Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of display, and particularly relates to a display assembly, an electronic device and a manufacturing method of a support frame. BACKGROUND

[0002] With the rapid development of the electronic industry, electronic devices have a relatively wide range of application scenarios, and electronic devices also have a relatively diversified structure. Among them, foldable electronic devices that can be folded and unfolded have become an important development direction due to their novel structure, strong portability and strong storage convenience.

[0003] In the related art, a support frame is often provided in a foldable electronic device, which can be used to support a flexible screen and can be folded along with the flexible screen. Therefore, the support frame often needs to have good structural strength to provide good support effect, and the support frame also needs to have good bending performance to better follow the bending of the flexible screen. However, the support frame often cannot better combine structural strength and bending performance. SUMMARY

[0004] The present application aims to provide a display assembly, an electronic device and a manufacturing method of a support frame, at least solving the technical problem that the support frame cannot better combine structural strength and bending performance.

[0005] In order to solve the above technical problems, the present application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a display assembly, the display assembly comprising a flexible screen and a support frame, the flexible screen having a first bending portion, a second bending portion disposed on one side of the first bending portion, and a connecting portion between the first bending portion and the second bending portion; in a case where the flexible screen is in a bent state, a bending curvature of the first bending portion is greater than a bending curvature of the second bending portion; the support frame is used to support the flexible screen, the support frame comprising a support plate and a gel body, the support plate comprising opposite first and second surfaces, the support plate having a first region and a second region, the first region being opposite the first bending portion, the second region being opposite the second bending portion and the connecting portion, the first region being provided with a through hole penetrating and communicating the first and second surfaces; the gel body is disposed on the second surface of the second region, the gel body having a transition region and a pattern region, the transition region being opposite the connecting portion, the pattern region being opposite the second bending portion, a thickness of at least part of the gel body in the pattern region being less than a thickness of the gel body in the transition region.

[0007] In a second aspect, the present application further provides an electronic device, the electronic device comprising a flexible screen and a display assembly as provided in the first aspect.

[0008] In a third aspect, the present application further provides a manufacturing method of a support frame, the manufacturing method comprising:

[0009] etching a support plate to be prepared to form a support plate, the support plate comprising a first surface and a second surface opposite to each other, the support plate having a first region and a second region arranged on both sides of the first region, the first region being provided with a through hole penetrating through the first surface and the second surface;

[0010] a gel is formed by coating a gel material on the second surface, the material of the gel comprising a conductive material, the gel having a transition region, a pattern region located on a side of the transition region away from the first region, and a non-pattern region located on a side of the pattern region away from the transition region, the thickness of the gel located at least partially in the pattern region being less than the thickness of the gel located in the transition region and / or the non-pattern region.

[0011] In the display assembly provided in the present application, the flexible screen has a first bending part, a second bending part arranged on one side of the first bending part, and a connecting part located between the first bending part and the second bending part. When the flexible screen is in a bent state, the bending curvature of the first bending part is greater than the bending curvature of the second bending part, so that the flexible screen can be bent and deformed in a "water drop shape". That is, the main bending deformation of the flexible screen occurs at the first bending part, the secondary bending deformation of the flexible screen occurs at the second bending part, and the bending deformation amount of the flexible screen at the connecting part is small. The support frame is used to support the flexible screen, and the support frame comprises a support plate and a gel. The support plate comprises a first surface and a second surface opposite to each other. The first surface can be used to connect with the flexible screen and provide a supporting effect to the flexible screen. The support plate has a first region and a second region. The first region is opposite to the first bending part to provide a supporting effect to the first bending part. The second region is opposite to the second bending part and the connecting part to provide a supporting effect to the second bending part. The first region is provided with a through hole penetrating through the first surface and the second surface of the support plate, so as to improve the bending ability of the first region in the support plate. When the support plate is folded or unfolded with the flexible screen, the second regions located on both sides of the first region in the support plate can move close to each other to realize bending, or move away from each other to realize unfolding. The gel can be used to bond some reinforcing members with the support plate. By arranging the gel on the second surface of the second region, the bending influence of the gel on the first bending part of the flexible screen and the first region of the support plate is reduced. The gel has a transition region and a pattern region. The transition region is opposite to the connecting part, and the pattern region is opposite to the second bending part. The gel located in the transition region can provide a better supporting and reinforcing effect to the support plate opposite to the connecting part, so that the support plate at this position can have a better structural strength to better support the connecting part of the flexible screen. By arranging the thickness of the gel located at least partially in the pattern region to be less than the thickness of the gel located in the transition region, the gel located in the pattern region can not easily affect the bending of the support plate opposite to the second bending part, so as to improve the bending effect of the support plate at this position and the flexible screen at the second bending part.

