Japanese boffin boasts electrospray OLEDs

As cheap/expensive as newspapers

Displays created using self-illuminating organic light-emitting diode (OLED) technology "could be manufactured as inexpensively as printing newspapers," according to one of the researchers involved in developing the new manufacturing process.

As reported [1] in Nanowerk, one Yutaka Yamagata of the Japanese research center, RIKEN [2], also claims that the new method will also result in displays with better performance than current OLED-based displays.

The new method uses an electrospray-deposited polymer films rather than the spin-coated films used in today's OLEDs, which allows the resulting display to be smoother, and each pixel on it to have a higher intensity, even at lower voltages.

An abstract of the paper, "Thin-Film Fabrication Method for Organic Light-Emitting Diodes Using Electrospray Deposition," can be found here [3], along with a link to purchase the full paper for $49.95.

Although "as inexpensively as printing newspapers" may sound wonderfully cheap, the infrastructure required for printing the daily news is pricey indeed.

That said, this development - if it pans out, and if mass-manufacturing techniques could be developed cost-effectively - could be another step toward the all-OLED future that has been "just around the corner" for a disappointingly long time. ®
