Carmack, Romero, Kutaragi, Miyamoto, Molyneux, Meier, Wright...all better examples of the "gods" of gaming.

If I'm going to idolize someone, it better be someone amazing. If, as a geek, I'm going to idolize someone, it'll be a notable creator. Wheaton's just a 30-something adult geek with a family and a blog - not exactly amazing or accomplished. The only thing making him notable is his former role as Wesley Crusher, and that doesn't make him awesome, it makes him LAME.

For the same reason I think Dustin Diamond is lame and doesn't deserve the spotlight he occasionally receives these days.

OLEDs enjoy growing demand
12 September 2007

Dubbed next-generation displays in the industry, organic light-emitting diodes are flourishing in the display market, at least in terms of revenue and shipments, a report said yesterday.

According to the quarterly OLED shipment and forecast report by the market research group DisplaySearch, the OLED market grew 24 percent in the second quarter from a year ago, hitting the 19.8 million mark in total shipments.

The combined revenue from OLEDs reached $123.4 million in the second quarter, up 13 percent from a year ago, the report showed.

"As OLED displays become more prevalent in key small and medium display applications like mobile phones, main displays and sub-displays, MP3s and automotive consoles, they become increasingly competitive in comparison with LCDs," said DisplaySearch senior vice president Barry Young in a statement.

OLEDs produce brighter colors, higher contrast ratios and have a broader viewing angle than LCDs. OLED pixels directly emit light whereas LCDs have to use backlights.

"Over the next year, we are expecting revenues to grow by 117 percent due to the introduction of AMOLED (active matrix OLED) displays for mobile phones and digital cameras, plus the added number of suppliers including TPO, LG.Philips LCD and Casio," Young said.

The report said that AMOLEDs are beginning to impact the market as Samsung SDI, the world's top OLED manufacturer, becomes the first company to reach full production of AMOLEDs.

"We have completed the preparation for mass production of 2-inch class AMOLEDs. We cannot disclose the exact date but it is going to be very soon," said Samsung SDI spokesman Seo Hae-soo.

Also, Sony previously had announced that the Japanese electronics giant will mass-produce 11-inch AMOLED TV displays.

AMOLEDs perform much better in video pictures than typical OLEDs.

Separately, Samsung Electronics president of its digital media business, Park Jong-woo, said Samsung is developing 30-inch OLED TVs and plans to release them by 2010, during the consumer electronics trade fair IFA 2007 in Berlin last week.

Regarding any plans to produce OLED displays, an LG.Philips LCD official said the company had previously reviewed the matter but has not come up with a specific plan yet.

"The reason we are still reviewing the matter has nothing to do with technology. We are still closely watching market movements," the officials said, asking not to be named.

Sharp says Pioneer deal a ’strategic alliance’
20 September 2007

Mikio Katayama, president and COO of Sharp describes his shock deal with Pioneer as a “strategic business alliance,” citing rapid changes in technology and harsh global competition as a reason for the move. Katayama says: “it is not an exaggeration to say that we cannot predict one year ahead, or half a year, or even three months ahead.”

The two have announced that they will jointly develop OLED display technology, and co-develop mobile technology products. Sharp currently depends on LCD for more than 70 percent of its profit, but such dependency makes it vulnerable to changes in the LCD market. With Pioneer's expertise, it plans on broadening its range and diversifying. Sharp is now the top shareholder in Pioneer.

OLED-T Green OLED Emitter Offers World Class Efficiency Performance
25 September 2007

OLED-T today announced a green phosphorescent OLED material with world class efficiency performance.
The new material called E255a has a high colour saturation making it ideal for a broad range of product applications in single colour and full colour displays. The material also has a very high efficiency delivering high brightness at low power making it ideal for mobile product applications with either passive matrix or active matrix driving.

The University of Hong Kong has manufactured OLED demonstrators using E255a and has reported a device efficiency of 40 cd/A at 1000 cdm-2 with a very saturated green colour coordinate of (0.28, 0.64) which is wider than commercially available LCD products.

E225a will be available for customer sampling from January 2008 and can be deposited onto any desired substrate by vacuum coating methods.

OLEDs storm consumer space
9 October 2007

Sony and Samsung are both making moves to bring OLED displays to a larger commercial audience. In Sony's case, the target is the television. In Samsung's, it's portable devices.

Sony Corp. will launch an 11-inch ultrathin flat TV with an organic LED display in Japan in December. The model is purported to be the first TV to employ OLED technology. It will vie for a share of an $82 billion market dominated by LCD and plasma panels.

