Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a foldable screen and a foldable electronic device. Background Technology

[0002] Foldable screens, with their bendable nature, allow electronic devices to be folded and switched between unfolded and folded states. Foldable electronic devices offer a larger display area and are easy to carry, making them increasingly popular with consumers.

[0003] During the long-term use of foldable electronic devices, the foldable screen will be repeatedly folded and unfolded. In existing foldable screens, uneven creases will appear in the bending area, which are particularly noticeable when the screen is off. This affects the appearance of the foldable screen and results in a poor user experience. Furthermore, it can easily lead to problems such as film layer breakage and delamination, reducing the lifespan of the foldable screen. Summary of the Invention

[0004] This application provides a foldable screen and a foldable electronic device. The foldable screen has high tensile strength, which can reduce the elongation deformation of the foldable screen, improve the creases of the foldable screen, enhance the appearance of the foldable screen, and extend the service life of the foldable screen.

[0005] One aspect of this application provides a foldable screen having a first region, a bendable region, and a second region sequentially disposed along a first direction. The foldable screen includes:

[0006] The display module has a first side and a second side on both sides in the thickness direction, with the first side corresponding to the display surface of the display module.

[0007] A reinforcing layer is disposed on at least one of the first side and the second side of the display module;

[0008] The reinforcement layer on at least one side includes a substrate and a plurality of flexible glass portions, each of which is embedded in the substrate; each of the flexible glass portions is spaced apart along a first direction, and each of the flexible glass portions extends along a second direction and penetrates both sides of the folding screen, the second direction being perpendicular to the first direction.

[0009] The foldable screen provided in this application includes a display module, with a first side and a second side on both sides of the display module's thickness direction. A reinforcing layer is provided on at least one of the first and second sides of the display module. The reinforcing layer includes a substrate and multiple flexible glass portions, each embedded in the substrate. The flexible glass portions are spaced apart along a first direction and extend along a second direction perpendicular to the first direction, penetrating both sides of the foldable screen. By spaced multiple flexible glass portions in the substrate, each flexible glass portion has a small width, high hardness, smaller deformation, and better tensile strength, which reduces the tensile deformation of the foldable screen, effectively improves creases, enhances the appearance of the foldable screen, and improves the user experience of foldable electronic devices. Furthermore, by embedding each flexible glass portion in the substrate, the substrate can better absorb deformation stress, enhancing the integrity and consistency of the reinforcing layer and extending the lifespan of the foldable screen.

[0010] In one possible implementation, the reinforcing layer includes a first reinforcing layer and a second reinforcing layer, wherein the first reinforcing layer is located on a first side of the display module and the second reinforcing layer is located on a second side of the display module.

[0011] By setting reinforcing layers on both sides of the display module, the first and second reinforcing layers constrain the display module, thereby enhancing the stability of the display module and improving the overall tensile strength of the foldable screen.

[0012] In one possible implementation, the first reinforcing layer and the second reinforcing layer are respectively attached to the two sides of the display module.

[0013] By directly attaching the first and second reinforcing layers to the two sides of the display module, the first and second reinforcing layers exert a stronger binding effect on the display module, which can enhance the stability of the display module, improve the stability of the foldable screen, and reduce or even eliminate the creases of the foldable screen.

[0014] In one possible implementation, at least a portion of the flexible glass portion is located on the first surface of the reinforcing layer; wherein the first surface is the side of the reinforcing layer facing the front of the folding screen.

[0015] By placing at least a portion of the flexible glass portion on the first surface of the reinforcing layer, when the foldable screen is bent, the flexible glass portions in the reinforcing layer are closer together, allowing the flexible glass portions to better exert their tensile resistance, which helps to improve the tensile resistance of the reinforcing layer and makes the foldable screen more resistant to tensile deformation.

[0016] In one possible implementation, each flexible glass portion is disposed on the first surface of the reinforcing layer.

[0017] By placing each flexible glass component on the first surface of the reinforcing layer, each flexible glass component can effectively exert its tensile strength, resulting in good overall tensile strength for the foldable screen. Furthermore, this facilitates the connection of each flexible glass component to the substrate, improving the manufacturing efficiency of the reinforcing layer.

[0018] In one possible implementation, the flexible glass portion located in the bendable area is away from the front of the foldable screen, while the flexible glass portions located in the first area and the flexible glass portions located in the second area are close to the front of the foldable screen.

[0019] By moving the flexible glass portion of the bendable area away from the front of the foldable screen and moving the flexible glass portions of the first and second areas closer to the front of the foldable screen, when the foldable screen is bent, the overall bending degree of all the flexible glass portions in the reinforcing layer is greater than the overall bending degree of the foldable screen. This results in a stronger tensile resistance of the reinforcing layer and a better resistance of the foldable screen to tensile deformation.

[0020] In one possible implementation, the flexible glass portion located in the bendable area is disposed on the second surface of the reinforcing layer; wherein the second surface is the side surface of the reinforcing layer facing away from the front of the foldable screen.

[0021] By placing the flexible glass portion of the bendable area on the second surface of the reinforcing layer, the step difference between the flexible glass portion of the bendable area and the flexible glass portions of the first and second areas is greater. When the foldable screen is bent, the overall bending degree of all the flexible glass portions in the reinforcing layer is greater, the tensile strength of the reinforcing layer is better, and the creases of the foldable screen can be reduced or even eliminated better.

[0022] In one possible implementation, the flexible glass portion gradually approaches the front of the foldable screen from the bendable area to the first area and from the bendable area to the second area.

[0023] In the direction from the bendable area to the first area and in the direction from the bendable area to the second area, by gradually bringing the flexible glass parts closer to the front of the folding screen, the flexible glass parts are arranged in a regular manner. The tensile resistance of the reinforcing layer on the folding screen as a whole is more balanced, and the uniformity and consistency of the folding screen's overall resistance to tensile deformation are better, which helps to improve the flatness of the folding screen.

[0024] In one possible implementation, the spacing between any two adjacent flexible glass sections is equal.

[0025] By ensuring equal spacing between every two adjacent flexible glass sections, the flexible glass sections are evenly spaced within the reinforcing layer. This results in more uniform tensile strength across different areas of the reinforcing layer, leading to a more balanced overall tensile strength for the foldable screen and improving its flatness.

[0026] In one possible implementation, the widths of each flexible glass portion are equal.

[0027] By ensuring that the widths of each flexible glass component are equal, the tensile strength of each component is more uniform, resulting in a more balanced and consistent tensile strength across the entire reinforcing layer. Furthermore, this facilitates the fabrication of each flexible glass component, thereby improving the production efficiency of the reinforcing layer.

[0028] In one possible implementation, the width of the flexible glass portion located in the bendable region is greater than the width of the flexible glass portion located in the first region and the width of the flexible glass portion located in the second region.

[0029] By increasing the width of the flexible glass portion in the bendable area, the tensile strength of the reinforcing layer in the bendable area can be enhanced, improving the flatness of the bendable area and its surrounding region. Furthermore, by maintaining a smaller width for the flexible glass portions in the first and second zones, the tensile deformation of the first and second zones can be reduced, minimizing their impact on the bendable area. This, in turn, improves the flatness of the foldable screen and reduces or even eliminates creases.

[0030] In one possible implementation, the ratio of the thickness of the flexible glass portion to the total thickness of the reinforcing layer is ≥1 / 2.

[0031] By ensuring that the thickness of the flexible glass portion is greater than or equal to half the total thickness of the reinforcing layer, the reinforcing layer occupies a larger thickness space in the flexible glass portion. This ensures that the flexible glass portion can effectively perform its tensile resistance function, guarantees that the reinforcing layer has a good tensile resistance effect, improves the flatness of the foldable screen, and improves or even eliminates the creases of the foldable screen.

[0032] In one possible implementation, the first reinforcing layer includes a first substrate and a plurality of first flexible glass portions embedded in the first substrate, and the second reinforcing layer includes a second substrate and a plurality of second flexible glass portions embedded in the second substrate.

[0033] In one possible implementation, the width of each first flexible glass portion is a first width, and the spacing between any two adjacent first flexible glass portions is a first spacing.

[0034] By ensuring that the width of each first flexible glass section is equal and the spacing between any two adjacent first flexible glass sections is equal, the first reinforcing layer exhibits good balance and consistency. This is beneficial for improving the overall tensile strength of the foldable screen, enhancing its flatness, and reducing or even eliminating creases. Furthermore, it facilitates the design and fabrication of the first substrate, improving the production efficiency of the first reinforcing layer.

[0035] In one possible implementation, the width of each second flexible glass portion is the second width, and the spacing between any two adjacent second flexible glass portions is the second spacing.

[0036] By ensuring that the width of each second flexible glass section is equal and the spacing between each two adjacent second flexible glass sections is equal, the overall tensile strength of the second reinforcing layer is more balanced, which is beneficial to improving the overall tensile strength of the foldable screen, improving the flatness of the foldable screen, and facilitating the design and processing of the second reinforcing layer.

