Description

Technical Field

[0001] The present invention relates to an electronic device, and more particularly to a display. Background Art

[0002] Flexible displays need to have a certain thickness due to impact resistance considerations or additional functional layers (such as touch layers or front light layers), and the rigidity of the display is highly correlated with the thickness and material properties of the display. Displays with high rigidity require greater force to roll up and are prone to warping and difficult to flatten, reducing the user experience. Existing technologies use mechanical components to flatten the display, but the display is prone to regional functional abnormalities under long-term stress, and the springs providing the pulling force are prone to fatigue and permanent deformation. Summary of the Invention

[0003] The present invention provides a display, which helps to reduce the pulling force required to flatten the display.

[0004] According to an embodiment of the present invention, the display includes a display size adjustment module and a flexible display module. The display size adjustment module includes a first element and a second element. The first element includes a plurality of first ribs arranged at intervals. The second element includes a plurality of second ribs arranged at intervals and slidably engaged with the plurality of first ribs. The size of the display increases as the second element slides away from the first element and decreases as the second element slides towards the first element. The flexible display module is disposed on the display size adjustment module and is bent to the back side of the display size adjustment module. The flexible display module includes a flexible display panel and a flexible support member for supporting the flexible display panel. The flexible support member is connected to the second element by at least one of magnetic adsorption, electrostatic adsorption, or snap members.

[0013] In an embodiment according to the present invention, at least one of the plurality of first ribs and an adjacent second rib have an interlocking buckle design.

[0014] In an embodiment according to the present invention, the flexible display module further includes a plurality of buckle members. The plurality of buckle members are arranged on the surface of the flexible support member facing the display size adjustment module. During the process of the second element sliding away from the first element, the plurality of second ribs slide away from the plurality of first ribs and engage with the plurality of buckle members.

[0015] In an embodiment according to the present invention, each side wall of the plurality of buckle members has a groove, and the groove engages with the upper edge of an adjacent second rib.

[0016] In an embodiment according to the present invention, the thickness of the plurality of buckle members is less than the thickness of the plurality of first ribs.

[0017] In an embodiment according to the present invention, the flexible support member includes a rigid portion and a sliding portion connecting the rigid portions.

[0093] Figure 1 And Figure 2 are respectively the three-dimensional schematic diagrams of a display in a storage state and an unfolded state according to the first embodiment of the present disclosure. Figure 3 is Figure 1 the partial cross-sectional schematic diagram of the display. Figure 4 is Figure 3 the partial cross-sectional schematic diagram of the flexible display module. Figure 5 And Figure 6They are respectively partial top-down schematic views of a display in a storage state and an unfolded state according to a first embodiment of the present disclosure.

[0094] A display 1 according to a first embodiment of the present disclosure is, for example, a slidable display, which may include a display size adjustment module 10 and a flexible display module 12 disposed on the display size adjustment module 10. In Figure 1 、 Figure 2 、 Figure 5 and Figure 6 for the sake of clearly showing the relative arrangement relationship of a plurality of components in the display size adjustment module 10 located below the flexible display module 12, the flexible display module 12 is omitted from being shown.

[0095] Please first refer to Figure 1 and Figure 2 , the display size adjustment module 10 is used to adjust the size of the display 1. For example, the width W of the display 1 in the first direction D1 can be enlarged or reduced by the display size adjustment module 10, but not limited thereto.

[0096] Specifically, the display size adjustment module 10 may include a first element 100 and a second element 102. The first element 100 may include a plurality of first ribs R1 arranged at intervals. The plurality of first ribs R1 extend, for example, in the first direction D1 and are arranged in the second direction D2. The first direction D1 and the second direction D2 are both perpendicular to the thickness direction of the display 1 (such as the third direction D3). In addition, the first direction D1 and the second direction D2 intersect with each other and are, for example, perpendicular to each other, but not limited thereto. In some embodiments, as shown in the figure, the first element 100 may further include a first connecting member C1. The first connecting member C1 extends, for example, in the second direction D2 and is connected to a plurality of ends of the plurality of first ribs R1 away from the second element 102.

