[0002] This application is a divisional application of application number 202422068259.1, filed on August 23, 2024, entitled "Display Panel and Display Device". Technical Field
[0003] This utility model relates to the field of display technology, specifically to a display panel and display device. Background Technology
[0004] 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.
[0005] 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, since these functional layers usually cover the entire surface of the display panel, 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 leads to crosstalk between different sub-pixels during display, for example, causing sub-pixels that should not emit light to do so, a phenomenon known as "light leakage," which affects the display effect. Utility Model Content
[0006] In view of this, the present invention provides a display panel and a display device to solve the problem of light-emitting devices stealing light due to lateral leakage in the related art.
[0007] In a first aspect, embodiments of the present invention provide a display panel, comprising:
[0008] Substrate;
[0009] Multiple sub-pixels arranged in an array along a first direction and a second direction on the same side of the substrate. Each sub-pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The i-th row of sub-pixels includes first sub-pixels and third sub-pixels arranged alternately along the first direction; the (i+1)-th row of sub-pixels includes third sub-pixels and second sub-pixels arranged alternately along the first direction; the j-th column of sub-pixels includes first sub-pixels and third sub-pixels arranged alternately along the second direction; the (j+1)-th column of sub-pixels includes third sub-pixels and second sub-pixels arranged alternately along the second direction; the second direction intersects the first direction.
[0010] The partition includes at least a first partition and a second partition, the first partition at least partially surrounding a first sub-pixel and including a first notch; the second partition at least partially surrounding a second sub-pixel and including a second notch.
[0011] The support portion is located between a first sub-pixel and an adjacent second sub-pixel along a third direction, and between two adjacent third sub-pixels along a fourth direction; the third direction intersects with the first direction and the second direction respectively; the fourth direction intersects with the first direction and the second direction respectively; the third direction intersects with the fourth direction.
[0012] The adjacent first sub-pixel and second sub-pixel include at least one of the non-notch portion of the first partition, the non-notch portion of the second partition, and the support portion; and at least one of the first sub-pixel and the second sub-pixel includes a protrusion and a main body portion, the edge of the protrusion portion away from the main body portion includes an arc segment, the arc segment protruding towards the side away from the main body portion.
[0013] Secondly, this utility model provides a display device including the aforementioned display panel.
[0014] The display panel and display device provided in this embodiment of the present invention, by setting a first partition portion partially surrounding the first sub-pixel and a second partition portion partially surrounding the second sub-pixel, can block or extend the path of lateral leakage current transmitted through the common layer between the first sub-pixel and its adjacent sub-pixels. Furthermore, by blocking or extending the path of lateral leakage current transmitted through the common layer between the second sub-pixel and its adjacent sub-pixels, the transmission of lateral leakage current can be suppressed, which is beneficial to improving the display effect, especially the display effect at low grayscale.
[0015] Furthermore, by providing a first notch in the first partition portion and a second notch in the second partition portion, this embodiment of the present invention can avoid the second electrode formed after the first partition portion and the second partition portion from being disconnected or thinned at the notch. This allows the second electrode to be formed into a continuous structure with a large thickness at the notch, which is beneficial to reduce the voltage drop of the signal transmitted by the second electrode during transmission and improve the voltage uniformity of the second electrode in the display area.
[0016] In addition, by providing a support portion in the display panel, this embodiment of the utility model can, on the one hand, support the mask used in the manufacturing process, and on the other hand, extend the path of lateral leakage current through the common layer between two adjacent sub-pixels, thereby suppressing the transmission of lateral leakage current and improving the reliability of the display panel.
[0017] Furthermore, in setting the aforementioned first notch, second notch, and support portion, this embodiment of the invention ensures that adjacent first and second sub-pixels include at least one of the non-notch portion of the first partition portion, the non-notch portion of the second partition portion, and the support portion. By comprehensively considering the positions of the first notch, second notch, and support portion, it avoids simultaneously setting the first and second notches between the first and second sub-pixels that are not adjacent to the support portion. It ensures that at least one suppression structure for extending or blocking the conduction path of lateral leakage current is included between the first and second sub-pixels that are not adjacent to the support portion, thereby suppressing the transmission of lateral leakage current between the first and second sub-pixels, reducing the possibility of crosstalk between the first and second sub-pixels, and reducing the possibility of the first and second sub-pixels stealing light, thus optimizing the low grayscale display effect of the display panel and improving the display quality of the display panel.
[0018] Secondly, in this embodiment of the invention, at least one of the first sub-pixel and the second sub-pixel includes a protrusion and a main body. The edge of the protrusion away from the main body includes an arc segment, which protrudes towards the side away from the main body. The protrusion and the main body can be located within the virtual circumscribed quadrilateral of the first sub-pixel or the second sub-pixel. On the one hand, compared with setting the shape of the first sub-pixel and the second sub-pixel according to their respective virtual circumscribed quadrilaterals, the setting method provided by this embodiment of the invention can reduce the area of the first sub-pixel or the second sub-pixel, thereby increasing the distance between the first sub-pixel or the second sub-pixel and the other sub-pixel adjacent to it. This is beneficial to reduce the process difficulty of setting the partition and support between the first sub-pixel and the other sub-pixel adjacent to it, and also reduces the process difficulty of setting the partition and support between the second sub-pixel and the other sub-pixel adjacent to it.
[0019] On the other hand, while ensuring that the minimum spacing between two adjacent sub-pixels remains unchanged, compared to setting the shape of the first or second sub-pixel to a square, this embodiment of the invention sets the first or second sub-pixel to include a protrusion, which is equivalent to cutting the arc edge of the circumscribed virtual quadrilateral corresponding to the first or second sub-pixel. This allows at least one vertex of the first or second sub-pixel to be recessed towards the center of the circumscribed virtual quadrilateral of the second sub-pixel, thereby leaving space for another sub-pixel adjacent to that sub-pixel to expand outward, thus increasing the area of the expanded sub-pixel and improving its aperture ratio. Moreover, compared with related technologies, the pixel design method provided by this embodiment of the invention can increase the total aperture ratio of a pixel unit including one first sub-pixel, one second sub-pixel, and two third sub-pixels without increasing the difficulty of the process, such as keeping the relevant process parameters (such as the minimum aperture spacing between adjacent sub-pixels, FMM rib, etc.) consistent with the prior art or still having design redundancy. This is beneficial to improving the display effect and display quality of the display panel. Attached Figure Description

[0058] To better understand the technical solution of this utility model, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0059] It should be understood that the described embodiments are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0060] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The singular forms “a,” “the,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0061] 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.
[0062] This utility model embodiment provides a display panel, such as Figure 1 As shown, Figure 1 This is a schematic diagram of a display panel according to an embodiment of the present invention. The display panel 100 includes: a substrate 1; and a plurality of sub-pixels 2 arranged in an array along a first direction h11 and a second direction h12 on the same side of the substrate 1. The sub-pixels 2 include a first sub-pixel 21, a second sub-pixel 22, and a third sub-pixel 23, and the emitted light colors of the first sub-pixel 21, the second sub-pixel 22, and the third sub-pixel 23 are different from each other. For example, the first sub-pixel 21 includes a red sub-pixel, the second sub-pixel 22 includes a blue sub-pixel, and the third sub-pixel 23 includes a green sub-pixel.
[0063] like Figure 1As shown, the i-th row sub-pixel 11_i includes a first sub-pixel 21 and a third sub-pixel 23 alternating along the first direction h11; the (i+1)-th row sub-pixel 11_i+1 includes a third sub-pixel 23 and a second sub-pixel 22 alternating along the first direction h11; the j-th column sub-pixel 12_j includes a first sub-pixel 21 and a third sub-pixel 23 alternating along the second direction h12; the (j+1)-th column sub-pixel 12_j+1 includes a third sub-pixel 23 and a second sub-pixel 22 alternating along the second direction h12; the second direction h12 intersects the first direction h11; where i and j are both arbitrary positive integers. The intersection of the second direction h12 and the first direction h11 defines the plane containing the substrate 1. Figure 1 The second direction h12 is perpendicular to the first direction h11 as an illustration.
[0064] For example, such as Figure 1 As shown, the display panel 100 also includes a partition portion 3, which includes a first partition portion 31 and a second partition portion 32. The first partition portion 31 at least partially surrounds the first sub-pixel 21, and the second partition portion 32 at least partially surrounds the second sub-pixel 22.
[0065] For example, such as Figure 2 As shown, Figure 2 This is a cross-sectional schematic diagram of a display panel provided in an embodiment of the present invention. The sub-pixel 2 includes a first electrode 201, a light-emitting layer 203, a second electrode 202, and a common layer 204. The partition portion 3 is located on the side of the common layer 204 closest to the substrate 1. Optionally, the common layer 204 includes a first sub-common layer 2041 and a second sub-common layer 2042. The first sub-common layer 2041 is located between the first electrode 201 and the light-emitting layer 203, and the second sub-common layer 2042 is located between the second electrode 202 and the light-emitting layer 203. Optionally, the common layer 204 can be fabricated using a common mask. The light-emitting layer 203 can be fabricated using a fine metal mask (FMM).
[0066] Optional, such as Figure 2 As shown, the display panel 100 also includes a pixel definition layer 8, which includes an opening 80 that exposes at least a portion of the first electrode 201.
[0067] In this embodiment of the invention, the first electrodes 201 of different sub-pixels 2 are independent of each other, and the second electrodes 202 of multiple sub-pixels 2 are electrically connected to each other.
[0068] Optionally, the first electrode 201 includes an anode, and the second electrode 202 includes a cathode. The first sub-common layer 2041 includes a hole injection layer and / or a hole transport layer. The second sub-common layer 2042 includes an electron injection layer and / or an electron transport layer.
[0069] like Figure 2 As shown, the partition portion 3 includes a protrusion 301 that protrudes toward the side away from the substrate 1. Optionally, the protrusion 301 includes a first side surface S11 and a first bottom surface S12 that is closer to the substrate 1. In this embodiment of the invention, the included angle between the first side surface S11 and the first bottom surface S12 toward the interior of the protrusion 301 can be an obtuse angle, that is, the area of the side of the protrusion 301 away from the substrate 1 is larger than the area of the side closer to the substrate 1. Based on this arrangement, the common layer 204 formed after the protrusion 301 cannot be formed (or continuously formed) on the first side surface S11, thus breaking at the protrusion 301. This can block the path of lateral leakage current through the common layer 204 between two adjacent sub-pixels 2, thereby suppressing the transmission of lateral leakage current and improving the display effect.
[0070] In another alternative implementation, such as Figure 3 As shown, Figure 3 This is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention. In this embodiment, the included angle between the first side surface S11 and the first bottom surface S12 towards the interior of the protrusion 301 can be an acute angle, that is, the area of the side of the protrusion 301 away from the substrate 1 is smaller than the area of the side closer to the substrate 1. Based on this arrangement, a common layer 204 formed after the protrusion 301 is formed on the first side surface S11. Based on the morphological characteristics of the protrusion 301, the path of lateral leakage current transmission through the common layer 204 between two adjacent sub-pixels 2 can be extended, thereby suppressing the transmission of lateral leakage current and improving the display effect.
[0071] In yet another alternative implementation, such as Figure 4 As shown, Figure 4 This is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention. The partition portion 3 includes a recessed portion 302 recessed on one side facing the substrate 1. The recessed portion 302 includes a second side surface S21 and a second bottom surface S22 on the side near the substrate 1, as shown below. Figure 4 As shown, the angle between the second side surface S21 and the second bottom surface S22 is an obtuse angle. Based on this arrangement, the common layer 204, which is formed after the recessed portion 302, is formed on the second side surface S21 of the recessed portion 302. Based on the morphological characteristics of the recessed portion 302, the path of lateral leakage current through the common layer 204 between two adjacent sub-pixels 2 can be extended, thereby suppressing the transmission of lateral leakage current and improving the display effect.
