Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a folding test jig and a folding test device. BACKGROUND

[0002] With the development of display technology, foldable display devices are becoming a trend in the industry. Foldable display devices can have the advantages of large screen in unfolded state and small structure in folded state.

[0003] Foldable display devices usually include flexible display panels. During the development of the flexible display panels of foldable display devices, folding tests need to be performed multiple times. During the folding tests, the flexible display panels are arranged on folding test jigs, and the folding test jigs are used to switch the flexible display panels between folded and unfolded states.

[0004] However, the folding test jigs in the prior art lack protection design for the bending area of the flexible display panel. Therefore, during the folding test of the flexible display panel, external force introduced due to personnel operation and transportation process, etc. can easily cause damage to the bending area of the flexible display panel. CONTENT OF THE INVENTION

[0005] Therefore, it is necessary to provide a folding test jig and a folding test device capable of providing protection for the bending area of a flexible display panel.

[0006] In a first aspect, an embodiment of the present application provides a folding test jig for supporting a flexible display panel, the flexible display panel including a first non-bending area, a second non-bending area, and a bending area between the first non-bending area and the second non-bending area, the folding test jig comprising:

The second support part is rotated relative to the first support part, so as to drive the bending area to bend, so that the second non-bending area is folded or unfolded relative to the first non-bending area. Since the protective structure is located at the interval between the first support part and the second support part, the projection of the protective structure on the flexible display panel covers at least part of the bending area, so that the protective structure can form a protection on one side of the at least part of the bending area, thereby reducing or avoiding external force acting on the bending area during the bending test.

[0011] In an embodiment, the bending test fixture further comprises at least two groups of hinge assemblies, the first support part and the second support part are rotationally connected through the hinge assemblies, and the at least two groups of hinge assemblies are arranged at intervals along a first direction, the first direction being the rotation axis direction of the second support part.

Detailed Implementation

[0040] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0041] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, this does not indicate any order, quantity, or importance, but is merely used to distinguish different components. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. Words such as “comprising” or “including” mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, without excluding other elements or objects.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] In relevant bending test fixtures, the flexible display panel includes a first non-bending area, a second non-bending area, and a bending area located between the first and second non-bending areas. The bending test fixture includes a first support portion for fixed connection to the first non-bending area and a second support portion for fixed connection to the second non-bending area. The second support portion can rotate relative to the first support portion to cause the second non-bending area to fold or unfold relative to the first non-bending area. To facilitate rotation of the second support portion relative to the first support portion, the second support portion and the first support portion are generally spaced apart, thus exposing the bending area of ​​the flexible display panel to the space between the second and first support portions, resulting in a lack of protection for the bending area. Therefore, during bending tests of the flexible display panel, external forces introduced due to personnel operation and transportation processes act on the bending area of ​​the flexible display panel through the space between the second and first support portions, easily causing damage to the bending area.

[0044] In view of the above problems, embodiments of this application provide a bending test fixture and a bending test device. When performing a bending test on a flexible display panel, a first support portion is fixedly connected to a first non-bending area. A second support portion is fixedly connected to a second non-bending area. By rotating the second support portion relative to the first support portion, the bending area can be bent, causing the second non-bending area to fold or unfold relative to the first non-bending area. Since the protective structure is located at the interval between the first and second support portions, the projection of the protective structure on the flexible display panel covers at least a portion of the bending area, thereby enabling the protective structure to form protection on at least one side of the bending area, thus reducing or avoiding external forces acting on the bending area during the bending test.

[0045] Firstly, please refer to Figure 1 and Figure 2 This application provides a bending test fixture 200 for supporting a flexible display panel 100. The flexible display panel 100 includes a first non-bending area 110, a second non-bending area 120, and a bending area 130 located between the first non-bending area 110 and the second non-bending area 120 (see...). Figure 7 ).

[0046] The bending test fixture 200 includes a first support portion 210, a second support portion 220, and a protective structure. The first support portion 210 is fixedly connected to a first non-bending area 110. The second support portion 220 is fixedly connected to a second non-bending area 120, and the second support portion 220 is spaced apart from the first support portion 210. The second support portion 220 is rotatable relative to the first support portion 210, so that the second non-bending area 120 can be folded or unfolded relative to the first non-bending area 110. The protective structure is located at the interval between the first support portion 210 and the second support portion 220, and the projection of the protective structure on the flexible display panel 100 covers at least a portion of the bending area 130.

