[0062] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0063] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0064] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0065] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. "And / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0066] This disclosure provides a display panel, as shown in Figures 1-8. The display panel may include a display back panel 10 and a touch layer group 5. The display back panel 10 may include a plurality of sub-pixels 35, which include a first sub-pixel 351, a second sub-pixel 352, and a third sub-pixel 353. The spacing between two adjacent second sub-pixels 352 in the second direction Y is greater than the spacing between adjacent first sub-pixels 351 and third sub-pixels 353 in the second direction Y. The touch layer group 5 is disposed on the light-emitting side of the display back panel 10, and the touch layer group 5 includes stacked... The first touch function layer 52 and the second touch function layer 54 are configured. The second touch function layer 54 is configured as a grid structure formed by connecting multiple grid lines 543. The multiple grid lines 543 include a first grid line 5431 and a second grid line 5432 extending along the first direction X. The orthographic projection of a first grid line 5431 on the display back panel 10 is located between an adjacent first sub-pixel 351 and a third sub-pixel 353. The orthographic projection of at least two second grid lines 5432 on the display back panel 10 is located between two adjacent second sub-pixels 352. The first direction X intersects with the second direction Y.

[0067] The display panel disclosed herein reduces the difference between the spacing between the second grid line 5432 and the second sub-pixel 352 in the second direction Y and the spacing between the first grid line 5431 and the first sub-pixel 351 and the third sub-pixel 353 in the second direction Y. This reduces the difference between the light-blocking effect of the second grid line 5432 on the second sub-pixel 352 and the light-blocking effect of the first grid line 5431 on the first sub-pixel 351 and the third sub-pixel 353, thereby mitigating the color shift of the display panel.

[0068] In this example embodiment, referring to FIG1, the display panel may include a display back panel 10, which may include a substrate 1, a driving substrate 2, a light-emitting substrate 3, and an encapsulation layer group 4. The driving substrate 2 can drive the light-emitting substrate 3 to emit light. The driving substrate 2 is disposed on one side of the substrate 1, and the light-emitting substrate 3 is disposed on the side of the driving substrate 2 opposite to the substrate 1. The encapsulation layer group 4 is disposed on the side of the light-emitting substrate 3 opposite to the substrate 1.

[0069] The display back panel 10 can be an OLED (Organic Electroluminescence Display) display back panel 10, a QLED (Quantum Dot Light Emitting Diodes) display back panel 10, a Micro-LED (Micro-light emitting diode) display back panel 10, etc.; the display back panel 10 has a light-emitting side and a non-light-emitting side, which are arranged opposite to each other. The light-emitting side can display the image, and the side displaying the image is the display surface.

[0070] In this example embodiment, taking the OLED display backplane 10 as an example, the driving substrate 2 may include multiple switching units, each of which may include multiple thin-film transistors and capacitors, and the multiple switching units are arranged in an array; a first planarization layer is provided on the side of the multiple switching units away from the substrate 1, and the first planarization layer provides a relatively flat base surface for the film layer to be formed subsequently.

[0071] A light-emitting substrate 3 is disposed on the side of the first planarization layer away from the substrate 1. Referring to FIG1, the light-emitting substrate 3 may include a first electrode 31, a pixel definition layer 32, a light-emitting layer group 33, and a second electrode 34.

[0072] Specifically, a first electrode 31 is provided on the side of the first planarization layer away from the substrate 1. The first electrode 31 is connected to the switching unit of the driving substrate 2. The first electrode 31 can be an anode.

[0073] A pixel definition layer 32 is disposed on the side of the first electrode 31 facing away from the substrate 1. A pixel opening is disposed on the pixel definition layer 32, and a light-emitting layer group 33 is disposed within the pixel opening. A second electrode 34 is disposed on the side of the light-emitting layer group 33 facing away from the substrate 1. The second electrode 34 can be a cathode and is connected to the ground line VSS. The light-emitting layer group 33 within a pixel opening emits light to form a sub-pixel 35. Therefore, the light-emitting layer group 33 within a pixel opening is a sub-pixel 35, such that the orthographic projection of the sub-pixel 35 on the display back panel 10 is the orthographic projection of the light-emitting layer group 33 located within the pixel opening on the display back panel 10. The display back panel 10 can include multiple sub-pixels 35.

[0074] The light-emitting layer group 33 may include a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer stacked sequentially. The hole injection layer is in contact with the first electrode 31, and the electron injection layer is in contact with the second electrode 34. Of course, in other exemplary embodiments of this disclosure, the light-emitting layer group 33 may only include a hole transport layer, a light-emitting layer, and an electron transport layer. The light-emitting layer group 33 may also have other structures, and its specific structure can be set as needed.

[0075] The multiple sub-pixels 35 may include a first sub-pixel 351, a second sub-pixel 352, and a third sub-pixel 353. Specifically, the display back panel 10 may include multiple first sub-pixels 351, multiple second sub-pixels 352, and multiple third sub-pixels 353. The first sub-pixel 351 may be a red sub-pixel 35, that is, the first sub-pixel 351 can emit red light; the second sub-pixel 352 may be a blue sub-pixel 35, that is, the second sub-pixel 352 can emit blue light; and the third sub-pixel 353 may be a green sub-pixel 35, that is, the third sub-pixel 353 can emit green light. Of course, in some other exemplary embodiments of this disclosure, the display back panel 10 may include multiple fourth sub-pixels 35, which may be white sub-pixels 35, that is, the fourth sub-pixel 35 can emit white light; alternatively, the first sub-pixels 351, the second sub-pixels 352, and the third sub-pixels 353 may all emit white light, and then be filtered by a red filter layer, a blue filter layer, and a green filter layer.

[0076] It should be noted that the limitation on the emission color of each sub-pixel 35 is only an example. This disclosure does not make specific limitations on the emission color of each sub-pixel 35. The following description uses the first sub-pixel 351, the second sub-pixel 352, and the third sub-pixel 353 as examples, corresponding to the red sub-pixel R, the blue sub-pixel B, and the green sub-pixel G, respectively.

[0077] The first sub-pixel 351, the second sub-pixel 352, and the third sub-pixel 353 can all be set as rectangular sub-pixels 35. It should be noted that the arrangement and shape of each sub-pixel 35 are merely illustrative examples and do not constitute a limitation of this disclosure.

[0078] In this exemplary embodiment, referring to FIG2, a plurality of first sub-pixels 351 and a plurality of third sub-pixels 353 are alternately arranged along the second direction Y to form a first pixel column, that is, a third sub-pixel 353 is disposed between two adjacent first sub-pixels 351, and a first sub-pixel 351 is disposed between two adjacent third sub-pixels 353. A plurality of second sub-pixels 352 are arranged along the second direction Y to form a second pixel column, and multiple columns of first pixel and multiple columns of second pixel are alternately arranged along the first direction X, that is, a column of second pixel is disposed between two adjacent columns of first pixel, and a column of first pixel is disposed between two adjacent columns of second pixel.

[0079] The spacing between two adjacent second sub-pixels 352 in the second direction Y is greater than the spacing between adjacent first sub-pixels 351 and third sub-pixels 353 in the second direction Y. The spacing between two adjacent second sub-pixels 352 in the second direction Y is greater than or equal to 25 micrometers and less than or equal to 40 micrometers. For example, the spacing between two adjacent second sub-pixels 352 in the second direction Y can be 28 micrometers, 30 micrometers, 32 micrometers, 35 micrometers, 37 micrometers, etc. The spacing between adjacent first sub-pixels 351 and third sub-pixels 353 in the second direction Y is greater than or equal to 15 micrometers and less than or equal to 25 micrometers. For example, the spacing between adjacent first sub-pixels 351 and third sub-pixels 353 in the second direction Y can be 18 micrometers, 20 micrometers, 22 micrometers.

