Description

[Technical Field]

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

[0002] In recent years, with the continuous development of display technology, the screen ratio of display panels has become larger and larger, bringing users a more immersive visual experience.

[0003] To further narrow the bottom bezel width, a technique has been proposed that involves placing some fanout lines inside the display area (fanout in AA, FIAA). This technique requires introducing some connecting lines within the display area. However, introducing these connecting lines can lead to issues such as screen muting when the screen is off. [Summary of the Invention]

[0004] In view of this, embodiments of the present invention provide a display panel and a display device to improve the screen-off mura phenomenon.

[0005] On one hand, embodiments of the present invention provide a display panel, including:

[0006] Display area and pad area;

[0007] Multiple data lines located in the display area;

[0008] A first wiring layer located in the display area includes multiple data connection lines and multiple trace segments, wherein the multiple data connection lines connect the multiple data lines and are used to transmit the data voltage provided by the pad area to the multiple data lines connected thereto, and at least a portion of the trace segments are spaced apart from the data connection lines by a first break.

[0009] A cover layer is located on the side of the first wiring layer facing the light emission direction of the display panel. The cover layer includes a first cover portion and a second cover portion. In a direction perpendicular to the plane where the display panel is located, the first cover portion overlaps with the first break, and the second cover portion overlaps with the data connection line and the wiring segment.

[0010] Wherein, the thickness of the first covering part is less than the thickness of at least a portion of the second covering part.

[0011] The above technical solution has the following beneficial effects:

[0012] In the above technical solution, by setting a cover layer on the first wiring layer and designing the film thickness of the cover layer at different locations differently, the difference in film thickness of the cover layer can be used to weaken the difference in reflectivity at different locations caused by the first break. For example, the first cover portion overlapping the first break in the cover layer can be made to have a smaller film thickness, thereby reducing the degree of absorption or blocking of ambient light by the first cover portion. This allows some ambient light to pass through the first cover portion and be incident on the first break, and then reflected back through the sidewalls of the wiring segment and the data connection line, increasing the reflectivity at the location of the first break. This reduces the difference in reflectivity between the first wiring layer at the first break and where the first break is not set, effectively weakening the screen-off mura phenomenon caused by the first break.

[0013] On the other hand, embodiments of the present invention provide a display panel, including:

[0014] The display area includes a display area and a pad area, wherein the display area includes a first display area and a second display area, and the first display area is located on the side of the second display area closer to the pad area;

[0015] Multiple data lines located in the display area;

[0016] A first wiring layer located in the display area, the first wiring layer including multiple data connection lines and multiple trace segments, wherein the multiple data connection lines are located in the first display area, the multiple data connection lines connect the multiple data lines, and are used to transmit the data voltage provided by the pad area to the multiple data lines connected thereto, the trace segments are located in the first display area and the second display area, and at least a portion of the trace segments are spaced apart from the data connection lines by a first break;

[0017] A cover layer is located on the side of the first wiring layer facing the light emission direction of the display panel. The cover layer includes a fifth cover portion and a sixth cover portion. The fifth cover portion is located in the second display area and overlaps with a portion of the wiring segments in the second display area in a direction perpendicular to the plane of the display panel. The sixth cover portion is located in both the first and second display areas and overlaps with the first break, the data connection line, and the wiring segments in the first display area in a direction perpendicular to the plane of the display panel. The sixth cover portion also overlaps with the remaining wiring segments in the second display area.

[0018] The thickness of the fifth covering part is greater than the thickness of the sixth covering part.

[0019] The above technical solution has the following beneficial effects:

[0020] In the above technical solution, by setting a cover layer on the first wiring layer and differentiating the film thickness of the cover layer at different locations, the risk of the mura phenomenon caused by the first break being visible to the human eye can be reduced by utilizing the difference in film thickness of the cover layer. Specifically, in this embodiment of the invention, by increasing the film thickness of the fifth cover portion in the second display area, the difference in film thickness between the fifth and sixth cover portions can be used to create a difference in reflectivity at different locations in the second display area, so that a mura pattern also exists in the second display area. In this way, the mura pattern that originally existed only in the first display area due to the first break can be expanded into a full-screen mura pattern. Compared with a partial mura pattern, this full-screen mura pattern is less likely to be visible to the human eye, thus reducing the risk of the mura being recognized by the human eye.

[0021] In another aspect, embodiments of the present invention provide a display device, including the aforementioned display panel. [Attached Image Description]

Detailed Implementation Methods

[0068] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0069] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0070] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0071] 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, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0072] To enable normal image display on the display panel, multiple data lines are installed in the display area. These data lines are typically led to pins via fan-out lines extending within the bottom bezel, thus achieving electrical connection with the pins. However, the current arrangement of the fan-out lines in the bottom bezel area is not conducive to optimizing the size design of the bottom bezel, resulting in a relatively large bezel width for the display panel.

[0073] Taking a display panel with rounded rectangles as an example, such as Figure 1 As shown, Figure 1 This is a schematic diagram of a display panel in the related technology. The display panel includes a display area 101 and a lower border 102. The lower border 102 includes a corner area 103. The corner area 103 is located at the top corner of the display panel and is also called the R-corner area. The edge of the corner area 103 can be a curved edge.

[0074] The display area 101 contains multiple data lines (Data). The ends of the Data lines near the lower side of the display area 101 are connected to fan-out lines 104 in the lower bezel 102, and then led to pins via the fan-out lines 104. However, for the Data lines near the edge of the display area 101, the fan-out lines 104 connected to these Data lines need to be bent at a certain angle within the corner area 103 before being led to the pins. Therefore, this part of the fan-out lines 104 occupies a large corner width within the corner area 103, resulting in a relatively large overall width of the lower bezel 102.

