Description

Display panel and display device Technical Field

[0001] Embodiments of the present disclosure relate to a display panel and a display device. Background Art

[0002] A display panel typically consists of a display area and a non-display area. The display area is used to display the desired image, while the non-display area is used to house the circuit structure that controls the operation of the display area. The circuit structure includes, for example, a display driver circuit, various traces, and a flexible circuit board. The non-display area may also be equipped with various structures to ensure screen encapsulation, such as a dam.

[0057] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. The embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0058] Unless otherwise defined, the technical or scientific terms used herein should have the usual meanings understood by persons of ordinary skill in the field to which the invention belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0059] Due to the existence of various wirings of the display panel, after the light is reflected and refracted between the film layers in the non-display area, when the display panel is in the off state, the user can still see the light reflected from the non-display area, thereby forming a light leakage phenomenon. In order to prevent light leakage in the non-display area of ​​the display panel, for example, a light-shielding layer can be coated on the non-display area to block the light. However, the light-shielding layer has problems such as fitting tolerance and manufacturing tolerance. At the same time, in order to meet the needs of the entire machine, the edge of the light-shielding layer is a certain distance away from the display area. Since there is a light leakage area between the edge of the light-shielding layer close to the display area and the display area that is not blocked by the light-shielding layer, the light in the light leakage area will not be blocked, so that light can penetrate from the light leakage area.

Those skilled in the art can design the light-shielding structures based on the size of the light leakage area. The dimensions of the various structures in the figures do not represent actual dimensions; all figures are schematic diagrams.

[0064] For example, for example, FIG1 is a schematic diagram of a display panel provided by an embodiment of the present disclosure, FIG3 is a schematic diagram after removing the shading structure in the local P1 of the display panel shown in FIG1, and FIG4 is a schematic diagram of the local P1 including the shading structure in the portion near the first edge of the non-display area shown in FIG1. ​​Referring to FIG1, FIG3 and FIG4, the display panel 10 provided by at least one embodiment of the present disclosure includes: a substrate 1, a touch signal line TL and a shading structure 3. The substrate 1 includes a display area 101 and a non-display area 102 that at least partially surrounds the display area 101, the display area 101 includes display pixels, the substrate 1 has a main surface, and the display pixels, the touch signal line TL, the shading structure 3 and the following multiple dam glues are located on the main surface of the substrate 1. The touch signal line TL is located in the non-display area 102, at least partially surrounds the display area 101, and is configured to provide a touch signal to the display area 101; the shading structure 3 is located in the non-display area 102, at least partially surrounds the display area 101, and is located on the side of the touch signal line TL away from the display area 101, the shading structure 3 includes a first shading structure 011 / 021 and a second shading structure 012 / 022, the first shading structure 011 / 021 and the second shading structure 012 / 022 are respectively located in different layers, and the orthographic projections of the first shading structure 011 / 021 and the second shading structure 012 / 022 adjacent to each other in the direction from the display area 101 to the non-display area 102 on the substrate 1 do not completely overlap. A variety of wirings are provided in the non-display area 102 near the display area 101, such as a plurality of touch signal lines TL, a ground line GND, etc. However, the plurality of touch signal lines TL are arranged at intervals, and there are also some gaps between the touch signal lines TL and other wirings such as the ground line GND. Therefore, due to the fitting tolerance and manufacturing tolerance of the light shielding layer in the non-display area 102, as well as the intervals between the various wirings, the light shielding layer and the various wirings in the non-display area 102 cannot completely cover the non-display area 102, which results in the non-display area 102 still having a light leakage area where light leakage occurs in the uncovered area, thereby causing light leakage in the non-display area, for example, light leakage at the edge of the screen near the display area. The embodiment of the present disclosure improves the light leakage phenomenon at the edge of the display screen of the display panel by shielding the light shielding structure 3, that is, shielding the light leakage area. The first shading structure and the second shading structure located in different layers can overlap with each other, thereby increasing the shielding area of ​​the light leakage area. For example, the overlapping first shading structure and the second shading structure can completely block the light leakage area, achieving a better shading effect in the non-display area 102.

[0065] Different layers refer to at least two different film layers arranged in a direction perpendicular to the main surface of the substrate 1 , and the at least two film layers need to be obtained by performing different patterning processes on different film layers.

[0066] Reference numerals 011 and 021 respectively denote a first light shielding structure and a second light shielding structure in the first light leakage region R1 , and reference numerals 021 and 022 respectively denote a first light shielding structure and a second light shielding structure in the second light leakage region R2 , which will be described in detail below.

[0067] For example, the width of the overlapping parts of the orthographic projections of the first shading structure 011 / 021 and the second shading structure 012 / 022 adjacent to each other in the direction from the display area 101 to the non-display area 102 on the substrate in the direction from the display area 101 to the non-display area 102 is greater than 1 μm, so as to meet the requirements of the manufacturing process while ensuring a good shading effect, and to produce products that meet the requirements and ensure the yield of the display panel.

[0068] FIG2 is a schematic diagram of a touch structure 40 of a display panel 10 provided in an embodiment of the present disclosure. As shown in FIG2 , for example, the touch electrode structure 40 is located in the display area 101 and includes first and second touch electrodes. The first touch electrodes include a plurality of first touch electrode channels 410 spaced apart from each other (a first touch electrode channel 410 is indicated by a corresponding dotted line in FIG2 ), and the second touch electrodes include a plurality of second touch electrode channels 420 spaced apart from each other (a second touch electrode channel 420 is indicated by a corresponding dotted line in FIG2 ). The plurality of second touch electrode channels 420 extend in a direction that intersects with the plurality of first touch electrode channels 410. For example, the plurality of first touch electrode channels 410 extend along a first direction D1, and the plurality of second touch electrode channels 420 extend along a second direction D2. The second direction D2 intersects with the first direction D1, for example, the second direction D2 is perpendicular to the first direction D1. This facilitates electrical connection with the plurality of touch signal lines TL and ensures a regular pattern. Of course, the extension direction of the plurality of second touch electrode channels 420 and the extension direction of the plurality of first touch electrode channels 410 are not limited to this case. For example, the first touch electrode channels 410 may be touch sensing electrodes Rx, and the second touch electrode channels 420 may be touch drive electrodes Tx. However, the present disclosure is not limited to this. In other examples, the first touch electrode channels 410 may be touch drive electrodes Tx, and the second touch electrode channels 420 may be touch sensing electrodes Rx.

[0069] Each first touch electrode channel 410 includes a plurality of first sub-touch electrodes 411 spaced apart from each other, and each second touch electrode channel 420 includes a plurality of second sub-touch electrodes 421 sequentially arranged and connected to each other along the second direction D2. For example, the plurality of second sub-touch electrodes 421 are disposed on the same layer as the plurality of first sub-touch electrodes 411 and are insulated from each other. The touch structure further includes a bridge electrode 412, which is disposed on a different layer from the plurality of second sub-touch electrodes 421 and the plurality of first sub-touch electrodes 411. The bridge electrode 412 electrically connects two adjacent first sub-touch electrodes 411 in the plurality of first sub-touch electrodes 411 of the same first touch electrode channel 410 and is insulated from the second touch electrode channel 420. That is, adjacent first sub-touch electrodes 411 in the first direction D1 are electrically connected via the bridge electrode 412 to form the first touch electrode channel 410, and adjacent second sub-touch electrodes 421 in the second direction D2 are electrically connected via a second connecting electrode (not shown) to form the second touch electrode channel 420. For example, the touch structure 40 includes a first metal layer and a second metal layer. The second touch electrode channels 420 and the first touch electrode channels 410 are located in the first metal layer of the touch structure 40 . The bridge electrodes 412 are located in the second metal layer of the touch structure 40 .

[0070] The embodiment of the present disclosure does not limit the shape of the main outline of each of the first sub-touch electrode 411 and the second sub-touch electrode 421. For example, they can both be diamond-shaped as shown in FIG2. In other examples, the first sub-touch electrode 411 and the second sub-touch electrode 421 can also be other shapes, such as rectangular, triangular, etc.

