Optical guide plate and method for making its module core

A process for preparing light guiding plate and its mould core includes such steps as forming many microstructures with the V, U, or pyramid shape on the front surface of transparent substrate by non-isodirection etching, forming many nicrostructures with square, bowl, ellipse, or semicide shape on...

Beschreibung
Zusammenfassung:	A process for preparing light guiding plate and its mould core includes such steps as forming many microstructures with the V, U, or pyramid shape on the front surface of transparent substrate by non-isodirection etching, forming many nicrostructures with square, bowl, ellipse, or semicide shape on the back of the said substrate by isodirection etching, testing optical characteristics, electrocasting mould core, and preparing light guide plate.
