The US Department of Energy (DoE) has selected eight solid-state lighting (SSL) research and product development projects that will receive total funding of $13.3 million.
Samsung SDI aims to boost the monthly capacity of AM OLED panels to 4.5 million units in the third quarter of 2008, up from 1.5 million in the second half of 2007. Samsung SDI said the major applications for AM OLED panels in 2007 will remain for small-size displays such as for mobile phones and digital music players. The maker aims to provide 2.2- to 2.6-inch AM OLED panels initially and move to provide 3- to 4-inch displays for applications such as digital still cameras (DSCs) and PDAs, the company said. In 2009, Samsung SDI will start developing 5-inch-and-above AM OLED panels, the maker added.
Universal Display Corporation today announced the pricing of an offering of 2.8 million shares of its common stock at a price of $14.50 per share. The offering is being conducted pursuant to Universal Display's effective shelf registration statement. The offering is expected to close on May 22, 2007. Universal Display plans to use the net proceeds for working capital and general corporate purposes, including funding for research and development efforts, acceleration of the development efforts, investments and acquisitions relating to complementary businesses, technologies and intellectual property, and prosecution and defense of intellectual property rights.
LG.Philips LCD has announced that it has developed (in cooperation with UDC.) the first full-color flexible AMOLED display that uses amorphous silicon (a-Si) technology.
The 4-inch full-color flexible AM OLED display features 320Ã240 QVGA resolution and can reproduce 16.77 million colors. It uses a stainless metal foil substrate to ensure durability and protection against heat, which improves the manufacturing process and enhances product stability, noted LG.Philips LCD.
Using a-Si backplane technology allows LG.Philips LCD to use its existing TFT LCD production line for these AM OLEDs, a major step toward demonstrating the commercial viability of such products. LG.Philips LCD will unveil the full-color flexible AM OLED display at SID 2007 in the US on May 20.
Intersil Corporation today announces the release of the ISL97701. By combining high current output, an integrated Schottky diode and fault protection, Intersil provides the industry's most complete boost regulation solution for passive matrix OLEDs. With efficiency up to 87%, the ISL97701 can deliver 50mA of output current at 18V. It can provide up to 28V output, enabling power efficient operations in MP3, portable media players, automotive clustering, and low-end cell phones PMOLED displays. ISL97701 is also suitable for standard boost regulation applications such as WiMax card and LCD bias generator power applications.
The integration of the Schottky diode reduces the BOM cost and saves board space, while an integrated input disconnect switch protects the device against overcurrent, overvoltage and over temperature. The ISL97701 is highly versatile with a variable output that can be set by external resistors to match the needs of the application. At just 3mm x 3mm x 0.9mm, its 10-lead DFN (Pb free) package is a very compact power management IC for portable applications.
BASF said it will open an organic electronics R&D laboratory in Singapore devoted to nanotechnology and energy management, including the development of technologies for organic LED (OLED) displays and biosensors, and other printable electronics.
The $2.6 million investment, part of BASF's research expansion in Asia Pacific, will include a new project on organic photovoltaics in collaboration with the Institute of Materials Research and Engineering (IMRE).
Samsung SDI expects prices of its next-generation flat screens to fall to the same level as liquid crystal displays by 2010, a senior executive said.
Chung was referring to a new display technology - offering brighter screens and lower power use - which Samsung SDI hopes to mass-produce from the third quarter of this year and, by 2009, to use in television sets.
Total revenues for the first quarter of 2007 were $3.0 million, compared with $1.0 million for the same period last year. The increase was due to recognition of revenues from a license agreement and a development agreement signed in September 2006, and the sale of an inkjet printer during the first three months of 2007.
Net loss increased slightly to $7.7 million during the first quarter of 2007, from $7.6 million for the same period in 2006.
Ross Young, DisplaySearch's President and Founder says -
The technology behind this product is small molecule OLED material and a CMOS LTPS backplane produced at their joint venture with Toyoda. The red material is the highly efficient phosphorscent type from UDC fabricated by PPG. The blue is likely from Idemitsu Kosan. It is a top emission design which improves brightness, but it also uses a color filter which lowers brightness and makes it even more costly. They went with the color filter along with the RGB OLED materials to meet their color gamut requirements.
Samsung SDI, which has a more recent design, is able to achieve the same color gamut without the color filter. We would expect Sony’s next design to either exclude the color filter or go with white OLED material and maintain the color filter which would be bad news for UDC unless they went with UDC’s white material.
OLED-T today announced a new patented host material for OLED displays that delivers significant performance benefits compared with existing materials. The host layer is a crucial layer in the make-up of an OLED display as it impacts its performance including efficiency and lifetime. The new OLED-T material, called E746, is targeted as a direct replacement and upgrade path for aluminium quinolate (Alq3), the host material most commonly used throughout the OLED industry.
OLED-T has developed E746 for OLED displays in the mobile market such as mobile phones and digital cameras where its power consumption and lifetime performance benefits are expected to deliver improved product performance.
In fluorescent red and fluorescent green customer OLED display devices, OLED-T’s E746 material outperforms Alq3 in terms of energy efficiency, colour co-ordinates, lifetimes and voltage drift. E746 enables OLED displays to be manufactured with a current efficiency increase of between 30% and 50%, a power efficiency improvement of as much as 45 to 80 per cent and a lifetime increase of 100 per cent for fluorescent red and 200 per cent for fluorescent green.
