摘要
A uniform reflective light-guide for accompanying an edge light source to form a backlight module for an LCD display includes a light-guiding layer and a reflective layer. The light-guiding layer further defines a light-introducing surface and a light-exiting surface. The light-introducing surface is to allow lights emitted from the edge light source to enter the light-guiding layer. The light-exiting surface perpendicular to the light-introducing surface is to allow at least a portion of the lights to leave the light-guiding layer. The reflective layer is to reflect the incident lights back to the light-guiding layer. The reflective layer and the light-guiding layer are manufactured integrally into a unique piece by a co-extrusion process so as to avoid possible existence of an air spacing in between. A reflective surface is defined to interface the reflective layer and the light-guiding layer, and a three-dimensional micro-structure is constructed on the reflective surface.
