LG.Philips LCD has announced that it will debut what it claims is the world's highest resolution 14.3-inch flexible color E-paper display at CES 2008.

The 14.3-inch E-paper display, which is equivalent in size to an A4 sheet of paper, represents a significant improvement over its predecessors with a resolution of 1280 x 800 pixels, and the ability to display 16.7 million colors, making it suitable for use in high-end multimedia applications. These displays are extremely energy efficient, only using power when the image changes. Additionally, the displays are extremely thin, at less than 300 micrometers.

Research and Markets has announced the addition of Opportunity Analysis in the OLED Markets to their offering.

With their advanced technology, improved energy efficiency, and superior viewing angle, OLEDs are identified as the technology of the future. While also a formidable technology, the LCD market will face gradual saturation, which will positively influence the demand for OLEDs. "OLEDs promise to be one of the key technologies of the future, particularly with respect to display and lighting applications," notes the analyst of this research. "The absence of the back light in OLEDs makes them much lighter and extremely thin compared to LCDs, which tend to be large due to the presence of back lights." The key advantage of OLED displays is that they are based on an emissive technology. Besides, the absence of back light units gives OLEDs certain advantages over LCDs. Reduced power consumption also makes OLEDs superior to LCDs, as the latter require more power due to the back light of the display module. Being emissive in nature, OLEDs offer significant power-saving capabilities, reducing long-term application costs.

Over the last few years, applications of OLEDs have increased in cell phones, camera, and MP3 players. As the technology advances and larger size panels get manufactured, they will have tremendous potential in a range of applications including thin TVs, flexible displays, transparent monitors, and white-bulb replacements. They are also expected to increase in the medical equipment market, automotive utilities, lighting equipment, casinos, and other industrial usages. Moreover, in the consumer electronics market, the emergence of 27-inch and 11-inch range OLED televisions is anticipated. These factors are increasing the demand for OLED panels.

Carving out Niche Market and Co-existence with LCDs Necessary Strategies for Long-term Success of OLEDs

Experts anticipate that the OLED market revenues will reach the billion-dollar mark by 2009. However, this might be a premature calculation and the market might require a few more years to touch $1 billion. Constant price reductions in LCD technology will make the OLED market a niche one. In the long term, the OLED market will grow at a faster rate due to the low competency level of thin film transistor (TFT) plants.

OLEDs will face strong competition from LCDs. Although the performance benefits of OLEDs surpass LCDs, the decreasing cost of LCDs and enhancement in LCD technology is key factor constraining the industry. The best strategy to overcome this will be the development of applications where OLEDs and LCDs can coexist, for example, in the backlight of an LCD panel. "OLEDs can carve out a market niche since LCDs have greater mass appeal due to their lower price," states the analyst of this research. "With declining prices, OLEDs might compete strongly with LCD technology in the future, but, at present, LCDs have better market presence and penetration rate even though OLEDs offer superior technology." To establish a significant market presence, OLED manufacturers should build on energy efficiency, improve resolutions, and boost OLED life cycles. Over time, OLED technology is projected to make a major impact on the overall electronics industry.

Ceelite is working on large white-light flexible displays. "CeeLites" are just 1/8" thick and use up just 4 watts of power per square foot, but can be made into banners 12 feet long and 30 inches high. Rather than OLEDs, they use light-emitting capacitors that emit electricity into a phosphorescent substrate. They won't be made into high-def TVs anytime soon, but they can be contained in simple plastic, which makes them more easy to bring to market than OLEDs.

With a power efficiency of 45 lumens/Watt (lm/W) demonstrated to date and the possibility of achieving up to 150 lm/W with additional development in the future, white phosphorescent OLED lighting has the potential to lead to significant energy savings and additional environmental or ‘green’ benefits. Additionally, the very thin and transparent form factor of this new lighting concept offers numerous design advantages that may enable a variety of novel uses as compared to existing incandescent and fluorescent lighting products.

Energy efficient technologies and ‘green’ solutions for every day use have gained prominence as fiscal concerns have joined with environmental ones, said Mr. Rosenblatt. Developed, in part, for the U.S. Department of Energy Solid State Lighting initiative, this transparent white OLED lighting panel combines our energy-efficient PHOLED phosphorescent and TOLED transparent OLED technologies into a very exciting lighting concept with a thin and light form factor. Amongst the many new prospective applications, one can imagine that these panels may someday replace standard office windows to provide lighting when day-lighting is insufficient.

