Titel
Printed electroluminescent structures for smart cards
Abstract
We present a new method of fabrication of electroluminescent displays for the integration in plastic cards trough the lamination process. Our approach adapt new printed electronics technology for fabrication of elastic electroluminescent displays with lamination process which is impossible to replace in the production of such cards. Polycarbonate foils used as regular materials for such types of cards are used with specially developed transparent electrodes with double walled carbon nanotubes, dielectric and luminophore ink, deposited with spray coating technique. Silver nanopowder ink is printed as the bottom electrode with an ink-jet printer. In our solution the display can be integrated in cards only by printing and lamination without the use of additional processes or introducing additional electronic components.