Meanwhile Samsung SDI this week will announce its intention to produce the world's first 3-inch WVGA (480 x 800) active-matrix (AM) OLED panel, using PenTile subpixel rendering technology from Clairvoyante Inc.

Sony's OLED TV will be a commercial breakthrough. The technology's characteristics of energy efficiency, thin size and light weight amount to a crisp picture that Sony said is now suitable for showing fast-moving images from sports events and action movies.

"I want the world's first OLED TV to be the symbol of the revival of Sony's technological prowess. I want this to be the flag under which we charge forward to turn our fortunes around," Sony president Ryoji Chubachi said at a news conference at the company's headquarters, in Tokyo.

But size is still a limitation for OLED technology.

"It seems like it is more about technological leadership than something that can actually have an impact on the TV market," said Paul Semenza, vice president for displays at market research firm iSuppli Corp. Semenza said Sony caused a stir at the International Consumer Electronics Show in January when it showed an OLED prototype display, "which is truly stunning. But in 2007, 11 inches is not a TV; it is a mobile device."

Sony, the world's second-largest maker of LCD TVs (behind Samsung), expects the 11-inch OLED TV to sell for $1,700--almost as high as retail prices of some of its own 40-inch LCD models.

Large-OLED-panel manufacturing is difficult, which limits OLED's appeal as a common display for next-generation TVs. LCD panels dominate, and TV makers are showing LCD and plasma prototypes with much larger panels than OLEDs have achieved to date. Matsushita is even offering 103-inch plasma TVs, while LCD TV makers are offering 40-inch sets, moving up from the predominant 30-inch models.

"I don't think OLED TVs will replace LCD TVs overnight. But I do believe this is a type of technology with very high potential, something that will come after LCD TVs," Sony executive deputy president Katsumi Ihara told reporters at the Tokyo announcement, which was made just before the opening of Ceatec (the Combined Exhibition of Advanced Technologies Providing Images, Information and Communications), Asia's largest annual electronics and communications industry event.

Ihara said he set the price tag of about $1,700 without paying much attention to profitability, suggesting perhaps that Sony is willing to take a loss on each set it sells, at least initially. The TV will go on sale in Japan Dec. 1.

Worth the price?

The set's life span of about 30,000 hours of viewing is roughly half that of Sony's LCD TVs, but long enough to allow eight hours of daily use for 10 years, according to the company. Sony will limit monthly production to 2,000 units, compared with its plans to sell 10 million units of LCD TVs in the year through next March.

"The price is obviously an issue, and the fact that they might not be making a profit on a $1,700 11-inch display says a lot about how far they have to go on cost competitiveness," said iSuppli's Semenza. He pointed out that the lifetime of 30,000 hours could be viewed as considerable "if it was the point at which users started to notice degrading brightness or color shifts." However, he said, Sony could be quoting the set's total useful lifetime, "which suggests that consumers might start to notice changes within 10,000 or 20,000 hours, which is not so good."

"The biggest limitation that active matrix OLED has is the lack of maturity in the manufacturing process and the very limited manufacturing capacity overall," Semenza said. By contrast, the LCD industry has multiple sixth-, seventh- and soon eighth-generation fabs, each of which can produce millions of 30-, 40- and 50-inch TV panels per year. A small number of pilot and fourth-generation lines exist for AM OLEDs. These lines can have an impact on mobile phones and PMPs, but not on TVs, Semenza said.

Samsung's clear choice

In partnering with Clairvoyante--the other 800-pound gorilla in the OLED space--Samsung hopes to overcome performance and manufacturing challenges typical of high-resolution OLED panels.

By incorporating Clairvoyante's PenTile RGB technology, Samsung intends to develop the first handheld WVGA RGB OLED panel. To date, OLED displays for portable computers and mobile devices have been available only in formats up to QVGA (240 x 320). PenTile technology makes it possible to attain WVGA performance by eliminating one-third of the subpixels while maintaining the same display resolution.

Anticipating a strong demand for OLED technology, Samsung recently invested in additional capacity. Industry research group Display Search predicts that the AM OLED market will grow to $5.58 billion by 2011, up from $220.5 million in 2007. Samsung has been fabricating OLED panels since August 2002 for applications in car audio systems, electronic games, MP3 players and, now, cell phones.

"Our partnership with Clairvoyante will create a PenTile OLED panel that will lead the handheld market with a power-efficient, high-resolution OLED panel that supports continued innovation in emerging handheld applications," said Sung-Chul Kim, vice president of Samsung SDI.

