The purpose of this work is to develop an X-Y addressed electrophoretic image display. Redeposit of indium oxide onto the walls of the potential wells formed by ion-beam milling has delayed delivery of Phase I displays suitable for evaluation by ISI. Methods for removing this redeposit were only partially successful, and means of preventing it are being sought. Several Phase I displays were successfully demonstrated within Philips one was fabricated using the photopolymer technology being developed for Phase II. This and other devices using the photopolymer dielectric showed much less sticking of pigment, and therefore improved contrast, than that of the ion-beam-milled Mylar devices. Other photopolymers are being evaluated and perimeter sealing methods compatible with photopolymer construction are under investigation.
