Abstract
Disclosed are an electrically variable transmittance film and a method of manufacturing the same. The electrically variable transmittance film includes a base film, a first transparent electrode layer formed on the base film, a transparent non-conductive layer forming a pattern on the first transparent electrode layer, a variable transmittance layer formed on the transparent non-conductive layer, and including particles movable by an electric field, and a second transparent electrode layer formed on the variable transmittance layer.
Claims16
An electrically variable transmittance film comprising:
- a base film;
- a first transparent electrode layer formed on an entire surface of the base film;
- a transparent non-conductive layer forming a pattern on the first transparent electrode layer;
- a variable transmittance layer formed on the transparent non-conductive layer, and including particles movable by an electric field;
- and
- a second transparent electrode layer formed on the variable transmittance layer,
- wherein the transparent non-conductive layer includes an engraved pattern, and the engraved pattern serves as an electrode.
A method of manufacturing an electrically variable transmittance film, the method comprising:
- forming a first transparent electrode layer on an entire surface of a base film;
- forming a transparent non-conductive layer including partition walls and an engraved pattern, wherein the engraved pattern serves as an electrode;
- forming a variable transmittance layer including one or more particles, on the transparent non-conductive layer;
- and
- forming a second transparent electrode layer on the variable transmittance layer.
