Description

Technical Field

[0001] The utility model relates to the technical field of backlight frame structures, in particular to a fully laminated side-entry backlight frame structure of a liquid crystal display screen tempered glass cover. Background Art

[0002] The existing conventional side-entry backlight structure LCD display module needs to be fully bonded with a tempered glass cover plate. Generally, it is directly bonded with water glue through the finished LCD display module. First, the glue should be sealed between the front frame of the LCD display module and the gap around the LCD panel to prevent the water glue from penetrating into the backlight of the LCD display module during full bonding and causing defects. Then the water glue is filled on the LCD panel until it is flush with the front frame of the module, and then the tempered glass cover plate is placed to exclude air to make it fully bonded. If the front frame of the LCD module is not flat enough, the bonding difficulty will be greatly increased. At the same time, more water glue should be used to fill the height difference between the front frame of the LCD module and the upper and lower parts of the LCD panel, increasing the material cost of full bonding.

[0003] Therefore, in order to solve this problem, a liquid crystal display screen tempered glass cover plate fully laminated side-entry backlight frame structure is needed for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a liquid crystal display screen tempered glass cover plate fully laminated side-entry backlight frame structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liquid crystal display screen tempered glass cover fully laminated side-entry backlight frame structure, including a frame structure, the frame structure including a horizontal plate and a first vertical plate, the first vertical plate is fixedly arranged on one side of the surface of the horizontal plate, a backlight bottom frame structure is arranged on one side of the frame structure, a second vertical plate is arranged on the side of the surface of the backlight bottom frame structure close to the first vertical plate, a liquid crystal panel is arranged on one side of the horizontal plate, and a tempered glass cover is arranged on the upper end of the liquid crystal panel.

[0006] Preferably, a structural adhesive is provided between the horizontal plate and the tempered glass cover plate, and the structural adhesive can play a role in fixing the tempered glass cover plate and the horizontal plate.

[0007] Preferably, a groove is provided on the outer surface of the upper end of the horizontal plate, and the groove designed on the horizontal plate can effectively increase the adhesion of the structural adhesive and improve the gluing efficiency.

[0008] Preferably, a locking screw is provided between the first vertical plate and the second vertical plate, and the first vertical plate and the second vertical plate can be fixed together by the locking screw, so that the frame structure and the backlight bottom frame structure can be quickly fixed together.

[0009] Preferably, a backlight middle frame structure is arranged between the backlight bottom frame structure and the liquid crystal panel. The backlight middle frame structure can fill the height difference between the first vertical plate and the backlight bottom frame structure. The upper end of the backlight middle frame structure is relative to the height of the first vertical plate, so that the tempered glass cover plate of the liquid crystal panel can form a plane after installation, which can make the tempered glass cover plate evenly stressed and ensure the strength of the structural adhesive after curing.

[0010] Preferably, the horizontal plate and the first vertical plate are perpendicular to each other in a "7" shape and fixed to each other. The frame structure is formed by heating an aluminum ingot to a certain temperature and extruding it through a pre-designed mold using relevant equipment. The appearance is an integral, all-aluminum structure to ensure the strength of the frame structure.

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

[0012] 1. Compared with the existing method of directly bonding the finished liquid crystal display module with water glue, the utility model seals the gaps around the liquid crystal display module, the front frame of the module is not flat enough, which increases the difficulty of bonding, and the use of more water glue increases the cost of full bonding. Instead, the utility model changes it to directly bonding the liquid crystal panel to the tempered glass cover plate, and then fixes the tempered glass cover plate with the fully bonded liquid crystal panel to the side-entry backlight frame structure through structural glue.

[0013] 2. The utility model eliminates the step of sealing the gaps around the front frame of the liquid crystal module through the structure, avoids the risk of water glue penetrating into the module backlight and causing defects, and also reduces the difficulty of poor full bonding due to the uneven front frame of the module.

[0014] 3. The utility model only needs a small amount of water glue to directly fully bond the liquid crystal panel, and there is no need to use a large amount of water glue to fill the gap between the front frame of the liquid crystal module and the upper and lower parts of the liquid crystal panel, or use more efficient sheet glue, which not only reduces material costs but also improves production efficiency.
