[0088] FIG. 1 is a top view of a display device according to some embodiments.

[0089] 1 , some embodiments of the present disclosure provide a display device 100 , which includes a display panel 200 .

[0090] The display device 100 may be a liquid crystal display (LCD); the display device 100 may also be an electroluminescent display or a photoluminescent display. If the display device 100 is an electroluminescent display, the electroluminescent display may be an organic light-emitting diode (OLED) display or a quantum dot light-emitting diode (QLED) display. If the display device 100 is a photoluminescent display, the photoluminescent display may be a quantum dot photoluminescent display.

[0091] The display device 100 described above can be any device that displays images, whether in motion (e.g., video) or stationary (e.g., still images), and whether textual or graphic. More specifically, it is contemplated that the embodiments described may be implemented in or associated with a variety of electronic devices, such as, but not limited to, mobile phones, wireless devices, personal data assistants (PDAs), handheld or portable computers, GPS receivers / navigators, cameras, MP4 video players, camcorders, game consoles, watches, clocks, calculators, television monitors, flat-panel displays, computer monitors, automotive displays (e.g., speedometer displays, etc.), navigation systems, cockpit controls and / or displays, displays of camera views (e.g., displays of rearview cameras in vehicles), electronic photographs, electronic billboards or signs, projectors, architectural structures, packaging, and aesthetic structures (e.g., displays of images of a piece of jewelry), and the like.

[0092] The following embodiments of the present disclosure are described by taking the display device 100 as an OLED display device as an example. In this case, the display panel 200 is an OLED display panel.

[0093] Current OLED display panels generally use AA Hole (Active Area Hole) technology and Full Display with Camera (FDC) technology. AA Hole technology refers to drilling a hole in the OLED display panel (mounting hole H of the display panel 200 in Figure 1). The hole is used to place functional devices such as a camera, which can effectively utilize screen space and increase the screen-to-body ratio (i.e., the ratio of the area of ​​the display area actually used to display the image to the area of ​​the entire front of the display panel).

[0094] FIG. 2 is a cross-sectional view of the display panel along section line AA′ in FIG. 1 .

[0095] In some embodiments, as shown in FIG. 2 , the display panel 200 includes a display substrate 1 and a touch structure 2 . The touch structure 2 is disposed on the light-emitting side E of the display substrate 1 .

[0096] As shown in FIG2 , the display substrate 1 includes a base substrate 10 and a plurality of sub-pixels P disposed on the base substrate 10. Each sub-pixel P includes a pixel driving circuit D and a light-emitting device L disposed on the base substrate 10. The pixel driving circuit D includes a plurality of thin-film transistors (TFTs). The light-emitting device L includes an anode L1, a light-emitting functional layer L2, and a cathode L3. The anode L1 is electrically connected to the drain (or source) of the thin-film transistor TFT serving as the driving transistor among the plurality of thin-film transistors.

[0097] As shown in FIG. 2 , the display substrate 1 further includes a planar layer 11 disposed between the thin film transistor TFT and the anode L1 .

[0098] As shown in FIG2 , the display substrate 1 further includes a pixel defining layer 12, which includes a plurality of openings 120. Each light-emitting device L is disposed in one of the openings 120. In some embodiments, the light-emitting functional layer L2 includes a light-emitting layer. In other embodiments, in addition to the light-emitting layer, the light-emitting functional layer L2 further includes one or more of an electron transporting layer (ETL), an electron injection layer (EIL), a hole transporting layer (HTL), and a hole injection layer (HIL).

[0099] The above-mentioned display panel 200 can be a top-emitting display panel, in which case, the anode L1 close to the base substrate 10 is opaque, and the cathode L3 away from the base substrate 10 is transparent or translucent; the display panel 200 can also be a bottom-emitting display panel, in which case, the anode L1 close to the base substrate 10 is transparent or translucent, and the cathode L3 away from the base substrate 10 is opaque; the display panel 200 can also be a double-sided light-emitting display panel, in which case, the anode L1 close to the base substrate 10 and the cathode L3 away from the base substrate 10 are both transparent or translucent.

[0100] In some embodiments, as shown in FIG. 2 , the display substrate 1 further includes a thin film encapsulation layer 13 disposed on a side of the light emitting device L away from the base substrate 10 .

[0101] Exemplarily, the thin-film encapsulation layer 13 includes a first inorganic barrier layer 131, an organic barrier layer 132, and a second inorganic barrier layer 133. The first inorganic barrier layer 131, the organic barrier layer 132, and the second inorganic barrier layer 133 are sequentially stacked and disposed on a side of the light-emitting device L away from the base substrate 10. The first inorganic barrier layer 131 and the second inorganic barrier layer 133 function to block water vapor and oxygen, while the organic barrier layer 132 has a certain degree of flexibility and the function of absorbing water vapor, so that the formed thin-film encapsulation layer 13 has good encapsulation performance.

[0102] In some embodiments, as shown in FIG2 , an On-Cell technology structural design is adopted, and the touch structure 2 is directly disposed on the thin film encapsulation layer 13 , that is, no other film layer is disposed between the touch structure 2 and the thin film encapsulation layer 13 , which is beneficial to reducing the thickness of the display panel 200 , thereby achieving a thinner and lighter display panel 200 .

[0103] Figure 3 is a top view of a display panel according to some embodiments; Figure 4A is a partial enlarged view of the display panel at M in Figure 3; Figure 4B is a cross-sectional view of the display panel along section line BB' in Figure 4A; Figure 4C is another partial enlarged view of the display panel at M in Figure 3; Figure 4D is a cross-sectional view of the display panel along section line CC' in Figure 4C; Figure 5 is a partial enlarged view of the display panel at N in Figure 3; Figure 6 is a partial enlarged view of the display panel at P in Figure 5; and Figure 7 is a cross-sectional view of the display panel along section line DD' in Figure 6.

[0104] 3 , the display panel 200 includes a touch structure 2 . The touch structure 2 has a touch area TA. The touch area TA includes a main touch area A1 and a corner area A2 . The corner area A2 is located around the main touch area A1 .

[0106] Continuing to refer to Figures 3 and 4A, multiple second touch units 22 extend along direction X. One second touch unit 22 includes multiple second touch electrodes 220 and multiple second connection bridges 221. The second touch electrodes 220 and the second connection bridges 221 are alternately arranged along direction X, that is, one second connection bridge 221 electrically connects two adjacent second touch electrodes 220.

[0107] It should be noted that one of the first touch electrode 210 and the second touch electrode 220 is a TX (touch drive electrode) and the other is an RX (touch sensing electrode). The sides of adjacent first touch electrodes 210 and second touch electrodes 220 face each other. When electrical signals are transmitted between the first touch electrodes 210 and the second touch electrodes 220, mutual capacitance is generated between the adjacent first touch electrodes 210 and the second touch electrodes 220. When a finger touches the display panel 200, the finger removes the charge on the touch electrodes, causing the mutual capacitance between the touch electrodes at the touch location to change. The touch IC in the display panel 200 can detect the change in mutual capacitance between the touch electrodes to identify the finger's touch location, thereby realizing the touch function of the display panel 200.

