QDOG marries the thin form factor of glass light guides with the color and brightness performance from QDs. “Display makers are currently focused on xQDEF, which is a barrier-free diffuser plate containing air-stable QDs,” Yurek told us Friday. Nanosys is positioning xQDEF as delivering improved performance and lower cost compared with QDOG (see 2012300003). XQDEF "combines multiple functions in a display so it’s very easy to adopt and will allow QD technology to further penetrate the mainstream TV market, including TVs priced under $500,” said Yurek. Nanosys announced a collaboration in early September with diffuser plate technology developer CYD to bring xQDEF components to mass production. QDOG ultimately found limited adoption in large-screen desktop monitors, including the HP Pavilion 27 introduced at CES 2019 (see 1901140008), but not in TVs, as Nanosys had envisioned. The Patent and Trademark Office declared Nanosys’ November 2017 QDOG trademark application abandoned Sept. 27 for the applicant’s failure to file a timely statement of use, agency records show.
