to be greater than or equal to the area of ​​the circular orthographic projection corresponding to the first opening 31, and the minimum value range between the edges of the two adjacent circular orthographic projections can be 0-2μm (including the endpoint values), so that the light incident through the first opening 31 can be mostly or even completely irradiated to the surface of the first part 21, and then reflected by the non-planar first part 21, thereby achieving the purpose of reducing the amount of reflected light emitted through the first opening 31, reducing the reflectivity of the display panel 100, and helping to improve the display uniformity of the display panel 100.

[0081] When the orthographic projection of the first part 21 on the plane where the substrate 10 is located is an ellipse, and the orthographic projection of the first opening 31 on the plane where the substrate 10 is located is an ellipse, the present application provides an optional setting method, which is to set the area of ​​the orthographic projection of the ellipse corresponding to the first part 21 to be greater than or equal to the area of ​​the orthographic projection of the ellipse corresponding to the first opening 31; when the major axis directions of the two ellipses are located on the same straight line, the minimum value range between the edges of the adjacent orthographic projections of the two ellipses can be set to 0-2μm (including the endpoint values), so that the light incident through the first opening 31 can be mostly or even completely irradiated to the surface of the first part 21, and then reflected by the non-planar first part 21, thereby achieving the purpose of reducing the amount of reflected light emitted through the first opening 31, reducing the reflectivity of the display panel 100, and helping to improve the display uniformity of the display panel 100.

[0082] Please refer to Figure 1-Figure 3 Optionally, the curved surface includes a first point P, and an angle between a tangent line FF' of the curved surface at the first point P and the plane where the substrate 10 is located is α, α>0;

[0083] The horizontal distances between the first point P and the first opening 31 are V1 and V2 respectively, wherein V1>V2;

[0084] The vertical distance between the first site P and the black matrix layer 30 is H1;

[0085] α≥arctan(V1 / H1)*1 / 2.

[0086] Specifically, the present application provides an optional setting method, in which, when the first part 21 includes a curved surface, it includes a first point P located at any position on the curved surface, and the tangent line FF' passing through the first point P intersects with the extension direction of the plane where the substrate 10 is located, and therefore includes a first angle α. When the value of α is greater than 0, along the direction perpendicular to the plane where the substrate 10 is located, the first point P and the first opening 31 are in the orthographic projection of the plane where the substrate 10 is located. The horizontal distances between the first point P and the edge of the first opening 31 are V1 and V2, where V1 is the largest horizontal distance between the first point P and the edge of the orthographic projection of the first opening 31, and V2 is the smallest horizontal distance between the first point P and the edge of the orthographic projection of the first opening 31; on this basis, along the direction perpendicular to the plane where the substrate 10 is located, the vertical distance between the first point P and the plane where the black matrix layer 30 is located is H1; at this time, the present application provides an optional setting method in which α≥arctan(V1 / H1)*1 / 2. In this way, the ambient light irradiated to the first point P through the first opening 31 can be set. After being reflected by the first part 21, it will not be emitted from the first opening 31, but will be reflected to the surface of the black matrix layer 30 close to the first electrode layer 20, and thus be absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and helping to ensure and enhance the user experience.

[0087] Figure 12 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of CC' section, please refer to Figure 1-Figure 3 、 Figure 12 Optionally, the surface of the first portion 21 includes a concave surface.

[0088] Specifically, the present application provides an optional setting mode in which the surface of the first portion 21 is a concave surface, that is, the cross section of the first portion 21 is a curved surface, or a spherical surface, or a semicircle, or a minor arc, etc. It should be noted that the present application does not specifically limit the concave direction of the concave surface included in the surface of the first portion 21, for example Figure 3 As shown, the concave surface may be formed by being recessed toward one side of the substrate 10, or may be formed by being recessed toward ... Figure 4 As shown, the concave surface is formed by being recessed toward one side of the black matrix layer 30 , as long as the first portion 21 can be made into a non-planar surface.

[0089] Please refer to further Figure 12In addition, the present application also provides an optional setting method, in which the cross-section of the first portion 21 is generally semicircular, but the surface of the semicircle further includes one or more small protrusions 23 and / or one or more small depressions 24; this is equivalent to further forming multiple small curved surfaces on the large curved surface, and the first portion 21 with an uneven surface (non-planar) is used to reflect the ambient light incident from the first opening 31, so that most of the light reflected by the first portion 21 does not exit from the first opening 31, but is reflected to the surface of the black matrix layer 30 close to the first electrode layer 20, and is thereby absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby improving the display uniformity of the display panel 100 and ensuring and enhancing the user experience.

[0090] Figure 13 The embodiment of the present application is shown as follows Figure 1 Another schematic diagram of the D area in the middle, Figure 14 The embodiment of the present application is shown as follows Figure 13 A schematic diagram of the EE' section, please refer to Figure 1 、 Figure 13 、 Figure 14 Optionally, the number of the concave surfaces is at least 2, the joint 56 between adjacent concave surfaces overlaps with the first opening 31 , and the concave surface includes a portion overlapping with the first opening 31 and a portion overlapping with the black matrix layer 30 .

