Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a support member, a flexible screen assembly, and an electronic device. Background Technology

[0002] With the development of electronic technology, flexible displays have enabled electronic devices such as smartphones to have new product forms, such as foldable devices. However, after repeated folding during use, existing flexible displays are prone to developing creases in the bending areas, affecting their performance. Summary of the Invention

[0003] This application provides a support member, a flexible screen assembly, and an electronic device. The support member has suitable rigidity, which can not only support the flexible display screen well, but also make the flexible display screen less prone to creases after folding and bending.

[0004] In a first aspect, this application provides a support member, including a curved portion bent along an axis and support portions located on both sides of the curved portion. The curved portion is provided with a plurality of through holes spaced apart. The plurality of through holes are arranged according to a preset rule so that the curved portion forms at least one rib along a first direction, the first direction being perpendicular to the axis.

[0005] Secondly, this application also provides a flexible screen assembly, comprising:

[0006] A flexible display screen includes a curved region and non-curved regions located on either side of the curved region; and

[0007] A support member, as described above, is disposed on the non-display side of the flexible display screen, with the curved portion of the support member disposed relative to the curved area and the supporting portion of the support member disposed relative to the non-curved area.

[0008] Thirdly, this application also provides an electronic device, including the flexible screen assembly described above.

[0009] The support member, flexible screen assembly, and electronic device of this application have multiple through holes spaced apart within the curved portion of the support member, arranged according to a preset rule. This allows the curved portion to form at least one rib along a first direction, which can be perpendicular to the axis. Based on this, the support member of this application, on the one hand, the multiple through holes can weaken the rigidity of the curved portion, making it easier to fold and bend; on the other hand, the rib along the first direction can provide a certain rigidity to the curved portion to support the flexible display screen. Therefore, the curved portion of this application can weaken its rigidity, allowing the support member to have sufficient rigidity to support the flexible display screen in a folded state, while also preventing excessive rigidity in the curved portion from causing creases on the screen when the flexible screen is bent. The support member of this application can form a more favorable teardrop shape, supporting the flexible display screen to form a more favorable teardrop shape without creases.

[0022] The following will refer to the appendices in the embodiments of this application. Figure 1 To be continued Figure 11 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] This application provides a support member 120 and a flexible screen assembly 100. Please refer to... Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a flexible screen assembly 100 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows another configuration of the flexible screen assembly 100. The flexible screen assembly 100 may include a flexible display screen 110 and a support member 120.

[0024] The flexible display screen 110 can form a display surface for displaying images, text, and other information. The flexible display screen 110 may include an Organic Light-Emitting Diode (OLED) display. The flexible display screen 110 may include a display side and a non-display side. The display side is the side where the display surface of the flexible display screen 110 is located, and the user can view the information displayed on the flexible display screen 110 from the display side. The non-display side is positioned opposite the display side, and the user cannot view the information displayed on the flexible display screen 110 from the non-display side. The flexible display screen 110 may include a curved region 111 bent along a centerline L0 and non-curved regions 112 located on both sides of the curved region 111, such as a first non-curved region 1121 and a second non-curved region 1122, which can be sequentially connected. It is understandable that the axis L0 (a straight line around which an object or a three-dimensional graphic rotates or can be imagined to rotate) can be the axis of the flexible screen assembly 100 (e.g., flexible display screen 110 or support 120) when it undergoes shape movement changes.

[0025] The support member 120 can be disposed on the non-display side of the flexible display screen 110 to support the flexible display screen 110. The support member 120 can be connected to the flexible display screen 110 to both support the flexible display screen 110 and move synchronously with it. Of course, the support member 120 can also be not connected to the flexible display screen 110 but only support it. In this case, the support member 120 can be connected to a drive mechanism (such as, but not limited to, a rotating shaft) that drives the flexible display screen 110 to move, and the support member 120 can also achieve synchronous movement with the flexible display screen 110. The support member 120 may include a bent portion 121 bent along the axis L0 and support portions 122 located on both sides of the bent portion 121, such as a first support portion 1221 and a second support portion 1222. The first support portion 1221, the curved portion 121, and the second support portion 1222 can be connected sequentially. The curved portion 121 can be disposed relative to the curved area 111 of the flexible display screen 110, and the support portion 122 can be disposed relative to the non-curved area 112 of the flexible display screen 110. For example, the first support portion 1221 can be disposed relative to the first non-curved area 1121, and the second support portion 1222 can be disposed relative to the second non-curved area 1122.

