Abstract：
 Disclosed is a background light module group which comprises a light conducting board which includes an incidence plane, an outgoing plane connected with the incidence plane and a reflection plane corresponded to the outgoing plane; a light source which includes a light-emitting surface, the light source is set on one side of the incidence plane of the light conducting board and which light-emitting surface is opposite to the incidence plane of the light conducting board; also includes a reflection mirror and a semi-transparent film, wherein the reflection mirror is set on the two sides of the light source and corresponds to the incidence plane, the semi-transparent film is set on the incidence plane that is right opposite to the light source emitting surface for reflecting light beam from the light source emitting surface and making it inject the incidence plane of the light conducting board.