[0071] Each first touch electrode channel 410 and each second touch electrode channel 420 are insulated from each other and cross each other to form a plurality of touch units 400 at the intersection. Each touch unit includes a portion of each of the two first touch electrode portions connected at the intersection and at least a portion of each of the two second touch electrode portions connected at the intersection. An enlarged schematic diagram of a touch unit 400 is shown on the right side of Figure 2. As shown in Figure 2, each touch unit 400 includes half of each area of ​​two adjacent first sub-touch electrodes 411 and half of each area of ​​two adjacent second sub-touch electrodes 421, that is, an area including one first sub-touch electrode 411 and one second sub-touch electrode 421 on average. The intersection point of the first sub-touch electrode 411 and the second sub-touch electrode 421 in each touch unit 400 (that is, the intersection of the bridge electrode and the second connecting electrode) forms a reference point for calculating coordinates. When a finger touches the capacitive screen, it affects the coupling between the first touch electrode and the second touch electrode near the touch point, thereby changing the mutual capacitance between the two electrodes. The touch sensing signal changes according to the change in capacitance of the touch screen, so that the coordinates of each touch point can be calculated based on the reference point.

[0072] For example, multiple touch signal lines TL are connected to multiple touch drive electrodes in a one-to-one correspondence and are configured to provide touch signals to the corresponding touch drive electrodes. For example, when the first touch electrode channels 410 are touch drive electrodes Tx, the multiple touch signal lines TL are connected to the multiple first touch electrode channels 410 in a one-to-one correspondence and are configured to provide touch signals to the corresponding first touch electrode channels 410. Of course, in other embodiments, when the second touch electrode channels 420 are touch drive electrodes Tx, the multiple touch signal lines TL are connected to the multiple second touch electrode channels 420 in a one-to-one correspondence and are configured to provide touch signals to the corresponding second touch electrode channels 420.

[0073] For example, in the disclosed embodiment, the first light-shielding structures 011 / 021 can be made of the same material and layer as the touch signal lines TL; alternatively, the second light-shielding structures 012 / 021 can be made of the same material and layer as the touch signal lines TL. Of course, the specific film layers where the first and second light-shielding structures are located are not limited to the above, as long as they can block the light leakage area.

[0074] For example, one of the first light-shielding structure 011 / 021 and the second light-shielding structure 012 / 021 is made of the same material and disposed on the same layer as the first sub-touch electrode 411 and the second sub-touch electrode 421, and the other of the first light-shielding structure 011 / 021 and the touch signal line TL is made of the same material and disposed on the same layer as the bridge electrode 412. For example, the touch signal line TL is also made of the same material and disposed on the same layer as one of the first light-shielding structure 011 / 021 and the second light-shielding structure 012 / 021; alternatively, the touch signal line TL is also made of the same material and disposed on the same layer as the other of the first light-shielding structure 011 / 021 and the second light-shielding structure 012 / 021 and the bridge electrode.

[0075] FIG5 is a schematic cross-sectional view of a non-display area of ​​a display panel including a light-shielding structure provided by an embodiment of the present disclosure. Referring to FIG4 and FIG5 , the display panel 10 further includes a light-shielding layer 2, the light-shielding layer 2 being located in the non-display area 102 and at least partially surrounding the display area 101, the touch signal line TL being located on a side of the light-shielding layer 2 close to the display area 101, and the light-shielding structure 3 being located between the light-shielding layer 2 and the touch signal line TL to shield a light leakage area between an edge of the light-shielding layer 2 close to the display area 101 and an edge of the touch signal line TL away from the display area 101; for example, the light-shielding structure 3 extends beyond the edge of the light-shielding layer 2, that is, the orthographic projection of at least a portion of the light-shielding structure 3 on the substrate 1 overlaps with the orthographic projection of the edge of the light-shielding layer 2 close to the display area 101 on the substrate 1, to ensure that no light leakage area exists as much as possible even after the light-shielding layer 2 has a lamination deviation, thereby achieving a better effect of preventing light leakage from the edge of the display panel. Of course, in some embodiments, the orthographic projection of the light-shielding structure 3 on the substrate 1 may not overlap with the orthographic projection of the edge of the light-shielding layer 2 close to the display area 101 on the substrate 1 , which can also achieve the effect of shielding the light leakage area.

[0076] For example, the material of the light-shielding layer 2 is a light-proof material, such as a light-proof organic material, for example, a light-proof ink, such as black ink, so as to achieve a relatively ideal light-shielding effect and be easy to manufacture. In other embodiments, the material of the light-shielding layer 2 may also be other types of light-proof materials, including light-proof inks of other colors, etc. The type of the light-shielding layer 2 is not limited to black ink. The embodiment of the present disclosure does not limit the type of the light-shielding layer 2, as long as it is light-proof and can block light leakage from the non-display area due to refraction and reflection, and prevent the leakage from being emitted from the display side of the display panel 10 in the non-display area 102.

[0077] For example, the touch signal line TL includes a first portion extending along a first direction D1. The arrangement direction of the touch signal line TL and the light shielding structure 3 is a second direction D2. The first direction D1 and the second direction D2 intersect, for example, the first direction D1 is perpendicular to the second direction D2. For example, the second direction D2 is a direction from the display area to the non-display area or from the non-display area to the display area. For example, referring to Figures 4 and 5, the display panel 10 includes a main ground line GND. The main ground line GND is located on a side of the touch signal line TL away from the display area 101 to prevent the touch signal line TL from being interfered with by interference signals. The main ground line GND includes a first portion GND1 surrounding the display area 101 and extending along the first direction D1. That is, the first portion GND1 of the main ground line GND and the first portion of the touch signal line TL both extend along the first direction D1.

[0078] For example, the main ground line GND and the touch signal line TL, and one of the first light shielding structure 011 / 021 and the second light shielding structure 012 / 022 are disposed on the same layer, for example, these structures disposed on the same layer are made of the same material.

[0079] For example, in the embodiment of the present disclosure, the first shading structure 011 / 021 and the second shading structure 012 / 022 have the same extension direction as the touch signal line TL and are substantially parallel. This is not limited to being absolutely parallel. For example, deviations within 5° from each other can be considered substantially parallel.

[0080] For example, the line width of at least one first light-shielding structure 011 / 021 in the direction from the display area 101 to the non-display area 102 is equal to the line width of the first portion GND1 of the main ground line GND in the direction from the display area 101 to the non-display area 102, and the line width of at least one second light-shielding structure 012 / 022 in the direction from the display area 101 to the non-display area 102 is equal to the line width of the first portion GND1 of the main ground line GND in the direction from the display area 101 to the non-display area 102. For example, the plurality of first light-shielding structures 011 / 021 and the first portion GND1 of the main ground line GND are arranged at equal intervals, and the plurality of second light-shielding structures 012 / 022 and the first portion GND1 of the main ground line GND are arranged at equal intervals. Usually, patterns of various wires and electrodes such as the touch electrode line TL, the main ground line GND, the first shading structure 011 / 021 and the second shading structure 012 / 022 are formed through a composition process including an etching step. In this way, the multiple first shading structures 011 / 021, the multiple second shading structures 012 / 022 and the first part GND1 of the main ground line GND can have better etching uniformity, and the shielding of the first light leakage area 103a is also more stringent, thereby achieving a better effect of preventing light leakage from the edge of the display panel.

[0081] For example, as shown in Figure 1, the substrate 1 also includes a bendable portion 104 located at the edge of the non-display area 102 away from the display area 101, and an extension portion 105 connected to the bendable portion 104; the display panel 10 has a first side for display and a second side opposite to the first side, the extension portion 105 is connected to the bendable portion 104 and can be bent to the second side of the display panel 10 through the bendable portion 104; the integrated circuit board 4 is located at the extension portion 105.