[0026] It is understandable that the shapes of the support member 120 and the flexible display screen 110 can change. The bending portion 121 and the bending area 111 refer to the areas that can bend and deform during the movement of the flexible display screen 110 and the support member 120; correspondingly, the support portion 122 and the non-bending area 112 refer to the areas that do not bend and deform during the movement of the flexible display screen 110 and the support member 120, and the support portion 122 and the non-bending area 112 can be parallel to the axis L0.

[0027] For example, such as Figure 1 As shown, the flexible screen assembly 100 can be in an unfolded state. The two ends of the flexible display screen 110 can be on the same plane or approximately on the same plane. The curved region 111 and the non-curved region 112 of the flexible display screen 110 can also be on or approximately on the same plane. The curved region 111 and the non-curved region 112 of the flexible display screen 110 can be parallel to or approximately parallel to the axis L0. The entire flexible display screen 110 can display information. The support member 120 can be in an unfolded state along with the flexible screen assembly 100. The two ends of the support member 120 can also be on the same plane or approximately on the same plane. The curved portion 121 and the support portion 122 of the support member 120 can also be on or approximately on the same plane. The curved portion 121 and the support portion 122 of the support member 120 can be parallel to or approximately parallel to the axis L0. The entire support member 120 can support the flexible display screen 110.

[0028] like Figure 2As shown, the flexible screen assembly 100 can also be in a folded state. The two ends of the flexible display screen 110 can be located on opposite sides, and the two ends of the support member 120 can also be located on opposite sides. The curved region 111 of the flexible display screen 110 can be bent along the axis L0 to deform and form a curved shape, while the non-curved region 112 of the flexible display screen 110 can still be parallel or approximately parallel to the axis L0. The curved portion 121 of the support member 120 can be bent along the axis L0 to deform and form a curved portion 121, while the supporting portion 122 of the support member 120 can still be parallel or approximately parallel to the axis L0. The curved region 111 of the flexible display screen 110 can include an inner curved region 1111 and an outer curved region 1112 connected to each other. The outer curved region 1112 can be connected to the non-curved region 112, thereby allowing the flexible display screen 110 to form a teardrop-shaped curved shape. Similarly, the curved portion 121 of the support member 120 may include an inner curved portion 1211 and an outer curved portion 1212 connected to each other. The outer curved portion 1212 may be connected to the support portion 122, so that the inner curved portion 1211, the outer curved portion 1212, and the support portion 122 can make the support member 120 form a teardrop-shaped curved shape. The inner curved portion 1211 may be disposed relative to the inner curved region 1111 to support the inner curved region 1111, and the outer curved portion 1212 may be disposed relative to the outer curved region 1112 to support the outer curved region 1112.

[0029] It is understood that the outer curved region 1112 may include two, with the two outer curved regions 1112 located on opposite sides of the inner curved region 1111 and correspondingly connected to the two non-curved regions 112; similarly, the outer curved portion 1212 may include two, with the two outer curved portions 1212 located on opposite sides of the inner curved portion 1211 and correspondingly connected to the two support portions 122.

[0030] It is understood that the bending curvature direction of the inner bending region 1111 and the inner bending portion 1211 can be towards the axis L0; correspondingly, the bending curvature direction of the outer bending region 1112 and the outer bending portion 1212 can be away from the axis L0. The curvature direction of the inner bending region 1111 and the inner bending portion 1211 is opposite to the curvature direction of the outer bending region 1112 and the outer bending portion 1212.

[0031] It is understood that a transition region (e.g., but not limited to, a sloped transition region) may also be formed between the inner curved region 1111 and the outer curved region 1112; correspondingly, a transition region (e.g., but not limited to, a sloped transition region) may also be formed between the inner curved portion 1211 and the outer curved portion 1212. The support member 120 may, but is not limited to, have a backing adhesive or similar structure provided at this transition region to further assist the support member 120 in forming a teardrop-shaped curved shape. This application embodiment does not limit this aspect.

[0032] based on Figure 1 and Figure 2 For the structure of the flexible screen assembly 100 shown, please refer to... Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of a first structure of the support member 120 provided in an embodiment of this application. Figure 4 for Figure 3 The diagram shows a partially enlarged view of the support member 120. The support member 120 may have a plurality of through holes 123 provided in its curved portion 121.

