Description

Technical Field

[0001] This utility model relates to the field of LED backlight technology, specifically a Mini LED display backlight packaging structure. Background Technology

[0002] Mini LED displays are an improved LED backlighting technology, with backlights composed of LED chips smaller than 200 micrometers. This technology is commonly used to enhance the performance of LCD displays by improving overall screen contrast and brightness through more precise control of screen brightness.

[0003] In Mini LED displays, the connection between the Mini LED boards and the display back panel is usually achieved by adhesive. However, gaps exist between multiple Mini LED boards, which need to be encapsulated with wires. Traditionally, encapsulation is also done by adhesive, which can easily lead to insufficient sealing. In addition, gaps exist between the encapsulation wires and the Mini LED boards, which can easily cause light leakage, which is not conducive to practical applications.

[0004] Therefore, those skilled in the art provide a Mini LED display backlight packaging structure to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a Mini LED display backlight packaging structure, which solves the problem mentioned in the background technology that the packaging in traditional methods is also done by gluing, which easily leads to insufficient sealing and gaps between the packaging lines and the Mini LED board, easily causing light leakage.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a Mini LED display backlight packaging structure, including a display back panel and a Mini LED board, wherein the Mini LED board is mounted on the surface of the display back panel with adhesive, and packaging components are provided on all four sides of the Mini LED board, wherein the packaging components are used to encapsulate the four sides of the Mini LED board.

[0007] The encapsulation assembly includes a groove and an encapsulation strip. The groove is formed around the Mini LED board, and the encapsulation strip is installed inside the groove by adhesive.

[0008] Four fastening components are provided on the outer side of the display back panel, which are used to fasten the sealing strip.

[0009] The above technical solution utilizes encapsulation components, with grooves created around the Mini LED board in conjunction with encapsulation strips. This encapsulates and seals the gaps between adjacent Mini LED boards, preventing light leakage and ensuring high equipment yield. Furthermore, by incorporating fastening components with the encapsulation components, the stability of the encapsulation strip installation is increased, further reinforcing the connection stability between the Mini LED board and the display back panel, which is beneficial for practical applications.

[0010] Preferably, the encapsulation component further includes notches and positioning posts. The notches are formed on the four sides of the Mini LED board, and the positioning posts are installed at the bottom of the encapsulation strip. Each positioning post passes through the corresponding notch.

[0011] By utilizing the above technical solution and the cooperation between the notch and the positioning post, the position of the Mini LED board can be further limited by the positioning post.

[0012] Preferably, the fastening assembly includes a positioning hole, a threaded hole, and a fastening screw. The positioning hole is located on the back panel of the display and directly below the positioning post. The bottom of the positioning post passes through the positioning hole and extends to the bottom of the back panel of the display. The threaded hole is located at the bottom of the positioning post, and the fastening screw is threaded into the inside of the threaded hole.

[0013] The above technical solution utilizes the cooperation between the positioning post and the positioning hole to position the encapsulation strip and the back panel of the display, thereby facilitating subsequent installation operations.

[0014] Preferably, mounting holes are provided at all four corners of the display back panel.

[0015] The above technical solution allows the monitor back panel to be installed in a designated location using the mounting holes.

[0016] Preferably, the Mini LED board has LED beads installed at equal intervals on the side away from the back panel of the display.

[0017] The above technical solution utilizes LED beads to emit light, thereby enabling screen illumination.

[0018] Preferably, the diameter of the end of the fastening screw furthest from the positioning post is greater than the diagonal length of the positioning hole.

[0019] The above technical solution ensures that after the fastening screw is screwed into the threaded hole, its end will abut against the side of the display back panel away from the Mini LED board. This allows the fastening screw to secure and install the positioning post and the encapsulation strip. At the same time, the pressing action of the encapsulation strip allows the Mini LED board to fit more tightly against the display back panel, thereby further strengthening the connection stability between the Mini LED board and the display back panel, which is beneficial for practical applications.

[0020] This utility model provides a Mini LED display backlight packaging structure, which has the following beneficial effects:

[0021] 1. The backlight encapsulation structure of this Mini LED display screen, by setting up encapsulation components, uses grooves to be opened around the Mini LED board in conjunction with encapsulation strips to encapsulate and seal the gap between two adjacent Mini LED boards, thereby preventing light leakage from the gap between the Mini LED boards and ensuring the yield rate of the equipment.