[0080] The display backplane 10 may further include an encapsulation layer group 4. The encapsulation layer group 4 is disposed on the side of the second electrode 34 away from the substrate 1. The encapsulation layer group 4 is used to encapsulate the display backplane 10, preventing external moisture, impurities, etc., from entering the interior of the display backplane 10 and affecting its display effect. The encapsulation layer group 4 can be multi-layered, and may include organic and inorganic layers. Specifically, the encapsulation layer group 4 may include a first inorganic layer, an organic layer disposed on the side of the first inorganic layer away from the substrate 1, and a second inorganic layer disposed on the side of the organic layer away from the substrate 1. The materials of the first inorganic layer, organic layer, and second inorganic layer will not be described further here. Of course, the encapsulation layer group 4 may also include more or fewer layers.

[0081] In this example embodiment, referring to FIG1, a touch layer group 5 is provided on the light-emitting side of the display back panel 10. Specifically, the touch layer group 5 is provided on the side of the encapsulation layer group 4 away from the substrate 1. The touch layer group 5 may include a first touch functional layer 52 and a second touch functional layer 54 stacked together. Both the first touch functional layer 52 and the second touch functional layer 54 are made of metal, which has good electrical conductivity but is opaque. The orthographic projections of the first touch functional layer 52 and the second touch functional layer 54 on the substrate 1 do not overlap with the sub-pixels 35. Specifically, the orthographic projections of the first touch functional layer 52 and the second touch functional layer 54 on the substrate 1 surround the outer periphery of each sub-pixel 35. The second touch functional layer 54 may be configured as a grid structure formed by connecting multiple grid lines 543. The orthographic projection of the grid structure on the substrate 1 surrounds the outer periphery of each sub-pixel 35. This configuration avoids the first touch functional layer 52 and the second touch functional layer 54 from affecting the light emission of each sub-pixel 35.

[0082] However, the inventors discovered that, as shown in FIG1, after setting the touch layer group 5 on the light-emitting side of the display back panel 10, the distance between two adjacent second sub-pixels 352 in the second direction Y is greater than the distance between adjacent first sub-pixels 351 and third sub-pixels 353 in the second direction Y. This results in the distance between the grid line 543 of the second touch function layer 54 and the second sub-pixels 352 in the second direction Y being greater than the distance between the grid line 543 (the grid line 543 shown by the dotted line in the figure) and the first sub-pixels 351 and the third sub-pixels 353 in the second direction Y. Consequently, the grid line 543 has different light-blocking effects on the oblique light. Specifically, the grid line 543 has a weaker light-blocking effect on the second sub-pixels 352, meaning less light is blocked; the grid line 543 has a stronger light-blocking effect on the first sub-pixels 351 and the third sub-pixels 353, meaning more light is blocked. This leads to color shift in the display effect of the display panel.

[0083] In this example embodiment, referring to Figures 2, 5, 7, and 8, the multiple grid lines 543 may include a first grid line 5431 and a second grid line 5432 extending along the first direction X. The orthographic projection of a first grid line 5431 on the display back panel 10 is located between an adjacent first sub-pixel 351 and a third sub-pixel 353, that is, a first grid line 5431 is provided between adjacent first sub-pixels 351 and third sub-pixels 353. The orthographic projection of at least two second grid lines 5432 on the display back panel 10 is located between two adjacent second sub-pixels 352, that is, at least two second grid lines 5432 are provided between two adjacent second sub-pixels 352. For example, two second grid lines 5432 may be provided between two adjacent second sub-pixels 352, three second grid lines 5432 may be provided between two adjacent second sub-pixels 352, or more second grid lines 5432 may be provided between two adjacent second sub-pixels 352.

[0084] This configuration reduces the gap between the distance between the second grid line 5432 and the second sub-pixel 352 in the second direction Y and the distance between the first grid line 5431 and the first sub-pixel 351 and the third sub-pixel 353 in the second direction Y. This reduces the difference between the light-blocking effect of the second grid line 5432 on the second sub-pixel 352 and the light-blocking effect of the first grid line 5431 on the first sub-pixel 351 and the third sub-pixel 353, thereby mitigating the color shift of the display panel.

[0085] In some exemplary embodiments of this disclosure, the distance between the first grid line 5431 and its adjacent first sub-pixel 351 and third sub-pixel 353 in the second direction Y is equal to the distance between the second grid line 5432 and its adjacent second sub-pixel 352 in the second direction Y. Specifically, the distance between the first grid line 5431 and its adjacent first sub-pixel 351 in the second direction Y is a first distance, the distance between the first grid line 5431 and its adjacent third sub-pixel 353 in the second direction Y is a third distance, and the distance between the second grid line 5432 and its adjacent second sub-pixel 352 in the second direction Y is a second distance. The first distance, the second distance, and the third distance are the same. Even if the first grid line 5431 and at least two second grid lines 5432 are centered between two adjacent sub-pixels 35, the light-blocking effect of the first grid line 5431 on the adjacent first sub-pixels 351 and third sub-pixels 353 on both sides is basically the same, and the light-blocking effect of the second grid line 5432 on the two adjacent second sub-pixels 352 on both sides is basically the same. Moreover, the light-blocking effect of the first grid line 5431 on the adjacent first sub-pixels 351 and third sub-pixels 353 on both sides is also basically the same as the light-blocking effect of the second grid line 5432 on the two adjacent second sub-pixels 352 on both sides, thereby avoiding color shift caused by the second touch function layer 54.

[0086] It should be noted that the above equal spacing is not simply perfectly equal, but can have a certain degree of error. The error range varies depending on the equipment and preparation process. Therefore, within the error range of the equipment and preparation process, the spacing is considered to be equal.

[0087] The touch layer group 5 may include a plurality of first touch electrodes 541 and a plurality of second touch electrodes 542.

[0088] Multiple first touch electrodes 541 can be connected sequentially along the second direction Y to form a first touch unit having a line shape extending along the second direction Y, and the multiple first touch units are arranged sequentially along the first direction X.

[0089] Multiple second touch electrodes 542 can be connected sequentially along the first direction X to form a second touch unit having a line shape extending along the first direction X, and the multiple second touch units are arranged sequentially along the second direction Y.

[0090] It should be noted that in this disclosure, the first direction X intersects with the second direction Y, for example, the first direction X is perpendicular to the second direction Y.

[0091] Multiple first touch electrodes 541 and multiple second touch electrodes 542 constitute M rows of driving electrodes * N columns of sensing electrodes, that is, including M first touch electrodes 541 and N second touch electrodes 542, where M and N are positive integers greater than two.

[0092] In some exemplary embodiments, the first touch electrode 541 and the second touch electrode 542 may have a rhomboid shape, such as a regular rhombus, a horizontally elongated rhombus, or a vertically elongated rhombus. Furthermore, the dividing line between the first touch electrode 541 and the second touch electrode 542 may be a curve; for example, the dividing line may be a broken line, such that the edges of the first touch electrode 541 and the second touch electrode 542 form a stepped shape. The dividing line between the first touch electrode 541 and the second touch electrode 542 is formed by connecting the two electrodes through a broken line opening. In some possible implementations, the first touch electrode 541 and the second touch electrode 542 may have any one or more of the following shapes: triangle, square, trapezoid, parallelogram, pentagon, hexagon, and other polygons; this disclosure does not limit the specific shape.