[0097] The second element 102 may include a plurality of second ribs R2 arranged at intervals and slidably engaged with the plurality of first ribs R1. The plurality of second ribs R2 extend, for example, in the first direction D1 and are arranged in the second direction D2. In addition, the plurality of first ribs R1 and the plurality of second ribs R2 are, for example, alternately arranged in the second direction D2. In some embodiments, as shown in the figure, the second element 102 may further include a second connecting member C2. The second connecting member C2 extends, for example, in the second direction D2 and is connected to a plurality of ends of the plurality of second ribs R2 away from the first element 100. In other words, the first connecting member C1 and the second connecting member C2 are respectively located on opposite sides of the plurality of first ribs R1 and the plurality of second ribs R2.

[0098] In some embodiments, the first element 100 is, for example, a fixed part, while the second element 102 is, for example, a movable part. By moving the second element 102 relative to the first element 100 (for example, changing the distance between the first connecting member C1 and the second connecting member C2), the size of the display 1 can be adjusted (for example, enlarging or reducing the width W of the display 1 in the first direction D1). Specifically, as Figure 2 shown, the size of the display 1 can increase as the second element 102 slides away from the first element 100, and as Figure 1 shown, the size of the display 1 can decrease as the second element 102 slides towards the first element 100.

[0099] Figure 1 Schematically shows the storage state (non-expanded state) of the display 1. In the storage state, a plurality of first ribs R1 can contact the second connecting member C2, and the first gap G1 between any two adjacent first ribs R1 is occupied by the corresponding second rib R2. In addition, a plurality of second ribs R2 can contact the first connecting member C1, and the second gap G2 between any two adjacent second ribs R2 is occupied by the corresponding first rib R1.

[0100] Figure 2 Schematically shows the expanded state of the display 1. In the expanded state, a plurality of first ribs R1 are separated from the second connecting member C2, and a part of the first gap G1 between any two adjacent first ribs R1 is not occupied by the corresponding second rib R2. In addition, a plurality of second ribs R2 are separated from the first connecting member C1, and a part of the second gap G2 between any two adjacent second ribs R2 is not occupied by the corresponding first rib R1.

[0101] Please refer to Figure 3 and Figure 4 , the flexible display module 12 is disposed on the display size adjustment module 10 and bent to the back side BS of the display size adjustment module 10 to achieve the storage purpose. The flexible display module 12 is used to display images. For example, the flexible display module 12 can be a self-luminous display module or a non-self-luminous display module. The self-luminous display module can include an organic light-emitting diode display module, but is not limited thereto. The non-self-luminous display module can include a reflective display module, such as an electrophoretic display module, but is not limited thereto.

[0102] The flexible display module 12 can include a flexible display panel 120 and a flexible support 122 for supporting the flexible display panel 120, but is not limited thereto. According to different requirements, the flexible display module 12 can also include other components or film layers. For example, as Figure 4 shown, the flexible display module 12 can also include a cover plate 124 and a functional layer 126, wherein the flexible display panel 120, the functional layer 126, and the cover plate 124 are, for example, sequentially disposed on the flexible support 122.

[0103] The material of the flexible support member 122 may include a metal to have a support function, flexibility, and / or heat dissipation function, but is not limited thereto. In some embodiments, the portion of the flexible support member 122 bent to the back side BS of the display size adjustment module 10 may include a plurality of openings (such as Figure 11 the plurality of openings A shown) to improve flexibility or bendability, but is not limited thereto. In other embodiments, a thinner flexible support member 122 and / or a back protective layer (not shown) may be used, so that the flexible support member 122 does not necessarily require a plurality of openings.

[0104] The flexible display panel 120 is located between the flexible support member 122 and the functional layer 126. Although not shown, the flexible display panel 120 may include a display medium, driving elements, a back protective layer, etc., but is not limited thereto. The display medium may include a micro-capsule electrophoresis array, a micro-cup electrophoresis array, an organic light-emitting diode array, etc., but is not limited thereto. The driving elements may include an active element array, a gate driver, and / or a source driver, etc., but is not limited thereto. The material of the back protective layer may include an insulating material, such as plastic, an organic insulating material, and / or an inorganic insulating material, etc., but is not limited thereto.

[0105] The functional layer 126 is located between the flexible display panel 120 and the cover plate 124. The functional layer 126 may include a touch layer and / or a front light layer, etc., but is not limited thereto. The cover plate 124 is disposed on the functional layer 126. The material of the cover plate 124 may include a flexible substrate material, such as plastic, but is not limited thereto.

