[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] In addition, this application may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0041] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0042] The first aspect of the present application provides a folding support assembly, such as Figure 1 and Figure 2 As shown, the folding support assembly is used to support the flexible display module 400. The flexible display module 400 includes a first non-bending area Q1, a second non-bending area Q2, and a bending area Q3 located between the first non-bending area Q1 and the second non-bending area Q2. The folding support assembly includes:

[0043] A first fixing frame 110 is used to support the first non-bending area Q1;

[0044] The second fixing frame 120 is used to support the second non-bending area Q2;

[0045] The first sliding frame 210 is slidably connected to the first fixed frame 110 so that the first sliding frame 210 slides in the first non-bending area Q1 and the bending area Q3;

[0046] The second sliding frame 220 is slidably connected to the second fixed frame 120 so that the second sliding frame 220 slides in the second non-bending area Q2 and the bending area Q3; and

[0047] The hinge module 300 is connected to the first sliding frame 210 and the second sliding frame 220 respectively, so that the hinge module slides in the bending area Q3.

[0048] In the folding support assembly of this embodiment, as Figure 1 and Figure 2 As shown, the first sliding frame 210 and the second sliding frame 220 connected on both sides of the hinge module 300 are slidably connected to the first fixed frame 110 and the second fixed frame 120 respectively. The sliding connection between the first sliding frame 210 and the first fixed frame 110 can enable the first sliding frame 210 to slide in the first non-bending area Q1 and the bending area Q3. Similarly, the sliding connection between the second sliding frame 220 and the second fixed frame 120 can enable the second sliding frame 220 to slide in the second non-bending area Q2 and the bending area Q3, thereby enabling the hinge module 300 to slide in the bending area Q3, so that it can be bent at any position in the bending area Q3 through the hinge module 300, so that the folding display panel has more diverse folding display ratios to meet the user's diverse folding display ratio requirements.

[0049] In the folding support assembly of this embodiment, as Figure 1 and Figure 2 As shown, the flexible display module 400 includes a first non-bending region Q1, a bending region Q3, and a second non-bending region Q2, which are connected in sequence. The first non-bending region Q1 is disposed on and supported by the first fixed frame 110, and the second non-bending region Q2 is disposed on and supported by the second fixed frame 120. A sliding portion, comprising the first sliding frame 210, the hinge module 300, and the second sliding frame 220, slides as a whole under the support and guidance of the first and second fixed frames 110, 120. During the sliding process, a portion of the sliding portion always corresponds to the position of the bending region Q3, thereby providing support for the bending region Q3. At the same time, the hinge module 300 slides in the bending area Q3 and always corresponds to the position of the bending area Q3. The bending area Q3 can be folded through the hinge module 300, and the specific position of the hinge module 300 in the bending area Q3 can be adjusted by the overall sliding of the sliding part, thereby adjusting the folding position of the bending area Q3 to present different folding display ratios.

[0050] In the folding support assembly of this embodiment, the hinge module 300 can adopt either an external folding hinge module 300 or an internal folding hinge module 300. Those skilled in the art can make an adaptive choice according to design requirements, which will not be elaborated here.

[0051] In the folding support assembly of this embodiment, as Figure 1 and Figure 2As shown, the folding support assembly is symmetrical with the hinge module 300 as the axis, and the structures of the second fixed frame 120 and the second sliding frame 220 are symmetrical with the structures of the first fixed frame 110 and the first sliding frame 210, respectively. Their structures and working principles are the same as those of the first fixed frame 110 and the first sliding frame 210. In the following embodiments of the present application, the design structure and working principle of the first fixed frame 110 and the first sliding frame 210 are used as examples. The understanding of the second fixed frame 120 and the second sliding frame 220 can refer to the description of the first fixed frame 110 and the first sliding frame 210, and the same parts will not be repeated.

