Technical Field
[0001] This utility model relates to the field of display technology, and in particular to an ultra-thin liquid crystal display module that prevents light leakage. 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. The two parts are assembled together, but they work independently (i.e., the circuits are not related).
[0003] The existing technology has the following drawbacks: during the assembly process, some existing display modules experience slight misalignment between the backlight assembly and the LCD panel, resulting in gaps between the display module and the casing, causing light leakage. Light leakage leads to uneven brightness in local areas, inaccurate color reproduction in dark scenes, and affects image contrast and color fidelity, thereby reducing the comfort of using the display module. To address these issues, an anti-light leakage ultra-thin LCD display module is proposed. Utility Model Content

[0035] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figures 1-3This utility model provides an embodiment of an ultra-thin LCD display module with light leakage prevention, comprising a back frame 1, a light guide plate 2 disposed inside the back frame 1, a light source module 3 disposed on the side wall of the light guide plate 2, and a placement cavity provided inside the back frame 1 to facilitate the connection between the light guide plate 2, the light source module 3 and the back frame 1. An adjustment frame 5 is slidably connected inside the back frame 1, and a placement frame 4 is fixedly connected to the side wall of the adjustment frame 5. The movement of the adjustment frame 5 causes the placement frame 4 to slide inside the back frame 1. A limiting sliding hole is provided inside the back frame 1, through which the adjustment frame 5 passes and is slidably connected. The limiting sliding hole ensures stable sliding of the adjustment frame 5 inside the back frame 1, thereby adjusting the placement frame 4 to different positions.
[0037] Furthermore, the placement frame 4 is slidably connected inside the back frame 1. A sealing rubber gasket 7 is snapped into the inside of the placement frame 4. The side wall of the sealing rubber gasket 7 contacts the side wall of the light guide plate 2 and the light source module 3. By using the sealing rubber gasket 7 to fit against the side wall of the light guide plate 2 and the light source module 3, light leakage is avoided during use. A connecting groove is provided on the side wall of the placement frame 4. The connecting groove is L-shaped. The sealing rubber gasket 7 is inserted into the inside of the placement frame 4. An adjustment mechanism 6 is provided inside the adjustment frame 5. A disassembly component 8 is provided on the inner bottom of the placement frame 4.
[0038] Reference Figures 2-4 The adjustment mechanism 6 includes a push plate 61, which is slidably connected inside the adjustment frame 5. The top of the adjustment frame 5 has a sliding hole, and the top of the push plate 61 has a push rod that matches the size of the positioning hole. The push plate 61 is slidably driven to slide inside the adjustment frame 5 by sliding the push rod. There are two push plates 61, and the two push plates 61 are elastically connected to the opposite surfaces by a positioning spring 63. Pushing the push plate 61 compresses the positioning spring 63, causing the positioning spring 63 to deform. When resetting, the rebound of the positioning spring 63 causes the push plate 61 to slide and reset. An adjustment block 62 is fixedly connected to the side wall of the push plate 61. The inner side wall of the limiting sliding hole has multiple adjustment holes of equal size and equidistant distribution. During the process of pushing the push plate 61, the adjustment block 62 is driven to slide inside the adjustment frame 5. The adjustment block 62 passes through the adjustment frame 5 and is inserted into the adjustment hole. The setting of the adjustment hole allows the adjustment block 62 to slide to different positions and stably insert to meet the adjustment effect of the adjustment frame 5 at different positions.
[0039] Reference Figures 3-5The disassembly assembly 8 includes a disassembly plate 82, which is slidably connected inside the placement frame 4. The bottom of the sealing rubber pad 7 is in contact with the top of the disassembly plate 82. The disassembly plate 82 is designed to allow the sealing rubber pad 7 to spring back after disassembly. The bottom of the disassembly plate 82 is elastically connected to the placement frame 4 via a return spring 81. Pushing the disassembly plate 82 compresses the return spring 81, causing it to deform. During reset, the spring 81's rebound causes the disassembly plate 82 to slide and reset. A disassembly block 83 is fixedly connected to the side wall of the sealing rubber pad 7. The disassembly block 83 passes through and is slidably connected in the connecting groove. The connecting groove and the disassembly block 83 ensure a stable connection between the sealing rubber pad 7 and the placement frame 4.
[0040] Working principle: In use, the light guide plate 2 and the light source module 3 are pasted inside the back frame 1. Then, the sealing rubber gasket 7 is used to fit the side walls of the light guide plate 2 and the light source module 3 to ensure the sealing of the light guide plate 2 and the light source module 3 during installation and to prevent light leakage. When the dimensions of the light guide plate 2 and the light source module 3 are different and need to be adjusted for sealing, the push plate 61 is pushed and the positioning spring 63 is squeezed, which drives the adjustment block 62 into the interior of the adjustment frame 5. Then, the adjustment frame 5 is slid inside the back frame 1. The sliding of the adjustment frame 5 drives the placement frame 4 and the sealing rubber gasket 7 to slide to the appropriate position. Then, the sliding of the push plate 61 is released. At the same time, the rebound of the positioning spring 63 drives the push plate 61 to slide and drive the adjustment block 62 to reset and insert it into the interior of the back frame 1. The sealing rubber gasket 7 is used to seal the light guide plate 2 and the light source module 3.
[0041] When the sealing rubber gasket 7 is damaged after long-term use and needs to be replaced, the sealing rubber gasket 7 is pushed to drive the disassembly block 83 to slide inside the placement frame 4. Then, the reset spring 81 drives the disassembly plate 82 to rebound and reset, thereby removing the sealing rubber gasket 7 from the inside of the placement frame 4, thus achieving the effect of disassembling and replacing the sealing rubber gasket 7.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