[0022] 2. This Mini LED display backlight encapsulation structure, by setting fastening components to work with the encapsulation components, can increase the stability of the encapsulation strip installation, and at the same time, can further strengthen the connection stability between the Mini LED board and the display back panel, which is beneficial to practical applications.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figure 1 This utility model provides a Mini LED display backlight packaging structure, including a display backplate 1 and a Mini LED board 2. The Mini LED board 2 is mounted on the surface of the display backplate 1 with adhesive, which initially fixes the display backplate 1 and the Mini LED board 2. Mounting holes 10 are provided at each of the four corners of the display backplate 1, allowing the display backplate 1 to be installed in a designated position. LED beads 11 are equidistantly mounted on the side of the Mini LED board 2 away from the display backplate 1, emitting light to achieve screen illumination.

[0031] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In one aspect of this embodiment, encapsulation components are provided around the perimeter of the Mini LED board 2. These encapsulation components encapsulate the perimeter of the Mini LED board 2. The encapsulation components include grooves 3, notches 4, encapsulation strips 5, and positioning posts 6. Grooves 3 are formed around the perimeter of the Mini LED board 2. The encapsulation strips 5 are installed inside the grooves 3 using adhesive. The adhesive initially installs the encapsulation strips 5 inside the grooves 3. The cooperation between the grooves 3 and the encapsulation strips 5 forms a stepped installation method, avoiding vertical installation and effectively preventing light leakage. Notches 4 are formed on the four sides of the Mini LED board 2. Positioning posts 6 are installed at the bottom of the encapsulation strips 5, and each positioning post 6 penetrates the corresponding notch 4. The cooperation between the notches 4 and the positioning posts 6 allows the positioning posts 6 to further limit the position of the Mini LED board 2.

[0032] Reference Figure 3 and Figure 5 In one aspect of this embodiment, four fastening components are provided on the outer side of the display back panel 1. These fastening components are used to fasten the encapsulation strip 5. Each fastening component includes a positioning hole 7, a threaded hole 8, and a fastening screw 9. The positioning hole 7 is located on the display back panel 1 and directly below the positioning post 6. The bottom of the positioning post 6 passes through the positioning hole 7 and extends to the bottom of the display back panel 1. The engagement between the positioning post 6 and the positioning hole 7 allows for positioning of the encapsulation strip 5 relative to the display back panel 1, facilitating subsequent installation. The threaded hole 8 is located at the bottom of the positioning post 6, and the fastening screw 9 is threaded into the threaded hole 8, facilitating installation. The diameter of the end of the fastening screw 9 furthest from the positioning post 6 is greater than the diagonal length of the positioning hole 7, ensuring that after the fastening screw 9 is screwed into the threaded hole 8, it... Figure 3As shown, its end will abut against the side of the display back panel 1 away from the Mini LED board 2, thereby using the fastening screw 9 to fasten and install the positioning post 6 and the encapsulation strip 5. At the same time, the pressing action of the encapsulation strip 5 allows the Mini LED board 2 to fit more tightly onto the display back panel 1, thereby further strengthening the connection stability between the Mini LED board 2 and the display back panel 1, which is beneficial for practical applications.

[0033] Working principle:

[0034] In use, the Mini LED board 2 is first installed on the surface of the display back panel 1 with glue. Then, the encapsulation strip 5 is placed in the groove 3. The groove 3 and the encapsulation strip 5 cooperate to form a stepped installation method, which can avoid the vertical installation method and thus effectively prevent light leakage.

[0035] Simultaneously, the positioning post 6 at the bottom of the sealing strip 5 passes through the notch 4, and its bottom passes through the positioning hole 7. Finally, the fastening screw 9 is tightened into the threaded hole 8 at the bottom of the positioning post 6. Figure 3 As shown, the end of the mini LED board 2 is placed against the side of the back panel 1 away from the mini LED board 2. The positioning post 6 and the encapsulation strip 5 are then fastened and installed using the fastening screw 9. At the same time, the pressing action of the encapsulation strip 5 allows the mini LED board 2 to fit more tightly against the back panel 1 of the display, thereby further strengthening the connection stability between the mini LED board 2 and the back panel 1 of the display. It also makes the connection between the encapsulation strip 5 and the grooves 3 around the mini LED board 2 more compact, which is beneficial for practical applications.