[0052] As an optional implementation, Figure 3 As shown, a plurality of first fixed frame bars 111 are provided at intervals in the first fixed frame 110, and a first slide 112 is formed between two adjacent first fixed frame bars 111; a plurality of first sliding frame bars 211 are provided at intervals in the first sliding frame 210, and the first sliding frame bars 211 are slidably set in the corresponding first slide 112; a plurality of second fixed frame bars 121 are provided at intervals in the second fixed frame 120, and a second slide is formed between two adjacent second fixed frame bars 121; a plurality of second sliding frame bars 221 are provided at intervals in the second sliding frame 220, and the second sliding frame bars 221 are slidably set in the corresponding second slide.

[0053] In the folding support assembly of this embodiment, as Figure 3 and Figure 8 As shown, the first fixed frame 110 is provided with a plurality of first fixed frame bars 111 at intervals. These first fixed frame bars 111 form a support surface on the side of the first fixed frame 110 for supporting the first non-bending region Q1. Accordingly, the first sliding frame bars 211 are provided with a plurality of first sliding frame bars 211 at intervals. These first sliding frame bars 211 form a support surface on the side of the first sliding frame 210 for supporting the bending region Q3. The first fixed frame bars 111 are spaced apart, thereby forming a first slideway 112 between adjacent first fixed frame bars 111. Accordingly, the first sliding frame bars 211 are spaced apart so that the first slideway bars 211 and the first fixed frame bars 111 are arranged in an alternating pattern. This allows all the sliding frame bars in the first sliding frame 210 to be positioned in corresponding first slideways 112, allowing the first sliding frame bars 211 to slide within the corresponding first slideways 112, thereby achieving a sliding connection between the first sliding frame 210 and the first fixed frame 110. The sliding connection method of the second sliding frame 220 and the second fixed frame 120 is the same as the sliding connection method of the first sliding frame 210 and the first fixed frame 110 , and will not be repeated here.

[0054] In the folding support assembly of this embodiment, as Figure 8As shown, based on the staggered arrangement of the comb teeth of the first sliding frame bar 211 and the first fixed frame bar 111, the first sliding frame 210 can slide relative to the first fixed frame 110, and the support planes formed by the first sliding frame bar 211 and the first fixed frame bar 111 are respectively located in the same horizontal plane, and the first sliding frame bar 211 and the first fixed frame bar 111 still form a support plane located in the same horizontal plane after being staggered, so that the support for the first non-bending area Q1 and the bending area Q3 is always located in the same horizontal plane, and the support effect on the first non-bending area Q1 and the bending area Q3 will not be affected by the relative sliding of the first sliding frame 210 and the first fixed frame 110. Similarly, based on the staggered arrangement of the comb teeth of the second sliding frame bar 221 and the second fixed frame bar 121, the second sliding frame 220 can slide relative to the second fixed frame 120, and the support planes formed by the second sliding frame bar 221 and the second fixed frame bar 121 are respectively located on the same horizontal plane, and the second sliding frame bar 221 and the second fixed frame bar 121 still form a support plane located on the same horizontal plane after being staggered, so that the support for the second non-bending area Q2 and the bending area Q3 is always located on the same horizontal plane, and the support effect on the second non-bending area Q2 and the bending area Q3 will not be affected by the relative sliding of the second sliding frame 220 and the second fixed frame 120.