[0033] Multiple through holes 123 can be spaced apart, and each through hole 123 can penetrate two opposite sides of the support member 120 along the thickness direction H4 to form a through hole structure. The thickness direction H4 can be perpendicular to the axis L0. The multiple through holes 123 can be arranged according to a preset rule, so that at least one rib 124 along a first direction H1 can be formed on the bent portion 121. The first direction H1 can be perpendicular to the axis L0 or perpendicular to the thickness direction H4 of the support member 120. For example, when the axis L0 is the Y-axis direction, the first direction H1 can be the X-axis direction, and the thickness direction H4 can be the Z-axis direction. The rib 124 along the first direction H1 on the bent portion 121 can be a transverse rib 124.

[0034] It is understandable that the through hole 123 can be a hollow structure, and the rib 124 can be a solid structure on the bent portion 121. The hole walls between adjacent through holes 123 can form the rib 124 on the bent portion 121. Among them, the rib 124 along the first direction H1, that is, the transverse rib 124, can provide stiffness. This stiffness can be the ability of the support member 120 to resist elastic deformation when subjected to force. The greater the stiffness, the stronger the ability of the support member 120 to resist elastic deformation, and the less likely the support member 120 is to deform; the smaller the stiffness, the weaker the ability of the support member 120 to resist elastic deformation, and the more likely the support member 120 is to deform but not easily return to its original shape. Therefore, in order for the bent portion 121 of the support member 120 to form a more suitable teardrop shape, the bent portion 121 needs to have suitable stiffness so that it can support the flexible display screen 110 in the folded state, while weakening its resistance to deformation and weakening the screen crease caused by the teardrop deformation when bent.

[0035] It is understood that the ratio of the length of the rib 124 along the first direction H1 to the length of the bent portion 121 along the first direction H1 can be greater than a preset ratio, which can be, but is not limited to, one-half. For example, the length of the rib 124 along the first direction H1 can be equal to or approximately equal to the length of the bent portion 121 along the first direction H1, so that the rib 124 in the first direction H1 can provide stiffness for the entire bent portion 121.

[0036] It is understood that, due to the different curvatures of the inner curved portion 1211 and the outer curved portion 1212, the required stiffness of the inner curved portion 1211 and the outer curved portion 1212 may differ, with the required stiffness of the outer curved portion 1212 often being greater than that of the inner curved portion 1211. Based on this, this application can provide multiple through holes 123 spaced apart within the outer curved portion 1212 (one or two outer curved portions 1212 of the support member 120), and arrange the multiple through holes 123 according to a preset configuration, so that the outer curved portion 1212 can form at least one rib 124 along the first direction H1. It should be noted that this application can also provide multiple through holes 123 spaced apart within the inner curved portion 1211, or simultaneously within the inner curved portion 1211 and the outer curved portion 1212. This application does not limit this aspect.

[0037] It is understood that the multiple through holes 123 may be arranged in the curved portion 121 according to, but not limited to, a pattern along the first direction H1, a pattern along the axis L0, a pattern along both the first direction H1 and the axis L0, or a pattern other than the first direction H1 and the axis L0. Of course, the multiple through holes 123 may also be arranged according to other patterns to form a rib along the first direction H1. This application does not limit this arrangement.

[0038] The support member 120 of this application embodiment has a plurality of through holes 123 spaced apart in the curved portion 121, and the plurality of through holes 123 are arranged according to a preset rule, so that the curved portion 121 can form at least one rib 124 along a first direction H1, which can be perpendicular to the axis L0. Based on this, in the embodiment of this application, the support member 120 has, on the one hand, multiple through holes 123 that can weaken the stiffness of the bent portion 121, allowing the support member 120 to form a teardrop-shaped bent shape; on the other hand, the ribs 124 along the first direction H1 can provide a certain stiffness to the bent portion 121 to support the flexible display screen 110. Thus, the through holes 123 and the ribs along the first direction H1 of this application can weaken the stiffness of the bent portion 121, so that the support member 120 can have a certain stiffness to support the flexible display screen 110 in the folded state, and can also avoid the screen from creases when the bent portion 121 is too stiff. The support member 120 of this application can form a better teardrop shape to support the flexible display screen 110 to form a better teardrop shape without creases.

