Description

Technical Field

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

[0002] With the development of display technology, the demand for and application range of display devices are constantly expanding. Commonly used display devices include mobile phones, televisions, tablets, laptops, and monitors. The appearance of display devices strives for higher screen-to-body ratios and ultra-thin bezel designs to ensure a superior visual experience.

[0003] A display device typically includes a display module and a mid-frame. The display module has a display area and a non-display area located around the display area, and the mid-frame is connected to the non-display area to protect the display module from the sides.

[0004] However, due to the structural limitations of the non-display area at the bottom of the display area, the bottom bezel of the display area is quite wide, which affects the user experience. Utility Model Content

[0005] This application provides a display module and display device that can solve the problem of a large bottom bezel width caused by the structural limitations of the non-display area at the bottom of the display area. The technical solution is as follows:

[0006] On the one hand, a display module is provided, including: a display panel and multiple functional film layers;

[0007] The display panel includes: a first panel portion and a second panel portion disposed opposite to each other, and a panel bending portion for connecting the first panel portion and the second panel portion, wherein the first panel portion has a display area;

[0008] The plurality of functional film layers are stacked between the first panel portion and the second panel portion;

[0009] The panel bending portion includes a first connecting segment, an intermediate connecting segment, and a second connecting segment connected in sequence; the first connecting segment is parallel to the first panel portion, and one end of the first connecting segment away from the intermediate connecting segment is connected to the first panel portion; the second connecting segment is parallel to the second panel portion, and one end of the second connecting segment away from the intermediate connecting segment is connected to the second panel portion; the intermediate connecting segment is in contact with at least one layer of the functional film layer.

[0010] The display module provided in this application includes a display panel and multiple functional film layers. The middle connecting segment in the display panel is in contact with the side of at least one functional film layer. On the one hand, this reduces or even eliminates the gap between the middle connecting segment and the functional film layer, making the middle connecting segment fit tightly against the functional film layer. This reduces the width of the non-display area at the bottom of the display panel and the width of the bottom bezel of the display device, which is beneficial for achieving an optimal narrow bezel design. On the other hand, the functional film layer can also provide stable support for the middle connecting segment, prevent deformation of the middle connecting segment, and improve the structural stability of the middle connecting segment.

[0011] In some possible implementations, the functional film layer closest to the first panel portion among the plurality of functional film layers is the first support layer. The first support layer is connected to the side of the first panel portion facing the second panel portion, and the side of the first support layer facing the intermediate connecting segment is in contact with the intermediate connecting segment.

[0012] The first support layer is also connected to the side of the first connecting segment facing the second connecting segment, meaning the first support layer simultaneously supports both the first panel and the first connecting segment. Furthermore, the intermediate connecting segment contacts the side of the first support layer, reducing or even eliminating the gap between the intermediate connecting segment and the functional film layer, allowing the intermediate connecting segment to fit snugly against the functional film layer and reducing the width of the bottom bezel of the display device.

[0013] In some possible implementations, the functional film layer closest to the second panel portion among the plurality of functional film layers is the second support layer. The second support layer is connected to the side of the second panel portion facing the first panel portion, and the side of the second support layer facing the intermediate connecting segment is in contact with the intermediate connecting segment.

[0014] The second connecting segment is connected to the second support layer on the side facing the first connecting segment. That is, the second support layer is used to support both the second panel and the second connecting segment. The side of the second support layer contacts the middle connecting segment, which can reduce or even eliminate the gap between the middle connecting segment and the functional film layer, so that the middle connecting segment is in close contact with the functional film layer, thereby reducing the width of the bottom bezel of the display device.

[0015] In some possible implementations, the side of the first support layer facing the intermediate connecting segment is flush with the side of the second support layer facing the intermediate connecting segment;

[0016] The plane containing the intermediate connecting segment is perpendicular to the plane containing the first connecting segment and also perpendicular to the plane containing the second connecting segment.

