开发了一种新的双向取向表面。所述取向表面可以用于控制液晶引流(backflow)方向。基于所述新型取向层,成功制造了一种双稳态扭曲向列相LCD,该LCD在U和T态之间转换,不伴随表面锚泊能的破坏(surface anchoring energy breaking)。
A new bilaterally oriented surface has been developed. The orientation surface can be used to control the liquid crystal backflow direction. Based on the novel alignment layer, a bistable twisted nematic LCD has been successfully fabricated that converts between U and T states without the accompanying surface anchoring energy breaking.
