[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0027] Figure 1 The following is a schematic diagram of the structure of a display panel provided by the prior art. Figure 1As shown, the display panel includes a display area 101 and a non-display area 102, and the non-display area 102 includes a fanout area fanout and a bonding area bonding, and the bonding area bonding is arranged on the side of the fanout area fanout away from the display area 101. The display panel includes an array substrate and a touch substrate arranged in a stacked manner; the array substrate includes a pixel driving circuit layer, a light-emitting display layer and an encapsulation layer, and the pixel driving circuit layer is arranged on one side of the light-emitting display layer, and is used to form a pixel driving circuit and provide a driving signal for the light-emitting display layer. The encapsulation layer is arranged on the side of the light-emitting display layer away from the pixel driving circuit layer, and is used to encapsulate the light-emitting display layer, thereby reducing the probability of the organic light-emitting material in the light-emitting display layer being contaminated by water and oxygen. The encapsulation layer may include an organic material layer, and the array substrate is provided with a dam DAM in the non-display area 102, and the dam DAM is arranged around the display area 101, and is used to prevent the overflow phenomenon of the organic material in the organic material layer. The touch control substrate is arranged on the side of the packaging layer away from the light-emitting display layer. The display area 101 of the touch control substrate is provided with touch control units T arranged in an array. The touch control units T are connected to the bonding terminals of the fan-out area fanout and the bonding area bonding by touch control leads TS to realize the connection between the touch control leads TS and the external driving circuit. When there are more touch control units T, there are more touch control leads TS led to the fan-out area fanout. For example, 600-800 touch control voltages T can be set in a display panel of the size of a mobile phone, and the corresponding touch control leads TS are 600-800. Due to the limitation of the border width of the display panel, the touch lead TS portion led out to the fan-out area fanout cannot be led out vertically. At this time, the touch lead TS has a certain angle with the row direction X' of the display panel, and the extension direction of the dam DAM in the fan-out area fanout is the same as the row direction X' of the display panel. Therefore, the touch lead TS has a certain angle with the dam DAM. Exemplarily, the angle between the touch lead TS and the dam DAM can be less than 20°. Figure 2 The following is a process flow chart of a touch lead provided by the prior art. Figure 2 As shown, in the process of forming the touch lead TS, the array substrate can be used as the substrate of the touch substrate. In the process flow, the substrate is first cleaned (the substrate has a dam DAM), then a touch lead layer is formed by coating, then a photoresist (PR) is coated to form an exposure and development layer, then the exposure and development layer is patterned by exposure and development, so that the pattern of the exposure and development layer is the same as the pattern of the touch lead, then the touch lead layer is patterned by etching to form the touch lead, and finally the exposure and development layer on the touch lead is debonded. Figure 3 A schematic diagram of the cross-sectional structure of a fan-out area before the stripping process is provided in the prior art. Figure 2 and Figure 3As shown, the dam DAM has a certain height. When the angle between the touch lead TS and the dam DAM is relatively small, when the exposure and development layer is patterned by exposure and development, the PR glue will remain at the intersection with the dam DAM ( Figure 2 As a result, the touch lead layer under the residual PR glue is left in the subsequent etching process, which in turn causes the adjacent touch leads formed after etching to be prone to short circuit, thereby reducing the touch reliability of the display panel.

[0028] In view of the above technical problem, an embodiment of the present invention provides a display panel. Figure 4 A schematic diagram of the structure of a display panel provided by an embodiment of the present invention, Figure 5 A schematic diagram of a fan-out area partial blocking structure and a touch signal line structure provided by an embodiment of the present invention. Figure 4 and Figure 5 As shown, the display panel includes a display area 110 and a non-display area 120; the non-display area 120 includes a fan-out area F1, and the fan-out area F1 is provided with a blocking structure 121 and a touch signal line 122; the length extension direction of the vertical projection of at least part of the blocking structure 121 in the thickness direction of the display panel and the extension direction of the vertical projection of the touch signal line 122 in the thickness direction of the display panel have a first angle a, the touch signal line 122 has a second angle b with the first direction X, and the first angle a is greater than the second angle b; wherein the first direction X is the row direction of the display panel.

