Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically to a display panel and a display device. Background Technology

[0002] Organic light-emitting diode (OLED) display panels are widely used in the field of display technology due to their many advantages, such as active light emission, high contrast, and no viewing angle limitation.

[0003] In OLED display panels, to enhance carrier migration and recombination efficiency, functional layers such as electron transport layers, electron injection layers, hole transport layers, and hole injection layers are typically placed between the electrodes and the light-emitting layer of the OLED device. However, these functional layers usually cover the entire surface of the display panel, encompassing all organic light-emitting devices. During display, in addition to the normal vertical migration of carriers from their respective cathodes and / or anodes to their corresponding light-emitting layers, carriers also migrate laterally between different OLED devices through these functional layers. This lateral leakage can cause crosstalk between different sub-pixels during display, potentially leading to sub-pixels emitting light when not intended to, a phenomenon known as "light leakage," which affects the display quality. Summary of the Invention

[0004] In view of this, the present invention provides a display panel and a display device to solve the above problems.

[0005] In a first aspect, embodiments of the present invention provide a display panel, comprising:

[0006] Substrate;

[0007] Multiple sub-pixels located on the same side of a substrate, the sub-pixels including a first sub-pixel, a second sub-pixel, and a third sub-pixel, the i-th row of sub-pixels including the first sub-pixel and the third sub-pixel alternating along a first direction; the (i+1)-th row of sub-pixels including the second sub-pixel and the third sub-pixel alternating along the first direction; the j-th column of sub-pixels including the first sub-pixel and the third sub-pixel alternating along a second direction; the (j+1)-th column of sub-pixels including the second sub-pixel and the third sub-pixel alternating along the second direction; at least one of the first sub-pixel, the second sub-pixel, and the third sub-pixel has a circular shape;

[0008] Multiple color resist layers located on the side of the sub-pixel away from the substrate, the color resist layers include a first color resist layer, a second color resist layer and a third color resist layer, along a direction perpendicular to the plane where the substrate is located, the first color resist layer overlaps at least partially with the first sub-pixel, the second color resist layer overlaps at least partially with the second sub-pixel, and the third color resist layer overlaps at least partially with the third sub-pixel.

[0009] Multiple partitions, each partition partially surrounding a sub-pixel, at least one partition including a notch.

[0010] Secondly, embodiments of the present invention provide a display device including the aforementioned display panel.

[0011] The display panel and display device provided in this embodiment of the invention can improve the accuracy of the emitted color of the sub-pixels and improve the light emission effect of the display panel by setting a resistive layer on the side of the sub-pixels away from the substrate. On the other hand, it can also reduce the reflectivity of the display panel and reduce the interference of ambient light on the light emission of the display panel.

[0012] Moreover, this configuration eliminates the need for an additional polarizing layer in the display panel, which helps reduce the panel's thickness. Furthermore, by including circular sub-pixels in the display panel, this embodiment of the invention reduces the risk of diffraction effects during light emission, avoids surface stripes, and improves the light emission performance of the sub-pixels, thus enhancing the visual appeal of the display panel.

[0013] Furthermore, by providing a partition around the sub-pixels, this embodiment of the invention helps to block or extend the path of lateral leakage current transmission through the common layer between adjacent sub-pixels, thereby suppressing the transmission of lateral leakage current. Moreover, by providing a notch in the partition, this embodiment of the invention allows the second electrode to be formed into a continuous structure with a larger thickness at the notch, ensuring the overall continuity of the second electrode, reducing the risk of breakage or thinning of the second electrode, and improving the operational stability of the display panel.

[0033] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0036] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0037] This invention provides a display panel, combined with Figure 1 and Figure 2 As shown, Figure 1 This is a top view schematic diagram of a display panel provided in an embodiment of the present invention. Figure 2 This is a cross-sectional schematic diagram of a display panel provided in an embodiment of the present invention. The display panel 100 includes a substrate 10 and a plurality of sub-pixels 20 located on the same side of the substrate 10. The plurality of sub-pixels 20 includes a first sub-pixel 201, a second sub-pixel 202, and a third sub-pixel 203. Optionally, the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 are sub-pixels of three different colors, such as a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

[0038] Continue to refer to Figure 1 As shown, in the display panel 100, the i-th row sub-pixel i20 includes a first sub-pixel 201 and a third sub-pixel 203 alternating along the first direction X1, and the (i+1)-th row sub-pixel (i+1)-th row sub-pixel (i+1)-th row sub-pixel (i+1)-th row sub-pixel (j ...

[0039] Optional, such as Figure 2As shown, the display panel 100 also includes an encapsulation layer 11, a black matrix BM, and multiple color resist layers 30 located on the side of the sub-pixel 20 away from the substrate 10. The black matrix BM may be located on the side of the encapsulation layer 11 away from the substrate 10, and the black matrix BM includes an opening. The color resist layers 30 are at least partially located within the opening of the black matrix BM. Light emitted from the sub-pixel 20 passes through the color resist layers 30 before exiting, which can improve the accuracy of the emitted color of the sub-pixel 20.

[0040] For example, when the sub-pixels 20 are set as first sub-pixels 201, second sub-pixels 202 and third sub-pixels 203 with different emitted light colors, the color resist layer 30 includes a first color resist layer 301, a second color resist layer 302 and a third color resist layer 303. Along the direction perpendicular to the plane of the substrate 10, the first color resist layer 301 overlaps at least partially with the first sub-pixel 201, the second color resist layer 302 overlaps at least partially with the second sub-pixel 202, and the third color resist layer 303 overlaps at least partially with the third sub-pixel 203.

