Quantum TV rivals plasma displays

摘要

After five years of secret research, two of the world's biggest electronics companies say they have developed a picture display technology that more than halves the power consumption of large flat-screen television sets. Today's increasingly popular plasma TV screens, with a viewing area measuring 40 inches (100 centimetres) and more, consume at least 400 watts, making them a serious contributor to global warming. The new surface-conduction emission display (SED), jointly developed by Japanese firms Canon and Toshiba, will reduce this to less than 150 watts, the manufacturers claimed last week.