[0029] Specifically, the display panel may be a touch display panel. The display panel includes an array substrate and a touch substrate. A blocking structure 121 is provided on the array substrate. The blocking structure 121 may be provided around the display area 110 to block the overflow of organic materials in the array substrate. A touch unit and a touch signal line 122 are provided on the touch substrate. The touch signal line 122 extends to the display area 110 through the fan-out area F1, and is connected to the touch unit provided in the display area 110 to provide a path for the touch unit to be connected to an external driving circuit. Along the thickness direction of the display panel, the touch signal line 122 is provided on one side of the blocking structure 121 and crosses the blocking structure 121. Along the viewing angle perpendicular to the thickness direction of the display panel, in the fan-out area F1, the extension direction of the vertical projection of part of the touch signal line 122 in the thickness direction of the display panel has a second angle b with the first direction X; at this time, the length extension direction of the vertical projection of the blocking structure 121 in the thickness direction of the display panel can be set to have an angle with the first direction X, and the angle between the length extension direction of the vertical projection of the blocking structure 121 in the thickness direction of the display panel and the first direction X and the second angle b are respectively located on both sides of the first reference straight line L1. Among them, the first reference straight line L1 is a straight line passing through the intersection of the blocking structure 121 and a touch signal line 122, and extending in the same direction as the first direction X, so that the first angle a between the length extension direction of the vertical projection of the blocking structure 121 in the thickness direction of the display panel and the extension direction of the vertical projection of the touch signal line 122 in the thickness direction of the display panel is greater than the second angle b, thereby increasing the angle at the intersection of the surface where the blocking structure 121 contacts the touch signal line 122 and the touch signal line 122, and further reducing the probability of residual PR glue in the exposure and development process in the process of forming the touch signal line 122, and further reducing the short circuit phenomenon of the touch signal line 122 in the etching process, thereby improving the touch reliability of the display panel.

[0030] It should be noted that the second angle b between different touch signal lines 122 and the first direction X may have different values. In this case, the angles between the length extension direction of the vertical projection of the blocking structure 121 in the thickness direction of the display panel and the first direction X at different positions of the fan-out area F1 may be set to be different according to the second angle b. It is only necessary to satisfy that the first angle a between the blocking structure 121 and the touch signal line 122 is greater than the angle between the length extension direction of the vertical projection of the blocking structure 121 in the thickness direction of the display panel and the first direction X. Exemplarily, when the second angle b between the touch signal line 122 and the first direction X is relatively large, the angle between the blocking structure 121 and the first direction X may be relatively small; when the second angle b between the touch signal line 122 and the first direction X is relatively small, the angle between the blocking structure 121 and the first direction X may be relatively large.

[0031] Based on the above technical solution, the difference between the first angle a and the second angle b is greater than or equal to 5° and less than or equal to 60°.

[0032] Specifically, the difference between the first angle a and the second angle b is the angle between the vertical projection length of the blocking structure 121 in the thickness direction of the display panel and the first direction X. Figure 4 and Figure 5 , along the first direction X, the included angle between the extending direction of the vertical projection of the touch signal line 122 in the thickness direction of the display panel and the first direction X gradually increases until the included angle with the first direction X is 90°, and then gradually decreases. Therefore, along the first direction X, the included angle between the extending direction of the vertical projection of the touch signal line 122 arranged on both sides of the fan-out area F1 in the thickness direction of the display panel and the first direction X is the smallest, and the included angle between the extending direction of the vertical projection of the touch signal line 122 arranged in the middle in the thickness direction of the display panel and the first direction X is the largest. Along the column direction of the display panel, the fan-out area F1 has a certain width. The angle between the extension direction of the vertical projection of the touch signal line 122 arranged on both sides of the fan-out area F1 in the thickness direction of the display panel and the first direction X is generally greater than 25°. By setting the difference between the first angle a and the second angle b to be greater than or equal to 5°, the angle between the length extension direction of the vertical projection of the blocking structure 121 in the thickness direction of the display panel and the extension direction of the vertical projection of the touch signal line 122 in the thickness direction of the display panel can be greater than or equal to 30°. In this way, in the process of forming the touch signal line 122, the probability of residual PR glue in the exposure and development process can be reduced, thereby reducing the short circuit phenomenon of the touch signal line 122 in the etching process, thereby improving the touch reliability of the display panel. Similarly, the maximum angle between the extension direction of the vertical projection of the touch signal line 122 arranged in the middle in the thickness direction of the display panel and the first direction X is 90°. By setting the difference between the first angle a and the second angle b to be less than or equal to 60°, it can also be ensured that the angle between the length extension direction of the vertical projection of the blocking structure 121 in the thickness direction of the display panel and the extension direction of the vertical projection of the touch signal line 122 in the thickness direction of the display panel is greater than or equal to 30°, thereby reducing the probability of residual PR glue in the exposure and development process in the process of forming the touch signal line 122.