Samples of the Samsung panels will be available in the first quarter of 2008, with mass production slated for the third quarter. The new module will be demonstrated later this month at Flat Panel Display International in Yokohama, Japan.

"Samsung SDI's commitment to supporting the growing OLED market will result in small/medium displays that are increasingly competitive with LCDs," said Joel Pollack, president and CEO of Clairvoyante. "Using PenTile technology, Samsung SDI can more quickly capitalize on this market growth by overcoming production hurdles to create high-resolution displays."

Samsung SDI Starts Mass-Producing AMOLED Displays
11 October 2007



Samsung SDI has succeeded in mass-producing AMOLED displays.


Samsung SDI has won the race to start mass-producing a next-generation display screen using active-matrix light-emitting diodes or AMOLED. AMOLED is clearer than the LCD or PDP formats currently used for display screens to a point where the display screen remains clear even under direct sunlight. Electronics companies all over the world have been racing to mass-produce it.

Now South Korean electronics companies can outdistance their Japanese or American rivals. At present, LG Philips LCD, Sony and Toshiba Matsushita Display Technology (TMD) are shaping up to mass-produce AMOLED screens, touted as the future of mobile displays. The size of the market is expected to reach US$3.6 billion (about W3.4 trillion) by 2011.

In a press conference at Samsung SDI's Cheonan Plant, a company spokesman said, "We've received orders from manufacturers of mobile phones or video gadgets for up to 90 percent of next year's production.” Samsung SDI already supplies the product to domestic MP3 player maker Reigncom and has reportedly signed a supply contract with the world's top mobile phone maker Nokia.

Kim Jae-wook, the head of Samsung SDI's display business, said the firm plans to increase its monthly 2-inch AMOLED screen production capacity from the current 1.5 million units to 3 million in 2008. A Samsung SDI spokesman claimed the company has made “a new breakthrough” after sluggish performance in the cathode ray and PDP TV business.

The company’s mass production of AMOLED displays has spurred domestic and foreign display manufacturers to gain a slice of the market. Sony, overtaken by Korean firms in the market for PDP and LCD display screens, has recently produced digital TVs using AMOLED in what looked like an attempt to retrieve its reputation. Despite being only an 11-inch prototype, Sony's product is attracting attention from the industry, and the firm has announced it will produce and sell 1,000 units per month from the end of the year.

TMD is also busy preparing to mass-produce AMOLED. The LG Group has recently put LG Philips LCD in sole charge of the AMOLED project earlier carried out jointly by LG Electronics and LG Philips LCD.

But if AMOLED manufacturers are to take the initiative in the display market, they need to make at least 20-inch monitor screens and 30 to 40-inch screens for digital TVs at affordable prices. The industry predicts that the day will come in four to five years.

Samsung SDI's Kim Jae-wook said, "We've already finished development of AMOLED for 17-inch TVs. The question is whether we can supply them at a competitive price or earn profits, so we'll decide whether to advance into the AMOLED TV market in earnest after studying the market situation."

The OLED gold rush begins
13 October 2007

The great OLED gold rush is on. With both Sony and Samsung SDI making the running with the next generation display technology, other panel-makers are keen to play catch-up. The world’s second-biggest maker of panels, joint-venture company LG.Philips is negotiating with LG Electronics to acquire its OLED division. Kwon Young-soo, CEO of LG.Philips, says he expects to obtain the operation early 2008.

Seiko Epson to enter ultra-thin panel business
14 October 2007

TOKYO: Japan's Seiko Epson Corp plans to make ultra-thin flat displays based on organic light-emitting diode technology (OLED) after it expanded the lifespan of the panels, a daily said on Sunday.

The electronics maker has a production line at its Nagano plant and aims to take orders for OLED panels by the end of the year. The plant is capable of manufacturing several thousand OLED panels a year, the daily said.

The company has expanded the life span of OLED panels to more than 50,000 hours compared with the maximum life of standard OLED devices, which is typically 30,000 hours, Nikkei said.

OLED panels, which emit light when an electrical charge is passed through the surface, are lighter and thinner than existing LCD panels or plasma displays, and boast higher contrast pictures, but are also more expensive.

The company plans to start making an eight-inch business-use OLED monitor that is 2.8 millimetre thick at its thinnest part. The production line is also capable of manufacturing larger models of up to 21 inches, the daily said.

