[0079] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the present application provides a display panel 10, the display panel 10 has a display area AA and a non-display area NA, and the display panel 10 includes: an array substrate 100; a light-emitting layer 700, the light-emitting layer 700 is arranged on the array substrate 100 and includes a plurality of light-emitting units 710, an isolation structure 500, located in the display area AA, the isolation structure 500 is arranged on the array substrate 100 and has a plurality of isolation openings 500a, and the light-emitting units 710 are located in the isolation openings 500a; a first shielding structure 600, located in the non-display area NA, and the first shielding structure 600 is arranged on the same layer as at least part of the isolation structure 500; a touch component 900, at least part of which is located on a side of the first shielding structure 600 away from the array substrate 100.

[0080] In a display panel 10 provided in an embodiment of the present application, the display panel 10 has a display area AA and a non-display area NA, and the display panel 10 includes an array substrate 100, a light-emitting layer 700, an isolation structure 500, a first shielding structure 600 and a touch component 900. The isolation structure 500 is arranged on the array substrate 100 in the display area AA and is provided with a plurality of isolation openings 500a. The light-emitting unit 710 of the light-emitting layer 700 is arranged in the isolation opening 500a, so that the isolation structure 500 can be used to divide the sub-pixels of the display panel 10.

[0081] The first shielding structure 600 is located in the non-display area NA. By arranging at least part of the touch control assembly 900 on the side of the first shielding structure 600 away from the array substrate 100, the first shielding structure 600 can better limit the signal in the array substrate 100 from being transmitted to the touch control assembly 900, so as to better reduce the mutual interference between the signal in the array substrate 100 and the touch signal in the touch control assembly 900, thereby better improving the working reliability of the display panel 10. In addition, by arranging the first shielding structure 600 and at least part of the isolation structure 500 in the same layer, the first shielding structure 600 can be prepared in the same process step as the isolation structure 500, so that the first shielding structure 600 can be arranged to limit the mutual interference between the touch control signal in the display panel 10 and other signals, and at the same time, the preparation process of the display panel 10 can be simplified, thereby improving the preparation efficiency of the display panel 10.

[0082] There are many ways to set up the array substrate 100. For example, the array substrate 100 may include a substrate 110 and a driving circuit 170 arranged on the substrate 110.

[0083] The touch control assembly 900 may include touch control electrodes and some signal lines connected to the touch control electrodes, for example, a touch control ground signal line, a touch control driving signal line, a touch control receiving signal line, and the like.

[0084] In some embodiments of the present application, the isolation structure 500 may be disposed in the display area AA of the display panel 10, the first shielding structure 600 may be disposed in the non-display area NA of the display panel 10, and the touch component 900 disposed in the non-display area NA and located on the side of the first shielding structure 600 away from the array substrate 100 may be shielded by the first shielding structure 600 and is not likely to interfere with other signals in the display panel 10. For example, the first shielding structure 600 may better shield the driving signal of the driving circuit 170 disposed in the non-display area NA, so that the touch signal of the touch component 900 is not likely to interfere with the driving signal of the driving circuit 170, thereby better improving the working reliability of the display panel 10.

[0085] Optionally, the orthographic projection of a portion of the touch assembly 900 located in the non-display area NA on the array substrate 100 overlaps with the orthographic projection of the first shielding structure 600 on the array substrate 100. Optionally, the orthographic projection of a portion of the driving circuit 170 located in the non-display area NA on the array substrate 100 overlaps with the orthographic projection of the first shielding structure 600 on the array substrate 100. In these optional embodiments, by reasonably setting the relative positional relationship between the first shielding structure 600, the touch assembly 900 and the driving circuit 170, the shielding effect of the first shielding structure 600 can be improved, so as to improve the limiting effect of the first shielding structure 600 on the mutual interference between the touch signal and the driving signal in the display panel 10.

