Description

Technical Field

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

[0002] In order to reduce the border size of the display device and increase the screen-to-body ratio, a substrate bending process is usually used to bend the display panel of the display module to form a substrate bending area, and a connecting circuit is provided in the substrate bending area.

[0003] In the related art, the pad bending area is directly exposed to the outside without any protective measures, so that when the display panel is impacted by external force, the connection lines in the pad bending area are easily damaged. At the same time, the bending shape of the pad bending area is also easily deformed under the action of external force, thus affecting the assembly of the whole machine. Summary of the invention

[0004] The embodiments of the present application provide a display module and a display device, which can protect the bending area to prevent the connection lines in the bending area from being damaged or broken due to external force impact, and the bending area from being deformed.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a display module for a display device, the display module comprising: a display panel, a supporting structure and a first platform, the display panel comprising a first non-bending area, a bending area and a second non-bending area connected in sequence, the first non-bending area having a light emitting surface, the second non-bending area being stacked on a side of the first non-bending area facing away from the light emitting surface; the supporting structure being stacked between the first non-bending area and the second non-bending area; the first platform being connected to the supporting structure, and the first platform being located on a side of the bending area away from the supporting structure.

[0007] In this way, by setting the first platform, and the first platform is located on the side of the bending zone away from the supporting structure, the bending zone can be prevented from leaking out, and the first platform has a protective effect on the bending zone. When the display panel is impacted by external force, the external force will directly act on the first platform, and will not impact the bending zone. In this way, the connection line in the bending zone can be prevented from being damaged or broken under the impact of external force, thereby improving the stability and reliability of the display module. At the same time, the bending zone will not be deformed due to the pressure of external force, thereby ensuring that the assembly of the whole machine is not affected. In addition, under the action of its own bending stress, the bending zone is prone to problems such as film peeling and cracking. When the bending zone expands outward along the Y-axis direction, the bending stress will increase, and the risk of film peeling and cracking in the bending zone will increase. By setting the first platform, the first platform can prevent the bending zone from expanding outward along the Y-axis direction, thereby reducing the risk of film peeling (Pad Bending Peeling) or cracking in the bending zone.

[0008] In a possible implementation of the first aspect, the first platform is connected to the bending zone. The first platform is connected to the protective layer, thereby achieving connection between the bending zone and the first platform. That is, the bending zone is connected to the first platform through the protective layer, so that the bending zone can be supported on the first platform, and the bending shape of the bending zone can be better fixed, and the bending zone is not easily deformed or expanded along the Y-axis direction.

[0009] In a possible implementation of the first aspect, a first adhesive material is provided between the first platform and the bending zone, and the first platform and the bending zone are connected by the first adhesive material. That is, the first platform and the bending zone can be connected together by gluing. The connection method is simple and easy to operate, and the connection between the first platform and the bending zone is firm and reliable.

[0010] In a possible implementation of the first aspect, the display module further includes a connecting arm, one end of the connecting arm is connected to the supporting structure, and the other end of the connecting arm extends toward the first platform and is connected to the first platform. The supporting structure and the first platform are connected by the connecting arm, and the connection structure is simple and the connection is convenient.

[0011] In a possible implementation of the first aspect, the connecting arm includes a first connecting arm and a second connecting arm spaced apart from each other, the first connecting arm and the second connecting arm are respectively connected to the two ends of the first platform, and a clearance opening is defined between the first connecting arm, the second connecting arm, the first platform and the supporting structure, and the bending zone is arranged in the clearance opening. The two ends of the first platform are respectively connected to the supporting structure through the first connecting arm and the second connecting arm, thereby making the connection balance between the first platform and the supporting structure better, the connection is more stable and reliable, and the first platform is not easy to shake or break with the supporting structure when impacted by external force. In addition, a clearance opening is defined between the first connecting arm, the second connecting arm, the first platform and the supporting structure, and the bending zone is arranged in the clearance opening. In this way, the first connecting arm and the second connecting arm will not interfere with the bending zone while enhancing the connection balance and stability between the first platform and the supporting structure, thereby affecting the PadBending process of the display panel.

[0012] In a possible implementation of the first aspect, the support structure, the first platform and the connecting arm are all made of metal. Since metal materials have high structural rigidity, by making the support structure, the first platform and the connecting arm all made of metal, the first platform can be stably supported on a side of the bending zone away from the support structure. When impacted by an external force, the first platform is not likely to shake or break with the support structure.

[0013] In a possible implementation of the first aspect, the support structure, the first platform, and the connecting arm are all made of titanium, titanium alloy, copper, copper alloy, silver, or silver alloy. In this way, not only the structural rigidity of the support structure, the first platform, and the connecting arm is high, but also the heat dissipation and electrical conductivity of the support structure are better.

[0014] In a possible implementation of the first aspect, the support structure, the connecting arm and the first platform are integrally formed, thereby not only making the connection strength between the support structure and the connecting arm, and between the connecting arm and the first platform high and less prone to breakage, but also eliminating the need for connecting steps between the support structure and the connecting arm, and between the connecting arm and the first platform, thereby simplifying the assembly process.

[0015] In a possible implementation of the first aspect, the display module further includes a cushioning layer, the cushioning layer is located between the first non-bending area and the second non-bending area, and the cushioning layer and the support structure are stacked. The cushioning layer also plays a supporting role between the first non-bending area and the second non-bending area, ensuring the spacing between the first non-bending area and the second non-bending area, and further ensuring the bending radius of the bending area. The thickness of the support structure can be reduced by providing the cushioning layer.

[0016] In a possible implementation of the first aspect, the display module further includes a protective layer, the protective layer at least covers the bending area, the protective layer is located between the bending area and the first platform, and the first adhesive is located between the protective layer and the first platform. The bending area is provided with a connecting line, and by making the protective layer at least cover the bending area, the protective layer can cover the connecting line arranged in the bending area. In this way, when the display panel is bent in the bending area, the protective layer covering the bending area is first subjected to the stress generated when the display panel is bent, and in the process of further bending, the connecting line arranged in the bending area will be immediately subjected to the bending stress. Since the protective layer is first subjected to the bending stress and can offset a part of the bending stress, the stress on the connecting line when the display panel is bent is reduced, thereby being able to protect the connecting line arranged in the bending area. In this way, it can be avoided that the connecting line is broken due to the pulling force during bending or the connecting line and the substrate are peeled off, which leads to poor display of the display panel and affects the reliability of the display panel. In addition, the protective layer can also prevent the bending area from being scratched by external forces.

[0017] In a possible implementation of the first aspect, the display module further includes a second platform, the second platform is connected to the support structure, and the second platform is located between the bending area and the support structure. By arranging the second platform on the side of the bending area facing the support structure, when the bending area is deformed by external force impact, the second platform can abut against the bending area, so that the degree of deformation of the bending area can be controlled, and the bending area is prevented from being deformed to a large extent under the impact of external force, thereby reducing the risk of pad bending peeling or cracking in the bending area.

[0018] In a possible implementation of the first aspect, a second adhesive material is provided between the second platform and the bending zone, and the second platform and the bending zone are connected by the second adhesive material. The second platform and the bending zone can be connected together by gluing. The connection method is simple and easy to operate, and the second platform and the bending zone are firmly connected and have high reliability.

[0019] In a possible implementation of the first aspect, the display module also includes a light-transmitting cover plate, which is stacked on the side where the light-emitting surface of the first non-bending zone is located, and a first protective cover is provided between the light-transmitting cover plate and the first platform, and the first protective cover is provided on the side of the bending zone away from the supporting structure. In this way, not only the first platform can protect the bending zone, but the first protective cover can also protect the bending zone. And the first protective cover can cover the area between the first platform and the light-transmitting cover plate. When the direction of the external force applied to the display panel points to the area between the first platform and the light-transmitting cover plate, the external force will directly act on the first protective cover without directly impacting the bending zone. Therefore, the first protective cover can further protect the bending zone from external force impact. Thereby, the problem of damage and breakage of the bending zone under external force impact can be better avoided, and the stability and reliability of the display of the display panel can be improved.

[0020] In a possible implementation of the first aspect, the display module also includes a second protective cover, the second protective cover is arranged between the second non-bending area and the first platform, and the second protective cover is arranged on the side of the bending area away from the supporting structure. In this way, not only the first platform can protect the bending area, but the second protective cover can also protect the bending area. And the second protective cover can cover the area between the second non-bending area and the first platform. When the external force applied to the display panel is directed to the area between the second non-bending area and the first platform, the external force will directly act on the second protective cover without directly impacting the bending area. Therefore, the second protective cover can further protect the bending area from external force impact. Thereby, the problem of damage and breakage of the bending area under the impact of external force can be better avoided, and the stability and reliability of the display of the display panel can be improved.

