Multi-View 2D/3D Switchable Display with Cylindrical Liquid Crystal Lens Array

open access: yesCrystals, 2021
We propose a multi-view 2D/3D switchable display by using cylindrical liquid crystal (LC) lens array with a low operating voltage and fast response time. The cylindrical LC lens array is composed of three parts: the LC layer, a top-plane indium tin oxide