[0072] In yet another alternative implementation, such as Figure 5 As shown, Figure 5This is a cross-sectional schematic diagram of another display panel provided by an embodiment of the present invention. In this embodiment, the angle between the second side surface S21 and the second bottom surface S22 can also be an acute angle. Based on this arrangement, the common layer 204 formed after the recess 302 cannot be formed on the second side surface S21, thus breaking at the recess 302. This can block the path of lateral leakage current transmission between two adjacent sub-pixels 2 through the common layer 204, thereby suppressing the transmission of lateral leakage current and improving the display effect.
[0073] For example, such as Figure 4 and Figure 5 As shown, in this embodiment of the utility model, the recessed portion 302 can be formed in the pixel definition layer 8.
[0074] For example, when fabricating the display panel, the pixel definition layer 8 can be fabricated after the first electrode 201 is fabricated, and then the support portion 5 and the opening 80 can be fabricated using a half-grayscale mask. After the support portion 5 and the opening 80 are fabricated, a hard mask layer can be fabricated on the side of the support portion 5 away from the substrate 1. The hard mask layer includes multiple regions with different transmittance. Specifically, the transmittance of the region corresponding to the partition portion 3 in the hard mask layer is different from the transmittance of other positions. Under the blocking effect of the hard mask layer, the pixel definition layer 8 is etched, for example, by dry etching. This method is beneficial to increase the depth of the recess 302 formed on the pixel definition layer 20. When the common layer is subsequently formed, the amount of common layer that can be accommodated in the recess 302 will be larger, which is beneficial to extend the layout path of the common layer and the transmission path of electrical signals. Therefore, it is beneficial to block the leakage current transmission path and effectively avoid the problem of sub-pixel stealing light.
[0075] Optionally, the hard mask layer can be removed after the recess 302 is obtained. Methods for removing the hard mask layer include wet etching.
[0076] For example, the hard mask layer can be an IZO layer.
[0077] In another alternative embodiment, after the pixel definition layer 8 is fabricated, this embodiment of the invention can also use photoresist to cover the surface of the pixel definition layer 8, and then use patterning processes such as exposure, development, and etching to fabricate the recessed portion 302 in the pixel definition layer 8. Based on this method, the sidewalls and apical edges of the recessed portion 302 can be made smoother, reducing defects.
[0078] For example, such as Figure 4 and Figure 5As shown, in this embodiment of the invention, the depth of the recessed portion 302 can be less than the thickness of the pixel definition layer 8, that is, the second bottom surface S22 of the recessed portion 302 is located inside the pixel definition layer 8. Alternatively, in this embodiment of the invention, the depth of the recessed portion 302 can be equal to the thickness of the pixel definition layer 8, that is, the recessed portion 302 penetrates the pixel definition layer 8. In another optional embodiment, in this embodiment of the invention, the depth of the recessed portion 302 can be greater than the thickness of the pixel definition layer 8, that is, the recessed portion 302 penetrates the pixel definition layer 8 and continues to recess towards the side closer to the substrate 1, so that the second bottom surface S22 of the recessed portion 302 is located in other organic layers between the pixel definition layer 8 and the substrate 1. For example, a planarization layer may also be included between the pixel definition layer 8 and the substrate 1, and in this embodiment of the invention, the second bottom surface S22 of the recessed portion 302 is located inside the planarization layer.
[0079] For example, in this embodiment of the present invention, the first partition portion 31 and the second partition portion 32 may have the same shape. For example, both may be protrusions or both may be recesses.
[0080] Alternatively, in this embodiment of the invention, the shapes of the first partition portion 31 and the second partition portion 32 may be different. For example, one of the first partition portion 31 and the second partition portion 32 may be a protrusion and the other may be a recess.
[0081] In the embodiments of this utility model, such as Figure 1 As shown, the first partition portion 31 includes a first notch 41; the second partition portion 32 includes a second notch 42. That is, the first partition portion 31 is a non-closed shape including the first notch 41, and the second partition portion 32 is a non-closed shape including the second notch 42.
[0082] When the partition 3 is configured to include Figure 2 and Figure 3 The protrusion 301 shown or Figure 4 and Figure 5 When the recessed portion 302 is shown, the first partition portion 31 includes a first notch 41, meaning that the first partition portion 31 has an approximately flat structure at the location of the first notch 41, excluding both protrusions and recesses. The second partition portion 32 includes a second notch 42, meaning that the second partition portion 32 has an approximately flat structure at the location of the second notch 42, excluding both protrusions and recesses.
[0083] The provision of the first notch 41 and the second notch 42 can prevent the second electrode 202, which is formed after the first partition 31 and the second partition 32, from being disconnected or thinned at the first notch 41 and the second notch 42. This allows the second electrode 202 to be formed into a continuous structure with a large thickness at the first notch 41 and the second notch 42, which helps to reduce the voltage drop of the signal transmitted by the second electrode 202 during transmission, improve the voltage uniformity of the second electrode 202 in the display area, and improve the display uniformity of the display panel.
[0084] For example, such as Figure 1 As shown, the display panel 100 also includes a plurality of support portions 5; along a third direction h13, at least a portion of the support portions 5 are located between a first sub-pixel 21 and an adjacent second sub-pixel 22, and along a fourth direction h14, at least a portion of the support portions 5 are located between two adjacent third sub-pixels 23; both the third direction h13 and the fourth direction h14 are parallel to the plane of the substrate 1, and the third direction h13 intersects with the first direction h11 and the second direction h12 respectively; the fourth direction h14 intersects with the first direction h11 and the second direction h12 respectively; the third direction h13 and the fourth direction h14 intersect. Figure 1 The perpendicularity of the third direction h13 and the fourth direction h14 is used as an illustration.
[0085] Optionally, the support portion 5 can be used to support the mask used in the manufacturing process of the display panel 100.
[0086] For example, such as Figure 6 As shown, Figure 6 This is a cross-sectional schematic diagram of a first sub-pixel, a second sub-pixel, and a support portion provided in an embodiment of the present invention. Along a third direction h13, the support portion 5 is located between the first sub-pixel 21 and the second sub-pixel 22. Along a direction h2 perpendicular to the plane of the substrate 1, the support portion 5 protrudes from the surface of the pixel definition layer 8 toward a side away from the substrate 1. For example, when the aforementioned partition portion 3 is configured to include... Figure 2 and Figure 3 When the protrusion 301 is shown, it is combined with Figure 6 and Figure 3 As shown, the height H5 of the support part 5 is greater than or equal to the height H301 of the protrusion 301.
[0087] In one alternative implementation, such as Figure 6As shown, the support portion 5 includes a third side surface S51 and a third bottom surface S52 on the side closest to the substrate 1. In this embodiment, the included angle between the third side surface S51 and the third bottom surface S52 towards the interior of the support portion 5 can be an acute angle, that is, the area of the side of the support portion 5 away from the substrate 1 is smaller than the area of the side closest to the substrate 1. A common layer 204 formed after the support portion 5 can be formed on the third side surface S51.
[0088] In this embodiment of the invention, the area between adjacent first sub-pixels 21 and second sub-pixels 22 includes at least one of the following: a non-notch portion of the first partition portion 31, a non-notch portion of the second partition portion 32, and a support portion 5. The area defined as "between adjacent first sub-pixels 21 and second sub-pixels 22" refers to the area containing the quadrilateral defined by the two vertices of the first sub-pixel 21 and the two vertices of the second sub-pixel 22 adjacent to the first sub-pixel 21. The two vertices of the first sub-pixel 21 are the two vertices farthest apart from the plurality of vertices of the first sub-pixel 21 in a direction other than the direction intersecting the arrangement direction of the first sub-pixel 21 and the second sub-pixel 22. Similarly, the two vertices of the second sub-pixel 22 are the two vertices farthest apart from the plurality of vertices of the second sub-pixel 22 in a direction other than the direction intersecting the arrangement direction of the first sub-pixel 21 and the second sub-pixel 22.
[0089] For example, such as Figure 1 As shown, the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 on the third-direction h13 include a first gap 41, a second gap 42, and a support portion 5. Specifically, it includes only one of the three components: the non-gap portion of the first partition portion 31, the non-gap portion of the second partition portion 32, and the support portion 5. The inclusion of the first gap 41, the second gap 42, and the support portion 5 on the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 on the third-direction h13 means that the first gap 41, the second gap 42, and the support portion 5 are located within the first region AA1. The first region AA1 is quadrilateral, with its four vertices being two vertices of the first sub-pixel 21 and two vertices of the second sub-pixel 22. The two vertices of the first sub-pixel 21 are the two vertices farthest apart on the fourth direction h14 among the four vertices of the first sub-pixel 21, and the two vertices of the second sub-pixel 22 are the two vertices farthest apart on the fourth direction h14 among the four vertices of the second sub-pixel 22. Figure 1 The outline of the first region AA1 is shown with a dotted line.
[0090] The third direction h13 includes only the non-notch portion of the second partition portion 32, excluding the non-notch portion of the support portion 5 and the first partition portion 31.
[0091] In another alternative implementation, such as Figure 7 As shown, Figure 7 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. The first sub-pixel 21 and the second sub-pixel 22 on the third-direction h13 include a first notch 41, a second notch 42 and a support portion 5, that is, only the support portion 5 is included.
[0092] The third direction h13 includes only the non-notch portion of the first sub-pixel 21 and the second sub-pixel 22 between adjacent portions, excluding the non-notch portion of the support portion 5 and the second partition portion 32.
[0093] The adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 on the fourth direction h14 include a first gap 41, a second gap 42, and a support portion 5; that is, only the support portion 5 is included. Specifically, the inclusion of the first gap 41, the second gap 42, and the support portion 5 on the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 on the fourth direction h14 means that the first gap 41, the second gap 42, and the support portion 5 are located within a first region AA1. The first region AA1 is quadrilateral in shape, with its four vertices being the two vertices of the first sub-pixel 21 and the two vertices of the second sub-pixel 22, respectively, located within a third region AA1. The two vertices of the first sub-pixel 21 are the two vertices of the first sub-pixel 21 that are farthest apart on the third direction h13, and the two vertices of the second sub-pixel 22 are the two vertices of the second sub-pixel 22 that are farthest apart on the third direction h13. Figure 7 The outline of the first region AA1 is shown with a dotted line.
[0094] The second sub-pixel 22 of the first sub-pixel 21 and the second sub-pixel 22 of the adjacent part on the fourth direction h14 does not include the non-notch portion of the support portion 5 and the second partition portion 32, that is, it only includes the non-notch portion of the first partition portion 31.
[0095] In yet another alternative implementation, such as Figure 8 As shown, Figure 8 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. The first sub-pixel 21 and the second sub-pixel 22 on the third-direction h13 include a first notch 41, a second notch 42 and a support portion 5, that is, only the support portion 5 is included.
[0096] The third direction h13 includes only the non-notched portion of the first partition portion 31 and the non-notched portion of the second partition portion 32, excluding the support portion 5.
[0097] In yet another alternative implementation, such as Figure 9 As shown, Figure 9 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. The first sub-pixel 21 and the second sub-pixel 22 on the third-direction h13 include a first notch 41, a non-notch portion of the second partition portion 32 and a support portion 5. That is, it only includes the non-notch portion of the second partition portion 32 and the support portion 5.
[0098] The third direction h13 includes only the non-notch portion of the second partition portion 32 between the first sub-pixel 21 and the second sub-pixel 22, excluding the non-notch portion of the support portion 5 and the first partition portion 31.
[0099] In yet another alternative implementation, such as Figure 10 As shown, Figure 10 This is a schematic diagram of another display panel provided by an embodiment of the present utility model. On the third direction h13, the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 include a second notch 42, a non-notch portion of the first partition 31, and a support portion 5; that is, it only includes the non-notch portion of the first partition 31 and the support portion 5. On the third direction h13, another adjacent portion of the first sub-pixel 21 and the second sub-pixel 22 does not include the support portion 5 and the non-notch portion of the second partition 32; it only includes the non-notch portion of the first partition 31.
