METHOD OF MAKING SMART CARDS, SMART CARDS MADE ACCORDING TO THE METHOD, AND AN LCD PARTICULARLY FOR USE IN SUCH SMART CARDS
A method of making a thin flexible smart card having a printed circuit board (PCB) including a liquid crystal display (LCD) thereon, the PCB and LCD being embedded within a laminate of plastic layers, comprising producing an initial laminate by subjecting a plurality of plastic layers to a relatively high temperature and pressure for a relatively long period of time, producing a cavity in one face of the initial laminate, but terminating short of the opposite face, the cavity being configured and dimensioned to accommodate said PCB and LCD thereon, introducing the PCB and LCD into the cavity from one face of the initial laminate with the LCD facing said opposite face thereof, applying one or more further plastic layers over the one face of the initial laminate to cover the PCB in the cavity, and subjecting the initial laminate and the plastic layers to a low temperature, applied to the side of the further plastic layers at a lower pressure and for a shorter period of time than used in producing the initial laminate, to produce the laminate of plastic layers with the PCB and LCD embedded therein.
