The uniform inclined perpendicular alignment was successfully obtained by inclined evaporation method and using unpolarized uv light method . it is the first time to observe the tilt direction changes in photo - induced alignment when the exposure uv energy increases 在光定向中,我们用非偏振方法实现了带预倾角的均匀的垂直定向,并首次用控制曝光强度的方法,获得了不同的倾角方向的多区域定向。
