De Montfort University (DMU) has developed an autostereoscopic display that is targeted specifically at television applications. The display is capable of supplying 3D images to multiple viewers who are not required to wear special glasses, and who are able to move freely over a room-sized area. It operates by producing regions (exit pupils) in the viewing field where either a left or a right image is seen. The positions of the exit pupils are steered to the viewers’ eyes by the use of head tracking. The DMU display consists of an LCD whose conventional backlight is replaced by a steerable optical configuration that is capable of producing several pairs of exit pupils. Left and right images are produced on alternate pixel rows of a single UXGA LCD. This spatial image multiplexing is achieved by the use of a lenticular sheet located between the steering optics and the LCD. The steering optics can produce exit pupils over a large area, but without the aberration and coloration effects associated with other methods. This is achieved using arrays of coaxial lenses in conjunction with high-density white LED array sources.