[0041] Furthermore, the color resist layer 30 can also reduce the reflectivity of the display panel 100 by absorbing incident ambient light. Moreover, based on this arrangement, the color resist layer 30 is essentially reused as a polarizer, thus eliminating the need for an additional polarizer on the light-emitting side of the display panel 100, which helps to reduce the thickness of the display panel 100.

[0042] For example, at least one of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 has a circular shape. Figure 2 As shown, the display panel 100 also includes a pixel definition layer 50, which includes a pixel opening 501. At least a portion of the sub-pixel 20 is formed in the pixel opening 501, and the shape of the sub-pixel 20 is the same as the shape of the pixel opening 501. In this embodiment of the invention, at least one of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 has a circular shape; that is, the shape of the pixel opening where at least one of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 is located is circular.

[0043] In related technologies, subpixels are typically square or polygonal with well-defined equilateral corners. To reduce ambient light reflection and achieve a seamless black effect on the display panel, a black matrix (BM) is usually fabricated between adjacent subpixels. The black matrix BM is located on the light-emitting side of the subpixel 20, and the shape of the opening in the black matrix BM follows the shape of the subpixel. When a black matrix BM is fabricated between adjacent square subpixels, the light emitted by the subpixel through the opening in the black matrix BM is equivalent to passing through a slit, resulting in a diffraction effect. This causes a series of alternating bright and dark stripes on the light-emitting surface of the display panel, affecting the display effect.

[0044] In this embodiment of the invention, by making at least one of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 circular in shape, when setting the black matrix BM, the shape of the opening set in the corresponding sub-pixel 20 in the black matrix BM can also be circular, which can reduce the probability of diffraction effect when the sub-pixel 20 emits light, avoid the appearance of stripes on the surface of the display panel 100, and improve the visual effect of the display panel 100.

[0045] It should be noted that, considering process errors, the circular shape of the sub-pixel 20 can be a circle within the allowable range of process errors. For example, the actual shape of the sub-pixel 20 can be a shape similar to a standard circle.

[0046] For example, such as Figure 2 As shown, the encapsulation layer 11 includes a first encapsulation layer 111, a second encapsulation layer 112, and a third encapsulation layer 113 stacked together. For example, the first encapsulation layer 111 and the third encapsulation layer 113 may include inorganic encapsulation layers, and the second encapsulation layer 112 may include organic encapsulation layers.

[0047] Continue to refer to Figure 1 As shown, the display panel 100 also includes a plurality of partitions 40, which partially surround the sub-pixels 20 and are located between adjacent sub-pixels 20. At least one partition 40 includes a notch 40A.

[0048] For example, such as Figure 2 As shown, the sub-pixel 20 includes a first electrode 20A, a light-emitting layer 20B, a second electrode 20C, and a common layer 20D. The partition portion 40 is located on the side of the common layer 20D closest to the substrate 10. Optionally, the common layer 20D includes a first sub-common layer 20D1 and a second sub-common layer 20D2, where the first sub-common layer 20D1 is located between the first electrode 20A and the light-emitting layer 20B, and the second sub-common layer 20D2 is located between the second electrode 20C and the light-emitting layer 20B.

[0049] In this embodiment of the invention, the pixel opening 501 of the pixel definition layer 50 exposes at least a portion of the first electrode 20A. The first electrodes 20A of different sub-pixels 20 are independent of each other, and the second electrodes 20C of multiple sub-pixels 20 are electrically connected to each other. Optionally, the first electrode 20A includes an anode, and the second electrode 20C includes a cathode. The first sub-common layer 20D1 includes a hole injection layer and / or a hole transport layer. The second sub-common layer 20D2 includes an electron injection layer and / or an electron transport layer.

[0050] In this embodiment of the invention, combined with Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, Figure 3 , Figure 4 and Figure 5 The diagram shows a cross-sectional view of three other display panels provided in the embodiments of the present invention. The partition 40 includes at least one of a first sub-partition 40C1 and a second sub-partition 40C2.

[0051] Among them, such as Figure 2 and Figure 3 As shown, the first sub-partition 40C1 includes a protrusion 401 that protrudes toward the side away from the substrate 10. For example, the surface of the protrusion 401 away from the substrate 10 may extend beyond the pixel definition layer 50 to form a protrusion toward the light-emitting surface of the display panel 100.

[0052] like Figure 4 and Figure 5 As shown, the second sub-partition 40C2 includes a recessed portion 402 recessed on one side facing the substrate 10. Optionally, in embodiments of the present invention, the recessed portion 402 may be formed in the pixel definition layer 50 described above.

[0053] For example, such as Figure 2 and Figure 3 As shown, the protrusion 401 includes a first side surface S11 and a first bottom surface S12 on the side close to the substrate 10.

[0054] Optional, such as Figure 2 As shown, in this embodiment of the invention, the included angle between the first side surface S11 and the first bottom surface S12 facing inward toward the protrusion 401 can be an acute angle, that is, the area of ​​the side of the protrusion 401 away from the substrate 1 is smaller than the area of ​​the side closer to the substrate 1. Based on this arrangement, the common layer 20D formed after the protrusion 401 can be formed on the first side surface S11, which can extend the path of lateral leakage current transmission through the common layer 20D between two adjacent sub-pixels 2, thereby suppressing the transmission of lateral leakage current and improving the display effect.