[0082] For example, as shown in FIG1 , the display panel 10 has a first edge 11, a second edge 12 intersecting the first edge 11, a third edge 13 opposite the first edge 11, and a fourth edge 14 opposite the second edge 12, and the extension 105 is provided along the first edge 11 of the display panel 10. At least one shielding line extends along at least a portion of the first edge 11, or at least one shielding line extends along at least a portion of the first edge 11 and along at least one of the second edge 12, the third edge 13, and the fourth edge 14.

[0083] Referring to the schematic diagram of the non-display area near first edge 11 after removing the shielding structures 3, shown in FIG3 , the non-display area 102 near first edge 11 of the integrated circuit board 4 has a relatively large light leakage area, particularly the first light leakage area R1 between the light shielding layer 2 and the main ground line GND. Therefore, sufficient light shielding structures 3 need to be provided in the first light leakage area R1 near first edge 11. For example, light shielding structures 3 may also be provided along at least one of other edges, such as the second edge 12, the third edge 13, and the fourth edge 14. For example, the number of light shielding structures 3 provided at the first edge 11 is greater than that provided at other edges.

[0084] For example, referring to Figures 3-4, the light leakage area of ​​the non-display area 102 of the display panel 10 includes the aforementioned first light leakage area R1, which is located between the edge of the light shielding layer 2 near the display area 101 and the ground line GND. For example, the first light leakage area R1 is located between the edge of the light shielding layer 2 near the display area 101 and the edge of the ground line GND away from the display area 101. At least a portion of the first light shielding structure 011 and at least a portion of the second light shielding structure 012 are located on the side of the first portion GND1 of the main ground line GND away from the display area 101, that is, located in the first light leakage area R1. For example, the light shielding structure 3 includes a first partial light shielding structure 01 disposed in the first light leakage area R1, and the first partial light shielding structure 01 includes a first light shielding structure 011 located in the first light shielding layer M1 and a second light shielding structure 012 located in the second light shielding layer M2.

[0085] For example, the materials of the first light shielding layer M1 and the second light shielding layer M2 are both opaque metal materials, such as at least one of copper, aluminum, chromium, manganese, and copper alloys thereof. Of course, the materials of the first light shielding layer M1 and the second light shielding layer M2 in the embodiment of the present disclosure are not limited.

[0086] For example, the shading structure 3 includes multiple first shading structures 011 and multiple second shading structures 012. The multiple first shading structures 011 are arranged along the direction from the display area 101 to the non-display area 102, and the multiple second shading structures 012 are arranged along the direction from the display area 101 to the non-display area 102. There are gaps between the multiple first shading structures 011, and there are gaps between the multiple second shading structures 012.

[0087] Figure 5 illustrates a first partial light-shielding structure 01 disposed in the first light-leakage region R1. In conjunction with Figures 4 and 5, for example, multiple first light-shielding structures 011 are located in the first light-shielding layer M1, and second light-shielding structures 012 are located in the second light-shielding layer M2. For example, the orthographic projections of adjacent first light-shielding structures 011 and second light-shielding structures 012 on substrate 1 partially overlap in the direction from the display area 101 to the non-display area 102. As can be seen in Figure 5, the orthographic projections of multiple first light-shielding structures 011 and multiple second light-shielding structures 012 on substrate 1 overlap. For example, referring to Figure 5, the orthographic projection of the second light-shielding structure 012 on the substrate 1 at least partially overlaps with the orthographic projection of the intervals between the multiple first light-shielding structures 011 on the substrate 1; or, the orthographic projection of the first light-shielding structure 011 on the substrate 1 at least partially overlaps with the orthographic projection of the intervals between the multiple second light-shielding structures 012 on the substrate 1, that is, the first light-shielding structure and the second light-shielding structure are intertwined with each other to fully block the light leakage area, thereby achieving a more ideal effect of preventing light leakage in the non-display area.

[0088] Alternatively, in other embodiments, for example, in the first light leakage region R1, the orthographic projections of the first light-shielding structure 011 and the second light-shielding structure 012, which are adjacent to each other in the direction from the display area 101 to the non-display area 102, on the substrate 1 do not overlap. For example, the orthographic projections of the first light-shielding structure 011 and the second light-shielding structure 012, which are adjacent to each other in the direction from the display area 101 to the non-display area 102, on the substrate 1, which are close to each other, overlap, that is, the close edges are connected. In this way, a technical effect similar to the solution described above in which the orthographic projections of the first light-shielding structure 011 and the second light-shielding structure 012, which are adjacent to each other in the direction from the display area 101 to the non-display area 102, on the substrate 1, partially overlap, can be achieved to prevent light leakage and reflection in the first light leakage region R1.

[0089] For example, the first light shielding structure 011 and the second light shielding structure 012 located in the first light leakage region R1 can be grounded to serve as auxiliary grounding lines. For example, the first light shielding structure 011 and the second light shielding structure 012 are connected to the main ground line GND for grounding. Alternatively, referring to FIG1 , the display panel 10 further includes an integrated circuit board (IC) board 4 located in the non-display region 102, and the first light shielding structure 011 and the second light shielding structure 012 are electrically connected to the integrated circuit board for grounding. Alternatively, the first light shielding structure 011 and the second light shielding structure 012 can also be floating to serve as first floating lines that do not transmit electrical signals. For example, in some embodiments, a portion of the first light shielding structure 011 and a portion of the second light shielding structure 012 are grounded, while another portion of the first light shielding structure 011 and another portion of the second light shielding structure 012 are floating.

[0090] 5 , for example, the display panel 10 further includes a dam member, such as a first dam member Dam1 . The first dam member Dam1 is located in the non-display area 102 and at least partially surrounds the display area 101 . The touch signal line TL is located on a side of the first dam member Dam1 close to the display area 101 to prevent interference of the wiring outside the dam member with the signal transmitted by the touch signal line TL. For example, the first dam glue Dam1 is located on the side of the edge 20 of the light-shielding layer 2 close to the display area 101, and is located on the side of the first part GND1 of the main ground line GND away from the display area 101; multiple first light-shielding structures 011 and multiple second light-shielding structures 012 are respectively arranged at intervals from each other in the direction from the display area 101 to the non-display area 102; multiple first light-shielding structures 011 include a first-part first light-shielding structure and a second-part first light-shielding structure, and multiple second light-shielding structures 012 include a first-part second light-shielding structure and a second-part second light-shielding structure; the first-part first light-shielding structure and the first-part second light-shielding structure are located on the side of the first dam glue Dam1 close to the display area 101, and the second-part first light-shielding structure 011 / 021 and the second-part second light-shielding structure 012 / 022 are located on the side of the first dam glue Dam1 away from the display area 101. In the display panel 10, especially a narrow-frame display panel 10, the distance between the display area 101 and the first dam Dam1 is very small. In the area outside the main ground line GND where a dam, such as the first dam Dam1, is provided, the film layer above the dam is uneven. On the one hand, after testing, in the absence of a light-shielding structure to block light, light leakage and reflection in this uneven area are more severe than in other locations. On the other hand, if the spacing between the multiple first light-shielding structures 011 and second light-shielding structures 012 (e.g., light-shielding lines extending along the first direction D1) extending along the first direction D1 is too small, the exposure machine will not be able to be opened during the photolithography process to fabricate these light-shielding structures, making it difficult to achieve patterning of the first light-shielding structures 011 and the second light-shielding structures 012. Therefore, in the first light-leakage region R1, the spacing between adjacent first light-shielding structures 011 is required to be large, for example, not less than 8 μm. Similarly, the spacing between adjacent second light-shielding structures 012 is also required to be large, for example, not less than 8 μm. For example, in the first light leakage area R1 between the edge of the light shading layer 2 and the main ground line GND, the spacing between adjacent first light shading structures 011 is 8μm to 20μm, and the spacing between adjacent second light shading structures 012 is 8μm to 20μm; for example, the line width of each first light shading structure 011 in the direction from the display area 101 to the non-display area 102 is 8μm to 20μm, and the line width of each second light shading structure 012 in the direction from the display area 101 to the non-display area 102 is 8μm to 20μm.However, even a gap of 8μm still has the risk of light leakage or reflection. In order to completely block the light, multiple first shading structures 011 and multiple second shading structures 012 located in different layers are alternately wired, which can completely block the first light leakage area R1 and prevent light from entering the uneven film layer below the shading structure and causing reflection. As a result, no light will be emitted from the display side of the display panel 10 from the first light leakage area R1. Therefore, in the uneven area where the dam glue is provided, the shading structure 3 adopts a double-layer alternating wiring design, which can significantly and effectively improve the blocking effect, solve the problem of more serious light leakage and reflection in the uneven area, and ensure the production yield of multiple first shading structures and multiple second shading structures in the uneven area.

