Abstract

The invention provides a back frame of a flat panel display device. The back frame comprises main splicing pieces, auxiliary splicing pieces and a support for fixing a circuit board; the number of the main splicing pieces is at least two, the at least two main splicing pieces are connected in a splicing mode to form a main framework of the back frame, and the auxiliary splicing pieces are splicedwith the main framework; each part of different positions of the main framework is made of different materials according to the practical application; the back frame is provided with the support for fixing the circuit board; and the support comprises a support main body, a first suspension part, a first supporting part and a first elastic turnover part. The invention also provides a backlight system. According to the back frame and the backlight system, the back frame has a simple structure, the problem that the circuit board is difficult to fix is solved, and the cost of a back frame mold can be reduced; and the materials of the back frame are saved, so that the cost of the flat panel display device is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a back frame and a backlight system of a flat panel display device. 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. Such as figure 1 As shown, the back frames 10 in the prior art all adopt an integral back frame, and the integral bac...
