DTI has demonstrated a backlight for LCDs that creates autostereoscopic 3D with no sacrifice in quality to conventional 2D images. The new backlight is comparable in size and cost to standard 2D backlights and can be manufactured using similar processes. Prototypes have been used in amusement games, LCD desk top monitors, and PC Notebooks.An acrylic light guide accepts light from a miniature fluorescent lamp. Linear structures on one side of the guide reflect light traveling through it toward the LCD. A lenticular lens images the light from the structures

Dimension Technologies Inc. (DTI) has experimentally demonstrated an optical system that produces autostereoscopic images and also allows very high brightness and power efficiency to be achieved using off the shelf color LCDs. This capability is important in applications such as cockpit displays or mobile, portable, or laptop systems where brightness must be maximized but power conserved as much as possible.The effects are achieved through the creation of light line illumination, by means of which autostereoscopic images are produced, and by simultaneously concentrating the light emitted by the display toward the area the viewer's head is. By turning different illumination sources on and off, it is possible to aim both the concentration area and the 3D viewing area at the observer's head as the observer moves. A variation on the system allows two or more persons to be tracked independently. Cross talk (ghosting) can be reduced to the point of imperceptibility can be achieved.

Dimension Technologies has developed a black and white 640 X 480 pixel flat panel autostereoscopic computer monitor that is compatible with the IBM PC family of computers and most compatibles. The monitor employs a liquid crystal display as the image generating element. The LCD is used in combination with a patented illumination system to produce vivid stereoscopic Images that can be seen by several observers from several locations in front of the screen. This paper describes the monitor and how It works, the advantages of DTI's autostereoscopic technology, and the results achieved with the monitor as a display device for computer generated images and still television images.
