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

Electrochemical glazing having electrically controllable optical and energy-related properties

A laminated glass pane is described including a) a substrate glass, b) at least one layer structure applied to the substrate glass, c) at least one polymer layer applied to the layer structure, d) a cover glass on the polymer layer, wherein the mean coefficient of thermal expansion of the substrate glass is at most 18&#xd7;10Kgreater than or at most 18&#xd7;10Kless than the mean coefficient of thermal expansion of the cover glass, and in the temperature range from &#x2212;40&#xb0; C. to +90&#xb0; C., the maximum mechanical stress of the laminated glass pane is less than or equal to 7 MPa. Uses of the laminated glass pane are also described.

Laminated glass pane and use thereof

The invention relates to glazing () comprising a first glazing sheet (A,B) forming a substrate on which at least one film of an electrochemical system () is formed, said system having optical and/or energy-related properties that are electrically controllable, a second glazing sheet () forming a counter-substrate, and a third glazing sheet (). 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 () is formed. The substrate is located between the counter-substrate () and the third glazing sheet () and is set back relative to the counter-substrate () and relative to the third glazing sheet () over the entire circumference of the substrate (A,B).

Multilayer film () with electrically switchable optical properties, comprising, arranged sheet-wise in order, at least: &#x2014;a first carrier film (), &#x2014;a first electrically conductive layer (), &#x2014;an active layer (), &#x2014;a second electrically conductive layer () and&#x2014;a second carrier film (), wherein&#x2014;the multilayer film () has at least two circumferential separating lines (), which separate an insulated edge region () from the first electrically conductive layer () and the second electrically conductive layer (), &#x2014;the first carrier film () and the second carrier film () are welded in at least a part of the insulated edge region () to form a sealed region (), and&#x2014;the separating lines () have a width of 10 &#x3bc;m to 500 &#x3bc;m.

Multilayer film with electrically switchable optical properties

The invention relates to an active device having variable energy/light transmission properties () comprising an active system () between a protective substrate () and a protective cover (), selected from an essentially inorganic electrochromic system, a light valve system, a liquid crystal system, a gasochromic system, a thermochromic system, means leakproof to liquid water and/or water vapor, a surround () made from at least one metal based part () on the periphery of the device, the surround being assembled with the cover and with the substrate by assembling means (to) forming at least part of the means leakproof to water vapor.
