Background
The folded display products are gradually mature and are brought to the market. Because the folding product adopts more flexible high polymer materials, such as PET or Polyimide (PI) materials and the like, the high polymer materials can generate creep deformation under the long-term stress in a folding state, thereby generating crease marks or deformation.

The edge of the glass needs to be polished, and different polishing treatments can improve the bending performance of the glass. However, in the process of processing and using the product, the edge of the glass is easy to collide by external force, and due to the characteristic of extremely thin thickness of the foldable glass, the foldable glass is more prone to rupture, so that the product fails.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
Referring to fig. 1 and fig. 2, an embodiment of the present application provides a cover plate structure 100 for protecting a display module 1, including: a flexible cover body 110 and a protective coating 120; the flexible cover plate body 110 comprises a covering structure 111 and a thinning structure 112 located on the periphery of the covering structure 111, the covering structure 111 is located in the middle area of the flexible cover plate body 110, the display area is correspondingly matched with the display module 1, and light transmission can be achieved while the display area is protected. The protective coating 120 is disposed along the edges of the thinned structure 112 and covers at least a portion of the thinned structure 112.
The cover plate structure 100 provided by the embodiment of the application arranges the protective coating 120 at the edge of the thinning structure 112 of the flexible cover plate body 110, and the protective coating 120 at least can coat part of the thinning structure 112, so as to protect the edge of the flexible cover plate body 110, thereby improving the collision resistance effect at the edge of the flexible cover plate body 110, and being beneficial to improving the product strength and the service life of the display module 1 and the corresponding display equipment.
Specifically, the cover plate structure 100 in this embodiment is used for the encapsulation protection of the display module 1, so as to facilitate the installation of the cover plate structure 100, and meanwhile, considering the total thickness of the whole cover plate structure 100, the edge region of the flexible cover plate body 110 needs to be thinned, that is, the thinning structure 112 in this embodiment covers the thinning structure 112, so that the edge of the flexible cover plate body 110 can be protected, and the thickness of the edge of the whole cover plate structure 100 can be controlled.
It is understood that, for the protective coating 120 to cover at least part of the thinned structure 112, only part of the thinned structure 112 may be covered by the protective coating 120, and since the thinned structure 112 is located at the edge region of the flexible cover body 110, the thinned structure 112 covered by the protective coating 120 can perform a protecting and buffering function, thereby reducing the risk of the edge of the flexible cover body 110 being broken as a whole.
In addition, the covering structure 111 and the thinning structure 112 defined in the embodiment of the present application are mainly for convenience of describing the positional relationship of the protective coating 120, and the specific structure and size of the covering structure 111 and the thinning structure 112 are not limited.
Optionally, the material of the flexible cover plate body 110 may be single-layer ultrathin glass, or single-layer or multi-layer flexible polymer film, or a combination material of single-layer or multi-layer flexible polymer film and ultrathin glass, or ultrathin glass with a single-sided or double-sided polymer coating.
Optionally, the protective coating 120 may be made of an organic polymer material such as Polyimide (PI), since PI has better thermal stability and mechanical properties, it can be better combined with the edge of the flexible cover body 110, and can well protect the flexible cover body 110 coated inside the PI. Specifically, the protective coating 120 may be a transparent polyimide or a silicon particle-doped polyimide.
Optionally, the protective coating 120 may also be an ink material with a predetermined color, such as black, white or red ink, so that the protective coating 120 not only serves to protect the edge of the flexible cover body 110, but also serves for ink decoration.
Optionally, the thickness of the protective coating 120 utilizes the natural properties of the solution (e.g., ink material) to slowly level to form a gradual gradient, which is beneficial to the adhesion of the ink material; meanwhile, the optical Adhesive (OCA) can absorb the thickness difference in a fitting manner.
In some embodiments, with continued reference to fig. 1, the projection of the protective coating 120 in the plane of the flexible cover body 110 is a closed loop structure, i.e., the protective coating 120 is disposed along the perimeter of the flexible cover body 110.
Specifically, the thinning structure 112 in the embodiment of the present application is located in the edge region of the flexible cover body 110 (i.e., located at the periphery of the covering structure 111), and in order to further improve the protection of the protective coating 120 on the edge of the flexible cover body 110, the protective coating 120 is fully distributed over the entire peripheral region of the flexible cover body 110, and a closed annular structure is formed, so that the edge of the flexible cover body 110 can be fully protected, and the impact-resistant effect on the edge of the flexible cover body 110 is further improved.
It should be noted that the plane of the flexible cover body 110 is a plane of a figure corresponding to the top view of the flexible cover body 110 in fig. 1.
According to the cover plate structure 100 provided by the embodiment, the protective coating 120 is arranged along the whole edge of the flexible cover plate body 110, so that the edge of the flexible cover plate body 110 can be comprehensively protected, the structural strength of the cover plate structure 100 is improved, and the service life of the cover plate structure is prolonged.
In some embodiments, as shown in fig. 2 and 3, the cross section of the protective coating 120 in the direction perpendicular to the flexible cover body 110 is a U-shaped structure, and the openings of the U-shaped structure face the covering structure 111.
Wherein, the U-shaped structure includes in proper order: the first covering section 121 is positioned on one side of the thinning structure 112 and attached to one side of the thinning structure 112, and the second covering section 122 is positioned on the other side of the thinning structure 112 and attached to the other side of the thinning structure 112; the connecting section 123 is attached to the edge of the thinning-out structure 112 and connects the first covering section 121 and the second covering section 122 to serve as a transition between the first covering section 121 and the second covering section 122.