[0091] For example, the orthographic projection of at least one of the plurality of first light-shielding structures 011 and the plurality of second light-shielding structures 012 on the substrate 1 at least partially overlaps with the orthographic projection of the first dam Dam1 on the substrate 1. For example, in the embodiment shown in FIG5 , the first light-shielding structure 1a (representative of the first light-shielding structure) and the second light-shielding structure 2a and the second light-shielding structure 2b (representative of the second light-shielding structure) all overlap with the orthographic projection of the first dam Dam1 on the substrate 1.

[0092] For example, referring to Figure 5, in the direction perpendicular to the main surface of the substrate 1, the first light-shielding structure 011 is located between the second light-shielding structure 012 and the first dam glue Dam1; the first dam glue Dam1 has an upper surface away from the substrate 1 and a side surface intersecting with the upper surface of the first dam glue Dam1; in the direction perpendicular to the main surface of the substrate 1, the first light-shielding structure 1a at least overlaps with the upper surface of the first dam glue Dam1, and at least one second light-shielding structure 2a / 2b adjacent to the first light-shielding structure 1a overlaps with the first light-shielding structure 011 and overlaps with the side surface of the first dam glue Dam1.

[0093] For example, referring to FIG5 , the side surface of the first dam Dam1 includes a first side surface located on a first side of the first light-shielding structure 1a (e.g., the left side of the first light-shielding structure 1a in FIG5 ) and a second side surface located on a second side of the first light-shielding structure 1a (e.g., the right side of the first light-shielding structure 1a in FIG5 ). The first side and the second side of the first light-shielding structure 1a are opposite in a direction from the display area 101 to the non-display area 102. In a direction perpendicular to the main surface of the substrate 1 , a second light-shielding structure 2a adjacent to the first light-shielding structure 1a on the first side of the first light-shielding structure 1a overlaps with the first light-shielding structure 1a and overlaps with the first side surface of the first dam Dam1. A second light-shielding structure 2b adjacent to the first light-shielding structure 1a on the second side of the first light-shielding structure 1a overlaps with the first light-shielding structure 1a and overlaps with the second side surface of the first dam Dam1. Thus, it is possible to ensure that the uneven area near the first dam Dam1 is completely shielded, thereby ensuring the light-shielding effect in that area.

[0094] For example, referring to Figure 5, the display panel 10 also includes a second dam glue Dam2, which is arranged at intervals with the first dam glue Dam1 and is located on the side of the first dam glue Dam1 away from the display area 101, and a portion of the multiple first shading structures 011 and a portion of the multiple second shading structures 012 are located between the second dam glue Dam2 and the first dam glue Dam1, and another portion of the multiple first shading structures 011 and another portion of the multiple second shading structures 012 overlap with the second dam glue Dam2 in a direction perpendicular to the main surface of the substrate 1, similar to the above-mentioned situation where the first shading structure 011 and the second shading structure 012 overlap with the first dam glue Dam1, which can ensure that the uneven area near the second dam glue Dam2 is completely blocked, ensuring the shading effect of the area, and ensuring that there is no light leakage and reflection in the area between the first dam glue Dam1 and the second dam glue Dam2.

[0095] Here, “a portion of the plurality of first shading structures 011” may be at least one first shading structure 011 among the plurality of first shading structures 011, or a portion of a first shading structure 011; similarly, “a portion of the plurality of second shading structures 012” may be at least one second shading structure 012 among the plurality of second shading structures 012, or a portion of a second shading structure 012.

[0096] Referring to FIG. 2 , for example, the display panel 10 further includes a detection line PCD. The detection line PCD is located in the non-display area 102 and surrounds the display area 101. Both the first and second ends of the detection line PCD are electrically connected to the integrated circuit board 4 to receive a detection signal. The detection line PCD includes a first portion PCD1 that surrounds the display area 101 and extends along the extension direction of the first portion of the touch signal line TL (e.g., along the first direction D1). The first portion PCD1 of the detection line PCD is located on a side of the first portion GND1 of the main ground line GND that is away from the display area 101. After a detection signal is input to the first end of the detection line PCD via the integrated circuit board 4, the signal at the second end of the detection line PCD is detected to determine whether the detection line PCD is intact or has a short circuit, thereby determining whether the area through which the detection line PCD passes is broken, thereby determining whether the area may be at risk of a short circuit. The light shielding structure 3 includes a portion of the first portion PCD1 of the detection line PCD that is close to the display area 101; and / or, the light shielding structure 3 includes a portion of the first portion PCD1 of the detection line PCD that is away from the display area 101. In both cases, light leakage between the detection line PCD and other signal lines can be shielded.

[0097] For example, the detection line PCD and the touch signal line TL, and one of the first light shielding structure 011 / 021 and the second light shielding structure 012 / 022 are disposed in the same layer, for example, these structures disposed in the same layer are made of the same material.

[0098] Referring to Figures 3-4 , for example, the display panel 10 further includes a guard line Guard extending along a first direction D1, which is the same direction as the first portion of the touch signal line TL. For example, the guard line Guard is located between the touch signal line TL and the main ground line GND. The waveform of the electrical signal transmitted by the guard line Guard is substantially the same as that transmitted by the touch signal line TL. The guard line Guard includes a first portion surrounding the display area 101. The guard line Guard prevents signal jumps on the edge of the touch signal line TL.

[0099] For example, the guard line Guard and the touch signal line TL, and one of the first light shielding structure 011 / 021 and the second light shielding structure 012 / 022 are disposed in the same layer, for example, these structures disposed in the same layer are made of the same material.

[0100] 3-4 , for example, the light leakage region includes a second light leakage region R2, which is located between the first portion Guard1 of the guard line Guard and the first portion GND1 of the main ground line GND. For example, the light shielding structure 3 also includes a second partial light shielding structure 02 located in the second light leakage region R2. The second partial light shielding structure 02 is floating and does not transmit electrical signals. The second partial light shielding structure 02 is also a second floating line located between the first portion Guard1 of the guard line Guard and the first portion GND1 of the main ground line GND.

[0101] For example, in some embodiments, the second partial light-shielding structure 02 also includes a first conductive structure 021 and a second conductive structure 022 located in different layers. For example, the first conductive structure 021 is located in the first conductive layer M1, and the second conductive structure 022 is located in the second conductive layer M2.

[0102] For example, the shading structure 3 includes a plurality of first shading structures 021 and a plurality of second shading structures 022 located in the second light leakage area R2. The plurality of first shading structures 021 are arranged along the direction from the display area 101 to the non-display area 102, and the plurality of second shading structures 022 are arranged along the direction from the display area 101 to the non-display area 102. There are gaps between the plurality of first shading structures 021, and there are gaps between the plurality of second shading structures 022.