[0033] Figure 6 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, Figure 7 A schematic diagram of the extending direction of a blocking structure in a second region and a touch signal line in an adjacent first region provided by an embodiment of the present invention. Figure 6 and Figure 7As shown, the fan-out area F1 includes a first area D1 and a second area D2 which are alternately arranged, and the touch signal line 122 is arranged in the first area D1; an extension direction of the length of the vertical projection of the blocking structure 121 arranged in the first area D1 in the thickness direction of the display panel and an extension direction of the vertical projection of the touch signal line 122 in the thickness direction of the display panel have a first angle a, and an extension direction of the length of the vertical projection of the blocking structure 121 arranged in the second area D2 in the thickness direction of the display panel and an extension direction of the vertical projection of the touch signal line 122 in the adjacent first area D1 in the thickness direction of the display panel have a third angle c; wherein the third angle c is less than or equal to 10°.

[0034] Specifically, the fan-out region F1 can be divided into at least one first region D1 and at least one second region D2. When the first region D1 and / or the second region D2 include at least two, the first region D1 and the second region D2 can be arranged at intervals. The touch signal line 122 is arranged in the first region D1, and the length extension direction of the vertical projection of the blocking structure 121 in the thickness direction of the display panel and the extension direction of the vertical projection of the touch signal line 122 in the thickness direction of the display panel have a first angle a, which can increase the angle between the surface where the blocking structure 121 contacts the touch signal line 122 and the touch signal line 122 at the intersection, and thus in the process flow of forming the touch signal line 122, the probability of residual PR glue in the exposure and development process can be reduced. The length extension direction of the vertical projection of the blocking structure 121 arranged in the second area D2 in the thickness direction of the display panel and the extension direction of the vertical projection of the touch signal line 122 in the adjacent first area D1 in the thickness direction of the display panel have a third angle c. At this time, the angle between the length extension direction of the vertical projection of the blocking structure 121 arranged in the second area D2 in the thickness direction of the display panel and the first direction X, and the angle between the length extension direction of the vertical projection of the blocking structure 121 in the first area D1 in the thickness direction of the display panel and the first direction X are respectively located on both sides of the second reference straight line L2, wherein the second reference straight line L2 is a straight line passing through the point where the blocking structure 121 in the first area D1 and the blocking structure 121 in the second area D2 intersect, and the extension direction is perpendicular to the first direction X. The extending direction of the blocking structure 121 in the second area D2 is bent from the end of the blocking structure 121 in the first area D1 close to the second area to the direction away from the display area, which can reduce the space occupied by the blocking structure 121 in the column direction of the display panel and reduce the probability of the blocking structure 121 in the fan-out area F1 extending to the display area 110. Moreover, the third angle c is less than or equal to 10°, and the extending direction of the blocking structure 121 in the second area D2 can be set to be bent as much as possible from the end of the blocking structure 121 in the first area D1 close to the second area to the direction away from the display area, so as to reduce the space occupied by the blocking structure 121 in the column direction of the display panel as much as possible, so as to reduce the probability of the blocking structure 121 extending to the display area 110 when the second area D2 is relatively small, and increase the area of ​​the first area D1 on the basis of a certain fan-out area F1, so as to facilitate the setting of more touch signal lines 122 and improve the touch accuracy of the display panel. Or increase the spacing between the touch signal lines 122 to further reduce the phenomenon of short circuit of the touch signal lines 122.

[0035] It should be noted that the touch signal line 122 can be arranged only in the first area D1, so as to avoid the phenomenon that when the touch signal line 122 is arranged in the second area D2, the angle between the blocking structure 121 in the second area D2 and the touch signal line 122 in the second area D2 is relatively small, which easily causes the touch signal line 122 to short-circuit. In addition, the extension directions of the touch signal lines 122 in different first areas D1 are different, and the extension direction of the blocking structure 121 in the second area D2 only needs to be compared with the extension direction of the touch signal line 122 in the adjacent first area D1. When the second area D2 is provided with adjacent first areas D1 on both sides along the first direction X, the touch signal line 122 in any adjacent first area D1 can be selected as a reference.

[0036] Continue to refer Figure 6 and Figure 7 The length extension direction of the vertical projection of the blocking structure 121 disposed in the second area D2 in the thickness direction of the display panel is parallel to the extension direction of the vertical projection of the touch signal line 122 in the adjacent first area D1 in the thickness direction of the display panel.

