A Flaw and a Fix for OLED Brightness
Thu May 16, 2013 at 12:30 PM ETTags: OLED, NHK (all tags)
NHK has theorized a way to fix an OLED exposure issue with iOLED.
The National Broadcasting Corporation of Japan, NHK, is troubled by one aspect of OLED. But rather than introduce a problem, NHK has theorized a solution.
OLED pixels, when exposed to open air, can suffer a quick and severe degradation of brightness. In one example from NHK, the OLED pixels fell to 50% of original brightness in just 100 days. Naturally, part of the current challenge for OLED production is to prevent this kind of open air exposure by ensuring that OLED products are correctly sealed.
In contrast, NHK's solution is a two-step shift in OLED design. First the cathode layer needs to be covered with a new material that is less susceptible to moisture and oxygen. This new cathode layer then needs to exchange position with the anode layer in order to display correctly. This exchange in positions is referred to as an inversion, for which NHK has dubbed the design iOLED.
NHK has promised to release full report on its findings at the end of the month, at which time critical analysis by engineers the world can be applied.

Can LG Bring Its Curved OLED TV to Market in 2013?
Thu Apr 18, 2013 at 11:30 AM ETTags: LG, OLED (all tags)
LG working to beat Samsung to market.
The LG EA9800 represents the company's first attempt at a curved image-preserving OLED TV. The 55" "Paper Slim" design attempts to replicate the curved angle of cinema screens that when combined with the set's red, green, blue, and white organic LEDs hopes to increase viewer immersion.
Kyung-Jin Kang, a lead engineer at LG's Home Electronics, "When you go to the cinema the screen is curved. By applying that to the TV you can enjoy being at the cinema in your living room."
Naturally, the 55" screen size is just the beginning. Hung W.K. Shin, Home Electronics Product Communication Team Manger at LG, "We are preparing various types of curved TV. Not only 55-inch models but larger as well. Consumers will be most strongly immersed with this curve."
As LG vies with Samsung, the immediate goal with OLED is to be first to market. Trusted Reviews has derived from several LG interviews that LG EA9800 is being be pushed for release this year, but the exact date is not yet known.
Thomas Lee, LG’s Vice President of Home Entertainment, "curved TVs are coming in the second half of this year."

Panasonic's Last Plasma Panel Powers the New ZT60
Thu Apr 11, 2013 at 10:00 AM ETTags: Panasonic, Plasma TVs (17 posts), OLED (all tags)
Panasonic plans to reuse that panel for models into 2014 while working towards OLED.
Panasonic's ZT60, the company's latest and possibly greatest plasma television, is powered by the company's last plasma panel. Recent reports that Panasonic was abandoning plasma development have been confirmed to a degree, however, the company intends to sell plasma sets built with their current panels into 2014.
Panasonic President Kiyoshi Okamoto told The Verge that Panasonic has shifted its plasma engineers towards OLED development and that "OLED is one of the key future products" for Panasonic. Current costs for OLED production keep the tech from being a definite path for Panasonic, and the company hopes to raise its current business sales in order to reach a healthy bottom line. Panasonic has an OLED development deal in place with fellow troubled manufacturer Sony.
While Panasonic has produced plasma TVs with picture quality to swear by, plasma sales have plummeted while LCD TVs have become ubiquitous. In terms of marketability, plasma sets carry a "burn-in" stigma that often has relegated plasma TVs to an afterthought on sales floors. Meanwhile, LCD and its companion edge-lit LCD from Samsung, LG, and Vizio continue to sell unabated.
The VT60 and VT65, priced at $3000 and $3500, respectively, exist as some of the best display options currently for sale and compare favorably with the hallowed but discontinued Pioneer Kuro Elite 151FD. Panasonic's current plasma line derives from its acquisition of plasma tech from Pioneer.
As the Panasonic ZT60 becomes available later this month, customers will face the choice of buying into a tech that seems to have died well before its time.