[0093] One of the first touch unit and the second touch unit serves as a touch driving unit, which receives touch driving signals, while the other serves as a touch sensing unit, which generates touch sensing signals when there is a touch action.

[0094] The specific touch control principle is as follows: The second touch electrode 542 and the first touch electrode 541 can form a capacitor, and multiple first touch electrodes 541 and multiple second touch electrodes 542 can form multiple capacitors (e.g., C1, C2, C3, ...). Each capacitor is located at a different position in the display area AA; that is, in the coordinate system formed by the first direction X and the second direction Y, each capacitor is located at a different coordinate point. The touch driver chip transmits a touch drive signal (e.g., a trigger signal) to the first touch trace, and the touch drive signal is transmitted to the first touch electrode 541 through the first touch trace. At this time, each capacitor at the aforementioned different positions will have an initial capacitance value. Since the human body is a conductor, when a person's finger touches a certain position on the display panel, the capacitance value of the capacitor at that position will change. Based on the amount of change in capacitance value, the second touch electrode 542 at that position will receive a corresponding touch sensing signal (e.g., a receive signal). The touch sensing signal on the second touch electrode 542 at that position is transmitted to the touch driver chip through the second touch trace. The capacitance of the capacitors at untouched locations remains unchanged. Therefore, by determining the capacitance values ​​of each capacitor, the touch point can be identified, thus enabling touch functionality. Of course, the functions of the first touch electrode 541 and the first touch trace can be interchanged with those of the second touch electrode 542 and the second touch trace.

[0095] In this example embodiment, referring to FIG1, the touch layer group 5 may include a base layer 51, a first touch functional layer 52, a touch insulating layer 53, a second touch functional layer 54, and a protective layer 55. The base layer 51 is disposed on the light-emitting side of the display back panel 10. Specifically, the base layer 51 is disposed on the side of the encapsulation layer group 4 away from the substrate 1, and the material of the base layer 51 is generally SiNx. The first touch functional layer 52 is disposed on the side of the base layer 51 away from the display back panel 10. The first touch functional layer 52 may be a Ti / Al / Ti three-layer structure, an ITO / Ag / ITO three-layer structure, etc. The touch insulating layer 53 is disposed on the side of the first touch functional layer 52 away from the base layer 51. The touch insulating layer 53 has multiple vias, and the material of the touch insulating layer 53 is generally SiNx. The second touch functional layer 54 is disposed on the side of the touch insulating layer 53 facing away from the substrate layer 51. The second touch functional layer 54 can be a Ti / Al / Ti, ITO / Ag / ITO three-layer structure, etc. The protective layer 55 is disposed on the side of the second touch functional layer 54 facing away from the substrate 1, and the material of the protective layer 55 is PI (polyimide). Of course, the materials and structures of the above-mentioned film layers are only illustrative examples, and can be selected and configured as needed.

[0096] Referring to FIG2, the second touch function layer 54 may include a first touch electrode 541 and a second touch electrode 542, such that the first touch electrode 541 and the second touch electrode 542 are far away from the display back panel 10, thereby reducing or even avoiding the influence of the display signal of the display back panel 10 on the touch signal.

[0097] Specifically, a first disconnection opening 5435 is provided on the second touch functional layer 54. The first disconnection opening 5435 divides the mesh structure to form at least a first touch electrode 541 and a second touch electrode 542. For example, the first disconnection opening 5435 can divide the second touch functional layer 54 into a dummy part, a first touch electrode 541, and a second touch electrode 542. The dummy part is generally not electrically connected to the outside and does not need to be conductive.

[0098] A first break opening 5435 is provided on a portion of the second grid line 5432, so that one end of this portion of the second grid line 5432 can be a first touch electrode 541, and the other end of this portion of the second grid line 5432 can be a second touch electrode 542. The first break openings 5435 on at least two second grid lines 5432 located between two adjacent second sub-pixels 352 are staggered. For example, when two second grid lines 5432 are provided between two adjacent second sub-pixels 352, the first break opening 5435 on one second grid line 5432 is closer to the first touch electrode 541, and the first break opening 5435 on the other second grid line 5432 is closer to the second touch electrode 542. When three second grid lines 5432 are provided between two adjacent second sub-pixels 352, the first break opening 5435 on one second grid line 5432 is closer to the first touch electrode 541, the first break opening 5435 on another second grid line 5432 is basically located in the middle, and the first break opening 5435 on yet another second grid line 5432 is closer to the second touch electrode 542. Of course, it can also be configured that three first break openings 5435 are connected to form a ">" or "<" structure. This setting can prevent at least two first line break openings 5435 from being observed, especially under strong light, which is beneficial for shadow removal.

[0099] In some exemplary embodiments of this disclosure, referring to Figures 2 and 3, the plurality of grid lines 543 may further include a third grid line 5433 and a fourth grid line 5434 extending along the first direction X. The touch layer group 5 may include a connection structure 5a, which may include a start segment 5a1 and an end segment 5a2. The first touch function layer 52 may include a bridging portion 521, which may include a sub-start segment 5211 and a sub-end segment 5213. The start segment 5a1 may include the sub-start segment 5211 and a third grid line 5433 interconnected through a first via 531, so that the start segment 5a1 is configured as a double-layer structure to reduce the resistance of the start segment 5a1 and reduce the attenuation of the touch signal, thereby ensuring the uniformity of the touch effect throughout the display panel. The end segment 5a2 may include the sub-end segment 5213 and a fourth grid line 5434 interconnected through a second via 532, so that the end segment 5a2 is configured as a double-layer structure to reduce the resistance of the end segment 5a2 and reduce the attenuation of the touch signal, thereby ensuring the uniformity of the touch effect throughout the display panel. The first via 531 and the second via 532 are disposed on the touch insulating layer 53.

[0100] Of course, in some other exemplary embodiments of this disclosure, the multiple grid lines 543 may also include a third grid line 5433 or a fourth grid line 5434 extending along the first direction X. When the third grid line 5433 is included, the start segment 5a1 may include a sub-start segment 5211 and the third grid line 5433 interconnected through a first via 531, such that the start segment 5a1 is configured as a double-layer structure to reduce the resistance of the start segment 5a1, mitigate the attenuation of the touch signal, and ensure the uniformity of the touch effect across the display panel. When the fourth grid line 5434 is included, the end segment 5a2 may include a sub-end segment 5213 and the fourth grid line 5434 interconnected through a second via 532, such that the end segment 5a2 is configured as a double-layer structure to reduce the resistance of the end segment 5a2, mitigate the attenuation of the touch signal, and ensure the uniformity of the touch effect across the display panel.

[0101] Referring to Figures 2 and 3, the third grid line 5433 and the fourth grid line 5434 are included in different second touch electrodes 542. Specifically, the third grid line 5433 and the fourth grid line 5434 belong to two adjacent second touch electrodes 542. The third grid line 5433 is connected to the bridging portion 521 through the first via 531, and the fourth grid line 5434 is connected to the bridging portion 521 through the second via 532. The bridging portion 521 connects the third grid line 5433 and the fourth grid line 5434, thereby connecting two adjacent second touch electrodes 542 through the connection structure 5a, so that touch signals can be transmitted between the two adjacent second touch electrodes 542.

[0102] Alternatively, the orthographic projection of the third grid line 5433 on the display back panel 10 may overlap with the orthographic projection of the sub-start segment 5211 on the display back panel 10. For example, the orthographic projection of the third grid line 5433 on the display back panel 10 may be located within the orthographic projection of the sub-start segment 5211 on the display back panel 10, or the orthographic projection of the sub-start segment 5211 on the display back panel 10 may be located within the orthographic projection of the third grid line 5433 on the display back panel 10, or a portion of the orthographic projection of the sub-start segment 5211 on the display back panel 10 may overlap with a portion of the orthographic projection of the third grid line 5433 on the display back panel 10.

