Abstract
This disclosure provides a method for manufacturing a large-version light guide sheet using a mask plate. The method includes adopting a mask plate containing a plurality of regions, performing selective polymerization on a photopolymerizable material mixture which is coated on a large-version light guide substrate () by means of the mask plate, and forming a raised or depressed microstructure () on the large-version light guide substrate (), so as to constitute a large-version light guide sheet. The large-version light guide sheet comprises a plurality of units (U, U, U, U). By dividing the large-version light guide sheet, a plurality of discrete unit light guide sheets that are used for an LCD backlight source and an LED lighting assembly are obtained. The method overcomes the limitations of ink jet printing, injection molding, laser etching and other technologies, and improves the production rate of high-performance thinned light guide sheets.