[0021] In a possible implementation of the first aspect, a lifting member is provided on a side of the second non-bending zone away from the supporting structure, and the second protective cover is provided between the lifting member and the first platform. By providing the lifting member and supporting the second protective cover between the lifting member and the first platform, the lifting member has a lifting effect on the second protective cover. By adjusting the height of the lifting member along the Z-axis direction, the spacing between the second protective cover and the bending zone can be adjusted.

[0022] In a possible implementation of the first aspect, the display module also includes a first connecting portion, the first connecting portion is connected to the first platform, the first protective cover is connected between the light-transmitting cover plate and the first connecting portion, the second protective cover is connected between the second non-bending area and the first connecting portion, and the first protective cover, the first connecting portion and the second protective cover are an integrally formed part. By providing the first connecting portion and connecting the first connecting portion to the first platform, not only can the connection between the first protective cover, the second protective cover and the first platform be achieved, but also the first protective cover and the second protective cover can be connected together. And by making the first protective cover, the first connecting portion and the second protective cover an integrally formed part, not only the connection strength between the first protective cover and the first connecting portion, and between the second protective cover and the first connecting portion is high and not prone to breakage, but also the connection process between the first protective cover and the first connecting portion and the connection process between the second protective cover and the first connecting portion can be omitted, thereby simplifying the assembly process.

[0023] In a possible implementation of the first aspect, the first protective cover and the second protective cover are both Mayler parts. Mayler materials have good flexibility, so that the first protective cover and the second protective cover can both have good flexibility. When subjected to external impact, the first protective cover and the second protective cover can be elastically deformed, thereby weakening the impact force transmitted to the display panel and the first platform. That is, by making the first protective cover a Mayler part, the first protective cover has a good buffering effect.

[0024] In a second aspect, an embodiment of the present application provides a display device, comprising: a housing and a display module, wherein the display module is the display module in any of the above technical solutions, and the display module is arranged on the housing.

[0025] Since the display device provided in the second aspect of the present application includes a display module of any technical solution of the first aspect above, the two can solve the same problem and achieve the same effect. BRIEF DESCRIPTION OF THE DRAWINGS

The back cover 21 is a 3D back cover 21. The frame 22 is fixed to the back cover 21, and the frame 22 is arranged around the edge of the back cover 21. Exemplarily, the frame 22 can be fixedly connected to the back cover 21 by adhesive. The frame 22 can also be an integrally molded structure with the back cover 21, that is, the frame 22 and the back cover 21 are an integral structure.

Specifically, the display module 10 may include a transparent cover plate 109a and a display panel 101. The transparent cover plate 109a is stacked with the display panel 101. The transparent cover plate 109a is mainly used to protect the display panel 101 and prevent dust.

It can be understood that in other embodiments, the display module 10 may not include the light-transmitting cover plate 109a.

[0069] See also Figure 3 Combined with Figure 4 , Figure 3 for Figure 1 The schematic diagram of the display module 10 shown in FIG. Figure 4 The display module 10 provided in some embodiments of the present application is Figure 3 The cross-sectional view at the BB line. It can be understood that Figure 3-Figure 4 The following figures and the related drawings only schematically show some components of the display module 10, and the actual shapes, sizes, positions and structures of these components are not subject to Figure 3-Figure 4 and the accompanying drawings below.

[0070] The display panel 101 includes a substrate, a circuit layer and a display layer stacked in sequence, and the display layer is electrically connected to the circuit layer. The side of the display layer away from the substrate is the display surface, and the transparent cover plate 109a is stacked on the side of the display layer away from the substrate. In order to reduce the frame size of the display device 100 and increase the screen-to-body ratio, the substrate is usually bent by a substrate bending process, so that the display panel 101 may include a first non-bending area 101a, a bending area 101b (pad bending area) and a second non-bending area 101c connected in sequence.

[0071] The first non-bending area 101a has a light-emitting surface, that is, the display layer is located in the first non-bending area 101a, and the display surface of the display layer is the light-emitting surface. The light-emitting surface of the first non-bending area 101a is used to display images, videos, etc. When the display module 10 is in use, the light-emitting surface of the first non-bending area 101a faces the user to present images or videos to the user. The transparent cover plate 109a is stacked on the side where the light-emitting surface of the first non-bending area 101a is located.

[0072] It should be noted that the light-emitting area of ​​the first non-bending zone 101a constitutes the display area. The entire area of ​​the first non-bending zone 101a may constitute the display area, that is, in this case, the first non-bending zone 101a is entirely composed of the display area; or only a part of the first non-bending zone 101a constitutes the display area, that is, in this case, the first non-bending zone 101a is composed of the display area and the non-display area.

[0073] The second non-bending area 101c is stacked on the side of the first non-bending area 101a facing away from the light emitting surface. Specifically, the second non-bending area 101c is bent through the bending area 101b to the side of the first non-bending area 101a facing away from the light emitting surface, thereby reducing the frame size of the display device 100 and achieving a high screen-to-body ratio.

[0074] Among them, the circuit layer includes a pixel driving circuit located in the first non-bending area 101a and a driving chip IC located in the second non-bending area 101c. The driving chip IC is electrically connected to the pixel driving circuit through a connecting line arranged in the bending area 101b, and provides a driving signal to the pixel driving circuit through the connecting line to drive the display layer to display.

[0075] For example, see Figure 3 and Figure 4 , the bending region 101b may be located on one side of the first non-bending region 101a along the Y-axis direction, and the first non-bending region 101a and the second non-bending region 101c may be stacked along the Z-axis direction. In some other examples, the bending region 101b may also be located on one side of the first non-bending region 101a along the X-axis direction.

[0076] In order to make the display panel 101 easy to bend, the display panel 101 may be a flexible display panel. For example, the display panel 101 may be an organic light-emitting diode (OLED) display panel, or an active matrix organic light-emitting diode (AMOLED) display panel.

[0077] On this basis, the substrate can be a flexible substrate. The substrate can be formed of any suitable insulating material with flexibility. Exemplarily, the substrate can be an organic polymer or an organic-inorganic doped composite. Among them, the organic polymer can be polyimide (PI), polyethylene terephthalate (PET), etc. The inorganic-organic doped composite can be an organic polymer such as polyimide doped with glass fiber. Since the glass fiber has high toughness, the flexible strength of the substrate can be significantly improved, so that the display panel 101 is not easy to break and peel off when bent.

[0078] Of course, the display panel 101 can also be partially a flexible display panel and partially a rigid display panel. For example, the first non-bending area 101a and the second non-bending area 101c can be set as a rigid display panel, and the bending area 101b can be set as a flexible display panel. Correspondingly, the substrate of the first non-bending area 101a and the substrate of the second non-bending area 101c can be a rigid substrate, and the substrate of the bending area 101b can be a flexible substrate.

[0079] The display module 10 further includes a support structure 102, which is stacked between the first non-bending area 101a and the second non-bending area 101c, and plays a supporting role between the first non-bending area 101a and the second non-bending area 101c. The support structure 102 allows a certain distance between the first non-bending area 101a and the second non-bending area 101c, and supports both ends of the bending area 101b, so that the bending area 101b of the display panel 101 can maintain a certain bending radius.

[0080] For related technologies, see Figure 4 and Figure 5 ,in Figure 5 for Figure 4 In the main view of the support structure 102 shown in the figure, the bending area 101b is directly exposed to the outside without any protective measures. Since the bending area 101b is provided with a connecting line, the connecting line of the bending area 101b is easily damaged or broken when the display panel 101 is impacted by an external force, which in turn causes the display panel 101 to display poorly and the reliability of the display panel 101 is low. At the same time, since the bending area 101b is supported and fixed only at two ends by the support structure 102, the main part of the bending area 101b is formed into a suspended bending shape. When the bending area 101b is pressed by an external force, it is very easy to deform, thereby affecting the assembly of the whole machine.

