Description

Technical Field

[0001] This application belongs to the field of flexible display modules, specifically relating to a flexible display module and electronic device. Background Technology

[0002] With the development of technology, electronic devices are becoming increasingly widely used, and many of these devices are foldable. This means that an electronic device includes a first housing and a second housing that are movably connected. By placing a flexible display module on the first and second housings, forces are applied to the first and / or second housings, causing them to move away from or towards each other, thus enabling the electronic device to fold or unfold. During the folding process, the flexible display module is folded. However, in related technologies, the rebound force of the support backplate of the flexible display module is relatively large when it is folded, which may cause the electronic device to spring back after folding, making it difficult to maintain its folded state. Utility Model Content

[0003] The purpose of this application is to provide a flexible display module and an electronic device, at least to solve the problem that when the flexible display module is folded, the support back plate of the flexible display module has a large rebound force, which may cause the electronic device to spring back after being folded, making it difficult to maintain the folded state after the electronic device is folded.

[0004] In a first aspect, embodiments of this application provide a flexible display module, the flexible display module comprising: a display component and a supporting backplate;

[0005] The display component is stacked with the supporting back plate;

[0006] The support back plate has a bending area for bending the support back plate along a preset axis. A mesh area is provided in the bending area, and a mesh is provided in the mesh area. The mesh penetrates the support back plate where the bending area is located, and the extension direction of the mesh is perpendicular to the extension direction of the preset axis.

[0007] Secondly, embodiments of this application provide an electronic device, the electronic device including a device body and a flexible display module as described in any one of the first aspects above; the flexible display module is mounted on the device body.

[0008] In this embodiment, since the display component and the supporting backplate are stacked, the supporting backplate can support the display component, ensuring that the flexible display module can display normally after being applied to the electronic device. Because the supporting backplate has a bending area, when the flexible display module is applied to the electronic device, if the first or second housing of the electronic device is subjected to force and the electronic device is folded, the display component and the supporting backplate can be bent by the first or second housing. Thus, the supporting backplate can bend along a preset axis in the bending area, and the area of ​​the display component corresponding to the bending area will also bend. Since the mesh area has holes that penetrate the supporting backplate where the bending area is located, and the extension direction of the mesh is perpendicular to the extension direction of the preset axis, when the supporting backplate bends in the bending area, the mesh area will also bend. Simultaneously, the presence of the mesh reduces the rebound force of the supporting backplate and has little impact on the elastic modulus of the supporting backplate. In other words, in this embodiment of the application, by setting mesh holes in the mesh area, the mesh holes penetrate the support back plate where the bending area is located, and the extension direction of the mesh holes is perpendicular to the extension direction of the preset axis line, the rebound force of the support back plate in the bending area is reduced, so that when the flexible display module is applied in electronic devices, the electronic devices can maintain the folded state better after folding, avoiding the problem of possible rebound after the electronic devices are folded.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Before explaining the flexible display module provided in the embodiments of this application, the application scenarios of the flexible display module provided in the embodiments of this application will be specifically described: In related technologies, a flexible display module includes a display component and a supporting backplate. The display component and the supporting backplate are stacked. The flexible display module has a bending area, and the flexible display module can be bent in this bending area. That is, when the flexible display module is applied to an electronic device, the bending area of ​​the flexible display module can be bent when the electronic device is folded. When the bending area of ​​the flexible display module bends, the supporting backplate also bends, that is, the part of the supporting backplate corresponding to the bending area also bends. However, when the supporting backplate bends, the supporting backplate has a large rebound force. That is, once the supporting backplate is bent, the bending point of the supporting backplate has a rebound force, so the supporting backplate tends to drive the flexible display module to unfold, which may make it difficult for the electronic device to maintain its folded state after being folded. In addition, when flexible display modules are applied to electronic devices, the first and second housings in the electronic device are connected by a hinge assembly. The rebound force of the supporting back plate is relatively large. In order for the hinge assembly to be able to ensure that the electronic device remains folded after being folded, the design of the hinge assembly is more complex, which increases the design difficulty of the hinge assembly.

[0025] like Figures 1 to 10 As shown, the flexible display module includes a display component 10 and a support backplate 20.