[0091] Specifically, the present application also provides an optional embodiment in which a plurality of concave surfaces are correspondingly provided on the lower side of a first opening 31. For example, two intersecting concave structures can be provided, and a joint portion 56 is included between the two adjacent concave surfaces. The joint portion 56 does not have a large reflective surface (such as Figure 14The present invention provides a method for reducing or eliminating the amount of reflected light reflected from the joint 56 into the first opening 31. The present application proposes that the orthographic projection of the joint 56 on the plane of the substrate 10 be at least partially located within the orthographic projection of the first opening 31 on the plane of the substrate 10, and that the orthographic projection of each of the two concave surfaces on the plane of the substrate 10 overlap with the orthographic projection of the first opening 31 on the plane of the substrate 10, and that the orthographic projection of each of the two concave surfaces on the plane of the substrate 10 overlap with the orthographic projection of the black matrix layer 30 on the plane of the substrate 10. As a result, the area of ​​the two adjacent concave surfaces is slightly larger than that of the first opening 31. This allows the concave surfaces to directionally reflect more light toward areas outside the first opening 31, allowing more reflected light to be absorbed by the black matrix layer 30. This reduces or even eliminates light emitted from the first opening 31 after being reflected by the first electrode layer 20, weakening or avoiding the impact of reflected light on the overall display effect of the display panel 100, thereby further improving the display uniformity of the display panel 100 and ensuring and enhancing the user experience.

[0092] Figure 15 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of the CC' section, Figure 16 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of the CC' section, Figure 17 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of the CC' section, Figure 18 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of CC' section, please refer to Figure 1 、 Figure 2 and Figures 15-18 Optionally, in the first direction, the first portion 21 includes a first side 211 and a second side 212 relative to each other, and along the direction from the first side 211 to the second side 212, the vertical distance P between the first portion 21 and the black matrix layer 30 gradually increases, and the first direction is parallel to the direction of the plane where the substrate 10 is located.

[0093] Specifically, the present application provides a first direction, which is a direction parallel to the plane of the substrate 10. The present application also provides an optional configuration in which the first portion 21 includes a first side 211 and a second side 212 that are arranged opposite each other, wherein the extension direction of the plane in which the first side 211 and the second side 212 are located intersects with the extension direction of the plane in which the substrate 10 is located. Along the direction from the first side 211 to the second side 212, and along the direction perpendicular to the plane in which the substrate 10 is located, the vertical distance P between the first portion 21 and the film layer in which the black matrix layer 30 is located can gradually increase. In other words, the plane in which the first portion 21 is located intersects with the plane in which the substrate 10 is located.

[0094] In other words, the surface of the above-mentioned first part 21 is a bevel, specifically an inclined surface. The setting of the inclined surface can also be used to reflect the ambient light incident from the first opening 31, so that most of the light reflected by the first part 21 will not be emitted from the first opening 31, but will be reflected to the surface of the black matrix layer 30 close to the first electrode layer 20, and thus be absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100, and helping to ensure and enhance the user experience.

[0095] It is also necessary to add that Figure 15 As shown, the cross section of the inclined surface here can be presented as a smooth straight line, or as Figure 16 As shown, it will appear as a curve, and the curved surface may be concave toward the substrate 10 side, or may be as shown in FIG. Figure 17 As shown, it protrudes toward the black matrix layer 30; Figure 18 As shown, a generally smooth straight line may further include a plurality of protrusions 23 and / or depressions 24, a generally curved line that is concave toward the substrate 10 may further include a plurality of protrusions and / or depressions (not shown), and a generally curved line that is convex toward the black matrix layer 30 may further include a plurality of protrusions and / or depressions (not shown). Thus, the first portion 21 formed can be used to reflect ambient light incident from the first opening 31, so that most of the light reflected by the first portion 21 does not exit from the first opening 31, reducing or avoiding the impact of the reflected light on the overall display effect of the display panel 100, thereby improving the display uniformity of the display panel 100 and ensuring and enhancing the user experience.

[0096] Figure 19 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of CC' section, please refer to Figure 1 、 Figure 2 and Figure 19 Optionally, the horizontal dimension of the slope is V3 and the vertical dimension is H2, where V3 <H2。

[0097] Specifically, when the surface of the first part 21 is a slope, in the cross section of the slope in a direction perpendicular to the plane of the substrate 10, the horizontal dimension is V3 and the vertical dimension is H2. The present application provides an optional setting method of V3<H2.

[0098] Since the thickness H2 of the film layer used to form the inclined surface is limited, when the horizontal dimension of the opening is larger, the slope of the inclined surface decreases, and some light will be reflected and transmitted from the first opening 31, which will lead to a decrease in the technical effect; therefore, the present application sets V3<H2, and when the area of ​​the light-transmitting hole (first opening 31) is constant, it can improve the effect of reducing the reflection of external ambient light by the display panel 100.

