Ron Mertens from OLED-Info.com recently had the opportunity to interview Janice Mahon, Universal Display's VP of technology commercialization.

Janice, could you give a small introduction about UDC, and about your PHOLED products?

Universal Display Corporation (NASDAQ: PANL) is a world leader in the development of innovative OLED technology for use in flat panel displays, lighting and other opto-electronics applications. Founded in 1994, Universal Display provides state-of-the-art OLED technology and services to OLED manufacturers to enhance their products' features and competitive advantage. We have developed proprietary OLED technologies and materials that should provide dramatically enhanced display performance at lower costs than today's liquid crystal displays.

Universal Display Corp. has signed agreements with the University of Michigan, Princeton University and the University of Southern California to continue sponsoring research in organic light emitting diode (OLED) technology. Universal Display (Ewing, N.J.) will provide up to $4.6 million in funding to sponsoring organic electronics under the direction of Professors Stephen R. Forrest and Mark E. Thompson at their respective institutions over the next three years.

The company has already funded over $7.5 million in sponsored research at Princeton University and the University of Southern California since 1994.

The Georgia Institute of Technology's Center for Organic Photonics and Electronics (COPE) and Solvay announced a $3 million deal for OLED research today.

Solvay, an international chemical and pharmaceutical group headquartered in Brussels, Belgium, with units in more than 50 countries and a strong presence in Georgia, has signed a three-year commitment with Georgia Tech to fund research in organic light-emitting diodes (OLEDs).

DuPont announced a significant technology breakthrough in its OLED technology, taking a significant step toward commercialization of this next generation flat panel display offering. Using advanced materials, OLEDs produce low power, thin, high-performance flat panel displays. OLED panels are emissive, eliminating the need for backlights and simplifying display design compared to other display technologies, such as liquid crystal displays (LCDs).

DuPont has achieved lifetimes of the three primary colors each exceeding 10,000 hours of white lifetime (or 40,000 hours for a typical video) at the brightnesses required for a 200 nit display. With this development, DuPont has demonstrated that OLEDs can be manufactured at high yields and low total cost.

eMagin Corporation today announced the first four product offerings of its breakthrough OLED-XL(TM) microdisplay portfolio. eMagin's proprietary OLED-XL displays provide a new level of high performance imaging, with up to 410,000 hours luminance life, the widest temperature range, and the lowest power requirement of any commercially available SVGA resolution microdisplay system.

AlkaMax, an advanced alkali metal dispenser for mass production of Organic Light Emitting Diode (OLED) displays that eases the manufacture and increases OLED performance in terms of operating voltage and luminosity.

SAES Getters DryFlex proves to be the accomplished technology that boosts OLED display duration to over 30%, as demonstrated by a main OLED manufacturer in its tests.

SAES Getters’ AlkaMax offers the unique opportunity of using a safe and stable source to create a pure alkali metal single layer or an Alkali Metal Doped Organic Layer (AMDOL) instead of LiF or Li2O or any other electron injection stratum. These benefits are acknowledged by research groups of professor Kido at Yamagata University and of professor Adachi at the Chitose Institute of Science & Technology in Hokkaido1, that used AlkaMax in their tests and experiments. The use of pure alkali metal layer can overcome the needs of a strict control of the composition and thickness of the layer: through AlkaMax, a thin layer of metallic Cesium (Cs) or of another alkali metal can be easily and reliably created, exploiting all of the advantages of a low work function metal.

SAES Getters’ DryFlex is the thinnest dryer solution available for OLEDs, delivering the best trade-off between high sorption speed and reduced product thickness and it can be fully customized in shape and size to accommodate any display geometry.

Advanced Analogic Technologies Incorporated, a developer of power management semiconductors for mobile consumer electronic devices, today announced the AAT1230, a new 2MHz, 18V, 100mA step-up converter optimized for powering both Organic LED (OLEDs) and general purpose LCD and CCD modules in portable systems.

Using an advanced architecture developed by AnalogicTech, the AAT1230 delivers fast transient response, high stability, and excellent load isolation while dramatically reducing system footprint.

TI introduced today two new high-efficiency, dual-output DC/DC boost converters that can manage two sets of six white light emitting diodes - all from a single integrated circuit plus inductor. The devices feature an input voltage of 3 V to 6 V and can deliver up to 0.7 A of output current, making them well suited to drive organic LED (OLED) sub-displays and white LED backlighting for the liquid crystal display (LCD) main display in today's clamshell phones.

Novaled and Ciba Specialty Chemicals announce an industrial collaboration in the field of OLED materials. Ciba Specialty Chemicals will produce the unique organic dopant and transport materials developed by Novaled.

The unique organic dopant and transport materials for its proprietary OLED technology Novaled PIN OLED(TM) allow OLED devices to perform with the highest power efficiency. While Ciba Specialty Chemicals will produce these materials using its specific know how in the synthesis of organic materials in reliable highest purity, Novaled will continue to market the materials. The two companies will also collaborate in the development of future OLED products and platforms based on the Novaled's technology and materials.

Scientists in the US have devised a new flexible material that could revolutionise the way we light our homes and offices.

The material is the product of a 13 year research project by scientists at the USC College of Letters, Arts and Sciences, and the University of Michigan. It is similar to an OLED in that it uses layers of blue, green and red screens to create white light.

The new material replaces the blue screen with a dyed sheet, which cuts power consumption by 20 per cent but still allows the panel to remain clear when not supplied with current. This would allow the panels to be used as sky-light by day or as the transparent top to a laptop.
