  • Publication number: 20230393385
    Abstract: The invention relates to glazing (1) comprising a first glazing sheet (10; 10A, 10B) 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; 10A, 10B).