[0100] In yet another alternative implementation, such as Figure 11 As shown, Figure 11 This is a schematic diagram of another display panel provided by an embodiment of the present utility model. On the third direction h13, the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 include a non-notch portion of the first partition portion 31, a non-notch portion of the second partition portion 32, and a support portion 5. On the third direction h13, another adjacent portion of the first sub-pixel 21 and the second sub-pixel 22 does not include the support portion 5, but only the non-notch portions of the first partition portion 31 and the second partition portion 32.
[0101] As mentioned above, the provision of the first notch 41 and the second notch 42 can prevent the second electrode 202 from experiencing defects such as thinning or breakage at the locations of the first notch 41 and the second notch 42, which is beneficial to improving the connection reliability of the second electrode 202.
[0102] When setting the first notch 41, the second notch 42, and the support portion 5, this embodiment of the utility model ensures that at least one of the non-notch portion of the first partition portion 31, the non-notch portion of the second partition portion 32, and the support portion 5 is included between adjacent first sub-pixels 21 and 22. While ensuring the connection reliability of the second electrode 202, the positions of the first notch 41, the second notch 42, and the support portion 5 can be comprehensively considered. This avoids setting the first notch and the second notch simultaneously between the first sub-pixels and the second sub-pixels that are not adjacent to the support portion. It ensures that at least one suppression structure for extending or blocking the conduction path of lateral leakage current is included between the first sub-pixels 21 and 22 that are not adjacent to the support portion 5, so as to suppress the transmission of lateral leakage current between the first sub-pixels 21 and 22, reduce the possibility of crosstalk between the first sub-pixels 21 and 22, and reduce the possibility of the first sub-pixels 21 and 22 being overexposed. This optimizes the low grayscale display effect of the display panel and improves the display quality of the display panel. For example, when the first sub-pixel 21 is a red sub-pixel and the second sub-pixel 22 is a blue sub-pixel, based on the above-mentioned setting method provided by the present utility model embodiment, when displaying a blue screen, the possibility of red sub-pixels catching the light can be reduced, thereby improving the display quality of the blue screen.
[0103] In this embodiment of the utility model, combined with Figure 1 and Figure 12A As shown, Figure 12A An enlarged schematic diagram of a sub-pixel including a protrusion and a main body provided for an embodiment of the present utility model, wherein at least one of the first sub-pixel 21 and the second sub-pixel 22 includes a protrusion 201 and a main body 202, and the edge of the protrusion 201 away from the main body 202 includes an arc segment C, which protrudes toward the side away from the main body 202.
[0104] Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The second sub-pixel 22 is illustrated by including a protrusion 201 and a main body 202.
[0105] like Figure 12A As shown, the second sub-pixel 22 includes a virtual bounding quadrilateral 20, which includes a first virtual edge DE1, a second virtual edge DE2, a third virtual edge DE3, and a fourth virtual edge DE4. The third virtual edge DE3 connects to the same side of the first virtual edge DE1 and the second virtual edge DE2, and the fourth virtual edge DE4 is positioned opposite to the third virtual edge DE3. The first virtual edge DE1, the second virtual edge DE2, the third virtual edge DE3, and the fourth virtual edge DE4 are all straight line segments.
[0106] For example, such as Figure 12A As shown, the main body 202 includes a first side ZE1 and a second side ZE2; the protruding part 201 includes a third side ZE3, and the third side ZE3 includes the aforementioned arc segment C.
[0107] In this embodiment of the invention, the first virtual edge DE1 partially overlaps with the first edge ZE1, that is, at least one point of the first edge ZE1 is located on the first virtual edge DE1; as shown Figure 12A As shown, all points on the first edge ZE1 can be located on the first virtual edge DE1.
[0108] The second virtual edge DE2 partially overlaps with the second edge ZE2, that is, at least one point of the second edge ZE2 lies on the second virtual edge DE2; as Figure 12A As shown, all points on the second edge ZE2 can be located on the second virtual edge DE2.
[0109] At least one point of the third edge ZE3 coincides with the third virtual edge DE3, such as Figure 12A As shown, the third edge ZE3 and the third virtual edge DE3 are tangent at the first point P11.
[0110] Based on this configuration, at least one of the first sub-pixel 21 and the second sub-pixel 22 can have its orthographic projection onto the plane of the substrate 1 located within its corresponding virtual circumscribed quadrilateral 20.
[0111] It should be noted that the shape of each sub-pixel mentioned in the embodiments of this utility model refers to the shape of the opening 80 formed in the pixel definition layer 8. For example, as shown... Figure 2 As shown, when the opening 80 is set to have an area on the side away from the substrate 1 that is larger than the area on the side closer to the substrate 1, the shape of each sub-pixel refers to the shape of the area corresponding to the lower edge of the opening 80, that is, the shape of the area where the light-emitting layer in contact with the first electrode 201 is located, which is also the shape of the light-emitting area of the sub-pixel.
[0112] This embodiment of the invention, by configuring at least one of the first sub-pixel 21 and the second sub-pixel 22 to include a protrusion 201 and a main body 202, and configuring the edge of the protrusion 201 away from the main body 202 to include an arc segment C, can reduce the area of the corresponding sub-pixel compared to configuring the shape of both the first sub-pixel 21 and the second sub-pixel 22 as their respective circumscribed virtual quadrilaterals. For example, when the first sub-pixel 21 is configured to include a protrusion, the area of the first sub-pixel 21 can be reduced; when the second sub-pixel 22 is configured to include a protrusion, the area of the second sub-pixel 22 can be reduced; when both the first sub-pixel 21 and the second sub-pixel 22 are configured to include a protrusion 201, the areas of both the first sub-pixel 21 and the second sub-pixel 22 can be reduced simultaneously. The space between the protrusion 201 and the circumscribed virtual quadrilateral corresponding to the sub-pixel 2 is the area reduction portion. By reducing the area of sub-pixel 2, the distance between it and its adjacent sub-pixel 2 can be increased. This increases the transmission path of lateral leakage current between the two sub-pixels 2, reducing crosstalk. Furthermore, it provides space for the placement of the first partition 31, the second partition 32, and the support 5, reducing the manufacturing complexity of these components between the two sub-pixels. For example, the partition 3 and the support 5 can be kept at a certain distance from the first sub-pixel 21 and the second sub-pixel 22, respectively, to prevent them from falling into the pixel opening due to manufacturing errors or external forces, thus affecting the display.
[0113] On the other hand, while ensuring that the minimum spacing between two adjacent sub-pixels remains unchanged, compared to setting the shape of the first sub-pixel 21 or the second sub-pixel 22 to a square, this embodiment of the invention sets the first sub-pixel 21 or the second sub-pixel 22 to include a protrusion, which is equivalent to cutting the outer edge of the circumscribed virtual quadrilateral corresponding to the first sub-pixel 21 or the second sub-pixel 22. Taking cutting the outer edge of the circumscribed virtual quadrilateral corresponding to the second sub-pixel 22 as an example, after cutting the edge, it is equivalent to causing at least one vertex of the second sub-pixel 22 to shrink inward toward the center of the circumscribed virtual quadrilateral of the second sub-pixel 22, thereby leaving space for the other sub-pixel adjacent to the second sub-pixel 22 to expand outward, thereby increasing the area of the expanded sub-pixel and improving its aperture ratio.
[0114] For details, please refer to Figure 12B As shown, Figure 12BThis is a schematic diagram of a display panel in the related art, wherein the shape of the first sub-pixel 21 and the shape of the second sub-pixel 22 are both squares. The first sub-pixel 21 and the second sub-pixel 22 are arranged alternately along the third direction h13 and the fourth direction h14, respectively. The centers (i.e., centroids) of two adjacent first sub-pixels 21 and second sub-pixels 22 form a virtual square Qs. A third sub-pixel 23 is located within the virtual square Qs, and the center (i.e., centroid) of the third sub-pixel 23 coincides with the center of the virtual square Qs.
[0115] Taking the pixel pitch PL between the first sub-pixel 21 and the second sub-pixel 22 as 55 μm, the minimum aperture spacing t1 between the first sub-pixel 21 and the second sub-pixel 22 as 25 μm, the minimum aperture spacing t2 between the third sub-pixel 23 and the first sub-pixel 21 as 18 μm, the minimum aperture spacing t3 between the third sub-pixel 23 and the second sub-pixel 22 as 18 μm, the minimum aperture spacing t4 between two adjacent third sub-pixels 23 as 35 μm, and the distance Xr from the vertex to the center of the first sub-pixel 21 as 10.98 μm as an example, the area S1 of the first sub-pixel 21 can be calculated to be 241.12 μm. 2 The area S2 of the second sub-pixel 22 is 723.52 μm. 2 The area S3 of the third sub-pixel 23 is 308.15μm. 2 For a pixel unit containing a first sub-pixel 21, a second sub-pixel 22, and two third sub-pixels 23, the aperture area of the pixel unit is Stotal = S1 + S2 + 2S3 = 1580.94 μm. 2 .
[0116] refer to Figure 12C and Figure 12D As shown, Figure 12C An enlarged schematic diagram of another sub-pixel including a protrusion and a main body, provided for an embodiment of this utility model. Figure 12D A display panel and a display panel provided for embodiments of this utility model Figure 12B The diagram shows a comparison of display panels in related technologies. Figure 12D The shapes of the first sub-pixel 21 and the second sub-pixel 22 are both according to Figure 12C The shape of the sub-pixel is designed, wherein the sub-pixel includes a protrusion 201 and a main body 202. The arc segment C includes a first arc segment C1 and a second arc segment C2. The edge of the protrusion 201 away from the main body 202 also includes a straight line segment L connecting the first arc segment C1 and the second arc segment C2. The length of the first arc segment C1 is greater than the length of the second arc segment C2. The two endpoints of the first arc segment C1 are P1 and P2, the two endpoints of the second arc segment C2 are P3 and P4, and the two endpoints of the straight line segment L are P2 and P3.
[0117] exist Figure 12D In this embodiment, the minimum aperture spacing g1 between the first sub-pixel 21 and the second sub-pixel 22 is 25 μm, the minimum aperture spacing g2 between the third sub-pixel 23 and the first sub-pixel 21 is 18 μm, the minimum aperture spacing g3 between the third sub-pixel 23 and the second sub-pixel 22 is 18 μm, and the minimum aperture spacing g4 between two adjacent third sub-pixels 23 is 35 μm. That is to say, the minimum aperture spacing between any two of the first sub-pixel 21, the second sub-pixel 22, and the third sub-pixel 23, as well as the minimum spacing between two adjacent third sub-pixels 23, are set to be equal to the corresponding minimum aperture spacing in the related art.
[0118] It should be noted that in related technologies, since both the first sub-pixel 21 and the second sub-pixel 22 are square in shape, the minimum opening distance between them is the distance along the line connecting the centers of the sub-pixels (the side of the virtual square Qs). In this embodiment of the present invention, the first sub-pixel 21 and the second sub-pixel 22 are arranged according to... Figure 12A and Figure 12C The configuration is such that, after including the aforementioned protrusion 201, the minimum opening distance g1 between the first sub-pixel 21 and the second sub-pixel 22 is not equal to the distance between them on the side of the virtual square Qs. For example, combined with Figure 12C and Figure 12D As shown, the minimum opening distance g1 between the first sub-pixel 21 and its adjacent second sub-pixel 22 on the third direction h13 is the distance between point P4 of the first sub-pixel 21 and the right-angle vertex of the second sub-pixel 22; the minimum opening distance g1 between the first sub-pixel 21 and its adjacent second sub-pixel 22 on the fourth direction h14 is the distance between point P4 of the second sub-pixel 22 and the right-angle vertex of the first sub-pixel 21; the minimum opening distance between any other adjacent first sub-pixel 21 and second sub-pixel 22 is also the same, and will not be described again.
[0119] by Figure 12C Taking the first sub-pixel 21 with Xa = Xb = 2.8 μm and the length of the line segment L from P2 to P3 as 5 μm, and the second sub-pixel 22 with Xa = Xb = 2.7 μm and the length of the line segment L from P2 to P3 as 6 μm as 6 μm, the calculated value is: S1 = 261.56 μm. 2 S2 = 799.45 μm 2 S3 = 279.84 μm 2 The sum of the aperture areas of a single pixel unit is Stotal = S1 + S2 + 2S3 = 1620.69 μm. 2 .
