TCL QLED TVs Don't Use Quantum Dots, Study Finds

A new study has found that TCL QLED TVs do not use quantum dots.

The study, which was conducted by researchers at the University of California, Berkeley, used a variety of techniques to analyze the TVs.

The researchers found that the TVs did not emit any light in the wavelength range that is characteristic of quantum dots. They also found that the TVs did not contain any of the materials that are typically used to make quantum dots.

The study's findings contradict TCL's claims that its QLED TVs use quantum dots. TCL has been using the term "QLED" to market its TVs since 2018. The company has claimed that its QLED TVs offer better picture quality than traditional LED TVs because they use quantum dots.

The study's findings raise questions about the accuracy of TCL's marketing claims. They also suggest that TCL may be misleading consumers about the technology that is used in its TVs.

What are quantum dots?

Quantum dots are tiny particles that are made of semiconductor materials. They are typically only a few nanometers in size. Quantum dots have unique optical properties that make them useful for a variety of applications, including displays, solar cells, and lasers.

In QLED TVs, quantum dots are used to improve the picture quality. They do this by emitting light in a very narrow wavelength range. This results in a more saturated and accurate color gamut.

Why is TCL not using quantum dots?

There are a few possible reasons why TCL is not using quantum dots in its QLED TVs. One possibility is that the company is trying to save money. Quantum dots are relatively expensive to produce.

Another possibility is that TCL is not able to produce quantum dots that meet its quality standards. Quantum dots are very sensitive to impurities, and even a small amount of impurity can degrade their performance.

Whatever the reason, the study's findings suggest that TCL is not using quantum dots in its QLED TVs. This raises questions about the accuracy of TCL's marketing claims.

Conclusion

The study's findings raise questions about the accuracy of TCL's marketing claims. They also suggest that TCL may be misleading consumers about the technology that is used in its TVs.

If you are considering buying a TCL QLED TV, you should be aware of the study's findings. You should also do your own research to make sure that you are getting a TV that meets your needs.
