Description

Technical Field

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

[0002] Most of the existing conventional direct-down backlight structure LCD display modules cannot be directly fully bonded to the tempered glass cover. Because the direct-down backlight structure is bottom-emitting, the optical film and the diffuser are suspended structures supported by a certain number of support columns. When the water glue is filled on the LCD panel until it is flush with the front frame of the module, when the tempered glass cover is placed under pressure to expel the air, the position without the support column will collapse downward, causing damage to the backlight and the LCD panel. At the same time, the height difference between the front frame of the LCD module and the upper and lower parts of the LCD panel also needs to be filled with more water glue, 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 direct-down 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 full-laminated direct-down 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 direct-down 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, a tempered glass cover is arranged on the upper end of the liquid crystal panel, and an extension block is fixedly arranged on one side of the surface of the backlight bottom frame structure.

[0006] Preferably, a limiting protrusion is fixedly provided on one side of the upper end of the extension block. When the frame structure and the backlight bottom frame structure are installed, the lower end of the first vertical plate in the frame structure contacts the extension block to improve the subsequent supporting effect of the frame structure. The limiting protrusion can limit the lower end of the first vertical plate, so that the first vertical plate remains vertical and the horizontal plate remains horizontal.

[0007] Preferably, a groove is provided on the outer surface of the upper end of the horizontal plate. The groove designed on the horizontal plate can effectively increase the adhesion of the structural adhesive and improve the gluing efficiency. At the same time, in the present application document, since the first vertical plate has support requirements, its length is equivalent to that of the horizontal plate. In order to facilitate distinction during later processing, the groove can also be used to distinguish the first vertical plate and the horizontal plate.

[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. At this time, the lower end of the first vertical plate is in contact with the extension plate to ensure the supporting stability of the frame structure and the backlight bottom frame structure.

[0009] 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.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. Compared with the existing method of directly bonding the finished liquid crystal display module with water glue, when the tempered glass cover is placed and the air is expelled under pressure, the position without the support column will collapse downward, causing damage to the backlight and the liquid crystal panel. Using more water glue increases the cost of full bonding. Instead, the method is changed to directly bonding the liquid crystal panel to the tempered glass cover, and then fixing the tempered glass cover with the fully bonded liquid crystal panel to the direct-down backlight frame structure by structural glue.

[0012] 2. After the installation of the utility model is completed, the backlight frame structure and the frame structure can form a plane, and then the tempered glass cover plate can be installed, making the installation of the tempered glass cover plate more stable. Subsequently, after the liquid crystal panel is fully bonded, the stress point is on the tempered glass cover plate, and the stress point of the tempered glass cover plate is on the direct-down backlight frame structure and the frame structure, which will not cause the problem of optical film material and diffuser plate collapsing downward.

[0013] 3. The utility model directly fully bonds the liquid crystal panel only with a small amount of water glue, which can be filled between the tempered glass cover plate and the horizontal plate. 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.