Enabled by the Company’s high-efficiency PHOLED technology, which offers up to a 4:1 power advantage over existing fluorescent OLED technology, white OLEDs are seen by the DOE as a leading candidate for next-generation lighting. Universal Display is currently engaged in contract research with the DOE to work in a number of key performance areas for OLED lighting. Under this specific program, lead by Dr. Brian D’Andrade, the Company demonstrated an efficient white OLED with the added feature of being transparent when turned off.

In November 2007 Sony has started to sell their 11" OLED TV (the XEL-1). This is an exciting move by Sony, but this cannot be considered a real commercial OLED TV. They are only producing 2,000 of those units monthly, the price is extremely high - around 1,800$ for a 11" TV (and Sony admits they are losing money on each unit). Even the power consumption of those TVs is rather high - higher than compatible LCDs.

But still Sony is clearly committed to OLEDs - and it seems like they are betting the future of their TV business on OLEDs. Sony were late to the Flat-Panel TV "party" and are no longer considered innovators. Now they are trying to be in the forefront of the technology again, and OLEDs is their technology of choice.

The Australian government is proposing regulations that would ban most plasma and LCD HDTVs by the year 2011.

After commissioning a report that found the popularity of high power-drawing TVs like plasma and LCD TVs is growing. The bigger and brighter screens get, the more power is required, and Australia is trying to crack down on energy consumption. This is the government that was looking into banning incandescent bulbs in favor of fluorescent bulbs earlier this year.

By 2011, plasma and LCD TVs could be replaced with less energy consuming technologies like SED TV and OLED TV. But for now, the planet heats up because of our TVs.

Samsung Electronics announced today that it is mass producing a 16M-color display driver IC (DDI) for AMOLED displays used in mobile phones and other handheld devices. With outstanding image quality, AMOLEDs are attracting attention from device designers as the next generation display technology of choice.

Samsung's new mobile DDI for AMOLED displays support qVGA resolutions (240x320) and is capable of producing a range of over sixteen million colors. It is well in step with the recent expansion of multimedia functions and services offered in mobile devices. Samsung's new 16M-color DDI self-adjusts the screen brightness, illuminating only those areas that need light. As a result, power consumption is minimized and battery life extended. The read-only memory (ROM) is built in separately, enabling red, blue and green (RBG) gamma compensation to reproduce more lifelike images.

The new 16M-color AMOLED DDI is currently in mass production and has been introduced in Samsung SDI's AMOLED panels. Samsung's broad line up of DDIs for LCDs, PDPs and AMOLED displays addresses the diverse needs of its customer base.

NanoMarkets has published a new white paper that discusses the market opportunities for OLED lighting. The paper was drawn from a report released in Q3 of 2007. NanoMarkets discusses the status of current OLED lighting research, the competition, and also "Open Questions, Challenges and Solutions".

This analysis makes the case for printed and organic lighting market/OLED lighting seem very easy to make. But as always the devil is in the details. OLED lighting may be able to offer remarkable things such as substrate flexibility, but no one yet knows where that capability can generate the most revenues. Among the many new products that could be created using cool new OLED lighting technology we don’t know yet which are likely to be snapped up by customers. And while the potential for using R2R processes and printing opens up exciting possibilities for price points that would greatly accelerate the adoption of OLED lighting, nobody has yet settled on which manufacturing processes or materials make the most sense and which can promote the greatest leaps forward in terms of brightness, power efficiency, stability and lifetime.

The state of the art for OLED lamps today is roughly in the 1030 lm/W range today, but that’s likely to be a short-term frontier. UDC, for example, is in the midst of a 40 lm/W project and Eastman Kodak is working on broad enhancements to small molecule OLEDs under a U.S. Department of Energy (DOE) program culminating in September, 2008, with hopes of hitting 50 lm/W. Another DOE project is applying a novel nanocomposite coating material to the OLED anode to optimize hole transport and attain 60-80 lm/W in conjunction with a life exceeding 10 Khrs. The DOE’s technology roadmap 100 to 150 lumens/W for OLED lighting in the long run.

Universal Display Corporation today announced that it has been awarded a $750,000 Small Business Innovation Research (SBIR) Phase II grant from the U.S. Department of Energy (DOE) under the DOE’s solid-state lighting program.

Work under Phase II of the SBIR grant will focus on the demonstration of a simpler white OLED design that should reduce manufacturing costs, without compromising performance. This program is based on Universal Display’s proprietary PHOLED technology and materials - keys to achieving the energy efficiency targets for white lighting.

The new white OLED design will use two PHOLED emitters that will be specially designed to emit broadly so that the color spectrum can be optimally covered. The device is targeted to have a high color rendering index (CRI), an important metric for lighting applications, as well as excellent power efficiency.
