LIGHT GUIDE PLATE HAVING RIBS AND BACKLIGHT MODULE HAVING SAME

摘要

A light guide plate includes a bottom surface, a light-emitting surface, a light incident surface, a first side surface, a second side surface, and a number of ribs protruding from the bottom surface away from light-emitting surface. The ribs extend substantially parallelly from the first side surface to the second side surface and are continuously arranged without gaps in between. Each rib includes a first surface, a second surface, and a third surface. The first surface and the second surface extend from the bottom surface. The second surface is further from the light incident surface than is the first surface. A first included angle between the first surface and the bottom surface is an acute angle, and the third surface connects the first surface to the second surface.

主权项

1. A light guide plate comprising:
a bottom surface; a light-emitting surface opposite to the bottom surface; a light incident surface, a first side surface, and a second side surface connecting the bottom surface to the light-emitting surface respectively; and a plurality of ribs protruding from the bottom surface away from the light-emitting surface, the ribs being prisms, extending from the first side surface to the second side surface, and being parallel to each other, each rib comprising a first surface, a second surface and a third surface, the first surface and the second surface respectively extending from the bottom surface, the second surface being away from the light incident surface relative to the first surface, a first included angle between the first surface and the bottom surface being an acute angle, the third surface connecting the first surface to the second surface.
