Electrochemical glazing having electrically controllable optical and energy-related properties

Abstract

The invention relates to glazing ( 1 ) comprising a first glazing sheet ( 10; 10 A, 10 B) forming a substrate on which at least one film of an electrochemical system ( 12 ) is formed, said system having optical and/or energy-related properties that are electrically controllable, a second glazing sheet ( 14 ) forming a counter-substrate, and a third glazing sheet ( 18 ). The substrate has characteristics that allow it to be obtained by being cut from a motherboard on which motherboard at least one film of the electrochemical system ( 12 ) is formed. The substrate is located between the counter-substrate ( 14 ) and the third glazing sheet ( 18 ) and is set back relative to the counter-substrate ( 14 ) and relative to the third glazing sheet ( 18 ) over the entire circumference of the substrate ( 10; 10 A, 10 B).
