Description

Connector and backlight module

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 29, 2023, with application number 202311295436.3 and application name “A connector, backlight module, display panel and display device”, the entire contents of which are incorporated by reference into this application.

[0059] The following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of this application, and not all of them. All other embodiments derived by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0060] The backlight module is one of the key components of the display panel, used to illuminate the display panel so that it can display images normally.

[0061] In related art, a backlight module typically includes a backplane, light-emitting devices, and a diffuser. The light-emitting devices are mounted on the backplane, and the diffuser is positioned on the light-emitting side of the light-emitting devices. This allows the light emitted by the light-emitting devices to be diffused more evenly by the diffuser. To prevent the diffuser from collapsing toward the light-emitting devices, the backplane is typically equipped with a lamp support that abuts the diffuser to provide support.

[0062] However, in actual use, the diffusion plate is likely to bulge outward in a direction away from the light-emitting device, thereby affecting the display effect of the display device.

[0063] Please refer to Figure 1, which is a schematic diagram of the first structure of the backlight module provided in an embodiment of the present application. Based on this, an embodiment of the present application provides a connector 100, which is used in the backlight module. The connector 100 is provided with a first connecting structure 111 and a second connecting structure 121. The first connecting structure 111 is used to connect and fix to the diffuser plate 400. The second connecting structure 121 is used to connect and fix to the back plate 200. The connector 100 is deformable so that the diffuser plate 400 can be deformed in a direction closer to or away from the back plate 200.

[0064] For example, the backlight module may include a back plate 200 , a backlight source 300 , and a diffusion plate 400 . The backlight source 300 is disposed on the back plate 200 , and the diffusion plate 400 is disposed on the light-emitting side of the backlight source 300 .

[0065] Therefore, after the back panel 200 and the diffuser plate 400 are connected via the connector 100, it can be simply understood that the connector 100 fixed to the back panel 200 at least pulls the diffuser plate 400 to limit the extent to which the diffuser plate 400 bulges outward relative to the backlight source 300, thereby ensuring the display effect of the display device. It can also be understood that because at least a portion of the connector 100 located between the first connecting structure 111 and the second connector 100 structure can deform to a certain extent, when the diffuser plate 400 is subjected to external impact or thermal expansion, the diffuser plate 400 can deform a certain distance toward or away from the backlight source 300 to provide a buffer, thereby preventing damage to the diffuser plate 400, damage to the connector 100, and disconnection between the diffuser plate 400 and the connector 100, ultimately improving the reliability of the backlight module. Therefore, it can be seen that the connector 100 of the embodiment of the present application can stably and reliably pull the diffuser plate 400 to limit the extent to which the diffuser plate 400 bulges outward relative to the backlight source 300, thereby improving the display effect of the display device.

[0066] In some embodiments, the connector 100 may be deformable as a whole, so that the portion of the connector 100 located between the first connecting structure 111 and the second connecting structure 121 is also deformable. The connector 100 may also be partially deformable, for example, only the portion of the connector 100 located between the first connecting structure 100 and the second connecting structure 121 may be deformable, or all portions of the connector 100 located between the first connecting structure 100 and the second connecting structure 121 may be deformable, or all portions of the connector 100 except the first connecting structure 111 may be deformable. It is understood that as long as at least a portion of the connector 100 located between the first connecting structure 111 and the second connecting structure 121 is deformable, so that the diffuser plate 400 can be deformed in a direction closer to or away from the back plate 200, the technical solution is within the scope of protection of this application, and the embodiments of this application are not limited thereto.

[0067] In some embodiments, the connector 100 includes one of an elastic connector 100 and a flexible connector 100 .

[0068] The elastic connector 100 is a connector 100 that can be elastically deformed when subjected to an external force and can return to its original size and shape when the external force is removed. For example, the connector 100 can be made of an elastic material or have some elastic and retractable structure, which is not limited in the present embodiment.