[0103] Alternatively, the orthographic projection of the fourth grid line 5434 on the display back panel 10 may overlap with the orthographic projection of the sub-end segment 5213 on the display back panel 10. For example, the orthographic projection of the fourth grid line 5434 on the display back panel 10 may be located within the orthographic projection of the sub-end segment 5213 on the display back panel 10, or the orthographic projection of the sub-end segment 5213 on the display back panel 10 may be located within the orthographic projection of the fourth grid line 5434 on the display back panel 10, or a portion of the orthographic projection of the sub-end segment 5213 on the display back panel 10 may overlap with a portion of the orthographic projection of the fourth grid line 5434 on the display back panel 10.

[0104] Alternatively, the third grid line 5433 may include at least a portion of at least one of the first grid lines 5431. For example, the third grid line 5433 may include one of the first grid lines 5431, or the third grid line 5433 may include two or more of the first grid lines 5431. In this case, the third grid line 5433 is configured as two or more segments spaced apart, and both or more segments are connected to the sub-start segment 5211 through the first via 531; or the third grid line 5433 may include a portion of one of the first grid lines 5431.

[0105] In some other exemplary embodiments of this disclosure, the third grid line 5433 may include at least a portion of at least one of the second grid lines 5432. For example, the third grid line 5433 may include one of the second grid lines 5432, or the third grid line 5433 may include two or more of the second grid lines 5432. In this case, the third grid line 5433 is configured as two or more segments spaced apart, and both or more segments are connected to the sub-start segment 5211 through the first via 531; or the third grid line 5433 may include a portion of one of the second grid lines 5432.

[0106] Alternatively, the fourth grid line 5434 may include at least a portion of at least one of the first grid lines 5431. For example, the fourth grid line 5434 may include one of the first grid lines 5431, or the fourth grid line 5434 may include two or more of the first grid lines 5431. In this case, the fourth grid line 5434 is configured as two or more segments spaced apart, and both or more segments are connected to the sub-end segment 5213 through the second via 532; or the fourth grid line 5434 may include a portion of one of the first grid lines 5431.

[0107] In some other exemplary embodiments of this disclosure, the fourth grid line 5434 may include at least a portion of at least one of the second grid lines 5432. For example, the fourth grid line 5434 may include one of the second grid lines 5432, or the fourth grid line 5434 may include two or more of the second grid lines 5432. In this case, the fourth grid line 5434 is configured as two or more segments spaced apart, and both segments are connected to the sub-end segment 5213 through the second via 532; or the fourth grid line 5434 may include a portion of one of the second grid lines 5432.

[0108] Referring to FIG2, when the bridging portion 521 is configured as a rectangular sawtooth structure, the third grid line 5433 and the fourth grid line 5434 may not be on the same straight line. This arrangement also ensures that the first via 531 and the second via 532 used for bridging are not on the same straight line. Of course, in some other exemplary embodiments of this disclosure, the third grid line 5433 and the fourth grid line 5434 may be on the same straight line, such that the first via 531 and the second via 532 used for bridging are also on the same straight line.

[0109] Referring to FIG5, when the bridging portion 521 is configured as a straight line extending along the first direction X, the third grid line 5433 and the fourth grid line 5434 are generally located on the same straight line.

[0110] Referring to Figures 2 and 5, the bridging portion 521 may further include an intermediate segment 5212, which connects the sub-start segment 5211 and the sub-end segment 5213. Since the intermediate segment 5212 needs to span at least two columns of pixels, a portion of the orthographic projection of the intermediate segment 5212 on the display back panel 10 is located between two adjacent second sub-pixels 352, and a portion of the orthographic projection of the intermediate segment 5212 on the display back panel 10 is located between adjacent first sub-pixels 351 and third sub-pixels 353.

[0111] The orthographic projection of the middle segment 5212 on the display back panel 10 does not overlap with the orthographic projection of the first grid line 5431 on the display back panel 10. That is, the first grid line 5431 is not provided at the position directly opposite to the middle segment 5212; for example, the first grid line 5431 at the position directly opposite to the middle segment 5212 can be removed. Similarly, the orthographic projection of the middle segment 5212 on the display back panel 10 does not overlap with the orthographic projection of the second grid line 5432 on the display back panel 10. That is, the second grid line 5432 is not provided at the position directly opposite to the middle segment 5212; for example, the second grid line 5432 at the position directly opposite to the middle segment 5212 can be removed. This arrangement reduces the overlap area between the bridging portion 521 and the first touch electrode 541, thereby reducing the parasitic capacitance value between the bridging portion 521 and the first touch electrode 541 and improving the touch effect.

[0112] Referring to Figures 2 and 4, the bridging portion 521 can be configured as a rectangular sawtooth structure, with the bridging portion 521 as a linear structure extending along the first direction X. Specifically, the bridging portion 521 may include multiple first segments 5217 and multiple second segments 5218. The first segments 5217 extend along the first direction X, and the second segments 5218 extend along the second direction Y. Adjacent first segments 5217 are not on the same straight line, and adjacent second segments 5218 are not on the same straight line. The multiple first segments 5217 and multiple second segments 5218 are alternately connected; that is, a second segment 5218 connects adjacent first segments 5217, and a first segment 5217 connects adjacent second segments 5218. This configuration avoids the bridging portion 521 from being observed, especially under strong light, thus facilitating shadow removal.

[0113] The orthographic projection of the second segment 5218 on the display back panel 10 overlaps with the orthographic projection of the grid line 543 extending along the second direction Y in the second touch function layer 54 on the display back panel 10. For example, the orthographic projection of the second segment 5218 on the display back panel 10 may be located within the orthographic projection of the grid line 543 extending along the second direction Y in the second touch function layer 54 on the display back panel 10; alternatively, the orthographic projection of the grid line 543 extending along the second direction Y in the second touch function layer 54 on the display back panel 10 may be located within the orthographic projection of the second segment 5218 on the display back panel 10; or a portion of the orthographic projection of the second segment 5218 on the display back panel 10 may overlap with a portion of the orthographic projection of the grid line 543 extending along the second direction Y in the second touch function layer 54 on the display back panel 10. This avoids the second segment 5218 affecting the light emission efficiency of each sub-pixel 35.

[0114] Alternatively, the bridging portion 521 is equidistant from two adjacent sub-pixels 35 on either side of the second direction Y. Specifically, when the orthographic projection of the bridging portion 521 is located between two adjacent first sub-pixels 351 and third sub-pixels 353 in the second direction Y, the distance between the bridging portion 521 and the adjacent first sub-pixel 351 in the second direction Y is equal to the distance between the bridging portion 521 and the adjacent third sub-pixel 353 in the second direction Y; when the orthographic projection of the bridging portion 521 is located between two adjacent second sub-pixels 352 in the second direction Y, the distance between the bridging portion 521 and the two adjacent second sub-pixels 352 in the second direction Y is the same. This ensures that the bridging portion 521 is centrally located in the second direction Y, allowing it to form touch capacitance with both the bridging portion 521 and the first touch electrodes 541 on either side, thereby increasing the touch capacitance between the bridging portion 521 and the first touch electrodes 541 and improving the touch signal quantity.

[0115] Referring to FIG5, in some example embodiments of this disclosure, the bridging portion 521 may be configured as a straight structure extending along the first direction X.