[0120] It can be seen that the minimum spacing between any two adjacent sub-pixels is... Figure 12B While maintaining consistency with the related technologies shown, compared with the case where the shapes of the first sub-pixel 21 and the second sub-pixel 22 are both set to squares, the setting method provided by this utility model embodiment can increase the area of the first sub-pixel 21 and the second sub-pixel 22, improve their aperture ratio, and also improve the total aperture ratio of the pixel unit including one first sub-pixel 21, one second sub-pixel 22 and two third sub-pixels 23.
[0121] Furthermore, in this embodiment of the invention, the design of the third sub-pixel 23 is not only affected by g2 and g3 as described above, but also by the spacing of the mask openings of the fine metal mask (FMM). The spacing of the mask openings of the fine metal mask is also referred to as the rib width of the fine metal mask. To ensure the strength of the fine metal mask, the spacing between the mask openings is limited. Therefore, the distance between two adjacent third sub-pixels 23 in the third direction h13 and the fourth direction h14 is also limited. This limitation does not shrink due to the outward expansion of the first sub-pixel 21 and the second sub-pixel 22. That is to say, compared with related technologies, the two opposite sides of the third sub-pixel 23 along the third direction h13 and the two opposite sides along the fourth direction h14 in this embodiment of the invention do not shrink inward. Therefore, even if the minimum aperture spacing g2 between the third sub-pixel 23 and the first sub-pixel 21, and the minimum aperture spacing g3 between the third sub-pixel 23 and the second sub-pixel 22 can satisfy g2≥t2 and g3≥t3 respectively, when the first sub-pixel 21 and the second sub-pixel 22 expand outward, at least some sides of the third sub-pixel 23 located in the virtual square Qs will be shrunk inward, reducing the aperture area of the third sub-pixel 23. However, based on the setting method provided by the present utility model embodiment, it is possible to avoid the two sides of the third sub-pixel 23 opposite to each other along the third direction h13 and the two sides opposite to each other along the fourth direction h14, and to avoid setting the aperture area of the third sub-pixel 23 too small. It is possible to ensure that the total aperture ratio within a pixel unit including one first sub-pixel 21, one second sub-pixel 22 and two third sub-pixels 23 is still increased compared to related technologies.
[0122] In summary, compared with related technologies, the pixel design method provided by this utility model embodiment can increase the total aperture ratio of a pixel unit including a first sub-pixel 21, a second sub-pixel 22 and two third sub-pixels 23 without increasing the difficulty of the process, such as keeping the relevant process parameters (such as the minimum aperture spacing between adjacent sub-pixels, FMM rib, etc.) consistent with the prior art or still having design redundancy. This is beneficial to improving the display effect and display quality of the display panel.
[0123] For example, such as Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the first sub-pixel 21 includes a first sub-pixel 211, and the support portion 5 is located between the first sub-pixel 211 and the second sub-pixel 22.
[0124] like Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, along the third direction h13, at least a portion of the support portion 5 is located between the first sub-pixel 211 and the second sub-pixel 22. Figure 7 As shown, along the fourth direction h14, a portion of the support portion 5 is located between the first sub-pixel 211 and the second sub-pixel 22.
[0125] The first sub-pixel 211 includes a vertex A, which is formed by two adjacent sides of the first sub-pixel 211. Either of the two adjacent sides can be a straight line segment or an arc segment. Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The first 60-year pixel 211 is represented by four straight line segments.
[0126] In this embodiment of the present invention, the first partition portion 31 includes a first sub-partition portion 311, which at least partially surrounds the first sub-pixel 211.
[0127] Optional, such as Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the first sub-partition 311 includes a first notch 41 corresponding to the apex A of the first sub-pixel 211. The apex A of the first sub-pixel 211 and the first notch 41 correspond to each other when the line connecting the center of the first notch 41 and the centroid of the virtual circumscribed quadrilateral of the first sub-pixel 211 passes through the apex A. The center of the first notch 41 refers to the midpoint of the line connecting the two endpoints of the first partition 31 forming the first notch 41.
[0128] By setting the first notch 41 to correspond to the apex A of the first Jiazi pixel 211, the second electrode 202 can have a larger thickness around the apex A of the first Jiazi pixel 211, so that the second electrode 202 of the first Jiazi pixel 211 is well connected at the position where the apex A of the first Jiazi pixel 211 is located.
[0129] Furthermore, since the first sub-pixel 211 is located close to the support portion 5, by forming the first notch 41 corresponding to the top corner A, that is, by not setting the first sub-partition 311 at the location of the first notch 41, the space available for setting the support portion 5 can be increased while the distance between the first sub-pixel 211 and the adjacent second sub-pixel 22 is fixed, which helps to reduce the difficulty of setting the support portion 5.
[0130] It is understood that the centroid of the virtual circumscribed quadrilateral mentioned in this embodiment can be defined as the center point of mass distribution of the virtual circumscribed quadrilateral's geometry, i.e., the center of mass. If the virtual circumscribed quadrilateral has a regular geometric shape, then its geometric center and centroid coincide. For example, if the virtual circumscribed quadrilateral is a parallelogram, the intersection of its two diagonals is both its geometric center and its centroid. If the virtual circumscribed quadrilateral has an asymmetrical, irregular geometric shape, its centroid can be determined using 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 virtual circumscribed quadrilateral is also difficult to determine.
[0131] It should be noted that the regular shapes (regular geometric shapes) in this utility model 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.
[0132] For example, such as Figure 13 As shown, Figure 13 This is an enlarged schematic diagram of a first Jiazi pixel, a first partition, and a support provided in an embodiment of the present invention. The first Jiazi pixel 211 includes at least two vertex corners A. Figure 13 As illustrated, the shape of the first Jiazi pixel 211 is designed as a quadrilateral, wherein the intersection of two adjacent sides of the first Jiazi pixel 211 forms the aforementioned vertex A. Figure 13In the illustrated embodiment, the first sub-pixel 211 includes four vertices A. The first sub-partition 311 includes at least two first notches 41, each corresponding to a different vertices A; along a third direction h13, one first notch 41 is located on the side of the first sub-pixel 211 closer to the support portion 5, and the other first notch 41 is located on the side of the first sub-pixel 211 away from the support portion 5. That is, the two first notches 41 and the support portion 5 are arranged along a third direction h13. Figure 13 As shown, the line connecting the centroid of the virtual outer quadrilateral of the first Jiazi pixel 211 and the centroid of the support part 5 passes through the two first gaps 41 mentioned above.
[0133] The first notch 41 located near the support portion 5 avoids the presence of protrusions or recesses around the apex A of the first sub-pixel 211 near the support portion 5, thus preventing protrusions or recesses from encroaching on the space of the support portion 5 and reducing the difficulty of setting up the support portion 5. Furthermore, the placement of the first notch 41 further away from the support portion 5 increases the number of first notches 41, thereby increasing the number of reliable connection points for the second electrode and increasing the conduction path for the signal transmitted by the second electrode. For example, at least in the arrangement directions of these two first notches 41, the signal transmitted by the second electrode can be transmitted smoothly.
[0134] Optional, such as Figure 13 As shown, the distance between the two endpoints of the first notch 41 away from the support part 5 is S111, and the distance between the two endpoints of the first notch 41 near the support part 5 is S112, where S111≤S112. Based on this arrangement, by making the distance between the two endpoints of the first notch 41 near the support part 5 larger, the distance between the support part 5 and the non-notch portion of the first sub-partition 311 can be increased, thereby further reducing the difficulty of setting up the support part 5.
[0135] For example, such as Figure 13 As shown, the length of the support portion 5 in the fourth direction h14 is S5, where S111≤S5≤S112. In this way, while avoiding mutual interference between the first sub-partition 311 and the support portion 5, the distance between the support portion 5 and the first sub-pixel 211 can be reduced. For example, the area of the first sub-pixel 211 can be set as large as possible to increase its aperture ratio, avoid driving the display of the first sub-pixel 211 with excessive current density, extend its lifespan, and improve the display effect of the display panel 100.
[0136] For example, in combination Figure 7 and Figure 14 As shown, Figure 14This is an enlarged schematic diagram of another first sub-pixel, first partition, and support provided in an embodiment of the present invention. The first sub-pixel 211 further includes multiple first sub-edges E11, with two adjacent first sub-edges E11 forming the apex A of the first sub-pixel 211. The first partition 311 also includes a first notch 41 corresponding to the first sub-edges E11. The correspondence between the first notch 41 and the first sub-edge E11 refers to the fact that the line connecting the center of the first notch 41 and the centroid of the virtual circumscribed quadrilateral of the first sub-pixel 211 passes through the first sub-edge E11.
[0137] Based on the first notch 41 corresponding to the apex A, the number of first notches 41 in the first sub-partition 311 can be further increased by setting the first notch 41 corresponding to the first edge E11, thereby improving the reliability of the second electrode set at the first edge E11, increasing the reliable transmission path of the signal transmitted by the second electrode, reducing the signal voltage drop, and helping to improve display uniformity. Figure 14 As an illustration, two first notches 41 corresponding to the first edge E11 and one first notch 41 corresponding to the apex A are provided in the first sub-partition 311.
[0138] In the embodiments of this utility model, such as Figure 14 As shown, the distance between the two endpoints of the first notch 41 corresponding to the first edge E11 of the first A is S113, and the distance between the two endpoints of the first notch 41 corresponding to the apex A of the first A sub-pixel 211 and close to the support portion 5 is S112, where S113 ≤ S112. Based on this arrangement, by making the distance between the two endpoints of the first notch 41 close to the support portion 5 larger, the distance between the support portion 5 and the first sub-partition portion 311 can be increased, thereby further reducing the difficulty of setting the support portion 5. In addition, by making the distance between the two endpoints of the first notch 41 corresponding to the first edge E11 of the first A as small as possible, the area of the region where lateral leakage current occurs around the first A sub-pixel 211 can be reduced, thereby further improving the reliability of the display panel.
[0139] For example, such as Figure 14 As shown, the length of the support portion 5 in the fourth direction h14 is S5, where S113≤S5≤S112. Based on this arrangement, while avoiding mutual interference between the first sub-partition portion 311 and the support portion 5, the distance between the support portion 5 and the first sub-pixel 211 can be reduced. For example, the area of the first sub-pixel 211 can be set as large as possible to increase the aperture ratio of the first sub-pixel 211, avoid driving the display of the first sub-pixel 211 with excessive current density, extend the lifespan of the first sub-pixel 211, and improve the display effect of the display panel 100.
[0140] For example, such as Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the first sub-pixel 21 includes a first secondary sub-pixel 212, and the first secondary sub-pixel 212 and its adjacent second sub-pixel 22 do not include a support portion 5. For example, the first secondary sub-pixel 212 and its adjacent second sub-pixel 22 in the third direction h13 do not include a support portion 5; and the first secondary sub-pixel 212 and its adjacent second sub-pixel 22 in the fourth direction h14 also do not include a support portion 5.
[0141] For example, such as Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, the first sub-pixel 212 includes a apex corner A, and the first partition portion 31 includes a second sub-partition portion 312. The second sub-partition portion 312 at least partially surrounds the first sub-pixel 212, and the second sub-partition portion 312 includes a first notch 41 corresponding to the apex corner A of the first sub-pixel 212. This first notch 41 can ensure a good connection of the second electrode located outside the apex corner A of the first sub-pixel 212.
[0142] For example, in this embodiment of the present invention, the first sub-pixel 212 includes at least two apex corners A, and the second sub-partition 312 includes at least two first notches 41, the two first notches 41 corresponding to different apex corners A; along the third direction h13 or the fourth direction h14, the two first notches 41 are located on both sides of the first sub-pixel 212. Figure 1 and Figure 9 The two first gaps 41 are arranged along the third direction h13 on both sides of the first sub-pixel 212 as an illustration. Figure 10 The two first openings 41 are arranged along the fourth direction h14 on both sides of the first sub-pixel 212 as an illustration.