[0099] Please continue to refer to Figure 1 、 Figure 2 and Figure 19 Optionally, the angle β between the inclined plane and the horizontal plane satisfies [5°, 90°).

[0100] Specifically, when the surface of the first portion 21 includes an inclined surface, the present application provides an optional setting method in which the angle β between the inclined surface and the horizontal plane is greater than or equal to 5° and less than 90°; since when the angle β between the inclined surface and the horizontal plane is set to less than 5°, the angle β between the inclined surface and the horizontal plane will be extremely small, approaching the horizontal setting method in the existing technology. Most of the ambient light entering from the first opening 31 will still be emitted from the first opening 31, and the technical effect of reducing the reflected light emitted from the first opening 31 cannot be achieved; furthermore, if the angle β between the inclined surface and the horizontal plane is 90°, the ambient light entering from the first opening 31 cannot be irradiated onto the surface of the first portion 21, and a vertical structure will be presented between the first portion 21 and the remaining first electrode layers 20. Most of the ambient light entering from the first opening 31 will be irradiated onto the surfaces of the remaining first electrode layers 20 arranged in the horizontal direction, and the number of reflected light emitted from the first opening 31 cannot be reduced.

[0101] In summary, the present application sets the angle β between the inclined plane and the horizontal plane to be greater than or equal to 5° and less than 90°, which can ensure that more incident ambient light is reflected by the first part 21 to the surface of the black matrix layer 30 close to the first electrode layer 20 and absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first part 21 of the first electrode layer 20, avoiding the influence of the reflected light on the display effect of the display panel 100, which is beneficial to improving the display uniformity of the display panel 100 and ensuring user experience.

[0102] Please refer to Figure 1 、 Figure 2 、 Figures 15-19 Optionally, the first electrode layer 20 further includes a second portion 25 and a third portion 26 , the second portion 25 is connected to the first portion 21 at the first side 211 , the third portion 26 is connected to the first portion 21 at the second side 212 , and the height of the second portion 25 is higher than the height of the third portion 26 .

[0103] Specifically, in addition to the above-mentioned inclined surface, the first electrode layer 20 also includes a second portion 25 and a third portion 26. The second portion 25 intersects with the first portion 21 at the first side 211, and the third portion 26 intersects with the first portion 21 at the second side 212. In the direction perpendicular to the plane where the substrate 10 is located, the height of the second portion 25 is higher than the height of the third portion 26, that is, the distance between the second portion 25 and the plane where the substrate 10 is located is greater than the distance between the third portion 26 and the plane where the substrate 10 is located. Furthermore, the second portion 25 and the third portion 26 that are connected to the first portion 21 in the first electrode layer 20 are connected to the first portion 21. The three parts 26 can be arranged on the side of the first part 21 away from the plane where the substrate 10 is located, so that the first part 21 is located at the bottom surface of a recessed surface, so as to reflect the ambient light entering through the first opening 31, so that most of the light can be reflected to the surface of the black matrix layer 30 close to the first electrode layer 20 and absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first part 21 of the first electrode layer 20, avoiding the influence of the reflected light on the display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0104] Figure 20 The figure shows a top view of the first opening provided in the embodiment of the present application, please refer to Figure 1 、 Figure 2 and Figure 20 Optionally, the first opening 31 is in the shape of a strip, the longest dimension of the strip is the second direction, and the second direction intersects with the first direction.

[0105] Specifically, the present application provides an optional configuration in which, in a direction perpendicular to the plane where the substrate 10 is located, the orthographic projection shape of the first opening 31 on the plane where the substrate 10 is located is in addition to Figure 1 、 Figure 2 In addition to the circle shown, it can also be set to a strip shape. The strip here is specifically a rectangle. For example, the aspect ratio of the rectangle can be 3:1 or 5:1, etc., but not 1:1. When the aspect ratio is 1:1, it will be reflected as a square, which is not the strip provided by this application.

[0106] In the present application, the longest dimension direction of the strip may be set as the second direction, wherein the second direction intersects with the first direction, and the first direction is a direction parallel to the plane where the substrate 10 is located.

[0107] Figure 21 The four three-dimensional structural diagrams of the first part provided in the embodiment of this application are shown. Please refer to Figure 1 、 Figures 15-21 Optionally, the first portion 21 includes a first inclined surface 51 and a second inclined surface 52 opposite to each other along the third direction;

[0108] Along the direction from the substrate 10 to the black matrix layer 30 , the first inclined surface 51 and the second inclined surface 52 are inclined in directions away from each other.

