We developed 12-inch 9-view autostereoscopic partial 2-D/3-D switchable display using liquid crystal gradient index (GRIN) lens. We simulated optically by the stacked refraction-index distribution model and optimized liquid crystal (LC) material and electrode structure. The prototype achieved wide viewing angle and good 3-D image quality with mosaic color filter and vertical lens.

We have developed a new display technology that allows 3-D images to be viewed on a flatbed display without any need for special glasses. Viewing the display from an angle allows the viewer to experience 3-D images that stand out several centimeters from the surface of the display. By employing the integral imaging method, easy-to-view, natural, and lessfatiguing stereoscopic images were observed. The new technology opens up new areas of application for 3-D displays, including arcade games, e-learning, simulations of buildings and landscapes, and even 3-D menus in restaurants.

We have developed a one-dimensional integral imaging autostereoscopic display system consisting of an FPD and a lenticular plate that creates parallel optical beam groups. The reproduced 3-D images are free of distortion and show smooth motion parallax. We describe the methods employed for projection, elemental image alignment, and distortion control.
