Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a backplate structure, a backlight module, and a display device. Background Technology

[0002] With the rapid development of display technology, large-size splicing display products are widely used in the market. Currently, most LED TVs on the market are no larger than 70 inches.

[0003] For large-screen TVs, that is, TVs larger than 70 inches, the problem of the back panel being prone to deformation has always been an issue that cannot be ignored. The larger the size, the more easily the back panel is deformed. Currently, the deformation of the back panel is usually prevented by adding reinforcing ribs or increasing the thickness of the panel. However, when the size is greater than 100 inches, the traditional methods of adding reinforcing ribs and increasing the thickness of the panel are obviously no longer sufficient to meet the requirements for the flatness and warping of the back panel. This would result in the back panel of the TV being too heavy and unable to be properly mounted. Utility Model Content

[0004] The main purpose of this utility model is to provide a back panel structure, a backlight module, and a display device, which aims to solve the problem of excessive weight of the back panel.

[0040] Please see Figure 1 The present invention provides a back plate structure 100, including a back plate 1 and a plurality of reinforcing plates 2; the back plate 1 has a mounting back surface, the mounting back surface having a plurality of spaced-apart bearing areas; the plurality of reinforcing plates 2 are fixedly mounted on the mounting back surface, each reinforcing plate spanning at least two of the bearing areas to support the mounting back surface.

[0041] In the backplate structure provided by this utility model, the backplate 1 has a mounting back surface with multiple spaced-apart load-bearing areas. Adjacent load-bearing areas form easily deformable sections. Multiple reinforcing plates 2 are fixedly mounted on the mounting backplate, with each reinforcing plate 2 spanning at least two load-bearing areas to provide strength support to the easily deformable sections of the backplate 1. When the backplate 1 deforms along these easily deformable sections under stress, the external force is transferred to the reinforcing plates 2 to support the backplate 1. Simultaneously, the reinforcing plates 2 control the backplate 1 to produce warping or other deformations. The structure is simple and reliable, requiring no additional reinforcing ribs or plate thickness, ensuring both structural strength and the weight of the backplate 1.

[0042] It should be noted that there are several ways to fix the reinforcing plate 2 to the back of the mounting, such as by directly welding it to the back of the mounting.

[0043] The reinforcing plate 2 can be made of various materials to ensure strength while keeping the overall weight low. In this embodiment, the reinforcing plate 2 is a metal strip, specifically an aluminum alloy strip.

[0044] Specifically, in this embodiment, the reinforcing plate 2 is riveted to the back plate 1. In this embodiment, the reinforcing plate 2 is fixed by riveting, which is a simple installation method. Furthermore, the reinforcing plate 2 can be easily added or removed according to actual needs without affecting the structural strength of the back plate 1.

[0045] On the other hand, in one embodiment of this utility model, the reinforcing plate 2 includes a first reinforcing strip 21, the two ends of which extend to two side portions adjacent to the length direction of the back plate 1. In this embodiment, the back plate 1 is relatively large and therefore more prone to deformation in the length direction. Thus, by providing the first reinforcing strip 21, the deformation of the back plate 1 in the length direction is controlled, thereby improving the structural strength of the back plate 1 in the length direction.

[0046] Similarly, multiple reinforcing plates 2 together form a reinforcing group, and multiple reinforcing groups are provided, spaced apart along the length direction of the back plate. In this embodiment, by providing multiple reinforcing groups, the structural strength of the back plate 1 is controlled along its length direction.

[0047] It should be noted that the reinforcing group can be implemented in various ways. The structural strength of the back plate 1 in a certain area can be controlled by irregularly shaped plates, or the structural strength in a certain area can be controlled by a combination of multiple plates.

[0048] In a specific embodiment of this utility model, the plurality of reinforcing groups include two side reinforcing groups located on both sides of the back plate along its length. Each side reinforcing group includes two vertical strips 22 and a horizontal strip 23. The two vertical strips 22 extend along the width direction of the back plate 1 and are spaced apart along the length direction of the back plate 1. The horizontal strip 23 extends along the length direction of the back plate 1 and is positioned between the two vertical strips 22, with both ends of the horizontal strip 23 abutting against the sides of the two vertical strips 22. In this embodiment, the two vertical strips 22 and the horizontal strip 23 form an H-shaped reinforcing structure, ensuring that the reinforcing group maintains a certain resistance to deformation in both the length and width directions, thus guaranteeing the structural safety of the back plate 1.

[0049] It should be noted that, in this embodiment, the two edge reinforcement groups are spaced apart along the length direction of the back plate 1 and are respectively arranged on the side of the back plate 1 along the length direction to reinforce the structural weaknesses on the back plate 1. The reinforcement groups are located at the edge of the back plate 1 and directly reinforce the side. Compared with the reinforcement group located in the middle of the back plate 1, the reinforcement effect is better and more material is saved, which can reduce the load weight on the back plate 1.

[0050] Furthermore, the reinforcing plate 2 also includes a second reinforcing strip 24, which extends along the length of the back plate 1 and is positioned between the two reinforcing groups. In this embodiment, a gap area is formed between the two reinforcing groups. To ensure the structural strength between the gap areas, a second reinforcing plate 24 is provided between the two reinforcing groups to structurally reinforce the areas of the back plate not covered by the reinforcing groups, thereby ensuring the structural strength of the back plate 1.