[0109] Specifically, the present application provides an optional setting method, for example, when the top view of the first part 21 is a rectangle, the first part 21 includes a first inclined surface 51 and a second inclined surface 52 arranged opposite to each other along a third direction, and the planes where the first inclined surface 51 and the second inclined surface 52 are located intersect with the plane where the substrate 10 is located; along the direction from the substrate 10 to the black matrix, the first inclined surface 51 and the second inclined surface 52 are inclined in directions away from each other, that is, along the direction perpendicular to the plane where the substrate 10 is located, the cross-section of the first part 21 presents a triangular structure; when the first part 21 is formed by the first electrode layer 20 being recessed toward the side of the substrate 10, the cross-section of the first part 21 specifically presents an inverted triangular structure. Specifically, the recess formed by the first part 21 is in the shape of a triangular pyramid or a triangular prism as a whole. The inner surface of the triangular pyramid or the triangular prism is used to reflect the ambient light entering through the first opening 31, so that most of the light can be reflected to the surface of the black matrix layer 30 close to the first electrode layer 20 and absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first part 21 of the first electrode layer 20, avoiding the influence of the reflected light on the display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0110] At the same time, the present application provides an optional setting method, wherein the first part 21 includes a first inclined surface 51 and a second inclined surface 52 arranged opposite to each other along a third direction, and the planes where the first inclined surface 51 and the second inclined surface 52 are located intersect with the plane where the substrate 10 is located. The first part 21 also includes a bottom surface arranged parallel to the plane where the substrate 10 is located, and the first inclined surface 51 and the second inclined surface 52 are both intersected with the bottom surface; along the direction from the substrate 10 to the black matrix layer 30, the first inclined surface 51 and the second inclined surface 52 are inclined in directions away from each other, that is, along the direction perpendicular to the plane where the substrate 10 is located, the cross-section of the first part 21 presents a trapezoidal structure; when the first part 21 is formed by the first electrode layer 20 being recessed toward the side of the substrate 10, the cross-section of the first part 21 specifically presents an inverted trapezoidal structure. Specifically, the depression formed by the first part 21 is in the shape of a "bucket" as a whole. The ambient light entering through the first opening 31 is reflected by the inner surface of the "bucket"-shaped structure, so that most of the light can be reflected to the surface of the black matrix layer 30 close to the first electrode layer 20 and absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first part 21 of the first electrode layer 20, avoiding the influence of the reflected light on the display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0111] Please refer to Figure 1-Figure 4 Optionally, the first electrode layer 20 includes a second portion 27 , the second portion 27 is parallel to the plane where the substrate 10 is located, and the first portion 21 is connected to the second portion 27 ;

[0112] On a plane parallel to the substrate 10 , the area where the first opening 31 is located is within the area where the first portion 21 is located.

[0113] Specifically, the present application also provides an optional setting method, in which the first electrode layer 20 includes a second portion 27, the second portion 27 is parallel to the plane where the substrate 10 is located, and the first portion 21 and the second portion 27 are connected; that is, the first electrode layer 20 includes a planar second portion 27 and a non-planar first portion 21; the present application is set on a plane parallel to the substrate 10, and the orthographic projection of the first opening 31 in the plane is located within the orthographic projection of the first portion 21 in the plane, so that in the corresponding overlapping first portion 21 and the first opening 31, the orthographic projection of the first opening 31 can fall into the first portion The interior of the first portion 21 is formed so that all the ambient light entering through the first opening 31 can fall on the non-plane surface of the first portion 21 and be reflected by the non-plane first portion 21. The non-plane surface is utilized to enable most of the light to be reflected to the surface of the black matrix layer 30 close to the first electrode layer 20 and absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first portion 21 of the first electrode layer 20, avoiding the influence of the reflected light on the display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0114] Please refer to Figure 1-Figure 4 、 Figures 15-18 Optionally, the reflective transmission area 58 is smaller than the area where the first opening 31 is located;

[0115] The reflective transmission area 58 is defined as the incident area corresponding to light that enters the first portion 21 through the first opening 31 and is reflected by the first portion 21 and can then exit through the first opening 31 in a direction perpendicular to the plane of the substrate 10 .

[0116] Specifically, if Figure 3As shown, the present application provides a concept of "reflective transmission area 58". The specific definition of "reflective transmission area 58" is that the incident area corresponding to the light that enters the first portion 21 through the first opening 31 and is reflected by the first portion 21 in a direction perpendicular to the plane where the substrate 10 is located and can be emitted through the first opening 31 after being reflected by the first portion 21. The critical light is illustrated in the figure. For the ambient light incident from the area other than the reflective transmission area 58 of the first opening 31, it will be absorbed by the black matrix layer 30 after being reflected by the first portion 21. The orthographic projection area of ​​the reflective transmission area 58 on the plane where the substrate 10 is located is set to be smaller than the first opening 3 1 on the orthographic projection area of ​​the plane where the substrate 10 is located, thereby reducing the amount of incident light reflected by the first electrode layer 20 out of the first opening 31, thereby further reducing the amount of reflected light reflected by the first electrode layer 20 out of the first opening 31, so that most of the reflected light can be reflected to the surface of the black matrix layer 30 close to the first electrode layer 20 and absorbed by the black matrix layer 30, thereby reducing the light reflectivity of the display panel 100 and weakening the influence of the reflected light on the display effect of the display panel 100, thereby facilitating improving the display uniformity of the display panel 100 and ensuring user experience.

