In the flexible display screen module 100 and the mobile terminal 200 of the embodiment of the present application, the glue layer 20 and the flexible display screen 10 are stacked, the elastic layer 30 and the glue layer 20 are stacked, the elastic layer 30 is fixedly connected with the flexible display screen 10 through the glue layer 20, the supporting assembly 40 includes a plurality of supporting bars 41, the plurality of supporting bars 41 are uniformly arranged on the elastic layer 30 at intervals, and the elastic layer 30 at least partially covers the plurality of supporting bars 41. So, when flexible display screen 10 buckles, 41 atress extrudees of support bar, elastic layer 30 can provide cushioning effect for support bar 41, can avoid support bar 41 the phenomenon of extrusion gathering to appear, simultaneously, elastic layer 30 can exert the bounce so that make support bar 41 resume to evenly distributed state for support bar 41 when resumeing, avoid flexible display screen 10 openly to appear phenomenons such as obvious impression and unevenness, guarantee flexible display screen 10's roughness.
It can be understood that, in the embodiment of the present application, the flexible display screen module 100 has a property of being soft and capable of being bent, or the material composing the flexible display screen module 100 is soft and capable of being bent, so that the flexible display screen module 100 can cooperate with the shell assembly 300 to realize the change of the display area of the flexible display screen 10. Specifically, second shell 302 may slide relative to first shell 301 to bring extension 12 at least partially out of shell assembly 300 or back into shell assembly 300.
Referring to fig. 1 and fig. 2, a mobile terminal 200 according to an embodiment of the present invention may include two forms. The first configuration is a configuration (as shown in fig. 1) in which the first casing 301 and the second casing 302 are fitted together, that is, the configuration in which the mobile terminal 200 is located when the first casing 301 and the second casing 302 are close to each other and move to the extreme position, in which the flat portion 11 of the flexible display screen 10 is exposed outside the casing assembly 300, the expanded portion 12 is substantially completely hidden inside the casing assembly 300, and the display area of the mobile terminal 200 is small, which is convenient for carrying. The second configuration is a configuration in which the second shell 302 moves away from the first shell 301 to drive the extension portion 12 of the flexible display screen 10 to gradually extend out of the shell assembly 300 (see fig. 2), and in the second configuration, the extension portion 12 of the flexible display screen 10 at least partially extends out of the shell assembly 300 to form a display portion of the mobile terminal 200 together with the flat portion 11, so that the display area of the mobile terminal 200 is larger to provide a better display effect for a user.
In the embodiment of the present application, the "display area" refers to an area of a portion of the flexible display screen 10 exposed outside the case assembly 300 for display.
In the embodiment of the present application, the fact that the extension portion 12 can be hidden in the case assembly 300 is understood that the extension portion 12 can be housed in the internal space of the case assembly 300 and is not exposed, or the fact that the extension portion 12 can be hidden on the back surface of the case assembly 300 and is exposed from the back surface is described herein by taking as an example the case where the extension portion 12 can be housed in the internal space of the case assembly 300 and is not exposed.
Specifically, in the illustrated embodiment, the first housing 301 is slidably connected to the second housing 302, and the extension portion 12 of the flexible display 10 can be disposed inside the housing assembly 300 in a hidden configuration. Referring to fig. 1, in the first mode, the extension portion 12 of the flexible display screen 10 is not used for display, and only the flat portion 11 is used for display. When the second shell 302 moves away from the first shell 301, the flexible display 10 can be moved, so that the extension portion 12 of the flexible display 10 is at least partially pulled out of the shell assembly 300 to switch to the second configuration. In the second configuration, the extension portion 12 is at least partially pulled out of the housing assembly 300, and the flat portion 11 and the extension portion 12 are simultaneously used for display, thereby changing the display area of the mobile terminal 200.
Referring to fig. 3 and 4, in some embodiments, the mobile terminal 200 further includes a guide shaft 201, the guide shaft 201 is disposed on the second housing 302, a middle portion of the expansion portion 12 is bent and wound on the guide shaft 201 relative to the flat portion 11, and the guide shaft 201 abuts against the supporting bar 41.
