Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As an alternative implementation of the disclosure, an embodiment of the present application discloses a flexible cover plate, as shown in fig. 1 and fig. 2, fig. 1 is a schematic top view of the flexible cover plate according to the embodiment of the present application, and fig. 2 is a schematic cross-sectional structure of the flexible cover plate along a cutting line AA' shown in fig. 1, where the flexible cover plate includes an elastic layer 10 and a supporting layer 11 disposed on one side of the elastic layer 10.
The elastic layer 10 is a film layer having an elastic restoring force greater than a predetermined value. The elastic restoring force refers to a restoring force of the elastic body after deformation due to an external force, and the larger the elastic restoring force is, the larger the probability of restoring the film layer after deformation is. After the flexible cover plate is stretched, the elastic layer 10 is not easy to creep, and the supporting layer 11 can be driven to recover quickly, so that the stretching recovery capacity of the flexible cover plate can be improved, and the stretching effect of the display panel can be improved.
Preferably, the elastic layer 10 comprises a super elastic layer having an elastic restoring force of greater than 99%. Preferably, the material of the super elastic layer includes at least one of a rubber-based super elastic material, a gel-based super elastic material, and a polyurethane-based super elastic material. Preferably, the material of the superelastic layer comprises polydimethylsiloxane or thermoplastic vulcanizate.
The support layer 11 includes support portions 110 and elastic portions 111 arranged in a first direction. The first direction intersects the thickness direction of the elastic layer 10. The first direction may be an X direction or a Y direction shown in fig. 1, where the X direction is the same as a long side extending direction of the flexible cover plate, and the Y direction is the same as a short side extending direction of the flexible cover plate.
Preferably, the support layer 11 includes at least two support portions 110 and at least one elastic portion 111.
The supporting portion 110 has a structure with a certain hardness, which not only can support the elastic layer 10, but also can enable the flexible cover plate to have a certain mechanical property, and further enable the flexible cover plate to have a certain impact resistance and damage resistance. Preferably, at least two support portions 110 are arranged at least in the first direction. Preferably, the first direction is parallel to the plane of the elastic layer 10. Preferably, the material of the support part 110 is polyimide or the like.
The elastic portion 111 has a structure having a certain elasticity, and a stretchable amount thereof is larger than that of the supporting portion 110. Preferably, at least one elastic part 111 is located at least between two adjacent support parts 110 in the first direction, the elastic part 111 is used to connect the two adjacent support parts 110 and attach the support parts 110 to one side of the elastic layer 10.
Although the stretching amount of the supporting portion 110 is small, the stretching amount of the elastic portion 111 is large, so that not only the stretching amount of the whole supporting layer 11 in the first direction can be increased by the elastic portion 111 between two adjacent supporting portions 110, but also the stretching amount of the flexible cover plate in the first direction can be increased, and the supporting portion 110 can be quickly restored by the elastic portion 111, so that the stretching recovery capability of the flexible cover plate can be improved, and the stretching effect of the display panel can be improved. In addition, since the elastic portion 111 can make the supporting portion 110 attached to the elastic layer 10, the elastic layer 10 can drive the elastic portion 111 and the supporting portion 110 to recover quickly, so that the stretching recovery capability of the flexible cover plate can be further improved, and the stretching effect of the display panel can be further improved.
In some embodiments of the present application, as shown in fig. 2, each elastic portion 111 is located between two adjacent support portions 110.