[0017] This design avoids the problem of a large width of the non-display area at the bottom of the display panel due to the middle connecting section protruding outwards towards the side away from the functional film layer, thereby reducing the width of the bottom bezel of the display device.

[0018] In some possible implementations, the side of the first support layer facing the intermediate connecting segment protrudes beyond the side of the second support layer facing the intermediate connecting segment;

[0019] The intermediate connecting section includes: a first transition section, a main body section, and a second transition section connected together, wherein the end of the first transition section opposite to the main body section is connected to the first connecting section, and the end of the second transition section opposite to the main body section is connected to the second connecting section;

[0020] The angle between the plane containing the main body segment and the plane containing the first connecting segment is an acute angle, and the angle between the main body segment and the plane containing the second connecting segment is an obtuse angle.

[0021] In this way, the first support layer protrudes from the side facing the middle connecting section, and the second support layer also protrudes from the side facing the middle connecting section. That is, without affecting the first support layer providing sufficient support to the first panel, the second support layer is recessed relative to the first support layer. This increases the gap between the second support layer and the side plate, preventing damage to the middle connecting section located on the second support layer due to deformation and squeezing of the side plate.

[0022] In some possible implementations, the angle between the plane containing the first transition segment and the plane containing the main body segment is an obtuse angle, and the angle between the plane containing the second transition segment and the plane containing the main body segment is an obtuse angle.

[0023] The angle between the plane containing the first transition segment and the plane containing the first connecting segment is a right angle, and the angle between the plane containing the second transition segment and the plane containing the second connecting segment is an obtuse angle.

[0024] Specifically, the angle between the plane containing the first transition section and the plane containing the first connecting section is a right angle. Compared to an acute angle, the right angle results in a larger radius of curvature, leading to greater stress dispersion between the first transition section and the first connecting section. This significantly reduces the risk of stress concentration and improves the bending reliability between the two sections. Similarly, the angle between the plane containing the second transition section and the plane containing the second connecting section is an obtuse angle. Obtuse angles result in less concentrated stress compared to right angles, which also contributes to improved bending reliability between the second transition section and the second connecting section.

[0025] In some possible implementations, the second support layer has a first slope on the side facing the intermediate connecting segment, and the first slope is in contact with the second transition segment.

[0026] This increases the distance between the first inclined surface and the side plate, preventing damage to the second transition section on the first inclined surface caused by deformation and compression of the side plate.

[0027] In some possible implementations, the functional film layer connected to the side of the second support layer near the first support layer among the plurality of functional film layers is a padding layer, the padding layer having a second inclined surface on the side facing the intermediate connecting section, and the second inclined surface fitting with the second transition section.

[0028] In this way, the second slope fits into the second transition section to prevent the middle second transition section from bulging outward and to reduce the width of the bottom frame; at the same time, it increases the distance between the second slope and the side plate to prevent the second transition section on the second slope from being damaged due to deformation and squeezing of the side plate.

[0029] In some possible implementations, the first inclined plane and the second inclined plane are coplanar.

[0030] This design allows the second transition section to fit against both the first and second inclined surfaces simultaneously, reducing the bending of the second transition section.

[0031] In some possible implementations, at least a portion of the panel bending section has a stress-relieving structure. This stress-relieving structure disperses the stress during bending of the panel bending section, preventing excessive stress concentration and thus ensuring the panel is not easily damaged during bending.

[0032] In some possible implementations, the interior of the panel bend has an organic layer and metal traces; the stress relief structure includes: a plurality of grooves distributed on the organic layer and / or a plurality of openings distributed on the metal traces.

[0033] In this way, the grooves on the organic layer can reduce the deformation of the panel when bending. Similarly, the openings in the metal wires can disperse stress and reduce the risk of the metal wires breaking due to bending, while not significantly affecting their conductivity, thereby improving the bending reliability and service life of the panel.

