Update: We found two videos (of the color and low-frequency displays), see below

Samsung is showing new Electrowetting 6.2" display prototypes. They are showing 3 different displays - a color reflective one, a mono reflective one and a low frequency one. We don't have any technical information yet...

Update: This is now official, Samsung issued a press release. We still do not know the financial details...

There are reports that Samsung has acquired Liquavista. It's not official, and we do not know the financial details, but it seems that Samsung is already listed as Liquavista's corporate parent at the Netherlands' chamber of commerce.

LiquaVista raised $9.5 million in early 2010, so this doesn't seem to be an "emergency sale" - and is probably good news for the company and the technology. We also know that Samsung stopped making E Ink panels in August 2010 - so perhaps they were already considering the move to Liquavista's electrowetting displays. Here's an interview we conducted with Liquavista's CTO back in March 2010.

Researchers from the University of Cincinnati have demonstrated that regular paper can be a flexible host material for Electrowetting displays. These new displays can theoretically be almost as cheap as printing a normal magazine. They say that in 3-5 years this can actually be commercialized, but these estimates are always optimistic...

The researchers say that paper is the "perfect substrate" for Electrowetting displays: it's flexible and cheap, and shows the same performance as glass.

Liquavista is showing a new flexible electrowetting display prototype. They say that it's unbreakable. They wouldn't say when such displays can be commercialized though:

Researchers from the University of Cincinnati and startup Gamma Dynamics have developed a new Electrofluidic display. The display can retain images without power consumption (like e-paper), has a >70% white reflectance and is fast enough for video. The idea is to use a colored fluid between the front and the backside of a reflective sheet.  The space  above and beneath this special sheet is similar in geometrPixel Structurey enabling the fluid to remain stationary in any position without an applied voltage.

The concept has been realized years ago, but the manufacturing process was only developed recently - in a collaboration between the Univ. of Cincinnati, Gamma Dynamics, DuPont and Sun Chemical.

Check out this nice video showing how Liquavista's displays behave outdoors. This short clip shows a couple of displays and a regular LCD (the laptop in th top-right). The liquavista's display are better, of course:

Liquavista is showing new 8.5" full-color and monochrome displays, available across their entire range of platforms: LiquavistaBright, LiquavistaColor and LiquavistaVivid. The displays offer XGA resolution (1024x768).

Available to partners for evaluation through Liquavista’s partner program, manufacturers and product developers will be able to gain early access to samples.

Liquavista announced a new dynamic frame rate capability down to frequencies as low as 1Hz, resulting in ultra-low power electrowetting display driving.

“Our displays already had increased power efficiency over existing displays due the their remarkable optical efficiency,” said Guy Demuynck, Liquavista’s CEO, “but with the launch of these new dynamic drive schemes, we can enable future devices to improve even further on overall power consumption, without compromising optical performance in all modes from static images, to hi-fidelity video, fulfilling our promise of true mobility.”

Liquavista announced the acquisition of a significant portfolio of IP, which will further strengthen their current electrowetting based display portfolio. They want to become a one-stop-shop for the licensing of electrowetting display technology, and this is a "step forward".

"Our current portfolio already enables us to cover all modes of operation; reflective, transmissive and transflective, as well as providing us with a broad coverage throughout our value proposition” added Johan Feenstra, CTO. “As such, in addition to protecting the core principle of making electrowetting displays in a way that re-uses the current infrastructure, it also covers other areas, including materials and driving methods.".

Liquavista has just raised $9.5 million. We have talked to Johan a few weeks ago, here's the full interview.

Liquavista has announced it has raised $9.5 million in a Series D funding round. Liquavista is expecting products using their technology to arrive in 2011. They make monochrome and color e-paper like displays.

Last month we interviewed their CTO.