[0026] The display component 10 and the support back plate 20 are stacked together. The support back plate 20 has a bending region 201 for bending the support back plate 20 along a preset axis. A mesh region 2011 is provided in the bending region 201, and a mesh 2012 is provided in the mesh region 2011. The mesh 2012 penetrates the support back plate 20 where the bending region 201 is located, and the extension direction of the mesh 2012 is perpendicular to the extension direction of the preset axis.

[0027] In this embodiment, since the display component 10 and the support back plate 20 are stacked, the support back plate 20 can support the display component 10, ensuring that the flexible display module can display normally after being applied to the electronic device. Because the support back plate 20 has a bending area 201, when the flexible display module is applied to the electronic device, once the first or second housing of the electronic device is subjected to force, causing the electronic device to be folded, the display component 10 and the support back plate 20 can be bent by the first or second housing. Thus, the support back plate 20 can be bent along a preset axis in the bending area 201, and the area of ​​the display component 10 corresponding to the bending area 201 will also be bent. Because the mesh area 2011 contains mesh holes 2012 that penetrate the support back plate 20 where the bending area 201 is located, and the extension direction of the mesh holes 2012 is perpendicular to the extension direction of the preset axis, when the support back plate 20 bends in the bending area 201, the mesh area 2011 will also bend. Simultaneously, the presence of the mesh holes 2012 reduces the rebound force of the support back plate 20 and has little impact on the elastic modulus of the support back plate 20. In other words, in this embodiment, by providing mesh holes 2012 in the mesh area 2011, penetrating the support back plate 20 where the bending area 201 is located, and extending the mesh holes 2012 perpendicular to the extension direction of the preset axis, the rebound force of the support back plate 20 in the bending area 201 is reduced. This allows the flexible display module to maintain its folded state better after folding when applied to electronic devices, avoiding potential springback issues after folding.

[0028] In some embodiments, the support back plate 20 has a groove 21 on the surface opposite to the display component 10, and the area where the groove 21 is located forms a bending region 201. By setting the groove 21 to form the bending region 201, the thickness of the bending region 201 is less than the thickness of other areas of the support back plate 20 except for the bending region 201. This can further reduce the rebound force of the bending region 201, so that when the flexible display module is applied in an electronic device, the electronic device can be further ensured to remain in a folded state after folding, avoiding the problem of possible rebound after the electronic device is folded.

[0029] What is needed is that when the support back plate 20 is separated from the surface of the display component 10, a groove 21 is provided, and the groove 21 forms a bending area 201, which is equivalent to making the support back plate 20 a support back plate 20 with unequal thickness.

[0030] It should also be noted that, in this embodiment, a groove 21 can be formed on the surface of the support back plate 20 away from the display component 10 using laser engraving. Alternatively, other processes can be used to form the groove 21 on the surface of the support back plate 20 away from the display component 10, such as etching. The specific process for setting the groove 21 on the support back plate 20 is not limited in this embodiment.

[0031] In addition, after the groove 21 is provided on the surface of the support back plate 20 away from the display component 10, the area where the groove 21 is located is the bending area 201. At this time, the thickness of the bending area 201 is the distance between the surface of the support back plate 20 facing the display component 10 and the bottom of the groove 21.

[0032] Furthermore, in related technologies, the support back plate 20 is designed with uniform thickness, meaning that the thickness of any area on the support back plate 20 is equal to the thickness of other areas. As a result, when the support back plate 20 is bent, the rebound force of the area on the support back plate 20 corresponding to the bending area 201 of the display component 10 is relatively large. However, in this embodiment, by setting the thickness of the bending area 201 of the support back plate 20 to be less than the thickness of other areas, it is equivalent to reducing the thickness of the bending area 201 on the support back plate 20. This results in an unequal thickness of the support back plate 20, and when the support back plate 20 is bent, the area with the smaller thickness bends, thereby reducing the rebound force of the support back plate 20.