[0055] In the folding support assembly of this embodiment, as Figure 1 and Figure 2 As shown, the size of the gap between two adjacent first fixed frame bars 111 is preferably such that it does not affect the supporting effect on the first non-bending area Q1 and does not affect the sliding of the first sliding frame 210 on the first fixed frame 110. Correspondingly, the size of the gap between two adjacent first sliding frame bars 211 is preferably such that it does not affect the supporting effect on the bending area Q3 and does not affect the sliding of the first sliding frame 210 on the first fixed frame 110. If the gap between two adjacent first fixed frame bars 111 is too large, or the gap between two adjacent first sliding frame bars 211 is too large, the support for the flexible display panel at the gap is weak, which can easily cause the flexible display panel to deform and affect its display effect; if the gap between two adjacent first fixed frame bars 111 is too small, or the gap between two adjacent first sliding frame bars 211 is too small, then the same flexible display panel size requires a larger number of first fixed frame bars 111 and first sliding frame bars 211, and the sliding contact area between the first fixed frame bar 111 and the second sliding frame bar 221 is too large, resulting in greater sliding resistance, which affects the sliding of the first sliding frame 210 on the first fixed frame 110. The design principles for the gap size between two adjacent first fixed frame bars 111 and the gap size between two adjacent first sliding frame bars 211 are the same and will not be repeated here.

[0056] As an optional implementation, Figures 4 to 9As shown, the first fixed frame bar 111 is provided with a first limiting groove 113 on the side facing the first slide 112; accordingly, the first sliding frame bar 211 is provided with a first limiting protrusion 212 matching the first limiting groove 113 on the side facing the first fixed frame bar 111; the second fixed frame bar 121 is provided with a second limiting groove on the side facing the second slide, and the second sliding frame bar 221 is provided with a second limiting protrusion matching the second limiting groove on the side facing the second fixed frame bar 121.

[0057] In the folding support assembly of this embodiment, as Figures 8 to 10 As shown, the first limiting protrusion 212 of the first sliding frame bar 211 is placed in the first limiting groove 113 of the first fixed frame bar 111. The first limiting groove 113 can limit the movement of the first sliding frame bar 211 in the thickness direction of the folding support assembly, thereby preventing the first sliding frame bar 211 from falling off the first slide 112 during sliding, and ensuring that the support plane formed by the first sliding frame bar 211 and the first fixed frame bar 111 remains horizontal. The second limiting protrusion in the second sliding frame bar 221 and the second limiting groove in the second fixed frame bar 121 work in the same way and will not be described in detail here.

[0058] In the folding support assembly of this embodiment, as Figure 4 and Figure 6 As shown, the first limiting groove 113 is a rectangular groove, and correspondingly, the first limiting protrusion 212 is a rectangular protrusion matching the rectangular groove.

[0059] In other embodiments, the first limiting groove 113 may also be a trapezoidal groove or other structure that limits the first limiting protrusion 212 from escaping therefrom. Those skilled in the art may select a suitable first limiting groove 113 structure and a matching first limiting protrusion 212 structure based on the difficulty of assembly, manufacturing cost, etc., which will not be elaborated here.

[0060] In the folding support assembly of this embodiment, it should be noted that Figure 2 and Figure 8 As shown, one side surface of the first fixed frame strip 111 located at the edge of the first fixed frame 110 does not intersect with the first sliding frame strip 211, so there is no need to provide the first slideway 112 there, and accordingly, there is no need to provide the first limiting groove 113. The side structure of the first fixed frame strip 111 located at the edge of the first fixed frame 110 can be designed accordingly according to the design requirements of the foldable display panel, and will not be further described here.

[0061] As an optional implementation, Figures 4 to 10As shown, at least one first fixed frame bar 111 is provided with a plurality of first positioning grooves 114 on the side facing the first slide 112 or the first limiting groove 113 is provided with a plurality of first positioning grooves 114, and the corresponding first sliding frame bar 211 is provided with a retractable first positioning member 213 on the side facing the first positioning groove 114 or the first limiting protrusion 212 is provided with a retractable first positioning member 213 on the side facing the first positioning groove 114, and the first positioning member 213 can be accommodated in the first positioning groove 114 after being extended; at least one second fixed frame bar 121 is provided with a plurality of second positioning grooves on the side facing the second slide or the second limiting groove is provided with a plurality of second positioning grooves, and the corresponding second sliding frame bar 221 is provided with a retractable second positioning member on the side facing the second positioning groove or the second limiting protrusion is provided with a retractable second positioning member on the side facing the second positioning groove, and the second positioning member can be accommodated in the second positioning groove after being extended.

