Braggone announces new optical nanostructures for display applications

Small Times

Oct. 10, 2006 — Optoelectronic materials supplier Braggone of Oulu, Finland, announced a new product line intended to enable end-user manufacturers of flat panel displays to cost effectively tune their newest product models to significantly better levels of quality and performance.

The material product line, LUXONE, is an enabler of next generation displays and flexible optoelectronic devices. The company says its nano-manipulation platform of optical and electrical coatings and nano-structures can be implemented directly into flat panel TVs, mobile phone and micro displays for brighter displays and less power consumption.

Typical components intended for manufacture with LUXONE are ultra thin and include efficient reflectors and light extractors that are implemented inside the display devices. The company’s current materials products are applied in digital displays used on current and next generation mobile phones and televisions, sophisticated semiconductors and logic chips for digital cameras and console game panels, and flash memories for PCs and MP3 devices.

“These optical and electrical layers were previously integrated into components through complicated and expensive high temperature vacuum processes and have also required complex patterning processes,” said Ari Karkkainen, one of the inventors of the technology and R&D director at Braggone, in a prepared statement.

“With Braggone’s technology and products integration scheme, the coating deposition and patterning can take place through a vacuumless process at low temperatures. Coatings are in liquid form prior to processing and therefore can be deposited with standard integrated circuit and flat panel industry process tools and even with conventional printing equipment,” he added.

For several years Braggone has been collaborating with the VTT Technical Research Centre in Finland in VTT’s printable electronics and optics center, the world leader in roll-to-roll optoelectronics processing. The focus of the work was to test Braggone’s product feasibility.