[0032] The features and exemplary embodiments of various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely intended to explain the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details, which are well known to those skilled in the art. The following description of the embodiments is merely provided to give a better understanding of the present application by showing examples of the present application, and in the drawings and the following description, at least some of the well-known structures and techniques are not shown in order to avoid unnecessary obscuring of the present application; and, for clarity, the size of some of the structures can be exaggerated. In addition, the features, structures or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0033] It should be noted that, in this article, unless otherwise stated, the meaning of "a plurality" is more than two; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0034] The orientation words appearing in the following description are the directions shown in the figures, and are not specific structures of the embodiments of the present application. In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be direct connection, or indirect connection. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] With the rapid development of the electronic industry, electronic devices have a relatively wide range of application scenarios, and electronic devices also have a relatively diversified structure. Among them, the foldable electronic device which can be folded and unfolded has the characteristics of novel structure, strong portability and strong storage, so the design of the foldable electronic device has become an important development direction. In the related art, a support frame is often provided in the foldable electronic device, which can be used to support the flexible screen and can be folded with the flexible screen, so the support frame often needs to have good structural strength to provide good support effect, and the support frame also needs to have good bending performance to better follow the bending of the flexible screen.

[0036] However, the applicant has found that in the prior art, the support plate of the support frame often needs to be punched to make the support frame have better bending performance, but the punching process reduces the strength of the support plate and thus reduces the overall structural strength of the support frame. For example, when the material of the support plate is carbon fiber material, it is difficult to form a blind hole in the carbon fiber material, so a through hole is often formed in the support plate to make the support frame have better bending performance, which greatly reduces the structural strength of the support frame and makes the support frame prone to deformation when bent. Therefore, the support frame often cannot have both good structural strength and bending performance.

[0037] To solve the above technical problems, the present application is provided. In order to better understand the present application, the display assembly, the electronic device and the manufacturing method of the support frame of the embodiments of the present application are described in detail below with reference to the drawings.

[0038] Figure 1 FIG. 1 is a structural schematic diagram of a support frame 10 according to some embodiments of the present application, Figure 2 FIG. 2 is a partial cross-sectional schematic diagram of a display assembly according to some embodiments of the present application, Figure 3 FIG. 3 is a partial cross-sectional schematic diagram of a display assembly according to other embodiments of the present application.

[0039] As Figures 1 to 3 shown, the embodiments of the present application provide a display assembly, which comprises a flexible screen 20 and a support frame 10. The flexible screen 20 has a first bending part 20a, a second bending part 20b located on one side of the first bending part 20a, and a connecting part 20c located between the first bending part 20a and the second bending part 20b. In the case that the flexible screen 20 is in a bent state, the bending curvature of the first bending part 20a is greater than that of the second bending part 20b. The support frame 10 is used to support the flexible screen 20. The support frame 10 comprises a support plate 1 and a gel 2. The support plate 1 comprises opposite first and second surfaces 13 and 14. The support plate 1 has a first region 11 and a second region 12. The first region 11 is opposite to the first bending part 20a, and the second region 12 is opposite to the second bending part 20b and the connecting part 20c. The first region 11 is provided with a through hole 15 that penetrates through the first and second surfaces 13 and 14. The gel 2 is arranged on the second surface 14 of the second region 12. The gel 2 has a transition area 21 and a pattern area 22. The transition area 21 is opposite to the connecting part 20c, and the pattern area 22 is opposite to the second bending part 20b. The thickness of the gel 2 located in at least part of the pattern area 22 is less than the thickness of the gel 2 located in the transition area 21.

[0040] In the display assembly provided in the application, the flexible screen 20 has a first bending part 20a, a second bending part 20b arranged on one side of the first bending part 20a, and a connecting part 20c between the first bending part 20a and the second bending part 20b. When the flexible screen 20 is in a bending state, the bending curvature of the first bending part 20a is greater than the bending curvature of the second bending part 20b, that is, the flexible screen 20 mainly bends at the first bending part 20a, and the flexible screen 20 secondarily bends at the second bending part 20b.

[0041] Optionally, the bending curvature of the connecting part 20c can be less than the bending curvature of the second bending part 20b. In this way, the bending deformation of the flexible screen 20 at the connecting part 20c is small.

