Abstract

This paper proposes a new display device for switching between 3D and 2D images. A concave lens array is formed on the surface of a first panel, while a convex lens array is formed on the surface of a second panel. An image-plane of display, the first panel and the second panel are arranged in this order, and the concave lens and the convex lens face each other. When the two panels are brought into contact with each other, they show 2D images equivalent to that of one transparent plate. But when the separation interval between the panels is optimum, we see 3D images similar to that caused by lenticular lenses. This display is applied to a 3D and 2D switchable mobile display.
