In the accompanying drawings, identical part uses identical reference.Accompanying drawing is not according to actual ratio.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As illustrated in figs. 1 and 2, in the prior art, double faced adhesive tape 1 is from top to bottom bonded glue frame 2 and reflector plate 3, due to
Needing to stay certain gap 4 on the adjacent both sides of reflector plate 3 between the double faced adhesive tape 1 adhered to, (purpose is to prevent reflector plate 3 from producing ripple
Unrestrained warpage) double faced adhesive tape 1, then, will be between double faced adhesive tape 1 and glue frame 2 after the completion of assembling bonding with certain thickness in addition
Form a gap 4.During this backlight module use, steam and dust will be directly entered inside backlight from gap 4, this
The display effect of display can be had a strong impact on, is produced bad.
The invention provides a kind of stop member for backlight module, Fig. 3, Fig. 4 and Fig. 5 are seen, it is anti-including standby glue
Piece and glue frame 2 are penetrated, standby glue reflector plate includes reflector plate 3 and the double faced adhesive tape 1 adhered to along four sides of reflector plate 3；Double faced adhesive tape 1 is by up to
Lower bonding glue frame 2 and reflector plate 3；Glue frame 2 is provided with barricade 5, the seam of the double faced adhesive tape 1 of standby glue reflector plate at the gap 4 of double faced adhesive tape 1
Breach 6 is provided with gap 4, barricade 5 can extend into breach 6.
Barricade 5 in the present invention is independently darted on glue frame 2, and the gap 4 of the double faced adhesive tape 1 after assembling
Place, effect is that gap 4 is blocked.Standby glue reflector plate cuts out a breach 6 at the gap 4 of double faced adhesive tape 1, and breach 6 can
To put down the barricade 5 of glue frame 2.The shape phase interworking of the barricade 5 being located in glue frame 2 assembled and the breach 6 of standby glue reflector plate
Close, so as to form the barrier structure in the gap 4 for stopping double faced adhesive tape 1 so that steam and dust cannot directly enter backlight module
Inside, therefore serve the effect of water proof and dust proof.
See that the thickness of barricade 5 in Fig. 3 and Fig. 4, preferred embodiment is equal to the thickness of double faced adhesive tape 1.
The fit shapes of barrier structure can have various deformation, and feature is with independent barricade 5 and standby glue reflector plate
Breach 6, and barricade 5 and breach 6 are all at the gap 4 of double faced adhesive tape 1.
As shown in Fig. 5, Fig. 7 and Fig. 9, the level cross-sectionn of breach 6 is arc, rectangle or it is trapezoidal in one kind.With lacking
The level cross-sectionn of mouthfuls 6 barricades 5 being engaged is arc, rectangle or it is trapezoidal in one kind；As shown in Fig. 6, Fig. 8 and Figure 10,
Or the level cross-sectionn for the barricade 5 being engaged with breach 6 be arc, rectangle or it is trapezoidal with rectangular combined shaped in one
Kind.
The first gap W1 is provided between barricade 5 and breach 6；When the level cross-sectionn for the barricade 5 being engaged with breach 6 is arc
Shape, rectangle or it is trapezoidal with rectangular combined shaped in it is a kind of when, the edge of rectangular long side and adjacent reflector plate 3 it
Between be provided with the second gap W2.
The first gap W1 width is equal with the second gap W2 width in preferred embodiment.
By setting the first gap W1 and the second gap W2, it may be such that steam and dust access path are more tortuous, and its is straight
The access path connect is sheltered from by barricade 5 so that inside steam and the more difficult entry of backlight of dust.
Present invention also offers a kind of backlight module, stop member as described above is contained.
Stop member proposed by the present invention can play the function of water proof and dust proof from functional perspective, and can anti-leak-stopping
Light；From processing procedure angle, processing procedure is not interfered with；From a cost perspective, cost is not interfered with.Backlight mould is added on the whole
The reliability percent of pass of group.
Although by reference to preferred embodiment, invention has been described, is not departing from the situation of the scope of the present invention
Under, various improvement can be carried out to it and part therein can be replaced with equivalent.Especially, as long as in the absence of structure punching
Prominent, the every technical characteristic being previously mentioned in each embodiment can combine in any way.The invention is not limited in text
Disclosed in specific embodiment, but all technical schemes including falling within the scope of the appended claims.
