What are the advantages and disadvantages of quantum dot TV, is it worth buying?

The advantages of quantum dot TV are very high color purity, relatively energy efficient, long service life. The disadvantage is that the raw material contains carcinogenic cadmium, if volatile may affect human health. With the progress of technology, quantum dot TV is also more and more safe, more worth buying.

Quantum dots are a very cutting-edge nanomaterials, which has a unique electrical characteristics. The diameter size of the quantum dots determines its ability to emit different pure and high quality monochromatic light when stimulated by light and electricity. This makes it has the advantage of full color gamut display, the color gamut value can reach one hundred percent NTSC color gamut far more than the current popular Oled one hundred percent NTSC color gamut coverage. By adjusting the quantum dot grain size to achieve precise adjustment to produce different colors, effectively enhancing the color realism.

Compared with the advantages of full color gamut display, other aspects of quantum dot TV technology are still relatively outstanding. A large amount of research data shows that quantum dot TV technology can achieve ninety-five percent close to natural light and broadband continuous spectrum, color purity is very high. Quantum dot TV technology can realize stronger energy saving than traditional TV, higher efficiency. In terms of materials, it can realize not to use the glass base material and use inorganic materials, thus realizing strong stability, long service life and not easy to age. This is why Quantum TV is known in the industry as a better TV to replace OLED.

Disadvantages of quantum dot TV technology: quantum dot TV technology still has a certain disadvantage, in 2015, only TCL released a 55-inch TV, and its price is as high as 1,299 yuan, while the market 4K Ultra HD LED TV is just about 5,000 yuan. The price difference between the two is more than 2 times, so it can be said that the price is its most fatal weakness. There is also the health problem, because the raw material of quantum dot contains cadmium, there is the problem of cadmium volatilization. And cadmium is a recognized carcinogen, if the consequences of volatilization is unimaginable.
