1. SMARTPAPER

2. 2 Topics of Discussion Introduction Structure Working Types Advantages & Disadvantages Applications

3. 3 Smart Paper is a material that looks and feels very much like thick, glossy paper, but is actually a controllable display surface. Invented by Nicholas Sheridon Produced in rolls like conventional paper. But unlike regular paper, it is electrically writeable and erasable.

4. 4 It resembles paper in Stores/displays an image Can be viewed in reflective light Has a wide viewing angle Flexible Relatively inexpensive

5. 5 Structure SmartPaper is actually two sheets of thin mylar plastic sandwiching millions of tiny polymer beads randomly dispersed in an oily medium. Each of the beads are free to rotate within their cavities. Each bead is a hair-like 100 microns in diameter and has a different color on each half. The hemispheres are also charged differently (i.e. positive or negative) so that they exhibit an electrical dipole.

6. 6 Working SmartPaper beads reside in their own cavities within the flexible sheet of material. When voltage is applied to the surface of the sheet, the beads rotate according to the current to present one colored side to the viewer.

7. 7 Working(cont…) Adhesive forces between each bead and cavity wall require an electrical threshold be exceeded before it will rotate. This makes an image electrically "printed" onto the material stable and unchanging until "erased" by another transmission. Electrical signals can be applied to the SmartPaper sheets through fixed surface electrodes or a moving stylus.

8. 8 Working(cont…) Applying electrical fields to the display surface changes the image on SmartPaper. A range of techniques will achieve this result. In the least expensive option, the back plane contains several possible images or preprogrammed text and digit messages. Which image or message is displayed can be controlled by either programming the sign to display a fixed sequence or a dynamically changeable sequence using special software and a wireless network.

10. 10 Types There are two versions of Smart Paper: Normal Advanced.

11. 11 Normal Smart Paper  cannot change very quickly.  Not suitable for video applications.  The resolution is equal to that of a 20th century newspaper.  Has only very crude sensors to detect stylus movements

12. 12 Advanced Smart Paper  Can change so quickly.  Suitable for video application.  Resolution is like that of a modern high quality art book.  Has a fine latticework of sensors to detect the movements

13. 13 Advantages SmartPaper owns several advantages It's reflective, like paper. You don't need a backlight, can view it from an angle and in bright sunlight. The screens can be tiled to create large signs, But unlike many current electronic signs, the messages can easily be changed periodically throughout the day. Unlike a digital display that must be refreshed dozens of times per second, electronic paper is "bi-stable." Therefore consumes less power.

14. 14 Advantages(cont…) Displays made with SmartPaper generally do not degrade over time and will last for years because the images are based on pigments rather than dyes. Signs made with SmartPaper have performed more than 5 million image changes without malfunction or fading. Images displayed on SmartPaper are "held" indefinitely until a new electrical signal is applied.

15. 15 Disadvantages  Resolution for SmartPaper is at least 100 dots per inch.Therefore images on Smartpaper are gray, grainy, and otherwise visually unimpressive.  The company is working on colored displays. But colored pigments, which are needed to display the same charge properties as black and white pigments, remain a technological hurdle.  It will never be as light as paper, Paper is about four mils thick; this will always be 12 or 15 mils thick.

16. 16 Applications  SmartPaper technology is well suited to a wide variety of other market applications, including displays and electronic books/newspapers.  Currently Smartpaper is finding its major use in Syncrosign Message Board which is used for versatile and stylish display.  It combines Smartpaper with SignSync software,Gyricon’s unique messaging software.

17. 17 Applications(cont…)  The primary application for the SyncroSign Message Board is as a dynamic information display. Corporate, educational and hospitality can customize and control these eSigns throughout a large venue, via a wireless network.  SyncroSign Message Board provides accurate content; displaying daily agendas, seminar schedules, and other event information in corporate classrooms, conference rooms or hotel lobbies.

18. 18 Conclusion Smartpaper is capable of projecting simple images with text but in the future color photos and other graphics might become a reality for electronic paper. Smartpaper is very useful for data derived from books.Future libraries may offer scanned images of books for download instead of lending books.It is useful as a replacement for hardcopy. Space colonies with no cellulose to spare for paper will be glad for smartbooks.Smartbooks can store lots of data.

19. 19 Data for smartbooks is produced and published digitally. A future internet may have cores of “library sites” where people can download contents for their smartbook. It makes graphics tablet unneccessary.
