[0126] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0127] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0128] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0129] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0130] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0131] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0132] After research, it was found that a traditional display panel includes a display substrate and a conductive layer arranged on the display substrate. The display substrate includes an array layer group and multiple sub-pixels. The array layer group provides corresponding driving signals to the sub-pixels. However, there will be signal interference between the conductive layer and the driving signal from the array layer group, which in turn affects the display effect of the display panel.

[0133] Based on this, the present application designs a display panel, a manufacturing method thereof, and a display device, aiming to solve the problem of poor display effect of traditional display panels.

[0134] Figure 1 1 shows a top view of a display panel in an embodiment of the present application, Figure 2 FIG2 shows a partial cross-sectional view of a display panel in an embodiment of the present application. Figure 3 A top view of the second shielding structure of an embodiment of the present application is shown (i.e., a positional relationship diagram of the second shielding structure, the third shielding structure, the metal traces, the orthographic projection of the first opening on the substrate, and the orthographic projection of the second opening on the substrate).

[0135] See also Figure 1-Figure 3 According to the first aspect of the present application, a display panel 100 provided in an embodiment of the present application includes an array substrate 110, a plurality of sub-pixels 121, a shielding structure and a conductive layer 130.

[0136] The display panel 100 includes a display area 101 and a frame area 102 located on one side of the display area 101 .

[0137] It may be that the display panel 100 has a border area 102 located on at least one side of the display area 101 along the first direction F1. For example, the display panel 100 has a border area 102 located on one side of the display area 101 along the first direction F1. For example, the border area 102 is an upper border area or a lower border area. For another example, the display panel 100 has two border areas 102, and the two border areas 102 are located on opposite sides of the display area 101 along the first direction F1. For example, the two border areas 102 are an upper border area and a lower border area, respectively. Alternatively, the display panel 100 has a border area 102 located on at least one side of the display area 101 along the second direction F2. For example, the display panel 100 has a border area 102 located on one side of the display area 101 along the second direction F2. By way of example, the border area 102 is a left border area or a right border area. For another example, the display panel 100 has two border areas 102, and the two border areas 102 are located on opposite sides of the display area 101 along the second direction F2. By way of example, the two border areas 102 are respectively a left border area and a right border area. No specific limitation is given here.

[0138] The array substrate 110 includes a stacked substrate 111 and an array layer group 112 . The plurality of sub-pixels 121 are disposed on a side of the array layer group 112 away from the substrate 111 and located in the display area 101 .

[0139] Alternatively, the array layer group 112 includes a pixel circuit (not shown) located in the display area 101 and corresponding to the sub-pixel 121 , and the sub-pixel 121 is electrically connected to the corresponding pixel circuit so that the pixel circuit provides the corresponding sub-pixel 121 with a corresponding driving signal.

[0140] The conductive layer 130 is disposed on a side of the array layer group 112 away from the substrate 11 . At least a portion of the shielding structure is disposed between the array layer group 112 and the conductive layer 130 and located in the border region 102 .

[0141] Alternatively, a portion of the shielding structure may be located between the array layer group 112 and the conductive layer 130 , and another portion of the shielding structure may be located in the array layer group 112 .

[0142] The shielding structure refers to a structure that can reduce the interference between the touch signal from the conductive layer 130 and the driving signal from the array substrate 110 . The shielding structure can be made of metal or other materials that can shield the signal.

[0143] The orthographic projection of the shielding structure on the substrate 111 covers the orthographic projection of the conductive layer 130 on the substrate 111, and at least part of the shielding structure is located between the array layer group 112 and the conductive layer 130. The shielding structure can be used to reduce the interference between the touch signal from the conductive layer 130 and the drive signal from the array substrate 110, thereby enabling the array layer group 112 to better provide the corresponding drive signal to the sub-pixel 121, thereby improving the display effect of the display panel 100.

[0144] In some embodiments, see Figure 2-Figure 4 The shielding structure includes a first shielding structure 122 disposed on a side of the array layer group 112 away from the substrate 111 , and a second shielding structure 1121 located between the first shielding structure 122 and the substrate 111 .

[0145] The second shielding structure 1121 constitutes a part of the array layer group 112 .

[0146] A first opening 1221 is formed through the first shielding structure 122 , and the orthographic projection of the second shielding structure 1121 on the substrate 111 covers the orthographic projection of the first opening 1221 on the substrate 111 .

[0147] The orthographic projection of the first opening 1221 on the substrate 111 is defined as a first projection a.

[0148] In this way, the orthographic projection of the second shielding structure 1121 on the substrate 111 covers the first projection a. On the one hand, the first shielding structure 122 and the second shielding structure 1121 can be used together to reduce interference between touch signals and drive signals. On the other hand, because the first shielding structure 122 is provided with the first opening 1221, the first shielding structure 122 can use the first opening 1221 to release water vapor generated by the evaporation process of the sub-pixels 121. This can reduce the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby improving the display quality of the display panel 100.

[0149] In some embodiments, the outer contour of the orthographic projection of the second shielding structure 1121 on the substrate 111 is located outside the orthographic projection of the first opening 1221 on the substrate 111 .

[0150] It can be understood that the orthographic projection of the second shielding structure 1121 on the substrate 111 includes a first projection portion that completely overlaps with the orthographic projection of the first opening 1221 on the substrate 111, and a second projection portion surrounding the first projection portion. In this way, the area of ​​the overlapping portion between the orthographic projection of the first shielding structure 122 on the substrate 111 and the orthographic projection of the second shielding structure 1121 on the substrate 111 is larger, and the first shielding structure 122 and the second shielding structure 1121 can be used to better reduce the interference between the touch signal and the drive signal.

[0151] In some embodiments, a dimension of the first opening 1221 in a direction parallel to the substrate 111 is greater than or equal to 3 μm.

[0152] For example, if the first opening 1221 is a square hole, the size of the first opening 1221 in a direction parallel to the substrate 111 is the size of the first opening 1221 in the length direction of the first opening 1221, the width direction of the first opening 1221, or the diagonal direction parallel to the first opening 1221. For another example, if the first opening 1221 is a circular hole, the size of the first opening 1221 in a direction parallel to the substrate 111 is the radial size of the first opening 1221.

[0153] If the size of the first opening 1221 in a direction parallel to the substrate 111 is too small, it will affect the flatness of the first shielding structure 122. Therefore, the size of the first opening 1221 in a direction parallel to the substrate 111 needs to be set to be greater than or equal to 3 μm. On the premise that the first shielding structure 122 and the second shielding structure 1121 are used to effectively reduce the interference between the touch signal and the drive signal, the larger the size of the first opening 1221 in a direction parallel to the substrate 111, the better.

[0154] In one embodiment, a dimension of the first opening 1221 in a direction parallel to the substrate 111 is greater than or equal to 3 μm and less than or equal to 20 μm.

