Update: the new company was indeed established, but the name is Global OLED Technology

LG Group has decided to create a new company that will handle all OLED patents and technology. It will be financed by LG Electronics, LG Display and LG Chem. The company will be created soon (hopefully before the end of 2009), and will probably be called LG OLED.

LG 15-inch OLED TVs

The new company will acquire all of Kodak's OLED patents, and will manage license contracts owned by Kodak.

LG Display is producing OLED panels (currently small/medium ones, up to 15", and has plans to start making large-sized OLED TV soon). LG Electronics is already selling OLED phones, and also the 15" OLED TV in Korea. LG Chem are working towards OLED Lighting, with plans to start producing panels in 2010. 

LG Chem is the latest company to start working on OLED Lighting. LG Chem is showing 4 sizes of OLED Lighting panels, in the form of a Mondrian photo:

• 50x70 mm
• 150x20 mm
• 150x30 mm
• 150x150 mm

LG Chem's panels use green and red PHOLED materials made by Universal Display, and SFC's deep-blue fluorescent OLED (UDC and SFC are working together since 2008). The basic structure is Anode-Blue-Intermediate Layer (using LG 101 materials) Green&Red Cathode, and the panels provide various color temperature (this was achieved by changing the thickness of materials and the laminar structure).

 

The OLEDs on display were cold, full white OLEDs, with 20-25lm/W efficiency and a color temperature of 5000-6800K.

LG Chem's plan is to mass produce OLED Lighting products in 2H 2010 and is developing equipment together with Sunic System. LG Chem currently uses 200x200 deposition equipment and pre-process equipment.

Universal Display Corporation today announced that the company has successfully demonstrated a record-breaking white OLED with a power efficacy of 102 lumens per watt (lm/W) at 1000 cd/m2 using its proprietary, high-efficiency phosphorescent OLED technology.

Just last month at the Society for Information Display Symposium, Universal Display announced a new record of 72 lm/W. Since then, Universal Display has continued to make significant advances in this area achieving yet another major milestone toward commercialization. The milestone also demonstrates the potential of white OLEDs to offer significant energy savings and environmental benefits to end users around the world. For the first time, white OLEDs have surpassed the power efficacy of the two incumbent indoor lighting technologies - incandescent bulbs are less than 15 lm/W and most fluorescent lamps are 60 - 90 lm/W.

Funded in part by the U.S. Department of Energy (DOE) through its Solid-State Lighting initiative, Universal Display’s 102 lm/W milestone is a significant achievement toward the DOE's roadmap goal of a 150 lm/W commercial OLED light source by 2015.

This WOLED light source also offers a pleasing white emission with a color rendering index (CRI) of 70 and a coordinated color temperature (CCT) of 3900 Kelvin. This all-PHOLED structure uses complementary materials from Universal Display's collaboration partners at LG Chem and Nippon Steel Chemical Company.

Through the use of Universal Display’s PHOLED technology, power-efficient white OLEDs have the potential to reduce energy consumption dramatically and to lower the amount of by-product heat, which creates additional energy and environmental burdens. White OLEDs are also environmentally benign, especially compared to mercury-containing fluorescent lamps and newer compact fluorescent lamps (CFLs). It has been estimated that white OLEDs could worldwide save well over $20 billion in electric costs and over 9 million metric tonnes of carbon emissions from the U.S. alone by 2016.

UDC describes a new simplified WOLED architecture that represents an important milestone toward the achievement of cost-effective OLEDs for lighting applications. Offering a warm white color with CIE coordinates of (0.45, 0.46) and 30 lumens per Watt (with outcoupling), this WOLED device boasts an extremely long operating lifetime, exceeding 200,000 hours at 1,000 cd/m2, and may be suitable for a variety of entry lighting products.

Dr. D’Andrade will also report on a new white OLED with record-breaking power efficacy of 72 lumens per Watt. Both devices use transport and injection materials provided by Universal Display’s collaboration partner, LG Chem.

This work was funded, in part, by the U.S. Department of Energy (DOE) through its Small Business Innovation Research (SBIR) program. Under the SBIR program and the Solid State Lighting Initiative, the DOE is working to accelerate advances in OLEDs as an energy-efficient, solid-state lighting technology. The DOE views OLEDs as a pivotal emerging technology that promises to fundamentally alter lighting in the future. Through the use of Universal Display’s PHOLED technology, WOLEDs have the potential to meet the DOE’s future performance targets, including a power efficiency of 150 lumens per Watt, in an exciting new thin form factor.

LG Chem and Universal Display Corporation today announced that they have signed a non-exclusive joint development agreement to accelerate the commercialization of high-performance OLED materials for use in OLED displays and lighting products. The collaboration will focus on combining LG Chem's electron transport and hole injection materials with Universal Display's phosphorescent OLED emitter materials and technology.

Universal Display's proprietary PHOLED technology offers up to four times higher efficiency than conventional OLED technology - a feature that is very important for today's battery-operated cell phones and other portable devices, as well as for tomorrow's large-area TV's and solid-state lighting products.
