The Batteries Are Low In My Newspaper

Hallo hoppy reader,

Back in October of last year, I blogged about some interesting tech, including display tech. This past week, at a recent D7 Tech DEMO, Plastic Logic CEO Richard Archuleta demo’d his keyboard–free e–reader for the crowd.Light and svelt, the proto appears to be a far cry, design–wise, from Kindle père et fils. In response to concerns from the crowd regarding Amazon’s market lead, Plastic Logic stressed that their product is design for businesspeople.

In other e–reader news, the folks at Dupont’s display division recently announced a tech breakthrough. Organic LEDs or OLED tech is a promising approach to daylight–readable, full color displays. Trouble is, the current cost is relatively high and the yield for large sizes is relatively low. Enter Dupont, a company not normally thought of for display tech. At the recent Society for Information Display (SID) Symposium, in San Antonio, Dupont disclosed new, longer lasting OLED materials for solution–deposition. Sumitomo executives also reported at symposium that they have been shipping solution-printable polymers for displays. OLED polymer semiconductors are usually manufactured by spraying organic semiconductor molecules through a stencil that has nanoscale pinholes in it. Low yields for large areas are the result, hence the largest commercially available OLED display is in a Sony 11″ TV. Some companies, like QD Vision Inc., are attemping to overcome the manufacutring limitations of OLED tech. In QD Vision’s case, they are depositing the light emitting elements by rubber stamp.

What Dupont announced was materials, methodology were not revealed, for use with nozzle–based spray applicators, where each layer of a display’s semiconducting structure are printed using nozzles similar to what a modern, high rez ink jet printer employs. In fact, the printer technology is being supplied by Japanese printer giant Dainippon Screen. Printable OLED displays will significantly reduce manufacturing costs and improve the chances of realizing practical flexible displays. Unlike flying cars, we may actually see rollable e-readers within seven years.

Well, that all for now. Thanks for stopping by and, continue to geek!

  1. This just in… LG announced that a 15″ OLED TV will enter production this summer, with the first products available for their domestic market in December and into January, with worldwide availability to follow soon after. They’ve been showing a proto since early this year. Won Kim, LG’s VP of OLED sales & marketing said that he sees LCD and OLED coexisting in the marketplace until the middle of the next decade. Gradually the foresee OLED displays as taking over due to the “overwhelmingly superior” features and benefits.
    Also, a video of some flexible OLED displays from NHK and Sony has shown up from IDG…interesting. See:

  2. This just in…Last friday, July 17, LG Display’s CEO on Friday said his company plans to build 32″ HD OLED panel TVs in 2012.