[0155] For example, a size of the first opening 1221 in a direction parallel to the substrate 111 is 3 μm, 5 μm, 7 μm, 9 μm, 11 μm, 13 μm, 15 μm, 17 μm, or 20 μm.

[0156] In some embodiments, at least one first opening group is formed through the first shielding structure 122 , and the first opening group includes a plurality of first openings 1221 arranged at intervals.

[0157] It may be that a first opening group is provided through the first shielding structure 122; or it may be that two or more first opening groups are provided through the first shielding structure 122 and are spaced apart along the second direction F2. Without being specifically limited here, in this embodiment, a first opening group is provided through the first shielding structure 122, and the plurality of first openings 1221 of the first opening group are spaced apart along the second direction F2. The orthographic projections of the plurality of first openings 1221 of the first opening group on the substrate 111 are spaced apart along the second direction F2, that is, the plurality of first projections a corresponding to the first opening group are spaced apart along the second direction F2 (e.g., Figure 3 shown).

[0158] In this way, while the first shielding structure 122 and the second shielding structure 1121 are used together to reduce the interference between the touch signal and the driving signal, the first shielding structure 122 can use the multiple first openings 1221 to release the water vapor formed by the evaporation process of the sub-pixels 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, which is beneficial to better improve the display effect of the display panel 100.

[0159] In some embodiments, the border area 102 is located on at least one side of the display area 101 along the first direction F1, and the multiple first openings 1221 of the first opening group are arranged at intervals along the second direction F2. The first direction F1 and the second direction F2 intersect with each other and are both parallel to the substrate 111.

[0160] Optionally, the first direction F1 and the second direction F2 are perpendicular to each other. Alternatively, one of the first direction F1 and the second direction F2 is parallel to the length direction of the substrate 111, and the other of the first direction F1 and the second direction F2 is parallel to the width direction of the substrate 111. For example, the first direction F1 is parallel to the length direction of the substrate 111, and the second direction F2 is parallel to the width direction of the substrate 111.

[0161] In this way, a first opening group including a plurality of first openings 1221 can be provided on the first shielding structure 122 while minimizing the size of the second shielding structure 1121 along the first direction F1, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby helping to better improve the display effect of the display panel 100.

[0162] In some embodiments, a first opening group is formed through the first shielding structure 122. The orthographic projection of the first opening 1221 on the substrate 111 is defined as a first projection a. The first projection a has a first axis of symmetry parallel to the second direction F2. The orthographic projections of the second shielding structure 1121 on the substrate 111 are symmetrically arranged with respect to the first axis of symmetry. The second direction F2 intersects the first direction F1 and is parallel to the substrate 111. The first direction F1 is parallel to the direction from the border area 102 to the display area 101.

[0163] The first direction F1 may be parallel to the length direction of the substrate 111 or may be parallel to the width direction of the substrate 111 . In this embodiment, the first direction F1 is parallel to the length direction of the substrate 111 .

[0164] In this way, the orthographic projection of the second shielding structure 1121 on the substrate 111 can cover the first projection a, while also maximizing the size of the first projection a in the first direction F1, thereby increasing the size of the first opening 1221 in the first direction F1, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby better improving the display effect of the display panel 100.

[0165] In some embodiments, the outer contour of the positive projection of the second shielding structure 1121 on the substrate 111 has a first projection edge and a second projection edge arranged opposite to each other along the first direction F1. Along the first direction F1, the spacing between the first projection edge and the first projection a is equal to the spacing between the second projection edge and the first projection a, and both are greater than the first preset value.

[0166] The second shielding structure 1121 has a first edge 11211 and a second edge 11212 arranged opposite to each other along the first direction F1. The orthographic projection of the first edge 11211 on the substrate 111 coincides with the first projection edge, and the orthographic projection of the second edge 11212 on the substrate 111 coincides with the second projection edge. Then, along the first direction F1, the distance between the orthographic projection of the first edge 11211 on the substrate 111 and the first projection a is equal to the distance between the orthographic projection of the second edge 11212 on the substrate 111 and the first projection a, and both are greater than the first preset value.

[0167] See also Figure 3 , the distance between the orthographic projection of the first edge 11211 on the substrate 111 and the first projection a, and the distance between the orthographic projection of the second edge 11212 on the substrate 111 and the first projection a are both L1, then L1 is greater than the first preset value.

[0168] In this way, L1 is greater than the first preset value, so that the orthographic projection of the first shielding structure 122 on the substrate 111 and the second shielding structure 1121 on the substrate 111 have more overlapping parts. In this way, the first shielding structure 122 and the second shielding structure 1121 can be well utilized to reduce the interference between the touch signal and the drive signal.

[0169] In one embodiment, the first preset value is greater than or equal to 5 μm.

[0170] For example, the first preset value is 5 μm, 6 μm, 7 μm, or greater than 7 μm.

[0171] By setting the first preset value within an appropriate range, the first shielding structure 122 and the second shielding structure 1121 can be effectively utilized to reduce the interference between the touch signal and the drive signal. At the same time, it is also necessary to make the size of the first opening 1221 in the first direction F1 sufficiently large, which is beneficial to reduce the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby improving the display effect of the display panel 100.

[0172] In some embodiments, the border region 102 is located on at least one side of the display region 101 along the first direction F1. The array layer assembly 112 includes a plurality of metal traces 1122 located in the border region 102 and spaced apart along the first direction F1. The metal traces 1122 and the second shielding structure 1121 are disposed on the same layer and are insulated from each other. Along the first direction F1, the second shielding structure 1121 is located between two metal traces 1122.

[0173] Optionally, along the first direction F1 , the second shielding structure 1121 is located between two adjacent metal traces 1122 .

[0174] A second shielding structure 1121 is provided in the space between the two metal traces 1122. This allows the first and second shielding structures 1122 to work together to reduce interference between touch signals and drive signals. Furthermore, the first shielding structure 122, provided with the first opening 1221, reduces the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby improving the display quality of the display panel 100. Furthermore, this does not affect the external connection of the metal traces 1122 located in the border area 102. For example, the corresponding drive signals can be transmitted to the sub-pixels 121 located in the display area 101 via the externally connected metal traces 1122. Furthermore, the second shielding structure 1121 and the metal traces 1122 can be formed in the same manufacturing process, thereby reducing the manufacturing process time of the display panel 100 and improving the manufacturing efficiency of the display panel 100.

[0175] Optionally, the metal wiring 1122 may be a scanning signal line, and the metal wiring 1122 is used to provide a corresponding scanning signal to the sub-pixel 121 .

[0176] Optionally, the metal trace 1122 includes a first metal layer, a second metal layer, and a third metal layer that are stacked, and the activity of the first metal layer and the third metal layer is lower than that of the second metal layer.

[0177] For example, the first metal layer and the third metal layer are made of titanium, and the second metal layer is made of aluminum.

