Research and Markets: Application Range Sets to Widen as OLEDs Demonstrate Advantages over LCDs

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.

New Transparent White OLED from OSRAM Opto Semiconductors Achieves High Level of Performance

OSRAM Opto Semiconductors has developed a transparent white OLED tile with outstanding performance. Under laboratory conditions, the OLED prototype has achieved a luminous efficiency of more than 20 lm/W at a brightness of 1000 cd/m². This opens up possible applications such as partitions that are almost invisible by day and can provide a pleasant diffused light at night.

The large-scale prototype of the transparent white OLED tile with color coordinates 0.396/0.404 (CIEx/y main emissive side) lights up an area of nearly 90 cm². The OLED is transparent whether it is powered on or off, and its transparency is currently rated at 55%. As the product is further developed, this value is expected to reach 75%.

The performance results were achieved as part of the project known as OPAL 2008. This research effort is the initiative of the Germany Ministry for Education and Research dedicated to studying organic light emitting diodes for illumination applications.

The relative strengths of the beams in the two hemispheres of the OLED tile can be adjusted within a wide range. This means, for example, that a surface light source installed in furniture or on a canopy can be configured so that light shines only in the required direction.

Idemitsu Kosan and Universal Display Corporation today announced that they have signed an agreement to extend their collaboration to accelerate the development of phosphorescent OLED materials for use in displays fabricated through dry processing methods, such as vacuum thermal evaporation. The agreement expands the collaboration into red and green phosphorescent OLED materials, in addition to the blue materials that the two companies have been collaborating to develop since December, 2006.

In order to further expand the market for phosphorescent OLED devices, blue phosphorescent OLED materials need to be more fully developed and the quality and lifetime of red and green phosphorescent OLED materials should continue to improve. Therefore, Idemitsu Kosan and Universal Display have agreed to extend their collaboration into red and green phosphorescent OLED materials, in addition to continuing their work together on blue phosphorescent OLED materials. The collaboration is focused on matching Universal Displays phosphorescent emitters with Idemitsu Kosans phosphorescent hosts and other OLED materials. Through this collaboration, both companies expect to improve efficiency and operational lifetime of their respective phosphorescent OLED materials, which in turn should help accelerate the spread of phosphorescent OLED displays and lighting products.

Idemitsu Kosan has been developing OLED materials for middle and large size panels jointly with Sony Corporation (Sony) since 2005, and Universal Display also has been working with Sony since 2001. Idemitsu Kosan and Universal Display expect the results of this collaboration to be utilized for the OLED material development for Sony products.

iSupply: Is There Room for OLED Technology in the Television Market?

After examining Sony Corp.’s 11-inch Organic Light Emitting Diode (OLED) television exhibited here at iSuppli Corp.’s Flat Information Displays (FID) 2007 conference last week, there is no denying how stunning the picture is. But at just 11-inches, it’s hard to imagine a family gathering around it to watch a DVD or television show.



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 Liquid Crystal Display (LCD) or Plasma Display Panel (PDP) televisions at this time. However, this begs the question: Will OLED TV ever be able to match up with LCD and PDP televisions?



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 Corp., 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 $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 Corp. and Panasonic Corp. 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 percent from just 3,000 units in 2007. In terms of global revenue, OLED TV will hit $1.4 billion by 2013, increasing at a CAGR of 206.8 percent from $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.
