MULTIPLE GLAZING WITH VARIABLE SCATTERING BY LIQUID CRYSTALS AND ITS METHOD OF MANUFACTURE

摘要

A multiple glazing with variable scattering by liquid crystals includes first and second flat float glass sheets sealed on the edge of their internal faces by a sealing joint, in particular made of a given sealing material, in particular essentially organic, first and second electrodes, and a layer of liquid crystals with an average thickness E between 15 and 60 μm inclusive of these values and incorporating spacers. The thickness A of each of the first and second glass sheets is less than or equal to 5.5 mm, and each of the internal faces coated with the first and second electrodes has a dioptric defect score, expressed in millidioptres, of less than 12 E/15 where the thickness E of the liquid crystals is in μm.

1. Multiple glazing with variable scattering by liquid crystals (100) having:
first and second flat float glass sheets (1, 2) sealed on the edge of their internal faces (11, 12) by a sealing joint (7) made of a given sealing material, on the internal faces of the first and second glass sheets, first and second electrodes (3, 4) in the form of transparent electrically conductive layers provided with a power supply, and, on the first and second electrodes, a layer (5) of liquid crystals alternating reversibly between a transparent state and a translucent state by application of an alternating electric field.