[0075] To solve the above problems, in a related technology, such as Figure 2 As shown, Figure 2 This is a schematic diagram of another structure of the display panel in the related technology. A wiring layer 105 can be set in the display area 101. By setting multiple breaks 106 in the wiring layer 105, multiple independent data connection lines 107 can be divided in the wiring layer 105. The data connection lines 107 are connected to the data lines Data near the edge of the display area 101, and the ends of the data connection lines 107 are led out towards the middle position of the lower side of the display area 101. In this way, the fan-out line 104 corresponding to this part of the data line Data can be directly connected to the data connection line 107 at the middle position of the lower side of the display area 101, without having to extend in the corner area 103. This can greatly reduce the width of the corner area 103 and optimize the narrow bezel design of the display panel.

[0076] However, the inventors discovered during the research that, since there is no metal of the wiring layer 105 at the break 106 position of the wiring layer 105, the reflectivity of the location of the break 106 and the location without the break 106 is significantly different from that of the location with the ambient light. This results in a significant difference in the amount of ambient light reflected from different locations, which in turn causes the display panel to easily exhibit a noticeable mura phenomenon when the screen is off.

[0077] Based on this, embodiments of the present invention provide a display panel, such as... Figures 3-6 As shown, Figure 3 This is a schematic diagram of a display panel provided in an embodiment of the present invention. Figure 4 for Figure 3 A corresponding enlarged schematic diagram, Figure 5 This is a schematic diagram of a film layer structure of a display panel provided in an embodiment of the present invention. Figure 6 for Figure 5 A cross-sectional view along the A1-A2 direction shows that the display panel includes a display area 1 and a pad area 2, multiple data lines Data located in the display area 1, and a first wiring layer 3 located in the display area 1.

[0078] The first wiring layer 3 includes multiple data connection lines 4 and multiple trace segments 5, with at least a first break 7 between some of the trace segments 5 and the data connection lines 4. The multiple data connection lines 4 connect to multiple data lines Data, and are used to transmit the data voltage provided by the pins in the pad area 2 to the multiple data lines Data connected to them.

[0079] In one setup method, see Figure 3 The data lines include edge data line Data1 and middle data line Data2. Edge data line Data1 is located on both sides of middle data line Data2, meaning it is closer to the edge of display area 1. Data connection line 4 can connect to edge data line Data1, leading it to the middle area of ​​display area 1. Therefore, when designing the fan-out line corresponding to edge data line Data1, this fan-out line can extend directly from the lower side of the middle area of ​​display area 1 to the pad area 2 and connect to the pins, thus narrowing the corner bezel.

[0080] In addition, the display panel also includes a cover layer 8, which is located on the side of the first wiring layer 3 facing the light-emitting direction of the display panel. The cover layer 8 includes a first cover portion 10 and a second cover portion 9. In a direction perpendicular to the plane of the display panel, the first cover portion 10 overlaps with the first break 7, and the second cover portion 9 overlaps with the data connection line 4 and the wiring segment 5. The thickness of the first cover portion 10 is less than the thickness of at least a portion of the second cover portion 9.

[0081] In this embodiment of the invention, by providing a cover layer 8 on the first wiring layer 3 and designing a differentiated film thickness for the cover layer 8 at different locations, the difference in film thickness of the cover layer 8 can be used to weaken the difference in reflectivity at different locations caused by the first break 7. For example, the first cover portion 10 overlapping with the first break 7 in the cover layer 8 can be made to have a smaller film thickness, thereby reducing the degree of absorption or blocking of ambient light by the first cover portion 10, allowing some ambient light to pass through the first cover portion 10 and be incident on the first break 7, and reflected back through the sidewall of the wiring segment 5 and the sidewall of the data connection line 4, thereby effectively increasing the reflectivity at the location of the first break 7, reducing the difference in reflectivity between the first wiring layer 3 at the first break 7 and where the first break 7 is not provided, and effectively weakening the screen-off mura phenomenon caused by the first break 7.

[0082] It should be noted that, see Figure 5 The display panel includes multiple pixel circuits 60, each comprising a storage capacitor Cst and multiple transistors. Specifically, these transistors may include a driving transistor M0, a gate reset transistor M1, a data writing transistor M2, a threshold compensation transistor M3, an anode reset transistor M4, a first light-emitting control transistor M5, and a second light-emitting control transistor M6. The specific structure and working principle of this pixel circuit 60 will be explained in detail below.

[0083] In one setup method, see Figure 6 The display panel includes a substrate 70, and a semiconductor layer 71, a gate insulating layer 72, a first metal layer 73, a first interlayer dielectric layer 74, a second metal layer 75, a second interlayer dielectric layer 76, a third metal layer 77, and a fourth interlayer dielectric layer 78 sequentially disposed on the substrate 70. The semiconductor layer is used to form at least the active layer of the transistor and the connection line c between the transistors. The first metal layer 73 is used to form at least the gate of the transistor, the first electrode of the storage capacitor Cst, the first scan signal line Scan1, the second scan signal line Scan2, and the light emission control signal line Emit, etc. The second metal layer 75 is used to form at least the second electrode c2 of the storage capacitor Cst and the reset signal line Vref, etc. The third metal layer 77 is used to form at least the first electrode of the transistor, the second electrode of the transistor, the data line Data, and the power signal line PVDD, etc.

[0084] In addition, see Figure 6 At least one first insulating layer 79 may be spaced between the first wiring layer 3 and the cover layer 8.

[0085] In one feasible implementation, such as Figures 7-10 As shown, Figure 7 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Figure 8 for Figure 7 A corresponding enlarged schematic diagram, Figure 9 This is a schematic diagram of another film layer structure of the display panel provided in an embodiment of the present invention. Figure 10 for Figure 9 A cross-sectional view along the B1-B2 direction shows that display area 1 includes a first display area 11 and a second display area 12, with the first display area 11 located on the side of the second display area 12 closer to the pad area 2. Data connection line 4, first break 7, and a portion of the trace segment 5 are located in the first display area 11, while the portion of the trace segment 5 is located in the second display area 12.

