<p>A stacked, passive display apparatus including first and second layers of chiral nematic liquid crystal material includes substrates (30a, 28a, 28b, 30b) binding the first layer (34a) of liquid crystal material and the second layer (34b) of liquid crystal material so as to prevent communication between the first and second layers of liquid crystal material. Electrical conductors (44) interconnect the first row electrodes (37) and the second row electrodes (38) and electrical conductors (43) interconnect the first column electrodes (39) and the second column electrodes (40). Row driver electronics (202) are electrically coupled to one of the first row electrodes (37) and the second row electrodes (38) for applying voltage to both the first row electrodes (37) and the second row electrodes (38). Column driver electronics (204) are electrically coupled to one of the first column electrodes (39) and the second column electrodes (40) for applying voltage to both the first column electrodes (39) and the second column electrodes.</p> |
