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

Embodiment Construction
[0049] See Figure 2-3 , figure 2 is a schematic structural diagram of a flat panel display device according to the first embodiment of the present invention, image 3 It is a schematic structural diagram of the back frame of the flat panel display device according to the second embodiment of the present invention. like figure 2 As shown, the flat panel display device 20 of this embodiment includes a backlight system 21 and a display panel 22 . The backlight system 21 is disposed on the back of the display panel 22 and provides a light source for the display panel 22 .
[0050] In this embodiment, the backlight system 21 includes a light source 25 , a uniform light mechanism 24 and a back frame 23 . The back frame 23 carries the light source 25 and the light homogenizing mechanism 24 . When the backlight system 21 is of the side light type, the uniform light mechanism 24 is a light guide plate; when the backlight system 21 is of the direct type, the uniform light mechani...

A back frame (23) of a flat panel display device (20) comprises at least two main splicing pieces (261, 262). The at least two main splicing pieces (261, 262) comprise splicing portions (2611, 2621). The at least two main splicing pieces (261, 262) are spliced and fitted to each other through corresponding splicing portions (2611, 2621) to form a main frame (27) of the back frame (23). The splicing portions (2611, 2621) of the at least two main splicing pieces (261, 262) are provided with fool-proofing structures fitted to each other. Also provided are a manufacturing method of the back frame (23) and a backlight system (21). In the back frame (23) of the flat panel display device (20), the manufacturing method of the back frame (23), and the backlight system (21), the structure is simple, the mold cost of the back frame can be reduced, the material of the back frame (23) can be saved to reduce the cost of the flat panel display device (20), and the fool-proofing design can be satisfied, thereby further reducing the misoperation and improving the production efficiency.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a back frame of a flat panel display device, a manufacturing method of the back frame and 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, and a lamp group. [0003] Currently, there are various sizes of display panels on the market to meet people's different needs. For example, in the field of television, the size of LCD panels includes 31.5, 42, 46, 48 or 55 inches, and different back frame molds need to be set according to different sizes of LCD panels. [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, the back frames 10 in the prior art all adopt an in...
