Technical Field

[0001] The utility model relates to the field of television back panels, in particular to a back panel for a liquid crystal television backlight module. Background Art

[0002] The backplane in the LCD TV backlight module is a key component of the overall structure. It not only ensures the stability and flatness of the backlight module, but also undertakes the important task of connecting and fixing other components. The backplane material must have both strength and lightness, and aluminum plates or tempered glass are often used. In the design of ultra-thin LCD TVs, the integration of the backplane and the rear shell of the entire machine can further reduce the thickness and improve the aesthetics. The design and material selection of the backplane are crucial to the backlight effect and affect the display effect and service life of the TV. Therefore, the backplane is an indispensable part to ensure the stability of the LCD TV backlight module and optimize the display effect.

[0003] During the installation of the LCD TV backlight module, the light strip on the back panel is usually installed by the traditional glue sticking method. However, this method has certain disadvantages in actual operation. Specifically, the installer needs to apply glue on the surface of the back panel and then stick the light strip on it. However, in this process, the application position and amount of glue are often difficult to control accurately, which can easily lead to glue overflow or insufficient application, thereby affecting the adhesion firmness of the light strip. This inaccurate operation not only affects the installation quality of the back panel and the light strip, but also reduces the convenience of installation. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a back panel for a liquid crystal TV backlight module, so as to solve the technical problem that the application position and amount of glue are not accurate, resulting in glue overflow and loose adhesion when the light strip is attached, thereby reducing the convenience of installing the back panel and the light strip.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a back panel for a liquid crystal TV backlight module, comprising a back panel body and a light strip, a surface of the light strip is provided with a plurality of through holes, a surface of the back panel body is provided with a limiting mechanism, the limiting mechanism comprises a limiting column, and limiting grooves are provided on both sides of the limiting column.

[0006] By adopting the above technical solution, the glue is limited by the limiting groove, and the application position of the glue can be accurately determined, which provides clear guidance for operators when applying the glue, avoiding inaccurate positioning caused by random application, thereby ensuring that the light strip can be accurately pasted at the predetermined position.

[0007] Furthermore, the limiting groove is used to store glue, and the limiting groove has a rectangular structure.

[0008] By adopting the above technical solution, the limiting groove is used to store glue, ensuring that the glue can be stored in a specific position in an orderly and stable manner, so that when installing the light strip, the glue can be accurately and appropriately applied to the contact surface between the back panel body and the light strip, thereby improving the accuracy and efficiency of pasting.

[0009] Furthermore, the light strip is clamped with the back panel body through the through hole and the limiting column.

[0010] By adopting the above technical solution, this connection method provides a simple and quick way to fix the light strip. Compared with the traditional glue sticking method, the clip-on method is more convenient and greatly improves the installation efficiency.

[0011] Furthermore, a plurality of the limiting mechanisms are provided, and the plurality of limiting mechanisms are arranged in an equidistant array.

[0012] By adopting the above technical solution, these limiting mechanisms are arranged in an equidistant array, so that the light strip can be evenly and stably supported during installation.

Through the clamping action of the card, it can ensure that the line is stably fixed in the predetermined position, thereby improving the stability and safety of the overall system.

[0017] Furthermore, a plurality of lamp beads are arranged on the light strip, and the end of the light strip is engaged with the back panel body through a clip.

[0018] By adopting the above technical solution, multiple lamp beads can provide sufficient lighting intensity and uniform backlight effect. The distribution of multiple lamp beads can ensure that the backlight module can provide comprehensive and uniform light, thereby improving the display effect.

[0019] Furthermore, the limiting posts, limiting grooves, wire holes, cards and clips are all manufactured by integrally stamping the back plate.

[0020] By adopting the above technical solution, the one-piece stamping manufacturing greatly improves the production efficiency.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0036] The following describes an embodiment of the utility model based on its overall structure.

[0037] Embodiment 1:

[0038] A back plate for a liquid crystal television backlight module, such as Figure 1-Figure 6 As shown, it includes a back panel body 1 and a light strip 3. A plurality of through holes 8 are provided on the surface of the light strip 3. A limiting mechanism 5 is arranged on the surface of the back panel body 1. The limiting mechanism 5 includes a limiting column 501. Limiting grooves 502 are arranged on both sides of the limiting column 501. The limiting grooves 502 are used to limit the glue, so that the application position of the glue can be accurately determined. This provides clear guidance for operators when applying the glue, avoiding inaccurate positioning caused by random application, thereby ensuring that the light strip 3 can be accurately pasted at the predetermined position. At the same time, the limiting grooves 502 can also effectively prevent the glue from overflowing to the outside of the installation surface of the light strip 3. The glue is limited in the groove and will not flow out of the installation surface, thereby maintaining the overall beauty and cleanliness, not only improving the convenience of gluing between the light strip 3 and the back panel body 1, but also enhancing practicality, making the installation process more efficient and accurate.

[0039] See also Figure 2 , Figure 5 The limiting groove 502 is used to store glue. The limiting groove 502 has a rectangular structure. The limiting groove 502 is used to store glue, which ensures that the glue can be stored in a specific position in an orderly and stable manner, so that when installing the light strip 3, the glue can be accurately and appropriately applied to the contact surface between the back panel body 1 and the light strip 3, thereby improving the accuracy and efficiency of pasting. At the same time, the limiting groove 502 has a rectangular structure, which not only makes the glue in the groove more evenly distributed, but also facilitates the operator to judge and control when applying the glue.
