Screen metal frame assembly and liquid crystal display device

Abstract

An embodiment of the invention provides a screen metal frame assembly and a liquid crystal display device, relates to the field of display screen assembling and solves the problem of splicing errors of a screen metal frame. The screen metal frame assembly comprises a first frame and a second frame, wherein a first splicing surface formed at one end of the first frame is correspondingly attached to a second splicing surface formed at one end of the second frame; an elastic piece is arranged at one end, close to the first splicing surface, of the inner wall bottom surface of the first frame; one end of the elastic piece is attached to the inner wall bottom surface of the first frame; the other end of the elastic piece is connected with the inner wall bottom surface of the second frame. The screen metal frame assembly and the liquid crystal display device are applied to metal frame splicing of the liquid crystal display screen.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a screen metal frame assembly and a liquid crystal display device. Background technique [0002] At present, with the continuous development of liquid crystal display production technology, liquid crystal display devices gradually tend to narrow bezels, and further develop towards ultra-narrow bezels. Previous products have wider bezels, which affect visual effects. And as figure 1 As shown, the current ultra-thin liquid crystal display industry adopts a metal four-segment splicing scheme that can meet the requirements of the appearance and ultra-thin trend of liquid crystal display devices; 1 and the splicing of the left frame 2 / right frame 3 and the splicing of the lower frame 4 and the left frame 2 / right frame 3) will directly affect the appearance of the product and the complexity of the product assembly process, from cost, installation, From various perspectives such as appe...

Problems solved by technology

[0003] Refer to as figure 2 As shown, when splicing the metal splicing front frame and the liquid crystal module at present, the upper frame 1 and the side frame ( figure 2 The middle is the left frame 2) During the splicing process, flash seams 5 will be produced due to the deformation of stainless steel, and because the splicing of the upper frame 1 and the side frame in the prior art mainly depends on figure 2 The middle fixing part 6 is fixed on the liquid crystal display module so as to achieve the splicing effect, and it is easy to produce such as figure 2 The step difference 7 in the front and back direction, A in the figure is the top view enlarged view of the step difference 7

[0004] In addition, refer to as image 3 As shown, when splicing the metal splicing front frame and the liquid crystal display module at present, the lower frame 4 and the side frame ( image 3 The middle is the left frame 2) During the splicing process, the lower frame 4 is attached to the LCD module by screws. Since the lower surface of the LCD module may have an outwardly inclined surface during the manufacturing process, the lower frame 4 is locked by screws. When it is fixed on the liquid crystal display module, the area I of the lower frame 4 will be flipped forward along the inclined surface, and the corresponding area II of the lower frame 4 will also collapse backward; at the same time, because the screw locking process may make the lower frame 4 relatively The normal assembly position is upward so that the splicing end of the side frame and the lower frame 4 produces a step difference in the up and down direction as shown by arrow C and arrow D

[0005] Therefore, there are splicing errors in the assembly scheme of the screen front frame assembly in the prior art, which will cause appearance defects of the liquid crystal display
