Switchable lenticular lens array and 2d / multiview switchable lenticular display

Abstract

The invention provides a switchable lenticular lens array comprising: a first material layer having a fixed refractive index; a second material layer having an electrically controlled refractive index; and electrodes configured to deliver a voltage or a current to switch the state of switchable lenticular lenses of the switchable lenticular lens array, wherein the electrodes include an upper electrode and a lower electrode; wherein the second material layer is disposed in an electric field in a first direction when a first electrical potential is applied between the electrodes such that the electrically controlled refractive index of the second material layer is switched to a refractive index that matches the fixed refractive index. The present disclosure also provides a 2D / multiview switchable lenticular display.