[0042] Optionally, the flexible screen 20 can include at least two second bending parts 20b, and the number of the connecting parts 20c can also be at least two. The at least two second bending parts 20b can be arranged on opposite sides of the first bending part 20a, and each connecting part 20c can be arranged between the first bending part 20a and the second bending part 20b. When the flexible screen 20 deforms from an unfolded state to a bending state, that is, when the first bending part 20a bends, the second bending parts 20b and the connecting parts 20c on both sides of the first bending part 20a approach each other to achieve folding. When the flexible screen 20 deforms from a bending state to an unfolded state, that is, when the first bending part 20a gradually unfolds, the second bending parts 20b and the connecting parts 20c on both sides of the first bending part 20a move away from each other to achieve unfolding.

[0043] Optionally, in the case that the flexible screen 20 is in a bending state, the first bending part 20a can bend towards a side away from the support frame 10, and the second bending part 20b can bend towards a side close to the support frame 10. In this way, in the case that the flexible screen 20 is in a bending state, the flexible screen 20 can bend and deform in a "water drop shape", so that the flexible screen 20 can have a better bending stress distribution in the bending state.

[0044] The support frame 10 is used for supporting the flexible screen 20. The support frame 10 includes a support plate 1 and a glue body 2. The support plate 1 includes a first surface 13 and a second surface 14 opposite to each other. The first surface 13 can be used for connecting with the flexible screen 20 and providing a supporting action to the flexible screen 20.

[0045] The support plate 1 has a first region 11 opposite to the first bending part 20a to provide support to the first bending part 20a, and a second region 12 opposite to the second bending part 20b and the connecting part 20c to provide support to the second bending part 20b. The first region 11 is provided with a through hole 15 penetrating the first surface 13 and the second surface 14 of the support plate 1 to improve the bending capability of the first region 11 of the support plate 1, so that the second region 12 on both sides of the first region 11 of the support plate 1 can deform to approach each other to realize bending or move away from each other to realize unfolding when the support plate 1 is folded or unfolded with the flexible screen 20.

[0046] The glue 2 can be used to bond some reinforcing members 3 with the support plate 1. The glue 2 is arranged on the second surface 14 of the second region 12 to reduce the bending influence of the glue 2 on the first bending part 20a of the flexible screen 20 and the first region 11 of the support plate 1. The glue 2 has a transition region 21 opposite to the connecting part 20c and a pattern region 22 opposite to the second bending part 20b. The glue 2 in the transition region 21 can provide better support and reinforcement to the support plate 1 opposite to the connecting part 20c, so that the support plate 1 at this position can have better structural strength to better support the connecting part 20c of the flexible screen 20.

[0047] The thickness of the glue 2 in the pattern region 22 is less than the thickness of the glue 2 in the transition region 21, so that the glue 2 in the pattern region 22 can not easily affect the bending of the support plate 1 opposite to the second bending part 20b, to improve the bending effect of the support plate 1 at this position and the flexible screen 20 at the second bending part 20b.

[0048] In the embodiments of the present application, the first region 11 opposite to the first bending part 20a can mean that the projection of the first region 11 is located in the projection of the first bending part 20a or the projection of the first region 11 overlaps the projection of the first bending part 20a in the direction from the first surface 13 to the second surface 14. The second region 12 opposite to the second bending part 20b and the connecting part 20c can mean that the projection of the second region 12 is located in the projection of the second bending part 20b and the connecting part 20c or the projection of the second region 12 overlaps the projection of the second bending part 20b and the connecting part 20c in the direction from the first surface 13 to the second surface 14.

[0049] The transition region 21 is opposite to the connecting portion 20c, which can mean that, in the direction from the first surface 13 to the second surface 14, the projection of the transition region 21 is located within the projection of the connecting portion 20c, or the projection of the transition region 21 overlaps with the projection of the connecting portion 20c. The pattern region 22 is opposite to the second bending portion 20b, which can mean that, in the direction from the first surface 13 to the second surface 14, the projection of the pattern region 22 is located within the projection of the second bending portion 20b, or the projection of the pattern region 22 overlaps with the projection of the second bending portion 20b.

[0050] The support plate 1 and the material of the colloid 2 can be arranged in various manners. In some embodiments, the material of the colloid 2 can include a conductive material, and / or the material of the support plate 1 can include a carbon fiber material, which has the advantages of small density, light mass, and high structural strength. In some embodiments, when the material of the support plate 1 includes a carbon fiber material, the support frame 10 is prone to have an ESD (Electro-Static discharge) problem when applied to an electronic device. By arranging the material of the colloid 2 to include a conductive material, the possibility of the ESD problem in the electronic device can be reduced. Alternatively, the colloid 2 can be a conductive glue.

