New Type of e-Paper Can Be Used Up To 260 Times

joaommp writes "Taiwanese scientists developed a new type of film that can be printed on a thermal printer and erased up to 260 times. The boffins at the Industrial Technology Research Institute claim it as an ideal replacement for paper signs and posters. It does not require patterned electrodes. It is based on a plastic film covered with cholestric liquid crystal, a type of liquid crystal structured similarly to cholesterol molecules and can be erased by simply plugging it to a power source and an A4 sheet costs only US $2. It is expected to be available to consumers within the next two years."
