Description

Technical Field

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

[0002] Organic light-emitting diodes (OLEDs) are characterized by active light emission, high contrast, ultra-thinness, low temperature resistance, fast response speed, low power consumption, wide viewing angle, and strong shock resistance, which has led to their increasing use.

[0003] In related technologies, a display panel may include a display area and a bonding area. The display panel located in the bonding area is bonded to a driver chip to realize the transmission of electrical signals between the driver chip and the display panel. At the same time, the display panel in the bonding area is bent to the backlight side of the display panel to save space on the bottom bezel and achieve a narrower bottom bezel.

[0004] However, the aforementioned display panel is easily damaged. Summary of the Invention

[0005] In view of at least one of the above-mentioned technical problems, embodiments of this application provide a display module and display device that can alleviate the bending stress of the bent portion and prevent damage to the film layers in the bent portion, thereby protecting the display module and display device.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a display module, including: a flexible screen and a support assembly. The flexible screen includes a first display portion and a curved portion disposed adjacent to each other, and the support assembly is located on the backlight side of the flexible screen. The support assembly includes a first support portion near the curved portion and a second support portion away from the curved portion. At least one side of the first support portion in the thickness direction is attached to the curved portion, and the second support portion is attached to at least a portion of the first display portion. Along the direction from the second support portion to the first support portion, the first support portion includes a portion with gradually increasing thickness.

[0008] The display module provided in this application includes a flexible screen and a support assembly. The flexible screen includes a first display portion and a curved portion disposed adjacent to each other. The support assembly is located on the backlight side of the flexible screen. The support assembly includes a first support portion near the curved portion and a second support portion away from the curved portion. At least one side of the thickness direction of the first support portion is attached to the curved portion, and the second support portion is attached to at least a portion of the first display portion. Along the direction from the second support portion to the first support portion, the first support portion includes a portion with gradually increasing thickness, which is beneficial for gradually increasing the bending radius of the curved portion, reducing the bending stress of the curved portion, and preventing damage to the film layers in the curved portion, thereby protecting the display module and display device. In addition, the fact that at least one side of the thickness direction of the first support portion is attached to the curved portion provides better support for the curved portion, which is beneficial for maintaining and fixing the bending shape of the curved portion, improving the curved portion's resistance to external impact, and alleviating the deformation caused by external impact (e.g., bumps) to the curved portion, thereby further alleviating the stress on the curved portion and further reducing the impact on the display effect of the display module.

[0009] In one possible implementation, the support assembly includes a shim and a support member, the shim supporting the support member, the support member being located on both sides of at least a portion of the shim in the thickness direction, and the support member located on the side of the shim facing the first display portion being in contact with the first display portion.

[0010] What can be achieved is that the thickness of the first support part gradually increases at the end closest to the second support part.

[0011] This makes the transition between the first and second support parts smoother, which helps reduce the bending stress in the bent part.

[0012] In one possible implementation, the first support portion includes a first support member, which includes a plurality of sub-support members. The plurality of sub-support members are arranged along the curved portion, and at least some of the adjacent sub-support members abut against each other.

[0013] In this way, the first shim can provide better protection for the bent part during the bending process, which is conducive to maintaining and fixing the bending state of the bent part.

[0014] What is possible is that each sub-shield piece fits snugly against the curved section;

[0015] It is possible for every two adjacent sub-elevator pieces to abut against each other;

[0016] What can be achieved is that the cross-sectional width of the sub-elevator gradually decreases from the end closest to the bend to the end furthest from the bend in the direction of the radial direction of the bend.

[0017] It is possible to have the surface of the sub-elevator away from the bend have a curved cross-section along the radial direction of the bend, with the line connecting the two ends of the curve being closer to the bend than the middle of the curve; or, the cross-section of the sub-elevator along the radial direction of the bend is fan-shaped, with the arc edge of the fan-shaped part fitting against the bend, and the straight edges of the fan-shaped parts of each pair of adjacent sub-elevators abutting each other.

[0018] In one possible implementation, the shim of the first support portion includes a second shim. Along the thickness direction of the first display portion, the second shim includes a first surface and a second surface disposed opposite to each other, with the first surface facing the first display portion and the second surface facing away from the first display portion.

[0019] It is possible to gradually increase the distance between the first surface and the second surface along the end of the first display portion away from the curved portion to the end closer to the curved portion;

[0020] In this way, the bending radius of the bending part can be gradually increased, the bending stress of the bending part can be reduced, and the bending shape of the bending part can be maintained and fixed.

[0021] What can be achieved is that the hardness of the shim ranges from 5 Shore A to 200 Shore A;

[0022] It is possible to have a hardness greater than or equal to that of the first raised component in the first support section.

[0023] In one possible implementation, the curved portion includes a first end close to the first display portion and a second end away from the first display portion;

[0024] The first surface is flat and is attached to the first display part; or, the first surface is curved and is attached to the first end, and the line connecting the two ends of the first surface is farther away from the second surface than the middle of the first surface;

[0025] What is possible is that the second surface is curved and fits the second end, and the line connecting the two ends of the second surface is farther away from the first surface than the middle of the second surface.

[0026] In one possible implementation, the curved portion includes an intermediate connecting section located between the first end and the second end, and the second shim includes a third surface, with the first surface and the second surface connected by the third surface.

[0027] The third surface is curved and fits at least part of the intermediate connecting segment. The line connecting the two ends of the third surface is closer to the first display part than the middle part of the third surface; or, the third surface is flat and is spaced apart from the intermediate connecting segment.

[0028] In this way, the third surface can further alleviate the influence of bending stress on each membrane layer, help maintain and fix the bending shape of the bending part, and protect the bending part.

[0029] In one possible implementation, the second support portion includes a third support portion connected to the second support portion. The flexible screen includes a binding portion located on the backlight side of the first display portion and connected to the first display portion via a bending portion. The third support portion is located between the first display portion and the binding portion. The support portion located on the side of the third support portion away from the first display portion is attached to the binding portion, and the support portion located on the side of the third support portion facing the first display portion is attached to the first display portion.

