LAMINATION OF OPTICAL SUBSTRATES

摘要

A method is provided for laminating optical substrates and in particular for manufacturing a thin combiner for an optical display that preserves the flatness of the component parts and ensures an even separation of layers, in particular an optical substrate and a thin cover plate that is to be bonded to the substrate. In the method, spacer particles in a predetermined size range are included within a glue layer at a required density to ensure cover plate flatness and uniform separation during assembly.
