Sony has given an interesting presentation at SID. It seems like that the power efficiency depends on the TV program. In most programs OLED fares better than LCDs. (see the slide photo to the right)

Yoshito Shiraishi, general manager of E-Products and Business Development Department, TV Business Group, Sony, highlighted the superiority of OLED, saying, "OLED has many advantages over LCD."

According to digitimes, Sony is still on track to invest 210M$ in their OLED production of medium to large size panels.

The company will expand its capacity at Sony Mobile Display, enabling the plant to turn out even larger size OLED panels in fiscal 2009 (April 2009-March 2010).

Konica Minolta plans to launch the OLED lighting equipment by early 2011, Senior Executive Officer Shoei Yamana told the Reuters Global Technology, Media and Telecoms Summit in Tokyo.

There's a new OLED group that has just been formed - the OLED Association (OLED-A). The group is managed by Barry Young (Former senior VP, Display Search).

There are ten members in the group - Cambridge Display/Sumitomo, Corning, DuPont, Kodak, eMagin, Ignis, MicroEmissive Displays, Novaled, OLED-T, Samsung SDI, and Universal Display, and OLED-A are working to add more members.

eMagin Corporation is showcasing the latest innovations in power-efficient OLED microdisplays at this year's Society for Information Display Conference. eMagin is also showcasing its microdisplay portfolio and subsystems in rugged commercial products and modules which meet the needs of near-eye applications ranging from PC gaming to night-vision headsets and scopes to mobile command and control communications and training and simulation.

"Our growing portfolio of OLED microdisplays deliver high resolution, flicker-free images which work effectively in adverse conditions such as extreme temperatures and high-vibration conditions with extremely high power efficiency," noted Susan Jones, executive vice president and chief business/strategy officer, eMagin Corporation. "Our new cell architecture and OLED-XL technology provide the cornerstone for even more advanced microdisplay products."

Products featured at eMagin’s booth include:

SVGA+ Rev3 OLED-XL microdisplay, the most power efficient OLED solution for near-eye personal viewer applications. The SVGA+ Rev3 display uses less than 115 mW power in monochrome, such as for thermal imaging applications, and lower than 175 mW at 400 cd/m2 for full color video. This new microdisplay has simpler calibration over temperature and is ideal for demanding binocular luminance and color matching. It also shares all the functional and design characteristics of eMagin’s original SVGA OLEDs, already proven in military and first-responder systems, responding instantly at temperatures as low as -40 degrees C.

SXGA OLED microdisplay, the best combination of high resolution and low power requirement. eMagin is previewing features of its SXGA (1280 x 1020 pixels) microdisplay. The next generation SXGA OLED microdisplay, targeted for introduction next quarter, offers both analog and digital signal processing in a compact package (0.77-inch diagonal active area) requiring less than 200 mW under typical operating conditions of 400 cd/m2, full-color. Design enhancements include increased pixel uniformity, improved color gamut, on-chip temperature sensor and compensation, and compatibility with both analog RGB and digital video signals. This high-density OLED-on-silicon microdisplay promises an affordable, easy-to-integrate solution for many virtual imaging systems.

Universal Display Corporation today announced the development of the world’s thinnest flexible, active-matrix OLED (AMOLED) display prototype built to date. Resulting from Universal Display’s collaboration with Professor Jin Jang of Kyung Hee University, the Company’s research demonstrates significant flexibility enhancements and AMOLED robustness when built on ultra-thin metallic foil substrates. This work will be reported in a joint paper at the Society for Information Display (SID) 2008 International Symposium, Seminar and Exhibition at the Los Angeles Convention Center in Los Angeles, CA.

The joint paper, which will be presented by Universal Display’s Dr. Rui Qing (Ray) Ma, Department Manager, Flexible Displays, discusses the successful fabrication of a low-power flexible AMOLED device built on ultra-thin (25µm) metallic foil substrate. The monochrome device combines an amorphous-Silicon (a-Si) backplane developed and fabricated by Professor Jang’s team with a top-emission, phosphorescent OLED front plane from Universal Display. Through flexibility testing, the work shows that these backplanes can operate effectively when conformed repetitively to a tight diameter of 5 millimeters. This is significant in that it demonstrates additional feasibility for product concepts such as the Company’s Universal Communication Device™. Dr. Ma will present the findings today during the OLED Display Technology I session in Concourse Hall 152 at 10:40 A.M. PT. The paper is titled Highly Flexible Low Power Consumption AMOLED Displays on Ultra-Thin Stainless Steel Substrates.