[0108] Furthermore, the above-mentioned direction X and direction Y intersect, for example, direction X is perpendicular to direction Y. In FIG3 , direction X is a horizontal direction and direction Y is a vertical direction, but the embodiments of the present disclosure are not limited thereto. In other embodiments, direction X may also be a vertical direction and direction Y may also be a horizontal direction.

[0111] It should be noted that the touch structure 2 further includes a buffer layer 20 . The buffer layer 20 is located between the display substrate 1 and the first conductive layer 2 a and serves as an insulator.

[0112] Continuing with Figure 4B , the first touch electrodes 210, second touch electrodes 220, and second connection bridges 221 are located in the second conductive layer 2c, while the first connection bridges 211 are located in the first conductive layer 2a. Along direction X, two adjacent second touch electrodes 220 are directly electrically connected via the second connection bridges 221. Along direction Y, the first connection bridges 211 pass through different via holes H in the insulating layer 2b to electrically connect to two adjacent first touch electrodes 210.

[0113] Alternatively, referring to Figures 4C and 4D , the first touch electrodes 210, the second touch electrodes 220, and the first connection bridges 211 are located in the second conductive layer 2c, while the second connection bridges 221 are located in the first conductive layer 2a. Along direction Y, two adjacent first touch electrodes 210 are directly electrically connected via the first connection bridges 211. Along direction X, the second connection bridges 221 pass through different via holes H in the insulating layer 2b to electrically connect to two adjacent second touch electrodes 220.

[0114] In addition, referring to FIG. 4B and FIG. 4D , the touch structure 2 further includes a protection layer 2 d disposed on a side of the second conductive layer 2 c away from the display substrate 1 , which plays a role in protecting the touch structure 2 and providing insulation.

[0115] The touch structure 2 is designed using the FMLOC (Flexible Multi-Layer On Cell) technology, which uses two conductive layers to form the first touch electrode 210 , the second touch electrode 220 , the first connecting bridge 211 and the second connecting bridge 221 .

[0116] 3 and 5 , the provision of the mounting hole H will destroy the integrity of the touch electrodes in the touch structure 2 and affect the provision of the first connecting bridge 211 and the second connecting bridge 221 , making it impossible for the first touch electrodes 210 located at the edge of the mounting hole H to be connected to each other, and making it impossible for the second touch electrodes 220 located at the edge of the mounting hole H to be connected to each other.

[0117] To achieve normal connection of the touch electrodes around the mounting hole H, a jumper structure T may be used. The following describes the design of the corresponding jumper structure T based on the number of first touch units 21 and second touch units 22 passing through the mounting hole H.

[0118] 3 and 5 , a first touch unit 21 and a second touch unit 22 pass through the mounting hole H. In the first touch unit 21, the plurality of first touch electrodes 210 include at least one first electrode K1 and at least one second electrode K2 located around the mounting hole H. For example, the plurality of first touch electrodes 210 include a first electrode K1 and a second electrode K2 located around the mounting hole H. The mounting hole H destroys the integrity of the two first touch electrodes 210 (the first electrode K1 and the second electrode K2).

[0119] In the second touch unit 22, the plurality of second touch electrodes 220 include at least one third electrode K3 and at least one fourth electrode K4 located around the mounting hole H. For example, the plurality of second touch electrodes 220 include a third electrode K3 and a fourth electrode K4 located around the mounting hole H, and the mounting hole H destroys the integrity of the two second touch electrodes 220 (the third electrode K3 and the fourth electrode K4).

[0120] Based on this, referring to FIG5 , a jumper structure T is provided around the mounting hole H. The jumper structure T includes a first connecting wire L1, two second connecting wires L2, and at least one connecting pattern L. The first connecting wire L1 directly connects the first electrode K1 and the second electrode K2 to achieve normal connection between the first electrode K1 and the second electrode K2.

[0121] Referring to Figures 5, 6, and 7, one of the two second connection lines L2 is directly connected to the third electrode K3, and the other is directly connected to the fourth electrode K4. The first connection line L1 and the two second connection lines L2 are located in the second conductive layer 2c, and the connection pattern L is located in the first conductive layer 2a. The first connection line L1 and the two second connection lines L2 are arranged in parallel and spaced apart, and the two second connection lines L2 are located on either side of the first connection line L1. The connection pattern L spans the first connection line L1, and its two ends pass through the insulating layer 2b to connect to the two second connection lines L2, respectively, thereby achieving a normal connection between the third electrode K3 and the fourth electrode K4.

[0122] FIG. 8 is another partial enlarged view of the display panel at position N in FIG. 3 .

[0123] In other embodiments, referring to FIG8 , two first touch units 21 and two second touch units 22 pass through the mounting hole H. It can be understood that, compared with the mounting hole H shown in FIG5 , the diameter of the mounting hole H shown in FIG8 is larger, and the number of touch electrodes destroyed by the mounting hole H is greater.

[0124] Each first touch unit 21 includes a first electrode K1 and a second electrode K2 located around a mounting hole H. The mounting hole H destroys the integrity of the first electrode K1 and the second electrode K2 in each first touch unit 21 .

[0125] Each second touch-sensing unit 22 includes a third electrode K3 and a fourth electrode K4 located around the mounting hole H. The mounting hole H destroys the integrity of the third electrode K3 and the fourth electrode K4 in each second touch-sensing unit 22 .

[0126] Based on this, multiple jumper structures T are arranged around the mounting hole H. A first connection line L1 in a jumper structure T directly connects the first electrode K1 and the second electrode K2 of the same first touch unit 21 to achieve normal connection between the first electrode K1 and the second electrode K2.

[0127] Continuing with Figure 8 , in the same jumper structure T, one of the two second connection lines L2 is designated as the first target lead L21, and the other is designated as the second target lead L22. The first target lead L21 includes a first line segment L21a and a second line segment L21b, which are separately arranged. In the same second touch-sensing unit 22, the third electrode K3 is directly connected to the first line segment L21a, and the fourth electrode K4 is directly connected to the second line segment L21b. At least one connection pattern L spans the first connection line L1 of one jumper structure T, with one end connected to the first line segment L21a and the other end connected to the second target lead L22. At least one connection pattern L spans the first connection line L1 of another jumper structure T, with one end connected to the second target lead L22 and the other end connected to the second line segment L21b, thereby achieving a proper connection between the third electrode K3 and the fourth electrode K4.

[0128] In some embodiments, as shown in FIG. 8 , in the jumper structure T, the first connecting line L1 and the second connecting line L2 are arranged along the edge of the mounting hole H, and the length extension direction of the connecting pattern L passes through the mounting hole H.

[0129] By adopting the above arrangement method, the jumper structure T can be arranged compactly, reducing the area occupied by the jumper structure T around the mounting hole H, thereby increasing the setting area of ​​the touch electrode around the mounting hole H, and increasing the facing area between the side surfaces of the touch electrodes, which is beneficial to improving the touch performance around the mounting hole H.

