Abstract

We analyze the effect of aperture width of the parallax barrier on the viewing angle of one-dimensional integral imaging (1-DII) display and propose a 1-DII display that consists of a display panel and a variable parallax barrier. When the variable parallax barrier changes its aperture width, the viewing angle and the optical efficiency of the proposed 1-DII display are compared. The viewing angle is increased by decreasing the aperture width of the variable parallax barrier, while the optical efficiency is increased by increasing the aperture width of the variable parallax barrier.

Highlights

Integral imaging (II) display that presents true three-dimensional (3-D) images with full parallax and continuous viewpoints is regarded as a promising 3-D display.[1]
1-DII autostereoscopic display resembles a multiview display, an important difference between the 1-DII display and the multiview autostereoscopic display is defined in terms of the position and the interval of beam condensing points
The 1-DII displays have been implemented by using a parallax barrier or a lenticular lens array

Summary

Introduction

Integral imaging (II) display that presents true three-dimensional (3-D) images with full parallax and continuous viewpoints is regarded as a promising 3-D display.[1]. There is no need to predetermine the observer’s viewpoints in the 1-DII display. The observer’s viewpoints are light ray converging points and are an important design parameter in the multiview autostereoscopic display. The 1-DII displays have been implemented by using a parallax barrier or a lenticular lens array. The 1DII display using a parallax barrier is a practical solution for a low cost and easy-viewable 3-D display. The relationship between the aperture width of the parallax barrier and the viewing angle of the 1-DII display has not been studied. We analyze the effect of aperture width of the parallax barrier on the viewing angle of the 1-DII display. We propose a 1-DII display using a variable parallax barrier. The viewing angle and the optical efficiency can be adjusted by adjusting the aperture width of the variable parallax barrier