[0143] In another alternative implementation, such as Figure 8 As shown, the first sub-partition 311 includes only one first notch 41 corresponding to the apex A of the first sub-pixel 211 and located near the support portion 5. This arrangement reduces the number of first notches 41 around the first sub-pixel 211, further mitigating the problem of light leakage from the first sub-pixel 211. For example, in this embodiment, the second sub-partition 312 may also have only one first notch 41 corresponding to the apex A of the first sub-pixel 212.
[0144] Optionally, in this embodiment of the invention, the number and positional distribution of the first notch 41 around the first sub-pixel 211 and the first notch 41 around the first sub-pixel 212 can be made as consistent as possible, thereby making the degree of lateral leakage current around the first sub-pixel 211 and the first sub-pixel 212 more consistent, and the morphology of the second electrode of the first sub-pixel 211 and the second electrode of the first sub-pixel 212 more consistent, so as to improve the display consistency of the first sub-pixel 211 and the first sub-pixel 212 and improve the display uniformity of the display panel.
[0145] When setting the first notch 41 corresponding to the apex A of the first sub-pixel 212, the distance between the two endpoints of the first notch 41 corresponding to the apex A of the first sub-pixel 212 is S121, and the distance between the two endpoints of the first notch 41 corresponding to the apex A of the first sub-pixel 211 and close to the support portion 5 is S112. In this embodiment of the invention, S121 ≤ S112. Since the support portion 5 is not provided around the first sub-pixel 212, the area left for the first partition portion 31 is relatively large. The distance between the two endpoints of the first notch 41 corresponding to the apex A of the first sub-pixel 212 can be appropriately compressed. Without affecting the setting of the support portion 5, the area of the region where lateral leakage current occurs around the first sub-pixel 212 can be reduced, thereby further improving the display effect of the display panel.
[0146] For example, such as Figure 7 As shown, the first sub-pixel 212 also includes multiple first edges E12, and two adjacent first edges E12 form the apex A of the first sub-pixel 212. The second sub-partition 312 also includes a first notch 41 corresponding to the first edge E12.
[0147] Combination Figure 7 and Figure 15 As shown, Figure 15 This is an enlarged schematic diagram of a first sub-pixel and a first partition portion provided in an embodiment of the present invention. The distance between the two endpoints of the first notch 41 corresponding to the edge E12 of the first sub-pixel is S122. Figure 14 As shown, the distance between the two endpoints of the first notch 41 corresponding to the apex A of the first sub-pixel 211 and close to the support portion 5 is S112. In this embodiment of the invention, S122≤S112. The first sub-pixel 212 does not have a support portion 5 around it. Therefore, by minimizing the distance between the two endpoints of the first notch 41 corresponding to the edge E12 of the first sub-pixel 212, this embodiment of the invention can reduce the area of the region where lateral leakage current occurs around the first sub-pixel 212 without affecting the setting of the support portion 5, thereby further improving the display effect of the display panel.
[0148] For example, continue to refer to Figure 9 and Figure 10 As shown, the first sub-pixel 21 includes the first sub-pixel 211 and the first sub-pixel 212. Along the third direction h13 or the fourth direction h14, the support portion 5 is located between the first sub-pixel 211 and the second sub-pixel 22. The support portion 5 is not included between the first sub-pixel 212 and the second sub-pixel 22. Figure 9 and Figure 10 The diagram illustrates the support portion 5 positioned between the first sub-pixel 211 and the second sub-pixel 22 along the third direction h13.
[0149] like Figure 9 and Figure 10 As shown, the first partition portion 31 includes a first A partition portion 313 and a first B partition portion 314. The first A partition portion 313 at least partially surrounds the first A sub-pixel 211, and the first B partition portion 314 at least partially surrounds the first B sub-pixel 212. For example, the first A partition portion 313 includes the aforementioned first sub-partition portion 311, and the first B partition portion 314 includes the aforementioned second sub-partition portion 312.
[0150] In this embodiment of the invention, the shape of the first partition portion 313 is the same as the shape of the first partition portion 314; the shape of the first notch 41 in the first partition portion 313 is the same as the shape of the first notch 41 in the first partition portion 314. The length of the first partition portion 313 is the same as the length of the first partition portion 314; the width of the first partition portion 313 is the same as the width of the first partition portion 314; wherein, the length direction of the first partition portion 313 and the first partition portion 314 is parallel to their respective extension direction, and the width direction is perpendicular to their respective extension direction. The distance between the two endpoints of the first notch 41 in the first partition portion 313 is the same as the distance between the two endpoints of the first notch 41 in the first partition portion 314. Figure 9 and Figure 10 As shown, the first sub-pixel 211 can be superimposed on the first sub-pixel 212 by translation. The first partition portion 313 can be superimposed on the first partition portion 314 by translation. The first gap 41 in the first partition portion 313 can be superimposed on the first gap 41 in the first partition portion 314 by translation.
[0151] Based on this configuration, the distribution patterns of the first partition portion 31 and the first gap 41 around the first sub-pixel 211 and the first sub-pixel 212, which have different positional relationships with the support portion 5, can be made the lateral leakage current around the first sub-pixel 211 and the first sub-pixel 212 tend to be consistent, and the morphology of the second electrode of the first sub-pixel 211 and the second electrode of the first sub-pixel 212 tend to be consistent, which is beneficial to improving the display uniformity of the display panel.
[0152] Optional, such as Figure 9 As shown, the first notch 41 in the first partition 313 corresponds to the apex A of the first sub-pixel 211; the first notch 41 in the first partition 314 corresponds to the apex A of the first sub-pixel 212; along the third direction h13, the two first notches 41 are located on both sides of the first sub-pixel 211, and the two first notches 41 are located on both sides of the first sub-pixel 212.
[0153] Or, such as Figure 10 As shown, along the fourth direction h14, two first gaps 41 are located on both sides of the first sub-pixel 211, and two first gaps 41 are located on both sides of the first sub-pixel 212.
[0154] Optional, based on Figure 10 The arrangement shown allows for appropriate compression of the widths of the first partition 313 (A) and the first partition 314 (B), preventing the first partition 313 from interfering with the support 5. For example, the width W of the first partition 313 (A) and the first partition 314 (B) can satisfy 1.5μm ≤ W ≤ 3.5μm.
[0155] The above description describes the case where the first sub-pixel 21 is designed as a quadrilateral. In another embodiment, the first sub-pixel 21 may also be configured to include the aforementioned protrusion and main body. (Combined with...) Figure 16 and Figure 17 As shown, Figure 16 This is a schematic diagram of yet another display panel provided in an embodiment of the present utility model. Figure 17 for Figure 16 An enlarged schematic diagram of a first type of sub-pixel, a second type of sub-pixel, a third type of sub-pixel and a fourth type of sub-pixel, wherein the first sub-pixel 21 includes a protrusion 201 and a main body 202; the protrusion 201 includes a first edge E1 away from the main body 202, and the first edge E1 includes an arc segment C.
[0156] In this embodiment of the invention, the first sub-pixel 21 includes a virtual bounding quadrilateral. For example... Figure 17As shown, the first sub-pixel 21 includes a first type of sub-pixel 213, a second type of sub-pixel 214, a third type of sub-pixel 215, and a fourth type of sub-pixel 216. The centroid Q1 of the virtual circumscribed quadrilateral of the first type of sub-pixel 213 projected onto the plane of the substrate 1 points towards the center Q2 of the first edge E1, which is parallel to the first direction h11. The centroid Q1 of the virtual circumscribed quadrilateral of the second type of sub-pixel 214 projected onto the plane of the substrate 1 points towards the center Q2 of the first edge E1, which is parallel to the second direction h12. The centroid Q1 of the virtual circumscribed quadrilateral of the third type of sub-pixel 215 projected onto the plane of the substrate 1 points towards the center Q2 of the first edge E1, which is parallel to the opposite direction of the first direction h11. The centroid Q1 of the virtual circumscribed quadrilateral of the fourth type of sub-pixel 216 projected onto the plane of the substrate 1 points towards the center Q2 of the first edge E1, which is parallel to the opposite direction of the second direction h12. The center of the first edge E1 refers to the midpoint of the line connecting the two endpoints of the first edge E1.
[0157] When arranging the first type of sub-pixels 213, the second type of sub-pixels 214, the third type of sub-pixels 215, and the fourth type of sub-pixels 216, for example, as follows: Figure 16 As shown, in any row of sub-pixels, such as in the m-th row of sub-pixels 11_m, the present invention embodiment can arrange the first type of sub-pixels 213, the fourth type of sub-pixels 216, the second type of sub-pixels 214 and the third type of sub-pixels 215 alternately along the first direction h11.
[0158] For example, such as Figure 16 As shown, for sub-pixels in the m-th row 11_m and the (m+2)-th row 11_m+2, the fourth type sub-pixel 216 in one row can be aligned with the second type sub-pixel 214 in the other row along the second direction h12. Similarly, the first type sub-pixel 213 in one row can be aligned with the third type sub-pixel 215 in the other row along the second direction h12. That is, in any column of sub-pixels, such as in the n-th column 11_n, this embodiment allows the second type sub-pixel 214, the fourth type sub-pixel 216, the first type sub-pixel 213, and the third type sub-pixel 215 to be arranged alternately along the second direction h12. Both m and n are positive integers. Based on this arrangement, the first sub-pixels 21 of the protrusions 201 with different orientations can be evenly distributed in the display panel, which helps improve display uniformity.
[0159] For example, such as Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 16As shown, the second sub-pixel 22 includes a second sub-pixel 221, and the support portion 5 is located between the second sub-pixel 221 and the first sub-pixel 21; the second sub-pixel 221 includes a vertex A. The vertex A of the second sub-pixel 221 is formed by two adjacent sides of the second sub-pixel 22. In this embodiment of the present invention, either of the two adjacent sides of the second sub-pixel 22 can be a straight line segment or an arc segment. Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 16 The second sub-pixel 22 is illustrated by its edge comprising one arc segment and three straight line segments. The aforementioned second partition 32 includes a third sub-partition 321, which at least partially surrounds the second sub-pixel 221.
[0160] Optional, such as Figure 18 As shown, Figure 18 This is an enlarged schematic diagram of a second sub-pixel, a third sub-partition, and a support provided in an embodiment of the present invention. The third sub-partition 321 includes a second notch 42 corresponding to the apex corner A of the second sub-pixel 221.
[0161] Optional, such as Figure 1 , Figure 7 , Figure 8 and Figure 10 As shown, along the third direction h13, at least part of the support portion 5 is located between the second sub-pixel 221 and the aforementioned first sub-pixel 211.
[0162] Or, such as Figure 7 As shown, along the fourth direction h14, another part of the support portion 5 is located between the second sub-pixel 221 and the aforementioned first sub-pixel 211.
[0163] By setting the second notch 42 to correspond to the apex A of the second Jiazi pixel 221, the second electrode 202 can have a larger thickness at the apex A of the second Jiazi pixel 221, thus ensuring a reliable connection between the second electrode 202 and the apex A of the second Jiazi pixel 221.
[0164] For example, such as Figure 1 , Figure 7 , Figure 8 and Figure 10As shown, the second notch 42 corresponding to one of the apex A of the second Jiazi pixel 221 is located on the side of the second Jiazi pixel 221 near the support portion 5. Because the second Jiazi pixel 221 is located near the support portion 5, this embodiment of the invention, by placing the second notch 42 corresponding to the apex A of the second Jiazi pixel 221 on the side of the second Jiazi pixel 221 near the support portion 5, avoids the protrusions or recesses occupying the space of the support portion 5, thus reducing the difficulty of setting the support portion 5. Furthermore, based on this setting method, it is not necessary to excessively compress the area of the support portion 5, ensuring the supporting effect of the support portion 5.
