In February Journal, UC and İndustry Researchers Predict Future Of Electronic Devices

The just-released February issue of the Journal of the Society for Information Display contains the first-ever critical review of current and future prospects for electronic paper functions – in other words reviewing and critiquing the technologies that will bring us devices like

full-color, high-speed, low-power e-readers;
iPads that can be viewed in bright sunlight, or
e-readers and iPads so flexible that they can be rolled up and put in a pocket.
The University of Cincinnati's Jason Heikenfeld, associate professor of electrical and computer engineering and an internationally recognized researcher in the field of electrofluidics, is the lead author on the paper titled "A Critical Review of the Present and Future Prospects for Electronic Paper." Others contributing to the article are industry researcher Paul Drzaic of Drzaic Consulting Services; research scientist Jong-Souk (John) Yeo of Hewlett-Packard's Imaging and Printing Group; and research scientist Tim Koch, who currently manages Hewlett-Packard's effort to develop flexible electronics.

TOP TEN LIST OF COMING e-DEVICES

Based on this latest article and his ongoing research and development related to e-paper devices, UC's Heikenfeld provides the following top ten list of electronic paper devices that consumers can expect both near term and in the next ten to 20 years.

Heikenfeld is part of an internationally prestigious UC team that specializes in research and development of e-devices.

Coming later this year:

Color e-readers will be out in the consumer market by mid year in 2011. However, cautions Heikenfeld, the color will be muted as compared to what consumers are accustomed to, say, on an iPad. Researchers will continue to work toward next-generation (brighter) color in e-Readers as well as high-speed functionality that will eventually allow for point-and-click web browsing and video on devices like the Kindle.
Already in use but expansive adoption and breakthoughs imminent:

Electronic shelf labels in grocery stores. Currently, it takes an employee the whole day to label the shelves in a grocery store. Imagine the cost savings if all such labels could be updated within seconds – allowing for, say, specials for one type of consumer who shops at 10 a.m. and updated specials for other shoppers stopping in at 5:30 p.m. Such electronic shelf labels are already in use in Europe and the West Coast and in limited, experimental use in other locales. The breakthrough for use of such electronic labels came when they could be implemented as low-power devices. Explained Heikenfeld, "The electronic labels basically only consume significant power when they are changed. When it's a set, static message and price, the e-shelf label is consuming such minimal power – thanks to reflective display technology – that it's highly economical and effective." The current e-shelf labels are monochrome, and researchers will keep busy to create high-color labels with low-power needs.
The new "no knobs" etch-a-sketch. This development allows children to draw with electronic ink and erase the whole screen with the push of a button. It was created based on technology developed in Ohio (Kent State University). Stated Heikenfeld, "Ohio institutions, namely the University of Cincinnati and Kent State, are international leaders in display and liquid optics technology."
Technology in hot-selling Glow Boards will soon come to signage. Crayola's Glow Board is partially based on UC technology developments, which Crayola then licensed. While the toy allows children to write on a surface that lights up, the technology has many applications, and consumers can expect to see those imminently. These include indoor and outdoor sign displays that when turned off, seem to be clear windows. (Current LCD – liquid crystal display – sign technology requires extremely high power usage, and when turned off, provide nothing more than a non-transparent black background.)
Coming within two years:

An e-device that will consume little power while also providing high function and color (video playing and web browsing) while also featuring good visibility in sunlight. Cautions Heikenfeld, "The color on this first-generation low-power, high-function e-device won't be as bright as what you get today from LCD (liquid crystal display) devices (like the iPad) that consume a lot of power. The color on the new low-power, high-function e-device will be about one third as bright as the color you commonly see on printed materials. Researchers, like those of us at UC, will continue to work to produce the Holy Grail of an e-device: bright color, high function (video and web browsing) with low power usage."
