Lenticular lens array based on liquid crystal with a polarization-dependent focusing effect for 2D–3D image applications

Demonstrated herein is a liquid-crystal-(LC)-based lenticular lens array with a polarization-dependent focusing effect, fabricated through a simple imprinting process. The input polarization dependence of the proposed LC lenticular lens array arises mainly from the index matching scheme between the polymer lenticular lens and the LC on it. For the input polarization perpendicular to the LC director, the focal length of the lenticular lens is about 3.1 mm. The focusing and non-focusing properties depending on the input polarization are useful for realizing autostereoscopic 2D/3D convertible displays combined with polarization selection elements.