[0081] To solve the above technical problems, please refer to Figure 6 and Figure 7 ,in Figure 6The display module 10 provided in some other embodiments of the present application is Figure 3 A cross-sectional view at line BB, wherein the display panel 101 is not subjected to pad bending. Figure 7 for Figure 6 The display module 10 shown in Figure 3 The cross-sectional view at the BB line, wherein the display panel 101 has been subjected to pad bending. In this embodiment, the display module 10 includes not only the transparent cover plate 109 a , the display panel 101 and the support structure 102 , but also a first platform 103 .

[0082] Specifically, the first platform 103 is connected to the support structure 102, and the first platform 103 is located on the side of the bending area 101b away from the support structure 102. For example, please refer to Figure 6 and Figure 7 The support structure 102 and the first platform 103 can be arranged at intervals along the Y-axis direction, and the bending area 101b is located between the support structure 102 and the first platform 103.

[0083] Here, the support structure 102 not only supports the first non-bending area 101a and the second non-bending area 101c to be spaced apart by a certain distance and supports both ends of the bending area 101b, but also has the function of connecting the first platform 103. By connecting the first platform 103 to the support structure 102, the first platform 103 is supported and fixed on the side of the bending area 101b away from the support structure 102.

[0084] In this way, by setting the first platform 103, and the first platform 103 is located on the side of the bending area 101b away from the support structure 102, it is possible to avoid leakage of the bending area 101b, and the first platform 103 has a protective effect on the bending area 101b. When the display panel 101 is impacted by an external force, the external force will directly act on the first platform 103, and will not impact the bending area 101b. In this way, the connection line of the bending area 101b can be prevented from being damaged or broken under the impact of external force, thereby improving the stability and reliability of the display of the display module 10. At the same time, the bending area 101b will not be deformed due to the pressure of external force, thereby ensuring that the assembly of the whole machine is not affected.

[0085] In addition, under the effect of its own bending stress, the bending area 101b is prone to film peeling, cracking and other problems. When the bending area 101b expands outward along the Y-axis direction, the bending stress will increase, and the risk of film peeling and cracking in the bending area 101b will increase. By setting the first platform 103, the first platform 103 can prevent the bending area 101b from expanding outward along the Y-axis direction, thereby reducing the risk of film peeling (Pad Bending Peeling) or cracking in the bending area 101b.

[0086] In some embodiments, see Figure 6 and Figure 7 , the display module 10 further includes a protective layer 109c, the protective layer 109c at least covers the bending area 101b, and the protective layer 109c is located between the bending area 101b and the first platform 103. That is, in some examples, the protective layer 109c may only cover the bending area 101b; in other examples, while the protective layer 109c covers the bending area 101b, the protective layer 109c may also extend toward the first non-bending area 101a, and similarly, the protective layer 109c may also extend toward the second non-bending area 101c.

[0087] It can be understood that the bending area 101b is provided with a connection circuit, and by making the protective layer 109c at least cover the bending area 101b, the protective layer 109c can cover the connection circuit provided in the bending area 101b. In this way, when the display panel 101 is bent in the bending area 101b, the protective layer 109c covering the bending area 101b is first subjected to the stress generated when the display panel 101 is bent, and in the further bending process, the connection circuit provided on the bending area 101b will be subjected to the bending stress immediately.

[0088] Since the protective layer 109c is first subjected to the bending stress, it can offset a part of the bending stress, so that the stress on the connecting circuit is reduced when the display panel 101 is bent, so that the connecting circuit arranged in the bending area 101b can be protected. In this way, it can be avoided that the connecting circuit is broken due to the pulling force during bending, or the connecting circuit is peeled off from the substrate, which in turn causes the display panel 101 to display poorly and affects the reliability of the display panel 101. In addition, the protective layer 109c can also prevent the bending area 101b from being scratched by external forces.

[0089] When the protective layer 109c extends toward the first non-bending area 101a, the protective layer 109c can also cover the connection between the first non-bending area 101a and the bending area 101b. In this way, when the display panel 101 is bent, the protective layer 109c can also offset a portion of the bending stress at the connection between the first non-bending area 101a and the bending area 101b, thereby reducing the risk of film peeling at the connection between the first non-bending area 101a and the bending area 101b.

[0090] When the protective layer 109c extends toward the second non-bending area 101c, the protective layer 109c can at least cover the connection between the second non-bending area 101c and the bending area 101b. In this way, when the display panel 101 is bent, the protective layer 109c can offset a portion of the stress of the bending area 101b at the connection between the second non-bending area 101c and the bending area 101b, thereby reducing the risk of film separation at the connection between the second non-bending area 101c and the bending area 101b.

[0091] The material of the protective layer 109c can be arbitrarily selected as needed. For example, the protective layer 109c can be MCL coating material or UV glue.

[0092] Based on the above examples, please continue to refer to Figure 7 By making a certain distance between the first platform 103 and the protective layer 109c, it is possible to prevent the first platform 103 from directly transmitting the impact force to the protective layer 109c and then to the bending area 101b when being impacted by an external force.

[0093] Among them, the spacing D between the first platform 103 and the protective layer 109c can be arbitrarily selected as needed. Exemplarily, the spacing D between the first platform 103 and the protective layer 109c can be greater than 0 and less than or equal to 5mm. For example, the spacing D between the first platform 103 and the protective layer 109c can be 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3.0mm, 3.5mm, 4mm, 4.5mm or 5mm. By making the spacing D between the first platform 103 and the protective layer 109c greater than 0 and less than or equal to 5mm, it can not only prevent the first platform 103 from directly transmitting the impact force to the protective layer 109c and then to the bending area 101b when it is impacted by an external force, but also prevent the frame size of the display device 100 from being too large, reducing the screen ratio. Of course, the present application is not limited to this, and the spacing D between the first platform 103 and the protective layer 109c can also be greater than 5mm.

[0094] In some other implementations, the first platform 103 and the protective layer 109c may be in direct contact, that is, there is no gap between the first platform 103 and the bending area 101b, which can further increase the screen-to-body ratio.

[0095] Furthermore, the first platform 103 and the protective layer 109c can abut against each other. In this way, the first platform 103 generates an abutting force on the bending area 101b through the protective layer 109c, thereby better preventing the bending area 101b from expanding outward along the Y-axis direction, and further reducing the risk of pad bending peeling or cracking of the bending area 101b.

[0096] In some embodiments, see Figure 8 ,in Figure 8 The display module 10 provided in some embodiments of the present application is Figure 3 In the cross-sectional view at the middle BB line, the first platform 103 is connected to the protective layer 109c. By connecting the first platform 103 and the protective layer 109c, the connection between the bending area 101b and the first platform 103 is achieved. That is, the bending area 101b is connected to the first platform 103 through the protective layer 109c, so that the bending area 101b can be supported on the first platform 103, and the bending shape of the bending area 101b can be better fixed, and the bending area 101b is not easy to deform or expand outward along the Y axis direction.

[0097] The connection method between the first platform 103 and the protective layer 109c can be arbitrarily selected according to needs. Figure 8 A first adhesive material 1031 is provided between the first platform 103 and the protective layer 109c, and the first platform 103 and the protective layer 109c are connected by the first adhesive material 1031. That is, the first platform 103 and the protective layer 109c can be connected together by gluing. The connection method is simple and easy to operate, and the connection between the first platform 103 and the protective layer 109c is firm and reliable.

[0098] In addition, the first adhesive material 1031 covers at least a portion of the protective layer 109c. In addition to achieving the above-mentioned connection function, the first adhesive material 1031 also has a protective effect on the connection line on the bending area 101b. Specifically, the first adhesive material 1031 can also offset the bending stress generated when the bending area 101b is bent, thereby preventing the connection line on the bending area 101b from being disconnected due to the pulling force during bending, or the film layer of the bending area 101b from peeling off.

[0099] Optionally, the first adhesive material 1031 can be UV adhesive, thermosetting adhesive or hot melt adhesive, so that the first adhesive material 1031 has elasticity after curing. In this way, the first adhesive material 1031 can not only connect the protective layer 109c and the first platform 103 together, but also has a buffering effect between the protective layer 109c and the first platform 103.

[0100] Specifically, when the first platform 103 is impacted by an external force, the impact force is transmitted to the protective layer 109c through the first adhesive material 1031. Since the first adhesive material 1031 is elastic, the impact force transmitted from the first platform 103 can be absorbed and weakened before being transmitted to the protective layer 109c, and then transmitted to the bending area 101b by the protective layer 109c. As a result, the impact force received by the bending area 101b will be greatly weakened, thereby reducing the risk of damage and breakage of the connection line in the bending area 101b.