[0037] In one possible implementation, the first width is equal to the second width, and the first spacing is equal to the second spacing.

[0038] By making the second width equal to the first width and the second spacing equal to the first spacing, the tensile properties of the second reinforcing layer and the first reinforcing layer are similar. The stability of the display module can be enhanced by the restraint of the first reinforcing layer and the second reinforcing layer on the display module.

[0039] In one possible implementation, the orthographic projection of each first flexible glass portion onto the second reinforcing layer completely overlaps with that of each second flexible glass portion.

[0040] By aligning each second flexible glass portion in the second reinforcing layer with each first flexible glass portion in the first reinforcing layer, the structure of the second reinforcing layer can be completely identical to that of the first reinforcing layer. Good consistency between the first and second reinforcing layers improves the stability and reliability of the foldable screen. Furthermore, it facilitates the processing and manufacturing of both the first and second reinforcing layers.

[0041] In one possible implementation, the first width is greater than the second width, and the first spacing is less than or equal to the second spacing.

[0042] By making the first width greater than the second width, the tensile strength of the first reinforcing layer can be enhanced, improving the overall tensile strength of the foldable screen, increasing its flatness, and reducing or even eliminating creases. Furthermore, by making the first spacing smaller than the second spacing, excessive performance differences between different areas of the first reinforcing layer can be avoided, improving the overall balance and consistency of the first reinforcing layer.

[0043] In one possible implementation, the width of the second flexible glass portion located in the bendable region is greater than the width of the second flexible glass portion located in the first region and the width of the second flexible glass portion located in the second region.

[0044] By making the width of the second flexible glass portion in the bendable area greater than the width of the second flexible glass portions in the first and second areas, the tensile strength of the second reinforcing layer in the bendable area can be enhanced. Through the combined effect of the first and second reinforcing layers, the tensile strength of the bendable area of ​​the foldable screen is enhanced, improving the flatness of the bendable area and its surrounding region.

[0045] In one possible implementation, the width of the second flexible glass portion located in the bendable region is greater than the first width, and the widths of the second flexible glass portions located in the first region and the second flexible glass portions located in the second region are less than the first width.

[0046] In one possible implementation, the spacing between any two adjacent second flexible glass portions is equal, and the spacing between adjacent second flexible glass portions is greater than the first spacing.

[0047] In one possible implementation, each of the first flexible glass portions is disposed on the first surface of the first reinforcing layer.

[0048] By placing each of the first flexible glass components on the first surface of the first reinforcing layer, the first surface of the first reinforcing layer has strong tensile strength, which can improve the flatness of the foldable screen. Furthermore, it facilitates the connection of each of the first flexible glass components to the substrate, thereby improving the manufacturing efficiency of the first reinforcing layer.

[0049] In one possible implementation, the first reinforcing layer includes a first substrate and a flexible glass layer disposed on the first substrate, and the second reinforcing layer includes a second substrate and a plurality of second flexible glass portions embedded in the second substrate.

[0050] By setting a first substrate and a flexible glass layer to form a first reinforcing layer, the flexible glass layer covers the entire first substrate. The large coverage area of ​​the flexible glass layer provides good tensile strength, thus improving the tensile performance of the first reinforcing layer. Furthermore, the combined effect of the first and second reinforcing layers enhances the overall tensile strength of the foldable screen, improves its flatness, and reduces or even eliminates creases.

[0051] In one possible implementation, it also includes:

[0052] The protective layer is located on the front of the foldable screen.

[0053] In one possible implementation, it also includes:

[0054] A support plate is located on the back of the foldable screen; the support plate includes a deformable part and a non-deformable part, with the non-deformable part connected to both sides of the deformable part.

[0055] Another aspect of this application provides a foldable electronic device, including a housing assembly and a foldable screen as described above, the foldable screen being mounted on the housing assembly.

[0056] The foldable electronic device provided in this application includes a foldable screen, which includes a display module. The display module has a first side and a second side on its two sides along its thickness direction. A reinforcing layer is provided on at least one of the first and second sides of the display module. The reinforcing layer includes a substrate and multiple flexible glass portions, each embedded in the substrate. These flexible glass portions are spaced apart along a first direction and extend along a second direction perpendicular to the first direction, penetrating both sides of the foldable screen. By spaced multiple flexible glass portions in the substrate, each flexible glass portion has a small width, high hardness, smaller deformation, and better tensile strength, reducing the tensile deformation of the foldable screen, effectively improving creases, enhancing the appearance of the foldable screen, and improving the user experience of the foldable electronic device. Furthermore, by embedding each flexible glass portion in the substrate, the substrate can better absorb deformation stress, enhancing the integrity and consistency of the reinforcing layer and extending the lifespan of the foldable screen.

[0085] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0086] This application provides a foldable electronic device, which includes, but is not limited to, foldable electronic products such as mobile phones, tablet personal computers, laptop computers, notebook computers, netbooks, personal digital assistants (PDAs), personal computers, multimedia players, e-book readers, in-vehicle devices, virtual reality (VR) devices, augmented reality (AR) devices, or wearable devices. Wearable devices include, but are not limited to, smart bracelets, smartwatches, smart head-mounted displays, and smart glasses.

[0087] Figure 1 This is a schematic diagram of the structure of the foldable electronic device provided in the embodiment of this application when it is in the unfolded state. Figure 2 for Figure 1 The diagram shows the structure of the foldable electronic device in its folded state. Figure 3 for Figure 1 A schematic diagram of the structure of the foldable electronic device in a semi-expanded state.

[0088] Reference Figures 1 to 3 As shown, this embodiment uses a foldable mobile phone as an example of a foldable electronic device 10 for explanation.

[0089] For the foldable electronic device 10, it can have different usage states in different usage scenarios. Figure 1 The foldable electronic device 10 is shown in its unfolded state. The unfolding angle α of the foldable electronic device 10 is, for example, 180°. At this time, the foldable electronic device 10 can realize a large screen display. Figure 2The foldable electronic device 10 is shown in a folded state, in which the foldable electronic device 10 is small in size and easy to carry; Figure 3 The diagram shows a foldable electronic device 10 in a semi-expanded state, where the foldable electronic device 10 is hovering at an angle between the unfolded and folded states. For example, the hovering angle β of the foldable electronic device 10 can be 120°, 130°, 140°, or 150°, etc.

[0090] It should be noted that the angles illustrated in this embodiment are allowed to have slight deviations. For example, Figure 1 The unfolding angle α of the foldable electronic device 10 shown is 180°, meaning that the unfolding angle α can be 180°, or approximately 180°, such as 170°, 175°, 185°, or 190°. The angles illustrated in the following text can be understood in the same way.

[0091] in addition, Figures 1 to 3 The foldable electronic device 10 shown is a foldable electronic device 10 capable of folding once. The foldable electronic device 10 includes two parts that can rotate relative to each other. When the two parts rotate to be coplanar, the foldable electronic device 10 is in an unfolded state (e.g., Figure 1 As shown), when the two parts are rotated to overlap, the foldable electronic device 10 is in a folded state (as shown). Figure 2 As shown), when the two parts are rotated to a certain angle between the unfolded and folded states, the foldable electronic device 10 is in a semi-unfolded state (as shown). Figure 3 (As shown).

[0092] In other embodiments, the foldable electronic device 10 may also be an electronic device capable of folding more than twice. In this case, the foldable electronic device 10 may include multiple parts that are rotatably connected in sequence. Two adjacent parts may be relatively far apart to be unfolded into an unfolded state, and two adjacent parts may also be relatively close to be folded into a folded state.

[0093] Figure 4 This is an exploded structural diagram of a foldable electronic device provided in an embodiment of this application. (Refer to...) Figure 4 As shown, the foldable electronic device 10 includes a display screen 100 and a housing assembly 200. One side surface of the display screen 100 is used to display image information; this side surface is typically defined as its front surface, and the opposite side surface is its back surface. The housing assembly 200 surrounds the periphery and back surface of the display screen 100, providing support, fixation, and protection for the display screen 100. The front surface of the display screen 100 is exposed outside the housing assembly 200 for users to view the content displayed on the display screen 100 or to perform input operations on the foldable electronic device 10.

[0094] The display screen 100 of the foldable electronic device 10 may include a foldable screen 100a. The foldable screen 100a may include a first region 101, a bendable region 102, and a second region 103 arranged sequentially along a first direction. In other words, in the first direction, the bendable region 102 is located between the first region 101 and the second region 103. The folding method of the foldable electronic device 10 can be... Figures 1 to 3 The horizontal fold shown in the diagram allows the first direction to be... Figure 1 The X direction is shown in the figure. Of course, the foldable electronic device 10 can also be folded vertically, and this embodiment does not limit this.

[0095] For example, in the foldable screen 100a, at least the bendable area 102 is made of a flexible material so that the bendable area 102 can be bent. The first area 101 and the second area 103 can be made of flexible materials, or they can be made of rigid materials, or they can be made of partially rigid materials and partially flexible materials. This embodiment does not limit this.

