CMEL and CMO develop 25-inch AM OLED TV panel, geared to produce 2.0" & 3.0" AMOLEDs.

Chi Mei EL Corporation (CMEL) announced that it has successfully employed the latest low temperature poly-silicon thin film transistor (LTPS TFT) process technology from Chi Mei Optoelectronics (CMO) together with its own organic light-emitting diodes (OLED) equipment and technology to develop a full-function, full-color 25" OLED TV panel.

This 25" OLED panel is currently the world's largest LTPS AMOLED panel. This successful application of new technologies from CMEL and CMO showcases CMEL's mature product development capabilities and advanced OLED process technology, as well as CMO's unique LTPS TFT process technology.

The new 25" AMOLED TV panel uses the latest LTPS TFT production technology developed by CMO to avoid non-uniform images that plague conventional LTPS TFT panels. Excessive critical voltage fluctuations often cause non-uniform images in conventional LTPS TFT panels; this typically results in a low production yield and difficulty in increasing panel size. CMO's LTPS TFT panel technology -- which ensures outstanding performance and consistency -- can be used in OLED TV panels offering extreme thinness, an ultra-wide viewing angle, ultra-high contrast, and ultra-fast response time. CMEL has also developed passive matrix OLED (PMOLED) products as well as 2.0" and 3.5" active matrix full-color OLED panels using CMO's unique LTPS TFT technology. CMEL will exhibit its new products from Oct.18 to Oct. 20 at the FPD International 2006 in Yokohama, Japan.

The Optimus-113 keyboard will NOT use OLED displays

Art.Lebedev has launched a new blog about their Optimus Keyboard, and announced that the Optimus-113 keyboard will NOT use OLED displays after all.

"The price for the shipping unit remains withing range of a good mobile phone (but not $20,000 or $5,000 as some people may think after shopping for another Vertu).

And we had to make one very important decision during the engineering: we will not use OLED screens for the Optimus-113.

Another important thing: all keys will be replaceable."

Here comes the OLED

UDC OLED pen concept (2004)OLED is a new display technology that promises to deliver thin, power efficient and bright displays. OLEDs (already popular in MP3 players and cell phones) have amazing potential - thin TVs, flexible displays, transparent monitors, white-bulb replacement, and more.

An LCD works by having a backlight (white light) source, which is then filtered make colors. OLEDs however work by emitting color light. This has several advantages. It allows to make simpler and thus thinner and cheaper displays. It also means that OLEDs require less power. Think that when you have a screen that is completely black (but turned on), LCD will still require the whole white backlight to be emitted. With OLEDs, almost no energy is consumed in such a scenario. It is also possible to make flexible OLED displays, and even transparent ones, but this is obviously more challenging than a simple LCD-like display.

While OLEDs are heralded as the display technology of the future, they are already produced and used today. While making large panels is still a great challenge, smaller screens (up to 2") are already produced in commercial quantities today. There are many MP3 players and cellular phones that use OLED displays. Companies such as Sony and Samsung use OLED displays in their leading models. The OLED market reached 500$ million in sales in 2005, and is expected to grow quickly in the coming years.

There are two main types of OLED screens Passive Matrix (PMOLED) and Active Matrix (AMOLED). PMOLED displays are cheaper and easier to manufacture, but they have a limitation in resolution, size and refresh rate. Most OLEDs that are being made today are PMOLED. However several companies (including Samsung SDI and LG.Philips) have announced plans to begin producing AMOLED panels in 2007.

The future for large OLED panels is not so certain. The major limitation of OLED technology today is the lifetime, especially for the blue color. Progress is being made all the time, but the technology is not ready yet. Scaling the OLED screens is not an easy thing to do, either. Making a large panel (for TV or computer screen) is far from simple. While prototypes have been showed, it will take several years before we'll be able to buy an OLED television.

OLEDs actually make it possible to create screens that are flexible and/or transparent. The possibilities of this kind of displays are almost endless. Think about car windshield-embedded transparent displays, or rollable mobile TV. This technology is still at an early stage, but already companies are showing prototype and design sketches.

One of the areas that seem most promising for OLEDs is white lighting. Many companies are hoping that OLEDs will enable very efficient light sources. With today's high energy costs, and the drive for efficiency, there is a lot of money in white-light research, and OLEDs are seen as one of the best future technologies. OLEDs will also enable unimaginable designs, because of their thin and flexible nature.

Universal Display Awarded SBIR Phase II Grant from the U.S. DOE for White OLED

Universal Display Corporation today announced that it has been awarded a Small Business Innovation Research (SBIR) Phase II grant for $750,000 from the U.S. Department of Energy (DOE) to develop power-efficient WOLED™ white OLED technology for future solid-state lighting applications.

Through this Phase II program, Universal Display is seeking to demonstrate novel WOLED device designs that offer further enhancements in power efficiency and operating lifetime based on the Company’s proprietary PHOLED technology.  The DOE has developed a technology roadmap suggesting a feasible path for white OLEDs to achieve power efficiencies of 100 to 150 lumens per Watt (lm/W).  Universal Display’s PHOLED technology is a critical element for achieving this goal.  The Company recently announced a white PHOLED with a power efficiency of more than 30 lm/W and external quantum efficiency (EQE) of 29 % at 850 nits, which the Company believes is the highest EQE reported to date.  Through programs such as this one, Universal Display hopes to achieve continued performance gains toward the DOE’s roadmap goals.

The new program will also leverage the Company’s proprietary OVPD™ organic vapor phase deposition processing technology.  OVPD technology offers the potential to optimize organic layer thicknesses, doping concentrations and the interfaces between the layers, and also to provide excellent film uniformity over large areas.

New iSupply mobile display report, sees 160 million OLED displays by 2012

iSuppli Corp. forecasts mobile handset displays will reach 1.2 billion unit shipments in 2006, up 17 percent from 1.05 billion in 2005. Organic Light-Emitting Diode (OLED) main displays will represent a mere 1 percent of the main display market this year. By 2010, this mix will change, with TFT-LCDs representing 87 percent of the market, monochrome and color STN-LCDs comprising only 4 percent of shipments and 9 percent of the market being served by OLED main displays.

While TFT-LCDs will thrive in the mobile handset display market in the coming years, overall mobile OLED panel shipments will slowly climb to reach 47 million units shipped in 2006, up from 32 million units in 2005. The largest growth area for mobile-phone OLEDs will be in the main display market, where iSuppli forecasts shipments will grow to 160 million units by 2012, up from a mere 13.7 million units in 2006.

As AMOLED manufacturing becomes established, it will account for more than 20 percent of the OLED display units shipped by 2009 and about 40 percent of OLED display units shipped by 2012.
