Description

Technical Field

[0001] This utility model relates to the field of liquid crystal module technology, specifically to an L-shaped snap-fit ​​sealing strip for dust prevention of the diffusion film of a liquid crystal module. Background Technology

[0002] Simply put, an LCD module is a screen plus a backlight assembly. The display component of an LCD TV is the LCD module, which is equivalent to the picture tube in a CRT. Other parts include power supply circuits, signal processing circuits, and of course, the casing. The module is mainly divided into the screen and the backlight assembly.

[0003] The above-mentioned technical conditions also have defects: the existing diffusion film is only sealed with a strip-shaped sealing strip between itself and the module frame, which has poor dust prevention effect during long-term use, causing dust to easily penetrate into the module and thus affecting the display effect of the LCD module.

[0004] Based on this, this utility model designs an L-shaped snap-fit ​​sealing strip for dust prevention of the diffusion film of a liquid crystal module, in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an L-shaped snap-fit ​​sealing strip for dust prevention of the diffusion film of a liquid crystal module, so as to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an L-shaped snap-fit ​​sealing strip for dust prevention of a liquid crystal module diffusion film, comprising a strip body and a diffusion film, wherein the strip body is attached to the edge portion of the diffusion film, the strip body includes a long side and a short side, the short side is vertically disposed on the top side of the long side, and a plurality of main sealing blocks are disposed at the bottom of the short side, the bottom edge portion of the main sealing blocks abutting against the upper edge of the diffusion film, and a plurality of auxiliary sealing blocks are also disposed on the side of the long side, one side of the auxiliary sealing blocks abutting against the edge side of the diffusion film.

[0007] By adopting the above technical solution, multi-directional sealing is achieved. The main sealing block is directly pressed against the upper surface of the diffusion membrane to prevent dust from entering from above, while the auxiliary sealing block is pressed against the side of the diffusion membrane to block lateral intrusion. This dual sealing mechanism automatically snaps in during installation without the need for additional fasteners.

[0008] Preferably, a plurality of corner sealing blocks are provided on the inner side of the connection between the short side and the long side, and one side of the corner sealing block is in contact with the upper edge of the diffusion film.

[0009] By adopting the above technical solution, the corner sealing block is located on the inside of the L-shaped corner and directly contacts the upper edge of the diffusion membrane. This design fills the weak point of the traditional seal at the connection, prevents dust from seeping in from the corner gap, and enhances the overall structural stability.

[0010] Preferably, the multiple corner sealing blocks are staggered between the multiple main sealing blocks and the multiple auxiliary sealing blocks.

[0011] By adopting the above technical solution, the corner sealing blocks are arranged alternately between the main sealing block and the auxiliary sealing block to form a labyrinthine sealing path. This layout reduces the straight infiltration channels of dust, increases the number of barrier layers, and optimizes the stress distribution of the sealing blocks to avoid sealing failure caused by local deformation.

[0012] Preferably, both the main sealing block and the auxiliary sealing block are lip-shaped sealing structures.

[0013] By adopting the above technical solution, the lip seal structure can achieve high sealing performance under low pressure, adapt to the slight undulations of the diffusion film, and has self-compensating wear capability, thus extending its service life.

[0014] Preferably, the bottom edge of the main sealing block is provided with a first micro groove, and the side of the auxiliary sealing block is provided with a second micro groove.

[0015] By adopting the above technical solution, the first micro-groove and the second micro-groove form a capillary structure on the contact surface of the sealing block; the groove captures and retains tiny dust particles, preventing them from further intruding into the diffusion film area, while enhancing the sealing contact through surface tension.

[0016] Preferably, the micro-grooves are V-shaped or U-shaped.

[0017] By adopting the above technical solution, the V-shaped or U-shaped groove shape facilitates the accumulation and removal of dust.

[0018] In summary, this application has the following beneficial technical effects: it significantly improves the dustproof performance of the diffusion film edge, and blocks dust intrusion through multi-directional sealing and micro-groove design, ensuring display brightness and uniformity; the L-shaped snap-fit ​​structure simplifies the installation process and reduces production costs; the lip seal and staggered layout enhance sealing reliability and environmental adaptability; the overall solution has a compact structure, is easy to integrate into existing LCD modules, and is suitable for high-requirement application scenarios such as TVs and monitors.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] An L-shaped snap-fit ​​sealing strip for dust prevention of a liquid crystal module diffusion film includes a strip body 1 and a diffusion film 2. The strip body 1 is attached to the edge of the diffusion film 2, which can seal the edge of the diffusion film 2 without affecting the installation of the liquid crystal panel on the diffusion film 2. The strip body 1 includes a long side 11 and a short side 12. The short side 12 is vertically arranged on the top side of the long side 11, forming an L-shaped snap-fit ​​structure. Multiple main sealing blocks 13 are arranged at the bottom of the short side 12, and the bottom edge of the main sealing blocks 13 abuts against the upper edge of the diffusion film 2. Multiple auxiliary sealing blocks 14 are also arranged on the side of the long side 11, and one side of the auxiliary sealing blocks 14 abuts against the side edge of the diffusion film 2. Through multi-directional sealing, the sealing degree of the diffusion film after installation can be improved, and the impact of dust on the diffusion film 2 can be reduced.

[0025] Furthermore, multiple corner sealing blocks 15 are provided on the inner side of the connection between the short side 12 and the long side 11. One side of the corner sealing block 15 contacts the upper edge of the diffusion membrane 2, which can further improve the sealing effect.

[0026] Furthermore, multiple corner sealing blocks 15 are staggered between multiple main sealing blocks 13 and multiple auxiliary sealing blocks 14, such as... Figure 3As shown, this reduces the path for dust to seep in.

[0027] Furthermore, both the main sealing block 13 and the auxiliary sealing block 14 are lip-shaped sealing structures, which can improve their sealing effect.

[0028] Furthermore, a first micro-groove 16 is provided at the bottom edge of the main sealing block 13, and a second micro-groove 17 is provided on the side of the auxiliary sealing block 14, which further blocks dust through capillary structure.

[0029] Furthermore, the micro-grooves are V-shaped or U-shaped.

[0030] The implementation principle of this embodiment is as follows: When the edge strip body 1 is snapped onto the edge of the diffusion film 2, the sealing blocks of the long side 11 and the short side 12 abut against the film surface and side under the action of the installation force, and the lip structure elastically deforms to fit the uneven area of ​​the diffusion film 2; the main sealing block 13 and the corner sealing block 15 cover the upper edge, and the auxiliary sealing block 14 presses the side to form a continuous sealing strip; at the same time, the micro groove captures dust particles through capillary effect to prevent them from entering the display area; the entire snapping process does not require glue or screw fixation, and relies on the self-locking structure to achieve reliable sealing and adapt to the material expansion caused by temperature changes.
