EU project aims to take flexible OLEDs from lab to fab
28 January 2013

Flex-o-Fab project will create a pilot-scale manufacturing chain for flexible OLEDs, and use it to develop reliable fabrication / production processes. Funded through the EU’s 7th Framework Programme, the project aims to strengthen Europe’s leading position in the lighting industry by making flexible OLEDs a commercial reality.

The Flex-o-Fab project will run for 36 months beginning October 1, 2012 and aims to take flexible OLEDs from lab to fab by developing reliable processes for manufacturing OLEDs on plastic foils. To do this, the project will set up a modular yet integrated pilot production line and associated manufacturing chain.

Global OLED Technology wins two key patent challenges in Europe
21 January 2013

Global OLED Technology has announced that at the end of 2012 the Opposition Division of the European Patent Office held that two of their patents were maintained as amended following oppositions by Merck KGaA of Germany. Particularly, the Office held that Merck's arguments did not prejudice the maintenance of the patents as amended.

The two patent covered technologies that enable high efficiency and long lifetime in OLEDs for both display and lighting applications.

  • EP1730249 - this patent teaches the use of certain anthracenes as non-emitting hosts in the light-emitting layers of OLED devices.
  • EP1828342 - this patent teaches the use of hole-transporting material adjacent to the phosphorescent light emitting layer.

Goverment expected to step in to end display feud between Samsung and LG Display
21 January 2013

According to a report by Korean Times the Korean Government is expected to take steps to negotiate a settlement between Samsung Display and LG Display over their ongoing patent dispute.

Samsung Display and LG Display have been involved in an ugly fight over patents related to both LCDs and OLED technologies, as the two companies fight for dominance of the global display market.

Samsung has argued in court that LG’s patents in these areas should be delisted. LG countered by seeking a sales ban on Samsung Electronics’ Galaxy line of smartphones and tablets, which it claims depend on the infringed LG patents.

LG Display claims that Samsung infringed on its in-house technology with its OLED screen for the new Galaxy Note 10.1 tablet, which was produced by Samsung Display.

Fraunhofer IAP commissions new manufacturing pilot line for organic semiconductor technologies
14 January 2013

Fraunhofer Institute for Applied Polymer Research (IAP) announces the commissioning and opening of a new manufacturing pilot line for organic semiconductor technologies. This enables organic light emitting diodes (OLEDs) and organic photovoltaic (OPV) can now be developed at Fraunhofer Institute for Applied Polymer Research IAP in Potsdam-Golm on a near-industrial scale. The new pilot line was designed and implemented by Fraunhofer IAP in cooperation with the plant manufacturer MBraun. The plant was officially opened during a two day trade event at the instituition.

Fraunhofer IAP’s pilot line for solution-based processes is located in a cleanroom and measures a lenght of 15 meters

Sony develops the world's first and largest 56-inch 4K OLED TV
14 January 2013

Sony Corp. (Sony) has announced that the company has developed the "world's first" first 4K (3840 x 2160) OLED (organic light-emitting diode) televisions. Sony demonstrated the 56-inch prototype at the recent held International Consumer Electronics Show (CES) in Las Vegas, Nevada. The OLED panel used in this prototype 4K OLED TV on display at the exhibition was jointly developed with AU Optronics Corp (AUO).

The world's first and largest* 56-inch OLED TV achieves 4K resolution by using the latest oxide semiconductor TFTs and Sony's own 'Super Top Emission' technologies.

LG begins rollout of eagerly anticipated OLED TV
31 December 2012

LG Electronics (LG) has announced that it will begin accepting pre-orders for its eagerly-awaited 55-inch class (54.6-inch diagonal) WRGB OLED (Organic Light Emitting Diode) TV (Model - 55EM9700) in South Korea this month with deliveries scheduled to begin next month (February 2013). LG is expected to announce over the next few weeks additional more markets where the LG OLED TV will be available. The announcement comes just days before the 2013 Consumer Electronics Show (CES), where an early version of the TV last year was awarded "Best of Show."

More than 1,400 LG retail stores in South Korea will begin accepting orders from consumers for KRW 11 million (approximately US $10,000) TVs starting Jan. 3 with delivery to commence the first week of February. As the first and only company to announce availability of the next-generation TV technology, LG is prepared to ramp up quickly to take the lead in the OLED segment that is expected to grow to 7.2 million units by 2016, according to DisplaySearch.

Key technical features

  • diagonal - 55-inch OLED TV
  • thickness - 4 mm (0.16 inches)
  • weight - < 10 kilograms (22 pounds)
  • colour pixel system - a white sub-pixel, and conventional red, blue, green
  • colour refiner - greater tonal enhancement, resulting in images that are more vibrant and natural
  • contrast ratio - maintains optimal contrast levels regardless of ambient brightness or viewing angle

Havis Kwon, President and CEO of LG's Home Entertainment Company, said, "We are extremely pleased to be able to make this announcement at the start of the new year because we believe that OLED will usher in a whole new era of home entertainment." Havis added, "Not since color TV was first introduced 60 years ago has there been a more transformational moment. When high definition TV was first introduced 15 years ago, the public's reaction was 'wow!' but when customers see our razor-thin OLED TV for the first time, they're left speechless. That's a clear indicator as any that OLED TV is much more than just an incremental improvement to current television technology."

Small and medium display AM-OLED penetration to more than double by 2015
31 December 2012

Active matrix OLED (AM-OLED) displays have been gradually challenging LCD technology in small and medium (9” and smaller) displays, as mobile phone manufacturers have increased adoption.

According to the latest release of NPD DisplaySearch Quarterly Small/Medium Shipment and Forecast Report, this has led to AM-OLED capturing 6% of the small/medium display market in 2012 and their share is forecast to more than double by 2015 to 13%.

Total OLED display shipments are expected to reach 191 million in 2012, accounting for an 8.4% share of the overall small/medium display category.