Seiko Epson set to enter OEL panel battleground
15 October 2007

Seiko Epson Corp plans to enter the organic electroluminescent (OEL) panels business in a move seen as increasing already severe competition in the flat-panel display sector, a report said yesterday.

Seiko Epson was seeking to take orders for the panels by the end of the year, as it has succeeded in extending the life span of OEL panels to compete with liquid-crystal-display (LCD) and plasma displays, the Nikkei Shimbun said, citing unnamed company sources.

OEL display panels use less power and offer brighter images and wider viewing angles than liquid crystal display panels.

However, the maximum life span of standard OEL devices is typically 30,000 hours, far fewer than the 60,000 hours for LCD and standard plasma displays.

Seiko Epson has now found a way to nearly double the life span of OEL panels to more than 50,000 hours, it said.

The company plans to start its OEL production with an eight-inch business-use monitor that is 2.8mm-thick at its thinnest part in its plant in Nagano Prefecture, the report said.

The company anticipates demand from stores and other commercial facilities as well as for use as monitors in car navigation systems, it said.

Rivalry over the booming global demand for flat-screen TVs has been intensifying among Japanese companies.

Electronics giant Sony Corp has said it plans to begin selling the world's first OEL television in December at a price of ¥200,000 (US$1,700).

Sony's next generation TV has a screen with a thickness of just 3mm, which was made possible because the organic display is self-luminescent and does not require a backlight.

Sharp Corp, the world's largest maker of LCD displays, said in August it had developed a 52-inch LCD TV that is just 2cm thick.

[FPD International] Epson Develops Long-Life OLED Display System; Produces "Ultimate Black"
16 October 2007




Seiko Epson Corp has developed an organic light-emitting diode (OLED) display system said to be capable of producing "the ultimate black". The light emitting capabilities of OLED displays make possible such features as high contrast, wide viewing angles, and fast response times. In addition, the display can be made very thin and lightweight.

To realize the high-quality representation of textures, Epson has been uncompromising in its efforts to achieve "ultimate black" since it is black that holds the key to overall image quality. Furthermore, the problem of early stage brightness deterioration, until now the major obstacle to extending the life of the device, was solved by improving the light-emitting materials and through the development of the company's own original element structure. As a result, the life of the device is lengthened to more than 50,000 hours, a level appropriate for practical application.

Epson has already installed and commenced operations of a development and manufacturing line that is capable of small-scale production at its Fujimi Plant in Nagano prefecture, Japan.

The company will showcase the OLED panel as a reference exhibit at FPD International 2007, which will open Oct 24, 2007, in Yokohama City, Japan.

[FPD International] Tokki, GE Co-develop Film Sealing Equipment for Organic EL Devices
23 October 2007



Samples made with the film sealing equipment. The luminous layer is about
1 × 1cm. Sealing films cover the luminous layers. Transparent ITO electrodes look
like crossing at right angles on the luminous layers.


Tokki Corp prototyped a plasma CVD (chemical vapor deposition) film sealing equipment for organic EL devices and confirmed its ability by sealing some organic EL layers. The company has been developing the equipment with GE Global Research, central laboratory of General Electric Co of the US.

By improving the productivity of the equipment, Tokki aims to release sealing equipments for mass production of organic EL devices within 2008. Compared with glass sealing, which is currently used, film sealing enables to reduce the number of parts and devices and can be applied to flexible panels, the company said.

The prototype of the equipment will be exhibited at FPD International 2007 from Oct 24, 2007, at Pacifico Yokohama, Yokohama City, Japan.

The newly-developed sealing equipment can be used for the fourth-generation glass substrates (730 × 920mm), which the company's other organic EL device manufacturing equipments can deal with. The verification of the technology was conducted with a 200 × 200mm glass substrate.

An Alq3 organic EL layer, which is about 1 × 1cm and sandwiched between transparent ITO electrodes, was formed on the glass substrate. Then, thin sealing films of several nanometers thick were accumulated on the layer.

The sealing films were developed by GE Global Research. Several organic and inorganic layers are piled up to form a barrier film that prevents a luminous layer from deteriorating by protecting it from humidity and gases.

Compositions of the organic and inorganic layers are gradually changed to form a film so that the degree of adhesion between layers increases. And the high degree of adhesion will help to prevent cracks on the film when it is used for flexible substrates in the future, the company said. Its gas barrier ability is in the level of 10-6g/m2 per day.

Film sealing does not need sealing glass, adhesive, desiccant agent and others. Also, film sealing enables to make thinner devices because it does not require glass.