[0039] Please refer to this again. Figure 3 and Figure 4 Multiple through holes 123 on the curved portion 121 (e.g., but not limited to the outer curved portion 1212) can be extended along the first direction H1, and the multiple through holes 123 can be spaced apart, so that a rib 124 along the first direction H1 can be formed between two adjacent through holes 123.

[0040] It is understood that the ratio of the length of the plurality of through holes 123 along the first direction H1 to the length of the curved portion 121 (e.g., but not limited to the outer curved portion 1212) along the first direction H1 can be greater than a preset ratio, so that the ratio of the length of the rib 124 along the first direction H1 to the length of the curved portion 121 (e.g., but not limited to the outer curved portion 1212) along the first direction H1 can be greater than the preset ratio. For example, but not limited to, the length of the plurality of through holes 123 along the first direction H1 can be equal to or approximately equal to the length of the curved portion 121 (e.g., but not limited to the outer curved portion 1212).

[0041] It is understood that multiple through holes 123 can be set at equal intervals, so that the width of the rib 124 formed between two adjacent through holes 123 (the width along the axis direction H0) can be equal, and ribs 124 with equal intervals and equal width can be formed on the curved portion 121 (e.g., but not limited to the outer curved portion 1212). The distribution of ribs 124 is more uniform, and the curved shape (teardrop shape) formed by the support member 120 is smoother and more rounded.

[0042] Among them, such as Figure 3 and Figure 4As shown, the plurality of through holes 123 may include two types of through-hole structures. For example, the plurality of through holes 123 may include at least one first through hole 101 and at least one second through hole 102, and each first through hole 101 and each second through hole 102 may extend along a first direction H1. The length of the first through hole 101 along the first direction H1 may be different from the length of the second through hole 102 along the first direction H1. For example, the length of the first through hole 101 along the first direction H1 may be less than the length of the second through hole 102 along the first direction H1. The first through holes 101 and the second through holes 102 may be arranged alternately, such that, except for the two through holes 123 at the ends, among the other through holes 123, one first through hole 101 may be located between two second through holes 102, and one second through hole 102 may be located between two first through holes 101.

[0043] It is understandable that the centers of the first through hole 101 and the second through hole 102 can be aligned, and the centers of the first through hole 101 and the second through hole 102 can be located on a straight line parallel to the axis L0. At this time, since the lengths of the first through hole 101 and the second through hole 102 along the first direction H1 are different, the ends of the first through hole 101 and the second through hole 102 may not be located on the same axis. The ends of the first through hole 101 and the second through hole 102 can have an alternating wavy shape. This alternating wavy shape allows the curved portion 121 to form a transition area, thereby reducing stress concentration. In particular, when multiple through holes 123 are provided in the outer curved portion 1212, this alternating wavy shape can disperse the stress in the transition area connecting the outer curved portion 1212 and the inner curved portion 1211, and can also disperse the stress in the transition area connecting the outer curved portion 1212 and the support portion 122, thereby further making the bending shape of the support member 120 smoother and more rounded.

[0044] It is understandable that the widths of the first through hole 101 and the second through hole 102 along the axis L0 can be equal, so that the first through hole 101 and the second through hole 102 can be through holes 123 of equal width, thereby reducing stress concentration.

[0045] It is understandable that the width of the first through hole 101 and the second through hole 102 along the axial direction H0 (the direction where the axial line L0 is located) can be slightly larger than the width of the rib 124 formed between them along the axial direction H0. Thus, the first through hole 101 and the second through hole 102 can further weaken the stiffness of the bent portion 121 (e.g., but not limited to the outer bent portion 1212).

[0046] It is understood that the first through hole 101 and the second through hole 102 can be arranged alternately at equal intervals so that the width of the rib 124 formed between the first through hole 101 and the second through hole 102 along the axial direction H0 can be equal, and the curved portion 121 (e.g., but not limited to the outer curved portion 1212) can have a plurality of ribs 124 of equal width.

[0047] The support member 120 of this application embodiment has a plurality of through holes 123 extending along the first direction H1 on the curved portion 121 (e.g., but not limited to the outer curved portion 1212), such as the first through hole 101 and the second through hole 102, which can form a rib 124 extending along the first direction H1 between the two through holes 123. The arrangement of the plurality of through holes 123 is simple and easier to manufacture.

