Problems solved by technology

[0003] According to the needs of different liquid crystal display devices, traditional backplanes are stamped to form convex hulls on the backplane, which are used to fix components such as PCB boards. The way of stamping to form convex hulls is inconvenient to process, and it is also difficult to realize the standardization and generalization of the backplane. design, the cost of the backplane is further increased

Abstract

The invention discloses a locking accessory, a backlight module and a liquid crystal display device. The locking accessory for fixing a printed circuit board (PCB) on a back board is characterized in that a clamping structure is arranged at the top of the locking accessory which is fixed with the PCB; and a fixing structure used for fixing the locking accessory on the back board is arranged at the root of the locking accessory. Since the independent locking accessory structure is adopted, the locking accessory can be used for selectively and fixedly installing the PCB on the back board at positions at which the PCB is required to be fixed, the standardized and universal design of the backboard can be realized and the cost is reduced; and moreover, since the clamping structure is adopted between the locking accessory and the PCB, compared with a screw fixation method, riveting method and the like, the installation efficiency is higher, the production efficiency is improved and the cost is further reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display, more specifically, to a lock accessory, a backlight module and a liquid crystal display device. Background technique [0002] The liquid crystal display device includes a liquid crystal panel and a backlight module, and the bottom of the backlight module has a back plate for sealing the module and fixing the components in the mold. Existing backplanes all use integral backplanes, which are generally integrally formed by metal stamping or plastic injection, which makes the product relatively heavy and has a high material cost. For a large-sized backplane, the cost is higher due to the need to use larger stamping equipment, and the corresponding mold size is large, the structure is complex, and the mold cost is also high. With the increasingly fierce market competition, it is becoming more and more important to effectively reduce design costs, so saving material costs and simplifying assembly...