[0051] In some alternative embodiments, the first region 11 and the second region 12 can be formed to extend along the length direction of the flexible screen 20. The length direction can be the extension direction of an axis around which the flexible screen 20 is bent and deformed. Alternatively, the extension sizes of the first region 11 and the second region 12 along the length direction can be equal.

[0052] The shape, extension size, and number of the through hole 15 are not limited in the present application. Alternatively, at least part of the through hole 15 can be formed to extend along the length direction. Alternatively, the extension size of the through hole 15 along the length direction can be less than or equal to the extension size of the first region 11 along the length direction. Alternatively, the number of the through hole 15 can be one or more. For example, when the through hole 15 is multiple, at least part of the through holes 15 can be arranged in parallel.

[0053] In some optional embodiments, the dimensions of the second bending portion 20b and the connecting portion 20c can be configured in various ways. Similarly, the dimensions of the second region 12 can be configured in various ways. Optionally, the dimensions of the second bending portion 20b and the connecting portion 20c located on both sides of the first bending portion 20a can be the same, that is, the second bending portion 20b can be symmetrically disposed on both sides of the first bending portion 20a, and the connecting portion 20c can be symmetrically disposed on both sides of the first bending portion 20a. Similarly, the dimensions of the second region 12 located on both sides of the first region 11 can also be the same, that is, the second region 12 can be symmetrically disposed on both sides of the first region 11, so that when the first bending portion 20a and the support plate 1 located in the first region 11 undergo bending deformation, the flexible screen 20 and the support plate 1 can be folded in a relatively symmetrical manner.

[0054] Optionally, the dimensions of the second bending portion 20b and the connecting portion 20c located on both sides of the first bending portion 20a can be different. That is, the second bending portion 20b can be asymmetrically distributed on both sides of the first bending portion 20a, and the connecting portion 20c can also be asymmetrically distributed on both sides of the first bending portion 20a. Similarly, the dimensions of the second region 12 located on both sides of the first region 11 can also be different. That is, the second region 12 can be asymmetrically distributed on both sides of the first region 11, so that when the first bending portion 20a and the support plate 1 located in the first region 11 undergo bending deformation, the flexible screen 20 and the support plate 1 can be folded asymmetrically.

[0055] Optionally, the second region 12 of the support plate 1 may include a first sub-region 121 opposite to the connecting portion 20c and a second sub-region 122 opposite to the second bending portion 20b. When the support plate 1 bends with the flexible screen 20, the main bending deformation of the support plate 1 may occur in the support plate 1 located in the first region 11, and the less significant bending deformation of the support plate 1 may occur in the support plate 1 located in the second sub-region 122. The bending deformation of the support plate 1 located in other regions is smaller. That is, the degree of bending deformation of the support plate 1 located in the first region 11 is greater than the degree of bending deformation of the support plate 1 located in the second sub-region 122, and the degree of bending deformation of the support plate 1 located in the second sub-region 122 is greater than the degree of bending deformation of the support plate 1 located in other regions.

[0056] For example, when support plate 1 bends, such as Figure 2 As shown, the support plate 1 located in the first region 11, the first sub-region 121 and the second sub-region 122 can be bent and deformed into a "teardrop shape" to achieve the bending deformation of the support frame 10. The support plate 1 located in the first region 11 undergoes the main bending deformation, the support plate 1 located in the second sub-region 122 undergoes the secondary bending deformation, and the support plate 1 located in the first sub-region 121 undergoes the smaller bending deformation.

[0057] In the optional embodiments, the gel 2 located at the transition region 21 can be connected with the second surface 14 of the support plate 1 located at the first sub-region 121, so that the gel 2 located at the transition region 21 can provide better support and strengthening effect to the support plate 1 located at the first sub-region 121, and the support plate 1 located at the first sub-region 121 can have better structural strength to better support the connecting portion 20c of the flexible screen 20.

[0058] The gel 2 located at the pattern region 22 can be connected with the second surface 14 of the support plate 1 located at the second sub-region 122, so that the gel 2 located at the pattern region 22 can not easily affect the bending deformation of the support plate 1 located at the first sub-region 121, to improve the bendable capability of the support plate 1 located at the first sub-region 121, so that the second bending portion 20b of the flexible screen 20 has better bendable capability.