[0034] In some possible implementations, the display module further includes a protective adhesive layer covering the bent portion of the panel, at least a portion of which is located on the side of the bent portion of the panel away from the plurality of functional film layers.

[0035] With this configuration, the protective adhesive layer covers the side of the panel bend that is away from the multiple functional film layers, in order to protect the panel bend and ensure that the protective adhesive layer bears the impact force after the panel bend is subjected to impact, thereby reducing the probability of the panel bend being broken.

[0036] On the other hand, a display device is provided, including: a middle frame and a display module, wherein the middle frame is connected to the display module.

[0037] In some possible implementations, the mid-frame includes: a base plate, and side plates connected to the edge of the base plate; at least a portion of the display module is located within the area enclosed by the side plates;

[0038] The side of the side panel facing the bent portion of the panel is in contact with the protective adhesive layer provided on the bent portion of the panel.

[0039] In this way, the protective adhesive layer protects the bent part of the panel. On this basis, the side panel is in direct contact with the protective adhesive layer, which can further reduce the width of the bottom bezel.

[0040] In some possible implementations, the intermediate connecting segment sequentially includes: a first transition segment connected to the first connecting segment, a second transition segment connected to the second connecting segment, and a main body segment connected between the first connecting segment and the second connecting segment; if the angle between the plane where the main body segment is located and the plane where the first connecting segment is located is acute, and the angle between the main body segment and the plane where the second connecting segment is located is obtuse, the display device further includes: a filling colloid, the filling colloid filling the space enclosed by the second transition segment, the side plate, and the bottom plate.

[0041] Thus, by filling the space enclosed by the second transition section, the side plate and the bottom plate with the filler colloid, it serves two purposes: firstly, to connect the second transition section to the side plate and the bottom plate respectively, and secondly, to buffer and protect the second transition section, preventing damage to the second transition section caused by deformation of the side plate due to external impact forces.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0053] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a display device provided by related technology. The display module may include: a frame 010, a display panel 020, and a driver chip 080. The frame 010 at least surrounds the periphery of the display panel 020. The display panel 020 may include: a first panel portion 021, a second panel portion 022, and a panel bending portion 023 for connecting the first panel portion 021 and the second panel portion 022. It should be noted that signal traces are integrated in the first panel portion 021, the second panel portion 022, and the panel bending portion 023, and the signal traces in the panel bending portion 023 can connect the signal traces in the first panel portion 021 and the signal traces in the second panel portion 022. The driver chip 080 is bonded to the side of the second panel portion 022 opposite to the first panel portion 021, and the driver chip 080 can be electrically connected to the signal lines in the second panel portion 022. In this way, the driver chip 080 can send driving signals to the sub-pixels in the first panel 021 through these signal lines, so that the sub-pixels in the first panel 021 can emit light outward, thereby enabling the first panel 021 to display the corresponding image.

[0054] Among them, multiple functional film layers 070 can be provided between the first panel portion 021 and the second panel portion 022. The panel bending portion 023 can be a semi-circular or elliptical structure, that is, the panel bending portion 023 protrudes outward toward the side away from the multiple functional film layers 070. In other words, the functional film layers 070 and the panel bending portion 023 are spaced apart, thereby making the width of the non-display area at the bottom of the display panel 020 larger, which in turn leads to a larger bottom bezel width of the display device.

[0055] See Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of a display module provided in an embodiment of this application. Figure 3 This is a schematic diagram of a display device provided in an embodiment of this application. The display module includes a display panel 100 and multiple functional film layers 200. The display panel 100 includes a first panel portion 110 and a second panel portion 120 disposed opposite to each other, and a panel bending portion 130 for connecting the first panel portion 110 and the second panel portion 120. The first panel portion 110 has a display area, and a driving chip is disposed on the side of the second panel portion 120 opposite to the first panel portion 110. The driving chip is electrically connected to the second panel portion 120 to drive the display area of ​​the first panel portion 110 to display a corresponding image through the second panel portion 120 and the panel bending portion 130.

