High-resistance liquid-crystal lens array for rotatable 2D/3D autostereoscopic display

Abstract

A 2D/3D switchable and rotatable autostereoscopic display using a high-resistance liquid-crystal (Hi-R LC) lens array is investigated in this paper. Using high-resistance layers in an LC cell, a gradient electric-field distribution can be formed, which can provide a better lens-like shape of the refractive-index distribution. The advantages of the Hi-R LC lens array are its 2D/3D switchability, rotatability (in the horizontal and vertical directions), low driving voltage (similar to 2 volts) and fast response (similar to 0.6 second). In addition, the Hi-R LC lens array requires only a very simple fabrication process. (C) 2014Optical Society of America