[0116] Alternatively, the bridging portion 521 is equidistant from the first sub-pixel 351 and the third sub-pixel 353 adjacent to each other on both sides of the second direction Y, that is, the distance between the bridging portion 521 and the first sub-pixel 351 on one side of the second direction Y is equal to the distance between the bridging portion 521 and the third sub-pixel 353 on the other side of the second direction Y.

[0117] The bridging portion 521 is at a different distance from the two adjacent second sub-pixels 352 on both sides of the second direction Y in the second direction Y. That is, the distance between the bridging portion 521 and the second sub-pixel 352 on one side of the second direction Y in the second direction Y is not equal to the distance between the bridging portion 521 and the second sub-pixel 352 on the other side of the second direction Y in the second direction Y.

[0118] Of course, in some other exemplary embodiments of this disclosure, when the bridging portion 521 is configured as a straight line structure extending along the first direction X, the distance between the bridging portion 521 and the two adjacent sub-pixels 35 on both sides of the second direction Y can also be the same in the second direction Y.

[0119] Alternatively, when the bridging portion 521 is configured with either of the above two structures, the distance between the bridging portion 521 and the two adjacent sub-pixels 35 on both sides of the first direction X can be the same, or it can be different, which will not be elaborated here.

[0120] Referring to Figure 6, the bridging portion 521 forms a raised structure protruding from the base layer 51. After covering the touch insulating layer 53, since the touch insulating layer 53 is made of inorganic material and is relatively thin, it cannot flatten the bridging portion 521, resulting in a raised structure on the side of the touch insulating layer 53 facing away from the display back panel 10. When forming the second touch functional layer 54, it is first fully covered and then patterned to form a grid structure of the second touch functional layer 54. However, the second touch functional layer 54 at the bottom corner of the raised structure is not easily removed, forming a residual portion Rem. The residual portion Rem extends along the extension direction of the bridging portion 521, causing the residual portion Rem to electrically connect the first touch electrode 541 and the second touch electrode 542, resulting in a short circuit.

[0121] In some exemplary embodiments of this disclosure, referring to FIG7, a second break opening 5436 is provided on the grid line 543 of the first touch electrode 541 near the second touch electrode 542. Specifically, for the first touch electrode 541 located at the edge, the second touch electrode 542 is provided only on one side in the first direction X. Therefore, the second break opening 5436 can be provided on the grid line 543 on the side of the first touch electrode 541 near the second touch electrode 542. For the first touch electrode 541 located in the middle (not the edge, i.e., the middle), the second touch electrode 542 is provided on both sides in the first direction X. Therefore, the second break opening 5436 can be provided on the grid line 543 on both sides of the first touch electrode 541 near the second touch electrode 542.

[0122] The second break opening 5436 may be provided only on the grid line 543 extending along the second direction Y; or the second break opening 5436 may be provided not only on the grid line 543 extending along the second direction Y, but also on the grid line 543 extending along the first direction X, and the second break openings 5436 at these two locations may be connected as one unit. For example, the second break opening 5436 may be provided at the corner of the grid.

[0123] The orthographic projection of the bridging portion 521 on the display back panel 10 overlaps with the orthographic projection of the second break opening 5436 on the display back panel 10. For example, a portion of the orthographic projection of the bridging portion 521 on the display back panel 10 may be located within the orthographic projection of the second break opening 5436 on the display back panel 10, and the orthographic projection of the bridging portion 521 on the display back panel 10 and the orthographic projection of the second break opening 5436 on the display back panel 10 may have a non-zero gap, such that the bridging portion 521 passes through the second break opening 5436 when viewed from a top view; or a portion of the orthographic projection of the bridging portion 521 on the display back panel 10 may overlap with a portion of the orthographic projection of the second break opening 5436 on the display back panel 10. This configuration ensures that even if residual portions Rem are formed on both sides of the bridging portion 521 in the width direction, the residual portions Rem will extend to the second disconnection opening 5436, increasing the path of the residual portions Rem and reducing or even avoiding the probability of the residual portions Rem connecting with the first touch electrode 541. This reduces or even avoids the probability of the residual portions Rem electrically connecting the first touch electrode 541 and the second touch electrode 542, resulting in a short circuit.

[0124] Alternatively, when the bridging portion 521 is configured as a rectangular sawtooth structure, the orthographic projection of the second break opening 5436 on the display back panel 10 overlaps with the orthographic projection of the bend portion of the bridging portion 521 on the display back panel 10. For example, a portion of the orthographic projection of the second break opening 5436 on the display back panel 10 overlaps with a portion of the orthographic projection of the bend portion of the bridging portion 521 on the display back panel 10, or the orthographic projection of the bend portion of the bridging portion 521 on the display back panel 10 is located within the orthographic projection of the second break opening 5436 on the display back panel 10. This configuration not only increases the path of the residual part Rem, but also makes it easy for the residual part Rem to break at the bend because it needs to follow the bridging part 521 to make a turn. The second disconnection opening 5436 is set at this point to further prevent the disconnected residual part Rem from connecting with the first touch electrode 541, thereby avoiding the possibility of the residual part Rem electrically connecting the first touch electrode 541 and the second touch electrode 542 and causing a short circuit.

[0125] In some other exemplary embodiments of this disclosure, referring to FIG8, the second touch electrode 542 is provided with a third break opening 5437 on the grid line 543 on at least one side near the first touch electrode 541. Specifically, for the second touch electrode 542 located at the edge, the first touch electrode 541 is provided only on one side in the first direction X. Therefore, the third break opening 5437 can be provided on the grid line 543 on the side of the second touch electrode 542 near the first touch electrode 541. For the second touch electrode 542 located in the middle (not the edge, which is the middle), the first touch electrode 541 is provided on both sides in the first direction X. Therefore, the third break opening 5437 can be provided on the grid line 543 on both sides of the second touch electrode 542 near the first touch electrode 541.

[0126] The third break opening 5437 may be provided only on the grid line 543 extending along the second direction Y; or the third break opening 5437 may be provided not only on the grid line 543 extending along the second direction Y, but also on the grid line 543 extending along the first direction X, and the third break openings 5437 at these two locations may be connected as one unit. For example, the third break opening 5437 may be provided at the corner of the grid.

[0127] The orthographic projection of the bridging portion 521 on the display back panel 10 overlaps with the orthographic projection of the third break opening 5437 on the display back panel 10. For example, a portion of the orthographic projection of the bridging portion 521 on the display back panel 10 may be located within the orthographic projection of the third break opening 5437 on the display back panel 10, and the orthographic projection of the bridging portion 521 on the display back panel 10 and the orthographic projection of the third break opening 5437 on the display back panel 10 may have a non-zero gap, such that the bridging portion 521 passes through the third break opening 5437 when viewed from a top view; or a portion of the orthographic projection of the bridging portion 521 on the display back panel 10 may overlap with a portion of the orthographic projection of the third break opening 5437 on the display back panel 10. This configuration ensures that even if residual portions Rem are formed on both sides of the bridging portion 521 in the width direction, the residual portions Rem will extend to the third disconnection opening 5437, increasing the path of the residual portions Rem and reducing or even avoiding the probability of the residual portions Rem connecting with the second touch electrode 542. This reduces or even avoids the probability of the residual portions Rem electrically connecting the first touch electrode 541 and the second touch electrode 542, resulting in a short circuit.