[0117] Please continue to refer to Figure 1-Figure 4 、 Figures 15-18 Optionally, the area of ​​the reflective and transmissive region 58 is less than or equal to 1 / 4 of the area of ​​the region where the first opening 31 is located.

[0118] Specifically, the present application provides an optional setting method in which the area of ​​the reflective and transmissive region 58 is less than or equal to 1 / 4 of the area where the first opening 31 is located, so that the amount of light reflected out of the first opening 31 by the first electrode layer 20 in the display panel 100 is smaller, thereby reducing the reflectivity of the display panel 100.

[0119] However, it should be noted that the "1 / 4" provided above is only an optional embodiment provided by the present application. When the area of ​​the reflective and transmissive region 58 is set to be less than or equal to 1 / 2 or 1 / 3 of the area where the first opening 31 is located, it is also possible to achieve a significant reduction in the amount of light reflected from the first opening 31 by the first electrode layer 20, thereby reducing the reflectivity of the display panel 100 by about 50% or 30%.

[0120] By such a configuration, the amount of incident light reflected out of the first opening 31 by the first electrode layer 20 is reduced, and the amount of reflected light reflected out of the first opening 31 by the first electrode layer 20 is further reduced, so that most of the reflected light can be reflected to the surface of the black matrix layer 30 close to the first electrode layer 20 and absorbed by the black matrix layer 30, thereby reducing the light reflectivity of the display panel 100 and weakening the influence of the reflected light on the display effect of the display panel 100, which is beneficial to improving the display uniformity of the display panel 100 and ensuring user experience.

[0121] Please continue to refer to Figure 1-Figure 4 Optionally, a first recess 123 is provided on a side of the pixel defining layer 12 facing the black matrix layer 30 , and the first portion 21 covers an inner sidewall of the first recess 123 .

[0122] Specifically, the present application provides a setting method for the first part 21, that is, a first recess 123 is set on the surface of the pixel defining layer 12 facing the black matrix layer 30, that is, the pixel defining layer 12 includes a first recess 123 formed on the side facing the substrate 10, and then a first electrode layer 20 is set to cover the inner wall of the first recess 123, forming a first part 21 set on the surface of the first recess 123; that is, relative to the rest of the first electrode layer 20 set on the surface of the pixel defining layer 12, which is a planar structure, a first electrode layer 20 with a non-planar structure, that is, the first part 21, is formed in the first recess 123 of the pixel defining layer 12. By using the non-planar first portion 21, at least part of the ambient light entering from the first opening 31 is reflected in different directions (not toward the first opening 31), so that at least part of the light will be reflected by the non-planar surface to the surface of the black matrix layer 30 close to the first electrode layer 20. The light reflected to the black matrix layer 30 will be absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first portion 21 of the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0123] Figure 22 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of CC' section, please refer to Figure 1 and Figure 22 Optionally, the pixel defining layer 12 is provided with a second opening 128 , and the second opening 128 exposes the planar layer 11 ;

[0124] The first portion 21 covers the sidewall of the second opening 128 and the planar layer 11 exposed by the second opening 128 .

[0125] Specifically, the present application provides an optional configuration in which a second opening 128 is provided in the pixel defining layer 12. The second opening 128 extends through the entire pixel defining layer 12 in a direction perpendicular to the plane of the substrate 10, thereby exposing the planar layer 11 through the second opening 128. The present application provides a first portion 21 covering the sidewalls of the second opening 128 and the planar layer 11 exposed by the second opening 128, so that the non-planar surface formed by the first portion 21 is more obvious, that is, the curvature or tilt angle of the non-planar structure of the first portion 21 is increased, so that the non-planar first portion 21 can reflect more ambient light entering from the first opening 31 in different directions (not toward the first opening 31), so that more light is reflected to the black matrix layer 30 and absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first portion 21 of the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby facilitating improving the display uniformity of the display panel 100 and ensuring user experience.

[0126] As mentioned above, when the cross-section of the curved surface in the first part 21 is a semicircle or a minor arc, it is equivalent to increasing the diameter of the semicircle or the major axis size of the minor arc, thereby increasing the curvature or inclination angle of the non-planar structure of the first part 21.

[0127] It should be noted that the second opening 128 provided in this embodiment does not damage the surface of the flat layer 11, that is, the surface of the flat layer 11 facing the pixel definition layer 12 is still a horizontal plane. The first part 21 in the first electrode layer 20 in this embodiment is only a non-planar structure formed in the film layer structure of the pixel definition layer, but the first part 21 has a contact area with both the pixel definition layer 12 and the flat layer 11.