[0037] Specifically, when the length extension direction of the vertical projection of the blocking structure 121 in the second area D2 in the thickness direction of the display panel is parallel to the extension direction of the vertical projection of the touch signal line 122 in the adjacent first area D1 in the thickness direction of the display panel, the extension direction of the blocking structure 121 in the first area D1 is corrected by the blocking structure 121 in the second area D2. Along the first direction X, the space occupied by the blocking structure 121 in the next first area D1 in the column direction of the display panel can have an overlapping area with the space occupied by the blocking structure 121 in the previous first area D1 in the column direction of the display panel, thereby further reducing the space occupied by the blocking structure 121 in the column direction of the display panel and avoiding the blocking structure 121 in the fan-out area F1 from extending to the display area 110.

[0038] Continue to refer Figure 6 and Figure 7 The fan-out area F1 includes a plurality of alternately arranged first areas D1 and second areas D2, the blocking structure 121 in the first area D1 is connected to the blocking structure 122 in the second area D2, and the blocking structure 121 in the fan-out area F1 extends in a broken line along the first direction X.

[0039] Specifically, the fan-out region F1 may include a plurality of first regions D1 and a plurality of second regions D2, and the first regions D1 and the second regions D2 are alternately arranged. In the first region D1 and the second region D2, the blocking structure 121 extends in straight lines respectively, which can reduce the length of the blocking structure 121; at the same time, the extending direction of the blocking structure in the first region is opposite to the extending direction of the blocking structure in the second region, which can ensure the angle between the blocking structure 121 and the touch signal line 122, and avoid the situation where the angle between the local blocking structure 121 and the touch signal line 122 is relatively small. When the blocking structures 121 in the first region D1 and the second region D2 are both straight lines, and the extending direction of the blocking structure in the first region is opposite to the extending direction of the blocking structure in the second region, the blocking structure 121 in the first region D1 and the blocking structure 122 in the second region D2 are connected, so that the blocking structure 121 in the fan-out region F1 extends in a broken line. In addition, the blocking structure 121 in the first region D1 is connected to the blocking structure 121 in the second region D2 , which can ensure the continuity of the blocking structure 121 in the fan-out region F1 , thereby ensuring that the blocking structure 121 can block the overflow of the organic material.

[0040] It should be noted that, continue to refer to Figure 6 , the display panel includes a display area 110 and a non-display area 120; the non-display area 120 includes a fan-out area F1, and the fan-out area F1 is provided with a blocking structure 121 and a touch signal line 122; the length extension direction of at least part of the blocking structure 121 in the thickness direction of the display panel and the extension direction of the vertical projection of the touch signal line 122 in the thickness direction of the display panel have a first angle a, the touch signal line 122 has a second angle b with the first direction X, and the first angle a is equal to the second angle b; wherein the first direction X is the row direction of the display panel. That is, the difference between the first angle and the second angle is zero. When the extension direction of the touch signal line 122 is perpendicular to the first direction X, the extension direction of the blocking structure 121 can be set to be parallel to the first direction X, that is, the angle between the touch signal line 122 and the blocking structure 121 can be ensured to be relatively large, which improves the short circuit phenomenon between adjacent touch signal lines 122 that is easily caused when making the touch signal line 122, and improves the touch reliability of the display panel.

[0041] Optionally, the touch signal line 122 extending in a direction perpendicular to the first direction may be disposed in a third region (not marked in the figure), the third region being located between adjacent first regions, or between adjacent first and second regions; or the sector-shaped area only has the third region.

[0042] Optionally, along the first direction X, the straight lines formed by the starting points of the blocking structures 121 in different first regions D1 extend in parallel with the first direction X, and the straight lines formed by the end points of the blocking structures 121 in different first regions D1 extend in parallel with the first direction X.

[0043] Specifically, when the blocking structure 121 in the fan-out area F1 extends in a folded line, the extension direction of the straight line formed by the starting points of the blocking structures 121 in different first areas D1 can be set to be parallel to the first direction X, and the extension direction of the straight line formed by the end points of the blocking structures 121 in different first areas D1 can be set to be parallel to the first direction X, so that the connection line of the highest point of the folded line presented by the blocking structure 121 in the fan-out area F1 is parallel to the first direction X, and the connection line of the lowest point is parallel to the first direction X, so that the blocking structures 121 in different first areas D1 occupy the same space in the column direction of the display panel, further reducing the space in the column direction of the display panel required by the blocking structure 121, and preventing the blocking structure 121 in the fan-out area F1 from extending to the display area 110. At the same time, the continuity of the blocking structure 121 in the fan-out area F1 can be ensured while reducing the length of the blocking structure 121.

[0044] Continue to refer Figure 6 and Figure 7 The first area D1 and the second area D2 include overlapping side edges D11 , the side edges D11 have an angle with the first direction X, and the extending direction of the side edges D11 is the same as the extending direction of the touch signal lines 122 in the adjacent first area D1 .

