ELECTROCHEMICAL WINDOW WITH ELECTRONICALLY CONTROLLED OPTICAL AND / OR ENERGY PROPERTIES

摘要

The invention relates to a glazing unit (1) comprising a first glass-forming sheet (10; 10A, 10B) forming a substrate on which at least one layer of an electrochemical system (12) with optical and / or energetic properties is formed. electrically controllable, a second glass-backed sheet (14) forming a counter-substrate, and a third glazed sheet (18). The substrate has characteristics specific to obtaining by cutting from a parent substrate on which the at least one layer of the electrochemical system (12) is formed. The substrate is located between the counter-substrate (14) and the third glass-backed sheet (18) and recessed with respect to the counter-substrate (14) and the third glass-function sheet (18) around the entire periphery of the substrate. substrate (10; 10A, 10B).
