| abstract |
The invention relates to an active device with variable energy / optical properties (100) comprising an active system (1, 12) between a protective substrate (2) and a protective cover (3), chosen from an essentially inorganic electrochemical system, a an optical valve system, a liquid crystal system, a gaschromic system, a thermochromic system, means for sealing with liquid water and / or vapor, an environment (50) in at least one metal-based part (5a 5b) around the periphery of the device, the surround being assembled to the cover and to the substrate by assembly means (61 'to 64') making at least part of the water vapor sealing means. |
