This statement is incorrect. The 2013 900a series used quantum dot, the 2014 900b series does not.
Three of Sony's 2013 TVs will use quantum dots in their backlighting, in the guise of QD Vision's Color IQ tech (the 65X900, 55X900 , and 55W900). http://www.cnet.com/news/what-are-qu...-your-next-tv/
Sony also touts the Triluminos color on this and its other 4K TVs. Unlike last year's Triluminos Sonys, however, the 2014 version of this feature no longer uses the Quantum Dot technology supplied by QD Vision, Inc. Sony says it now has an in-house version that uses the same branding, but beyond the marketing line of "more colors to produce a more-vibrant picture," Sony wouldn't tell us how the "new" Triluminos technology differs from standard white LED display tech
