Optionally, a signal line of the direct current voltage signal end connected with the second shielding structure 200 may include at least one of an initialization signal line, a negative supply voltage signal line, or a positive supply voltage signal line.
As shown in
Optionally, the shape of the second shielding opening 200a may be set in various manners, in which the shape of the second shielding opening 200a may be set according to the requirement for releasing water vapor in the display panel 10. For example, an orthographic projection of the second shielding opening 200a on the array base plate 100 may be a polygon, a closed curve, or an irregular shape, etc., in shape.
In some optional embodiments, the orthographic projection of the first shielding structure 600 on the array base plate 100 is located within an orthographic projection of the second shielding structure 200 on the array base plate 100, or the orthographic projection of the first shielding structure 600 on the array base plate 100 overlaps the orthographic projection of the second shielding structure 200 on the array base plate.
By suitably setting the sizes of the second shielding structure 200 and the second shielding opening, the second shielding structure 200 can have a larger size to reduce mutual interference between signals, thereby improving the working reliability of the display panel 10.
Optionally, an orthographic projection of at least a portion of the first shielding structure 600 in the thickness direction X of the display panel 10 covers the second shielding openings 200a.
Optionally, the orthographic projection of the second shielding opening 200a on the array base plate 100 is spaced apart from the orthographic projection of the first shielding opening 600a on the array base plate 100. Optionally, the orthographic projection of the second shielding opening 200a on the array base plate 100 is located within an orthographic projection of at least a portion of the first shielding structure 600 on the array base plate 100.
In these optional embodiments, by suitably setting the relative positional 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 block the first shielding opening 600a and the first shielding structure 600 can better block the second shielding opening 200a, so that the touch control signals and other signals in the display panel 10 will not 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.
In some optional embodiments, a plurality of second shielding openings 200a are arranged at intervals in the first direction Y and/or the second direction X, so as to enhance the ability of the second shielding openings 200a to release water vapor.
In some optional embodiments, an orthographic projection of an inner wall of the second shielding opening 200a on the array base plate 100 and an orthographic projection of an inner wall of the first shielding opening 600a on the array base plate 100 is separated by a preset spacing greater than or equal to 20 micrometers.

Optionally, a plurality of first shielding openings 600a may be arranged around a portion of the second shielding openings 200a, and/or a plurality of second shielding openings 200a may be arranged around a portion of the first shielding openings 600a.
In these optional embodiments, if the preset spacing between the first shielding opening 600a and the second shielding opening 200a is too small, and for example, less than 20 micrometers, the touch control signals and other signals in the display panel 10 will interfere with each other through the first shielding opening 600a and the second shielding opening 200a that are close to each other, and thus the first shielding structure 600 and the second shielding structure 200 cannot reduce mutual interference between the touch control signals and other signals in the display panel 10; and if the preset spacing between the first shielding opening 600a and the second shielding opening 200a is too large, and for example, greater than 35 micrometers, water vapor cannot be released through the first shielding opening 600a and the second shielding opening 200a, and thus the display panel 10 will be damaged. Therefore, by suitably setting the relative positional relationship between the first shielding opening 600a and the second shielding opening 200a, the touch control signals of the display panel 10 and other signals in the display panel 10 will not interfere with each other, and moreover, the display panel 10 will not be damaged by water vapor generated in the process of manufacturing or using, thereby further improving the working reliability of the display panel 10.