[0128] Alternatively, when the bridging portion 521 is configured as a rectangular sawtooth structure, the orthographic projection of the third break opening 5437 on the display back panel 10 overlaps with the orthographic projection of the bend portion of the bridging portion 521 on the display back panel 10. For example, a portion of the orthographic projection of the third break opening 5437 on the display back panel 10 overlaps with a portion of the orthographic projection of the bend portion of the bridging portion 521 on the display back panel 10, or the orthographic projection of the bend portion of the bridging portion 521 on the display back panel 10 is located within the orthographic projection of the third break opening 5437 on the display back panel 10. This configuration not only increases the path of the residual part Rem, but also makes it easy for the residual part Rem to break at the bend because it needs to follow the bridging part 521 to make a turn. Fortunately, the third disconnection opening 5437 is set here to further prevent the disconnected residual part Rem from connecting with the first touch electrode 541, thereby avoiding the possibility of the residual part Rem electrically connecting the first touch electrode 541 and the second touch electrode 542 and causing a short circuit.

[0129] This disclosure also provides a display panel, as shown in Figures 1-8. The display panel may include a display back panel 10 and a touch layer group 5. The display back panel 10 may include a plurality of sub-pixels 35, which include a first sub-pixel 351, a second sub-pixel 352, and a third sub-pixel 353. The spacing between two adjacent second sub-pixels 352 in the second direction Y is greater than the spacing between adjacent first sub-pixels 351 and third sub-pixels 353 in the second direction Y. The touch layer group 5 is disposed on the light-emitting side of the display back panel 10. The touch layer group 5 includes a first touch function layer 52 and a second touch function layer 54 stacked together. The second touch function layer 54 is configured with a plurality of grid lines 5 The grid structure formed by the connection of 43 includes multiple grid lines 543, including second grid lines 5432 extending along the first direction X. The orthographic projection of at least two second grid lines 5432 on the display back panel 10 is located between two adjacent second sub-pixels 352. The first direction X intersects with the second direction Y. A first break opening 5435 is provided on the second touch function layer 54. The first break opening 5435 divides the grid structure into at least a first touch electrode 541 and a second touch electrode 542. A portion of the second grid lines 5432 are provided with the first break opening 5435. The first break openings 5435 on at least two second grid lines 5432 located between two adjacent second sub-pixels 352 are staggered.

[0130] The display panel disclosed herein reduces the spacing between the second grid line 5432 and the second sub-pixel 352 in the second direction Y, thereby enhancing the light-blocking effect of the second grid line 5432 on the second sub-pixel 352 and thus reducing the color shift of the display panel; the misaligned setting of the first broken line opening 5435 can prevent at least two first broken line openings 5435 from being observed, especially under strong light, which is beneficial for shadow removal.

[0131] It should be noted that the specific structures in the above example implementations can all be applied to this example implementation, and will not be repeated here.

[0132] This disclosure also provides a display panel, as shown in Figures 1-8. The display panel may include a display back panel 10 and a touch layer group 5. The display back panel 10 may include a plurality of sub-pixels 35, which include a first sub-pixel 351, a second sub-pixel 352, and a third sub-pixel 353. The spacing between two adjacent second sub-pixels 352 in the second direction Y is greater than the spacing between adjacent first sub-pixels 351 and third sub-pixels 353 in the second direction Y. The touch layer group 5 is disposed on the light-emitting side of the display back panel 10. The touch layer group 5 includes a first touch function layer 52 and a second touch function layer 54 stacked together. The second touch function layer 54 is configured as a grid structure formed by connecting a plurality of grid lines 543. The plurality of grid lines 543 include second grid lines 5432 extending along the first direction X. The orthographic projection of at least two second grid lines 5432 on the display back panel 10 is located between two adjacent second sub-pixels 352. The first direction X intersects the second direction Y.

[0133] The second touch functional layer 54 includes at least a first touch electrode 541 and a second touch electrode 542. Multiple grid lines 543 include a third grid line 5433 and / or a fourth grid line 5434 extending along a first direction X. The touch layer group 5 may include a connection structure 5a, which may include a start segment 5a1 and an end segment 5a2. The first touch functional layer 52 may include a bridging portion 521, which may include a sub-start segment 5211 and a sub-end segment 5213. The start segment 5a1 includes a sub-start segment 5211 and a third grid line 5433 interconnected through a first via 531. The end segment 5a2 may include a sub-end segment 5213 and a fourth grid line 5434 interconnected through a second via. The third grid line 5433 and the fourth grid line 5434 are included in different second touch electrodes 542. At least one of the third grid line 5433 and the fourth grid line 5434 is at least a portion of at least one of the second grid lines 5432.

[0134] The display panel disclosed herein reduces the spacing between the second grid line 5432 and the second sub-pixel 352 in the second direction Y, thereby enhancing the light-blocking effect of the second grid line 5432 on the second sub-pixel 352 and reducing the color shift of the display panel; the start segment 5a1 and / or end segment 5a2 are set as a double-layer structure to reduce the resistance of the start segment 5a1 and / or end segment 5a2, reduce the attenuation of the touch signal, and ensure the uniformity of the touch effect throughout the display panel.

[0135] It should be noted that the specific structures in the above example implementations can all be applied to this example implementation, and will not be repeated here.

[0136] This disclosure also provides a display panel, as shown in Figures 9-16. The display panel may include a display back panel 10 and a touch layer group 5. The display back panel 10 may include a plurality of sub-pixels 35. The touch layer group 5 is disposed on the light-emitting side of the display back panel 10. The touch layer group 5 may include a first touch functional layer 52, a touch insulating layer 53, and a second touch functional layer 54 stacked together. The first touch functional layer 52 is configured as a first grid structure 52a formed by connecting a plurality of first grid lines 5431. The orthographic projection of the first grid structure 52a on the display back panel 10 does not overlap with the sub-pixels 35. The second touch functional layer 54 is configured as a second grid line 5432 connected together. The second mesh structure 54a is formed, and its orthographic projection on the display back panel 10 does not overlap with the sub-pixel 35. The first mesh structure 52a may include a first connecting portion 52a1, and the second mesh structure 54a may include a second connecting portion 54a6. The second connecting portion 54a6 is connected to the first connecting portion 52a1 through a third via 533 on the touch insulating layer 53. The orthographic projection of the second connecting portion 54a6 on the display back panel 10 overlaps with the orthographic projection of the first connecting portion 52a1 on the display back panel 10. The area of ​​the orthographic projection of the second connecting portion 54a6 on the display back panel 10 is larger than the area of ​​the orthographic projection of the first connecting portion 52a1 on the display back panel 10.

[0137] In this example embodiment, the specific film structure of the display backplate 10 can be the same as the specific film structure in the example embodiment described above, so it will not be described again here.

[0138] Referring to Figures 9 and 11, multiple first sub-pixels 351 and multiple second sub-pixels 352 are alternately arranged along the first direction X to form a first pixel row, that is, a second sub-pixel 352 is disposed between two adjacent first sub-pixels 351, and a first sub-pixel 351 is disposed between two adjacent second sub-pixels 352. Multiple third sub-pixels 353 are arranged along the first direction X to form a second pixel row, and multiple rows of first pixel rows and multiple rows of second pixel rows are alternately arranged along the second direction Y, that is, a row of second pixel rows is disposed between two adjacent rows of first pixel rows, and a row of first pixel rows is disposed between two adjacent rows of second pixel rows. In this example embodiment, the sub-pixels 35 can be set to a circular or similar circular shape. It should be noted that the arrangement and shape of each sub-pixel 35 are only illustrative examples and do not constitute a limitation of this disclosure.

[0139] The specific film structure of the touch layer group 5 can be the same as the specific film structure in the above example embodiment, so it will not be described again here.

