In one embdiment the upper optical pattern comprises a plurality of lenticular lens patterns or round prism patterns extending in parallel along a direction from the first side surface of the body to an opposite second side surface, and an interval of first lenticular lens patterns or round prism patterns disposed in a partial luminance area (PLA) of the light guide plate differs from an interval of second lenticular lens patterns or round prism patterns in an area of the light guide plate other than the PLA. In another embodiment the loight incident part includes a side light collection pattern (217) and a side diffusion pattern (219), wherein the side light collection pattern includes a plurality of lenticular lens patterns in a PLA corresponding to a partial display area and wherein the side diffusion pattern includes a plurality of prism patterns in a surrounding area of the PLA. A backlight unit comprising the light guide plate is configured to irratdiate light selectively onto a whole display area of a liquid crystal display panel or onto a partial display area thereof, and futher comprises a light source unit adjacent the light incident part of the light guide plate.

    Abstract: The present invention relates to the field of display techniques, and discloses a light guide plate and a manufacturing method thereof, as well as a backlight module; the light guide plate comprises a light guide plate body and lattice points, wherein the light guide plate body is provided with a light output surface, and a receiving groove for receiving a light source is formed in a surface of the light guide plate body facing away from the light output surface thereof, and a side surface and a bottom surface of the receiving groove form a light input surface. The lattice points are distributed inside the light guide plate body along a plane parallel with the light output surface; the further the lattice points are distanced from the light input surface, the more densely they are distributed. When the above light guide plate is in use, the light source is situated in the receiving groove, and light emitted from the light source is directed into the light guide plate through the side surface and the bottom surface of the receiving groove. Besides, since the further the lattice points are distanced from the light input surface, the more densely they are distributed, the uniformity of light emitted from the light output surface of the light guide plate body can be ensured; in addition, since the lattice points are located inside the light guide plate body, friction is avoided between the lattice points of the light guide plate and the reflecting sheet of the backlight module, which prolongs the life time of the backlight module.