[0059] In some optional embodiments, the gel 2 can further have a non-pattern region 23 located at the side of the pattern region 22 away from the transition region 21, and the flexible screen 20 can further have a non-bending portion 20d located at the side of the second bending portion 20b away from the first bending portion 20a, and when the flexible screen 20 is in the bending state, the non-bending portion 20d of the flexible screen 20 can not be bent and deformed. The non-pattern region 23 is opposite to the non-bending portion 20d, that is, in the direction from the first surface 13 to the second surface 14, the projection of the non-pattern region 23 is located within the projection of the non-bending portion 20d, or the projection of the non-pattern region 23 overlaps with the projection of the non-bending portion 20d. The support frame 10 further comprises a reinforcing member 3 connected to the side of the gel 2 away from the support plate 1, and the reinforcing member 3 can provide better support to the support plate 1 to improve the structural strength of the support frame 10 as a whole, so that the support frame 10 can provide better support to the non-bending portion 20d of the flexible screen 20. The thickness of the gel 2 located at the non-pattern region 23 can be greater than or equal to the thickness of the gel 2 located at the transition region 21, the gel 2 located at the non-pattern region 23 can provide better support to the support plate 1, and the gel 2 located at the non-pattern region 23 can be used to bond the reinforcing member 3 and the support plate 1. While the gels 2 located at the pattern region 22 and the transition region 21 can not be bonded with the reinforcing member 3, that is, the gels 2 located at the pattern region 22 and the transition region 21 can only be used to adjust the structural strength and bending capability of the support frame 10.

[0060] Optionally, the second region 12 further comprises a third sub-region 123 located at the side of the second sub-region 122 away from the first sub-region 121, that is, the third sub-region 123 is opposite to the non-bending portion 20d and the non-pattern region 23, and the gel 2 located at the non-pattern region 23 can be connected with the support plate located at the third sub-region 123, and when the support frame 10 is bent, the bending deformation of the support plate 1 located at the third sub-region 123 is smaller.

[0061] The reinforcing member 3 may include an aluminum sheet 31 and a gasket 32 ​​stacked in a direction away from the colloid 2. That is, the support frame 10 also includes an aluminum sheet 31 located on the side of the non-patterned area 23 away from the support plate 1 and a gasket 32 ​​located on the side of the aluminum sheet 31 away from the colloid 2, so as to improve the overall structural strength of the support frame 10. The aluminum sheet 31 can be connected to the colloid 2 located in the non-patterned area 23 by a mesh adhesive 33. That is, the orthographic projection of the aluminum sheet 31 on the support plate 1 is located in the third sub-region 123, so as to reduce the interference of the aluminum sheet 31 on the support plate 1 when it is bent. The orthographic projection of the gasket 32 ​​on the support plate 1 may be located in the first region 11 or the second region 12, so as to improve the overall structural strength of the support frame 10, so that the support frame 10 can provide better support for the flexible screen 20.

[0062] Optionally, the support frame 10 also includes a Mylar 4, which is connected to the side of the support plate 1 facing the pad 32. The orthographic projection of the Mylar 4 on the support plate 1 is located within the first region 11, and at least part of the orthographic projection of the through hole 15 on the support plate 1 is located within the orthographic projection of the Mylar 4 on the support plate 1. This allows the Mylar 4 to be used to restrict dust from passing through the through hole 15, thereby reducing the impact of dust on the operation of the flexible screen 20.

[0063] Optionally, foam 5 is provided on the side of the support plate 1 facing the flexible screen 20, that is, foam 5 can be provided between the support plate 1 and the flexible screen 20. Foam 5 can play a buffering role so that the flexible screen 20 is not easily damaged after being impacted or collided.

[0064] Optionally, the colloid 2 may have a top surface on the side opposite to the support plate 1. The thickness of the colloid 2 described in this embodiment may refer to the minimum distance between the top surface and the support plate 1. The specific thickness of the colloid 2 can be set according to the structure and size of the support plate 1. Optionally, the thickness of the colloid 2 may be from 0 micrometers to 200 micrometers.

[0065] In some optional embodiments, the thickness of the colloid 2 located in the pattern area 22 can be set in various ways. In some embodiments, the thickness of the colloid 2 located in the pattern area 22 can be less than or equal to the thickness of the colloid 2 located in the transition area 21, so as to reduce the influence of the overall colloid 2 located in the pattern area 22 on the bending deformation of the support plate 1 located in the second sub-region 122, thereby improving the bending ability of the support frame 10, so that the flexible screen 20 can be bent more easily at the second bending portion 20b.