[0062] In the folding support assembly of this embodiment, the first sliding frame bar 211 and the first fixed frame bar 111 are positioned by placing the first positioning member 213 in a positioning groove, thereby ensuring the stability of the folding support assembly and facilitating folding through the hinge module 300.

[0063] In the folding support assembly of this embodiment, as Figure 4 and Figure 5 As shown, a plurality of first positioning grooves 114 are provided in the first limiting groove 113 of the first fixing frame bar 111. Figure 6 and Figure 7 As shown, a retractable first positioning member 213 is provided on the first limiting protrusion 212 of the first sliding frame bar 211. As the first sliding frame bar 211 slides relative to the first fixed frame bar 111 in the first slideway 112 / first limiting groove 113, the first positioning member 213 successively passes through the first positioning grooves 114 at different positions. When the first positioning member 213 passes through a particular positioning groove 114, it extends and is accommodated in that first positioning groove 114. At this time, the structure of the folding support assembly is relatively more stable, and the stability of folding via the hinge module is also relatively better. When the first positioning member 213 passes through other positions in the first slideway 112 / first limiting groove 113, the first positioning member 213 retracts to allow the first sliding frame bar 211 to slide smoothly in the first slideway 112 / first limiting groove 113.

[0064] In the folding support assembly of this embodiment, as Figure 4 and Figure 5As shown, five first positioning grooves 114 are sequentially provided in the first limiting groove 113 of the first fixed frame bar 111. Accordingly, the first sliding frame bar 211 can be positioned in these five first positioning grooves 114 when sliding in the first limiting groove 113. Accordingly, the hinge module 300 has five folding positions in the bending area Q3. When folded at these five positions, the structural stability of the folding display module is better.

[0065] In the embodiment, the number and positions of the first positioning grooves 114 provided on the first fixing frame bar 111 can be adaptively selected according to the size of the bending area Q3 , which will not be described in detail here.

[0066] In the folding support assembly of this embodiment, as Figure 6 and Figure 7 As shown, the first positioning member 213 on the first limiting protrusion 212 of the first sliding frame bar 211 is preferably arranged at the end of the first sliding frame bar 211 that is always located in the first slide 112 to ensure that the first positioning member 213 escapes from the first slide 112 and cannot be positioned.

[0067] In the folding support assembly of this embodiment, as Figure 8 As shown, two first fixed frame bars 111 can be selected from the first fixed frame 110 to set the first limiting groove 113 , and accordingly, two first sliding frame bars 211 can be selected from the corresponding positions in the first sliding frame 210 to set the first positioning member 213 .

[0068] In the folding support assembly of other embodiments, the number of first fixed frame bars 111 provided with the first positioning groove 114 can be adaptively selected according to design requirements. For example, a first fixed frame bar 111 can be selected from the first fixed frame 110 to be provided with the first limiting groove 113, and accordingly, a first sliding frame bar 211 at the corresponding position in the first sliding frame 210 is selected to be provided with the first positioning member 213. For another example, all first fixed frame bars 111 in the first fixed frame 110 are provided with the first limiting groove 113, and accordingly, all first sliding frame bars 211 at the corresponding position in the first sliding frame 210 are provided with the first positioning member 213. In addition, the first positioning groove 114 can be provided on only one side of the first fixed frame bar 111, or on both sides of the first fixed frame bar 111; accordingly, the first positioning member 213 in the first sliding frame bar 211 can be adaptively adjusted.

[0069] As an optional implementation, Figure 10As shown, a first mounting hole 214 is provided on the first sliding frame bar 211, a first elastic member 215 is provided in the first mounting hole 214, and the first positioning member 213 is accommodated in the first mounting hole 214 by compressing the first elastic member 215; a second mounting hole is provided on the second sliding frame bar 221, a second elastic member is provided in the second mounting hole, and the second positioning member is accommodated in the second mounting hole by compressing the second elastic member.