[0178] The first metal layer and the third metal layer can be used to protect the more active second metal layer, and the reliability of the metal trace 1122 can also be improved by stacking the first metal layer, the second metal layer, and the third metal layer.

[0179] Optionally, the orthographic projection of the first shielding structure 122 on the substrate 111 covers the orthographic projections of all metal traces 1122 on the substrate 111 .

[0180] In this way, the first shielding structure 122 can be effectively utilized to reduce the interference between the driving signal from the metal trace 1122 and the touch signal from the conductive layer 130 .

[0181] In some embodiments, the array layer assembly 112 includes a third shielding structure 1123 spaced apart from the second shielding structure 1121 along a first direction F1. The third shielding structure 1123 is disposed on the same layer as the second shielding structure 1121. The first direction F1 is parallel to the border area 102 and points toward the display area 101. A second opening 1222 is defined through the first shielding structure 122. The orthographic projection of the third shielding structure 1123 on the substrate 111 covers the orthographic projection of the second opening 1222 on the substrate 111.

[0182] The orthographic projection of the second opening 1222 on the substrate 111 is defined as a second projection b.

[0183] The first direction F1 may be parallel to the length direction of the substrate 111 or may be parallel to the width direction of the substrate 111 . In this embodiment, the first direction F1 is parallel to the length direction of the substrate 111 .

[0184] In this embodiment, the second shielding structure 1121 , the metal traces 1122 and the third shielding structure 1123 are disposed in the same layer and arranged at intervals along the first direction F1 .

[0185] In this manner, on the one hand, the first shielding structure 122, the second shielding structure 1121, and the third shielding structure 1123 can be used together to reduce interference between touch signals and drive signals. On the other hand, because the first shielding structure 122 is provided with the first opening 1221 and the second opening 1222, the first shielding structure 122 can use the first opening 1221 and the second opening 1222 to release moisture generated during the evaporation process of the sub-pixels 121. This can further reduce the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby further improving the display quality of the display panel 100. Furthermore, the second shielding structure 1121 and the third shielding structure 1123 can be formed in the same manufacturing process, which can reduce the manufacturing process time of the display panel 100 and thereby improve the manufacturing efficiency of the display panel 100.

[0186] In some embodiments, the outer contour of the orthographic projection of the third shielding structure 1123 on the substrate 111 is located outside the orthographic projection of the second opening 1222 on the substrate 111 .

[0187] It can be understood that the orthographic projection of the third shielding structure 1123 on the substrate 111 includes a third projection portion that completely overlaps with the second projection b, and a fourth projection portion surrounding the third projection portion. In this way, the area of ​​the overlapping portion between the orthographic projection of the first shielding structure 122 on the substrate 111 and the orthographic projection of the third shielding structure 1123 on the substrate 111 is larger, and the third shielding structure 1123 and the first shielding structure 122 can be used to better reduce the interference between the touch signal and the drive signal.

[0188] In some embodiments, along the first direction F1 , the interval between adjacent first openings 1221 and second openings 1222 is less than a second preset value.

[0189] See also Figure 4 , along the first direction F1, the distance between the adjacent first openings 1221 and the second openings 1222 is L2, then, L2 is less than the second preset value.

[0190] If the spacing between adjacent first openings 1221 and second openings 1222 is too large, the size of the portion of the first shielding structure 122 used to open the first opening 1221 along the first direction F1 will be too small, and the size of the portion of the first shielding structure 122 used to open the second opening 1222 along the first direction F1 will be too small, which will affect the size of the first opening 1221 and the second opening 1222 along the first direction F1. Therefore, it is necessary to set the spacing between adjacent first openings 1221 and second openings 1222 to be less than the second preset value, so that the spacing between adjacent first openings 1221 and second openings 1222 is smaller, which is beneficial to increase the size of the first opening 1221 and the second opening 1222 along the first direction F1, and further reduce the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, which is more beneficial to improving the display effect of the display panel 100.

[0191] Optionally, the second preset value is 70 μm-90 μm.

[0192] The second preset value may be 70 μm, 80 μm or 90 μm.

[0193] Setting the second preset value within a suitable range is beneficial to increasing the sizes of the first opening 1221 and the second opening 1222 along the first direction F1 , thereby further improving the display effect of the display panel 100 .

[0194] In some embodiments, a second opening group corresponding to the third shielding structure 1123 is formed through the first shielding structure 122 , and the second opening group includes a plurality of second openings 1222 arranged at intervals.

[0195] It can be understood that the outer contour of the orthographic projection of the third shielding structure 1123 on the substrate 111 is located at the periphery of the orthographic projections of all the second openings 1222 of the corresponding second opening group on the substrate 111 .

[0196] In this way, while the first shielding structure 122 and the third shielding structure 1123 are used together to reduce the interference between the touch signal and the driving signal, the first shielding structure 122 can use the multiple second openings 1222 to release the water vapor formed by the evaporation process of the factor pixels 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, which is beneficial to improving the display effect of the display panel 100.

[0197] In some embodiments, the dimension of the third shielding structure 1123 along the first direction F1 is greater than the dimension of the second shielding structure 1121 along the first direction F1, and the number of second openings 1222 corresponding to the third shielding structure 1123 is greater than the number of first openings 1221 corresponding to the second shielding structure 1121.

[0198] The size of the third shielding structure 1123 along the first direction F1 is set to be larger than the size of the second shielding structure 1121 along the first direction F1, which is more conducive to arranging the second shielding structure 1121 between the two metal traces 1122, so as to better utilize the space between the two metal traces 1122. Considering the factor that "the size of the third shielding structure 1123 along the first direction F1 is larger than the size of the second shielding structure 1121 along the first direction F1", the number of the second openings 1222 corresponding to the third shielding structure 1123 is set to be larger than the number of the first openings corresponding to the second shielding structure 1121. The number of 1221 is conducive to the reasonable layout of the number of first openings 1221 according to the size of the second shielding structure 1121 along the first direction F1, and is also conducive to the reasonable layout of the number of second openings 1222 according to the size of the third shielding structure 1123 along the first direction F1, thereby achieving the goal of utilizing the first shielding structure 122, the second shielding structure 1121 and the third shielding structure 1123 to jointly reduce the interference between the touch signal and the drive signal, while better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, which is conducive to improving the display effect of the display panel 100.

[0199] In some embodiments, the plurality of second openings 1222 of the second opening group are arranged at intervals along the second direction F2 ; the first direction F1 and the second direction F2 intersect with each other and are both parallel to the substrate 111 .

[0200] In this way, while minimizing the size of the third shielding structure 1123 along the first direction F1, a second opening group including a plurality of second openings 1222 can be provided on the first shielding structure 122, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby helping to better improve the display effect of the display panel 100.

