Back frame and backlight system

Abstract

The invention provides a back frame of a flat display device, comprising at least two main splicing pieces, auxiliary splicing pieces and an adjustable bracket; the at least two main splicing pieces are connected in a splicing way to form a main frame of the back frame, and the auxiliary splicing pieces are spliced with the main frame; the main frame is made of different materials at different positions of the main splicing pieces according to actual application; and the back frame is also provided with a bracket fixed together with the main splicing pieces or the auxiliary splicing pieces, and at least two selectable fixed points are arranged between the bracket and each main splicing piece or each auxiliary splicing piece so that the bracket is selectively arranged at different positions of the back frame. The invention also provides a backlight system. The back frame and the back frame of the backlight system provided by the invention are simple in structure, the cost of a back frame mould can be reduced, and the material of the back frame can be saved so that the cost of the flat display device can be reduced and different installation requirements can be met.

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...

Problems solved by technology

In the cost of the backplane, the cost of raw materials accounts for the largest proportion. If the backplane is all made of aluminum, the cost will be too high and the structural strength will be poor; if all the backplanes are made of galvanized steel, the heat dissipation will not be good and the product performance will be reduced.
