First Claim
1. A flat panel display device, comprising a backlight system and a display panel, wherein:
- the backlight system comprises a light source, a light homogenization mechanism, and a back frame;
the back frame carries the light source and the light homogenization mechanism, the light homogenization mechanism guiding light from the light source to a light incidence surface of the display panel;
the back frame comprises primary assembling pieces and secondary assembling pieces;
the primary assembling pieces are of a number of at least two, the at least two primary assembling pieces being directly joined end-to-end with each other to form a closed main frame structure of the back frame and define a first opening, the closed main frame structure surrounding the first opening;
the secondary assembling pieces are arranged inside the first opening and joined to the primary assembling pieces to divide the first opening into a plurality of small second openings;
some of the primary assembling pieces and the secondary assembling pieces are of first density and first strength and others are of second density and second strength;
the first density is greater than the second density and the first strength is greater than the second strength; and
wherein the at least two primary assembling pieces comprise first and second primary assembling pieces that are joined to each other, in which the first primary assembling piece has one end having a surface forming at least two joint sections that are arranged to space from each other in a lengthwise direction of the first primary assembling piece, each of the at least two joint sections has a structure mating one corresponding end of the second primary assembling piece, the corresponding end of the second primary assembling piece is selectively joined to a first one or a second one of the at least two joint sections of the first primary assembling piece, and other joint sections of the first primary assembling piece are idle, such that the second primary assembling piece is connected to the first primary assembling piece in a position-adjustable manner to respectively define a first size or a second size of the closed main frame structure of the back frame, where the first size is different from the second size.