[0033] In addition, in this embodiment, the support back plate 20 also has a first region 202 and a second region 203; the first region 202, the bending region 201, and the second region 203 are sequentially distributed along a direction perpendicular to a preset axis. That is, the bending region 201 is located between the first region 202 and the second region 203. The bending region 201 corresponds to the bendable portion 101 of the display component 10, the first region 202 is opposite to the region on the first side of the bendable portion 101 of the display component 10, and the second region 203 is opposite to the region on the second side of the bendable portion 101 of the display component 10. In this embodiment, when the flexible display module is applied in an electronic device, the electronic device may include a first housing and a second housing, which are connected by a hinge assembly. The flexible display module is connected to the first housing and the second housing respectively, so that the bendable portion 101 of the display component 10 is opposite to the hinge assembly, the area on the first side of the bendable portion 101 corresponds to the position of the first housing, the area on the second side of the bendable portion 101 corresponds to the position of the second housing, the first area 202 of the support back plate 20 corresponds to the position of the first housing, the second area 203 of the support back plate 20 corresponds to the position of the second housing, and the bending area 201 of the support back plate 20 corresponds to the position of the hinge assembly.

[0034] Additionally, in the embodiments of this application, such as Figure 1 As shown, the display component 10 includes a cover layer 11, a display layer 12, and a display support layer 13. The cover layer 11, the display layer 12, and the display support layer 13 are stacked sequentially, that is, the display layer 12 is located between the cover layer 11 and the display support layer 13, and a support back plate 20 is provided on the side of the display support layer 13 away from the display layer 12.

[0035] In addition, in this embodiment, the support back plate 20 can be made of carbon fiber, that is, the support back plate 20 is formed of carbon fiber, so that the support back plate 20 has sufficient toughness. Of course, the support back plate 20 can also be made of other materials, as long as the support back plate 20 can be bent. The specific material of the support back plate 20 is not limited in this embodiment.

[0036] Furthermore, in this embodiment, the thickness of the first region 202 and the thickness of the second region 203 of the supporting back plate 20 can be set according to actual needs, and the thickness of the bending region 201 can also be set according to actual needs, as long as the thickness of the bending region 201 is less than the thickness of the second region 203 and less than the thickness of the first region 202. Wherein, the thickness of the first region 202 is equal to the thickness of the second region 203.

[0037] In some embodiments, the thickness of the second region 203 can be in the range of 80-150 μm, that is, the thickness of the second region 203 can be any value within 80-150 μm. For example, the thickness of the second region 203 is 80 μm, 90 μm, 100 μm, 120 μm, 135 μm, or 150 μm. The specific value of the thickness of the second region 203 is not limited in this embodiment. Furthermore, the thickness of the bending region 201 can range from 30 to 80 μm, meaning it can be any value between 30 and 80 μm. For example, the thickness of the bending region 201 could be 30 μm, 40 μm, 45 μm, 60 μm, 70 μm, or 80 μm. The specific value of the thickness of the second region 203 is not limited in this embodiment.

[0038] Furthermore, in this embodiment, the thickness of the bending region 201 can be made smaller. In this case, it is not necessary to provide mesh 2012 in the bending region 201. For example, when the thickness of the bending region 201 is less than or equal to 45 μm, it is not necessary to provide mesh 2012 in the bending region 201. This also improves the impact resistance of the bending region 201, making the display component 10 less prone to mold marks. Here, mold marks refer to irregular patterns, traces, or imprints that appear on or inside the surface of the display component 10.

[0039] In addition, in some embodiments, the mesh 2012 may include a plurality of first meshes 2015, some of which are located on the first side of the bending region 201 and others are located on the second side of the bending region 202. The first side and the second side are arranged adjacent to each other along a direction perpendicular to a preset axis. The first meshes 2015 located on the first side and the first meshes 2015 located on the second side are all distributed at intervals along the preset axis, and the extension direction of the first meshes 2015 is perpendicular to the extension direction of the preset axis.

[0040] When the display component 10 is bent, that is, when the bending area 201 is bent, by setting some of the first mesh holes 2015 on the first side of the bending area 201 and others on the second side of the bending area 202, the first mesh holes 2015 on the first side and the first mesh holes 2015 on the second side are all distributed at intervals along a preset axis. The extension direction of the first mesh holes 2015 is perpendicular to the extension direction of the preset axis. This can effectively reduce the rebound force of the bending area 201 and have little impact on the elastic modulus of the bending area 201. It can also prevent the display component 10 from having obvious mold marks when it is bent, thereby improving the display effect of the display component 10.

