Autostereoscopic 3D pictures on optically rewritable electronic paper

In this article, we disclose a method to fabricate the three-dimensional (3D) image on an optically rewritable (ORW) electronic paper (e-paper) by deploying the lenticular lenses array on the top of the ORW e-paper. Unlike other autostereoscopic 3D liquid crystal displays, our autostereoscopic 3D ORW e-paper is actually a green technology, which is without electrode and voltage. No electricity is needed to maintain the 3D image on the ORW e-paper. We can easily change a 3D image by erasing and rewriting with photoalignment technology.
