To resolve separated viewing zones, a one-dimensional dual-view integral imaging three-dimensional (3D) display based on a polarizer parallax barrier was proposed. The imaging model of the one-dimensional dual-view integral imaging 3D display based on the polarizer parallax barrier was established. The principle of the one-dimensional dual-view integral imaging 3D display was illustrated in detail. The calculation formulas of the width of the viewing zone and the viewing angle were deduced by using geometrical optics. A test equipment of the one-dimensional dual-view integral imaging 3D display was developed. By using left and right polarizer parallax barriers, two different 3D images were viewed from 18° to the left and the right in the same viewing zone.
