Developments in Flexible Printed LCDs

Professor Chigrinov says, "The earliest commercialization of photo-aligned bistable LCDs will be in flexible displays for plastic cards. All the problems, like mechanical stabilization and electro-optical appearance, have been solved using photo-aligned azo-dye materials. The closest candidates for the application are π-BTN nematic LCD and ferroelectric LCD. The producers of plastic cards in Hong Kong (e.g., Octopus cards) can be approached for the commercialization of our research results.

After finishing the project, we are also going to approach LCD companies, that produce flexible displays for mobile phones, smart cards, PDAs, electronic books, etc., for which extremely low power operation is required due to the memory effect. Maintaining and updating the deliverables can be made at the Center of Display Research in HKUST."