[0066] like Figure 2 and Figure 3 As shown, in some embodiments, the thickness of the colloid 2 located in the patterned area 22 may be equal to 0, so as to reduce the influence of the colloid 2 located in the patterned area 22 on the bending deformation of the support plate 1 located in the second sub-region 122, thereby improving the bending capacity of the support frame 10.

[0067] Figure 4 A partial sectional view of a display assembly according to some embodiments of the present application.

[0068] As shown in FIG. 1, in some embodiments, the pattern region 22 can include a plurality of first pattern regions 221 and a plurality of second pattern regions 222, and the plurality of second pattern regions 222 are arranged at intervals in the direction from the first region 11 to the pattern region 22, and the first pattern regions 221 are located between two adjacent second pattern regions 222 and / or the first pattern regions 221 are located between the adjacent second pattern regions 222 and the transition region 21, wherein the thickness of the gel 2 located in the second pattern region 222 is greater than the thickness of the gel 2 located in the first pattern region 221. Figure 4 The gel 2 located in the second pattern region 222 has a certain thickness, so that the gel 2 located in the second pattern region 222 can provide better support to the support plate 1 connected thereto, and the gel 2 located in the first pattern region 221 is less likely to affect the bending of the flexible screen 20 and the support plate 1 due to the smaller thickness, thereby improving the bendable capability of the flexible screen 20 and the support frame 10.

[0069] By arranging the plurality of first pattern regions 221 and the plurality of second pattern regions 222, the structural strength and the bendable performance of the support frame 10 corresponding to the pattern region 22 can be better adjusted and balanced, so that the support frame 10 can better balance the structural strength and the bendable performance.

[0070] The thickness of the gel 2 located in the first pattern region 221 and the second pattern region 222 can be arranged in various ways. Optionally, the thickness of the gel 2 located in the first pattern region 221 can be equal to 0, so as to reduce the influence of the gel 2 located in the pattern region 22 on the bending deformation of the support plate 1 located in the second sub-region 122, thereby improving the bending capability of the support frame 10. Optionally, the thickness of the gel 2 located in the second pattern region 222 can be greater than the thickness of the gel 2 located in the first pattern region 221, and the thickness of the gel 2 located in the second pattern region 222 can be less than or equal to the thickness of the gel 2 located in the transition region 21, so that the gel 2 located in the second pattern region 222 can provide better support and strengthening effect to the support plate 1.

[0071] As shown in FIG. 1, in some embodiments, the pattern region 22 can include a plurality of first pattern regions 221 and a plurality of second pattern regions 222, and the plurality of second pattern regions 222 are arranged at intervals in the direction from the first region 11 to the pattern region 22, and the first pattern regions 221 are located between two adjacent second pattern regions 222 and / or the first pattern regions 221 are located between the adjacent second pattern regions 222 and the transition region 21, wherein the thickness of the gel 2 located in the second pattern region 222 is greater than the thickness of the gel 2 located in the first pattern region 221. Figure 4In some embodiments, the gel 2 in the transition region 21 includes a first body portion 21a and a first end portion 21b located on a side of the first body portion 21a facing the pattern region 22, and the thickness of the first end portion 21b gradually decreases in a direction from the first region 11 to the pattern region 22. By gradually decreasing the thickness of the first end portion 21b, the bending deformation transition of the first end portion 21b and the support plate 1 corresponding to the first end portion 21b can be more uniform when the support plate 1 is bent, which is conducive to uniform stress when the support plate 1 is bent, and the gel 2 and the support plate 1 are less likely to separate.

[0072] Optionally, the gel 2 in the transition region 21 further includes a side end 21c located on a side of the first body portion 21a facing the first region 11, and the thickness of the side end 21c gradually decreases in a direction from the first body portion 21a to the first region 11. By gradually decreasing the thickness of the side end 21c, the bending deformation transition of the side end 21c and the support plate 1 corresponding to the side end 21c can be more uniform when the support plate 1 is bent, which is conducive to uniform stress when the support plate 1 is bent, and the gel 2 and the support plate 1 are less likely to separate.

[0073] In some embodiments, the gel 2 in the second pattern region 222 includes a second body portion 222a and a second end portion 222b located on a side of the second body portion 222a facing the first pattern region 221, and the thickness of the second end portion 222b gradually decreases in a direction from the second body portion 222a to the first pattern region 221. By gradually decreasing the thickness of the second end portion 222b, the bending deformation transition of the second end portion 222b and the support plate 1 corresponding to the second end portion 222b can be more uniform when the support plate 1 is bent, which is conducive to uniform stress when the support plate 1 is bent, and the gel 2 and the support plate 1 are less likely to separate.

