Sony to use quantum dots in 'Triluminos' Bravia HDTVs

Quantum dots to increase color range by 50 percent

Details of 'Triluminos,' a feature of Bravia HDTVs using quantum technology demonstrated at CES by Sony, have been made available. Originally appearing in televisions in 2008 before being pulled due to the costs involved, the technology relies on nanoscale particles called 'quantum dots' in order to increase the color range of LCD televisions by around 50 percent.

The quantum dots, according to a representative of QD Vision speaking to the MIT Technology Review, emit specific wavelengths of light, which can be tuned by changing their size. Starting with pure blue LED light, the quantum dots tuned to emit pure red and green light are stimulated by the light, which in turn pass through conventional RGB light filters which usually allow other aspects of the color spectrum through, such as oranges and impure reds. By allowing only pure red through the red filter and so on for other filters, it helps avoid washed-out colors.

Sony will be using the technology in upcoming LCD displays, not the more-expensive OLED versions, and will be providing details of specific models and price ranges of Triluminos HDTVs in the future.