[0055] Or, such as Figure 3 As shown, in this embodiment of the invention, the included angle between the first side surface S11 and the first bottom surface S12 facing inward toward the protrusion 401 can be an obtuse angle. That is, the area of ​​the side of the protrusion 401 away from the substrate 10 is larger than the area of ​​the side closer to the substrate 10. Based on this arrangement, the common layer 20D formed after the protrusion 401 cannot be formed on the first side surface S11 and is thus broken at the protrusion 401. This can block the path of lateral leakage current through the common layer 20D between two adjacent sub-pixels 20, thereby suppressing the transmission of lateral leakage current and improving the display effect.

[0056] Optional, such as Figure 4 and Figure 5 As shown, the recessed portion 402 includes a second side surface S21 and a second bottom surface S22 on the side close to the substrate 10.

[0057] like Figure 4 As shown, the angle between the second side surface S21 and the second bottom surface S22 can be an obtuse angle. Based on this arrangement, the common layer 20D, which is formed after the recessed portion 402, is formed on the second side surface S21 of the recessed portion 402. Based on the morphological characteristics of the recessed portion 402, it is beneficial to extend the path of lateral leakage current transmission through the common layer 20D between two adjacent sub-pixels 20, thereby suppressing the transmission of lateral leakage current and improving the display effect.

[0058] Or, such as Figure 5 As shown, the angle between the second side surface S21 and the second bottom surface S22 can also be set to an acute angle so that the common layer 20D formed after the recess 402 cannot be formed on the second side surface S21 and is thus broken at the recess 402, thereby blocking the path of lateral leakage current through the common layer 20D between two adjacent sub-pixels 20, thereby suppressing the transmission of lateral leakage current and improving the display effect.

[0059] The present invention provides an embodiment of the invention that includes at least one of a first sub-partition 40C1 and a second sub-partition 40C2 in the partition portion 40. This is beneficial to improving the structural diversity of the prepared partition portion 40 and to preparing the first sub-partition 40C1 and the second sub-partition 40C2 according to the structural morphology between adjacent sub-pixels 20, thereby improving the application effect of the partition portion 40 in improving lateral leakage.

[0060] In this embodiment of the invention, the partition portion 40 partially surrounds the sub-pixel 20, which is beneficial to extend the length of the above-mentioned common layer 20D laid between adjacent sub-pixels 20 in multiple directions, extend the transmission path of leakage current between two adjacent sub-pixels 20 in multiple directions, and reduce the risk of leakage current between adjacent sub-pixels 20.

[0061] In embodiments of the present invention, such as Figure 1 As shown, at least one partition portion 40 includes a notch 40A, that is, at least one partition portion 40 is a non-closed pattern including a notch 40A. When the partition portion 40 is configured to include... Figure 2 or Figure 3 The protrusion 401 shown, or, Figure 4 or Figure 5 When the recessed portion 402 is shown, the partition portion 40 includes a notch 40A, which means that the partition portion 40 at the location of the notch 40A is an approximately flat structure that does not include the aforementioned protrusion and recess.

[0062] The notch 40A can prevent the second electrode 20C, which is formed after the partition 40, from being broken or thinned at the notch 40A. The second electrode 20C is a continuous structure fabricated between adjacent sub-pixels 20. When the second electrode 20C is fabricated, it will follow the shape and structure of the partition 40 and have a vertical climbing structure.

[0063] In related technologies, there may be cases where the second electrode 20C is disconnected or thinned at the partition 40, resulting in significant differences in the resistance of the second electrode 20C at different positions of the display panel 100, and the second electrode 20C at some positions may be disconnected and fail.

[0064] Based on the method provided in the embodiments of the present invention, a notch 40A is prepared at the partition portion 40, making the notch 40A a smooth surface (this surface can be the surface of the pixel definition layer 50 facing the light-emitting surface of the display panel 100). This can ensure that the structure of the subsequently prepared second electrode 20C at the notch 40A is relatively regular and smooth, reducing the risk of the second electrode 20C breaking or thinning at the notch 40A. This is beneficial to ensuring the continuity of the second electrode 20C between adjacent sub-pixels 20, making the second electrode 20C form a continuous structure with a large thickness at the notch 40A, reducing the voltage drop of the signal transmitted by the second electrode 20C during transmission, and improving the voltage uniformity of the second electrode 20C in the display area.

[0065] Optional, such as Figure 1 As shown, at least one of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 corresponds to a partition portion 40 including two notches 40A. As mentioned above, the second electrode 20C can form a relatively flat and continuous structure with a certain thickness at the notch 40A; that is, at the notch 40A, the second electrode 20C does not include a significant vertical climbing structure. By including two notches 40A in the partition portion 40 corresponding to at least one of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203, this embodiment of the invention increases the number of continuous structures in the second electrode 20C, which helps to further reduce the risk of structural breakage or thinning when the second electrode 20C is continuously fabricated between adjacent sub-pixels 20.

[0066] Optional, combined Figure 1 and Figure 6 As shown, Figure 6 for Figure 1 An enlarged schematic diagram of the central region E1 shows that the line connecting the center C of the two notches 40A passes through the centroid G of the orthographic projection of the corresponding sub-pixel 20 onto the plane of the substrate 10.

