  • Most people are familiar with Liquid Crystal Displays (watches, calculators, laptops etc.) and also Plasma displays (the extremely expensive flat screen TVs people envy in department stores). But other technology is being developed for flat screen technology. New advances in LCD technology can make the screens flexible (currently they have to be sandwiched between glass) see http://www.extra.research.philips.com/technologies/paintdisp/ For more details. Light emitting polymer technology also allows flexible displays, but unlike LCD’s does not need a separate backlight. More information on the technology at http://www.cdtltd.co.uk The concept of electronic paper – displays that look and feel like a sheet of paper, with the same definition, is being developed with electronic ink technology. The advantage of this technology is that once an image is set, no more power is required. More information at: http://www.eink.com
