Below in conjunction with the accompanying drawing in the utility model embodiment, in the utility model embodiment
Technical scheme be clearly and completely described it is clear that described embodiment is only this
The a part of embodiment of utility model, rather than whole embodiments.Based in the utility model
Embodiment, those of ordinary skill in the art are obtained all under the premise of not making creative work
Other embodiment, broadly falls into the scope of the utility model protection.
In in figure, the similar unit of structure is represented with same-sign.
Refer to Fig. 3 and Fig. 4, Fig. 3 is the preferred embodiment of backlight module of the present utility model
The top view of structural representation, Fig. 4 is the sectional view along the b-b ' section line in Fig. 3.
The utility model provides a kind of technical scheme: a kind of backlight module, described backlight module bag
Include glue frame 21, shading film 22, blooming piece 23, light guide plate 24, base plate 25, two-sided
Glue 26 and light source 27.
Light guide plate 24 is arranged on base plate 25, and fixing by glue frame 21, described blooming piece
In 23 light-emitting areas being arranged on light guide plate 24, shading film 22 and blooming piece 23 are taken
Connect region.Wherein shading film 22 is border shape, and glue frame 21 passes through double faced adhesive tape 26 and base plate
25 paste fixation.
The length of blooming piece 23 and the wide length being respectively greater than light guide plate 24 and width, such blooming
Piece 23, light guide plate 24 and base plate 25, three can be formed by a groove, under glue frame 21
Partial widened section is located in this inside grooves.
The operation principle of backlight module of the present utility model:
First switch on power, light source 27 launches light, injects leaded light from the incidence surface of light guide plate 24
Inside plate 24, then side light source is converted into area source by light guide plate 24 again, penetrates from light-emitting area
Go out.
The light projecting from light guide plate 24 light-emitting area is processed by blooming piece 23, thus carrying
The positive brightness of high backlight module, and the overlap joint that blooming piece 23 and shading film 22 are formed
The light spilling from blooming piece 23 surrounding can be blocked by region, prevent backlight module because
Light leak and bright border occurs.
So complete the course of work of backlight module of the present utility model.
The backlight module of this preferred embodiment is widened by making under glue frame 21 partly inwardly side, but
Other positions of glue frame 21 are constant, and reduce the size of light guide plate 24, thus can be not
In the case of changing backlight module size and viewing area size, increase glue frame as far as possible
21 and the bonding area of base plate 25, thus the bigger double faced adhesive tape of usable floor area 26, to ensure glue
Frame can firmly be pasted and fixed on base plate 25.And, increase glue frame 21 as far as possible
Width is it is also possible to effective glue frame 21 that prevents deforms.
The utility model also includes a kind of liquid crystal indicator, and it includes display floater, and the back of the body
Light module；Described backlight module includes glue frame 21, shading film 22, blooming piece 23, leads
Tabula rasa 24, base plate 25, double faced adhesive tape 26 and light source 27.
Light guide plate 24 is arranged on base plate 25, and fixing by glue frame 21, described blooming piece
In 23 light-emitting areas being arranged on light guide plate 24, shading film 22 and blooming piece 23 are taken
Connect region.Wherein shading film 22 is border shape, and glue frame 21 passes through double faced adhesive tape 26 and base plate
25 paste fixation.
The length of blooming piece 23 and the wide length being respectively greater than light guide plate 24 and width, such base plate
25th, light guide plate 24 and blooming piece 23, three just stacks successively and can be formed by a groove,
The widened section of 21 times parts of glue frame is located in this inside grooves.
The operation principle of liquid crystal display of the present utility model:
First switch on power, light source 27 launches light, injects leaded light from the incidence surface of light guide plate 24
Inside plate 24, then side light source is converted into area source by light guide plate 24 again, penetrates from light-emitting area
Go out.
The light projecting from light guide plate 24 light-emitting area is processed by blooming piece 23, thus carrying
The overlap joint that the positive brightness of high backlight module, wherein blooming piece 23 and shading film 22 are formed
The light spilling from blooming piece 23 surrounding can be blocked by region, prevents liquid crystal display from filling
Put and bright border occurs because of light leak.From display floater will be modulated from the light that backlight module sends again
Reason, thus obtain the picture of needs.
So complete the course of work of liquid crystal indicator of the present utility model.
The liquid crystal indicator of this preferred embodiment is widened by making under glue frame 21 partly inwardly side,
But other positions of glue frame 21 are constant, and reduce the size of light guide plate 24, thus can be
In the case of not changing liquid crystal indicator size and viewing area size, increase as far as possible
Glue frame 21 and the bonding area of base plate 25, thus the bigger double faced adhesive tape of usable floor area 26, with
Ensure that glue frame can firmly be pasted and fixed on base plate 25.And, increase glue as far as possible
The width of frame 21 is it is also possible to effective glue frame 21 that prevents deforms.
The backlight module of this preferred embodiment and its liquid crystal indicator, by reducing light guide plate
24 size, and so that glue frame 21 half part is widened to inner side, to increase the width of glue frame 21,
Thus increasing the bonding area of glue frame 21 and base plate 25, thus do not change backlight module and its
It is ensured that glue frame 21 can be fixed in the case of liquid crystal indicator size and viewing area size
It is pasted onto on base plate 25；And by increasing the thickness of glue frame 21 so that glue frame 21 is not easy
Deform.
In sum although the utility model is disclosed above with preferred embodiment, but above-mentioned excellent
Select embodiment and be not used to limit the utility model, those of ordinary skill in the art, do not taking off
In spirit and scope of the present utility model, all can do various change and retouching, therefore this practicality
New protection domain is defined by the scope that claim defines.