[0030] In this way, the third shim can lift the first and second supports, thereby improving the support capacity of the supports for the flexible screen.

[0031] It is possible to have the surface of the third shim closest to the first display part and the first surface located on the same plane;

[0032] What can be achieved is that the surface of the third shim that is away from the first display part smoothly transitions to the second surface;

[0033] It is possible to integrate the third and second shims into a single structure.

[0034] It is possible to have the hardness of the third shim being greater than or equal to the hardness of the second shim.

[0035] In one possible implementation, the curved portion encloses and forms a receiving area, and the support component is located in a portion of the receiving area;

[0036] It is possible that the display module also includes a filler that fills another portion of the accommodating area.

[0037] This provides better support and protection for all parts of the bend.

[0038] In one possible implementation, the display module further includes a cover plate located on the light-emitting side of the first display section, and the curved section includes a curved display section close to the side of the first display section;

[0039] A light adjustment component is provided between the cover plate and the curved display section, and the light adjustment component is attached between the flexible screen and the cover plate;

[0040] It is possible to have a privacy layer installed on the side of the light adjustment component facing away from the curved display section, with the privacy layer located on the side of the light adjustment component facing the cover plate.

[0041] It is possible to have a light-shielding layer provided on the side of the light adjustment component away from the curved display part, the light-shielding layer being connected to the privacy layer, and the light-shielding layer extending along the thickness direction of the first display part;

[0042] This can correct the display distortion of the curved display section.

[0043] What is possible is that the refractive index of the side of the flexible screen closest to the light-adjusting component is equal to the refractive index of the light-adjusting component.

[0044] A second aspect of this application provides a display device including the display module described in the first aspect.

[0045] The display device provided in this application embodiment may include a display module, which includes a flexible screen and a support assembly. The flexible screen includes a first display portion and a curved portion disposed adjacent to each other, and the support assembly is located on the backlight side of the flexible screen. The support assembly includes a first support portion near the curved portion and a second support portion away from the curved portion. At least one side of the thickness direction of the first support portion is attached to the curved portion, and the second support portion is attached to at least a portion of the first display portion. Along the direction from the second support portion to the first support portion, the first support portion includes a portion with gradually increasing thickness, which is beneficial for gradually increasing the bending radius of the curved portion, reducing the bending stress of the curved portion, and preventing damage to the film layers in the curved portion, thereby protecting the display module and the display device. In addition, the fact that at least one side of the thickness direction of the first support portion is attached to the curved portion provides better support for the curved portion, which is beneficial for maintaining and fixing the bending shape of the curved portion, improving the curved portion's resistance to external impact, and alleviating the deformation caused by external impact (e.g., bumps) to the curved portion, thereby further alleviating the stress on the curved portion and further reducing the impact on the display effect of the display module.

[0074] In related technologies, a display panel may include a display area, a bending area, and a bonding area. The display panel located in the bonding area is bonded to a driver chip, thereby enabling electrical signal transmission between the driver chip and the display panel. By bending the display panel in the bending area, the display panel in the bonding area is bent to the backlight side of the display panel in the display area, thereby saving space on the bottom bezel and achieving a narrower bottom bezel.

[0075] However, because the display panel in the bending area is in a bent state, the bending stress on each film layer in the bending area is relatively large, which can easily cause the film layers in the bending area to peel off from each other or even be damaged (for example, causing display abnormalities). In addition, the bending area of ​​the display panel is located at the end of the display panel. During the manufacturing, storage, and transportation of the display panel, the bending area is more susceptible to impacts, which can lead to increased deformation, further increasing the stress on the bending area and thus further affecting the display effect.

[0076] Based on at least one of the aforementioned technical problems, embodiments of this application provide a display module and a display device. The display module includes a flexible screen and a support assembly. The flexible screen includes a first display portion and a curved portion disposed adjacent to each other. The support assembly is located on the backlight side of the flexible screen. The support assembly includes a first support portion near the curved portion and a second support portion away from the curved portion. At least one side of the thickness direction of the first support portion is attached to the curved portion, and the second support portion is attached to at least a portion of the first display portion. Along the direction from the second support portion to the first support portion, the first support portion includes a portion with gradually increasing thickness, which is beneficial for gradually increasing the bending radius of the curved portion, reducing the bending stress of the curved portion, and preventing damage to the film layers in the curved portion, thereby protecting the display module and the display device. In addition, the fact that at least one side of the thickness direction of the first support portion is attached to the curved portion provides better support for the curved portion, which is beneficial for maintaining and fixing the bending shape of the curved portion, improving the curved portion's resistance to external impact, alleviating the deformation caused by external impact (e.g., bumps), further alleviating the stress on the curved portion, and further reducing the impact on the display effect of the display module.

[0077] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0078] The following will combine Figures 1-12 The display device provided in the embodiments of this application will be described.

[0079] This application provides a display device, which includes a display module 10. The display device can be a mobile or fixed terminal such as an electronic paper device, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, smart bracelet, smartwatch, supercomputer, or navigator.

[0080] The following describes the display module 10 provided in the embodiments of this application.

[0081] See Figure 1The display module 10 may include a first direction X, a second direction, and a third direction Z, all of which are different. The first direction X and the second direction can be any two different directions parallel to the display module 10 (i.e., the first display portion 110a), and the third direction Z can be any direction intersecting the display module 10 (i.e., the first display portion 110a). For example, the first direction X, the second direction, and the third direction Z can be perpendicular to each other. For example, the first direction X can be the length direction of the display module 10, the second direction can be the width direction of the display module 10, and the third direction Z can be the thickness direction of the display module 10. The length, width, and thickness in the embodiments of this application are merely for descriptive convenience and do not imply any limitation on the dimensions. For example, the width can be greater than, equal to, or less than the length.

[0082] See Figure 1 The display module 10 may include a flexible screen 110, which may be an organic light-emitting diode (OLED) display or a micro light-emitting diode (Micro LED or μLED) display.

