How Quantum Dot Technology in Samsung TVs Works

Quantum Dot Samsung

The SUHD technology is currently the flagship in terms of picture quality TVs Samsung . The picture quality improvement that SUHD televisions achieve over other conventional televisions is based on three key technologies: Quantum Dot Color , HDR 1000 and the SUHD Remastering Engine image scaling system  . Today we want to tell you more in depth about the Quantum Dot technology that Samsung televisions use to try to get the best image on the market.

Quantum Dot is a technology that incorporates nanoparticles panel of the TV for improving the color gamut , thus leading to the highest level to the LED panels. To understand it better, let's quickly summarize how normal LED panels work. We basically have a blue LED light as the main source of illumination . This makes blacks the screen look brighter than they should , pulling more dark gray and other colors look less vibrant .

This problem with colors and blacks has led manufacturers to continue looking for a way to improve these types of panels, without having to switch to expensive OLED panels. Nanocrystal technology is nothing new, as it has been available to everyone for many years, but each manufacturer has wanted to implement it in a specific way. The function of the nanocrystals will be to filter the blue light produced by LEDs, breaking it up and obtaining a white light that contains all the colors of the spectrum . On a practical level, this translates into deeper blacks and more intense colors .

Samsung has improved this technology in several ways. On the one hand, they have been able to manufacture Quantum Dot panels without the need for cadmium , a compound that can be harmful to health. On the other hand, they use a technique of  coating the nanoparticles filter called Quad-layerEach nanoparticle is protected with a capsule . Thanks to this, its possible defects and the incidence of oxidation or humidity are reduced . In addition, the level of impurities in the nanoparticle layer is reduced to a minimum, making the luminosity increase by 15% and increasing its durability .

In addition, Samsung's Quantum Dot TVs use Ultra Black technology with a Moth-Eye panel , based on the reticule of moths' eyes, to minimize reflections . How do they do that? They have created a structure of nanometric cones in which light is absorbed by the panel until its incidence is attenuated by 99.7% . The combination of this type of panel with Quantum Dot technology achieves even darker blacks .

Finally, to further improve Quantum Dot technology , Samsung televisions mount a 10bit panel , thus achieving greater color depth . The difference with a conventional panel is that each of the pixels is capable of processing a greater amount of information . This ensures that the television covers 96% of the DCI-P3 color space , supporting a BT 2020 color input .

In short, what Samsung's Quantum Dot achieves with all its technologies is greater color accuracy , thus approaching a color reproduction much more faithful to reality, as we could see in the analysis of the Samsung UE65KS9000 television .
