This document summarizes a seminar presentation on electronic paper technology. It discusses the history and development of e-paper, including early work by Sheridon at Xerox and challenges with word processing PCs. It outlines the main technologies used in e-paper like Gyricon, electrophoretic, electro-wetting, and electro-fluidic displays. The document explains how e-paper works and its technical aspects. It discusses the impact and applications of e-paper as well as advantages like low power and reusability and disadvantages like low refresh rates. Finally, it covers challenges, the future potential of e-paper, and concludes that it will co-exist with traditional displays.

- 1. Seminar on
- 2. E PAPER TECHNOLOGY Presented by Under The Guidance Of R.S.Gangannavar Prof. M.S.JOLAD VISVESVARAYA TECHNOLOGICAL UNIVERSITY, BELGAUM
- 3. Outline • Introduction • Earlier Overview • Technology Used • How E Paper Works • Technical Aspects • Impact Of E Paper • Applications • Advantages and Disadvantages • Challenges Created By E Paper • The Future Scenario • Conclusion
- 4. Introduction • Traditional Papers •Reliable, Good Readability, High Contrast • E Paper •Reusable, Future paper • Printed words cannot change • No Backlight..!
- 5. Earlier Overview • Nicholus K Sheridon at Xerox research centre • World 1st Office & Word Processing PC by Xerox • Office PC’s Drawbacks • 18 months -> Electronic Capillarity • Unrealistic Work Schedule
- 6. Technology Used Gyricon Electrophoretic E Paper Electro-wetting Electro-fluidic
- 7. How E Paper Works..? • E ink (Front plane) • Electronics to generate Text & Image (Back plane)
- 8. Technical Aspects o Gyricon:- • A plastic within which a liquid is encapsulated •Bichromal front plane •Limitations -> • Low brightness • Low resolution • Lack of colour
- 9. Continued… o Electophoretic front plane:- • This technique is given by making some variation in Gyricon method • 1 um tiny particle & Hyrdocarbon oil with a dark coloured dye • Placed between two parallel conducting sheets with distance of 10 to 100 um • Good in brightness and resolution • Limitations: • Lack of colour • Low refresh rate • Flicker (Due to slow motion of particles from end to end) • Unsuitable for displaying animations and video
- 10. Continued… • Cholesteric Liquid Crystal: • By IBM, HP & Philips • Most of drawbacks are overcome o Electro-wetting:- • Controls shape of water/oil interface on application of voltage else remains flat • Features: • Fast switching • Low voltage • Video support
- 11. Continued… o Electro fluidic:- • Variation of electro-wetting display • Tiny reservoirs employed • Ex. Red Fluids
- 12. Impact Of E Paper • US consumes world’s 1/3 of paper • Cutting of trees • Power consumption while production •How we can contribute..?
- 13. Applications
- 14. Advantages • Paper-like readability • Ultra low power consumption • Thin and Light in weight • Perfect for mobile displays • Twistable • Simple Manufacturing process • Reusable technology • Ease in information downloading • Libraries can be made
- 15. Disadvantages • Low refresh rate Example: Zooming • Ghosting Solution: flash
- 16. Challenges Created By E Paper • Control over illegal downloads of e books • Data for Advertisement • Duties of Teachers and Publishers • Print related activities, Employment and its resistance to change
- 17. Future Scenario • Newspapers • E books • Cylindrical devices
- 18. Conclusion Electronic ink is not intended to diminish or do away with traditional displays. Instead electronic ink will initially co-exist with traditional PAPER and other display technologies. In the long run, electronic ink may have a multibillion-dollar impact on the publishing industry. Ultimately electronic ink will permit almost any surface to become a display, bringing information out of the confines of traditional devices and into the world around us.