[0056] Multiple functional film layers 200 are stacked between the first panel portion 110 and the second panel portion 120, and the functional film layers 200 at least have the function of supporting the first panel portion 110 and the second panel portion 120.

[0057] The panel bending portion 130 includes a first connecting segment 131, an intermediate connecting segment 132, and a second connecting segment 133 connected in sequence. The first connecting segment 131 is parallel to the first panel portion 110, and one end of the first connecting segment 131 opposite to the intermediate connecting segment 132 is connected to the first panel portion 110. The second connecting segment 133 is parallel to the second panel portion 120, and one end of the second connecting segment 133 opposite to the intermediate connecting segment 132 is connected to the second panel portion 120. This ensures effective contact between the first connecting segment 131 and the second connecting segment 133 and the functional film layer 200, allowing one surface of the functional film layer 200 to simultaneously support the first panel portion 110 and the first connecting segment 131, and another surface to simultaneously support the second panel portion 120 and the second connecting segment 133.

[0058] The first panel portion 110 is located on the front side of the display panel 100, and the second panel portion 120 is located on the back side of the display panel 100. One end of the intermediate connecting segment 132 is connected to the first panel portion 110, and the other end is connected to the second panel portion 120, that is, the intermediate connecting segment 132 is located on the side of the display panel 100. Furthermore, the intermediate connecting segment 132 is in contact with the side of at least one functional film layer 200. See also... Figure 3 This can reduce or even eliminate the gap between the intermediate connecting section 132 and the functional film layer 200, so that the intermediate connecting section 132 is in close contact with the functional film layer 200, thereby reducing the width of the non-display area at the bottom of the display panel 100 and reducing the width of the bottom bezel of the display device; on the other hand, the functional film layer 200 can also provide stable support for the intermediate connecting section 132 and improve the structural stability of the intermediate connecting section 132.

[0059] In summary, the display module provided in this application includes a display panel and multiple functional film layers. The middle connecting segment in the display panel is in contact with the side of at least one functional film layer. On the one hand, this reduces or even eliminates the gap between the middle connecting segment and the functional film layer, allowing the middle connecting segment to be in close contact with the functional film layer. This reduces the width of the non-display area at the bottom of the display panel and the width of the bottom bezel of the display device, which is beneficial for achieving an optimal narrow bezel design. On the other hand, the functional film layer can also provide stable support for the middle connecting segment, prevent deformation of the middle connecting segment, and improve the structural stability of the middle connecting segment.

[0060] It should be noted that the display panel 100 is a flexible display panel 100, and therefore can be bent according to the usage. The first panel portion 110, the second panel portion 120, and the panel bending portion 130 can be formed by bending a single display panel 100. That is, a portion of the display panel 100 is connected to the front side of the functional film layer 200, and another portion is bent from the side to the back side of the functional film layer 200, thereby realizing the first panel portion 110, the second panel portion 120, and the panel bending portion 130. To facilitate the bending of the panel bending portion 130, the panel bending portion 130 can be thinned, for example, by eliminating the encapsulation layer of the panel bending portion 130.

[0061] In some possible embodiments, the functional film layer 200 closest to the first panel portion 110 among the multiple functional film layers 200 is the first support layer 210. The first support layer 210 is connected to the side of the first panel portion 110 facing the second panel portion 120, and the side of the first support layer 210 facing the intermediate connecting segment 132 contacts the intermediate connecting segment 132.

[0062] The first support layer 210 is also connected to the side of the first connecting segment 131 facing the second connecting segment 133, meaning the first support layer 210 simultaneously supports the first panel portion 110 and the first connecting segment 131. Furthermore, the intermediate connecting segment 132 contacts the side of the first support layer 210, reducing or even eliminating the gap between the intermediate connecting segment 132 and the functional film layer 200, allowing the intermediate connecting segment 132 to fit tightly against the functional film layer 200 and reducing the width of the bottom bezel of the display device.