[0069] The flexible connector 100 is a connector 100 that can deform when subjected to an external force and cannot automatically return to its original shape when the external force is removed. For example, the connector 100 can be a soft connecting wire, a flexible rod, etc., and the present embodiment does not limit this.

[0070] The above is an overall introduction and description of the connector 100 in the embodiment of the present application. The following further explains and illustrates the technical solution of the embodiment of the present application in combination with some optional structures of the first connecting structure 111.

[0071] In some embodiments, the first connection structure 111 includes a first clamping structure, and the first clamping structure is used to clamp and fix with the diffuser plate 400 .

[0072] It is understandable that the first clamping structure may be various. For example, the first clamping structure may include a first annular clamping groove, and the first annular clamping groove is used to clamp the diffuser plate 400 .

[0073] For example, please continue to refer to Figures 2 and 3. Figure 2 is a schematic structural diagram of the connector in the backlight module shown in Figure 1, and Figure 3 is a three-dimensional view of the connector in the backlight module shown in Figure 1. Connector 100 includes a shaft body, which includes a first connecting segment 11 and a second connecting segment 12 connected to each other. The first engaging structure includes a first annular engaging groove provided in the first connecting segment 11, and the second connecting structure 121 is provided in the second connecting segment 12.

[0074] Thus, the shaft can be inserted into the diffuser plate 400, so that the diffuser plate 400 is engaged in the first annular groove. In this case, the back plate 200 can provide a certain support to the diffuser plate 400 through the shaft, thereby limiting the inward concavity of the diffuser plate 400 relative to the backlight source 300. In turn, the connector 100 can simultaneously limit the inward and outward concavity of the diffuser plate 400, thereby controlling the light mixing distance of the backlight module.

[0075] In some embodiments, the second connecting section 12 is made of an elastic material, so that the portion of the connecting member 100 located between the first connecting structure 111 and the second structure can undergo elastic deformation.

[0076] At this time, at least a portion of the first connecting segment 11 and the second connecting segment 12 may be made of different materials, or the first connecting segment 11 and the second connecting segment 12 may be made of the same material, which is not limited in this embodiment of the present application.

[0077] Taking the example that at least a portion of the first connecting segment 11 and the second connecting segment 12 are made of different materials, the hardness of the end of the first connecting segment 11 away from the second connecting segment 12 may be greater than the hardness of the second connecting segment 12 .

[0078] It is understood that in a display panel, a liquid crystal structure layer, etc., is typically also provided on the side of the diffuser plate 400 facing away from the backlight source 300. To reduce the gap between the diffuser plate 400 and the liquid crystal structure layer, thereby achieving a thinner and lighter display device, the height of the connector 100 protruding from the side of the diffuser plate 400 facing away from the backlight source 300 can be less than or equal to 1.3 mm. For example, the height of the connector 100 protruding from the side of the diffuser plate 400 facing away from the backlight source 300 can be 1.3 mm, 1 mm, 0.7 mm, 0.65 mm, 0.44 mm, etc., and this embodiment of the present application is not limited thereto.

[0079] Specifically, the groove wall, which may be the first annular groove, includes a first inner sidewall 112 distal from the second connecting segment 12. The distance between the end surface of the first connecting segment 11 facing away from the second connecting segment 12 and the first inner sidewall 112 is less than or equal to 1.3 mm. For example, the distance between the end surface of the first connecting segment 11 facing away from the second connecting segment 12 and the first inner sidewall 112 may be 1.3 mm, 1 mm, 0.7 mm, 0.65 mm, 0.44 mm, or the like. Thus, the portion of the connector 100 protruding from the side of the diffuser plate 400 facing away from the backlight source 300 can be accommodated in the gap between the diffuser plate and the liquid crystal structure layer.

