Description

Technical Field

[0001] This utility model relates to the field of flat panel display technology, and in particular to a dustproof and sealing structure for flat panel backlight modules. Background Technology

[0002] The flat panel backlight module is a core component of the LCD display system. Its core function is to provide a uniform and high-brightness surface light source for the non-self-emissive LCD panel, ensuring clear and true-to-life display images.

[0003] However, existing display backlight modules typically have an opening on the front of the adhesive backing structure for the LED strip connection wires to pass through in order to facilitate installation and wiring. However, this design can easily lead to external dust, particles and other impurities entering the module through the opening during the production process, which can cause problems such as decreased optical performance and display defects (such as dark spots and bright spots), seriously affecting product yield and reliability. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a dustproof and sealing structure for a flat panel backlight module.

[0005] The technical solution is as follows: a dustproof and sealed structure for a flat panel backlight module, including a plastic iron, a backlight assembly, a light strip connecting wire, and a sealing assembly. The inner wall of the plastic iron is provided with steps along the circumference. The backlight assembly is provided at the bottom of the plastic iron. The light strip connecting wire is provided on the backlight assembly. An opening is provided on the front side of the plastic iron for the light strip connecting wire to extend. A sealing assembly is provided at the opening to close the opening.

[0006] As a further preferred option, the front side of the plastic sheet is provided with a bent portion for limiting the position of the backlight assembly.

[0007] As a further preferred embodiment, the enclosure assembly includes an enclosure plate, columns, and T-shaped plates. The enclosure plate is installed at the opening on the front side of the plastic sheeting, multiple columns are spaced apart on the top of the enclosure plate, two T-shaped plates are spaced apart on the rear side of the enclosure plate, and an assembly groove is provided in the middle of the top of the enclosure plate.

[0008] As a further preferred option, a cover plate is also included, with a cover plate fixedly installed at the step in the middle of the PVC-coated iron.

[0009] As a further preferred option, a cotton swab is also included, with the cotton swab positioned between the step on the plastic iron and the backlight assembly.

[0010] As a further preferred option, a groove is provided on the front side of the sealing plate.

[0011] This utility model has the following advantages: Through the multi-layer sealing design of the bending part limit, cotton strip protection, cover plate and sealing plate, this utility model effectively prevents dust from entering the backlight assembly through the opening, avoids optical performance degradation and display defects caused by impurities, and significantly improves product yield and reliability. At the same time, the sealing plate adopts a friction fixing structure of T-shaped plate, column and glue iron, which takes into account both sealing stability and ease of disassembly and assembly.

[0017] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0018] Example: Dustproof and sealing structure for flat panel backlight module, such as Figures 1-4 As shown, the device includes a plastic plate 1, a backlight assembly 2, a light strip connecting wire 3, and a sealing assembly. The inner wall of the plastic plate 1 has a step 101 arranged circumferentially. The backlight assembly 2 is arranged at the bottom of the plastic plate 1. The light strip connecting wire 3 is arranged on the backlight assembly 2. The backlight assembly 2 includes a reflective film, a light guide plate, a light strip, a diffuser film, and a BEF arranged from bottom to top. The light strip connecting wire 3 is connected to the light strip and is used to supply power to the light strip. The front side of the plastic plate 1 has an opening 5 for the light strip connecting wire 3 to extend. The opening 5 is provided with a sealing assembly to close the opening 5. The front side of the plastic plate 1 has a bending part 4 for limiting the position of the backlight assembly 2.

[0019] like Figure 3 As shown, the sealing assembly includes a sealing plate 6, columns 7, and T-shaped plates 8. The sealing plate 6 is installed at the opening 5 on the front side of the glue iron 1. Multiple columns 7 are spaced apart on the top of the sealing plate 6, and two T-shaped plates 8 are spaced apart on the rear side of the sealing plate 6. The sealing plate 6 can close the opening 5. The glue iron 1 has T-shaped grooves and slots corresponding to the opening 5, columns 7, and T-shaped plates 8. The columns 7 and T-shaped plates 8 are all interference-fitted with the glue iron, providing sufficient friction.

[0020] The top center of the sealing plate 6 has an assembly groove 9, and the front side of the sealing plate 6 has a groove 12.

[0021] like Figure 1 As shown, it also includes a cover plate 11, which is fixedly installed at the step 101 in the middle of the glued iron 1.

[0022] like Figure 4 As shown, it also includes a cotton strip 10, which is disposed between the step 101 on the glue iron 1 and the backlight assembly 2.

[0023] During the assembly phase, the workers first install each layer of the backlight assembly 2 inside the bottom of the glue plate 1, and then pass the light strip connecting wire 3 through the opening 5 on the front side of the glue plate 1. Next, the bending portion 4 is bent to limit the position of the backlight assembly 2. At this time, the cotton strip 10 can protect the sides of the backlight assembly 2 to prevent dust from entering the interior of the backlight assembly 2. Then, the cover plate 11 is used to seal the gap between the backlight assembly 2 and the step 101 on the glue plate 1. Afterwards, a sealing plate 6 is taken, and the T-shaped plate 8 on the sealing plate 6 is aligned with the corresponding U-shaped groove on the glue plate 1, while ensuring that the light strip connecting wire 3 is inserted into the assembly groove 9 at the top of the sealing plate 6. Then, the sealing plate 6 is pushed upwards and installed at the opening 5, at which point the column 7 is inserted into the corresponding slot on the glue plate 1. The friction between the T-shaped plate 8, the column 7, and the adhesive iron 1 prevents the sealing plate 6 from falling off, thus sealing the opening 5. This prevents external dust from entering the backlight assembly 2 through the opening 5, ensuring product quality. When the sealing plate 6 needs to be disassembled, it can be removed simply by inserting a screwdriver into the groove 12.