[0048] Please refer to the following: Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of a second structure of the support member 120 provided in the embodiments of this application. Figure 6 for Figure 5 The diagram shows a partial enlarged view of the support member 120. The plurality of through holes 123 on the support member 120 of this application embodiment can also be arranged in two different ways.

[0049] The plurality of through holes 123 may include at least one set of first through hole structures 1231 and at least one set of second through hole structures 1232. The first through hole structures 1231 and the second through hole structures 1232 may be arranged alternately, for example, in an alternating arrangement of first through hole structure 1231, second through hole structure 1232, first through hole structure 1231, second through hole structure 1232, etc. The extending direction of the first through hole structure 1231 may differ from the extending direction of the second through hole structure 1232, and a rib 124 extending along a first direction H1 may be formed between adjacent sets of first through hole structures 1231 and sets of second through hole structures 1232.

[0050] It is understood that a set of first through-hole structures 1231 may include at least one through-hole, and a set of second through-hole structures 1232 may also include at least one through-hole. When the first through-hole structure 1231 or the second through-hole structure 1232 includes multiple through-holes, the multiple through-holes may be spaced apart. The number of through-holes included in a set of first through-hole structures 1231 may be the same as or different from the number of through-holes included in a set of second through-hole structures 1232, and this application embodiment does not limit this.

[0051] The support member 120 of this application embodiment is provided with alternating first through hole structures 1231 and second through hole structures 1232. Ribs 124 along the first direction H1 can be formed between the first through hole structures 1231 and the second through hole structures 1232 to provide a certain rigidity for the bent portion 121. Furthermore, the stress generated during bending can be dispersed by the two through hole structures with different extension directions, making the teardrop-shaped structure formed by the support member 120 smoother and more rounded.

[0052] Among them, such as Figure 5 and Figure 6 As shown, the first through-hole structure 1231 can extend along the first direction H1, and at least one through hole in the first through-hole structure 1231 can extend along the first direction H1. The first through-hole structure 1231 can be a horizontal hole structure. The second through-hole structure 1232 can extend along the axial direction H0, and at least one through hole in the second through-hole structure 1232 can extend along the axial direction H0. The second through-hole structure 1232 can be a vertical hole structure.

[0053] Understandably, when the first through-hole structure 1231 includes multiple through holes along the first direction H1, a transverse rib 124 can be generated between two adjacent through holes in the first through-hole structure 1231, which can provide stiffness; when the second through-hole structure 1232 includes multiple through holes along the axial direction H0, a longitudinal rib (rib parallel to the axial direction H0) can be generated between two adjacent through holes in the second through-hole structure 1232. The longitudinal rib provides virtually no stiffness (similar to a hinge), and the longitudinal second through-hole structure 1232 can weaken the overall stiffness of the support member 120.

[0054] It is understood that the first through-hole structure 1231 may include at least one first through-hole 101 and at least one second through-hole 102. The first through-hole 101 and the second through-hole 102 may extend along the first direction H1. The length of the first through-hole 101 along the first direction H1 may be different from the length of the second through-hole 102 along the first direction H1. The first through-hole 101 and the second through-hole 102 are arranged alternately. The center of the first through-hole 101 and the center of the second through-hole 102 may be aligned, so that the ends of the first through-hole 101 and the second through-hole 102 may not be located on the same axis. The ends of the first through-hole 101 and the second through-hole 102 may be in an alternating wavy shape, which can play a certain transition role and reduce stress concentration.

[0055] It is understood that the second through-hole structure 1232 may include a plurality of spaced third through-holes 103. The width of the third through-hole 103 along the first direction H1 may be smaller than the width of the first through-hole 101 and the second through-hole 102 along the axial direction H0, so that the width of the first through-hole 101 and the second through-hole 102 is greater than the width of the third through-hole 103. Therefore, the embodiments of this application can reduce the total number of transverse ribs 124 and increase the width of the transverse ribs 124 to provide rigidity.

[0056] It is understood that the number of first through holes 101, second through holes 102, and the sum of the number of first through holes 101 and through holes 123 can all be less than the number of third through holes 103. For example, the first through hole structure 1231 may include two first through holes 101 and one second through hole 102, and the second through hole structure 1232 may include sixteen third through holes 103.