[0070] In this embodiment, the folding is in the support assembly, such as Figure 10 As shown, by setting the first elastic member 215 in the first mounting hole 214, the first positioning member 213 compresses the first elastic member 215 and places it in the first mounting hole 214, and the compression deformation of the first elastic member 215 provides the first positioning member 213 with a telescopic function. Figure 11 and Figure 12 As shown, when the first positioning member 213 passes through the first positioning groove 114, the first elastic member 215 pops out the first positioning member 213 so that the first positioning member 213 can be accommodated in the first positioning groove 114; when the first positioning member 213 passes through other positions in the first limiting groove 113, the first positioning member 213 is squeezed and contracted into the first mounting hole 214, so that the first sliding frame bar 211 can slide smoothly in the first slide 112.

[0071] As an optional implementation, Figures 10 to 12 As shown, the portion of the first positioning member 213 extending from the first mounting hole 214 is hemispherical, and the first positioning groove 114 is a hemispherical groove; the portion of the second positioning member extending from the second mounting hole is hemispherical, and the second positioning groove is a hemispherical groove.

[0072] In the folding support assembly of this embodiment, by making the part of the first positioning member 213 extending out of the first mounting hole 214 into a hemispherical shape, and correspondingly making the first positioning groove 114 into a hemispherical groove, the first positioning member 213 of the hemispherical structure can more easily slide from the first positioning groove 114 of the hemispherical structure.

[0073] As an optional implementation, Figure 1 and Figure 2 As shown, the sum of the length of the first sliding frame bar 211 and the width of the hinge module 300 is greater than or equal to the length of the bending zone Q3; the sum of the length of the second sliding frame bar 221 and the width of the hinge module 300 is greater than or equal to the length of the bending zone Q3.

[0074] In the folding support assembly of this embodiment, as Figure 1 and Figure 2As shown, the sliding distance of the first sliding frame bar 211 in the first slide 112 is less than or equal to the length of the first sliding frame bar 211, and the sliding distance of the second sliding frame bar 221 in the second slide is less than or equal to the length of the second sliding frame bar 221. At the same time, considering that the width of the hinge module 300 occupies a certain space, the sum of the length of the first sliding frame bar 211 and the width of the hinge module 300 is greater than or equal to the length of the bending zone Q3; the sum of the length of the second sliding frame bar 221 and the width of the hinge module 300 is greater than or equal to the length of the bending zone Q3, which can ensure that when the first sliding frame bar 211, the second sliding frame bar 221 and the hinge module 300 slide synchronously, the sliding range of the hinge module 300 is greater than or equal to the bending zone Q3, so that the hinge module 300 can traverse the bending zone Q3 by sliding, so that the bending zone Q3 has more folding positions through the hinge module 300.

[0075] As an optional implementation, Figure 1 and Figure 2 As shown, the length of the first fixed frame bar 111 is greater than or equal to the first sliding frame bar 211 ; the length of the second fixed frame bar 121 is greater than or equal to the second sliding frame bar 221 .

[0076] In the folding support module of this embodiment, Figure 1 and Figure 2 As shown, the sliding distance of the first sliding frame bar 211 in the first slideway 112 is less than or equal to the length of the first sliding frame bar 211, and the sliding distance of the second sliding frame bar 221 in the second slideway is less than or equal to the length of the second sliding frame bar 221. By making the length of the first fixed frame bar 111 greater than or equal to the first sliding frame bar 211, and the length of the second fixed frame bar 121 greater than or equal to the second sliding frame bar 221, the sliding of the first sliding frame bar 211 in the first fixed frame bar 111 within its own length is not restricted by the length of the first fixed frame bar 111. Correspondingly, the sliding of the second sliding frame bar 221 in the second fixed frame bar 121 within its own length is not restricted by the length of the second fixed frame bar 121.