[0096] The foldable screen 100a can be, but is not limited to, an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MLED) display, a micro organic light-emitting diode (MOLED) display, or a quantum dot light-emitting diode (QLED) display, etc.

[0097] During use, the first area 101 and the second area 103 of the foldable screen 100a always remain in a flat state, while the bendable area 102 of the foldable screen 100a can be bent to change the angle between the first area 101 and the second area 103, so that the foldable screen 100a can be folded or unfolded with the movement of the housing assembly 200, thereby realizing the switching of the foldable electronic device 10 between the folded state and the unfolded state.

[0098] Driven by the housing assembly 200, the foldable screen 100a can switch between an unfolded state and a folded state. Figure 1 and Figure 4As shown, when the foldable screen 100a is in the unfolded state, the first area 101 and the second area 103 are in an unfolded state with their positions relatively far apart, while the bendable area 102 is in a flattened state without bending. The first area 101, the second area 103, and the bendable area 102 all face the same direction and are coplanar. At this time, the angle between the first area 101 and the second area 103 is 180°. The foldable screen 100a can achieve a large-screen display, providing users with richer information and a better user experience. Combined with... Figure 2 and Figure 4 As shown, when the foldable screen 100a is in the folded state, the first area 101 and the second area 103 are stacked relative to each other, and the bendable area 102 is in a bent state. The bending angle of the bendable area 102 is, for example, 180°. At this time, the foldable electronic device 10 is small in size, making it easy to carry and store.

[0099] It should be noted that this embodiment takes the foldable electronic device 10 as an inward-folding electronic device as an example. When the foldable electronic device 10 is in the folded state, the first area 101 and the second area 103 of the foldable screen 100a are relatively close together, the bendable area 102 is in a bent state, and the housing assembly 200 protects the foldable screen 100a from being scratched by hard objects. (Refer to...) Figure 2 or Figure 3 As shown, if the inward-folding electronic device needs to realize the display function in the folded state, a flat screen 100b can be added to the back of the housing. The foldable electronic device 10 realizes the display function by relying on the flat screen 100b in the folded state.

[0100] In other words, the inward-folding electronic device may include a foldable screen 100a and a flat screen 100b. The foldable screen 100a can be attached to the front of the housing assembly 200. As the housing assembly 200 moves, the foldable screen 100a can switch between an unfolded state and a folded state. When the foldable electronic device 10 is in the folded state, the foldable screen 100a is not visible. The flat screen 100b can be attached to the back of the housing assembly 200. The flat screen 100b displays information when the foldable electronic device 10 is in the folded state.

[0101] In other examples, the foldable electronic device 10 can also be an outward-folding electronic device. When the foldable electronic device 10 is in the folded state, the first area 101 and the second area 103 of the foldable screen 100a are opposite to each other, and the housing assembly 200 is located between the first area 101 and the second area 103. The foldable screen 100a is surrounded by the housing assembly 200 and is visible to the user. When the outward-folding electronic device is in the folded state, the foldable screen 100a is exposed, and the display function can be realized using the foldable screen 100a. Therefore, it is not necessary to add a flat screen 100b to the back of the housing in order to realize the display function of the foldable electronic device 10 in the folded state.

[0102] In some embodiments, the foldable electronic device 10, especially the inward-folding electronic device, can be suspended at an angle between the unfolded and folded states. For example, the suspension angle of the foldable electronic device 10 can be 120°, 130°, 140°, or 150°. The housing assembly 200 can be suspended in a semi-unfolded state between the folded and unfolded states by the damping force provided by the housing assembly 200, and the foldable screen 100a remains in the semi-unfolded state along with the housing assembly 200. At this time, the bendable area 102 of the foldable screen 100a is also in a bent state, and the degree of bending of the bendable area 102 is less than the degree of bending when in the folded state. The first area 101 and the second area 103 of the foldable screen 100a are relatively tilted, and the included angle between the first area 101 and the second area 103 is, for example, 120°, 130°, 140°, or 150°.

[0103] The housing assembly 200 supports and secures the folding screen 100a, and drives the folding screen 100a to switch between a folded state and an unfolded state. (See reference...) Figure 4 As shown, the housing assembly 200 includes a first housing 210, a second housing 220 and a rotating shaft 230. The rotating shaft 230 connects the first housing 210 and the second housing 220. The first housing 210 and the second housing 220 are rotatably connected by the rotating shaft 230, thereby realizing relative rotation between the first housing 210 and the second housing 220.

[0104] The first housing 210 supports and fixes the first area 101 of the foldable screen 100a, and the second housing 220 supports and fixes the second area 103 of the foldable screen 100a. In other words, the first area 101 of the foldable screen 100a is fixedly connected to the first housing 210, and the second area 103 of the foldable screen 100a is fixedly connected to the second housing 220. The bendable area 102 of the foldable screen 100a is set corresponding to the pivot 230. When the pivot 230 drives the first housing 210 and the second housing 220 to rotate relative to each other, the first area 101 and the second area 103 of the foldable screen 100a change their orientation accordingly, and the bendable area 102 of the foldable screen 100a bends or flattens as the orientation of the first area 101 and the second area 103 changes.

[0105] The pivot 230 drives the first housing 210 and the second housing 220 to rotate relative to each other, allowing the foldable electronic device 10 to switch between a folded state and an unfolded state. Specifically, the first housing 210 and the second housing 220 can rotate in a direction away from each other until they are coplanar. At this point, the housing assembly 200 is in the unfolded state, and the foldable screen 100a is also in the unfolded state along with the housing assembly 200. Figure 1As shown; the first housing 210 and the second housing 220 can also rotate towards each other until they are stacked relative to each other. At this time, the housing assembly 200 is in a folded state, and the folding screen 100a is in a folded state along with the folding of the housing assembly 200, as shown. Figure 2 As shown.

[0106] For example, the first housing 210 may have a support surface facing a first region 101 of the foldable screen 100a, and the first region 101 of the foldable screen 100a is attached to the support surface of the first housing 210, for example, the first region 101 of the foldable screen 100a is bonded to the support surface of the first housing 210. Similarly, the second housing 220 may have a support surface facing a second region 103 of the foldable screen 100a, and the second region 103 of the foldable screen 100a is attached to the support surface of the second housing 220, for example, the second region 103 of the foldable screen 100a is bonded to the support surface of the second housing 220.

[0107] Additionally, both the first housing 210 and the second housing 220 can have a receiving space for installing some functional components (not shown in the figure) of the foldable electronic device 10. For example, the receiving space can be used to install circuit boards, batteries, camera modules, microphones, speakers, and other components. For example, circuit boards can be provided in both the first housing 210 and the second housing 220, and electrical connections between the components in the two housings can be achieved through the circuit boards in the two housings. The battery used to power the components can be provided only in the first housing 210 or the second housing 220, or the battery can be provided in both the first housing 210 and the second housing 220. As for other components such as camera modules, microphones, and speakers, they can be centrally located in the first housing 210 or the second housing 220, or some components can be located in the first housing 210 and some components can be located in the second housing 220.

[0108] Continue to refer to Figure 4 In the housing assembly 200 of the foldable electronic device, both the first housing 210 and the second housing 220 may include a mid-frame 201, and the first area 101 and the second area 103 of the foldable screen 100a may be supported on the front of the corresponding mid-frame 201. Specifically, for outward-folding electronic devices or inward-folding electronic devices without an additional flat screen 100b, both the first housing 210 and the second housing 220 of the electronic device 1 may also include a back cover 202, which is connected to the side surface of the mid-frame 201 facing away from the foldable screen 100a. For inward-folding electronic devices with an additional flat screen 100b, one of the first housing 210 and the second housing 220 may not include the back cover 202, and instead, the flat screen 100b may be mounted on the back of the mid-frame 201 as an alternative.

[0109] In the first housing 210 and the second housing 220, the middle frame 201 and the back cover 202 (or the straight screen 100b) together form a receiving cavity, which is used to install the aforementioned circuit board, battery, camera module, microphone, speaker and other devices.

[0110] Figure 5 This is a schematic diagram of the structure of a foldable screen in related technologies. Figure 6 for Figure 5 The exploded structure diagram of the foldable screen in the image. (Refer to...) Figure 5 or Figure 6 As shown, in related technologies, a foldable screen 300 generally includes a display module 310, a cover plate 320, a support plate 330, and an adhesive layer 340. The display module 310 is used to display image information. The cover plate 320 is located on the front of the foldable screen 300, covering the display module 310, and is used to protect the underlying structural layers (including the display module 310). The support plate 330 is located on the back of the foldable screen 300, and is used to support the structural layers located thereon. The adhesive layer 340 is located between the display module 310 and the support plate 330, and the adhesive layer 340 is, for example, adhesive foam, to achieve the connection between the display module 310 and the support plate 330.

