A Canadian company claims it has made a breakthrough on colour flat panel screens for the computing and television markets, which should significantly reduce prices.
Westaim says it has created a stable blue phosphor, which will allow the creation of electro-luminescent (EL) displays. The lack of that element previously restricted EL devices to monochrome. Displays using the full colour system can also be viewed from practically any angle.
Although a number of manufacturers offer flat displays, EL can be produced as a solid state device, which makes it cheaper and extremely rugged, said Westaim.
Fabrication of the parts is also far less expensive and gives higher yields than the other technologies now available. Adrian Kitai, professor of engineering physics at McMaster University in Canada, said: ?Westaim has made a big step forward in EL technology by demonstrating full colour in colour by white technology for the first time.?
Shares in the company soared on news of the invention.