[0067] like Figure 6As shown, the partition 40 includes a first endpoint D1 and a second endpoint D2, and the gap 40A is located between the first endpoint D1 and the second endpoint D2. The midpoint of the line connecting the first endpoint D1 and the second endpoint D2 is the center C of the gap 40A.

[0068] It is understood that the centroid G of the orthographic projection of sub-pixel 20 onto the plane of substrate 10 mentioned in this embodiment of the invention can be defined as the center point of the mass distribution of the orthographic projection of sub-pixel 20 onto the plane of substrate 10, i.e., the centroid. If the geometry of the orthographic projection of sub-pixel 20 onto the plane of substrate 10 is a regular geometry, then the geometric center of the orthographic projection of sub-pixel 20 onto the plane of substrate 10 coincides with its centroid. For example, if the shape of the orthographic projection of sub-pixel 20 onto the plane of substrate 10 is a circle, the center of the circle is both its geometric center and its centroid. If the geometry of the orthographic projection of sub-pixel 20 onto the plane of substrate 10 is an asymmetrical irregular geometry, then its centroid can be determined by related techniques, but its geometric center is more difficult to determine. In this case, the relative positional relationship between the geometric center and the centroid of the orthographic projection of sub-pixel 20 onto the plane of substrate 10 is difficult to determine.

[0069] It should be noted that the regular shapes (regular geometric shapes) in this invention satisfy at least one of the following conditions: 1) centrally symmetric shapes; 2) axially symmetric shapes with two or more axes of symmetry. Examples of regular shapes include ellipses, parallelograms (neither rectangles nor rhombuses), circles, rounded rectangles, regular polygons, rectangles, and rhombuses. For centrally symmetric shapes, the central point of symmetry is the center (centroid); for axially symmetric shapes with two or more axes of symmetry, the intersection of the two axes of symmetry is the center (centroid). Shapes other than regular shapes are considered irregular shapes.

[0070] For example, such as Figure 6 As shown, the center of gravity G of sub-pixel 20 is located on the line connecting the centers of the two gaps 40A of the corresponding partition 40. Optionally, in circular sub-pixel 20, the center of gravity of sub-pixel 20 can be the midpoint of the line connecting the centers of the two gaps 40A.

[0071] In this embodiment of the invention, the line connecting the centers C of the two notches 40A passes through the centroid G of the orthographic projection of the corresponding sub-pixel 20 onto the plane of the substrate 10. This allows the two notches 40A surrounding the same sub-pixel 20 to be located at two mutually symmetrical positions on the sub-pixel 20. On the one hand, this can improve the structural uniformity of the second electrode 20C corresponding to the sub-pixel 20. On the other hand, it can also increase the distance between the two notches 40A. If leakage occurs at the notch 40A, this method can make the leakage path as dispersed as possible, which is beneficial to improving display uniformity.

[0072] Optional, such as Figure 6As shown, the partition portion 40 includes: a first partition portion 40B1, which at least partially surrounds the first sub-pixel 201, and the first partition portion 40B1 includes a first notch 40A1; a second partition portion 40B2, which at least partially surrounds the second sub-pixel 202, and the second partition portion 40B2 includes a second notch 40A2; and a third partition portion 40B3, which at least partially surrounds the third sub-pixel 203, and the third partition portion 40B3 includes a third notch 40A3.

[0073] Optionally, in an embodiment of the present invention, at least two of the orientations of the first notch 40A1, the second notch 40A2, and the third notch 40A3 are not parallel to each other.

[0074] The orientation of the notch 40A in the partition 40 refers to the direction from the centroid G of the orthographic projection of the sub-pixel 20 corresponding to the partition 40 onto the plane of the substrate 10 to the center C of the notch 40A. The center C of the notch 40A refers to the midpoint of the line connecting the two endpoints of the partition 40 forming the notch 40A. Figure 6 As shown, the partition 40 includes a first endpoint D1 and a second endpoint D2. The first endpoint D1 and the second endpoint D2 are located on both sides of the same gap 40A. The midpoint of the line connecting the first endpoint D1 and the second endpoint D2 is the center C of the gap 40A.

[0075] Figure 6 The first arrow A1 indicates the location of one of the first gaps 40A1 in the first partition 40B1, the second arrow A2 indicates the location of one of the second gaps 40A2 in the second partition 40B2, and the third arrow A3 indicates the location of one of the third gaps 40A3 in the third partition 40B3.

[0076] For example, such as Figure 6 As shown, in embodiments of the present invention, the orientation of the first notch 40A1 can be made non-parallel to the orientation of the second notch 40A2; or, as... Figure 6 As shown, the orientation of the first gap 40A1 can also be made non-parallel to the orientation of the third gap 40A3; or, as... Figure 7 As shown, Figure 7 This is a partially enlarged schematic diagram of another display panel provided in an embodiment of the present invention. In this embodiment of the present invention, the orientation of the second notch 40A2 may not be parallel to the orientation of the third notch 40A3.

[0077] Optionally, at least two of the orientations of the first gap 40A1, the second gap 40A2, and the third gap 40A3 may intersect or be perpendicular to each other.

[0078] Optional, such as Figure 6 and Figure 7As shown, the orientations of the first notch 40A1 and the second notch 40A2 are not parallel to each other. An angle α, 0 < α < 180°, is formed between the direction of the first arrow A1 and the direction of the second arrow A2. This increases the distance between the first notches 40A1 and 40A2 corresponding to adjacent first sub-pixels 201 and 202, thereby increasing the lateral leakage path between the first sub-pixels 201 and 202 and ensuring the light emission stability of the first sub-pixels 201 and 202.