Thus, the guide shaft 201 abuts against the support bars 41 of the flexible display screen module 100 to support the whole flexible display screen module 100, meanwhile, the guide shaft 201 can also assist the flexible display screen 10 to bend, and the guide shaft 201 rotates to enable the extension portion 12 to bend around the guide shaft 201, so that the extension portion 12 at least partially extends out of the shell assembly 300 or retracts into the shell assembly 300. The supporting bars 41 can bear the pressure from the direction of the guide shaft 201 and the flexible display module 100, and the supporting bars 41 can also be bent around the guide shaft 201 to ensure the flexible display module 100 to move along with the shell assembly 300.
Further, referring to fig. 3, in some embodiments, the mobile terminal 200 further includes a tensioning mechanism 202, the tensioning mechanism 202 is installed in the first housing 301 and connected to an end of the extension portion 12 away from the flat portion 11, and the tensioning mechanism 202 is used for tensioning the flexible display screen 10.
Thus, in the process that the second shell 302 drives the extension portion 12 to be unfolded out of the shell assembly 300 or retracted into the shell assembly 300, the tensioning mechanism 202 can tension the flexible display screen module 100, and the tensioning mechanism 202 is matched with the guide shaft 201, so that the extension portion 12 is not arched or folded to ensure that the extension portion 12 can be smoothly unfolded or retracted.
Specifically, the tensioning mechanism 202 includes a rope 2021 and a pulley 2022, the pulley 2022 is disposed on the second shell 302 and can move relative to the first shell 301 along with the second shell 302, one end of the rope 2021 is fixedly connected to the end of the expansion portion 12, and the other end is wound around the pulley 2022. In one example, as the second housing 302 moves away from the first housing 301, the pulley 2022 gradually releases the pulling rope 2021, thereby gradually releasing the expansion portion 12, the expansion portion 12 gradually expands to the outside of the housing assembly 300 in cooperation with the rolling of the rotation shaft, the distance of movement of the pulley 2022 is the same as the stroke distance of the expansion portion 12, and in this case, the expansion portion 12 expands outward with respect to the first housing 301 at twice the speed of the pulley 2022 with respect to the first housing 301. Meanwhile, in the process that the expansion part 12 is gradually unfolded out of the shell assembly 300, the pulley 2022 can tension the pull rope 2021, thereby realizing the tension of the flexible display screen 10.
In another example, during the process that the second shell 302 is relatively close to the first shell 301, the pulley 2022 moves along with the second shell 302, one end of the rope 2021 is fixedly connected with the expansion portion 12, the other end of the rope 2021 is fixedly connected with the first shell 301, the expansion portion 12 is gradually retracted into the shell assembly 300 by matching with the rolling of the rotating shaft, the pulley 2022 drives the rope 2021 to move towards the side where the first shell 301 is located so as to drive the expansion portion 12 to be gradually retracted into the shell assembly 300, and the pulley 2022 gradually retracts the rope 2021, in such a case, the expansion portion 12 is retracted inwards relative to the first shell 301 at a speed twice as that of the pulley 2022 relative to the first shell 301. Meanwhile, the pulley 2022 can tension the pull rope 2021 during the process of retracting and unfolding the expansion part 12 to the shell assembly 300, thereby realizing the tension of the flexible display screen 10. It is understood that during the assembly process of the mobile terminal 200, one end of the pulling rope 2021 may be sequentially wound around the pulley 2022 and then fixedly connected to the first housing 301, and during the installation process, it is required to ensure that the flexible display screen 10 is in a tensioned state, so that the tensioning mechanism 202 can tension the flexible display screen 10 no matter how the second housing 302 moves due to the presence of the tensioning mechanism 202.
It is understood that during the process of pulling the rope 2021 and the expanding portion 12 of the guide shaft 201 from two directions, the guide shaft 201 can support the bottom of the flexible display module 100, i.e. the guide shaft 201 will apply a force to the flexible display module 100 in a direction away from the pulley 2022.
