GTT Announces Availability of Patent Portfolio Dealing with OLED Illumination

Global Technology Transfer Group, Inc., (GTT), a leader in patent asset management services, has announced the availability of a patent portfolio dealing with improved OLED illumination stability and improvements to AMEL technology. This portfolio is entitled 'Display Technologies Patent Portfolio' and consists of six US patents, one that relates to OLED technology and five that relate to AMEL technology.

The OLED patent relates to an improved passive matrix OLED device that provides for a control mechanism to maintain uniform light output from individual pixel elements throughout the illumination period. The invention additionally claims a passive matrix OLED device that provides for a control mechanism that prevents overshoot and undershoot illumination.

OLEDs have found a common place in small-screen devices such as cell phones, PDAs, and digital cameras. The first OLED product was a Pioneer car radio offered in limited production in Japan in 1997. Kodak was the first to release a digital camera with an OLED display in March of 2003. Sony soon followed in 2004 with personal-entertainment handhelds containing OLED displays. Sony followed this up in 2007 by releasing in Japan the first OLED TV. Research firm NanoMarkets released predictions for high commercial growth in the OLED market. Their predictions maintained the OLED market would hit $10.9 billion by 2012 and $15.5 billion two years later. While these predictions include active matrix OLEDs (AMOLEDs), NanoMarkets predicts OLED-based lighting to exceed $1 billion and the market for OLED displays in mobile phones and handhelds to rise to $7.2 billion by 2014, (both market areas in which PMOLEDs have seen success). Although OLED technology is still developing there is currently a notable market presence of OLEDs. GTT has analyzed the patent portfolio and prepared a detailed marketing report highlighting the technology and potential. For access to this information, please contact GTT.

The five AMEL patents also represent significant and important improvements to AMEL technology. The inventions described in the patents improve the color output, limit the voltage power required, and reduce manufacturing yields in AMEL devices.

"OLED technology, with its thin format, is highly sought after in the competitive markets of television, mobile phones and various other display and lighting application areas. Illumination stability is a key requirement for OLED market participants," explained Michael Lubitz, CEO & Chairman of GTT. "We are honored to be involved in the placement of this portfolio."
