System and method for time-multiplexed autostereoscopic display

摘要

A system and a method for time-multiplexed autostereoscopic display are disclosed, wherein the system includes a projector, an optical relaying device and a slit array. The projector can project a plurality of rays of different directions in different time sequences respectively. The optical relaying device is optically coupled with the projector for relaying the rays. The slit array is optically coupled with the optical relaying device for being illuminated by the rays. The slit array further has a plurality of regions which are illuminated by the rays respectively; and each of the regions has a plurality of slits which are turned on sequentially for a part of the rays to pass therethrough. Therefore, the display system can reduce the light loss of the rays each time when a 3D virtual image is formed.
