Autostereoscopic display with a shifted LC barrier structure for a wide viewing zone

Abstract

In this paper, we propose a shifted ITO electrode structure of a LC barrier for additional sweet spots in the autostereoscopic 3D display. The shifted ITO electrode is consisted of vertically inter-digital ITO electrodes both bottom and top electrodes. They are assembled with horizontally shifted by a half pitch. We can drive each electrode according to the viewer position. It gives an effect of varying the viewing zone. By doing this, we can widen the viewing zone with head tracking technique. It can give a viewer some freedom of viewing position with an image of high quality.