[0201] In some embodiments, the display panel 100 further includes at least two third shielding structures 1123 located on both sides of the second shielding structure 1121 along the first direction F1. The first shielding structure 122 is penetrated by a plurality of second opening groups spaced apart along the first direction F1. The outer contour of the orthographic projection of the third shielding structure 1123 on the substrate 111 is located at the periphery of the orthographic projection of all second openings 1222 of the corresponding second opening group on the substrate 111.

[0202] Alternatively, the second opening group may correspond to the third shielding structure 1123 in a one-to-one manner, or the third shielding structure 1123 may correspond to the second opening group in a one-to-many manner.

[0203] In this embodiment, the second shielding structure 1121 , the metal traces 1122 and the third shielding structure 1123 are arranged in the same layer, and at least two third shielding structures 1123 are located on both sides of the overall structure consisting of the plurality of metal traces 1122 and the second shielding structure 1121 along the first direction F1 .

[0204] In this way, more groups of second opening groups can be set on the first shielding structure 122. The first shielding structure 122 can use more second openings 1222 to release water vapor formed by the evaporation process of the factor pixels 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, which is beneficial to improving the display effect of the display panel 100.

[0205] In some embodiments, the orthographic projections of the second openings 1222 of two or more adjacent second opening groups along the first direction F1 on the substrate 111 are located within the outer contour of the orthographic projection of the corresponding third shielding structure 1123 on the substrate 111 .

[0206] The two or more adjacent second opening groups along the first direction F1 are arranged corresponding to the same third shielding structure 1123, which facilitates the reasonable layout of the sizes and positions of the corresponding two or more second opening groups in the first direction F1 according to the position of the third shielding structure 1123 in the first direction F1, and is conducive to maximizing the design of the second openings 1222 of the second opening group, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, and thus helping to improve the display effect of the display panel 100.

[0207] In some embodiments, the second openings 1222 of two adjacent second opening groups are staggered along the second direction F2.

[0208] In this way, when the size of the first shielding structure 122 along the second direction F2 is constant, the second openings 1222 of two adjacent groups of second openings are staggered along the second direction F2, which is conducive to designing more second openings 1222, and further helps to better reduce the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, and further helps to better improve the display effect of the display panel 100.

[0209] In some embodiments, a third opening 11231 is defined through the third shielding structure 1123 , and the orthographic projection of the first shielding structure 122 on the substrate 111 covers the orthographic projection of the third opening 11231 on the substrate 111 .

[0210] On the one hand, the first shielding structure 122, the second shielding structure 1121 and the third shielding structure 1123 can be used together to reduce the interference between the touch signal and the drive signal. On the other hand, since the third shielding structure 1123 is penetrated by the third opening 11231, the third shielding structure 1123 can use the third opening 11231 to release water vapor, thereby reducing the probability of the third shielding structure 1123 becoming uneven or peeling off from the substrate 111, which is beneficial to improving the display effect of the display panel 100.

[0211] Optionally, the outer contour of the orthographic projection of the first shielding structure 122 on the substrate 111 is located at the periphery of the orthographic projection of the third opening 11231 on the substrate 111 .

[0212] In this way, the orthographic projection of the first shielding structure 122 on the substrate 111 and the orthographic projection of the third shielding structure 1123 on the substrate 111 have more overlapping parts, which is conducive to better utilizing the first shielding structure 122, the second shielding structure 1121 and the third shielding structure 1123 to jointly reduce the interference between the touch signal and the drive signal.

[0213] In some embodiments, the orthographic projection of the third opening 11231 on the substrate 111 does not overlap with the orthographic projection of the second opening 1222 on the substrate 111. In other words, the orthographic projection of the third opening 11231 on the substrate 111 does not overlap with the second projection b. Specifically, the orthographic projection of the third opening 11231 on the substrate 111 is spaced apart from the orthographic projection of the second opening 1222 on the substrate 111. In other words, the orthographic projection of the third opening 11231 on the substrate 111 is spaced apart from the second projection b.

[0214] On the one hand, the first shielding structure 122, the second shielding structure 1121 and the third shielding structure 1123 can be used together to reduce the interference between the touch signal and the driving signal. On the other hand, the first shielding structure 122 can use the first opening 1221 and the second opening 1222 to release water vapor formed by the evaporation process of the factor pixel 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110. The third shielding structure 1123 can use the third opening 11231 to release water vapor, thereby reducing the probability of the third shielding structure 1123 becoming uneven or peeling off from the substrate 111, which is beneficial to improving the display effect of the display panel 100.

[0215] In some embodiments, the third shielding structure 1123 is penetrated by a plurality of third openings 11231 arranged at intervals, and the outer contour of the orthographic projection of the first shielding structure 122 on the substrate 111 is located outside the orthographic projection of all third openings 11231 on the substrate 111.

[0216] Optionally, multiple third openings 11231 are arranged to form multiple groups of third opening groups z1 spaced apart along the first direction F1, each group of third opening groups z1 includes multiple third openings 11231 spaced apart along the second direction F2, the first direction F1 and the second direction F2 intersect with each other and are both parallel to the substrate 111.

[0217] In this way, on the one hand, the first shielding structure 122, the second shielding structure 1121 and the third shielding structure 1123 can be used together to reduce the interference between the touch signal and the driving signal. On the other hand, the first shielding structure 122 can use the first opening 1221 and the second opening 1222 to release the water vapor formed by the evaporation process of the factor pixel 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110. The third shielding structure 1123 can use multiple third openings 11231 to release water vapor, thereby better reducing the probability of the third shielding structure 1123 becoming uneven or peeling off from the substrate 111, thereby helping to improve the display effect of the display panel 100.

[0218] In some embodiments, the third opening group z1 corresponds one-to-one to the above-mentioned second opening group, and the orthographic projections of the multiple third openings 11231 of the third opening group z1 on the substrate 111 and the orthographic projections of the corresponding multiple second openings 1222 of the second opening group on the substrate 111 are alternately arranged along the second direction F2.

[0219] While facilitating the layout of the multiple second openings 1222 and the multiple third openings 11231, the first shielding structure 122 can also utilize the first openings 1221 and the multiple second openings 1222 to better release the water vapor formed by the evaporation process of the factor pixels 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110. The third shielding structure 1123 can utilize the multiple third openings 11231 to release water vapor, thereby better reducing the probability of the third shielding structure 1123 becoming uneven or peeling off from the substrate 111, thereby helping to improve the display effect of the display panel 100.

[0220] In some embodiments, a fourth opening 11213 is defined through the second shielding structure 1121 , and the orthographic projection of the first shielding structure 122 on the substrate 111 covers the orthographic projection of the fourth opening 11213 on the substrate 111 .

[0221] On the one hand, the first shielding structure 122 and the second shielding structure 1121 can be used together to reduce the interference between the touch signal and the drive signal. On the other hand, since the fourth opening 11213 is provided through the second shielding structure 1121, the second shielding structure 1121 can use the fourth opening 11213 to release water vapor, thereby reducing the probability of the second shielding structure 1121 becoming uneven or peeling off from the substrate 111, which is beneficial to improving the display effect of the display panel 100.