[0130] As shown in FIG8 , the distance D1 between the edge of the first electrode K1 near the mounting hole H and the mounting hole H is smaller than the distance D3 between the edge of the third electrode K3 near the mounting hole H and the mounting hole H, and is also smaller than the distance D4 between the edge of the fourth electrode K4 near the mounting hole H and the mounting hole H. The distance D2 between the edge of the second electrode K2 near the mounting hole H and the mounting hole H is smaller than the distance D3 between the edge of the third electrode K3 near the mounting hole H and the mounting hole H, and is also smaller than the distance D4 between the edge of the fourth electrode K4 near the mounting hole H and the mounting hole H.

[0131] Moreover, the distances between the first line segment L21a of the first target lead L21, the first connecting line L1 and the second target lead L22 and the mounting hole H decrease successively, and the distances between the second line segment L21b of the first target lead L21, the first connecting line L1 and the second target lead L22 and the mounting hole H decrease successively.

[0132] It can be understood that, in combination with Figure 8, the distance between the third electrode K3 and the fourth electrode K4 near the edge of the mounting hole H and the mounting hole H is larger, the distance between the first electrode K1 and the second electrode K2 near the edge of the mounting hole H and the mounting hole H is smaller, and the distance between the first target lead L21, the first connecting line L1 and the second target lead L22 and the mounting hole H decreases successively.

[0133] Based on the above arrangement design, the edges of the first to fourth electrodes K1 to K4 near the mounting hole H are adapted to the routing arrangement of the first target lead L21, the first connecting line L1, and the second target lead L22, thereby realizing the connection between the first target lead L21 and the third electrode K3 and the fourth electrode K4, and the connection between the first connecting line L1 and the first electrode K1 and the second electrode K2, and avoiding the problem of cross short circuit between the connecting lines in the second conductive layer 2c.

[0134] In some embodiments, as shown in FIG8 , each first touch unit 21 further includes at least one fifth electrode K5 located around the mounting hole H. For example, each first touch unit 21 further includes a fifth electrode K5 located around the mounting hole H, that is, the mounting hole H destroys the integrity of the three first touch electrodes 210 (the first electrode K1, the second electrode K2, and the fifth electrode K5) in each first touch unit 21.

[0135] The fifth electrode K5 is located between the first electrode K1 and the second electrode K2 along the direction Y, and is connected to the first connection line L1. In other words, the first electrode K1 is connected to the fifth electrode K5 through the first connection line L1, and the fifth electrode K5 is connected to the second electrode K2 through the first connection line L1.

[0136] By adding the fifth electrode K5 around the mounting hole H, mutual capacitance is generated between the fifth electrode K5 and the adjacent third electrode K3 and fourth electrode K4, which is beneficial to improving the touch performance around the mounting hole H.

[0137] As shown in Figure 8, each second touch unit 22 also includes at least one sixth electrode K6 located around the mounting hole H. For example, each second touch unit 22 also includes a sixth electrode K6 located around the mounting hole H, that is, the mounting hole H destroys the integrity of the three second touch electrodes 220 (the third electrode K3, the fourth electrode K4 and the sixth electrode K6) in each second touch unit 22.

[0138] Along direction X, the sixth electrode K6 is located between the third electrode K3 and the fourth electrode K4, and is connected to the second target lead L22. Equivalently, the third electrode K3 is connected to the sixth electrode K6 via the first line segment L21a, at least one connection pattern L, and the second target lead L22, and the sixth electrode K6 is connected to the fourth electrode K4 via the second target lead L22, at least one connection pattern L, and the second line segment L21b.

[0139] By adding the sixth electrode K6 around the mounting hole H, mutual capacitance is generated between the sixth electrode K6 and the adjacent first electrode K1 and second electrode K2, which is beneficial to improving the touch performance around the mounting hole H.

[0140] FIG. 9A is another partial enlarged view of the display panel at position N in FIG. 3 .

[0141] 9A , a first touch unit 21 and a second touch unit 22 pass through the mounting hole H. The first connection line L1 directly connects the third electrode K3 and the fourth electrode K4 to achieve normal connection between the third electrode K3 and the fourth electrode K4.

[0142] One of the two second connection lines L2 is directly connected to the first electrode K1, and the other is directly connected to the second electrode K2. The connection pattern L crosses the first connection line L1, and the two ends of the connection pattern L pass through the insulating layer 2b and are respectively connected to the two second connection lines L2, thereby achieving normal connection between the first electrode K1 and the second electrode K2.

[0143] FIG9B is another partial enlarged view of the display panel at position N in FIG3 .

[0144] In other embodiments, as shown in FIG9B , two first touch units 21 and two second touch units 22 pass through the mounting hole H. A plurality of jumper structures T are disposed around the mounting hole H, and a first connection line L1 in a jumper structure T directly connects the third electrode K3 and the fourth electrode K4 of the same second touch unit 22 to achieve normal connection between the third electrode K3 and the fourth electrode K4.

[0145] Continuing with Figure 9B , in the same jumper structure T, one of the two second connection lines L2 is designated as the first target lead line L21, and the other is designated as the second target lead line L22. The first target lead line L21 includes a first line segment L21a and a second line segment L21b, which are separately arranged. In the same first touch unit 21, the first electrode K1 is directly connected to the first line segment L21a, and the second electrode K2 is directly connected to the second line segment L21b. At least one connection pattern L spans the first connection line L1 of one jumper structure T, with one end connected to the first line segment L21a and the other end connected to the second target lead line L22. At least one connection pattern L spans the first connection line L1 of another jumper structure T, with one end connected to the second target lead line L22 and the other end connected to the second line segment L21b, thereby achieving a normal connection between the first electrode K1 and the second electrode K2.

[0146] In some embodiments, as shown in FIG. 9B , in the jumper structure T, the first connecting line L1 and the second connecting line L2 are arranged along the edge of the mounting hole H, and the length extension direction of the connecting pattern L passes through the mounting hole H.

[0147] By adopting the above arrangement method, the jumper structure T can be arranged compactly, reducing the area occupied by the jumper structure T around the mounting hole H, thereby increasing the setting area of ​​the touch electrode around the mounting hole H, and increasing the facing area between the side surfaces of the touch electrodes, which is beneficial to improving the touch performance around the mounting hole H.

[0148] As shown in FIG9B , a distance D3 between the edge of the third electrode K3 near the mounting hole H and the mounting hole H is smaller than a distance D1 between the edge of the first electrode K1 near the mounting hole H and the mounting hole H, and is also smaller than a distance D2 between the edge of the second electrode K2 near the mounting hole H and the mounting hole H. A distance D4 between the edge of the fourth electrode K4 near the mounting hole H and the mounting hole H is smaller than a distance D1 between the edge of the first electrode K1 near the mounting hole H and the mounting hole H, and is also smaller than a distance D2 between the edge of the second electrode K2 near the mounting hole H and the mounting hole H.

[0149] Moreover, the distances between the first line segment L21a of the first target lead L21, the first connecting line L1 and the second target lead L22 and the mounting hole H decrease successively, and the distances between the second line segment L21b of the first target lead L21, the first connecting line L1 and the second target lead L22 and the mounting hole H decrease successively.