In the related art, in the motion process of the flexible display screen module, the heat generated by friction enables the viscosity and the elastic modulus of the adhesive layer to be reduced, and the supporting bars are displaced due to the rotation of the guide shaft, so that the supporting bars are gathered. And the unable even support flexible display screen module of support bar of gathering for obvious dent and arch appear in the display surface of flexible display screen, and the planarization descends, causes the damage of flexible display screen module even.
In the present embodiment, the elastic layer 30 is added between the glue layer 20 and the support strip 41, so that the elastic layer 30 is stacked on the glue layer 20 and can cover the support strip 41. Elastic layer 30 has better elastic modulus and high temperature resistance characteristic for elastic layer 30 has the effect of buffering, can absorb the pressure that comes from support bar 41, and relies on self elasticity to promote different support bars 41 and resume the normal position, avoids support bar 41 to produce the problem of gathering, and then has guaranteed the planarization of flexible display screen 10, has improved the life-span of flexible display screen module 100.
In the present embodiment, the elastic layer 30 covers the supporting bars 41, that is, the supporting bars 41 are partially or completely nested in the elastic layer 30, or the supporting bars 41 are sandwiched between different supporting bars 41 through the material of the elastic layer 30, so that the elastic layer 30 can fix the positions of the supporting bars 41 and ensure that the different supporting bars 41 can be uniformly spaced.
Referring to fig. 3 and 4, in some embodiments, the flexible display screen 10 includes a flat portion 11 and an extended portion 12 connected to each other, the extended portion 12 can be bent with respect to the flat portion 11, and the elastic layer 30 is disposed on the extended portion 12.
In this way, the extension portion 12 is bent around the guide shaft 201, the elastic layer 30 is disposed on the extension portion 12, so that the supporting strip 41 can be formed between the extension portion 12 and the guide shaft 201, and further, the supporting strip 41 can support the extension portion 12 in the elastic layer 30, the elastic layer 30 can absorb the pressure between the supporting strips 41, and the flexible display screen 10 is prevented from being uneven and damaged due to the aggregation of the supporting strips 41.
Specifically, the first shell 301 is slidably connected to the second shell 302, so that the expansion portion 12 is disposed inside the shell assembly 300 in a bending manner, and belongs to a hidden structure. In the first configuration, the extension 12 passes around the guide shaft 201 and back inside the housing assembly 300, the extension 12 is not used for display, and only the flat portion 11 is used for display. When the second housing 302 moves away from the first housing 301, the flexible display module 100 is driven to move, the expansion portion 12 is at least partially pulled out of the housing assembly 300, the pull rope 2021 and the guide shaft 201 can pull the flexible display 10, and the elastic layer 30 and the supporting bar 41 can bear the pressure of the guide shaft 201 on the expansion portion 12, so as to convert to the second configuration. In the second configuration, the extension portion 12 is at least partially pulled out of the housing assembly 300, and the flat portion 11 and the extension portion 12 are simultaneously used for display, thereby changing the display area of the mobile terminal 200.
The mobile terminal 200 in the embodiment of the present application may be an electronic device such as a smart phone or a tablet computer, or may be a device that can be equipped with a display device such as a game device, a vehicle-mounted computer, a notebook computer, or a video player, and is not specifically shown here.
In addition, in the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present application, "a plurality" means two or more unless specifically defined otherwise.
It should be noted that in the description of the present application, it is to be understood that the terms "central", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner" and "outer" indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present application. In addition, it should be noted that, in the description of the present application, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be interpreted broadly, e.g., as either a fixed connection, a detachable connection, or an integral connection; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
In the embodiment of the present application, the material of the supporting bar 41 is not limited, and the supporting bar 41 may be made of a metal material such as steel or a plastic material, which meets the requirement. Meanwhile, the materials of the different supporting strips 41 may be the same, different, partially the same or partially different, and are not limited herein.
