Wide‐viewing‐angle dual‐view integral imaging display

A wide‐viewing‐angle dual‐view integral imaging display is proposed. A micro‐lens array, a polarizer parallax barrier, and a display panel are aligned in sequence. The display panel is covered with the polarizer parallax barrier. Two types of orthogonal polarizer slits in the polarizer parallax barrier are alternately aligned. Two types of orthogonal polarizer slits polarize the lights from two types of elemental images. The micro‐lens array propagates two types of polarized lights into two primary viewing zones, which coincide at the optimal viewing distance. Different 3D images are, respectively, observed through two types of polarizer glasses. The viewing angle is enhanced and unrelated to the number of elemental images.
