Abstract

Multilayered data carriers comprising several liquid crystal layers (302) with each containing a different fluorescent dye as a guest-host mixture with the liquid crystal material. Each liquid crystal layer includes a electrodes (303) and an alignment layer (305). The alignment layer may contain a fluoresent or non-fluorescent dye species. The control of the liquid crystals allows information to be read out of each pixel separately or in the page by page format. Spacers (306) are used to define the thickness of the liquid crystal layers (302). The electrodes are driven by a controller (312) coupled to a power source (313).