In certain embodiments, the elastic modulus of the elastic layer 30 is greater than the elastic modulus of the glue layer 20. The elastic layer 30 may be made of at least one of thermoplastic polyurethane elastomer rubber, polyamide resin, and acryl, and the adhesive layer 20 may be a pressure sensitive adhesive tape.
So, elastic layer 30 can be made by at least one of thermoplastic polyurethane elastomer rubber, polyamide resin and ya keli for elastic modulus of elastic layer 30 is greater than the elastic modulus of glue film 20, and the effect of absorbing the pressure of support bar 41 is better, can also make support bar 41 resume normal position simultaneously, avoids the gathering of support bar 41.
Specifically, the thermoplastic polyurethane elastomer rubber, the polyamide resin, and the acryl have a good elastic modulus to absorb the pressure of the supporting strip 41. In the manufacturing process, the thermoplastic polyurethane elastomer rubber, the polyamide resin and the acrylic resin can be converted from colloid solidification to an elastic solid state, so that the elastic layer 30 is matched with the supporting strip 41 and the manufacturing is simple and convenient.
It is understood that in other embodiments, the elastic layer 30 can be made of an elastic material, and only a sufficient elastic modulus and strength are required, and the specific material of the elastic layer 30 is not limited in the embodiments of the present application.
Referring to fig. 5 and 6, in some embodiments, the end of the supporting strip 41 away from the glue layer 20 protrudes from the elastic layer 30.
Thus, the supporting bar 41 protrudes from the elastic layer 30, so that the guiding shaft 201 can be abutted and made into the supporting bar 41, and further the guiding shaft 201 supports the flexible display screen module 100 through the supporting bar 41, thereby preventing the elastic layer 30 from directly contacting with the guiding shaft 201, and causing the guiding shaft 201 to wear the elastic layer 30.
Specifically, when the elastic layer 30 covers the supporting bar 41, one end of the supporting bar 41, which is far away from the adhesive layer 20, protrudes out of the elastic layer 30, so that the guide shaft 201 directly contacts the supporting bar 41, and the guide shaft 201 is prevented from contacting the elastic layer 30. The end of the supporting strip 41 near the glue layer 20 can be directly connected with the glue layer 20, or can be connected with the elastic layer 30 without being directly connected with the glue layer 20.
Further, referring to fig. 5 and 6, in some embodiments, the elastic layer 30 includes a first surface 31 and a second surface 32 opposite to each other, the first surface 31 is connected to the glue layer 20, one end of the supporting strip 41 facing the glue layer 20 is flush with the first surface 31 or is covered by the elastic layer 30, and one end of the supporting strip 41 away from the glue layer 20 protrudes from the second surface 32.
Thus, when one end of the supporting bar 41 is flush with the first surface 31 or one end of the supporting bar 41 can be covered by the elastic layer 30, the other end of the supporting bar 41 can protrude out of the second surface 32 to support the guiding shaft 201, so that the guiding shaft 201 can well support the flexible display screen module 100, and meanwhile, the guiding shaft 201 cannot directly contact with the elastic layer 30 to cause abrasion of the elastic layer 30 and reduce the service life of the flexible display screen module.
Specifically, in one example, the end of the supporting strip 41 facing the adhesive layer 20 is flush with the first surface 31, that is, the end of the supporting strip 41 facing the adhesive layer 20 directly contacts the adhesive layer 20, so that the adhesive layer 20 can adhere to the supporting strip 41 to prevent the supporting strip 41 from falling out of the elastic layer 30. At this time, the supporting bars 41 penetrate through the elastic layer 30, that is, the elastic layer 30 is sandwiched between different supporting bars 41, the material used for the elastic layer 30 is small, and the elastic layer 30 can absorb the pressure generated by the relative displacement between the supporting bars 41, so as to avoid the phenomenon of extrusion and aggregation of the supporting bars 41. Meanwhile, the elastic layer 30 can apply a repulsive force to the supporting bars 41 at the time of recovery to restore the supporting bars 41 to a uniformly distributed state.
