“Manufacturers are trying to reduce the concentration of quantum dots to reduce costs, but we have now reached undetectable levels of quantum dots. This is dangerous for the industry as a whole and could undermine consumer whatsapp number list confidence in the products .”
The use of phosphorus in combination with quantum dots in TCL TVs has been documented before . In a 2024 video, Pete Palomaki, owner and chief
Phosphorus Contributes to scientist of quantum dot firm Palomaki Consulting, took apart TCL’s budget 2022 55S555 QLED TV.
Palomaki concluded that the quantum dots
In this TV were integrated into the diffuser rather than a separate optical film. He also determined that a red phosphor called KSF and
Phosphorus Contributes to a green effective ways to use social media for your business phosphor known as beta-sialon play an important role in producing color on the screen.
In his video, Palomaki noted, “In the green spectrum, I get about 10 percent from the quantum dots, and the remaining 90-plus percent from the phosphorus.” He also said that about 75 percent of the TV’s red color reproduction capabilities come from the KSF,
Phosphorus Contributes to and the rest from the quantum dots. However, Palomaki emphasized that his calculations do not take into account the recycling of light in the backlight unit,
which would likely “increase the contribution of the quantum dot . ”
Palomaki did not specify Phosphorus Contributes to
What other contribution quantum dots could make and declined to comment for this story.
Another video showed an example of a TCL QLED TV, which Palomaki said had phosphors around the LEDs. However, it still used quantum dots to calling list convert most of the color .
TCL isn’t the only brand using phosphors to improve the color rendition of its QLED TVs and potentially reduce manufacturing costs. There’s a spectrum of TV designs, from phosphor-only to quantum dot-only, with everything in between.
Even Samsung, a company
That has criticized TCL for its lack of detectable quantum dots, has reportedly used phosphors to handle some color tasks that are typically handled solely by quantum dots in full quantum scan TVs.