[0057] The support member 120 in this embodiment of the application is provided with alternating horizontal and vertical through-hole structures 1231 and 1232, allowing the support member 120 to form horizontal ribs 124 and vertical ribs. The horizontal ribs 124 provide rigidity to support the flexible display screen 110; the vertical ribs provide virtually no rigidity, thus weakening the rigidity of the support member 120. Therefore, the support member 120 in this embodiment of the application, employing an arrangement of horizontal and vertical holes, can further weaken the rigidity of the support member 120. Especially for support members 120 that are too long or too thick, whose overall rigidity is very high, only using such a... Figure 3 and Figure 4 The transverse hole scheme shown, on the one hand, is limited by the dimensions of the rib 124 width and the hole width. For support members 120 that are too long or too thick, using only the transverse hole scheme cannot weaken the stiffness of the support member 120 to the required stiffness. Figure 5 and Figure 6 After the horizontal and vertical hole scheme shown, the stiffness is further weakened by the vertical hole, so that the support member 120, which is too long or too thick, can also have a suitable stiffness.

[0058] Please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of a third structure of the support member 120 provided in the embodiments of this application. Figure 8 for Figure 7 The diagram shows a partial enlarged view of the support member 120. The first through-hole structure 1231 and the second through-hole structure 1232 can also be oblique hole structures.

[0059] The first through-hole structure 1231 can extend along a second direction H2, the angle between the second direction H2 and the first direction H1 can be greater than zero degrees and less than ninety degrees, and the first through-hole structure 1231 can be inclined relative to the first direction H1. The second through-hole structure 1232 can extend along a third direction H3, the third direction H3 can be perpendicular to the second direction H2, so that the second through-hole structure 1232 can also be inclined relative to the first direction H1. For example, the angle between the first through-hole structure 1231 and the first direction H1 can be +45 degrees, and the angle between the second through-hole structure 1232 and the first direction H1 can be -45 degrees.

[0060] It is understood that the first through-hole structure 1231 may include at least one fifth through-hole 105 extending along the second direction, and the plurality of fifth through-holes 105 may be spaced apart, for example, but not limited to being equally spaced. The second through-hole structure 1232 may include at least one sixth through-hole 106 extending along a third direction, and the plurality of sixth through-holes 106 may be spaced apart, for example, but not limited to being equally spaced. The number of fifth through-holes 105 included in the first through-hole structure 1231 may be equal to or not equal to the number of sixth through-holes 106 included in the second through-hole structure 1232; this embodiment of the application does not limit this.

[0061] It is understood that the two ends of the multiple through holes in the first through hole structure 1231 can be aligned and located on a straight line extending along the first direction H1, and the two ends of the multiple through holes in the second through hole structure 1232 can also be located on a straight line aligned and extending along the first direction H1, so that a rib 124 along the first direction H1 can be formed between the first through hole structure 1231 and its adjacent second through hole structure 1232.

[0062] The support member 120 of this application embodiment includes an inclined first through hole structure 1231 and a second through hole structure 1232. The first through hole structure 1231 and the second through hole structure 1232 can have components of both horizontal ribs 124 and vertical ribs. Thus, this solution can also weaken the rigidity of the support member 120 that is too long or too thick.

[0063] Please refer to the following: Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of a fourth structure of the support member 120 provided in an embodiment of this application. Figure 10 for Figure 9 The diagram shows a partial enlarged view of the support member 120. The plurality of through holes 123 may include at least two sets of third through hole structures 1233 spaced apart, each set of third through hole structures 1233 extending in the same direction, and a rib 124 along the first direction H1 may be formed between adjacent sets of third through hole structures 1233.

[0064] It is understood that the third through-hole structure 1233 may include at least one through-hole, the extension direction of which may be the same as the overall extension direction of the third through-hole structure 1233. Multiple through-holes may be spaced apart, for example, but not limited to being equally spaced.

[0065] Understandably, the ends of the multiple through holes within the third through hole structure 1233 can be aligned and located on a straight line extending along the first direction H1, so that the ends of the multiple through holes are aligned. At this time, it is easier to form ribs 124 along the first direction H1 between two adjacent sets of third through hole structures 1233.

[0066] like Figure 9 and Figure 10 As shown, each group of third through-hole structures 1233 includes a plurality of fourth through-holes 104 extending along the axial direction H0. The ends of the plurality of fourth through-holes 104 are aligned about a straight line along the first direction H1. Each group of third through-hole structures 1233 can form a vertical hole structure. It can be understood that the length of the fourth through-hole 104 along the axial direction H0 can be greater than the length of the rib 124 formed between the two groups of third through-hole structures 1233 along the axial direction H0, so that the third through-hole structure 1233 can further weaken the rigidity of the support member 120.