[0079] For example, in embodiments of the present invention, 0°≤α≤90° can be set, for example, 30°≤α≤60° can be set, for example, α=45° can be set.

[0080] Optional, such as Figure 6 and Figure 7 As shown, in this embodiment of the invention, the orientations of the first notch 40A1 and the second notch 40A2 can be made perpendicular to each other. That is, the angle α between the direction of the first arrow A1 and the direction of the second arrow A2 is 90°. Based on this arrangement, for multiple second sub-pixels 202 located around the same first sub-pixel 201, the notch 40A corresponding to the first sub-pixel 201 can have a large distance from the notches 40A of the multiple second sub-pixels 202, thereby reducing the leakage current effect between the first sub-pixel 201 and the multiple second sub-pixels 202 located around it. Similarly, the leakage current effect between the second sub-pixel 202 and the multiple first sub-pixels 201 located around it can also be reduced.

[0081] Optional, such as Figure 7 As shown, in this embodiment of the invention, the orientations of the second notch 40A2 and the third notch 40A3 can be made non-parallel. An angle β is formed between the direction of the second arrow A2 and the direction of the third arrow A3, where 0° < β < 180°. This increases the distance between the second notch 40A2 and the third notch 40A3 corresponding to the adjacent second sub-pixel 202 and third sub-pixel 203, thereby extending the lateral leakage path between the second sub-pixel 202 and the third sub-pixel 203 and ensuring the light emission stability of the second sub-pixel 202 and the third sub-pixel 203.

[0082] For example, in embodiments of the present invention, 90°≤β≤180° can be set, for example, 120°≤β≤150° can be set, for example, β=135° can be set.

[0083] Optional, such as Figure 8 As shown, Figure 8This is a partially enlarged schematic diagram of another display panel provided in an embodiment of the present invention, wherein the orientation of the second notch 40A2 and the orientation of the third notch 40A3 are perpendicular to each other, that is, the angle β between the directions of the second arrow A2 and the third arrow A3 is 90°. Based on this arrangement, for multiple second sub-pixels 202 located around the same third sub-pixel 203, the notch 40A corresponding to the third sub-pixel 203 can have a large distance from the notches 40A of the multiple second sub-pixels 202, thereby reducing the leakage current effect between the third sub-pixel 203 and the multiple second sub-pixels 202 located around it. Similarly, the leakage current effect between the second sub-pixel 202 and the multiple third sub-pixels 203 located around it can also be reduced.

[0084] Optional, such as Figure 6 and Figure 7 As shown, in this embodiment of the invention, the orientations of the first notch 40A1 and the third notch 40A3 can be made non-parallel. For example... Figure 6 and Figure 7 As shown, the first arrow A1 indicates the orientation of the first notch 40A1 of the first partition 40B1, and the third arrow A3 indicates the orientation of the third notch 40A3 of the third partition 40B3. An angle γ, 0° < γ < 180°, is formed between the directions of the first arrow A1 and the third arrow A3. This increases the distance between the first notch 40A1 and the third notch 40A3 corresponding to the adjacent first sub-pixel 201 and third sub-pixel 203, thereby extending the lateral leakage path between the first sub-pixel 201 and the third sub-pixel 203, improving light leakage, and ensuring the light output stability of the first sub-pixel 201 and the third sub-pixel 203.

[0085] For example, in embodiments of the present invention, 0°≤γ≤90° can be set, for example, 30°≤γ≤60° can be set, for example, γ=45° can be set.

[0086] Optional, such as Figure 6 As shown, in this embodiment of the invention, the orientation of the first notch 40A1 and the orientation of the third notch 40A3 can be made perpendicular to each other, that is, the angle γ between the directions of the first arrow A1 and the third arrow A3 is 90°. Based on this arrangement, for multiple first sub-pixels 201 located around the same third sub-pixel 203, the notch 40A corresponding to the third sub-pixel 203 can have a large distance from the notches 40A of the multiple first sub-pixels 201, thereby reducing the leakage current effect between the third sub-pixel 203 and the multiple first sub-pixels 201 located around it. Similarly, the leakage current effect between the first sub-pixel 201 and the multiple third sub-pixels 203 located around it can also be reduced.

[0087] Optional, such as Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment of the invention, the distance between the two endpoints of at least two notches 40A corresponding to the same sub-pixel 20 can be made equal to improve the structural consistency among multiple notches 40A, thereby improving the efficiency of notch 40A preparation and also helping to improve the structural uniformity of the prepared second electrode 20C, ensuring that the structural thickness and shape of the second electrode 20C are similar at multiple notches 40A.

[0088] In another alternative implementation, such as Figure 9 As shown, Figure 9 This is a partially enlarged schematic diagram of another display panel provided in an embodiment of the present invention. The partition portion 40 includes a second partition portion 40B2 that at least partially surrounds the second sub-pixel 202. The second partition portion 40B2 includes at least two second notches 40A2. In this embodiment of the present invention, the distance between the two endpoints of the at least two second notches 40A2 is different, so that the sizes of the at least two second notches 40A2 are different. By differentiating the two second notches 40A2 in the second partition portion 40B2, this embodiment of the present invention allows for the preparation of second notches 40A2 of different sizes based on their positions, such as the distance between each second notch 40A2 and adjacent sub-pixels, during the design process of the display panel. This makes the design of the second notches 40A2 more flexible and also makes full use of the positional characteristics of the second notches 40A2.

