A German company called NovaLED will be revealing what they’re calling a “fault-tolerant OLED” at Finetech Japan in May. The NovaLED OLED will apparently be resistant of electrical shorts and faults which have, in its short history, killed other OLEDs. The NovaLED OLED is intended for large area illumination or long maintenance cycle applications.
From the press release:
Dresden, Germany, 14th April 2009
Novaled AG, leading technology and material provider for a new generation of lighting and display products, will introduce a novel defect tolerant OLED structure at Finetech Japan in Tokyo from 15th to 17th April 2009.
Novaled’s Defect Tolerant OLEDs maintain the appearance of a homogeneously lighted-up surface even in the case of electrical shorts, thanks to the use of its proprietary electrode design. One OLED element consists of two comb-shaped interlocked electrodes, which give a uniform light emission. If a short in one of the stripes appears, the resistance of the stripe will limit the current flow and prevent a further rise of current and temperature, which would otherwise destroy the OLED.
“OLED devices based on the new Novaled structure are well suited for large area lighting or other lighting applications which require a long maintenance cycle”, says Gerd Guenther, VP Marketing and Sales of Novaled AG. ”We are looking forward to presenting an OLED-wall demonstrator at the Novaled booth illustrating the concept of the Novaled defect tolerant structure. The topic will be also discussed in the talk of Mr. Philipp Wellmann of Novaled at Lighting Japan.” Further demonstrators like the Victory OLED Lamp with Novaled PIN OLED® inside will be exhibited to introduce possible lighting applications.
In time for the Lighting & Finetech event Novaled is going to launch its web site in Japanese and Korean languages underlining the importance of the Asian markets.
OLEDs (organic light-emitting diode) are semiconductors made of thin organic material layers of only a few nanometers thickness. They emit light in a diffuse way to form an area light source. In a fast growing display market OLEDs are key part of a revolution: the dream of paper-thin, highly efficient displays with brilliant colors and great flexibility in design. OLEDs represent the future of a vast array of completely new lighting applications. By combining color with shape, organic LEDs will create a new way of decorating and personalizing personal surroundings with light. At the same time OLEDs offer the potential to become even more efficient than energy-saving bulbs.
Novaled AG is a world leading company in the OLED field specialized in high efficiency long lifetime OLED structures and an expert in synthetic and analytical chemistry. The company offers complete solutions to the organic electronic markets, commercializing its Novaled PIN OLED® technology along with its proprietary OLED materials. Novaled has developed long term partnerships with major OLED players worldwide. Based on more than 400 patents granted or pending, Novaled has a strong IP position in OLED technology, and was named No. 1 on a list of coming world market leaders by the German newspapers Handelsblatt and Wirtschaftswoche. Main investors are eCAPITAL, CrÃ©dit Agricole Private Equity, TechnoStart, TechFund and CDC Innovation.
