Can nanotechnology save LCD TVs?
Many of us don't like to admit it, but televisions are an important part of our lives. Technology has improved the quality and convenience of TVs and has given us a whole new set of choices - high definition, plasma, and liquid crystal displays. With an estimated 66 million sets to be sold this year, flat-screen LCD televisions are the most popular choice. Much of the reason behind the popularity of these high-tech wonders is the decrease in price that happens with most cool technology - a few years after they have been on the market. But, for the popular LCD TV, a shortage of a key compound used to produce LCDs may force manufacturers to raise prices. Electronics suppliers are facing a shortage of the rare metal indium, a co-product of zinc mining. Indium is a rare, malleable and easily fused metal, similar to aluminum, which is used to make indium tin oxide (ITO), the standard transparent electrode used in nearly all flat panel displays and microdisplays. Indium is expensive and scarce and demand is increasing. According to Displaybank, the demand for indium was 861 tons in 2006 and may reach nearly 2000 tons by 2011. Five years ago, indium was about $100/ kg; now it costs $800/kg. Displaybank expects the total sales of indium in 2007 to be $533 million. But, geologists say the cost of indium may not matter soon, because the earth's supply of it could be gone in four years. This could put a serious damper on that 52" LCD screen you've been dreaming about. Fortunately, with the help of nanotechnology, a team of scientists in Japan have developed a new material that may replace the need for indium in LCD production.