Glass sealing requires about five processes such as cleaning sealing glass and vacuum degassing in addition to automated transportation systems between those processes. In film sealing, only one process, vacuum chamber, is needed.

"We want to cut the price of the equipment by half (compared with glass sealing equipments)," said Osamu Oshinden, senior manager of the corporate planning department in Tokki.

To achieve this goal, in the second stage of the joint development, settings will be adjusted to improve productivity by reducing takt time and using larger substrates, he said. The first target will be OLED panels, but flexible OLED panels and OLED lamps will be the next targets, he added.

Tokki and GE announced in January 2007 that they launched a one-year joint development project toward the practical use of film sealing technologies for organic EL devices.

CMEL to expand OLED production
25 October 2007



CMEL exhibits a 25-inch AMOLED panel at the ongoing FPD International 2007 in Japan


Chi Mei EL Corporation (CMEL), a subsidiary of Chi Mei Optoelectronics (CMO), has announced that the company will invest NT$1 billion (US$30.6 million) to expand to a second OLED production line. Volume production is slated for 2008, said CMO president Chao-Yang Ho.

As present order amount at the company is higher than its available capacity, CMEL thus decided to expand its OLED panel production, and plans to begin volume production at the expansion in the third quarter of 2008. The second line will house a monthly capacity of 700,000 2-inch equivalent panels, Ho detailed. CMEL currently mainly produces OLED panels at 2.4- and 2.8-inch with yields averaging above 65%. Handset vendors from China and Korea are key customers of the company.

Besides the planned expansion, Ho said CMEL will introduce a 4.3-inch OLED panel during the first quarter of 2008. Another OLED panel sized at 7.6-inch will be launched in the second quarter, he added. Ho further noted that when the second OLED production line starts operation, CMEL will also introduce 11- and 12-inch panel production and expects to offer 32-inch AMOLED panels during 2010.

At Flat Panel Display International 2007, It is Not Business as Usual
25 October 2007

I am writing this in Yokohama, where Flat Panel Display International (FPDI) 2007 is in full swing. There is more than the usual level of excitement here, and that’s not only because the flat-panel display industry is rapidly growing and (finally) highly profitable. There is also the sense that exciting technical changes are afoot. In short, this is not just evolutionary business as usual.

For one thing, there are lots of active-matrix OLEDs here, with Samsung SDI and CMEL presenting a range of small AMOLEDs that are in volume production now. CMEL’s displays are being made with a non-laser annealing process for making the low-temperature polysilicon (LTPS) backplane, which is a very significant development because it offers a clear path to shattering one half of Gen 4 limitation that currently afflicts AMOLED manufacturing and keeps costs higher than those for roughly equivalent LCDs. LG.Philips LCD was also showing a display fabricated with a furnace-based crystallization process that will not heat standard display glass beyond its yield point. Unlike CMEL, LPL’s process does not use a catalyst, but LPL is still in the demonstration phase. We may see some furnace-based LPL product next year.

[FPD International] Samsung SDI VP Indicates OLED Panel Roadmap in Keynote Session
29 October 2007



Samsung SDI's OLED Products roadmap


"It is Samsung SDI that is supplying OLED panel products now," said Ho Kyoon Chung, executive vice president and CTO, Corporate R&D Center, Samsung SDI Co Ltd of Korea, in the FPD Summit (keynote session) at the "FPD International 2007 Forum" October 24.

He presented the company's OLED panel roadmap and said, "OLED panels have opened the new era of organic optoelectronics. Not only displays but also new applications such as OLED lighting systems, organic electro-luminescent power generators and organic sensors will emerge in the near future."

"In the mobile display industry, the shift from monochrome to color displays formed the first wave, the realization of high-resolution TFT panels made the second wave and active matrix OLED panels will be the third wave," Chung said. "The OLED panel market will grow to US$3.7 billion in 2010."

Regarding the company's production scale, "We initiated OLED panel volume production in September 2007 and our current output is 1.5 million units per month on a 2-inch panel basis," he said. "The output will reach 3 million units per month in 2008.".

Explaining the company's product development roadmap, Chung said, "Following small panels used in 2007, 3.5- to 7-inch panels including 4.1-inch panels will be applied to ultra mobile PCs, for example, in 2008. Then we will realize 14-, 15- and 21-inch panels in 2009 and large 40- to 42-inch full HD (high definition) OLED TVs in 2010."

"We will provide a flexible OLED display by 2012 at the latest," he added.