In another example, when the end of the supporting bar 41 facing the adhesive layer 20 is covered by the elastic layer 30 and cannot directly contact the adhesive layer 20, the end of the supporting bar 41 is completely covered by the elastic layer 30, and the elastic layer 30 can absorb the pressure in the direction perpendicular to the flexible display screen 10, so as to prevent the supporting bar 41 from directly pushing the flexible display screen 10 to generate a protrusion. Meanwhile, the elastic layer 30 semi-surrounds the supporting bars 41 to bear the pressure of the supporting bars 41 in different directions, so as to prevent the supporting bars 41 from damaging the flexible display screen module 100.
Referring to fig. 4, one end of the supporting bar 41 away from the adhesive layer 20 protrudes from the second surface 32, so that the guiding shaft 201 directly contacts the supporting bar 41, and the guiding shaft 201 is prevented from directly contacting the elastic layer 30.
Still further, referring to fig. 7 and 8, in some embodiments, the elastic layer 30 includes a first surface 31 and a second surface 32 opposite to each other, the first surface 31 is connected to the glue layer 20, an end of the supporting strip 41 facing the glue layer 20 is flush with the first surface 31 or is covered by the elastic layer 30, and an end of the supporting strip 41 away from the glue layer 20 is flush with the second surface 32.
Thus, one end of the supporting bar 41 can be directly connected to the adhesive layer 20, or one end of the supporting bar 41 can be covered by the elastic layer 30, and the other end of the supporting bar 41 is flush with the second surface 32, so that the guiding shaft 201 can simultaneously support the supporting bar 41 and the elastic layer 30 to support the flexible display screen module 100.
Specifically, one end of the supporting bar 41 away from the glue layer 20 is flush with the second surface 32, so that the guiding shaft 201 can contact the elastic layer 30 and the supporting bar 41 at the same time, and the continuity of the movement of the flexible display screen module 100 on the guiding shaft 201 is ensured. The elastic layer 30 and the supporting bars 41 can bear the pressure of the guide shaft 201 on the flexible display screen module 100, so that the flexible display screen 10 is prevented from shaking.
Referring to fig. 7 to 9, in some embodiments, the cross-sectional shape of the supporting bars 41 along the stacking direction of the flexible display screen 10, the adhesive layer 20 and the elastic layer 30 is rectangular or inverted trapezoidal.
Thus, the rectangular support bar 41 is easy to manufacture, and the inverted trapezoidal support bar 41 is not easy to fall out of the elastic layer 30.
Specifically, in the embodiment of the present application, the specific shape of the supporting bar 41 is not limited, and the requirement may be satisfied. When the support bar 41 has a rectangular cross-sectional shape, i.e. the support bar 41 is a rectangular bar, the support bar 41 can be made of the existing standard parts, and the support bar 41 is stressed evenly. The cross-sectional shape of the support bar 41 is inverted trapezoid, that is, when the support bar 41 is a trapezoid bar, one end of the long side of the support bar 41 is disposed in the elastic layer 30, and one end of the short side is in contact with the guide shaft 201, so that the support bar 41 can be prevented from falling out of the elastic layer 30, and meanwhile, the inverted trapezoid shape can be used for preventing the extension part 12 from interfering with the adjacent support bar 41 when being bent.
Referring to fig. 4 and 10, in some embodiments, the support assembly 40 further includes a support plate 42, the support plate 42 is spaced apart from the support bars 41, and the support plate 42 is stacked on the flat portion 11.
Thus, the supporting plate 42 is stacked on the flat portion 11 to support the flat portion 11, and the supporting plate 42 and the supporting bar 41 are spaced at the lowest layer of the flexible display module 100 to support the flexible display module 100 together, so that the flat portion 11 and the extending portion 12 can be kept flat.