[0047] In the aforementioned bending test fixture 200, when performing a bending test on the flexible display panel 100, the first support portion 210 is fixedly connected to the first non-bending area 110. The second support portion 220 is fixedly connected to the second non-bending area 120. By rotating the second support portion 220 relative to the first support portion 210, the bending area 130 can be bent, thereby causing the second non-bending area 120 to fold or unfold relative to the first non-bending area 110. Since the protective structure is located at the interval between the first support portion 210 and the second support portion 220, the projection of the protective structure on the flexible display panel 100 covers at least a portion of the bending area 130, thereby forming protection on at least one side of the bending area 130, thus reducing or avoiding external forces acting on the bending area 130 during the bending test.

[0048] Optionally, the first support portion 210 is fitted to the first non-bending area 110, and the second support portion 220 is fitted to the second non-bending area 120.

[0049] It is understood that when the bending test fixture 200 is in the unfolded state, the flexible display panel 100 is also in the unfolded state, the first non-bending area 110 and the second non-bending area 120 are coplanar, and the first support portion 210, the second support portion 220 and the protective structure are located on the same side of the flexible display panel 100. Optionally, the first support portion 210, the second support portion 220 and the protective structure are all located on the non-display side of the flexible display panel 100. Figures 3 to 5 When the bending test fixture 200 is in the folded state, the first support portion 210 and the second support portion 220 are stacked along their thickness directions. Correspondingly, the first non-bending area 110 and the second non-bending area 120 are stacked along their thickness directions, and the first non-bending area 110 and the second non-bending area 120 are located between the first support portion 210 and the second support portion 220.

[0050] Please refer to Figure 1 and Figure 2 In some embodiments, the bending test fixture 200 includes a hinge assembly 240, through which the first support portion 210 and the second support portion 220 are rotatably connected. Understandably, the hinge assembly 240 is located between the first support portion 210 and the second support portion 220.

[0051] Please refer to Figure 1 and Figure 2 In some embodiments, the bending test fixture 200 includes at least two sets of hinge assemblies 240, and the first support portion 210 and the second support portion 220 are rotatably connected by the hinge assemblies 240. The at least two sets of hinge assemblies 240 are arranged at intervals along a first direction OY. The first direction OY is the direction of the rotation axis of the second support portion 220.

[0052] In this embodiment, by arranging at least two sets of hinge components 240 at intervals along the first direction OY, the first support portion 210 and the second support portion 220 can rotate stably around their respective rotation axes. This avoids the need for a long hinge component on the first direction OY of the bending test fixture 200, thus saving on the cost of the hinge component.

[0053] The number of hinge components 240 can be two, three, or other quantities.

[0054] Please refer to Figure 1 and Figure 2 In some embodiments, a set of hinge components 240 are respectively provided at both ends of the spaced area between the first support portion 210 and the second support portion 220.

[0055] Combined Figures 3 to 5In some embodiments, the protective structure includes a protective rod 250, with both ends of the protective rod 250 connected to two adjacent sets of hinge components 240, and a first support portion 210 and a second support portion 220 spaced apart from the protective rod 250. This allows the protective rod 250 to partially block the bending area 130 along the thickness direction of the flexible display panel, thereby reducing or avoiding external force acting on the bending area 130 during bending tests. The length direction of the protective rod 250 is along the first direction OY. Optionally, the protective rod 250 is a rigid structure.

[0056] In some embodiments, the hinge assembly 240 includes a support member (not shown), a first connector (not shown), and a second connector (not shown). One end of the first connector is rotatably connected to the support member, and the other end of the first connector is connected to the first support portion 210. One end of the second connector is rotatably connected to the support member, and the other end of the second connector is connected to the second support portion 220. Thus, by rotating one end of the first connector relative to the support member and one end of the second connector relative to the support member, the second support portion 220 and the first support portion 210 can be allowed to rotate relative to each other.

[0057] The two ends of the protective rod 250 are respectively connected to the support members of the two adjacent sets of hinge assemblies 240. In this way, during the relative rotation of the first support part 210 and the second support part 220, the protective rod 250 does not affect the relative rotation of the first support part 210 and the second support part 220 and the bending of the bending area 130.

[0058] Combination Figure 5 and Figure 7 In some embodiments, the protective rod 250 is located on the side of the hinge assembly 240 opposite to the bending area 130 of the flexible display panel. Alternatively, the protective rod 250 is located on the side of the support member opposite to the bending area 130 of the flexible display panel.

[0059] Optionally, the first connector is fixedly connected to the first support portion 210, and the second connector is fixedly connected to the second support portion 220.

