Abstract
A light-guide apparatus for accompanying an edge light source to form a backlight module for an LCD display includes an upper light-distributing layer, a middle light-guiding layer and a lower reflective layer. The light-guiding layer further defines a light-introducing surface for allowing lights emitted from the edge light source to enter the light-guiding layer. The reflective layer reflects the lights back to the light-guiding layer. A light-exiting surface for allowing at least a portion of the lights to leave the light-guiding layer is defined on the top surface of the light-distributing layer and is perpendicular to the light-introducing surface. The light-distributing layer, the light-guiding layer and the reflective layer are manufactured integrally into a unique piece by a co-extrusion process so as to avoid possible existence of air spacing in between. Three-dimensional micro-structures are constructed on a reflective surface interfacing the reflective layer and the light-guiding layer.