[0086] Optionally, the isolation structure 500 and the first shielding structure 600 are arranged in the same layer and are both integrated structures, so that the first shielding structure 600 can be prepared together with the isolation structure 500 in the same process step to simplify the preparation process of the display panel 10 and improve the preparation efficiency of the display panel 10.

[0087] like Figure 2 As shown, optionally, the isolation structure 500 and the first shielding structure 600 both include a first end 10a facing the array substrate 100 and a second end 10b away from the array substrate 100, the orthographic projection of the first end 10a of the isolation structure 500 on the array substrate 100 is located within the orthographic projection of the second end 10b of the isolation structure 500 on the array substrate 100, and the orthographic projection of the first end 10a of the first shielding structure 600 on the array substrate 100 is located within the orthographic projection of the second end 10b of the first shielding structure 600 on the array substrate 100.

[0088] Optionally, in the direction away from the array substrate 100, the distance between the surfaces of the isolation structure 500 toward the isolation opening 500a on both sides thereof may gradually increase so that the orthographic projection of the first end 10a of the isolation structure 500 on the array substrate 100 is located within the orthographic projection of the second end 10b of the isolation structure 500 on the array substrate 100.

[0089] In these optional embodiments, by setting the orthographic projection of the first end 10a of the isolation structure 500 on the array substrate 100 to be within the orthographic projection of the second end 10b of the isolation structure 500 on the array substrate 100, when the light-emitting layer 700 of the display panel 10 is evaporated, the second end 10b can block at least a portion of the material used to prepare the light-emitting layer 700 to separate the light-emitting layer 700 between adjacent sub-pixels, and can facilitate the formation of a plurality of spaced light-emitting units 710, so that when the light-emitting layer 700 of the display panel 10 is evaporated, there is no need to set a mask with high precision, for example, when the light-emitting layer 700 is evaporated, there is no need to set a high-precision metal mask (Fine Metal Mask, FMM), thereby reducing the production cost of the display panel 10.

[0090] Figure 3 is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application. Figure 4 It is a partial cross-sectional view of a display panel 10 provided in yet another embodiment of the present application.

[0092] The isolation structure 500 includes a first isolation portion 510 and a second isolation portion 520 arranged on the side of the first isolation portion 510 away from the array substrate 100. By setting the orthographic projection of the first isolation portion 510 on the array substrate 100 to be located within the orthographic projection of the second isolation portion 520 on the array substrate 100, when the light-emitting layer 700 and the second electrode layer 800 of the display panel 10 are evaporated, the second isolation portion 520 can block at least part of the material used to prepare the light-emitting layer 700 and the material used to prepare the second electrode layer 800, so as to separate the light-emitting layer 700 and the second electrode layer 800 between adjacent sub-pixels, and can facilitate the formation of a plurality of spaced light-emitting units 710 and the second electrode 810, so that when the light-emitting layer 700 and the second electrode layer 800 of the display panel 10 are evaporated, there is no need to set a mask with high precision, for example, when the light-emitting layer 700 and the second electrode layer 800 are evaporated, there is no need to set a high-precision metal mask, thereby reducing the production cost of the display panel 10.

Figure 8 The dotted outline in FIG. 2 is the structural outline of the second shielding opening 200 a.

[0125] like Figure 7 and Figure 8As shown, in some optional embodiments, the second shielding structure 200 is provided with a plurality of second shielding openings 200a. The second shielding openings 200a can also be used to release the water vapor in the display panel 10, so that the display panel 10 is not easily damaged by the water vapor pressure. For example, the second shielding openings 200a can be used to release the water vapor generated during the re-processing process (such as baking) of part of the organic material layer structure of the display panel 10, and the second shielding openings 200a can also be used to release the water vapor generated in the reliability test of the display panel 10 (such as simulating the user usage scenario).

[0126] Optionally, there are many ways to set the shape of the second shielding opening 200a, wherein the shape of the second shielding opening 200a can be set according to the water vapor discharge requirement in the display panel 10. For example, the shape of the orthographic projection of the second shielding opening 200a on the array substrate 100 can be a polygon, a closed curved shape, or an irregular shape.