[0089] In another optional embodiment, the present invention may also make the distance between the two endpoints of the at least two first notches 40A1 included in the first partition portion 40B1 different, or make the distance between the two endpoints of the at least two third notches 40A3 included in the third partition portion 40B3 different.

[0090] Optional, such as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment of the invention, a plurality of third sub-pixels 203 can form a first virtual trapezoid M1, the centers of the plurality of third sub-pixels 203 are respectively located at the vertices of the first virtual trapezoid M1, and the first sub-pixel 201 or the second sub-pixel 202 is located inside the first virtual trapezoid M1.

[0091] For example, such as Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the first virtual trapezoid M1 may include a first sub-virtual trapezoid M11 and a second sub-virtual trapezoid M12, wherein the first sub-virtual trapezoid M11 may surround the first sub-pixel 201, that is, the first sub-pixel 201 is located inside the first sub-virtual trapezoid M11, and the second sub-virtual trapezoid M12 may surround the second sub-pixel 202, that is, the second sub-pixel 202 is located inside the second sub-virtual trapezoid M12.

[0092] In the two base sides of the first virtual trapezoid M1, the distance between the third sub-pixels 203 at the two vertices corresponding to the shorter side is less than the distance between the third sub-pixels 203 at the two vertices corresponding to the longer side.

[0093] For example, continue to refer to Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, multiple first sub-pixels 201 and second sub-pixels 202 constitute a second virtual trapezoid M2. The center of the second sub-pixel 202 is located at the first vertex N1 of the second virtual trapezoid M2, and the center of the first sub-pixel 201 is located at the second vertex N2 of the second virtual trapezoid M2. The first vertex N1 and the second vertex N2 are alternately spaced, and the third sub-pixel 203 is located inside the second virtual trapezoid M2.

[0094] For example, in the two base sides of the second virtual trapezoid M2, the distance between the first sub-pixel 201 and the second sub-pixel 202 at the two vertices corresponding to the shorter side is less than the distance between the first sub-pixel 201 and the second sub-pixel 202 at the two vertices corresponding to the longer side. The third sub-pixel 203 is surrounded by the second virtual trapezoid M2 formed by the first sub-pixel 201 and the second sub-pixel 202.

[0095] Optional, such as Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the display panel 100 also includes a support portion 60. Optionally, the support portion 60 can be used to support the mask used in the manufacturing process of the display panel 100, so as to avoid the mask directly contacting the multiple film layers in the sub-pixel 20, thereby avoiding the situation where the mask scratches the surface of important areas such as the light-emitting area.

[0096] In this embodiment of the invention, the support portion 60 can be coupled with... Figure 2 The structure of the protrusion 401 used to form the partition portion 40 is similar. Combined Figure 10 As shown, Figure 10This is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention, wherein, along a direction h2 perpendicular to the plane where the substrate 1 is located, the support portion 60 protrudes from the surface of the pixel definition layer 50 toward a side away from the substrate 10. Exemplarily, the partition portion 40 is configured to include, as shown below... Figure 2 and Figure 3 When the protrusion 401 is shown, the height of the support 60 can be greater than or equal to the height of the protrusion 401.

[0097] For example, such as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, at least a portion of the support portion 60 is located on the edge of the first virtual trapezoid M1. The distance between two adjacent sub-pixels 20 located on the edge of the first virtual trapezoid M1 is larger than the spacing between sub-pixels located at other positions. By setting at least a portion of the support portion 60 to correspond to the edge of the first virtual trapezoid M1, this embodiment of the invention can reduce the difficulty of manufacturing the support portion 60 and reduce the possibility of the support portion 60 sliding into the pixel openings located around it.

[0098] Optional, such as Figure 9 As shown, the second partition portion 40B2 includes at least two second notches 40A2, and the at least two second notches 40A2 include a first sub-notch 40A21 and a second sub-notch 40A22, wherein the distance between the two endpoints of the first sub-notch 40A21 is greater than the distance between the two endpoints of the second sub-notch 40A22.

[0099] In this embodiment of the invention, at least a portion of the support portion 60 is located on the side of the first sub-notch 40A21 away from the second sub-notch 40A22. Based on this arrangement, on the one hand, the distance between the non-notch position of the second partition portion 40B2 and the support portion 60 can be increased, making full use of the space on the display panel 100 and increasing the pixel density, while reducing the difficulty of setting up the support portion 60. Moreover, the support portion 60 also has a certain isolation effect on lateral leakage current. Therefore, the setting of the notch 40A facing the support portion 60 will not cause crosstalk between sub-pixels 2 of different colors located on both sides of the notch 40.

[0100] Optional, such as Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the support portion 60 includes a first support portion 601. Along a third direction X3, the first support portion 601 is located between two adjacent third sub-pixels 203. Along a fourth direction X4, the first support portion 601 is located between the first sub-pixel 201 and the second sub-pixel 202. The third direction X3 and the fourth direction X4 intersect, and the third direction X3 intersects with the first direction X1 and the second direction X2 respectively; the fourth direction X4 intersects with the first direction X1 and the second direction X2 respectively.

[0101] For example, such as Figure 9 As shown, the first sub-pixel 201 includes two first notches 40A1, which are arranged along a third direction X3. The second sub-pixel 202 includes two second notches 40A2, one of which is located on the side of the second sub-pixel 202 closer to the first support portion 601, and the other is located on the side of the second sub-pixel 202 away from the first support portion 601. That is, of the two second notches 40A2 included in the second partition portion 40B2, only one of the second notches 40A2 is oriented towards the first support portion 601.