[0101] Of course, the present application is not limited thereto, and the first adhesive material 1031 can be arbitrarily selected as needed. In some other examples, the first adhesive material 1031 can also be PU adhesive or PSA adhesive.

[0102] In some other embodiments, the first platform 103 and the bending area 101b may also be connected by welding, threaded connection or clamping.

[0103] In some other embodiments of the present application, the display module 10 may not include the above-mentioned protective layer 109c. Based on this:

[0104] In some embodiments, a certain distance may be provided between the first platform 103 and the bending zone 101b, so as to prevent the first platform 103 from directly transmitting the impact force to the bending zone 101b when the first platform 103 is impacted by an external force.

[0105] Furthermore, the spacing D between the first platform 103 and the bending area 101b can be greater than 0 and less than or equal to 5 mm. In this way, it can not only prevent the first platform 103 from directly transmitting the impact force to the bending area 101b when it is impacted by external force, but also prevent the frame size of the display device 100 from being too long, thereby reducing the screen-to-body ratio.

[0106] In some embodiments, the first platform 103 and the bending area 101b may be in direct contact with each other, that is, there is no gap between the first platform 103 and the bending area 101b, which can further increase the screen-to-body ratio.

[0107] Furthermore, the first platform 103 and the bending area 101b can abut against each other. In this way, the first platform 103 directly generates an abutting force on the bending area 101b, thereby better preventing the bending area 101b from expanding outward along the Y-axis direction, and further reducing the risk of pad bending peeling or cracking of the bending area 101b.

[0108] In some embodiments, the first platform 103 is connected to the bending area 101b. In this way, the bending area 101b can be directly supported on the first platform 103, so that the bending shape of the bending area 101b can be better fixed, and the bending area 101b is not easily deformed or expanded along the Y-axis direction.

[0109] Furthermore, a first adhesive material 1031 is provided between the first platform 103 and the bending area 101b, and the first platform 103 and the bending area 101b are connected by the first adhesive material 1031. In other words, the first platform 103 and the bending area 101b are connected together by gluing. The connection method is simple and easy to operate, and the connection between the first platform 103 and the protective layer 109c is firm and reliable.

[0110] In some embodiments of this application, please refer to Fig. 9 , Fig. 9 The display module 10 provided in some embodiments of the present application is Figure 3 In the cross-sectional view at the middle BB line, a first protective cover 106a is provided between the light-transmitting cover plate 109a and the first platform 103, and the first protective cover 106a is provided on the side of the bending area 101b away from the support structure 102. Specifically, one end of the first protective cover 106a is connected to the light-transmitting cover plate 109a, and the other end of the first protective cover 106a is connected to the first platform 103. That is, the first protective cover 106a is supported on the side of the bending area 101b away from the support structure 102 by being connected to the light-transmitting cover plate 109a and the first platform 103 respectively.

[0111] In this way, not only the first platform 103 can protect the bending area 101b, but the first protective cover 106a can also protect the bending area 101b. In addition, the first protective cover 106a can cover the area between the first platform 103 and the transparent cover plate 109a. When the direction of the external force applied to the display panel 101 points to the area between the first platform 103 and the transparent cover plate 109a, the external force will directly act on the first protective cover 106a, and will not directly impact the bending area 101b. Therefore, the first protective cover 106a can further protect the bending area 101b from external force impact. Thereby, the problem of damage and breakage of the bending area 101b under the impact of external force can be better avoided, and the stability and reliability of the display of the display panel 101 can be improved. At the same time, the bending area 101b will not be deformed due to the pressure of external force, thereby ensuring that the assembly of the whole machine is not affected.

[0112] Preferably, please continue to see Fig. 9 , the first protective cover 106a is separated from the bending area 101b. In this way, the first protective cover 106a and the bending area 101b will not be in direct contact. When the first protective cover 106a is impacted by an external force, the first protective cover 106a will not directly transfer the impact force to the bending area 101b, thereby better reducing the risk of damage to the bending area 101b caused by the external force impact. In some other examples, the first protective cover 106a and the bending area 101b can also be in direct contact.

[0113] Optionally, the first protective cover 106a is a Mayler piece, that is, the first protective cover 106a is made of Mayler material. Mayler material has good flexibility, so that the first protective cover 106a can have good flexibility. When it is impacted by external force, the first protective cover 106a can undergo elastic deformation, thereby weakening the impact force transmitted to the transparent cover plate 109a and the first platform 103. That is, by making the first protective cover 106a a Mayler piece, the first protective cover 106a has a better buffering effect. Of course, the present application is not limited to this. In some other examples, the first protective cover 106a can also be made of PET material or PI material; in some other examples, the first protective cover 106a can also be a steel sheet made of spring steel, etc.

[0114] Optionally, see Fig. 9, the first protective cover 106a can be formed into a plate-like structure. This makes the first protective cover 106a simple in structure and easy to process. Of course, the present application is not limited to this. In some other examples, the first protective cover 106a can also be a grid-like structure. In this way, while taking into account its protective function, it can also save costs. In addition, by forming the first protective cover 106a into a grid-like structure, the elasticity of the first protective cover 106a can also be increased, so that when the first protective cover 106a is impacted by an external force, the first protective cover 106a is not easily damaged, and the impact force transmitted to the transparent cover plate 109a and the first platform 103 can also be reduced.

[0115] For further information, please refer to Fig. 9 The first protective cover 106a can be formed into an arc-shaped structure that protrudes in a direction away from the bending area 101b. In this way, the distance between the first protective cover 106a and the bending area 101b can be increased, and when the first protective cover 106a is deformed by external impact, the risk of direct contact between the first protective cover 106a and the bending area 101b can be reduced, thereby further reducing the risk of the bending area 101b being impacted by external force.

[0116] Of course, the present application is not limited thereto, and the shape of the first protective cover 106a can be arbitrarily selected as needed. In some other examples, the first protective cover 106a can also be formed into an arc-shaped structure protruding toward the bending area 101b; or the first protective cover 106a can also be formed into a curved surface structure or a multi-section bending structure, or the first protective cover 106a can also be formed into other special-shaped structures.

[0117] Optionally, the size of the first protective cover 106a along the X-axis direction may be approximately equal to the size of the bending zone 101b along the X-axis direction. Here, "approximately equal" means equality within a certain error range, and the error range may be a range within 5 mm relative to the absolute equality deviation. In this way, along the X-axis direction, the first protective cover 106a can basically cover the bending zone 101b located between the transparent cover plate 109a and the first platform 103, and the first protective cover 106a has a wider protection range for the bending zone 101b and a better protection effect.

[0118] Alternatively, the size of the first protective cover 106a along the X-axis direction may be larger than the size of the bending area 101b along the X-axis direction. In this way, along the X-axis direction, the first protective cover 106a may cover the entire bending area 101b between the transparent cover plate 109a and the first platform 103, and the first protective cover 106a has a wider protection range for the bending area 101b and a better protection effect.

[0119] In some embodiments of this application, please continue to refer to Fig. 9, the display module 10 further includes a second connection portion 108b, and the first protective cover 106a is connected to the light-transmitting cover plate 109a via the second connection portion 108b. Specifically, the second connection portion 108b is connected to the light-transmitting cover plate 109a, and the first protective cover 106a is connected to the second connection portion 108b. Based on this, the connection between the first protective cover 106a and the light-transmitting cover plate 109a is more flexible, and the shape selection range of the first protective cover 106a is wider.

[0120] Specifically, in order to ensure the reliability of the connection with the transparent cover plate 109a, it is sufficient to ensure that the shape of the second connecting portion 108b is adapted to the connection structure between it and the transparent cover plate 109a, and the shape of the first protective cover 106a may not be limited by the connection requirements. Fig. 9 , the second connection portion 108b can be formed into a flat plate, and the first protective cover 106a can be formed into an arc-shaped plate structure. Of course, the present application is not limited thereto. In some other examples, the second connection portion 108b and the first protective cover 106a can also have the same shape. For example, the second connection portion 108b and the first protective cover 106a can both be arc-shaped plate structures.

[0121] For further information, please refer to Fig. 9 , the second connecting portion 108b and the light-transmitting cover plate 109a are connected together by the third adhesive material 109a1. That is to say, the second connecting portion 108b and the light-transmitting cover plate 109a are connected together by gluing. The connection method is simple, easy to operate, and has good connection reliability. The third adhesive material 109a1 can be arbitrarily selected as needed. For example, the third adhesive material 109a1 can be PU adhesive or PSA adhesive. In some other examples, the second connecting portion 108b and the light-transmitting cover plate 109a can also be connected by welding, threaded connection, or clamping connection.

