Viewer-tracking autostereoscopic flat screen display

摘要

The flat screen (FB) is formed as a unit from a lens raster (R) with extremely small lens pitch of optimum corrected lens structure and a flat display (D). The drive enabling the screen to track the viewer's motion is a multi stage linkage having only turning and sliding pairs. The linkage carries out translatory and rotary motions to maintain constant viewing distance and constant viewing angle when the viewer (B) moves her head.
