Light-guide apparatus with micro-structure, and backlight module and LCD device having the same

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. 1. A light-guide apparatus with micro-structure , for accompanying an edge light source , comprising:a light-guiding layer, further defining a light-introducing surface for allowing entrance of lights from the edge light source into the light-guiding layer;a reflective layer for reflecting the lights back to the light-guiding layer; anda light-distributing layer, to sandwich the light-guiding layer in between with the reflective layer, further defining thereof a free surface opposing to the reflective layer as a light-exiting surface, the light-exiting surface being perpendicular to the light-introducing surface for allowing at least a portion of the lights in the light-guiding layer to leave the light-guide apparatus therefrom;the light-guide apparatus characterized on that:the reflective layer, the light-guiding layer and the light-distributing layer are manufactured integrally into a unique piece by a co-extrusion process so as to avoid possible existence of an air ...

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.

Method of calibrating projection lens

A method of calibrating projection lens in a projector is disclosed herein. The method includes setting a coordinate matrix over a visible region of a projector, checking whether a coordinate of a mobile target of the projection lens is located within the visible region, and moving the projection lens to the coordinate of the mobile target when the coordinate of the mobile target is confirmed to be located within the visible region.