[0111] The support plate 330 can be a metal plate, for example, a steel plate. The portion of the support plate 330 corresponding to the bendable area of ​​the foldable screen 300 can be a hollow structure, while the portions of the support plate 330 corresponding to the first and second areas of the foldable screen 300 can be solid structures. This allows the support plate 330 to function as a support while also allowing the portion corresponding to the bendable area to be bent and deform, thus enabling the foldable screen 300 to switch between an unfolded and folded state. For example, the portion of the support plate 330 corresponding to the bendable area may include multiple connecting strips 331 arranged sequentially. Adjacent connecting strips 331 are connected by an elastic structure, and each connecting strip 331 can move as the foldable screen 300 unfolds or folds.

[0112] Among them, reference Figure 5 or Figure 6 As shown, the display module 310 may include a display encapsulation layer 311 and a substrate layer 312. The display encapsulation layer 311 is the core functional layer of the display module 310, used to realize the function of displaying image information. The substrate layer 312 is used to support the display encapsulation layer 311 and serves as the basis for forming the display encapsulation layer 311, so that the display encapsulation layer 311 is formed on the substrate layer 312. For example, the substrate layer 312 may be a polyimide (PI) layer.

[0113] Additionally, refer to Figure 6As shown, to enhance the tensile strength of the foldable screen 300, in related technologies, a flexible glass layer 350 and a substrate layer 360 can be provided between the cover plate 320 and the display module 310. The substrate layer 360 is disposed on the display module 310 and is typically a plastic layer. The flexible glass layer 350 is supported on the substrate layer 360. The flexible glass layer 350 is thin and easily bent, which can meet the needs of repeated folding and unfolding of the foldable screen 300. Furthermore, the flexible glass layer 350 has high hardness, which can enhance the tensile strength of the foldable screen 300, maintain the flatness of the foldable screen 300, and help improve the creases of the foldable screen 300. The flexible glass layer 350 has poor mechanical properties; by providing the substrate layer 360, the impact resistance of the flexible glass layer 350 can be enhanced, thereby improving the stability and reliability of the foldable screen 300.

[0114] However, the flexible glass layer 350 is easily bent and cannot effectively reduce the tensile deformation of the foldable screen 300. During long-term use, noticeable creases will still appear on the foldable screen 300, affecting its appearance and resulting in a poor user experience for foldable electronic devices. Furthermore, due to the thinness of the flexible glass layer 350, its mechanical properties are poor and its impact resistance is weak, making it prone to problems such as film breakage and delamination, thus affecting the lifespan of the foldable screen 300.

[0115] In view of this, the present application improves the structure of the foldable screen. The foldable screen includes a display module, with a first side and a second side on both sides of the thickness direction of the display module. A reinforcing layer is provided on at least one of the first and second sides of the display module. The reinforcing layer includes a substrate and multiple flexible glass portions, each of which is embedded in the substrate. The flexible glass portions are spaced apart along a first direction and extend along a second direction perpendicular to the first direction, penetrating both sides of the foldable screen. By spaced multiple flexible glass portions in the substrate, each flexible glass portion has a small width, high hardness, smaller deformation, and better tensile strength, which reduces the tensile deformation of the foldable screen, effectively improves the creases of the foldable screen, enhances the appearance of the foldable screen, and improves the user experience of the foldable electronic device. Furthermore, by embedding each flexible glass portion in the substrate, the substrate can better absorb deformation stress, enhancing the integrity and consistency of the reinforcing layer and extending the service life of the foldable screen.

[0116] The following provides a detailed description of the foldable screen according to the embodiments of this application.

[0117] Figure 7 This is a schematic diagram of a foldable screen provided in an embodiment of this application. Figure 8 This is a schematic diagram of another foldable screen structure provided in an embodiment of this application. Figure 9This is a schematic diagram of the structure of a third type of foldable screen provided in an embodiment of this application.

[0118] Reference Figures 7 to 9 As shown in any of the embodiments, the foldable screen 100a in this application includes a display module 110 and a reinforcing layer 120. For ease of explanation, this embodiment shows the thickness direction of the display module 110 (…). Figures 7 to 9 The two sides of the Z-direction are defined as the first side and the second side of the display module 110, respectively. The first side of the display module 110 corresponds to the display surface of the display module 110; in other words, the first side of the display module 110 is the surface on which image information is displayed. The second side of the display module 110 is the back side of the display module 110. A reinforcing layer 120 is disposed on at least one of the first side and the second side of the display module 110.

[0119] The display module 110 includes a display layer 111 and a substrate layer 112. The display layer 111 is the core functional layer of the display module 110. The display layer 111 can have multiple pixel units arranged in an array, and it can be equipped with driving circuits and thin-film transistors (TFTs). The TFTs and driving circuits control each pixel unit to achieve the function of displaying image information. The substrate layer 112 supports the display layer 111 and also serves as the basis for forming the display layer 111. The display layer 111 can be fabricated on the substrate layer 112. For example, the substrate layer 112 can be made of polyimide (PI).

[0120] For the reinforcing layer 120 disposed on at least one side of the display module 110, the reinforcing layer 120 on at least one side may include a substrate 121 and a plurality of flexible glass portions 122. The substrate 121 serves as the supporting base for the flexible glass portions 122, and each flexible glass portion 122 is embedded in the substrate 121 to form an integral reinforcing layer 120. The substrate 121 is made of polyimide, for example, and the flexible glass portions 122 are formed using ultra-thin flexible glass (UTG).

[0121] In other words, when the display module 110 has a reinforcing layer 120 on only one side, the reinforcing layer 120 includes a substrate 121 and a plurality of flexible glass portions 122 embedded in the substrate 121. When the display module 110 has reinforcing layers 120 on both sides, the reinforcing layers 120 on both sides of the display module 110 each include a substrate 121 and a plurality of flexible glass portions 122 embedded in the substrate 121; or, one of the reinforcing layers 120 on the first side and the reinforcing layers 120 on the second side of the display module 110 includes a substrate 121 and a plurality of flexible glass portions 122 embedded in the substrate 121, and the other includes a substrate 121 and a flexible glass layer 123a stacked on the substrate 121.

[0122] When the reinforcing layer 120 includes a substrate 121 and a plurality of flexible glass portions 122 embedded in the substrate 121, each flexible glass portion 122 is along a first direction ( Figures 7 to 9 The flexible glass portions 122 are spaced apart in the X direction shown in the diagram, and each flexible glass portion 122 is arranged along the second direction (…). Figures 7 to 9 The flexible glass portion 122 extends in the Y direction shown in the figure, and the second direction is perpendicular to the first direction. The flexible glass portion 122 extends through the opposite sides of the folding screen 100a in the second direction.

[0123] As mentioned earlier, the first direction is the arrangement direction of the first region 101, the bendable region 102, and the second region 103 of the foldable screen 100a, and the second direction is the extension direction of the pivot, or in other words, the extension direction of the folding pivot of the foldable screen 100a. By arranging each flexible glass portion 122 sequentially along the first direction and extending each flexible glass portion 122 along the second direction, each flexible glass portion 122 conforms to the folding method of the foldable screen 100a and does not obstruct the folding and unfolding of the foldable screen 100a.

[0124] By arranging multiple flexible glass portions 122 at intervals along the first direction, the flexible glass portions 122 have high hardness and small width (in the first direction), thereby improving the deformation resistance of each flexible glass portion 122. During long-term use of the foldable screen 100a, the foldable screen 100a is repeatedly folded and unfolded, resulting in smaller deformation of the flexible glass portions 122 and better tensile strength, which can improve the flatness of the reinforcing layer 120, and thus improve the overall flatness of the foldable screen 100a. Reducing the tensile deformation of the foldable screen 100a, especially at the junction of the bendable area 102 and the first area 101 and the second area 103 of the foldable screen 100a, can effectively improve the creases of the foldable screen 100a, enhance the appearance of the foldable screen 100a, and improve the user experience of the foldable electronic device 10.

[0125] Furthermore, by embedding each flexible glass portion 122 into the substrate 121, the flexible glass portion 122 and the substrate 121 together form an integral reinforcing layer 120, enhancing the integrity and consistency of the reinforcing layer 120. During the transition between the folded and unfolded states of the foldable screen 100a, the substrate 121 can absorb the stress generated by the deformation of the foldable screen 100a, reducing the impact of this stress on the flexible glass portion 122. Therefore, problems such as film layer breakage and delamination in the foldable screen 100a can be improved or even avoided, enhancing the reliability of the foldable screen 100a and extending its service life.

[0126] Reference Figure 7 or Figure 8 As shown, in some embodiments, the foldable screen 100a may have only one reinforcing layer 120, which includes a substrate 121 and a plurality of flexible glass portions 122 embedded in the substrate 121. Referring to... Figure 7 As shown, the reinforcing layer 120 can be disposed on the first side of the display module 110; in other words, the reinforcing layer 120 is disposed on the display side of the display module 110, and the reinforcing layer 120 is close to the front of the foldable screen 100a. (Refer to...) Figure 8 As shown, the reinforcing layer 120 can also be disposed on the second side of the display module 110. In other words, the reinforcing layer 120 is disposed on the back side of the display module 110, and the reinforcing layer 120 is close to the back of the folding screen 100a.

