Key pad, and a method of manufacturing the same, including the light-guiding structure, the light-guiding structure

摘要

The present invention I provide a molded light guide structure including a key pad structure. A light-guiding structure comprises light guiding layer 10, the light-collecting structure 12, and the fine structure area 14. Condensing structure is provided on the light guide layer, collects the light from the light source to the light guide layer, the light guiding layer is to allow the transmitting light. Microstructure region is provided on the light guide layer, the light transmitted by the light guide layer reflected or refracted, thereby emitting light. Condensing structure and the microstructure region, with a light guide layer is formed by a common molding process. .BACKGROUND 4
