Zusammenfassung: | The display system uses a coloured or white light source for illuminating a display raster from the rear, each raster element comprising a kerr cell (Z) with two capacitor plates (A,B) providing in electrical field which alters its optical parameters. The display raster is combined with a further optical element comprising a light distribution plate, pref. with a colour filter characteristic, inserted between the light source and the polarisation plate at the rear of the raster plate. The latter pref. defines a rectangular array of cells (2), each filled with the same dielectric material, e.g. nitro-benzol. An analyser plate is positioned in front of the motor plate, the insulating material used for the raster plate used for supporting the capacitor plates (A,B) for each cell (Z). |
