Method of manufacturing light guide panel with pattern accuracy










Image Number 5 for United States Patent #8128800.

A method of manufacturing a mold for producing a light guide panel and a method of manufacturing the light guide panel using the mold are presented. The mold is made by manufacturing a pattern master on which a fine pattern is formed. A side mold for forming a light-receiving surface of a light guide panel is immersed in an electrolyte containing metal ions, along with the pattern master. A voltage is applied to the electrolyte and the side mold such that the fine pattern on the pattern master is transferred to the side mold with the metal ions in the electrolyte, forming a prism pattern forming portion on the side mold. The prism pattern is formed on a light-receiving portion of the light guide panel using the side mold thus prepared. The shape accuracy and surface accuracy of the prism pattern are improved by using the presented method.
