Crosstalk-free integral imaging display with wide viewing angle using periodic black mask

Two of the main limitations of integral imaging are the crosstalk and the narrow viewing angle. In this paper, a crosstalk free integral imaging display with wide viewing angle is proposed. A layer of transparent high refractive index packing medium is padded onto a display panel to enhance the viewing angle, and then a periodic black mask is coated on the top surface of the medium layer to avoid the crosstalk and image flipping. The proposed integral imaging display can provide us with crosstalk free 3D images within a wide viewing angle. Experiments are carried out and good results finally verify the feasibility of the proposed method.
