Abstract

This Small Business Technology Transfer Phase I project shall develop and model phase separating materials for passively-driven graphical displays, which are needed for smart cards that can display graphic images. Nearly all consumer credit cards used today have no functional display. Since the numbers and security codes on the cards cannot be changed, fraudulent use is estimated to be as high as $40 per account annually. The current market for smart card displays is limited to segmented designs, but there is a growing need for smart cards to display graphical content such as characters, symbols, and images. The proposed work will: (1) enable encapsulated material formulations for graphic display use; (2) model the photopolymerization/phase separation process to predict conversion efficiency and residual contamination in the cholesteric liquid crystal (ChLC) at the University of Akron (UA); (3) test model predictions with characterized displays at both locations; (4) use formulations to make and integrate a 128x32 pixel graphic display in a smart card; and (5) jointly with a card manufacturer, integrate the display in a card and test to ensure that ISO specifications and customer requirements are met.