[0127] When a reinforcing layer 120 is provided in the foldable screen 100a, whether the reinforcing layer 120 is located near the front of the foldable screen 100a or near the back of the foldable screen 100a, the reinforcing layer 120 can play a role in resisting tension, which can reduce the tensile deformation of the foldable screen 100a, improve the crease of the foldable screen 100a, and enhance the appearance of the foldable screen 100a. This will not be elaborated further here.

[0128] Taking the foldable screen 100a applied to an inward-folding electronic device as an example, when the inward-folding electronic device is in a folded state, the front surfaces of the first region 101 and the second region 103 of the foldable screen 100a are relatively close. At this time, when the reinforcing layer 120 is positioned close to the back surface of the foldable screen 100a, more structural layers are transferred to the tensile strength of the reinforcing layer 120, resulting in better tensile performance of the foldable screen 100a. Similarly, taking the foldable screen 100a applied to an outward-folding electronic device as an example, when the outward-folding electronic device is in a folded state, the back surfaces of the first region 101 and the second region 103 of the foldable screen 100a are relatively close. At this time, when the reinforcing layer 120 is positioned close to the front surface of the foldable screen 100a, more structural layers are transferred to the tensile strength of the reinforcing layer 120, resulting in better tensile performance of the foldable screen 100a.

[0129] Reference Figure 9As shown, in some embodiments, the foldable screen 100a may have two reinforcing layers 120. For ease of explanation, this embodiment defines the two reinforcing layers 120 as a first reinforcing layer 120a and a second reinforcing layer 120b, respectively. The first reinforcing layer 120a is located on the first side of the display module 110, or in other words, it is disposed near the front of the foldable screen 100a. The second reinforcing layer 120b is located on the second side of the display module 110, or in other words, it is disposed near the back of the foldable screen 100a. At least one of the first reinforcing layer 120a and the second reinforcing layer 120b includes a substrate 121 and a plurality of flexible glass portions 122 embedded in the substrate 121.

[0130] By providing reinforcing layers 120 on both the first and second sides of the display module 110, both the upper and lower reinforcing layers 120 provide tensile resistance. The constraint of the display module 110 by the upper and lower reinforcing layers 120 enhances its stability, thereby improving the overall tensile resistance of the foldable screen 100a. Furthermore, the flexible glass portion 122 in the upper and lower reinforcing layers 120 can be designed to match the folding method of the foldable screen 100a, enhancing its creep resistance. Consequently, the foldable screen 100a's resistance to tensile deformation is strengthened, reducing or even eliminating creases, resulting in a better appearance and a superior user experience for the foldable electronic device 10.

[0131] For example, both the first reinforcing layer 120a and the second reinforcing layer 120b can be directly connected to the display module 110. In other words, no other structural layers are provided between the display module 110 and the first reinforcing layer 120a, or between the display module 110 and the second reinforcing layer 120b. The first reinforcing layer 120a and the second reinforcing layer 120b are respectively attached to the two side surfaces of the display module 110. In this way, the first reinforcing layer 120a and the second reinforcing layer 120b exert a stronger binding effect on the display module 110, enhancing the stability of the display module 110, improving the stability of the foldable screen 100a, and reducing or even eliminating creases in the foldable screen 100a. For example, the first reinforcing layer 120a can be bonded to the display surface of the display module 110, and the second reinforcing layer 120b can be bonded to the back surface of the display module 110.

[0132] Reference Figures 7 to 9As shown in any of the embodiments, the foldable screen 100a may further include a protective layer 130, which is located on the front side of the foldable screen 100a and is used to protect the foldable screen 100a from damage to the underlying structural layers, such as preventing the display module 110 from being worn or scratched. Furthermore, the protective layer 130 can enhance the overall structural strength of the foldable screen 100a, ensuring its reliability. For example, the protective layer 130 may be made of polyimide (PI).

[0133] Among them, reference Figure 7 or Figure 9 As shown, when a reinforcing layer 120 is provided on the first side of the display module 110, a protective layer 130 can cover the reinforcing layer 120 on the first side of the display module 110. For example, the protective layer 130 is bonded to the reinforcing layer 120 with adhesive. (Refer to...) Figure 8 As shown, when the first side of the display module 110 is not provided with the reinforcing layer 120, the protective layer 130 can be directly covered on the display module 110. For example, the protective layer 130 is bonded to the display module 110 with adhesive.

[0134] Reference Figures 7 to 9 As shown in any of the embodiments, the foldable screen 100a may further include a support plate 140, which is located on the back of the foldable screen 100a. The support plate 140 is used to support the structural layers located thereon, ensuring the overall structural strength and reliability of the foldable screen 100a. The support plate 140 can be a metal plate, such as a steel plate.

[0135] The support plate 140 may include a non-deformable portion 142 and a deformable portion 141. The deformable portion 141 is located in the middle region of the support plate 140, and the non-deformable portion 142 is connected to both sides of the deformable portion 141. The deformable portion 141 corresponds to the bendable area 102 of the foldable screen 100a, and the non-deformable portions 142 on both sides correspond to the first area 101 and the second area 103 of the foldable screen 100a, respectively. The non-deformable portion 142 of the support plate 140 cannot deform, thus ensuring the flatness of the first area 101 and the second area 103 of the foldable screen 100a. The deformable portion 141 of the support plate 140 can deform to meet the bending requirements of the bendable area 102 of the foldable screen 100a.

[0136] The non-deformable portion 142 of the support plate 140 can be a solid structure. The deformable portion 141 of the support plate 140 may, for example, include a plurality of support bars 1411, which are arranged along a first direction ( Figures 7 to 9As shown in the X direction, the support bars 1411 are arranged sequentially and can be connected by an elastic structure (or a retractable structure). Each support bar 1411 can move as the bendable area 102 of the foldable screen 100a bends, so as to realize the switching between the unfolded state and the folded state of the foldable screen 100a.

[0137] Among them, reference Figure 7 As shown, when the reinforcing layer 120 is not provided on the second side of the display module 110, the support plate 140 can be connected to the display module 110. For example, the support plate 140 and the display module 110 are bonded together by adhesive or adhesive foam. (Refer to...) Figure 8 or Figure 9 As shown, when a reinforcing layer 120 is provided on the second side of the display module 110, the support plate 140 can be connected to the reinforcing layer 120. For example, the support plate 140 and the reinforcing layer 120 are connected by adhesive or adhesive foam.

[0138] It should be noted that, compared to outward-folding electronic devices, the deformation of the folding screen 100a is greater during the transition between the unfolded and folded states in inward-folding electronic devices. For example, when the inward-folding electronic device is in the folded state, the folding screen 100a is teardrop-shaped. Therefore, compared to the folding screen 100a of outward-folding electronic devices, the folding screen 100a of inward-folding electronic devices exhibits greater tensile deformation and more noticeable creases, necessitating particularly robust tensile-resistant design. In this regard, the following detailed explanation of the reinforcing layer 120 in the folding screen 100a will be provided using the application of the folding screen 100a in an inward-folding electronic device as an example.

[0139] Figure 10 This is a schematic diagram of a reinforcing layer provided in an embodiment of this application. Figure 11 This is a schematic diagram of another reinforcing layer provided in an embodiment of this application. Figure 12 This is a schematic diagram of the structure of the third type of reinforcing layer provided in the embodiments of this application. Figure 13 This is a schematic diagram of the structure of the fourth type of reinforcing layer provided in the embodiments of this application.

[0140] Reference Figures 10 to 13 As shown in the figure, the reinforcing layer 120 includes a substrate 121 and a plurality of flexible glass portions 122 embedded in the substrate 121. When the foldable screen 100a is applied in an inward-folding electronic device, as the foldable screen 100a changes from an unfolded state to a folded state, the front surfaces of the foldable screen 100a gradually approach each other until they are relatively stacked. For the reinforcing layer 120, the flexible glass portions 122 are disposed close to the first surface of the reinforcing layer 120 (the side surface of the reinforcing layer 120 facing the front surface of the foldable screen 100a). When the foldable screen 100a is bent, the flexible glass portions 122 in the reinforcing layer 120 are closer together, and the flexible glass portions 122 can better perform their tensile resistance.

[0141] Therefore, in this embodiment, at least a portion of the flexible glass portions 122 in the reinforcing layer 120 can be located on the first surface of the reinforcing layer 120. This improves the tensile strength of the reinforcing layer 120, resulting in better resistance to tensile deformation of the folding screen 100a. Consequently, creases in the folding screen 100a can be reduced or even eliminated, improving its appearance.

[0142] Reference Figure 10 As shown, in some embodiments, each flexible glass portion 122 in the reinforcing layer 120 can be disposed on the first surface of the reinforcing layer 120. On the one hand, each flexible glass portion 122 located on the first surface of the reinforcing layer 120 can effectively exert tensile strength, and the bendable area 102, the first area 101, and the second area 103 of the foldable screen 100a all have good tensile strength. On the other hand, since all flexible glass portions 122 are exposed on the first surface of the reinforcing layer 120, it is convenient to connect each flexible glass portion 122 to the substrate 121, thereby improving the manufacturing efficiency of the reinforcing layer 120. For example, a whole-layer substrate 121 can be provided first, and then multiple grooves can be formed on the first surface of the substrate 121, after which each flexible glass portion 122 can be connected in each groove.