It is understood that the first cover segment 121, the joining segment 123 and the second cover segment 122 are defined only for convenience of describing a specific structure of the U-shaped structure, which is actually a unitary structure and can be manufactured at the edge region of the flexible cover body 110 through a painting process.
Referring to fig. 1 and 4, in the cover plate structure 100 in fig. 1, a cross section of the protective coating 120 in any direction perpendicular to the flexible cover plate body 110 is a U-shaped structure, so that the thinned structure 112 at the edge of the flexible cover plate body 110 is covered, thereby improving the protective effect on the edge of the flexible cover plate body 110.
Alternatively, the first cover segment 121 and the second cover segment 122 of the U-shaped structure may be symmetrical with respect to the connecting segment 123, and may also be asymmetrical with respect to the connecting segment 123, specifically, whether the slopes of the two sides of the thinning structure 112 of the flexible cover body 110 are symmetrical or not.
Alternatively, as shown in fig. 4 and fig. 5, in consideration of the manufacturing process and the package attachment effect of the protective coating 120, the side of the connecting section 123 of the U-shaped structure away from the thinning structure 112 is in a circular arc structure, that is, the edge of the U-shaped structure is processed into the edge of a rounded corner structure.
Alternatively, as shown in fig. 4 and 5, in order to improve the coating effect of the protective coating 120 and the protective effect of the flexible cover plate body 110, the edge of the thinning structure 112 is processed into the edge of a rounded structure by grinding and polishing, so as to facilitate the coating and manufacturing of the protective coating 120.
Alternatively, the protective coating 120 may be applied by dipping and then cured, or may be applied by double-sided printing, and cured by thermal curing, UV curing, or the like.
In some embodiments, with continued reference to fig. 4 and 5, in order to make the thickness of the edge region (the thinning-out structure 112) of the cover plate structure 100 consistent with the thickness of the middle region (the covering structure 111) as much as possible, the thicknesses of the first covering segment 121 and the second covering segment 122 in the direction perpendicular to the covering structure 111 gradually increase from the end far from the connecting segment 123 to the end near the connecting segment 123.
In this embodiment, because both sides of the thinning structure 112 of the flexible cover plate body 110 have a certain slope, the thickness of the thinning structure 112 along the direction perpendicular to the flexible cover plate body 110 is smaller than the thickness of the covering structure 111 along the direction perpendicular to the flexible cover plate body 110, so as to ensure that the total thickness of the thinning structure 112 after being coated with the protective coating 120 is substantially unchanged. In order to adapt to the gradient of the thinning structure 112 and control the total thickness of the edge of the flexible cover plate body 110, the thickness of the first covering section 121 and the thickness of the second covering section 122 coated with the protective coating are gradually increased from the end far away from the connecting section 123 to the end close to the connecting section 123, so that the thickness of any position in the thinning structure 112 along the direction perpendicular to the flexible cover plate body 110 can be controlled within a relatively consistent range, which is beneficial to the matching installation of the cover plate structure 100, and meanwhile, the structural strength of the edge of the cover plate structure 100 can be ensured.
Alternatively, with continued reference to FIG. 4, the engagement segment 123 of the protective coating 120 can be an arcuate structure, and the thickness of the arcuate structure can be configured to be uniform along any radius.
Alternatively, as shown in fig. 4, the thickness of the covering structure 111 in the direction perpendicular to the flexible cover body 110 (i.e., the thickness of the middle region of the flexible cover body 110) is 5 to 15 micrometers, inclusive.
Optionally, the thickness of the thinning structure 112 and the protective coating 120 covering the thinning structure 112 in a direction perpendicular to the flexible cover body 110 (i.e., the total thickness of the edge region of the flexible cover body 110) is 8 to 20 micrometers, inclusive.
In some embodiments, as shown in fig. 6, in order to further increase the protection effect on the thinning-out structure 112, an end of the first covering segment 121 or the second covering segment 122 away from the connecting segment 123 may extend toward the covering structure 111 and partially cover the covering structure 111. Of course, the first cover segment 121 and the second cover segment 122 may also extend toward the cover structure 111 from the end of the connecting segment 123 and cover a partial area of the cover structure 111.
It should be noted that the coverage areas of the first covering segment 121 and the second covering segment 122 in the covering structure 111 are not too large, so as to avoid affecting the light emission of the display module 1, and the overall thickness of the whole cover plate structure 100 is increased. In addition, for a transparent protective coating, the first cover segment 121 and the second cover segment 122 may extend a little more to the area where the cover structure 111 is located; for opaque protective coatings (e.g., color inks), the first cover segment 121 and the second cover segment 122 generally do not need to extend to the area where the cover structure 111 is located, so as not to affect the normal display of the display module.
The cover plate structure 100 provided by this embodiment ensures that the thinning structure 112 can be completely covered by extending the first covering section 121 and/or the second covering section 122 to the covering structure 111 on each side, thereby increasing the protection effect on the thinning structure 112, and making the edge of the whole cover plate structure 100 more stable when being collided by external force.

In some embodiments, with continued reference to fig. 7, the display module 1 further includes: a support film 400, a flexible display 300, and a functional film 200, which are laminated; the cover structure 100 is disposed on a side of the functional film 200 away from the flexible display 300.
