A full parallax multi-focus 3D display system using LEDs

A full parallax MF(multi-focus) 3D display system is developed and monocular accommodation and omnidirectional focus effect are tested. Four parallax images generate omnidirectional focus effect. The MF means the ability of monocular depth cue at various depth levels. We developed a 3D display system for only one eye, which can satisfy the full parallax accommodation to displayed virtual objects within defined depths via embodiment of MF function. Therefore this proposed 3D display system has a possibility of solving eye fatigue problem that comes from the mismatch between the accommodation of each eye and the convergence of two eyes. The monocular accommodation is tested and a proof of the satisfaction of the full parallax accommodation is given as a result of the proposed full parallax MF 3D display system. We could achieve a result that omnidirectgional focus adjustment is possible via only four parallax images.
