Description

Technical Field

[0001] The utility model relates to the technical field of backlight source modules, in particular to a low-defect light leakage-proof backlight source module. Background Art

[0002] The backlight module is an LED light source device used for liquid crystal display screens. It is mainly composed of components such as LED lamp beads, light guide plates, reflectors, optical films and supporting structures. Its function is to provide backlighting through LEDs, and to make the light evenly illuminate the entire surface of the liquid crystal display screen through the light guide plate and other optical structures. In liquid crystal displays, this backlight module is usually placed behind the liquid crystal panel to provide the light required for display, thereby producing clear and bright images.

[0003] However, during use, the installation sealing of the backlight module is often poor, resulting in some light leakage, affecting the use of the backlight module. For this reason, we propose a low-defect anti-light leakage backlight module to solve the existing problem. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and propose a low-defect light leakage-proof backlight source module.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-defect anti-light leakage backlight module, including a fixing structure and a backlight module, the fixing structure includes a bottom shell, a top frame is arranged on the upper end of the bottom shell, the top frame and the outer side of the bottom shell are sleeved with relatively distributed clamping sleeves 1 and 2, the backlight module includes a mounting shell located inside the bottom shell, an LED light source is suspended at the center of the mounting shell, a light guide plate is arranged below the LED light source, a reflective sheet is arranged above the light guide plate, an optical film is arranged on the upper end of the reflective sheet, and a liquid crystal panel is arranged on the upper end of the optical film.

[0006] Preferably, a docking groove is provided inside the upper end of the bottom shell, and the lower end of the top frame is located inside the docking groove. When the top frame is docked with the bottom shell through the docking groove, it is positioned for easy installation.

[0007] Preferably, mounting holes are provided inside the opposite ends of the bottom shell and the top frame, and the mounting holes are used for inserting the fixing parts to fix the bottom shell and the top frame.

[0008] Preferably, the bottom shell and the top frame are both provided with side rings, and the side rings are clamped and installed with the ferrule 1 and the ferrule 2. When the ferrule 1 and the ferrule 2 are clamped on the top frame and the bottom shell, the positioning before installation is achieved by being sleeved on the outside of the side ring.

[0009] Preferably, the inner walls of the ferrule 1 and ferrule 2 are both provided with sealing pads. When the side ring squeezes the density pad, the gap between the side ring and the ferrule 1 and ferrule 2 is filled with the sealing pad, thereby improving the sealing effect.

[0010] Preferably, the opposite ends of the ferrule 1 and ferrule 2 are both provided with mounting blocks, the mounting blocks are provided with mounting holes, and the mounting holes inside the mounting blocks have the same specifications as the mounting holes inside the bottom shell and the top frame. The mounting blocks are used for docking the ferrule 1 and ferrule 2, and the mounting holes of the same specifications facilitate the assembly of the fixing parts.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model adds a first clamp and a second clamp on the side of the fixed structure of the backlight module. The first clamp and the second clamp are installed at the fixed structure joint of the backlight module for sleeve sealing, which avoids the problem of light source penetrating to the outside due to loose sealing at the fixed structure joint. The first clamp and the second clamp are used to improve the sealing of the fixed structure joint of the backlight module, thereby improving the yield rate during use.