[0086] The second cover portion 9 includes a first portion 13 located in the first display area 11. In a direction perpendicular to the plane of the display panel, the first portion 13 overlaps with the data connection line 4 and the wiring segment 5 in the first display area 11. The thickness of the first cover portion 10 is less than the thickness of the first portion 13.

[0087] In the above configuration, the data connection lines 4 are concentrated in the first display area 11, which is closer to the pad area 2. This reduces the extension length of the data connection lines 4, thereby reducing the attenuation difference of the data voltage transmitted on the edge data line Data1 and the middle data line Data2. Due to this configuration, the first break 7 is also concentrated in the first display area 11. Therefore, the first break 7 can cause a localized screen-off mura phenomenon in the first display area 11. To address this, this embodiment of the invention differentiates the film thickness of the first covering portion 10 and the first portion 13 located in the first display area 11 within the cover layer 8. By thinning the first covering portion 10, the reflectivity at the location of the first break 7 can be increased, thereby weakening the reflectivity difference at different locations in the first display area 11 and effectively improving the localized screen-off mura phenomenon within the first display area 11.

[0088] In one feasible implementation, combined with Figures 7-9 ,like Figure 11 and Figure 12 As shown, Figure 11 for Figure 9 A sectional view along the C1-C2 direction. Figure 12 This is a schematic diagram of the film thickness of the cover layer 8 provided in an embodiment of the present invention. The second cover portion 9 also includes a second portion 14 located in the second display area 12. In a direction perpendicular to the plane where the display panel is located, the second portion 14 overlaps with the wiring segment 5 in the second display area 12.

[0089] The second part 14 includes a first sub-part 15 and a second sub-part 16. The thickness of the second sub-part 16 is the same as the thickness of the first part 13, and the thickness of the first sub-part 15 is greater than the thickness of the second sub-part 16.

[0090] Since there is no metal of the first wiring layer 3 at the first break point 7, even after thinning the first covering portion 10 above the first break point 7, the amount of ambient light reflected at the first break point 7 may still be slightly less than the amount of ambient light reflected at other locations. Therefore, this embodiment of the invention further thickens the first sub-part 15 in the second display area 12, making the film thickness of the first sub-part 15 greater than that of the second sub-part 16. This increases the absorption or blocking of ambient light by the first sub-part 15, making the reflectivity of ambient light at the location of the first sub-part 15 less than that at the location of the second sub-part 16. In this way, the degree of reflection of ambient light at the location of the first sub-part 15 can be used to simulate the degree of reflection of ambient light at the location of the first break 7, so that different locations of the second display area 12 also form reflection differences, thereby expanding the mura pattern that originally only existed in the first display area 11 to the entire display area 1. Compared with the local mura pattern, this kind of full-screen mura pattern is not easily visible to the human eye, thus further reducing the risk that the screen-off mura can be recognized by the human eye.

[0091] Furthermore, such as Figure 13 As shown, Figure 13 This is a schematic diagram of the arrangement of the first sub-part 15 and the first break 7 provided in an embodiment of the present invention. The second display area 12 includes at least one sub-area 17, and the sub-area 17 includes a plurality of first sub-parts 15. The patterns of the plurality of first sub-parts 15 in each sub-area 17 after translation correspond one-to-one with the patterns of the plurality of first covering parts 10 in the first display area 11 and overlap with each other.

[0092] In other words, the arrangement of the first sub-parts 15 in each sub-area 17 is consistent with the arrangement of the first break 7 (first covering part 10) in the first display area 11. Therefore, the mura pattern in the first display area 11 and the second display area 12 is periodic, further weakening the contrast of the mura pattern in the two areas, making the full-screen mura less visible to the human eye.

[0093] In one feasible implementation, such as Figure 14 As shown, Figure 14 This is a schematic diagram of the film thickness of the cover layer 8 provided in an embodiment of the present invention. The thickness of the first cover portion 10 is d1, the thickness of the first sub-part 13 is d2, the thickness of the first sub-part 15 is d3, and d2-d1>d3-d2.

[0094] At the first fracture 7, since the reflectivity at the first fracture 7 has been improved to a certain extent by utilizing the thinned first covering portion 10, even if there is still a slight difference in reflectivity between the first fracture 7 and other locations in the first display area 11, the difference will not be too large. Therefore, when designing the first sub-part 15, it is unnecessary to design the first sub-part 15 to be too thick, so that the reflectivity difference formed by the first sub-part 15 and the second sub-part 16 in the second display area 12 can better simulate the reflectivity difference between the first fracture 7 and other locations in the first display area 11, making the mura level in the two areas more consistent.

[0095] In one feasible implementation, such as Figures 15-18 As shown, Figure 15 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Figure 16 for Figure 15 A corresponding enlarged schematic diagram, Figure 17 This is a schematic diagram of a film layer structure of a display panel provided in an embodiment of the present invention. Figure 18 for Figure 17 A cross-sectional view along the D1-D2 direction shows that the trace segment 5 in the second display area 12 has a second break 21. The cover layer 8 also includes a third cover portion 22 located in the second display area 12, which overlaps with the second break 21 in a direction perpendicular to the plane of the display panel. The second cover portion 9 also includes a second portion 14 located in the second display area 12, which overlaps with the trace segment 5 in the second display area 12 in a direction perpendicular to the plane of the display panel, wherein the thickness of the third cover portion 22 is less than the thickness of the second portion 14.

