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
[0053] 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 first embodiment of the back frame of the flat panel display device according to the second embodiment of the present invention. Such as 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.
[0054] In this embodiment, the backlight system 21 includes a light source 25, a light homogenization mechanism 24 and a back frame 23. Wherein, the back frame 23 carries the light source 25 and the light homogenization mechanism 24. When the backlight system 21 is of an edge light type, the light homogenization mechanism 24 is a light guide plate; when the backlight system 21 is a dire...

The invention provides a back frame of a panel display device. The back frame comprises at least two main splicers, wherein the two main splicers are spliced to form a main frame of the back frame; and the two main splicers are spliced by a plurality of disperse splice points. The invention also provides a manufacturing method of the back frame and a backlight system. The back frame, the manufacturing method and the backlight system have the following beneficial effects: the back frame mould has simple structure so that the cost of the back frame mould can be lowered; the materials of the back frame are saved to lower the cost of the panel display device; and pressure can be dispersed while the strength of the splice parts of the back frame is ensured, thus further ensuring the overall strength of the back frame to meet the requirement.
Description
Technical field [0001] The present 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. The backlight module includes a back frame, a reflective sheet, a light guide plate, and a lamp assembly. [0003] Currently, there are multiple display panel sizes on the market to meet people's different needs. For example, in the TV field, the size of liquid crystal panels includes 31.5, 42, 46, 48, or 55 inches, and different back frame molds need to be set according to different sizes of liquid crystal panels. [0004] See figure 1 , figure 1 It is a schematic diagram of the back frame structure of a liquid crystal display device in the prior art. Such as figure 1 As shown, the back frame 10 in the prior art adopts an integral ba...
