Especially in consumer electronic products such as TVs, monitors, and laptops, the application of Mini LED technology is becoming more and more extensive.
[0003] However, due to the fact that the backplane shape of the traditional Mini LED display structure cannot be made into a bowl shape to assemble the lamp board and support the optical components, two injection molded middle frames (i.e., the outer middle frame and the inner middle frame) need to be applied to assemble the module. As Figure 1 shown, the inner middle frame of the display module is usually white and is responsible for supporting the optical components; the outer middle frame is arranged outside the inner middle frame to support the glass panel and undertake the appearance shape. With the continuous increase in the market demand for the size of display devices, larger and larger display devices have become the mainstream. However, the high cost of two sets of middle frame molds has led to a relatively high production cost of the entire product. Secondly, the narrow bezel design of the product is more and more in line with customer needs. When using two sets of middle frames, due to the need for sufficient wall thickness for the injection molded parts to be demolded, the product design cannot fully meet the narrow bezel design.

[0043] Figure 1 For the Mini LED display module in the prior art, such as Figure 1As shown in the figure, the Mini LED display module in the prior art includes an inner middle frame 10 and an outer middle frame 7. The inner middle frame 10 is mainly used for installing optical components, and the optical components include a Mini LED component 2, a reflective sheet 3, a diffusion plate 5, a film sheet 6, etc. The outer middle frame 7 is arranged outside the inner middle frame 10 to support the glass panel 9 and undertake the appearance styling.
[0044] Figure 2 The structural schematic diagram of the Mini LED display module provided by the embodiment of the present invention is as Figure 2 shown. The main difference between the Mini LED display module provided by the embodiment of the present invention and the Figure 1 Mini LED display module in is that the inner middle frame 10 of the module is cancelled, and a middle frame assembly structure with support blocks 4 is adopted. Specifically, as Figure 2-15 shown, the Mini LED display module of this embodiment includes a backplane 1, a Mini LED component 2, a reflective sheet 3, support blocks 4, a diffusion plate 5, a film sheet 6, an outer middle frame 7, a buffer cotton 8 and a panel 9. The Mini LED component 2 includes an LED chip and a PCB board. The LED chip is a light source component, and the PCB board can provide power for the LED chip; a plurality of LED chips are evenly and fixedly installed on the PCB board at equal intervals to form the Mini LED component 2. The Mini LED component 2 can be fixedly installed in the backplane 1 by screws. A plurality of bosses 11 are arranged on the inner bottom surface of the backplane 1, and the bottom surface of the Mini LED component 2 abuts against the boss surface, and the bosses 11 carry the Mini LED component 2.
[0045] Furthermore, the reflective sheet 3 is arranged on the surface of the Mini LED component 2. In this embodiment, the reflective sheet 3 is provided with a plurality of avoidance grooves 12 adapted to the shape of the LED chip. The avoidance grooves 12 allow the LED chips to pass through the reflective sheet 3, so that the light of the LED chips is not blocked, and more light can be reflected by the reflective sheet 3, improving the light source efficiency of the module.
[0046] Furthermore, in this embodiment, the support block 4 is a block-shaped body, and a first clamping protrusion 13 is arranged on the bottom side of the support block 4. The first clamping protrusion 13 is used for snap-connecting with the backplane 1. Specifically, a first clamping opening 14 is arranged on the inner side of the edge of the backplane 1, and the first clamping protrusion 13 is clamped in the first clamping opening 14 to enable the support block 4 to be snap-connected with the inner side of the backplane 1. A plurality of first clamping openings 14 can be adapted to the installation of a plurality of support blocks 4. During application, different numbers of support blocks 4 can be adapted according to the different sizes of the product. The snap-connected support blocks 4 in this embodiment have a simple structure, easy installation operation, stable and reliable performance, and can greatly reduce the production cost; and the support blocks 4 are assembled in the backplane 1, and support blocks 4 with different sizes can be designed according to the size requirements of the product to meet the design requirements of ultra-narrow borders.
[0047] Furthermore, in this embodiment, in order to improve the accuracy and stability of the installation of the support block 4, positioning posts 15 are provided on the side surface of the support block 4, and positioning holes 16 are also provided on the inner side of the edge of the back plate 1. The positioning posts 15 are installed in cooperation with the positioning holes 16. Specifically, when assembling the support block 4, the positioning posts 15 are snapped into the positioning holes 16, and the first convex 13 is snapped into the first bayonet 14, ensuring accurate and stable installation.
[0048] Furthermore, in this embodiment, in order to improve the production efficiency and product yield of the support block 4, the support block 4 is integrally formed by an injection molding process, and its material can be PC or silicone. The support block 4 can adopt a multi-cavity production mold, and multiple support blocks 4 of different sizes can be produced at one time, greatly reducing the mold development cost. Compared with the module of two middle frames, the mold opening cost is much reduced, and the economic benefit is better.
[0049] In some embodiments, in order to reinforce the connection between the support block 4 and the back plate 1, double-sided tape (not shown) can be used to bond between the back plate 1 and the support block 4 to enhance the stability of the support block 4.
[0050] Furthermore, in this embodiment, a first support plane 17 is formed on the upper surface of the support block 4, and the first support plane 17 supports the diffusion plate 5.

Preferably, a plurality of support pins 18 can be provided on the inner bottom surface of the back plate 1, and the Mini LED module 2 is provided with a plurality of avoidance holes 19 corresponding to the support pins 18. The support pins 18 pass through the avoidance holes 19 to support the diffusion plate 5, improving the support strength of the diffusion plate 5. Preferably, in order to prevent the diaphragm 6 from falling off during transportation, hanging ears 20 are provided on the upper end surface of the support block 4, and a plurality of limit grooves 21 are provided on the edge of the diaphragm 6. The limit grooves 21 are snapped into the hanging ears 20, and the hanging ears 20 hold the diaphragm 6, thereby tensioning the diaphragm 6 to keep the diaphragm 6 stable and solving the reliability problem of the diaphragm 6 during transportation.
[0051] Furthermore, in this embodiment, the outer middle frame 7 is a frame structure, and a second convex 22 is provided on the edge side of the outer middle frame 7. The second convex 22 is used for snap connection with the back plate 1 to ensure the structural stability of the outer middle frame 7 and prevent reliability problems caused by outward turning, etc. Specifically, a second bayonet 23 is provided on the outer side of the edge of the back plate 1, and the second convex 22 is snap-connected to the second bayonet 23 so that the outer middle frame 7 is snap-connected to the outer side of the back plate 1. After being snap-connected to the back plate 1, the outer middle frame 7 can press the edge of the diaphragm 6 and further press the diffusion plate 5 to keep the diffusion plate 5 and the diaphragm 6 stable.
[0052] Furthermore, in this embodiment, the panel 9 is preferably a liquid crystal panel, and the buffer cotton 8 is preferably double-sided foam. The liquid crystal panel is firmly installed by bonding with the outer middle frame 7 through the double-sided foam.
[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
