like figure 1 As shown, the back frames 10 in the prior art all adopt an integral back frame, and the integral back frame 10 is usually produced by metal stamping or plastic injection. The integral back frame 10 needs to consume too much material, and the material cost is high.
In addition, the large-sized back frame 10 needs to use relatively large stamping equipment, and the mold corresponding to the back frame 10 has a large size and complex structure, and the cost of the back frame mold is high.
Therefore, the cost of the back frame of the prior art is high

The invention provides a manufacturing method of a back frame of a panel display device. The method comprises the following steps: manufacturing at least two main splicing elements of the back frame; overlapping a part of one main splicing element on the other main splicing element; and carrying out atresia riveting directly on parts of the two overlapped main splicing elements so as to splice the two main splicing elements. The invention also provides a manufacturing method of the backlight system of the panel liquid crystal display device. The manufacturing method of the back frame and the backlight system provided by the invention are good for production manufacturing, and man hour and man power are saved; and simultaneously a splicing method is adopted for the back frame, thus the mold of the back frame is simple in structure, thus the cost of the mold of the back frame can be lowered, and also the materials of the back frame are saved, so that the cost of the panel display device is lowered.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a back frame of a flat panel display device and a manufacturing method of a backlight system. Background technique [0002] In the prior art, a liquid crystal display device includes a front frame, a panel, and a backlight module, wherein the backlight module includes a back frame, a reflection sheet, a light guide plate, a lamp group, and the like. [0003] Currently, there are various display panel sizes on the market to meet people's different needs. For example, in the field of TV, the size of the liquid crystal panel includes 31.5, 42, 46, 48 or 55 inches, and different back frame molds need to be set according to the liquid crystal panel of different sizes. [0004] See figure 1 , figure 1 It is a schematic diagram of the structure of the back frame of the liquid crystal display device in the prior art. like figure 1 As shown, in the prior art, the back f...
