Abstract

The invention relates to a backlight pattern assembly which includes at least: a back board; a protuberance structure mounted on the surface of back board, and forms a holding space with the back board; and a base plate mounted between the holding spaces to protect the base plate. The invention contain a protuberance structure to protect the foundation plate, the protuberance structure is an embossment and guard board with L shape, and integrate with the surface of back board, when the foundation plate are mounted in the holding spaces under the protuberance structure of back board that can be protected by the protuberance structure, and make the base plate avoid the damage caused by collision when assembling it. Because the protuberance structure is integral with the surface of back board, it can save adding the protecting cover, save cost, decrease the efficiency of collision effectively, and the side space of back board can be used effectively for other designing or save the side space of backlight pattern assembly, and it's very useful.

Description

technical field

[0001] The invention relates to a backlight module, in particular to a backlight module with a raised structure protecting a common-ground substrate to prevent the common-ground substrate from being damaged by collision during assembly. Background technique

[0002] Nowadays, thin film transistor liquid crystal display (TFT-LCD) design focuses on concepts such as lightness, thinness and shortness. , in order to effectively use the side space of the backplane without designing the common ground board on the side, the common ground board is arranged on the back of the backplane, and it is less inclined to set it on the side of the aluminum backplane, please refer to figure 1 As shown in FIG. 1 , it is a schematic diagram of a conventional common-ground substrate arranged on the back of the backplane, which is mainly for effectively saving the space on the side of the backlight module 100 .

[0003] As mentioned above, the common ground substrate 120 of the kno...
