It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Also, the drawings and description of the embodiments are to be regarded as illustrative in nature, and not as restrictive. Like reference numerals refer to like elements throughout the specification. In addition, the thickness of some layers, films, panels, regions, etc. may be exaggerated in the drawings for understanding and ease of description. It will also be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. In addition, "on … …" means that an element is positioned on or under another element, but does not essentially mean that it is positioned on the upper side of the other element according to the direction of gravity. For ease of understanding, the figures of the present invention depict one element on top of another.
Additionally, unless explicitly described to the contrary, the word "comprise", and variations such as "comprises" or "comprising", will be understood to imply the inclusion of stated elements but not the exclusion of any other elements.
It should also be noted that references to "and/or" in embodiments of the invention are intended to include any and all combinations of one or more of the associated listed items. Various components are described in embodiments of the present invention with "first", "second", "third", and the like, but these components should not be limited by these terms. These terms are only used to distinguish one component from another. Also, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
While certain embodiments may be practiced differently, the specific process sequence may be performed differently than described. For example, two processes described consecutively may be performed at substantially the same time or in an order reverse to that described.
Hereinafter, the structure of the flexible display panel, the flexible display device, and technical effects thereof will be described in detail.
In addition, the following embodiments are all exemplified by the flexible display panel being rectangular, and in practical applications, the flexible display panel may also be regular or irregular, such as circular, polygonal, and the like, and the present invention is not limited to this. Meanwhile, in order to more clearly describe the supporting substrate in the flexible display panel, the following drawings of the embodiments of the present invention correspondingly adjust the size of each structure in the flexible display panel.
Fig. 1 is a schematic cross-sectional structure diagram of a flexible display panel provided by an embodiment of the present invention before being bent. As shown in fig. 1, the flexible display panel includes: a support substrate 10, and a flexible screen 20 disposed on the support substrate 10. Fig. 2 is a schematic top view illustrating a supporting substrate before being bent according to an embodiment of the present invention. As shown in fig. 2, the support substrate 10 includes a non-bending region 11 and at least one bending region 12 (the support substrate 10 includes one bending region 12 is drawn in fig. 2 as an example), the bending region 12 includes a first sub-region 121 and a second sub-region 122, and the first sub-region 121 is located between the second sub-region 122 and the non-bending region 11 and is adjacent to the second sub-region 122 and the non-bending region 11, respectively. The elastic modulus of the first subregion 121 is greater than the elastic modulus of the second subregion 122, and the stiffness of the first subregion 121 is greater than the stiffness of the second subregion 122.
The elastic modulus in the present invention is a physical quantity describing the elasticity of a substance. In the elastic deformation phase, the stress and strain of the material are in a proportional relationship (i.e., according to hooke's law), and the proportionality coefficient is called the elastic modulus (also called young's modulus or bulk modulus). Thus, the modulus of elasticity of the first subregion 121 being greater than the modulus of elasticity of the second subregion 122 can be understood as: the second sub-region 122 is softer and more easily deformed than the first sub-region 121.
Stiffness (which may also be referred to as bending stiffness) in the present invention is a description of the ability of an object to resist its bending deformation. Thus, the stiffness of the first subregion 121 being greater than the stiffness of the second subregion 122 can be understood as: the first sub-region 121 is less likely to bend and has a stronger supporting capability than the second sub-region.
Fig. 3 is a schematic cross-sectional view illustrating a bent flexible display panel according to an embodiment of the present invention. As shown in fig. 3, since the second sub-region 122 is disposed in the bending region, the elastic modulus of the second sub-region 122 is smaller than the elastic modulus of the first sub-region 121, and the elastic modulus of the second sub-region 122 is also smaller than the elastic modulus of the non-bending region, the second sub-region 122 is more easily bent, and can buffer the stress generated when the flexible screen body 20 is bent, so as to reduce the uneven stress when the flexible screen body is bent.