[0063] For example, the first support layer 210 may be a polymeric polyester support layer.

[0064] In some possible embodiments, the functional film layer 200 closest to the second panel portion 120 among the multiple functional film layers 200 is the second support layer 220. The second support layer 220 is connected to the side of the second panel portion 120 facing the first panel portion 110, and the side of the second support layer 220 facing the intermediate connecting segment 132 contacts the intermediate connecting segment 132.

[0065] The second connecting segment 133 is connected to the second support layer 220 on the side facing the first connecting segment 131. That is, the second support layer 220 is used to support both the second panel portion 120 and the second connecting segment 133. The side of the second support layer 220 contacts the middle connecting segment 132, which can reduce or even eliminate the gap between the middle connecting segment 132 and the functional film layer 200, so that the middle connecting segment 132 is in close contact with the functional film layer 200, thereby reducing the width of the bottom bezel of the display device.

[0066] For example, the second support layer 220 may be a polymeric polyester support layer.

[0067] In one possible embodiment, see Figures 2-4 , Figure 4 yes Figure 2 A schematic diagram of the bending section of the middle panel. The side of the first support layer 210 facing the middle connecting section 132 is flush with the side of the second support layer 220 facing the middle connecting section 132; wherein, the plane where the middle connecting section 132 is located is perpendicular to the plane where the first connecting section 131 is located, and is also perpendicular to the plane where the second connecting section 133 is located.

[0068] The intermediate connecting segment 132 includes: a first transition segment 132a, a main body segment 132b, and a second transition segment 132c, which are connected end-to-end and coplanar. The plane of the first transition segment 132a is perpendicular to the plane of the first connecting segment 131 and is connected to the first connecting segment 131. The plane of the second transition segment 132c is perpendicular to the plane of the second connecting segment 133 and is connected to the second connecting segment 133. This arrangement avoids the problem of a large width of the non-display area at the bottom of the display panel 100 due to the intermediate connecting segment 132 protruding outward toward the side opposite to the functional film layer 200, thereby reducing the width of the bottom bezel of the display device.

[0069] In another possible embodiment, see [reference] Figure 5 , Figure 5 This is a schematic diagram of a display module according to another embodiment of this application. The side of the first support layer 210 facing the intermediate connecting section 132 protrudes from the side of the second support layer 220 facing the intermediate connecting section 132. In other words, the second support layer 220 is recessed relative to the first support layer 210. When the side plates 420 of the middle frame 400 are provided around the periphery of the display panel 100, the gap between the second support layer 220 and the side plates 420 can be increased, preventing damage to the intermediate connecting section 132 located on the second support layer 220 due to deformation and compression of the side plates 420.

[0070] See Figures 5-7 , Figure 6 This is a schematic diagram of the structure of a display device provided in another embodiment of this application; Figure 7 yes Figure 5 A schematic diagram of the bending section of the middle panel. The intermediate connecting segment 132 includes: a first transition segment 132a, a main segment 132b, and a second transition segment 132c connected together. The end of the first transition segment 132a facing away from the main segment 132b is connected to the first connecting segment 131, and the end of the second transition segment 132c facing away from the main segment 132b is connected to the second connecting segment 133. The first transition segment 132a, the main segment 132b, and the second transition segment 132c may be on the same plane or on different planes.

[0071] The main body segment 132b is tilted relative to the display surface of the display panel 100, resulting in an acute angle between the plane of the main body segment 132b and the plane of the first connecting segment 131, and an obtuse angle between the main body segment 132b and the plane of the second connecting segment 133. This ensures that the side of the first support layer 210 protrudes towards the middle connecting segment 132 and the side of the second support layer 220 also protrudes towards the middle connecting segment 132. That is, without affecting the first support layer 210 providing sufficient support to the first panel portion 110, the second support layer 220 is recessed relative to the first support layer 210. This increases the gap between the second support layer 220 and the side plate 420, preventing damage to the middle connecting segment 132 located on the second support layer 220 due to deformation and compression of the side plate 420.

