BACKBOARD SPLICING STRUCTURE OF LARGE-SIZE BACKLIGHT MODULE, AND LIQUID CRYSTAL DISPLAY APPARATUS

摘要

A backboard splicing structure of a large-size backlight module. A backboard comprises a bottom flat plate (10), and a splicing piece (20) spliced on an end side of the bottom flat plate (10). The splicing piece (20) comprises a side plate (22), and an upper support plate (23) and a lower support plate (21) both disposed on a same side of the side plate (22) and perpendicular to the side plate (22). A lower bottom surface of the upper support plate (23), an upper top surface of the lower support plate (21) and the side plate (22) form a clamping mouth (24) used for clamping the bottom flat plate (10). Column groove assembling structures are disposed on the lower bottom surface of the upper support plate (23) and the bottom flat plate (10). Fastening screws are disposed between the bottom flat plate (10) and the splicing piece (20). By using the backboard splicing structure of the large-size backlight module, that fixing in the two-dimensional direction of the three-dimensional direction is implemented, and fixing in the third-dimensional direction is implemented by using fewer screws, so that the objective of the fastened mounting is achieved, working procedures are reduced, consumed screws are greatly reduced, the time consumed in the assembly is shortened, and the labor efficiency is improved.