Shakedown: Police Enter Samsung Offices in Search of LG OLED Documents
Wed Apr 10, 2013 at 01:00 PM ETTags: Samsung, LG, OLED (all tags)
Samsung spokesperson: "We have no reason to steal other companies’ technology, as we have the world’s best OLED technology."
Yesterday, South Korean police officers searched the offices of Samsung Electronics Co. according to a report from Bloomberg. The search comes as the latest episode of OLED espionage involving both industry leaders Samsung and rival LG.
LG Display is claiming that they did not direct the police towards Samsung, rather that the police have made their own determination with regards to the alleged theft. Son Young Jun, LG Display spokesman, "The latest investigation is related to large-sized OLED TV panel technology, but the police have made the allegation themselves."
Samsung and LG are already connected by police to criminal probes from July. At that time, six LG Display employees were charged with OLED tech-related theft from Samsung. LG has stated that the information in question with the July charges was not secret, and specifically did not contain trade secrets.
In response to inquiries regarding yesterday's visit from the Seoul Metropolitan Police Agency, Jun Eun Sun, a spokesperson for Samsung stated, "We have no reason to steal other companies’ technology, as we have the world’s best OLED technology."
OLED as a marketable technology has more than enough potential to justify concerns with regards to industrial espionage. As companies rush to bring products to market and to eager consumers, policing tends to lag behind, leaving open the possibility that displays may debut as hot products only to have their production and sale frozen while legal battles play out.

Korea Selects LG to Develop a 60-Inch Flexible OLED
Mon Jul 16, 2012 at 12:00 PM ETTags: LG, OLED (all tags)
It's a part of the Future Flagship Program, which aims to create more jobs and income for Korea.
The folks at the Ministry of Knowledge Economy in Korea have selected LG as the company that will lead them into the technological future by developing a 60 inch flexible OLED panel by 2017. The program is designed to create jobs in Korea and strengthen the country's position as a technology leader.
The initial applications for the tech, as you might expect, will be commercial in nature. The sets could be used to wrap around columns to provide directions to passersby or, more likely, to advertise products. There's no word yet on whether a consumer grade flexible OLED will be brought to market, but it seems more prudent to get normal OLEDs out there first.

Panasonic and Sony May Join Forces in OLED Development
Tue May 15, 2012 at 10:00 AM ETTags: Sony, Panasonic, OLED (all tags)
The two companies may be working together to catch up on the OLED front.
Samsung and LG already have plans to put OLED sets on the market this year, which puts Sony and Panasonic in an unenviable position. The technology is coming and at a not-too-ridiculous price, which seems to indicate that OLED will soon be a legitimate threat on the marketplace.
The two companies that are sitting in the backseat of a car that Sony once drove have decided to get together according to Japanese business paper Nikkei. If true, the two will share production techniques and maybe even find a way to bring prices down even more while keeping quality high. Only time will tell.

Samsung Shows Off First Mass-Produced 55 Inch OLEDs
Thu May 10, 2012 at 02:00 PM ETTags: Samsung, OLED (all tags)
It looks like they're going to run right around $9,000 later this year.
After years and years of waiting, we all but gave up on the possibility of OLED TVs ever reaching the market. Our doubts were unfounded, as it turns out, and OLED is a reality. Samsung's 55" OLED set is expected to release in the second half of this year with a price tag in the 10 million won or $9,000 range.
In addition to the picture quality you'd expect from an OLED set, you'll find Smart Dual View technology, which allows you to watch a totally different show than the person next to you, provided you don't mind wearing 3D glasses to watch 2D content. You'll need to rock some headphones too, or else one of you is bound to have a confusing viewing experience.
Samsung says that sets from 60" on up to 75" will be coming in the future.

Samsung is Taking its Super OLED to IFA
Mon Apr 16, 2012 at 12:00 PM ETTags: OLED, Samsung, IFA 2012 (all tags)
Hopefully we'll get a little more information on the impressive new set.
Not too many companies are still seriously pursuing large screen OLED sets, but Samsung seems to be pretty dedicated to the idea. The company brought a TV to CES that they're calling Super OLED and we've been dying to know more since.
The 55 inch Super OLED set will be shown off at the upcoming IFA event and we're hoping to get just a bit more information on it. Specifically, a price and release date would be helpful, especially since LG's 55EM9600 is set to retail at $7900 next month.

DuPont Adds an OLED Research Plant in Delaware
Thu Jan 26, 2012 at 10:00 AM ETTags: DuPont, OLED (all tags)
The facility will allow the company to test new, less expensive ways to bring OLEDs to market.
The folks at DuPont have a goal - to crack the OLED secret. They want to be the ones to find the way to make OLED inexpensive enough to mass produce and sell to regular consumers and they're building a brand new $30 million production facility to do it.
The company will be employing 35 people on the task of exploring new methods of creating OLEDs. DuPont says that it will be keeping the new facility open for at least five years. We're just hoping the investment pays off - reasonably price OLEDs would be nice to see.