[0106] According to different requirements, the display 1 may further include one or more elements or film layers. For example, as Figures 1 to 3 shown, the display 1 may further include a roller 14 to guide the bending of the flexible display module 12. The roller 14 is disposed on a side of the second element 102 away from the first element 100, and the flexible display module 12 is bent around the roller 14 to the back side BS of the display size adjustment module 10.

[0107] In some embodiments, the plurality of first ribs R1 and the plurality of second ribs R2 in the display size adjustment module 10 may contact the flexible support member 122 in the flexible display module 12 to support the flexible display module 12. In addition, according to different embodiments, the flexible support member 122 may be connected to the second element 102 in the display size adjustment module 10 by at least one of magnetic adsorption, electrostatic adsorption, or a snap member, so that the flexible display module 12 can be flatly attached to the second element 102.

[0108] Figure 5 and Figure 6Schematically show an embodiment in which the flexible support is magnetically adsorbed and connected to the second element 102. Please refer to Figure 5 and Figure 6 , the side walls of the plurality of second ribs R2 (such as the side wall SW2 parallel to the reference plane formed by the first direction D1 and the third direction D3) may include a plurality of second grooves GV2, and the second element 102 further includes a plurality of second ejection mechanisms PU2 embedded in the plurality of second grooves GV2.

[0109] In some embodiments, the second element 102 may further include a plurality of second rotating shafts RA2. The plurality of second ejection mechanisms PU2 are respectively arranged corresponding to the plurality of second rotating shafts RA2 and can be fixed in the plurality of second grooves GV2 through the plurality of second rotating shafts RA2. In addition, the second ejection mechanism PU2 can rotate around the second rotating shaft RA2 as the axis.

[0110] During the process of the second element 102 sliding away from the first element 100, as Figure 6 shown, the plurality of second grooves GV2 are exposed by the plurality of first ribs R1 (that is, the plurality of second grooves GV2 are no longer blocked by the plurality of first ribs R1), so that the plurality of second ejection mechanisms PU2 can eject from the plurality of second grooves GV2. On the other hand, during the process of the second element 102 sliding towards the first element 100, as Figure 5 shown, the plurality of second ejection mechanisms PU2 are squeezed by the plurality of first ribs R1 and return to the plurality of second grooves GV2. In some embodiments, when viewed from a top view, the ends of the plurality of first ribs R1 facing the second element 102 may be pointed, so as to facilitate pushing the ejected second ejection mechanism PU2 back into the second groove GV2.

[0111] In some embodiments, the plurality of second ejection mechanisms PU2 may have magnetism, and the material of the flexible support 122 (refer to Figure 4 ) may include paramagnetic materials or ferromagnetic materials. In this way, an attractive force can be generated between the plurality of second ejection mechanisms PU2 and the flexible support 122, so that the flexible display module 12 can also be flatly attached to the display size adjustment module 10 when the display 1 is in the unfolded state, and it is not necessary to use a very large pulling force to flatten the panel, which helps to extend the service life of the display 1 and / or reduce the difficulty of mechanism design. Paramagnetic materials may include aluminum, oxygen, titanium, and iron oxide (FeO), but are not limited thereto. Ferromagnetic materials may include materials such as iron, cobalt, nickel and their compounds and alloys, but are not limited thereto.

[0112] In some embodiments, adjacent two second ejection mechanisms PU2 corresponding to the same second rib R2 (for example, adjacent two second ejection mechanisms PU2 located at opposite sidewalls SW2 of the same second rib R2) can be arranged in a manner of magnetic like poles (for example, N pole against N pole, or S pole against S pole, where “N” represents the N pole and “S” represents the S pole in the figure), so that adjacent two second ejection mechanisms PU2 corresponding to the same second rib R2 repel each other, thereby when multiple second grooves GV2 are exposed by multiple first ribs R1 (as Figure 6 shown), adjacent two second ejection mechanisms PU2 corresponding to the same second rib R2 can automatically eject two second grooves GV2.

