AUTOSTEREOSCOPIC DISPLAY SYSTEM WITH ONE DIMENSIONAL (1D) RETROREFLECTIVE SCREEN |
摘要 |
An autostereoscopic apparatus for providing a 3D image to a viewer at a range of vertical eye locations. The apparatus includes a projection screen with a light receiving surface that is horizontally retroreflective and vertically diffusive. The apparatus includes a projector assembly including at least two projectors arranged side-by-side such that projection lenses of the projectors are horizontally aligned in a row. The apparatus includes a controller selectively operating the projectors to project at least two differing point-of-view images. The projection screen may take a number of useful embodiments to implement the autostereoscopic apparatus. For example, the projection screen may include a bottom layer including a retroreflective film that is retroreflective at least in the horizontal direction such as a brightness enhancement film and a top layer formed of a transparent sheet of lenticular material arranged for vertical diffusing. |
