printing process. A second phase of work will now commence with our partner to reach pilot scale and to market the technology to the global electronics sector.
“The printed electronics market is forecasted to be in the order of $10B by 2015 in multiple application areas from displays to photovoltaics,” commented Mike Edwards, VP of Sales & Marketing. “The colla- boration with PETEC has served as a concrete vali- dation of our Onto™ interlayer adhesion technology and we look forward to continuing this relationship as we seek global licensing partners in the area of printed electronics”.

he new TOPLED Compact 4520 from OSRAM Opto Semiconductors is one of the smallest
for screen backlighting and is the first LED for this application to have a UX:3 chip. It is therefore ideal for pulse mode, can be loaded with a very high cur- rent and helps produce razor sharp pictures. This tiny light source with a brightness of 35 lm (at 150mA) and an efficiency of 72 lm/W is suitable for single or double-sided injection of light into light guides up to 2mm and covers a color space of more than 100% sRGB.
Thanks to its UX:3 chip, which offer excellent linea- rity between current and brightness, it is brighter in high-current pulse mode than all the LEDs based on other chip technologies. Like the other members of the TOPLED family, the TOPLED Compact 4520 is
flat encapsulated and does not have a lens. It is the- refore ideal for single or double-sided injecting in light guides. The tried and tested TOPLED package measures 4.5 x 2.0 x 0.8mm. It is synonymous with reliability and can be manufactured in large volumes. “The TOPLED Compact 4520 has been designed specifically for super flat displays”, said Winfried Schwedler, Marketing Manager Backlighting at OS- RAM Opto Semiconductors. “Its extreme brightness and high-current pulse mode help produce razor sharp high-contrast images with no wipe effects.” htttp://www.osram-os.com
cientists from Philips Research (NYSE: PHG) have developed the first-ever organic light
emitting diode (OLED) module that can be po- wered directly from a mains electricity supply. The prototype opens the door to OLED systems that can be directly plugged into standard power out- lets without the need for bulky power management circuitry. This will reduce the bill of materials and simplify luminaire design for future OLED-based systems aimed at mass-market general illumination applications.
“We have combined proprietary interconnect and packaging technology to create this demonstrator,” says Dr. Dirk Hente of Philips Research. “We’re already seeing AC-driven LEDs coming onto the market. Our prototype marks a breakthrough step towards a similar evolution in OLEDs.”
Eliminating the need for driver electronics could bring many advantages for luminaire manufacturers. Because it reduces the number of components in a finished system, it makes system integration and as- sembly simpler, improves end-product reliability and
