Method of manufacturing a light guiding panel and an apparatus for the same, and a particle blasting apparatus for manufacturing the light guiding panel

摘要

Disclosed are a method of manufacturing a light guiding panel by means of carving fine engravings on a surface of a transparent substrate by plasting fine particles and an apparatus for the same. A distributed degree of the engravings gradually increases as they become far away from a light source position. The light guiding panel which has been so manufactured does not need a diffusion sheet and has a good brightness uniformity and a good light effectiveness.
