It should be understood that those skilled in the art will recognize that this application can be made without using these specific details.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0035] Please see Figure 1 Currently, display devices generally have a support component between their backplate 1 and diffuser plate 2 to maintain a certain distance between the LEDs on the backplate 1 and the diffuser plate 2, thus ensuring sufficient light mixing distance. However, the length of the current support component is a specific length determined according to the light mixing distance, resulting in poor versatility of the support component and high manufacturing cost of the display device. That is, the length of the existing support component 3 is not adjustable, so the support component is manufactured separately for backlight modules with different spacing between the backplate 1 and the diffuser plate 2.
[0036] Please see Figures 2 to 5 In response, this application provides a support component including a first support member 10, a second support member 20, and an adjustment structure 30; the second support member 20 forms a socket 21 with an open end, the socket 21 being used to engage with the first support member 10; the adjustment structure 30 is disposed between the first support member 10 and the second support member 20, and is used to adjust the engagement depth between the socket 21 and the first support member 10.
[0037] In this embodiment, the support assembly includes a first support member 10, a second support assembly, and an adjustment structure 30. The adjustment structure 30 can adjust the fitting depth between the socket cavity 21 and the first support member 10, thereby adjusting the overall height of the first support member 10 and the second support member 20 when fitted together. This allows the support assembly to support backplates 40 and diffuser plates 50 with different spacings, thus improving the versatility of the support assembly. This eliminates the need for separate molds to manufacture support components for backlight modules 100 with different spacings of backplates 40 and diffuser plates 50, reducing product costs.
[0038] It is understood that the fitting depth between the socket 21 and the first support member 10 determines the total length of the first support member 10 and the second support member 20 after fitting together. The deeper the fitting depth between the socket 21 and the first support member 10, the smaller the overall height of the first support member 10 and the second support member 20 when fitted together. Conversely, the shallower the fitting depth between the socket 21 and the first support member 10, the greater the overall height of the first support member 10 and the second support member 20 when fitted together.
[0039] It should be noted that the specific implementation of the adjustment structure 30 is not limited. It can be in the form of multiple magnetic suction components. For example, multiple first magnetic suction components can be spaced apart along the length of the first support component 10, and a second magnetic suction component can be placed in the socket cavity 21. The first and second magnetic suction components have opposite magnetic properties, so that the second magnetic suction component can be selected to magnetically attract first magnetic suction components of different heights to adjust the total height of the first support component 10 and the second support component 20 after being socketed. Of course, elastic components can also be provided in the first support component 10 and the second support component 20 to allow the first support component 10 and the second support component 20 to move relative to each other. In addition, a positioning structure can be provided so that the second support component 20 can be suspended at some specific heights relative to the first support component 10, etc. There are no limitations here, as long as the second support component 20 can be suspended at different heights of the first support component 10. The light mixing distance (OD distance) is an important parameter in the design of direct-lit modules. It refers to the distance between the diffuser plate 50 and the upper surface of the PCB. The mixing distance directly affects the mixing effect and visual effect of the LED 60 light beam. Generally speaking, the larger the mixing distance, the more fully the LED 60 light beam mixes, the less shadow the LEDs cast, and the better the visual effect.
[0040] Of course, in practical use, when the distance between the back plate 40 and the diffuser plate 50 is large, the first support member 10 and the second support member 20 can provide joint support. Please refer to the following for more details. Figure 3 In some embodiments, the distance between the back plate 40 and the diffuser plate 50 is small, or the back plate 40 and the diffuser plate 50 may be supported only by the first support member 10, etc., which are not limited here.
[0041] Furthermore, in some embodiments, the adjustment structure 30 includes a plurality of connecting portions 31 and at least one mating portion 32 spaced apart along the depth direction of the sleeve cavity 21. One of the plurality of connecting portions 31 and the at least one mating portion 32 is disposed on the first support member 10, and the other is disposed on the second support member 20. The mating portion 32 is used to engage with one of the connecting portions 31 when the sleeve cavity 21 is sleeved onto the first support member 10, so as to fix the first support member 10 and the second support member 20.
[0042] In the technical solution of this embodiment, the multiple connecting parts 31 are spaced apart along the depth direction of the sleeve cavity 21. Therefore, when the mating part 32 is connected and mated with different connecting parts 31, the total height formed by the combination of the first support member 10 and the second support member 20 is different, thereby realizing the adjustment of the total height after the first support member 10 and the second support member 20 are sleeved.
[0043] It should be noted that one of the plurality of connecting parts 31 and the at least one mating part 32 is disposed on the first support member 10 and the other is disposed on the second support member 20. It is possible that the plurality of connecting parts 31 are disposed on the first support member 10 and the at least one mating part 32 is disposed on the second support member 20, or the plurality of connecting parts 31 are disposed on the second support member 20 and the at least one mating part 32 is disposed on the first support member 10. It is not limited here. The specific implementation form of the connecting parts 31 and the mating parts 32 is not limited. It can be in the form of magnetic attraction, or in the form of buckle and slot, etc. It is not limited here.