We’re excited to announce advances in the flexibility and ruggedness of ultra-thin OLED displays, the result of a successful collaboration with our world-class collaborators at Kyung Hee University, said Steven V. Abramson, President and Chief Executive Officer of Universal Display. These advances support our initiative to develop flexible OLED display technologies for military and consumer applications, including a ‘roll-out’ OLED display for our concept Universal Communication Device.

Universal Display Corporation will today report advances in the development of P2OLED™, printable, phosphorescent OLED, material systems for use with ink-jet printing processes at the Society for Information Display’s (SID) 2008.

Presenting on a joint paper with Seiko Epson Corporation, Dr. Sean Xia, Senior Research Scientist at Universal Display, will describe advances in red, green and blue P2OLED material systems. Dr. Xia will also discuss the companies’ demonstration of ink-jet printed P2OLED technology and their continuing work to achieve commercial entry performance goals. Ink-jet printing has the potential to be a cost-effective approach for the production of large-area OLED displays.

The collaborative paper is the result of a joint development program during which the two companies successfully demonstrated the compatibility of Universal Display’s P2OLED technology and materials with Epson’s proprietary ink-jet printing process technology.

Through continued development using spin-coating techniques, the team has doubled the projected operating lifetime of its red P2OLED system since late last year to 100,000 hours (from an initial luminance of 500 cd/m2) with CIE coordinates of (0.67, 0.33) and a luminous efficiency of 12 candelas per Ampere (cd/A). The team also improved the projected lifetime of its green P2OLED system with CIE(0.33, 0.62) and a luminous efficiency of 34 cd/A to 63,000 hours (from an initial luminance of 1,000 cd/m2).

The team also made progress in the development of two blue P2OLED systems. A light blue P2OLED system with CIE(0.18, 0.39) and a luminous efficiency of 19 cd/A now has a projected lifetime of 6,000 hours from an initial luminance of 500 cd/m2, also twice that reported late last year. A new blue P2OLED system has more saturated color, with CIE(0.15, 0.22), a luminous efficiency of 6 cd/A and a projected lifetime of 1,000 hours (from an initial luminance of 500 cd/m2).

Universal Display’s PHOLED technology and materials, which offer up to four times higher energy efficiency than traditional OLED systems, are today being incorporated in products manufactured using conventional vacuum thermal evaporation (VTE) equipment. Universal Display’s P2OLED materials and technology are based on this same PHOLED technology, but are designed for use with solution-based manufacturing processes such as ink-jet printing.

LG Display showed a 15" XGA a-Si AMOLED for OLED TVs. The TV claims a 10,000:1 contrast ratio. This is very low compared to the Sony XEL-1 which boasts a 1,000,000:1 contrast ratio, although usually contrast measurements are rather sketchy.

LG also showed a 4" qVGA flexible AMOLED display on metal foil with increased flexibility and durability.

Universal Display Corporation and LG Display announced today the joint development of a flexible, full-color, active-matrix OLED (AMOLED) display prototype. Built on thin metallic foil, these prototypes are being showcased at each company’s booth during the 2008 Society for Information Display Conference.

The four-inch diagonal, QVGA full-color AMOLED display prototype combines LGD’s amorphous-Silicon backplane technologies with Universal Display’s OLED frontplane technologies, including its high-efficiency Universal PHOLED™ and transparent compound-cathode TOLED® technologies. Building on the foundation of the jointly-developed prototype shown at last year’s SID Exhibition, this new demonstrator offers enhanced brightness, improved color saturation, broader color gamut and a one-sided electrical interconnection, making it the most advanced flexible OLED display built on metallic foil using a-Si backplane technology to date.

The development of this prototype has been, in part, supported by the U.S. Department of Defense through the Battle Command Interface Branch of the U.S. Army Communication Electronics Research and Development Engineering Center (CERDEC). This work also complements flexible display development ongoing at the U.S. Army’s Flexible Display Center at Arizona State University, of which Universal Display is a founding member and LGD recently joined as an Associate member.