Specifically, the supporting plate 42 is stacked on the adhesive layer 20 at the bottom of the flat portion 11, so that the supporting plate 42 can support the flat portion 11 of the flexible display module 100, and has the same function as the supporting bars 41 supporting the extension portions 12. The flat portion 11 is designed as a support plate 42 since it does not need to be bent.
In other embodiments, the support strips 41 may be disposed on the adhesive layer 20 of the flat portion 11, or the elastic layer 30 may be stacked on the flat portion 11 and the support strips 41 may be disposed on the elastic layer 30 to ensure the integrity of the flexible display screen module 100, so that all regions of the flexible display screen module 100 can be bent.
In the embodiment of the present application, the material of the supporting plate 42 is not limited, and the supporting plate 42 may be the same as the supporting strip 41, for example, the supporting plate 42 may be a supporting steel plate, and the supporting strip 41 may be a supporting steel strip, which meets the requirement.
Referring to fig. 10 and 11, in some embodiments, the supporting assembly 40 further includes a plurality of reinforcing ribs 43, and at least two adjacent supporting bars 41 of the plurality of supporting bars 41 are connected by the reinforcing ribs 43 to form a supporting unit 44.
Therefore, the reinforcing ribs 43 can connect different supporting bars 41 to enhance the supporting strength of the supporting unit 44, so that the supporting unit 44 can support the flexible display screen module 100 to be flat. Meanwhile, the reinforcing ribs 43 can keep the distance between two adjacent supporting bars 41, and the problem of aggregation between the supporting bars 41 is avoided.
Specifically, it can be understood that, after the support units 44 are formed by using the reinforcing ribs 43 to be connected, the reinforcing ribs 43 can maintain the distance between the adjacent two support bars 41. Like this, probably appear being close to or keeping away from the problem between the different support unit 44, can not lead to the fact the influence to flexible display screen 10, owing to there is strengthening rib 43 to connect between the different support bars 41, unable relative displacement, and then avoid appearing the problem of many support bars 41 aggregations, therefore can directly set up support unit 44 on glue film 20, and do not set up elastic layer 30. Of course, the elastic layer 30 may be provided to dispose the supporting unit 44 on the elastic layer 30 so that the elastic layer 30 can absorb the pressure transmitted from the guide shaft 201 to the supporting unit 44.
Referring to fig. 10 and 11, in some embodiments, two adjacent supporting bars 41 are connected by at least two reinforcing ribs 43.
So, adjacent support bar 41 links together through at least two strengthening ribs 43 for support unit 44 can be constituteed to a plurality of adjacent support bars 41, and support unit 44 supports flexible display screen module 100, guarantees the planarization of flexible display screen 10. The two or more reinforcing ribs 43 can enhance the strength of the supporting unit 44, thereby avoiding stress concentration and aggregation and skewing between different supporting bars 41 which may occur during the movement of the flexible display screen module 100.
Specifically, the number of the reinforcing ribs 43 between two adjacent supporting bars 41 may be two, and the two reinforcing ribs 43 are respectively disposed at two ends of the supporting bars 41, so as to prevent the different supporting bars 41 from being inclined. It can be understood that, in the embodiment of the present application, the number of the reinforcing ribs 43 between two adjacent supporting bars 41 is not limited, and the requirement may be satisfied.
Referring to fig. 10, in some embodiments, the number of the supporting units 44 is at least two.
Therefore, the plurality of supporting units 44 can support the flexible display screen module 100 together, the smoothness of the flexible display screen 10 is ensured, and meanwhile, the different supporting units 44 are not connected to enable the bending capacity of the extension portion 12 to be stronger.
Specifically, in the embodiment of the present application, the number of the supporting units 44 is not limited, and may be sufficient. It will be appreciated that the support bars 41 are connected together by the ribs 43, and the integrity is stronger, which ensures the flatness of the flexible display screen 10. And the different supporting units 44 are not connected with each other, so that the expansion parts 12 of the different supporting units 44 can be bent relatively, and the bending capability is stronger.
