Abstract

The invention provides a method for manufacturing an optical composite membrane structure capable of controlling a change in light transmission pattern includes the steps of first providing an optical composite film comprising a polymer liquid crystal dispersion layer, a transparent conductive layer formed on the polymer liquid crystal dispersion layer, Transparent conductive layer; and then, the optical composite film is patterned to remove portions of the transparent conductive layer to form a conductive line pattern and a plurality of leads extending from the conductive line pattern side, and forming a transparent substrate A transparent substrate, a transparent conductive layer and a polymer liquid crystal dispersion layer; and then, at least a sub-surface repair program for the patterned optical composite film; and finally, an electrical contact is formed at the wiring gap.

Description

technical field [0001] The invention relates to a manufacturing method of an optical composite film, in particular to a manufacturing method of an optical composite film structure capable of controlling the change of a light transmission pattern. Background technique [0002] Polymer Dispersed Liquid Crystal (PDLC) is composed of submicron-sized liquid crystal particles (Liquid Crystal droplet) uniformly dispersed in the polymer material, because it "can use an external electric field to operate in the state of light scattering or light Therefore, it can be used on conductive glass, such as encapsulating PDLC in conductive glass, so that the change of the electric field (switch) can be used to make the light-transmitting structure appear transparent or opaque. The conductive glass used to build PDLC is called Smart Windows in the market. [0003] With the upgrading of process technology and materials, the applicability of PDLC has been greatly improved. For example, soft co...