[0080] Based on this, it can also be understood that if the wall thickness of the first inner sidewall 112 is less than or equal to 1.3 mm, the strength of the first inner sidewall 112 will be relatively low. Therefore, setting the hardness of the first connecting segment 11 to be greater than the hardness of the second connecting segment 12 can effectively prevent the first connecting segment 11 from deforming under force, ultimately causing the diffuser plate 400 to fall out of the first annular groove.

[0081] For example, the end of the first connecting segment 11 facing away from the second connecting segment 12 may be made of a hard material, and the second connecting segment 12 may be made of an elastic material, so that the hardness of the first connecting segment 11 is greater than that of the second connecting segment 12 .

[0082] In some embodiments, the inner wall of the first annular groove includes a second inner sidewall 115 adjacent to the second connecting segment 12. The portion of the first connecting segment 11 extending from the second inner sidewall 115 to the second connecting segment 12 is made of an elastic material. Thus, during insertion of the shaft from the side of the diffuser plate 400 facing away from the backlight source 300, the end of the first connecting segment 11 adjacent to the second connecting segment 12 can adaptively deform, facilitating installation.

[0083] It can be understood that the end of the first connecting segment 11 away from the second connecting segment 12 may be made of a hard material, and the part of the first connecting segment 11 from the second inner wall 115 to the second connecting segment 12 may not be made of an elastic material; or the end of the first connecting segment 11 away from the second connecting segment 12 may not be made of a hard material, and the part of the first connecting segment 11 from the second inner wall 115 to the second connecting segment 12 may be made of an elastic material; or the end of the first connecting segment 11 away from the second connecting segment 12 may be made of a hard material, and the part of the first connecting segment 11 from the second inner wall 115 to the second connecting segment 12 may be made of an elastic material. The embodiments of the present application do not limit this.

[0084] In some embodiments, along the radial direction of the shaft, the portion of the first connecting segment 11 located in the middle of the first annular groove, facing away from the second connecting segment 12, is made of a light-transmitting material. For example, taking the case where the first connecting segment 11 is located above the second connecting segment 12, it can also be understood that the upper half of the first connecting segment 11, defined by the middle of the first annular groove, is a light-transmitting structure. This prevents the upper half of the first connecting segment 11 from obstructing the diffusion and propagation of light within the diffuser plate 400, ultimately ensuring more uniform light distribution across all locations of the backlight module.

[0085] In some embodiments, along the radial direction of the shaft, the portion of the first connecting segment 11 located in the middle of the first annular groove on the side away from the second connecting segment 12 is made of the same material as the diffuser plate 400. This makes the final light output from all parts of the backlight module more consistent, and avoids the formation of obvious dark spots or bright spots on the first connecting segment 11 of the backlight module.

[0086] In some embodiments, a second diffusion structure is built into the first connecting segment 11, located in the middle of the first annular groove and facing away from the second connecting segment 12, along the radial direction of the shaft. This makes the final light output from all parts of the backlight module more consistent, avoiding the formation of obvious dark spots or bright spots in the first connecting segment 11.

[0087] The second diffusion structure may include diffusion particles, foaming particles, etc., which is not limited in the embodiment of the present application.

[0088] In some embodiments, along the radial direction of the shaft, the portion of the first connecting segment 11 located in the middle of the first annular groove facing away from the second connecting segment 12 can be subjected to highlight treatment, so that the final light output from various parts of the backlight module is more consistent, thereby avoiding the formation of obvious dark spots or bright spots in the backlight module at the first connecting segment 11.

[0089] For example, along the radial direction of the shaft, the portion of the first connecting section 11 located in the middle of the first annular groove facing away from the second connecting section 12 can be made of transparent PC (Polycarbonate) material, PVC (Polyvinyl chloride) material, foam material, etc., which is not limited in this embodiment of the present application.

