The E Ink persistency contest, your chance to win a new e-reader – from e-ink-info.com
Last week we posted about E Ink display persistency – and the fact that those displays can actually retain an image for years. Now it’s your turn to try and think of applications for this feature. Besides making some nice B&W photo frames – what cool things can be done with a display that can stay persistent for such long times without a power source? For example gadgets that only need to change the display once a day…

Just post your idea as a comment below, and be sure to leave your e-mail (you can also send the e-mail in private, of course). We’ll choose the two best ideas, and award them with new e-readers (either a Kindle paperwhite or a Nook Simple Touch with Glowlight). This contest is open for everyone. E Ink, who were kind enough to give away the two e-readers, will ship them worldwide. We’ll choose the new winners on December 11th.
Please post all suggestions directly to e-ink-info.com. Suggestions posted below will not be entered into the contest.
I am not sure how it the years-long persistency can be used.. but
An e-Ink panel with a touch layer can double up as a second screen for the many android phones out there supporting MHL standards. (We know that USB is a one way communication port.) The micro usb port on the Android Phone can output the display to an e-Ink display with a touch layer. The screen would retain the image, until it changes. Any user interaction via touch would be read via the same micro-usb port, after which the display changes. Of course, there could be an app running in the background which could control the secondary display. Even the E-Ink screen could be made as a primary display, with the back-lit LCD as the secondary, only to consume multimedia… Hope I could convey.