[0074] Optionally, the gel 2 in the non-pattern region 23 includes a third body portion 23a and a third end portion 23b located on a side of the third body portion 23a facing the pattern region 22, and the thickness of the third end portion 23b gradually decreases in a direction from the pattern region 22 to the third body portion 23a. By gradually decreasing the thickness of the third end portion 23b, the bending deformation transition of the third end portion 23b and the support plate 1 corresponding to the third end portion 23b can be more uniform when the support plate 1 is bent, which is conducive to uniform stress when the support plate 1 is bent, and the gel 2 and the support plate 1 are less likely to separate.

[0075] In the optional embodiments, the first pattern area 221 and the second pattern area 222 can be arranged in various ways in terms of width, i.e. the width of the glue 2 located in the first pattern area 221 and the width of the glue 2 located in the second pattern area 222, wherein the width of the first pattern area 221 can refer to the maximum extension of the first pattern area 221 in the direction from the first area 11 to the pattern area 22. The width of the second pattern area 222 can refer to the maximum extension of the second pattern area 222 in the direction from the first area 11 to the pattern area 22.

[0076] Optionally, the width of the first pattern area 221 can be equal to the width of the glue 2 located in the first pattern area 221, and optionally, the width of the second pattern area 222 can be equal to the width of the glue 2 located in the second pattern area 222.

[0077] Figure 5 A partial structure diagram of the glue 2 for some embodiments of the present application is shown in FIG. 6A. Figure 6 A partial structure diagram of the glue 2 for some other embodiments of the present application is shown in FIG. 6B. Figure 7 A partial structure diagram of the glue 2 for some other embodiments of the present application is shown in FIG. 6C.

[0078] In some embodiments, in the direction away from the transition area 21, the width of the first pattern area 221 gradually decreases, as shown in FIG. 6A; or, the width of the first pattern area 221 gradually increases, as shown in FIG. 6B; or, the width of the first pattern area 221 is equal, as shown in FIG. 6C. Figure 5 Figure 6 Figure 7

[0079] Preferably, in the direction away from the transition area 21, the width of the first pattern area 221 gradually increases. Since the flexible screen 20 is in a “water drop shape” in the bent state, i.e. the second bent part 20b is bent towards the side close to the support frame 10, the second sub-area 122 opposite to the second bent part 20b on the support frame 10 will also be bent towards the side away from the flexible screen 20, and the bending deformation amount at the second sub-area 122 away from the first sub-area 121 is larger, therefore, by arranging the width of the first pattern area 221 gradually increasing in the direction away from the transition area 21, the first pattern area 221 can play a better role in giving way to the bending of the second sub-area 122 towards the side away from the flexible screen 20, thereby improving the bending reliability of the support frame 10.

[0080] Optionally, the width of the first pattern area 221 can be 1-10 mm.

[0081] Figure 8 A partial structure diagram of the glue 2 for some other embodiments of the present application is shown in FIG. 6B. Figure 9 A partial structure diagram of the glue 2 for some other embodiments of the present application is shown in FIG. 6C.​​​

[0082] In some embodiments, in the direction away from transition region 21, such as Figure 8 As shown, the width of the second pattern area 222 gradually decreases; or, as... Figure 9 As shown, the width of the second pattern area 222 gradually increases; or, the width of the second pattern area 222 is equal.

[0083] Preferably, the width of the second pattern area 222 gradually increases in the direction away from the transition area 21, so that the bending deformation transition between the support plate 1 and the colloid 2 can be more uniform, thereby improving the bending reliability of the support frame 10.

[0084] Optionally, the width of the second pattern area 222 may be greater than or equal to the width of the first pattern area 221. Optionally, the width of the second pattern area 222 may be from 1 mm to 20 mm. Optionally, the width of the transition area 21 may be greater than the width of the second pattern area 222.

[0086] Since the electronic device provided in this application includes the display component of any of the above embodiments, the electronic device provided in this application can have the beneficial effects of the display component of any of the above embodiments, which will not be repeated here.

[0087] Figure 10 This is a schematic flowchart of a method for preparing a support frame 10 according to some embodiments of this application.

Please refer to... Figures 1 to 9 And see Figure 10 As shown, the manufacturing method includes:

[0089] Step S01: The support plate 1 to be prepared is etched to form the support plate 1. The support plate 1 includes a first surface 13 and a second surface 14 facing away from each other. The support plate 1 has a first region 11 and a second region 12 disposed on both sides of the first region 11. The first region 11 is provided with a through hole 15 that connects the first surface 13 and the second surface 14.

