Middle excited by quanta point material QD, and produce the second coloured light CL_2.It is to say, each light source die
The first coloured light CL_1 and the second coloured light CL_2 of another part can mixedly be issued by group 110,
The light-emitting uniformity making backlight module 100 entirety preferably and is difficult to colour cast.Additionally, due to need not be by
Thin film containing quanta point material QD is arranged in the pH effect of backlight module 100 in the form of integral
In part 120, therefore the usage amount of quanta point material QD can be saved, and e.g. saves containing quantum
The usage amount of the film size 50% to 60% of some material QD, and make light source module 110 and the back of the body
The cost of light module 100 reduces.Meanwhile, general quanta point material QD contains heavy metal element cadmium
(cadmium,Cd).For example, when using the quanta point material QD with cadmium selenide, quantum
Point material QD i.e. contains heavy metal element cadmium.Therefore, the usage amount of saving quanta point material QD is same
Time, the usage amount of element cadmium also and then reduces, and can obtain preferably environmental benefit.In addition,
Owing to quanta point material QD is not directly packaged in luminescence unit 112, therefore quanta point material QD
It is difficult to damage because of the high temperature by luminescence unit 112 so that quanta point material QD can possess relatively
Long service life.

Outward, covering part and can distinctly be arranged on a light source module doped with quanta point material.Meanwhile, by
Not being directly packaged in luminescence unit in quanta point material, therefore quanta point material usage amount is saved
Save, and quanta point material is difficult to damage because being heated, and make light source module and backlight module cost
Relatively low and service life is long.
The foregoing is only preferred embodiment of the present utility model, it is impossible to limit this utility model with this real
The scope executed, all according to this utility model claim and utility model description made simple etc.
Effect change and amendment, the most still belong in the range of this utility model patent contains.The most of the present utility model
Any embodiment or claim are not necessary to reach the whole purposes disclosed by this utility model or advantage or spy
Point.Additionally, summary part and title are intended merely to assist patent document retrieval to be used, not it is used for limiting
Make interest field of the present utility model.Additionally, " first " that this specification or claim are mentioned, "
Two " etc. term is only in order to the different embodiment of title or difference naming element (element) or scope, and also
Non-being used for limits the upper limit in number of elements or lower limit.