[0096] By setting a second break 21 in the wiring segment 5 of the second display area 12 and thinning the third cover portion 22 in the cover layer 8 corresponding to the second break 21, the effect of the second break 21 and the third cover portion 22 on reflectivity can be used to simulate the effect of the first break 7 and the first cover portion 10 on reflectivity in the first display area 11. This results in different reflection differences at different locations in the second display area 12, thereby expanding the mura pattern that originally only existed in the first display area 11 to the entire display area 1. Compared to a partial mura pattern, this full-screen mura pattern is not easily visible to the human eye, thus reducing the risk of the screen-off mura being recognized by the human eye.

[0097] Furthermore, such as Figure 19 As shown, Figure 19This is another schematic diagram of the film thickness of the cover layer 8 provided in an embodiment of the present invention. The thickness of the first cover portion 10 and the third cover portion 22 are equal, and the thickness of the first portion 13 and the second portion 14 are equal. With this configuration, the degree of reflectivity difference at different positions in the first display area 11 and the degree of reflectivity difference at different positions in the second display area 12 tend to be consistent, and the degree of mura in the two areas tends to be consistent, making this full-screen mura less visible to the human eye.

[0098] Furthermore, such as Figure 20 As shown, Figure 20 This is a schematic diagram of the arrangement of the first break 7 and the second break 21 provided in an embodiment of the present invention. The second display area 12 includes at least one sub-area 17, and the sub-area 17 includes a plurality of second breaks 21. The patterns of the plurality of second breaks 21 in each sub-area 17 after translation correspond one-to-one with the patterns of the plurality of first breaks 7 in the first display area 11 and overlap with each other, so that the mura patterns in the first display area 11 and the second display area 12 are periodic, further weakening the contrast of the mura patterns in the two areas, making this full-screen mura less visible to the human eye.

[0099] In one feasible implementation, such as Figure 21 and Figure 22 As shown, Figure 21 This is a partial structural diagram provided in an embodiment of the present invention. Figure 22 for Figure 21 A cross-sectional view along the E1-E2 direction shows that the first display area 11 includes a first partition 23 and a second partition 24, with the second partition 24 located between the first partition 23 and the second display area 12. The thickness of the first covering portion 10 in the second partition 24 is less than the thickness of the first covering portion 10 in the first partition 23.

[0100] With this configuration, the first covering portion 10 above the first break 7 in the second partition 24 is thinner, resulting in more ambient light being reflected back by the sidewall of this portion of the first break 7. This reduces the difference in reflectivity at different locations in the second partition 24. Consequently, the mura effect is weaker closer to the second display area 12, effectively minimizing the boundary between areas with and without mura.

[0101] In one feasible implementation, such as Figure 23 and Figure 24 As shown, Figure 23 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Figure 24 for Figure 23A cross-sectional view along the F1-F2 direction shows that the display area 1 includes a first display area 11 and a second display area 12. The first display area 11 is located on the side of the second display area 12 close to the pad area 2. The data connection line 4, the first break 7 and a portion of the trace segment 5 are located in the first display area 11, and the portion of the trace segment 5 is located in the second display area 12.

[0102] The second cover portion 9 includes a third portion 25 and a fourth portion 26. The third portion 25 is located in the second display area 12, and in a direction perpendicular to the plane of the display panel, the third portion 25 overlaps with a portion of the wiring segments 5 in the second display area 12. The fourth portion 26 is located in the first display area 11 and the second display area 12, and in a direction perpendicular to the plane of the display panel, the fourth portion 26 overlaps with the data connection lines 4 and wiring segments 5 in the first display area 11, and also overlaps with the remaining wiring segments 5 in the second display area 12. The first cover portion 10 and the fourth portion 26 have the same thickness, while the thickness of the third portion 25 is greater than the thickness of the first cover portion 10.

[0103] In the above configuration, the portion of the cover located in the first display area 11 has a uniform thickness. This configuration increases the film thickness of the third portion 25 in the second display area 12, making it different from the film thickness at other locations. This, in turn, utilizes the third portion 25 to create differences in reflectivity at different locations in the second display area 12, thus allowing the second display area 12 to also exhibit a mura pattern. This expands the mura pattern, which originally only existed in the first display area 11, into a full-screen mura pattern. Compared to partial mura patterns, this full-screen mura pattern is less visible to the human eye, thereby reducing the risk of the mura being recognized by the human eye.

[0104] Furthermore, such as Figure 25 As shown, Figure 25 This is a schematic diagram of the arrangement of the third portion 25 and the first break 7 provided in an embodiment of the present invention. The second display area 12 includes at least one sub-area 17, and the sub-area 17 includes a plurality of third portions 25. The patterns of the plurality of third portions 25 in each sub-area 17 after translation correspond one-to-one with the patterns of the plurality of first covering portions 10 in the first display area 11 and overlap with each other, so that the mura patterns in the first display area 11 and the second display area 12 are periodic, further weakening the contrast of the mura patterns in the two areas, making this full-screen mura less visible to the human eye.

[0105] In one feasible implementation, such as Figure 26 and Figure 27 As shown, Figure 26 This is a schematic diagram of another partial structure of the display panel provided in an embodiment of the present invention. Figure 27 for Figure 26A cross-sectional view along the G1-G2 direction shows that the first wiring layer 3 is in the form of a mesh and has mesh openings. The cover layer 8 also includes a fourth cover portion 27, which overlaps with the mesh openings in a direction perpendicular to the plane of the display panel, and the thickness of the fourth cover portion 27 is equal to the thickness of the first cover portion 10.

[0106] In this embodiment of the invention, the film thickness of the fourth covering portion 27 above the mesh can be further reduced, thereby weakening the reflectivity difference between the first break 7 location and the data connection line 4 and the trace segment location, while further weakening the reflectivity difference between the mesh location and the data connection line 4 and the trace segment location, so as to improve the uniformity of reflection at different locations to a greater extent.