[0122] The position where the second connecting portion 108b is connected to the light-transmitting cover plate 109a can be selected arbitrarily as needed. For example, please continue to refer to Fig. 9 , the second connection portion 108b may be connected to the surface of the transparent cover plate 109a facing away from the display panel 101. In some other examples, the second connection portion 108b may also be connected to the surface of the transparent cover plate 109a facing the display panel 101; or the second connection portion 108b may also be connected to the end surface of one end of the transparent cover plate 109a along the Y-axis direction.

[0123] Optionally, the second connection portion 108b and the first protective cover 106a may be an integrally formed part. This not only improves the connection strength between the second connection portion 108b and the first protective cover 106a, but also eliminates the connection step between the second connection portion 108b and the first protective cover 106a, simplifying the assembly process. In some other examples, the second connection portion 108b and the first protective cover 106a may also be separate structural parts.

[0124] In some embodiments of this application, please continue to refer to Fig. 9 The display module 10 further includes a first connection portion 108a, and the first protective cover 106a is connected to the first platform 103 through the first connection portion 108a. Specifically, the first connection portion 108a is connected to the first platform 103, and the first protective cover 106a is connected between the light-transmitting cover plate 109a and the first connection portion 108a. Based on this, the connection between the first protective cover 106a and the first platform 103 is more flexible, and the shape selection range of the first protective cover 106a is wider.

[0125] Specifically, in order to ensure the reliability of the connection with the first platform 103, it is sufficient to ensure that the shape of the first connecting portion 108a is adapted to the connection structure between it and the first platform 103, and the shape of the first protective cover 106a may not be affected by the connection requirements. Fig. 9 , the first connection portion 108a can be formed into a flat plate, and the first protective cover 106a can be formed into an arc-shaped plate structure. Of course, the present application is not limited thereto. In some other examples, the shapes of the first connection portion 108a and the first protective cover 106a can also be the same. For example, the first connection portion 108a and the first protective cover 106a can both be arc-shaped plate structures.

[0126] For further information, please refer to Fig. 9 , the first connection part 108a and the first platform 103 are connected together by the fourth adhesive material 1032. That is to say, the first connection part 108a and the first platform 103 are connected together by gluing. The connection method is simple, easy to operate, and has good connection reliability. The fourth adhesive material 1032 can be arbitrarily selected as needed. For example, the fourth adhesive material 1032 can be PU adhesive or PSA adhesive. In some other examples, the first connection part 108a and the first platform 103 can also be connected by welding, threaded connection, or clamping connection.

[0127] The position where the first connecting portion 108a is connected to the first platform 103 can be selected arbitrarily as needed. For example, please continue to refer to Fig. 9, the first connection portion 108a can be connected to the surface of the first platform 103 facing away from the bending zone 101b. In some other examples, the first connection portion 108a can also be connected to the surface of the first platform 103 facing the bending zone 101b, or the first connection portion 108a can also be connected to the end surface of one end of the first platform 103 along the Z-axis direction.

[0128] Optionally, the first connection portion 108a and the first protective cover 106a may be an integrally formed part. This not only improves the connection strength between the first connection portion 108a and the first protective cover 106a, but also saves the connection step between the first connection portion 108a and the first protective cover 106a, thus simplifying the assembly process. In some other examples, the first connection portion 108a and the first protective cover 106a may also be separate structural parts.

[0129] Based on the above-mentioned embodiment in which the first protective cover 106a is disposed between the transparent cover plate 109a and the first platform 103, and the protective layer 109c is covered on the bending area 101b, please refer to Fig.10 , Fig.10 The display module 10 provided in some embodiments of the present application is Figure 3 The cross-sectional view at the BB line in the middle. The first adhesive material 1031 can also be provided between the first platform 103 and the protective layer 109c. That is, the first platform 103 and the protective layer 109c are connected by the first adhesive material 1031. The advantages of providing the first protective cover 106a between the transparent cover plate 109a and the first platform 103, and providing the first adhesive material 1031 between the first platform 103 and the protective layer 109c have been described in detail above and will not be repeated here.

[0130] In some embodiments of this application, please refer to Fig.11 , Fig.11 The display module 10 provided in some embodiments of the present application is Figure 3 In the cross-sectional view at the middle BB line, a lifting member 105 is provided on the side of the second non-bending area 101c away from the support structure 102, and the display module 10 further includes a second protective cover 106b, which is provided between the lifting member 105 and the first platform 103, and the second protective cover 106b is provided on the side of the bending area 101b away from the support structure 102. Specifically, one end of the second protective cover 106b is connected to the lifting member 105, and the other end of the second protective cover 106b is connected to the first platform 103. That is, the second protective cover 106b is supported on the side of the bending area 101b away from the support structure 102 by being connected to the lifting member 105 and the first platform 103 respectively.

[0131] In this way, not only the first platform 103 can protect the bending area 101b, but the second protective cover 106b can also protect the bending area 101b. In addition, the second protective cover 106b can cover the area between the lifting member 105 and the first platform 103. When the external force applied to the display panel 101 is directed to the area between the lifting member 105 and the first platform 103, the external force will directly act on the second protective cover 106b, and will not directly impact the bending area 101b. Therefore, the second protective cover 106b can further protect the bending area 101b from external force impact. Thereby, the problem of damage and breakage of the bending area 101b under the impact of external force can be better avoided, and the stability and reliability of the display of the display panel 101 can be improved. At the same time, the bending area 101b will not be deformed due to the pressure of external force, thereby ensuring that the assembly of the whole machine is not affected.

[0132] In addition, by providing the lifting member 105 and supporting the second protective cover 106b between the lifting member 105 and the first platform 103, the lifting member 105 has a lifting effect on the second protective cover 106b. By adjusting the height of the lifting member 105 along the Z-axis direction, the distance between the second protective cover 106b and the bending area 101b can be adjusted.

[0133] For example, please refer to Fig.11 By adjusting the height of the lifting member 105 along the Z-axis direction, the second protective cover 106b can be spaced apart from the bending zone 101b, thereby avoiding direct contact between the second protective cover 106b and the bending zone 101b. In this way, when the second protective cover 106b is impacted by an external force, the second protective cover 106b will not directly transfer the impact force to the bending zone 101b, thereby better reducing the risk of damage to the bending zone 101b caused by the external force impact. In some other examples, by adjusting the height of the lifting member 105 along the Z-axis direction, the second protective cover 106b can also be in direct contact with the bending zone 101b.

[0134] Optionally, the second protective cover 106b is a Mayler piece, that is, the second protective cover 106b is made of Mayler material. In this way, the second protective cover 106b has good flexibility, and when it is subjected to external impact, the second protective cover 106b can undergo elastic deformation, thereby weakening the impact force transmitted to the lifting member 105 and the first platform 103. That is, by making the second protective cover 106b a Mayler piece, the second protective cover 106b has a better buffering effect. Of course, the present application is not limited to this. In some other examples, the second protective cover 106b can also be made of PET material or PI material; in some other examples, the second protective cover 106b can also be a steel sheet made of spring steel, etc.

[0135] In addition, the shape and size of the second protective cover 106b are similar to those of the first protective cover 106a described above, and are not described in detail here.

[0136] In some embodiments of this application, please continue to refer to Fig.11 , the display module 10 further includes a third connection portion 108c, and the second protective cover 106b is connected to the lifting member 105 through the third connection portion 108c. Specifically, the third connection portion 108c is connected to the lifting member 105, and the second protective cover 106b is connected to the third connection portion 108c. Based on this, the connection between the second protective cover 106b and the lifting member 105 is more flexible, and the shape selection range of the second protective cover 106b is wider.

[0137] Specifically, in order to ensure the reliability of the connection with the lifting member 105, it is sufficient to ensure that the shape of the third connecting portion 108c is adapted to the connection structure between it and the lifting member 105, and the shape of the second protective cover 106b may not be limited by the connection requirements. Fig.11 , the third connection portion 108c can be formed into a flat plate, and the second protective cover 106b can be formed into an arc-shaped plate structure. Of course, the present application is not limited thereto. In some other examples, the third connection portion 108c and the second protective cover 106b can also have the same shape. For example, the third connection portion 108c and the second protective cover 106b can both be arc-shaped plate structures.

