Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.

Although relative terms, such as "upper" and "lower," may be used in this specification to describe one element of an icon relative to another, these terms are used in this specification for convenience only, e.g., in accordance with the orientation of the examples described in the figures. It will be appreciated that if the device of the icon were turned upside down, the element described as "upper" would become the element "lower". When a structure is "on" another structure, it may mean that the structure is integrally formed with the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via another structure.

The terms "a," "an," "the," "said," and "at least one" are used to indicate the presence of one or more elements/components/parts/etc.; the terms "comprising" and "having" are intended to be inclusive and mean that there may be additional elements/components/etc. other than the listed elements/components/etc.

The embodiment of the application provides a supporting structure which can be applied to a flexible display panel. Specifically, this bearing structure can set up the one side at flexible display panel to provide certain support for flexible display panel, thereby can improve flexible display panel's roughness, and strengthen flexible display panel's shock resistance, resistant bending property.

For example, the supporting structure may be disposed on a back surface of the flexible display panel, where the back surface refers to a surface opposite to the display surface of the flexible display panel; but not limited thereto, the supporting structure may also be disposed on the display surface of the flexible display panel, and at this time, the supporting structure needs to be transparent, so as to provide support for the flexible display panel and avoid affecting normal display. In addition, when the supporting structure is arranged on the display surface of the flexible display panel, the supporting structure can also be matched with the requirement of touch control.

It should be understood that, in order to satisfy the supporting performance of the supporting structure, the supporting structure may be made of a material having a certain thickness and rigidity, for example, a metal material, etc., but is not limited thereto.

Because bearing structure has certain thickness and rigidity, leads to it to buckle the performance relatively poor, consequently, is unfavorable for matching less bending radius's demand, and is unfavorable for dispersing the stress that produces when buckling to lead to the structure in the flexible display panel to take place to damage under the stress action easily, lead to the condition that display performance reduces then.

To improve this, the support structure may be designed in zones. Specifically, the supporting structure may include a bendable region and a fixed region, wherein a bending axis corresponding to the bendable region extends in a first direction, and the fixed region is located on two opposite sides of the bendable region in a second direction, which means that the second direction intersects with the first direction, that is, the fixed region does not affect the bendable region to bend or curl; optionally, the second direction is orthogonal to the first direction.

It should be understood that the bendable region of the support structure needs to be opposite to the bendable region of the flexible display panel, and when the bendable region of the flexible display panel is bent or curled, the bendable region of the support structure is also bent or curled along with the bendable region of the flexible display panel; the fixing region of the supporting structure is opposite to the fixing region of the flexible display panel, and the fixing region needs to be fixed in the process of bending or curling the flexible display panel provided with the supporting structure, so that the bendable region can be bent or curled, or the bending or curling state of the bendable region can be maintained.

Based on the above situation, in order to improve the bending performance of the bendable region in the support structure and facilitate matching the requirement of a smaller bending radius, in the design process, the rigidity of the bendable region needs to be designed to be smaller, which refers to the capability of resisting deformation; meanwhile, in order to ensure the supporting stability of the supporting structure, the stability of the overall shape of the supporting structure and reduce the processing deformation, the rigidity of the fixing region needs to be designed to be larger, that is, the rigidity of the whole fixing region in the supporting structure should be larger than that of the bendable region.

In addition, since the whole supporting structure is usually made of the same metal material, that is, the material of the fixed region and the material of the bendable region in the supporting structure are the same, different patterning processes can be performed on the fixed region and the bendable region to achieve the purpose of different rigidities.

In order to make the rigidity of the bendable region smaller than that of the fixed region, the whole bendable region can be subjected to open-hole patterning treatment, and the fixed region is not subjected to patterning treatment; namely: a plurality of first hollow holes are formed in the whole bendable area of the formed supporting structure, and the fixing area does not have the hollow holes; however, the difference between the rigidity of the fixed region and the bendable region is too large, so that the junction between the fixed region and the bendable region has large rigidity jump, and the junction between the fixed region and the bendable region has large rigidity jump.

Furthermore, in order to eliminate or weaken the situation that the rigid mutation occurs at the junction between the fixed region and the bendable region, the whole bendable region is subjected to the open-cell patterning treatment, so that the whole bendable region is provided with a plurality of first hollow holes, and meanwhile, the open-cell patterning treatment can be further performed on a part of the structure connected with the bendable region in the fixed region, so as to reduce the rigidity of the part of the structure in the fixed region, and the part of the structure can be defined as a buffer part, namely: the buffer part can be provided with a plurality of second hollow holes. The rigidity of the buffer part can be slightly larger than or equal to that of the bendable area so as to eliminate or weaken the condition of rigidity mutation at the junction of the fixed area and the bendable area.

In addition, in order to ensure the overall stability and the processing accuracy of the supporting structure, in the design process, the fixing region not only includes the buffer portion, but also includes a rigid retaining portion, and at least part of the rigid retaining portion is arranged on one side of the buffer portion away from the bendable region; wherein, the rigidity of this rigidity holding portion is greater than the rigidity of buffer to can guarantee that the holistic rigidity of fixed area is greater than the rigidity of the district of can buckling, like this improve the flexible performance in the district of can buckling among the bearing structure, when doing benefit to the demand of matcing less radius of buckling, still can guarantee bearing structure's support stability, the stability of the whole shape of bearing structure and reduce the processing deformation.

It should be understood that the rigid holding portion may be a portion of the fixing region that is not patterned, but is not limited thereto, and the rigid holding portion may be patterned to a certain degree as long as the rigidity of the rigid holding portion is ensured to be greater than that of the cushioning portion, and the entire support structure can satisfy the above requirements.

The following provides a detailed description of the support structure of various embodiments of the present application with reference to the drawings.
