Problems solved by technology

[0003] There is an existing backplane, which has developed a hollowed or spliced ​​backplane design in the overall backplane design, which reduces the cost to a certain extent, but the splicing or hollowing out reduces the strength of the backplane, which in turn causes the backplane to be fixed on the backplane. The PCB board is not easy to change

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0032] A liquid crystal display device includes a liquid crystal panel and a backlight module, and a back plate is arranged at the bottom of the backlight module. The backplane includes a frame 100 composed of a plurality of brackets 110 , and a plurality of bridges 120 are arranged on the frame 100 . Such as figure 1 As shown, the bracket 110 includes an upper bracket 111, a lower bracket 113, a left bracket 114, and a right bracket 112 connected end to end to form the large frame 100 of the entire backplane. The large frame 100 is also provided with two middle brackets 115, the middle Two ends of the bracket 115 are respectively fixed on the upper and lower brackets 110 . A plurality of bridging bridges 120 are provided on each bracket 110 and between two brackets 110 , and the bridging bridges 120 can be used to fix the PCB board and othe...

Abstract

The invention discloses a connecting piece, a back board and a liquid crystal display device. The connecting piece for a frame-type back board comprises at least two connecting parts which are respectively fixed with the support end parts of the frame-type backboard. Since the connecting piece is used for splicing supports, the connecting piece can be a high-strength structure which is integrally formed and the splicing strength of the supports is improved; since the connecting piece has a plurality of connecting parts and each connecting part is separately connected with one support, an interface can be standardized; and since the supports can be made into standard sections and cut according to different dimensions, the universality of the supports is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and more specifically, relates to a connector, a back plate 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 assembl...
