Holst, IMEC work on flexible OLED displays

LONDON – A program of research into flexible organic light emitting diode (OLED) displays has begun at Holst Center (Eindhoven, The Netherlands) and IMEC (Leuven, Belgium).
OLEDs are already used in small, mobile applications such as smartphones and tablet computers where they are liked for their rich colors, high contrast and lower power consumption than LCD. OLEDs also have a faster response time than LCD and better viewing angle. OLED displays are also simpler in design and require fewer support components thereby enabling manufacturing cost reductions.
To these attributes Holst, IMEC and program participants such as Polymer Vision, a subsidiary of Wistron Corp. (Taipei, Taiwan), want to add mechanical flexibility and a thin-film transistor (TFT) backplane for addressability. IMEC and Holst did not reveal any other industrial participants in the program.
The program scope includes redesign of support transistors and development of manufacturing equipment for backplanes and roll-to-roll manufacturing. No indication was given for size, resolution or dot-per-inch goals for the research, or how long the program is expected to last.

Flexible OLED display developed in collaboration with Polymer Vision, one of the industrial partners in the shared programs at Holst Centre and IMEC.
"With this program in mind, we already have been working more and more towards integrating separate building blocks and have realized OLED displays using both organic and metal oxide TFT backplanes," said Paul Heremans, OLED display program manager, in a statement. "Thin, plastic substrates were used, and the displays were fully encapsulated using our state-of-the-art barrier technology." He added that display prototypes would be demonstrated in 2012.
Gerwin Gelinck is Heremans' opposite number at Holst Centre.

It would be great if we see much better and cheaper displays in the future.

Traditionally, OLED have suffered from expensive manufacturing processes, and some issues with reliability. Not sure what this alliance will do about that?

OLED manufacturing just got a whole lot easier. We have developed at Colnatec a process control sensor for OLED production. The sensor is Angstrom level accurate, self regenerating (cleaning) for continuous production and solves many of the thermal issues associated with the evaporation sources in OLED systems. First products will be in beta test in 1 month

Care to share details with nicolas.mokhoff@ubm.com? Sure would be interesting to write this up.

The last color OLED display I tried was very pretty but had visible burn-in after one month. So I'd run an OLED for a month or two before qualifying it.

If these can be built, we should be able to get a display that rolls up like a scroll, similar to the one in the movie Red Planet, used by Val Kilmer.
Science fiction leads again!
Seriously...such a display should make very thin wall mounted displays as well.

The developments are finding it way for OLED, LEDs are going to be the driving force for the next generations, infect LCDs limitations can be greatly overcome by this technology but still it has many acceptance test to get pass through.
