Embodiment
For reaching the employed technological means of purpose and effect, and following graphic cited embodiment only is aid illustration hereinafter with reference to the graphic the present invention of description who encloses, and in order to understanding, but that the technological means of this case is not limited to is cited graphic.
Please refer to Fig. 2 and Fig. 3, Fig. 2 is the synoptic diagram of backlight module of the present invention.Fig. 3 be among Fig. 2 backlight module along the HH cross-sectional schematic.Provide a kind of backlight module 200 in present embodiment, it comprises the back of the body frame 20, reflector plate 21 and fluorescent tube 22.This back of the body frame 20 comprises base plate 20a and side plate 20b.This reflector plate 21 comprises the first reflecting part 21a and the second reflecting part 21b, this second reflecting part 21b offers the first containing hole 211a and the second containing hole 211b, this first containing hole 211a and this second containing hole 211b extend to this second reflecting part 21b from the junction 213 of this first reflecting part 21a and this second reflecting part 21b respectively, has a kerf 214 between this first containing hole 211a and this second containing hole 211b, this otch 214 is better is joint-cutting between this first containing hole 211a and this second containing hole 211b, in other words, namely form otch 214 along cutting between this first containing hole 211a and this second containing hole 211b.This fluorescent tube 22 comprises the first straight tube 22a, the second straight tube 22b and connects this first straight tube 22a and the bottom tube 22c of the second straight tube 22b, and this first straight tube 22a is parallel to this second straight tube 22b, and this first straight tube 22a is perpendicular to this bottom tube 22c.When carrying out the backlight module assembling, with this first reflecting part 21a and this second reflecting part 21b along these junction 213 bendings, the lower limb 213b of this first reflecting part 21a and this otch 213 is arranged on this base plate 20a, this second reflecting part 21b is connected to this side plate 20b obliquely, because the coboundary 214a of this otch 214 and the lower limb 214b of this otch 214 separate, the coboundary 214a of this otch 214 is a bit larger tham or equals the diameter of this fluorescent tube 22 to the distance H 1 of this base plate 20a, again this bottom tube 22c is inserted between this back of the body frame 20 and this reflector plate 21 from this otch 214, this first straight tube 22a is placed in this first containing hole 211, and this second straight tube 22b is placed in this second containing hole 212.Because the coboundary 214a of this otch 214 is a bit larger tham or equals the diameter of this fluorescent tube 22 to the distance H 1 of this base plate 20a, therefore this bottom tube 22c be need not reflector plate is pulled upwardly along otch when this otch 214 is inserted between this back of the body frame 20 and this reflector plate 21, when having avoided assembling backlight module in the prior art reflector plate pull-up is produced the problem of folding line.
Please refer to Fig. 3, as optional technical scheme, the coboundary 214a of this otch 214 has orthogonal projection line 215 on this base plate 20a, and the lower limb 214b of this otch 214 is between this side plate 20b and this projection line 215.The lower limb 214b of above-mentioned reflector plate extends between this side plate 20b and this projection line 215, increases the volume reflection of light, can further promote the optical quality of backlight module.In addition, in present embodiment, the width of this first containing hole 211a and this second containing hole 211b equals respectively the diameter of this first straight tube 22a and this second straight tube 22b.Spacing between this first containing hole 211a and this second containing hole 211b equals the length of this bottom tube 22c.As shown in Figure 2, this reflector plate can further include many this first containing hole of group 211a, this second containing hole 211b and otch 214.
According to an embodiment, the invention provides a kind of display device, it comprises above-mentioned backlight module 200.
Compared to known techniques, the coboundary of the otch on its reflector plate of backlight module of the present invention arrives the distance of this base plate more than or equal to the diameter of this fluorescent tube, make things convenient for fluorescent tube to be inserted between this back of the body frame and this reflector plate from this otch, and can not produce folding line, improved the optical quality of backlight module.In addition, the lower limb of reflector plate extends lengthening to this side plate direction, can further promote the optical quality of backlight module.
Only the above person only is embodiments of the invention, when not limiting the scope that the present invention is implemented with this.The equalization of namely generally doing according to the present patent application claim changes and modifies, and all should still belong to the scope that patent of the present invention contains.
