Shin (right) believes that mainstream OLED is a distant dream

At its European Forum event, Samsung Europe's new President and CEO was quick to dispel any doubt about the viability of OLED over the next few years, instead insisting it would be half a decade before we see it hit the mainstream market.

"When it comes to OLED we have several issues to be overcome in terms of technology and production cost issues," said Sang Heung Shin, speaking to the gathered press in Vienna, Austria. "[it will be] at least 4-5 years before we see OLED in the marketplace."

His comments echo the stance of other manufacturers such as Sharp. At CES, Sharp CEO and Chair Doug Koshima was keen to stress that "the present and future is LCD." It's no coincidence, of course: Samsung and Sharp have spent millions on LCD manufacturing facilities and have planned to spend millions more as we saw in our inside look at Samsung's LCD manufacturing plant last year.

Samsung itself had previously indicated that OLED might be viable this year.

Samsung also intimated that it would be concentrating its efforts on ever larger screen sizes, even though some markets still demand smaller sizes in large quantities. "There's still some strong demand in some countries for 32-inch," said Hadrian Baumann, Director of European marketing at the company.

"We have seen an explosion in the market for 40-inch and above. I can tell you that 40-and 46-inch [sets] are extremely popular. The perception was that [the market was] too small, but it is a market we are very bullish about. [We'll be] focusing on the larger sizes."

"We have great expectations that we will be very successful in the years to come," added Kim. "We want to be a technology leader in the 21st century." Shin also feels there are some sectors that can grow well over the next year. "The printer and notebook PC markets, in particular, offer high growth potential."

"Our 2009 product lines represent a new generation of converged products that blend technology with the active lifestyles of European consumers," added Shin as he eulogised about the company's new kit and strategy for growth in the year ahead.

Samsung also introduced its new netbooks at the event, as well as other products including its new 8000, 7000 and 6000 LED TV ranges that we reported on the launch of at CES in January.

Panasonic and Sumitomo see eye to eye in this OLED game, big screens due in 2010

Ready with the proper retort to all those rumors, false starts and misquotations, the Nikkei is reporting that Panasonic and Sumitomo are zeroed in and have the tunnel vision to deliver the 40-inch plus OLED HDTVs we've been waiting for within fiscal 2010. Once organic electroluminescent product is flooding the streets, the plan is apparently to cut the power requirements of the bright, slim displays to less than a third of current LCDs by 2015, right around the time Samsung thinks this tech will be ready for the mainstream, anyone else care to make a prediction?

Euhm... hust... hust...
Da wird noch so ganz am Rande erwähnt, dass die (derzeitigen) OLEDs eine kürzere Lebensdauer haben. So um die 20'000 Stunden rum bei normaler Nutzung...

Da warte ich doch lieber noch [...]
Bist Du sicher, dass der Röhrenfernseher eine längere Lebensdauer hat?

20'000h tönt nach wenig. Das sind bei 3h TV-Schauen pro Tag etwa 20 Jahre Lebensdauer...

Nach so einer langen Betriebsdauer macht schon manches UE-Gerät schlapp.

Die Frage (nicht nur) bei den OLEDs ist, wie stark die Qualität über die Betriebsdauer degradiert.

 
LG Display Plans to Release 40-inch OLED Panel in 2012

The 15-inch OLED TV exhibited at FPD International 2009

LG Display Co Ltd announced its roadmap for developing and releasing large-size OLED panels at FPD International 2009, which takes place from Oct 28 to 30, 2009, at Pacifico Yokohama, Yokohama City, Japan.

Won Kim, LG Display's OLED sales and marketing VP, took the podium.

LG Electronics Inc plans to release a 15-inch OLED TV with a panel developed by LG Display at the end of 2009. The panel has a pixel count of 1,366 x 768 and a resolution of 105ppi. Its maximum screen luminance with an all-white signal and an all-black signal are 200cd/m2 and 0.01cd/m2, respectively. The peak luminance is 450cd/m2.

The panel is a bottom emission type and uses low-temperature polycrystal Si-TFTs that are crystallized by a high-temperature process (solid phase crystallization or SPC) as driver elements. Those specifications were announced at IMID 2009, a trade show that took place in October 2009 in Korea.

After the 15-inch panel, LG Display plans to release 20-inch and larger OLED panels in 2010, 30-inch and larger panels in 2011 and 40-inch and larger panels in 2012.

"Forty-inch and larger OLED panels will be fairly expensive in 2012, but they will be available in the market," Kim said.

'OLED panels will cost less than LCD panels in 2016'

In regard to technical challenges to stably supplying large-size OLED panels at low cost, Kim mentioned (1) driver elements (TFTs), (2) organic EL materials and film forming processes and (3) sealing processes.

Driver element

As for driver elements, LG Display will probably employ a TFT based on a low-temperature polycrystal silicon (and SPC method) or an oxide semiconductor such as IGZO (In-Ga-Zn-O), he said. However, he also said that TFTs based on those materials have some problems.

"We will be able to use a low-temperature polycrystal silicon with the sixth-generation size glass substrate," Kim said. "However, for 40-inch and larger panels, we have to use the eighth-generation size glass substrate. Therefore, we have to develop equipment that can deal with an SPC process at a temperature of more than 700°C."

As for oxide semiconductor, he said that it is one of the candidate materials to be used for large panels. But it has low reproducibility because of variation among lots, he said.

Organic EL material / Sealing process

LG Display plans to use fluorescent materials until 2011 and phosphorescent materials thereafter. Also, as film forming processes, the company is considering using printing technologies, starting from an evaporation method with a metal stencil mask.

"In regard to sealing process, we believe that solid sealing is desirable for TV panels," Kim said.

With those measures, LG Display aims to achieve a 50% higher material cost and a 30% lower yield than those of LCD panels in 2012 and a 20-30% lower material cost and an equivalent yield in 2016.

At the exhibition site, the company exhibited the 15-inch OLED display, which was unveiled at IMID 2009, for the first time in Japan.
