Universal Display Corporation
Universal Display Corporation (UDC) is a leader in developing and delivering organic light emitting diodes (OLED) technologies, materials and services to the display and lighting industries. It is also an OLED research company, and one of the field's pioneers. Founded in 1994, the company currently owns or has exclusive, co-exclusive or sole license rights with respect to more than 3,000 issued and pending patents worldwide for the commercialization of phosphorescent based OLEDs and also flexible, transparent and stacked OLEDs - for both display and lighting applications. Based in Ewing, New Jersey, with international offices in Ireland, South Korea, Hong Kong, Japan and Taiwan, Universal Display works and partners with a network of organizations, including Princeton University, the University of Southern California, the University of Michigan, and PPG Industries, Inc. Its phosphorescent OLED technologies and materials are licensed and supplied to companies such as Samsung, LG, AU Optronics CMEL, Pioneer, Panasonic Idemitsu OLED lighting and Konica Minolta. UDC is working with many other companies, including Sony, DuPont and Novaled. Back in 2009 UDC claimed that "virtually All AMOLEDs on the market use our technology".
OLEDs reportedly use less electricity, have better contrast and viewing angles than LCD or LED screens and can be made on flexible screens. OLED displays, it is claimed, have the following advantages over LCD displays:
- Lower power consumption
- Faster refresh rate and better contrast
- The screens are brighter, and have a fuller viewing angle
- Better durability - OLEDs are very durable and can operate in a broader temperature range
- Lighter weight - the screen can be made very thin, and can even be 'printed' on flexible surfaces
- Flexible and transparent displays 
OLED screens are growing in popularity and according to Display Bank global shipments reached 53 million units in Q2, 2013. Which is a 41% increase of the previous years shipments.
Universal Display's OLED screens currently feature in Samsung's flagship Galaxy S, S II and S III smartphones. The Galaxy S3 sold 10 million units in the first three months after its launch in April 2012. Also, their Galaxy Note has sold 10 million units since launch.
The Galaxy SIII was the company's fastest selling smartphone, selling 20 million units in 100 days. While the Galaxy S4 sold 10 million units in the first 30 days on the market, and 20 million in the first two months of sales. This is 70% faster than the Galaxy S3, which demonstrates the growing popularity of OLED screened smartphones.
Samsung's new flagship smartphone, the Galaxy S4, sports a 4.99" Full-HD (1920x1080, 441 PPI) Super AMOLED display behind a Corning Gorilla Glass 3.
Universal Display reported that Samsung Display Corporation (SDC) adopted UDC's green PHOLED (host and emitter) in the 5" Full-HD Super AMOLED dipslay used in the GS4 smartphone. This is a significant development as the green PHOLED increases energy efficiency of displays by up to 25%
In October 2013, Samsung released the first ever curved display smartphone called the Galaxy-Round. Samsung also introduced the "Roll Effect" where when the phone's screen is off and is rolled, it displays basic information like time or battery percentage. While it is possible to curve LCD screens, analysts say OLED screens provide better technical benefits.
In September 2013 Samsung unveiled their Galaxy Gear Smartwatch having an 1.6 inch OLED screen and multiple apps to link the watch to an Android smartphone. It will go on sale in the US for $299 and features a 1.63" 320x320 (275 PPI) Super AMOLED display, a 1.9 mp camera (can do 720p videos), 800Mhz processor, 4GB of storage, 512MB of RAM, Bluetooth 4, and a 315 mAh non-removable battery.
"Phablets" are defined as a device that has a screen between 5 and 7 inches and is part phone-part tablet. Examples include the Galaxy Note I, II and III. Samsung unveiled their Galaxy Note 3 at the IFA electronics show in September 2013. The Galaxy Note 3 has a 5.7 inch AMOLED screen. Display Mate tested the screen on the Galaxy Note 3 and say it is the best OLED screen they have tested and is superior to all LCD screens they have tested. They were quoted as saying: "The most notable advancement in this new panel is the high brightness. It can achieve 660 cd/m2 in high ambient light. It's not just 55% brighter than the Note 2, it's actually the brightest display ever tested at DisplayMate. A very notable achievement for Samsung's OLEDs, which were lagging behind LCDs in brightness."
"Trust me when I say that the Samsung Galaxy Note 3's screen is simply gorgeous. Measuring a vast 5.7 inches across, the AMOLED display has an ultracrisp full HD resolution (1,920x1,080 pixels) which translates into an amazingly sharp 385ppi. That's a level of detail that puts the smaller screens of the iPhone 5S (4-inch, 326ppi) and Samsung's own Galaxy S4 (5-inch, 441ppi) to shame." 
Samsung and LG-Display introduced their 55 inch OLED-Television devices at CES-2012. But both companies had to delay their mass production until 2013. Also AUO, Sony and Epson will start AMOLED-TV production in 2014.