[0107] In one feasible implementation, such as Figure 28 As shown, Figure 28 This is a schematic diagram of another cross-sectional film layer structure of the display panel provided in an embodiment of the present invention. The display panel further includes a light-emitting device layer 28, which is located between the first wiring layer 3 and the cover layer 8. The light-emitting device layer 28 includes an anode 29, a pixel definition layer 30, a light-emitting layer 31, and a cathode 32. The pixel definition layer 30 has an opening, and at least a portion of the light-emitting layer 31 is located within the opening. The light-emitting device layer 28 has a light-emitting area 33 and a non-light-emitting area 34. The light-emitting area 33 corresponds to the opening and is the light-emitting area 33 domain of a sub-pixel in the display panel. The first break 7 is located in the non-light-emitting area 34. Furthermore, in a direction perpendicular to the plane of the display panel, the cover layer 8 overlaps with the non-light-emitting area 34 but does not overlap with the light-emitting area 33, thereby preventing the cover layer 8 from affecting the normal light emission of the light-emitting area 33.

[0108] Moreover, the first break 7 is located in the non-light-emitting area 34, which can prevent the first break 7 from affecting the flatness of the anode 29 in the light-emitting area 33, making the anode 29 film layer relatively flat, thereby improving the consistency of the light emitted by the light-emitting layer 31 in different directions and avoiding color deviation.

[0109] In addition, see Figure 28 A second insulating layer 80 may be provided between the first wiring layer 3 and the light-emitting device layer 28, and a third insulating layer 81 may be provided between the light-emitting device layer 28 and the cover layer 8.

[0110] In one feasible implementation, such as Figure 29 As shown, Figure 29This is a schematic diagram of another cross-sectional film layer structure of the display panel provided in an embodiment of the present invention. The display panel further includes a light filter layer 35, which is located on the side of the first wiring layer 3 facing the light emission direction of the display panel. The light filter layer 35 includes a black matrix 36 and a color resist 37. In one configuration, the light filter layer 35 is located on the side of the light-emitting device layer 28 facing away from the first wiring layer 3. The color resist 37 in the light filter layer 35 is used to filter light of different colors. The light filter layer 35 can replace a polarizer to perform the filtering function.

[0111] In this embodiment of the invention, when the display panel includes a light filter layer 35, the black matrix 36 in the light filter layer 35 can be reused as a cover layer 8. Firstly, the good light-shielding properties of the black matrix 36 are used to reduce the reflection of ambient light at the covered position. Secondly, there is no need to use additional processes to form the cover layer 8, which simplifies the process and reduces the process cost.

[0112] In one feasible implementation, such as Figure 30 As shown, Figure 30 This is a schematic diagram of another cross-sectional film layer structure of the display panel provided in an embodiment of the present invention. The display panel further includes a touch electrode 38, which is located on the side of the first wiring layer 3 facing the light emission direction of the display panel. In this embodiment of the present invention, when the display panel includes the touch electrode 38, at least a portion of the touch electrode 38 can be reused as a cover layer 8, thereby eliminating the need for additional processes to form the cover layer 8, simplifying the process and reducing process costs.

[0113] In one feasible implementation, combined with Figure 6 ,like Figure 31 and Figure 32 As shown, Figure 31 This is another partial structural schematic diagram provided by an embodiment of the present invention. Figure 32 for Figure 31 A cross-sectional view along the H1-H2 direction shows that the display panel includes a first metal layer 73, a second metal layer 75, a third metal layer 77, a fourth metal layer 39, and a fifth metal layer 40 stacked along the light emission direction of the display panel. The functions of the first metal layer 73, the second metal layer 75, and the third metal layer 77 have been described in the above embodiments and will not be repeated here.

[0114] The data line (Data) is located in the third metal layer 77, the portion of the data connection line 4 extending along the first direction (x) is located in the fourth metal layer 39, and the portion of the data connection line 4 extending along the second direction (y) is located in the fifth metal layer 40. The first direction (x) and the second direction (y) intersect. A fourth insulating layer 82 separates the fourth metal layer 39 and the fifth metal layer 40.

[0115] For example, the data line Data extends along the second direction y, and the data connection line 4 includes a first portion 41 extending along the first direction x and a second portion 42 extending along the second direction y. The first portion 41 is located in the fourth metal layer 39, and the second portion 42 is located in the fifth metal layer 40.

[0116] Based on the previous descriptions of the first metal layer 73, the second metal layer 75, and the third metal layer 77, in the above configuration, the data connection line 4 is formed by the fourth metal layer 39 and the fifth metal layer 40. The wiring of the data connection line 4 does not need to affect the original wiring design in the display panel, and therefore does not need to affect the process of the original metal lines.

[0117] In one feasible implementation, combined with Figure 6 ,like Figure 33 and Figure 34 As shown, Figure 33 This is another partial structural schematic diagram provided by an embodiment of the present invention. Figure 34 for Figure 33 A cross-sectional view along the I1-I2 direction shows that the display panel includes a first metal layer 73, a second metal layer 75, a third metal layer 77, and a fifth metal layer 40 stacked along the light emission direction of the display panel. The data line 'Data' is located on the third metal layer 77, and the data connection line '4' is located on the fifth metal layer 40.

[0118] Based on the previous descriptions of the first metal layer 73, the second metal layer 75, and the third metal layer 77, in the above configuration, the data connection line 4 is formed using the fifth metal layer 40. The wiring of the data connection line 4 does not need to affect the original wiring design in the display panel, and therefore does not need to affect the process of the original metal lines. Moreover, the first part 41 and the second part 42 in the data connection line 4 are set on the same layer, and the first part 41 and the second part 42 have the same degree of reflection of ambient light.