[0165] For example, continue to refer to Figure 7 and Figure 10 As shown, the second sub-pixel 221 includes at least two apex corners A, and the third sub-partition 321 includes at least two second notches 42, each corresponding to a different apex corner A. One second notch 42 is located on the side of the second sub-pixel 221 closer to the support portion 5, and the other second notch 42 is located on the side of the second sub-pixel 221 farther from the support portion 5. The second notch 42 located closer to the support portion 5 avoids the presence of protrusions or recesses around the apex corner A on the side of the second sub-pixel 221 closer to the support portion 5, preventing protrusions or recesses from encroaching on the space of the support portion 5 and reducing the difficulty of setting the support portion 5. Furthermore, the arrangement of the second notch 42 farther from the support portion 5 increases the number of second notches 42, thereby increasing the number of reliable connection positions for the second electrode and increasing the conduction path for the signal transmitted by the second electrode. For example, at least in the arrangement direction of these two second notches 42, the signal transmitted by the second electrode can be transmitted smoothly.
[0166] In this embodiment of the utility model, reference continues to be made to... Figure 7 As shown, the distance between the two endpoints of the second notch 42 away from the support portion 5 is S211, and the distance between the two endpoints of the second notch 42 near the support portion 5 is S212, where S211≤S212. Based on this arrangement, by making the distance between the two endpoints of the second notch 42 near the support portion 5 larger, the distance between the support portion 5 and the non-notch portion of the third sub-partition 313 can be increased, thereby further reducing the difficulty of setting up the support portion 5.
[0167] For example, the length of the support portion 5 in the fourth direction h14 is S5, where S211≤S5≤S112. In this way, while avoiding mutual interference between the third sub-partition 321 and the support portion 5, the distance between the support portion 5 and the second sub-pixel 221 can be reduced. For example, the area of the second sub-pixel 221 can be set as large as possible to extend its lifespan and improve the display effect of the display panel 100.
[0168] For example, in combination Figure 1 , Figure 8 and Figure 18 As shown, the second sub-pixel 221 also includes multiple second sub-edges E21, and two adjacent second sub-edges E21 form the apex A of the second sub-pixel 221. Figure 1 , Figure 8 and Figure 18 Four second-level edges E21 are set in the second sub-pixel 221, three of which include straight line segments and the other includes curved line segments as an illustration.
[0169] like Figure 1 , Figure 8 and Figure 18 As shown, the third sub-partition 321 also includes a second notch 42 corresponding to the second edge E21; the distance between the two endpoints of the second notch 42 corresponding to the second edge E21 is S213, and the distance between the two endpoints of the second notch 42 corresponding to the apex A of the second sub-pixel 221 and close to the support 5 is S212; wherein, S213≤S212. Based on this arrangement, by making the distance between the two endpoints of the second notch 42 close to the support 5 larger, the distance between the support 5 and the third sub-partition 321 can be increased, thereby further reducing the difficulty of setting up the support 5. In addition, by making the distance between the two endpoints of the second notch 42 corresponding to the second edge E21 as small as possible, the area of the region where lateral leakage current occurs around the second sub-pixel 221 can be reduced, thereby further improving the reliability of the display panel.
[0170] For example, such as Figure 18 As shown, the length of the support portion 5 in the fourth direction h14 is S5, where S213≤S5≤S212. In this way, while avoiding mutual interference between the third sub-partition 321 and the support portion 5, the distance between the support portion 5 and the second sub-pixel 221 can be reduced. For example, the area of the second sub-pixel 221 can be set as large as possible to extend its lifespan and improve the display effect of the display panel 100.
[0171] For example, in combination Figure 16 and Figure 19 As shown, Figure 19 for Figure 16 An enlarged schematic diagram of a second sub-pixel, a third sub-partition, and a support portion is shown. The second sub-pixel 221 includes a protrusion 201 and a main body 202. At least a portion of the arc segment C is located on the side of the second sub-pixel 221 near the support portion 5. Figure 19 The diagram illustrates the placement of a portion of the arc segment C on the side of the second sub-pixel 221 near the support portion 5. This placement means that the line connecting the centroid of the virtual circumscribed quadrilateral of the second sub-pixel 221 and the centroid of the support portion 5 passes through the arc segment C. In this embodiment, the second partition portion 32 includes a second edge E2, which is located between at least a portion of the arc segment C and the support portion 5.
[0172] Based on this configuration, on the one hand, the formation of a second gap at the second edge E2 can be avoided, thereby utilizing the portion of the second partition 32 located at the second edge E2 to suppress the leakage current from the outer sub-pixel affecting the second sub-pixel 221, preventing the formation of a leakage current channel at that location. This improves the consistency of the leakage current transmission path between this area and other areas without the support portion 5. For example, improving the consistency of the leakage current transmission path around the second sub-pixel 221 and the second sub-pixel 222 is beneficial to improving the display uniformity of the display panel.
[0173] On the other hand, by setting the second edge E2 at this position of the second partition 32 instead of setting the corner structure protruding towards the support 5, the distance between the second partition 32 and the support 5 can be avoided. This not only reduces the difficulty of setting the second partition 32 and the support 5, but also eliminates the need to reduce the area of the support 5, thus ensuring the support effect of the support 5.
[0174] In another alternative implementation, such as Figure 20 As shown, Figure 20 This is a schematic diagram of another display panel provided in an embodiment of the present invention. When the second edge E2 is provided in the second partition 32, the first sub-pixel 21 can also be set as a quadrilateral in this embodiment of the present invention. Figure 20 and Figure 16 The only difference is the shape of the first sub-pixel 21; the other settings can be the same.
[0175] For example, when setting the second Jiazi pixel 221, Figure 21 and Figure 22 As shown, Figure 21 This is a schematic diagram of yet another display panel provided in an embodiment of the present utility model. Figure 22 for Figure 21This is an enlarged schematic diagram of a second sub-pixel, a third sub-partition, and a support portion. In this embodiment, the main body 202 can be configured to include a first straight line segment L1 and a second straight line segment L2, which intersect. One end of an arc segment C is connected to the first straight line segment L1, and the other end of the arc segment C is connected to the second straight line segment L2. The first straight line segment L1 and the second straight line segment L2 intersect at a first vertex B. That is, the shape of the second sub-pixel 221 is designed to be approximately teardrop-shaped.
[0176] Optional, such as Figure 21 As shown, the third sub-partition 321 includes a second edge E2, which is located between at least a portion of the arc segment C and the support portion 5.
[0177] It should be noted that, Figure 21 The design of the second sub-pixel 22 as an approximate teardrop shape and the design of the first sub-pixel 21 as a quadrilateral shape are only for illustration. When the first sub-pixel 21 is designed as a structure including a protrusion and a main body, the first sub-pixel 21 can also be designed as an approximate teardrop shape in this embodiment of the invention, which will not be illustrated in the accompanying drawings.
[0178] like Figure 23 and Figure 24 As shown, Figure 23 This is a schematic diagram of yet another display panel provided in an embodiment of the present utility model. Figure 24 for Figure 23 An enlarged schematic diagram of a second sub-pixel, a third sub-partition, and a support portion, wherein the shape of the second sub-pixel 221 and... Figure 21 The same as what is shown, and Figure 21 The difference is that, in Figure 23 and Figure 24 In addition to the second edge E2 mentioned above, the second partition portion 32 also includes a third edge E3, which is located on the side of the second sub-pixel 221 away from the second edge E2.
[0179] Based on this configuration, on the one hand, the formation of a second gap at the third edge E3 can be avoided, thereby utilizing the portion of the second partition 32 located at the third edge E3 to suppress the leakage current from the outer sub-pixel affecting the second sub-pixel 221, preventing the formation of a leakage current channel at that location. This improves the consistency of the leakage current transmission path between this area and other areas without the support portion 5. For example, improving the consistency of the leakage current transmission path around the second sub-pixel 221 and the second sub-pixel 222 is beneficial to improving the display uniformity of the display panel.
[0180] On the other hand, by setting the third edge E3 at this position instead of setting the corner structure protruding away from the second sub-pixel 221 on the third direction h13, the area defined by the outline of the second partition 32 can be reduced, thereby leaving space for the setting of sub-pixels.
[0181] For example, such as Figure 23 and Figure 24 As shown, in this embodiment of the invention, a fourth edge E4 can also be provided in the second partition portion 32. The fourth edge E4 is located on the side of the second sub-pixel 22 away from the first vertex B. Based on this arrangement, the second partition portion 32 can avoid having a angular structure protruding from the arc segment C of the second sub-pixel 22 in the fourth direction h14 away from the second sub-pixel 221, which is beneficial to further reduce the area defined by the outline of the second partition portion 32.
[0182] For example, continue to refer to Figure 19 As shown, the second sub-pixel 221 also includes multiple second sub-edges E21, and two adjacent second sub-edges E21 form the apex A of the second sub-pixel 221. The third sub-partition 321 also includes a second notch 42 corresponding to the second sub-edge E21. The second sub-edge E21 can be a straight line segment or an arc segment. Figure 19 The second sub-pixel 221 includes four second sub-edges E21, three of which include straight line segments and the other includes an arc segment as an illustration. The third sub-partition 321 includes three second gaps 42 corresponding to the three straight line segments and one second gap 42 corresponding to one arc segment as an illustration.
[0183] like Figure 19 As shown, the distance between the two endpoints of the second notch 42 corresponding to the second edge E21 is S213, and the length of the second edge E2 is S22, where S213 ≤ S22. Based on this arrangement, by making the length of the second edge E2 near the support 5 larger, the distance between the support 5 and the third sub-partition 321 can be increased, thereby further reducing the difficulty of setting up the support 5. In addition, by making the distance between the two endpoints of the second notch 42 corresponding to the second edge E21 as small as possible, the area of the region where lateral leakage current occurs can be reduced, thereby further improving the reliability of the display panel.
[0184] For example, such as Figure 19As shown, the length of the support portion 5 in the fourth direction h14 is S5, where S213≤S5≤S22. In this way, while avoiding mutual interference between the third sub-partition 321 and the support portion 5, the distance between the support portion 5 and the second sub-pixel 221 can be reduced. For example, the area of the second sub-pixel 221 can be set as large as possible to extend its lifespan and improve the display effect of the display panel 100.
[0185] For example, continue to refer to Figure 16 As shown, the second sub-pixel 22 includes a protrusion 201 and a main body 202; the protrusion 201 includes a fifth edge E5 away from the main body 202; the second sub-pixel 22 includes a virtual circumscribed quadrilateral; the second sub-pixel 22 includes a fifth type sub-pixel 223, a sixth type sub-pixel 224, a seventh type sub-pixel 225, and an eighth type sub-pixel 226; wherein, the centroid of the orthographic projection of the virtual circumscribed quadrilateral of the fifth type sub-pixel 223 onto the plane where the substrate is located points to the center of the fifth edge E5 in a direction parallel to the first direction h11; the virtual circumscribed quadrilateral of the sixth type sub-pixel 224... The centroid of the orthographic projection of the seventh sub-pixel 225 onto the plane of the substrate points in a direction parallel to the center of the fifth edge E5, which is parallel to the opposite direction of the first direction h11. The centroid of the orthographic projection of the virtual circumscribed quadrilateral of the eighth sub-pixel 226 onto the plane of the substrate points in a direction parallel to the center of the fifth edge E5, which is parallel to the opposite direction of the second direction h12. The center of the fifth edge E5 refers to the midpoint of the line connecting the two endpoints of the fifth edge E5.
[0186] When arranging the aforementioned fifth type sub-pixel 223, sixth type sub-pixel 224, seventh type sub-pixel 225, and eighth type sub-pixel 226, for example, as follows: Figure 16 As shown, in any row of sub-pixels, such as in the (m+1)th row of sub-pixels 11_m+1, this embodiment of the invention allows the fifth type of sub-pixels 223, the seventh type of sub-pixels 225, the sixth type of sub-pixels 224, and the eighth type of sub-pixels 226 to be arranged alternately along the first direction h11; in any column of sub-pixels, such as in the (n+1)th column of sub-pixels 11_n+1, this embodiment of the invention allows the fifth type of sub-pixels 223, the eighth type of sub-pixels 226, the sixth type of sub-pixels 224, and the seventh type of sub-pixels 225 to be arranged alternately along the second direction h12. Based on this arrangement, the second sub-pixels 22 of the protrusions 201 with different orientations can be evenly distributed in the display panel, which is beneficial to improving display uniformity.
