A convertible lenticular liquid crystal (LC) lens architecture is demonstrated using an index-matched planarization layer on a periodically undulated electrode for the homogeneous alignment of an LC. It is found that the in-plane component of the electric field by the undulated electrode plays a primary role in the flat-to-lens effect while the out-of-plane component contributes to the anchoring enhancement of the LC molecules in the surface layer. Our LC device having an index-matched planarization layer on the undulated electrode is capable of achieving the electrical tunability from the flat surface to the lenticular lens suitable for 2D/3D convertible displays.
利用周期性起伏电极上的折射率匹配平坦化层来实现液晶（LC）的均匀取向，展示了一种可转换双凸面液晶透镜结构。研究发现，起伏电极产生的电场平面内分量在平面到透镜的效应中起主要作用，而平面外分量有助于增强表面层中液晶分子的锚定。我们在起伏电极上具有折射率匹配平坦化层的液晶器件能够实现从平面表面到适合二维/三维可转换显示器的双凸面透镜的电可调性。
