RE: Despite Challenges, QD Vision Laid the Foundation for Quantum-Dot Displays23 May 2022 15:29
Feeks: Although electroluminescence is of huge importance, QDVision went broke while failing to solve the technology. The following article describes their path to failure and eventual infringement on Nanosys technology. Their only recourse was to accept a buyout from Samsung. It is not clear that Samsung gained much from the patents, except to be able to claim that they owned quantum dot patents.

"According to the lawsuit filed by Nanosys, 12-year-old QD Vision initially focused on developing quantum dots that use “electroluminescence” properties, whereby electricity sent through the nanocrystals produces light. That’s different from the “photoluminescence” technique used by Nanosys, in which light is used to excite the semiconductor materials. But Nanosys alleges that when QD Vision hit a wall with its initial approach around 2008, the company switched to developing quantum dots that use the same method as Nanosys—and violate its patents.
“When QD Vision’s own technology failed, the company chose infringing on Nanosys’s patents over taking the time to innovate,” Hartlove said in a press release."