[0083] The flexible screen 110 may include a light-emitting side and a backlight side disposed opposite to each other along the thickness direction (third direction Z). The light-emitting side can be used to display images. The backlight side is the side opposite to the light-emitting side along the thickness direction of the flexible screen 110. Figure 1 The arrow 'g' in the diagram indicates the direction in which the light ray is emitted.

[0084] The flexible screen 110 provided in the embodiments of this application will be described below.

[0085] See Figure 1 The flexible screen 110 may include a first display portion 110a and a curved portion 110b, with the first display portion 110a and the curved portion 110b disposed adjacent to each other. The curved portion 110b may be located on at least one side of the first display portion 110a. For example, the curved portion 110b may be located on at least one side of the first display portion 110a along a first direction X, and / or, the curved portion 110b may be located on at least one side of the first display portion 110a along a second direction. This embodiment of the application will be described using the example of the curved portion 110b being located on the side of the first display portion 110a along the first direction X.

[0086] For example, the flexible screen 110 may further include a bonding portion 110c, which can be used to bond the driver chip 180, etc. A bending portion 110b is located between the first display portion 110a and the bonding portion 110c, and can be used to connect the first display portion 110a and the bonding portion 110c. By bending the bending portion 110b, the bonding portion 110c can be bent to the backlight side of the first display portion 110a, thereby reducing the bezel width of the display module 10.

[0087] See some examples. Figure 2 The side of the curved portion 110b closest to the first display portion 110a can have a display function, thereby increasing the display area of ​​the flexible screen 110 and improving its screen-to-body ratio. The curved portion 110b may include a curved display portion 114b near the first display portion 110a and a curved connecting portion 115b away from the first display portion 110a. The curved connecting portion 115b is located between the curved display portion 114b and the bonding portion 110c, and can be used to connect the curved display portion 114b and the bonding portion 110c. The first display portion 110a, the curved display portion 114b, the curved connecting portion 115b, and the bonding portion 110c are arranged sequentially. The curved display portion 114b is bent towards the cover plate 161. In other examples, the side of the curved portion 110b closest to the first display portion 110a may not have a display function, thereby reducing the energy consumption of the flexible screen 110. In addition, one or more of the curved connecting portion 115b and the binding portion 110c may or may not have a display function, and the embodiments of this application do not limit this.

[0088] The following describes the support component 190 provided in the embodiments of this application.

[0089] See Figure 1 The display module 10 may further include a support assembly 190, which may be located on the backlight side of the flexible screen 110. The support assembly 190 may include a padding member 120 and a support member 130. The padding member 120 may support the support member 130, and the support member 130 may be located on both sides of at least a portion of the padding member 120 in the thickness direction. For example, the support member 130 may be located on both sides of the thickness direction of a second padding member 122, and / or, the support member 130 may be located on both sides of the thickness direction of a third padding member 123. At least a portion of the support member 130 located on the side of the padding member 120 facing the first display portion 110a may be in contact with the first display portion 110a.

[0090] For example, see Figure 2 and Figure 9The support assembly 190 may include a first support portion 191 near the bend portion 110b and a second support portion 192 away from the bend portion 110b. At least one side of the first support portion 191 in the thickness direction may be in contact with the bend portion 110b, and the second support portion 192 may be in contact with at least a portion of the first display portion 110a.

[0091] For example, see Figure 2 and Figure 9 Along the direction from the second support portion 192 to the first support portion 191, the first support portion 191 may include a portion with gradually increasing thickness. This facilitates a gradual increase in the bending radius of the bent portion 110b, reducing the bending stress of the bent portion 110b and preventing damage to the film layers within the bent portion 110b, thereby protecting the display module 10 and the display device. Furthermore, at least one side of the first support portion 191 in the thickness direction can be in contact with the bent portion 110b, providing better support for the bent portion 110b. This helps maintain and fix the bending shape of the bent portion 110b, improving its resistance to external impacts and mitigating deformation caused by external impacts (e.g., bumps). This further alleviates the stress on the bent portion 110b, further reducing the impact on the display effect of the display module 10. For example, the thickness of the first support portion 191 near the second support portion 192 can be gradually increased, so that the transition between the first support portion 191 and the second support portion 192 is relatively smooth, which is beneficial to reducing the bending stress of the bent portion 110b.

[0092] The support member 130 provided in the embodiments of this application will be described below.

[0093] The support component 190 may include a support member 130, which is located on the backlight side of the flexible screen 110 and can be bonded to the flexible screen 110. In this embodiment, terms such as "connection," "bonding," and "linking" can refer to direct bonding or indirect bonding via other structural components (structural film layers). That is, the support member 130 can be directly bonded to the flexible screen 110 or indirectly bonded via other structural components. The support member 130 can protect the flexible screen 110 and provide certain support for it.

[0094] For example, the support member 130 may include a first support member 131, located on the backlight side of the first display unit 110a, which can be attached to the first display unit 110a and provides support for it. The support member 130 may also include a second support member 132, which can be attached to the binding part 110c and provides support for it. The support member 130 may include at least one of the first support member 131 and the second support member 132. In some other examples, the support member 130 may not be provided.

[0095] This application embodiment is illustrated by taking the simultaneous provision of a first support member 131 and a second support member 132 as an example.

[0096] See Figure 1 The first support member 131 and the second support member 132 can be spaced apart, so that at least part of the backlight side of the curved portion 110b is not provided with the support member 130, which is beneficial to the bending performance of the curved portion 110b and avoids the support member 130 from hindering the bending of the curved portion 110b. In addition, the force exerted by the support member 130 on the curved portion 110b can be reduced or avoided, thereby relieving the stress on the curved portion 110b. The support member 130 may be located only on the backlight side of the first display portion 110a and the side of the bonding portion 110c facing the first display portion 110, and not on the backlight side of the curved portion 110b. Alternatively, at least one of the first support member 131 and the second support member 132 may extend to a portion of the backlight side of the curved portion 110b.

[0097] The following describes the shim 120 provided in the embodiments of this application.