[0103] For example, in the second light leakage region R2, the orthographic projections of the first light-shielding structure 021 and the second light-shielding structure 022, which are adjacent to each other in the direction from the display area 101 to the non-display area 102, on the substrate 1 do not completely overlap. For example, the orthographic projections of the first light-shielding structure 021 and the second light-shielding structure 022, which are adjacent to each other in the direction from the display area 101 to the non-display area 102, on the substrate 1 partially overlap. In this way, by providing the first conductive structure 021 and the second conductive structure 022, which are respectively located in different layers in the second light leakage region R2, the first conductive structure 021 and the second conductive structure 022 can be allowed to intersect with each other, thereby better shielding the second light leakage region R2 and completely preventing light leakage and reflection from occurring in the second light leakage region R2. For example, the orthographic projection of the second light-shielding structure 022 on the substrate 1 at least partially overlaps with the orthographic projection of the intervals between the multiple first light-shielding structures 021 on the substrate 1; or, the orthographic projection of the first light-shielding structure 021 on the substrate 1 at least partially overlaps with the orthographic projection of the intervals between the multiple second light-shielding structures 022 on the substrate 1, that is, the first light-shielding structure and the second light-shielding structure are intertwined with each other to fully block the light leakage area, thereby achieving a more ideal effect of preventing light leakage in the non-display area.

[0104] Alternatively, in other embodiments, for example, in the second light leakage region R2, the orthographic projections of the first light-shielding structure 021 and the second light-shielding structure 022, which are adjacent to each other in the direction from the display area 101 to the non-display area 102, on the substrate 1 do not overlap. For example, the orthographic projections of the first light-shielding structure 021 and the second light-shielding structure 022, which are adjacent to each other in the direction from the display area 101 to the non-display area 102, on the substrate 1, which are close to each other, overlap, that is, the close edges are connected. In this way, a technical effect similar to the solution described above in which the orthographic projections of the first light-shielding structure 021 and the second light-shielding structure 022, which are adjacent to each other in the direction from the display area 101 to the non-display area 102, on the substrate 1, partially overlap, can be achieved to prevent light leakage and reflection in the first light leakage region R1.

[0105] For example, as shown in FIG4 , in the second light leakage region R2, the line widths of the multiple first light shielding structures 021 in the direction from the display area 101 to the non-display area 102 may be unequal, and the line widths of the multiple second light shielding structures 022 in the direction from the display area 101 to the non-display area 102 may be unequal. Since the width of the second light leakage region R2 in the direction from the display area 101 to the non-display area 102 is much smaller than that of the first light leakage region R1, it is not required that the line widths of the multiple first light shielding structures and / or the multiple second light shielding structures in the second light leakage region R2 be equal. This facilitates the goal of completely blocking the entire second light leakage region R2 as much as possible, and reduces the requirements for the manufacturing process of the first and second light shielding structures. Of course, in other embodiments, the line widths of the multiple first light shielding structures 021 and the multiple second light shielding structures 022 in the second light leakage region R2 may also be equal, and this disclosure is not limited to this.

[0106] For example, referring to Figures 3-4 , the light leakage region includes a third light leakage region R3, which is located between the first portion Guard1 of the guard line Guard and the touch signal line TL. The light shielding structure 3 also includes a third partial light shielding structure 03 located in the third light leakage region R3. The third partial light shielding structure 03 is floating and does not transmit electrical signals. The third partial light shielding structure 03 is also a third floating line located between the first portion Guard1 of the guard line Guard and the touch signal line TL.

[0107] 5 , for example, the display panel 10 further includes an encapsulation layer OC, and the light shielding layer 2 is located on the surface of the encapsulation layer OC. For example, the encapsulation layer OC may be an FMLOC film layer.

[0108] Referring to FIG5 , for example, the light shielding layer 2 is located outside of at least a portion of the dam, away from the display area 101, for example, outside of the first dam Dam1 and the second dam Dam2, away from the display area 101. For example, the dam of the display panel 10 further includes a third dam Dam3, which is located outside of the first dam Dam1 and the second dam Dam2, away from the display area 101. For example, as shown in FIG5 , in a direction perpendicular to the main surface of the substrate 1, the light shielding layer 2 overlaps with the third dam Dam3, and the first light shielding structure 011 and the second light shielding structure 012 both overlap with the third dam Dam3 to completely cover the third dam Dam3.

[0109] For example, in the first light leakage area R1, a plurality of first light shading structures 011 and a plurality of second light shading structures 012 are arranged in an alternating manner to form a whole covering the entire first light leakage area R1, so that the first light leakage area R has no gaps through which light passes, thereby avoiding the phenomenon of light leakage in the non-display area caused by light emitting from the first light leakage area R1.

[0110] Referring to FIG. 5 , for example, the display panel 10 further includes a pixel driving circuit layer (e.g., including, but not limited to, a GOA driving circuit) located in the non-display area 102. The pixel driving circuit layer is configured to control the operation of the display pixels. For example, the pixel driving circuit layer includes driving elements for driving the pixel circuits in the display area 101 to display. These driving elements include transistors, capacitors, and the like. The pixel circuits in the display area 101 include driving transistors, which are configured to drive the light-emitting devices to emit light. For example, the pixel circuits in the display area may also include data transistors and compensation transistors. For example, the pixel driving circuit layer is located on a side of the dam and light-shielding structure 3 that is close to the substrate 1. For example, the pixel driving circuit layer includes multiple signal lines, including signal lines located in the display area and signal lines located in the non-display area. For example, the signal lines located in the display area include multiple data lines, and the multiple data lines provide data signals for controlling the display grayscale of the pixels to multiple columns of pixels in the display area 101. For example, the multiple data lines are located in two different layers in the non-display area, including a first data line Data1 located in a first data transmission layer and a second data line Data2 located in a second data transmission layer. Of course, the data signal configuration is not limited to this configuration, and the routing arrangement of the pixel drive circuit layer in the non-display area is not limited to that shown in FIG5 . For example, referring to FIG5 , the orthographic projections of multiple signal lines located in the non-display area on the main surface of the substrate overlap with the orthographic projections of the light shielding structure 3 on the main surface of the substrate. For example, the signal lines located in the non-display area are located in the fanout area of ​​the display panel 10, and at least a portion of the signal lines located in the non-display area can be electrically connected to the integrated circuit board 4 to provide display drive signals to the pixels in the display area.

[0111] For example, the signal lines located in the non-display area may include a first power line that provides a first power supply voltage to the pixel circuit (e.g., providing a high level VDD) and a second power line that provides a second power supply voltage to the pixel circuit (e.g., providing a low level VSS). For example, the pixel circuit includes: a data line, a light-emitting device, and a driving transistor; the light-emitting device includes a first electrode and a second electrode, the first power line is connected to the first electrode of the light-emitting device to receive the first power supply voltage; the first electrode of the driving transistor is connected to the second power line VDD to receive the second power supply voltage, and the second electrode of the driving transistor is connected to the second electrode of the light-emitting device to receive the second power supply voltage.

[0112] The above-mentioned pixel circuit can refer to a conventional pixel circuit. For example, the pixel circuit can be 3T1C, 7T1C, 5T2C, etc., where T represents a transistor and C represents a capacitor. This application does not limit the type of pixel circuit.

[0113] For example, the signal lines in the non-display area may also include signal lines electrically connected to the data lines to provide data signals. Of course, the signal lines in the non-display area are not limited to the types listed above.

[0114] For example, referring to FIG5 , the pixel definition layer of the display panel 10 further includes a portion of the PDL located in the non-display area 102 , and the display panel 10 further includes a planar layer IDL1 , for example, a light shielding structure 3 , a touch signal line TL, and a main ground line GND are located above the planar layer.

[0115] For example, the display panel 10 provided in the embodiment of the present disclosure may be an OLED touch display panel, such as an FMLOC panel. Of course, the display panel 10 provided in the embodiment of the present disclosure may be an OLED touch display panel or other types of touch display panels.

[0116] Fig. 6 is another schematic diagram of a portion P1 including a light shielding structure in the portion of the non-display area near the first edge shown in Fig. 1. The embodiment shown in Fig. 6 differs from the embodiment shown in Figs. 4-5 in the following ways.