[0150] It can be understood that, in conjunction with Figure 9B, the distance between the first electrode K1 and the second electrode K2 near the edge of the mounting hole H and the mounting hole H is larger, the distance between the third electrode K3 and the fourth electrode K4 near the edge of the mounting hole H and the mounting hole H is smaller, and the distance between the first target lead L21, the first connecting line L1, the second target lead L22 and the mounting hole H decreases successively.

[0151] Based on the above arrangement design, the edges of the first to fourth electrodes K1 to K4 near the mounting hole H are adapted to the routing arrangement of the first target lead L21, the first connecting line L1, and the second target lead L22, thereby achieving the connection between the first target lead L21 and the first electrode K1 and the second electrode K2, as well as the connection between the first connecting line L1 and the third electrode K3 and the fourth electrode K4, and avoiding the problem of cross short circuit between the connecting lines in the second conductive layer 2c.

[0152] In some embodiments, as shown in FIG9B , each first touch unit 21 further includes at least one fifth electrode K5 located around the mounting hole H. For example, each first touch unit 21 further includes a fifth electrode K5 located around the mounting hole H, that is, the mounting hole H destroys the integrity of the three first touch electrodes 210 (the first electrode K1, the second electrode K2, and the fifth electrode K5) in each first touch unit 21.

[0153] Along direction Y, the fifth electrode K5 is located between the first electrode K1 and the second electrode K2, and is connected to the second target lead L22. Equivalently, the first electrode K1 is connected to the fifth electrode K5 via the first line segment L21a, at least one connection pattern L, and the second target lead L22, while the fifth electrode K5 is connected to the second electrode K2 via the second target lead L22, at least one connection pattern L, and the second line segment L21b.

[0154] By adding the fifth electrode K5 around the mounting hole H, mutual capacitance is generated between the fifth electrode K5 and the adjacent third electrode K3 and fourth electrode K4, which is beneficial to improving the touch performance around the mounting hole H.

[0155] As shown in Figure 9B, each second touch unit 22 also includes at least one sixth electrode K6 located around the mounting hole H. For example, each second touch unit 22 also includes a sixth electrode K6 located around the mounting hole H, that is, the mounting hole H destroys the integrity of the three second touch electrodes 220 (the third electrode K3, the fourth electrode K4 and the sixth electrode K6) in each second touch unit 22.

[0156] The sixth electrode K6 is located between the third electrode K3 and the fourth electrode K4 along the direction X, and is connected to the first connection line L1. This means that the third electrode K3 is connected to the sixth electrode K6 through the first connection line L1, and the sixth electrode K6 is connected to the fourth electrode K4 through the first connection line L1.

[0157] By adding the sixth electrode K6 around the mounting hole H, mutual capacitance is generated between the sixth electrode K6 and the adjacent first electrode K1 and second electrode K2, which is beneficial to improving the touch performance around the mounting hole H.

[0158] In some embodiments, referring to FIG. 3 and FIG. 9B , the areas of the first electrode K1 , the second electrode K2 , the third electrode K3 , and the fourth electrode K4 are all smaller than the areas of the touch electrodes not penetrated by the mounting hole H (the first touch electrode 210 and the second touch electrode 220 ).

[0159] As can be seen from the above, compared with the touch electrode not penetrated by the mounting hole H (touch electrode with a complete pattern), the mounting hole H destroys the integrity of the pattern of the first electrode K1, the second electrode K2, the third electrode K3 and the fourth electrode K4, so that the areas of the first electrode K1, the second electrode K2, the third electrode K3 and the fourth electrode K4 are all smaller than the area of ​​the touch electrode not penetrated by the mounting hole H.

[0160] Furthermore, within the same first touch unit 21, the area of ​​the fifth electrode K5 is smaller than that of the first electrode K1 and smaller than that of the second electrode K2. In other words, by adding the smaller fifth electrode K5, the fifth electrode K5 can fill the area surrounding the mounting hole H, improving the area utilization of the area surrounding the mounting hole H. Furthermore, the fifth electrode K5 generates mutual capacitance with the adjacent third electrode K3 and fourth electrode K4, which helps improve touch performance around the mounting hole H.

[0161] Similarly, in the same second touch unit 22, the area of ​​the sixth electrode K6 is smaller than that of the third electrode K3, and smaller than that of the fourth electrode K4. In other words, by adding the smaller sixth electrode K6, the sixth electrode K6 can fill the area around the mounting hole H, improving the area utilization of the area around the mounting hole H. Furthermore, the sixth electrode K6 generates mutual capacitance with the adjacent first electrode K1 and second electrode K2, which helps improve touch performance around the mounting hole H.

[0162] FIG. 10 is another partial enlarged view of the display panel at position N in FIG. 3 .

[0163] 10 , a distance D1 between the edge of the first electrode K1 close to the mounting hole H and the mounting hole H, a distance D2 between the edge of the second electrode K2 close to the mounting hole H and the mounting hole H, a distance D3 between the edge of the third electrode K3 close to the mounting hole H and the mounting hole H, and a distance D4 between the edge of the fourth electrode K4 close to the mounting hole H and the mounting hole H are all equal.

[0164] Moreover, the distances between the first line segment L21a of the first target lead L21, the first connecting line L1 and the second target lead L22 and the mounting hole H decrease successively, and the distances between the second line segment L21b of the first target lead L21, the first connecting line L1 and the second target lead L22 and the mounting hole H decrease successively.

[0165] Continuing to refer to FIG10 , the line width of the first connection line L1 varies. The line width of the portion of the first connection line L1 located between the second touch electrode 220 (the third electrode K3 or the fourth electrode K4) and the mounting hole H is assumed to be G1. The line width of the portion of the first connection line L1 located between the first touch electrode 210 (the first electrode K1 or the second electrode K2) and the mounting hole H is assumed to be G2, and G1>G2.

[0166] Based on this, let the line width of the first line segment L21a be G3, and let the distance between the first line segment L21a and the first connecting line L1 be G4, then G1 = G2 + G3 + G4. Let the line width of the second line segment L21b be G5, and let the distance between the second line segment L21b and the first connecting line L1 be G6, then G1 = G2 + G5 + G6.

[0167] Based on the above arrangement design, the edges of the first to fourth electrodes K1 to K4 near the mounting hole H are adapted to the routing arrangement of the first target lead L21, the first connecting line L1, and the second target lead L22, thereby achieving the connection between the first target lead L21 and the first electrode K1 and the second electrode K2, as well as the connection between the first connecting line L1 and the third electrode K3 and the fourth electrode K4, and avoiding the problem of cross short circuit between the connecting lines in the second conductive layer 2c.

[0168] However, in the related art, FIG11A is a structural diagram of a touch structure in the related art; FIG11B is a cross-sectional view of the display panel along section line EE' in FIG11A; and FIG12A and FIG12B are step diagrams for preparing a jumper structure in the related art.

[0169] Referring to Figures 11A and 11B, there is also a wire R' in the second conductive layer 2c'. The length extension direction of the wire R' is roughly parallel to the length extension direction of the connection pattern L', and the wire R' is close to the bottom chamfer of the connection pattern L'. The wire R' connects the first connection line L1' and the second connection line L2', which will cause a short circuit between the touch electrode connected to the first connection line L1' and the touch electrode connected to the second connection line L2', thereby affecting the touch performance of the touch structure.