[0138] For further information, please refer to Fig.11 , the third connection portion 108c and the lifting member 105 are connected together by the fifth adhesive material 1051. That is to say, the third connection portion 108c and the lifting member 105 are connected together by gluing. The connection method is simple, easy to operate, and has good connection reliability. The fifth adhesive material 1051 can be arbitrarily selected as needed. For example, the fifth adhesive material 1051 can be PU adhesive or PSA adhesive. In some other examples, the third connection portion 108c and the lifting member 105 can also be connected by welding, threaded connection, or clamping.

[0139] Similarly, the position where the third connecting portion 108c is connected to the lifting member 105 can be arbitrarily selected as needed. For example, please continue to refer to Fig.11 The third connection portion 108 c may be connected to a surface of the lifting member 105 away from the display panel 101 .

[0140] Optionally, the third connection portion 108c and the second protective cover 106b may be an integrally formed part. This not only improves the connection strength between the third connection portion 108c and the second protective cover 106b, but also eliminates the connection step between the third connection portion 108c and the second protective cover 106b, thus simplifying the assembly process. In some other examples, the third connection portion 108c and the second protective cover 106b may also be separate structural parts.

[0141] In addition, the connection method between the lifting member 105 and the second non-bending area 101c can be arbitrarily selected according to needs. Fig.11 , a sixth adhesive material 1052 is provided between the lifting member 105 and the second non-bending area 101c, that is, the lifting member 105 and the second non-bending area 101c are connected by gluing. The connection method is simple, easy to operate, and has high connection reliability. The sixth adhesive material 1052 can be selected arbitrarily according to needs. For example, the fourth adhesive material 1032 can be PU adhesive or PSA adhesive. In some other examples, the lifting member 105 and the second non-bending area 101c can also be connected by welding, threaded connection, or clamping connection.

[0142] For further information, please refer to Fig.11 , the display module 10 further includes the first connection portion 108a in the above embodiment, and the second protective cover 106b is connected to the first platform 103 through the first connection portion 108a. Specifically, the first connection portion 108a is connected to the first platform 103, and the second protective cover 106b is connected between the lifting member 105 and the first connection portion 108a. Based on this, the connection between the second protective cover 106b and the first platform 103 is more flexible, and the shape selection range of the second protective cover 106b is wider.

[0143] Optionally, the first connection portion 108a and the second protective cover 106b may be an integrally formed part. In some other examples, the first connection portion 108a and the second protective cover 106b may also be separate structural parts.

[0144] In some embodiments of this application, please continue to refer to Fig.11 , the lifting member 105 can be formed into a block structure. Exemplarily, the lifting member 105 can be a block structure or a rectangular block structure. Of course, the present application is not limited thereto, and the shape of the lifting member 105 can be arbitrarily selected as needed. In some other examples, the lifting member 105 can also be a spherical structure, a spherical segment structure, or an ellipsoidal structure.

[0145] Furthermore, the material of the lifting member 105 can also be selected as needed. For example, the lifting member 105 can be made of PET material or PI material. Since PET material and PI material have the characteristics of low density and light specific gravity, by making the lifting member 105 made of PET material or PI material, the weight of the lifting member 105 is light and the cost is low, thereby reducing the overall weight and cost of the display module 10.

[0146] In addition, PET material and PI material also have good elasticity and toughness. By making the lifting member 105 made of PET material or PI material, the lifting member 105 also has good elasticity, so that the lifting member 105 has a buffering effect between the second protective cover 106b and the second non-bending area 101c. When the second protective cover 106b is impacted by an external force, when the second protective cover 106b transmits the impact force to the lifting member 105, the lifting member 105 weakens the impact force through its elastic deformation, so the impact force transmitted to the display panel 101 is further weakened, and the risk of damage to the display panel 101 can be further reduced.

[0147] In some other embodiments of the present application, the display module 10 may not include the above-mentioned lifting member 105, that is, the lifting member 105 is no longer set on the side of the second non-bending area 101c away from the supporting structure 102, and the second protective cover 106b is directly set between the second non-bending area 101c and the first platform 103.

[0148] Based on this, the third connection portion 108c is directly connected to the second non-bending area 101c. The fifth adhesive material 1051 can be directly disposed between the second non-bending area 101c and the third connection portion 108c. That is, the third connection portion 108c can be directly connected to the second non-bending area 101c through the fifth adhesive material 1051.

[0149] Based on the above-mentioned embodiment in which the second protective cover 106b is disposed between the lifting member 105 and the first platform 103, and the protective layer 109c is covered on the bending area 101b, please refer to Fig.12 , Fig.12 The display module 10 provided in some embodiments of the present application is Figure 3 The cross-sectional view at the middle BB line. The first adhesive material 1031 can also be provided between the first platform 103 and the protective layer 109c. That is, the first platform 103 and the protective layer 109c are connected by the first adhesive material 1031. The advantages of providing the second protective cover 106b between the lifting member 105 and the first platform 103, covering the protective layer 109c on the bending area 101b, and providing the first adhesive material 1031 between the first platform 103 and the protective layer 109c have been described in detail above and will not be repeated here.

[0150] In some embodiments of this application, please refer to Fig.13 , Fig.13 The display module 10 provided in some embodiments of the present application is Figure 3 The cross-sectional view at the middle line BB shows that in this embodiment, the display module 10 includes both the first protective cover 106a and the second protective cover 106b described in the above embodiment.

[0151] In this way, the first protective cover 106a can cover the area between the first platform 103 and the transparent cover plate 109a. When the external force applied to the display panel 101 is directed to the area between the first platform 103 and the transparent cover plate 109a, the external force will directly act on the first protective cover 106a without directly impacting the bending area 101b between the first platform 103 and the transparent cover plate 109a. The second protective cover 106b can cover the area between the lifting member 105 and the first platform 103. When the external force acting on the display panel 101 is directed to the area between the lifting member 105 and the first platform 103, the external force will directly act on the second protective cover 106b, and will not directly impact the bending zone 101b between the lifting member 105 and the first platform 103; when the external force acting on the display panel 101 is directed to the area where the first platform 103 is located, the external force will directly act on the first platform 103, and will not directly impact the bending zone 101b opposite to the first platform 103.

[0152] From the above, by setting the first protective cover 106a and the second protective cover 106b, and combining with the first platform 103, the first protective cover 106a, the second protective cover 106b and the first platform 103 can completely cover the bending area 101b, thereby achieving all-round protection for the bending area 101b and achieving better protection effect.

[0153] For further information, please refer to Fig.13 The display module 10 further includes the first connection portion 108a, the second connection portion 108b and the third connection portion 108c, wherein the first connection portion 108a is connected to the first platform 103, the second connection portion 108b is connected to the light-transmitting cover plate 109a, and the third connection portion 108c is connected to the lifting member 105. The first protective cover 106a is connected between the first connection portion 108a and the second connection portion 108b, and the second protective cover 106b is connected between the first connection portion 108a and the third connection portion 108c.

[0154] By providing the first connection portion 108a and connecting the first connection portion 108a to the first platform 103, not only the connection between the first protective cover 106a, the second protective cover 106b and the first platform 103 can be achieved, but also the first protective cover 106a and the second protective cover 106b can be connected together. Other advantages of providing the first connection portion 108a, and the advantages of providing the second connection portion 108b and the third connection portion 108c have been described in detail in the above embodiment, and will not be repeated here.

[0155] Preferably, the first protective cover 106a, the first connecting portion 108a and the second protective cover 106b are an integrally formed part. In other words, the first protective cover 106a, the first connecting portion 108a and the second protective cover 106b are manufactured by integral processing. This not only makes the connection strength between the first protective cover 106a and the first connecting portion 108a, and between the second protective cover 106b and the first connecting portion 108a high and not prone to breakage, but also can save the connection process between the first protective cover 106a and the first connecting portion 108a and the connection process between the second protective cover 106b and the first connecting portion 108a, thereby simplifying the assembly process.

[0156] Of course, the present application is not limited thereto, in some other examples, the first protective cover 106a, the first connecting portion 108a and the second protective cover 106b may also be separate structural parts, that is, the first protective cover 106a, the first connecting portion 108a and the second protective cover 106b are separately formed, and then the first protective cover 106a, the second protective cover 106b and the first connecting portion 108a are connected together. This can simplify the production mold.