[0119] In one feasible implementation, combined with Figure 6 ,like Figure 35 and Figure 36 As shown, Figure 35 This is another partial structural schematic diagram provided by an embodiment of the present invention. Figure 36 for Figure 35 A cross-sectional view along the J1-J2 direction shows that the display panel includes a first metal layer 73, a second metal layer 75, a third metal layer 77, and a fourth metal layer 39 stacked along the light emission direction of the display panel. The data line Data is located in the third metal layer 77, the portion of the data connection line 4 extending in the same direction as the data line Data is located in the third metal layer, and the portion of the data connection line 4 extending intersecting with the data line Data is located in the fourth metal layer 39.

[0120] In the above configuration, although the data cable 4 adopts a double-layer wiring design, one layer can be formed using the same patterning process as the data cable (Data), simplifying the manufacturing process. Furthermore, the portion of the data cable 4 that is on the same layer as the data cable (Data) extends in the same direction as the data cable (Data), thus avoiding short circuits between the two.

[0121] In one feasible implementation, see Figure 31 , Figure 33 and Figure 35 The data connection line 4 includes a first portion 41 extending along a first direction x and a second portion 42 extending along a second direction y. The trace segment 5 includes a first type of trace segment 43 extending along the first direction x and a second type of trace segment 44 extending along the second direction y. The first direction x and the second direction y intersect. The first type of trace segment 43 is disposed on the same layer as the first portion 41, and a portion of the first type of trace segment 43 is aligned with the first portion 41 in the first direction x. The second type of trace segment 44 is disposed on the same layer as the second portion 42, and a portion of the second type of trace segment 44 is aligned with the second portion 42 in the second direction y. In this configuration, the trace segment 5 and the data connection line 4 are arranged in a relatively regular manner. Furthermore, the trace segment 5 can be formed together with the data connection line 4 without requiring additional processes or additional film thickness.

[0122] In one feasible implementation, such as Figure 37 As shown, Figure 37 This is a schematic diagram of a structure of the first break 7 provided in an embodiment of the present invention. In a direction perpendicular to the plane where the display panel is located, at least one edge of the first break 7 has an angle A with the extension direction of the data line Data, where 0° < A < 90°.

[0123] With this configuration, the edge of the first break 7 is relatively inclined, for example, A = 45°. In this way, the transmission angle of the light reflected by the sidewall of the first break 7 via the data connection line 4 or the trace segment 5 observed at different azimuth angles is inconsistent, which can further weaken the visibility of the first break 7.

[0124] In one feasible implementation, see again Figure 37The data connection line 4 includes a first portion 41 extending along a first direction x and a second portion 42 extending along a second direction y. The first break 7 includes a first type of first break 45 located between the first portion 41 and the trace segment 5 and a second type of first break 46 located between the second portion 42 and the trace segment 5. Specifically, in a direction perpendicular to the plane of the display panel, the extension direction of at least one edge of the first type of first break 45 is different from the extension direction of at least one edge of the second type of first break 46. This results in different amounts of ambient light reflected to the human eye from the edges of different first breaks 7 at the same azimuth angle, further reducing the visibility of the first break 7.

[0125] This invention also provides a display panel, such as... Figures 38-42 As shown, Figure 38 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Figure 39 for Figure 38 A corresponding enlarged schematic diagram, Figure 40 This is a schematic diagram of another film layer structure of the display panel provided in an embodiment of the present invention. Figure 41 for Figure 40 A cross-sectional view along the L1-L2 direction. Figure 42 for Figure 40 A cross-sectional view along the M1-M2 direction shows that the display panel includes a display area 1 and a pad area 2, wherein the display area 1 includes a first display area 11 and a second display area 12, and the first display area 11 is located on the side of the second display area 12 close to the pad area 2.

[0126] The display panel also includes multiple data lines (Data) located in the display area 1 and a first wiring layer 3 located in the display area 1. The first wiring layer 3 includes multiple data connection lines 4 and multiple trace segments 5. The multiple data connection lines 4 are located in the first display area 11 and connect to the multiple data lines (Data) for transmitting the data voltage provided by the pad area 2 to the multiple data lines (Data) connected to it. The trace segments 5 are located in the first display area 11 and the second display area 12, and at least a portion of the trace segments 5 are separated from the data connection lines 4 by a first break 7.

[0127] The display panel also includes a cover layer 8, which is located on the side of the first wiring layer 3 facing the light-emitting direction of the display panel. The cover layer 8 includes a fifth cover portion 50 and a sixth cover portion 51. The fifth cover portion 50 is located in the second display area 12, and in a direction perpendicular to the plane of the display panel, the fifth cover portion 50 overlaps with a portion of the wiring segments 5 in the second display area 12. The sixth cover portion 51 is located in the first display area 11 and the second display area 12, and in a direction perpendicular to the plane of the display panel, the sixth cover portion 51 overlaps with the first break 7, the data connection line 4, and the wiring segments 5 in the first display area 11. The sixth cover portion 51 also overlaps with the remaining wiring segments 5 in the second display area 12. The thickness of the fifth cover portion 50 is greater than the thickness of the sixth cover portion 51.

[0128] In this embodiment of the invention, by providing a cover layer 8 on the first wiring layer 3 and designing differentiated film thicknesses for the cover layer 8 at different locations, the risk of the mura phenomenon caused by the first break 7 being visible to the human eye can be reduced by utilizing the difference in film thickness of the cover layer 8. Specifically, by increasing the film thickness of the fifth cover portion 50 in the second display area 12, the difference in film thickness between the fifth cover portion 50 and the sixth cover portion 51 in the second display area 12 can be used to create a difference in reflectivity at different locations, so that the second display area 12 also has a mura pattern. In this way, the mura pattern that originally existed only in the first display area 11 caused by the first break 7 can be expanded into a full-screen mura pattern. Compared to a partial mura pattern, this full-screen mura pattern is less likely to be visible to the human eye, thus reducing the risk of the mura being recognized by the human eye.