[0140] In this example embodiment, both the first touch functional layer 52 and the second touch functional layer 54 are made of metal. Metal has good electrical conductivity but is opaque.

[0141] The first touch function layer 52 is configured as a first grid structure 52a formed by connecting multiple first grid lines 5431. The orthographic projection of the first grid structure 52a on the display back panel 10 does not overlap with the sub-pixel 35. Specifically, the orthographic projection of the first grid structure 52a on the display back panel 10 surrounds the outer periphery of a portion of the sub-pixel 35.

[0142] The second touch function layer 54 is configured as a second grid structure 54a formed by connecting multiple second grid lines 5432. The orthographic projection of the second grid structure 54a on the display back panel 10 does not overlap with the sub-pixels 35. Specifically, the orthographic projection of the second grid structure 54a on the display back panel 10 surrounds the outer periphery of most of the sub-pixels 35.

[0143] The orthographic projection of the touch function layer group formed by the combination of the first touch function layer 52 and the second touch function layer 54 on the display back panel 10 does not overlap with the sub-pixel 35. Specifically, the orthographic projection of the touch function layer group formed by the combination of the first touch function layer 52 and the second touch function layer 54 on the display back panel 10 surrounds the outer periphery of each sub-pixel 35.

[0144] This configuration avoids the first touch function layer 52 and the second touch function layer 54 from affecting the light emission of each sub-pixel 35.

[0145] The first touch function layer 52 may include a first connection portion 52a1, and the second touch function layer 54 may include a second connection portion 54a6. The second connection portion 54a6 is connected to the first connection portion 52a1 through a third via 533 on the touch insulating layer 53, so that the first touch function layer 52 and the second touch function layer 54 are connected. Specifically, the two divided second touch electrodes 542 of the second touch function layer 54 are connected through the first touch function layer 52, thereby enabling the transmission of touch signals.

[0146] Referring to FIG12, the orthographic projection of the second connecting portion 54a6 on the display back panel 10 overlaps with the orthographic projection of the first connecting portion 52a1 on the display back panel 10. For example, the orthographic projection of the second connecting portion 54a6 on the display back panel 10 may be located within the orthographic projection of the first connecting portion 52a1 on the display back panel 10, or the orthographic projection of the first connecting portion 52a1 on the display back panel 10 may be located within the orthographic projection of the second connecting portion 54a6 on the display back panel 10; or a portion of the orthographic projection of the first connecting portion 52a1 on the display back panel 10 may overlap with a portion of the orthographic projection of the second connecting portion 54a6 on the display back panel 10. This ensures that the second connecting portion 54a6 and the first connecting portion 52a1 can be connected through the third via 533 on the touch insulating layer 53.

[0147] The area of ​​the orthographic projection of the second connecting portion 54a6 on the display back panel 10 is larger than the area of ​​the orthographic projection of the first connecting portion 52a1 on the display back panel 10. In other words, the second connecting portion 54a6 is set to be larger. On the one hand, the first connecting portion 52a1, the second connecting portion 54a6, and the third via 533 are all formed by etching, and precise alignment is required. During the fabrication process, there will inevitably be some error. If both the first connecting portion 52a1 and the second connecting portion 54a6 are set to be small, under the condition of maximum error deviation, the second connecting portion 54a6 is prone to detaching from the third via 533, causing the second connecting portion 54a6 to be unable to connect with the first connecting portion 52a1, resulting in an open circuit in the second touch electrode 542. On the other hand, by setting the second connecting portion 54a6 to be larger, even under the condition of maximum error deviation, the second connecting portion 54a6 will not detach from the third via 533, avoiding the second connecting portion 54a6 being unable to connect with the first connecting portion 52a1 and causing an open circuit in the second touch electrode 542. On the other hand, the second touch function layer 54 is provided with the main circuit of the second touch electrode 542, so its resistance is relatively large. The first touch function layer 52 is provided with the bridge part 521 of the second touch electrode 542, which has a relatively small resistance. By making the second connection part 54a6 larger, the resistance of the second touch electrode 542 can be reduced, thereby improving the signal transmission efficiency.

[0148] In some exemplary embodiments of this disclosure, as shown in FIG9, FIG11 and FIG13, the display panel has a photosensitive area GG, and a plurality of sub-photosensitive areas GG1 are provided in the photosensitive area GG. The photosensitive area GG is able to transmit light. A photosensitive device can be provided on the non-display side of the display panel, and the photosensitive device can receive light through the photosensitive area GG.

[0149] In the photosensitive area GG, the orthographic projection of the first grid structure 52a on the display back panel 10 does not overlap with the sub-pixel 35 and the sub-photosensitive area GG1; specifically, the orthographic projection of the first grid structure 52a on the display back panel 10 surrounds the outer periphery of a portion of the sub-pixel 35 and the outer periphery of a portion of the sub-photosensitive area GG1.

[0150] The orthographic projection of the second grid structure 54a on the display back panel 10 does not overlap with the sub-pixel 35 and the sub-photosensitive area GG1. Specifically, the orthographic projection of the second grid structure 54a on the display back panel 10 surrounds most of the sub-pixel 35 and most of the sub-photosensitive area GG1.

[0151] The orthographic projection of the touch function layer group formed by the combination of the first touch function layer 52 and the second touch function layer 54 on the display back panel 10 does not overlap with the sub-pixel 35 and the sub-photosensitive area GG1. Specifically, the orthographic projection of the touch function layer group formed by the combination of the first touch function layer 52 and the second touch function layer 54 on the display back panel 10 surrounds the outer periphery of each sub-pixel 35 and the outer periphery of each sub-photosensitive area GG1.

[0152] This configuration avoids the first touch function layer 52 and the second touch function layer 54 from affecting the light emission of each sub-pixel 35, and avoids the first touch function layer 52 and the second touch function layer 54 from affecting the light transmission of each sub-photosensitive area GG1, so as to ensure that the photosensitive device can receive light.

[0153] In some exemplary embodiments of this disclosure, referring to Figures 9 and 10, the first touch function layer 52 may include multiple bridging sections 521. Each bridging section 521 may include at least two bridging wires 5214, at least two first grids 5215, and at least four second grids 5216. For example, the bridging section 521 may include two bridging wires 5214, two first grids 5215, and four second grids 5216. Alternatively, the bridging section 521 may include two bridging wires 5214, four first grids 5215, and six second grids 5216. The number of bridging wires 5214, first grids 5215, and second grids 5216 can be set as needed, and will not be described in detail here.

[0154] The orthographic projection of the first grid 5215 on the display back panel 10 surrounds the sub-pixel 35, and the orthographic projection of the second grid 5216 on the display back panel 10 surrounds the sub-photosensitive area GG1. At least two second grids 5216 and at least one first grid 5215 are alternately collinearly connected to form the connection end 521a of the bridging portion 521. For example, two second grids 5216 and one first grid 5215 can be alternately collinearly connected to form the connection end 521a of the bridging portion 521. Specifically, a first grid 5215 is connected between two second grids 5216. The second grid 5216 can be set as a rectangle, and the first grid 5215 can be set as a hexagon. One edge line of the first grid 5215 is collinear with one edge line of the second grid 5216, so that the second grid 5216 and the first grid 5215 are collinearly connected. Of course, it is also possible that three second grids 5216 and two first grids 5215 are alternately and collinearly connected to form the connection end 521a of the bridging part 521, that is, a first grid 5215 is connected between two second grids 5216, and a second grid 5216 is connected between two first grids 5215. Similarly, one edge line of the first grid 5215 is collinear with one edge line of the second grid 5216, so that the second grid 5216 and the first grid 5215 are collinearly connected.

