Demonstrates enhanced optical efficiency in light field displays, suggesting improved 3D visualization.
A two-dimensional (2D) single-layer liquid crystal (LC) lens array with concentric ring-shaped multi-electrode structure is proposed for light field three-dimensional (3D) displays. The application of Indium Tin Oxide (ITO) electrodes as conductive lines enables the effective area with high aperture ratio and high optical efficiency, and the ring-shaped multi-electrode structure allows precise modulation of the spatial phase distribution. Integrating the proposed LC lens array on a high resolution mobile display, a light field 3D display with a wide field of view, 20.3°×15.3°, and a high depth of field, 48 mm, is achieved. The 2D single-layer LC lens array shows great potential applications in holographic displays and 2D/3D switchable light field displays.
