Luxell signs technology evaluation agreement with Philips

Philips Components and Luxell Technologies are to work together to evaluate the impact of Luxell’s ‘Black Layer’ technology on Philips’ PolyLED display structure.

Luxell Technologies has reached a technology evaluation agreement with Philips Components BV of Eindhoven, The Netherlands, under which the two organisations will work together on a technical evaluation of the performance-enhancing impact of Luxell’s ‘Black Layer’ technology on Philips’ organic light emitting polymer (PolyLED) display structure, an organic electroluminescent (OEL) based flat panel display technology.

Philips Components, a developer of organic emissive displays based on its PolyLED technology, is due to launch matrix displays for mobile phones from its factory in Heerlen (The Netherlands) by the end of this year.

‘Black Layer technology’ improves contrast and prevents information washout caused by reflection. It uses reflection-causing ambient light against itself, and makes the cause of most reflection – the display counterelectrode -part of the solution. The Black Layer stops most reflection before it can take place.

It is based upon a phenomenon called ‘optical interference’ which allows that if one can reflect light back onto itself 180 degrees out of phase, the incident light should cancel with the reflected light, making both, in effect, disappear.

OEL flat panel displays are considered the next-generation products in the global electronic display industry. DisplaySearch, a leading technology research firm, predicts that annual sales of consumer-related organic flat panel displays will grow to USD$3.3 billion by 2005 from USD$24 million in 1999.
