Quantum dots have attracted consideration as next-generation materials for a variety of functions together with shows, medical gadgets and photo voltaic cells. In 2014, Samsung Electronics developed the world’s first no-cadmium quantum dot materials and efficiently commercialized quantum dot expertise with its SUHD TVs. Since 2017, the corporate has continued to construct on its legacy of quantum dot mastery by QLED — its personal quantum dot TV sequence. Samsung Newsroom explored how quantum dots are taking Samsung shows to the subsequent stage.
Quantum Dots: The Next Generation of Display Innovation
Quantum dots are ultra-fine semiconductor particles which might be tens of 1000’s of occasions thinner than a human hair. Since inception, their bodily traits that enable them to supply the best stage of colour accuracy and brightness amongst current supplies had them positioned to revolutionize show expertise.
When utilized in shows, quantum dots help a large colour gamut that carefully matches colours perceived by the human eye and facilitate pixel-level gentle adjustment for extra correct black ranges. Emitting gentle in all instructions, quantum dots ship uniform luminance and constant colour from any viewing angle whereas minimizing blue gentle publicity for a extra snug viewing expertise.

What Sets Quantum Dot TVs Apart: Content, Film Quality and No-Cadmium Technology
The TV trade continues analysis and growth into the commercialization of quantum dots as the fabric turns into a game-changer in show expertise. For that purpose, quite a lot of quantum dot TVs have hit the market lately — providing a variety of choices to clients.
However, key variations in quantum dot TVs lie in how the expertise is carried out and the general high quality of the show. To guarantee a premium viewing expertise, components resembling the quantity of quantum dot content material, the standard of quantum dot movie and using no-cadmium supplies have to be thought-about.
▲ Factors to think about when choosing a high-quality quantum dot TV
Quantum Dot Content
The true high quality of a quantum dot TV is outlined by its quantum dot content material. The quantum dot layer requires a minimal of 30 elements per million (ppm) of the fabric to realize the vivid, wealthy image high quality and colour expression that solely quantum dots can ship.
Quantum Dot Film
Quantum dot shows have an easier and extra environment friendly construction in comparison with LCDs. Samsung QLEDs get rid of the necessity for a phosphor layer, enhancing gentle and power effectivity whereas delivering extra vivid colours. A quantum dot OLED (QD-OLED), which consists of a thin-film transistor (TFT) layer,1 a self-emitting gentle supply and a quantum dot movie that makes use of the sunshine emitted from the sunshine supply, takes a step additional enhancing image high quality. In both case, a devoted quantum dot movie that accommodates enough quantum dots is essential in delivering top-class image high quality and longevity.

No Cadmium
In the early phases of growing quantum dot TVs, cadmium was important to reaching the important thing advantages of quantum dots resembling colour copy and distinction ratio. At the time, cadmium was thought-about essentially the most environment friendly materials for producing quantum dots.
However, cadmium’s toxicity turned a big impediment to the commercialization of quantum dot expertise. The factor posed critical threats to the surroundings — making its widespread use troublesome regardless of being essentially the most appropriate materials for implementing quantum dot expertise.
In response to this problem, Samsung developed the world’s first no-cadmium quantum dot materials in 2014 and efficiently commercialized quantum dot expertise with its SUHD TVs within the following yr to open a brand new period of quantum dot TVs.