[0060] Optionally, the first and second connectors are telescopic along their own length. During the relative rotation of the second support 220 and the first support 210, the bending area 130 bends. In this embodiment, both the first and second connectors are telescopic along their own length, so that the telescopic changes of the first and second connectors can adapt to the bending deformation of the bending area 130. The first and second connectors can be telescopic rods, whose lengths can change during telescopic movement.

[0061] Optionally, the support member is provided with a first shaft and a second shaft. One end of the first connecting member has a first sleeve, and one end of the second connecting member has a second sleeve. The first sleeve is rotatably fitted onto the first shaft, and the second sleeve is rotatably fitted onto the second shaft. In this way, the first connecting member can rotate relative to the support member through the cooperation of the first sleeve and the first shaft, and the second connecting member can rotate relative to the support member through the cooperation of the second sleeve and the second shaft.

[0062] In this embodiment, the rotation axis of one end of the first connector is the axis of the first shaft, and the rotation axis of one end of the second connector is the axis of the second shaft.

[0063] In other embodiments, the rotation axis of the first connector and the rotation axis of the second connector may also be the same axis.

[0064] The structure of the hinge assembly 240 is not limited to the above embodiment, and may also be in other forms.

[0065] Combination Figures 5 to 7 Since the first support portion 210 and the second support portion 220 are respectively spaced apart from the protective rod 250, the gap areas between the first support portion 210 and the protective rod 250, and between the second support portion 220 and the protective rod 250, can still expose the bending area 130. That is, the projection of the protective rod 250 onto the flexible display panel 100 covers the bending area 130. Therefore, in some embodiments, the protective structure includes a bendable protective layer 230, which is connected to both the first support portion 210 and the second support portion 220. The bendable protective layer 230 includes a first protective portion 231 and a second protective portion 232, where the first protective portion 231 is located at the gap between the first support portion 210 and the protective rod 250, and the second protective portion 232 is located at the gap between the second support portion 220 and the protective rod 250.

[0066] Thus, the projection of the first protective portion 231 of the bendable protective layer 230 onto the flexible display panel 100 can cover the bending area 130 at the interval between the first support portion 210 and the protective rod 250, and the projection of the second protective portion 232 onto the flexible display panel 100 can cover the bending area 130 at the interval between the second support portion 220 and the protective rod 250, thereby enhancing the protection of the bending area 130 and further reducing or avoiding the application of external force to the bending area 130 during bending tests.

[0067] Optionally, the projection of the first protective portion 231 onto the flexible display panel 100 can cover the entire area of ​​the bending region 130 at the interval between the first support portion 210 and the protective rod 250, and the projection of the second protective portion 232 onto the flexible display panel 100 can cover the entire area of ​​the bending region 130 at the interval between the second support portion 220 and the protective rod 250. In this way, the projections of the protective rod 250, the first protective portion 231, and the second protective portion 232 onto the flexible display panel 100 can cover the entire bending region 130, that is, the projection of the protective structure onto the flexible display panel 100 can completely cover the bending region 130, thus fully enhancing the protection of the bending region 130.

[0068] In other embodiments, the projection of the first protective portion 231 onto the flexible display panel 100 covers a portion of the bending area 130 at the interval between the first support portion 210 and the protective rod 250. The projection of the second protective portion 232 onto the flexible display panel 100 may cover a portion of the bending area 130 at the interval between the second support portion 220 and the protective rod 250.

[0069] In one embodiment, the second direction OX is the direction from the first support portion 210 to the second support portion 220. One end of the first protective portion 231 along the second direction OX is connected to the protective rod 250, and the other end is connected to the first support portion 210. That is, the shielding range of the first protective portion 231 along the second direction OX extends from the first support portion 210 to the protective rod 250, thereby providing relatively comprehensive shielding of the bending area 130 in the interval region between the first support portion 210 and the protective rod 250 along the second direction OX.

[0070] The second protective portion 232 is connected to the second support portion 220 at one end along the second direction OX, and to the protective rod 250 at the other end. That is, the shielding range of the second protective portion 232 along the second direction OX extends from the second support portion 220 to the protective rod 250, thereby providing relatively comprehensive shielding of the bending area 130 in the interval area between the second support portion 220 and the protective rod 250 along the second direction OX.

[0071] Optionally, the first protective portion 231 and the second protective portion 232 are an integral structure, thus the bendable protective layer 230 is a single, integrated structure with good overall integrity. Furthermore, in this embodiment, since the first protective portion 231 and the second protective portion 232 are an integral structure, the bendable protective layer 230's shielding range along the second direction OX continuously extends from the first support portion 210 to the second support portion 220, and extends beyond the protective rod 250, thereby providing relatively comprehensive shielding and protection for the bending area 130.

