Quantum dot technology enhances color displays

New Scientist : Sony has developed a flat-panel electronic display that is more energy efficient and provides richer color than conventional LCD displays. The new display uses quantum dotsâmdash;tiny semiconductors that confine electric charge and emit light. Each dot’s color depends on its size and shape. Although each spans just 10% of the visible spectrum, the dots can be mixed to produce 100% of the color range visible to the human eye. The company that developed the technology, QD Vision , claims that its Color IQ technology provides “the most radiant reds, brilliant blues and gorgeous greens you will ever see.” Other benefits of the new technology include lower costs and the potential for extremely thin displays.