[0072] In one of the first possible embodiments, see Figures 5-7 The angle between the plane containing the first transition segment 132a and the plane containing the main body segment 132b is an obtuse angle, and the angle between the plane containing the second transition segment 132c and the plane containing the main body segment 132b is also an obtuse angle. The angle between the plane containing the first transition segment 132a and the plane containing the first connecting segment 131 is a right angle, and the angle between the plane containing the second transition segment 132c and the plane containing the second connecting segment 133 is an obtuse angle. It should be emphasized that all the above angles are angles on the side of the intermediate connecting segment 130 closest to the functional membrane layer 200.

[0073] In this embodiment, the panel bending portion 130 of the display panel 100 is in a deformed state for a long time. The angle between the first transition section 132a and the first connecting section 131 directly affects the stress distribution in this area. The angle between the plane containing the first transition section 132a and the plane containing the first connecting section 131 is a right angle. Compared to an acute angle, the right angle results in a larger bending radius, leading to more dispersed stress between the first transition section 132a and the first connecting section 131, significantly reducing the risk of stress concentration and improving the bending reliability between them. Similarly, the angle between the plane containing the second transition section 132c and the plane containing the second connecting section 133 is an obtuse angle. The concentrated stress at an obtuse angle is smaller than that at a right angle, which is beneficial for improving the bending reliability between the second transition section 132c and the second connecting section 133.

[0074] In one possible embodiment, the second support layer 220 has a first inclined surface 221 on the side facing the intermediate connecting segment 132, and the first inclined surface 221 is in contact with the second transition segment 132c.

[0075] The second transition section 132c is fitted to the first inclined surface 221 to prevent the middle second transition section 132c from bulging outward and to reduce the width of the bottom frame. Furthermore, along the direction towards the middle connecting section 132, the side of the second support layer 220 closest to the first support layer 210 extends to the side of the second support layer 220 away from the first support layer 210. This makes the angle between the side of the second support layer 220 near the middle connecting section 132 and the surface of the second support layer 220 away from the first support layer 210 an obtuse angle. Consequently, when the second transition section 132c is fitted to the first inclined surface 221, the angle between the plane containing the second transition section 132c and the plane containing the second connecting section 133 is also an obtuse angle. This increases the distance between the first inclined surface 221 and the side plate 420, preventing damage to the second transition section 132c located on the first inclined surface 221 due to deformation and compression of the side plate 420.

[0076] In one possible embodiment, among the multiple functional membrane layers 200, the functional membrane layer 200 connected to the side of the second support layer 220 near the first support layer 210 is a padding layer 230. The padding layer 230 has a second inclined surface 231 on the side facing the intermediate connecting section 132, and the second inclined surface 231 is in contact with the second transition section 132c.

[0077] The padding layer 230 is used to increase the distance between the first panel portion 110 and the second panel portion 120. Along the direction towards the intermediate connecting section 132, the side of the padding layer 230 near the first support layer 210 protrudes from the side of the padding layer 230 near the second support layer 220, so that the padding layer 230 has a second inclined surface 231 on the side facing the intermediate connecting section 132. The second inclined surface 231 fits with the second transition section 132c to prevent the intermediate second transition section 132c from protruding outward, reducing the width of the bottom bezel, which is beneficial to achieving an optimal narrow bezel design; at the same time, it increases the distance between the second inclined surface 231 and the side plate 420 to prevent the second transition section 132c located on the second inclined surface 231 from being damaged due to deformation and compression of the side plate 420.

