<p>The panel (10) has an array of cells each actuable to change from an opaque to a light transmissive state, with arrangements actuating the cells to effect a raster-scan of the panel. In this way, a "flying hole" sweeps the face of the panel. As described, the cells are defined by row and column electrodes (22a - 22m, 20a - 20n) on opposite sides of a liquid crystal layer. The panel may be used in a display device, a light source modulated by a video signal being viewed through the panel, or as a pickup device in which light from an image scanned by the panel falls on a photosensor to generate a video signal. </p> |