[0157] Based on the above embodiment in which the first protective cover 106a and the second protective cover 106b are provided at the same time, and the protective layer 109c is covered on the bending area 101b, please refer to Fig.14 , Fig.14 The display module 10 provided in some embodiments of the present application is Figure 3 The cross-sectional view at the middle BB line. The first adhesive material 1031 can also be provided between the first platform 103 and the protective layer 109c. That is, the first platform 103 and the protective layer 109c are connected by the first adhesive material 1031. The advantages of simultaneously providing the first protective cover 106a and the second protective cover 106b, covering the protective layer 109c on the bending area 101b, and providing the first adhesive material 1031 between the first platform 103 and the protective layer 109c have been described in detail above and will not be repeated here.

[0158] In some embodiments of this application, please refer to Fig.15 , Fig.15 for Figure 6-Figure 14103, the display module 10 further includes a connecting arm 107. One end of the connecting arm 107 is connected to the support structure 102, and the other end of the connecting arm 107 extends toward the first platform 103 and is connected to the first platform 103. In other words, the support structure 102 and the first platform 103 are connected by the connecting arm 107, and the connection structure is simple and the connection is convenient.

[0159] For further information, please refer to Fig.15 The connecting arm 107 includes a first connecting arm 1071 and a second connecting arm 1072 which are spaced apart from each other. The first connecting arm 1071 and the second connecting arm 1072 are respectively connected to the two ends of the first platform 103. An escape opening 107a is defined between the first connecting arm 1071, the second connecting arm 1072, the first platform 103 and the supporting structure 102. The bending area 101b is disposed in the escape opening 107a. Specifically, in this embodiment, the connecting arm 107 may include two first connecting arms 1071 and a second connecting arm 1072. The first platform 103 has a first end 103a and a second end 103b along the X direction. The first connecting arm 1071 is connected between the first end 103a and the supporting structure 102, and the second connecting arm 1072 is connected between the second end 103b and the supporting structure 102.

[0160] In this way, the first end 103a of the first platform 103 is connected to the support structure 102 through the first connecting arm 1071, and the second end 103b of the first platform 103 is connected to the support structure 102 through the second connecting arm 1072. In other words, both ends of the first platform 103 along the X direction are connected to the support structure 102, thereby making the connection between the first platform 103 and the support structure 102 more balanced, more stable and reliable, and the first platform 103 is not easy to shake or break with the support structure 102 when impacted by external force.

[0161] In addition, an avoidance opening 107a is defined between the first connecting arm 1071, the second connecting arm 1072, the first platform 103 and the support structure 102, and the bending area 101b is arranged in the avoidance opening 107a. In other words, when the display panel 101 is PadBending, the bending area 101b can pass through the avoidance opening 107a, so that the first non-bending area 101a and the second non-bending area 101c are respectively located on both sides of the support structure 102. In this way, the first connecting arm 1071 and the second connecting arm 1072 will not interfere with the bending area 101b and affect the PadBending process of the display panel 101 while enhancing the connection balance and stability between the first platform 103 and the support structure 102.

[0162] It is understandable that the extension length L1 of the first platform 103 along the X-axis and the extension length L2 of the support structure 102 along the X-axis can be arbitrarily selected as needed. Fig.15 , the extension length L1 of the first platform 103 along the X-axis is less than the extension length L2 of the support structure 102 along the X-axis. Fig.16 , Fig.16 This is a front view of the connection relationship between the support structure 102 and the first platform 103 provided in some other embodiments of the present application. The extension length L1 of the first platform 103 along the X-axis is substantially equal to the extension length L2 of the support structure 102 along the X-axis. Fig.17 , Fig.17 This is a front view of the connection relationship between the support structure 102 and the first platform 103 provided in some other embodiments of the present application. The extension length L1 of the first platform 103 along the X-axis is greater than the extension length L2 of the support structure 102 along the X-axis.

[0163] In addition, the shape of the connecting arm 107 can also be arbitrarily selected according to needs. Figure 15-17 , the connecting arm 107 may be in the shape of a straight strip. Figure 15-16 , the extending direction of the connecting arm 107 and the extending direction of the first platform 103 may be perpendicular to each other; or, refer to Fig.17 The connecting arm 107 may also be extended obliquely relative to the extension direction of the first platform 103. In some other examples, the connecting arm 107 may also be formed into an arc-shaped strip, a curved strip, or a bent strip.

[0164] Similarly, the shape of the first platform 103 can also be selected as needed. Figure 15-17 , the first platform 103 is formed into a straight strip shape. In some other examples, the first platform 103 can also be formed into an arc strip shape, a curved strip shape or a bent strip shape.

[0165] In some other embodiments of the present application, the number of the connecting arm 107 may be only one. Exemplarily, the connecting arm 107 may include only the first connecting arm 1071 or only the second connecting arm 1072.

[0166] In some embodiments of the present application, the support structure 102, the first platform 103 and the connecting arm 107 are all made of metal. In other words, the support structure 102, the first platform 103 and the connecting arm 107 are all made of metal. Since the structural rigidity of metal materials is high, by making the support structure 102, the first platform 103 and the connecting arm 107 all made of metal, the first platform 103 can be stably supported on the side of the bending area 101b away from the support structure 102. When impacted by external force, the first platform 103 is not easy to shake or break with the support structure 102.

[0167] In addition, the support structure 102 is used not only to connect and support the first platform 103, but also to support the display panel 101. By making the support structure 102 made of metal, the strength and thickness of the support structure 102 can be taken into account, thereby improving the overall strength of the display module 10 while reducing the overall thickness of the display module 10, which is conducive to realizing a light and thin design of the display device 100. At the same time, by making the support structure 102 made of metal, the support structure 102 can have better heat dissipation characteristics, thereby improving the heat dissipation effect of the display panel 101.

[0168] On this basis, the support structure 102 can be grounded. Specifically, a grounding point is provided on the display device 100, and the support structure 102 is electrically connected to the grounding point. In some embodiments, the grounding point can be provided in the housing 20. Exemplarily, the grounding point can be provided on the middle plate 23 of the display device 100, or on the circuit board 30 of the display device 100. In this way, the electrostatic charge can be released through the support structure 102, thereby reducing the interference of the electrostatic charge on the electronic circuit of the display panel 101.

[0169] Furthermore, the materials of the support structure 102, the first platform 103 and the connecting arm 107 are all titanium, titanium alloy, copper, copper alloy, silver or silver alloy. In this way, not only the structural rigidity of the support structure 102, the first platform 103 and the connecting arm 107 is high, but also the heat dissipation and electrical conductivity of the support structure 102 are better. Of course, the present application is not limited to this. In some other examples, the support structure 102, the first platform 103 and the connecting arm 107 can also be a steel structure, etc.

[0170] In some other embodiments, the support structure 102, the first platform 103 and the connecting arm 107 may also be made of non-metallic materials. For example, the support structure 102, the first platform 103 and the connecting arm 107 may also be made of graphite or titanium fiber.

[0171] In some embodiments of the present application, the support structure 102, the connecting arm 107 and the first platform 103 are an integrally formed part. In other words, the support structure 102, the connecting arm 107 and the first platform 103 are manufactured by integral processing. Exemplarily, the support structure 102, the connecting arm 107 and the first platform 103 can be integrally processed by etching process, impact process or injection molding process. In this way, not only the connection strength between the support structure 102 and the connecting arm 107, and between the connecting arm 107 and the first platform 103 is high and not prone to breakage, but also the connection steps between the support structure 102 and the connecting arm 107, and between the connecting arm 107 and the first platform 103 can be omitted, simplifying the assembly process.

[0172] In other embodiments of the present application, the support structure 102, the connecting arm 107 and the first platform 103 can also be split structural parts. That is, after the support structure 102, the connecting arm 107 and the first platform 103 are formed separately, the support structure 102 and the connecting arm 107, and the connecting arm 107 and the first platform 103 are connected accordingly. Exemplarily, the support structure 102 and the connecting arm 107, and the connecting arm 107 and the first platform 103 can be connected together by welding or gluing. By making the support structure 102, the connecting arm 107 and the first platform 103 also split structural parts, the production mold can be simplified and the production method can be more diversified.

[0173] On this basis, the materials of the support structure 102, the connecting arm 107 and the first platform 103 may be different. In this way, the material selection of the support structure 102, the connecting arm 107 and the first platform 103 is more flexible. Exemplarily, the material of the support structure 102 may be titanium, and the material of the connecting arm 107 and the first platform 103 may be steel. In this way, the production cost can be reduced while taking into account the thickness, heat dissipation, conductivity and other characteristics of the display panel 101.