It should be noted that the flexible display panel can be bent from the pre-bent state shown in fig. 1 to the bent state shown in fig. 3 with the aid of a jig or a device, and the bending radius of the flexible display panel can be set according to actual conditions, so the support substrate 10 provided by the present invention can be applied to flexible display panels with any bending radius, and is no longer constrained by the existing SUS with a fixed curved surface form, thereby improving the product applicability.
In addition, when the side of the flexible screen body led out of the FPC corresponds to the bending region shown in fig. 3, the second sub-region 122 with a smaller elastic modulus may provide a space for the FPC, thereby avoiding the problem of interference between the FPC and the support substrate 10.
On the basis of the above embodiments, fig. 4 is a schematic cross-sectional structure diagram of another flexible display panel provided by an embodiment of the present invention before bending; fig. 5 is a schematic top view of another supporting substrate before bending according to an embodiment of the present invention. As shown in fig. 4 and 5, on the basis of the flexible display panel of fig. 1, the bending region 12 further includes: and a third sub-region 123, the second sub-region 122 being located between the first sub-region 121 and the third sub-region 123 and being adjacent to the first sub-region 121 and the third sub-region 123, respectively.
Fig. 6 is a schematic cross-sectional view illustrating a bent flexible display panel according to an embodiment of the present invention. As shown in fig. 6, since the third sub-region 123 is disposed in the bending region, the elastic modulus of the third sub-region 123 is greater than that of the second sub-region 122, and the stiffness of the third sub-region 123 is greater than that of the second sub-region 122. Therefore, the third sub-region 123 at the edge of the flexible display panel can maintain the shape of the flexible display panel frame, and plays a role of support.
With the continuous development of flexible display technology, flexible display panels have been gradually developed from pure curvature to four-sided curvature. In order to implement a four-bend flexible display panel, in an embodiment of the present invention, fig. 7 is a schematic cross-sectional structure diagram of another flexible display panel provided by an embodiment of the present invention before bending. As shown in fig. 7, the flexible display panel includes: a support substrate 10, and a flexible screen 20 disposed on the support substrate 10. Fig. 8 is a schematic top view illustrating a supporting substrate before being bent according to another embodiment of the present invention. As shown in fig. 8, the support substrate 10 includes a non-bending region 11 and four bending regions 12; the non-bending area 11 is rectangular, and the four bending areas 12 are respectively adjacent to four sides of the non-bending area 11; any two adjacent bending areas 12 are not overlapped and have gaps, so that after the bending areas are bent with the aid of a jig or equipment, the two adjacent bending areas 12 are not influenced mutually.
Each bending region 12 includes a first sub-region 121, a second sub-region 122 and a third sub-region 123, and the first sub-region 121 is located between the second sub-region 122 and the non-bending region 11 and is adjacent to the second sub-region 122 and the non-bending region 11, respectively. The second subregion 122 is located between the first subregion 121 and the third subregion 123 and is adjacent to the first subregion 121 and the third subregion 123, respectively.
Fig. 9 is a schematic cross-sectional view illustrating a bent flexible display panel according to an embodiment of the present invention. As shown in fig. 9, the elastic modulus of the first subregion 121 is greater than the elastic modulus of the second subregion 122, and the stiffness of the first subregion 121 is greater than the stiffness of the second subregion 122. The modulus of elasticity of the third subregion 123 is greater than the modulus of elasticity of the second subregion 122, and the stiffness of the third subregion 123 is greater than the stiffness of the second subregion 122. In this way, the first sub-region 121 may realize the transition from the non-bending region 11 to the bending region 12; the second sub-region 122 is easy to bend, and can buffer the stress generated by the flexible screen body 20 when bending, so as to reduce the uneven stress on the flexible screen body when bending; the third sub-area 123 may maintain the shape of the flexible display panel frame, and may serve as a support.
Meanwhile, the flexible display panel shown in fig. 9 can realize the quadric display because the bending regions are arranged on the periphery, and no matter which side of the flexible screen body 20 the FPC is arranged on, the second sub-region 122 can provide a space for the FPC, thereby avoiding the problem of interference between the FPC and the support substrate 10.
