Problems solved by technology
[0003] However, the current method of screw-locking flat splicing parts to produce backplanes has the following disadvantages: 1. There are many screw-locks. During the production and installation process, it takes a lot of manual installation, and the mass production is not good. Low; 2. There are many screw holes, which are often prone to missing locks, making the backboard not fast; 3. A lot of screw holes are processed on the backboard, so that the overall pressure resistance and other resistance of the backboard are improved. The reduction is very large, affecting the quality and life of the backplane

Embodiment Construction
[0031] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0032] The present invention proposes a large-size backlight module backplane splicing structure.
[0033] refer to figure 1 , figure 1 It is a structural schematic diagram of the first embodiment of the large-size backlight module backplane splicing structure of the present invention.
[0034] In the first embodiment of the present invention, the backplane splicing structure of the large-size backlight module, wherein the backplane includes a bottom plate 10 and a splicing piece 20 spliced at the end side of the bottom plate 10;
[0035] The splicing piece 20 comprises a side plate 22, an upper supporting plate 23 and a lower supporting plate 21 which are arranged on the same side of the side plate 22 and are perpendicular to the side plate 22; The lower bottom surface of 23 forms the clamping opening 24 for cla...

A backboard splicing structure of a large-size backlight module. A backboard comprises a bottom flat plate (10), and a splicing piece (20) spliced on an end side of the bottom flat plate (10). The splicing piece (20) comprises a side plate (22), and an upper support plate (23) and a lower support plate (21) both disposed on a same side of the side plate (22) and perpendicular to the side plate (22). A lower bottom surface of the upper support plate (23), an upper top surface of the lower support plate (21) and the side plate (22) form a clamping mouth (24) used for clamping the bottom flat plate (10). Column groove assembling structures are disposed on the lower bottom surface of the upper support plate (23) and the bottom flat plate (10). Fastening screws are disposed between the bottom flat plate (10) and the splicing piece (20). By using the backboard splicing structure of the large-size backlight module, that fixing in the two-dimensional direction of the three-dimensional direction is implemented, and fixing in the third-dimensional direction is implemented by using fewer screws, so that the objective of the fastened mounting is achieved, working procedures are reduced, consumed screws are greatly reduced, the time consumed in the assembly is shortened, and the labor efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backplane splicing structure of a large-size backlight module and a liquid crystal display device. Background technique [0002] With the innovation of LCD technology, large-size LCD TVs are becoming more and more mature, and the unit price is getting lower and lower. The technological innovation of large-size backlights has also become a new trend. Most of the existing large-size module backplanes use flat panels. The way of splicing forms a complete backplane. [0003] However, the current method of screw-locking flat splicing parts to produce backplanes has the following disadvantages: 1. There are many screw-locks. During the production and installation process, it takes a lot of manual installation, and the mass production is not good. Low; 2. There are many screw holes, which are often prone to missing locks, making the backboard not fast; 3. A lot of scre...