[0090] In some embodiments, along the radial direction of the shaft, the portion of the first connecting segment 11 located in the middle of the first annular groove near the second connecting segment 12 and / or the second connecting segment 12 is made of a light-transmitting material and has a built-in first diffusion structure. This makes the final light output from all parts of the backlight module more consistent, avoiding the formation of obvious dark spots or bright spots on the first connecting segment 11 of the backlight module.

[0091] The first diffusion structure may include diffusion particles, foaming particles, etc., which is not limited in the embodiment of the present application.

[0092] For example, along the radial direction of the shaft, the portion of the first connecting segment 11 located in the middle of the first annular groove close to the second connecting segment 12 and / or the second connecting segment 12 are made of transparent silicone material, rubber material, etc., which is not limited in the embodiment of the present application.

[0093] In some embodiments, along the radial direction of the shaft, the transmittance of a portion of the first connecting segment 11 located in the middle of the first annular groove facing away from the second connecting segment 12 can be greater than the transmittance of a portion of the first connecting segment 11 located in the middle of the first annular groove close to the second connecting segment 12.

[0094] In some embodiments, the portions of the first connecting segment 11 located on different sides of the first annular groove along the radial direction of the shaft can be integrally formed. For example, the portions of the first connecting segment 11 located on different sides of the first annular groove along the radial direction of the shaft can be integrally formed by two-color injection molding or 3D printing.

[0095] Optionally, the parts of the first connecting section 11 located on different sides of the first annular groove may also be detachably connected.

[0096] For example, the first connecting section 11 located on different sides of the first annular groove can be detachably connected by screwing, snapping, or sleeve connection. Therefore, in actual use, different components can be selected for assembly according to the model changes of the diffuser plate 400 or the back plate 200, thereby improving the versatility of the connector 100.

[0097] Optionally, in some embodiments, the first connecting segment 11 is made of a light-transmitting material, and the second connecting segment 12 is made of a light-reflecting material.

[0098] It is understood that since the first connecting segment 11 is disposed through the diffuser plate 400, if the first connecting segment 11 is made of a transparent material, the portion of the first connecting segment 11 disposed within the diffuser plate 400 will not block the diffusion and propagation of light within the diffuser plate 400, thereby achieving more uniform light output from all positions of the backlight module. Simultaneously, since the second connecting segment 12 is made of a reflective material, it can effectively reflect light between the backlight source 300 and the diffuser plate 400, allowing more light to enter the diffuser plate 400, thereby improving the light output efficiency of the backlight module or, in other words, increasing the brightness of the backlight module.

[0099] In some embodiments, the hardness of the first connecting segment 11 may be greater than the hardness of the second connecting segment 12, and the first connecting segment 11 may be made of a light-transmitting material. For example, the first connecting segment 11 may be made of a transparent PC (Polycarbonate) material, PVC (Polyvinyl chloride) material, etc., which is not limited in this embodiment of the present application.

[0100] Of course, the hardness of the first connecting segment 11 may be greater than the hardness of the second connecting segment 12, and the first connecting segment 11 may not be made of a light-transmitting material, or the first connecting segment 11 may be made of a light-transmitting material, and the hardness of the first connecting segment 11 may be less than or equal to the hardness of the second connecting segment 12. This embodiment of the present application does not limit this.

[0101] In some embodiments, the second connecting segment 12 may be made of an elastic material and a reflective material, or the second connecting segment 12 may be made of an elastic reflective material; for example, the second connecting segment 12 may be made of a reflective silicone material, a rubber material, etc., which is not limited in this embodiment of the present application.

[0102] Of course, the second connecting section 12 may be made of an elastic material but not a reflective material, or the first connecting section 11 may be made of a reflective material but not an elastic material, and this embodiment of the present application does not limit this.

[0103] In some embodiments, the first connecting section 11 and the second connecting section 12 are integrally formed.

[0104] For example, the first connecting section 11 and the second connecting section 12 may be integrally formed by two-color injection molding.

[0105] Optionally, the first connecting section 11 and the second connecting section 12 may also be detachably connected.

