BACKLIGHT MODULE AND LIGHT GUIDE PLATE THEREOF

The present invention discloses a backlight module and a light guide plate thereof. The light guide plate has a side incident surface, a light-emitting surface adjacent to the side incident surface, and a micro-structure array adjacent to the side incident surface. The side incident surface receives...

description The present invention discloses a backlight module and a light guide plate thereof. The light guide plate has a side incident surface, a light-emitting surface adjacent to the side incident surface, and a micro-structure array adjacent to the side incident surface. The side incident surface receives incident lights from a light source. The micro-structure array has a plurality of elongated prisms, and an end of each of the prisms is oriented to the side incident surface, so that an extension direction of each prism is parallel to or nearly parallel to a normal line of a light-emitting surface of the light source. The light guide plate can increase light transmission distance to provide uniform brightness. The structures of the prisms are maintained in a uniform arrangement, so that a prism mold need not be re-designed to satisfy requirements of panels with different sizes.
