Liquid crystal devices based on photo-alignment and photo-patterning materials, were proposed, including patterned retarders for 3D applications, lenses with electrically tunable focal distance, LC based sensors, switchable q-plates, and optically rewritable E-paper. The photoalignment materials were mostly photosensitive azo-dye layers. The combination of azo-dye layers and liquid crystal polymers were also used for photo patterned phase retarders. The practical applications of new LC elements in 3D displays and other LC technology areas are envisaged.