[0106] For example, the first connecting section 11 and the second connecting section 12 are detachably connected by screwing, snapping, or sleeve connection. Therefore, in actual use, different first connecting sections 11 and second connecting sections 12 can be selected for assembly according to the model changes of the diffuser plate 400 or the back plate 200, thereby improving the versatility of the connector 100.

[0107] In some embodiments, the outer wall of the first connecting section 11 includes a first guide surface 113, which is connected to the second connecting section 12, and the end of the first guide surface 113 close to the second connecting section 12 is inclined toward the axis of the shaft body.

[0108] Please continue to refer to Figure 4, which is an assembly diagram of the backlight module shown in Figure 1. When the connecting member 100 passes through a hole on the diffuser plate 400, such as the first through hole 41, from the side of the diffuser plate 400 facing away from the backlight source 300, the second connecting segment 12 can be first passed through the first through hole 41 of the diffuser plate 400, and then guided by the first guide surface 113 and the hole end face of the first through hole 41 to prevent the step surface formed by the step difference at the connection between the first connecting segment 11 and the second connecting segment 12 from being stuck on the hole end face of the first through hole 41, thereby allowing the first connecting segment 11 to be more conveniently inserted into the first through hole 41, and finally allowing the diffuser plate 400 to be stuck in the first annular groove.

[0109] In some embodiments, the outer side wall of the first connecting section 11 is further provided with a first opening 114 . The first opening 114 is communicated with the first annular groove and is located on a side of the first annular groove close to the second connecting section 12 .

[0110] Below, the technical solution of the embodiment of the present application is further explained and illustrated by taking the example of the connector 100 being installed from the side of the diffuser plate 400 facing away from the backlight source 300:

[0111] First, the diffuser plate 400 may be provided with a first through hole 41, and the second connecting section 12 is first passed through the first through hole 41; then, the first connecting section 11 is driven to partially pass through the first through hole 41. During this process, the outer wall of the first connecting section 11 is first squeezed by the diffuser plate 400 and deformed toward the first opening 114, so that the outer diameter of this part of the first connecting section 11 becomes smaller and thus passes through the first through hole 41 of the diffuser plate 400; finally, after the diffuser plate 400 is inserted into the first annular groove, the compressed and shrunken part of the first connecting section 11 is restored, so that the diffuser plate 400 is inserted into the first annular groove.

[0112] It is understandable that the outer side wall of the first connecting section 11 may be provided with only the first guide surface 113 or only the first opening 114 , and this embodiment of the present application does not limit this.

[0113] Of course, the outer wall of the first connecting section 11 may also be provided with both the first guide surface 113 and the first opening 114. For example, the first opening 114 may extend from the first annular groove to the first guide surface 113, thereby achieving a dual effect through the first opening 114 and the first guide surface 113, so as to facilitate the insertion of the diffuser plate 400 into the first groove.

[0114] In some embodiments, the inner diameter of the first annular groove is greater than or equal to the maximum outer diameter of the second connecting section 12 .

[0115] Then, during the actual assembly process, the second connecting section 12 can be conveniently passed through the through hole of the diffuser plate 400, such as the first through hole 41, and then the first connecting section 11 can be passed through the first through hole 41, so that the diffuser plate 400 is clamped in the first annular groove of the first connecting section 11, and the second connecting section 12 is connected and fixed to the back panel 200, thereby reducing the difficulty of assembling the backlight module.

[0116] Alternatively, the diffuser plate 400 may be provided with a first through hole 41 , and the first clamping structure may further include a first undercut, and the first undercut is used to be clamped to the first through hole 41 .

[0117] The first clamping structure may include one first inverted buckle, or may include multiple first inverted buckles such as two, three, four or five, which is not limited in this embodiment of the present application.

[0118] Alternatively, the first connection structure 111 may further include a first thread, so that the connection member 100 can be connected and fixed to the diffuser plate 400 by threaded connection, which is not limited in this embodiment of the present application.

