More lifelike colour TV technology studied

Swiss scientists have unveiled a new technology that could lead to video displays faithfully reproducing a fuller range of colours than do current models. The invention, based on fine-tuning light using microscopic artificial muscles, could turn into competitively priced consumer products within eight years, the scientists say. ‘State-of-the-art displays such as LCD displays can only reproduce a limited range of colours because the three mixing colours red, green and blue are determined during the time of production,’ said Manuel Aschwanden, a nanotechnology expert at the Swiss Federal Institute of Technology in Zurich, Switzerland. Aschwanden and colleague Andreas Stemmer believe such limitations can be avoided by changing the fundamental colours themselves, not just their brightness. The research appears online in Optics Letters, a journal of the Optical Society of America, and will also be published in the journal’s September 1 issue. (UPI,August 18, 2006)