[0113] On the other hand, adjacent two second ejection mechanisms PU2 corresponding to adjacent two second ribs R2 can be arranged in a manner of magnetic unlike poles (for example, N pole against S pole), so that adjacent two second ejection mechanisms PU2 corresponding to adjacent two second ribs R2 attract each other after ejecting two second grooves GV2, which helps to improve the stability of multiple second ribs R2 located outside multiple second grooves GV2.

[0114] When the display 1 is in the unfolded state, multiple second ejection mechanisms PU2 ejected from multiple second grooves GV2 not only help to flatten the flexible display module 12, but also can fill the second gap G2 between multiple second ribs R2. In this way, when the user performs a touch operation (for example, when pressing the flexible display module 12 with a finger or a stylus), it is less likely to notice the void (second gap G2) located below the flexible display module 12.

[0115] In some embodiments, multiple sidewalls SW1 of multiple first ribs R1 can include multiple first grooves GV1, and the first element 100 can further include multiple first ejection mechanisms PU1 embedded in multiple first grooves GV1.

[0116] In some embodiments, the first element 100 further includes multiple first rotating shafts RA1. Multiple first ejection mechanisms PU1 are respectively arranged corresponding to multiple first rotating shafts RA1 and can be fixed in multiple first grooves GV1 through multiple first rotating shafts RA1. In addition, the first ejection mechanism PU1 can rotate around the first rotating shaft RA1 as the axis.

[0117] During the process of the second element 102 sliding away from the first element 100, as Figure 6 shown, multiple first grooves GV1 are exposed by multiple second ribs R2 (that is, multiple first grooves GV1 are no longer blocked by multiple second ribs R2), so that multiple first ejection mechanisms PU1 can eject multiple first grooves GV1. On the other hand, during the process of the second element 102 sliding towards the first element 100, as Figure 5As shown, multiple first ejection mechanisms PU1 are pushed back into multiple first grooves GV1 under the extrusion of multiple second ribs R2. In some embodiments, when viewed from a top view, the multiple second ribs R2 may be pointed towards the multiple ends of the first element 100, so as to easily push the ejected first ejection mechanisms PU1 back into the first grooves GV1.

[0118] The multiple first ejection mechanisms PU1 may or may not have magnetism. When the multiple first ejection mechanisms PU1 have magnetism, the magnetic design can refer to the relevant description of the multiple second ejection mechanisms PU2, which will not be elaborated here.

[0119] When the display 1 is in the unfolded state, the multiple first ejection mechanisms PU1 that pop out of the multiple first grooves GV1 can fill the first gap G1 between the multiple first ribs R1. In this way, when the user performs a touch operation, it is less likely to notice the void (first gap G1) located below the flexible display module 12.

[0120] Figure 7 And Figure 8 are respectively partial top view schematic diagrams of a display in a retracted state and an unfolded state according to a second embodiment of the present disclosure. Figure 9 And Figure 10 are respectively Figure 8 The cross-sectional schematic diagrams corresponding to the section lines I-I' and II-II' in. In Figure 7 And Figure 8 , in order to clearly show the relative setting relationship of multiple elements in the display size adjustment module located below the flexible display module, the flexible display module is omitted.

[0121] Please refer to Figure 7 And Figure 8 , the main differences between the display 1A and Figure 5 And Figure 6 The display 1 are described as follows. In the display 1A, the top view shapes of the multiple first ejection mechanisms PU1 and the multiple second ejection mechanisms PU2 are different from those Figure 5 And Figure 6 Shown in. In addition, in the display 1A, the second element 102A does not include Figure 5 And Figure 6 The multiple second rotating shafts RA2 in, and the second element 102A further includes multiple second springs SP2. The multiple second ejection mechanisms PU2 are respectively arranged corresponding to the multiple second springs SP2 and can eject the multiple second grooves GV2 through the multiple second springs SP2. Additionally, in the display 1A, the first element 100A does not include Figure 5 And Figure 6a plurality of first rotating shafts RA1 therein, and the first element 100A further includes a plurality of first springs SP1. A plurality of first ejecting mechanisms PU1 are respectively arranged corresponding to the plurality of first springs SP1 and can eject a plurality of first grooves GV1 through the plurality of first springs SP1.

[0122] In some embodiments, two adjacent first ejecting mechanisms PU1 corresponding to two adjacent first ribs R1 may have an interlocking buckle design. As Figure 9 shown, two adjacent first ejecting mechanisms PU1 may respectively include a female buckle and a male buckle with complementary shapes, but are not limited thereto.

