Abstract: A backlight module comprises a light source, a light guide plate and at least one transparent light guide structure. Each transparent light guide structure comprises a first surface adjacent to a side of the light guide plate and a second surface far away from the light guide plate, a light emitted by the light source is directed into the first surface of the transparent light guide structure through the light guide plate. Each transparent light guide structure is configured to change a propagation direction of a first light in the light emitted by the light source, so that an emergence angle of the first light emitted from the second surface is smaller than an incidence angle of the first light incident from the first surface. The incidence angle of the first light onto the first surface is less than 90 degrees.

Abstract: A backlight module includes: a frame; a backboard configured to support the frame; a radiator provided in the backboard and connected to an inner wall of the frame; a light source fixed to an inner wall of the radiator; a light guide plate relatively slidably mounted on the radiator and configured to guide light emitted by the light source; and at least one buffer mounted on the radiator and configured so that the radiator is moveable relative to the backboard against an elastic force of the buffer. The backlight module can effectively eliminate the phenomenon in which a shadow of the light source is present in pictures coming from the backlight module since the light guide plate presses against the light source after it is heated to expand. The present invention further provides a display device including the above backlight module.