[0119] The above is an illustrative description of some optional structures of the first connecting segment 11 in the embodiment of the present application. The following will continue to provide illustrative descriptions in combination with some optional structures of the second connecting segment 12.

[0120] In some embodiments, the second connection structure 121 may include a second clamping structure for clamping and fixing with the back plate 200 .

[0121] For example, the connector 100 includes a shaft. The shaft includes a first connecting section 11 and a second connecting section 12 connected axially. A first connecting structure 111 is provided on the first connecting section 11, and a second engaging structure includes a second annular engaging groove provided on the outer side wall of the second connecting section 12.

[0122] For example, the back plate 200 of the backlight module may be provided with a second through hole 21. Then, an assembly process of the embodiment of the present application may be:

[0123] First, position the diffuser plate 400 and the back panel 200; then, pass the second connecting section 12 through the first through hole of the diffuser plate 400 and partially through the back panel 200, so that the back panel 200 is snapped into the second annular slot, and the diffuser plate 400 is snapped into the first annular slot, thereby making the assembly of the backlight module easier.

[0124] In some embodiments, the outer wall of the first connecting section 11 is provided with a second guide surface 122. The second guide surface 122 is located on the side of the second annular groove away from the first connecting section 11, and the end of the second guide surface 122 away from the second annular groove is inclined toward the axis of the shaft.

[0125] It is understood that when the connector 100 is installed from the diffuser plate 400 away from the backlight source 300, the first connecting section 11 can first pass through the first through hole 41 of the diffuser plate 400 and then partially pass through the second through hole 21 of the back plate 200, so that the back plate 200 is engaged with the second annular groove and the diffuser plate 400 is engaged with the first annular groove. During this process, the second guide surface 122 can cooperate well with the end surface of the opening of the first through hole 41 and the end surface of the opening of the second through hole 21 to provide a guiding effect.

[0126] In some embodiments, the second guiding slope may be connected to an end surface of the second connecting section 12 facing away from the first connecting section 11 .

[0127] In some embodiments, the outer diameter of the second guide surface 122 away from the second annular groove is smaller than the inner diameter of the second annular groove, thereby facilitating the pre-insertion of the second guide surface 122 into the second through hole 21 of the back plate 200 .

[0128] In some embodiments, the outer side wall of the second connecting section 12 may be provided with a second opening 123 . The second opening 123 is connected to the second annular groove and is located on a side of the second annular groove away from the first connecting section 11 .

[0129] It is understood that when the connector 100 is installed from the side of the diffuser plate 400 facing away from the backlight source 300, the second connecting section 12 may first pass through the first through-hole 41 of the diffuser plate 400 and then partially pass through the second through-hole 21 of the back panel 200, thereby allowing the back panel 200 to be engaged within the second annular groove and the diffuser plate 400 to be engaged within the first annular groove. During the process of partially passing through the second through-hole 21, the outer wall of the second connecting section 12 is first squeezed by the back panel 200 and deformed toward the second opening 123, thereby reducing the outer diameter of this portion of the second connecting section 12 so that it can pass through the second through-hole 21 of the diffuser plate back panel 200. Finally, after the back panel 200 is engaged within the second annular groove, the compressed portion of the second connecting section 12 recovers, allowing the back panel 200 to be engaged within the second annular groove.

[0130] In some embodiments, the second connecting segment 12 is provided with an anti-slip structure 124 , and the anti-slip structure 124 is located on a side of the second annular groove facing away from the first connecting segment 11 .

[0131] For example, the anti-slip structure 124 may include some annular anti-slip grooves, so that after the end of the second connecting section 12 passes through the back panel 200, it is convenient for the user or the robot to hold the end of the second connecting section 12, thereby pulling the connecting member 100 from the outside of the back panel 200, so that the back panel 200 is snapped into the second annular slot and the diffuser plate 400 is snapped into the second annular slot.