[0143] Reference Figure 11 or Figure 12 As shown, in some embodiments, in the reinforcing layer 120, the flexible glass portion 122 located in the bendable region 102 can be away from the front of the foldable screen 100a, while the flexible glass portions 122 located in the first region 101 and the second region 103 can be close to the front of the foldable screen 100a. Thus, when the foldable screen 100a is bent, each flexible glass portion 122 in the reinforcing layer 120 conforms to the bending trend of the foldable screen 100a. For example, when the foldable screen 100a is folded into a teardrop shape, each flexible glass portion 122 in the reinforcing layer 120 also folds into a teardrop shape. Furthermore, the overall bending degree of all flexible glass portions 122 in the reinforcing layer 120 is greater than the overall bending degree of the foldable screen 100a, resulting in stronger tensile strength in the reinforcing layer 120 and better resistance to tensile deformation in the foldable screen 100a, thus better reducing or even eliminating creases in the foldable screen 100a.

[0144] Reference Figure 11 As shown, as an example, the flexible glass portion 122 located in the bendable region 102 may be located in the middle region of the reinforcing layer 120 (thickness direction). Among all the flexible glass portions 122 located in the first region 101 and all the flexible glass portions 122 located in the second region 103, at least a portion of the flexible glass portions 122 are located on the first surface of the reinforcing layer 120.

[0145] For example, such as Figure 11 As shown, in the bendable region 102, the distance between the flexible glass portion 122 and the first surface of the reinforcing layer 120 is d1, and the distance between the flexible glass portion 122 and the second surface of the reinforcing layer 120 (the side surface of the reinforcing layer 120 facing away from the front of the folding screen 100a) is d2. d1 and d2 can be equal, or d1 can be greater than d2. Due to the overall thickness of the reinforcing layer 120, in the first region 101 and the second region 103, all flexible glass portions 122 can be located on the first surface of the reinforcing layer 120; or, the flexible glass portions 122 near the bendable region 102 are located in the middle region of the reinforcing layer 120 (thickness direction), and the flexible glass portions 122 near the two side edges of the folding screen 100a are located on the first surface of the reinforcing layer 120, so that the arrangement structure of each flexible glass portion 122 conforms to the bending trend of the folding screen 100a.

[0146] Reference Figure 12 As shown, as another example, the flexible glass portion 122 located in the bendable region 102 can be located on the second surface of the reinforcing layer 120. At least a portion of the flexible glass portions 122 in the first region 101 and all the flexible glass portions 122 in the second region 103 are located on the first surface of the reinforcing layer 120. With this configuration, the step difference between the flexible glass portions 122 in the bendable region 102 and the flexible glass portions 122 in the first region 101, and between the flexible glass portions 122 in the bendable region 102 and the flexible glass portions 122 in the second region 103, is greater. When the folding screen 100a is bent, the overall bending degree of all the flexible glass portions 122 in the reinforcing layer 120 is greater. The reinforcing layer 120 has better tensile strength, a stronger binding effect on the display module 110, and the folding screen 100a has better resistance to tensile deformation, thus better reducing or even eliminating creases in the folding screen 100a.

[0147] When the flexible glass portion 122 of the bendable region 102 moves away from the front of the foldable screen 100a, and the flexible glass portion 122 located in the first region 101 and the flexible glass portion 122 located in the second region 103 move closer to the front of the foldable screen 100a, the flexible glass portion 122 gradually moves closer to the front of the foldable screen 100a in the direction from the bendable region 102 to the first region 101 and in the direction from the bendable region 102 to the second region 103 (see...). Figure 12 (As shown). With this configuration, the flexible glass sections 122 are arranged regularly from the bendable area 102 of the foldable screen 100a to the first area 101 and the second area 103 on both sides. The tensile resistance of the reinforcing layer 120 to the foldable screen 100a is more balanced and consistent. The uniformity and consistency of the foldable screen 100a's resistance to tensile deformation are better, which helps to improve the flatness of the foldable screen 100a.

[0148] For example, in the foldable screen 100a, the flexible glass portion 122 of the bendable area 102 can be located on the second surface of the reinforcing layer 120. In the direction from the bendable area 102 to the first area 101 and in the direction from the bendable area 102 to the second area 103, the flexible glass portion 122 gradually approaches the front of the foldable screen 100a. The flexible glass portions 122 close to the two side edges of the foldable screen 100a are located on the first surface of the reinforcing layer 120.

[0149] Reference Figures 10 to 12 As shown in either case, whether all flexible glass portions 122 are located on the first surface of the reinforcing layer 120, or whether the flexible glass portions 122 in the bendable region 102 are away from the front of the foldable screen 100a, and the flexible glass portions 122 in the first region 101 and the second region 103 are close to the front of the foldable screen 100a, the width of each flexible glass portion 122 in the reinforcing layer 120 can be equal. This results in more uniform tensile strength of each flexible glass portion 122, better overall uniformity and consistency of the reinforcing layer 120, and a more balanced and consistent overall tensile strength. Furthermore, it facilitates the fabrication of each flexible glass portion 122, thus improving the manufacturing efficiency of the reinforcing layer 120.

[0150] With all flexible glass sections 122 having equal widths, the spacing between any two adjacent flexible glass sections 122 can be equal. That is, the flexible glass sections 122 are evenly spaced within the reinforcing layer 120. This results in more uniform tensile strength across different areas of the reinforcing layer 120, providing a more balanced tensile effect on the foldable screen 100a as a whole. The more balanced tensile strength of the first region 101 and the second region 103 of the foldable screen 100a reduces the overall internal stress of the foldable screen 100a and improves its overall flatness.

[0151] Reference Figure 13 As shown, in some embodiments, the widths of the flexible glass portions 122 in the reinforcing layer 120 can be designed differently. The width of the flexible glass portion 122 located in the bendable region 102 can be larger, while the widths of the flexible glass portions 122 located in the first region 101 and the second region 103 can be smaller. Alternatively, the width M1 of the flexible glass portion 122 located in the bendable region 102 can be greater than the width M2 of the flexible glass portion 122 located in the first region 101 and the second region 103.

[0152] By increasing the width of the flexible glass portion 122 in the bendable area 102, the tensile strength of the reinforcing layer 120 in the bendable area 102 can be enhanced, thereby improving the tensile strength of the bendable area 102 of the foldable screen 100a and improving the flatness of the bendable area 102 and its surrounding area. For creases that mainly appear at the boundaries between the bendable area 102 and the first area 101 and the second area 103, improving the flatness of the bendable area 102 and its surrounding area of ​​the foldable screen 100a can reduce or even eliminate the creases, thus improving the appearance of the foldable screen 100a.

[0153] By maintaining a small width for the flexible glass portion 122 in the first region 101 and the flexible glass portion 122 in the second region 103, it is beneficial to maintain the high hardness of the flexible glass portion 122 in the first region 101 and the second region 103, reduce the deformation of the flexible glass portion 122 in the first region 101 and the second region 103, and enhance the tensile strength of the reinforcing layer 120. Furthermore, this reduces the tensile deformation of the first region 101 and the second region 103, reduces the impact of the first region 101 and the second region 103 on the bendable region 102, improves the flatness of the foldable screen 100a, and improves or even eliminates the creases of the foldable screen 100a.

[0154] Wherein, when the width of the flexible glass portion 122 of the bendable region 102 is greater than the width of the flexible glass portion 122 of the first region 101 and the second region 103, the flexible glass portion 122 of the bendable region 102 can be located in the middle region of the reinforcing layer 120 (thickness direction) (see...). Figure 13 Alternatively, the flexible glass portion 122 of the bendable region 102 can also be located on the first surface of the reinforcing layer 120. Since the flexible glass portion 122 of the bendable region 102 has a larger width and occupies a larger space, the number of flexible glass portions 122 in the first region 101 and the second region 103 is smaller, and their distance from the center of the folding screen 100a is greater. Therefore, in the first region 101 and the second region 103, all flexible glass portions 122 can be located on the first surface of the reinforcing layer 120 (see...). Figure 13 Alternatively, the flexible glass portion 122 near the bendable region 102 is located in the middle region of the reinforcing layer 120 (thickness direction), and the flexible glass portion 122 away from the bendable region 102 is located on the first surface of the reinforcing layer 120.

[0155] Regardless of whether the flexible glass portion 122 is located on the surface of the reinforcing layer 120 or in the middle region (thickness direction) of the reinforcing layer 120, in this embodiment, the thickness of each flexible glass portion 122 in the reinforcing layer 120 can remain consistent. Specifically, the ratio of the thickness of the flexible glass portion 122 to the total thickness of the reinforcing layer 120 is ≥1 / 2, or in other words, the thickness of the flexible glass portion 122 is ≥1 / 2 of the total thickness of the reinforcing layer 120. This ensures that the flexible glass portion 122 occupies a larger thickness space in the reinforcing layer 120, effectively ensuring that the flexible glass portion 122 effectively exerts its tensile strength, guaranteeing that the reinforcing layer 120 has good tensile strength, thereby effectively reducing the tensile deformation of the folding screen 100a, improving the flatness of the folding screen 100a, and improving or even eliminating creases in the folding screen 100a.

