Said module backlight also comprises: the glue frame;
The inclined-plane of said glue frame and said LGP is complementary, and is used to support said LGP.
Said module backlight also comprises:
Backboard;
Said backboard has bending side, and said bending side is used to carry said illuminator.
The angle of the inclined-plane of said LGP and the end face of said LGP is 45 °.
The inclined-plane outer surface of said LGP is provided with the reflectance coating material.
The inner surface or the outer surface on the inclined-plane of said LGP are provided with reflecting material.

The specific embodiment
Through accompanying drawing and specific embodiment the utility model is done further detailed description more below.
As shown in Figure 2, the utility model provides a kind of module backlight, and said module backlight comprises: illuminator 10, LGP 11; Wherein, illuminator 10 is positioned at LGP 11 tops, and the light-emitting area of illuminator 10 is downward, and the light-emitting area of said illuminator 10 is towards LGP 11.
Further, the side near illuminator 10 in the LGP 11 is the inclined-plane, and LGP 11 is end face with illuminator 10 adjacent sides, and a side parallel with said end face is the bottom surface, and the length of side of said end face is greater than the length of side of said bottom surface.
Further, the size of the angle of the end face of the inclined-plane of the said LGP 11 of the common decision of the length of the thickness of LGP 11 and illuminator 10 and LGP 11; Preferably, the equal in length of the thickness of LGP 11 and illuminator 10, the angle of the end face of the inclined-plane of promptly said LGP 11 and said LGP 11 is 45 °.
Further, said module backlight also comprises: glue frame 16; Wherein, said glue frame 16 is complementary with the inclined-plane of said LGP 11, and the inclined-plane of said glue frame 16 is used to support said LGP 11.For example, said glue frame 16 can have an inclined-plane, and the corner dimension of the inclined-plane of said glue frame 16 and glue frame bottom surface equals the corner dimension of end face of inclined-plane and the LGP 11 of said LGP 11, and the angle of the inclined-plane of promptly said glue frame 16 and glue frame bottom surface is 45 °.
Further; Said module backlight also comprises backboard 15; Said backboard 15 has bending side, and said bending side extends out from the side that backboard 15 is provided with illuminator 10, and said bending side is preferably parallel with the bottom surface of backboard 15; Said illuminator 10 is arranged on the bending side of said backboard 15, and therefore said bending side is used to carry said illuminator 10.
