Abstract (en)
[origin: WO0077559A1] Electro optical device (29) with variable transmission with and without electric power is provided which constitutes an electro optical cell having a chromogenic component in addition to the electro-optically switchable feature. The chromogenic component can be a photochromic, thermochromic, and/or dichroic material and mixtures of these. The chromogenic component is a coating, film or layer can be on one or more of the transparent substrates (37, 39) of the electro-optical cell or a part of the electro-switchable material (43) in the cell. One of the electro-optic devices can be a liquid crystal cell with one or more dichroic dyes present with the liquid crystal material. In another aspect of the invention, the chromogenic component can be a chromogenic guest material with or within the electro-optic device. The electro optical device with the chromogenic material is suitable for use with automotive transparencies such as privacy glass, shade bands, and passenger partition screens in vehicles; architectural window use such as skylights and other windows; and eyewear.
