用于集成成像3D显示的模式控制型液晶微透镜阵列
Liquid crystal micro lens array with modal control for integrated imaging 3D display
摘要
Abstract
Liquid crystal lenses have the advantages of compact structure,high integration,and adjustable focal length.This article proposes a method for preparing a liquid crystal micro lens array(LCMLA)with modal control for integrated imaging 3D display.Firstly,the influence of voltage amplitude and frequency on the potential distribution of liquid crystal lenses without and with high resistance layers was analyzed using simulation software COMSOL Multiphysics.Secondly,a transparent high resistance layer of polymer poly(3,4-ethylenedioxythiophene):polystyrene sulfonate(PEDOT∶PSS)and polyvinyl alcohol(PVA)was fabricated on a copper circular hole array electrode.And a comparative experiment was conducted to verify it,the experimental results show that the LCMLA without adding a high resistance layer changes the focal length from ∞ to 25.8 mm and the response speed is 645.7 ms when the voltage changes from 0 to 40 V at a fixed sine wave frequency of 1 kHz.The LCMLA with modal control incorporating a high resistance layer can adjust the lens characteristics by changing either the amplitude or frequency of the driving voltage.When the fixed frequency is 75 kHz,the voltage changes from 0 to 5 V,the focal length changes from ∞ to 19.5 mm,and the response speed is 621.4 ms.When the fixed voltage is 5 V,the frequency changes from 1 kHz to 75 kHz,the focal length changes from ∞ to 19.5 mm,and the response speed is 146.4 ms.Applying the prepared LCMLA with modal control to integrated imaging 3D display can achieve good 3D display effect and fast switching characteristics at low voltage.关键词