[0222] In some embodiments, the outer contour of the orthographic projection of the first shielding structure 122 on the substrate 111 is located outside the orthographic projection of the fourth opening 11213 on the substrate 111 .

[0223] In this way, the orthographic projection of the first shielding structure 122 on the substrate 111 and the orthographic projection of the second shielding structure 1121 on the substrate 111 have more overlapping parts, which is conducive to better utilizing the first shielding structure 122 and the second shielding structure 1121 to jointly reduce the interference between the touch signal and the drive signal.

[0224] In some embodiments, the orthographic projection of the fourth opening 11213 on the substrate 111 does not overlap with the orthographic projection of the first opening 1221 on the substrate 111. In other words, the orthographic projection of the fourth opening 11213 on the substrate 111 does not overlap with the first projection a. Specifically, the orthographic projection of the fourth opening 11213 on the substrate 111 is spaced apart from the orthographic projection of the first opening 1221 on the substrate 111. In other words, the orthographic projection of the fourth opening 11213 on the substrate 111 is spaced apart from the first projection a.

[0225] On the one hand, the first shielding structure 122 and the second shielding structure 1121 can be used together to reduce the interference between the touch signal and the driving signal. On the other hand, the first shielding structure 122 can use the first opening 1221 to release water vapor formed by the evaporation process of the factor pixel 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110. The second shielding structure 1121 can use the fourth opening 11213 to release water vapor, thereby reducing the probability of the second shielding structure 1121 becoming uneven or peeling off from the substrate 111, which is beneficial to improving the display effect of the display panel 100.

[0226] In some embodiments, a plurality of fourth openings 11213 arranged at intervals are formed through the second shielding structure 1121 , and an outer contour of an orthographic projection of the first shielding structure 122 on the substrate 111 is located outside the orthographic projections of all the fourth openings 11213 on the substrate 111 ;

[0227] Optionally, multiple fourth openings 11213 are arranged to form at least one fourth opening group z2, each fourth opening group z2 includes multiple fourth openings 11213 arranged at intervals along the second direction F2, the first direction F1 and the second direction F2 intersect with each other and are both parallel to the substrate 111.

[0228] In this way, on the one hand, the first shielding structure 122 and the second shielding structure 1121 can be used together to reduce the interference between the touch signal and the driving signal. On the other hand, the first shielding structure 122 can use the first opening 1221 to release water vapor formed by the evaporation process of the factor pixel 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110. The second shielding structure 1121 can use multiple fourth openings 11213 to release water vapor, thereby better reducing the probability of the second shielding structure 1121 becoming uneven or peeling off from the substrate 111, which is beneficial to improving the display effect of the display panel 100.

[0229] In some embodiments, the fourth hole group z2 corresponds one-to-one with the first hole group described above. The orthographic projections of the plurality of fourth holes 11213 of the fourth hole group z2 on the substrate 111 are arranged alternately with the orthographic projections of the plurality of first holes 1221 of the corresponding first hole group on the substrate 111 along the second direction F2. For example, the fourth hole group z2 and the first hole group each have one group.

[0230] While facilitating the layout of the plurality of fourth openings 11213 and the plurality of first openings 1221, the first shielding structure 122 can also utilize the plurality of first openings 1221 to better release moisture generated during the evaporation process of the sub-pixels 121, thereby further reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110. The second shielding structure 1121 can utilize the plurality of fourth openings 11213 to release moisture, thereby further reducing the probability of the second shielding structure 1121 becoming uneven or peeling off from the substrate 111, thereby facilitating improved display quality of the display panel 100. In some embodiments, the first shielding structure 122 extends from a side close to the display area 101 toward a side away from the display area 101.

[0231] It can be understood that the first shielding structure 122 is a full-surface structure, and the first shielding structure 122 , the second shielding structure 1121 and the third shielding structure 1123 can be better utilized to reduce interference between the touch signal and the driving signal.

[0232] In some embodiments, a side of the first shielding structure 122 away from the display area 101 extends to cover the third shielding structure 1123 further away from the display area 101 .

[0233] In other words, the side of the first shielding structure 122 away from the display area 101 overlaps with the third shielding structure 1123, which is further away from the display area 101, facilitating connection of an external driver chip to the third shielding structure 1123, which is further away from the display area 101. This allows the driver chip to provide shielding signals to both the third shielding structure 1123 and the first shielding structure 122, and the electrically connected third shielding structure 1123 and first shielding structure 122 can further reduce interference between touch signals and drive signals.

[0234] Optionally, the shielding signal has the same potential as the low-level signal VSS.

[0235] In some embodiments, a side of the first shielding structure 122 close to the display area 101 extends to cover the third shielding structure 1123 closer to the display area 101 .

[0236] That is, the side of the first shielding structure 122 close to the display area 101 overlaps with the third shielding structure 1123 closer to the display area 101. In this way, the electrically connected third shielding structure 1123 and the first shielding structure 122 can be used to better reduce the interference between the touch signal and the driving signal.

[0237] In some other embodiments, the side of the first shielding structure 122 away from the display area 101 extends to cover the third shielding structure 1123 further away from the display area 101, and the side of the first shielding structure 122 close to the display area 101 extends to cover the third shielding structure 1123 closer to the display area 101.

[0238] In this way, the driver chip can provide shielding signals to the third shielding structure 1123 and the first shielding structure 122, and the electrically connected third shielding structure 1123 and the first shielding structure 122 can be used to better reduce interference between the touch signal and the driving signal. In some embodiments, the first shielding structure 122 is electrically connected to the second shielding structure 1121.

[0239] Electrically connecting the first shielding structure 122 and the second shielding structure 1121 can form a better shielding effect between the first shielding structure 122 and the second shielding structure 1121, so as to better utilize the combined structure of the first shielding structure 122 and the second shielding structure 1121 to reduce interference between touch signals and driving signals.

[0240] Specifically, the display panel 100 further includes a driving chip, which is electrically connected to the first shielding structure 122 and can provide corresponding shielding signals to the first shielding structure 122 and the second shielding structure 1121 to reduce interference between the touch signal and the driving signal.

[0241] In some embodiments, the display panel 100 further includes a flat layer 113 disposed on a side of the array layer group 112 away from the substrate 111, the flat layer 113 covers the second shielding structure 1121, the first shielding structure 122 is disposed on a side of the flat layer 113 away from the array layer group 112, a via connection structure 114 is provided on the flat layer 113, and the first shielding structure 122 and the second shielding structure 1121 are electrically connected through the via connection structure 114.

[0242] In this embodiment, the planar layer 113 also covers the third shielding structure 1123 and the metal trace 1122 .