[0098] See Figure 1 The support assembly 190 may include a shim 120, which may be located on the backlight side of the flexible screen 110 and may be attached to at least a portion of the curved portion 110b. With this configuration, the shim 120 can provide better support for the curved portion 110b, improving its resistance to external impacts, mitigating deformation caused by external impacts (e.g., bumps), thereby reducing stress on the curved portion 110b, preventing the film layers in the curved portion 110b from peeling off, and avoiding damage to the film layers, thus minimizing the impact on the display effect of the display module 10.

[0099] For example, at least a portion of the shim 120 may be located between the first support 131 and the second support 132. For instance, the shim 120 may include a first shim 121, a second shim 122, and a third shim 123. Figure 10aAt least one of the following. The first support member 131 and the second support member 132 may be located on both sides of the thickness direction of the second shim member 122 and / or the third shim member 123. For example, the first support member 131 and the second support member 132 may cover at least a portion of the surfaces on both sides of the thickness direction of the second shim member 122 and / or the third shim member 123.

[0100] The first shim 121 provided in the embodiments of this application will be described below.

[0101] See Figure 10a and Figure 10b The first support portion 191 may include a first raising member 121 in the raising member 120. The first raising member 121 may include a plurality of sub-raising members 1211, which are arranged along the bending direction of the curved portion 110b. For example, each sub-raising member 1211 may fit against the curved portion 110b, and at least some adjacent sub-raising members 1211 abut against each other. This embodiment of the application will be described using the example of adjacent two sub-raising members 1211 abutting against each other.

[0102] See Figure 3 and Figure 4 Multiple sub-elevation elements 1211 can be installed on the backlight side of the bent portion 110b before it is bent. Since each sub-elevation element 1211 is independently installed, the hardness of each individual sub-elevation element 1211 is relatively low, thus minimizing its impact on the bending performance of the bent portion 110b and reducing its obstruction to bending. Furthermore, the multiple sub-elevation elements 1211 can provide support to the bent portion 110b during the bending process, improving its resistance to external impacts and providing better protection during bending. During the bending process, multiple sub-elevators 1211 ensure uniform stress distribution across the bent portion 110b, improving the controllability of the bending process and reducing the likelihood of sharp bends. This allows for a smooth transition between the bent portion 110b, the first display portion 110a, and the bonding portion 110c, thereby improving the yield rate of the narrow bezel technology. Furthermore, after the bent portion 110b is formed, the adjacent sub-elevators 1211 abut against each other, which helps maintain and fix the bent state of the bent portion 110b. The first elevator 121 can cover a portion or all of the bent portion 110b, or it can extend to a portion of the first display portion 110a and / or the bonding portion 110c.

[0103] For example, the sub-elevator 1211 can be elastic, so that when two adjacent sub-elevators 1211 abut against each other, they will not exert excessive force on the flexible screen 110, thereby reducing the impact of the sub-elevator 1211 on the flexible screen 110.

[0104] Understandably, during the bending process of the bending portion 110b, if the bending portion 110b is subjected to an external force impact, the two adjacent sub-elevation members 1211 can abut against each other to form mutual support, thereby alleviating the deformation of the bending portion 110b caused by the external force, thereby alleviating the stress on the bending portion 110b, alleviating the phenomenon of the film layers in the bending portion 110b peeling off from each other, and avoiding damage to the film layers in the bending portion 110b (e.g., metal trace layer breakage), so as to reduce the impact on the display effect of the display module 10.

[0105] For example, the cross-sectional width of the sub-elevator 1211 along the radial direction of the bend 110b gradually decreases from the end near the bend 110b to the end away from the bend 110b. This configuration results in a larger cross-sectional width at the end of the sub-elevator 1211 near the bend 110b, leading to a larger contact area between the sub-elevator 1211 and the bend 110b, thus providing better support for the bend 110b. In this embodiment, when the cross-sectional width of the sub-elevator 1211 gradually decreases along the radial direction of the bend 110b, it can alleviate the impact of excessive interaction force between adjacent sub-elevators 1211 on the bending performance of the bend 110b, reduce stress on the flexible screen 110, and prevent excessive force exerted by the sub-elevator 1211 on the flexible screen 110, which could lead to peeling or damage to the film layers in the flexible screen 110.

[0106] See Figure 4 and Figure 6 The surface of the sub-elevator 1211 facing the curved portion 110b is adapted to the shape of the curved portion 110b, thereby improving the assemblability of the sub-elevator 1211 and the curved portion 110b. In addition, it allows the sub-elevator 1211 to fit more tightly with the curved portion 110b, thereby providing better support for the curved portion 110b.

[0107] See Figure 3 and Figure 4The surface of the sub-elevator 1211 away from the bending portion 110b is curved, and the curved surface bends in the direction away from the bending portion 110b. That is, the cross-section of the surface of the sub-elevator 1211 away from the bending portion 110b along the radial direction of the bending portion 110b is a curve, and the curve bends in the direction away from the bending portion 110b. This makes the force between two adjacent sub-elevator 1211 more uniform, and stress concentration is less likely to occur on the sub-elevator 1211, thus making the force exerted by the sub-elevator 1211 on the flexible screen 110 more uniform. Here, "the curve bends in the direction away from the bending portion 110b" means that the line connecting the two ends of the curve is closer to the bending portion than the middle of the curve.

[0108] See Figure 5 and Figure 6 The sub-support piece 1211 has a fan-shaped cross-section along the radial direction of the curved portion 110b, with the arc edge of the fan conforming to the curved portion 110b. The straight edges of the fan shapes of every two adjacent sub-support pieces 1211 abut against each other, resulting in a larger contact area between adjacent sub-support pieces 1211 and better mutual support between them. This further enhances the support effect of the sub-support pieces 1211 on the flexible screen 110, better maintaining and fixing the curved state of the curved portion 110b. Furthermore, when the flexible screen 110 is subjected to external forces, the deformation of the sub-support pieces 1211 is smaller, thus mitigating the deformation of the curved portion 110b under external forces. Secondly, stress concentration is less likely to occur on the sub-support pieces 1211, resulting in a more uniform force exerted by the sub-support pieces 1211 on the flexible screen 110. For example, multiple fan-shaped sub-support pieces 1211 can be spliced ​​together to form an arc shape.

