Abstract: The present invention provides a backlight module and a display device. The backlight module includes a back plate; a light-emitting chip formed on the back plate and capable of emitting light rays of a first color; a packaging entity made of a light-transmitting material and configured to package the light-emitting chip onto the back plate; and a phosphor layer formed in the packaging entity and consisting of phosphors doped in the packaging entity. The phosphor layer is configured to convert a part of light rays among the light rays of the first color emitted from the light-emitting chip into light rays of a second color, so as to be mixed with the remaining, unconverted light rays of the first color to form white backlight.

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.