[0123] In some embodiments, at least one of the plurality of first ribs R1 and an adjacent second rib R2 may also have an interlocking buckle design. As Figure 10 shown, the adjacent first rib R1 and the second rib R2 may respectively include a female buckle and a male buckle with complementary shapes, but are not limited thereto.

[0124] It should be understood that Figure 9 and Figure 10 the interlocking buckle design shown is only an example and is not used to limit the present disclosure. The interlocking buckle design described herein should cover any known design applicable to the architecture of the present disclosure.

[0125] In addition, although Figures 5 to 8 schematically shows an implementation manner in which the flexible support is magnetically adsorbed and connected to the second element, the present disclosure is not limited thereto. In other embodiments, although not shown, the flexible support can be connected to the display size adjustment module by electrostatic adsorption instead of magnetic adsorption. For example, the materials of the flexible support and the second element may include conductive materials. By making the flexible support and the second element have different electricities, the flexible display module can be flatly attached to the display size adjustment module when the display is in the unfolded state, and it is not necessary to use a very large pulling force to flatten the panel, thereby helping to extend the service life of the display and / or reduce the difficulty of mechanism design.

[0126] Figure 11 is a partial top view schematic diagram of a flexible support of a display according to a third embodiment of the present disclosure. Figure 12 and Figure 13 are respectively partial cross-sectional schematic diagrams of a display according to a third embodiment of the present disclosure in the stored state and the unfolded state. For the sake of simplicity of the drawings, Figure 12 and Figure 13 omit showing the film layers (such as Figure 4 the cover plate 124 and the functional layer 126 in

[0127] Please refer to Figures 11 to 13, the main differences between the display 1B and the aforementioned displays (such as display 1 or display 1A) are described as follows. In the display 1B, the flexible support member 122 is connected to the second element 102B by a snap member 128, rather than being connected to the second element 102B by magnetic adsorption or electrostatic adsorption. In this architecture, the material of the flexible support member 122 may not include paramagnetic materials or ferromagnetic materials. In addition, the first element 100B may adopt a design similar to that of the first element 100 in Figure 5 and Figure 6 , or adopt a design similar to that of the first element 100A in Figure 7 and Figure 8 . Alternatively, the first element 100B may omit Figure 5 and Figure 6 such as multiple first grooves GV1, multiple first ejection mechanisms PU1, and multiple first rotating shafts RA1, or omit Figure 7 and Figure 8 such as multiple first grooves GV1, multiple first ejection mechanisms PU1, and multiple first springs SP1. Similarly, the second element 102B may adopt a design similar to that of the second element 102 in Figure 5 and Figure 6 , or adopt a design similar to that of the second element 102A in Figure 7 and Figure 8 . Alternatively, the second element 102B may omit Figure 5 and Figure 6 such as multiple second grooves GV2, multiple second ejection mechanisms PU2, and multiple second rotating shafts RA2, or omit Figure 7 and Figure 8 such as multiple second grooves GV2, multiple second ejection mechanisms PU2, and multiple second springs SP2.

[0128] In addition, the flexible display module 12B may further include a plurality of snap members 128. The plurality of snap members 128 are disposed on the surface of the flexible support member 122 facing the display size adjustment module 10B. During the process of the second element 102B sliding away from the first element 100B, as shown in Figure 13 , the plurality of second ribs R2 slide away from the plurality of first ribs R1 and engage with the plurality of snap members 128. In some embodiments, each of the first ribs R1 and an adjacent second rib R2 may have an interlocking snap design, and two adjacent second ribs R2 and the snap member 128 located therebetween may have an interlocking snap design. As shown in Figure 13 , the side wall SW128 of each of the plurality of snap members 128 may have a groove T, and the groove T engages with the upper edge of an adjacent second rib 128. In some embodiments, as shown in Figure 12 and Figure 13As shown, the thickness T128 of the plurality of fastening members 128 may be less than the thickness TR1 of the plurality of first ribs R1.

