Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a display panel provided in an embodiment of the present application, and fig. 2 is a schematic structural diagram of a substrate provided in an embodiment of the present application. As shown in fig. 1 and fig. 2, the display panel 10 includes a substrate 11, a light emitting structure layer 12 disposed on the substrate 11, and an encapsulation structure layer 13 disposed on the light emitting structure layer 12, wherein the substrate 11 includes an opening region 11A, a spacing region 11B, and a display region 11C, the opening region 11A and the display region 11C are spaced apart by the spacing region 11B, one side of the light emitting structure layer 12 facing away from the substrate 11 protrudes to form at least two circles of banks 121 spaced apart, at least one circle of banks 121 is located on the display region 11C and is disposed around an edge of the spacing region 11B, at least one circle of banks 121 is located on the opening region 11A and is disposed around an edge of the opening region 11A, one side of the light emitting structure layer 12 facing away from the substrate 11 is further recessed to form at least one groove 122, and the groove 122 is located on the spacing region 11B and is disposed around the opening region 11A.
The substrate 11 may be a glass substrate or a hard resin substrate, or may be a flexible substrate used for manufacturing a flexible display panel, and the opening region 121 may be a circular region (as shown in fig. 2), or may have any other planar shape, and is used for mounting a functional device such as a camera, a sensor, or a listening tube lamp. Specifically, as shown in fig. 1, the display panel 10 may further include a mounting hole 14 for the functional device (e.g., a camera), where the mounting hole 14 is located in the middle of the opening region 11A and penetrates through the package structure layer 13 in a direction perpendicular to the substrate 11 while at least partially penetrating through the light emitting structure layer 12. Also, in concrete implementation, the mounting hole 14 may be formed in various shapes according to the design or shape of the functional device to be provided, for example, the mounting hole 14 may be provided so as to have the same width or diameter as that of the functional device, and there is no gap between the side surface of the mounting hole 14 and the side surface of the functional device.
In the present embodiment, since the channel for water and oxygen to enter the display region 11C is formed at the sidewall of the mounting hole 14 of the functional device after the functional device is mounted on the opening region 121, at least one ring of the dam 121 surrounding the edge of the opening region 11A is formed on the opening region 11A, and at least one ring of the dam 121 surrounding the edge of the spacing region 11B is disposed on the display region 11C, so that the dam 121 on the display region 11C and the opening region 11A can perform multiple blocking of water and oxygen on the transmission path of water and oxygen, thereby improving the water and oxygen insulation capability of the display panel 10.
In practical implementation, the dam 121 may be an annular boss, and the longitudinal section of the annular boss may be a closed geometric shape such as a semicircle, a square, or a triangle, and the height of the dam 121 on the display region 11C may be the same as the height of the dam 121 on the opening region 11A, so that the dam 121 can provide support protection for the encapsulation structure layer 13 during the preparation process of the encapsulation structure layer 13, and is beneficial to improving the flatness of the light emitting surface of the display panel 10.
The grooves 122 may be annular grooves, which can extend the path of external water and oxygen permeating from the opening region 11A to the display region 11C, and the larger the number of the grooves 122, the more favorable the water and oxygen isolating capability of the display panel 10 is. In one embodiment, when the number of the grooves 122 is multiple, for example, 8, the multiple grooves 122 may be arranged at equal intervals.

Moreover, it can be understood that, when the process conditions allow, the more the number of steps of the step-shaped surface is, the more the film layer in the packaging structure layer 13 is favorable for forming a uniform film quality on the inner wall of the trench 122, and at the same time, the more the water and oxygen isolation capability is favorable for being improved. In addition, when the number of the grooves 122 is plural, the included angles between the side walls and the bottom wall of the grooves 122 may be the same, for example, all the included angles are obtuse angles, or may be different, and correspondingly, the shapes of the side walls of the grooves 122 may also be the same, for example, all the included angles are double-step shapes, or may be different.