[0170] The inventors of the present disclosure have discovered through research that the reason why the wire R' exists in the second conductive layer 2c' is that:

[0171] In the display substrate 1', the organic barrier layer in the thin film encapsulation layer is usually prepared using inkjet printing (IJP) technology. Due to the fluidity of the ink, the surface of the ink near the mounting hole is relatively low and uneven. After the ink dries, the portion of the organic barrier layer near the mounting hole becomes thinner and has an uneven surface, which in turn causes the upper surface of the display substrate 1' to be uneven.

[0172] During the fabrication of the jumper structure T', referring to Figures 12A and 12B, a connection pattern L', an insulating layer 2b', a second conductive layer 2c', and a photoresist layer PR are sequentially formed on a display substrate 1'. The photoresist layer PR is then exposed and developed to form a patterned photoresist layer PR. Because the bottom chamfer of the connection pattern L' is concave and the top surface of the display substrate 1' is uneven, the photoresist layer PR is likely to remain near the bottom chamfer of the connection pattern L'. Therefore, during the process of patterning the second conductive layer 2c' using the photoresist layer PR as a mask, material from the second conductive layer 2c' remains beneath the remaining photoresist layer PR, forming the aforementioned conductive line R'.

[0173] To solve the above problems, some embodiments of the present disclosure provide a touch structure 2. FIG. 13A and FIG. 13B are structural diagrams of a touch structure according to some embodiments.

[0174] As shown in FIG13A , in the jumper structure T of the touch structure 2, the spacing between the first connection line L1 and the second connection line L2 is a first dimension C1. In the portion of the connection pattern L located between the first connection line L1 and the second connection line L2, the length of the outline from the first connection line L1 to the second connection line L2 is a second dimension C2, and the second dimension C2 is greater than the first dimension C1.

[0175] In the above-mentioned embodiment of the present disclosure, the length C2 of the outline of the connection pattern L located between the first connection line L1 and the second connection line L2 is greater than the spacing C1 between the first connection line L1 and the second connection line L2. Compared with the jumper structure shown in Figure 11A, the length C2 of the outline of the connection pattern L located between the first connection line L1 and the second connection line L2 is increased.

[0176] Based on this, in the process of preparing the jumper structure T, referring to FIG13B , as the length C2 of the outline of the connection pattern L increases, the length of the wire R increases, and disconnections are more likely to occur in the wire R, thereby reducing the risk of the wire R connecting the first connection line L1 with the second connection line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0177] In some embodiments, referring to FIG. 13A , the connection pattern L includes a first connection portion a1 and two first conductive portions a2 disposed at both ends of the first connection portion a1 , and a dimension C3 of the first conductive portion a2 along the first direction U is greater than a dimension C4 of the first connection portion a1 along the first direction U.

[0178] It should be noted that the “first direction U” is substantially parallel to the extension direction of the first connection line L1. When the first connection line L1 is a curve, the “first direction U” may be substantially parallel to the tangent direction of the first connection line L1.

[0179] Continuing with Figure 13A , the first connection portion a1 of the connection pattern L spans the first connection line L1. The two first conductive portions a2 correspond one-to-one with the two second connection lines L2. Each first conductive portion a2 passes through the insulating layer 2b and connects to the corresponding second connection line L2. An edge B1 of the first conductive portion a2, on the side closest to the first connection line L1, extends beyond an edge B2 of the corresponding second connection line L2, on the side closest to the first connection line L1.

[0180] In the above-mentioned embodiment of the present disclosure, by setting the edge B1 of the first conductive portion a2 beyond the edge B2 of the corresponding second connection line L2, the length C2 of the contour of the connection pattern L between the first connection line L1 and the second connection line L2 is increased, thereby reducing the risk of short circuit between the first connection line L1 and the second connection line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0181] 14A and 14B are structural diagrams of another touch structure according to some embodiments.

[0182] In some embodiments, as shown in FIG. 14A , an edge B1 of the first conductive portion a2 close to the first connection line L1 extends beyond an edge B2 of the corresponding second connection line L2 close to the first connection line L1 .

[0183] Moreover, the dimension C3 of at least one first conductive portion a2 along the first direction U is substantially equal to the dimension C5 of the corresponding second connecting line L2 along the first direction U. For example, the dimensions C3 of the two first conductive portions a2 along the first direction U are both substantially equal to the dimension C5 of the corresponding second connecting line L2 along the first direction U. Based on this, the first conductive portion a2 and the second connecting line L2 form an overlapping double-layer routing.

[0184] In the above-mentioned embodiment of the present disclosure, the dimension C3 of the first conductive portion a2 along the first direction U is substantially equal to the dimension C5 of the corresponding second connecting line L2 along the first direction U, so that the length of the edge B1 of the first conductive portion a2 is substantially equal to the length of the edge B2 of the corresponding second connecting line L2.

[0185] Referring to FIG. 14B , since the edge B1 of the first conductive portion a2 extends beyond the edge B2 of the corresponding second connection line L2, and the length of the edge B1 of the first conductive portion a2 is substantially equal to the length of the edge B2 of the corresponding second connection line L2, the edge B1 of the first conductive portion a2 and the edge B2 of the corresponding second connection line L2 do not overlap. Therefore, during the preparation of the jumper structure T, the wire R does not contact and connect with the second connection line L2, thereby further reducing the risk of short circuit between the touch electrodes.

[0186] In some embodiments, as shown in FIG. 13A and FIG. 14A , an edge B1 of the first conductive portion a2 close to the first connection line L1 extends beyond an edge B2 of the corresponding second connection line L2 close to the first connection line L1 .

[0187] Furthermore, an edge B1 of at least one first conductive portion a2, which is closer to the first connection line L1, is substantially parallel to an edge B2 of the corresponding second connection line L2, which is closer to the first connection line L1. For example, edges B1 of two first conductive portions a2, which are closer to the first connection line L1, are substantially parallel to edges B2 of the corresponding second connection line L2, which are closer to the first connection line L1.

[0188] Through the above-mentioned configuration, the edge B1 of the first conductive portion a2 extends beyond the edge B2 of the corresponding second connection line L2, and the edge B1 of the first conductive portion a2 is roughly parallel to the edge B2 of the corresponding second connection line L2. This is beneficial for increasing the length C2 of the outline of the connection pattern L located between the first connection line L1 and the second connection line L2, reducing the risk of short circuit between the first connection line L1 and the second connection line L2, and thus reducing the risk of short circuit between the touch electrodes.

[0189] Furthermore, when the length of the edge B1 of the first conductive portion a2 is substantially equal to the length of the edge B2 of the corresponding second connection line L2, the wire R is prevented from contacting and connecting with the second connection line L2, thereby further reducing the risk of short circuit between the touch electrodes.

[0190] It can be seen that in the design of the jumper structure T, the edge B1 of the first conductive portion a2 must extend beyond the edge B2 of the corresponding second connecting line L2. Therefore, the inventors of the present disclosure studied the manufacturing process and found that the dimensional tolerance and positional tolerance of the connecting pattern L and the second connecting line L2 should be considered when meeting the above conditions.

