For example, referring to fig. 7, the opening pattern 130 is a plurality of openings arranged in an array, and the plurality of openings have a rectangular shape.

In some examples, referring to fig. 4, fig. 4 is a block diagram of the location a in fig. 3. The opening pattern 130 includes a first opening pattern 131, and the first opening pattern 131 covers at least the first edge portion 110.

The first opening pattern 131 may be one opening, or may be a plurality of openings arranged in an array, and the plurality of openings may be any one of rectangular, semicircular, semi-elliptical, trapezoidal, and triangular, and of course, the plurality of openings may also be other irregular shapes.

In this embodiment, by at least disposing the first opening pattern 131 at the first edge 110 of the support layer 13, the bending stress of the flexible display panel 100 at the first edge 110 can be reduced, the bending and folding performance of the flexible display panel 100 can be improved, and the first edge 110 can be better attached to the contour 214.

Based on this, for example, please continue to refer to fig. 4, the orthographic projection of the first opening pattern 131 on the flexible display panel 100 is also located in an area d1 of the flexible display panel 100 close to the first edge portion 110. That is, the first opening pattern 131 includes a portion located in the first edge region 110 and a portion beyond in the area d1 in the first edge region 110.

Some embodiments of the present disclosure provide a display assembly 200, which includes a portion located in the first edge portion 110 and a portion located beyond the region d1 in the first edge portion 110, by providing the first opening pattern 131 on the support layer 13 of the flexible display panel 100, the first opening pattern 1311 enables better bending performance of the first edge portion 110 of the flexible display panel 100, and thus enables better fitting of the first edge portion 110 and the contour 214.

In some examples, the dimension beyond the area d1 in the first edge region 110 is between 2mm and 7 mm. For example, it may be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, or the like.

In this example, when the size of the area d1 beyond the first edge portion 110 is equal to or close to 2mm, the bending performance of the flexible display panel 100 at the first edge portion 110 can be improved to some extent, and at the same time, the arrangement area of the first opening patterns 131 is made smaller, and the support layer 13 is better used for supporting the flexible display panel 100, so that the overall structural strength of the flexible display panel 100 is higher. When the size of the area d1 beyond the first edge 110 is equal to or close to 7mm, the bending performance of the flexible display panel 100 at the first edge 110 can be greatly improved, and the flexible display panel 100 can be supported to a certain extent because the arrangement area of the first opening pattern 131 is not too large, thereby ensuring the overall structural strength of the flexible display panel 100.

Based on this, for example, please continue to refer to fig. 5, the orthographic projection of the second opening pattern 132 on the flexible display panel 100 is also located in an area d2 of the flexible display panel 100 near the scrolling region 120. That is, the second opening pattern 132 includes a portion located in the slider roll region 120 and a portion in the area d2 beyond the slider roll region.

In some examples, the area d2 beyond the slider region has a dimension of 2mm to 7 mm. For example, it may be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, or the like.

In this example, when the size of the area d2 beyond the slider roll area is equal to or close to 2mm, the bending performance of the flexible display panel 100 at the position of the slider roll area 120 can be improved to some extent, and at the same time, the arrangement area of the second opening patterns 132 is made smaller, and the support layer 13 is better used for supporting the flexible display panel 100, so that the overall structural strength of the flexible display panel 100 is higher. When the size of the area d2 beyond the scrolling region is equal to or close to 7mm, the bending performance of the flexible display panel 100 at the scrolling region 120 can be greatly improved, and the flexible display panel 100 can be supported to a certain extent because the arrangement area of the second opening pattern 132 is not too large, thereby ensuring the overall structural strength of the flexible display panel 100.