[0187] When setting the second sub-pixel 22, for example, as follows: Figure 25 and Figure 12C As shown, Figure 25 This is a schematic diagram of yet another display panel provided in an embodiment of the present utility model. Figure 12C It can be seen as Figure 25 An enlarged schematic diagram of the second sub-pixel 22 is shown. The second sub-pixel 22 includes a protrusion 201 and a main body 202. The arc segment C includes a first arc segment C1 and a second arc segment C2. The edge of the protrusion 201 away from the main body 202 also includes a straight line segment L connecting the first arc segment C1 and the second arc segment C2. The length of the first arc segment C1 is greater than the length of the second arc segment C2. The two endpoints of the first arc segment C1 are P1 and P2, the two endpoints of the second arc segment C2 are P3 and P4, and the two endpoints of the straight line segment L are P2 and P3. For example, as shown... Figure 12C As shown, the distance between P1 and P2 in the first direction h11 is d1, and the distance between P3 and P4 in the first direction h11 is d2, where d1 ≠ d2. Based on this setting, the flexibility of the shape design of the second sub-pixel 22 can be improved.
[0188] like Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 16 , Figure 21 and Figure 23 As shown, the second sub-pixel 22 further includes a second sub-pixel 222, and the second sub-pixel 222 and its adjacent first sub-pixel 21 do not include a support portion 5. In this embodiment of the invention, the second sub-pixel 222 and its adjacent first sub-pixel 21 in the third direction h13 do not include a support portion 5. Furthermore, the second sub-pixel 222 and its adjacent first sub-pixel 21 in the fourth direction h14 do not include a support portion 5.
[0189] For example, such as Figure 7 and Figure 10 As shown, the second sub-pixel 222 includes a apex corner A, and the second partition portion 32 includes a fourth sub-partition portion 322. The fourth sub-partition portion 322 at least partially surrounds the second sub-pixel 222, and the fourth sub-partition portion 322 includes a second notch 42 corresponding to the apex corner A of the second sub-pixel 222. The provision of this second notch 42 can ensure good connection of the second electrode located outside the apex corner A of the second sub-pixel 222.
[0190] For example, such as Figure 1 , Figure 8 , Figure 9 , Figure 11 , Figure 16 , Figure 21 and Figure 23As shown, the second sub-pixel 222 also includes multiple second edges E22, with two adjacent second edges E22 forming the apex A of the second sub-pixel 222. The fourth sub-partition 322 also includes a second notch 42 corresponding to the second edge E22; the distance between the two endpoints of the second notch 42 corresponding to the second edge E22 is S222. Figure 18 As shown, the distance between the two endpoints of the second notch 42, which corresponds to the apex A of the second sub-pixel 221 and is close to the support portion 5, is S212. In this embodiment of the invention, S222 ≤ S212. By making the distance between the two endpoints of the second notch 42 near the support portion 5 larger, this embodiment of the invention can increase the distance between the support portion 5 and the third sub-partition 321, thereby further reducing the difficulty of setting up the support portion 5. In addition, by making the distance between the two endpoints of the second notch 42, which corresponds to the second edge E22, as small as possible, the area of the region where lateral leakage current occurs around the second sub-pixel 222 can be reduced, thereby further improving the display effect of the display panel.
[0191] Optionally, in this embodiment of the invention, S222 can be set to S213.
[0192] For example, in this embodiment of the present invention, S212 = 2 × S213 = 2 × S222. Based on this setting, combined with... Figure 1 and Figure 8 As shown, when the third sub-partition 321 is configured to include two second notches 42 respectively corresponding to different second A edges E21 and one second notch 42 corresponding to the top corner A of the second A sub-pixel 221, and the fourth sub-partition 322 is configured to include four second notches 42 respectively corresponding to different second B edges E22, the area ratio of the second notch 42 around the second A sub-pixel 221 to the area ratio of the second partition 32 can be the same as that of the second notch 42 around the second B sub-pixel 222 to the area ratio of the second partition 32. This can make the brightness of the second A sub-pixel 221 and the second B sub-pixel 222 more consistent, and improve the display consistency of the display panel in different areas.
[0193] For example, continue to refer to Figure 9 and Figure 10 As shown, the second sub-pixel 22 includes the second sub-pixel 221 and the second sub-pixel 222, and the second partition portion 32 includes the second partition portion 323 and the second partition portion 324. The second partition portion 323 at least partially surrounds the second sub-pixel 221, and the second partition portion 324 at least partially surrounds the second sub-pixel 222. For example, the second partition portion 323 includes the third sub-partition portion 321, and the second partition portion 324 includes the fourth sub-partition portion 322.
[0194] In this embodiment of the invention, the shape of the second partition portion 323 is the same as the shape of the second partition portion 324; the length of the second partition portion 323 is the same as the length of the second partition portion 324; the width of the second partition portion 323 is the same as the width of the second partition portion 324; wherein, the length direction of the second partition portion 323 and the second partition portion 324 is parallel to their respective extension direction, and the width direction is perpendicular to their respective extension direction. The distance between the two endpoints of the second notch 42 in the second partition portion 323 is the same as the distance between the two endpoints of the second notch 42 in the second partition portion 324.
[0195] like Figure 9 and Figure 10 As shown, the second sub-pixel 221 can be superimposed on the second sub-pixel 222 by translation. The second partition portion 323 can be superimposed on the second partition portion 324 by translation. The second notch 42 in the second partition portion 323 can be superimposed on the second notch 42 in the second partition portion 324 by translation.
[0196] Based on this configuration, the distribution patterns of the second partition portion 32 and the second notch 42 around the second sub-pixel 221 and the second sub-pixel 222, which have different positional relationships with the support portion 5, can be made the lateral leakage current around the second sub-pixel 221 and the second sub-pixel 222 tend to be consistent, and the morphology of the second electrode of the second sub-pixel 221 and the second electrode around the second sub-pixel 222 tend to be consistent, which is beneficial to improving the display uniformity of the display panel.
[0197] For example, such as Figure 10 As shown, in this embodiment of the utility model, the second notch 42 in the second partition 323 can be set to correspond to the top corner A of the second sub-pixel 221, and the second notch 42 in the second partition 324 can be set to correspond to the top corner A of the second sub-pixel 222.
[0198] Or, such as Figure 9 As shown, in this embodiment of the present invention, the second notch 42 in the second partition 323 can be configured to correspond to the edge of the second sub-pixel 221; and the second notch 42 in the second partition 324 can be configured to correspond to the edge of the second sub-pixel 222.
[0199] Optional, based on Figure 9 In this configuration, the widths of the second partition 323 and the second partition 324 can be appropriately compressed to avoid mutual interference between the second partition 323 and the support 5. Optionally, the width W of the second partition 323 and the second partition 324 can satisfy 1.5μm≤W≤3.5μm.
[0200] For example, such as Figure 7 As shown, no partition is provided around the third sub-pixel 23. Based on this arrangement, the second electrode of the sub-pixel ( Figure 7 The signal transmitted (not shown) is input from the display panel in the bezel area on both sides of the third direction h13 and is transmitted along the third direction h13 to form a current transmission channel, which helps to reduce the voltage drop of the signal transmitted by the second electrode during the transmission process and improve the display effect. Figure 7 One of the transmission paths of the aforementioned signal is illustrated by a straight line with an arrow.
[0201] Moreover, such as Figure 7 As shown, within the display panel, the number of third sub-pixels 23 per unit area is greater than the number of first sub-pixels 21 and second sub-pixels 22. This embodiment of the invention eliminates the need for partitions around the third sub-pixels 23, and can be implemented according to… Figure 7 The method shown provides the aforementioned first partition 31 and second partition 32 around the first sub-pixel 21 and the second sub-pixel 22, respectively. This effectively improves the issue of light leakage from the first sub-pixel 21. For example, when the first sub-pixel 21 is set as a red sub-pixel, the second sub-pixel 22 as a blue sub-pixel, and the third sub-pixel 23 as a green sub-pixel, in related technologies, when the display panel displays a blue image, the light leakage from the red sub-pixel causes significant changes in the color coordinates of the blue image under different brightness levels, resulting in a reddish visual effect. Based on... Figure 7 The provided configuration effectively suppresses the phenomenon of red sub-pixels illuminating under blue backgrounds. Furthermore, it reduces the area occupied by the partition 3, increases the conduction path of the signal transmitted by the second electrode, further reduces voltage drop during signal transmission, lowers power consumption of the display panel, and improves display uniformity.
[0202] For example, such as Figure 1 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 16 , Figure 21 , Figure 23 , Figure 25 , Figure 26 and Figure 27 As shown, Figure 26 and Figure 27The schematic diagram shows two other display panels provided in this embodiment of the present invention. The partition portion 3 further includes a third partition portion 33, which at least partially surrounds the third sub-pixel 23 and includes at least one third notch 43. The arrangement of the third partition portion 33 can extend or block the lateral leakage transmission path between the third sub-pixel 23 and adjacent sub-pixels of different colors, such as the first sub-pixel 21 or the second sub-pixel 22, thereby improving the display effect of the display panel. The arrangement of the third notch 43 can improve the connection reliability of the second electrode at this location, thereby improving the display uniformity of the display panel.
[0203] For example, in combination Figure 10 , Figure 11 , Figure 26 and Figure 28 As shown, Figure 28 This is an enlarged schematic diagram of a third sub-pixel and a third partition portion provided in an embodiment of the present invention. The third sub-pixel 23 includes a virtual circumscribed quadrilateral 20. The centroid Q3 of the orthographic projection of the virtual circumscribed quadrilateral 20 of the third sub-pixel 23 onto the plane of the substrate 1 points in a direction parallel to the center Q4 of the third notch 43, which is parallel to either the first direction h11 or the second direction h12. The center of the third notch 43 refers to the midpoint of the line connecting the two endpoints of the third partition portion 33 forming the third notch 43.
[0204] Figure 10 The third partition 33 includes two third notches 43. The centroid of the virtual outer quadrilateral of a portion of the third sub-pixel 23 projected onto the plane of the substrate 1 points in a direction parallel to the center of one of the third notches 43, which is parallel to the second direction h12. The centroid of the virtual outer quadrilateral of another portion of the third sub-pixel 23 projected onto the plane of the substrate 1 points in a direction parallel to the center of the third notch 43, which is parallel to the first direction h11.
[0205] Figure 11 The third partition 33 includes two third notches 43 arranged along the first direction h11. The centroid of the virtual circumscribed quadrilateral of the third sub-pixel 23 projected onto the plane of the substrate 1 points to the center of one of the third notches 43 in a direction parallel to the first direction h11. The centroid of the virtual circumscribed quadrilateral 20 of the third sub-pixel 23 projected onto the plane of the substrate 1 points to the center of the other third notch 43 in a direction parallel to the opposite direction of the first direction h11.
[0206] Figure 26The third partition 33 includes a third notch 43. The centroid of the virtual outer quadrilateral of a portion of the third sub-pixel 23 projected onto the plane of the substrate 1, pointing towards the center of the third notch 43, is parallel to the second direction h12. The centroid of the virtual outer quadrilateral of another portion of the third sub-pixel 23 projected onto the plane of the substrate 1, pointing towards the center of the third notch 43, is parallel to the first direction h11. (For comparison...) Figure 26 and Figure 10 It can be seen that the only difference between the two is the number of the third gap 43; the other settings are the same. Figure 10 In the middle, the third partition 43 includes two third notches, in Figure 26 In the middle, the third partition 43 includes only a third notch 43.
[0207] Figure 28 The third partition 33 includes a third notch 43, and the centroid Q3 of the orthographic projection of the virtual outer quadrilateral 20 of the third sub-pixel 23 onto the plane of the substrate 1 points to the center Q4 of the third notch 43 in a direction parallel to the first direction h11 as an illustration.
