In one possible implementation manner, when the color of the sub-pixel in the first opening 103 is green and the color of the sub-pixel in the second opening 104 is red or blue in the first display area 100, the human eye is more sensitive to the green color, and when the luminance of the green sub-pixel is the same as that of the sub-pixel in other colors, the human eye is more likely to perceive the green color, so that the distance between the first opening 103 and the first bump structure 106 is smaller than the distance between the second opening 104 and the second bump structure 107, the first bump structure 106 is closer to the first opening 103, the shielding effect of the first bump structure 106 on the sub-pixel in the first opening 103 is larger, the luminance of the green sub-pixel is more greatly reduced, the luminance of the green sub-pixel perceived by the human eye is more consistent with that of the other color sub-pixel, the display uniformity of the first display area 100 and the second display area 200 is improved, and the use experience of the user is improved.

In one possible implementation manner, in the first display area 100, when the color of the sub-pixel in the first opening 103 is green, and the color of the sub-pixel in the second opening 104 is red or blue, the height of the first bump structure 106 may be set to be greater than that of the second bump structure 107, so that the higher bump structure is set near the green sub-pixel, and the higher first bump structure 106 can block the green light emitted from a large angle to a greater extent, reduce the green light brightness to a greater extent, so that the green sub-pixel perceived by the human eye is more consistent with the light emitting brightness of other color sub-pixels, and display consistency of the first display area 100 and the second display area 200 is improved, and use experience of the user is improved.

In addition, the first bump structure 106 has a sidewall facing the first opening 103 and a sidewall facing away from the first opening 103, where the sidewall facing the first opening 103 may perform effects such as reflection and refraction on light emitted by the sub-pixel in the first opening 103, so that the light is blocked, and the sidewall facing away from the first opening 103 does not act on light of the sub-pixel in the first opening 103, so that the inclination degree of the sidewall facing the first opening 103 may be adjusted, so that the light emitting brightness of the sub-pixel in the first display area 100 is adjusted, and the inclination degree of the sidewall facing away from the first opening 103 is not specifically limited herein.

When the side wall of the first protrusion structure 106 facing the first opening 103 is steeper, the side wall facing the first opening 103 has stronger light-emitting shielding effect on the sub-pixels, so that the first angle can be set smaller than the second angle, thus, compared with the light-emitting shielding of the second protrusion structure 107 facing the side wall of the second opening 104 on the red or blue sub-pixels, the light-emitting shielding of the first protrusion structure 106 facing the side wall of the first opening 103 on the green sub-pixels can be stronger, the green light emitted from a large angle is blocked, the green light brightness is reduced to a greater extent, the light-emitting brightness of the green sub-pixels perceived by human eyes is more consistent with the light-emitting brightness of other color sub-pixels, the display uniformity of the first display area 100 and the second display area 200 is improved, and the use experience of users is improved.

The plurality of touch electrode wires 109 can extend along the first direction, a third protruding structure 110 can be arranged between the first opening 103 and the second opening 104, and the third protruding structure 110 also extends along the first direction, so that the edges of the first opening 103 and the second opening 104 can be heightened by the third protruding structure 110, sub-pixel light-emitting in the first opening 103 and the second opening 104 can be shielded, interference of large-angle light-emitting is realized, and therefore the light-emitting brightness of sub-pixels in the first display area 100 is reduced, the difference between the light transmittance of the first display area 100 and the light transmittance of the second display area 200 is reduced, the display consistency of the first display area 100 and the second display area 200 is improved, and the first display area 100 is prevented from being easily visible due to overhigh brightness. Moreover, since the extending direction of the third bump structure 110 is the same as the extending direction of the touch electrode trace 109, the arrangement manner of the third bump structure 110 is the same as the arrangement manner of the touch electrode trace 109, so that the shielding effect of the third bump structure 110 on the luminescence of the sub-pixels in the first display area 100 is the same as the shielding effect of the touch electrode trace 109 on the luminescence of the sub-pixels in the second display area 200, thereby further improving the display consistency of the first display area 100 and the second display area 200.

In one possible implementation manner, the plurality of touch electrode traces 109 may extend along a second direction and a third direction, where the second direction is perpendicular to the third direction, and the second direction is the same as the first direction, as shown in fig. 10, and referring to a top view of still another display panel provided in the embodiment of the present application, the touch electrode traces 109 extend along the second direction and the third direction, so as to form a mesh structure.

The first opening 103 and the second opening 104 are adjacent in the second direction, the third protrusion structure 110 extends in the second direction, the first opening 103 and the third opening 130 are adjacent in the third direction, the fourth protrusion structure 111 is arranged between the first opening 103 and the third opening 130, the fourth protrusion structure 111 extends in the third direction, and thus the third protrusion structure 110 and the fourth protrusion structure 111 are arranged between minimum pitches of the openings and extend in the second direction and the third direction, and are consistent with the extending direction of the touch electrode trace 109, so that the shielding effect of the protrusion structure on the luminescence of the sub-pixels in the first display area 100 is the same as the shielding effect of the touch electrode trace 109 on the luminescence of the sub-pixels in the second display area 200, and the display consistency is improved.

In the first display area 100, a first protrusion structure 106 is provided between the first opening 103 and the second opening 104, the openings located at opposite sides of the first protrusion structure 106 in the AA direction are the first opening 103 and the second opening 104, a distance between the first protrusion structure 106 and the first opening 103 may be denoted as a third distance L3, and a distance between the first protrusion structure 106 and the second opening 104 may be denoted as a fourth distance L4.
