METHOD AND EQUIPMENT FOR MANUFACTURING LIGHT GUIDE PLATE

摘要

In a backlight module, a diffusive structure and a prism structure are replaced by a diffusive prism film formed on a substrate and transferred via In-Mold Decoration by Roller (IMR) to a light guide body via injection molding. A reflection film is also transferred to an opposite side of the light guide body via the same way. In such way, optical films may be readily transferred to the light guide body via two-side IMR during the process of injection molding of the light guide body, saving room taken by substrates of the optical components.

主权项

1. A method for manufacturing a light guide plate, comprising following steps:
forming a diffusive prism film on a substrate; attaching the diffusive prism film and the substrate to a first mold and using a first pressing frame for clamping edges of the diffusive prism film; injecting plastics into a mold cavity formed between the first mold and a second mold for forming a light guide body; and separating the light guide body from the first mold and the second mold; wherein when the light guide body is separated from the first mold, the diffusive prism film is transferred onto a first surface of the light guide body such that a light guide plate is formed.