[0127] In some optional embodiments, the orthographic projection of the first shielding structure 600 on the array substrate 100 is located within the orthographic projection of the second shielding structure 200 on the array substrate 100, or the orthographic projection of the first shielding structure 600 on the array substrate 100 overlaps with the orthographic projection of the second shielding structure 200 on the array substrate 100.

[0128] By reasonably setting the sizes of the second shielding structure 200 and the second opening, the second shielding structure 200 can have a larger size to limit mutual interference between signals, thereby improving the working reliability of the display panel 10 .

[0129] Optionally, at least a portion of the orthographic projection of the first shielding structure 600 in the thickness direction X of the display panel 10 covers the second shielding opening 200 a .

[0130] Optionally, the orthographic projection of the second shielding opening 200a on the array substrate 100 is spaced from the orthographic projection of the first shielding opening 600a on the array substrate 100. Optionally, the orthographic projection of the second shielding opening 200a on the array substrate 100 is located within at least a portion of the orthographic projection of the first shielding structure 600 on the array substrate 100.

[0131] In these optional embodiments, by reasonably setting the relative position relationship between the second shielding opening 200a and the first shielding opening 600a, in the thickness direction X of the display panel 10, the second shielding structure 200 can better shield the first shielding opening 600a, and the first shielding structure 600 can better shield the second shielding opening 200a, and the touch signal and other signals in the display panel 10 are not likely to interfere with each other through the first shielding opening 600a and the second shielding opening 200a, thereby further improving the working reliability of the display panel 10.

[0132] In some optional embodiments, a plurality of second shielding openings 200 a are arranged at intervals in the first direction Y and / or the second direction Z to enhance the ability of the second shielding openings 200 a to release water vapor.

[0133] In some optional embodiments, there is a preset distance between the orthographic projection of the inner wall of the second shielding opening 200 a on the array substrate 100 and the orthographic projection of the inner wall of the first shielding opening 600 a on the array substrate 100 , and the preset distance is greater than or equal to 20 microns.

[0136] In these optional embodiments, since the preset distance between the first shielding opening 600a and the second shielding opening 200a is too small, for example, when the preset distance is less than 20 micrometers, the touch signal and other signals in the display panel 10 are easy to interfere with each other through the first shielding opening 600a and the second shielding opening 200a that are close to each other, so that the first shielding structure 600 and the second shielding structure 200 cannot effectively limit the mutual interference between the touch signal and other signals in the display panel 10. And when the preset distance between the first shielding opening 600a and the second shielding opening 200a is too large, for example, when the preset distance is greater than 35 micrometers, it is difficult for water vapor to be released through the first shielding opening 600a and the second shielding opening 200a, so that the display panel 10 is easy to be damaged. Therefore, by reasonably setting the relative position relationship between the first shielding opening 600a and the second shielding opening 200a, the touch signal of the display panel 10 and other signals in the display panel 10 are not easy to interfere with each other, and the display panel 10 is not easily damaged by water vapor generated during the preparation or use process, so that the working reliability of the display panel 10 can be well improved.

Optionally, at least part of the second shielding structure 200 is disposed in the same layer as at least part of the power signal line of the display panel 10, and / or at least part of the second shielding structure 200 is disposed in the same layer as at least part of the data signal line of the display panel 10, so that at least part of the second shielding structure 200 can be prepared in the same process step as the power signal line and / or the data signal line, thereby improving the preparation efficiency of the display panel 10.

[0139] For example, the array substrate 100 may further include a fourth insulating layer 150 located on the side of the third insulating layer 140 facing away from the substrate 110, and at least a portion of the second shielding structure 200 may be disposed on the fourth insulating layer 150, and / or, the array substrate 100 may further include a fifth insulating layer 160 located on the side of the fourth insulating layer 150 facing away from the substrate 110, and at least a portion of the second shielding structure 200 may be disposed on the fifth insulating layer 160.
