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.