[0072] The portion of the bendable protective layer 230 that extends beyond the protective rod 250 is located on the side of the protective rod 250 away from the bending area 130. Thus, when assembling the bending test fixture 200, the protective rod 250 can be fixed first, and then the bendable protective layer 230 can be installed, facilitating the secure fixing of the bendable protective layer 230.

[0073] In some embodiments, the bendable protective layer 230 may be made of a flexible material, such as tape. Since a bendable protective layer 230 made of a flexible material is difficult to maintain a fixed shape, the protective rod 250 can provide support for the bendable protective layer 230, facilitating the stabilization of its shape. When the bending test fixture 200 is in the folded state, the support of the protective rod 250 allows the bendable protective layer 230 to remain taut.

[0074] In other embodiments, the protective structure may not include the protective rod 250, but it includes a bendable protective layer 230 connected to the first support portion 210 and the second support portion 220. Thus, the bendable protective layer 230 can at least partially shield the bending area 130 located at the interval between the first support portion 210 and the second support portion 220, reducing or avoiding external forces that the bending area 130 may experience during bending tests.

[0075] In some embodiments, one end of the bendable protective layer 230 covers the side of the first support portion 210 facing away from the first non-bending area 110, and the other end of the bendable protective layer 230 covers the side of the second support portion 220 facing away from the second non-bending area 120. This facilitates the connection between the bendable protective layer 230 and the first support portion 210 and the second support portion 220.

[0076] Optionally, the bendable protective layer 230 is bonded to the first support portion 210, and the bendable protective layer 230 is bonded to the second support portion 220.

[0077] In other embodiments, the bendable protective layer 230 and the first support portion 210 and the second support portion 220 may also be connected in other ways.

[0078] In some embodiments, the bendable protective layer 230 extends continuously from the first support portion 210 to the second support portion 220 along the second direction OX, where the second direction OX is the direction from the first support portion 210 to the second support portion 220. Thus, the bending area 130 is provided with more comprehensive shielding and protection along the second direction OX.

[0079] In some embodiments, the bendable protective layer 230 is made of a flexible material. The bendable protective layer 230, made of a flexible material, can be bent and deformed under external force, and can maintain a fixed shape after bending. Thus, the bendable protective layer 230 not only allows for bending deformation, enabling relative rotation between the second support portion 220 and the first support portion 210 and bending of the bending area 130, but also provides better protection for the bending area 130 by maintaining a fixed shape after bending.

[0080] Optionally, the flexible protective layer 230 may be made of flexible metal or flexible plastic. For example, the flexible protective layer 230 may be made of aluminum sheet, or other plastics with good flexibility.

[0081] like Figure 7 As shown, in some embodiments, when the bending test fixture 200 is unfolded, the bendable protective layer 230 is arc-shaped.

[0082] In some embodiments, the protective structure is spaced apart from the flexible display panel 100, thereby avoiding contact between the protective structure and the flexible display panel 100, specifically avoiding contact with the bending area 130, and thus avoiding unnecessary force exerted by the protective structure on the bending area 130.

[0083] Optionally, the protective rod 250 is spaced apart from the bending area 130 of the flexible display panel 100.

[0084] Optionally, the flexible display panel 100 is provided with bendable protective layer 230 spaced apart between the bendable areas 130.

[0085] Secondly, one embodiment of this application provides a bending test apparatus, including the bending test fixture 200 of any of the embodiments in the first aspect. In the bending test apparatus described above, when performing a bending test on a flexible display panel 100, a first support portion 210 is fixedly connected to a first non-bending area 110. A second support portion 220 is fixedly connected to a second non-bending area 120. By rotating the second support portion 220 relative to the first support portion 210, the bending area 130 can be bent, causing the second non-bending area 120 to fold or unfold relative to the first non-bending area 110. Since the protective structure is located at the interval between the first support portion 210 and the second support portion 220, the projection of the protective structure on the flexible display panel 100 covers at least a portion of the bending area 130, thereby forming protection on at least one side of the bending area 130, thus reducing or avoiding external forces acting on the bending area 130 during the bending test.

[0086] When using the terms “including,” “having,” and “comprising” as described herein, another component may be added unless explicitly qualifying terms such as “only,” “consisting of,” etc. are used. Unless otherwise stated, singular terms may include plural forms and should not be construed as having a quantity of one.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
