Brief description of the drawings
The following description carried out in conjunction with the accompanying drawings, above and other aspect, feature and the advantage of embodiments of the invention
It will become clearer, in accompanying drawing：
Fig. 1 is the structural representation of fluorescent powder film component according to an embodiment of the invention.
Embodiment
Hereinafter, with reference to the accompanying drawings to embodiments of the invention are described in detail.However, it is possible to come in many different forms real
Apply the present invention, and the specific embodiment of the invention that should not be construed as limited to illustrate here.Conversely, there is provided these implementations
Example is in order to explain the principle and its practical application of the present invention, so that others skilled in the art are it will be appreciated that the present invention
Various embodiments and be suitable for the various modifications of specific intended application.In the accompanying drawings, for the sake of clarity, element can be exaggerated
Shape and size, and identical label will be used to indicate same or analogous element all the time.
The embodiment provides a kind of backlight module, and it includes blue-ray LED, is arranged on the blue-ray LED side
Light guide plate, the optical diaphragm assembly being arranged on above light guide plate, and it is arranged on the fluorescent powder film above optical diaphragm assembly
Component；Wherein, optical diaphragm assembly includes the blooming pieces such as some polaroids, blast piece.As can be seen here, the backlight module is one
Kind side backlight module, here is omitted for the concrete structure of the backlight module, and those skilled in the art can refer to existing skill
Any one side backlight module in art.
In the present embodiment, be particularly it is to be noted that fluorescent powder film component in above-mentioned backlight module；Below with reference to
The fluorescent powder film component is described in detail accompanying drawing.
As shown in figure 1, the fluorescent powder film component includes fluorescent powder film 1 and is arranged on the top of fluorescent powder film 1
Layered optical diaphragm 2, wherein, the adjacent optical diaphragm unit of fluorescent powder film 1 is set；In Fig. 1, arrow represents the transmission side of light
To.
Specifically, the blue light sent with blue-ray LED can be sent by, which being filled with fluorescent powder film 1, forms the mutual of white light
The complementary colored particle 11 of light filling；The layered optical diaphragm 2 selectively can reflect blue light and be back to fluorescence through the complementary light
In powder film 1, so that the colour temperature for the white light being finally emitted by layered optical diaphragm 2 is no more than 15000K.
Further, the layered optical diaphragm 2 includes the high reflectance film layer 21 and antiradar reflectivity film layer 22 being sequentially stacked；
Usually, the reflectivity of high reflectance film layer 21 is controlled to be more than 2, the reflectivity for controlling antiradar reflectivity film layer 22 is 1.2~1.5,

Under the conditions of it is more few better；To illustrate exemplified by two layers respectively in Fig. 1, but the present invention is not restricted to this；Third, for lamination light
Learn the specific of high reflectance film layer 21 and antiradar reflectivity film layer 22 in diaphragm 2 to stack order and do not make special provision, that is to say, that can
It is disposed adjacent with high reflectance film layer 21 and fluorescent powder film 1, can also antiradar reflectivity film layer 22 and fluorescent powder film 1 is adjacent sets
Put, but this is not represented can arbitrarily arrange two when multilayer high reflectance film layer 21 and multilayer antiradar reflectivity film layer 22 be present
Person.
In the backlight module of the present invention, it is clear that in order to be mixed with the blue light that blue-ray LED is sent to form white light,
The complementary colored particle 11 being arranged in fluorescent powder film 1 with Yellow light-emitting low temperature or can glow and green glow；Complementary color tablets in the present embodiment
Son 11 preferably includes feux rouges particle and green glow particle, and feux rouges particle is preferably red light quantum point, and green glow particle is preferably green
Light quanta point.
Thus, in the backlight module of the present embodiment, because the setting of fluorescent powder film component can be carried out repeatedly to blue light
Utilize, improve blue light launching efficiency, therefore the dosage of red light quantum point and green light quantum point can be reduced, reduce and be fabricated to
This.Meanwhile the backlight module that the present embodiment provides not only effectively increases viewing visual angle, improves the visual experience of beholder,
The conversion efficiency of system is also greatly improved, reduces job number, so as to reduce further cost.The fluorescent powder film component
Improve LCD, it is particularly possible to avoid the drawbacks of big visual angle viewings of wide viewing angle LCD (i.e. VALCD) are bad in the prior art, lift color
Domain, lift image quality.
Based on the structure of above-mentioned fluorescent powder film component, the preparation method of the fluorescent powder film component of the present embodiment include with
Lower step：
Step S1, one fluorescent powder film 1 is provided, in fluorescent powder film 1 filled with can send formed with blue light it is white