In June 2013 Samsung announced the Korean availability of a 55-inch curved OLED HDTV. Priced at 15 million Korean won (around $13,500). Samsung also reiterates the claim LG made when it launched its own curved OLED model that "keeping all parts of the screen an equal distance from the viewer makes for a better viewing experience." By August 2013, Samsung dropped the price of the OLED television by 30% claiming "better yields" in manufacturing.
The Korea Times claims that Google's next gen Google Glass HMD (or "wearable computer") will use OLED microdisplays made by Samsung Display, with licensed technology from Universal Display.
OLED's enable screens to be made in curved or flexible format. Samsung's flexible AMOLEDs will be fabricated on a plastic (Polyimide) substrate and will be able to withstand high temperature (up to 350-400 degrees). The displays can be bendable - but since the first products will use them inside rigid glass cases - so it'll actually be "curved" displays and not flexible ones. A plastic based AMOLED will be shatterproof, and will also be lighter and thinner compared to glass based OLEDs.
OLED Info reports that for flexible displays on plastic, UDC's UniversalBarrier single-layer encapsulation technology is being evaluation by Samsung. UDC has a working 6" R&D deposition machine for the encapsulation layer. They go on to describe how Corning Glass have developed a flexible glass to help speed up the adoption of bendable OLED screens. "On Aug. 28 2013, Corning and AU Optronics announced that Corning is an important and strategic highperformance display glass collaborator for AUO’s line of AMOLED panels. AUO selected the Corning Lotus Glass platform based on the glass substrate’s outstanding thermal and dimensional stability. This aids AUO with efficient manufacturing during the high-temperature processes that are required to develop its AMOLED panels." Corning is also developing a Roll to Roll manufacturing process that will greatly reduce costs of mass-producing flexible displays.
UBI Research published a new report on Flexible OLED displays, forecasting a very fast growth: from 20 million units in 2012 to 150 million units in 2013. UBI sees $6.3 billion in flexible OLED revenues in 2017. This is far more optimistic than the recent report by Markets&Markets who see the entire flexible display market at $3.2 billion in 2017.
The Flexible Display Center announced that it has successfully manufactured the world’s largest flexible color AMOLED prototype using advanced mixed oxide thin film transistors (TFTs). Measuring 7.4 diagonal inches, the device was developed at the FDC in conjunction with Army Research Labs scientists. It also meets a critical target set by the U.S. Department of Defense to advance the development of full-color, full-motion video flexible OLED displays for use in thin, lightweight, bendable and highly rugged devices. “This is a significant manufacturing breakthrough for flexible display technology,” said Nick Colaneri, director of the FDC. “It provides a realistic path forward for the production of high performance, flexible, full color OLED displays, accelerating commercialization of the technology in the process." 
Universal Display's Sid Rosenblatt talking about the future of OLED technology was quoted as saying: "Samsung is going to introduce flexible screens, but the flexible plastic substrates are difficult to manufacture. Plastic is porous and oxygen with moisture causes OLEDs to degrade. [However]...These kind of displays are unbreakable, flexible on stainless steel foil. It would result in a thinner device because you don’t have the pieces of glass. It could conform around the sides, so you can show information on the sides. It would be lighter. So you can either make it smaller or thinner or you can make a larger battery so that it lasts longer. The challenges are encapsulation, so you need an encapsulation process. The temperature is too high to deposit them directly to the plastic, so they do is they literally deposit them on glass." Further SID Rosenblatt thinks that flexible OLEDs will be initially a niche market for the high end.
iSuppli, a market research firm, sees the flexible OLED display market growing significantly from 2013 to 2020. Their estimates are from a market value of $21 million in 2013 to $100 million in 2014 and reaching $12 billion by 2020. IHS says this will bring about "unprecedented change(s) in flat displays".
OLED's have distinct advantages in lighting too, providing low temperature, low energy use lighting panels that can be used anywhere, even in cars. OSRAM believes that the next technological development for car lighting is OLEDs. The major advantage is that they provide "completely new options for the design of light and luminaires". The cars of the future, according to Osram will have both LED and OLED lighting sources. OSRAM in 2011, built an OLED Lighting production line in Regensburg, Germany. The company invested 50 million euros (around $70 million) in the production facility and in research on OLED applications.
The German government launched a new €34 million (about $44 million) project called OLYMP ("Organic Light-emitting sYstems based on energy and cost-efficient Materials and Processes") that intends to improve "OLED lighting efficiency and lifetime".
in 2012, UDC reported two favorable patent decisions. The first one is from Japan, regarding two patents (JP781 and JP158) relating to UDC's L2MX technology. The patents were upheld as valid by the Japanese patent office. The second decision related to one of the OVJP patents in Korea. The Korean patent office issued a favorable decision which upheld the patent as valid. Some financial analysts have contended that Universal Display's patents are likely to be rescinded in November 2013 at the EPO Board of Appeal, however Oppenheimer analyst Andrew Uekwitz already chimed in to defend them, saying Asensio's latest article "contains nothing new or valuable" that wasn't already disclosed in its most recent quarterly report.