[0102] like Figure 9 As shown, the third sub-pixel 203 includes two third notches 40A3, which are arranged along the fourth direction X4.

[0103] Optional, such as 1 and Figure 11 As shown, Figure 11 This is a partially enlarged schematic diagram of another display panel provided in an embodiment of the present invention. The support portion 60 further includes a second support portion 602. Along a third direction X3, the second support portion 602 is located between the first sub-pixel 201 and the second sub-pixel 202. Along a fourth direction X4, the second support portion 602 is located between two adjacent third sub-pixels 203.

[0104] like Figure 11As shown, the first sub-pixel 201 includes two first notches 40A1 along a third direction X3. One first notch 40A1 is located on the side of the first sub-pixel 201 closer to the second support portion 602, and the other first notch 40A1 is located on the side of the first sub-pixel 201 away from the second support portion 602. The second sub-pixel 202 includes two second notches 40A2, which are arranged along a fourth direction X4. The third sub-pixel 203 includes two third notches 40A3 along a fourth direction X4. One third notch 40A3 is located on the side of the third sub-pixel 203 closer to the second support portion 602, and the other third notch 40A3 is located on the side of the third sub-pixel 203 away from the second support portion 602. That is, the orientation of one notch 40A in each of the two notches corresponding to the third sub-pixel 203 and the first sub-pixel 201 is towards the second support portion 602, which can increase the distance between the second support portion 602 and the non-notch position of the partition portion and reduce the manufacturing difficulty of the second support portion 602.

[0105] The first support part 601 and the second support part 602 can be set at positions in the display panel with different notch distribution patterns, which can improve the consistency of the support effect at positions in the display panel with different notch distribution patterns.

[0106] For example, such as Figure 1 As shown, the display panel includes at least one first group G1, and multiple first groups G1 are arranged in an array along a third direction X3 and a fourth direction X4. The third direction X3 and the fourth direction X4 intersect, and the third direction X3 intersects with the first direction X1 and the second direction X2 respectively; the fourth direction X4 intersects with the first direction X1 and the second direction X2 respectively.

[0107] like Figure 12 As shown, Figure 12 This is an enlarged schematic diagram of a first group provided in an embodiment of the present invention. The first group G1 includes multiple first subgroups G10 and multiple support portions 60 as described above. (In conjunction with...) Figure 13 As shown, Figure 13 This is an enlarged schematic diagram of a first subgroup provided in an embodiment of the present invention. The first subgroup G10 includes the aforementioned first virtual trapezoid M1.

[0108] like Figure 13 As shown, the first subgroup G10 also includes m1×n1 second virtual trapezoids M2 arranged along the third direction X3 and the fourth direction X4. Figure 13 The example uses m1=2 and n1=2.

[0109] like Figure 14 As shown, Figure 14The following is a simplified schematic diagram of the outline of a second virtual trapezoid provided in an embodiment of the present invention. The second virtual trapezoid includes a first side S31 and a second side S32 that are arranged opposite each other along a third direction X3, and a third side S33 and a fourth side S34 that are arranged opposite each other along a fourth direction X4.

[0110] In this embodiment of the invention, along the third direction X3, in two adjacent second virtual trapezoids M2 in the first subgroup G10, the first side S31 of one second virtual trapezoid M2 is reused as the second side S32 of the other second virtual trapezoid M2; along the fourth direction X4, in two adjacent second virtual trapezoids M2 in the first subgroup G10, the third side S33 of one second virtual trapezoid M2 is reused as the fourth side S34 of the other second virtual trapezoid M2. Based on this arrangement, multiple first subgroups G10 can be arrayed to form the aforementioned first group G1 while sharing sides, which can improve the regularity of the pattern within the first group G1, including sub-pixels and partitions, and is beneficial to improving process efficiency.

[0111] For example, such as Figure 12 As shown, the first group G1 includes m2×n2 first subgroups G10 arranged along the third direction X3 and the fourth direction X4. Figure 12 The example uses m²=3 and n²=3.

[0112] like Figure 13 and Figure 15 As shown, Figure 15 This is a simplified schematic diagram of the outline of a first subgroup provided in an embodiment of the present invention. The first subgroup G10 includes a first virtual polygon M21, as shown below. Figure 15 As shown, the first virtual polygon M21 includes a fifth side S41 and a sixth side S42 that are positioned opposite each other along the third direction X3, and a seventh side S43 and an eighth side S44 that are positioned opposite each other along the fourth direction X4.

[0113] In this embodiment of the invention, along the third direction X3, in two adjacent first subgroups G10 within the first group G1, the fifth edge S41 of one first subgroup G10 is reused as the eighth edge S44 of the other first subgroup G10; along the fourth direction X4, in two adjacent first subgroups G10 within the first group G1, the seventh edge S43 of one first subgroup G10 is reused as the eighth edge S44 of the other first subgroup G10. For example, as... Figure 15 As shown, the seventh side S43 and the eighth side S44 can be broken lines.

[0114] Based on the configuration provided in the embodiments of the present invention, the first group G1 can be used as a repeating unit including sub-pixels 20, partitions 40 and support parts 60. That is, multiple first groups G1 can be repeatedly arranged to fill the display area of ​​the display panel while sharing a side, which is beneficial to improve the distribution regularity of the pattern including sub-pixels 20, partitions 40 and support parts 60 in the display panel and facilitates the manufacturing process.