[0129] Furthermore, such as Figure 43 As shown, Figure 43 This is a schematic diagram of the arrangement of the fifth covering portion 50 and the first break 7 provided in an embodiment of the present invention. The second display area 12 includes at least one sub-area 17, and the sub-area 17 includes a plurality of fifth covering portions 50. The patterns of the plurality of fifth covering portions 50 in each sub-area 17 after translation correspond one-to-one with the patterns of the plurality of first break 7 in the first display area 11 and overlap with each other, thereby making the mura patterns in the first display area 11 and the second display area 12 periodic, further weakening the contrast of the mura patterns in the two areas, making this full-screen mura less visible to the human eye.

[0130] In one feasible implementation, see again Figure 28The display panel also includes a light-emitting device layer 28, located between the first wiring layer 3 and the cover layer 8. The light-emitting device layer 28 has a light-emitting area 33 and a non-light-emitting area 34. The light-emitting device layer 28 includes an anode 29, a pixel definition layer 30, a light-emitting layer 31, and a cathode 32. The pixel definition layer 30 has an opening, and at least a portion of the light-emitting layer 31 is located within the opening. The light-emitting device layer 28 has a light-emitting area 33 and a non-light-emitting area 34. The light-emitting area 33 corresponds to the opening and is the light-emitting area 33 domain of a sub-pixel in the display panel. The first break 7 is located in the non-light-emitting area 34. Furthermore, in a direction perpendicular to the plane of the display panel, the cover layer 8 overlaps with the non-light-emitting area 34 but does not overlap with the light-emitting area 33, thereby preventing the cover layer 8 from affecting the normal light emission of the light-emitting area 33.

[0131] Moreover, the first break 7 is located in the non-light-emitting area 34, which can prevent the first break 7 from affecting the flatness of the anode 29 in the light-emitting area 33, making the anode 29 film layer relatively flat, thereby improving the consistency of the light emitted by the light-emitting layer 31 in different directions and avoiding color deviation.

[0132] In one feasible implementation, see again Figure 29 The display panel also includes a light filter layer 35, which is located on one side of the first wiring layer 3 in the light-emitting direction of the display panel. The light filter layer 35 includes a black matrix 36 and a color resist 37. In one configuration, the light filter layer 35 is located on the side of the light-emitting device layer 28 facing away from the first wiring layer 3. The color resist 37 in the light filter layer 35 is used to filter light of different colors. The light filter layer 35 can replace a polarizer to perform the filtering function.

[0133] In this embodiment of the invention, when the display panel includes a light filter layer 35, the black matrix 36 in the light filter layer 35 can be reused as a cover layer 8. Firstly, the good light-shielding properties of the black matrix 36 are used to reduce the reflection of ambient light at the covered position. Secondly, there is no need to use additional processes to form the cover layer 8, which simplifies the process and reduces the process cost.

[0134] In one feasible implementation, see again Figure 30 The display panel also includes touch electrodes 38, which are located on the side of the first wiring layer 3 facing the light-emitting direction of the display panel. In this embodiment of the invention, when the display panel includes touch electrodes 38, at least a portion of the touch electrodes 38 can be reused as a cover layer 8, thereby eliminating the need for additional processes to form the cover layer 8, simplifying the process and reducing process costs.

[0135] In one feasible implementation, see Figure 6 , Figure 31 and Figure 32The display panel includes a first metal layer 73, a second metal layer 75, a third metal layer 77, a fourth metal layer 39, and a fifth metal layer 40 stacked along the light emission direction of the display panel. The data line 'Data' is located on the third metal layer 77, the portion of the data connection line 4 extending along the first direction x is located on the fourth metal layer 39, and the portion of the data connection line 4 extending along the second direction y is located on the fifth metal layer 40. The first direction x and the second direction y intersect.

[0136] For example, the data line Data extends along the second direction y, and the data connection line 4 includes a first portion 41 extending along the first direction x and a second portion 42 extending along the second direction y. The first portion 41 is located in the fourth metal layer 39, and the second portion 42 is located in the fifth metal layer 40.

[0137] Based on the previous descriptions of the first metal layer 73, the second metal layer 75, and the third metal layer 77, in the above configuration, the data connection line 4 is formed by the fourth metal layer 39 and the fifth metal layer 40. The wiring of the data connection line 4 does not need to affect the original wiring design in the display panel, and therefore does not need to affect the process of the original metal lines.

[0138] In one feasible implementation, see Figure 6 , Figure 33 and Figure 34 The display panel includes a first metal layer 73, a second metal layer 75, a third metal layer 77, and a fifth metal layer 40 stacked along the light emission direction of the display panel. The data line (Data) is located on the third metal layer 77, and the data connection line (4) is located on the fifth metal layer 40.

[0139] Based on the previous descriptions of the first metal layer 73, the second metal layer 75, and the third metal layer 77, in the above configuration, the data connection line 4 is formed using the fifth metal layer 40. The wiring of the data connection line 4 does not need to affect the original wiring design in the display panel, and therefore does not need to affect the process of the original metal lines. Moreover, the first part 41 and the second part 42 in the data connection line 4 are set on the same layer, and the first part 41 and the second part 42 have the same degree of reflection of ambient light.

[0140] In one feasible implementation, see Figure 6 , Figure 35 and Figure 36 The display panel includes a first metal layer 73, a second metal layer 75, a third metal layer 77, and a fourth metal layer 39 stacked along the light emission direction of the display panel. The data line Data is located on the third metal layer 77, the portion of the data connection line 4 extending in the same direction as the data line Data is located on the third metal layer, and the portion of the data connection line 4 extending intersecting with the data line Data is located on the fourth metal layer 39.