[0109] It is understandable that the shape of the cross-section of the sub-elevation member 1211 along the radial direction of the curved portion 110b can also be other regular or irregular shapes, as long as it can provide support for the flexible screen 110. Any two sub-elevation members 1211 among the plurality of sub-elevation members 1211 can have the same or different shapes.

[0110] In some examples, the sub-elevation element 1211 can be strip-shaped, extending along the second direction of the flexible screen 110, and multiple strip-shaped sub-elevation elements 1211 are arranged along the bending direction of the curved portion 110b. This configuration simplifies the structure of the multiple sub-elevation elements 1211 and simplifies the manufacturing process. Furthermore, without affecting the bending performance of the curved portion 110b, the sub-elevation elements 1211 provide good support for the flexible screen 110 along the second direction. In other examples, the sub-elevation element 1211 can be a protrusion, and multiple sub-elevation elements 1211 are arranged along the bending direction of the curved portion 110b to form a sub-elevation element group. Multiple sub-elevation element groups can be arranged along the second direction. This configuration results in a more uniform distribution of the multiple sub-elevation elements 1211 on the curved portion 110b, thereby providing more uniform support for the curved portion 110b.

[0111] The second shim 122 provided in the embodiments of this application will be described below.

[0112] See Figure 7 The first support portion 191 may include a second elevation member 122 along the thickness direction (third direction Z) of the first display portion 110a. The second elevation member 122 includes a first surface 1221 and a second surface 1222 disposed opposite to each other. The first surface 1221 faces the first display portion 110a, and the second surface 1222 faces away from the first display portion 110a. At least one of the first surface 1221 and the second surface 1222 may fit into the curved portion 110b.

[0113] See Figure 7 Along the first display portion 110a from the end away from the curved portion 110b to the end near the curved portion 110b (i.e., in the first direction X, from the first display portion 110a to the curved portion 110b), the distance D between the first surface 1221 and the second surface 1222 gradually increases. This allows for a gradual increase in the bending radius of the curved portion 110b, reducing the bending stress of the curved portion 110b and facilitating the maintenance and fixation of its curved shape. When the curved portion 110b is subjected to external force, the second shim 122 provides support to the curved portion 110b, mitigating deformation under external force and thus protecting it. See also... Figure 8 Since the bending portion 110b only increases the bending radius of the bending portion 110b, it does not increase the thickness H1 of the display module 10 corresponding to the first display portion 110a. The thickness of the display module 10 corresponding to the bending portion 110b is H1 + H2, and the difference between these two thicknesses is H2. This ensures that the display module 10 has a large area that is relatively thin, which is beneficial for the thinning and lightening of the display module 10.

[0114] See Figure 7The curved portion 110b may include a first end 111b near the first display portion 110a and a second end 112b away from the first display portion 110a. The curved portion 110b may also include an intermediate connecting segment 113b located between the first end 111b and the second end 112b. The intermediate connecting segment 113b can be used to connect the first end 111b and the second end 112b. The second shim 122 can be fitted with at least one of the first end 111b, the second end 112b, and the intermediate connecting segment 113b. One of the first surface 1221 and the second surface 1222 can be a curved surface, and the other can be a flat surface; alternatively, both of the first surface 1221 and the second surface 1222 can be curved surfaces.

[0115] See some examples. Figure 7 The first surface 1221 can be flat and is attached to the first display portion 110a (e.g., attached to the first display portion 110a via the first support member 131). The first surface 1221 can provide good support for this part of the first display portion 110a, and can also prevent the second shim 122 from affecting the flatness of the light-emitting side of the flexible screen 110, thereby increasing the display area of ​​the first display portion 110a and ensuring the display effect of the flexible screen 110. The second surface 1222 can be curved and is attached to the second end 112b (e.g., attached to the second end 112b via the second support member 132). The second surface 1222 can be bent toward the first surface 1221 (e.g., the line connecting the two ends of the second surface 1222 is farther away from the first surface 1221 than the middle of the second surface 1222). With this configuration, the second surface 1222 can gradually increase the bending radius of the bent portion 110b, reducing the bending stress of the bent portion 110b and thus mitigating the impact of bending stress on the various film layers. This is beneficial for maintaining and fixing the bending shape of the bent portion 110b. When the bent portion 110b is subjected to external force, the second shim 122 can provide support for the bent portion 110b, mitigating the deformation of the bent portion 110b under external force and thus protecting the bent portion 110b. Since the second surface 1222 faces the backlight side of the first display portion 110a, the second surface 1222 will not affect the flatness of the light-emitting side of the flexible screen 110. The slope of the second surface 1222 can be set to be smaller, allowing the second surface 1222 to bend slowly, thereby further increasing the bending radius of the second end 112b of the bent portion 110b and further mitigating the impact of bending stress on the various film layers.

[0116] In other examples, the first surface 1221 can be curved, and it is attached to the first end 111b. The first surface 1221 is bent toward the second surface 1222 (for example, the line connecting the two ends of the first surface 1221 is farther away from the second surface 1222 than the middle of the first surface 1221). The first surface 1221 can alleviate the influence of bending stress on each film layer, help maintain and fix the bending shape of the bent portion 110b, and protect the bent portion 110b. The principle has been explained and will not be repeated here. The second surface 1222 can be flat and is attached to the binding portion 110c. The second surface 1222 can provide better support for the binding portion 110c, and can also prevent the second shim 122 from affecting the flatness of the binding portion 110c, thereby increasing the area of ​​the binding portion 110c.

