Referring to Fig. 3, it is the structural representation of optical diaphragm group 400 of this utility model one embodiment.
3rd side 430 of optical diaphragm group 400 and four side 440 are all not orthogonal to first side 410.Further
Ground, the angle between described 3rd side 430 and described four side 440 and the described first side 410 of optical diaphragm group 400
All not less than 105 °, to be further ensured that optical diaphragm group 400 will not be shifted over.Specifically, described 3rd side 430 and institute
State four side 440 to be symmetrical set, i.e. described 3rd side 430 and described four side 440 respectively with described first side
Angle between 410 is identical.Preferably, described 3rd side 430 and described four side 440 respectively with described first side
Angle between 410 is 105 °～120 °, to avoid optical diaphragm group 400 excessive to the increment of both sides, increases backlight module 10
The size of frame.
Further, the described first side 410 of described optical diaphragm group 400 be arranged in parallel with described second side 420,
And the width of described first side 410 is less than the width of described second side 420.In the present embodiment, described optical diaphragm group
400 be shaped as is trapezoidal, and the most wide at the top and narrow at the bottom is trapezoidal, owing to optical diaphragm group 400 first side 410 leads to second side 420
Cross the 3rd side 430 and four side 440 even transition, i.e. first side 410 uniformly to increase to the increment of both sides, without sudden change position
Put, easy shape by die-cutting, and without the corner location of sudden change on the 3rd side 430 and four side 440, it is to avoid turning bright line is asked
Topic, improves display effect.
Refer to Fig. 4, its structural representation coordinated for the optical diaphragm group 400 shown in Fig. 3 with glue frame 100.
The housing of glue frame 100 is in rectangular configuration, frame groove shape and the form fit of optical diaphragm group 400.At the present embodiment
In, frame groove shape and optical diaphragm group 400 are all trapezium structure wide at the top and narrow at the bottom.
Referring to Fig. 5, it is the structural representation of optical diaphragm group 400 of another embodiment of this utility model.
The described first side 410 of described optical diaphragm group 400 be arranged in parallel with described second side 420, and described
The width of one side 410 is symmetrical equal to the width of described second side 420, described 3rd side 430 and described four side 440
Arrange, and the length of the line of the midpoint of described 3rd side 430 and described four side 440 is more than described first side
410 and the width of described second side 420.Specifically, the 3rd side 430 reaches with the width of described four side 440 midpoint
To maximum.Referring to Fig. 5, described optical diaphragm group 400 is about in described 3rd side 430 and described four side 440
Line between point is symmetrical.Further, described 3rd side 430 and described four side 440 are arc.That is, optics
Diaphragm group 400 is the wine bucket-type of left and right circular arc, owing to optical diaphragm group 400 first side 410 and second side 420 are by the 3rd
Side 430 even transition, without mutated site, easy shape by die-cutting, and nothing on the 3rd side 430 and described four side 440
The corner location of sudden change, it is to avoid turning bright line problem, improves display effect.Correspondingly, the shape of described glue frame 100 frame groove with
Optical diaphragm group 400 is mated, and is also the wine bucket-type of left and right circular arc.

Rectangular configuration then.
Above-mentioned backlight module 10, owing to the 3rd side 430 is not orthogonal to described first side, and due to the 3rd side 430
And described four side 440 supports with glue frame 100 cell wall, when vibration test or actually used in, optical diaphragm group 400 can be by
Glue frame 100 blocks to get off, and is prevented effectively from optical diaphragm group 400 and shifts, and improves backlight module 10 top bright line existing
As, improve raising display effect, also improve the reliability of product simultaneously.
Additionally, due to optical diaphragm group 400 uniformly increases to the increment of both sides, without sudden change or corner location, it is easy to cross cutting
Molding, and do not have turning bright line, improve display effect.
Correspondingly, this utility model one embodiment additionally provides a kind of display device, and this display device can be mobile phone, put down
The undersized display device that plate etc. are common, it is also possible to be large-sized display device such as TV, computer monitor, this display fills
Put and include any one backlight module 10 above-mentioned；Such as, this display device includes above-mentioned any one backlight module 10 and liquid
LCD panel, described display panels is pasted with described backlight module 10 and is connected, such as, by both-sided adhesive glue even
Knot.The structure of this backlight module can refer to above-described embodiment, does not repeats them here.Naturally, showing due to the present embodiment
Showing device have employed the technical scheme of above-mentioned backlight module 10, and therefore this display device has that above-mentioned backlight module 10 is all of to be had
Benefit effect.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic executed in example is all described, but, as long as the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the common skill of this area
For art personnel, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into
Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
