[0002] Electronic devices are often equipped with display devices to display various information.

[0003] In related technologies, there exists a display device that includes a flexible display panel. Due to the characteristics of the flexible display panel, it can be unfolded when in use and rolled up when not in use.

[0004] However, due to the characteristics of flexible display panels, their structural strength is relatively poor, and they are easily damaged by external forces. Summary of the Invention

[0005] To overcome the problems existing in related technologies to a certain extent, this disclosure provides a pressing component, a display device, and an electronic device, the technical solutions of which are as follows:

[0006] According to one aspect of this disclosure, a pressing assembly is provided, including a support member and a plurality of pressing members;

[0007] Multiple edge-pressing members are arranged sequentially along the outer edge of the support member to fix the flexible display panel that is in contact with one side of the support member;

[0008] When the edge pressing assembly is in the winding state, the multiple edge pressing members can be wound together with the flexible display panel.

[0009] In one implementation of this disclosure, the pressing member includes a first mounting part, a connecting part, and a second mounting part connected in sequence;

[0010] The first mounting portion and the second mounting portion are opposite to each other, so that an accommodating space is formed between the first mounting portion, the connecting portion and the second mounting portion;

[0011] One side of the flexible display panel is located within the accommodating space and is connected to the first mounting part;

[0012] One side of the support member is located within the accommodating space and is slidably connected to the second mounting part.

[0013] In one implementation of this disclosure, when the pressing assembly is in the unfolded state, the distance between the second mounting portions of two adjacent pressing members is greater than the distance between the first mounting portions of two adjacent pressing members.

[0014] In one implementation of this disclosure, the longitudinal section of the connecting portion is trapezoidal in the direction from the first mounting portion to the second mounting portion;

[0015] The side of the connecting part that is connected to the first mounting part is the lower base of the trapezoid, and the side of the connecting part that is connected to the second mounting part is the upper base of the trapezoid.

[0016] The orthographic projections of the first mounting portion and the second mounting portion onto the plane where the connecting portion is located are both located within the connecting portion.

[0017] In one implementation of this disclosure, the trapezoid is an isosceles trapezoid.

[0018] In one implementation of this disclosure, the first mounting portion includes a first substrate and an adhesive layer;

[0019] The first substrate is connected to the connecting portion;

[0020] The adhesive layer is located on the side of the first substrate facing the second mounting portion.

[0021] In one implementation of this disclosure, the second mounting portion includes a second substrate and a protrusion;

[0022] The second substrate is connected to the connecting portion;

[0023] The protrusion is connected to the second substrate, and the protrusion is away from the connecting portion;

[0024] The support member has a groove on the side facing the second mounting portion, the groove extending along the arrangement direction of the plurality of pressing members, and the protrusion being movably inserted into the groove.

[0025] In one implementation of this disclosure, the end of the protrusion facing away from the second substrate is arc-shaped, and the end of the protrusion facing away from the second substrate slides in contact with the bottom of the groove.

[0026] According to another aspect of this disclosure, a display device is provided, including a flexible display panel and the aforementioned edge-pressing assembly;

[0027] The flexible display panel is attached to the support member, and an outer edge of the flexible display panel and an outer edge of the support member are simultaneously inserted into the pressing member.

[0028] In one implementation of this disclosure, one outer edge of the flexible display panel and one outer edge of the support member are simultaneously inserted into a portion of the pressing member, and another opposite outer edge of the flexible display panel and another opposite outer edge of the support member are simultaneously inserted into another portion of the pressing member.

[0029] According to another aspect of this disclosure, an electronic device is provided, including the display device described above.

[0030] The beneficial effects of the technical solutions provided in this disclosure include at least the following:

[0031] After the edge-pressing component provided in this embodiment is configured in the display device, when the flexible display panel is unfolded, the edge-pressing component is in the unfolded state, and one side of the support member is in contact with the flexible display panel. This provides stable support for the flexible display panel, effectively strengthening its structural strength and preventing damage under external forces. Furthermore, the edge-pressing component secures the flexible display panel and the support member together, preventing the flexible display panel from detaching from the support member and further ensuring the support member's support for the flexible display panel. Additionally, when the flexible display panel is rolled up, the edge-pressing component is in the rolled-up state. The support member no longer supports the flexible display panel, while the edge-pressing component rolls up along with the flexible display panel. Therefore, the edge-pressing component does not affect the normal rolling up of the flexible display panel.

[0032] In other words, the edge-pressing component provided in this embodiment can provide stable support for the flexible display panel when it is in the unfolded state, and can also be rolled up together with the flexible display panel when it is in the rolled-up state.