[0115] For example, in combination Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, in this embodiment of the invention, the orientation of the notches 40A of two adjacent first partition portions 40B1 on the third direction X3 is the same, and the orientation of the notches 40A of two adjacent first partition portions 40B1 on the fourth direction X4 is the same. This arrangement helps to reduce the size of the first group G1 as a repeating unit, simplifies the design, facilitates process monitoring during the manufacturing process, and helps to improve process yield and efficiency.

[0116] In yet another alternative implementation, such as Figure 16 As shown, Figure 16 This is a partially enlarged schematic diagram of another display panel provided in an embodiment of the present invention. In this embodiment of the present invention, at least part of the first partition portion 40B1 surrounding the first sub-pixel 201 does not include the notch 40A.

[0117] For example, the first sub-pixel 201 can be one of the sub-pixels in the display panel 100 with a lower activation voltage. That is, the first sub-pixel 201 is more sensitive to leakage current, and leakage current is more likely to cause brightness fluctuations in the first sub-pixel 201. By eliminating the notch on the first partition portion 40B1 corresponding to the first sub-pixel 201, the leakage current path between the first sub-pixel 201 and the adjacent sub-pixel 20 can be extended, reducing the leakage current impact of the adjacent sub-pixel 20 on the first sub-pixel 201, which is beneficial to improving the accuracy of the luminous brightness of the first sub-pixel 201.

[0118] Optionally, the first subpixel 201 is a red subpixel.

[0119] In yet another alternative implementation, refer to Figure 6 , Figure 7 , Figure 8 and Figure 9 and Figure 10As shown, in this embodiment of the invention, any one of the first sub-pixel 201, the second sub-pixel 202, and the third sub-pixel 203 can have only two gaps 40A in the corresponding partition portion 40, so as to balance the effects of suppressing the lateral leakage of the sub-pixel and improving the reliability of the second electrode 20C.

[0120] For example, such as Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 As shown, the shape of the orthographic projection of the partition portion 40 onto the plane of the substrate 10 includes an arc shape, so that the structure of the partition portion 40 follows the shape of the prepared sub-pixel 20, avoiding the situation where the light-emitting area of ​​the pixel 20 is covered when the structure of the partition portion 40 surrounding the sub-pixel 20 is inconsistent, and also helping to ensure that the structure of multiple film layers prepared after the partition portion 40 is more standardized.

[0121] Optional, such as Figure 17 As shown, Figure 17 This is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention. The sub-pixel 20 includes a first electrode 20A, a first light-emitting layer 20B1, a charge-generating layer 20E, a second light-emitting layer 20B2, and a second electrode 20C. The first electrode 20A is located on one side of the substrate 10. The first light-emitting layer 20B1 is located on the side of the first electrode 20A away from the substrate 10. The first light-emitting layer 20B1 is at least partially located within an opening 501 of the pixel definition layer 50, which may be a pixel opening. The charge-generating layer 20E is located on the side of the first light-emitting layer 20B1 away from the first electrode 20A. The second light-emitting layer 20B2 is located on the side of the charge-generating layer 20E away from the first light-emitting layer 20B1. The second electrode 20C is located on the side of the second light-emitting layer 20B2 away from the charge-generating layer 20E. The charge-generating layer 20E is located between the first light-emitting layer 20B1 and the second light-emitting layer 20B2.

[0122] For example, such as Figure 17 As shown, the charge generation layer 20E can be disconnected at the location of the partition portion 40. Alternatively, in some other embodiments, the charge generation layer 20E can also be provided to protrude away from the substrate 10 at the partition portion 40 to increase the transmission path of lateral leakage current in the charge generation layer 20E.

[0123] Optional, such as Figure 17As shown, taking the first electrode 20A as the anode and the second electrode 20C as the cathode as an example, the common layer 20D also includes a third sub-common layer 20D3 and a fourth sub-common layer 20D4. The third sub-common layer 20D3 can serve as an electron transport layer for transmitting electrons to the first light-emitting layer 20B1. The fourth sub-common layer 20D4 can serve as a hole transport layer for transmitting holes to the second light-emitting layer 20B2.

[0124] The display panel 100 provided in this embodiment of the invention improves the brightness of the sub-pixels 20 and reduces the power consumption of the display panel 100 by designing the sub-pixels 20 as a series structure including a first light-emitting layer 20B1 and a second light-emitting layer 20B2 stacked together, thereby increasing the lifespan of the display panel 100. Furthermore, by providing the aforementioned partition portion 40 in the display panel 100, this embodiment of the invention can suppress or isolate the lateral leakage current between two adjacent sub-pixels 20, overcoming the crosstalk problem between adjacent sub-pixels 20 caused by the high conductivity of the charge-generating layer 20E, thus improving the display quality of the display panel 100.

[0125] Based on the same inventive concept, embodiments of the present invention also provide a display device, such as... Figure 18 As shown, Figure 18 This is a schematic diagram of a display device provided in an embodiment of the present invention. The display device 200 includes the aforementioned display panel 100. The specific structure of the display panel 100 has been described in detail in the above embodiments and will not be repeated here. Figure 18 The display device shown is for illustrative purposes only. The display device can be any electronic device with display function, such as a mobile phone, tablet computer, laptop computer, e-reader or television.

[0126] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