[0128] It should also be added that when forming a recessed structure in the film layer structure, a halftone mask method can be used; when forming an open hole structure in the film layer structure, an etching method can be used.

[0129] Figure 23 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of the CC' section, Figure 24 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of CC' section, please refer to Figure 1 、 Figure 2 and Figure 23-24 Optionally, a second recess 111 is provided in a portion of the flat layer 11 exposed by the second opening 128 , and the first portion 1 21 covers an inner sidewall of the second recess 111 .

[0130] Specifically, the present application also provides an optional setting method, in which the second opening 128 exposes a portion of the flat layer 11, thereby forming a second recess 111 in the flat layer 11, and the first portion 21 in the first electrode layer 20 covers the inner side wall of the second recess 111, thereby realizing the production of the first portion 21 in the pixel definition layer and the flat layer 11; the non-planar surface formed by the first portion 21 can be made more obvious, that is, the curvature or inclination angle of the non-planar structure of the first portion 21 is increased, and the non-planar first portion 21 can reflect more ambient light entering from the first opening 31 in different directions (not toward the first opening 31), so that more light is reflected to the black matrix layer 30 and absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first portion 21 of the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0131] In addition, the present application does not specifically limit the shape of the second recess 111. It can be a smooth spherical surface, a stepped structure, etc., as long as the recess can be used to form a non-planar first part 21 to reduce the amount of light reflected to the first opening 31.

[0132] Please continue to refer to Figure 1 、 Figure 2 and Figure 23-24 Optionally, the opening of the second opening 128 toward the planar layer 11 is greater than or equal to the opening of the second recess 111 toward the pixel defining layer 12 .

[0133] Specifically, the present application also provides an optional setting method, in which the opening of the second opening 128 toward the flat layer 11 is set to be larger than the opening of the second recess 111 toward the pixel defining layer 12, thereby forming a first part 21 with a stepped cross-section, or the opening of the second opening 128 toward the flat layer 11 is set to be equal to the opening of the second recess 111 toward the pixel defining layer 12, thereby forming a first part 21 with a smooth curved surface (including a spherical surface) or an inclined surface in cross-section; such a setting can realize the production of the first part 21 of the non-planar structure in the pixel defining layer 12 and the flat layer 11, so that the non-planar first part 21 can be used to reflect the light irradiated to its surface, so that more reflected light can be absorbed by the black matrix layer 30, reducing the number of reflected light emitted from the first opening 31, reducing or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0134] Figure 25 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of CC' section, please refer to Figure 1 、 Figure 2 and Figure 25 Optionally, the planar layer 11 includes a first planar layer 112 and a second planar layer 113 that are stacked, and the first planar layer 112 is located on a side of the second planar layer 113 close to the substrate 10;

[0135] The first flat layer 112 is provided with a third recess 114 , the second flat layer 113 is provided with a third opening 115 , and the second recess 111 is composed of the third opening 115 and the third recess 114 .

[0136] Specifically, the present application provides an optional configuration in which the flat layer 11 includes not only one layer, but may include a first flat layer 112 and a second flat layer 113 that are stacked, wherein the first flat layer 112 is located on the side of the second flat layer 113 close to the substrate 10, and when the pixel definition layer 12 includes a first recess 123, a third recess 114 may be further provided in the first flat layer 112, wherein further, a third opening 115 is provided in the second flat layer 113, and the second recess 111 in the flat layer 11 (the first flat layer 112 and the second flat layer 113) is composed of the third opening 115 and the third recess 114; such a configuration can be performed on the surface of the recessed structure formed by the first flat layer 112, the second flat layer 113, and the pixel definition layer. The first part 21 is produced on the surface, which increases the production depth of the first part 21 and can make the non-plane formed by the first part 21 more obvious, that is, the curvature or inclination angle of the non-plane structure of the first part 21 is increased, so that the non-plane first part 21 can reflect the ambient light entering from the first opening 31 more in different directions (not toward the first opening 31), and more light is reflected to the black matrix layer 30 and absorbed by the black matrix layer 30, thereby reducing or even eliminating the light emitted from the first opening 31 after being reflected by the first part 21 of the first electrode layer 20, weakening or avoiding the influence of the reflected light on the overall display effect of the display panel 100, thereby helping to improve the display uniformity of the display panel 100 and ensure user experience.

[0137] Please refer to Figure 1 、 Figure 2 、 Figure 15-17 Optionally, along the first direction, the thickness K of the portion of the planar layer 11 exposed by the second opening 128 gradually decreases.

[0138] Specifically, the present application provides an optional configuration in which the thickness K of the portion of the planar layer 11 exposed by the second opening 128 gradually decreases along the first direction. That is, the cross-section of the structure formed by the second opening 128 in the planar layer 11 presents an inclined surface or an inclined curved surface as described above. The inclined surface or inclined curved surface is used to reflect light that impinges on the first portion 21 disposed on its surface, so that more reflected light can be absorbed by the black matrix layer 30, reducing the amount of reflected light emitted from the first opening 31, and reducing or avoiding the impact of reflected light on the overall display effect of the display panel 100, thereby improving the display uniformity of the display panel 100 and ensuring user experience.

