Further, described light source comprises LED lamp bar, and described LED lamp bar comprises:
Be fixed on the pcb board of display device housing;
LED lamp, is evenly arranged at the two sides that described pcb board is relative, and described first side of described LED lamp and corresponding described LGP is oppositely arranged.
Further, the material of described pcb board adopts aluminium, glass-epoxy, polyimides or polyester film.
Further, described light source comprises the LED lamp that embeds described the first side.
The utility model also provides a kind of display device, comprises display floater and above-mentioned backlight.
The utility model also provides a kind of display device, comprises multiple display floaters of splicing mutually and above-mentioned backlight, and light source is corresponding to the non-display area of display floater.
The beneficial effects of the utility model are: between the LGP of adjacent two splicings, light source is set, saves space, be conducive to realize narrow frame and the slimming of mosaic screen product.
Brief description of the drawings
Fig. 1 represents side-edge type backlight structural representation in prior art;
Fig. 2 represents direct backlight source structure schematic diagram in prior art;
Fig. 3 represents the utility model back light source structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present utility model and principle are elaborated, illustrated embodiment, only for explaining the utility model, not limits the protection domain of this practical information with this.
As shown in Figure 3, the present embodiment provides a kind of backlight, comprises multiple LGPs 1 of splicing mutually, also comprises the light source 2 between adjacent described LGP 1.
With respect to side-edge type backlight of the prior art and direct-light-type backlight, in the present embodiment, between the LGP 1 of an adjacent company splicing, light source 2 is set, save space, be conducive to realize narrow frame and the slimming of mosaic screen product, and reduced cost.
In order to prevent occurring dark space on display screen, described in each, LGP 1 comprises the front as exiting surface, and as the first side 11 incidence surface, that be oppositely arranged with described light source 2, all the other sides are coated with reflectance coating.
Described LGP 1 can be that rectangle also can be for other shapes, corresponding, also can have multiple again as incidence surface as the shape of described first side 11 of Mosaic face simultaneously.
The version of described light source 2 can have multiple, below the version of several light sources 2 in the present embodiment.
In one embodiment, described light source 2 comprises 22, LED lamp, and 22, described LED lamp comprises:
Be fixed on the pcb board 21 of backboard;
LED lamp 22, is evenly arranged at the relative two sides of described pcb board 21, and described LED lamp 22 is oppositely arranged with described first side 11 of corresponding described LGP 1.
Pcb board 21 printed on both sides circuits, the two-sided LED lamp 22 that arranges, 22, the LED lamp with above-mentioned pcb board 21 is fixed on to backboard, and arranges between adjacent described LGP 1, be arranged at the splicing seams place of adjacent described LGP 1, with respect to direct-light-type backlight of the prior art, needn't be subject to the restriction of mixed light height, side-edge type backlight compared to existing technology, utilize the splicing seams between adjacent splicing LGP 1 that light source 2 is set, save space, strong in narrow frame design and the slimming of product.
In one embodiment, described light source 2 comprises 22, LED lamp, and 22, described LED lamp comprises:
Be fixed on the pcb board 21 of display device housing;
LED lamp 22, is evenly arranged at the relative two sides of described pcb board 21, and described LED lamp 22 is oppositely arranged with described first side 11 of corresponding described LGP 1.
Described light source 2 adopts the version of 22, LED lamp, and in the two-sided version that LED is set of a pcb board 21, realize narrow frame design, 22, LED lamp can be fixed on backboard, can be fixed on display housing, certainly can also be fixed in other structures, only have and realize the fixing of 22, LED lamp.