[0191] As shown in FIG13A and FIG14A , an average distance D is set between an edge B1 of at least one first conductive portion a2 close to the first connection line L1 and an edge B2 of the corresponding second connection line L2 close to the first connection line L1 .

[0192] Assume that the dimensional tolerance of the first conductive portion a2 along the second direction V is CD1. It should be noted that the "second direction V" is approximately perpendicular to the extension direction of the first connecting line L1. If the first connecting line L1 is a curve, the "second direction V" can be approximately perpendicular to the tangent direction of the first connecting line L1. The positional tolerance of the first conductive portion a2 is OL1.

[0193] Assume that the dimensional tolerance of the second connecting line L2 along the second direction V is CD2, and the position tolerance of the second connecting line L2 is OL2.

[0194] In the case where the vacant area around the mounting hole H is large, the dimension of the edge B1 of the first conductive portion a2 extending beyond the edge B2 of the corresponding second connecting line L2 can be set larger, that is, the average distance D between the edge B1 of the first conductive portion a2 and the edge B2 of the corresponding second connecting line L2 can be set larger. Based on this,

[0195] In the case where the vacant area around the mounting hole H is small, the dimension of the edge B1 of the first conductive portion a2 extending beyond the edge B2 of the corresponding second connecting line L2 needs to be set smaller, that is, the average distance D between the edge B1 of the first conductive portion a2 and the edge B2 of the corresponding second connecting line L2 needs to be set smaller. Based on this,

[0196] FIG15A is a structural diagram of another touch structure according to some embodiments; FIG15B is a cross-sectional view of the touch structure in FIG15A along section line FF′.

[0197] As shown in FIG15A , an edge B3 of at least one first conductive portion a2 on a side away from the first connection line L1 extends beyond an edge B4 of the corresponding second connection line L2 on a side away from the first connection line L1 .

[0198] For example, the edges B3 of the two first conductive portions a2 on the side away from the first connection line L1 both extend beyond the edges B4 of the corresponding second connection line L2 on the side away from the first connection line L1 .

[0199] It can be understood that, referring to Figure 15B, the edge B1 of the first conductive part a2 on the side close to the first connecting line L1 exceeds the edge B2 of the corresponding second connecting line L2 on the side close to the first connecting line L1. In this case, the edge B3 of the first conductive part a2 on the side away from the first connecting line L1 exceeds the edge B4 of the corresponding second connecting line L2 on the side away from the first connecting line L1, which can make the surface of the insulating layer 2b covering the first conductive part a2 flatter. In the process of preparing the second connecting line L2, the second connecting line L2 is formed on a flat surface, which is conducive to reducing the dimensional tolerance of the second connecting line L2 and improving the dimensional accuracy of the second connecting line L2.

[0200] 16A and 16B are structural diagrams of another touch structure according to some embodiments.

[0201] 16A , the connection pattern L includes a second conductive portion a3 , and the orthographic projection of the first connection line L1 on the reference plane P overlaps with the orthographic projection of the second conductive portion a3 on the reference plane P. It should be noted that the “reference plane P” is the plane where the first conductive layer 2 a is located.

[0202] The second conductive portion a3 has two opposite edges along the second direction V, namely a first edge B5 and a second edge B6. The first connecting line L1 has two opposite edges along the second direction V, namely a third edge B7 and a fourth edge B8. The first edge B5 corresponds to the third edge B7 and extends beyond the third edge B7. The second edge B6 corresponds to the fourth edge B8 and extends beyond the fourth edge B8.

[0203] In the above-mentioned embodiment of the present disclosure, by setting the edge B5 of the second conductive portion a3 to extend beyond the edge B7 of the first connecting line L1, and the edge B6 of the second conductive portion a3 to extend beyond the edge B8 of the first connecting line L1, the length C2 of the contour of the connecting pattern L located between the first connecting line L1 and the second connecting line L2 is greater than the spacing C1 between the first connecting line L1 and the second connecting line L2. Compared with the jumper structure shown in Figure 11A, the length C2 of the contour of the connecting pattern L located between the first connecting line L1 and the second connecting line L2 is increased.

[0204] Based on this, in the process of preparing the jumper structure T, referring to FIG16B , as the length C2 of the outline of the connection pattern L increases, the length of the wire R increases, and disconnections are more likely to occur in the wire R, thereby reducing the risk of the wire R connecting the first connection line L1 with the second connection line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0205] 17A and 17B are structural diagrams of yet another touch structure according to some embodiments.

[0206] As shown in FIG. 17A , the first edge B5 of the second conductive portion a3 extends beyond the third edge B7 of the first connection line L1 , and the second edge B6 of the second conductive portion a3 extends beyond the fourth edge B8 of the first connection line L1 .

[0207] Furthermore, a dimension C6 of the second conductive portion a3 along the first direction U is substantially equal to a dimension C7 of the first connection line L1 along the first direction U. Therefore, the second conductive portion a3 and the first connection line L1 form overlapping double-layer traces.

[0208] In the above-mentioned embodiment of the present disclosure, the dimension C6 of the second conductive portion a3 along the first direction U is approximately equal to the dimension C7 of the first connecting line L1 along the first direction U, so that the length of the first edge B5 of the second conductive portion a3 is approximately equal to the length of the third edge B7 of the first connecting line L1, and the length of the second edge B6 of the second conductive portion a3 is approximately equal to the length of the fourth edge B8 of the first connecting line L1.

[0209] Referring to FIG. 17B , since the first edge B5 of the second conductive portion a3 extends beyond the third edge B7 of the first connecting line L1, and the length of the first edge B5 is approximately equal to the length of the third edge B7, the first edge B5 and the third edge B7 do not overlap. During the preparation of the jumper structure T, the wire R does not contact and connect with the first connecting line L1, thereby further reducing the risk of short circuit between the touch electrodes.

[0210] Furthermore, since the second edge B6 of the second conductive portion a3 extends beyond the fourth edge B8 of the first connecting line L1, and the length of the second edge B6 is approximately equal to the length of the fourth edge B8, the second edge B6 and the fourth edge B8 will not overlap. During the preparation of the jumper structure T, the wire R will not contact and connect with the first connecting line L1, thereby further reducing the risk of short circuit between the touch electrodes.

[0211] In some embodiments, as shown in FIG. 16A and FIG. 17A , the first edge B5 of the second conductive portion a3 extends beyond the third edge B7 of the first connection line L1 , and the first edge B5 is substantially parallel to the third edge B7 .

[0212] Through the above-mentioned setting method, the first edge B5 of the second conductive part a3 exceeds the third edge B7 of the first connecting line L1, and the first edge B5 is roughly parallel to the third edge B7, which is beneficial to increasing the length C2 of the outline of the connecting pattern L located between the first connecting line L1 and a second connecting line L2, reducing the risk of short circuit between the first connecting line L1 and the second connecting line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0213] Furthermore, when the length of the first edge B5 is substantially equal to the length of the third edge B7 , it is ensured that the conductive wire R will not contact and connect with the first connecting line L1 , thereby further reducing the risk of short circuit between the touch electrodes.