[0117] For example, as shown in FIG6 , the main ground line GND also includes a second portion GND2 connected to its first portion GND1. The extension direction of the second portion GND2 of the main ground line GND intersects the extension direction of the first portion GND1. For example, the first portion GND1 extends along a first direction D1, at least along the first edge 11 of the display panel 10 (as shown in FIG1 ), to align with the extension direction of the multiple touch signal lines TL and effectively utilize limited space. The second portion GND2 extends along a second direction D2 to facilitate connection with the underlying integrated circuit board 4. The integrated circuit board 4 is configured to provide display control drive signals to the display panel 10. The second portion GND2 of the main ground line GND is connected to the integrated circuit board 4, and a ground signal is provided to the main ground line GND via the integrated circuit board 4.

[0118] For example, as shown in Figure 6, the guard line Guard also includes a second portion Guard2 connected to the first portion Guard1. The second portion Guard2 of the guard line Guard extends in a direction that intersects the direction of extension of the first portion Guard1. For example, the first portion Guard1 of the guard line Guard extends along a first direction D1, and the second portion Guard2 of the guard line Guard extends along a second direction D2.

[0119] The touch signal line TL includes a first portion TL1 surrounding the display area 101 and a second portion TL2 connected to the first portion TL1 of the touch signal line TL. The second portion TL2 of the touch signal line TL extends in a direction that intersects with the first portion TL1 of the touch signal line TL. The integrated circuit board 4 includes a plurality of integrated circuit board pins 401. The second portion GND2 of the main ground line GND, the second portion Guard2 of the guard line Guard, and the second portion TL2 of the touch signal line TL are respectively connected to the plurality of integrated circuit board pins 401.

[0120] Referring to FIG. 6 , for example, the display panel 10 further includes a first auxiliary connection portion CS. For example, at least some of the multiple first light-shielding structures 011 are directly connected to the second portion GND2 of the ground line. The first auxiliary connection portion CS is provided on the same layer as the multiple first light-shielding structures 011. The first auxiliary connection portion CS spans the gap between two adjacent first light-shielding structures 011 and connects the two adjacent first light-shielding structures 011. This ensures that the multiple first light-shielding structures 011 have the same ground signal, ensuring signal uniformity across the multiple first light-shielding structures 011 and enhancing the stability of the touch signal transmitted by the touch electrode lines TL located inside the multiple first light-shielding structures 011. Alternatively, the multiple first light-shielding structures can also be directly connected to the second portion GND2 of the ground line. Similarly, a similar auxiliary connection portion can be provided for connecting two adjacent second light-shielding structures 012 located in the second light-shielding layer. For example, the display panel also includes a second auxiliary connection part (not shown in the figure, similar to the structure of the first auxiliary connection part CS), and at least part of the second shading structures 012 in the multiple second shading structures 012 is directly connected to the second part GND2 of the ground line GND; the difference between the second auxiliary connection part and the first auxiliary connection part CS is that the second auxiliary connection part is arranged on the same layer as the multiple second shading structures 012, and the second auxiliary connection part spans the gap between two adjacent second shading structures 012 and connects two adjacent second shading structures 012 to ensure the uniformity of the signals on the multiple second shading structures 012 and enhance the stability of the touch signal transmitted by the touch electrode line TL located inside the multiple second shading structures 012.

[0121] Other features of the embodiment shown in FIG. 6 are the same as those in FIG. 4-5 , and reference may be made to the previous description of FIG. 4-5 .

[0122] FIG7 is another schematic diagram of a portion P1 of the non-display area near the first edge shown in FIG1 , including a light-shielding structure. The embodiment shown in FIG7 differs from the embodiment shown in FIG6 in the following ways. Referring to FIG7 , for example, the light-shielding structure 3 includes a plurality of first light-shielding structures 011 and a plurality of second light-shielding structures 012. Each first light-shielding structure 011 and each second light-shielding structure 012 extend at least partially along a first direction D1. For example, in FIG7 , the portion of each first light-shielding structure 011 extending along the first direction D1 and the portion of each second light-shielding structure 012 extending along the first direction D1 are each strip-shaped and extend along the first direction D1. A second direction D2 intersects the first direction D1, for example, the second direction D2 is perpendicular to the first direction D1, for example, the second direction D2 is from the display area 101 to the non-display area 102 or from the non-display area 102 to the display area 101. The plurality of first light-shielding structures 011 are located in the first light-shielding layer M1, and the plurality of second light-shielding structures 012 are located in the second light-shielding layer M2. For example, in the first light-shielding layer M1, at least some of the first light-shielding structures 011 have portions extending along the first direction D1 interrupted by at least one first opening OP1, and each first light-shielding structure 011 interrupted by the first opening OP1 includes two portions separated by the first opening OP1 in the first direction D1. Similarly, in the second light-shielding layer M2, at least some of the second light-shielding structures 012 have portions extending along the first direction D1 interrupted by at least one second opening OP2, and each second light-shielding structure 012 interrupted by the second opening OP2 includes two portions separated by the second opening OP2 in the first direction D1. This prevents excessive static electricity from accumulating on first and second light-shielding structures 011 and 012 that are too long and could interfere with signals transmitted by nearby touch signal lines TL, thereby facilitating the discharge of static electricity.

[0123] For example, each first light shielding structure 011 can be divided into multiple parts by multiple first openings OP1, and the multiple first openings OP1 are arranged in the first direction D1. For example, two parts separated by one first opening OP1 each include a tip, so as to facilitate the rapid discharge of static electricity on the first light shielding structure 011.

[0124] Similarly, for example, each second light shielding structure 012 can be divided into multiple parts by multiple second openings OP2, and the multiple second openings OP2 are arranged in the first direction D1. For example, two parts separated by one second opening OP2 each include a sharp tip, so as to facilitate the rapid discharge of static electricity on the second light shielding structure 012.

[0125] For example, the orthographic projections of the plurality of first openings OP1 located in the first light-shielding layer M1 and the plurality of second openings OP2 located in the second light-shielding layer M2 on the main surface of the substrate 1 may or may not overlap. For example, in FIG7 , the orthographic projections of the plurality of first openings OP1 and the plurality of second openings OP2 on the main surface of the substrate 1 are interconnected to form a pattern that forms a strip S extending along a third direction. The third direction intersects both the first direction D1 and the second direction D2, facilitating the formation of the aforementioned tips and a regular patterning, thereby reducing the difficulty of manufacturing the mask used for patterning.

[0126] Of course, the specific positions of the plurality of first openings OP1 and the plurality of second openings OP2 are not limited to those shown in FIG. 7 , as long as the first light shielding structure 011 and the second light shielding structure 012 can be respectively divided into a plurality of parts spaced apart in the first direction D1 .

[0127] Other features of the embodiment shown in FIG. 7 are the same as those in FIG. 6 , and reference may be made to the previous description.

[0128] Fig. 8 is another schematic diagram of a portion P1 including a light shielding structure in the portion of the non-display area near the first edge shown in Fig. 1. The embodiment shown in Fig. 8 differs from the embodiments shown in Figs. 4 and 5 in the following ways.

[0129] In Figures 4 and 5 , the first and second light-shielding structures located in the first light-leakage region R1 are both linear, for example, each of these lines including a portion extending along the first direction D1. However, for example, referring to Figure 8 , when the light-shielding structure 3 includes the first and second light-shielding structures located in different layers, at least one of the first and second light-shielding structures located on the side of the first portion GND1 of the main ground line GND away from the display area 101 comprises a solid light-shielding structure. Figure 8 uses the example of a solid light-shielding structure 011. The solid light-shielding structure has a width in the direction from the display area 101 to the non-display area 102 greater than half the distance between the edge of the first portion of the touch signal line TL away from the display area 101 and the edge of the light-shielding layer 2 near the display area 101. This allows the solid light-shielding structure to have a larger width, which helps reduce the difficulty of the manufacturing process. The minimum spacing requirement between adjacent light-shielding structures need not be considered for both flat areas and uneven areas with dams.