[0155] The bridging portion 521 has two connecting ends 521a. The two ends of the bridging line 5214 are connected to the second grid 5216. Specifically, the two ends of the bridging line 5214 are connected to the corner of the second grid 5216 away from the first grid 5215, and this corner is the corner close to the bridging line 5214. The bridging line 5214 is configured as a polygonal structure that cooperates with the first grid structure 52a. For example, the bridging line 5214 can be configured as a triangular polygonal structure, or it can be configured as a trapezoidal polygonal structure.

[0156] In some exemplary embodiments of this disclosure, referring to Figures 9 and 11, the second touch function layer 54 may include a plurality of first opening grids 54a1, a plurality of second opening grids 54a2, a plurality of third grids 54a3, and a plurality of fourth grids 54a4. The first opening grid 54a1 has a first opening 54a11. For example, removing at least one grid line 543 of the third grid 54a3 forms the first opening grid 54a1. The orthographic projection of the first opening grid 54a1 on the display back panel 10 surrounds a portion of the outer periphery of the sub-pixel 35, and the sub-pixel 35 is not surrounded by the first opening 54a11. The second opening grid 54a2 has a second opening 54a21. For example, removing at least one grid line 543 of the fourth grid 54a4 forms the second opening grid 54a2. The orthographic projection of the second opening grid 54a2 on the display back panel 10 surrounds a portion of the outer periphery of the sub-photosensitive area GG1, and the sub-photosensitive area GG1 is not surrounded by the second opening 54a21. The orthographic projection of the third grid 54a3 onto the display back panel 10 surrounds the sub-pixel 35, and the orthographic projection of the fourth grid 54a4 onto the display back panel 10 surrounds the sub-photosensitive area GG1.

[0157] The orthographic projection of the first open grid 54a1 onto the display back panel 10 still has the first opening 54a11, and the orthographic projection of the second open grid 54a2 onto the display back panel 10 still has the second opening 54a21. A portion of the orthographic projection of the bridging wire 5214 onto the display back panel 10 is located at the openings of the orthographic projections of the first open grid 54a1 and the second open grid 54a2 onto the display back panel 10. That is, a portion of the orthographic projection of the bridging wire 5214 onto the display back panel 10 can be located at the first opening 54a11 of the orthographic projection of the first open grid 54a1 onto the display back panel 10, and a portion of the orthographic projection of the bridging wire 5214 onto the display back panel 10 can be located at the second opening 54a21 of the orthographic projection of the second open grid 54a2 onto the display back panel 10. Alternatively, it can be described as removing the grid lines 543 on the second touch function layer 54 that are directly opposite to the bridging wire 5214 and extend in the same direction as the bridging wire 5214. This configuration reduces the overlap area between the bridging wire 5214 and the first touch electrode 541, thereby reducing the parasitic capacitance between the bridging part 521 and the first touch electrode 541 and improving the touch effect.

[0158] Referring to Figure 6, the bridging portion 521 forms a raised structure protruding from the base layer 51. After covering the touch insulating layer 53, since the touch insulating layer 53 is made of inorganic material and is relatively thin, it cannot flatten the bridging portion 521, resulting in a raised structure on the side of the touch insulating layer 53 facing away from the display back panel 10. When forming the second touch functional layer 54, it is first fully covered and then patterned to form a grid structure of the second touch functional layer 54. However, the second touch functional layer 54 at the bottom corner of the raised structure is not easily removed, forming a residual portion Rem. The residual portion Rem extends along the extension direction of the bridging portion 521, causing the residual portion Rem to electrically connect the first touch electrode 541 and the second touch electrode 542, resulting in a short circuit.

[0159] In some exemplary embodiments of this disclosure, as shown in Figures 14 and 15, the second touch function layer 54 may further include a plurality of third opening grids 54a5, each having a third opening 54a51. For example, a third opening grid 54a5 may be formed by removing one grid line 543 of a fourth grid 54a4, or by removing two grid lines 543 of a fourth grid 54a4. The orthographic projection of the third opening grid 54a5 onto the display back panel 10 surrounds a portion of the outer periphery of the sub-photosensitive area GG1.

[0160] The orthographic projection of the third opening grid 54a5 on the display back panel 10 still has the third opening 54a51. The orthographic projection of the third opening grid 54a5 on the display back panel 10 overlaps with the orthographic projection of the second grid 5216 on the display back panel 10. For example, the third opening grid 54a5 can be a grid in the second touch function layer 54 that is directly opposite to the second grid 5216.

[0161] The third opening 54a51 is located at the corner of the third opening grid 54a5 near the bridging wire 5214. This arrangement ensures that no grid line 543 is provided at the bend where the bridging wire 5214 connects to the second grid 5216. This arrangement also ensures that even if residual portions Rem are formed on both sides of the bridging portion 521 in the width direction, the residual portions Rem will bend at the bend where the bridging wire 5214 connects to the second grid 5216, thereby increasing the path length of the residual portions Rem. Furthermore, since the residual portions Rem need to bend with the bridging portion 521, they are more likely to break at the bend, further reducing the probability of the broken residual portions Rem connecting to the first touch electrode 541. This also reduces the probability of the residual portions Rem electrically connecting the first touch electrode 541 and the second touch electrode 542, which could lead to a short circuit.

[0162] In some exemplary embodiments of this disclosure, at a connection end 521a, a first connection portion 52a1 is provided at at least one corner of the first grid 5215 that is not connected to the second grid 5216; the first connection portion 52a1 is also provided at at least two corners where the first grid 5215 is connected to the second grid 5216, and is located on both sides of the second grid 5216.

[0163] For example, referring to FIG10, four first connecting parts 52a1 can be provided at a connecting end 521a. Two of the first connecting parts 52a1 are provided one-to-one at the two corners of the first grid 5215 that are not connected to the second grid 5216. The other two first connecting parts 52a1 are provided one-to-one at the two corners of the first grid 5215 and the second grid 5216. These two first connecting parts 52a1 are located one-to-one at the corners of the two second grids 5216 and are also located on both sides of the second direction Y of the second grid 5216. This ensures that the two first connecting parts 52a1 are staggered, thereby improving the uniformity of the first connecting parts 52a1 and the third via 533, avoiding the third via 533 being too concentrated, which could lead to the sidewalls of two adjacent third via 533 being easily penetrated, thus avoiding affecting the display effect.

[0164] In some exemplary embodiments of this disclosure, referring to FIG16, at a connection end 521a, a first connection portion 52a1 is provided at at least one corner of the first grid 5215 that is not connected to the second grid 5216; the first connection portion 52a1 is also provided at at least two corners where the first grid 5215 and the second grid 5216 are connected, and is located on the same side of the second grid 5216.

[0165] For example, as shown in FIG16, four first connecting parts 52a1 can be provided at a connecting end 521a. Two of the first connecting parts 52a1 are provided one-to-one at the two corners of the first grid 5215 that are not connected to the second grid 5216. The other two first connecting parts 52a1 are provided one-to-one at the two corners of the first grid 5215 and the second grid 5216. These two first connecting parts 52a1 are located one-to-one at the corners of the two second grids 5216 and are also located on the same side of the second direction Y of the second grid 5216.

[0166] Of course, in some other example embodiments of this disclosure, the first connecting part 52a1 may be located at a corner of the first grid 5215 that is not connected to the second grid 5216; if there are more first grids 5215 and second grids 5216, the first connecting part 52a1 may be set to more, which will not be described one by one here.