[0090] The first region 11 is provided with a through hole 15 penetrating through the first surface 13 and the second surface 14 of the support plate 1, so as to improve the bending capability of the first region 11 of the support plate 1, and when the support plate 1 is folded or unfolded along with the flexible screen 20, the second regions 12 on both sides of the first region 11 of the support plate 1 can deform along with the bending of the first region 11 to approach each other to realize folding, or move away from each other to realize unfolding.

[0091] Step S02: The gel material is coated on the second surface 14 to form a gel 2, the material of the gel 2 includes conductive material, the gel 2 has a transition region 21, a pattern region 22 located on the side of the transition region 21 away from the first region 11, and a non-pattern region 23 located on the side of the pattern region 22 away from the transition region 21, and the thickness of the gel 2 located at least partially in the pattern region 22 is less than the thickness of the gel 2 located in the transition region 21 and / or the non-pattern region 23.

[0092] The first region 11 is located in the interval between the gel materials, that is, the second surface 14 of the first region 11 can not be coated with the gel material.

[0093] The gel 2 can be used to bond some reinforcing members 3 with the support plate 1 to improve the structural strength of the support frame 10, and the gel 2 is connected to the second surface 14 of the second region 12 to reduce the bending influence of the gel 2 on the first region 11 of the support plate 1. The gel 2 located in the transition region 21 can provide better support and reinforcement to the support plate 1 connected thereto, so that the support plate 1 at this position can have better structural strength to better support the flexible screen 20. By setting the thickness of the gel 2 located at least partially in the pattern region 22 to be less than the thickness of the gel 2 located in the transition region 21, the gel 2 located in the pattern region 22 can not easily affect the bending of the support plate 1 connected thereto, so as to improve the bending effect of the support plate 1 at this position.

[0094] Optionally, after the gel material is coated on the second surface 14, the gel material can be further scraped and cured to form the gel 2. The thickness and width of each region of the gel 2 can be adjusted by reasonably setting the interval between the gel materials when the gel material is coated and reasonably setting the degree of scraping treatment of the gel material.

[0096] Step S03: connecting the Mylar 4 to the support plate 1 on a side of the support plate 1 facing the gasket 32, wherein the orthographic projection of the Mylar 4 on the support plate 1 is located in the first region 11, and the orthographic projection of at least part of the through hole 15 on the support plate 1 is located in the orthographic projection of the Mylar 4 on the support plate 1.

[0097] By arranging the Mylar 4 on the side of the support plate 1 facing the gasket 32, the Mylar 4 can be used to limit the dust passing through the through hole 15, thereby reducing the influence of dust on the operation of the flexible screen 20.

[0098] In some embodiments, the manufacturing method can further include, after step S02:

[0099] Step S04: the adhesive 2 can further have a non-patterned region 23 located on a side of the patterned region 22 facing away from the transition region 21, and the aluminum sheet 31 is connected to the support plate 1 on a side of the adhesive 2 located in the non-patterned region 23 facing away from the support plate 1, wherein the second region 12 further includes a third sub-region 123 located on a side of the second sub-region 122 facing away from the first sub-region 121, and the orthographic projection of the aluminum sheet 31 on the support plate 1 is located in the third sub-region 123.

[0100] Optionally, the thickness of the adhesive 2 in the first patterned region 221 can be equal to 0. Optionally, when the adhesive material is spaced apart on the second surface 14, the space without the adhesive material can be used to form the first patterned region 221. While the position with the adhesive material can be used to form the non-patterned region 23, the second patterned region, and the transition region.

[0101] The aluminum sheet 31 can improve the overall structural strength of the support frame 10, and the aluminum sheet 31 is not easy to interfere with the bending of the support plate 1. Optionally, the aluminum sheet 31 can be bonded to the adhesive 2 through the grid adhesive 33.

[0102] In some embodiments, the manufacturing method can further include, after step S02:

[0103] Step S05: connecting the gasket 32 to the aluminum sheet 31 on a side of the aluminum sheet 31 facing away from the adhesive 2, wherein the orthographic projection of the gasket 32 on the support plate 1 can be located in the first region 11 and the second region 12.

[0104] The gasket 32 is connected to the aluminum sheet 31 on the side away from the colloid 2, so as to improve the structural strength of the support frame 10 as a whole.
