Patent ID: 7728936

Claim:
A method of alignments of liquid crystal employing magnetic thin films, comprising steps of: (a) obtaining a substrate coated with a transparent conductive thin film, wherein said substrate is made of indium-tin oxide (ITO); (b) deposing said substrate into a sputter to be processed through a sputtering to be coated with a transparent magnetic thin film on said transparent conductive thin film with a working gas; and (c) obtaining two of said substrate sputtered with said transparent magnetic thin film, wherein said substrate comprises a first substrate and a second substrate; clipping a liquid crystal layer between said first substrate and said second substrate, wherein a first alignment layer is obtained by said transparent magnetic thin film of said first substrate between said first substrate and said liquid crystal layer and a second alignment layer is obtained by said transparent magnetic thin film of said second substrate between said second substrate and said liquid crystal layer; and surrounding said liquid crystal layer by filling a spacer to assemble a liquid crystal (LC) cell, wherein said LC cell has a liquid crystal alignment obtained through a magnetic field of said first alignment layer and said second alignment layer in said LC cell, wherein said transparent magnetic thin film is made of an inorganic material having an iron oxide composition with a characteristic selected from a group consisting of ferromagnetism and ferrimagnetism.
