Description

Display backshell liquid crystal display Technical Field The utility model relates to the technical field of display equipment, in particular to a rear shell of a display and a liquid crystal display. Background In the fields of consumer electronics, commercial display, industrial control, and the like, liquid crystal displays are widely used as key display devices. With the increasing demand of various industries for display devices, the production scale of liquid crystal displays is continuously expanding, and higher demands are put on the production efficiency and the assembly convenience of the liquid crystal displays. The rear shell in the liquid crystal display is used as an outer protective shell and mainly has the functions of protecting internal components, bearing appearance design (such as modeling and color matching), reserving an interface opening and the like. The back plate is an internal core supporting component and is usually made of metal (such as aluminum alloy and steel plate) or high-strength engineering plastic, and provides a mounting base surface for a liquid crystal panel, a backlight module, a driving circuit board and the like, so that the position of an internal component is ensured to be fixed. Correspondingly, in the process of assembling the liquid crystal display, the connection of the rear shell and the backboard is an important link. At present, a bolt or a buckle structure is commonly adopted in the industry to realize the connection of the two. The bolt structure is required to be provided with corresponding screw holes on the rear shell and the back plate respectively, and the fixing is completed by penetrating bolts through the screw holes and tightening the bolts. In practical production operations, it has been found that the assembly process of such a bolt structure is relatively complex. During assembly, screw holes are required to be accurately aligned, and then screwing operation is performed, so that more time and labor are consumed, and certain requirements are also met for the proficiency of operators. In large-scale production lines, complex assembly processes tend to impact overall production efficiency. In addition, in the large-size liquid crystal display, although the back shell and the back plate can be connected through the buckle structure, a plurality of buckles are arranged at the edge due to the large size of the back shell, and the corresponding deviation of the positions of the buckles is easy to occur due to the influence of the processing precision, the rigidity of materials and the deformation in the assembly process, so that the alignment of each buckle needs to be repeatedly adjusted during the buckling, the operation steps and the time cost are increased, and the high-efficiency assembly requirement is difficult to meet in the large-scale production. Therefore, the above-described problems are to be solved.
