[0002] With the development of wearable devices and portable electronic products, foldable displays have become increasingly popular due to their unique functionality and portability.

[0051] Example 1
[0052] like Figure 1 The foldable display panel provided in this embodiment includes a foldable display area 100 and a non-foldable display area 200. The foldable display panel includes an anti-crack structure 400 arranged at the edge 300 of the foldable display area. The anti-crack structure 400 includes at least one anti-crack rib 410 and a covering layer 420 covering the anti-crack rib 410.
[0053] like Figure 2 The figure shows a schematic diagram of the cross-sectional structure of the edge of the folding display area of the folding display panel provided in this embodiment. The anti-crack ribs 410 in the cross section of the anti-crack structure 400 are arranged side by side on the substrate of the display panel. Each row of anti-crack ribs 410 is arranged to have at least one layer, and each layer of anti-crack ribs 410 is arranged to have different sizes. Figure 2As shown, the anti-crack structure 400 provided in this embodiment is provided with three rows of anti-crack ribs 410, namely, left, middle and right. The anti-crack ribs 410 in the outermost row are provided with a two-layer structure, each layer is provided with an anti-crack rib 410, and the upper anti-crack ribs 410 and the lower anti-crack ribs 410 are arranged in parallel, but the utility model is not limited thereto. The anti-crack ribs 410 in the middle row can also be replaced and set as a one-layer structure, and the size is slightly smaller than that of the anti-crack ribs 410 in the outermost row. The anti-crack ribs 410 in the innermost row can also be set as a one-layer structure as required, and its size is the same as or slightly smaller than that of the anti-crack ribs 410 in the middle row, and is arranged in parallel with the anti-crack ribs 410 in the middle row. In addition, a covering layer 420 is distributed between and outside each row of anti-crack ribs 410 to fill the gaps between the anti-crack ribs 410, so as to further improve the flexibility and crack resistance of the anti-crack structure 400. In the folding area of the folding display panel, since the number of layers, size and arrangement position of each row of anti-crack ribs 410 are different, the anti-crack structure 400 can effectively disperse stress during the folding process, preventing the folding display panel from cracking and breaking during the folding or unfolding process.
[0054] like Figure 7 The figure is a schematic diagram of the top view of the edge structure of the folding display panel provided in this embodiment, in which the anti-cracking ribs 410 are arranged in parallel in the folding display area 100 and the non-folding display area 200 in the shape of long strips.
[0055] Optionally, the anti-cracking rib 410 has a V-shaped structure in the longitudinal section of the folding display area 100 .
[0056] Optionally, the anti-cracking ribs 410 are configured to have different structures in the folding display area 100 and the non-folding display area 200 .
[0057] Optionally, the width of the anti-crack ribs 410 of the folding display area 100 is smaller than the width of the anti-crack ribs 410 of the non-folding display area 200.

[0059] Optionally, the anti-crack rib 410 is composed of metal or its compound, which has the same composition as the metal or its compound layer of the folding display panel, and is manufactured synchronously using the same process as the folding display panel.

[0061] Optionally, the anti-crack ribs 410 are formed alternately with the covering on the substrate in the up-down direction or the left-right direction.
[0062] Optionally, the anti-crack ribs 410 may be directly accumulated on the substrate and the covering in one direction.
[0063] In this embodiment, the anti-crack ribs 410 structure with multiple rows arranged side by side can effectively disperse and relieve stress concentration in the folding area, reduce stress in the folding area, and thus prevent cracks or damage in the folding area. Different rows of anti-crack ribs 410 can be set with different size specifications, such as thickness, width and other parameters, to further optimize stress distribution and improve anti-crack effect. Covering layers 420 are distributed between and outside each row of anti-crack ribs 410 to fill the gaps between the anti-crack ribs 410, which can further improve the flexibility and crack resistance of the anti-crack structure 400. The anti-crack ribs 410 are arranged in parallel in a long strip shape in the folding display area 100 and the non-folding display area 200, and the longitudinal cross-section of the folding display area 100 can be selected as a V-shaped structure, which can better adapt to the deformation requirements of the folding area. The anti-crack ribs 410 in the folding display area 100 and the non-folding display area 200 can be set to different structures, such as different parameters such as width and height, to meet the anti-crack requirements of different areas. The anti-crack ribs 410 have the same composition as the metal or organic layer of the folding display panel and are simultaneously manufactured using the same process, which can improve manufacturing integration and compatibility.
[0064] In summary, the folding display panel anti-cracking structure 400 provided in this embodiment makes full use of means such as multiple rows side by side, size optimization, and filling of the covering layer 420 to effectively disperse and relieve the stress in the folding area, thereby effectively preventing cracks or damage in the folding area, thereby improving the reliability and service life of the folding display panel.

In this embodiment, the two-layer anti-crack rib 410 structure can also be separately set as one anti-crack rib 410 in the upper layer and two anti-crack ribs 410 in the lower layer, and the upper and lower anti-crack ribs 410 are arranged in parallel and have different sizes, but the utility model is not limited to this. This asymmetric structure of the upper and lower anti-crack ribs 410 can also effectively disperse and relieve the stress concentration of the folding display area 100, and improve the anti-crack effect.
[0072] like Figure 8 The figure shows a schematic diagram of the top view of the edge of the foldable display panel provided in this embodiment. The anti-crack ribs 410 are arranged as left and right bending structures in both the foldable display area 100 and the non-foldable display area 200.
