ABSTRACT:
A liquid crystal dynamic barcode display apparatus includes a liquid crystal layer having a plurality of elongated barcode display elements positioned in close side-by-side parallel relation formed thereon. The barcode display elements are activated in patterns to form a barcode pattern which can be scanned by a conventional barcode scanner. Spacing between adjacent barcode display elements is less than that which can be detected by the barcode scanner such that multiple adjacent barcode display elements can be activated to form relatively wide bars of the barcode symbology. Preferably, the display apparatus also includes alphanumeric display elements which are simultaneously activated to form human readable symbols corresponding to characters represented by the barcode pattern.