[0214] In some embodiments, as shown in FIG. 16A and FIG. 17A , the second edge B6 of the second conductive portion a3 exceeds the fourth edge B8 of the first connection line L1 , and the second edge B6 is substantially parallel to the fourth edge B8 .

[0215] Through the above-mentioned setting method, the second edge B6 of the second conductive part a3 exceeds the fourth edge B8 of the first connecting line L1, and the second edge B6 is roughly parallel to the fourth edge B8, which is beneficial to increase the length C2 of the outline of the connecting pattern L located between the first connecting line L1 and a second connecting line L2, reducing the risk of short circuit between the first connecting line L1 and the second connecting line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0216] Furthermore, when the length of the second edge B6 is substantially equal to the length of the fourth edge B8 , it can be ensured that the conductive wire R will not contact and connect with the first connecting line L1 , thereby further reducing the risk of short circuit between the touch electrodes.

[0217] In some embodiments, as shown in Figures 16A and 17A , the first edge B5 of the second conductive portion a3 extends beyond the third edge B7 of the first connection line L1, and the first edge B5 and the third edge B7 are substantially parallel. Furthermore, the second edge B6 of the second conductive portion a3 extends beyond the fourth edge B8 of the first connection line L1, and the second edge B6 and the fourth edge B8 are substantially parallel. This reduces the risk of shorting between the first connection line L1 and the two second connection lines L2, thereby reducing the risk of short circuits between the touch electrodes.

[0218] In some embodiments, as shown in Figures 16A and 17A, the connection pattern L includes two first conductive parts a2, a second conductive part a3 and two second connecting parts a4, one first conductive part a2 is connected to the second conductive part a3 through one second connecting part a4, and the second conductive part a3 is connected to another first conductive part a2 through another second connecting part a4.

[0219] Exemplarily, the second conductive portion a3 and the two second connecting portions a4 form a bridging portion a5 , which crosses the first connecting line L1 , and the first conductive portion a2 passes through the insulating layer 2 b and is connected to the corresponding second connecting line L2 .

[0220] It can be seen that in the design of the jumper structure T, the first edge B5 of the second conductive portion a3 should be ensured to extend beyond the third edge B7 of the first connection line L1, and the second edge B6 of the second conductive portion a3 should be ensured to extend beyond the fourth edge B8 of the first connection line L1.

[0221] As described above, the average distance between the first edge B5 of the second conductive portion a3 and the third edge B7 of the first connection line L1 is D'. Also, the average distance between the second edge B6 of the second conductive portion a3 and the fourth edge B8 of the first connection line L1 is D'.

[0222] Assume that the dimensional tolerance of the second conductive portion a3 along the second direction V is CD1 ′ and the position tolerance of the second conductive portion a3 is OL1 ′.

[0223] Assume that the dimensional tolerance of the first connecting line L1 along the second direction V is CD2 ′, and the position tolerance of the first connecting line L1 is OL2 ′.

[0224] In the case where the vacant area around the mounting hole H is large, the dimensions of the first edge B5 and the second edge B6 of the second conductive portion a3 extending beyond the third edge B7 and the fourth edge B8 of the first connecting line L1 can be set larger, that is, the average distance D' between the first edge B5 and the third edge B7, and the average distance D' between the second edge B6 and the fourth edge B8 can be set larger. Based on this,

[0225] In the case where the vacant area around the mounting hole H is large, the dimensions of the first edge B5 and the second edge B6 of the second conductive portion a3 extending beyond the third edge B7 and the fourth edge B8 of the first connecting line L1 need to be set smaller, that is, the average distance D' between the first edge B5 and the third edge B7, and the average distance D' between the second edge B6 and the fourth edge B8 need to be set smaller. Based on this,

[0226] 18A and 18B are structural diagrams of yet another touch structure according to some embodiments.

[0227] As shown in FIG18A , edge B1 of the first conductive portion a2, which is closer to the first connection line L1, extends beyond edge B2 of the corresponding second connection line L2, which is closer to the first connection line L1. Furthermore, first edge B5 of the second conductive portion a3 extends beyond third edge B7 of the first connection line L1, and second edge B6 extends beyond fourth edge B8 of the first connection line L1. This further increases the length C2 of the outline of the connection pattern L between the first and second connection lines L1, L2.

[0228] Based on this, in the process of preparing the jumper structure T, referring to FIG18B , as the length C2 of the outline of the connection pattern L increases, the length of the wire R increases, and disconnections are more likely to occur in the wire R, thereby reducing the risk of the wire R connecting the first connection line L1 with the second connection line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0229] 19A and 19B are structural diagrams of yet another touch structure according to some embodiments.

[0230] As shown in Figure 19A , an edge B1 of the first conductive portion a2, which is closer to the first connection line L1, extends beyond an edge B2 of the corresponding second connection line L2, which is closer to the first connection line L1. A dimension C3 of each of the two first conductive portions a2 along the first direction U is approximately equal to a dimension C5 of the corresponding second connection line L2 along the first direction U. The first conductive portion a2 and the second connection line L2 form an overlapping double-layer trace.

[0231] Furthermore, the first edge B5 of the second conductive portion a3 exceeds the third edge B7 of the first connecting line L1 , and the second edge B6 of the second conductive portion a3 exceeds the fourth edge B8 of the first connecting line L1 .

[0232] 19B , during the preparation of the jumper structure T, the wire R will not contact and connect with the second connection line L2 , which can further reduce the risk of short circuit between the first connection line L1 and the second connection line L2 , thereby reducing the risk of short circuit between the touch electrodes.

[0233] 20A and 20B are structural diagrams of yet another touch structure according to some embodiments.

[0234] As shown in FIG. 20A , an edge B1 of the first conductive portion a2 on a side close to the first connection line L1 extends beyond an edge B2 of the corresponding second connection line L2 on a side close to the first connection line L1 .

[0235] Furthermore, the first edge B5 of the second conductive portion a3 extends beyond the third edge B7 of the first connecting line L1, and the second edge B6 extends beyond the fourth edge B8 of the first connecting line L1. A dimension C6 of the second conductive portion a3 along the first direction U is substantially equal to a dimension C7 of the first connecting line L1 along the first direction U. Consequently, the second conductive portion a3 and the first connecting line L1 form an overlapping double-layer trace.

[0236] 20B , during the preparation of the jumper structure T, the wire R does not contact and connect with the first connection line L1 , which can further reduce the risk of short circuit between the first connection line L1 and the second connection line L2 , thereby reducing the risk of short circuit between touch electrodes.

[0237] 21A and 21B are structural diagrams of yet another touch structure according to some embodiments.

[0238] In some embodiments, as shown in FIG21A , an edge B1 of the first conductive portion a2 on the side closest to the first connection line L1 extends beyond an edge B2 of the corresponding second connection line L2 on the side closest to the first connection line L1. A dimension C3 of each of the two first conductive portions a2 along the first direction U is substantially equal to a dimension C5 of the corresponding second connection line L2 along the first direction U. The first conductive portion a2 and the second connection line L2 form an overlapping double-layer trace.