[0077] As a further preferred embodiment, the length of the first sliding frame bar 211 is greater than the length of the bending zone Q3; the length of the second sliding frame bar 221 is greater than or equal to the length of the bending zone Q3.

[0078] In the folding support module of this embodiment, the sliding distance of the first sliding frame bar 211 in the first slide 112 is less than or equal to the length of the first sliding frame bar 211, and the sliding distance of the second sliding frame bar 221 in the second slide is less than or equal to the length of the second sliding frame bar 221. By making the length of the first fixed frame bar 111 greater than or equal to the first sliding frame bar 211, the length of the second fixed frame bar 121 greater than or equal to the second sliding frame bar 221, and further making the length of the first sliding frame bar 211 greater than the length of the bending area Q3, and the length of the second sliding frame bar 221 greater than or equal to the length of the bending area Q3, when the sliding part composed of the first sliding frame 210, the second sliding frame 220 and the hinge module 300 slides synchronously, it can be ensured that the first sliding frame bar 211 and the first fixed frame bar 111 always have an interlaced area, and at the same time, the second sliding frame bar 221 and the second fixed frame bar 121 always have an interlaced area. The interlaced area can improve the stability of the folding support module and prevent the first sliding frame bar 211 from escaping from the first slide 112 and the second sliding frame bar 221 from escaping from the second slide.

[0079] Based on the same inventive concept, the second aspect of the present application also proposes a foldable display panel, such as Figure 1 and Figure 2 As shown, the folding display panel includes the above-mentioned folding support assembly and a flexible display module 400. The flexible display module 400 includes a first non-bending area Q1, a second non-bending area Q2, and a bending area Q3 located between the first non-bending area Q1 and the second non-bending area Q2. The first non-bending area Q1 is fixed to the first fixed frame 110 through an adhesive layer, and the second non-bending area Q2 is fixed to the second fixed frame 120 through an adhesive layer.

[0080] Since the folding display panel provided by the present invention includes the folding support assembly of the above technical solution, the folding display panel provided by the present invention has all the beneficial effects of the above folding support assembly, which will not be described in detail here.

[0081] In this embodiment of the foldable display panel, the first non-bending region Q1 is fixed to the first fixed frame 110 via an adhesive layer, thereby securing the first non-bending region Q1 relative to the first fixed frame 110 and enabling the first fixed frame 110 to support the first non-bending region Q1. Similarly, by securing the second non-bending region Q2 to the second fixed frame 120 via an adhesive layer, the second non-bending region Q2 is secured relative to the second fixed frame 120 and enabling the second fixed frame 120 to support the second non-bending region Q2. No adhesive layer is provided between the bending region Q3 and the first sliding frame 210, the second sliding frame 220, and the hinge module 300 for securing. This allows the first sliding frame 210, the second sliding frame 220, and the hinge module 300 to slide relative to the bending region Q3.

[0082] In some embodiments, the bending region Q3 is fixed to the first sliding frame 210 , the second sliding frame 220 and / or the hinge module 300 by electromagnetic adsorption.

[0083] In the folding display panel of this embodiment, the bending area Q3 is adsorbed and fixed to the first sliding frame 210, the second sliding frame 220 and / or the hinge module 300 by electromagnetic adsorption. Electromagnetic adsorption fixation is a controllable adsorption fixation method. When the first sliding frame 210, the second sliding frame 220 and the hinge module 300 need to slide, the electromagnetic force can be eliminated to facilitate the sliding of the first sliding frame 210, the second sliding frame 220 and the hinge module 300; when the first sliding frame 210, the second sliding frame 220 and the hinge module 300 do not need to slide, the electromagnetic force is generated to adsorb and fix the bending area Q3 to the first sliding frame 210, the second sliding frame 220 and the hinge module 300, thereby achieving a supporting and fixing effect on the bending area Q3.