[0051] Electronic devices are often equipped with display devices to display various information.

[0052] In related technologies, there exists a display device that includes a flexible display panel. Due to the characteristics of the flexible display panel, it can be unfolded when in use and rolled up when not in use.

[0053] However, due to the characteristics of flexible display panels, their structural strength is relatively poor, and they are easily damaged by external forces.

[0054] To address the aforementioned technical problems, this disclosure provides a pressing assembly. Figure 1 See the schematic diagram of the pressing edge assembly. Figure 1 In this embodiment, the pressing component includes a support member 10 and a plurality of pressing members 20.

[0055] Multiple edge-pressing members 20 are arranged sequentially along the outer edge of the support member 10 to fix the flexible display panel 100 that is in contact with one side of the support member 10. When the edge-pressing assembly is in the winding state, the multiple edge-pressing members 20 can be wound together with the flexible display panel 100.

[0056] After the edge-pressing component provided in this embodiment is disposed on the display device, the edge-pressing component is in the unfolded state when the flexible display panel 100 is unfolded (see [link]). Figure 2 One side of the support member 10 is in contact with the flexible display panel 100, thereby providing stable support for the flexible display panel 100 and effectively strengthening its structural strength, preventing damage under external forces. Furthermore, the edge clamping member 20 secures the flexible display panel 100 and the support member 10 together, preventing the flexible display panel 100 from detaching from the support member 10 and further ensuring the support member 10's support for the flexible display panel 100. Additionally, when the flexible display panel 100 is rolled up, the edge clamping member is in the rolling state (see...). Figure 3 In this configuration, the support member 10 no longer supports the flexible display screen, while the edge pressing member 20 can be rolled up together with the flexible display panel 100. In this way, the edge pressing member will not affect the normal rolling up of the flexible display panel 100.

[0057] In other words, the edge-pressing component provided in this embodiment can provide stable support for the flexible display panel 100 when it is in the unfolded state, and can also be rolled up together with the flexible display panel 100 when it is in the rolled-up state.

[0058] As mentioned above, the edge clamping component 20 plays a crucial role in fixing the flexible display screen on the support component 10. The edge clamping component 20 will be introduced below.

[0059] Figure 4 This is a structural schematic diagram of the blank holder 20, combined with... Figure 4 In this embodiment, the pressing member 20 includes a first mounting part 210, a connecting part 220 and a second mounting part 230 connected in sequence. The first mounting part 210 and the second mounting part 230 are opposite to each other so that an accommodating space 240 is formed between the first mounting part 210, the connecting part 220 and the second mounting part 230.

[0060] In the above implementation, the first mounting part 210 is used to mount the flexible display panel 100, the second mounting part 230 is used to mount the support member 10, and the connecting part 220 is used to connect the first mounting part 210 and the second mounting part 230 together, so that the flexible display panel 100 inserted in the accommodating space 240 and the support member 10 can be in contact, thereby supporting the flexible display panel 100 through the support member 10.

[0061] Figure 5 This is an assembly diagram of the blank holder 20, combined with... Figure 4 and Figure 5 In this embodiment, one side of the flexible display panel 100 is located within the accommodating space 240 and is connected to the first mounting portion 210. One side of the support member 10 is located within the accommodating space 240 and is slidably connected to the second mounting portion 230.

[0062] The flexible display panel 100 is connected to the first mounting portion 210, meaning the flexible display panel 100 remains relatively stationary with respect to the edge clamping member 20. The support member 10 is slidably connected to the second mounting portion 230, meaning the support member 10 can move relative to the edge clamping member 20. Thus, when the flexible display panel 100 switches between an unfolded state and a rolled-up state, the edge clamping member 20 moves along with the flexible display panel 100. When the flexible display panel 100 switches from a rolled-up state to an unfolded state, the flexible display panel 100 moves relative to the support member 10, and the edge clamping member 20 moves synchronously relative to the support member 10 until the flexible display panel 100 gradually lies flat on the support member 10, thus completing the unfolding. When the flexible display panel 100 switches from an unfolded state to a rolled-up state, the flexible display panel 100 moves relative to the support member 10, and the edge clamping member 20 moves synchronously relative to the support member 10 until the flexible display panel 100 gradually detaches from the support member 10, thus completing the rolling-up.