[0041] In addition, in some embodiments, the mesh 2012 further includes a plurality of second meshes 2016, which are alternately distributed with the first meshes 2015 along the extension direction of a preset axis; the extension direction of the second meshes 2016 is perpendicular to the extension direction of the preset axis, and the second meshes extend from the first side to the second side in a direction perpendicular to the preset axis. With this arrangement, when the display component 10 is bent, that is, when the bending area 201 is bent, the plurality of second meshes 2016 can further reduce the rebound force of the bending area 201, effectively ensuring that the electronic device remains in a folded state and avoiding the problem of possible rebound after the electronic device is folded.

[0042] In some embodiments, the second mesh 2016 is symmetrical about a preset axis, and the first mesh 2015 on the first side and the first mesh 2015 on the second side are symmetrically arranged about the preset axis along an extension direction perpendicular to the preset axis. This arrangement is equivalent to both the first mesh 2015 and the second mesh 2016 being symmetrical about the preset axis. This allows the first mesh 2015 and the second mesh 2016 to minimize the rebound force of the bending region 201 while maintaining a relatively low elastic modulus, effectively ensuring the electronic device remains folded and preventing potential springback after folding.

[0043] In some embodiments, the length of the second mesh 2016 extending from the preset centerline to one end is less than the length of the first mesh 2015; in other embodiments, the length of the second mesh 2016 extending from the preset centerline to one end is greater than the length of the first mesh 2015. Specific settings can be configured as needed.

[0044] In some embodiments, the mesh 2012 may further include multiple third meshes 2017. Some of the third meshes 2017 are located on the side of the first mesh 2015 on the first side that is away from the preset axis, and other third meshes 2017 are located on the side of the first mesh 2015 on the second side that is away from the preset axis. The third meshes 2017 are spaced apart along the extension direction of the preset axis, and the distance between two adjacent third meshes 2017 is greater than the distance between two adjacent first meshes 2015 along the extension direction of the preset axis. The extension direction of the third meshes 2017 is perpendicular to the extension direction of the preset axis. With this arrangement, when the display component 10 is bent, that is, when the bending area 201 is bent, the multiple third meshes 2017 can further reduce the rebound force of the bending area 201, effectively ensuring that the electronic device remains in a folded state and avoiding the problem of possible rebound after the electronic device is folded.

[0045] It should be noted that, in this embodiment of the application, the bending area 201 may be provided with a first mesh 2015, a second mesh 2016 and a third mesh 2017 at the same time. In this case, the rebound force of the bending area 201 can be further reduced, so that the bending area 201 is not easy to spring back after being bent. Thus, after the flexible display module is applied to the electronic device, it can effectively ensure that the electronic device remains in a folded state and avoid the problem of springback that may occur after the electronic device is folded.

[0046] In addition, in some embodiments, the width of the bending region 201 is greater than or equal to the width of the bending portion 101. The width of the bending region 201 is the distance between the two opposite sides of the bending region 201 along the direction from the first region 202 to the second region 203. The width of the bending portion 101 is the distance between the two opposite sides of the bending region 201 along the direction from the first region 202 to the second region 203.

[0047] By setting the width of the first region 202 to be greater than or equal to the width of the bending region 201, when the display component 10 is bent, it can be ensured that the bending regions 201 on the support back plate 20 are all thinned. This ensures that when the display component 10 is bent, the bending range of the area corresponding to the bending region 201 on the support back plate 20 can effectively cover the bending range of the bent portion 101 of the display component 10, thereby effectively reducing the rebound force generated when the support back plate 20 is bent. In other words, by setting the width of the bending region 201 to be greater than or equal to the width of the bent portion 101, the rebound force of the support back plate 20 can be effectively reduced when the display component 10 is bent.

[0048] For example, such as Figure 8 As shown, when the display component 10 is bent, the bent portion forms a teardrop shape, and the bending area 201 can cover the entire teardrop shape formed by the bending of the display component 10.