[0051] In addition, the reinforcing plate 2 also includes a mating strip 25 extending along the width direction of the back plate 1. The mating strip 25 is disposed between the two vertical strips 22, and one end of the mating strip 25 abuts against the horizontal strip 23. In this embodiment, the reinforcing group is H-shaped. To further reduce the structural safety of the gap area within the reinforcing group, the mating strip 25 is also disposed between the two vertical strips 23 and abuts against the horizontal strip 23. This can control the deformation of the horizontal strip 23, preventing it from bending due to excessive force. At the same time, it covers the gap area within the reinforcing group, further strengthening the strength of the covering structure within the reinforcing group.

[0052] Based on the aforementioned backplate structure 100, this utility model also provides a backlight module, wherein the backplate module has all the technical features of the backplate structure 100, and therefore also has the technical effects brought about by all the aforementioned technical features, which will not be elaborated here.

[0053] Please see Figure 2 The backplate 1 of the backplate structure 100 also has a front mounting side facing the mounting back; the backlight module also includes multiple splicing lamp panels 3, which are sequentially spliced ​​and installed on the front mounting side. In this embodiment, the normal light emission operation of the backlight module is achieved through the splicing lamp panels 3.

[0054] It should be noted that, in this embodiment, the splicing light panel 3 is a Mini LED light panel.

[0055] For further details, please refer to Figure 3A reflector 41 is also provided between two adjacent splicing light panels 3. Due to the large size of the backplate 1 and the splicing light panels 3, the gaps between the large-sized Mini LEDs are generally also relatively large, which greatly affects the display effect. In this embodiment, a dark gap is formed between two adjacent splicing light panels 3. The backlight module also includes a supplementary light structure 4, which is used to supplement the light in the dark gap. In this embodiment, the supplementary light structure 4 is provided in the dark gap between two splicing light panels 3 to block the gap between the light panels and supplement the light, thereby improving the optical display effect.

[0056] It should be noted that the supplementary lighting structure can be implemented in various ways. For example, a reflector can be placed directly between the two splicing light panels to reflect the light entering the dark gap to supplement the light in the dark gap.

[0057] Please participate Figure 4 Because the large-size Mini LED light panel is not heat-resistant, it is prone to deformation after emitting heat, which in turn changes the size of the dark slit. Therefore, in this embodiment, the supplementary lighting structure includes a base 41, a reflective layer 42, and a light-emitting element 43. The base 41 is located on the front side of the mounting surface corresponding to the dark slit, and a driving circuit is provided on the base. The reflective layer 42 is located on the side of the base 41 facing the splicing light panel to reflect light incident from the dark slit. The light-emitting element 43 is located on the side of the base 41 facing the splicing light panel and is electrically connected to the driving circuit to emit light under the drive of the driving circuit to supplement the light of the dark slit. In this embodiment, a base 41 is provided corresponding to the dark slit, and a reflective layer 42 and a light-emitting element 43 are simultaneously provided on the base 41. Under normal conditions, the reflective layer 42 supplements the light of the dark slit; when the size of the dark slit changes due to heat and becomes more obvious, the LED beads are driven to emit light to supplement the light of the dark slit.

[0058] It should be noted that the base can be implemented in various ways. The base can be formed by protruding ribs or by external bearing plates. In this embodiment, the base is formed by glass ribs fixed to the front side of the mounting.

[0059] In this embodiment, multiple bases 41 are provided corresponding to the dark seam. Each base 41 supports the ends of two adjacent splicing light panels 3, allowing the splicing light panels 3 to be mounted on the bases 41, so that the dark seam is located on the bases, and the reflective layer 42 and the light-emitting element 43 are located within the dark seam. In this embodiment, the reflective layer 42 and the light-emitting element 43 reflect and emit light within the dark seam to supplement the light in the dark seam.

[0060] It should be noted that the reflective layer 42 can be implemented in various ways, as long as it can reflect light, such as by attaching a reflective sheet; similarly, in this embodiment, the light-emitting element 43 can be an LED lamp bead, and no specific limitation is made here.

[0061] The beneficial effects of the above-described extended embodiments are that the supplementary lighting mode for dark seams can be selected, the assembly of the lamp board is more convenient, no additional PCB circuit board is required, and the ribs used for supplementary lighting are made of stable glass structure, which is not easily deformed by heat compared to traditional PCB circuits, thus maintaining a stable light field.

[0062] Based on the aforementioned backlight module, this utility model also provides a display device, wherein the display device has all the technical features of the light module, and therefore also has the technical effects brought about by all the aforementioned technical features, which will not be elaborated here.

[0063] Please see Figure 5 The display device further includes a housing plate 5 and multiple wall-mount brackets 6; the housing plate 5 covers the mounting back of the back panel structure 100; the multiple wall-mount brackets 6 are disposed on the housing plate 5 and are spaced apart, and are used to hang on an external wall-mount structure. In this embodiment, by using the multiple wall-mount brackets 6 to mount the display device on an external wall-mount structure, stable support for a large and heavy television can be achieved.

[0064] In this embodiment, the display device has various specific implementations, such as large-size splicing equipment like Mini LED and OLED. In the case of Mini LED, multiple Mini LED light boards are provided on the front mounting side of the back panel, and optical film components are sequentially arranged to form a backlight module on the front mounting side for image display. The reinforcing plate is provided on the back mounting side of the back panel to support the back panel and prevent deformation of the back panel.

[0065] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