[0141] In the above configuration, although the data cable 4 adopts a double-layer wiring design, one layer can be formed using the same patterning process as the data cable (Data), simplifying the manufacturing process. Furthermore, the portion of the data cable 4 that is on the same layer as the data cable (Data) extends in the same direction as the data cable (Data), thus avoiding short circuits between the two.

[0142] In one feasible implementation, see Figure 31 , Figure 33 and Figure 35 The data connection line 4 includes a first portion 41 extending along a first direction x and a second portion 42 extending along a second direction y. The trace segment 5 includes a first type of trace segment 43 extending along the first direction x and a second type of trace segment 44 extending along the second direction y. The first direction x and the second direction y intersect. The first type of trace segment 43 is disposed on the same layer as the first portion 41, and a portion of the first type of trace segment 43 is aligned with the first portion 41 in the first direction x. The second type of trace segment 44 is disposed on the same layer as the second portion 42, and a portion of the second type of trace segment 44 is aligned with the second portion 42 in the second direction y. In this configuration, the trace segment 5 and the data connection line 4 are arranged in a relatively regular manner. Furthermore, the trace segment 5 can be formed together with the data connection line 4 without requiring additional processes or additional film thickness.

[0143] In one feasible implementation, see Figure 37 In a direction perpendicular to the plane of the display panel, at least one edge of the first break 7 has an angle A with the extension direction of the data line Data, where 0° < A < 90°.

[0144] With this configuration, the edge of the first break 7 is relatively inclined, for example, A = 45°. In this way, the transmission angle of the light reflected by the sidewall of the first break 7 via the data connection line 4 or the trace segment 5 observed at different azimuth angles is inconsistent, which can further weaken the visibility of the first break 7.

[0145] In one feasible implementation, see Figure 37 The data connection line 4 includes a first portion 41 extending along a first direction x and a second portion 42 extending along a second direction y. The first break 7 includes a first type of first break 45 located between the first portion 41 and the trace segment 5 and a second type of first break 46 located between the second portion 42 and the trace segment 5. Specifically, in a direction perpendicular to the plane of the display panel, the extension direction of at least one edge of the first type of first break 45 is different from the extension direction of at least one edge of the second type of first break 46. This results in different amounts of ambient light reflected to the human eye from the edges of different first breaks 7 at the same azimuth angle, further reducing the visibility of the first break 7.

[0146] Furthermore, it should be noted that in the structure of the display panel mentioned above, combined with Figure 5 and Figure 40 In one configuration method, such as Figure 44 As shown, Figure 44 This is a schematic diagram of a pixel circuit 60 provided in an embodiment of the present invention. The pixel circuit 60 may specifically include a driving transistor M0, a gate reset transistor M1, an anode reset transistor M4, a data writing transistor M2, a threshold compensation transistor M3, a first light-emitting control transistor M5, a second light-emitting control transistor M6, and a storage capacitor Cst.

[0147] In this configuration, the gate of the gate reset transistor M1 is electrically connected to the first scan signal line Scan1, the first terminal of the gate reset transistor M1 is electrically connected to the reset signal line Vref, and the second terminal of the gate reset transistor M1 is electrically connected to the gate of the driving transistor M0. The first sub-reset transistor M11 is used to perform a reset operation on the gate of the driving transistor M0 when it is turned on.

[0148] The gate of the anode reset transistor M4 is electrically connected to the second scan signal line Scan2, the first terminal of the anode reset transistor M4 is electrically connected to the reset signal line Vref, and the second terminal of the anode reset transistor M4 is electrically connected to the anode of the light-emitting element 61. The anode reset transistor M4 is used to perform a reset operation on the anode of the light-emitting element 61 when it is turned on.

[0149] The gates of data writing transistor M2 and threshold compensation transistor M3 are electrically connected to the second scan signal line Scan2. The first terminal of data writing transistor M2 is electrically connected to the data line Data, and the second terminal of data writing transistor M2 is electrically connected to the first terminal of driving transistor M0. The first terminal of threshold compensation transistor M3 is electrically connected to the second terminal of driving transistor M0, and the second terminal of threshold compensation transistor M3 is electrically connected to the gate of driving transistor M0. Data writing transistor M2 and threshold compensation transistor M3 are used to charge the gate of driving transistor M0 and perform threshold compensation when it is turned on.

[0150] The gates of the first light-emitting control transistor M5 and the second light-emitting control transistor M6 are electrically connected to the light-emitting control signal line Emit, respectively. The first terminal of the first light-emitting control transistor M5 is electrically connected to the power signal line PVDD, and the second terminal of the first light-emitting control transistor M5 is electrically connected to the first terminal of the driving transistor M0. The first terminal of the second light-emitting control transistor M6 is electrically connected to the second terminal of the driving transistor M0, and the second terminal of the second light-emitting control transistor M6 is electrically connected to the anode of the light-emitting element 61. The first light-emitting control transistor M5 and the second light-emitting control transistor M6 are used to transmit the driving current converted by the driving transistor M0 to the light-emitting element 61 when they are turned on, thereby driving the light-emitting element 61 to emit light.

[0151] It should be noted that for two adjacent rows of pixel circuits 60, the second scan signal line corresponding to the previous row of pixel circuits 60 can be multiplexed as the first scan signal line corresponding to the next row of pixel circuits 60. See [link / reference] Figure 5 The first scan signal line electrically connected to the anode reset transistor M4 can be regarded as either the second scan signal line corresponding to the pixel circuit 60 in the current row or the first scan signal line corresponding to the pixel circuit 60 in the next row.