[0117] See other examples. Figure 9 The first surface 1221 can be curved and is attached to the first end 111b, bending towards the second surface 1222. The second surface 1222 can also be curved and is attached to the second end 112b, bending towards the first surface 1221. The first and second surfaces 1221 can alleviate the influence of bending stress on each film layer, help maintain and fix the bending shape of the bent portion 110b, and protect the bent portion 110b. The principle has been explained and will not be repeated here.

[0118] It is understood that the shim 120 may be provided with one of a first shim 121 and a second shim 122, for example, the first shim 121 ( Figure 1 ) or second shim 122 ( Figure 2 See also Figure 10a and Figure 10b The shim 120 can also be provided with a first shim 121 and a second shim 122 at the same time, so as to better protect the bent part 110b and maintain and fix the bent shape of the bent part 110b.

[0119] In some embodiments, see Figure 7 , Figure 9 and Figure 11 The second shim 122 also includes a third surface 1223, through which the first surface 1221 and the second surface 1222 can be connected. See also Figure 9 and Figure 11The third surface 1223 can be curved, and it is attached to at least a portion of the intermediate connecting segment 113b. The third surface 1223 is curved toward the curved portion 110b (for example, the line connecting the two ends of the third surface 1223 is closer to the first display portion 110a than the middle of the third surface 1223). This configuration further mitigates the impact of bending stress on the various film layers, helps maintain and fix the bending shape of the curved portion 110b, and provides protection for the curved portion 110b. The principle has been explained and will not be repeated here. Alternatively, see [link to relevant documentation]. Figure 7 The third surface 1223 can be a plane. The third surface 1223 and the intermediate connecting segment 113b are spaced apart, so as to avoid mutual interference between the third surface 1223 and the intermediate connecting segment 113b and thus avoid affecting the intermediate connecting segment 113b.

[0120] For example, the hardness of the shim 120 can range from 5 Shore A to 200 Shore A. Specifically, the hardness of the shim 120 can be 5 Shore A, 10 Shore A, 15 Shore A, 30 Shore A, 50 Shore A, 100 Shore A, 200 Shore A, or any value between 5 Shore A and 200 Shore A. This avoids the shim 120 having too low a hardness, resulting in poor support for the flexible screen 110, and also avoids the shim 120 having too high a hardness, resulting in excessive force on the bent portion 110b during bending. It is understood that the hardness range of at least one or more of the first shim 121, the second shim 122, and the third shim 123 can be between 5 Shore A and 200 Shore A. The hardness of any two of the first shim 121, the second shim 122, and the third shim 123 may be the same or different.

[0121] For example, the hardness of the first shim 121 can be less than or equal to the hardness of the second shim 122. This allows the first shim 121 to have a lower hardness, enabling it to deform under external force, thereby releasing and absorbing the external force and mitigating its impact on the bent portion 110b during and under bending conditions. Alternatively, the second shim 122 can have a higher hardness, providing better support for the bent portion 110b and helping to maintain and fix its bent state. At least one of the first shim 121 and the second shim 122 can be elastic, allowing it to return to its original shape after deformation, thus continuing to support and protect the bent portion 110b.

[0122] The third shim 123 provided in the embodiments of this application will be described below.

[0123] See Figure 1 and Figure 11 The second support portion 192's shim 120 may include a third shim 123, which may be located between the first display portion 110a and the bonding portion 110c. Specifically, the third shim 123 may be located between the first support portion 131 and the second support portion 132, and may be attached to both the first and second support portions 131 and 132, and also to the flexible screen 110 via the first and second support portions 131 and 132. For example, the third shim 123 may be attached to the first display portion 110a via the first support portion 131, and to the bonding portion 110c via the second support portion 132. The third shim 123 elevates the first and second support portions 131 and 132, thereby improving the support capability of the support portion 130 for the flexible screen 110.

[0124] In embodiments with a second raising member 122 and a third raising member 123, the third raising member 123 can be connected to the second raising member 122, thereby forming a single unit to provide continuous support for the support member 130. Alternatively, the third raising member 123 and the second raising member 122 can be spaced apart. In embodiments with a first raising member 121 and a third raising member 123, the first raising member 121 and the third raising member 123 can abut against each other or be spaced apart. In embodiments with a first raising member 121, a second raising member 122, and a third raising member 123, the second raising member 122 can be connected to or spaced apart from the third raising member 123, and the second raising member 122 can abut against or be spaced apart from the first raising member 121. This application does not limit the connection relationship between the raising members 120.

[0125] For example, the hardness of the third shim 123 can be greater than that of the second shim 122. On the one hand, the hardness of the second shim 122 can be set to be lower, which can reduce the force exerted by the second shim 122 on the bent portion 110b during the bending process. In addition, the second shim 122 can undergo smaller deformation to absorb and release the interaction force between the second shim 122 and the bent portion 110b, thereby reducing the impact on the bent portion 110b during the bonding process. On the other hand, the hardness of the third shim 123 can be set to be higher, thereby providing better support for at least a portion of the first display portion 110a and the bonding portion 110c.

[0126] Taking the connection between the second elevation member 122 and the third elevation member 123 as an example, the third elevation member 123 and the second elevation member 122 can be an integral structure, which simplifies the manufacturing process of the third elevation member 123 and the second elevation member 122 and makes the connection between the third elevation member 123 and the second elevation member 122 more stable. Alternatively, the third elevation member 123 and the second elevation member 122 can be manufactured separately. In the embodiment where the first surface 1221 is flat and the second surface 1222 is curved, the surface of the third elevation member 123 near the first display part 110a and the first surface 1221 can be located on the same plane, so that neither the second elevation member 122 nor the third elevation member 123 will affect the flatness of the light-emitting side of the flexible screen 110, thereby ensuring the display effect of the flexible screen 110. The surface of the third shim 123 away from the first display portion 110a and the second surface 1222 can transition smoothly, thereby avoiding stress concentration in the transition area between the two surfaces and preventing any impact on the transition area between the second end 112b of the bent portion 110b and the binding portion 110c. In the embodiment where the first surface 1221 is curved and the second surface 1222 is flat, the surface of the third shim 123 near the first display portion 110a and the first surface 1221 can transition smoothly, and the surface of the third shim 123 away from the first display portion 110a and the second surface 1222 can be located on the same plane. The principle of this has been explained and will not be repeated here. In the embodiment where the first surface 1221 and the second surface 1222 are curved, the surface of the third shim 123 near the first display portion 110a and the first surface 1221 can transition smoothly, and the surface of the third shim 123 away from the first display portion 110a and the second surface 1222 can transition smoothly. The principle of this has been explained and will not be repeated here.