[0174] In some embodiments of this application, please refer to Fig.18 , Fig.18 The display module 10 provided in some embodiments of the present application is Figure 3In the cross-sectional view at the middle BB line, the display module 10 further includes a second platform 104, the second platform 104 is connected to the support structure 102, and the second platform 104 is located between the bending area 101b and the support structure 102. That is, in this embodiment, the display module 10 not only includes the first platform 103 located at the side of the bending area 101b away from the support structure 102 in the above-mentioned embodiment, but also includes the second platform 104 located at the side of the bending area 101b facing the support structure 102. The second platform 104 is also connected to the support structure 102, that is, the second platform 104 is also supported on the side of the bending area 101b facing the support structure 102 by being connected to the support structure 102.

[0175] By setting a second platform 104 on the side of the bending zone 101b facing the support structure 102, when the bending zone 101b is deformed by external force, the second platform 104 can abut against the bending zone 101b, thereby controlling the degree of deformation of the bending zone 101b and preventing the bending zone 101b from undergoing a large deformation under external force impact, thereby reducing the risk of pad bending peeling or cracking of the bending zone 101b.

[0176] Optionally, the second platform 104 and the bending area 101b can be connected together, so that the bending area 101b can be supported on the second platform 104, and when the bending area 101b is impacted by external force, the second platform 104 can prevent the bending area 101b from deforming, thereby better fixing the bending shape of the bending area 101b.

[0177] The connection method between the second platform 104 and the bending area 101b can be selected arbitrarily according to needs. Fig.19 , Fig.19 The display module 10 provided in some embodiments of the present application is Figure 3 In the cross-sectional view at the middle BB line, a second adhesive material 1041 is provided between the second platform 104 and the bending area 101b, and the second platform 104 and the bending area 101b are connected by the second adhesive material 1041. In other words, the second platform 104 and the bending area 101b can be connected together by gluing. The connection method is simple and easy to operate, and the connection between the second platform 104 and the bending area 101b is firm and has high reliability.

[0178] Optionally, the second adhesive material 1041 can be UV adhesive, thermosetting adhesive or hot melt adhesive, so that the second adhesive material 1041 has elasticity after curing. In this way, the second adhesive material 1041 can not only play the role of connecting the bending area 101b and the second platform 104 together, but also has a buffering effect between the bending area 101b and the second platform 104. In this way, a rigid collision between the bending area 101b and the second platform 104 can be avoided, which causes the bending area 101b to be damaged. Of course, the present application is not limited to this, and the second adhesive material 1041 can be arbitrarily selected as needed. In some other examples, the second adhesive material 1041 can also be PU adhesive or PSA adhesive, etc.

[0179] See also Fig. 20 , Fig. 20 for Figure 18-19 A front view of the connection relationship between the support structure 102, the connecting arm 107, the first platform 103 and the second platform 104 shown in FIG. Fig. 20 The embodiments shown in FIG. 1 and described above are similar to those shown in FIG. Fig.15 The difference between the embodiment shown in the figure is that a second platform 104 is further connected between the first connecting arm 1071 and the second connecting arm 1072. Specifically, the second platform 104 has a third end 104a and a fourth end 104b along the X direction, the third end 104a is connected to the first connecting arm 1071, and the fourth end 104b is connected to the second connecting arm 1072. The second platform 104 is located between the first platform 103 and the supporting structure 102, and the second platform 104 and the first platform 103 are spaced apart from each other. The avoidance opening 107a described in the above embodiment is formed between the first platform 103, the second platform 104, the first connecting arm 1071 and the second connecting arm 1072, and the bending area 101b can pass through the avoidance opening 107a.

[0180] That is to say, the connection arm 107 can not only realize the connection between the first platform 103 and the supporting structure 102, but also realize the connection between the second platform 104 and the supporting structure 102. The connection structure is simple and the production and processing are convenient.

[0181] In addition, the shape, size, material and the forming method between the second platform 104 and the support structure 102 and the connecting arm 107 are similar to the shape, size, material and the forming method between the first platform 103 described above, and will not be repeated here.

[0182] In some embodiments of this application, please refer to Fig.19The display module 10 further includes a cushioning layer 109b, the cushioning layer 109b is located between the first non-bending area 101a and the second non-bending area 101c, and the cushioning layer 109b and the support structure 102 are stacked. Fig.19 , the padding layer 109b may be located between the support structure 102 and the second non-bending area 101c. In some other examples, the padding layer 109b may also be disposed between the support structure 102 and the first non-bending area 101a.

[0183] The padding layer 109b also plays a supporting role between the first non-bending area 101a and the second non-bending area 101c, ensuring the spacing between the first non-bending area 101a and the second non-bending area 101c, thereby ensuring the bending radius of the bending area 101b. The thickness of the support structure 102 can be reduced by providing the padding layer 109b.

[0184] The material of the cushioning layer 109b can be selected as needed. For example, the cushioning layer 109b can be a foam layer, so that the cushioning layer 109b can also have a buffering and shock-resistant effect, and can buffer the stress acting on the display panel 101 to prevent the display panel 101 from being damaged by external forces. In some other examples, the cushioning layer 109b can be a PET material or a PI material.

[0185] In some embodiments of this application, please continue to refer to Fig.19 The display module 10 further includes a back film 109d, which is disposed on a side of the substrate away from the display layer and is attached to the substrate. The back film 109d supports the display panel 101, can enhance the structural strength of the display panel 101, and facilitates transportation and sales. The material of the back film 109d can be a flexible material, and for example, the back film 109d can be a PET material.

[0186] For further information, please refer to Fig.19 , the back film 109d is broken at the position corresponding to the bending area 101b, so as to divide the back film 109d into a first back film 109d1 and a second back film 109d2, wherein the first back film 109d1 is located between the first non-bending area 101a and the support structure 102, and the second back film 109d2 is located between the second non-bending area 101c and the padding layer 109b. It can be understood that due to the bending stress, the film layer in the bending area 101b of the display panel 101 is prone to cracks and film peeling. By breaking the back film 109d at the position corresponding to the bending area 101b, the bending characteristics of the substrate in the bending area 101b can be improved, the bending stress can be reduced, and the occurrence of cracks and film peeling can be reduced.

[0187] On the basis of the above, please continue to refer to Fig.19A first adhesive layer 109f is provided between the first backing film 109d1 and the supporting structure 102, and the first backing film 109d1 and the supporting structure 102 are connected through the first adhesive layer 109f. Exemplarily, the first adhesive layer 109f is an optically clear adhesive (OCA) layer. Of course, the present application is not limited thereto, and in some other examples, the first adhesive layer 109f can also be a pressure-sensitive adhesive layer.

[0188] In some embodiments of this application, please continue to refer to Fig.19 The display module 10 further includes a polarizing layer 109e, which is disposed between the transparent cover plate 109a and the display panel 101. The polarizing layer 109e may include a polarizer (POL), also known as a polarizing light sheet, which is used to control the polarization direction of the light beam, that is, when natural light passes through the polarizer, the light whose vibration direction is perpendicular to the transmission axis of the polarizer will be absorbed, and only the polarized light whose vibration direction is parallel to the transmission axis of the polarizer will be left.

[0189] Since there are many reflective structures inside the display panel 101, the external ambient light will be reflected by these reflective structures after entering the display panel 101 from the light-emitting surface of the display panel 101. These reflected lights are mixed with the effective light emitted by the display layer and emitted together, which will interfere with the image to be displayed. Therefore, by arranging a polarizing layer 109e between the transparent cover plate 109a and the display panel 101, the reflection of the ambient light by the display panel 101 can be reduced, and the display effect of the display panel 101 can be improved.

[0190] For further information, please refer to Fig.19 A second adhesive layer 109g is provided between the polarizing layer 109e and the transparent cover plate 109a, and the polarizing layer 109e and the transparent cover plate 109a are connected through the second adhesive layer 109g. Exemplarily, the second adhesive layer 109g is an optically clear adhesive (OCA) layer. Optical adhesive is a double-sided bonding tape without a matrix material, which has the characteristics of colorless transparency, high light transmittance (for example, total light transmittance>99%), high adhesion, high temperature resistance, UV resistance, etc., and has a controlled thickness, can provide uniform spacing, and will not cause yellowing, peeling and deterioration problems after long-term use. Therefore, by making the second adhesive layer 109g an optical adhesive layer, it can be ensured that the display effect of the display module 10 is not affected.
