Anodizing technique for Liquid Crystal Displays

Abstract

Specific self organized nanoscale structures, process of its formation by electrochemical treatment and its application for Liquid Crystal Displays (LCDs) are considered in this paper. Special pillar titania formation technology is proposed to overcome some restriction incidental to porous alumina alignment layers. Both materials allow designing extremely time-, ultraviolet (UV) - and temperature stable alignment layers. A new method based on anodizing in meniscus region at high current densities has been developed for adjustable tilt porous structures formation. Masking and changing of anodizing parameters can be used to control properties and shapes of the structures