[0067] It should be noted that the extension direction of the third through-hole structure 1233 is not limited to... Figure 9 and Figure 10 The direction H0 shown can be along the axis, for example, but not limited to, the first direction H1, or a direction forming an angle of 0 to 90 degrees with the first direction H1. This application does not limit the specific extension direction of the third through-hole structure 1233.

[0068] The support member 120 of this application embodiment includes at least two sets of third through-hole structures 1233 spaced apart. The support member 120 can either form ribs 124 along the first direction H1 between the two sets of third through-hole structures 1233, or use the third through-hole structures 1233 to weaken the rigidity of the support member 120. At the same time, since the third through-hole structures 1233 have a fixed extension direction, it is easier to manufacture the third through-hole structures 1233 during the manufacturing process of the support member 120.

[0069] It should be noted that the above is merely an exemplary description of providing multiple through holes 123 on the support member 120 of this application to form ribs 124 along the first direction H1. The multiple through holes 123 can also be arranged according to other preset rules. This application does not limit the specific arrangement of the multiple through holes 123.

[0070] In this embodiment, the support member 120 can be a metal plate, such as a SUS series metal plate (Japanese Material Standard metal plate), titanium alloy, etc. A steel support member 120 can have a relatively thin thickness, making it less likely to increase the thickness of the flexible screen assembly 100. Alternatively, the support member 120 can be a carbon fiber plate with a density of 1.81 g / cm³, resulting in a lighter weight. It should be noted that this embodiment does not limit the specific material of the support member 120.

[0071] In this embodiment, the support member 120 arranges multiple through holes 123 according to the aforementioned preset rules, which ensures that the rigidity of the support member 120 meets the requirements. For a support member 120 of a certain material, thickness, and length, the number of ribs 124 and the interface moment of inertia of ribs 124 can be controlled by adjusting the rib width and hole width. Combined with the lateral modulus of the support member 120, the required overall rigidity of the support member 120 can be obtained, ultimately achieving a better teardrop shape effect and reducing the screen crease effect.

[0072] For example, the width of the rib 124 and the width of the hole can be adjusted according to the following formula:

[0073] K = E·I

[0074] Where K is the stiffness of support 120; E is the material modulus of support 120; and I is the moment of inertia of support 120. I can be calculated using the following formula:

[0075] I = (b·h) 3 ) / 12

[0076] Where b is the cross-sectional width of the rib 124 of the support member 120; h is the thickness of the rib 124 of the support member 120 (the dimension along the thickness direction H4 of the support member 120).

[0077] According to the two formulas above, with a fixed thickness h, the moment of inertia of the support member 120 can be adjusted by adjusting the cross-sectional width b of the ribs 124 (which is the total cross-sectional width of all ribs 124 extending along the first direction H1 on the support member 120), thereby ultimately adjusting the stiffness of the support member 120. Conversely, once the suitable stiffness of the support member 120 is known, the cross-sectional width b of the ribs 124 can be calculated, and the cross-sectional width of the ribs 124 can be made to meet the requirements by appropriately arranging the through holes 123 of the support member 120.

[0078] It should be noted that the above is merely an exemplary description of designing the arrangement of through holes 123 based on the cross-sectional width of the rib 124. Other methods can also be used to design the arrangement of through holes 123 in this application embodiment, such as, but not limited to, designing the arrangement of through holes 123 through simulation. This application embodiment does not limit this approach.

[0079] In the embodiment of this application, the support member 120 has a plurality of spaced through holes 123 in the curved portion 121 of the support member 120, for example, outwardly curved, to form ribs 124 along the direction H0 perpendicular to the axis. This can provide a certain rigidity to the support member 120, or weaken the rigidity of the support member 120, so that the support member 120 can form a better teardrop curved shape. Meanwhile, the multiple through holes 123 in this application can provide a transition zone for the support member 120, which can avoid stress concentration and reduce stress abrupt changes, and further improve the smoothness of the teardrop-shaped bending form of the support member 120. In addition, the through holes 123 in this application are arranged alternately in different extension directions, which can also weaken the stiffness of the support member 120 that is longer and thicker. This allows the method of this application to be adapted to support members 120 of different sizes, and is not limited by screen size. It can also design the through holes 123 of the outer bending part 1212 more quickly. At the same time, the arrangement of the through holes 123 is designed by the formula of this application. The calculation method is simple and the stiffness calculation is more accurate, which can save simulation resources and shorten the project cycle.

