    Patent number: 7486341
    Abstract: Systems, methods, apparatus and devices for head mounted stereoscopic 3-D display devices using the tunable focus liquid crystal micro-lens array eye to produce eye accommodation information. A liquid crystal display panel displays stereoscopic images and uses tunable liquid crystal micro-lens array to change the diopter of the display pixels to provide eye accommodation information. The head mounted display device includes a planar display screen, planar tunable liquid crystal micro-lens array and planar black mask. The display device may optionally include a bias lens. In an embodiment, the display device also includes a backlight and a prism sheet for displaying the images on the display screen.
