| 20100157026 | Directional Illumination Unit for Autostereoscopic Displays - A directionally controlled illumination unit is disclosed that deflects light from activated illumination elements into visibility regions by a transmissive image reproduction means. The visibility regions are tracked by the eyes of different viewers to other positions in front of the display via a tracking unit and image control. To avoid a strong correlation of one pixel of the image reproduction means to a deflection element (electro-wetting cell) of a deflection means, the directionally controlled illumination unit comprises a two-dimensional illumination means in front of the image reproduction means arranged in a serial manner in the optical path and a deflection means containing at least one field having an arrangement of electro-wetting cells that can be discretely addressed in groups and adjusted with regard to their refractive behavior by the tracking unit and image control. | 06-24-2010 |