[0132] In some embodiments, the anti-slip structure 124 may include an anti-slip groove surrounding an outer side wall of the second connecting segment 12 .

[0133] It can be understood that the outer side wall of the second connecting section 12 may be provided with only one of the second guide surface 122, the second opening 123 and the anti-slip structure 124, the outer side wall of the second connecting section 12 may also be provided with only two of the second guide surface 122, the second opening 123 and the anti-slip structure 124, or the outer side wall of the second connecting section 12 may also be provided with the second guide surface 122, the second opening 123 and the anti-slip structure 124 at the same time, and the embodiments of the present application do not limit this.

[0134] Taking the outer wall of the second connecting section 12 as an example, which is provided with a second guide surface 122, a second opening 123 and an anti-slip structure 124 at the same time, the second opening 123 can extend from the second annular groove to the second guide surface 122, and the anti-slip structure 124 is at least partially located on the second guide surface 122.

[0135] Please continue to refer to Figure 5, which is a schematic diagram of a second structural embodiment of a backlight module provided in an embodiment of the present application. In some embodiments, the connector 100 includes a shaft, which includes a first connecting segment 11 and a second connecting segment 12. The first engaging structure includes a first annular engaging groove provided in the first connecting segment 11, and the second engaging structure includes a second annular engaging groove provided in the second connecting segment 12; wherein the maximum outer diameter of the first connecting segment 11 is less than or equal to the inner diameter of the second annular engaging groove.

[0136] Then, the back plate 200 may be provided with a second through hole 21, the diffuser plate 400 may be provided with a first through hole 41, and the connector 100 may be inserted and installed from the side of the back plate 200 facing away from the backlight source 300. For example,

[0137] First, pass the first connecting section 11 through the second through hole 21; then, drive the first connecting section 11 partially through the second through hole 21, so that the first connecting section 11 partially passes through the diffuser plate 400, thereby clamping the diffuser plate 400 in the first annular groove, and the second connecting section 12 passes through the back plate 200, thereby clamping the back plate 200 in the second annular groove.

[0138] In some embodiments, the back plate 200 may be provided with a second through hole 21 , and the second snap-fit ​​structure may further include a second undercut, and the second undercut is used to snap into the second through hole 21 .

[0139] The second clamping structure may include one second inverted buckle, or may include multiple second inverted buckles such as two, three, four or five, which is not limited in this embodiment of the present application.

[0140] Alternatively, the second connection structure 121 may further include a second thread, so that the connector 100 can be connected and fixed to the back plate 200 by a threaded connection, which is not limited in the embodiment of the present application.

[0141] The embodiment of the present application further provides a backlight module, which may be provided with the above-mentioned connector 100 .

[0142] Exemplarily, the backlight module includes a backplate 200, a backlight source 300, a diffuser plate 400, and a connector 100. The backlight source 300 is disposed on the backplate 200. The diffuser plate 400 is disposed on the light-emitting side of the backlight source 300. The connector 100 is connected to the backplate 200 and the diffuser plate 400, respectively.

[0143] In some embodiments, the connection structure between the diffuser plate 400 and the connector 100 can refer to the matching structure between the connector 100 and the diffuser plate 400 when used in the backlight module, and will not be described in detail in the embodiments of the present application.

[0144] In some embodiments, the connection structure between the back plate 200 and the connector 100 can refer to the above-mentioned connection method of the connector 100 and the back plate 200 when used in the backlight module, and will not be described in detail in the embodiment of the present application.

[0145] 6 , which is a schematic diagram of a third structural embodiment of a backlight module provided in an embodiment of the present application. In some embodiments, when the connector 100 is a flexible connector 100 , the backlight module further includes a support member 500 , which is fixedly connected to the back panel 200 and abuts against the diffuser 400 to support the diffuser 400 .