[0130] For example, the width of the entire shading structure in the direction from the display area 101 to the non-display area 102 is greater than 1 / 2 of the distance between the edge of the first part GND1 of the main ground line GND away from the display area 101 and the edge of the shading layer 2 close to the display area 101. Similarly, this can ensure that the entire shading structure has a larger width, which is conducive to reducing the difficulty of the manufacturing process. Regardless of whether it is a flat area or an uneven area with a dam glue, there is no need to consider the minimum spacing requirement between adjacent shading structures.

[0131] For example, the width of the entire shading structure in the direction from the display area 101 to the non-display area 102 is also greater than the distance between the edge of the first part Guard1 of the protection line Guard away from the display area 101 and the edge of the first part GND1 of the main ground line GND close to the display area 101. Similarly, this can ensure that the entire shading structure has a larger width, which is conducive to reducing the difficulty of the manufacturing process. Regardless of whether it is a flat area or an uneven area with a dam glue, there is no need to consider the minimum spacing requirement between adjacent shading structures.

[0132] For example, in some embodiments, at least one of the first light shading structure and the second light shading structure located in the first light leakage region R1 includes the above-mentioned whole light shading structure (the whole light shading structure as shown in Figure 8), and the first light shading structure 021 and the second light shading structure 022 located in the second light leakage region R2 are linear (as shown in Figure 4).

[0133] For example, the orthographic projection of the entire light-shielding structure on the main surface of the substrate 1 overlaps (or just touches) with the edge of the light-shielding layer 2 that is close to each other in the direction from the display area 101 to the non-display area 102, or the orthographic projection of the entire light-shielding structure on the main surface of the substrate 1 overlaps with the orthographic projection of the light-shielding layer 2 on the main surface of the substrate 1, so as to more tightly block the first light leakage area R1.

[0134] For example, the entire light-shielding structure is an integrated structure, and a plurality of holes H are provided on the entire light-shielding structure along a direction perpendicular to the main surface of the substrate 1 to increase the air permeability of the entire light-shielding structure. When the material of the entire light-shielding structure is a conductive material such as a metal or an alloy, its air permeability is poor. The provision of a plurality of holes H can prevent the film layer under the entire light-shielding structure, especially the organic film layer, from emitting water vapor that cannot be eliminated when it is heated or humidified, thereby avoiding deformation, warping and other problems of the internal film layer of the display panel caused by this.

[0135] For example, in Figure 8, the plurality of holes H are arranged in a regular array, which is beneficial for improving the uniformity of air permeability and reducing the difficulty of manufacturing. Alternatively, in other embodiments, the arrangement of the plurality of holes H may also be irregular.

[0136] For example, in Figure 8, the area of ​​the entire shading structure is larger than 0.25mm 2 In this case, it is even more necessary to set multiple holes H to improve the air permeability of the entire shading structure.

[0137] For example, for the entire light-shielding structure, the area of ​​the multiple holes H of the entire light-shielding structure accounts for 20% to 60% of the area of ​​the entire light-shielding structure. After experiments and exploration, it was found that if the proportion of the multiple holes H to the area of ​​the entire light-shielding structure is too low, the ideal air permeability cannot be achieved; if the proportion of the multiple holes H to the area of ​​the entire light-shielding structure is too low, the ideal light-shielding effect cannot be achieved. The condition that the area of ​​the multiple holes H of the entire light-shielding structure accounts for 20% to 60% of the area of ​​the entire light-shielding structure can take into account the air permeability without affecting the light-shielding effect.

[0138] For example, in FIG. 8 , the light shielding structure 3 includes a portion of the first portion PCD1 of the detection line PCD away from the display area 101 to shield the light leakage area between the first portion PCD1 of the detection line PCD and other signal lines.

[0139] For example, in FIG8 , the entire light shielding structure can be directly connected to the pin 401 of the integrated circuit board 4 for grounding. For example, the entire light shielding structure further includes a strip portion GND3 extending along the second direction D2. The strip portion GND3 is directly connected to the pin 401 of the integrated circuit board 4 to obtain a ground signal from the integrated circuit board 4.

[0140] For example, the edge of the orthographic projection of the entire light-shielding structure 011 on the main surface of the substrate 1 away from the display area 101 overlaps with the orthographic projection of the light-shielding layer 2 on the main surface of the substrate 1 to achieve a more rigorous light-shielding effect.

[0141] For example, the entire light shielding structure 011 is made of the same material and disposed in the same layer as the first and second sub-touch electrodes, or the entire light shielding structure 011 is made of the same material and disposed in the same layer as the bridge electrode.

[0142] Other features of the embodiment shown in FIG8 are the same as those in FIG7 , and reference may be made to the previous description.

[0143] Fig. 9 is another schematic diagram of a portion P1 including a light shielding structure in the portion of the non-display area near the first edge shown in Fig. 1. The embodiment shown in Fig. 9 differs from the embodiment shown in Fig. 8 in the following ways.

[0144] Referring to Figure 9, for example, the entire shading structure includes a plurality of sub-sections spaced apart from each other, the plurality of sub-sections including a first sub-section S1, a second sub-section S2 and a third sub-section S3, and at least one sub-section is provided with a plurality of holes H passing through the sub-section in a direction perpendicular to the main surface of the substrate 1. For example, each sub-section is provided with a plurality of holes H passing through the sub-section in a direction perpendicular to the main surface of the substrate 1.

[0145] For example, the area of ​​the sub-portion provided with a plurality of via holes H is greater than 0.25 mm 2 In this case, it is even more necessary to set multiple holes H to improve the air permeability of the entire shading structure.

[0146] For example, for the entire light-shielding structure, the area of ​​the multiple holes H of the entire light-shielding structure accounts for 20% to 60% of the area of ​​the entire light-shielding structure. After experiments and exploration, it was found that if the proportion of the multiple holes H to the area of ​​the entire light-shielding structure is too low, the ideal air permeability cannot be achieved; if the proportion of the multiple holes H to the area of ​​the entire light-shielding structure is too low, the ideal light-shielding effect cannot be achieved. The condition that the area of ​​the multiple holes H of the entire light-shielding structure accounts for 20% to 60% of the area of ​​the entire light-shielding structure can take into account the air permeability without affecting the light-shielding effect.

[0147] Other features of the embodiment shown in FIG. 9 are the same as those in FIG. 8 , and reference may be made to the previous description.

[0148] FIG10 is another schematic diagram of a portion P1 of the non-display area near the first edge shown in FIG1 including a light shielding structure. The embodiment shown in FIG10 differs from the embodiment shown in FIG9 in that at least one sub-section is not provided with a via hole, for example, no via hole is provided on each sub-section. No via hole is provided on the first sub-section S1, the second sub-section S2, and the third sub-section S3. For example, the area of ​​the sub-section without a via hole is less than or equal to 0.25 mm 2 , it is not necessary to set vias for sub-parts with smaller areas.

[0149] Other features of the embodiment shown in FIG10 are the same as those in FIG9 , and reference may be made to the previous description.

[0150] Fig. 11 is another schematic diagram of a portion P1 including a light shielding structure in the portion of the non-display area near the first edge shown in Fig. 1. The embodiment shown in Fig. 11 differs from the embodiment shown in Fig. 8 in the following ways.

[0151] 11 , for example, the light shielding structure 3 includes a portion of the first portion PCD1 of the detection line PCD close to the display area 101. Both cases can also shield the light leakage area between the first portion PCD1 of the detection line PCD and other signal lines.