[0127] It is understandable that the surface of the third shim 123 near the first display part 110a and the first surface 1221 may not be a smooth transition or located on the same plane, and the surface of the third shim 123 away from the first display part 110a and the second surface 1222 may not be a smooth transition or located on the same plane.

[0128] See Figure 12The curved portion 110b encloses and forms a receiving area 140. The support component 190 can be located in at least a portion of the receiving area 140, and the filler 151 can fill another portion of the receiving area 140. Taking the support component 190 located in a portion of the receiving area 140 as an example, the shim 120 can be accommodated in the partial receiving area 140, or the shim 120 can be accommodated in all of the receiving area 140. When the shim 120 is located in the partial receiving area 140, another portion of the receiving area 140 can be used to accommodate the filler 151 (e.g., filler adhesive) so that the receiving area 140 is filled with the shim 120 and the filler 151, thereby providing better support and protection for all parts of the curved portion 110b. For example, the accommodating region 140 may include a first region and a second region. The first region may be used to accommodate the shim 120, and the second region may be used to accommodate the filler 151. The second region may be used partially or entirely to accommodate the filler 151. For instance, the second region may also be used to accommodate the support member 130 or other structural components of the display module 10. Taking the second region accommodating the support member 130 as an example, when the support member 130 extends to the bend 110b, the second region may be used to accommodate a portion of the support member 130, and the filler 151 fills the remaining areas of the second region excluding the support member 130. Compared to filling the accommodating area 140 with the shim 120 and the support 130, filling the accommodating area 140 with the filler 151 allows for larger dimensional errors in the shim 120 and the support 130, improves the assemblability of the shim 120 and the support 130, and reduces the manufacturing difficulty of the shim 120 and the support 130. In addition, the filler 151 is easier to fill the accommodating area 140, which can reduce the manufacturing difficulty of the display module 10.

[0129] See Figure 1 The display module 10 may further include a reinforcing member 152, which may be located on at least one side of the raised member 120 along its thickness direction. For example, the reinforcing member 152 may be located on the side of the raised member 120 opposite to the first support member 131, i.e., the reinforcing member 152 may be located between the second support member 132 and the raised member 120. And / or, the reinforcing member 152 may be located between the first support member 131 and the raised member 120. The reinforcing member 152 can improve the mechanical strength of the display module 10. Exemplarily, the material of the reinforcing member 152 may be a metallic material such as copper, aluminum, or stainless steel, or other non-metallic materials.

[0130] See Figure 1The display module 10 may further include a cover plate 161, which is located on the light-emitting side of the first display unit 110a. The cover plate 161 protects the flexible screen 110 and prevents the user from scratching the flexible screen 110 when using it. For example, the orthographic projection of the first display unit 110a onto the plane of the cover plate 161 may be located within the cover plate 161, or the orthographic projections of both the first display unit 110a and the curved portion 110b onto the plane of the cover plate 161 may be located within the cover plate 161. That is, the area of ​​the cover plate 161 is larger than the area of ​​the flexible screen 110, which can provide better protection for the flexible screen 110.

[0131] The flexible screen 110 and the cover plate 161 can be connected by a connecting layer 162, for example, the connecting layer 162 can be formed of optically transparent adhesive. See also Figure 1 The connecting layer 162 may be located between the first display section 110a and the cover plate 161, or, see... Figure 9 The connecting layer 162 may be located between the first display portion 110a, the curved portion 110b and the cover plate 161.

[0132] See Figure 1The flexible screen 110 may include a screen body 112, and the first display portion 110a, the curved portion 110b, and the bonding portion 110c of the flexible screen 110 may all be provided with the screen body 112. The flexible screen 110 may also include a filter layer 113, which can be used to reduce the reflection of ambient light, thereby improving the display effect of the display module 10. The first display portion 110a may be provided with the filter layer 113, or the first display portion 110a and at least part of the curved portion 110b may be provided with the filter layer 113, or the first display portion 110a, the curved portion 110b, and the bonding portion 110c may all be provided with the filter layer 113. In some examples, the filter layer 113 may be located on the side of the screen body 112 facing the cover plate 161, and the filter layer 113 may be located between the connecting layer 162 and the screen body 112. For example, the filter layer 113 may be a polarizer. Alternatively, the filter layer 113 may include a color resist and a light-shielding material layer, with the color resist located in the light-emitting area and the light-shielding material layer located in the non-light-emitting area. The color resist can be used to filter light in the ambient light that is different from its own color. The light-shielding material layer can be formed of a material capable of blocking light and absorbing light that shines on it. The light-shielding material layer can have a relatively dark color (e.g., black). In other examples, the filter layer 113 can also be integrated into the screen body 112, for example, it can be integrated into the touch layer of the screen body 112. The implementation of the filter layer 113 is not limited in this application embodiment. In other examples, the filter layer 113 may not be provided. The flexible screen 110 may include a light-emitting area and a non-light-emitting area. The light-emitting area corresponds to a pixel. In addition, a non-light-emitting area is provided between adjacent light-emitting areas. The non-light-emitting area may surround the outer periphery of the light-emitting area and may correspond to at least a portion of the pixel defining layer.

[0133] See Figure 1 The flexible screen 110 may also include a protective layer 153 located on the light-emitting side of the bent portion 110b. The protective layer 153 can alleviate the stress on the various film layers in the flexible screen 110, for example, it can reduce the risk of metal trace layer breakage. The protective layer 153 may be located only in the bent portion 110b, or it may extend from the bent portion 110b to the first display portion 110a and / or the bonding portion 110c. Of course, the protective layer 153 may not be provided on the light-emitting side of the bent portion 110b.

