Abstract: The present disclosure provides a light conducting device, a backlight module and a display device. The light conducting device cooperates with a light source to form a backlight module. The light conducting device includes at least one light receiving surface. The light receiving surface includes a plurality of annular sub-receiving surfaces configured to cause received light from the light source to be emitted in a single direction.

Abstract: The present invention discloses a light guide plate, a backlight module and a display device. In the light guide plate, a plurality of triangular pyramid dots are provided; two of four surfaces of each of the triangular pyramid dots are light receiving surfaces facing a backlight source, and are reflective mirror surfaces, so that incident light reaching the two light receiving surfaces from the backlight source is converted into emergent light exiting in two different directions, and then the emergent light is emitted out from the upper surface of the light guide plate. In the solution, as the triangular pyramid dots capable of converting incident light from a backlight source into emergent light exiting in two specific directions are provided in a light guide plate, the effect of dual-view backlight can be realized while providing a light guide plate or dual-view backlight module with simpler structure and lower cost.