[0208] Continue to refer to Figure 11 The first partition 31 includes two first notches 41 corresponding to the edges of the first sub-pixel 21, and the second partition 32 includes two second notches 42 corresponding to the edges of the second sub-pixel 22. Combining the third partition 33 and the third notches 43 described above, the areas of the partitions and notches can be better balanced, thereby better balancing the effects of suppressing sub-pixel overexposure and reducing the impedance of the second electrode. Furthermore, as... Figure 11 As shown, the two first notches 41 corresponding to the first sub-pixel 21 are arranged along the second direction h12, the two second notches 42 corresponding to the second sub-pixel 22 are arranged along the second direction h12, and the two third notches 43 corresponding to the third sub-pixel 23 are arranged along the first direction h11. Since the first direction h11 intersects with the third direction h13 and the fourth direction h14 respectively, and the second direction h12 also intersects with the third direction h13 and the fourth direction h14 respectively, the impedance of the second electrode in the third direction h13 and the fourth direction h14 can be reduced, which is beneficial to reduce the voltage drop of the signal transmitted by the second electrode in the third direction h13 and the fourth direction h14, and reduce the power consumption of the display panel.
[0209] In one alternative implementation, such as Figure 26 As shown, in this embodiment of the invention, only one third notch 43 can be provided in the third partition portion 33. For two adjacent third sub-pixels 23, as... Figure 26As shown, in this embodiment of the present invention, the centroid of the orthographic projection of the virtual outer quadrilateral of one of the third sub-pixels 23 onto the plane of the substrate 1 is parallel to the first direction h11, and the centroid of the orthographic projection of the virtual outer quadrilateral of the other third sub-pixel 23 onto the plane of the substrate 1 is parallel to the second direction h12, so as to improve the uniformity of the distribution of the third notches 43 with different orientations in the display panel, thereby improving the transmission consistency of the signal transmitted by the second electrode in the display panel.
[0210] In another alternative implementation, such as Figure 1 , Figure 8 , Figure 9 , Figure 10 , Figure 16 , Figure 23 , Figure 25 and Figure 27 As shown, in this embodiment of the invention, at least two third notches 43 may be provided in the third partition portion 33. For two third sub-pixels 23 adjacently arranged on the third direction h13, in this embodiment of the invention, the third notches 43 around one third sub-pixel 23 and the third notches 43 around the other third sub-pixel 23 may be arranged along the aforementioned third direction h13; the two third notches 43 around one third sub-pixel 23 may be arranged along the fifth direction h15, and the two third notches 43 around the other third sub-pixel 23 may be arranged along the sixth direction h16. Based on this arrangement, the uniformity of the distribution of third notches 43 in different orientations in the display panel can be improved, thereby improving the transmission consistency of the signal transmitted by the second electrode in the display panel.
[0211] For example, such as Figure 10 and Figure 27 As shown, in this embodiment of the invention, the fifth direction h15 can be made parallel to the first direction h11, and the sixth direction h16 can be made parallel to the second direction h12.
[0212] Optionally, in this embodiment of the invention, the number of first notches 41 included in the first partition portion 31 and the number of third notches 43 included in the third partition portion 33 can be the same to balance the brightness of the first sub-pixel 21 and the third sub-pixel 23 and improve the display effect of the display panel. Figure 1 , Figure 9 , Figure 10 , Figure 11 , Figure 16 , Figure 20 , Figure 21 , Figure 23 and Figure 25As shown, two first gaps 41 are provided in the first partition portion 31 surrounding the first sub-pixel 21, and two third gaps 43 are also provided in the third partition portion 33 surrounding the third sub-pixel 23 as an illustration.
[0213] When the first sub-pixel 21 is a red sub-pixel, the second sub-pixel 22 is a blue sub-pixel, and the third sub-pixel 23 is a green sub-pixel, the inventors... Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 26 and Figure 27 The scheme shown and Figure 29 and Figure 30 The two embodiments shown were subjected to simulation tests. Figure 29 and Figure 30 and Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 26 and Figure 27 The pixel arrangement follows the same pattern. (And...) Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 26 and Figure 27 The difference is that, in Figure 29 In this configuration, there are no first, second, or third partition sections. Figure 30 In this configuration, the first and third partition sections are not provided; only the second partition section is provided.
[0214] The simulation results are shown in Table 1 below. R@B_1 represents the ratio of the light intensity of the red subpixel to the light intensity of the blue subpixel when the display panel is displaying a blue image. The larger the value, the more severe the light smearing by the red subpixel. G@B_1 represents the ratio of the light intensity of the green subpixel to the light intensity of the blue subpixel when the display panel is displaying a blue image. The larger the value, the more severe the light smearing by the green subpixel.

[0217] As can be seen from Table 1, with Figure 29 and Figure 30 Compared to the methods provided, the embodiments of this utility model provide... Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 26 and Figure 27 The solutions shown can all effectively suppress the red and green sub-pixels from shining up when the blue sub-pixel is lit.
[0218] In addition, the inventor also... Figure 1 , Figure 9 , Figure 10 and Figure 26 The scheme shown was used to simulate the phenomenon of red subpixel light stealing under a green screen, and the results are shown in Table 2 below. R@G_1 represents the proportion of the light intensity of the red subpixel to the light intensity of the green subpixel when the display panel is displaying a green screen; the larger the value, the more severe the light stealing by the red subpixel.

[0221] As can be seen from Table 2, the embodiments of this utility model provide Figure 1 , Figure 9 , Figure 10 and Figure 26 The solutions shown can all suppress the red sub-pixels from lighting up when the green sub-pixels are lit. Specifically, based on... Figure 26 The scheme shown can significantly suppress the red sub-pixel from shining by making the third partition portion 33 include only one third notch 43, reducing the number of third notches 43 and increasing the length of the non-notch portion in the third partition portion 33.
[0222] In addition, the inventor also... Figure 1 , Figure 9 , Figure 10 and Figure 26 The display uniformity of the illustrated scheme was simulated, and the results are shown in Table 3 below.

[0225] As can be seen from Table 3, with Figure 1 Compared to the scheme shown, under the blue screen, the embodiment of this utility model provides... Figure 9 , Figure 10 and Figure 26 All the solutions shown can improve the brightness consistency of green sub-pixels. Moreover, regardless of... Figure 1 The proposed solution is still... Figure 9 , Figure 10 and Figure 26 The scheme shown exhibits high brightness consistency for red subpixels within a green background.
[0226] In addition, the inventor also... Figure 1 , Figure 9 , Figure 10 and Figure 26 The resistance of the second electrode in the illustrated scheme was simulated, and the results are shown in Table 4 below. Here, RX represents the resistance of the second electrode in the aforementioned third direction, and RY represents the resistance of the second electrode in the aforementioned fourth direction.

[0229] As can be seen from Table 4, the embodiments of this utility model provide Figure 1 , Figure 9 , Figure 10 and Figure 26 The solutions shown can all reduce the resistance of the second electrode, especially on the third-direction h13, based on Figure 1 and Figure 9 The solutions provided can all reduce the resistance of the second electrode to below 20Ω / □, which can significantly reduce the signal loss during transmission, improve display uniformity, and reduce the power consumption of the display panel.
[0230] For example, such as Figure 31 As shown, Figure 31 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. The display panel 100 further includes multiple scan lines 91 and multiple data lines 92. The scan lines 91 extend along the third direction h13, and the multiple scan lines 91 are arranged along the fourth direction h14. The data lines 92 extend along the fourth direction h14, and the multiple data lines 92 are arranged along the third direction h13.
[0231] like Figure 31 As shown, scan line 91 is electrically connected to a plurality of sub-pixels 2 arranged along the third direction h13, and data line 92 is electrically connected to a plurality of sub-pixels 2 arranged in the fourth direction h14.
[0232] For two adjacent scan lines 91, such as Figure 31As shown, one scan line 91 is electrically connected to a plurality of first sub-pixels 21 and a plurality of third sub-pixels 23 arranged alternately along a third direction h13, and the other scan line 91 is electrically connected to a plurality of second sub-pixels 22 arranged alternately along a fifth direction h15. Furthermore, the sub-pixels 2 connected to adjacent scan lines 91 are staggered in the sixth direction h16. For adjacent data lines 92, one data line 92 is electrically connected to a plurality of first sub-pixels 21 and a plurality of third sub-pixels 23 arranged alternately along the sixth direction h16, and the other data line 92 is electrically connected to a plurality of second sub-pixels 22 arranged alternately along the sixth direction h16. Furthermore, the sub-pixels 2 connected to adjacent data lines 92 are staggered in the fifth direction h15. When the display panel 100 is operating, the data lines 92 provide data voltage, and the plurality of scan lines 91 sequentially provide control signals to control the charging of the sub-pixels 2, so that the corresponding sub-pixels 2 are charged with the data voltage provided by the data lines 92 and illuminated at the required brightness.
[0233] Optional, such as Figure 32 As shown, Figure 32 This is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention. The light-emitting layer 203 includes a first light-emitting layer 2031 and a second light-emitting layer 2032. The second light-emitting layer 2032 is located on the side of the first light-emitting layer 2031 away from the substrate 1. The orthographic projection of the second light-emitting layer 2032 onto the plane of the substrate 1 at least partially overlaps with the orthographic projection of the first light-emitting layer 2031 onto the plane of the substrate 1. At least a portion of the first light-emitting layer 2031 and the second light-emitting layer 2032 are located within the opening 80. For example, both the first light-emitting layer 2031 and the second light-emitting layer 2032 can be fabricated using a fine metal mask (FMM). The first light-emitting layer 2031 is deposited within the opening 80 of the pixel definition layer 8 and can partially extend outside the opening 80. The first light-emitting layers 2031 of different sub-pixels 2 are independent of each other. The second light-emitting layers 2032 of different sub-pixels 2 are independent of each other.
[0234] For example, the first light-emitting layer 2031 and the second light-emitting layer 2032 may have the same or different light-emitting colors.
[0235] like Figure 32 As shown, sub-pixel 2 also includes a charge generation layer 205, which is located between the first light-emitting layer 2031 and the second light-emitting layer 2032.
[0236] For example, such as Figure 32As shown, the charge generation layer 205 can be disconnected at the location of the partition 3. Alternatively, the charge generation layer 205 can also be provided with a protrusion at the partition 3 away from the substrate 1 to increase the transmission path of lateral leakage current in the charge generation layer 205. Since the charge generation layer 205 has high conductivity, if the partition 3 is not provided, the charge will migrate laterally between two adjacent sub-pixels 2 through the charge generation layer 205, which can easily cause crosstalk between two adjacent sub-pixels 2, resulting in color shift in the display panel. In particular, the charge generation layer 205 can easily cause crosstalk between sub-pixels of different colors at low brightness, resulting in low grayscale color shift. Based on the configuration provided by this embodiment, the low grayscale color shift problem can be weakened, and the display effect of the display panel can be improved.
[0237] The display panel 100 provided in this embodiment of the present invention improves the brightness of the sub-pixels 2 and reduces the power consumption of the display panel 100 by designing the sub-pixels 2 as a series structure including a first light-emitting layer 2031 and a second light-emitting layer 2032 stacked together, thereby increasing the lifespan of the display panel 100. Furthermore, by providing the aforementioned partition portion 3 in the display panel 100, this embodiment of the present invention can suppress or isolate the lateral leakage current between two adjacent sub-pixels 2, overcoming crosstalk between adjacent sub-pixels 2 caused by the high conductivity of the charge generation layer 205, thus improving the display quality of the display panel 100.
[0238] Optionally, the charge generation layer 205 may include at least one of an N-type charge generation layer and a P-type charge generation layer.
[0239] Based on the same inventive concept, this utility model embodiment also provides a display device, such as... Figure 33 As shown, Figure 33 This is a schematic diagram of a display device provided in an embodiment of the present invention. The display device includes the display panel 100 described above.

Of course, Figure 33 The display device shown is for illustrative purposes only.