[0134] The following describes the light adjustment element 171 provided in the embodiments of this application.

[0135] See Figure 2The curved portion 110b may include a curved display portion 114b. A light adjustment member 171 may be provided between the cover plate 161 and the curved display portion 114b. The light adjustment member 171 is attached to the flexible screen 110 and the cover plate 161, thereby excluding the air between the cover plate 161 and the curved display portion 114b and avoiding the influence of air on the light of the curved display portion 114b.

[0136] For example, the refractive index of the surface of the flexible screen 110 near the light modulator 171 can be equal to the refractive index of the light modulator 171. This surface is formed by the surface of a structural film layer in the flexible screen 110 near the light modulator 171, which can be a polarizer or a structural film layer in the screen body 112 near the light modulator 171. The refractive index of the light modulator 171 is the same as the refractive index of the structural film layer in the flexible screen 110 near the light modulator 171; that is, the refractive index of the light modulator 171 is the same as the refractive index of the surface of the flexible screen 110 near the light modulator 171. When light enters the light modulator 171 from the surface of the flexible screen 110 near the light modulator 171, the light can maintain its original angle and pass through the light modulator 171, allowing more than 90% of the light to penetrate the light modulator 171.

[0137] In some embodiments, a privacy layer 173 may be provided on the side of the light adjustment member 171 facing away from the curved display portion 114b, with the privacy layer 173 located on the side of the light adjustment member 171 facing the cover plate 161. In embodiments where the orthographic projections of the connecting layer 162 and the curved display portion 114b onto the plane of the cover plate 161 do not overlap, the privacy layer 173 may be located between the cover plate 161 and the light adjustment member 171. The light adjustment member 171 can be indirectly attached to the cover plate 161 via the privacy layer 173. In embodiments where the orthographic projection of the curved display portion 114b onto the plane of the cover plate 161 lies within the orthographic projection of the connecting layer 162 onto the plane of the cover plate 161, the privacy layer 173 may be located between the connecting layer 162 and the light adjustment member 171. The light adjustment member 171 can be indirectly attached to the cover plate 161 via the privacy layer 173 and the connecting layer 162.

[0138] For example, a light-shielding layer 172 may be provided on the side of the light adjustment member 171 away from the curved display portion 114b. The light-shielding layer 172 is opaque. The light-shielding layer 172 may be connected to the privacy layer 173, and the light-shielding layer 172 may extend along the thickness direction of the first display portion 110a.

[0139] For example, the privacy layer 173 and the light-shielding layer 172 may be connected at their adjacent ends to prevent light leakage. At least one of the privacy layer 173 and the light-shielding layer 172 may be formed on the light-adjusting member 171 by coating.

[0140] Among them, see Figure 2 The light emitted from the curved display unit 114b may include light ray G1, which can reach the privacy layer 173, and the direction of light ray G1 is deflected from the inside of the flexible screen 110 towards the edge (i.e., from the first display unit 110a towards the curved part 110b). Since the privacy layer 173 can block light from a wide viewing angle, light ray G1 cannot pass through the privacy layer 173, thereby achieving the purpose of preventing peeping. The light emitted from the curved display unit 114b may also include light ray G2, which can reach the light-shielding layer 172, and the direction of light ray G2 is deflected from the inside of the flexible screen 110 towards the edge. Since the light-shielding layer 172 is opaque, light ray G2 reaching the light-shielding layer 172 cannot pass through the light-shielding layer 172. Through the cooperation of the light-shielding layer 172 and the privacy layer 173, light rays G1 and G2 deflected from the inside of the flexible screen 110 towards the edge cannot be emitted from the light adjustment member 171 to reach outside the display module 10. The portion of light G1 that cannot pass through the privacy layer 173 and the portion of light G2 that cannot pass through the light-shielding layer 172 will be refracted and converged in the light adjustment member 171, and can form light G3. The direction of light G3 can be deflected from the edge of the flexible screen 110 to the inside (i.e. from the curved part 110b to the first display part 110a). Light G3 can pass through the privacy layer 173 and be emitted, thereby changing the direction of part of the light G1 and part of the light G2 from the inside to the edge of the flexible screen 110 to the inside of the edge of the flexible screen 110, so that the light can be emitted through the privacy layer 173, thereby achieving the effect of correcting the display distortion of the curved display part 114b.

[0141] In particular, some of the light emitted from the curved display unit 114b can be perpendicular to the first display unit 110a, or it can be biased inward from the edge of the flexible screen 110. This part of the light can be emitted directly through the privacy layer 173.

[0142] It is understandable that the metal trace layers in the flexible screen 110 are prone to breakage and damage. The screen body 112 may include a first metal trace layer, a second metal trace layer, a third metal trace layer, and a fourth metal trace layer stacked along the thickness direction. The first metal trace layer may include at least one of a first scan line, a second scan line, a third scan line, a first electrode of a capacitor structure, a light-emitting control line, and the gate of a plurality of thin-film transistors. The second metal trace layer may include at least one of a reference line and a second electrode of a capacitor structure. The third metal trace layer may include the source and drain electrodes of transistors. The fourth metal trace layer may include data lines. Taking the third and fourth metal trace layers as examples, these metal trace layers may be located on the side of the neutral layer of the screen body 112 near the cover plate 161, and these metal trace layers are subjected to tensile stress. By setting the shim 120 in this embodiment, the strain of the third metal trace layer (i.e., the relative deformation of the third metal trace layer under tensile stress) can be reduced by 2.23%, and the strain of the fourth metal trace layer can be reduced by 1.25%, thereby effectively improving the fracture problem of the metal trace layer. Furthermore, the stress conditions of each film layer within the flexible screen 110 can be obtained through mechanical simulation to infer its deformation. Then, by adjusting the position, shape, and other parameters of the first shim 121 and / or the second shim 122, the neutral layer is positioned as required, improving the stress of the metal trace layers within the screen 112.
