Nanosys also won an award in the small-exhibit category for its quantum-dot TVs. Nanosys’s Display Week demonstration included three matched 65-in. UHD TVs (Fig. 6). Each of the sets used the same color filters, underlying LEDs and direct-lit backlight structures. They were also driven at the same settings from the same content. The only difference was in the phosphor used to create white light in the backlight. These were: conventional white LEDs, Nanosys’s Quantum-Dot-Enhancement Film, and Nanosys’ Cadmium-Free Quantum-Dot- Enhancement Film. The differences in color performance without noticeable brightness loss were striking. Rec.2020 color-gamut coverage ranged from <60% for the white LED set to ~75% for the set with cadmium-free quantum dots to >90% for the set with quantum dots. This demonstration showed that cadmium-based quantum dots have a significant performance advantage over other phosphor materials and that Rec.2020 is achievable today. •Read More
The image quality of OLED is, theoretically, under pressure from new LCD screens enhanced with quantum dot technology.Read More
Display experts, Displaymate, say QDs will revolutionize LCD displays over the next five years, bringing them on a par with the OLED screens favored by Apple’s main competitor.
Quantum Dot is an enhancement film layer that improves the color performance of LCD screens, like the Retina. It can also be used to enhance the color performance of TVs. Quantum Dot technology has the advantage of being able to work with existing display production lines – it’s a drop-in technology with no significant capital investment required.
What’s doubly interesting is that there are already quantum dot technologies on the market. I wrote back in the summer that inventors Nanosys and fabricator 3M were ready to roll with quantum dot enhancement film (QDEF).Read More