[0063] It is easy to understand that the flexible display panel 100 can be rolled up because of its flexible properties. The reason why the multiple edge-pressing members 20 can be rolled up together with the flexible display panel 100 is that there is a certain amount of space between two adjacent edge-pressing members 20, which can produce corresponding overall deformation as the flexible display panel 100 is rolled up (the edge-pressing members 20 themselves do not deform, but the overall shape formed by the combination of multiple edge-pressing members 20 deforms).

[0064] See you again Figure 2 In this embodiment, when the pressing assembly is in the unfolded state, the distance between the second mounting portions 230 of two adjacent pressing members 20 is greater than the distance between the first mounting portions 210 of two adjacent pressing members 20.

[0065] In the above implementation, since the distance between two adjacent second mounting portions 230 is greater than the distance between two adjacent first mounting portions 210, a movable space is formed between the two adjacent second mounting portions 230, allowing the multiple edge-pressing members 20 to deform as a whole. For example, when the edge-pressing assembly is in the unfolded state, the distance between two adjacent second mounting portions 230 is greater than the distance between two adjacent first mounting portions 210. When the edge-pressing assembly is in the rolled-up state, the distance between two adjacent second mounting portions 230 is significantly reduced, while the distance between two adjacent first mounting portions 210 remains unchanged or changes slightly. After the multiple edge-pressing members 20 are rolled up, within the same edge-pressing member 20, the second mounting portion 230 is closer to the center of the flexible display screen than the first mounting portion 210.

[0066] Figure 6 for Figure 2 A sectional view along the AA direction, combined with Figure 6 In this embodiment, the longitudinal section of the connecting portion 220 is trapezoidal in the direction from the first mounting portion 210 to the second mounting portion 230.

[0067] The side of the connecting part 220 that is connected to the first mounting part 210 is the lower base of a trapezoid, and the side of the connecting part 220 that is connected to the second mounting part 230 is the upper base of a trapezoid. The orthographic projections of the first mounting part 210 and the second mounting part 230 on the plane where the connecting part 220 is located are both within the connecting part 220.

[0068] In the above implementation, because the upper base of the trapezoid is shorter than the lower base, the distance between two adjacent second mounting portions 230 is greater than the distance between two adjacent first mounting portions 210. When the edge-pressing assembly is in the rolled-up state, the waists of two adjacent trapezoids are in contact.

[0069] For example, the trapezoid is an isosceles trapezoid. This design allows for sufficient movement between the two edge clamping members 20, ensuring a large overall deformation range of the multiple edge clamping members 20 to accommodate the winding of the flexible display panel 100.

[0070] The previous section introduced the winding method of the edge clamping member 20. The following section will introduce the installation method between the edge clamping member 20, the flexible display panel 100, and the support member 10.

[0071] Figure 7 for Figure 2 BB direction sectional view, combined Figure 7 In this embodiment, the first mounting portion 210 includes a first substrate 211 and an adhesive layer 212. The first substrate 211 is connected to the connecting portion 220, and the adhesive layer 212 is located on the side of the first substrate 211 facing the second mounting portion 230.

[0072] In the above implementation, the first substrate 211 serves as the main body of the first mounting portion 210, providing a stable connection base for the flexible display panel 100. The adhesive layer 212 is used to bond the flexible display panel 100 to the first substrate 211, thereby realizing the connection between the first mounting portion 210 and the flexible display panel 100.

[0073] Furthermore, since the first substrate 211 is a plate-shaped structure, it can better adhere to the flexible display panel 100, thereby ensuring the contact area between the first mounting part 210 and the flexible display panel 100, and thus improving the connection firmness between the first mounting part 210 and the flexible display panel 100.

[0074] For example, the first substrate 211 is a rectangular plate. In other embodiments, the first substrate 211 may also be a plate of other shapes, such as triangles, rhombuses, etc. This disclosure does not limit it.

[0075] For example, the adhesive layer 212 is an adhesive applied to the first substrate 211, or a double-sided adhesive applied to the first substrate 211. This disclosure does not limit this.

[0076] See also Figure 7 In this embodiment, the second mounting portion 230 includes a second substrate 231 and a protrusion 232. The second substrate 231 is connected to the connecting portion 220, the protrusion 232 is connected to the second substrate 231, and the protrusion 232 is away from the connecting portion 220.

[0077] The support member 10 has a groove 110 on the side facing the second mounting part 230. The groove 110 extends along the arrangement direction of the plurality of pressing members 20, and the protrusion 232 is movably inserted into the groove 110.