[0156] The following provides a detailed description of the design of the first reinforcing layer 120a and the second reinforcing layer 120b when the reinforcing layer 120 in the foldable screen 100a includes the aforementioned first reinforcing layer 120a and second reinforcing layer 120b.

[0157] Figure 14 This is a schematic diagram of a first structure of the first reinforcing layer and the second reinforcing layer provided in an embodiment of this application. Figure 15 This is a schematic diagram of a second structure of the first and second reinforcing layers provided in an embodiment of this application. Figure 16 This is a schematic diagram of a third structure of the first and second reinforcing layers provided in the embodiments of this application. Figure 17 This is a schematic diagram of a fourth structure of the first and second reinforcing layers provided in the embodiments of this application. Figure 18 This is a fifth structural diagram of the first and second reinforcing layers provided in the embodiments of this application. Figure 19 This is a sixth structural schematic diagram of the first and second reinforcing layers provided in the embodiments of this application. Figure 20 This is a seventh structural diagram of the first and second reinforcing layers provided in the embodiments of this application.

[0158] Reference Figures 14 to 20 As shown in these figures, several different design structures of the first reinforcing layer 120a and the second reinforcing layer 120b are illustrated. It should be noted that these figures only show partial design structures of the first reinforcing layer 120a and the second reinforcing layer 120b. In addition to these figures, the first reinforcing layer 120a and the second reinforcing layer 120b may also include other design structures.

[0159] Among them, reference Figures 14 to 18As shown, in some embodiments, both the first reinforcing layer 120a and the second reinforcing layer 120b may include a substrate 121 and a plurality of flexible glass portions 122 embedded in the substrate 121. For ease of explanation, in this embodiment, the substrate 121 of the first reinforcing layer 120a is defined as the first substrate 121a, and the flexible glass portion 122 of the first reinforcing layer 120a is defined as the first flexible glass portion 122a. In other words, the first reinforcing layer 120a includes the first substrate 121a and a plurality of first flexible glass portions 122a embedded in the first substrate 121a. Correspondingly, in this embodiment, the substrate 121 of the second reinforcing layer 120b is defined as the second substrate 121b, and the flexible glass portion 122 of the second reinforcing layer 120b is defined as the second flexible glass portion 122b. In other words, the second reinforcing layer 120b includes the second substrate 121b and a plurality of second flexible glass portions 122b embedded in the second substrate 121b.

[0160] Since the first reinforcing layer 120a is disposed on the first side of the display module 110, it is close to the front surface of the foldable screen 100a. The first reinforcing layer 120a has relatively few structural layers contributing to tensile strength; its main function is to restrain the protective layer 130 located thereon, while the protective layer 130 itself has a relatively weak impact on the creases of the foldable screen 100a. Therefore, the first reinforcing layer 120a can be designed with regularity, and all the first flexible glass portions 122a in the first reinforcing layer 120a can be located on the first surface of the first reinforcing layer 120a.

[0161] In this way, the first surface of the first reinforcing layer 120a has strong tensile strength. When the foldable screen 100a is in a folded state, the first reinforcing layer 120a has a reinforcing binding effect on the foldable screen 100a, and the force exerted by the first reinforcing layer 120a on each area of ​​the foldable screen 100a is relatively balanced, which can improve the flatness of the foldable screen 100a. Furthermore, it facilitates the connection of each first flexible glass part 122a to the substrate 121, which can improve the manufacturing efficiency of the first reinforcing layer 120a.

[0162] Furthermore, the width of each first flexible glass portion 122a in the first reinforcing layer 120a can be equal, and the spacing between any two adjacent first flexible glass portions 122a can also be equal. Therefore, the first reinforcing layer 120a has good balance and consistency, and its overall tensile strength is more balanced, which helps improve the overall tensile strength of the folding screen 100a, enhances its flatness, and reduces or even eliminates creases. From a manufacturing perspective, the first reinforcing layer 120a facilitates the design and processing of the first substrate 121a, and also facilitates the corresponding connection between each first flexible glass portion 122a and the first substrate 121a, thus improving the manufacturing efficiency of the first reinforcing layer 120a.

[0163] For ease of explanation, in this embodiment, the width of the first flexible glass portion 122a is defined as the first width, and the distance between adjacent first flexible glass portions 122a is defined as the first distance.

[0164] Reference Figures 14 to 17 As shown in any embodiment, in the first reinforcing layer 120a, the widths of each first flexible glass portion 122a are equal, and the spacing between each adjacent first flexible glass portion 122a is equal. Similarly, in the second reinforcing layer 120b, the widths of each second flexible glass portion 122b are equal, and the spacing between each adjacent second flexible glass portion 122b is also equal. This configuration results in better balance and consistency of the second reinforcing layer 120b, and a more balanced overall tensile strength. This is beneficial for improving the overall tensile strength of the foldable screen 100a, enhancing the flatness of the foldable screen 100a, and facilitating the design and manufacturing of the second reinforcing layer 120b.

[0165] For ease of explanation, in this embodiment, the width of the second flexible glass portion 122b is defined as the second width, and the distance between adjacent second flexible glass portions 122b is defined as the second distance.

[0166] Reference Figure 14 As shown, in the first example, the second reinforcing layer 120b can adopt the same design as the first reinforcing layer 120a. The width of the second flexible glass portion 122b can be equal to the width of the first flexible glass portion 122a; in other words, the second width can be equal to the first width. Furthermore, the spacing between adjacent second flexible glass portions 122b can be equal to the spacing between adjacent first flexible glass portions 122a; in other words, the second spacing can be equal to the first spacing. Thus, the tensile strength of the second reinforcing layer 120b is similar to that of the first reinforcing layer 120a. Through the restraint of the display module 110 by the first reinforcing layer 120a and the second reinforcing layer 120b, the stability of the display module 110 can be enhanced.

[0167] Furthermore, the orthographic projection of each first flexible glass portion 122a in the first reinforcing layer 120a onto the second reinforcing layer 120b completely coincides with each second flexible glass portion 122b. In other words, each second flexible glass portion 122b in the second reinforcing layer 120b is directly opposite to each first flexible glass portion 122a in the first reinforcing layer 120a, and the structure of the second reinforcing layer 120b can be completely identical to the structure of the first reinforcing layer 120a. This good consistency between the first reinforcing layer 120a and the second reinforcing layer 120b is beneficial for improving the stability and reliability of the foldable screen 100a. Moreover, it facilitates the processing and manufacturing of the first reinforcing layer 120a and the second reinforcing layer 120b, thereby improving the manufacturing efficiency of the foldable screen 100a.

[0168] For example, such as Figure 14 As shown, each first flexible glass portion 122a in the first reinforcing layer 120a and each second flexible glass portion 122b in the second reinforcing layer 120b maintains a small width. The width of the first flexible glass portion 122a and the width of the second flexible glass portion 122b are both L0; in other words, the first width and the second width are both L0. Furthermore, the spacing between adjacent first flexible glass portions 122a and the spacing between adjacent second flexible glass portions 122b are both D0; in other words, the first spacing and the second spacing are both D0, and each first flexible glass portion 122a and each second flexible glass portion 122b are directly opposite each other. For example, the first width (or second width) L0 can be equal to the first spacing (or second spacing) D0.

[0169] in addition, Figure 14 The diagram illustrates how each of the second flexible glass portions 122b in the second reinforcing layer 120b is located on the first surface of the second reinforcing layer 120b. In other examples, with Figure 11 or Figure 12 Similarly, the second flexible glass portion 122b located in the bendable region 102 of the second reinforcing layer 120b can be located away from the front side of the foldable screen 100a, and the arrangement structure of each second flexible glass portion 122b in the second reinforcing layer 120b conforms to the bending trend of the foldable screen 100a. Among them, in the flexible glass portions 122 located in the first region 101 and the second region 103 of the second reinforcing layer 120b, all the second flexible glass portions 122b can be located on the first surface of the second reinforcing layer 120b, or the second flexible glass portions 122b near the bendable region 102 can be located in the middle region of the second reinforcing layer 120b (thickness direction), which will not be elaborated here.

[0170] Reference Figures 15 to 17 As shown in any one of the examples, in the second example, the width of each of the first flexible glass portions 122a in the first reinforcing layer 120a can be increased so that the width of the first flexible glass portion 122a is greater than the width of the second flexible glass portion 122b; in other words, the first width is greater than the second width. This enhances the tensile strength of the first reinforcing layer 120a, strengthens the binding effect of the first reinforcing layer 120a on the display module 110 below it and the protective layer 130 above it, thereby improving the overall tensile strength of the folding screen 100a, improving the flatness of the folding screen 100a, and reducing or even eliminating creases in the folding screen 100a.