[0139] It should be noted that the flat layer 11 may include only a single flat layer 11 structure, or may include two stacked flat layers 11 structure, for example, a first flat layer 112 and a second flat layer 113, wherein the first flat layer 112 is located on the side of the second flat layer 113 closer to the substrate 10. Therefore, when the first flat layer 112 and the second flat layer 113 are included, the second opening 128 may be formed through at least a portion of the second flat layer 113, or may be formed through the entire second flat layer 113 and through at least a portion of the first flat layer 112. This is not specifically limited in this application, as long as the exposed portion of the second opening 128 can be used to form the non-planar first portion 21.

[0140] It should be added that the thickness K of a single-layer flat layer 11 can be within the range of 1.5μm-2μm; when a plurality of stacked flat layers 11 are included, the thickness K of the entire flat layer 11 can be within the range of 3μm-6μm. If the thickness K of the flat layer 11 is too small, it will be difficult to control during production, and it will be difficult to form a relatively obvious non-planar structure; if the thickness K of the flat layer 11 is too large, it will easily lead to an increase in the thickness K of the entire display panel 100, which is not conducive to the thinning design trend of the display panel 100. However, it should be noted that the above-mentioned setting scheme for the thickness K of the flat layer 11 is only an optional setting range provided by this application, and this application is not limited to this. The user can adjust the production thickness K of the flat layer 11 in the display panel 100 according to actual design requirements.

[0146] Among them, when the first part 21 contacts the pixel defining layer 12, at this time, the present application provides an optional setting method, which is to set the absolute value of the difference between the refractive index of the encapsulation layer 40 and the refractive index of the pixel defining layer 12 to be equal to 0.5, or to set the absolute value of the difference between the refractive index of the encapsulation layer 40 and the refractive index of the pixel defining layer 12 to be less than 0.5; since the first part 21 will be set to a shape including a curved surface, the relationship between the refractive indices of the encapsulation layer 40 and the pixel defining layer 12 is set in this way, so that the shape of the first part 21 will not converge the light of fingerprint retrieval, etc., thereby avoiding affecting the accuracy of fingerprint detection.

[0147] Among them, when the first part 21 is in contact with both the pixel contact layer and the flat layer 11, the present application provides an optional setting method, which is to set the absolute value of the difference between the refractive index of the encapsulation layer 40 and the refractive index of the pixel defining layer 12, and the absolute value of the difference between the refractive index of the encapsulation layer 40 and the refractive index of the flat layer 11 to be equal to 0.5, or to set the absolute value of the difference between the refractive index of the encapsulation layer 40 and the refractive index of the pixel defining layer 12, and the absolute value of the difference between the refractive index of the encapsulation layer 40 and the refractive index of the flat layer 11 to be less than 0.5; since the first part 21 will be set to a shape including a curved surface, the relationship between the refractive indices of the encapsulation layer 40 and the pixel defining layer 12 is set in this way, so that the shape of the first part 21 will not converge the light of fingerprint retrieval, etc., thereby avoiding affecting the accuracy of fingerprint detection.

[0148] The encapsulation layer 40 may include an inorganic layer, an organic layer, or a stacked structure of inorganic layers. For example, the encapsulation layer 40 includes a first encapsulation layer 40, a second encapsulation layer 40, and a third encapsulation layer 40 that are stacked, with the second encapsulation layer 40 being sandwiched between the first encapsulation layer 40 and the third encapsulation layer 40. The first encapsulation layer 40 and the third encapsulation layer 40 are both made of inorganic materials, and the second encapsulation layer 40 is made of an organic material, which may specifically include organic nanoparticles.

The organic material includes polymethyl methacrylate (PMMA) and / or methyl methacrylate (MMA), and the organic nanoparticles include polystyrene-polynitrogen-isopropylacrylamide nanoparticles (PS-PNIPAm NPs) and / or polymethyl methacrylate nanoparticles (PMMA NPs). For example, when the organic material includes polymethyl methacrylate, the organic nanoparticles include polystyrene-polynitrogen-isopropylacrylamide nanoparticles and / or polymethyl methacrylate nanoparticles; when the organic material includes methyl methacrylate, the organic nanoparticles include polymethyl methacrylate nanoparticles.

[0149] It should be added that, in the manufacture of the display panel 100, the inorganic layer in contact with the cathode of the light-emitting element in the display panel 100 can be set to have a refractive index within a range of 1.9-2, so as to make the light emission effect of the light-emitting element more stable and avoid the influence of the inorganic layer on the display effect. However, it should be noted that the above-mentioned range of the refractive index of the inorganic layer in contact with the cathode is only one optional setting range provided by this application, and this application is not limited to this.