[0078] In one possible embodiment, the first inclined surface 221 and the second inclined surface 231 are coplanar, so that the second transition section 132c can simultaneously fit with the first inclined surface 221 and the second inclined surface 231, thereby reducing the bending of the second transition section 132c.

[0079] In one of the first possible embodiments, see Figure 5Among the multiple functional film layers 200, the functional film layer 200 located between the first support layer 210 and the padding layer 230 is a buffer heat dissipation layer 240. The side of the buffer heat dissipation layer 240 facing the intermediate connecting section 132 is a plane, and the side of the first support layer 210 facing the intermediate connecting section 132 extends to the outside of the buffer heat dissipation layer 240 facing the intermediate connecting section 132. The surface of the padding layer 230 near the first support layer 210 is flush with the buffer heat dissipation layer 240.

[0080] The heat dissipation buffer layer 240 is bonded to both the first support layer 210 and the padding layer 230. The heat dissipation buffer layer 240 dissipates heat generated by the driver chip. This effectively reduces the operating temperature of the driver chip, preventing the signal traces electrically connected to the driver chip within the display panel 100 from being burned, thereby improving the display effect of the display panel 100. Simultaneously, the heat dissipation buffer layer 240 also provides support and cushioning for the driver chip bonded to the second panel portion 120, ensuring that the driver chip is protected from damage by the buffer layer 240 when subjected to external forces.

[0081] For example, the buffer heat dissipation layer 240 includes a buffer layer and a conductive layer stacked together, with the buffer layer located on the side of the conductive layer close to the first support layer 210. For example, the buffer layer may be a foam layer, and the conductive layer may be a copper layer.

[0082] In one of the second possible embodiments, see Figure 8 , Figure 8 This is a schematic diagram of the structure of a display module provided in another embodiment of this application. Among the multiple functional film layers 200, the functional film layer 200 located between the first support layer 210 and the padding layer 230 is a buffer heat dissipation layer 240. The buffer heat dissipation layer 240 has a third inclined surface 241 on the side facing the intermediate connecting section 132, and the third inclined surface 241 is attached to the main body section 132b.

[0083] This design can further increase the gap between the buffer heat dissipation layer 240 and the side plate 420, thereby preventing the main body section 132b located on the third inclined surface 241 from being damaged due to deformation and squeezing of the side plate 420.

[0084] For example, the first inclined plane 221, the second inclined plane 231 and the third inclined plane 241 are coplanar, which can make the main body segment 132b and the second transition segment 132c coplanar, so as to reduce the bending of the intermediate connecting segment 132.

[0085] In one of the third possible embodiments, see Figure 9 , Figure 9This is a schematic diagram of the structure of a display module provided in another embodiment of this application. The first support layer 210 has a fourth inclined surface 211 on the side facing the intermediate connecting section 132, and the fourth inclined surface 211 is in contact with the first transition section 132a.

[0086] This design further increases the gap between the buffer heat dissipation layer 240 and the side plate 420, thereby preventing the side plate 420 from deforming and being squeezed, which could lead to damage to the first transition section 132a on the fourth inclined surface 211. It also helps to reduce the thickness of the side plate 420.

[0087] For example, the first inclined plane 221, the second inclined plane 231, the third inclined plane 241 and the fourth inclined plane 211 are coplanar, which can make the first transition segment 132a, the main body segment 132b and the second transition segment 132c coplanar, so as to reduce the bending of the intermediate connecting segment 132.

[0088] At least a portion of the panel's bending section has a stress-relieving structure. This stress-relieving structure disperses the stress during bending, preventing excessive stress concentration and thus protecting the panel from damage during bending.

[0089] The interior of the panel bending section has an organic layer and metal traces; the stress relief structure includes: multiple grooves distributed on the organic layer and / or multiple openings distributed on the metal traces.

[0090] The stress relief structure may include multiple grooves distributed on the organic layer, or multiple openings distributed on the metal traces. Alternatively, the stress relief structure may include multiple grooves distributed on the organic layer and multiple openings distributed on the metal traces.