As for OLED lighting systems, Chung said, "It won't be long before we commercialize them," because the OLED's light emitting efficiency is currently doubling every year. The company currently achieves 50lm/W luminance, a life of 20,000 hours till the initial luminance halves and a color rendering property of more than 80 colors.

"Our cost goal is 1 euro cent per lumen," said Chung.

Sony OLED HDTVs May Come to America This Year
2 November 2007

Sony says OLED HDTVs could see America stores this year depending on Japanese demand

Many home theater enthusiasts have high hopes for OLED technology -- hopes that not only will OLED HDTV sets require less power but that they also will be significantly thinner and provide better color reproduction and image quality.

Engadget is reporting that Sony Electronics President Stan Glasgow revealed in talks this morning with journalists at the Sony Club in New York that, “OLED could come (to the U.S.) before the end of the year." The catch is that OLED HDTVs coming to America is dependent on the demand in Japan and panel supply. In other words if Sony’s OLED XEL-1 is a big hit in Japan, we won’t be seeing them this year in America.

Sony announced its 3mm thick XEL-1 OLED HDTV almost exactly one month ago to lustful stares from home theater fans around the world. The screen size was small at 11-inches and the price was high at about $1744 USD. The Sony XEL-1 OLED TV left many outside Japan reaching for their wallets only to be told the TV wasn’t available outside Japan.

There have been several other announcements in the OLED arena recently with Toshiba announcing that it would have 30-inch OLED HDTVs on the market by 2009. Toshiba, however, stated that the problem with OLED technology was that the method for producing the OLED panels was immature accounting for the increased cost and longer lead times before panels were available.

Just last week Samsung’s Executive Vice President and CTO, Ho Kyoon Chung, unveiled its roadmap for OLED products. Samsung expects to have 40 to 42-inch OLED panels on the market by 2010.

While Toshiba and Samsung make promises to get OLED HDTVs into the hands of consumers, Sony is actually doing it.

UPDATE 2-Canon to take majority stake in Tokki for $69 mln
13 November 2007

TOKYO, Nov 13 (Reuters) - Canon Inc said it aims to take a majority stake in Tokki Corp, a supplier of flat panel-making equipment, for $69 million or more to speed development of organic light-emitting diode (OLED) panels.

Canon has been developing OLED panels in a bid to replace liquid crystal display (LCD) panels, which it now procures from outside suppliers for digital camera, camcorder and printer displays.

Canon is the world's largest digital camera maker competing with Sony Corp and Olympus Corp, while Tokki is the world's No.1 maker of tools used to make OLED displays.

Canon will offer 556 yen per share in a tender offer planned for 20 working days between Nov. 14 and Dec. 12, aiming to buy at least 3.07 million shares. The offer price is at a 22 percent premium over Tokki's closing price on Tuesday.

The Tokyo-based company also plans to buy 14.2 million new Tokki shares in a third-party allocation, paying 417 yen per share.

In total, Canon aims to take at least a 51 stake in Tokki for 7.6 billion yen ($69 million) or more.

OLED displays use organic, or carbon-containing, compounds that emit light when electricity is applied. Unlike LCD panels, they do not need backlighting, making OLED panels slimmer and more energy-efficient.

OLED panels also offer bright colours and images that are easy to see outdoors, an ideal trait for camera displays.

Canon said it may offer small-sized flat TVs using OLED displays in the future.

For the large-sized TV market, Canon has been developing another type of flat panel TVs based on surface-conduction electron-emitter display (SED) technology.

Ahead of the announcement, shares in Canon closed down 1.3 percent at 5,360 yen, while Tokki was down 1.5 percent at 456 yen, underperforming the Nikkei average, which fell 0.5 percent. ($1=110.09 Yen)

Sony's XEL-1 OLED TV pre-sales begin in Japan
14 November 2007

While it's not scheduled for release until December 1st, Sony is now taking pre-orders for its super-slim XEL-1 OLED TV. Japan only, though we're hopeful for a US release too. Sure, it costs ¥200,000 (about $1,800) for 11-inches of set that will only last about 30,000 hours -- less than that of an LCD. Still, that's only $0.0018 per unit of its 1M:1 contrast ratio. See, affordable.

OLED chemists have a bright idea
23 November 2007



A pixel made from the new material, which can emit red,
green and blue light, allows OLED devices to comprise only two layers


Organic light-emitting diodes (OLEDs) can be made more cheaply and easily thanks to a new molecule made by Chinese chemists. OLEDs use less power than liquid crystal displays (LCDs) and can be made much thinner, so making them cheaper and longer-lasting is important for the electronics industry.