[0150] Figure 26 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of CC' section, please continue to refer to Figure 1 、 Figure 26 , Optionally, the material of the pixel defining layer 12 includes a light absorbing material;

[0151] The pixel definition layer 12 defines a second opening 128 , and the second opening 128 does not overlap with the first opening 31 .

[0152] Specifically, the present application also provides an optional configuration in which a second opening 128 is provided in the pixel defining layer 12. Along a direction perpendicular to the plane of the substrate 10, the orthographic projection of the second opening 128 on the plane of the substrate 10 does not overlap with the orthographic projection of the first opening 31 on the plane of the substrate 10. In this case, a light-absorbing material can also be used to make the pixel defining layer 12. The second opening 128 can be used to transmit light signals for detection, such as for applications such as fingerprint recognition and light sensing, or to transmit light from the back side of the display panel 100 to form a transparent display. The second opening 128 can be used to collect oblique light irradiated by the first opening 31, and some of the light can be absorbed by the pixel defining layer 12, reducing the reflectivity of the display panel 100.

[0153] At the same time, when the FOD needs to collect oblique light, the second opening 128, which is offset from the first opening 31, can be used to ensure light transmission. At the same time, the first electrode layer 20 (first portion 21) at the corresponding position of the recessed portion is not parallel to the plane of the substrate 10. After the light is reflected by the first portion 21, the optical path is changed, so that the reflected light is blocked by the black matrix layer 30, reducing the light emitted from the first opening 31 and lowering the reflectivity. It should be noted that the first electrode layer 20 is not provided in the area where the second opening 128 is provided.

[0154] Figure 27 The embodiment of the present application is shown as follows Figure 2 Another schematic diagram of CC' section, please continue to refer to Figure 1 、 Figure 27 , Optionally, the material of the pixel defining layer 12 includes a light absorbing material;

[0155] The pixel definition layer 12 is provided with a fourth opening 129 , and the fourth opening 129 does not overlap with the first opening 31 ;

[0156] A first recess 123 is formed on a side of the pixel defining layer 12 facing the black matrix layer 30 , and the first portion 21 covers an inner sidewall of the first recess 123 .

[0157] Specifically, the present application also provides an optional embodiment, in which a fourth opening 129 is provided in the pixel defining layer 12, and along the direction perpendicular to the plane where the substrate 10 is located, the orthographic projection of the fourth opening 129 on the plane where the substrate 10 is located does not overlap with the orthographic projection of the first opening 31 on the plane where the substrate 10 is located. In this case, a light-absorbing material can also be used to make the pixel defining layer 12; at the same time, a first recess 123 is provided on the side of the pixel defining layer 12 facing the black matrix layer 30, and the first recess 123 is formed by removing part of the thickness of the surface of the pixel defining layer 12 facing the black matrix layer 30, or the first recess 123 is provided by the flat layer 11. Then, when the pixel defining layer 12 is laid on the recess of the flat layer 11, the first recess 123 structure can be naturally formed; and then in the first electrode layer 20 where the pixel defining layer 12 is provided facing the black matrix layer 30, its first part 21 will cover the inner side wall of the first recess 123, thereby forming a non-planar first part 21.

[0158] The fourth opening 129 can be used to transmit optical signals for detection, such as for fingerprint recognition, light sensing, etc., or to transmit light from the back side of the display panel 100 to form a transparent display, etc. The fourth opening 129 can be used to collect oblique light irradiated through the first opening 31, and some of the light can be absorbed by the pixel definition layer 12, thereby reducing the reflectivity of the display panel 100.

[0159] At the same time, when the FOD needs to collect oblique light, the fourth opening set at the position of the first opening 31 can be used to ensure that light passes through. At the same time, the first electrode layer 20 (first part 21) at the corresponding position of the recessed portion is not parallel to the plane of the substrate 10. After the light is reflected by the first part 21, the light path changes, so that the reflected light is blocked by the black matrix layer 30, reducing the light emitted from the first opening 31 and reducing the reflectivity.

[0160] It should be added that the thickness of the first recess 123 may occupy at least part of the thickness of the pixel definition layer, or may occupy the entire thickness of the pixel definition layer. This application does not make any specific restrictions on this, and users can choose according to actual needs.

At this time, the light incident through the first opening 31 will be reflected by the first part 21, and the reflected light will pass through the color resist 60 filled in the first opening 31 and the conventionally set color resist 60, that is, the reflected light will pass through two different color resists 60, and the transmittance of the reflected light will be greatly reduced.

[0171] On this basis, the present application can further configure the sixth opening 62 to be filled with a color resist 60. For the adjacent first opening 31 and sixth opening 62, the colors of the color resist 60 filled in the two are different, so as to achieve a diversified color display through a combination of different colors. Light incident through the first opening 31, after being reflected by the first portion 21, will pass through the color resist 60 filled in the first opening 31 and the color resist 60 filled in the sixth opening 62. That is, the reflected light will pass through two different color resists 60, significantly reducing the transmittance of the reflected light.