In one embodiment, the second sub-region 122 may be a carrier structure or a hinge structure. The carrier tape structure and the hinge structure are easy to bend, and the stress generated when the flexible display panel is bent can be further reduced.
In an embodiment, fig. 10 is a schematic cross-sectional view illustrating a bent flexible display panel according to an embodiment of the present invention. As shown in fig. 10, a buffer 30 is disposed on a side of the third sub-region 123 away from the flexible screen body 20. The buffer part 30 may bind the bent region and the non-bent region after bending.
The material of the buffer portion 30 is at least one of optical adhesive (OCA) and Pressure Sensitive Adhesive (PSA).
Preferably, the cushioning portion 30 is made of a pressure-sensitive adhesive, which is a viscoelastic body having both liquid viscous properties and solid elastic properties, and can be used to bond any smooth surface of an adherend. Therefore, the buffer portion 30 is made of pressure sensitive adhesive, so that the attaching precision can be improved, and the performance of the flexible display panel can be improved.
In one embodiment, the material of the non-bending region 11 is at least one of metal and metal alloy;
the material of the first sub-region 121 is at least one of metal and metal alloy;
the material of the second subregion 122 is at least one of polyethylene terephthalate PET and polyimide PI;
the material of the third subregion 123 is at least one of metal, metal alloy, PET, PI.
In an actual manufacturing process, in order to reduce the difficulty of manufacturing the support substrate 10, the non-bending region 11, the first sub-region 121, and the third sub-region 123 may be made of the same material (such as SUS stainless steel), and the non-bending region 11 and the first sub-region 121 are integrally formed. When the non-bending region 11, the first sub-region 121 and the third sub-region 123 are made of the same material, the elastic modulus of the non-bending region 11, the elastic modulus of the first sub-region 121 and the elastic modulus of the third sub-region 123 are equal; the stiffness of the non-bent area 11, the stiffness of the first sub-area 121 and the stiffness of the third sub-area 123 are equal.
Further, in order to ensure the supporting strength of the non-bending region 11 to the flexible screen body 20 and the bendability of the bending region 12, the thickness of the non-bending region 11 and the thickness of the bending region 12 may be designed. In particular, the thickness of the non-bent region 11 is greater than the thickness of the bent region 12.
Optionally, the thickness of the non-bending region is 1-2 mm; the thickness of the bending area is 0.1-0.2 mm.
Preferably, the thickness of the non-bending zone is 1 mm; the thickness of the bending zone is 0.1 mm.
In addition, it should be noted that the support substrate 10 provided by the present invention can be applied to flexible display panels with any bending radius. The bending radius of the flexible screen body can be set according to actual conditions, and the width of the bending area 12 is positively correlated with the bending radius of the flexible screen body 20.
When the width of the bending region 12 is determined, the width of the first sub-region 121 (or the ratio of the width of the first sub-region 121 in the bending region 12, the ratio of the width of the first sub-region 121 to the width of the bending region 12), the width of the second sub-region 122 (or the ratio of the width of the second sub-region 122 in the bending region 12, the ratio of the width of the second sub-region 122 to the width of the bending region 12), and the width of the third sub-region 123 (or the ratio of the width of the third sub-region 123 in the bending region 12, the ratio of the width of the third sub-region 123 to the width of the bending region 12) may be obtained through simulation.
In one embodiment, the ratio of the width of the first sub-region 121 to the width of the bending region 12 is not greater than 0.5.

The supporting substrate is designed to comprise a non-bending area and at least one bending area, the bending area comprises a first sub-area and a second sub-area, and the second sub-area can greatly relieve stress applied to the flexible screen body when the flexible screen body is bent as the elastic modulus of the first sub-area is greater than that of the second sub-area and the stiffness of the first sub-area is greater than that of the second sub-area; meanwhile, if one side of the flexible screen body, which leads out the FPC, is provided with a bending area, the second sub-area with smaller elastic modulus can provide space for the FPC, and the problem of interference between the FPC and the supporting substrate is prevented.
