Laser, remaining area are used for transmission laser, that is, the part in the laser being radiated on the spectrophotometric unit is reflected, rest part
It is transmitted on next adjacent spectrophotometric unit, adjacent spectrophotometric unit by irradiation a part of laser reflection on it, remains again
The laser transmission of remaining part point, and so on, to the last a spectrophotometric unit all reflects remaining laser, so far completes
The more uniform distribution of light.It is sharp that laser backlight in compared to the prior art needs multiple laser cells to emit simultaneously
Light only needs a laser cell to emit laser in the embodiment of the present invention, thus simple in structure, and cost is relatively low.
Further, with reference to figure 1 and Fig. 2, N number of spectrophotometric unit is spacedly distributed along the exit direction of laser；Each light splitting
Unit is reflection and transmission film 11；Reflection and transmission film 11 includes reflector space 111 and regional transmission 112；Each reflection and transmission film
The 1/N of the laser total amount of 11 11 equal reflection laser unit of reflector space transmitting.Wherein, the laser meeting of reflector space 111 is injected
It is reflected, injecting the laser of regional transmission 112 can be transmitted.
In practical applications, with reference to figure 1, reflection and transmission film 11 can be made as to circle, reflector space 111 and transmission area
Domain 112 is sector region.When including N number of reflection and transmission film 11, just each circular reflection and transmission film 11 is divided into N number of
The sector region of homalographic, reflector space 111 only account for one of sector region, remaining sector region is regional transmission
112.Along Laser emission direction, the projection of the reflector space 111 of N number of reflection and transmission film 11 on any one reflection and transmission film 11
It is overlapped with the reflection and transmission film 11, the reflector space 11 of each reflection and transmission film 11 can be realized and reflect using this structure and swash
The purpose of the 1/N of the laser total amount of light unit transmitting.
Laser cell in the embodiment of the present invention can be accomplished in several ways for providing white light.It is exemplary, first
It is RGB laser light mixing devices that laser cell, which can be directly arranged, in kind mode, which may be implemented tri- colors of RGB
The mixing of laser is to form white light；The second way can emit blue laser to excite flourescent sheet using blue laser device 12
Fluorescent powder in 13 is to form white light.It is not limited in the embodiment of the present invention.
For the second way, specifically, laser cell includes blue laser device 12 and at least one flourescent sheet 13, it is glimmering
It is any one in yellow fluorescent powder, yellowish red color fluorescent powder or red green fluorescent powder to have fluorescent powder, the fluorescent powder in mating plate 13
Kind；Blue laser device 12 is for emitting blue laser；The blue laser can excite the fluorescent powder in flourescent sheet 13 white to be formed
Color backlight.Wherein, blue laser device 12 can be blue laser diode, or blue laser, the present invention are implemented