[0243] The first shielding structure 122 and the second shielding structure 1121 are electrically connected through the via connection structure 114. The first shielding structure 122 and the second shielding structure 1121 can be well utilized to reduce the interference between the touch signal and the driving signal, so that the first shielding structure 122 and the second shielding structure 1121 form a combined shielding effect.

[0244] In some embodiments, a plurality of via connection structures 114 are provided on the flat layer 113, and the plurality of via connection structures 114 are arranged at intervals around the same adjacent first opening 1221 (which can be combined with Figure 5 to understand).

[0245] The plurality of via connection structures 114 can be used to improve the reliability of the electrical connection between the first shielding structure 122 and the second shielding structure 1121 , so as to better utilize the first shielding structure 122 and the second shielding structure 1121 to reduce interference between the touch signal and the driving signal.

[0246] Optionally, a plurality of via connection structures 114 are arranged at equal intervals around adjacent first openings 1221 .

[0247] The first shielding structure 122 and the second shielding structure 1121 can be used to reduce the interference between the touch signal and the drive signal. At the same time, the multiple via connection structures 114 arranged at equal intervals can also improve the flatness of the first shielding structure 122, thereby effectively reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110.

[0248] In some embodiments, the first shielding structure 122 is electrically connected to the third shielding structure 1123 .

[0249] Specifically, see Figure 2 and Figure 6 The first shielding structure 122 is electrically connected to the driver chip via a third shielding structure 1123 located along the first direction F1 on the side of the second shielding structure 1121 away from the display area 101. Two third shielding structures 1123 are provided: the third shielding structure 1123 located farther from the display area 101 along the first direction F1 overlaps the side of the first shielding structure 122 located away from the display area 101 along the first direction F1. The third shielding structure 1123 located farther from the display area 101 along the first direction F1 is electrically connected to the driver chip at the binding area 103 along the side away from the display area 101 along the first direction F1. The third shielding structure 1123 located closer to the display area 101 along the first direction F1 overlaps the side of the first shielding structure 122 located closer to the display area 101 along the first direction F1.

[0250] In this way, the driving chip can be used to provide a shielding signal to the third shielding structure 1123, the first shielding structure 122 and the second shielding structure 1121 electrically connected to the first shielding structure 122, and the electrically connected third shielding structure 1123, the first shielding structure 122 and the second shielding structure 1121 can be used to better reduce the interference between the touch signal and the driving signal.

[0251] In some embodiments, the conductive layer 130 includes multiple first touch electrodes 131 located in the border area 102, and the orthographic projections of the multiple first touch electrodes 131 on the substrate 111 are located within the range of the outer contours of the orthographic projections of the first shielding structure 122 and the second shielding structure 1121 on the substrate 111.

[0252] Since the orthographic projections of the plurality of first touch electrodes 131 on the substrate 111 are located within the outer contours of the orthographic projections of the first shielding structure 122 and the second shielding structure 1121 on the substrate 111, the first shielding structure 122 and the second shielding structure 1121 can be well utilized to reduce interference between the touch signals from the first touch electrodes 131 and the driving signals below the first shielding structure 122.

[0253] In this embodiment, the conductive layer 130 further includes a plurality of second touch electrodes 132 located in the display area 101. The first touch electrodes 131 and the second touch electrodes 132 are disposed in the same layer and are spaced apart along the first direction F1.

[0254] In this way, the first touch electrodes 131 and the second touch electrodes 132 can be formed in the same manufacturing process, which can reduce the manufacturing process time of the display panel 100 and further improve the manufacturing efficiency of the display panel 100 .

[0255] In some embodiments, the sub-pixel 121 includes a first electrode 1211 , a light-emitting layer 1212 , and a second electrode 1213 that are stacked. The first electrode 1211 and the first shielding structure 122 are disposed in the same layer.

[0256] In this way, the first electrode 1211 and the first shielding structure 122 can be formed in the same manufacturing process, which can reduce the manufacturing process time of the display panel 100 and further improve the manufacturing efficiency of the display panel 100 .

[0257] In some embodiments, the display panel 100 also includes a pixel definition layer 140 covering the first electrode 1211 and the first shielding structure 122. The pixel definition layer 140 is provided with a pixel opening 141 that at least partially exposes the first electrode 1211 and is located in the display area 101, and a fifth opening 142 is located in the border area 102. The light-emitting layer 1212 and the second electrode 1213 of the sub-pixel 121 are arranged in the corresponding pixel opening 141. The fifth opening 142 corresponds to the first opening 1221, and the fifth opening 142 and the corresponding first opening 1221 are connected to each other.

[0258] The fifth openings 142 may correspond to the first openings 1221 in a one-to-one manner, or the fifth openings 142 may correspond to the first openings 1221 in a one-to-many manner.

[0259] The fifth opening 142 on the pixel definition layer 140 can be used to release water vapor generated by the evaporation process of the sub-pixels 121 , thereby reducing the probability of unevenness or cracking of the pixel definition layer 140 , thereby improving the display effect of the display panel 100 .

[0260] In some embodiments, the first opening 1221 at least partially overlaps with the corresponding fifth opening 142 .

[0261] It is convenient to adjust the mask corresponding to the fifth opening 142 according to the mask corresponding to the first opening 1221 , thereby improving the convenience of opening the fifth opening 142 .

[0262] In some embodiments, the pixel definition layer 140 includes a first portion 143 extending into the corresponding first opening 1221 . The first portion 143 defines a fifth opening 142 corresponding to the first opening 1221 , and the first portion 143 completely covers the inner wall of the corresponding first opening 1221 .

[0263] The first portion 143 can be well utilized to protect the first shielding structure 122 where the first opening 1221 is provided, thereby improving the reliability of the first shielding structure 122 in reducing interference between the touch signal and the driving signal.

[0264] In some embodiments, the pixel definition layer 140 defines a sixth opening 144 located in the border region 102 . The sixth opening 144 corresponds to the second opening 1222 , and the sixth opening 144 and the corresponding second opening 1222 are connected to each other.

[0265] The sixth openings 144 may correspond to the second openings 1222 in a one-to-one manner, or the sixth openings 144 may correspond to the second openings 1222 in a one-to-many manner. In this embodiment, the sixth openings 144 correspond to the second openings 1222 in a one-to-one manner.

[0266] The sixth opening 144 on the pixel definition layer 140 can be used to release water vapor generated by the evaporation process of the sub-pixels 121 , thereby reducing the probability of unevenness or cracking of the pixel definition layer 140 , thereby improving the display effect of the display panel 100 .

[0267] In some embodiments, the second opening 1222 at least partially overlaps with the corresponding sixth opening 144 .

[0268] It is convenient to adjust the mask corresponding to the sixth opening 144 according to the mask corresponding to the second opening 1222 , thereby improving the convenience of opening the sixth opening 144 .

