    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.

    摘要: 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.

    摘要: A uniform reflective light-guide apparatus can accompany an optional edge light source and includes a light-guiding layer, a reflective layer and a light-exiting surface. The light-guiding layer further has a lateral side to define a light-introducing surface for allowing entrance of lights from the edge light source. The reflective layer is to reflect incident lights back to the light-guiding layer. The light-exiting surface perpendicular to the light-introducing surface is to allow at least a portion of the lights in the light-guiding layer to leave the light-guide apparatus. The reflective layer and the light-guiding layer are manufactured integrally by a co-extrusion process so as to avoid possible existence of an air spacing between the reflective layer and the light-guiding layer.

    摘要: A resin composition consists of a resin mixture, a light diffusing agent and a fluorescent-whitening agent. The resin mixture consists of 50˜99.9 wt % of polystyrene (PS) and 0.1˜50 wt % of polycarbonate (PC). The light diffusing agent is 0.1˜20 wt % of the resin mixture. The fluorescent-whitening agent is 0.00001˜0.02 wt % of the resin mixture. Therefore, the present invention has low cost because of PS and also possesses high thermal resistance and high impact resistance because of PC. Resin plates made from the resin composition, such as diffusion plates, have improved thermal and impact resistances.