[0045] Specifically, the side D11 of the first area D1 and the second area D2 can be divided according to the extension direction of the touch signal line 122. That is, the side D11 of the first area D1 and the second area D2 is parallel to the extension direction of the touch signal line 122 in the adjacent first area D1. Among them, when the side D11 where the first area D1 and the second area D2 overlap is located on the left side of the second area D2 along the first direction X, the adjacent first area D1 of the side D11 is the first area D1 located on the left side and adjacent to the second area D2. At this time, the extension direction of the side D11 is the same as the extension direction of the touch signal line 122 in the first area D1 adjacent to the left side of the second area D2. When the side D11 where the first area D1 and the second area D2 overlap is located on the right side of the second area D2 along the first direction X, the adjacent first area D1 of the side D11 is the first area D1 located on the right side and adjacent to the second area D2. At this time, the extension direction of the side D11 is the same as the extension direction of the touch signal line 122 in the first area D1 adjacent to the right side of the second area D2. Exemplarily, the first area D1 and the second area D2 may be trapezoidal. When the extension direction of the touch signal line 122 in the first area D1 adjacent to the side D11 of the second area has an angle with the column direction of the display panel, the side D11 of the first area D1 and the second area D2 have the same angle with the column direction of the display panel, which can reduce the required width of the touch signal line 122 in the first area D1 and the touch signal line 122 in the second area D2 along the first direction X, and can reduce the free space of the first area D1 and the second area D2 in the first direction X relative to when the first area D1 and the second area D2 are rectangular, thereby improving the utilization of the first area D1 and the second area D2.

[0046] In other embodiments, optionally, the first area includes at least two touch signal lines, and within the first area, an extension direction of a vertical projection of each touch signal line in the thickness direction of the display panel is equal to a first angle between an extension direction of a vertical projection of the blocking structure in the thickness direction of the display panel and a length.

[0047] Specifically, in the same first area, when the angle between the extension direction of the blocking structure and the first direction remains unchanged, the angle between the extension direction of each touch signal line and the first direction can be set unchanged, so that the extension direction of the vertical projection of each touch signal line in the thickness direction of the display panel and the first angle between the length extension direction of the vertical projection of the blocking structure in the thickness direction of the display panel can be equal to each other, which is beneficial to ensure that the angle between the surfaces where different touch signal lines contact the blocking structure and the touch signal lines at the intersection is relatively large, thereby reducing the probability of residual PR glue in the exposure and development process. In addition, when the angle between the extension direction of different touch signal lines in the same first area and the first direction changes (for example, along the first direction, the width of the first area close to the display area is greater than the width of the first area away from the display area, and at this time, the angle between the extension direction of different touch signal lines in the same first area and the first direction can be set to change), the extension direction of the blocking structure in the same first area can be set to change according to the extension direction of the touch signal line intersecting with it, so that the extension direction of the vertical projection of each touch signal line in the thickness direction of the display panel and the first angle of the length extension direction of the vertical projection of the blocking structure in the thickness direction of the display panel are equal, to ensure that the angle between different touch signal lines and the surface of the blocking structure at the intersection is relatively large, thereby reducing the probability of residual PR glue in the exposure and development process.

[0048] Based on the above technical solutions, along the first direction, the distance from the side of the second region to the blocking structure in the second region is greater than zero and less than the width of the blocking structure in the second region, wherein the width of the blocking structure in the second region is the width along the first direction.

[0049] Specifically, along the first direction, the distance from the side of the second region to the blocking structure in the second region is greater than zero, so as to ensure that the blocking structure is arranged in the second region. At the same time, the distance from the side of the second region to the blocking structure in the second region is less than the width of the blocking structure in the second region, so as to avoid wasting space in the fan-out region due to setting the width of the second region too large. Optionally, on the basis of ensuring that the second region accommodates the blocking structure, the distance from the side of the second region to the blocking structure in the second region can be set to be slightly greater than the setting error, so as to ensure that the position of the blocking structure is located in the second region when there is an error, and at the same time, to avoid wasting space in the fan-out region as much as possible.

[0051] Specifically, by providing a blocking structure 121 in the first sub-region A1, the second sub-region A2, the third sub-region A3 and the fan-out region F1, and the blocking structures 121 in the first sub-region A1, the second sub-region A2, the third sub-region A3 and the fan-out region F1 are connected to each other, the blocking structure 121 can be arranged around the display area 110, so that the organic material extending into the display area 110 can be blocked in all directions.

[0052] Continue to refer Figure 8 The non-display area 120 further includes a bonding area B1 , which is disposed on a side of the fan-out area F1 away from the display area 110 .