[0129] The material of the plurality of fastening members 128 may include, but is not limited to, metal, plastic, or rubber. In some embodiments, the plurality of fastening members 128 may be made together with the flexible support member 122, and the plurality of fastening members 128 and the flexible support member 122 may have the same material, but is not limited thereto. In other embodiments, the plurality of fastening members 128 and the flexible support member 122 may have different materials, and the plurality of fastening members 128 may be formed on the surface of the flexible support member 122 facing the display size adjustment module 10B by means of adhesion, welding, or 3D printing, etc.

[0130] In some embodiments, the flexible support member 122 may include a rigid portion 122a and a sliding portion 122b connecting the rigid portion 122a, and the sliding portion 122b includes a plurality of openings A. When the display is in the unfolded state (refer to Figure 2 ), the sliding portion 122b overlaps the second element (including the second connecting member C2 and the plurality of second ribs R2), and the rigid portion 122a overlaps the portion of the first element that does not intersect with the second element (including the first connecting member C1 and the portion of the plurality of first ribs R1 that does not intersect with the plurality of second ribs R2). By forming a plurality of openings A in the portion of the flexible support member 122 that is bent to the back side of the display size adjustment module 10B, the flexibility or bendability of the flexible support member 122 can be improved.

[0131] In some embodiments, as Figure 11 shown, the plurality of openings A may be staggered in the first direction D1 and aligned in the second direction D2 to form a plurality of H-shaped connection portions (see the dashed box in Figure 11 ). In this architecture, the plurality of fastening members 128 may be disposed adjacent to the plurality of corners C of the plurality of H-shaped connection portions to reduce the probability of deformation of the flexible support member 122.

[0132] Figure 14 is a partial bottom-up schematic view of a flexible support member of a display according to a fourth embodiment of the present disclosure. Figure 15 is a partial cross-sectional schematic view of a display according to a fourth embodiment of the present disclosure. Figure 16 is a three-dimensional schematic view of a roller of a display according to a fourth embodiment of the present disclosure. For the sake of simplicity of the drawings, Figure 15 the film layers (such as the flexible display panel 120, the cover plate 124, and the functional layer 126 in Figure 4 ) located on the flexible support member 122 are omitted from showing.

[0133] Please refer to Figures 14 to 16 , the display 1C and Figures 11 to 13The main differences of the display 1B are described as follows. In the display 1C, a plurality of snap members 128C are strip-shaped snap members extending along the first direction D1, and the plurality of snap members 128C are formed, for example, by welding or pasting on the surface of the flexible support 122 facing the display size adjustment module 10B.

[0134] Forming the plurality of snap members 128C by pasting is conducive to mass production. In addition, when the flexible display module 12C is bent on the roller 14C, the glue between the plurality of snap members 128C and the flexible display module 12C can provide buffering, reducing the interference or wear between the plurality of snap members 128C and the flexible display module 12C.

[0135] In some embodiments, the surface of each of the plurality of snap members 128C facing the display size adjustment module 10B may have a repetitive inverted trapezoidal structure ITS, making the plurality of snap members 128C easy to bend at the roller 14C. In addition, the roller 14C may have a plurality of annular grooves AG corresponding to the plurality of snap members 128C, so that the flexible display module 12C will not locally protrude due to the arrangement of the plurality of snap members 128C on the roller 14.

[0136] Figure 17 is a partial cross-sectional schematic view of a display according to the fifth embodiment of the present disclosure. Figure 18 and Figure 19 are respectively a partial top-down schematic view and a partial cross-sectional schematic view of a display in an unfolded state according to the fifth embodiment of the present disclosure. For the sake of simplicity of the drawings, Figure 17 the film layers located on the flexible support 122 (such as Figure 4 the flexible display panel 120, the cover plate 124, and the functional layer 126 in Figure 18 ) are omitted from being shown. In addition, Figure 19 the flexible display module is omitted to clearly show the relative arrangement relationship of the plurality of elements in the display size adjustment module located below the flexible display module. Additionally,

