Prerequisites and processing methods for fabricating light guide film light-incident microstructures

Abstract

A pre-processing material and processing method for processing a light guide film light-incident microstructure are disclosed. The pre-processing material consists of a plurality of light guide film substrates and at least one smaller pressure-receiving film stacked alternately, wherein one side of the pressure-receiving film adjacent to the processing side of the light guide film substrate has a recessed gap relative to the processing side. The processing method includes the steps of providing the pre-processing material, fixing the pre-processing material, and forming a light-incident microstructure. The pressure-receiving film separates the upper and lower light guide film substrates of the pre-processing material, so that the upper and lower light guide film substrates do not stick to each other when the pre-processing material is processed into a light guide film light-incident microstructure.
