  3. 3. Prologue – The Introduction <ul><li>Think of a technology that could provide you with a large display screen which could be rolled, folded & manipulated to fit into a tiny space when not being used. </li></ul><ul><li>Think of a display screen which uses less battery power than the backlight of your cell phone. </li></ul><ul><li>Think of a revolution which will replace CRT, LCD & TFT in few years and change the way we view our daily digital gizmos. </li></ul><ul><li>This is e-Paper – Screen of the future. </li></ul>
  4. 4. The Legacy – 1 st step towards e-Paper <ul><li>Back in 1975, Nicholas Sheridan stared his research on ePaper. </li></ul><ul><li>The solution he came up with was to use tiny electrically charged spheres, enclosed in the oil filled cavities of a thin layer of a transparent elastomer. </li></ul><ul><li> Each 100-micron dipole sphere is colored half white & half black. </li></ul><ul><li> When an electric charge is passed over certain areas of the film, </li></ul><ul><li> the spheres in those areas rotate accordingly. </li></ul><ul><li>A chip can control the charges at different areas to produce the desired controlled output sketch on the transparent top screen. </li></ul>E InkLegacy.jpg
  5. 5. How does it work now? <ul><li>Now, ePaper uses microcapsules that contain granules of +vely charged white pigments & -vely charged black pigments. These capsules are suspended in a clear fluid between thin layers of a plastic material laminated on a layer of micro-circuitry & electrodes. </li></ul><ul><li> </li></ul><ul><li> </li></ul><ul><li> To draw a display, the electrodes are charged either +ve or –ve as per image requirement. If an electrode is charged +ve, the +ve white pigment granules in the capsule directly above it are pushed to the top, forming a white pixel. </li></ul><ul><li>The two electrodes under each microcapsule can be polarized differently as well, thus forming a half white & half black pixel. Thus ePaper achieves higher resolution & shades of grey. </li></ul><ul><li>All these circuitry forms a screen with a calculable resolution which can be controlled by a display driver or graphics chip. </li></ul>E InkePaper.jpg
  6. 6. Uses at present <ul><li>e-Paper displays might have an important part to play in everyday life. Let’s take a look at a few ways e-Paper displays have started to revolutionise a few areas of everyday life. </li></ul><ul><li>Expect to see a lot more of these examples in the near future. </li></ul>EXAMPLES ->
  7. 7. Philips READIUS <ul><li>This gadget is a mobile e-book reader featuring a rollable e-paper display capable of four monochrome shades. </li></ul><ul><li>Screen resolution is 320x240 with a contrast ratio of 10:1. </li></ul><ul><li>When closed, it measures a mere 100x60x20 mm, making it extremely pocket-able. </li></ul><ul><li>It is able to receive news & updates easily through Wi-Fi, Bluetooth, or even cellular n/w. </li></ul>E InkPhilips Readius.jpg
  8. 8. Seiko Timestrap <ul><li>This watch looks like a stylish wristband and is incredibly slim & sleek. </li></ul><ul><li>The display is made up entirely of e-Paper display & offers a high-contrast screen. </li></ul><ul><li>It has virtually no power consumption when compared to other display technologies. </li></ul><ul><li>Since the display is flexible, designers are able to achieve cool designs involving curves, that were not possible earlier. </li></ul>E InkSeiko.jpg
  9. 9. POP Promotion <ul><li>A Point-Of-Purchase (POP) Promotion is an advertising gimmick undertaken in stores to attract customers to a particular product. </li></ul><ul><li>Microsoft used e-Paper display to attractively animate the packaging of the new Xbox game Jade Empire . </li></ul><ul><li>We can preview actual screenshots of the games, and read the review of the game before buying them. </li></ul>E InkJade Empire.gif
  10. 10. Prototypes – Gizmos of Future <ul><li>Let’s take a look at some products that are currently in development and which should reach the markets within the next few years. </li></ul><ul><li>We’ll look at some of the possible implementations of e-Paper display. </li></ul>
  11. 11. Computer / TV Monitor <ul><li>The most promising implementation of e-Paper is the ultra slim monitors for TV, PCs, Laptops etc. </li></ul><ul><li>e-Paper monitors would be paper thin and easily mountable on walls, thus saving desk-space. </li></ul><ul><li>They could be folded & packed when not in use. Thus it would also provide ultra portability. </li></ul><ul><li>These monitors would provide high contrast display, making them viewable even under direct sunlight . </li></ul><ul><li>It will consume just a fraction of power as compared to LCD or CRT displays. </li></ul>
  12. 12. Electronic Newspaper <ul><li>One of the most obvious implementation of e-Paper display is to replace newspaper. </li></ul><ul><li>The e-Newspaper would be foldable, half the size of conventional news paper & won’t be 40 pages thick. </li></ul><ul><li>This paper can be connected via Wi-Fi to news servers. Essentially, one would need the single paper to read all the news from all favorite news sources. </li></ul><ul><li>This newspaper would enable the user to access the news as it happens. </li></ul><ul><li>It’ll also enable reader to sort the news according to his taste. That is, one can program the paper to display specific genres of news from specific sources. </li></ul>
  13. 13. Animated Hoardings <ul><li>Another exciting use of e-Paper would be animated hoardings. </li></ul><ul><li>Adds of these hoardings can be changed very rapidly & on the fly. </li></ul><ul><li>Add space can be sold as per the time of the day. </li></ul><ul><li>It’ll facilitate animated advertisement that are just as visible in the day as in the night; current neon signs are useless in daytime. </li></ul><ul><li>There are also huge power savings that these will offer over neon signs. </li></ul>
  14. 14. Drawbacks vs Advantages <ul><li>Monochrome display </li></ul><ul><li>Low refresh rate </li></ul><ul><li>Low resolution display till date </li></ul><ul><li>Ultra slim & lightweight display screen </li></ul><ul><li>Foldable & extremely portable </li></ul><ul><li>High contrast ratio, viewable under sunlight </li></ul><ul><li>Low power consumption </li></ul><ul><li>Low cost, profitable, attractive products </li></ul>
  15. 15. Conclusion – The return of paper <ul><li>When e-Paper displays are successfully made color enabled, perhaps all of us will be able to enjoy gadgets that don’t keep running out of battery life and have screens we can actually read easily even under direct sunlight. </li></ul><ul><li>Since every development in the past few years has revolved around mobility & ease of information flow, e-Paper seems to fit right into the mould for the future. </li></ul><ul><li>Add to that, thanks to their reduced cost & better life, we’re set to see the return of the paper era, albeit in the new form of e-Paper. </li></ul>