[0137] Please refer to Figures 17 to 19 , the display 1D, Figures 14 to 16 the display 1C of Figure 7 and Figure 8The main differences of the display 1A are described as follows. In the display 1D, a plurality of snap members provided on the surface of the flexible support member 122 facing the display size adjustment module 10B are a plurality of hanging snap members 128D. During the process of the second element 102A sliding away from the first element 100A, a plurality of second grooves GV2 are exposed by a plurality of first ribs R1, and a plurality of second ejection mechanisms PU2 eject the plurality of second grooves GV2 and form a snap state with the plurality of hanging snap members 128D. As Figure 18 and Figure 19 shown, the hanging snap members 128D can pass through two adjacent ejected second ejection mechanisms PU2 and abut under the two ejected second ejection mechanisms PU2, flattening the flexible display module 12D, so that a very large pulling force does not need to be used to flatten the panel. On the other hand, during the process of the second element 102A sliding towards the first element 100A, the plurality of second ejection mechanisms PU2 are squeezed by the plurality of first ribs R1 and return into the plurality of second grooves GV2 (refer to Figure 7 ). In addition, as the flexible display module 12D is bent to the back side BS of the display size adjustment module 10B, the plurality of hanging snap members 128D are flat against the surface of the flexible support member 122 facing the display size adjustment module 10B, as Figure 17 shown.

[0138] It should be understood that Figure 18 and Figure 19 the shape of the second ejection mechanism PU2 in Figure 17 is only schematic and can be changed according to actual needs. In addition, Figure 16 the roller 14 in can be replaced with Figure 16 the roller 14C in or other types of rollers, which are not limited herein.

[0139] Figure 20 is a partial cross-sectional schematic view of a display according to a sixth embodiment of the present disclosure. Figure 21 is a partial top-down schematic view of a display in an unfolded state according to a sixth embodiment of the present disclosure. Figure 22 is Figure 21 a three-dimensional schematic view of the hook-shaped snap member in Figure 21 . Figure 23 is corresponding to Figure 21 a cross-sectional schematic view of the section line III-III'. For the sake of simplicity of the drawings, Figure 20 the film layers (such as Figure 4 the cover plate 124 and the functional layer 126 in Figure 4 ) located on the flexible display panel 120 are omitted. In addition, Figure 21 the flexible display module is omitted to clearly show the relative setting relationship of the plurality of elements in the display size adjustment module located below the flexible display module.

[0140] Please refer to Figure 21 andFigure 21 , the main differences between the display 1E and Figures 17 to 19 the display 1D are described as follows. In the display 1E, a plurality of snap members provided on the surface of the flexible support member 122 facing the display size adjustment module 10B are a plurality of annular snap members L, and the plurality of annular snap members L are adjacent to the end of the flexible support member 122 away from the first element 100B. In addition, the second element 102E further includes a plurality of hook-shaped snap members H. The plurality of hook-shaped snap members H are embedded in the plurality of second ribs R2 and adjacent to the plurality of ends of the plurality of second ribs R2 away from the first element 100B. During the process of the second element 102E sliding away from the first element 100B, the plurality of hook-shaped snap members H and the plurality of annular snap members L form a snap state. By forming a snap state between the plurality of hook-shaped snap members H and the plurality of annular snap members L, a force can be provided in the third direction D3 to resist the separation of the flexible support member 122 and the display size adjustment module 10B, flattening the flexible display module 12E, and thus it is not necessary to use a great pulling force to flatten the panel. For example, the annular snap member L can be the annular snap end in a Hook-and-loop fastener, and the hook-shaped snap member H can be the hook-shaped snap end in the Hook-and-loop fastener.

[0141] In some embodiments, as Figure 22 and Figure 23 shown, each of the plurality of hook-shaped snap members H may have a roller R and a plurality of hooks HK located on the roller R. During the process of the second element 102E sliding away from the first element 100B (refer to Figure 21 ), the roller R rotates counterclockwise, for example, and during the process of the second element 102E sliding towards the first element 100B, the roller R rotates clockwise, for example.

[0142] Through the roller design of the hook-shaped snap member H, it helps to separate the plurality of hook-shaped snap members H and the plurality of annular snap members L from each other during the relative movement of the second element 102E with respect to the first element 100B.

[0143] In summary, in the embodiments of the present invention, the flexible support member can be connected to the second element by at least one of magnetic adsorption, electrostatic adsorption or snap members, so that the flexible display module can also be flatly attached to the display size adjustment module when the display is in the unfolded state, and it is not necessary to use a great pulling force to flatten the panel, thereby helping to extend the service life of the display and / or reduce the difficulty of mechanism design.

[0144] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
