摘要：
A viewing angle enhanced integral imaging display, which consists of a double microlens array, and a display panel is proposed. The double microlens array includes a convex microlens array and a concave microlens array. The display panel is used to display original elemental image array. The convex microlens array, located near the display panel, is used to provide a virtual elemental image array for the concave microlens array. The concave microlens array, located far away from the display panel, is used to display integral images with the virtual elemental image array. Compared with the original elemental image, the pitch for each virtual elemental image is magnified by the corresponding convex microlens. As a result, the viewing angle is expanded. Simulations based on ray-tracing are performed and the results agree well with the theory.
