How to choose a fantments TV?

Quantum dots – these are tiny nanoparticles that are able to modify the light falling on them. They recreate a wide range of colors and thus facilitate the adjustment of light intensity at the pixel level, allowing for a deeper level of black.

What’s more, they give the recipients better comfort of watching in a number of various aspects – they provide uniform luminance, consistent colors when looking at any angle, minimize exposure to blue light, give high brightness, loyalty of colors and the frequency of image refreshment.

Today, the emanation of this technology are QLED, Neo OLED and QD OLED matrices – these terms can be found by going to the RTV equipment store today.

What should you consider when buying a TV with a quantum dot?

First, dot density.

The actual quality of the TV and the broadcast image is determined, among others, by how densely “packed” microscopic semiconductors emitting light are densely. To get a lively, rich image details characterized by better color expression-i.e. features from which QLED and QD-OLED displays are known-a higher degree of packing of quantum dots in the QD layer is necessary. To make the image visibly better, the dot density in the matrix material should be at least 3000 ppm (number of points per millimeter of screen surface).

Secondly, the quality of the matrix

Color visualization must be not only alive, but also resistant to the passage of time. Displays with quantum dots have a simple and very efficient structure, e.g. compared to LCD screens. QLED screens eliminate the need to use the phosphorus layer, because it is the QD layer itself – in combination with blue backlight – increases the level of brightness and provides more expressive colors.

The image quality is also influenced by the fact that the matrix with quantum dots is illuminated by organic diodes (QD-OLE), which consists of a layer of thin-layer transistors (TFT) emitting blue light and layers of quantum dots illuminated by it.

In both cases-I QLED, I QD-OLED, a special “foil” with the appropriate compaction of quantum dots for a long time is of key importance for ensuring the highest quality of the image and behave for a long time.

It is also worth remembering that QLEDs also have the advantage here that they use the technology of inorganic dots, which protects the displays from firing, thus maintaining high image quality despite the passage of time.

Thirdly, it is worth considering environmental issues.

At the early stages of developing televisions with quantum dots technology, cadmium was considered the best -suited material for this purpose, because it allowed for key values, such as excellent color reproduction and a high contrast factor.

However, the toxicity of cadmium and the adverse impact of this element on the natural environment has become an important obstacle to the commercialization of this technology. Today, the use of cadmium in consumer electronics is allowed, but is subject to rigorous restrictions under EU law.

In response to these challenges, Samsung, one of the first manufacturers implementing quantum dots technology, was developed and patented in 2014. The first material in the world allowing the use of quantum dots material – nanocrystal free from cadmium. The following year, the manufacturer commercialized this technology, introducing SUHD groundbreaking TVs to the market (by the way Samsung remains the only counting brand that offers this technology on the market).

Since 2014, the company collected extensive specialist knowledge and constantly worked on the development of dot technology, registering a total of over 150 patents in this area. In 2017, he released the first range of QLED TVs, which established a completely new standard in the Premium class product segment. After all, the use of metallic quantum dots allowed Samsung TVs to meet the requirements developed by Digital Cinema Initiative DCI-P3 standards and for the first time achieve 100 % color intensity, thus guaranteeing unparalleled impressions when it comes to the possibility of their realistic reproduction.

All these development works led to the introduction of QD-OLED TVs that have gone throughout history at CES 2022, winning a distinction in the category of best innovation for the integration of QD technology in OLED class screens.

When looking for a TV for yourself, it is worth paying special attention to these three elements: from the issue of the level of compaction of dots through the quality of the matrix to the use of non -harmful materials.
