E Paper Technology Seminar report







Electronic paper(E-paper) is a portable. Reusable storage and display medium that looks like paper but can be repeatedly written on (refreshed) by electronic means, thousands or millions of times. E-paper will be used for applications such as e-books, electronics newspaper, portable signs, & foldable, rollable displays. Information to be displays is downloaded through a connection to a computer or a cell phone,or created with mechanical tools such as an electronic “pencil”. The electronic paper display is reflective & can be easily read in bright sunlight or dimly lit environments while being able to be seen at virtually any angle just like paper. Its black & white ink-on-paper look gives an appearance similar to that of the most widely read material on the planet newspaper. The unique technology results in a compact & lightweight from factor allowing it to be ideal for highly portable applications.

Electronic paper , e-paper or electronic ink display is a display technology designed to mimic the appearance of ordinary ink on paper. Unlike a conventional flat panel display , which uses a backlight to illuminate its pixels , electronic paper reflects light like ordinary paper. It is capable of holding text and images indefinitely without drawing electricity, while allowing the image to be changed later.

To build e-paper, several different technologies exist, some using plastic substrate and electronics so that the display is flexible. E-paper has the potential to be more comfortable to read than conventional display. This is due to the stable image, which does not need to be refreshed constantly, the wider viewing angle, and the fact that it reflects ambient light rather than emitting its own light. An e-paper display can be read in direct sunlight without the image appearing to fade. The contrast ratioin available displays as of 2008 might be described as similar to that of newspaper, though newly-developed implementations are slightly better. There is ongoing competition among manufacturers to provide full-color capability.

Applications include electronic pricing labels in retail shops, and general signage, time tables at bus stations, electronic billboards,the mobile phoneMOTOROLA FONE F3, and e-Readers capable of displaying digital versions of books and e-paper magazines. Electronic paper.