[0269] In some embodiments, the pixel definition layer 140 includes a second portion 145 extending into the corresponding second opening 1222 . The second portion 145 defines a sixth opening 144 corresponding to the second opening 1222 , and the second portion 145 completely covers the inner wall of the corresponding second opening 1222 .

[0270] The second portion 145 can be well utilized to protect the first shielding structure 122 where the second opening 1222 is provided, thereby improving the reliability of the first shielding structure 122 in reducing interference between the touch signal and the driving signal.

[0271] The display panel 100 further includes a peripheral isolation region located on a side of the border region 102 away from the display region 101. The display panel 100 further includes a peripheral dam 170 located in the peripheral isolation region. The pixel definition layer 140 further covers the peripheral dam 170. Specifically, the peripheral isolation region is located along the first direction F1 on a side of the border region 102 away from the display region 101.

[0272] The peripheral dam 170 may be used to protect the first shielding structure 122 and other structures in the border area 102 , thereby improving the reliability of the display panel 100 .

[0273] In some embodiments, the display panel 100 further includes an encapsulation layer 150 , which is disposed on the array substrate 110 and covers the plurality of sub-pixels 121 and the first shielding structure 122 ; the conductive layer 130 is disposed on a side of the encapsulation layer 150 away from the array substrate 110 .

[0274] The encapsulation layer 150 can be used to prevent water vapor, oxygen, etc. from entering the sub-pixels 121 and the first shielding structure 122 , which is beneficial for improving the reliability of the display panel 100 .

[0275] In some embodiments, see Figure 2 and Figure 7 The display panel 100 further includes a pixel definition layer 140 and a partition structure 160 disposed on the array substrate 110. The pixel definition layer 140 defines pixel openings 141 corresponding to the sub-pixels 121. The partition structure 160 defines a plurality of partition openings 1601 communicating with the corresponding pixel openings 141. At least a portion of the sub-pixels 121 is disposed within the corresponding pixel openings 141. The pixel definition layer 140 covers the first shielding structure 122. The encapsulation layer 150 covers the partition structure 160, the pixel definition layer 140, and the plurality of sub-pixels 121. The encapsulation layer 150 includes a first encapsulation layer, which includes a plurality of sub-encapsulation portions 151. The sub-encapsulation portions 151 are disposed one-to-one within the partition openings 1601, and the sub-encapsulation portions 151 completely cover the corresponding sub-pixels 121.

[0276] Among them, the partition structure 160 is used to separate the pixel materials of adjacent sub-pixels 121 so as to separate the pixel materials of the sub-pixels 121 during evaporation. In this way, after the partition structure 160 for separating adjacent sub-pixels 121 is formed on the array substrate 110, the sub-pixels 121 can be formed by evaporation. In this process, the expensive fine metal mask plate (FMM) can be discarded, thereby reducing the production cost of the display panel 100.

[0277] The partition structure 160 can be a one-piece structure or a layered structure. The partition structure 160 includes but is not limited to the following: Figure 4 In the structure shown, the partition structure 160 may also be an inverted trapezoid, an I-shape, or other shapes, as long as it can separate adjacent sub-pixels 121 .

[0278] In this way, the sub-packaging portion 151 can be used to prevent water vapor and oxygen from entering the corresponding sub-pixel 121 , thereby forming an independent package for the sub-pixel 121 , which is beneficial for improving the reliability of the display panel 100 .

[0279] In some embodiments, the encapsulation layer 150 also includes a second encapsulation layer 152, the second encapsulation layer 152 includes a first encapsulation portion 1521 located in the display area 101, and a second encapsulation portion 1522 located in the border area 102, the first encapsulation portion 1521 covers the partition structure 160 and the multiple sub-encapsulation portions 151, and the second encapsulation portion 1522 covers the portion of the pixel definition layer 140 covered on the first shielding structure 122.

[0280] The first packaging part 1521 and the sub-packaging part 151 can be used to form a double packaging for the sub-pixel 121, thereby improving the water vapor barrier capability and further improving the reliability of the display panel 100. The second packaging part 1522 can also be used to protect the first shielding structure 122.

[0281] In some embodiments, the encapsulation layer 150 further includes a third encapsulation layer 153 , and the third encapsulation layer 153 covers the second encapsulation layer 152 .

[0282] Optionally, the second encapsulation layer 152 may be made of an organic material, and the third encapsulation layer 153 may be made of an inorganic material.

[0283] The sub-encapsulation portion 151 , the second encapsulation layer 152 and the third encapsulation layer 153 can be used to better block water vapor and oxygen from entering the sub-pixel 121 and the first shielding structure 122 , thereby improving the reliability of the display panel 100 .

[0284] In some embodiments, the partition structure 160 includes an isolator 161 and a blocking portion 162 stacked in a direction away from the array substrate 110 ; the blocking portion 162 extends toward the partition opening 1601 to protrude from the wall 1611 of the isolator 161 .

[0285] It can be understood that the orthographic projection outer contour of the blocking portion 162 on the substrate 111 is located outside the orthographic projection outer contour of the corresponding isolating body 161 on the substrate 111 .

[0286] Specifically, the width of the bottom surface of the blocking portion 162 is greater than the width of the top surface of the isolator 161 , and the width is the size of the orthographic projection of the partition structure 160 on the substrate 111 along the first direction F1 or the second direction F2 .

[0287] In this way, when manufacturing the display panel 100 , the partition structure 160 can achieve a better partitioning effect on the pixel material corresponding to the sub-pixel 121 and the encapsulation material corresponding to the sub-encapsulation portion 151 .

[0288] According to a second aspect of the present application, a display panel 100 has a display area 101 and a border area 102 located on one side of the display area 101. The display panel 100 includes an array substrate 110, a plurality of sub-pixels 121, a first shielding structure 122, and a conductive layer 130. The array substrate 110 includes a stacked substrate 111 and an array layer group 112. The array layer group 112 includes a second shielding structure 1121 and a third shielding structure 1123 located in the border area 102 and spaced apart from each other. The first shielding structure 122 is provided with a first opening 1221 and a second opening 1222. The orthographic projection of the second shielding structure 1121 on the substrate 111 covers the orthographic projection of the first opening 1221 on the substrate 111. The orthographic projection of the third shielding structure 1123 on the substrate 111 covers the orthographic projection of the second opening 1222 on the substrate 111.

[0289] In this way, the orthographic projection of the second shielding structure 1121 on the substrate 111 covers the first projection a, and the orthographic projection of the third shielding structure 1123 on the substrate 111 covers the first projection b. On the one hand, the first shielding structure 122, the second shielding structure 1121, and the third shielding structure 1123 can be used together to reduce interference between touch signals and drive signals. On the other hand, because the first shielding structure 122 is provided with the first opening 1221 and the second opening 1222, the first shielding structure 122 can use the first opening 1221 and the second opening 1222 to release water vapor generated during the evaporation process of the pixel 121. This can reduce the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby improving the display quality of the display panel 100.