[0171] Because the width of each first flexible glass portion 122a in the first reinforcing layer 120a is increased, the hardness of the area where the first flexible glass portion 122a is located is higher. In order to improve the overall balance and consistency of the first reinforcing layer 120a, the spacing between adjacent first flexible glass portions 122a can be reduced. Alternatively, the first spacing can be made less than or equal to the second spacing to maintain a smaller spacing between adjacent first flexible glass portions 122a, so as to avoid excessive performance differences between different areas of the first reinforcing layer 120a.

[0172] For example, such as Figures 15 to 17 As shown in either example, each second flexible glass portion 122b in the second reinforcing layer 120b can maintain a relatively small width, with the second width remaining L0, and the spacing between adjacent second flexible glass portions 122b remaining D0; in other words, the second spacing remains D0. Meanwhile, the width of each first flexible glass portion 122a in the first reinforcing layer 120a can be L1, and the spacing between adjacent first flexible glass portions 122a can be D1. Wherein, the first width L1 is greater than the second width L0, and the first spacing D1 is less than the second spacing D0.

[0173] in, Figure 15 The diagram shows that each of the second flexible glass portions 122b in the second reinforcing layer 120b is located on the first surface of the second reinforcing layer 120b. This arrangement provides more balanced tensile strength to the second reinforcing layer 120b, offering good tensile resistance to all areas of the folding screen 100a. Furthermore, it facilitates the processing and fabrication of the second reinforcing layer 120b.

[0174] Figure 16 and Figure 17 The diagram shows the second flexible glass portion 122b located in the bendable region 102 of the second reinforcing layer 120b, away from the front side of the foldable screen 100a, and the arrangement of the second flexible glass portions 122b in the second reinforcing layer 120b conforms to the bending trend of the foldable screen 100a. With this arrangement, the second reinforcing layer 120b exerts a stronger restraining effect on the foldable screen 100a, resulting in better overall tensile strength of the foldable screen 100a and making it easier to reduce or even eliminate creases in the foldable screen 100a. In the flexible glass portions 122b located in the first region 101 and the second region 103 of the second reinforcing layer 120b, all the second flexible glass portions 122b can be located on the first surface of the second reinforcing layer 120b (see [reference]). Figure 16 Alternatively, the second flexible glass portion 122b near the bendable region 102 is located in the middle region of the second reinforcing layer 120b (in the thickness direction) (see...). Figure 17 (This will not be elaborated upon here.)

[0175] When the width of each first flexible glass portion 122a in the first reinforcing layer 120a is greater than the width of each second flexible glass portion 122b in the second reinforcing layer 120b, and the spacing between adjacent first flexible glass portions 122a is less than the spacing between adjacent second flexible glass portions 122b, in other words, when the first width is greater than the second width and the first spacing is less than the second width, the ratio of the first width to the second width and the ratio of the first spacing to the second spacing can be designed according to the teardrop shape and size presented by the folding screen 100a in the folded state.

[0176] Reference Figure 18 As shown, in another embodiment, based on the fact that the widths of each first flexible glass portion 122a in the first reinforcing layer 120a are all equal and the spacing between each adjacent first flexible glass portion 122a is all equal, the second flexible glass portions 122b in the second reinforcing layer 120b can be designed differently. Specifically, in the second reinforcing layer 120b, the width of the second flexible glass portion 122b located in the bendable region 102 can be larger, while the width of the second flexible glass portion 122b located in the first region 101 and the second region 103 can be smaller. Alternatively, the width of the second flexible glass portion 122b in the bendable region 102 can be greater than the width of the flexible glass portions 122 in the first region 101 and the second region 103.

[0177] This design enhances the tensile strength of the second reinforcing layer 120b in the bendable area 102. Through the combined action of the first reinforcing layer 120a and the second reinforcing layer 120b, the tensile strength of the bendable area 102 of the foldable screen 100a is strengthened, improving the flatness of the bendable area 102 and its surrounding area. Furthermore, this improves the overall tensile strength of the foldable screen 100a, reduces or even eliminates creases, and enhances its appearance.

[0178] As an example, such as Figure 18 As shown, the width of the second flexible glass portion 122b located in the bendable region 102 can be greater than the width of the first flexible glass portion 122a. In other words, the width of the second flexible glass portion 122b located in the bendable region 102 can be greater than the first width. Furthermore, the width of each of the first flexible glass portions 122a in the first reinforcing layer 120a can be increased so that the width of the second flexible glass portion 122b located in the first region 101 and the second region 103 is less than the width of the first flexible glass portion 122a. In other words, the width of the second flexible glass portion 122b located in the first region 101 and the second region 103 is less than the first width.

[0179] Furthermore, the spacing between any two adjacent second flexible glass portions 122b can be equal, and the spacing between adjacent second flexible glass portions 122b can be greater than the spacing between adjacent first flexible glass portions 122a, or in other words, the second spacing can be greater than the first spacing.

[0180] For example, the width of the first flexible glass portion 122a can be L1, and the spacing between adjacent first flexible glass portions 122a can be D1; in other words, the first width can be L1, and the first spacing can be D1. The width of the second flexible glass portion 122b located in the bendable region 102 can be L2. The flexible glass portions 122 located in the first region 101 and the second region 103 can maintain a smaller width, and the width of the flexible glass portions 122 in the first region 101 and the second region 103 can be L0. The spacing between adjacent second flexible glass portions 122b can be D0; in other words, the second spacing is D0, and D0 is greater than D1.

[0181] Reference Figure 19 or Figure 20 As shown, in some other embodiments, the second reinforcing layer 120b may still include the second substrate 121b and a plurality of second flexible glass portions 122b embedded in the second substrate 121b, and the first reinforcing layer 120a may be different from the aforementioned first reinforcing layer 120a. The first reinforcing layer 120a may include the first substrate 121a and a full-layer flexible glass layer 123a, the flexible glass layer 123a being disposed on the first substrate 121a.

[0182] With this configuration, in the first reinforcing layer 120a, the flexible glass layer 123a covers the entire first substrate 121a. The large coverage area of ​​the flexible glass layer 123a provides good tensile strength, thus improving the tensile performance of the first reinforcing layer 120a. Furthermore, under the combined action of the first reinforcing layer 120a and the second reinforcing layer 120b, the overall tensile strength of the foldable screen 100a can be enhanced, improving the flatness of the foldable screen 100a and reducing or even eliminating creases in the foldable screen 100a.

[0183] Among them, reference Figure 19 As shown, in some examples, each of the second flexible glass portions 122b in the second reinforcing layer 120b can maintain a small width, and the spacing between adjacent second flexible glass portions 122b can be equal. For example, the width of the second flexible glass portion 122b remains L0, and the spacing between adjacent second flexible glass portions 122b remains D0, or in other words, the second width remains L0 and the second spacing remains D0.

[0184] It should be understood that, Figure 19The figure shows the second flexible glass portion 122b of the bendable region 102 away from the front side of the foldable screen 100a, and the arrangement of the second flexible glass portions 122b in the second reinforcing layer 120b conforms to the bending trend of the foldable screen 100a. In the figure, the second flexible glass portion 122b of the bendable region 102 is located on the second surface of the second reinforcing layer 120b. Of course, the second flexible glass portion 122b of the bendable region 102 can also be located in the middle region (thickness direction) of the second reinforcing layer 120b (see reference). Figure 11 (As shown). Alternatively, each of the second flexible glass portions 122b can be located on the first surface of the second reinforcing layer 120b (see reference). Figure 10 As shown in the image, this will not be elaborated upon further here.

[0185] Reference Figure 20 As shown, in some other examples, the width of at least a portion of the second flexible glass portion 122b in the second reinforcing layer 120b can be increased. As shown, the width of the second flexible glass portion 122b in the bendable region 102 can be increased; for example, the width of the second flexible glass portion 122b in the bendable region 102 can be increased to the aforementioned L2. Simultaneously, the widths of the flexible glass portions 122 in the first region 101 and the second region 103 can be consistent with the width of the second flexible glass portion 122b in the bendable region 102; for example, the width of each second flexible glass portion 122b in the second reinforcing layer 120b is increased to L2. Furthermore, in the figure, the second flexible glass portion 122b of the bendable region 102 is located on the second surface of the second reinforcing layer 120b. Of course, the second flexible glass portion 122b of the bendable region 102 can also be located in the middle region (thickness direction) of the second reinforcing layer 120b, or each second flexible glass portion 122b can be located on the first surface of the second reinforcing layer 120b (refer to...). Figure 10 As shown in the image, this will not be elaborated upon further here.

[0186] In other examples, only the width of the second flexible glass portion 122b of the bendable region 102 can be increased, while the width of the second flexible glass portions 122b of the first region 101 and the second region 103 remains relatively small. For example, the width of the second flexible glass portion 122b of the bendable region 102 can be increased to L2, while the width of the flexible glass portions 122b of the first region 101 and the second region 103 can be maintained at L0. This embodiment does not impose specific limitations on this.
