For 3D displays to be successful, they must be bright enough to compete with 2D displays and not diminish display resolution. To date, stacked-LCD displays have employed parallax barriers, which use pinhole or stripe patterns to provide view-dependent imagery. We show a prototype that adapts the imagery on both layers to multi-view 3D content, increasing brightness while maintaining display resolution. This promises a future of devices with sharp 2D screens and 3D displays with full horizontal and vertical parallax.
