Photoalignment of Liquid Crystalline Materials
Atterwill, Chris K. / Kozenkov, Vladimir M. / Kwok, Hoi-Sing
Photoalignment possesses significant advantages in comparison with the usual 'rubbing' treatment of the substrates of liquid crystal display (LCD) cells as it is a non-contact method with a high resolution. A new technique recently pioneered by the authors of this book, namely the photo-induced diffusion reorientation of azodyes, does not involve any photochemical or structural transformations of the molecules. This results in photoaligning fi...