[0049] Of course, in this embodiment, the width of the bending region 201 is greater than or equal to the width of the bending portion 101, for example, as Figure 7 As shown, when the display component 10 is bent, the bent portion 101 forms a teardrop shape, and the bending area 201 can be positioned corresponding to the maximum bending diameter of the teardrop shape.

[0050] In addition, in some embodiments, the width of the mesh area 2011 is equal to the width of the bending area 201. The width of the mesh area 2011 is the distance between the two opposite sides of the mesh area 2011 along the direction from the first area 202 to the second area 203. The width of the bending area 201 is the distance between the two opposite sides of the bending area 201 along the direction from the first area 202 to the second area 203.

[0051] By setting the width of the mesh area 2011 to be equal to the width of the bending area 201, it can be ensured that the bending area 201 is provided with mesh 2012. Therefore, when the display component 10 is bent, the range of the mesh 2012 in the area corresponding to the bending area 201 on the support back plate 20 can effectively cover the bending range of the bent portion 101 of the display component 10, thereby effectively reducing the rebound force generated when the support back plate 20 is bent. In other words, by setting the width of the mesh area 2011 to be equal to the width of the bending area 201, the rebound force of the support back plate 20 can be effectively reduced when the display component 10 is bent.

[0052] It should be noted that the width of the mesh area 2011 can also be smaller than the width of the bending area 201. Specifically, the width of the mesh area 2011 only needs to be close to the width of the bending area 201 to ensure that the rebound force when the support back plate 20 is bent is reduced.

[0053] In some embodiments, the support backplate 20 may also have a first region 202 and a second region 203; the first region 202, the bending region 201, and the second region 203 are sequentially distributed along a direction perpendicular to a preset axis; an adhesive layer 001 is provided between the support backplate 20 and the display component 10. With this arrangement, the adhesive layer 001 can effectively bond the display component 10 to the support backplate 20, ensuring that the support backplate 20 supports the display component 10.

[0054] In some embodiments, the adhesive layer 001 has a first non-adhesive region 2018 and a second non-adhesive region 2021. The first non-adhesive region 2018 is at least partially corresponding to the bending region 201, and the remaining portion of the first non-adhesive region 2018 is corresponding to the first region 2027. The second non-adhesive region 2021 is at least partially corresponding to the bending region 201, and the remaining portion of the second non-adhesive region 2021 is corresponding to the second region 203. The first non-adhesive region 2018 and the second non-adhesive region 2021 are distributed at intervals, and both the first non-adhesive region 2018 and the second non-adhesive region 2021 extend along the extension direction of a preset axis.

[0055] The thickness of the bending area 201 of the support back plate 20 is not equal to the thickness of the first area 202 and the second area 203. Therefore, during the manufacturing of the support back plate 20, due to manufacturing processes and other reasons, a noticeable boundary line can easily appear in the thickness transition area of ​​the support back plate 20. Once the support back plate 20 is bonded to the display component 10 using the adhesive layer 001, the boundary line on the support back plate 20 will be transmitted to the display component 10 through the pressure, potentially causing mold marks on the surface of the display component 10 and affecting its display effect. However, in this embodiment, by providing a first non-adhesive area 2018 and a second non-adhesive area 2021, the boundary line of the thickness transition area of ​​the support back plate 20 is prevented from being transmitted to the display component 10 through the pressure. That is, the boundary line of the thickness transition area of ​​the support back plate 20 will not contact the adhesive layer 001, thus preventing the transmission of mold marks to the display component 10 and effectively improving its display effect.