[0146] Thus, the diffuser plate 400 can be pulled by the connector 100 installed on the back panel 200 to limit the outward bulging of the diffuser plate 400 relative to the backlight source 300, and the diffuser plate 400 can be supported by the support member 500 installed on the back panel 200 to limit the inward concavity of the diffuser plate 400 relative to the backlight source 300.

[0147] In some embodiments, the backlight module is a Mini LED (sub-millimeter light-emitting diode) backlight module or a Micro LED (micrometer light-emitting diode) backlight module, which is not limited in the embodiments of the present application.

[0148] Specifically, the backlight source 300 may include a Mini LED (sub-millimeter light emitting diode) chip or a Micro LED (micrometer light emitting diode) chip.

[0149] The present application also provides a backlight module, which may include a backplate 200, a diffuser plate 400, and a connector 100. The diffuser plate 400 is disposed on a light-emitting side of the backplate 200. The connector 100 is fixedly connected to the backplate 200 and the diffuser plate 400, respectively. The connector 100 is deformable to allow the diffuser plate 400 to deform toward or away from the backplate 200.

[0150] For example, the backlight module may further include a backlight source 300 . The backlight source 300 is disposed on the back plate 200 , and the diffusion plate is located on the light-emitting side of the backlight source 300 .

[0151] Therefore, after the back panel 200 and the diffuser plate 400 are connected via the connector 100, it can be simply understood that the connector 100 fixed to the back panel 200 at least pulls the diffuser plate 400 to limit the extent of the diffuser plate 400 protruding relative to the backlight source 300, thereby ensuring the display effect of the display device. It can also be understood that because at least a portion of the connector 100 located between the back panel 200 and the diffuser plate 400 can deform to a certain extent, when the diffuser plate 400 is subjected to external impact or thermal expansion, the diffuser plate 400 can deform a certain distance in the direction closer to or away from the backlight source 300 to provide a buffer, thereby preventing damage to the diffuser plate 400, damage to the connector 100, and disconnection between the diffuser plate 400 and the connector 100, ultimately improving the reliability of the backlight module. Therefore, it can be seen that the connector 100 of the embodiment of the present application can stably and reliably pull the diffuser plate 400 to limit the extent of the diffuser plate 400 protruding relative to the backlight source 300, thereby improving the display effect of the display device.

[0152] In some embodiments, the connection structure between the connector 100 and the diffuser plate 400 may refer to the connection structure between the diffuser plate 400 and the connector 100 in the above embodiment, which will not be described in detail in this embodiment of the present application.

[0153] Please continue to refer to Figure 7, which is a schematic diagram of the fourth structure of the backlight module provided in the embodiment of the present application. Optionally, the connecting member 100 can also be bonded and fixed to the diffusion plate 400, which is not limited in the embodiment of the present application.

[0154] In some embodiments, the connection structure between the connector 100 and the back plate 200 can refer to the connection structure between the back plate 200 and the connector 100 in the above embodiment, and will not be described in detail in the embodiment of the present application.

[0155] Optionally, the connector 100 may also be bonded and fixed to the back plate 200 , which is not limited in the embodiment of the present application.

[0156] In some embodiments, when the connector 100 is a flexible connector 100 , the backlight module further includes a support member 500 . The support member 500 is fixedly connected to the back plate 200 and abuts against the diffuser plate 400 to support the diffuser plate 400 .

[0157] Thus, the diffuser plate 400 can be pulled by the connector 100 installed on the back panel 200 to limit the outward bulging of the diffuser plate 400 relative to the backlight source 300, and the diffuser plate 400 can be supported by the support member 500 installed on the back panel 200 to limit the inward concavity of the diffuser plate 400 relative to the backlight source 300.

[0158] In some embodiments, the backlight module is a Mini LED (sub-millimeter light-emitting diode) backlight module or a Micro LED (micrometer light-emitting diode) backlight module, which is not limited in the embodiments of the present application.
