Taiwan's Industrial Technology Research Institute (ITRI) showed off a few flexible e-paper prototypes. One of these is a color e-reader touchscreen display. It's a Ch-LCD (cholesteric liquid crystal display), thin and light and consumes very little power, and should be cheap to make.
ITRI also showed a sheet of Ch-LCD e-paper and an e-paper writing device that looks like a large scanner and writes patterns onto the Ch-LCD e-paper. The e-paper screen is embedded in the middle of a sheet of thin card, and is reusable so the images on the screen can be changed. The writing device took about 40 seconds to put an image onto the 3.5-inch by 4.5-inch e-paper screen during a demonstration. The researchers envision many uses for the e-paper, including in posters, documents, maps, and greeting cards, which were at the display, and other products.
ITRI is also showing new technology as part of the joint-effort with Corning. Organic thin-film-transistors (OTFT) which are thin, flexible and low cost, and might be a possible screen technology for e-paper.
ITRI is also showing new flexible color OLED displays.