[0056] It should be noted that, in this embodiment, the adhesive layer 001 can be provided with a first groove on the surface away from the display component 10, and the area where the first groove is located forms a first non-adhesive area 2018, that is, the adhesive layer 001 is not bonded to the support back plate 20 at the first non-adhesive area 2018; of course, a first through groove can also be provided on the adhesive layer 001, the first through groove penetrates the adhesive layer 001, the first through groove extends along the extension direction of a preset axis line, and the area where the first through groove is located forms a first non-adhesive area 2018, that is, the adhesive layer 001 is not bonded to either the support back plate 20 or the display component 10 at the first non-adhesive area 2018. Similarly, a second groove can be provided on the surface of the adhesive layer 001 away from the display component 10. The area where the second groove is located forms a second non-adhesive area 2021, that is, the adhesive layer 001 is not bonded to the support back plate 20 at the second non-adhesive area 2021. Of course, a second through groove can also be provided on the adhesive layer 001. The second through groove extends through the adhesive layer 001 and extends along the extension direction of the preset axis. The area where the second through groove is located forms a second non-adhesive area 2021, that is, the adhesive layer 001 is not bonded to either the support back plate 20 or the display component 10 at the second non-adhesive area 2021.

[0057] Additionally, in some embodiments, such as Figure 6 As shown, the sum of the width of the first non-adhesive area 2018 and the width of the second non-adhesive area 2021 is L, satisfying: 1mm≤L≤2mm. With this setting, while ensuring a firm bond between the support backplate 20 and the display component 10, the molding marks in the thickness transition area of ​​the support backplate 20 will not be transferred to the display component 10, thereby reducing the probability of molding marks appearing on the display component 10 and effectively improving the display effect of the display component 10.

[0058] It should be noted that L can be any value between 1mm and 2mm. For example, L can be 1mm, 1.2mm, 1.5mm, 1.8mm, or 2mm. The specific value of L is not limited in the embodiments of this application.

[0059] In addition, in some embodiments, the adhesive layer may have a third non-adhesive region 2022, which covers the bending region 201, and a portion of the third non-adhesive region 2022 is provided corresponding to the first region 202, and a portion of the third non-adhesive region 2022 is provided corresponding to the second region 203; wherein, the third non-adhesive region 2022 extends along the extension direction of a preset axis.

[0060] With this setup, the bending area 201 will not be bonded to the display component 10 via the adhesive layer 001, and a portion of the third non-adhesive area 2022 in the first area 203 and the third non-adhesive area 2022 in the second area 203 will not be bonded to the display component 10 via the adhesive layer 001. This reduces the probability of mold marks appearing on the display component 10, saves on the amount of adhesive layer 001, and lowers costs.

[0061] It should be noted that, in this embodiment, a third groove may be provided on the surface of the adhesive layer 001 facing away from the display component 10. The area where the third groove is located forms a third non-adhesive area 2022, that is, the adhesive layer 001 is not bonded to the support back plate 20 at the third non-adhesive area 2022. Of course, a third through groove may also be provided on the adhesive layer 001. The third through groove extends through the adhesive layer 001 and extends along the extension direction of the preset axis. The area where the third through groove is located forms a third non-adhesive area 2022, that is, the adhesive layer 001 is not bonded to either the support back plate 20 or the display component 10 at the third non-adhesive area 2022.

[0062] In this embodiment, since the display component 10 and the support back plate 20 are stacked, the support back plate 20 can support the display component 10, ensuring that the flexible display module can display normally after being applied to the electronic device. Because the support back plate 20 has a bending area 201, when the flexible display module is applied to the electronic device, once the first or second housing of the electronic device is subjected to force, causing the electronic device to be folded, the display component 10 and the support back plate 20 can be bent by the first or second housing. Thus, the support back plate 20 can be bent along a preset axis in the bending area 201, and the area of ​​the display component 10 corresponding to the bending area 201 will also be bent. Because the mesh area 2011 contains mesh holes 2012 that penetrate the support back plate 20 where the bending area 201 is located, and the extension direction of the mesh holes 2012 is perpendicular to the extension direction of the preset axis, when the support back plate 20 bends in the bending area 201, the mesh area 2011 will also bend. Simultaneously, the presence of the mesh holes 2012 reduces the rebound force of the support back plate 20 and has little impact on the elastic modulus of the support back plate 20. In other words, in this embodiment, by providing mesh holes 2012 in the mesh area 2011, penetrating the support back plate 20 where the bending area 201 is located, and extending the mesh holes 2012 perpendicular to the extension direction of the preset axis, the rebound force of the support back plate 20 in the bending area 201 is reduced. This allows the flexible display module to maintain its folded state better after folding when applied to electronic devices, avoiding potential springback issues after folding.