Referring to fig. 11, in some embodiments, the thickness L of the supporting bars 41 is greater than the thickness H of the reinforcing ribs 43.
Thus, the thickness H of the reinforcing rib 43 is smaller than the thickness L of the supporting bar 41, so that the supporting unit 44 can be bent more easily, and meanwhile, the damage to other elements caused by the overlarge rebound force of the compressed reinforcing rib 43 can be avoided.
Specifically, the reinforcing ribs 43 are disposed on the side close to the glue layer 20, so that the surface of the reinforcing ribs 43 close to the glue layer 20 is flush with the surface of the supporting strip 41 close to the glue layer 20, and is adhered to the glue layer 20 or covered by the elastic layer 30 at the same time. When the different support bars 41 are pressed to generate relative displacement, the reinforcing ribs 43 can generate rebound force to push the support bars 41 to return to the original position. The thickness H of the reinforcing ribs 43 is smaller than the thickness L of the supporting bars 41, so that the supporting bars 41 can be prevented from contacting other elements due to excessive rebound force, and the other elements can be prevented from being damaged.
Further, referring to fig. 11, in some embodiments, the thickness L of the supporting strip 41 is 0.1-0.3 mm; the thickness H of the reinforcing ribs 43 is 0.03-0.1 mm. For example, the thickness L of the supporting bar 41 may be 0.1mm, 0.2mm, 0.3 mm; the thickness H of the rib 43 may be 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1 mm.
Thus, the thickness L of the supporting bar 41 is set within this range, which can not only support the display panel, but also prevent the display panel from bending the flexible display module 100.
It will be appreciated that the thickness L of the support bar 41 is greater than the thickness H of the reinforcing ribs 43, for example, when the thickness L of the support bar 41 is 0.1mm, the thickness H of the reinforcing ribs 43 should be less than 0.1mm, and the thickness H of the reinforcing ribs 43 can be 0.03mm or 0.04 mm.

The net-shaped supporting layer 50 can also stretch the side edges to shape the curved surface of the whole flexible display screen module 100, and simultaneously isolate the bending side stress of the bar supporting bars 41 to ensure the flatness of the flexible display screen 10. In addition, it should be noted that the glue layer 20 can also stretch the side edges, so as to shape the curved surface of the flexible display screen module 100 and isolate the bending side stress of the supporting bars 41.

Specifically, the foam layer 60 and the mesh support layer 50 work together to separate the flexible display screen 10 from the adhesive layer 20, so that the pressure generated by the support strip 41, the elastic layer 30 and the adhesive layer 20 can be absorbed by the foam layer 60 and the mesh support layer 50. The foam layer 60 and the mesh support layer 50 may also support the flexible display screen 10, delaying the life of the entire flexible display screen module 100. The foam layer 60 may be foam glue to eliminate the impression of the hard layer such as the mesh support layer 50.

In steps 02 and 03, the first surface 31 of the elastic layer 30 is coated with the adhesive layer 20, and the second surface 32 is formed with the supporting bars 41. In some embodiments, the supporting bars 41 may be replaced by supporting units 44, and the supporting units 44 are formed on the second surface 32 of the elastic layer 30.

Specifically, it is understood that the elastic layer 30 may be made of at least one of thermoplastic polyurethane elastomer rubber, polyamide resin, and acryl, and may be solidified by a flowing gel to form an elastic solid state. Therefore, in step 05, the process film 400 may include a substrate 401 to support the material of the elastic layer 30 and other layers, after the plurality of supporting bars 41 are uniformly disposed, an elastic adhesive is sprayed or blade-coated on the side where the plurality of supporting bars 41 are disposed, and after the adhesive is solidified to form the elastic layer 30, the elastic layer 30 covers the plurality of supporting bars 41. In addition, the substrate 401 may include a transfer layer 402, the transfer layer 402 may be stacked on the substrate 401, and the transfer layer 402 may lose its viscosity after being irradiated with ultraviolet rays or heated, so that the entire process film 400 is separated from the elastic layer 30.