[0091] The grooves in the organic layer can reduce the deformation of the panel when bending. Similarly, the openings in the metal wires can disperse stress and reduce the risk of the metal wires breaking due to bending, without significantly affecting their conductivity, thereby improving the bending reliability and service life of the panel.

[0092] See Figure 5 The display module also includes a protective adhesive layer 140 covering the panel bend 130, at least a portion of which is located on the side of the panel bend 130 away from the plurality of functional film layers 200.

[0093] With this configuration, the protective adhesive layer 140 covers the side of the panel bend 130 that is away from the multiple functional film layers 200, and is used to protect the panel bend 130. This ensures that the protective adhesive layer 140 bears the impact force after the panel bend 130 is subjected to an impact, thereby reducing the probability that the panel bend 130 will be broken.

[0094] In some possible embodiments, the display module further includes a protective cover plate 600 and an optical layer 500. The optical layer 500 is disposed on the side of the display panel 100 opposite to the first support layer 210. The protective cover plate 600 is connected to the side of the optical layer 500 opposite to the display panel 100, and the protective cover plate 600 covers the display panel 100 to protect it. For example, the optical layer 500 may include a polarizer.

[0095] In summary, the display module provided in this application includes a display panel and multiple functional film layers. The middle connecting segment in the display panel is in contact with the side of at least one functional film layer. On the one hand, this reduces or even eliminates the gap between the middle connecting segment and the functional film layer, allowing the middle connecting segment to be in close contact with the functional film layer. This reduces the width of the non-display area at the bottom of the display panel and the width of the bottom bezel of the display device, which is beneficial for achieving an optimal narrow bezel design. On the other hand, the functional film layer can also provide stable support for the middle connecting segment, prevent deformation of the middle connecting segment, and improve the structural stability of the middle connecting segment.

[0096] This application also provides a display device, which can be any product or component with display function, such as a mobile phone, tablet computer, television, advertising machine, display screen, digital photo frame, or vehicle terminal. The display device may include a mid-frame 400 and a display module, wherein the display module is any of the display modules described in the above embodiments, and the mid-frame 400 is connected to the display module.

[0097] See Figure 6 The middle frame 400 includes: a base plate 410 and a side plate 420 connected to the edge of the base plate 410; at least a portion of the display module is located in the area enclosed by the side plate 420; wherein the side plate 420 is in contact with the protective adhesive layer 140 disposed on the panel bending portion 130 on the side facing the panel bending portion 130.

[0098] The protective adhesive layer 140 protects the bent portion 130 of the panel. Furthermore, the side panel 420 directly contacts the protective adhesive layer 140, which can further reduce the width of the bottom bezel. For example, the protective adhesive layer is UV adhesive.

[0099] In some possible embodiments, the intermediate connecting segment 132 sequentially includes: a first transition segment 132a connected to the first connecting segment 131, a second transition segment 132c connected to the second connecting segment 133, and a main body segment 132b connected between the first connecting segment 131 and the second connecting segment 133; when the angle between the plane where the main body segment 132b is located and the plane where the first connecting segment 131 is located is an acute angle, and the angle between the main body segment 132b and the plane where the second connecting segment 133 is located is an obtuse angle, the display device further includes: a filling colloid 430, the filling colloid 430 filling the space enclosed by the second transition segment 132c, the side plate 420 and the bottom plate 410.

[0100] Thus, the display module in this embodiment can be Figures 5-9 The display module is filled with a filling colloid 430 in the space enclosed by the second transition section 132c, the side plate 420 and the bottom plate 410. This serves two purposes: firstly, to connect the second transition section 132c to the side plate 420 and the bottom plate 410 respectively; and secondly, to buffer and protect the second transition section 132c, preventing damage to the second transition section 132c caused by deformation of the side plate 420 due to external impact forces.

Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.
