A thin two-dimensional (2D)/(3D) convertible integral imaging display using an edge-lit light guide plate (LGP) is proposed with improved optical efficiency. The proposed system is composed of an ordinary flat backlight, an edge-lit LGP, and a liquid crystal display panel. The edge-lit LGP is an acrylic sheet edge illuminated with light-emitting diodes (LEDs), and there is a diffuser dot array at the bottom. A point light source array for 3D mode is created by the LGP. The light rays from each point light source are modulated by each elemental image to integrate 3D images. In 2D mode, the flat backlight behind the transparent LGP is turned on while edge-lit LEDs are turned off at the meantime. The 2D and the 3D display modes can be simply switched from one to another by turning on different light sources. The explanation of the proposed system is provided and the experimental results are also presented.