[0290] In some embodiments, the border area 102 is located on at least one side of the display area 101 along the first direction F1 , and the second shielding structure 1121 and the third shielding structure 1123 are disposed in the same layer and spaced apart along the first direction F1 .

[0291] Forming the second shielding structure 1121 and the third shielding structure 1123 in the same manufacturing process can reduce the manufacturing process time of the display panel 100 , thereby improving the manufacturing efficiency of the display panel 100 .

[0292] In some embodiments, the dimension of the third shielding structure 1123 along the first direction F1 is greater than the dimension of the second shielding structure 1121 along the first direction F1. The first shielding structure 122 is penetrated by a plurality of first openings 1221 corresponding to the second shielding structure 1121, and a plurality of second openings 1222 corresponding to the third shielding structure 1123. The number of second openings 1222 corresponding to the third shielding structure 1123 is greater than the number of first openings 1221 corresponding to the second shielding structure 1121.

[0293] On the one hand, the first shielding structure 122 can utilize the plurality of first openings 1221 and the plurality of second openings 1222 to release moisture formed during the evaporation process of the sub-pixels 121, thereby effectively reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby improving the display quality of the display panel 100. On the other hand, the number of first openings 1221 can be appropriately arranged based on the size of the second shielding structure 1121 along the first direction F1, and the number of second openings 1222 can be appropriately arranged based on the size of the third shielding structure 1123 along the first direction F1. This achieves the goal of utilizing the first, second, and third shielding structures 122, 1121, and 1123 to collectively reduce interference between touch signals and drive signals, while also effectively reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, thereby improving the display quality of the display panel 100.

[0294] In some embodiments, the array layer group 112 includes at least two third shielding structures 1123 located on at least one side of the second shielding structure 1121 along the first direction F1 .

[0295] In this embodiment, the array layer assembly 112 further includes a plurality of metal traces 1122 located in the border region 102 and spaced apart along the first direction F1. The metal traces 1122 and the second shielding structure 1121 are disposed on the same layer and are insulated from each other. Along the first direction F1, the second shielding structure 1121 is located between two adjacent metal traces 1122. At least two third shielding structures 1123 are located on either side of the overall structure formed by the plurality of metal traces 1122 and the second shielding structure 1121, along the first direction F1.

[0296] In this way, more second openings 1222 can be set on the first shielding structure 122. The first shielding structure 122 can use more second openings 1222 to release water vapor formed by the evaporation process of the factor pixels 121, thereby better reducing the probability of the first shielding structure 122 becoming uneven or peeling off from the array substrate 110, which is beneficial to improving the display effect of the display panel 100.

[0297] In some embodiments, the first shielding structure 122 extends from a side close to the display area 101 toward a side away from the display area 101 .

[0298] It can be understood that the first shielding structure 122 is a full-surface structure, and the first shielding structure 122 , the second shielding structure 1121 and the third shielding structure 1123 can be better utilized to reduce interference between the touch signal and the driving signal.

[0299] In some embodiments, a side of the first shielding structure 122 away from the display area 101 extends to cover the third shielding structure 1123 further away from the display area 101 .

[0300] In other words, the side of the first shielding structure 122 away from the display area 101 overlaps with the third shielding structure 1123, which is further away from the display area 101, facilitating connection of an external driver chip to the third shielding structure 1123, which is further away from the display area 101. This allows the driver chip to provide shielding signals to both the third shielding structure 1123 and the first shielding structure 122, and the electrically connected third shielding structure 1123 and first shielding structure 122 can further reduce interference between touch signals and drive signals.

[0301] Optionally, the shielding signal has the same potential as the low-level signal VSS.

[0302] In some embodiments, a side of the first shielding structure 122 close to the display area 101 extends to cover the third shielding structure 1123 closer to the display area 101 .

[0303] That is, the side of the first shielding structure 122 close to the display area 101 overlaps with the third shielding structure 1123 closer to the display area 101. In this way, the electrically connected third shielding structure 1123 and the first shielding structure 122 can be used to better reduce the interference between the touch signal and the driving signal.

[0304] In some other embodiments, the side of the first shielding structure 122 away from the display area 101 extends to cover the third shielding structure 1123 further away from the display area 101, and the side of the first shielding structure 122 close to the display area 101 extends to cover the third shielding structure 1123 closer to the display area 101.

[0305] In this way, the driving chip can provide shielding signals to the third shielding structure 1123 and the first shielding structure 122 , and the electrically connected third shielding structure 1123 and the first shielding structure 122 can be used to better reduce interference between touch signals and driving signals.

[0306] In some embodiments, the first shielding structure 122 is electrically connected to the second shielding structure 1121 and the third shielding structure 1123 , respectively.

[0307] In this way, the electrically connected first shielding structure 122 , second shielding structure 1121 , and third shielding structure 1123 can be used to better reduce interference between the touch signal and the driving signal.

[0308] Optionally, a via connection structure 114 is provided on the array layer group 112 , and the first shielding structure 122 is electrically connected to the second shielding structure 1121 through the via connection structure 114 .

[0309] The first shielding structure 122 and the second shielding structure 1121 are electrically connected through the via connection structure 114. The first shielding structure 122 and the second shielding structure 1121 can be well utilized to reduce the interference between the touch signal and the driving signal, so that the first shielding structure 122 and the second shielding structure 1121 form a combined shielding effect.

[0310] In some embodiments, the first shielding structure 122 overlaps the third shielding structure 1123 .

[0311] Specifically, the side of the first shielding structure 122 away from the display area 101 extends to cover the third shielding structure 1123 further away from the display area 101 , and the side of the first shielding structure 122 close to the display area 101 extends to cover the third shielding structure 1123 closer to the display area 101 .

[0312] The first shielding structure 122 and the third shielding structure 1123 can form a combined shielding effect to better reduce the interference between the touch signal and the driving signal.

[0314] The display device 10 can be a mobile or fixed terminal with a display panel 100, such as a mobile phone, a television, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a personal digital assistant (PDA), a navigation device, a smart watch, a virtual reality device, etc.

[0315] See also Figure 9 According to a fourth aspect of the present application, a method for manufacturing a display panel is provided, comprising:

[0316] S10 , providing an array substrate, wherein the array substrate includes a stacked substrate and an array layer group.

[0317] S20 , forming a plurality of sub-pixels located in the display area and a shielding structure located in the frame area on a side of the array layer group away from the substrate.

[0318] S30 , forming a conductive layer on a side of the shielding structure away from the substrate.

[0319] The orthographic projection of the shielding structure on the substrate covers the orthographic projection of the conductive layer on the substrate.

[0320] In this way, the shielding structure can be used to reduce the interference between the touch signal from the conductive layer and the driving signal from the array substrate, thereby enabling the array layer group to better provide corresponding driving signals to the sub-pixels, thereby improving the display effect of the display panel.