[0080] It should be noted that the above is only an exemplary description of the support member 120 in this application embodiment. The support member 120 in this application embodiment can also be other structures, such as, but not limited to, providing a through hole 123 along the axis L0 in the inner curved portion 1211. This application embodiment does not limit the specific structure of the support member 120.

[0081] It should be noted that the above is merely an exemplary description of the flexible screen assembly 100 in this application embodiment. In addition to the support member 120 and the flexible display screen 110, the flexible screen assembly 100 in this application embodiment may also include, but is not limited to, structures such as a rotating shaft and a motor. This application embodiment does not limit the specific structure of the flexible screen assembly 100.

[0082] Based on the structure of the flexible screen component 100 and the support member 120 described above, this application also provides an electronic device 10. The electronic device 10 can be a smartphone, tablet computer, or other similar device, and can also be a gaming device, augmented reality (AR) device, automotive device, data storage device, audio playback device, video playback device, laptop computer, desktop computing device, etc. Please refer to... Figure 11 , Figure 11This is a schematic diagram of the structure of an electronic device 10 provided in an embodiment of this application. The electronic device 10 in this embodiment may include a flexible screen assembly 100.

[0083] like Figure 11 As shown, the electronic device 10 may also include a first body 200, a second body 300, a circuit board 400, and a power supply 500.

[0084] The first body 200 and the second body 300 provide support for the electronic components in the electronic device 10, allowing them to be mounted together. For example, the first body 200 and the second body 300 can support the flexible screen assembly 100. Furthermore, electronic components in the electronic device 10 such as the camera, receiver, circuit board 400, and power supply 500 can be mounted on the first body 200 and the second body 300 for fixation.

[0085] The first body 200 and the second body 300 may include a hollow frame structure, or a thin plate or sheet structure. For example, the first body 200 and the second body 300 may include a drawer-like or comb-like structure. It is understood that the first body 200 and the second body 300 may, but are not limited to, be provided with pull-out or sliding structures such as slide rails or tracks, so that the first body 200 and the second body 300 can slide, pull out, or perform other operations to achieve relative movement between the first body 200 and the second body 300. These pull-out or sliding structures can be found in the descriptions of related technologies and will not be detailed here.

[0086] The first body 200 and the second body 300 can move relative to each other in directions of approaching or moving away from each other. During their mutual movement, the first body 200 and the second body 300 can drive all or part of the flexible screen assembly 100 to move together (for example, when both the first body 200 and the second body 300 can move, all the flexible screen assemblies 100 can move with the mutual movement of the first body 200 and the second body 300; when one of the first body 200 and the second body 300 moves while the other body does not move, part of the flexible screen assembly 100 can remain stationary with the stationary body, while the other part of the flexible screen assembly 100 can move with the moving body). The flexible screen assembly 100 can expand or contract with the movement of the first body 200 and the second body 300, so that the flexible screen assembly 100 can switch between an expanded state and a folding state.

[0087] The circuit board 400 can be mounted on either the first body 200 or the second body 300, and can serve as the motherboard of the electronic device 10. The circuit board 400 may integrate a processor, and may also integrate one or more functional components such as a headphone jack, an accelerometer, a gyroscope, and a motor. The flexible display screen 110 can be electrically connected to the circuit board 400 for control via the processor on the circuit board 400.

[0088] The power supply 500 can be installed on either the first body 200 or the second body 300. Simultaneously, the power supply 500 can be electrically connected to the circuit board 400 to power the electronic device 10. The circuit board 400 can be equipped with a power supply 500 management circuit. This power supply 500 management circuit is used to distribute the voltage provided by the power supply 500 to the various electronic components within the electronic device 10.

[0089] It is understood that the above are merely exemplary examples of the electronic device 10. The electronic device 10 in this application embodiment may also include components such as a camera, a sensor, and a sound-to-electric conversion device. These components can be found in the descriptions in related technologies and will not be repeated here.

[0091] The support member, flexible screen assembly, and electronic device provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application, and the descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope.
