Practical Autostereoscopic 3D Display Using a Parallax Barrier With High Image Quality and Wide Viewing Area

We have developed and commercialized a glasses-free 3D display with high image quality and a wide viewing range by solving the problem of screen darkness associated with the parallax barrier method. The eye tracking enabled us to determine which pixel was visible to which eye of the user at any given time, thus increasing the aperture ratio of the barrier. Our method is suitable for commercialization because it has a simple hardware structure and requires little image processing, and we have commercialized it. We have also implemented and commercialized a live 3D system without the need for special glasses using our 3D display.
