Yet its reflector plate 92 of above-mentioned traditional backlight module is the manufacturings that are separated from each other with the light cover 93 of both sides, so will increase processing procedure quantity, also increases the part number that uses, and relatively also can raise the cost, and is real non-very good.
Summary of the invention
Reflector plate structure of the present invention is to be mounted in the backlight module, and this backlight module includes a light guide plate and at least one light source, and reflector plate structure includes a reflector plate.
Above-mentioned reflector plate includes a bottom and at least one sidepiece, and at least one sidepiece wherein is to connect the bottom and extended laterally by the bottom, and at least one sidepiece is bent with an accommodation space and an opening.
Wherein, at least one light source of backlight module is to be placed in the accommodation space of at least one sidepiece of reflector plate and towards the open side bright dipping, and light guide plate is that bearing is on the bottom of reflector plate and be adjacent to opening.
Therefore, by by said structure, its can make reflector plate in the part of bearing light guide plate, with the whole structure that becomes one of part of ccontaining light source, so can reduce processing procedure number and part number, can reduce cost relatively.
At least one sidepiece and the place of interconnecting, bottom of above-mentioned reflector plate can include a folding line.Aforesaid folding line can include at least one empty cutter line or folding line and can include combination or the folding line that half breaking line at least or folding line can be empty cutter line and half breaking line and also can be other equivalent way.
In addition, above-mentioned light guide plate can include a light guide structure, and it can be positioned between reflector plate and light guide plate.Aforesaid light guide structure can include at least one leaded light point, and this at least one leaded light point is to be printed on the light guide plate by mode of printing.
In addition, above-mentioned reflector plate is can be made by polycarbonate (PC), certainly also can be made by polystyrene resin (ABS), methyl methacrylate (PMMA), styrene-methyl methacrylate resin (MS), tygon (PE), poly-third ethene (PS), polypropylene (PP), Polyvinylchloride materials such as (PVC).Except that aforementioned material, reflector plate also can be matrix, and to add 0.5～20% barium sulphate (BaSO4) more made, and perhaps reflector plate also can be matrix to add 1～5% monox (SiO2) more made.

Embodiment
Seeing also Fig. 2 is the cut-open view of the present invention's first preferred embodiment, wherein be shown in to organize in the backlight module 1 and be provided with reflector plate structure of the present invention, and backlight module 1 includes a light guide plate 11 and two light sources 12, and reflector plate structure then includes a reflector plate 2.
Please consult simultaneously top view that Fig. 2, Fig. 3 A are the reflector plates of the present invention's first preferred embodiment, and Fig. 3 B be the side view of Fig. 3 A, above-mentioned reflector plate 2 includes a bottom 21 and two sidepieces 22, two sidepieces 22 wherein are to lay respectively at bottom 21 two sides and be connected to bottom 21, and extended laterally by bottom 21 respectively, and two sidepieces 22 upwards bent inwards respectively an accommodation space 221 and an opening 222.
In present embodiment, reflector plate 2 is to be transparent material and made by polycarbonate (PC), certainly reflector plate 2 also can be transparent materials, and reflector plate 2 also can be made by polystyrene resin (ABS), methyl methacrylate (PMMA), styrene-methyl methacrylate resin (MS), tygon (PE), poly-third ethene (PS), polypropylene (PP), Polyvinylchloride materials such as (PVC).
In addition, in present embodiment, two sidepieces 22 of above-mentioned reflector plate 2 include a folding line 3 respectively with 21 places of interconnecting, bottom, this folding line 3 includes a plurality of empty cutter lines 31 respectively, two sidepieces 22 then can pass through the design by empty cutter line 31, and more easily upwards bent inwards respectively accommodation space 221 and opening 222.
In addition, two light sources 12 of above-mentioned backlight module 1 be placed in respectively in the accommodation space 221 of two sidepieces 22 of reflector plate 2, and respectively towards opening 222 side bright dippings, and light guide plate 11 is that bearing is on the bottom 21 of reflector plate 2 and be adjacent to the opening 222 of reflector plate 2.
In graphic, then include a light guide structure 111 between reflector plate 2 and light guide plate 11, this light guide structure 111 is to include a plurality of leaded light points 112 in present embodiment, and these a plurality of leaded light points 112 are to be printed on the light guide plate 11 with mode of printing.
Therefore, when two light sources 12 of backlight module 1 respectively during the opening 222 side bright dippings of two sidepieces 22 of orientating reflex sheets 2, light can be via bottom 21 reflections of reflector plate 2 and via the leaded light point 112 of light guide structure 111 and the guiding of light guide plate 11, make backlight module 1 produce light by this, and make backlight module 1 therefore produce Presentation Function.
About leaded light point 112 designs of light guide structure 111, but it is the light that mean allocation light source 12 is produced, and, does not have the problem that certain part is comparatively bright, certain part is darker and produces when making backlight module 1 produce Presentation Function by this.This part is not the technology emphasis of this case, so repeat no more in this.
Therefore, sharp by said structure, its can make reflector plate 2 in the part of bearing light guide plate 11, with the whole structure that becomes one of part of ccontaining light source 12, so can reduce processing procedure number and part number, can reduce cost relatively.
Please consult Fig. 4 A simultaneously and be the reflector plate of the present invention's second preferred embodiment top view, and Fig. 4 B be the side view of Fig. 4 A, its primary structure is all identical with above-mentioned first preferred embodiment, only difference is that the bottom 51 of reflector plate 5 and the folding line 4 at two sidepieces, 52 places of interconnecting include half breaking line 41 respectively, and this kind design also can make two sidepieces, the 52 easier bendings of reflector plate 5, that is the present invention's second preferred embodiment also can be reached the described various effects of above-mentioned first preferred embodiment.
The foregoing description only is to give an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