Most OLED materials need several layers to provide a flow of electrons and 'holes', or spaces where electrons can move into, and other layers to stop the flow of electrons or holes in the right places. But the new molecule improves on current OLED designs by performing several necessary electronic functions in just one layer. It can also be treated to emit all the colours required for laptop and mobile phone displays.

The new molecule comprises a quinoxaline group, which accepts electrons very readily, and bulky polyphenyl groups, which stop the molecules sticking together and losing energy by nonradiative pathways - this means it can take the place of several layers in the OLED.

The work provides 'a simple and effective approach to construct[ing] highly efficient and multicoloured OLEDs,' the researchers say. One of the authors of the paper, Yunqi Liu of the Beijing National Laboratory for Molecular Sciences, Beijing, told Chemistry World: 'Our research opens a way for designing and applying multifunctional materials in OLEDs to simplify the fabrication process.'

But John de Mello, senior lecturer in nanomaterials at Imperial College London, UK, suggests the material isn't ready to use on a commercial basis. 'This is a very interesting approach to colour tuning in organic light-emitting diodes, although one that may require further optimisation for practical use,' he said. 'The devices appear to have rather high current and voltage demands, which suggests alternative materials systems may be needed to achieve adequate power efficiencies.'

Toshiba shelves plan to sell OLED TVs in 2009/10
10 December 2007

TOKYO, Dec 11 (Reuters) - Japan's Toshiba Corp said on Tuesday it has shelved plans to sell ultra-thin OLED (organic light-emitting diode) TVs in 2009/10 because of the cost of mass production.
Toshiba will stick to its plans to make OLED displays for mobile phones and will see if making OLED TVs is financially viable later, Toshiba spokesman Keisuke Ohmori said. (Reporting by Mayumi Negishi)

Is there room for OLED technology in the TV market?
11 December 2007



Source: iSuppli, compiled by Digitimes, December 2007


After examining Sony's 11-inch OLED (organic light emitting diode) TV exhibited at iSuppli's Flat Information Displays (FID) 2007 conference last week, there is no denying how stunning the picture is. But because the OLED TV market is still in its infancy, with the Sony set being the first to be manufactured and sold to consumers, it's unreasonable to expect it to compete effectively with LCD or PDP (plasma display panel) TVs at this time, according to research firm iSuppli.

However, this begs the question: Will OLED TV ever be able to match up with LCD and PDP TVs?

"It will be a challenge for OLED to catch up, given the investments that have been put into the other technologies," said Paul Semenza, vice president of displays at iSuppli, speaking at FID 2007 last week. "But there is no doubt about its performance and there is a lot of potential for the display technology, maybe in mobile applications."

With Sony being the first to throw its hat into the OLED TV ring, due to its introduction of the 11-inch set this month in Japan at a price of US$1,800, shipment volumes are expected to be very small, targeting a small niche of well-heeled, tech-savvy consumers.

And even at such a high price, Sony indicated that it is taking a loss on the sale of each OLED set, according to Vinita Jakhanwal, principal analyst for mobile displays at iSuppli.

A few more brands are likely to enter the OLED TV market in 2009, including Toshiba and Panasonic. The major motivation for these companies' entrance into the market is to make a statement to the industry that they are capable of producing OLED TVs, Jakhanwal added.

OLED problems and benefits

Semenza stressed that despite the obstacles, iSuppli does not discount the prospects and potential of OLED technology. However, there are a number of fundamental technology and market challenges that must be resolved before OLEDs can make a real impact in the market.

One of these challenges is the fact that active-matrix OLED (AMOLED) panel manufacturing is still an inefficient process, Jakhanwal said. As the size of OLED displays becomes larger, the yields and manufacturing losses also get larger.

"As a result, AMOLED products are going to be small-sized displays, for applications such as mobile phones and personal media players (PMPs) for a few more years," Jakhanwal said. "OLED suppliers still are struggling with improving yield rates and low manufacturing efficiencies for small-sized displays."

Furthermore, OLED material lifetimes are still an issue for products that require long lifetimes such as televisions. Add to this the fact that AMOLED suppliers cannot guarantee high volumes because the technology is coming from a single source.

However, OLED TV has a number of great upsides, including: OLED TVs use no backlights, so they offer potential power-savings benefits compared to other technologies. Because they have no backlights and use only a single glass substrate, OLED TVs can be very thin.