[0152] At least one embodiment of the present disclosure further provides a display panel. Referring to FIG8 , the display panel includes a substrate 1, a touch signal line TL, a light shielding structure 3, and a light shielding layer 2. The substrate 1 includes a display area 101 and a non-display area 102 at least partially surrounding the display area 101. The display area 101 includes display pixels. The substrate 1 has a main surface. The display pixels, the touch signal line TL, the light shielding structure 3, and the multiple dams described below are located on the main surface of the substrate 1. The touch signal line TL is located in the non-display area 102, at least partially surrounds the display area 101, and is configured to provide a touch signal to the display area 101; the touch signal line TL includes a first portion extending along the first direction D1, and the arrangement direction of the touch signal line and the shading structure is the second direction D2, and the first direction D1 intersects with the second direction D2; the shading structure 3 is located in the non-display area 102, at least partially surrounds the display area 101, and is located on the side of the touch signal line TL away from the display area 101; the shading layer 2 is located in the non-display area 102 and at least partially surrounds the display area 101, the touch signal line TL is located on the side of the shading layer 2 close to the display area 101, and the shading structure 3 is located between the shading layer 2 and the first portion of the touch signal line TL; the shading structure 3 includes a whole shading structure 011. The width of the entire light-shielding structure 011 in the direction from the display area 101 to the non-display area 102 is greater than half the distance between the edge of the first portion of the touch signal line TL away from the display area 101 and the edge of the light-shielding layer 2 close to the display area 101. This allows the entire light-shielding structure to have a larger width, which helps reduce the difficulty of the manufacturing process. Regardless of whether it is a flat area or an uneven area with a dam, there is no need to consider the minimum spacing requirement between adjacent light-shielding structures.

[0153] For example, the display panel 10 includes the main ground line GND, and the entire light shielding structure 011 is located on a side of the first portion GND1 of the main ground line GND away from the display area 101. The entire light shielding structure 011 is grounded to serve as an auxiliary ground line. The entire light shielding structure 011 is connected to the main ground line for grounding or is electrically connected to the integrated circuit board for grounding.

[0154] For example, the width of the entire shading structure 011 in the direction from the display area 101 to the non-display area 102 is greater than 1 / 2 of the distance between the edge of the first part GND1 of the first part of the main ground line GND of the touch signal line TL away from the display area 101 and the edge of the shading layer 2 close to the display area 101.

[0155] For example, the display panel 10 includes the above-mentioned protection line Guard, and the width of the entire shading structure in the direction from the display area 101 to the non-display area 102 is also greater than the distance between the edge of the first part Guard1 of the protection line Guard away from the display area 101 and the edge of the first part GND1 of the main ground line GND close to the display area 101.

[0156] For example, the edge of the orthographic projection of the entire light-shielding structure on the main surface of the substrate 1 away from the display area 101 overlaps with the orthographic projection of the light-shielding layer 2 on the main surface of the substrate 1 to achieve a more rigorous light-shielding effect.

[0157] In some embodiments, the light shielding structure in the first light leakage region R1 can also be located on a single layer, i.e., a single-layer configuration. In this case, the aforementioned entire light shielding structure can also be provided. For example, the light shielding structure 3 and the touch signal line TL are made of the same material and are provided on the same layer. The previous embodiment described the case where the light shielding structure shown in FIG8 includes a first light shielding structure and a second light shielding structure located on different layers. The following describes the characteristics that can be met when the light shielding structure in the first light leakage region R1 shown in FIG8 is provided in a single layer.

[0158] For example, the shading structure 3 is only located in one film layer, and the shading structure 3 (including the entire shading structure 011) is made of the same material as the first sub-touch electrode and the second sub-touch electrode and is arranged in the same layer, or the shading structure 3 (including the entire shading structure 011) is made of the same material as the bridge electrode and is arranged in the same layer.

[0159] For example, referring to Figure 8, the entire light-shielding structure 011 overlaps (or just touches) with the orthographic projection of the edge of the light-shielding layer 2 on the main surface of the substrate 1 in the direction from the display area 101 to the non-display area 102, or the orthographic projection of the entire light-shielding structure on the main surface of the substrate 1 overlaps with the orthographic projection of the light-shielding layer 2 on the main surface of the substrate 1, so as to more tightly block the first light leakage area R1.

[0160] For example, the entire light-shielding structure 011 is an integrated structure, and a plurality of holes H are provided on the entire light-shielding structure 011 along a direction perpendicular to the main surface of the substrate 1 to increase the air permeability of the entire light-shielding structure 011. When the material of the entire light-shielding structure is a conductive material such as a metal or an alloy, its air permeability is poor. The provision of a plurality of holes H can prevent the film layer under the entire light-shielding structure, especially the organic film layer, from emitting water vapor that cannot be eliminated when it is heated or humidified, thereby avoiding deformation, warping and other problems of the internal film layer of the display panel caused by this.

[0161] For example, in Figure 8, the plurality of holes H are arranged in a regular array, which is beneficial for improving the uniformity of air permeability and reducing the difficulty of manufacturing. Alternatively, in other embodiments, the arrangement of the plurality of holes H may also be irregular.

[0162] For example, in FIG8 , the area of ​​the entire light shielding structure 011 is larger than 0.25 mm 2 In this case, it is even more necessary to set multiple holes H to improve the air permeability of the entire shading structure.

[0163] For example, for the entire light-shielding structure, the area of ​​the multiple holes H of the entire light-shielding structure accounts for 20% to 60% of the area of ​​the entire light-shielding structure. After experiments and exploration, it was found that if the proportion of the multiple holes H to the area of ​​the entire light-shielding structure is too low, the ideal air permeability cannot be achieved; if the proportion of the multiple holes H to the area of ​​the entire light-shielding structure is too low, the ideal light-shielding effect cannot be achieved. The condition that the area of ​​the multiple holes H of the entire light-shielding structure accounts for 20% to 60% of the area of ​​the entire light-shielding structure can take into account the air permeability without affecting the light-shielding effect.

[0164] For example, in FIG. 8 , the light shielding structure 3 includes a portion of the first portion PCD1 of the detection line PCD away from the display area 101 to shield the light leakage area between the first portion PCD1 of the detection line PCD and other signal lines.

[0165] For example, in FIG8 , the entire light shielding structure 011 can be directly connected to the pin 401 of the integrated circuit board 4 for grounding. For example, the entire light shielding structure further includes a strip portion GND3 extending along the second direction D2. The strip portion GND3 is directly connected to the pin 401 of the integrated circuit board 4 to obtain a ground signal from the integrated circuit board 4.

[0166] It should be noted that, when the light-shielding structure in the first light-leakage region R1 is provided as a single layer, the display panel 10 provided in the embodiment of the present disclosure may also include the aforementioned dams Dam1 to Dam3. Furthermore, in the second and third light-leakage regions R2 and R3, the light-shielding structure may be provided as a single layer, or may include a first light-shielding structure and a second light-shielding structure, each located in a separate layer and overlapping with each other.

[0167] Regardless of whether the light-shielding structure is a single-layer or multi-layer arrangement, multiple light-shielding structures located on the same layer are spaced apart from each other, and the spacing between adjacent light-shielding structures needs to be greater than or equal to 1μm to meet the requirements of the manufacturing process, avoid adjacent light-shielding structures from contacting each other and causing short circuits, and ensure the manufacturing yield of the display panel 10. For example, Figure 12 shows that in the first light leakage region R1, the second light leakage region R2, and the third light leakage region R3, the light-shielding structure 01, the light-shielding structure 02, and the light-shielding structure 03 are all single-layer arrangements, that is, located on the same layer. The spacing between adjacent light-shielding structures 01, the spacing between adjacent light-shielding structures 02, and the spacing between adjacent light-shielding structures 03 need to be greater than or equal to 1μm.

[0168] Figure 13 is a schematic diagram of a display device provided by one embodiment of the present disclosure. As shown in Figure 13, at least one embodiment of the present disclosure further provides a display device 100, which includes any of the display panels 10 provided by the embodiments of the present disclosure. For example, display device 100 can be a display panel, or any product or component with a display function, such as a monitor, an OLED panel, an OLED TV, electronic paper, a mobile phone, a tablet computer, a laptop computer, a digital photo frame, or a navigation system.
