In addition, above-mentioned fluorescent tube adjacent electrode group, and these two parts of electrode group because near power supply unit, therefore fluorescent tube adjacent electrode group with the electrode group, reach heat that power supply unit produced will cause backboard this side of power supply unit temperature higher, can influence the quality of backlight module integral body equally.
Summary of the invention
The object of the present invention is to provide a kind of back board structure group to be located on the display device, this display device includes a backboard, a fluorescent tube, a display screen and a power supply unit, its dorsulum includes a upper surface and a lower surface, the power supply unit group is located at the lower surface of backboard, light tube group is located at the upper surface of backboard, and fluorescent tube includes a front portion, this anterior front end is provided with an electrode group, while front portion and electrode group are respectively corresponding to power supply unit, and the display screen group is located at the upper surface and the cover cap fluorescent tube of backboard.
Offer a perforate on the described backboard of the present invention, and described perforate is corresponding to the front portion of fluorescent tube and electrode group and corresponding to power supply unit.
Therefore, the perforate that backboard is offered can make this backboard in the front portion of fluorescent tube, the electrode group, can reduce the generation of leakage current with the power supply unit place, and the position of opening of offering at backboard, concentration phenomenon can not take place in the front portion of fluorescent tube, electrode group, the heat that is produced with power supply unit, be that backboard can effectively reduce temperature at aforementioned position, improve the briliancy and the quality of display device integral body.
Described fluorescent tube becomes the U font and is formed with two straight sections, and the front portion of described fluorescent tube is formed on two straight sections, and the electrode group also can be formed on two straight sections.
In addition, above-mentioned backboard can include a base plate and a reflector, and wherein reflector is folded is located on the base plate, and the upper surface of backboard is formed on the reflector, and the lower surface of backboard is formed on the base plate.And the perforate of backboard is opened on the base plate of backboard, and light tube group is located on the reflector of backboard, and simultaneously, perforate can be a microscler perforate or circle, square, and other shape, i.e. the shape of perforate is not limited.
In addition, above-mentioned power supply unit also includes an assembled plate, and the assembled plate group is located at the lower surface of backboard.And display device can be a LCD TV.

Perforate 113 fluorescent tubes 12 front portions 121
Embodiment
Please consult simultaneously Fig. 1 three-dimensional exploded view of the present invention, another visual angle of Fig. 2 the present invention three-dimensional exploded view, and Fig. 3 be sectional view of the present invention, one display device 1 is wherein arranged, in the present embodiment, display device 1 is a LCD TV, and it includes a backboard 11, a plurality of fluorescent tube 12, a display screen 13 and a power supply unit 14.
Described backboard 11 is formed by a base plate 101 and folded each other the establishing of a reflector 102, and be formed with on the reflector 102 on a upper surface 111, the base plate 101 and be formed with a lower surface 112,14 groups of power supply units be located at backboard 11 base plate 101 more than 112 fluorescent tube 12 of lower surface then group be located on the upper surface 111 of reflector 112 of backboard 11.
In the present embodiment, above-mentioned power supply unit 14 includes an assembled plate 141, and therefore 141 groups of lower surfaces 112 that are located at the base plate 101 of backboard 11 of assembled plate can be located at power supply unit on the lower surface 112 for 14 groups.
In addition, 12 one-tenth U fonts of each fluorescent tube of described a plurality of fluorescent tube 12 also are formed with two straight sections 123, and on two straight sections 123, be formed with a front portion 121 and an electrode group 122 respectively, wherein electrode group 122 is arranged on anterior 121 front end and contiguous anterior 121, and front portion 121 corresponds respectively to power supply unit 14 with electrode group 122, so, the electric current that power supply unit 14 produces can be passed on the fluorescent tube 12 by electrode group 122, makes fluorescent tube 12 luminous.
In addition, 13 groups of upper surface 111 and a plurality of fluorescent tubes 12 of cover cap that are located at the reflector 112 of backboard 11 of display screen are assembled into a display device 1.
Please note, offer a plurality of perforates 113 on the backboard 11 of display device 1, the quantity of perforate 113 is corresponding with the straight sections 123 of each fluorescent tube 12 of a plurality of fluorescent tubes 12, in the present embodiment, a plurality of perforates 113 are opened on the base plate 101 of backboard 11, and a plurality of perforates 113 are a microscler perforate, and simultaneously, these a plurality of perforates 113 correspond respectively to the front portion 121 of each fluorescent tube 12, the electrode group 122 and the power supply unit 14 of each fluorescent tube 12.
Therefore, design by perforate 113, make backboard 11 in the front portion 121 of contiguous each fluorescent tube 12, the electrode group 122 of each fluorescent tube 12, reduce with the leakage current at the position of power supply unit 14, and the situation that the front portion 121 of each fluorescent tube 12 at aforementioned position, the electrode group 122 of each fluorescent tube 12, the heat that is produced with power supply unit 14 also can not be concentrated, be that backboard 11 can effectively reduce its temperature at aforementioned position, improve the briliancy and the quality of display device 1 integral body.