The response time for OLED TVs is very fast, so there is no motion blur while watching television. OLED TVs have a much richer color gamut than competing display technologies.

iSuppli forecasts the global OLED TV market will reach 2.8 million units by 2013, managing a compound annual growth rate (CAGR) of 212.3% from just 3,000 units in 2007. In terms of global revenue, OLED TV will hit US$1.4 billion by 2013, increasing at a CAGR of 206.8% from US$2 million in 2007.

Potential is everything

Because OLEDs already serve as small panels for mobile handsets, PMPs and other small handheld devices, it is safe to assume OLED TVs could be a natural fit for automotive infotainment, mobile television, kitchen televisions or other consumer electronics devices that want to add small-screen sets.

The main challenge for the OLED TV industry is making large-enough panels that could be sold at reasonable prices in order to compete against the other television technologies.

Still, iSuppli believes that OLED TV is promising in the long term. Reducing power consumption, extending lifetimes, achieving larger sizes and attaining reasonable pricing eventually will help OLED TV to be competitive, but in the meantime, it will find a place in applications that require small sets.

It's so tiny, yet so expensive. I would buy a 27" for $1K, though.

I certainly will be following Sony's development of the OLED with interest. At least they have made a start. For now I will buy a Pioneer Plasma (Pro-150FD) ... but my next TV my well be a Sony OLED if they can advance to large screens (60") at a competitive price.

its not too bad, i was expecting sony to unveil technology around 10K for no reason.

"Other stunning performance indicators include a dramatic 1,000,000:1 contrast ratio and a low 45W power consumption."

It sounds like a great technology, but has Sony solved the lifespan problem? How long will these things last? If they last 20,000. hours or more, that's OK. If it is less, then few will want to pay those high prices, no matter how good the contrast is.

Myself, I would like a 110" OLED screen, and at some future date that may be possible.

Sony has quoted a lifetime of 30,000 hours for the unit. I think the ultimate goal is 50,000 hours for OLED TV's, but this is pretty good for a first gen product.

Is that for half-life? And at what brightness? Blues haven't reached the 30k hours at acceptable brightness yet so I would be very hesitant to accept this without having all of the information. Also, Active Matrix OLEDs will have the same "sample and hold" effect that LCD exhibit and based on the motion tests of 120hz LCDs, more work still needs to be done on this.

Will they? What kind of work? Image interpolation and scanning are separate techs. Look at those scanlines.

The 30,000 hours is the half-life for the luminance....overall brightness starts at 600 cd/m2.

45 watts for a 5" tall by 10" wide (11" diagonal) screen is not efficient at all. That comes to 45 watts for 50 square inches, which means .9 watts per square inch of screen. Just imagine a 73" diagonal OLED screen which will have 2,304 square inches. Multiply that by .9 watts and you have impossible power consumption.

Am I missing something?

Most of those watts go to image processing circuits and that 45W rating is peak consumption(full white screen) afaik.
post #259 of 9447
Yep. That 73 incher might only consume 60W.

Toshiba Corp. just announced plans to begin selling televisions with OLED screens as soon as panels are ready, according to a company spokeswoman. The first Toshiba OLED television sets should hit the market in 2009.
post #261 of 9447
Same meaningless line of production promises that Toshiba made frequently about when they would deliver SED to consumers. Fool me once; well you know how the rest of it goes!

I am going to start selling viable dinosaur eggs and time machines as soon as my DNA and space-time research in complete. Would you like to make a deposit for a pre-order?

I'll check back in 3-4 years. Hopefully Sony or one of their competitors will have a 60" version ready and it won't be "Ferrari" priced. My 60" XBR2 is great for PQ and CR but black levels are only decent.

bump.

As expected OLED response time has a long way to go yet.

CEATEC 2007 Highlights

"Viewing the set at CEATEC revealed a very high contrast image. Sony claims high motion resolution, however, based my viewing of Sony’s demo material on the XEL-1, the motion resolution was quite poor. One scene showed a yellow taxicab. When it was still, the writing on the cab’s door was very sharp, but once the taxi started moving, the image blurred considerably, to the point where the writing was totally illegible."

Implementation, implementation! The actual emitters run very fast, it's the driver circuit design which causes blurring.

Or it could even be the source material.

I started a thread on this in another forum, but nobody responded.

If you live in the San Antonio area, Bjorns is debuting their "room within a room" this weekend dedicated to Sony products. They'll have Sony reps on hand Friday, Saturday and Sunday to answer questions.

They'll also have an OLED TV on display.

If anyone goes, can you report back? Also, can you ask the reps about the Sony 70XBR5 (release date, weight, MSRP, etc.)?