[0239] Furthermore, the first edge B5 of the second conductive portion a3 extends beyond the third edge B7 of the first connecting line L1, and the second edge B6 extends beyond the fourth edge B8 of the first connecting line L1. A dimension C6 of the second conductive portion a3 along the first direction U is substantially equal to a dimension C7 of the first connecting line L1 along the first direction U. Consequently, the second conductive portion a3 and the first connecting line L1 form an overlapping double-layer trace.

[0240] 21B , during the preparation of the jumper structure T, the wire R will not contact and connect with the first connection line L1 and the second connection line L2, which can further reduce the risk of short circuit between the first connection line L1 and the second connection line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0241] Furthermore, the jumper structure T can also be applied to the corner region A2 of the display panel 200. For example, the first connecting line L1 in the jumper structure T connects two touch traces, or connects a touch electrode and a touch trace. One of the two second connecting lines L2 connects to a touch electrode or a touch trace, and the other connects to a touch trace. The design of the jumper structure T in the corner region A2 is described below.

[0242] Figure 22 is a structural diagram of a display panel according to some embodiments; Figure 23 is a structural diagram of the display panel in Figure 22 in a corner area; Figure 24 is another structural diagram of the display panel in Figure 22 in a corner area; Figure 25 is yet another structural diagram of the display panel in Figure 22 in a corner area.

[0243] In some embodiments, as shown in FIG. 22 , the touch structure 2 further includes a first routing area BB1 and a second routing area BB2 located on opposite sides of the touch area TA along direction Y, and a third routing area BB3 and a fourth routing area BB4 located on opposite sides of the touch area TA along direction X, for arranging multiple touch routing lines TL.

[0244] The touch lines TL are arranged in the same layer as the touch electrodes, all located in the second conductive layer 2c. The multiple touch lines TL include multiple first touch lines TL1 and multiple second touch lines TL2. Each first touch unit 21 is electrically connected to at least one first touch line TL1. A first touch line TL1 extends from the first wiring area BB1 and extends through the fourth wiring area BB4 to the second wiring area BB2. Each second touch unit 22 is electrically connected to at least one second touch line TL2. A second touch line TL2 extends from the third wiring area BB3 to the second wiring area BB2.

[0245] As shown in Figures 22 and 23, corner area A2 is adjacent to the first routing area BB1 and the third routing area BB3. Among the multiple first touch units 21, the first touch unit 21 closest to the third routing area BB3 includes a first corner touch electrode G1 located in corner area A2. Among the multiple second touch units 22, the second touch unit 22 closest to the first routing area BB1 includes a second corner touch electrode G2 located in corner area A2.

[0246] In the jumper structure T, the first connection line L1 connects the first corner touch electrode G1 and the first touch trace TL1. One of the two second connection lines L2 connects to the second corner touch electrode G2, and the other connects to the second touch trace TL2. The connection pattern L crosses the first connection line L1, and both ends of the connection pattern L pass through the insulating layer 2b and connect to the two second connection lines L2, respectively, thus achieving a normal connection between the second corner touch electrode G2 and the second touch trace TL2.

[0247] It can be understood that, similar to the jumper structure T around the mounting hole H, with reference to Figure 23 , in the jumper structure T in the corner area A2, the spacing between the first connection line L1 and the second connection line L2 is a first dimension C1. In the portion of the connection pattern L between the first connection line L1 and the second connection line L2, the length of the outline from the first connection line L1 to the second connection line L2 is a second dimension C2, and the second dimension C2 is greater than the first dimension C1.

[0248] During the preparation of the jumper structure T, as the length C2 of the outline of the connection pattern L increases, the length of the wire R increases, and disconnections are more likely to occur in the wire R, reducing the risk of the wire R connecting the first connection line L1 and the second connection line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0249] Furthermore, the design of the jumper structure T around the mounting hole H in the aforementioned embodiments is also applicable to the corner area A2 and will not be further described here.

[0250] In some embodiments, as shown in FIG. 24 , the plurality of touch traces TL further include a third touch trace TL3 and a fourth touch trace TL4 .

[0251] In the jumper structure T, the first connecting line L1 connects the first touch line TL1 and the third touch line TL3, which is then connected to the first corner touch electrode G1. One of the two second connecting lines L2 connects to the second touch line TL2, while the other connects to the fourth touch line TL4. The fourth touch line TL4 is then connected to the second corner touch electrode G2. The connection pattern L spans the first connecting line L1, and both ends of the connection pattern L pass through the insulating layer 2b and connect to the two second connecting lines L2, respectively. This ensures a proper connection between the second corner touch electrode G2 and the second touch line TL2.

[0252] In some embodiments, as shown in FIG. 23 , the first connection line L1 and the second connection line L2 are disposed along the outer edge E of the corner area A2 , and the length extension direction of the connection pattern L passes through the corner area A2 .

[0253] As shown in Figure 23, the first corner touch electrode G1 includes a fifth edge B9 close to the outer edge E of the corner area A2. The second corner touch electrode G2 includes a sixth edge B10 close to the outer edge E of the corner area A2. The distance D5 between the fifth edge B9 and the outer edge E of the corner area A2 is less than the distance D6 between the sixth edge B10 and the outer edge E of the corner area A2. The second connection line L2 connected to the second corner touch electrode G2, the first connection line L1, and the second connection line L2 connected to the second touch trace TL2 have decreasing distances from the outer edge E of the corner area A2.

[0254] In some embodiments, as shown in FIG25 , in the jumper structure T, the first connection line L1, the second connection line L2, and the connection pattern L all comprise a metal mesh structure. The metal mesh structure has low resistance and high sensitivity, which improves the efficiency of signal transmission along the first connection line L1, the second connection line L2, and the connection pattern L, thereby enhancing the touch performance of the touch structure 2. Furthermore, the metal mesh structure has high mechanical strength and is lightweight, which helps reduce the weight of the touch structure 2.

[0255] It is understandable that, in the touch structure 2 , the first touch electrodes 210 , the second touch electrodes 220 , the first connecting bridges 211 and the second connecting bridges 221 may all include metal mesh structures.

[0256] In the jumper wire structures Y provided in the above embodiments of the present disclosure, the length C2 of the outline of the connection pattern L between the first connection line L1 and the second connection line L2 is greater than the spacing C1 between the first connection line L1 and the second connection line L2. Compared to jumper wire structures in related arts, the length C2 of the outline of the connection pattern L between the first connection line L1 and the second connection line L2 is increased.

[0257] Furthermore, in the process of preparing the jumper structure T, as the length C2 of the outline of the connection pattern L increases, the length of the wire R increases, and disconnections are easily generated in the wire R, reducing the risk of the wire R connecting the first connection line L1 and the second connection line L2, thereby reducing the risk of short circuit between the touch electrodes.

[0258] The touch structure 2, display panel 200 and display device 100 provided in some embodiments of the present disclosure include the jumper structure T provided in any of the above embodiments. The beneficial effects that can be achieved can refer to the beneficial effects of the jumper structure T above and will not be repeated here.

[0259] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in the present disclosure should be included within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