[0044] Considering the poor stability of magnetic attraction, in one embodiment, one of the connecting part 31 and the mating part 32 includes a buckle and the other includes a slot. With this arrangement, the snap-fit mating method is more stable than the magnetic attraction method, and the snap-fit method is also easier to assemble the first support member 10 and the second support member 20.
[0045] Furthermore, the spacing between any two adjacent connecting portions 31 may be equal or unequal, and is not limited here.
[0046] It is understandable that when the mating part 32 is connected to the previous connecting part 31, the total length of the first support member 10 and the second support member 20 after being sleeved will increase by the distance between the two connecting parts 31. When the distance between two adjacent connecting parts 31 is not equal, it is difficult for the installer to calculate the changed total length. Therefore, in one embodiment, the multiple connecting parts 31 are arranged at equal intervals in the depth direction of the sleeve cavity 21, so as to facilitate the installer to calculate the adjusted total length.
[0047] Furthermore, the spacing between two adjacent connecting parts 31 is not limited, as long as it is greater than 0 and less than the total length of the support member. It is understood that if the spacing between two adjacent connecting parts 31 is too large, the number of connecting parts 31 cannot be set too many, and the length range after the first support member 10 and the second support member 20 are connected will be relatively small, thus the spacing that can be adapted will also be relatively small, which will weaken the versatility of the support component.
[0048] In some embodiments, the distance between two adjacent connecting parts 31 is x, 0mm < x ≤ 3mm. In the technical solution of this embodiment, x is less than or equal to 3mm, which can provide a sufficient number of connecting parts 31 to increase the number of length positions after the first support member 10 and the second support member 20 are connected, and to adapt to backlight modules 100 with more OD distances.
[0049] In addition, in some embodiments, the plurality of connecting portions 31 are disposed on the first support member 10, and the first support member 10 is provided with a scale along the depth direction of the socket cavity 21, so that by setting the scale, the user can easily calculate the total length of the first support member 10 and the second support member 20 after adjustment.
[0050] The scale is set on the first support member 10, which is easier for the user to observe than the scale is set on the second support member 20. Furthermore, the scale is set close to the plurality of connecting parts 31. With this setting, the user can see the scale more intuitively when connecting the connecting parts 31 and the mating parts 32, which is convenient for the user to calculate.
[0051] More specifically, the scale value corresponding to each connecting part 31 is the total height of the first support member 10 and the second support member 20 when the mating part 32 is connected and mated with the connecting part 31. This setting allows the user to quickly adjust the total height of the first support member 10 and the second support member 20 to the desired height value.
[0052] At this time, the adjustment structure 30 may be provided with only one set or with multiple sets; no limitation is made here. Please refer to the relevant section for details. Figure 2 , Figure 4 and Figure 5 In one embodiment, the adjustment structure 30 is provided in multiple sets at circumferential intervals along the first support member 10, thereby enabling the adjustment and limiting of the first support member 10 and the second support member 20 through the adjustment structure 30, which preferentially increases the stability of the adjustment.
[0053] More specifically, when the adjustment structure 30 includes a connecting part 31 and a mating part 32, the second support member 20 can be suspended at the desired height through the connection and cooperation of multiple connecting parts 31 and multiple mating parts 32. Compared with the scheme of connecting a single connecting part 31 and mating part 32, its stability is obviously higher.
[0054] Considering that the first support member 10 can be used alone to support the back plate 40 and the diffuser plate 50, the height of the first support member 10 cannot be too large. For example, if it is greater than 10mm, it cannot be used for some backlight modules 100 with small OD distance. On the other hand, the height of the first support member 10 cannot be too small. For example, if it is less than 1mm, it cannot support the backlight module 100 alone.
[0055] In some embodiments, the height of the first support member 10 is a, where 1mm≤a≤10mm. Correspondingly, in the scheme of this embodiment, by setting the height of the first support member 10 to 1mm~10mm, the first support member 10 can support a portion of the backlight module 100 individually.
[0056] The specific shape of the first support member 10 and / or the second support member 20 is not limited; it can be triangular, cylindrical, frustum-shaped, etc., and is not limited here.
[0057] In one embodiment, the shape of the first support member 10 is either a frustum or a cylinder.
[0058] When the first support member 10 is frustum-shaped, the two ends of the first support member 10 along its length direction are shaped with one end having a large area and the other end having a small area. The end with the large area can be installed on the back plate 40 to improve the stability of the first support member 10, while the other end with a small area can reduce the overall material used of the first support member 10 and reduce the manufacturing cost.
[0059] When the first support member 10 is cylindrical, it can adapt to situations where the number of LED lights is relatively dense, similar to a shadowless lamp, and provides better support between the diffuser plate 50 and the back plate 40.
[0060] Alternatively, the first support member 10 can have a triangular cross-section along its thickness direction, that is, the first support member 10 can be in the shape of a thickened triangular plate. In this case, the first support member 10 requires the least amount of material and has the best transparency.
[0061] The material of the first support member 10 and / or the second support member 20 is not limited; it can be acrylic, plastic, metal, etc., and is not limited here.
[0062] In one embodiment, the first support member 10 and / or the second support member 20 are plastic parts, which can be easily molded and manufactured and reduce production costs.
