DuPont Displays Opens OLED Materials Scale-Up Facility for Next Generation TVs

/0 コメント/カテゴリ: /作成者:

On 30 September (local time), DuPont Displays announced the opening of a state-of-the-art, scale-up manufacturing facility designed to deliver production scale quantities of advanced materials that enable large-format, solution-based printed OLED displays.

 

These materials are designed to help manufacturers develop OLED displays that are brighter, more vivid, longer lasting and significantly less expensive than the OLED TVs on the market today.  The facility is located at the DuPont Stine-Haskell Research Center (Stine-Haskell) in Newark, Del., near DuPont’s global headquarters in Wilmington, US.

 

DuPont’s new scale-up facility is sized to meet the future growth expectations of the OLED TV industry, which analysts predict will increase by over 70 percent for the next several years and will require large quantities of highly sophisticated OLED materials. This new OLED facility at Stine-Haskell has large-scale formulation systems and can support simultaneous production of multiple product lines.

 

“Materials are critical to the performance of an OLED TV and we are confident that DuPont has the best performing solution OLED materials available in the market today,” said Avi Avula, global business director, DuPont Displays.  “Our vision is that OLEDs will become the display standard and to make that vision a reality, we are focused on helping our customers bring the cost of large sized OLED TVs down to less than $1000 by 2020.”

Universal Display Corporation (Nasdaq:OLED), enabling energyefficient displays and lighting with its UniversalPHOLED® technology and materials, and LG Display Co., Ltd. (NYSE: LPL), the world’s leading innovator of display technologies, today announced the signing of a new OLED Technology License Agreement and Supplemental Material Purchase Agreement. The agreements run through December 31, 2022.
Today’s announcement builds on a long-term relationship between the two companies. Under the license agreement, Universal Display has granted LG Display non-exclusive license rights under various patents owned or controlled by Universal Display to manufacture and sell OLED display products. In consideration of the license grant, LG Display has agreed to pay Universal Display license fees and running royalties on its sales of these licensed products over the term of the agreement. Additionally, Universal Display will supply phosphorescent materials to LG Display for use in its licensed products.
“We are excited to enter into these agreements with our long-term partner LG Display, a global technology innovator who is leading the charge for OLED TVs, evidenced by its recent CES showcase of new 4K models ranging from 55″, 65″ and 77″ in flexible, curved and flat form actors,” said Steven V. Abramson, President and Chief Executive Officer of Universal Display Corporation. “The growth of our relationship demonstrates the continued acceptance of our OLED technology and phosphorescent materials by the display industry for cutting-edge, high performance, energy-efficient commercial OLED displays. We look forward to the continued collaboration in support of LGD’s advancements in expanding the thriving OLED product roadmap, including the advent of new form factors that redefine what a display can and will be.”
“This is a win-win partnership for both companies. We expect this strategic alliance with Universal Display will bring synergies in accelerating the growth of OLED technology, and based on strengthened OLED business, LG Display is committed to deliver differentiated products to customers and the market,” said Sang Deog Yeo, President and Head of OLED business unit of LG Display.

LG Display (CEO Sang-beom Han, 韓相範 / www.lgdisplay.com) and OLED materials firm Idemitsu Kosan (CEO 月岡隆, Takashi Tsukioka, hereinafter “Idemitsu”) entered into the agreement on the 11th about the ‘mutual cooperation concerning OLED technology and related patent license’ to further strengthen their competitiveness in the OLED industry.

 

In 1997, Idemitsu developed what was then the world’s brightest blue light organic emitting material for OLED and since then, every effort has been made to develop high-tech OLED materials and diverse device technologies based on its own molecular design and organic synthesis technologies. Consequently, Idemitsu Kosan, the original OLED material technology firm of a top global level possesses numerous major patents in relation to the OLED technology.

 

Through this strategic partnership, LG Display will be accessible to the excellent OLED materials and device structures of the Idemitsu Kosan which will lead to consolidate the research, product development and production of the OLED for TV and flexible OLED, and this eventually will accelerate the expansion of OLED market. By providing high performance OLED materials to the LG Display and collaborating in terms of technology development and commercialization, Idemitsu Kosan is expected to secure leading global clients in the display field.

 

The industry prospects that the two companies have made a chance to perform sound leadership by maximizing the synergy in the OLED business through this partnership.

 

Sang-deok Yeo, president of LG Display OLED Business unit said that, “Through the latest partnership, LG Display is to gain momentum to create OLED TV market on the basis of the OLED related patents of Idemitsu Kosan as well as accelerate the developments of flexible and transparent OLEDs” and added that “This win-win collaborative relationship is expected to have a huge synergy effect on OLED business for both companies.”

Yamagata University develops low-voltage blue phosphorescence material

According to a Japanese media, Nikkei, organic device engineering professor Junji Kido of Yamagata University has developed a low-voltage blue phosphorescent material. It is a material that can be driven with a low-voltage of 2.5V and its external quantum efficiency is high as 30%.

Yamagata University has published a paper on a new material on a science magazine, 『Advanced Materials』, issued on June 27th, 2014. The peak of this materials wavelength is 474nm (band gap is 2.62eV) and the reduction of quantum efficiency is small in high brightness zone. Also, the external quantum efficiency is 30% in 100cd/m2 and 20% efficiency can be maintained in high brightness of 10,000cd/m2.

Yamagata University actively develops TADF (Thermal Activation Delay Fluorescent) technology, which makes fluorescent material to realize the similar efficiency close to phosphorescent material, and white OLED using printing technology other than the blue phosphorescent material.
