Abstract

We propose an autostereoscopic 3D display with an increased aperture ratio of the parallax barrier. The problem with high aperture ratio is that subpixels are observed simultaneously by both eyes, resulting in high crosstalk ratio. To overcome this problem, we propose the image processing method that suppresses the crosstalk by displaying crosstalk subpixels in black. Thus, the necessary pixels can be observed as much as possible. Using the prototype system, we confirmed that a wide viewing area with a crosstalk ratio of less than 10% and high quality 2D images with less image quality degradation can be obtained.