[0078] In the above implementation, the second substrate 231 is the main body of the second mounting portion 230, which is used to provide a stable support base for the support member 10. The protrusion 232 is inserted into the groove 110, which enables the protrusion 232, together with the second substrate 231 and the connecting portion 220, to securely clamp the support member 10 in the pressing member 20.

[0079] Furthermore, since the second substrate 231 is a plate-shaped structure, it can better fit with the support member 10, thereby ensuring the contact area between the second mounting part 230 and the support member 10, and thus improving the support stability of the second mounting part 230 for the support member 10.

[0080] For example, the second substrate 231 is a rectangular plate. In other embodiments, the second substrate 231 may also be a plate of other shapes, such as triangles, rhombuses, etc. This disclosure does not limit it.

[0081] In this embodiment, the support member 10 is a plate-shaped structure. In this way, one surface of the support member 10 is in contact with the flexible display panel 100, thereby ensuring the contact area between the support member 10 and the flexible display panel 100, thus providing better support for the flexible display panel 100. The other surface of the support member 10 is in contact with the second substrate 231, thereby ensuring the contact area between the support member 10 and the second substrate 231, thus providing better support from the second substrate 231.

[0082] For example, the end of the protrusion 232 facing away from the second substrate 231 is arc-shaped, and the end of the protrusion 232 facing away from the second substrate 231 slides in contact with the bottom of the groove 110.

[0083] In the above implementation, the end of the protrusion 232 facing away from the second substrate 231 is arc-shaped, which can effectively reduce the friction between the protrusion 232 and the support member 10, so that the support member 10 can slide more smoothly relative to the second mounting part 230, thereby facilitating the switching of the pressing assembly between the unfolded state and the winding state.

[0084] Figure 8 This is a schematic diagram of the structure of a display device provided in an embodiment of the present disclosure. See also: Figure 8 In this embodiment, the display device includes a flexible display panel 100 and Figure 1-7 The pressure edge assembly shown.

[0085] The flexible display panel 100 is attached to the support member 10, and an outer edge of the flexible display panel 100 and an outer edge of the support member 10 are simultaneously inserted into the pressing member 20.

[0086] When the flexible display panel 100 is unfolded, the edge-pressing assembly is in the unfolded state (see...). Figure 2One side of the support member 10 is in contact with the flexible display panel 100, thereby providing stable support for the flexible display panel 100 and effectively strengthening its structural strength, preventing damage under external forces. Furthermore, the edge clamping member 20 secures the flexible display panel 100 and the support member 10 together, preventing the flexible display panel 100 from detaching from the support member 10 and further ensuring the support member 10's support for the flexible display panel 100. Additionally, when the flexible display panel 100 is rolled up, the edge clamping member is in the rolling state (see...). Figure 3 In this configuration, the support member 10 no longer supports the flexible display screen, while the edge pressing member 20 can be rolled up together with the flexible display panel 100. In this way, the edge pressing member will not affect the normal rolling up of the flexible display panel 100.

[0087] In other words, the display device provided in this embodiment of the present disclosure can have a stable structural strength in the unfolded state and can also be rolled up normally.

[0088] In this embodiment, one outer edge of the flexible display panel 100 and one outer edge of the support member 10 are simultaneously inserted into a portion of the pressing member 20, and the other opposite outer edge of the flexible display panel 100 and the other opposite outer edge of the support member 10 are simultaneously inserted into another portion of the pressing member 20.

[0089] In the above implementation, the flexible display panel 100 is supported by the support member 10, and both outer edges of the flexible display panel 100 are reinforced by the edge pressing members 20. In this way, the structural strength of the flexible display panel 100 can be better strengthened by the edge pressing members, further improving the reliability of the display device.

[0090] In this embodiment, the outer edge of the flexible display panel 100 located within the accommodating space 240 is flush with the outer edge of the support member 10 located within the accommodating space 240. This design facilitates the pressing member 20 in attaching the flexible display panel 100 to the support member 10.

[0091] Figure 9 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this disclosure. See also: Figure 8 In this embodiment, the electronic device includes a display device.

[0092] Because the electronic device includes Figure 8 The display device shown indicates that the electronic device has... Figure 8 The full benefits of the display device shown will not be elaborated here.

[0093] In this embodiment, the electronic device is a mobile phone, tablet computer, etc., and this disclosure does not limit it.

[0094] If the electronic device is a mobile phone, then it is a rollable phone. When the phone is in the rolled-up state, the display device is also in the rolled-up state. In this state, the phone is smaller and easier to hold. When the phone is in the unfolded state, the display device is also unfolded. In this state, the phone screen is larger and easier to view and operate.

[0095] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
