Abstract

We came up with a practical setup and simulation for building a glassless autostereoscopic 3D display system based on the concept of “eye space” with a dynamic shutter parallax barrier. “Eye space” is designed based on geometrical optics to get a multi-view as much as possible by adjusting the width of the slit and parallax barrier dynamically. The dynamic parallax barrier is placed in front of the display screen to form the shutter screen. The addressable drive circuit controls the switches of the pupil windows on the shutter screen. The two signals are synchronous with the drive circuit and the frame frequency scanning of the display screen. The shutter parallax barrier makes it possible that all right and left eyes in the “eye space” see their own views simultaneously. The numerical simulation and experimental verification with simplified 1D pupil windows and a field-programmable-gate-array-based driving circuit unit, which have good practical value, are described in this paper.
