Read Abstract +

We have proposed a wide-viewing area autostereoscopic displays using eye tracking system in order to expand the viewing zone of glasses-free stereoscopic displays using a parallax barrier. It was possible to keep the stereoscopic vision by arranging parallax images at geometrically optimal positions based on the viewer's position detected by eye tracking even if the viewer moved. However, due to the expansion of the viewing zone, when the viewer observes a display at a large angle for the normal direction of the display, the influence of the refraction of light rays by the material between the parallax barrier and the display becomes large and the optimum position to arrange parallax images changes. As a result, the crosstalk occurs and the stereoscopic vision was lost in the areas of large angles. In order to overcome this problem, we propose the image processing method considering the influence of refraction to extremely increase the viewing zone angle. Considering the influence of the refraction, we evaluate the position of the subpixel actually observed by the viewer. Based on the evaluation, we correct the position of the parallax images. To verify the effectiveness of the proposed method, we measured crosstalk at the OVD. When we use the proposed method, the viewing zone angle with a crosstalk rate of 10% or less for the entire display could be expanded to ±30° compared to viewing zone angle ±12.8 without proposed method.
